Construction method of cast-in-place concrete composite floor slab

Abstract

The invention relates to a construction method of a cast-in-place concrete composite floor slab. A concrete composite floor slab forming device is adopted and comprises a bottom rack, a placing mechanism and a feeding mechanism. The construction method can solve the following problems that in the traditional cast-in-place concrete composite floor slab preparing and forming process, one cast-in-place concrete composite floor slab preparing and forming device can only produce cast-in-place concrete composite floor slabs of one specification, cast-in-place concrete composite floor slabs of different specifications are usually needed on a construction site, and therefore cast-in-place concrete composite floor slab preparing and forming devices of different models are needed, the production cost is high, the occupied area of the devices is large, and the construction progress is affected; and in the traditional cast-in-place concrete composite floor slab preparing and forming process, due to the fact that in the concrete pouring process, contact between concrete and aggregate is possibly incomplete, the concrete is not in complete contact with the aggregate after standing and solidifying, and the cast-in-place concrete composite floor slab is prone to being broken.

Description

technical field [0001] The invention relates to the field of cast-in-place concrete laminated floors, in particular to a construction method for cast-in-situ concrete laminated floors. Background technique [0002] The cast-in-place concrete laminated floor slab is an assembled integral floor slab formed by laminating prefabricated aggregates and cast-in-place reinforced concrete. The cast-in-place concrete laminated floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the decorative layer. It is suitable for For high-rise buildings and large-bay buildings that require high overall rigidity, the cast-in-place concrete laminated floor slabs are usually fabricated on the construction site, which greatly reduces the cumbersomeness of the cast-in-place concrete laminated floor slabs from the preparation site to the construction site. [0003] At present, the following problems exist in the molding and prepara...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the molding and preparation process of cast-in-place concrete laminated slabs: a. During the preparation and molding process of traditional cast-in-place concrete laminated slabs, a preparation and molding device for cast-in-place concrete laminated slabs can only produce one specification The cast-in-place concrete laminated floor slab usually requires different specifications of cast-in-place concrete laminated floor slabs at the construction site, so different types of cast-in-place concrete laminated floor slabs are required to prepare molding devices, the production cost is high, and the device occupies a large area , affecting the construction progress, b During the preparation and molding process of traditional cast-in-place concrete laminated slabs, the contact between concrete and aggregate may not be complete during the pouring process, resulting in incomplete contact between concrete and aggregate after standing and solidifying. It is easy to cause the cast-in-place concrete laminated floor to break and affect the quality of the building
