Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a connection structure between a prefabricated composite insulated exterior wall panel and a steel beam. Background Technology

[0002] Prefabricated composite insulated exterior wall panels are a new type of building exterior wall material that integrates insulation and structural functions. They are prefabricated in factories and assembled on-site, offering advantages such as high efficiency, energy saving, and environmental protection. As a key component of the enclosure structure, the efficient connection technology between prefabricated composite insulated exterior wall panels and steel beams has become a core bottleneck restricting the promotion of prefabricated steel structure buildings.

[0003] Traditional connection methods often use bolts for fixing. Under stress, this type of fixing can cause the bolts to loosen and rotate, leading to instability in the fixing position, gaps between the wall panel and the steel beam, and other problems that affect the stability of the structure. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam, which solves the problem mentioned in the background art that when bolt connections are subjected to stress, the bolts may rotate and loosen, resulting in instability in the fixed position, gaps between the wall panel and the steel beam, and affecting the stability of the structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam, comprising a wall panel body and a fixing frame, wherein fixing bolts are threadedly connected to the four corner edges of the surface of the fixing frame, and vertical plates are fixedly connected to both sides of the surface of the fixing frame, wherein a sliding rod is slidably connected through the side wall of the vertical plate, and a locking block and a pressing block are fixedly connected to both ends of the sliding rod, wherein the pressing block contacts the nut of the main bolt, and a rotating frame is rotatably connected to the top of the main bolt.

[0006] In this technical solution, a fixing frame is set on the outside of the main bolt. The fixing frame itself can provide secondary reinforcement to the steel beam and wall panel. Furthermore, the pressure blocks on both sides of its surface will limit and clamp the main bolt from both sides under the clamping and squeezing action of the rotating frame. The rotating frame will also clamp and limit the clamping blocks, which improves the stability of the main bolt and makes the wall panel and steel beam fit tightly together.

[0007] Preferably, the fixing bolt passes through the surface of the fixing frame and is threadedly connected to both the wall panel body and the steel beam body, and a central hole is provided in the center of the surface of the fixing frame.

[0008] Preferably, both the wall panel body and the steel beam body have connection holes of the same size on their surfaces, the inner walls of the connection holes have threaded grooves, and the inner sides of the connection holes are threaded with main bolts.

[0009] Preferably, the front and rear inner sidewalls of the bottom of the rotating frame are provided with slots, and the size of the slots is the same as the size of the card blocks.

[0010] Preferably, the bottom of the main bolt has a threaded hole, and a limit bolt is threadedly connected to the surface of the steel beam body corresponding to the horizontal position of the threaded hole. One end of the limit bolt penetrates the surface of the steel beam body and is threadedly connected to the inside of the threaded hole.

[0011] Preferably, the fixing bracket is located on the surface of the wall panel body, and the main bolt passes through the central hole and contacts the fixing bracket.

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

[0013] 1. This utility model provides a fixing frame on the outside of the main bolt. The fixing frame itself can provide secondary reinforcement to the steel beam and wall panel. Furthermore, the pressure blocks on both sides of its surface will limit and clamp the main bolt from both sides under the clamping and squeezing action of the rotating frame. The rotating frame will also clamp and limit the clamping blocks, thereby improving the stability of the main bolt and ensuring that the wall panel and steel beam fit together tightly.

[0014] 2. This utility model provides a threaded hole at the bottom of the main bolt. After the main bolt is fully screwed into the connecting hole, a limiting bolt is screwed into the threaded hole, thereby reinforcing the connection between the steel beam body and the main bolt and further improving the stability of the connection.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0023] A connection structure between a prefabricated composite insulated exterior wall panel and a steel beam, see [reference needed]. Figures 1 to 5 The system includes a wall panel body 1 and a fixing frame 3. The fixing frame 3 is located on the surface of the wall panel body 1. Each of the four corner edges of the surface of the fixing frame 3 is threaded with a fixing bolt 301. The fixing bolt 301 passes through the surface of the fixing frame 3 and is threadedly connected to both the wall panel body 1 and the steel beam body 2. A central hole 302 is provided in the center of the surface of the fixing frame 3. Before installing the main bolt 6, the fixing frame 3 is installed on the outside of the connecting hole 101 and the fixing bolt 301 is screwed in. After passing through the fixing frame 3, the fixing bolt 301 passes through the wall panel body 1 and finally enters the steel beam body 2, thus connecting with the fixing frame 3, the wall panel body 1 and the steel beam body 2 simultaneously, thereby providing secondary reinforcement to the wall panel body 1 and the steel beam body 2 and improving the stability.

[0024] Specifically, such as Figure 3 As shown, vertical plates 4 are fixedly connected to both sides of the surface of the fixing frame 3. A sliding rod 5 is slidably connected through the side wall of the vertical plate 4. A locking block 501 and a pressing block 502 are fixedly connected to both ends of the sliding rod 5, respectively. The pressing block 502 contacts the nut of the main bolt 6. A rotating frame 7 is rotatably connected to the top of the main bolt 6. The front and rear inner side walls of the bottom of the rotating frame 7 are provided with locking grooves 701. After the fixing frame 3 is installed, the main bolt 6 is screwed into the connecting hole 101. Pressing the main bolt 6 against the surface of the fixed frame 3, the sliding rod 5 slides, allowing the pressure block 502 to clamp the main bolt 6 from both sides. Then, the rotating frame 7 is rotated. The slot 701 of the rotating frame 7 is the same size as the pressure block 501. When rotating the pressure block 501, force is applied to continue rotating, so that the slot 701 locks the pressure block 501, thereby limiting the sliding rod 5 and the pressure block 502. The pressure block 502 is tightly attached to the main bolt 6, thereby limiting the rotation of the main bolt 6 and preventing the main bolt 6 from rotating, thus improving the stability of the main bolt 6.

[0025] Furthermore, such as Figure 4 and Figure 5As shown, a screw hole 601 is provided at the bottom of the main bolt 6. A limit bolt 8 is threadedly connected to the surface of the steel beam body 2 corresponding to the horizontal position of the screw hole 601. One end of the limit bolt 8 penetrates the surface of the steel beam body 2 and is threaded to the inside of the screw hole 601. After the main bolt 6 is fully screwed in, the limit bolt 8 is screwed into the hole reserved on the surface of the steel beam on the other side. One end of the limit bolt 8 is screwed into the screw hole 601, thereby further limiting the main bolt 6 and further connecting the steel beam and the main bolt 6 together, improving the stability of the overall structure.

[0026] It is worth noting that, such as Figure 5 As shown, both the wall panel body 1 and the steel beam body 2 have connection holes 101 of the same size on their surfaces. The inner wall of the connection hole 101 has a threaded groove, and the inner side of the connection hole 101 is threaded with a main bolt 6. The main bolt 6 passes through the central hole 302 and contacts the fixing frame 3. During installation, the connection holes 101 of the wall panel body 1 and the steel beam body 2 need to be aligned, and then the main bolt 6 is screwed in for fixation. After the main bolt 6 is tightened, it will press tightly against the fixing frame 3, which indirectly plays a role in fixing the fixing frame 3.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
