Additional rigidity piece composite floor slab

Abstract

The invention discloses an additional rigidity piece composite floor slab. The composite floor slab comprises a composite floor slab body and a plurality of additional rigidity pieces, wherein the composite floor slab body comprises a prefabricated floor slab and a plurality of concrete protruding blocks arranged on the prefabricated floor slab body, the additional rigidity pieces are channel steel or C-shaped steel, openings of the additional rigidity pieces are arranged downwards, the additional rigidity pieces cover the multiple concrete protruding blocks, the end faces of the two side walls of the additional rigidity pieces are attached to the prefabricated floor slab body, and the additional rigidity pieces are detachably and fixedly connected with the concrete protruding blocks. According to the scheme, the composite floor slab with the additional rigidity pieces is good in rigidity, the efficiency is greatly improved in the aspects of the structure, the manufacturing and the production process, resources and materials are saved, and the cost is comprehensively reduced.

Description

technical field [0001] The invention relates to a laminated floor, in particular to a laminated floor with additional rigidity parts. Background technique [0002] At present, the mainstream of prefabricated prefabricated laminated slabs in China is truss reinforced laminated slabs. At present, the mainstream laminated slabs in China have the following disadvantages: (1) There are truss reinforcements. 50%-60% higher); (2) The thickness of the base plate of the laminated slab is large (usually 60mm thick), resulting in a large overall thickness of the floor slab (60mm of the base plate + 80mm of the laminated layer, the total thickness reaches 140mm, which is thicker than the traditional cast-in-place 100mm 40%), the cost is high, and the weight of the structure is heavy, which further leads to the weight of the whole house and the steel bar content; (3) The ribs at the end of the floor and the side of the slab lead to complex production molds in the factory, and the complex...

[0002] At present, the mainstream of prefabricated prefabricated laminated slabs in China is truss reinforced laminated slabs. At present, the mainstream laminated slabs in China have the following disadvantages: (1) There are truss reinforcements. 50%-60% higher); (2) The thickness of the base plate of the laminated slab is large (usually 60mm thick), resulting in a large overall thickness of the floor slab (60mm of the base plate + 80mm of the laminated layer, the total thickness reaches 140mm, which is thicker than the traditional cast-in-place 100mm 40%), the cost is high, and the weight of the structure is heavy, which further leads to the weight of the whole house and the steel bar content; (3) The ribs at the end of the floor and the side of the slab lead to complex production molds in the factory, and the complexity of the bottom mold on the slab side of the two-way slab, resulting in manufacturing and The construction process is complicated; (4) Due to the height limit of the truss, it is difficult to thread the pipeline on site, making the site construction complicated, the plate thickness is generally super thick, and the cost is increased; (5) The site formwork and support density at the bottom of the plate is high, resulting in construction Difficult, did not take advantage of assembly

[0006] Its disadvantage is that the metal pipe grouted inside replaces the top reinforcement of the truss steel bar. The steel pipe truss part will further increase the cost of the ordinary truss steel bar, resulting in too high steel content of the prefabricated panel itself, and due to the larger diameter of the truss tube, it will be more expensive. It is not conducive to the passage and laying of on-site pipelines, and the thickness of the laminated layer will be larger than that of ordinary truss laminated plates
