A connection structure for dislocation lap joint of assembled high and low laminated plates

Abstract

The present invention relates to a connection structure for dislocation lap joint of assembled high and low laminated panels, comprising prefabricated panels, built-in longitudinal steel parts, built-in transverse steel parts, truss steel parts, reinforced steel parts, built-in steel plates and a connecting mechanism, the prefabricated boards The interior is horizontally equipped with built-in horizontal steel parts, the interior of the prefabricated slab is vertically provided with built-in longitudinal steel parts, the top of the prefabricated slab is equipped with truss steel parts at equal intervals, the top of the truss steel parts is welded with reinforced steel parts, the two sides of the prefabricated board, etc. Built-in steel plates are embedded in the interval, and the built-in steel plates are located between two adjacent built-in horizontal steel parts. One end of the built-in steel plate is equipped with a connecting mechanism, and the steel fixing block is fixed on one end of the built-in steel plate by bolts. One end of the steel fixing block The connecting blocks are arranged at equal intervals, and the top of each connecting block is provided with a connecting jack. In the present invention, the installation gap of the laminated board can be adjusted according to the actual installation requirements, and the connection strength of the joint of the laminated board is greater after misplaced installation. , with higher security.

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
