Description

Technical Field

[0001] This utility model relates to a scaffolding connection and reinforcement device. Background Technology

[0002] In construction projects, scaffolding reinforcement on building facades typically employs scissor bracing. Existing scissor bracing consists of two intersecting support pipes, each made up of two overlapping steel pipes. Standards require an overlap length of at least 1 meter, with the two pipes secured by three couplers. This long overlap reduces the available length for connecting the non-overlapping ends, hindering subsequent construction. Furthermore, strict requirements are placed on coupler quality and installation techniques. Using inferior couplers or improper tightening can easily lead to insufficient stress on the scissor bracing, failing to achieve its intended function. Moreover, most existing scaffolding uprights and horizontal members use KZФ48A butt couplers. While this type of coupler is inexpensive, its smaller load-bearing capacity and poor bending resistance can cause uneven stress on the uprights, ultimately resulting in significant tilting of the exterior scaffolding. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a low-cost scaffolding connection and reinforcement device that ensures stable connections while improving construction efficiency.

[0004] To achieve the above objectives, this utility model first proposes a scaffolding connection and reinforcement device, including two reinforcement pipes with inner diameters matching the outer diameters of the scaffolding steel pipes. The two reinforcement pipes are coaxially arranged, and the opposite ends of the two reinforcement pipes are connected and fixed by a baffle. The baffle closes the opposite ends of the reinforcement pipes, and the inner cavities of the two reinforcement pipes form insertion holes for inserting scaffolding steel pipes on both sides of the baffle.

[0005] In this embodiment, the baffle is a circular baffle with a diameter matching the outer diameter of the reinforcing tube, so that the baffle does not protrude from the outer side of the reinforcing tube.

[0006] In this embodiment, the reinforcing pipe is a steel pipe with a wall thickness of 3.6mm and a material of Q235, and the length of the reinforcing pipe is 30cm.

[0007] In this embodiment, the baffle is a steel plate with a thickness of 1 cm.

[0008] In this embodiment, the reinforcing pipe and the baffle are fixed by welding.

[0009] In this embodiment, the side wall of the reinforcing pipe is also provided with a pin hole, and the side wall of the insertion end of the scaffolding steel pipe is provided with a through hole corresponding to the pin hole on the reinforcing pipe. After the scaffolding steel pipe is inserted into the reinforcing pipe and installed in place, the relative positions of the scaffolding steel pipe and the reinforcing pipe are fixed by the pins inserted in the pin hole and the through hole.

[0010] In this embodiment, a buffer layer is also fixed inside the reinforcing tube and on the baffle.

[0011] In this embodiment, the reinforcing pipe has a chamfer on the inner wall of the inlet end of the insertion hole to facilitate the insertion of scaffolding steel pipes.

[0012] With the above structure, this utility model has the following advantages:

[0013] 1. This device consists of two reinforcing pipes with inner diameters matching the outer diameter of the scaffolding steel pipes, and a baffle connecting the two reinforcing pipes. When used for scaffolding scissor bracing, this device can quickly connect two scaffolding steel pipes to form a support pipe. It is easy to operate, greatly improves construction efficiency, and does not occupy the length of the scaffolding steel pipes, facilitating subsequent connections of the scaffolding steel pipes. Furthermore, it does not require additional fasteners, saving construction costs.

[0014] 2. This device has a chamfer on the inner wall of the inlet end of the reinforcing pipe insertion hole, which makes the insertion of scaffolding steel pipes more accurate and efficient, reducing the time and difficulty of alignment and insertion.

[0015] 3. The pin holes on the side wall of the reinforcing pipe and the corresponding through holes on the side wall of the scaffolding steel pipe greatly enhance the stability of the connection between the scaffolding steel pipe and the reinforcing pipe after the pins are inserted, effectively preventing loosening or detachment during use.

[0016] 4. The buffer layer fixed on the inner baffle of the reinforced pipe plays an important role. On the one hand, it significantly reduces the collision and wear between the scaffolding steel pipe and the baffle when it is inserted, thus extending the service life of the entire device. On the other hand, it effectively reduces the collision noise during insertion, achieving a silent effect and improving the construction environment.

[0017] In summary, this utility model can ensure the stress strength of scaffold connections, reduce the overlap length of scaffold scissor bracing steel pipes, increase the fixed length of scaffold uprights and horizontal bars, and is easy to construct without the need for additional fasteners. The final product has a good appearance. At the same time, the process of this utility model is simple and quick to construct, which can effectively save a series of costs such as manpower, material resources, and construction time occupied by traditional scaffold connection methods.

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] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] like Figure 1 , 2 As shown, a scaffolding connection and reinforcement device includes two reinforcement pipes 4 with inner diameters matching the outer diameter of the scaffolding steel pipe 1. The two reinforcement pipes 4 are coaxially arranged, and their opposite ends are connected and fixed by a baffle 3. The diameter of the baffle 3 matches the outer diameter of the reinforcement pipe 4. In this embodiment, the reinforcement pipe 4 is a steel pipe with a wall thickness of 3.6mm and a material of Q235. The inner diameter of the reinforcement pipe 4 is 50mm, and the length of the reinforcement pipe 4 is 30cm. The baffle is a steel plate with a thickness of 1cm. Furthermore, the reinforcement pipe 4 and the baffle are fixed by welding. The inner cavities of the two reinforcement pipes 4 form insertion holes for inserting the scaffolding steel pipe 1 on both sides of the baffle. The outer diameter of the scaffolding steel pipe 1 is generally 48.3mm, which is slightly smaller than the size of the insertion holes.

[0024] When this device is used for scaffolding scissor bracing, first install the lower scaffolding steel pipe 1, then insert one end of this device into the scaffolding steel pipe 1, and then insert the upper scaffolding steel pipe 1 into the other end of this device, thus realizing the support pipe that originally required two steel pipes to overlap to form; then continue the above operation to install the support pipe on the other side, and finally use swivel couplers to further reinforce and connect the two support pipes; the operation is the same when connecting and reinforcing scaffolding uprights or horizontal bars.

[0025] like Figure 2As shown, the reinforcing pipe 4 has a chamfer 41 on the inner wall of the inlet end of the insertion hole to facilitate the insertion of the scaffolding steel pipe 1. The chamfer 41 is preferably 45°, which improves the accuracy and efficiency of the connection between the scaffolding steel pipe 1 and the reinforcing pipe 4. The side wall of the reinforcing pipe 4 is also provided with a pin hole 42, the diameter of which is preferably 10mm. The side wall of the insertion end of the scaffolding steel pipe 1 is provided with a through hole corresponding to the pin hole 42 on the reinforcing pipe 4. After the scaffolding steel pipe 1 is inserted into the reinforcing pipe 4 and is in place, the pin 2 inserted in the pin hole 42 and the through hole further strengthens the stability of the connection between the scaffolding steel pipe 1 and the reinforcing pipe 4. A buffer layer 5 is also fixed inside the reinforcing pipe 4 and on the baffle. The buffer layer 5 can reduce the collision and wear between the scaffolding steel pipe 1 and the baffle when the scaffolding steel pipe 1 is inserted into the reinforcing pipe 4, thereby improving the service life of the entire device. At the same time, it can also reduce the collision noise when the scaffolding steel pipe 1 is inserted into the reinforcing pipe 4, achieving a silent effect.
