Hollow slab form used for building and construction method

Abstract

The invention discloses a hollow slab form used for a building and a construction method. The hollow slab form comprises a side template (1) and a prefabricated soleplate (8), wherein the side template (1) is dislocated and lapped by a lower side template (2) and an upper side template (3), and a hole or a notch (4) is arranged at the bottom of the lower side template (2) and is located at the inner side of the upper side template (3). The construction method comprises the following steps: a bottom template (11) is supported, a rib beam reinforcing steel bar (10) is bound, and the spliced side template (1) is placed; the prefabricated soleplate (8) is placed on a support part (7), and a horizontal support is provided; the concrete is poured, after the concrete reaches a certain intensity, the lower side template (2) is dismounted, the prefabricated soleplate (8) is arranged on the support rib (7), and mortar is painted on the prefabricated soleplate to form the hollow slab. The hollow slab form has the advantages of less material consumption, easiness in splicing, recycling, simple construction, and capability of minimizing widths of seams between the prefabricated soleplate and cast-in-place dense ribs, and improving integrity of the hollow slab.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a hollow-core slab formwork for building and a construction method. Background technique: [0002] Reinforced concrete cast-in-situ hollow-core slabs have many advantages such as saving building materials, reducing the weight of the floor, good building energy-saving effect, convenient construction, convenient pipeline layout, good thermal insulation effect, and suitable for large-span and large-space buildings. [0003] There is a hollow-core slab formwork for construction (patent application number 201010558067.9), which is composed of modules, corner molds, bolts or bolts, prefabricated bottom plates, and assembled from multiple modules. The topmost module of the hollow-core slab formwork is a corner module, and the other modules are channel modules. Place the prefabricated bottom plate on the bottom plate of the corner module, and cover the gap between the end of the pre...

AI Technical Summary

Problems solved by technology

[0004] The building formwork can be assembled and disassembled flexibly, but there are relatively many assembly processes, the assembly and disassembly are relatively troublesome, and the cost of the formwork is relatively high; at the same time, after the prefabricated bottom plate is placed on the support ribs, there is a wide gap between the prefabricated bottom plate and the cast-in-place ribs. The gaps around the prefabricated floor make it difficult for the mortar to fill the gaps when the mortar is painted under the prefabricated floor. The wider gaps destroy the integrity of the hollow floor and reduce the rigidity and bearing capacity of the hollow floor.
