Problems solved by technology

[0004] The purpose of the present invention is to provide an assembled tooth-shaped laminated floor slab. The present invention uses tooth-shaped occlusal, latch restraint, steel bar fixing and other means to limit the relative degrees of freedom of the two slabs, thereby reducing the deformation difference between the laminated slabs , to solve problems such as wrong platform and cracks in the construction

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the embodiments shown in the accompanying drawings.

[0026] The present invention has two forms, one is a rectangular tooth superimposed floor slab with a latch, and the other is a trapezoidal tooth superimposed floor without a latch. It is mainly composed of the following parts: bottom plate 1, segmented rib 2, latch groove 3, latch 4, lower longitudinal reinforcement 5, lower horizontal reinforcement 6, rectangular teeth 7, rectangular slots 8, trapezoidal teeth 9, trapezoidal slots 10.

[0027] The bottom plate 1 is wrapped with the lower longitudinal steel bar 5, on which there are two segmented ribs 2, and the longitudinal edge of the plate is set in a tooth shape. Latch groove 3 is set at the bottom plate, segmented rib 2, latch groove 3, bottom longitudinal steel bar 5, rectangular teeth 7, trapezoidal teeth 9, rectangular tooth grooves 8, trapezoidal tooth grooves 10 and other ...

Abstract

The invention relates to a building floor slab, in particular to an assembled-type tooth-shaped superposed floor slab. Lower-layer longitudinal rebars (5) are wrapped in a baseplate (1), two sectional-type rib strips (2) are arranged on the baseplate (1), and a longitudinal edge of a plate is arranged to be tooth-shaped. A rectangular-tooth superposed floor slab with latches is characterized in that latch grooves (3) are arranged at positions where rectangular teeth (7) are spliced with rectangular tooth grooves (8), the baseplate (1), the sectional-type rib strips (2), the latch grooves (3), bottom-layer longitudinal rebars (5), the rectangular teeth (7), trapezoidal teeth (9), the rectangular tooth grooves (8) and trapezoidal tooth grooves (10) are formed integrally by formwork-erecting pouring, two sectional-type rib strips (2) in staggered arrangement are arranged on each plate, and length of each rib strip is half of that of the corresponding plate. Relative degree of freedom of two plates is limited by means of tooth-shaped meshing, latch restraining, rebar fixing and the like, so that deformation difference among prefabricated slabs is reduced, and the problems of slab staggering, cracking and the like are solved.

Description

technical field [0001] The invention relates to a building floor, in particular to an assembled tooth-shaped laminated floor. Background technique [0002] The composite floor is a structural form that combines prefabricated slabs with cast-in-place technology. That is, after the prefabricated slab is produced on a large scale in the factory, the floor slab formed by transporting it to the construction site for re-casting has good integrity, sufficient rigidity and excellent crack resistance of the cast-in-place floor slab, and also has the no need for formwork of the prefabricated floor slab. Save consumables, shorten the construction period and other advantages. Therefore, it is widely used in the upper parts of multi-storey buildings and high-rise buildings. However, there are also some shortcomings of its own. For example, due to the excessive shear force at the superimposed surface, it is easy to cause the separation of the cast-in-place part and the prefabricated sla...
