2 Strengthening India Going Goba Jinda Stee and Power Limited (JSPL) is one of India's major stee producers with a significant presence in sectors ike Stee, Mining, Power Generation, Petroeum, Infrastructure, Cement and Info-soution. From the widest fat product to a whoe range of ong products, JSPL today sports a product portfoio that caters to varied needs in the stee market. The company aso has the distinction of producing the word's ongest 121 meter rais and introducing parae fange beams in India. Recenty JSPL has arised with revoutionary and innovative technique to eiminate the outdated conventiona fooring system with suspended concrete fooring system known as Jinda Speedfoor. The manufacturing faciity for Jinda Speedfoor is ocated 30kms away from the heart of Raigarh City, Chattisgarh at O.P. Jinda Knowedge Park, Punjipatra. With an annua turnover US $ 3.5 biion, JPSL has committed investments exceeding US $ 30 biion in the future and has severa business initiatives running simutaneousy across India, South-East Asia, Africa, South America, Austraia and Georgia.

3 Our name says it a. SPEEDFLOOR, the unique suspended concrete fooring system, is an innovation in the buiding industry. So quick and easy to insta, SPEEDFLOOR is a ightweight, cost-effective system that's perfect for muti-storey buidings and carparks. Whether it's one storey or fifteen, the recipe is very simpe. take sufficient quantity of SPEEDFLOOR, add structura stee or concrete supports, mix concrete and pourat the heart of the system is a speciay roformed, gavanised stee joist that offers a the benefits of an open-webbed truss system at a more enough to be man- handed into pace, reducing cranaage costs. Services are easiy accommodated through the joists which are deivered to the site ready to insta. SPEEDFLOOR The perfecty simpe, simpy perfect soution to muti-storey construction. Stee used for making JOIST is of Grade 350 which has a minimum yied stress of 350MPa and a minimum tensie stress of 380Mpa as we a minimum coating of Z275 is maintained. Generay Speedfoor uses a 75mm or 90mm topping in comparison to the other conventiona RCC fooring systems. The joist weights per inear metre are as foows: a. 200mm deep = 9.41 kg/m b. 250mm deep = kg/m c. 300mm deep = kg/m d. 350mm deep = kg/m e. mm deep = kg/m Sab thickness SUPPORT 75 typ 10 Top fange typ cearance M16 8.8/s Shoe Lockbar sot 25 Mpg Concrete for 75 or 90 sab 665 Mesh Service hoe varies* 75 or 90 Bottom fange varies CLEAR DISTANCE BETWEEN SUPPORTS (ORDER LENGTH) No propping is required. The joists are ightweight, requiring ess craneage than other concrete fooring systems. Services can be passed through the hoes pre-punched in the joist The bottom of the joist can support a suspended fire rated ceiing directy fixed to the joist. The ockbars and pywood sheets are reusabe. Easy to insta 4The pywood is introduced from the top and is hed in position by the cam action of the ockbars. A working patform from which the rest of the pywood can be aid is quicky progressed down the buiding 2Lockbars, which wi support the pywood shuttering, are sid into the sots punched in the top section of the joist and by engaging the notches at both ends of the ock bar, the exact spacing of the joist is secure. 5The mesh is aid out and tied into pace. No stoos are required as it is hed off the deck by the top section of the joist, which becomes embedded in the concrete and wi gain composite action once the concrete is cured. 1The individuay marked, ightweight roformed stee joists are easiy ifted into pace on the support medium. 3Lockbars are paced approximatey 300mm apart to give the pywood good support. 6The finished foor after the ock bars and pywood are removed reveas the concrete soffit and exposed joist where services can be passed through prepunched hoes. The bottom of the joist can support a suspended fire rated ceiing directy fixed to the joist.

4 Design Parameters The concrete sab topping has a compressive strength of 32MPa after 28 days. Speed foor system can meet fire rating requirement set out in buiding codes through various means such as fire resistant painting of joists, fire rated ceiing.
