Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a steel structure connector for building exterior walls. Background Technology

[0002] Steel structure connectors are metal components used to connect the exterior wall panels of a building's steel structure to load-bearing components (such as steel columns and beams) to form a whole. They mainly bear external forces such as wind loads and seismic forces to ensure structural stability.

[0003] Existing steel structure connectors are complex in structure and poorly designed. During use, bolts and nuts are used to lock the connectors to the steel pipes and other structures. However, even after tightening, the steel pipe may still experience slight slippage within the connector, leading to positional misalignment and compromising long-term stability. The functionality of existing steel structure connectors deteriorates over time, resulting in poor practicality. Therefore, the inventors have improved the structure of the steel structure connectors. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure connector for building exterior walls. This steel structure connector has a simple structure and reasonable design, which allows multiple friction blocks to be in close contact with the surface of the steel pipe. The two generate mutual friction force, which ensures the stability of the steel pipe. With the reinforcement of bolts and nuts, it can prevent the steel pipe from experiencing slight positional displacement after long-term use, thus ensuring stability after long-term use. It also has the advantages of not decreasing functionality after repeated use, thus solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure connector for building exterior walls, comprising a connecting pipe and a connecting mechanism disposed inside the connecting pipe. The connecting pipe comprises three tubes fixed as one unit, each tube having an opening at one end and a hollow cavity structure. The openings of the cavities of the three tubes are located at their ends furthest from each other. Each of the three tubes has a sliding chamber inside. The connecting mechanism comprises a soft slider, a bladder, and a fixing plate. The bladder is disposed between the soft slider and the fixing plate. Because the bladder is slidable, it dynamically divides the sliding chamber into a first sliding groove and a second sliding groove. A spring and a connecting plate are disposed between the bladder and the fixing plate. The two ends of the spring are connected to the fixing plate and the connecting plate, respectively. A push rod is fixed at the end of the connecting plate furthest from the bladder. The push rod passes through the second sliding groove from the inside to the outside and is connected to multiple friction blocks distributed at equal intervals. The push rod slides through the fixing plate, and the fixing plate is fixed to the inner wall of the second sliding groove.

[0006] Preferably, the length directions of the three tubes are perpendicular to each other, and the three tubes are fixed together by reinforcing ribs, which strengthen the three tubes.

[0007] Preferably, a first protrusion and a second protrusion are fixed at both ends of the pipe body, respectively. A first positioning groove is provided on the first protrusion, and a second positioning groove is provided on the second protrusion. The cavity of the pipe body is used to install a steel pipe, and the first positioning groove is used to install a bolt. The bolt passes through the pipe body and is connected to a nut. The nut is set in the second positioning groove. The steel pipe is initially positioned by the cooperation of the bolt and the nut. The steel pipe is further positioned by the connecting mechanism. Multiple friction blocks on the connecting mechanism are used to contact and connect with the steel pipe and reinforce the steel pipe by sliding friction.

[0008] Preferably, the soft slider is L-shaped and is slidably disposed within the first groove.

[0009] Preferably, the bladder includes a central air bladder and pressure-bearing air bladders and compression air bladders respectively disposed at both ends of the central air bladder, wherein the pressure-bearing air bladders are connected to the soft slider and the compression air bladders are connected to the connecting plate.

[0010] Preferably, the pressure-bearing airbag is slidably disposed in the first slide groove and in contact with the inner wall of the first slide groove, the compression airbag is slidably disposed in the second slide groove and in contact with the inner wall of the second slide groove, and the central airbag is slidably disposed in the sliding chamber, so that the entire airbag can slide to a certain extent under the push of the soft slider or the connecting plate.

[0011] Preferably, multiple sets of sliding chambers and connecting mechanisms are provided, with the multiple sets of connecting mechanisms respectively located in multiple sets of sliding chambers.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a steel structure connector for building exterior walls. The connector includes a connecting pipe and a connecting mechanism disposed inside the connecting pipe. The overall structure is simple and rationally designed. The connecting pipe comprises three pipe bodies fixed as one unit. The connecting mechanism includes a soft slider, a bladder, and a fixing plate. The bladder is disposed between the soft slider and the fixing plate, dynamically dividing the sliding chamber into a first sliding groove and a second sliding groove. A spring and a connecting plate are disposed between the bladder and the fixing plate. The two ends of the spring are connected to the fixing plate and the connecting plate, respectively. The connecting plate is located away from the bladder. One end of the body is fixed with a push rod, which passes through the second sliding groove from the inside to the outside and is connected to multiple friction blocks distributed at equal intervals. In use, after the steel pipe is inserted into the tube body, it will touch the soft slider and squeeze the soft slider into the first sliding groove, which will generate pressure on the bladder. As a result, the bladder pushes the push rod with the help of the connecting plate, so that the multiple friction blocks are in close contact with the surface of the steel pipe. The two generate mutual friction force, which ensures the stability of the steel pipe. With the reinforcement of bolts and nuts, slight positional displacement of the steel pipe can be avoided after long-term use, ensuring stability after long-term use. It is suitable for widespread use.

[0014] 2. In use, when the steel pipe is removed from the tube body, the spring will drive the push rod and its multiple friction blocks back into the second slide groove, preventing it from protruding out of the second slide groove. Furthermore, the bladder will push the soft slider to protrude part of the tube body cavity, so that when a new steel pipe enters later, it can still achieve the reinforcement effect of the steel pipe, ensuring that the functionality will not decrease after repeated use, and making it highly practical.

[0026] Please see Figure 1 One embodiment of this utility model is a steel structure connector for building exterior walls, which includes a connecting pipe 1.

[0027] Please see Figure 2 The connecting pipe 1 includes three pipe bodies 11 fixed as one piece. Each of the three pipe bodies 11 is a hollow cavity structure with an opening at one end. The cavity openings of the three pipe bodies 11 are located at their ends that are far apart from each other. The length directions of the three pipe bodies 11 are perpendicular to each other. The three pipe bodies 11 are fixed together by reinforcing ribs 12, which reinforce the three pipe bodies 11. The two ends of the pipe body 11 are respectively fixed with a first protrusion 13 and a second protrusion 14. A first positioning groove 131 is provided on the first protrusion 13, and a second positioning groove 141 is provided on the second protrusion 14.

[0028] Please see Figure 3 The steel structure connectors used for the exterior walls of the building also include a connecting mechanism 2 installed inside the connecting pipe 1.

[0029] Please see Figure 4The connecting mechanism 2 includes a soft slider 21, a capsule 22 and a fixing plate 23, with the capsule 22 disposed between the soft slider 21 and the fixing plate 23.

[0030] Please see Figures 5 to 6 The cavity of the tube body 11 is used to install the steel pipe 3. The first positioning groove 131 is used to install the bolt 4. The bolt 4 passes through the tube body 11 and is connected to the nut 5. The nut 5 is set in the second positioning groove 141, so that the steel pipe 3 is initially positioned by the cooperation of the bolt 4 and the nut 5.

[0031] Please see Figure 7Each of the three tube bodies 11 has a sliding chamber inside. Multiple sets of sliding chambers and connecting mechanisms 2 are provided. Multiple sets of connecting mechanisms 2 are respectively located within multiple sets of sliding chambers. Two sets of connecting mechanisms 2 are distributed at both ends of the steel pipe 3, simultaneously supporting both ends of the steel pipe 3. This ensures that the portion of the steel pipe 3 located within the cavity of the tube body 11 remains balanced and stable at both ends. The bladder 22 is slidable, thus dynamically dividing the sliding chamber into a first sliding groove 111 and a second sliding groove 112. The soft slider 21 is L-shaped and slidably disposed within the first sliding groove 111. In this embodiment, the soft slider 21 is made of rubber and is strip-shaped. It can withstand pressure... The airbag 22 slides within the first groove 111, thereby pushing the bladder 22. A spring 24 and a connecting plate 25 are provided between the bladder 22 and the fixed plate 23. The bladder 22 includes a central airbag 221 and pressure-bearing airbags 222 and compression airbags 223 respectively disposed at both ends of the central airbag 221. The pressure-bearing airbag 222 is connected to the soft slider 21, and the compression airbag 223 is connected to the connecting plate 25. The pressure-bearing airbag 222 slides within the first groove 111 and contacts the inner wall of the first groove 111. The compression airbag 223 slides within the second groove 112 and contacts the inner wall of the second groove 112.The central airbag 221 is slidably disposed in the sliding chamber, allowing the entire airbag body 22 to slide under the push of the soft slider 21 or the connecting plate 25. The two ends of the spring 24 are connected to the fixed plate 23 and the connecting plate 25 respectively. A push rod 26 is fixed to the end of the connecting plate 25 away from the airbag body 22. The push rod 26 passes through the second sliding groove 112 from the inside to the outside and is connected to multiple equally spaced friction blocks 27, which are arranged in a straight line. The push rod 26 slides through the fixed plate 23, which is fixed to the inner wall of the second sliding groove 112. The steel pipe 3 is further positioned by the connecting mechanism 2. The multiple friction blocks 27 on the connecting mechanism 2 are used to contact and connect with the steel pipe 3, and the steel pipe 3 is reinforced by sliding friction. In this embodiment, the steel pipe 3 is used as an example, but in actual use, the steel pipe 3 can also be other types of parts. In use, the steel pipe 3 is inserted into the cavity of the tube body 11. Then, the soft slider 21 will be touched and squeezed into the first groove 111, which will exert pressure on the bladder 22. As a result, the bladder 22 will push the push rod 26 with the help of the connecting plate 25, so that multiple friction blocks 27 will be in close contact with the surface of the steel pipe 3. The two will generate mutual friction force, which will ensure the stability of the steel pipe 3. With the reinforcement of bolts 4 and nuts 5, slight positional displacement of the steel pipe 3 after long-term use can be avoided, ensuring stability after long-term use. In addition, when the steel pipe 3 is removed from the cavity of the tube body 11, the spring 24 will drive the push rod 26 and its multiple friction blocks 27 back into the second groove 112, and will not bulge out of the second groove 112. The bladder 22 will push the soft slider 21 to bulge into the cavity of the tube body 11, so that when a new steel pipe 3 is put in later, the reinforcement effect of the steel pipe 3 can still be achieved, ensuring that the functionality will not decrease after repeated use.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
