Building floor slab and composite floor system

Abstract

The invention relates to the technical field of building floor slabs, in particular to a building floor slab and a composite floor system. A precast concrete slab is included, bottom steel bars are embedded in the bottom of the precast concrete slab, a plurality of edge reinforcement pieces are embedded on the precast concrete slab, the edge reinforcement pieces and the bottom steel bars are fixed, the edge reinforcement pieces are located at the edge portions of the precast concrete slab, and the boundary connection strength is better.

Description

technical field [0001] The invention relates to the technical field of building floors, in particular to a building floor and a combined floor. Background technique [0002] In the prefabricated building structure system, the floor system occupies an important position. It not only bears the vertical load, but also plays the role of transmitting the horizontal load. It plays a vital role in the integrity of the prefabricated building and the seismic capacity of the prefabricated building. important role. At present, prefabricated concrete floors are often used in prefabricated construction projects. Common forms include SP hollow slabs, double T slabs, truss reinforced concrete laminated slabs, etc. SP hollow slabs have a wide range of applications and can be used in schools, shopping malls, factories, warehouses and other buildings; Double T-slabs have a large span and are mostly used in large-space buildings such as industrial plants and shopping malls; truss reinforced c...

Problems solved by technology

Disadvantages of truss reinforced concrete laminated slabs: truss reinforcement is processed by professional equipment, and its web reinforcement only plays a mechanical role in the construction profession, resulting in waste of labor and materials; the unsupported span in the construction stage is small, it is difficult to implement unsupported construction, and a lot of waste The cost of temporary construction measures; all the gluten needs to be bound on site, and the composite layer concrete of the overall structure is poured on site. Now the construction workload is heavy, the construction progress is slow, and it is not conducive to the implementation of green construction

For example, the Chinese patent with the publication number 101173542A discloses a two-way steel-laminated slab concrete composite floor, which relates to a new type of large-span floor structure. Composed of post-cast concrete, the cross steel beams are I-shaped or box-section steel beams; The grid between the beams; the post-cast concrete is the concrete poured above the prefabricated slabs and steel beams, so there are problems of on-site pouring and a large amount of wet work. In addition, the integrity of the structure is not good enough, and the connection of the floor boundary ability is not good enough
