4 Overview example initial section Fields of application Overview Example initial section / presentation top chord level General The WACO Roof Covering System 600 roofing system is a modular system which can be erected on almost every scaffolding system. The system is adaptable to multiple fields of application due to its capability to be optimally adjusted to both the local and technical conditions. Handy light-weight components of aluminium as well as mostly screw-free connections are the prerequisite for quick and simple erections and transports. Therefore, the use of the WACO Roof Covering System 600 roofing system is cost-effective also with short standing times. 8 9 Weather protection roof on scaffoldings The standard design version of the WACO Roof Covering System 600 roofing system is applicable for weather protection roofs up to a span width of 27.5 m on scaffoldings according to DIN EN / DIN EN covering all sides with sheeting Mobile shelter Ridge girder, Aluminium 09 Girder support 200, Steel 02 Roof girder, Aluminium 10 Triangular bracket, Steel 03 Longitudinal ledger, Aluminium 11 Keder rail with tilting pin 04 Diagonal ledger, Aluminium 12 Tilting pin coupler 05 Ridge ledger, Aluminium 13 Keder rail 06 Eave bracing, Aluminium 14 Keder rail holder 07 Eave ledger, Steel 15 Castor 08 Girder support 400, Steel 16 Assembly frame 12 Due to the low weight of the aluminium structure (approx. 10 kg/m²) the WACO Roof Covering System 600 roofing system is perfectly suitable for mobile shelters. On level ground, even larger shelters can be manually moved without any problems. The maximum span width is 16 m. Protection roofing for excavations For the covering of excavation pits, channels or other earthworks the WACO Roof Covering System 600 roofing system can be used without side wall. Mono-pitch roof If the on-site conditions require this, the weather protection roof can also be erected as a mono-pitch roof. The support of roof girders is possible on scaffoldings, lattice girders or wall brackets. 8 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem 600 9

5 Safety instructions Safety instructions For the assembly of the ALFIX weather protection roof WACO Roof Covering System 600 and its use, also by sub-contractors, the following regulations must be observed: accident prevention regulations for construction work no. 37 (UVV Bauarbeiten VBG 37) and the instructional pamphlets no. 410 of the Construction Trade Association (Merkblätter der BauBG) Safety of roof work, and the relevant DIN standards. Only qualified employees are entitled to do such work To the extent possible the assembly and the pulling of the sheeting should be done on the ground. So, the assembled (incl. sheeting) roof sections shall be lifted onto the supporting scaffold, and only the pulling of the Keder roof sheeting of the intermediate sections should be done after the roof has been put in place. Always use rope fasteners for this work If the roof of a stationary weather shelter needs to be opened, a walkway should be arranged at the supporting frames around the eaves in the form of brackets provided with decks As soon as the wind force gets higher than 6 on the Beaufort scale all erection activities for the weather protection roof on the supporting frame must be suspended. Any opening of the roof should be avoided. The roof sections may only be put in place when there is no wind. Mobile shelters may only be covered with sheeting after they have been properly anchored Sub-contractors are not allowed to stand on the weather protection roof. All work on the roof, such as roof openings, must be performed from the walkway Openings in the weather protection roof If roof sections are to be opened during construction, provision should have been made during pre-assembly already. To the extent possible openings should be arranged in the eaves area because opening and closing will be easier there. Depending on the size of the required opening it may be necessary to omit bracings in the relevant roof sections. If so, the roof sections adjacent to the roof section to be opened should be designed as bracing bays. Depending on the kind of installation the Keder roof sheeting has to be provided with long scaffold ropes to allow a safe opening and closing of the sheeting from the walkway. If it becomes necessary in special cases to open the weather protection roof at an unexpected point or even remove entire trusses, this work has to be performed by qualified personnel only. Always wear a safety rope and stay within the closed roof section. Make sure that all openings are closed at the end of the working day. Do not open the roof when the wind force is 6 or above on the Beaufort scale. 10 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

6 Erection Erection 5.1. Types of roof sections 5.2. Erecting the roof trusses Initial section It is the first front-side roof section. This section needs special bracings because it usually has to absorb forces from the gable wall sheeting. Extension section Extension sections are roof sections located between the braced roof sections. Maximum four extension sections may be arranged between braced roof sections. After the required span (see paragraph 7) has been determined the roof girder elements can be pre-assembled. For this purpose place the roof and first girder flat on the ground. Provide the roof girders (incl. pre-assembled tube connectors and Keder rail connectors) with the supplied rubber seals. Slip the square opening of the latter onto the Keder rail connectors of the roof girder. Now, the girder elements can be fitted into each other. We recommend placing squared timber under the girders to facilitate screwing. Secure the connections between the roof girders at the top and bottom chord using 2 hexagonal-head bolts M 14 x 60 each, at the Keder rails using two Allen screws M 12 x 40 each. In the chord area the girders must be connected with four hexagonal-head bolts for each chord and butt, and in the Keder area with four cylinder-head bolts per butt. Bracing section The bracing section is used when the weather protection roof has more than four extension sections, or together with starter section, extension sections and end section is longer than six roof sections (see overview). Roof-end section The bracing of the roof-end section is similar to that of the starter section. It is located at the opposite gable end of the starter section. In the material table on page 14 the roof-end section differs from the starter by a material difference, because the roof-end section extends, as does the extension and bracing section, the weather protection roof and does not form an independent roof section as does the starter section Roof bracing Ridge ledger Ridge ledgers are provided in the ridge area of every roof section at the central vertical tube in the bottom chord. The ridge ledgers have on both sides goose-necked ends of different lengths ensuring that despite the ridge ledgers being mounted on the same vertical tube every ridge ledger can be mounted horizontally Eave bracing Ridge ledger Eave bracings are provided in the starter, bracing and roof-end sections at the outermost vertical tube on the eaves side in the top chord, i.e. two eaves bracings are provided in each braced roof section. Installing the eaves bracing 12 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

7 Erection Erection Longitudinal ledgers Longitudinal ledgers are provided in the top chord area (over the Keder rail) on the vertical tubes, in the bottom chord section (below the Keder rail) on the bottom chord. Make sure that all longitudinal ledgers in the bottom chord area are mounted at the location described because otherwise an unobstructed hanging of the Keder sheeting may be prevented and water may collect. When it comes to mobile shelters, the longitudinal ledgers are also provided in the walls at the triangular columns in addition to their use in the roof area Position of roof bracings within the individual section types Initial and roof-end sections: Longitudinal ledger every 1.5 m on top chord every 1.5 m on bottom chord Bracing sections: Diagonal ledger every 1.5 m on top chord (crossed) every 1.5 m on bottom chord, single-crossed on ridge Eave bracing on both sides on top chord Diagonal ledgers Make sure that the diagonal ledgers in the bottom chord are provided as close as possible to the bottom chord to ensure an unobstructed hanging of the Keder sheeting. Diagonal ledgers are provided in the top chord area (over the Keder rail) and on the vertical tubes, in the bottom chord area (below the Keder rail) on the vertical tubes, the initial and the roof-end section and in the bracing sections. In the ridge area the diagonal ledgers must be provided crosswise in the top chord at the vertical tube connectors. When it comes to mobile shelters the diagonal ledgers are mounted in the triangular columns of the wall in addition to the use in the roof area. Longitudinal ledger every 1.5 m on top chord every 1.5 m on bottom chord Extension sections: Longitudinal ledger every 1.5 m on top chord every 4.5 m on bottom chord Diagonal ledger 1.5 m on top chord, single every 1.5 m on bottom chord, single-crossed on ridge Eave bracing on both sides on top chord Diagonal ledger Longitudinal ledger After the first diagonal and longitudinal ledgers have been erected (from one side to the other) the roof section will stand independently Eave ledgers Eave ledgers are used to fasten the roof sheeting. They are mounted on the girder supports, assembly frames and triangular columns with tilting pin couplers or Keder rails with tilting pins. The Keder roof sheeting can then be fastened to the eaves ridge with a scaffold rope or a belt with latch. The picture shows the complete reinforcement with longitudinal and diagonal ledgers. 14 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

8 Erection Erection 5.5. Assembly of roof sections Usually assembly starts with the construction of an initial section. For this purpose two pre-assembled roof trusses must be set up (for smaller spans by hand, otherwise by crane) and put onto an assembly frame of scaffold components or secured by bracing. The roof trusses are to be placed at grid distances and parallel to each other. Now, the roof bracings are to be assembled as per paragraph 5.4. Make sure that the roof bracings are always assembled starting from the eaves upwards to the ridge and then away from the ridge towards the eaves One Keder sheeting on each roof side, overlapping at the ridge (2 parts) Two Keder rails allow an overlapping of the Keder sheetings. This version is used for medium spans of up to 19.0 m One Keder sheeting on each roof side, one Keder sheeting at the ridge overlapping the two roof-side sheetings (3 parts) This version is used for large spans. The outer sheetings are pulled into the lower Keder rail and the ridge sheeting into the upper Keder rail. Please refer to material tables on pages to find the Keder sheetings suitable for your particular application. Thus, any distortion or twisting of the roof girders will be avoided. If during assembly the standing height of the personnel exceeds 2.0 m from the ground, use a tower scaffold. If several roof sections are to be lifted at the same time, up to three roof sections must be pre-assembled in the same way Fitting the roof sheetings Two Keder rails on each side in the central chord of the roof girders are used to fit in the Keder sheetings which can be done in different ways. The ALFIX roofing system WACO Roof Covering System 600 provides three different opportunities to put the Keder sheeting in place Eave-to-eave Keder sheeting (1 part) This version is used for short spans only because it requires large sheeting lengths. 5.7 Fastening the roof sheetings In accordance with the possibilities described above, the Keder sheetings are laid out along the eaves of the finished roof section and are inserted into the relevant Keder rail. The scaffold rope, fixed at eye at the front side, is used to pull the Keder sheeting in the desired direction. Since the standing height of the workers 16 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

9 Erection Erection often exceeds 2.00 m, the sheetings must be pulled in from a tower scaffold. Then, the Keder sheetings are to be fixed as follows: Keder sheeting from eave to eave (1 part) After the roof section has been assembled, the Keder sheeting must be fixed on the supporting scaffold using quick-lock chord closing systems at the assembled eaves ledgers. See eaves ledgers paragraph Before the Keder sheeting is mounted on the supporting scaffold it has to be temporarily fixed at the roof girders One Keder sheeting on each roof side, overlapping at the ridge (2 parts) The Keder sheeting shall project over the ridge by approx. 2 m towards the other roof side. In this area the Keder sheeting has to be secured laterally at the vertical tubes of the roof girders by scaffold ropes used for pulling it in. In this process, the sheeting in the lower Keder rail is fastened at the vertical tubes in the bottom chord and the sheeting in the upper Keder rail - in the vertical tubes in the top chord. In the eaves area the sheeting is to be fastened after assembly of the roof section on the supporting scaffold by belts with latches at the assembled eave ledgers. See eave ledgers, paragraph Before the sheeting is mounted on the supporting scaffold it has to be temporarily fixed to the roof girders in the area of the eaves One Keder sheeting on each roof side, one Keder sheeting at the ridge overlapping the two roof-side sheetings (3 parts) In the roof area the Keder sheetings have to be fastened at the vertical tubes of the bottom chord with the scaffold ropes and in eaves area at the assembled eaves ledgers. See eave ledgers, paragraph Transportation of roof section by crane Prior to the assembly of roof girders to roof sections, it is required to observe that the maximum number of roof sections to be transported by crane with one single hoisting is three. Each hoisting by crane must contain at least one braced roof section. If there is no braced roof section available for a planned hoisting by crane due to an unfavourable partition, an extension section must be braced in the same way as a bracing roof section. If it is necessary to lift one single roof girder, flexural strength must be additionally given to this girder by means of a lattice girder or steel tubes to be positioned alongside the roof girder; otherwise there is a danger of it buckling. To provide an attachment point for the crane lifting means when transporting several roof sections, lattice girders are mounted alongside the upper third points (see paragraph 7) of each roof side, on the top chord of the roof girders. Before the Keder sheeting is fitted to the supporting scaffolding, it must be temporarily fastened at the roof girders. The ridge sheeting is fastened at the vertical tubes of the top chord using the scaffold ropes on both sides of the ridge. 18 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

10 Erection Erection 5.9. Placing the pre-assembled roof sections onto the supporting scaffold After pre-assembly has been completed, the roof sections can be placed onto the supporting scaffold. The requirements for the supporting scaffold must have been met (see requirements for supporting scaffold, paragraph 6), the girder supports slipped onto the adjusting frames and secured against lifting by locking clips. As described in paragraph 5.8, the roof sections must be fastened and lifted to their place of destination. For this purpose, a guide must be used. After the roof sections have been placed onto the girder supports, the roof girders are to be coupled using two welded half-couplers and two pre-assembled swivel couplers Erecting of the head struts If it becomes necessary for structural reasons to install head struts in the roof covering system (see material table, paragraph 9), such struts must be mounted on the roof girders shortly before erection. To this end lift the roof section to be placed by a crane and secure the same. Then, connect the head strut (three-chord girder) to the roof girder. For connection use a swivel coupler coupled upstream of a vertical tube or secure it with a second upstream coupler. For the distance of the head strut from the inner upright of the supporting scaffold see the drawing below. A rope should be provided at the head strut for easy pulling and mounting it after the roof section has been put in place. Couple the head struts to the supporting scaffold using both braces. Make sure that the roof overhang is the same at all roof trusses and on all sides. After the roof sections have been firmly mounted, the Keder sheetings must be fastened on the eave side at the assembled eave ledgers (see paragraph 5.7) using belts with latches. After all roof sections have been mounted this way, please close the empty sections created between the individual crane lifts Pulling in the Keder sheeting from the deck This version is used for roof covering systems of nominal widths 20.4 m to 23.2 m. In this case no longitudinal ledgers are needed in the empty sections. The Keder sheeting has to be tied with scaffold ropes laid out beforehand on the adjacent sections and pulled from the opposite roof side via an idler, arranged at the ridge, to the desired position and fastened there. In the eave area, the sheetings are to be fastened at the ledgers using belts with latches. This version is used for roof covering systems of nominal width starting at 23.2 m. 20 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

11 Erection Erection (1) (2) (3) (4) Keder rails for wall covering The Keder rail is installed by applying the Keder rail holder. To insert the Keder rail into the Keder rail holder, hold the fixed part of the holder and turn the rail in from the side (1). When the Keder rail locks into its final position (2), the moveable part of the holder is automatically closed and locked around the Keder rail (3). Keder rail and holder are friction-locked and positive-locked to the cotter by a stroke with a hammer (4). Thanks to the continuously variable adjustment of the Keder rail to the scaffolding, independent of position and number of Keder rail holders, the installation is possible at any time, even afterwards. Thanks to the stable construction of the Keder rail, holders are necessary only every 2m. This reduces the number of Keder rail holders by 1/3 and so a significant amount of installation time can be saved. Aluminium Keder rail with tilting pin for fastening eave ledgers can be used to fasten the roof sheet even when Keder rails are used for eaves. The wall sheet can be fastened by inserting an eave ledger link into the upper opening of the Keder rail and by then using another eave ledger Erecting the roof sections with mobile weather shelters Girder supports are to be mounted on the necessary roof girders. Please ensure that both girder supports are fastened at the same location of the relevant roof girder side. The girder supports are coupled using two welded halfcouplers and two pre-assembled swivel couplers. Then, push the triangular columns into the girder support and secure the same against lifting by locking the clips. After the castors have been pushed into the triangular columns, the first two pre-assembled roof girders can be erected (usually by crane) and put onto an assembly frame of scaffold components or Roof girders are to be arranged at grid distance parallel to each other. As the next step, the wall bracing is to be provided at the triangular columns. For this purpose, please connect the lower tube sockets with the upper horizontal tube using two longitudinal ledgers and one diagonal ledger. Now, the roof bracings must be provided according to item 5.4. Since the standing height of the workers will exceed 2.0 m, this work must be carried out from a tower scaffold. The roof bracings must always be mounted starting from the eave upwards to the ridge and from there downwards to the eave. Thus, twisting and distortion of the roof girders will be avoided. After all roof sections have been pre-assembled this way, the castors (with pre-assembled half-coupler) should be connected with each other by steel tubes to ensure tracking stability of the structure Anchoring the mobile shelters Before the roof sheeting is put in place on the mobile weather shelter, the latter must be anchored! Mobile shelters must always be anchored in the ground at every upright. If it is not possible to anchor each individual upright, the distance of the anchoring points can be changed by providing an auxiliary construction. For this purpose, connect the triangular columns with lattice girders in longitudinal direction and do the anchoring to the lattice girders. One should keep in mind that every upright must be protected against lifting by 850 kg (closed on all sides, max. span width, in the worst case, i.e. three sides closed, approx kg) and by approx kg tension and pressure (closed on all sides, max. span width; in the worst case approx kg) against horizontal travel. Due to the low dead weight of the structure, mobile weather shelters can only be moved under almost windless conditions. As soon as the final position has been reached the mobile shelter has to be anchored immediately. 22 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

13 Requirements to the supporting scaffold Requirements to the supporting scaffold 6.2. Explanatory notes 6.5. Scaffold bracing of longitudinal wall The WACO Roof Covering System 600 can be mounted on scaffoldings having grid sizes of 2.50 m and 2.57 m. It is suitable for assembly frame widths of or and or According to structural analysis, the weather protection roof can be placed on a maximum of three scaffold layers protruding the last anchoring (see general technical data of scaffold bracing). It is always necessary to provide at the topmost assembly frame a walkway of scaffold brackets or Keder brackets at deck level Anchoring the longitudinal wall The distance between the point of roof support and the topmost anchor tie must be the same as that from the topmost point of anchorage to the next lower one. With a projection of four metres, for example, the lower anchor tie must be placed four meters below the topmost anchor tie (also see drawing paragraph 6.1.). As a rule, all uprights have to be anchored. The topmost possible anchor tie must be a triangular tie because of the high forces to be absorbed. The lower anchor tie in relation to the cantilever needs simple anchoring only. The anchoring as described above only refers to the facade scaffolding in connection with the weather protection roof. The façade scaffolding has to be anchored as specified by the scaffold approval concerned. Make sure that anchoring is carried out in a careful manner and the ground and the structure are checked for stability and compatibility Anchoring the gable wall Gable walls have to be anchored at the same level. Here too, the top anchor tie must be a triangular tie. The lower anchor tie is of standard design. The inner uprights of the scaffolding frame must be braced by an additional tube 48.3 mm according to DIN EN 39. The tube must be coupled in the quarter points of the scaffolding frame. The assembly frames in the area of the cantilever (lower anchor up to roof support) are braced crosswise by two cross diagonal braces. The assembly frames in the area below the head strut connection are braced crosswise by four diagonal braces. The scaffold is braced in longitudinal direction in a crosswise manner by one diagonal brace each at the inner upright and outer upright. The arrangement of the braced sections is the same as that in the roof. If a bracing of the assembly frame as described above is not possible in this area because of construction work, lattice girders have to be coupled vertically to the outer uprights of the assembly frames along the cantilever. Keep in mind that these are steel lattice girders. The open girder chord must be braced every 2.0 m in transverse direction or connected by scaffold tubes above and below the scaffold floors with the assembly frames (to both uprights) Scaffold bracing of gable wall The inner uprights of the scaffolding frame must be braced by an additional tube 48.3 x 3.2 steel 235. The tube has to be coupled in the quarter points of the scaffolding frame. The assembly frames in the cantilever area (lower tie up to roof support) are braced in a crosswise manner by two diagonal braces. If a bracing of the assembly frame as described above is not possible, the lattice girders are coupled vertically with the outer uprights of the assembly frames along the cantilever. Please keep in mind that these are steel lattice girders. The open girder chord must be braced every 2.0 m in transverse direction. 26 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem

14 Span Span 7.1. Stationary weather protection roof on working scaffolds To determine the required span, please observe the following: Projections of buildings (bay windows, eaves) Scaffold used (0.73 m or 1.09 m) Type of wall sheeting (standard or Keder technology) nominal width 10 m nominal width 11.5 m The required span consists of: Kind of wall sheeting + scaffold width + wall distance + building width + wall distance + scaffold width + type of wall sheeting (with Keder rails approx. 20 cm) nominal width 13 m nominal width 14.5 m nominal width 16 m nominal width 17.5 m nominal width 19 m The possible spans of the WACO Roof Covering System 600 can be found in the material tables and the figure below. The span of the roof must be at least 20 cm larger than the span obtained from the above formula. Since this roofing system can be placed steplessly onto the supporting frame, various roof overhangs are possible. 28 Instructions for Erection and Use WACO Roof Covering System 600 Instructions for Erection and Use WACO Überdachungssystem
