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 the reinforced concrete prefabricated components form a criss-cross layout, which can bear two-way loads. However, the longitudinal rib structure of this component causes a transverse partition, which is not convenient for pipeline penetration. The shear resistance of the joint interface is low, and the materials such as steel bars and concrete used in floor or roof construction consume a lot, the cost is high, and the integrity is poor

Abstract

The invention relates to a structural stressed superposed component used for a concrete floor system, the superposed component is composed of a soleplate (1) and is characterized in that the invention also is provided with a top boom (2) and a web member (3); wherein, the top boom (2) is connected with the template (1) into a whole through the web member (3) thereby forming a force-bearing component of a truss board (4); the soleplate (1) is internally provided with at least a reinforcing steel bar (5) parallel to the top boom (2); the top boom (2) is connected with the reinforcing steel bar (5) into a whole. The invention is applicable to cast-in-situ reinforced concrete or a hollow floor system, a roof system, walls and a foundation slab of the prestressed reinforced concrete as well as a vierendeel bridge girder, and is particularly suitable for a hollow flat slab.

Description

(1) Technical field [0001] The invention relates to a structural load-bearing composite component for a concrete floor. (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 proble...
