Description

A multi-layer precast beam component Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a multi-layer precast beam component. Background Technology

[0002] In the field of modern building construction, the application of precast components is becoming increasingly widespread. Among them, precast beams, as key structural components, directly affect the overall safety and construction efficiency of building projects. Traditional precast beams suffer from problems such as large self-weight, insufficient seismic performance, and inadequate protection against steel corrosion. This utility model aims to provide an innovative precast beam component to overcome the shortcomings of existing technologies and meet the demands of modern buildings for high-performance precast components.

[0003] Traditional precast beam components are mostly single-layer structures, and are often cast with ordinary concrete, resulting in insufficient strength and limited load-bearing capacity. Furthermore, with long-term use, corrosion will occur on the surface of the precast beam components, affecting the internal structure, accelerating the fracture of the precast beam components, reducing their service life, and creating significant safety hazards. In addition, the bolts at the connection between the cross plate and the load-bearing bar are prone to loosening, leading to insufficient stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer precast beam component, which has advantages such as multi-layer structure and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned multi-layer structure objective, this utility model provides the following technical solution: a multi-layer precast beam component, comprising two load-bearing rods, four connecting strips and a cross plate, wherein multiple connecting rods are provided between the two load-bearing rods, and multiple steel reinforcement frames are provided on both sides of the load-bearing rods;

[0006] The load-bearing rod has a steel reinforcement layer inside, a steel plate layer outside the steel reinforcement layer, a concrete layer outside the steel plate layer, and a protective layer outside the concrete layer.

[0007] As a further improvement of this utility model, the steel reinforcement layer is formed by twisting together multiple steel bars, which improves the firmness between the steel bars and thus increases the strength.

[0008] As a further improvement of this utility model, the protective layer is made of FRP fiber cloth and coated with resin. The protective layer can improve the corrosion resistance of the load-bearing rod surface and increase its service life.

[0009] As a further improvement of this utility model: four mounting posts are provided on both sides of the horizontal plate, and four connecting holes are provided on the upper part of both sides of the load-bearing rod. The mounting posts are inserted into the connecting holes, and nuts are screwed into the mounting posts to tighten and fix them.

[0010] As a further improvement of this utility model, two fixing bolts are installed on the surface of each connecting strip. Tightening the fixing bolts fixes the connecting strip, preventing loosening and improving its firmness.

[0011] As a further improvement of this utility model: each of the load-bearing rods is equipped with a base at its lower end, and each of the four corners of the upper end of the base is provided with a locking bolt. Tightening the locking bolts fixes the two bases and improves stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the protective layer can improve the corrosion resistance of the surface of the load-bearing rod and increase its service life. The load-bearing rod adopts a multi-layer structure. The steel bar layer and steel plate layer can improve the strength of the load-bearing rod, improve its compressive strength, avoid affecting the interior, avoid breakage, increase its service life, and prevent safety hazards.

[0014] 2. In this utility model, the mounting column is tightened and fixed by screwing nuts into it, and then the connecting strip is installed on the outer end of the mounting column. The fixing bolts are then tightened to fix the connecting strip, which prevents loosening and improves the firmness. Attached Figure Description
