6 Cassette Roof LAYHER CASSETTE ROOF // FOR WEATHERPROOFING AND TEMPORARY HALLS LOW-COST, LABOUR-SAVING ROOFING. Layher cassette roofs have established themselves as a firm favourite at construction sites for conversion, renovation and restoration. The structure itself and all the equipment is protected during the conversion or roof repair and normal business operations can continue under a secure roof. If weatherproofing is the aim then there are many reasons to choose the Layher cassette roof system. Economical thanks to top-class technology A sophisticated, proven construction consisting of high-quality components, specially equipped for recurrent, changing assembly and dismantling operations. supporting structure using a crane. The roof cassettes for the intermediate bays are inserted into the channel section and locked in place with clamping plates and wedges. That s all there is to it! No tensioning or tying is required. The cassettes act as bracing elements. Only every second bay is assembled as a so-called truss bay, and there are no doubled roof trusses. This represents an additional saving of material and, consequently, also of money and assembly time. Economical modular system Variable roof areas are possible thanks to the well-conceived section lengths of the roof trusses and the U-shaped top chord. Long, useful service life The Layher cassette roof is almost indestructible. Its practical design coupled with the chosen materials are key reasons making it an investment that will retain its value over many years. The use of cassette roof girders ensures rapid assembly. The roof trusses are assembled astonishingly quickly at ground level, then mounted on the Vast spans Depending on the static system and the load, it is possible to create roof structures with spans of more than 40 m. 6

7 Easy to open for material supply To permit material supply to the site, the Layher cassette roof can be opened at any location by simply removing one or more roof cassettes. No crane is needed. System-independent The Layher cassette roof does not require any specific substructure. This means that no unwanted additional investments are required. The Layher cassette roof can be mounted easily on almost any scaffolding or other suitable substructure. A structural analysis for spans of up to 7. m exists for the roof structure. It is necessary to check the stability of the supporting structure (e.g. scaffolding) and the roof structure. This cassette roof is a non-insulated, rainproof covering under which condensation may form and drip depending on the outside weather. The connections between the cassettes are not sealed and rainwater may penetrate due to unfavourable wind conditions. We cannot therefore accept any liability for damage to the covered structure. However, additional sealing options exist. Totalweatherproofing Rainwater is excluded correctly thanks to the over-lapping, shaped roof surface elements. This is a basic requirement for any weatherproofing roof. Notes on construction and use When assembling and using the roof, it is essential to observe the applicable regulations and the manufacturer s assembly instructions. Personal safety apparatus (PSA) for protection against falls must be used. 7

8 Roof beam system as truss elements The system for large spans and rapid assembly for everyday use Roof beam system as truss elements Truss elements These one metre high roof beams are the elements that support the cassette roof (U-shaped top chord for the insertion of the roof cassettes, tubular bottom chord and posts of diameter 48.3 mm). The ridge support is intended for the construction of double-pitch roofs with a roof angle of approximately. The roof beams or ridge supports are connected to one another at the bottom chord with 30 x 50 mm bolts 3 and 4 mm safety clips 4. At the top chord, it is possible to use either two M4 x 80 bolts with nuts or 4 x 77 mm bolts with.8 mm safety clips 5. Depending on the structural analysis, some construction variants may require the use of a third 4 x 07 mm bolt and.8 mm safety clip 6 at the top chord. 3 A truss bay consisting of a pair of roof trusses connected to beam stiffeners 8 is pre-assembled at ground level and the roof cassettes are mounted on it and wedged in place. A crane is used to place the pre-mounted truss bays on the scaffolding at intervals of.57 m, while the unoccupied intermediate bays are reinforced with tubular stiffeners 9 and then closed using roof cassettes.

10 Roof girder system as truss elements Bracing elements In the case of high levels of snow and/or large spans, it is necessary to install a tie. The end pieces of the ties are connected to the last bottom chord joint using 30 x 64 mm bolts 3 (Ref. No ) and extended by one or more tie spacers. The tie elements are joined to one another using lattice beam connectors 5 (Ref. No ) and are suspended using scaffolding tubes and couplers. When mounting ties, it is necessary to install a.0 m long roof girder as the external roof girder. Lattice beam connectors (Ref. No ) are used to connect the tie end pieces or spacers. Each of these requires either two M4 x 65 bolts 6 with nuts or four 4 x 77 mm bolts with.8 mm safety clips 7. Roof girder system as truss elements Tie connection 7 Roof cassette elements Roof cassettes with corrugated sheet The roof cassettes 8 consist of a robust, hot-dip galvanized steel frame with shaped steel sheets and form the rainproof, walk-on roof covering of the cassette roof. The cassettes improve the horizontal rigidity of the roof. They can be supplied in lengths of.0 m and.0 m. The roof cassettes are inserted in the channel section of the top chord and are secured positively and nonpositively using wedges and clamping plates. In this case, the clamping plate acts as a force-distributing base while the specially shaped wedge prevents slippage. Roof cassette elements 8 The.0 m-long cassette is also available with an access hatch 9 to provide you with a safe, easy way onto the roof. 9 0

20 Keder Roof LAYHER KEDER ROOF The Layher Keder Roof is a lightweight weather protection roof (manufactured from aluminium) which can be mounted without a crane up to approximately 8 m. Used in conjunction with Keder rails for wall cladding, it means that the entire construction can be designed to form a lightweight hall. It has many areas of application, ranging from the roofingduringthe addition of storeys and the implementation of timber roofs and coverings, weather protection for new structures or refurbishment work on motorways and over bridges through to numerous applications for events and normal work. The distance between trusses is.57 m or.07 m for SpeedyScaf or Allround Scaffolding as the supporting structure. It is possible to extend the construction to a height of m without additional stiffeners. Larger spans are possible but require additional construction measures. A special Keder Roof support provides the highest possible level of versatility for all assembly variants and compensates for any tolerances due to the underlying surface. The roof surface consists of high-quality PVC tarpaulins guided using keder rails and forms a watertight covering. It is a non-insulated, rainproof covering under which condensation may form and drip uncontrolled, depending on the weather. Snow loads of up to 0.5 kn/m² are permitted. beyond this value, the snow must be cleared. The construction is designed in such a way that only every fifth bay has to be fully braced with wind braces. Fewer Keder roof ledgers are thus required in the intermediate bays. Insert connections or snap-on claws at the individual components ensure very short assembly times, while the lightweight aluminium material (approximately 8 kg/m² for the aluminium roof structure) means that no heavy physical work is required: everything is designed to permit simple, clear, efficient assembly. The component dimensions, designed with practical applications in mind, mean that no valuable storage space is occupied unnecessarily. The Layher Keder Roof is particularly suitable for meeting short-term requirements. Thanks to its versatile system technology and short assembly times, it is also extremely economical and a very attractive overall solution for lightweight assemblies. 0

22 Keder Roof elements Keder Roof Roof trusses Depending on the span and roof type, the roof trusses are assembled using.5 m and 3.0 m lightweight aluminium lattice beams together with an eaves and ridge section. The top chord of the beams is shaped as a keder rail in order to accommodate the tarpaulin covering. Spigots at the beams form a stable connection between the beams and the individual joins are secured without the use of screws by means of bolts and safety clips. Keder Roof elements Lattice beam with fixed, screw-in spigots. The top chord is a keder section designed to accommodate the tarpaulins. Mono-pitch roof lattice beam with spigots on both sides. Only required as a spacer on mono-pitch roofs. 3 The ridge section 3 (roof pitch 0 ) guides the entire keder tarpaulin over the ridge and ensures that water can run off unobstructed. The eaves section 4 at the end of the truss guides the keder tarpaulin via the curved top chord towards the wall or closes the construction as required. The stiffener 5 ensures the lateral stability of the trusses. Up to external truss dimensions of 5.6 m, it is only necessary to brace every fifth truss bay. Snap-on claws ensure extremely fast assembly at the girders tube connectors. 4 5 The diagonal braces 6 help stabilize the construction and take up wind loads at the truss bays. The Keder Roof ledger 7 braces the individual trusses in the intermediate bays. The steel support 8 with its three rotary axes makes it possible to construct mono-pitch and double-pitch roofs. Asymmetrical truss shapes and eaves projecting on one side can be constructed without any additional effort and tolerances in the substructure compensated for. Two half-couplers secure the trusses to the bottom chord. Possible pitches for the mono-pitch roof variant: Support 0.73 m: 0 5 Support.09 m: To prevent water pooling, the roof angle should be not less than

30 Keder Roof XL LAYHER KEDER ROOF XL Layher s Keder Roof has long proven itself a great success. but with the Keder Roof XL, Layher is setting new standards for temporary roofing over construction sites or stages. Where roofs are often limited to a 0 metre span for structural strength reasons, the Keder Roof XL comes into its own. Taking into account requirements to cope with local weather conditions, it can be built with a span of up to 40 metres! The Layher Keder Roof XL is based on Aluminium Lattice beams 750 with integrated Keder section in the top chord. The Layher Keder Roof has many areas of application, ranging from the roofingduringtheadditionofstoreys and the repair of timber roofs and coverings, weather protection for new structures, refurbishment work on motorways and over bridges, and numerous applications for events and normal work. THE benefits TO YOU: Roof widths up to 40 m. High snow loads (up to about.0 kn/m²) with medium spans. f aster and easier fitting of Keder tarpaulins. Compatible with all Layher scaffolding systems. Material and load bearing-capactity tables are available to ease the planning. Double-pitch, mono-pitch and polygonal barrel roofs are possible. 30

38 Mobile Roofs MOBILE ROOFS // THE ECONOMICAL EXPANSION OF LAYHER ROOF SYSTEMS Whether on a rapidly advancing construction site or under cramped conditions, you can get Layher s protective roofs rolling to where the action is with only a few extra components. flexibility and economy to the highest degree with mobile roofs from Layher. THE benefits TO YOU: The mobile roof can be moved section by section to match the construction progress and only covers the area being worked on at the time. That makes it unnecessary to build a protective roof over the entire site. Slight variations in the alignment of the rails can be compensated with a transverse adjustment on the trolley. The bay width of the roof is independent from the bay widths of the support scaffolding giving you much more flexibility when assembling. for example, openings can be achieved by simply sliding the roof apart. Also overlapping roofs are possible. The individual bays of the roof can be set down at a certain location with the crane, joined together, and then moved to its final destination. 38

No Quality management certified according to ISO 900:008 by German TÜV-CERT // THE EASY AND quick ROOfING for WORKING PLATfORMS Of façade SCAffOLDING THE TEMPORARY INTERMEDIATE ROOF B Layher has devised an efficient solution for putting a roof over the work area, to permit work on scaffolding uninterrupted by the effects of the weather its new temporary intermediate roof. Attached in a very short time, it provides effective protection against rain and snow not only for professionals such as bricklayers, painters and plasterers, but also for newly laid brickwork, thermal insulation or fresh paintwork. The new temporary intermediate roof comprises PVC roof tarpaulins that can be quickly and easily attached to Layher s SpeedyScaf and Allround systems by just one person using a few additional components, and also removed or repositioned in the same way. Thanks to its time-saving construction, it can also be fitted at short notice if required. LAYHER SPEEDYSCAF SYSTEM CATALOGUE For further details see SpeedyScaf catalogue. 39

40 Mobile Roofs elements Mobile Roofs Keder roof or Keder roof XL can easily be made mobile with a few additional parts. This can then be moved section by section to keep pace with construction progress, so it s no longer essential to provide a roof over the entire surface, or alternatively to dismantle and rebuild a roof for each stage of building work. The mobile roofs fit onto all scaffolding systems and are also flexible and economical to use. The rails don t need to be laid exactly parallel, since the trolley permits equalization in the transverse direction. The support scaffolding bay widths are completely independent of the mobile roof, allowing the scaffolding to be built with wider bays. besides faster assembly, the supporting structure also permits material savings. The assembly of the roofs themselves is also simple and quick: the roof bays can for example be assembled at a readily accessible point at the gable end of the building, from an auxiliary scaffolding or using a crane. One bay at a time is assembled, then moved, and has the next bay attached to it. Mobile Roofs elements 3 4a 4b The overlap bracket 5 can be used, when de roof binders are mobile. If separate segments of the roof must be put togehter, there will be a gap in the roof. by using the overlap bracket combined with Aluminium keder rails 3000 and roof tarpaulins 0,46 m wide, these gaps can be closed. 3 40

42 Protect System LAYHER PROTECT SYSTEM // THE LOW-COST, LABOUR-SAVING ENCLOSURE FOR ENVIRONMENT, NOISE AND WEATHER PROTECTION With the Protect System, Layher can supply a cassette enclosure system which is compatible with the Layher Allround scaffolding and SpeedyScaf systems and which meets requirements concerning environmental protection and insulation from noise and weather. It is an exceptionally economical solution which boasts Layher s renowned quality: Only a small number of individual parts, designed for frequent, changing applications. To provide noise protection, it is possible to equip wall cassettes (sound insulation value: 0 db) as sound insulation cassettes (sound insulation value: 6 db) or use cassettes providing a higher level of sound insulation. Light cassettes permit work in daylight conditions within the enclosure. Cassette elements exist for external and internal corners. Rapid, easy assembly in a simple, logical sequence. The cassettes are designed for Layher axis dimensions (max. width: 3.07 m) and, with a height of.0 m, are very simple to assemble and move into the scaffolding. A specially developed connection rail is used to establish a connection with the existing building or the ground. Practical solutions for horizontal and vertical dimension compensation are available. The surrounding rubber seal makes the cassette elements almost dustproof (façade coating), vacuum-compatible (removal of asbestos), waterproof (sandblasting work). Electrostatically inert and therefore easy to clean. Scaffolding with bay lengths of.57 m can be clad up to a height of 90 m (in the case of 3.07 bay lengths, a height of 50 m is possible). The anchoring layout corresponds to that of scaffolding which is clad with tarpaulins. 4

43 Access elements compatible with system and individual requirements are available. Layher Protect System: a system which meets all environmental and safety requirements and prevents all risks. The individual components of the Protect System can only be supplied ex works from Eibensbach. Metric bay lengths can be ordered subject to delivery times. 43

44 Protect System elements Cassette elements Frames made from aluminium sections with galvanized sheet steel inserts. A surrounding rubber seal provides a clean, precise connection to neighbouring elements. Protect System elements The wall cassettes can be converted to form noise isolation elements. The sound insulation value is 0 db without and 6 db with a sound-insulating mat (as measured at the fraunhofer Institute in Stuttgart). This means the noise emission is reduced by more than 75 %. On request, it is also possible to supply special wall cassette variants with enhanced sound isolation properties in accordance with the Supplementary Technical Requirements and Guidelines for Highway Noise Insulation Walls ZTV-Lsw 88:988 and the evaluation in accordance with Db guideline , section. A test report concerning the airborne sound insulation of scaffolding coverings issued by the Fraunhofer Institute for building Mechanics in accordance with ZTV-Lsw 88:988 or Db guideline is available. Thanks to the use of light cassettes, it is possible to work in daylight conditions behind the enclosure. In this case, a translucent plastic web plate replaces the steel plate in the aluminium section frame. Connection rails 3 close the enclosure at the ground or building. These are clamped to the cassettes and make it possible to pull a Keder tarpaulin into the built-in Keder groove. Alternatively, a sheet or board can be adapted for use with the wooden strip intended for this purpose. Connection rails also permit the clean, close-fitting connection of fitted bays. Internal and external corners are formed using corner cassettes 4, while the corresponding connection rails 3, which are inserted in the holder, permit a close-fitting connection to the neighbouring cassettes and close the system both visually and in functional terms Corner elements with other angles upon request 44
