[0002] In the field of modern construction, prefabricated steel structure buildings are gradually becoming a development trend in the construction industry due to their numerous advantages, such as being green and environmentally friendly, having a fast construction speed, and being reliable in quality. In prefabricated steel structure buildings, the quality of the joint connections is a key factor determining the stability and safety of the entire building structure.

[0003] A utility model patent with patent authorization announcement number CN221721905U discloses a prefabricated lightweight steel structure, including a connecting sleeve; a convenient assembly device is installed on the connecting sleeve and the connecting sleeve; a connecting cavity is opened through the interior of the connecting sleeve and the connecting sleeve; positioning holes are opened at the four corners of the bottom end face of the inner wall of the structural groove; a connecting hole is opened through the connecting end of the lightweight steel body; a positioning rod can be inserted into the positioning hole and the connecting hole; a connecting piece is fixed to the top of the positioning rod; sliding grooves are symmetrically opened on the top of the connecting sleeve and the connecting sleeve; a first sliding ring is fitted on the outside of the cross section of one end of the connecting sleeve; a second sliding ring is fitted on the outside of the cross section of the other end of the connecting sleeve.

[0004] However, existing steel structure column joint devices also have certain shortcomings. Although existing steel structure column joint devices use fasteners such as bolts to fix and assemble steel structural components, the bolts are prone to loosening due to vibration and other external factors after long-term use. Summary of the Invention

[0005] The purpose of this utility model is to provide an easy-to-install steel structure column joint device, which solves the problem that although existing steel structure column joint devices use fasteners such as bolts to fix and assemble steel structural components, the bolts are prone to loosening due to vibration and other external factors after long-term use.

[0006] To achieve the above objectives, this utility model provides an easy-to-install steel structure column joint device, including a connector body, a first steel structure body, and a second steel structure body. The first steel structure body is located on the upper side of the connector body, and the second steel structure body is located on the lower side of the connector body. The surface of the connector body is provided with threaded holes, and a sealing gasket is fixedly sleeved on the outer side of the connector body. Fastening bolts are movably connected inside both the first and second steel structure bodies. A limit mechanism is provided on the first steel structure body, the second steel structure body, and the fastening bolts.

[0007] The principle of this utility model is as follows: by pulling the connecting frame to move away from the connecting body, the limiting rod slides along the inner wall of the fixed plate and moves the moving plate. The elastic element deforms and then pushes the first steel structure body and the second steel structure body to fit onto the outside of the connecting body, so that the sealing gasket contacts the first steel structure body and the second steel structure body. Under the action of the sealing gasket, external factors such as rainwater, dust, and moisture can be effectively prevented from entering the interior of the steel structure node, and the steel structure connection part is protected from corrosion.

[0008] By pushing the fastening bolt through the first and second steel structure bodies, the fastening bolt comes into contact with the threaded hole. Rotating the fastening bolt causes it to make threaded movement, thus installing the fastening bolt and fixing the first and second steel structure bodies. The connecting frame is then loosened to allow the elastic element to return to its original deformation, thereby pushing the limit rod into the limit hole to limit the fastening bolt and prevent it from loosening due to vibration.

[0009] By using high-strength steel for the connector body, the connector body possesses extremely high strength and good toughness, enabling it to withstand enormous tensile, compressive, and shear forces, thus ensuring a reliable connection function in the building structure.

[0010] The beneficial effects of this utility model are as follows: This solution, through the setting of the connecting body and fastening bolts, can assemble and fix the steel structure body one and steel structure body two. Under the action of the sealing gasket, it can effectively prevent external factors such as rainwater, dust, and moisture from penetrating into the interior of the steel structure node, protecting the steel structure connection parts from corrosion. Through the structure of limiting holes, limiting rods, elastic elements, etc., the fastening bolts can be limited to avoid the problem of vibration and loosening of the fastening bolts, so as to ensure the long-term stability of the steel structure node connection.

[0011] Furthermore, the connector body is integrally formed into a rectangle, and the connector body is made of high-strength steel. By using high-strength steel, the connector body has extremely high strength and good toughness, and can withstand huge tensile, compressive and shear forces, ensuring that it plays a reliable connection role in the building structure.

[0012] Furthermore, multiple threaded holes are provided, which are evenly distributed on the connector body. The presence of threaded holes facilitates installation and use with fastening bolts.

[0013] Furthermore, the sealing gasket is rectangular in shape and made of rubber. By setting the sealing gasket, it can effectively prevent external factors such as rainwater, dust, and moisture from entering the interior of the node, protect the connection from corrosion, and the rubber material has good sealing performance and aging resistance.

[0014] Furthermore, the limiting mechanism includes a limiting hole. The surface of the fastening bolt has a limiting hole. The surfaces of both the first and second steel structure bodies are fixedly connected to a fixing plate. The inner wall of the fixing plate is slidably connected to a limiting rod. The limiting rod is slidably connected to the limiting hole. A movable plate is fixedly connected to the side of the limiting rod. An elastic element is bonded to the end face of the movable plate near the fixing plate. The other end of the elastic element is bonded to the fixing plate. Through the setting of the limiting rod, limiting hole, and other structures, the fastening bolt can be inserted to avoid the problem of the fastening bolt loosening due to vibration.

[0015] Furthermore, multiple limiting holes are provided, and the multiple limiting holes are arranged in a circular array on the fastening bolt. The setting of the limiting holes facilitates the insertion and use of the limiting rod.

[0016] Furthermore, both the first and second steel structure bodies are slidably connected to a connecting frame, which is fixedly connected to a limiting rod. The connecting frame facilitates the movement of the limiting rod by pulling it. Attached Figure Description

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides an easy-to-install steel structure column node device, including a connector body 1, a first steel structure body 2, and a second steel structure body 3. The first steel structure body 2 is located on the upper side of the connector body 1, and the second steel structure body 3 is located on the lower side of the connector body 1. A threaded hole 4 is provided on the surface of the connector body 1, and a sealing gasket 5 is fixedly sleeved on the outer side of the connector body 1. Fastening bolts 6 are movably connected inside both the first steel structure body 2 and the second steel structure body 3.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the connector body 1 is integrally formed into a rectangle. The connector body 1 is made of high-strength steel. The high-strength steel gives the connector body 1 extremely high strength and good toughness, enabling it to withstand huge tensile, compressive and shear forces, ensuring a reliable connection in the building structure. Multiple threaded holes 4 are provided, which are evenly distributed on the connector body 1. The threaded holes 4 facilitate installation with fastening bolts 6. The sealing gasket 5 is integrally rectangular and made of rubber. The sealing gasket 5 effectively prevents rainwater, dust, moisture and other external factors from entering the joint, protecting the connection from corrosion. Moreover, the rubber material has good sealing performance and aging resistance.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a limiting mechanism 7 is provided on the steel structure body 1 2, the steel structure body 2 3, and the fastening bolt 6. The limiting mechanism 7 includes a limiting hole 71. The limiting hole 71 is opened on the surface of the fastening bolt 6. A fixing plate 72 is fixedly connected to the surface of both the steel structure body 1 2 and the steel structure body 2 3. A limiting rod 73 is slidably connected to the inner wall of the fixing plate 72. The limiting rod 73 is slidably connected to the limiting hole 71. A movable plate 75 is fixedly connected to the side of the limiting rod 73. An elastic element 76 is bonded to the end face of the movable plate 75 near the fixing plate 72. The other end of the elastic element 76 is bonded to the fixing plate 72. Through the setting of the limiting rod 73, the limiting hole 71, and other structures, the fastening bolt 6 can be inserted to avoid the problem of the fastening bolt 6 loosening due to vibration.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, multiple limiting holes 71 are provided, and the multiple limiting holes 71 are arranged in a ring array on the fastening bolt 6. The setting of the limiting holes 71 facilitates the insertion and use of the limiting rod 73. The surfaces of the steel structure body 1 2 and the steel structure body 2 3 are slidably connected with the connecting frame 74. The connecting frame 74 is fixedly connected to the limiting rod 73. The setting of the connecting frame 74 facilitates the movement of the limiting rod 73 by pulling it.

[0027] The specific implementation process of this utility model is as follows: By pulling the connecting frame 74 to move away from the connecting body 1, the limiting rod 73 is driven to slide along the inner wall of the fixed piece 72, and the moving piece 75 is driven to move. The elastic element 76 is deformed, and then the steel structure body 1 2 and the steel structure body 2 3 are pushed to fit on the outside of the connecting body 1, so that the sealing gasket 5 contacts the steel structure body 1 2 and the steel structure body 2 3. Under the action of the sealing gasket 5, rainwater, dust, moisture and other external factors can be effectively prevented from entering the interior of the steel structure node, and the steel structure connection part is protected from corrosion.

[0028] By pushing the fastening bolt 6 through the steel structure body 1 2 and the steel structure body 2 3, the fastening bolt 6 comes into contact with the threaded hole 4. By rotating the fastening bolt 6, the fastening bolt 6 makes threaded movement, thus installing the fastening bolt 6 and fixing the steel structure body 1 2 and the steel structure body 2 3. The connecting frame 74 is then loosened so that the elastic element 76 returns to its original deformation, thereby pushing the limiting rod 73 into the limiting hole 71 to limit the fastening bolt 6 and prevent the fastening bolt 6 from vibrating and loosening.

[0029] By using high-strength steel for the connector body 1, the connector body 1 possesses extremely high strength and good toughness, enabling it to withstand enormous tensile, compressive, and shear forces, thus ensuring a reliable connection function in the building structure.

[0030] This solution, through the installation of the connector body 1 and the fastening bolts 6, allows for the assembly and fixation of the steel structure body 1 2 and the steel structure body 2 3. With the help of the sealing gasket 5, it can effectively prevent external factors such as rainwater, dust, and moisture from penetrating into the interior of the steel structure node, protecting the steel structure connection from corrosion. Through the structure of limiting hole 71, limiting rod 73, elastic element 76, etc., the fastening bolts 6 can be limited to avoid the problem of vibration and loosening of the fastening bolts 6, so as to ensure the long-term stability of the steel structure node connection.
