Abstract
An efficient construction method of cast-in-situ hollow floor relates to a construction method of the cast-in-situ hollow floor. The invention aims to solve problem that the damage ratio in producing, conveying and construction process is high and a filler element on a molding plate is not easy to position by a thin wall hollow box that mainly adopts cement material. The invention is provided with a plurality of ceilings without gap at upper side of a temporary supporting beam; a gas-entrapping block of magnestite material or an assembling hollow box placing the magnestite material is placed on the ceiling as the molding plate. The gas-entrapping block of magnestite material or an assembling hollow box placing the magnestite material matches a concave and convex line of the ceiling. The construction method of the invention places the gas-entrapping block of magnestite material or the assembling hollow box placing the magnestite material in site, which implements a batch of works in a large scale. The temporary molding plate for the exchange in site is saved and the filler element is easy to fix on the molding plate. The sunshade is not need to be plastered after detached. Self-weight of the floor is light, which saves a lot of reinforcing steel bar and concrete and other construction materials.
Description
Technical field
The present invention relates to a kind of job practices of cast-in-situ hollow floor plate.
Background technology
For building large span floor, reducing material usage and construction costs, many in recent years large span floors all adopt the structure of the cast-in-situ hollow floor plate of dark close rib, to form very high hollow rate.The hollow floor slab structure of this class all requires the hollow unit of in advance prefabricated formed structure hollow cavity in a large number.This hollow unit comprises lightweight filler and thin-walled hollow box.Should satisfy the technical requirements that the permanent position is arranged and can bear the working load on hollow unit at construction hollow core member.There is the problem that unit weight is big, cost is high all having very big defective aspect manufacturing, the installation in existing hollow unit such as the haydite piece in the lightweight filler, cement aerated blocks, perlite block or benzene plate.And the thin-walled hollow box adopts the cement material manufacturing more, processes one by one with particular manufacturing craft in factory, because of the thin-walled hollow box is difficult for the rapid demoulding, so the mould consumption is a lot.Also make by hand by the workman because of the thin-walled hollow box, labour intensity is big, inefficiency.Because the thin-walled hollow box is a cement products, breakage rate is higher in production, carrying and work progress.So the thin-walled hollow box of the cement that generally adopts now making can not well satisfy the needs of engineering construction, and the application of the cast-in-situ hollow floor plate of dark close rib is restricted.And the lightweight filler economic and technical norms are relatively poor in the existing hollow unit, are difficult for the location on template.
Summary of the invention
The objective of the invention is to adopt the cement material manufacturing more, in factory, process one by one, because of the thin-walled hollow box is difficult for the rapid demoulding, so the mould consumption is a lot of with particular manufacturing craft for solving the thin-walled hollow box.Also make by hand by the workman because of the thin-walled hollow box, labour intensity is big, inefficiency.Because the thin-walled hollow box is a cement products, breakage rate is higher in production, carrying and work progress, the lightweight filler economic and technical norms are relatively poor in the existing hollow unit, are difficult for fixing problem on template, and a kind of high efficiency construction method of cast-in-situ hollow floor plate now is provided.Job practices of the present invention realizes according to the following steps: one, set up interim brace summer 51; Two, make ceiling 41: have decoration functions below the ceiling 41, be provided with concavo-convex line 42 above the ceiling 41, the ceiling 41 of concavo-convex line 42 peripheries is provided with suspension hook 43; Three, the gapless ceiling 41 that is paved with on interim brace summer 51; Four, lay the aerated blocks 21 of magnesite material on the double ceiling 41 of doing template or lay the hollow box 31 of assembly type of magnesite material, the aerated blocks 21 of magnesite material or the hollow box 31 of the assembly type of magnesite material all match with the concavo-convex line 42 of ceiling 41; Five, be lowered to reinforcing bar, assembling reinforcement in the space between the hollow box 31 of assembly type of the aerated blocks 21 of magnesite material or magnesite material; Six, fluid concrete gets final product.Job practices of the present invention is the hollow box of assembly type of laying the magnesite material aerated blocks at the scene or laying magnesite material, can realize extensive mass operation, because the magnesite material good toughness, its breakage rate is almost nil in production, carrying and work progress.For the application of cast-in-situ hollow floor plate provides wide space.Save the temporary formwork that turnover is used at the construction field (site), aerated blocks or hollow box are very easily fixed on template, and ceiling need not be plastered after the form removal.The deadweight of floor is very light, can save constructional materialss such as a large amount of reinforcing bars and concrete, helps the job site and realizes civilized construction.
