Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to a connection structure for irregularly shaped steel structure columns. Background Technology

[0002] In modern construction and heavy machinery manufacturing, steel structures are widely used due to their high strength and light weight. In these applications, it is often necessary to precisely and securely connect various standard or non-standard irregular steel structural components.

[0003] Currently, common connection methods mainly rely on high-strength bolts or on-site welding. During installation, hoisting equipment is needed to transport heavy, irregularly shaped steel plates to the designated location, followed by manual alignment and tightening. Due to the heavy weight and irregular shape of the components, precise alignment is extremely difficult. During final placement, hard collisions often occur between the components and the supporting foundation. This impact not only damages the anti-corrosion coating on the surface of the components but can also cause deformation or damage to the components themselves or the connecting foundation in severe cases. Furthermore, once the connection is completed, the entire node is a rigid connection. In the service environment, if the structural column is subjected to an accidental lateral impact from forklifts, transport vehicles, or other moving equipment, the enormous impact force will directly act on the connection node, causing the fastening bolts to loosen and the components to misalign, thereby affecting the safety and stability of the entire structure.

[0004] Therefore, this utility model proposes a non-standard steel structure column connection structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of irregular steel column connection structure, such as easy damage to components due to hard impact caused by gravity during installation, lack of lateral anti-collision protection and low reliability after connection, this utility model aims to provide an irregularly shaped adaptable steel column connection structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a non-standard steel structure column connection structure, including: connecting columns, non-standard steel plates disposed between the connecting columns; and buffer components, bolts, connecting plates and buffer pads.

[0007] The buffer assembly is disposed between the connecting columns and is used to elastically support the irregular steel plate during installation. It has a buffer structure including a support plate that can move up and down and a spring for elastically pushing the support plate.

[0008] Furthermore, the bolt, the connecting plate, and the buffer pad are combined in the following manner: the bolt passes through the connecting column and the irregular steel plate, the connecting plate is sleeved on the bolt and located outside the connecting column, and the buffer pad is sandwiched between the connecting plate and the irregular steel plate to achieve a fast connection and anti-collision protection.

[0009] Preferably, the connecting column is provided with a square groove, and the irregular steel plate has a protrusion that engages with the square groove.

[0010] Preferably, the irregularly shaped adaptable steel structure column connection structure further includes a nut, which is threadedly connected to the end of the bolt.

[0011] Preferably, the buffer pad is fixedly connected to the inner surface of the connecting plate.

[0012] Preferably, the buffer assembly further includes a base plate, and the spring is disposed between the base plate and the support plate.

[0013] Preferably, the buffer assembly further includes a second rotating rod, one end of which is rotatably connected to the support plate.

[0014] Preferably, the buffer assembly further includes a rotating rod one, which is rotatably connected to the other end of the rotating rod two, and the rotating rod one is rotatably mounted on the base plate.

[0015] Preferably, the spring, the first rotating rod, and the second rotating rod are two sets arranged symmetrically along the width direction of the support plate.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of hard impact caused by gravity during the installation and alignment of irregularly shaped steel plates in the prior art by setting a buffer assembly composed of a support plate, spring and linkage mechanism, thereby achieving the technical effects of buffer support, avoiding component damage and making the installation process safer and more convenient. 2. This utility model solves the problem in the prior art that the steel structure connection lacks lateral protection and is prone to loosening or damage due to collision after completion by setting a connecting plate with a buffer pad and using bolts and nuts to clamp it to the side of the irregular steel plate.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1 to 4 This utility model provides a connection structure for irregularly shaped steel structure columns, which aims to solve the problems of hard collision risk during the installation of irregularly shaped steel structure components and the lack of lateral collision protection after connection in the prior art.

[0021] like Figure 1 As shown, a non-standard steel structure column connection structure includes a connecting column 1 and non-standard steel plates 4 disposed between the connecting columns 1. The connecting column 1 serves as the main load-bearing and connecting body, and the non-standard steel plates 4 are the components to be connected. The structure also includes a buffer assembly 2 for supporting the non-standard steel plates 4 during installation, as well as bolts 5 and connecting plates 6 for final fastening the connection.

[0022] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific construction of the buffer component 2 and the connecting fastening structure, and the structural cooperation relationship formed between them and the connecting column 1 and the irregular steel plate 4.

[0023] Please refer to Figure 1 and Figure 2The buffer assembly 2 is disposed between the connecting columns 1 and located below the irregular steel plate 4. It is used to provide elastic support for the irregular steel plate 4 during installation. The buffer assembly 2 includes a support plate 203 that can move up and down in the vertical direction, and a spring 202 for elastically pushing the support plate 203 from below. When the irregular steel plate 4 is placed downward, its weight is borne by the support plate 203 and buffered by the compression of the spring 202, thus avoiding hard impact during installation.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4 After the irregular steel plate 4 is stably supported in the predetermined position by the buffer assembly 2, the bolts 5 are sequentially inserted into the pre-set through holes of the connecting column 1 and the irregular steel plate 4. The connecting plate 6 is sleeved on both ends of the bolts 5 and arranged on the outside of the connecting column 1. The buffer pad 7 is sandwiched between the connecting plate 6 and the side of the irregular steel plate 4. With this structure, after tightening the bolts 5, not only can a firm connection be achieved, but the buffer pad 7 can also provide continuous lateral impact protection for the irregular steel plate 4.

[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: To achieve precise positioning before installation, a square groove 3 is provided on the connecting column 1, and a protrusion that matches the shape and size of the square groove 3 is integrally formed on the irregular steel plate 4. The installation position of the irregular steel plate 4 is defined by the snap-fit ​​between the protrusion and the square groove 3.

[0026] To achieve final locking, the structure also includes a nut 8, which is threaded to the end of the bolt 5.

[0027] The buffer pad 7 is fixedly connected to the inner surface of the connecting plate 6 by adhesive bonding or vulcanization, making installation more convenient.

[0028] The buffer assembly 2 also includes a base plate 201, which serves as the mounting base for the entire assembly. The two ends of the spring 202 abut against the upper surface of the base plate 201 and the lower surface of the support plate 203, respectively.

[0029] To make the buffering movement of the support plate 203 smoother, the buffer assembly 2 also includes a linkage mechanism consisting of a second rotating rod 205 and a first rotating rod 204. One end of the second rotating rod 205 is rotatably connected to the side of the support plate 203, and one end of the first rotating rod 204 is rotatably connected to the other end of the second rotating rod 205. At the same time, the other end of the first rotating rod 204 is rotatably hinged to the base plate 201.

[0030] To achieve a balanced support effect, spring 202, rotating rod one 204 and rotating rod two 205 are arranged symmetrically in two sets along the width direction of support plate 203.

[0031] Working principle: First, the irregular steel plate 4 is clamped between the two connecting posts 1. At this time, the protruding part of the irregular steel plate 4 will be clamped in the square groove 3 on the connecting post 1. Then, the bolt 5 is inserted into the interior of the connecting post 1 and the irregular steel plate 4. At this time, the connecting plate 6 is fixed along the outer wall of the bolt 5 to both ends of the connecting post 1 for connection. At the same time, the buffer pad 7 on the connecting plate 6 can buffer and protect the irregular steel plate 4 from impact. Then, the nut 8 is tightened. At this time, the bolt 5 and the nut 8 will fix the connecting post 1 and the irregular steel plate 4, realizing a stable fixed connection of the irregular steel plate 4 and playing a role in preventing impact. During the installation of the irregular steel plate 4, the buffer assembly 2 provides buffer support. First, the irregular steel plate 4 is installed on the connecting column 1. At this time, the irregular steel plate 4 will press down on the support plate 203. The support plate 203 will then press down on the springs 202 on both sides, causing the springs 202 to deform. At the same time, the support plate 203 will press down on the rotating rod 205, causing the rotating rod 205 to open outward. This will also cause the rotating rod 204 to open outward on the base plate 201. At this time, the support plate 203 and the base plate 201 work together to provide buffer support, thus achieving the function of buffering and supporting the irregular steel plate 4 during the installation process.
