Description

Technical Field

[0001] This utility model belongs to the field of steel structure building technology, and in particular relates to the rapid splicing node structure of prefabricated steel structure buildings. Background Technology

[0002] Prefabricated steel structure buildings are constructed by transporting prefabricated steel structure components from the factory to the site for assembly. They have advantages such as fast construction speed, high degree of industrialization, energy saving and environmental protection, which are in line with the concept of green building development. In this type of building, the splicing node structure is extremely critical, as it relates to the overall stability and load-bearing capacity of the steel structure. Traditional splicing nodes have defects such as weak load-bearing capacity, many bolts, and inconvenience in disassembly and assembly, which make it difficult to meet the current building requirements. Therefore, it is imperative to develop splicing node structures with better performance.

[0003] However, the existing prefabricated steel structure splicing node structure is relatively complex and cumbersome to install during use, which greatly increases the time and labor costs of on-site construction. When faced with a large amount of construction work, it will prolong the overall construction time and delay the construction progress. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-assembly node structure for prefabricated steel structure buildings. By setting up a connecting part, it solves the problem that the existing splicing node structures for prefabricated steel structure buildings are complicated and cumbersome to install, which greatly increases the time and labor costs of on-site construction. When faced with a large amount of construction work, it will prolong the overall construction time and delay the construction progress.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a rapid assembly node structure for prefabricated steel structure buildings, including a steel structure one and a steel structure two set at the bottom of the steel structure one, and also includes: a connecting part, the connecting part being set at the bottom of the steel structure one; and an anti-detachment part, the anti-detachment part being set at the top of the steel structure two; wherein, the top of the anti-detachment part extends into the steel structure one, and the steel structure one is a rod with a connecting block at the bottom.

[0007] Furthermore, the connecting part includes an upper shell assembly disposed at the bottom of a steel structure; and two buckle assemblies, both of which are located at the bottom of the steel structure; wherein the two buckle assemblies are mirror images of each other, and the tops of both buckle assemblies extend into the upper shell assembly.

[0008] Furthermore, the anti-detachment part includes a limiting component disposed at the top of a steel structure; and a limiting component installed at the bottom of a steel structure; wherein the bottom of the limiting component extends into the limiting component.

[0009] Furthermore, the upper shell assembly includes an outer shell one fixedly connected to the bottom of the steel structure one. A top plate is slidably connected to the inner wall of the outer shell one. Several spring telescopic rods are fixedly connected to the top of the top plate. A snap-fit ​​component is provided at the bottom of the outer shell one. Among them, there are four spring telescopic rods, and the tops of the four spring telescopic rods are fixedly connected to the outer shell one. The snap-fit ​​component includes a slider slidably connected to the inner wall of the outer shell two. The bottom of the slider is fixedly connected to a limiting block three, and the top of the slider is fixedly connected to a limiting block one. Among them, the limiting block one is a block that is wider at the top and narrower at the bottom. The top plate is buffered by the spring telescopic rods, and the snap-fit ​​component cooperates with other components to achieve connection.

[0010] Furthermore, the buckle assembly includes a clamping block slidably connected to the inner wall of the outer shell. Two springs are fixedly connected to the side of the clamping block away from the limiting block. Two limiting members are provided on the clamping block. The sides of the two springs away from the clamping block are fixedly connected to the outer shell. The two limiting members are mirror images of each other. The limiting member includes a limiting block two fixedly connected to the top plate near the clamping block. A limiting groove is formed on the clamping block. The limiting groove passes through the clamping block, and the shape of the limiting groove is adapted to the limiting block two. The clamping block achieves clamping and limiting with the upper shell assembly through the springs and the limiting members.

[0011] Furthermore, the limiting component includes a second outer shell fixedly connected to the top of the second steel structure. A third limiting block is slidably connected to the inner wall of the second outer shell. Two fasteners are provided inside the second outer shell. The third limiting block is a block with several grooves, and the two fasteners are mirror images of each other, located on opposite sides of the third limiting block. Each fastener includes a fourth limiting block slidably connected to the inner wall of the second outer shell. A limiting rod is located on the side of the fourth limiting block away from the third limiting block. A second spring is sleeved on the outer wall of the limiting rod. A portion of the limiting rod extends beyond the fourth limiting block to the outside of the second outer shell. The outer wall of the limiting rod is slidably connected to the second outer shell, while the fourth limiting block is adapted to the third limiting block. The side of the second spring closest to the second outer shell is fixedly connected to the second outer shell, and the side of the second spring furthest from the second outer shell is fixedly connected to the limiting rod. The third limiting block cooperates with the fasteners to restrict and fix the position of the second steel structure.

[0012] Furthermore, the limiting component includes an anti-detachment sleeve slidably connected to the outer wall of the steel structure, and two springs are provided inside the anti-detachment sleeve; wherein, the top of the two springs is fixedly connected to the steel structure, and the bottom of the two springs is fixedly connected to the anti-detachment sleeve, and the anti-detachment sleeve achieves sliding limitation on the steel structure through the springs to prevent it from falling off.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting the connecting part, when installation is required, steel structure one can be held by hand and inserted into steel structure two. At this time, the anti-detachment sleeve will first be put on the outer shell two and restrict the two limiting rods. The limiting block one is inserted between the two clamping blocks, and then steel structure one is pressed down. Under the action of the two limiting rods, the slider will drive the limiting block one to push the top plate out between the two clamping blocks. At this time, several spring telescopic rods will be compressed and generate elastic force. When the top plate is pushed out between the two clamping blocks, the two clamping blocks will approach each other under the action of several springs one and clamp the limiting block one. At this time, the two limiting blocks two will slide into the limiting groove respectively. Under the action of the elastic force of several spring telescopic rods and the elastic force of several springs one, the two clamping blocks will fix the limiting block one. Steel structure one and steel structure two can be fixed together by simple pressing. The operation is simple and convenient, which greatly reduces the time and labor costs of on-site construction. When facing a large amount of construction, the steel structure support can be installed quickly, thus ensuring the smooth progress of construction.

[0015] 2. By setting up an anti-detachment part, after the connecting part is inserted, the anti-detachment sleeve can be pushed upward, thereby compressing the two springs and generating elastic force. When the anti-detachment sleeve slides upward, it will move away from the two limiting rods, thereby releasing the restriction on the two limiting rods. Then, continue to press the steel structure one, so that it drives the limiting block three to slide inside the outer shell two through the connecting part. At this time, it will squeeze the two limiting blocks four, thereby stretching the two springs two under the action of the two limiting rods and generating elastic force. When the limiting block three slides completely into the outer shell two, under the action of the elastic force of the two springs two, it will drive the two limiting blocks four to lock on the limiting block three through the two limiting rods. Then the anti-detachment sleeve can be released. At this time, under the action of the elastic force of the two springs three, it will cover the outer shell two and restrict the two limiting rods again, which can further connect the steel structure one and the steel structure two together, lock them firmly, and prevent the structure from loosening due to vibration and falling off, thereby ensuring the stability of the building structure connection.

[0030] A specific application of this embodiment is as follows: During use, when installation is required, steel structure 101 can be held by hand and inserted into steel structure 202. At this time, the anti-detachment sleeve 321 will first be placed on the outer shell 211 and restrict the two limiting rods 314.

Between blocks 221, several spring telescopic rods 213 will compress and generate elastic force.

Secure the limiting block 215. After inserting the connecting part 2, push the anti-disengagement sleeve 321 upwards, thereby compressing the two springs 322 and generating elastic force. When the anti-disengagement sleeve 321 slides upwards, it will move away from the two limiting rods 314, thereby releasing the restriction on the two limiting rods 314. Then continue to press the steel structure 101, so that it drives the limiting block 312 to slide inside the outer shell 2 311 through the connecting part 2. At this time, it will squeeze the two limiting blocks 313. Thus, under the action of the two limiting rods 314, the two springs 315 are stretched and generate elastic force. When the limiting block 312 slides completely into the outer shell 311, under the action of the elastic force of the two springs 315, the two limiting blocks 313 will be driven by the two limiting rods 314 to lock onto the limiting block 312. Then the anti-detachment sleeve 321 can be released.
