Bottom template for building floorslab and construction method thereof

Abstract

The invention discloses a bottom template for a building floorslab and a construction method thereof. The bottom template for the building floorslab comprises supporting ends (1), connecting plates (2), connecting cover plate (3), angular placing parts (8) and a cover plate (9). The plurality of supporting ends (1) or / and the connecting plates (2) or / and the connecting cover plates (3) are spliced in sequence to form a #-shaped template; the angular placing parts (8) are fixed on the #-shaped template and the cover plate (9) is placed on the angular placing parts (8) to form the bottom template for the building floorslab. When the bottom template is detached, floorslab concrete is poured on the top of the bottom template before the angular placing parts (8) are detached, then the cover plate (9) is detached, and the supporting ends (1), the connecting plates (2) and the connecting cover plates (3) are detached after the floorslab concrete reaches the strength. The bottom template is suitable for the construction of a reinforced concrete hollow rib floorslab and the construction of the solid floorslab. During the construction of the hollow rib floorslab, the bottom template can be used so that the side template of the hollow rib floorslab can be detached conveniently and the standardized construction of the hollow rib floorslab can be realized.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a building floor formwork and a construction method thereof. Background technique: [0002] An existing reinforced concrete hollow floor slab (patent application number 200420035588.6) adopts the technology that reinforced concrete hollow prefabricated components are arranged vertically and horizontally on the bottom reinforced concrete, and the gaps between the vertically and horizontally arranged hollow prefabricated components are filled with reinforced concrete to form a dense structure. Ribs, forming hollow-core slabs. The patent with the publication number CN 1900449A is to place a plurality of hollow prefabricated component frames on the formwork, and the prefabricated component covers are covered on the hollow component frames, and the gaps between the vertically and horizontally arranged prefabricated components are filled with reinforced concrete to form dense ribs...

AI Technical Summary

Problems solved by technology

These two kinds of hollow floor slabs have the following disadvantages: a, steel bars and concrete consume a lot of materials, and the weight increases the cost of the floor slab; b, the integrity and impermeability of the floor slab are not good

[0004] Patent application No. 201010558067.9 proposes a formwork suitable for this kind of hollow floor slab. The formwork includes modules, corner forms, bolts or pins, and a prefabricated floor. The side formwork of the integral hollow slab is formed by connecting the angle formwork. The side formwork of the hollow slab is assembled from many modules. The formwork assembly is flexible, and the modules can be recycled after dismantling. However, the bottom formwork used in the construction of the ribbed hollow slab is as follows: Strip formwork and full formwork, when performing construction steps such as binding rib beam reinforcement and placing hollow floor side formwork on the strip formwork, construction safety cannot be guaranteed, causing construction and inconvenience, and full formwork is used for the application number 201010558067.9 During the construction of the densely ribbed hollow slab proposed by the patent, the side formwork of the hollow slab can only be removed after the full formwork is removed. Therefore, the full formwork and the side formwork of the hollow slab can only be removed after the densely ribbed concrete reaches the strength requirements. In this way, it will take a long time in the construction, and the construction period is very long, which is uneconomical and unreasonable.
