Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel structure building technology, and in particular to a floor connection component. Background Technology

[0002] Most components of prefabricated steel structure buildings are prefabricated in factories, requiring only assembly and connection on-site, significantly shortening the construction cycle and reducing on-site wet work and labor requirements. Columns, as the main load-bearing components, bear the heavy responsibility of transferring the building load to the foundation. Beams connect to the columns to form a stable frame structure, supporting the floor slabs and resisting horizontal and vertical loads. Floor connection components are key parts used to reliably connect the columns and beams of upper and lower floors. They not only ensure the integrity and continuity of the structure but also guarantee the accuracy and connection strength of the prefabricated components during installation. It can be said that it is through these connectors that the dispersed columns and beams are efficiently and firmly combined, forming a safe and stable prefabricated steel structure building system. However, existing floor connection components have high requirements for installation alignment accuracy and poor error tolerance. Dimensional deviations in steel structure components or hoisting errors can easily lead to misalignment of bolt holes, requiring on-site hole enlargement or adjustment, affecting progress. Some floor connection components lack sufficient rigidity, easily causing deformation or stress concentration, affecting the overall structural performance.

[0003] Therefore, there is an urgent need for a floor connection component with strong fault tolerance and structural stability. Utility Model Content

The side of the second connection unit 2 is provided with symmetrical circular holes 21.

[0021] The first connecting unit 1 can be sleeved or fixed to the column, and is bolted to the column through the first strip holes 11 on both the front and rear sides. One side of the second connecting unit 2 can be fixed to the first connecting unit 1 by welding, and the round hole 21 is used for high-strength bolt connection to the end of the crossbeam. The setting of the first strip hole 11 provides vertical adjustment margin, allowing for fine adjustment of the position of the first connecting unit 1 relative to the column during installation, effectively compensating for manufacturing and installation errors and improving assembly fault tolerance. The first connecting unit 1 of the square tube structure has good compressive, bending and torsional resistance. As the main load-bearing component, it can effectively transmit the axial force and bending moment of the column. The second connecting unit 2 of the U-shaped structure provides stable lateral support for the crossbeam, enhances the constraint on the end of the crossbeam, and the setting of the round hole 21 ensures uniform stress on the connection with the crossbeam, thereby improving the overall rigidity of the floor connection assembly. This solves the problems of high installation alignment accuracy requirements, poor fault tolerance, insufficient stiffness of connection nodes, and impact on the overall structural performance of existing floor connection assemblies.

By setting the second strip hole 12, the adjustment freedom of the column is increased, better adapting to possible deviations on the construction site and improving installation efficiency.

[0026] Two first strip holes 11 symmetrically arranged on the front and rear sides of the first connecting unit 1 form a group; the first strip holes 11 provide vertical adjustment margin for the column. The setting of the third strip hole 13 increases the adjustment freedom of the column, better adapts to possible deviations on the construction site, and improves installation efficiency. The second connecting unit 2 is located in the middle of the first connecting unit 1, so that the top and bottom of the first connecting unit 1 can participate in load-bearing, improving the bending and shear stiffness of the overall structure.

The first strip holes 11 are symmetrical to each other and are arranged along the length direction of the first connection unit 1. The second connection unit 2 is a U-shaped structure, and the U-shaped opening 22 on one side of the second connection unit 2 is fixedly connected to the first connection unit 1. The side of the second connection unit 2 is provided with symmetrical circular holes 21.

[0028] The second connecting unit 2 is located in the middle of the first connecting unit 1. The first strip hole 11 is provided in at least two sets and is located at the top and bottom of the first connecting unit 1 respectively. The left and right sides of the top and the left and right sides of the bottom of the first connecting unit 1 are provided with third strip holes 13. The third strip holes 13 are symmetrical to each other and are arranged along the length direction of the first connecting unit 1.

[0029] The difference between this embodiment and embodiment two is that: the second connecting unit 2 has 4 units, which are respectively connected to the four side walls of the middle part of the first connecting unit 1.

On the other hand, it enables the floor connectors to adapt to beams or components in different directions, improving the versatility of the components and making them suitable for complex spatial layouts.

[0031] Example 4 Reference Figure 4 A floor connection component includes a first connection unit 1 and a second connection unit 2. The first connection unit 1 is a square tube structure, and first strip holes 11 are provided on both the front and rear sides of the first connection unit 1.

Both the upper sliding plate 31 and the lower sliding plate 32 are U-shaped structures. The openings of the upper sliding plate 31 and the lower sliding plate 32 are arranged opposite to each other. The outer sides of the upper sliding plate 31 and the lower sliding plate 32 are provided with sliders 34. The inner side of the first connecting unit 1 is provided with a sliding groove 14, and the sliders 34 and the sliding groove 14 are slidably connected.

[0040] The difference between this embodiment and embodiment four is that the first connecting unit 1 is provided with an elastic damping layer 35, which is located inside the U-shaped opening 22.

[0041] The elastic damping layer 35 is specifically a rubber layer or a viscoelastic material.
