Description

Technical Field

[0001] This application relates to the field of building steel structure technology, specifically a protective device for high-rise building steel structures. Background Technology

[0002] High-rise steel structures typically refer to the structures of tall buildings. These structures are mainly made of steel profiles and plates connected or welded into steel components, which are then connected and welded together to form a structural system. The steel structure includes steel components such as steel pipes.

[0003] Currently, in the process of connecting and installing steel pipes in high-rise buildings, the steel pipes are generally held stably by a clamping mechanism to facilitate subsequent connection and installation operations (thereby ensuring the safety and protection of the steel pipes). However, the connection and installation of steel pipes may be carried out in a high-vibration operating environment. If the handle in the clamping mechanism is accidentally touched, the clamping plate holding the steel pipe may easily loosen, making it difficult to achieve a safe clamping and protection effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a protective device for steel structures of high-rise buildings to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a protective device for steel structures of high-rise buildings, including a base. A groove is provided on the inner side of the base. A guide rod is fixedly connected to the inner side of the base. An inner trapezoidal clamping plate is slidably connected to the outer surface of the guide rod. A rubber pad is provided on the inner side of the inner trapezoidal clamping plate. A screw is rotatably connected to the inner surface of the base, and the outer surface of the screw is threadedly engaged with the inner surface of the inner trapezoidal clamping plate. A self-locking mechanism is provided on the screw. The outer surface of the screw has threads of the same length but opposite directions from the middle to both ends. Rotation of the screw causes the two sets of inner trapezoidal clamping plates to move closer or further apart.

[0006] Preferably, a spring is provided on the inner side of the inner trapezoidal clamp, and a steel pipe is detachably installed on the base. The spring is movably sleeved around the guide rod and the screw.

[0007] Preferably, the self-locking mechanism includes a handle fixedly connected to one end of the screw, and a ratchet is fixedly sleeved on the outer surface of the screw. The self-locking mechanism can stably clamp the screw inside the steel pipe and limit its position, thus preventing the clamp from loosening when the handle is accidentally touched in a high-vibration environment.

[0008] Preferably, a first fixed shaft is fixedly connected to the outer surface of the base, and a pawl is rotatably connected to the outer surface of the first fixed shaft.

[0009] Preferably, a second fixed shaft is fixedly connected to the outer surface of the base, and a spring lever is provided on the second fixed shaft.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This protective device for high-rise building steel structures effectively prevents the clamping mechanism from loosening under high vibration or misoperation environments by introducing a self-locking drive mechanism, namely a combination of pawl and ratchet. Even if the handle is accidentally touched during construction, the screw will not rotate arbitrarily due to the stabilizing and limiting effect of the pawl, thus ensuring the stable clamping of the steel pipe and greatly reducing the risk of safety accidents.

[0012] 2. This protective device for high-rise building steel structures uses two sets of inner trapezoidal clamps that move closer together under the drive of screws. Springs ensure stable clamping of the steel pipe, and rubber pads provide a soft and uniform contact surface for the steel pipe during clamping, effectively avoiding scratches or damage that may be caused by direct metal contact and protecting the surface quality of the steel pipe. This design not only ensures the uniform distribution of clamping force but also reduces the impact on the steel pipe during clamping, thus improving the overall protective performance of the structure.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] Please see Figure 1-2A protective device for steel structures of high-rise buildings includes a base 1, a groove 2 on the inner side of the base 1, a guide rod 3 fixedly connected to the inner side of the base 1, an inner trapezoidal clamping plate 4 slidably connected to the outer surface of the guide rod 3, a rubber pad 5 provided on the inner side of the inner trapezoidal clamping plate 4, a screw 8 rotatably connected to the inner surface of the base 1, and the outer surface of the screw 8 threadedly sleeved with the inner surface of the inner trapezoidal clamping plate 4, and a drive self-locking mechanism provided on the screw 8.

[0018] With the above technical solution, when the device is in use, the rotating handle 9 drives the screw 8 to rotate. Under the relative limiting action of the guide rod 3, the two sets of inner trapezoidal clamps 4 move closer to each other to clamp the steel pipe 7. With the help of the drive self-locking mechanism, the screw 8 can be kept in a locked state after stable clamping to prevent the clamping from loosening.

[0019] Specifically, a spring 6 is provided on the inner side of the inner trapezoidal clamp 4, and a steel pipe 7 is detachably installed on the base 1.

[0020] Through the above technical solution, the two sets of inner trapezoidal clamps 4 will compress the spring 6 when they approach each other. During this process, the relative buffering effect of the spring 6 can be used to avoid the instantaneous direct clamping and squeezing of the steel pipe 7, thus achieving a certain protective effect.

[0021] Specifically, the self-locking mechanism includes a handle 9 fixedly connected to one end of the screw 8, and a ratchet 10 fixedly sleeved on the outer surface of the screw 8.

[0022] With the above technical solution, before rotating the screw 8, the pawl 12 needs to be moved away from the ratchet 10, otherwise the screw 8 will be difficult to rotate smoothly.

[0023] Specifically, a first fixed shaft 11 is fixedly connected to the outer surface of the base 1, and a pawl 12 is rotatably connected to the outer surface of the first fixed shaft 11.

[0024] With the above technical solution, under normal conditions, the tip of the pawl 12 is stuck between the teeth of the ratchet 10, and with the help of the spring pawl 14, the pawl 12 can be in a relatively stable state.

[0025] Specifically, a second fixed shaft 13 is fixedly connected to the outer surface of the base 1, and a spring lever 14 is provided on the second fixed shaft 13.

[0026] Through the above technical solution, the spring pawl 14 has excellent elastic deformation capability. It relies on the pawl 12, which can make it rotate along the first fixed axis 11 and finally lock onto the ratchet 10, effectively limiting its movement.

[0027] Working Principle: During the connection and installation of steel pipe 7 on high-rise buildings, the steel pipe 7 is generally stably clamped by a clamping mechanism. Considering that the connection and installation of steel pipe 7 may be carried out in a high-vibration operating environment, if the handle 9 in the clamping mechanism is accidentally touched, the clamping of steel pipe 7 may become loose. Therefore, a drive self-locking mechanism is designed. That is, when clamping and stabilizing steel pipe 7, the pawl 12 must first be moved to rotate along the first fixed axis 11. During this process, the spring pawl 14 will be pushed and its position will be offset until the tip of the pawl 12 is no longer stuck between the teeth of the ratchet 10. Then, the handle 9 can be turned to drive the screw 8 to rotate. During the rotation of the screw 8, the relative limiting of the inner trapezoidal clamping plate 4 by the guide rod 3 can make the two sets of inner Trapezoidal clamping plates 4 approach each other within the slide groove 2. During this process, spring 6 is gradually compressed until the two sets of inner trapezoidal clamping plates 4 stably clamp the steel pipe 7. In this process, spring 6 can buffer and release the instantaneous clamping collision force of the two sets of inner trapezoidal clamping plates 4 on the steel pipe 7. Together with the rubber pad 5 on the inner side of the inner trapezoidal clamping plate 4, it can provide a good protective effect during the stable clamping of the steel pipe 7. After the steel pipe 7 is stably clamped, the pawl 12 can be released, allowing it to rotate along the first fixed axis 11 under the elastic action of the spring pawl 14, and finally stably jammed between the teeth of the ratchet 10, thereby stably limiting the screw 8. At this time, even if the handle 9 is accidentally touched in a high vibration environment, the screw 8 will not be able to rotate smoothly, thus playing an excellent protective role in the stable clamping of the steel pipe 7.

[0028] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
