Problems solved by technology

In order to achieve this goal, the current prefabricated buildings mostly use cast-in-situ concrete floors, concrete laminated floors, and profiled steel plate concrete composite floors. The biggest advantage of these methods is good integrity, but there are a lot of wet work and the construction period is long. Has become the fetters of prefabricated structures
[0005] In addition, the earthquake damage shows that the slab joint connection method of the existing prefabricated floor slabs is not reliable, and it is difficult to effectively pull the prefabricated slabs together. Under the action of the earthquake, the phenomenon of wall collapse and house collapse will seriously endanger human life and property safety

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Please refer to figure 1 , figure 2 , figure 1 Schematic diagram of the structure of the prefabricated floor slab provided by the present invention; figure 2 for figure 1 Schematic diagram of splicing of prefabricated slabs shown.

[0032] As shown in the figure, in a specific embodiment, the geometric dimensions of the prefabricated floor 1 provided by the present invention are divided into two types: slab width 900 mm and 1200 mm, slab length between 2400 mm and 3600 mm, with 300 mm as the unit, and slab thickness It is divided into two types: 80mm and 100mm, which can be determined according to the slab length and load design. The length of the prefabricated floor slab shown in the figure is 3000mm and the width is 1...

Abstract

The invention discloses a prefabricated floor slab. Split shear key grooves (1-1) which are perpendicular to the length direction of the prefabricated floor slab (1) are formed in one side or two sides of the long edge of the prefabricated floor slab (1), split connecting key grooves (1-2) which are parallel to the length direction of the prefabricated floor slab are formed in one side or two sides of the short edge of the prefabricated floor slab, and the split shear key grooves (1-1) and the split connecting key grooves (1-2) are through holes or sunken grooves which are through up and down. According to the prefabricated floor slab, a plurality of prefabricated floor slabs can be combined to form a whole floor slab by shear keys and continuous keys, so that an overall pouring effect is achieved, the integrity and the continuity of the floor slab are guaranteed, and the assumption that the rigidity of the prefabricated slab is infinite in a plane is realized.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to prefabricated floor slabs of buildings. The invention also relates to a prefabricated floor structural member formed by combining multiple prefabricated floor slabs. Background technique [0002] Reinforced concrete floor slabs are made of concrete and steel bars. This kind of floor slab is strong, durable, high in rigidity, high in strength, and good in fire resistance, and is currently widely used. According to the construction method, it can be divided into two categories: cast-in-place reinforced concrete floor slab and fabricated reinforced concrete floor slab. [0003] Prefabricated reinforced concrete floor slab refers to the reinforced concrete floor slab prefabricated outside the component prefabrication processing factory or the construction site, and then transported to the construction site for installation. The length of the prefabricated slab is genera...
