Connecting structure for staggered overlapping of assembly type high and low laminated slabs

Abstract

The invention relates to a connecting structure for staggered overlapping of assembly type high and low laminated slabs. The connecting structure comprises a prefabricated slab, built-in longitudinalsteel bars, built-in transverse steel bars, truss steel bars, reinforcing steel bars, built-in steel plates and connecting mechanisms, wherein the built-in transverse steel bars are transversely arranged in the prefabricated slab, the built-in longitudinal steel bars are longitudinally arranged in the prefabricated slab, the truss steel bars are arranged on the top of the prefabricated plate at equal intervals, the reinforcing steel bars are welded to the tops of the truss steel bars, the built-in steel plates are embedded into both sides of the prefabricated plate at equal intervals and are located between every two adjacent built-in transverse steel bars, the connecting mechanisms are installed on one end of the built-in steel plates, steel fixed blocks are fixed to one end of the built-in steel plates through bolts, connecting blocks are arranged on one end of the steel fixed blocks at equal intervals, and connecting insertion holes are respectively formed in the tops of the connecting blocks. According to the connecting structure, the mounting gap of the laminated slabs can be adjusted according to the actual mounting requirement, after staggered installation is performed, theconnecting strength of the connecting position of the laminated slabs is high, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of building construction materials, in particular to a connection structure for dislocation and overlapping of assembled high and low laminated plates. Background technique [0002] Composite slab is a better structural form combining prefabricated slab and cast-in-place concrete. The prefabricated prestressed slabs are combined with the upper cast-in-place concrete layer as a whole and work together. The prestressed main reinforcement of the prefabricated thin slab is the main reinforcement of the laminated slab, and the upper concrete cast-in-place layer is only equipped with negative moment reinforcement and structural reinforcement. The prestressed slab is used as the bottom form for the cast-in-place concrete course, and it is not necessary to support the formwork for the cast-in-place course. The bottom surface of the thin board is smooth and flat, and the ceiling can no longer be plastered after the...

Problems solved by technology

[0003] However, there are the following problems in the use of a prefabricated high-low laminated plate dislocation lap connection structure in the current market. Since the length of the steel parts is unique, when the installation gap between the laminated plates is smaller than the actual length of the connected steel parts, the steel parts need to be cut manually, resulting in poor practicability and cannot be applied to the laminated plates with different gaps. b. The traditional assembly-type high-low laminated plate misalignment lap connection structure is used to fix the connecting steel parts by lap joints. This method uses thin steel wires to wrap around and lock the connection points , this overlapping process needs to be manually operated one by one, resulting in a long actual construction period of the laminated slab and low installation efficiency. At the same time, the connection strength of the fine steel joint is low, and the safety between the prefabricated slabs is poor
