Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to an adjustable scissor brace device. Background Technology

[0002] External scaffolding is widely used on construction sites for safety protection during the construction process. The most common types are steel pipe coupler scaffolding and disc-lock scaffolding. After the scaffolding reaches a certain height, scissor bracing should be installed to enhance the stability and overall integrity of the structure.

[0003] However, in actual construction, diagonal bracing is often used to cross and overlap between scissor bracing. Since diagonal bracing is usually a hollow steel pipe with a certain diameter, the two diagonal bracings are located on different planes after crossing. This will cause the gap between the outer diagonal bracing and the outer scaffold upright to be too large, making it difficult for the diagonal bracing to establish a reliable connection with the upright on the scaffold. This fails to meet the specifications and poses a significant safety hazard.

[0004] Therefore, it is necessary to study an adjustable scissor brace device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an adjustable scissor bracing device, which can effectively solve the problem that the gap between the outer diagonal brace and the upright of the scaffold is too large, making it difficult for the diagonal brace to establish a reliable connection with the upright.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adjustable scissor brace device includes a cross member, a socket, a diagonal brace, and a first collar;

[0008] The cross member is flat and there are two sets of cross members. The two sets of cross members are arranged crosswise and rotatably connected at the cross center.

[0009] The socket cylinder is provided in four sets. The socket cylinder includes an integrated fixing part and a socket part. Each set of cross parts has a corresponding socket cylinder fixed at both ends.

[0010] The outer surface of the socket is provided with external threads, and the socket is a hollow structure to form a socket cavity for the insertion of the diagonal brace.

[0011] The socket has multiple long openings extending along its length, dividing it into at least two segments.

[0012] The diameter of the diagonal brace is larger than the inner diameter of the socket cavity. When the diagonal brace is inserted into the socket cavity, the long opening of the socket is opened.

[0013] The socket is threadedly fitted with a first collar for bringing the long opening together to clamp the socket tightly to the diagonal brace.

[0014] Furthermore, the first collar is located at the end of the socket near the fixing part.

[0015] Furthermore, an elastic hook is provided at the end of the socket portion away from the fixing portion, and the elastic hook is evenly fixed to the inner surface of the socket portion around its circumference.

[0016] When the diagonal brace is inserted into the socket, the elastic hook presses against the diagonal brace.

[0017] Furthermore, it also includes a second ring, the inner diameter of which is larger than that of the first ring, and is threaded to the end of the socket that is away from the fixed part. The second ring causes the end of the socket that is away from the fixed part to close up and the elastic hook to press against the diagonal brace.

[0018] Furthermore, the cross member includes a central disc portion and connecting portions symmetrically connected to both sides of the disc. The disc portion is evenly provided with several limiting holes around the center. The two disc portions are overlapped and rotatably connected at the center. Limiting pins are correspondingly inserted and connected in the limiting holes of the two disc portions.

[0019] Furthermore, the side end face of the fixing part is provided with a slot adapted to the connecting part, and the connecting part is inserted into and fixed in the slot.

[0020] The beneficial effects of the above technical solution are:

[0021] (1) In this utility model, the cross member is flat and there are two sets. The two sets of cross members are arranged crosswise and rotated and connected at the center of the cross. The thickness of the flat cross members stacked together is less than the thickness of the two steel pipes overlapping, so that the gap between the diagonal bar on the outside and the upright on the scaffold is smaller, thereby satisfying the requirement that the scissor brace is effectively connected to each adjacent upright, and increasing the rigidity of the scaffold.

[0022] (2) The cross member of this utility model includes a central disc portion and connecting portions symmetrically connected to both sides of the disc. The two sets of cross members are rotatably connected at the cross center by a rotating shaft, so that the angle of the scissor brace can be adjusted around the center point. The disc portion is evenly provided with several limiting holes around the center. Limiting pins are correspondingly connected through the limiting holes of the two disc portions. At least one set of limiting pins is required to limit the rotation of the two cross members after the angle adjustment is completed, so as to convert the rotation into a rigid connection and improve the structural strength.

[0023] (3) The socket of this utility model has two long openings extending along the length of the socket in the circumferential direction, which divide the socket into two halves. The first ring is used to clamp the socket onto the diagonal support rod, so as to realize the connection between the socket and the diagonal support rod. When in use, it can be disassembled by simply loosening the ring, without the need for tools or hole positioning. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0031] This embodiment aims to provide an adjustable scissor bracing device, which is mainly used to reinforce and support scaffolding. It addresses the problem that the gap between the outer diagonal brace and the upright of the scaffolding is too large, making it difficult for the diagonal brace to establish a reliable connection with the upright.

[0032] An adjustable scissor brace device, such as Figure 1 surround Figure 2 The system includes a cross member 1, a socket tube 2, a diagonal brace 3, and a first ring 4. The cross member 1 is flat and consists of two sets, which are arranged crosswise and rotatably connected at the center of the cross. The thickness of the flat cross member 1, with the cross plates 1 stacked together, is less than the thickness of the two steel pipes overlapping, making the gap between the outer diagonal brace and the uprights on the scaffold smaller. This ensures effective connection between the scissor brace and each adjacent upright, increasing the rigidity of the scaffold.

[0033] The cross member 1 includes a central disc portion 101 and connecting portions 102 symmetrically connected to both sides of the disc. Two sets of cross members 1 are rotatably connected at the center of the intersection via a rotating shaft, allowing the scissor brace to be angled around the center point. In this embodiment, the disc portion 101 has eight evenly spaced limiting holes 103 around its center. The two disc portions 101 overlap and are rotatably connected at their center. Limiting pins 104 are correspondingly inserted into the limiting holes 103 of the two disc portions 101. At least one set of limiting pins 104 is required to restrict the rotation of the two cross members 1 after angle adjustment, transforming the rotatable connection into a rigid connection to improve structural strength. In other embodiments, the limiting holes 103 and limiting pins 104 may be omitted to maintain the rotatable connection of the two cross members 1 at all times.

[0034] The socket cylinder 2 is provided with four sets. The socket cylinder 2 includes an integrally formed fixing part 201 and a socket part 202. The four sets of fixing parts 201 are respectively fixedly connected to the ends of two sets of intersecting parts 1. Specifically, as shown in the figure... Figure 4 The side end face of the fixing part 201 is provided with a slot 204 that is adapted to the connecting part 102. The width of the connecting part 102 is greater than the width of the slot 204. The connecting part 102 is inserted into and welded to the slot 204.

[0035] like Figure 3 and Figure 4 The outer surface of the socket portion 202 is provided with external threads. The socket portion 202 is a hollow tube structure with a cylindrical socket cavity. The socket portion 202 has two long openings 203 extending along its length direction, dividing the socket portion 202 into two halves. In other embodiments, it can also be divided into four or six halves. The socket portion 202 is a thin metal tube, and after being divided by the long openings 203, it exhibits the ability to elastically expand along the axis.

[0036] The diagonal brace 3 is a conventional steel pipe. The diameter of the diagonal brace 3 is larger than the inner diameter of the socket cavity. When the diagonal brace 3 is inserted into the socket 202, it can open the long opening 203, so that the bearing part is a cone shape with the opening gradually increasing outward, and the outward direction is away from the cross member 1.

[0037] The first set of rings 4 is located at one end of the socket 202 near the fixing part 201. When the diagonal brace 3 is not inserted into the socket cavity, the first set of rings 4 naturally fits onto the socket 202. After the diagonal brace 3 is inserted into the socket cavity, the first set of rings 4 is rotated outward, so that the first set of rings 4 is threaded onto the socket cylinder 2. As it rotates outward, since the socket 202 is expanded into a conical shape, the threaded engagement between the first set of rings 4 and the socket 202 will gradually tighten, and the long opening 203 will gradually converge slightly to clamp the socket 202 onto the diagonal brace 3, thus achieving the connection between the socket cylinder 2 and the diagonal brace 3. During use, it can be disassembled simply by loosening the rings, without the need for tools or hole positioning.

[0038] Considering that the first ring 4 only secures the end of the socket 202 closest to the fixing part 201, while a gap remains at the end of the socket 202 away from the fixing part 201, no actual connection is formed. Therefore, as... Figure 4 and Figure 5 An elastic hook 5 is provided at the end of the socket 202 away from the fixed part 201. The elastic hook 5 is uniformly welded and fixed to the inner surface of the socket 202. When the diagonal support rod 3 is inserted into the socket 202, the elastic hook 5 presses on the diagonal support rod 3, which can fill the gap at the end of the socket 202 away from the fixed part 201. The friction between the elastic hook 5 and the support rod can prevent the diagonal support rod 3 from detaching from the socket cavity.

[0039] like Figure 3 and Figure 4 It also includes a second ring 6, the inner diameter of which is larger than that of the second ring 6. The second ring 6 is fitted onto the socket 202. After the diagonal brace 3 is inserted into the socket cavity, its principle is the same as that of the first ring 4. The second ring 6 is rotated outward so that the second ring 6 is threaded onto the end of the socket 202 away from the fixed part 201. The second ring 6 causes the end of the socket 202 away from the fixed part 201 to be gathered and the elastic hook 5 to be pressed against the diagonal brace 3, so that the end of the socket 202 away from the fixed part 201 is fixedly connected to the support rod.
