Embodiment 1

[0043] 1. The preparation work before filling the inner mold in the board

[0044] (1) Support plate bottom mold and side mold

[0045] Support the floor slab bottom form and beam side form according to the requirements of the drawings.

[0046] (2) Stake out on the template

[0047] According to the construction lofting drawing, accurately mark the exact position of each filling inner mold and solid rib on the template.

[0048] (3) Binding the steel bars at the bottom of the plate and installing pipelines

[0049] According to the requirements of the design drawings, bind the steel bars at the bottom of the slab and install the pipelines.

[0050] 2. Fill the inner mold laying

[0051] Install the inner filling mold assembly unit accurately at the design position. If it conflicts with the pipeline, it needs to slot and plug the inner filling mold. Filling internal mold construction requires pipeline laying: where there is a filling internal mold, the pipeline should be laid horizontally...

Abstract

The invention discloses an anti-floating construction method for a cast-in-place concrete hollow floor sectional type combined device. The method comprises the following steps of A preparation work before laying of a filling inner mold in a plate, B laying of the filling inner mold, C laying of reinforcing steel bars on a plate face, D anti-floating treatment of the filling inner mold, E cleaning of a construction operation face and F removal of a formwork. An anti-floating pull rod is adopted for replacing an iron wire in the prior art, it can be guaranteed that the bottom of a concrete floor slab is smooth, and no residues are left to influence later decoration. In the concrete unloading process, the formwork is flatly laid on an unloading reinforcement mesh for buffering, and concrete is poured in the single direction of the longitudinal axis of the filling inner mold in a laying mode through manpower.

Description

Technical field [0001] The invention relates to an anti-floating construction method of a segmented combined device for cast-in-place concrete hollow floors, which belongs to the technical field of building construction. Background technique [0002] The construction technology of cast-in-place concrete hollow floor is a new technology developed in China in recent years. Compared with solid concrete floor, it has the advantages of light weight, large span, good rigidity, good sound insulation and heat insulation, and lower cost. It is especially suitable For construction projects with large bays and large span requirements. Due to the light weight and large quantity of cast-in-place concrete, the buoyancy effect will be produced during concrete pouring, which can not be solved well. The light one will cause the partial floor elevation to be super high, reducing the thickness of the decoration method, and the heavy one will cause a large area to float up and cause quality acciden...
