Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure connection node. Background Art

[0002] With the continuous development of modern construction technology, steel structures have been widely used in high-rise buildings, large-span buildings and other fields due to their advantages such as light weight, high strength and fast construction speed. However, the design and construction of steel structure connection nodes have always been a key problem in engineering practice. Traditional steel structure connection nodes often have problems such as complex construction and insufficient connection strength, which makes it difficult to meet the requirements of modern buildings for structural safety, construction efficiency and economy.

[0003] Existing steel structure connection nodes are insufficient in terms of adaptability. Due to the different sizes and shapes of different types of steel structures, traditional connection nodes are often difficult to adapt to the connection requirements of various types of steel structures, resulting in reduced construction efficiency and increased costs.

[0004] Therefore, based on the above search and in combination with the prior art, a steel structure connection node is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a steel structure connection node to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A steel structure connection node comprises a steel structure body, on the outer surface of which a first connection block, a second connection block, a third connection block and a fourth connection block are respectively arranged, and on the adjacent surfaces of the first connection block, the second connection block, the third connection block and the fourth connection block, a plurality of telescopic rods are fixedly installed; and an adjustment component is arranged on the steel structure body.

[0008] Furthermore, the adjustment component includes: two fixed blocks, the two fixed blocks are respectively arranged on the left side walls of the first connecting block and the third connecting block and the front side walls of the first connecting block and the second connecting block, the side walls of the two fixed blocks are each provided with a through groove, the interiors of the two through grooves are rotatably connected with threaded rods through bearings, adjacent ends of the two threaded rods pass through the side walls of the through grooves and extend to the outside of the fixed blocks, and the ends of the two threaded rods extending out of the fixed blocks are fixedly installed with bevel gears, and the two bevel gears are meshed with each other.

[0009] Furthermore, the adjustment component further includes: two sliders, the two sliders are respectively threadedly connected to the two threaded rods, the two sliders slide on the two through grooves respectively, and the adjustment component further includes a limiter.

[0010] Furthermore, the limiting member includes: a pin, which is arranged on a fixed block on the right side wall of the first connecting block and the third connecting block, a top surface of the fixed block on the right side wall of the first connecting block and the third connecting block and a bottom surface of the through groove are both provided with a plurality of circular holes, and a top surface of the sliding block on the right side wall of the first connecting block and the third connecting block is provided with a through hole.

[0011] Furthermore, the circular hole and the through hole are slidably connected with a same latch, and a pull ring is fixedly mounted on the top surface of the latch.

[0012] Furthermore, a rotating handle is rotatably connected to the side wall of one of the fixed blocks, and the rotating handle is connected to the side wall of one of the threaded rods.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up an adjustment component, the adaptability of the steel structure connection node to different types of steel structures is realized. The adjustment component uses two mutually meshing bevel gears. By rotating one of the threaded rods, the two threaded rods can be rotated synchronously, thereby driving the slider to move, thereby changing the structural form of the connection node. This design is not only easy to operate, but also can flexibly cope with different types of steel structures, improving the applicability and practicality of the equipment;

[0015] 2. By setting the limiter, the stability and safety of the connection node during the adjustment process are effectively guaranteed. The limiter adopts a pin structure. The position of the slider and the connection block is restricted by the sliding of the pin in the round hole and the through hole, thereby avoiding looseness or dislocation that may occur during the adjustment process. This design not only enhances the structural stability of the connection node, but also ensures that the connection node has good bearing capacity and safety performance when subjected to external forces.

The ends of the two threaded rods 9 extending out of the fixed blocks 7 are fixedly installed with bevel gears 12. The two bevel gears 12 are meshed with each other.

[0026] Working principle:

[0027] When in use, the steel structure connection node is mainly composed of a steel structure body 1 and a first connection block 2, a second connection block 3, a third connection block 4 and a fourth connection block 5 arranged on its outer surface. A plurality of telescopic rods 6 are installed on the adjacent surfaces of the four connection blocks. These telescopic rods 6 provide basic structural support and connection functions for the connection node. When it is necessary to adjust the structure of the connection node to adapt to different types of steel structures, one of the threaded rods 9 can be rotated. The rotation of this threaded rod 9 will drive the bevel gear 12 on it to rotate. Since the two bevel gears 12 are meshed with each other, the rotation of one bevel gear 12 will drive the other bevel gear 12 and the corresponding threaded rod 9 to rotate. The rotation of the threaded rod 9 will produce relative movement of the slider 10 threadedly connected thereto. The slider 10 is fixedly connected to the right side wall of the fourth connection block 5 and the front side wall of the second connection block 3. Therefore, the movement of the slider 10 will drive the third connection block 4 and the second connection block 3 to move to the rear and left sides respectively. This movement makes the connection The structure of the connection node changes, thereby achieving adaptive connection for different types of steel structures. For the convenience of adjustment, after the adjustment is completed, it is fixed again by multiple high-strength bolts to avoid the displacement of the steel structure body 1. A rotating handle 11 is also rotatably connected to the side wall of one of the fixed blocks 7. The rotating handle 11 is connected to the side wall of one of the threaded rods 9, so that the user can easily rotate the threaded rod 9 by rotating the handle 11. In order to ensure the stability and safety of the connection node, a limiter is also provided. The limiter includes a latch 13, which is provided on the fixed block 7 on the right side wall of the first connection block 2 and the third connection block 4. The top surface of the fixed block 7 and the bottom surface of the through groove 8 are both provided with multiple circular holes 14, and the top surface of the slider 10 is provided with a through hole 15. The latch 13 can slide in the circular hole 14 and the through hole 15, thereby limiting the position of the slider 10 and the connection block, ensuring the stability and safety of the connection node during the adjustment process, and a pull ring 16 is also fixed on the top surface of the latch 13 for user convenience.
