Suspended concrete floor slab design
Suspended concrete floor slab design- The mesh reinforcement in the slab is placed in the top with 1" covers The slab is constructed on well compacted granular fill, crushed stone or marl Figure B10 Alternative Floor Slab Detail The suspended reinforced concrete slab is tied into the external capping beam at floor level The top (steel) reinforcement is importantAs with particleboard flooring (see floors), it provided a flat level surface on which to construct and erect wall frames Concrete slab floor construction was often used for internal garages or lower levels of split level houses, with suspended floors used for other parts of the house Construction details Excavation
Selection of floor system Actual floor systems in buildings come in all sizes, shapes, and forms There are so many variables to any floor system such as different spans, offset spans, cantilevers, and the extent of continuity, the effects of beams, columns and walls on the slab system, etc that it is difficult to cover all situations in a limited series of chartsNo allowance has been made for the heaping of concrete during the casting of the slab Super Imposed Live Load Loading used are estimations of those regularly required for suspended floor systems 15kPa for residential, 25kPa for carparks/domestic balcony, 30kPa for office/commercial spaces and 50kPa for storage facilitiesGround floors Ground bearing solid concrete floors Guidance Diagram 9 Typical section through a ground bearing solid concrete floor and foundation Guidance Table 5 Examples of insulation for ground bearing floor slabs Suspended reinforced insitu concrete ground floor slab
Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building Concrete floor systems are designed to span in either one direction (oneway) or both directions (twoway) of a structural bayOnly 6"8" concrete topping required Using a composite steel and concrete design the floor slab can be thinner than conventional residential suspended slab systems This results in a cost savings in concrete of 2550%Ground bearing floor insulation below slab Ground bearing floor insulation above slab Influence of trees and clay Ground bearing slabs should not be used in ground conditions where heave can occur or where the foundation depth is greater than 15m Under these circumstances a suspended floor construction should be used Site preparation
First floor slabs is a well established company specialising in all concrete work specifically suspended in situ cast concrete structures Added rooms can use slab on ground or suspended slabs When renovating rooms with timber floors it is often possible to replace the timber with a concrete slab for added thermal mass and quietness underfootIf your ground floor timber floors have become infested with insect damage or dry rot you might choose to replace them with concrete floors However laying a concrete floor to replace your timber floors may not be the end of your troubles if you don't take care to treat the problem before you lay a concrete slab for your new floorOpenings in Concrete Floor Slabs BUILDINGS If you took an advanced concrete design course, you probably had a good introduction to the design of twoway slabsAlthough all multistory buildings require multiple small slab penetrations for routing of plumbing, fire protection piping, and ductwork between floors

Firstfloor slab thickness The normal thickness used for reinforced concrete slabs in South Africa is 170 mm for small slabs, 255 mm for slabs larger than 5m x 5m and 340 mm thick for longspan slabs forming part of a beam and carrying heavier loads The thickness of a slab will depend on the use and span of the slab Thickness of the slab is decided based on span to depth ratio specified in IS Minimum reinforcement is 012% for HYSD bars and 015% for mild steel bars The diameter of bar generally used in slabs are 6 mm, 8 mm, 10 mm, 12mm and 16mm The maximum diameter of bar used in slab should not exceed 1/8 of the total thickness of slab The Speedfloor Suspended Concrete Flooring is a unique, composite floor of steel and concrete that makes light work of pouring anything from single level, to multistoried structures There is no propping required Simply assemble the joists, add structural supports and you are ready to pour Load vs Span Calculator
A Line Drawing Of A Cross Section Of An Insulated Slab From The Suspended Concrete Floor Slab Detail, Slab On Grade Belongs To Concrete Floor Slabs Which Are Poured At 11 Best Steel Reinforcement Images Reinforced ConcretePile grids are normally in the range 3 x 3m to 5 x 5m, depending on the pile capacities and the intensity of loading It is assumed that the ground gives no support but simply acts as in situ formwork for the floor slab The design is the same as for suspended floors, using the approaches in BS 8110, now withdrawn and superceded by Eurocode 2These can be classed as either Suspended or Solid Solid floors are a lot more substantial and require the ground to be made up in layers of ground sub base, sand, compacted hard core, damp proof membrane, insulation and concrete
Here are my 5 most important things to check when inspecting a suspended concrete slab 1 Reinforcement at Maximum Moment At the most basic level, you are checking that the reinforcement is placed in the suspended slab in accordance with the design engineer's plans That is the minimum standard and you should be aiming for better than thatConcrete vs Timber Floors There are 2 types of floor construction used in the building industry today;E5MCFF30 Suspended InSitu Concrete Floor, Insulation Below Slab Build Up External Masonry Cavity Wall Masonry Outer Leaf (λ = 077) 100mm Aircrete Block Inner Leaf (λ = 019 W/mK) Full Fill Insulation 150mm Cast InSitu Suspended Slab

Suspended slabs are made of concrete and steel mesh, the same as a ground slab They are normally prefabricated offsite, and transported by truck Some slabs have hollow channels running through them these 'hollow core slabs' are used to help reduce weight, and also to allow cabling and piping to be run through the slab The American Concrete Institute Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensusbased standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concreteThis chapter gives guidance on meeting the Technical Requirements for suspended ground floors including those constructed from insitu concrete precast concrete timber joists 521 Compliance 522 Provision of information 523 Contaminants
Concrete Suspended Slabs Suspended slabs are upper floors of the ground that do not come into direct contact with the Earth They are often used to build floors for the upper stories of the house, but they can also be laid on top of the prebuilt walls to form a floor I'm designing a suspended concrete slab over a concrete basement walls for a house garage 24'X24' plan dimension Ideally I would like to avoid beams, but I know locally (Missouri) it has been done with one or two steel W shape beams to support the slabPour 3'' of concrete topping minimum onto the Precast Garage Floor Slope topping slab from 6'' to 3'' toward front of garage for proper drainage Place control joints directly above Precast Garage Floor keyway joints These may be tooled during concrete placement, or saw cut afterwards Additional waterstops, damproofing, and sealers can be used
Homespan Homespan is a revolutionary concrete flooring system consisting of flat precast concrete planks generally 600mm wide and 150mm deep Designed for residential use on both ground and first floor levels, it will carry domestic loading for spans up to 5m and is therefore cost effective Homespan slabs are manufactured to differing lengths
