Bearing type base plate member

Abstract

A load-bearing base plate member, comprising a base plate (1), characterized in that it further comprises a truss (2) with at least one interchange, the truss (2) is arranged on the base plate (1), and the truss (2) is connected to the base plate (1) Connected to form a whole, the truss (2) is provided with an upper chord (3), a lower chord (4), and a web (5), and the web (5) is connected with the upper chord (3) and the lower chord (4). 2) at least one cavity member (6) is provided on at least one side, the cavity member (6) is an open cavity member, the open cavity member (6) is movably connected with the bottom plate (1), and the open cavity member ( 6) There is a connecting piece (7) for connecting the truss (2), and the connecting piece (7) connects the open cavity member (6) and the truss (2) into a whole. It is suitable for all kinds of cast-in-place reinforced concrete or prestressed reinforced concrete hollow slabs, floors, roofs, foundation floors, walls and bridges, especially for beamless floors.

Description

(1) Technical field [0001] The invention relates to a load-bearing floor member. (2) Background technology [0002] At present, the floors and roofs of multi-high-rise buildings are mainly cast-in-place concrete as a whole. The general construction method is to set up temporary scaffolding at the construction site, set up the bottom plate, and configure steel bars according to needs, and then perform concrete on site. pouring. The so-called prefabricated floor is manufactured in the factory in advance instead of the floor construction on site. Then this prefabricated floor is moved into the site and installed on the corresponding scaffolding for construction. Due to its advanced workability, the construction period can be shortened, so It has been widely used in recent years. Such prefabricated base plates include profiled steel plates, concrete base plates and prestressed concrete base plates, etc. However, there are also some problems in the construction and application ...

AI Technical Summary

Problems solved by technology

", in this utility model patent scheme, the floor slab is composed of multiple reinforced concrete prefabricated components, and the two-way structure is formed by forming a criss-cross layout with existing steel bars and reinforced concrete prefabricated components, without the need for on-site formwork. The existing steel bars and the original steel bars of reinforced concrete prefabricated components form a criss-cross layout, which can bear two-way loads. However, the shear capacity of the superimposed interface between the cast-in-place concrete and the bottom slab in this kind of floor is low, and the floor or roof The steel bars, concrete and other materials used in the construction of the cover are large in consumption, high in cost and poor in integrity
