Method for laying reinforced meshes of cast-in-situ concrete floors

Abstract

The invention relates to a method for laying reinforced meshes of cast-in-situ concrete floors. The method is characterized by comprising steps of 1), designing and welding the reinforced meshes; 2), laying the reinforced meshes of bottom layers of the floors; 3), laying the reinforced meshes of surface layers of the floors; 4), arranging plastic cards or mortar spacers on the reinforced meshes of the bottom layers and arranging horse-shaped stools on the reinforced meshes of the surface layers at intervals of 600-900 mm. The plastic cards or mortar spacers are equivalent to the thicknesses of the protective layers. The method has the advantages that reinforcing steel bars of the concrete floors can be constructed by the aid of the method, accordingly, straight stressed reinforcing steel bars in longitudinal and transverse directions can be guaranteed, grids of the reinforcing steel bars have uniform sizes, and the meshes, which are formed by means of welding, of the reinforcing steel bars are good in integrity, high in stiffness and difficult to deform and are difficult to locally bend, deform and deviate even under the effect of external force in concrete pouring construction procedures; the concrete protective layers, which are formed by means of pouring, of the reinforcing steel bars of the floors have uniform thicknesses, and accordingly the crack resistance of the floors can be improved; a large quantity of labor can be saved, the production efficiency can be improved, and good economical effects can be realized.

[0002] At present, the traditional pavement method of cast-in-place concrete floor reinforcement is to process the reinforcement into straight strips on site according to the structural design drawings, and then cut and manufacture them. Workers place the processed reinforcement one by one according to the layout and spacing of the structural design drawings. Put it in place and then tie it into shape. The traditional method is used to pave the floor reinforcement. The steel reinforcement in the vertical and horizontal directions of the floor reinforcement mesh bound by the worker is not very straight, and the size of the reinforcement mesh is not very uniform, especially the smaller diameter. It is more difficult to control the steel bars. When the workers are binding the steel bars on the floor, there are interval jumps and missed bindings at the intersections of the steel grids. The integrity of the steel mesh sheets is poor and the rigidity is small. Local deformation and misalignment are prone to occur, resulting in uneven thickness of the reinforced concrete protective layer of the floor, and poor crack resistance of the floor. Low production efficiency and poor economic effect
