Technical Field

[0001] This utility model belongs to the field of steel structure technology, specifically relating to a reusable building steel structure connector. Background Technology

[0002] Steel structure connectors are metal parts used to connect steel structure components or parts, mainly for connecting steel components, wood components, and components made of both steel and wood. Common steel structure connectors include rivets, bolts, high-strength bolts, and welding rods.

[0003] However, existing steel structure connectors often use a large number of bolts for fixing, or bolts combined with welding for fixing. Fixing is time-consuming and labor-intensive, and it is not easy to disassemble or reuse, resulting in waste. Therefore, there is an urgent need for a reusable steel structure connector to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a reusable building steel structure connector, so as to solve the problem mentioned in the background art that existing steel structure connectors often use a large number of bolts for fixing, or bolts combined with welding for fixing, which is time-consuming and laborious, and inconvenient to disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reusable building steel structure connector, comprising a steel structure one, a steel structure two, a support structure, a plug rod, a limiting rod one, a connecting plate, and a fixing structure. The support structure includes a limiting plate, with fixing plates fixedly connected to both the front and rear sides of the limiting plate. The upper and lower ends of the fixing plate are fixedly connected to the steel structure one by fixing bolts one. The limiting plate is slidably connected to the plug rod, with limiting rod one fixedly connected to both the upper and lower sides of the plug rod. The plug rod and limiting rod one are slidably connected to the steel structure one. Both limiting rods one are slidably connected to the steel structure two. Two connecting plates are fixedly connected to the side of the limiting rod one furthest from the middle. The fixing structure includes a threaded rod, with the connecting plate threadedly connected to the threaded rod. The bottom end of the threaded rod is rotatably connected to a clamping plate.

[0006] Preferably, the insertion rod is T-shaped, with a limiting plate slidably connected to the left end of the insertion rod, and a steel structure and a fixing plate slidably connected to the right end of the insertion rod.

[0007] Preferably, the left end of the limiting rod is slidably connected to the steel structure, and the right end of the limiting rod is provided with a slot.

[0008] Preferably, the connecting plates at both ends are fixedly connected by two fixing bolts.

[0009] Preferably, a handle is fixedly connected to the top of the threaded rod. The handle is a hexagonal handle and has an anti-slip coating on its surface.

[0010] Preferably, a rubber pad is fixedly connected to the side of the clamp near the middle, and the surface of the rubber pad is provided with an uneven pattern.

[0011] Preferably, the left and right ends of the clamping plate away from the middle are fixedly connected to the second limiting rod, and the second limiting rod is slidably connected to the first limiting rod.

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

[0013] 1. This reusable building steel structure connector includes insert rods, limiting rod 1, and connecting plates. A fixing plate is secured to the front and rear ends of a steel structure 1 using fixing bolt 1. Two insert rods and limiting rod 1 are inserted into the limiting plate and the front and rear ends of the steel structure 1. The limiting plate supports the insert rods. Two connecting plates are secured using fixing bolt 2, fixing the positions of the insert rods and limiting rod 1. A steel structure 2 is inserted into the limiting rod 1, with both its upper and lower ends inserted into the slots. The insert rods, limiting rod 1, and connecting plates support the steel structure 2. Installation and disassembly are convenient and quick, facilitating repeated use.

[0014] 2. This reusable building steel structure connector is equipped with a fixing structure. When the second steel structure is inserted into the first limiting rod, the top of the second steel structure rests against the inner wall of the top slot. Rotating the handle causes the handle to rotate the threaded rod, which moves downward, causing the threaded rod to move the clamping plate downward, so that the clamping plate rests against the surface of the second steel structure. The rubber pad increases the friction between the clamping plate and the surface of the second steel structure, improving the stability during clamping. First, rotating the top handle clamps the second steel structure with the clamping plate and the limiting rod, and then rotating the bottom handle supports the second steel structure with the clamping plate. The fixing structure can fix and support the second steel structure, and can clamp steel beams of different sizes within the bearing range, improving applicability and ease of use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a reusable building steel structure connector, comprising a steel structure 1, a steel structure 2, a support structure 3, a plug rod 4, a limiting rod 5, a connecting plate 6, and a fixing structure 7. The support structure 3 includes a limiting plate 31, with fixing plates 32 fixedly connected to both the front and rear sides of the limiting plate 31. The upper and lower ends of the fixing plate 32 are fixedly connected to the steel structure 1 by fixing bolts 33. The limiting plate 31 is slidably connected to the plug rod 4, with limiting rods 5 fixedly connected to both the upper and lower sides of the plug rod 4. The plug rod 4 and the limiting rod 5 are slidably connected to the steel structure 1. The first structure 1 has two limiting rods 5 that are slidably connected to the second steel structure 2. The limiting rods 5 are fixedly connected to two connecting plates 6 on the side away from the middle. The fixing structure 7 includes a threaded rod 71. The connecting plates 6 are threadedly connected to the threaded rod 71. The bottom end of the threaded rod 71 is rotatably connected to the clamping plate 73. The second steel structure 2 is supported by the insert rod 4, the limiting rods 5, and the connecting plates 6. It is easy and quick to install and disassemble, and is easy to reuse. The fixing structure 7 can fix and support the second steel structure 2, and can clamp steel beams of different sizes within the bearing range, which improves its applicability and ease of use.

[0023] Furthermore, the insertion rod 4 is T-shaped, with the left end of the insertion rod 4 slidably connected to the limiting plate 31, and the right end of the insertion rod 4 slidably connected to the steel structure 1 and the fixing plate 32. The two insertion rods 4 and the limiting rod 5 are inserted into the limiting plate 31 and the front and rear ends of the steel structure 1, and the insertion rod 4 is supported by the limiting plate 31.

[0024] Furthermore, the left end of the limiting rod 1 5 is slidably connected to the steel structure 1, and the right end of the limiting rod 1 5 is provided with a slot 51. The steel structure 2 is inserted into the limiting rod 1 5, so that both the upper and lower ends of the steel structure 2 are inserted into the slot 51. When the steel structure 2 is inserted into the limiting rod 1 5, the top end of the steel structure 2 abuts against the inner wall of the top slot 51. The connecting plates 6 at the front and rear ends are fixedly connected by fixing bolts 2 61. The two connecting plates 6 are fixed by fixing bolts 2 61, so that the positions of the insert rod 4 and the limiting rod 1 5 are fixed.

[0025] Furthermore, a handle 72 is fixedly connected to the top of the threaded rod 71. The handle 72 is a hexagonal handle with an anti-slip coating on its surface. The anti-slip coating prevents slippage when rotating the handle 72, and the hexagonal handle is easier to hold.

[0026] Furthermore, a rubber pad 74 is fixedly connected to the side of the clamping plate 73 near the middle. The surface of the rubber pad 74 is provided with uneven patterns. The rubber pad 74 can increase the friction between the clamping plate 73 and the steel structure 2. The uneven surface can increase the contact area between the rubber pad 74 and the steel structure 2, thereby improving the stability during clamping.

[0027] Furthermore, the left and right ends of the side of the clamping plate 73 away from the middle are fixedly connected to the second limiting rod 75. The second limiting rod 75 is slidably connected to the first limiting rod 5. The second limiting rod 75 prevents the clamping plate 73 from rotating when it moves up and down, thus playing a limiting role.

[0028] Working principle: In use, the fixing plate 32 is fixed to the front and rear ends of the steel structure 1 using fixing bolt 33. Two insert rods 4 and limiting rod 5 are inserted into the limiting plate 31 and the front and rear ends of the steel structure 1. The limiting plate 31 supports the insert rods 4. The two connecting plates 6 are fixed using fixing bolt 61, fixing the positions of the insert rods 4 and the limiting rod 5. The steel structure 2 is then inserted into the limiting rod 5, with both its upper and lower ends inserted into the slots 51. The insert rods 4, limiting rod 5, and connecting plate 6 support the steel structure 2. Installation and disassembly are convenient and quick, facilitating reuse. When the steel structure 2 is inserted into the limiting rod 5, its top end abuts against... On the inner wall of the top slot 51, rotate the handle 72 to drive the threaded rod 71 to rotate, causing the threaded rod 71 to move downwards. This causes the clamping plate 73 to move downwards, so that the clamping plate 73 abuts against the surface of the steel structure 2. The rubber pad 74 increases the friction between the clamping plate 73 and the surface of the steel structure 2, improving the stability during clamping. First, rotate the top handle 72 to clamp the steel structure 2 with the clamping plate 73 and the limiting rod 5. Then, rotate the bottom handle 72 to support the steel structure 2 with the clamping plate 73. The fixing structure 7 can fix and support the steel structure 2, and clamp steel beams of different sizes within the bearing range, improving applicability and ease of use.
