Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and in particular relates to a building steel structure connector. Background Technology

[0002] Steel structure houses use profiled steel instead of traditional reinforced concrete, offering advantages such as rapid construction, light weight, high strength, and good seismic performance, making them a highly efficient and energy-saving green building type. However, during construction, connectors are needed to join the steel structure. Traditional connectors are mostly L-shaped with non-adjustable angles, which cannot meet the connection needs of steel structures at different angles in practical use.

[0003] Utility model patent application number 202222652113.2 discloses a connector for assembling steel structure houses. It connects a first connector and a second connector by setting a smooth rod, a threaded cylinder, and a screw, allowing for angle adjustment between the two connectors and enabling the assembly of steel structures at different angles. Because the threaded sleeve and screw are connected by relative rotation, and the angle between the threaded sleeve or screw and the connector changes after rotation, the connection between the threaded sleeve or screw and the connector should have 360° freedom. The attached drawings show that the threaded sleeve or screw and the connector are connected by a universal ball joint. However, this universal ball joint connection is difficult to disassemble, and it is not easy to replace the threaded cylinder and screw after damage. Furthermore, the connector cannot be disassembled during transportation, occupying space. Utility Model Content

[0026] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0027] like Figures 1-2 The illustrated steel structure connector for a building includes: a first fastener 1, a second fastener 2, a connecting shaft 3, and a supporting device. In this embodiment, both the first fastener 1 and the second fastener 2 are U-shaped, including a vertical portion 17 and two horizontal portions 18. More specifically, the first fastener 1 and the second fastener 2 are made of steel. The connecting shaft 3 passes through one end of the first fastener 1 and the second fastener 2 and is rotatably connected to the first fastener 1 and the second fastener 2, as shown. Figure 1As shown, the connecting shaft 3 passes downward through the horizontal part 18 of the fixing part 1 and the fixing part 2, that is, the fixing part 1 and the fixing part 2 are hinged by the connecting shaft 3; furthermore, the middle part of the connecting shaft 3 is smooth and the two ends are provided with external threads, and the external threads are engaged with nuts 19. During transportation, nuts 19 can be unscrewed to separate the fixing part 1, the fixing part 2 and the connecting shaft 3, saving space.

[0028] The support device is detachably connected to the opposite side of the fixing member 1 and the fixing member 2. Specifically, the inner walls of the vertical portions 17 of the fixing member 1 and the fixing member 2 are opposite to each other, and the support device is detachably connected between the inner walls of the two vertical portions 17. The support device is used to fix and support the relative position between the fixing member 1 and the fixing member 2, adapting to the connection of steel structures at different angles. Both the fixing member 1 and the fixing member 2 are provided with a plurality of connecting holes 4, which are respectively arranged on the vertical portions 17 and the horizontal portions 18 of the fixing member 1 and the fixing member 2. In this embodiment, the support device is located near the connecting shaft 3, and the connecting holes 4 are located on the fixing members on the outside of the support device. Specifically, two rows of connecting holes 4 are provided on both the vertical portions 17 and the horizontal portions 18. When connected to the steel structure, the steel structure can be installed inside or outside the fixing member, depending on the actual needs.

[0029] In this device, the support device and fixing components 1 and 2 are detachably connected. When the support device is damaged, it is easy to replace. Furthermore, the connecting components can be disassembled into individual parts during transportation, saving space. In addition, when disassembled into individual fixing components, the fixing components can also connect and assemble two straight-connected steel sections. Further, fixing components 1 and 2 are respectively provided with ear plates 5 and 6 on opposite sides. Both ear plates 5 and 6 have through holes 7 in their middle portions. The structure of the fixing components is as follows... Figure 2 As shown, the ear plate is welded to the fixing member; the two ends of the support device are detachably connected to the through holes 7 on the ear plate 1 5 and the ear plate 2 6 respectively.

[0030] The connection methods between the support device and the fastener include, but are not limited to, the following two.

[0031] In the first method, both ends of the support device are connected to the through hole 7 via engaging bolts and nuts. Specifically, connecting blocks 9 are provided at both ends of the support device, and the connecting blocks 9 are fixedly connected to the ear plate via bolts and nuts. Figure 1 , Figures 4-6 As shown. In the second type, the support device has hooks 8 at both ends, which are inserted downwards into the through holes 7, as shown. Figure 3As shown, the hook head 8 is in close contact with the inner wall of the through hole 7 to prevent the fixing part 1 and the fixing part 2 from rotating relative to each other during support.

[0032] In one possible implementation, the support device can be configured as a rigid component. During use, the relative positions of fixing component 1 and fixing component 2 are first adjusted, and then a support device of appropriate length is installed between fixing component 1 and fixing component 2 according to the adjusted position. In another possible implementation, the support device is telescopic. During use, the relative positions of fixing component 1 and fixing component 2, as well as the length of the support device, can be adjusted first before installing the support device with the fixing components; alternatively, the support device can be installed with fixing component 1 and fixing component 2 first, and then the length of the support device can be adjusted to adjust the relative positions of fixing component 1 and fixing component 2.

[0033] When the support device is telescopic, the support device includes a first connecting section 10, a sliding sleeve 11, a second connecting section 12, and a fixing mechanism. The first connecting section 10 and the second connecting section 12 are respectively slidably disposed at both ends inside the sliding sleeve 11 and are fixedly connected to the sliding sleeve 11 through the fixing mechanism. The free end of the first connecting section 10 is detachably connected to the first fixing member 1, and the free end of the second connecting section 12 is detachably connected to the second fixing member 2. The connection method between the first connecting section 10, the second connecting section 12, and the first fixing member 1 and the second fixing member 2 is the same as the connection method between the support device and the fixing member described above, that is, the ends of the first connecting section 10 and the second connecting section 12 are respectively provided with connecting blocks 9 and / or hooks 8, and the first fixing member 1 and the second fixing member 2 are provided with ear plates with through holes 7.

[0034] The structural forms of fixed mechanisms include, but are not limited to, the following two.

[0035] The first type, such as Figure 5 As shown, the first connecting section 10 and the second connecting section 12 are rod-shaped; the fixing mechanism includes an external thread 13 on the outer wall of the first connecting section 10, an external thread 14 on the outer wall of the second connecting section 12, and internal threads 1 and 2 respectively on the inner wall of the sliding sleeve 11, which mesh with the external threads 13 and 14; the external threads 13 and 14 have opposite directions of rotation. When the sliding sleeve 11 is turned, the connecting sections 10 and 12 move closer or further apart under the action of the threads, adjusting the length of the support device.

[0036] The second type, such as Figure 6As shown, the fixing mechanism includes a fixing groove 15 on the outer wall of the first connecting section 10, a fixing groove 2 on the outer wall of the second connecting section 12, screw holes 16 at both ends of the sliding sleeve 11, and a set screw. Each end of the sliding sleeve 11 has at least one screw hole 16. The fixing groove 15 and the fixing groove 2 extend along the length of the first connecting section 10 and the second connecting section 12, respectively. The fixing groove 15 and the fixing groove 2 correspond to the screw holes 16 at both ends of the sliding sleeve 11 and are connected by the set screw. Tightening the set screw into the screw hole 16, with the bottom of the set screw pressing against the fixing groove, secures the support device.
