Floor board cast-in-situ method

Abstract

The invention discloses a floor board cast-in-situ method, which is characterized by firstly acquiring a prefabricated member, wherein the prefabricated member comprises a flat soleplate part and at least one bead which is arranged above the soleplate part and arranged in the length direction, a reinforcing steel bar is embedded inside the prefabricated piece along the length direction, two ends of the reinforcing steel bar are provided with a reserved section extending out of the prefabricated piece, and the bead is provided with a plurality of through holes at intervals in the length direction which penetrate through the bead along the width direction; and during the pouring construction, the soleplate parts of a plurality of prefabricated members are downwards connected with each other and placed among leveled vertical walls, a side template flange is respectively installed on the periphery of the prefabricated member, and secondary concrete is poured inside a side template, so that the prefabricated members are connected into a whole to form a floor board structure. The floor board cast-in-situ method is used for producing a building floor board in building construction. Due to the adoption of the method, the complex die-block supporting work can be avoided, the construction cost can be reduced, and the construction time can be reduced; and meanwhile, the method also has the advantages that the integral strength of the building can be guaranteed, and the safety of the building can be improved.

Description

technical field [0001] The invention relates to a building construction method, in particular to a floor floor cast-in-place method. Background technique [0002] At present, the method of cast-in-place formwork is generally used in the construction of buildings in China. When the formwork is cast-in-place, it is necessary to use formwork to support on-site to form a model, and then pour concrete into the model for curing and forming. [0003] This mold-in-place method can embed criss-cross steel bars during pouring, which maintains the integrity of the building and improves the overall strength of the building. However, the cast-in-place method is a complex and changeable large-scale process when the formwork is poured. It requires a large number of molds, complex formwork, and takes a long time for construction and pouring. The disadvantage of long time. At the same time, this mold-in-place method makes it difficult to accurately locate and pre-tension the steel bars use...

AI Technical Summary

Problems solved by technology

However, when the existing prefabricated panels are laid and installed, they cannot form a criss-cross and networked steel structure, which greatly reduces the overall strength of the building, so it has been abandoned in modern building construction.
