Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to an adjustable disc buckle bracket horizontal crossbar. Background Technology
[0002] Cast-in-place box girder technology has the advantages of low cost and convenient construction, and has been widely used in bridge engineering projects. Disc-lock scaffolding improves the construction efficiency, quality and safety of cast-in-place box girders due to its high strength, high stability and rapid assembly, and is cost-effective, making it the preferred type of scaffolding for cast-in-place box girders. However, the horizontal crossbars of existing disc-lock scaffolding have fixed lengths and fixed values (60, 90, 120, 150...), while the spacing between the uprights can easily change due to various factors during on-site construction, resulting in mismatches in the horizontal members.
[0003] Therefore, it is necessary to propose an adjustable horizontal crossbar for the disc buckle bracket to solve the above problems. Utility Model Content
[0004] Technical problem to be solved: The purpose of this utility model is to provide an adjustable horizontal bar for disc buckle brackets, in order to solve the problem mentioned in the background art that the horizontal bars of existing disc buckle brackets have a fixed length and fixed value (60, 90, 120, 150...), while the spacing between the uprights is easily changed due to various factors during on-site construction, resulting in the horizontal bar not fitting properly.
[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: An adjustable disc buckle bracket horizontal crossbar includes a telescopic component, and also includes buckle connectors at both ends of the telescopic component, and pins adapted to the buckle connectors. The telescopic component includes an internally threaded tube, a rotating shaft is rotatably fitted in the middle of the internally threaded tube, and screws are threaded on both ends of the internally threaded tube, with the threads at both ends of the internally threaded tube having opposite directions. The two buckle connectors are respectively fixedly connected to the screws on adjacent sides. A sliding groove is provided axially in the middle of the screw, and a limit rod is slidably fitted in the sliding groove, with the adjacent ends of the two limit rods fixedly connected to the rotating shaft.
[0006] Preferably, the rotating shaft is integrally formed with the two limiting rods, and the limiting rods are hexagonal prisms, with the sliding grooves adapted to the limiting rods.
[0007] Preferably, both ends of the rotating shaft are concentrically fixed with limit rings, and a sleeve is fitted on the outer rotating part of the rotating shaft. The sleeve is bolted to an internally threaded pipe, and both ends of the sleeve abut against the two limit rings respectively. The outer diameter of the limit rings is larger than the inner diameter of the sleeve.
[0008] Preferably, each threaded rod between the internally threaded tube and the two threaded connectors is threaded with a nut, and the nut has the opposite thread direction to the adjacent threaded rod.
[0009] Beneficial effects: Compared with the prior art, this utility model provides an adjustable disc-lock bracket horizontal crossbar. This adjustable disc-lock bracket horizontal crossbar has a unique structure and is easy to use. During construction, one end of the buckle is first fixed to the upright connecting plate, and the internal threaded tube is rotated to move the screw away from each other until the other end of the buckle is connected to the adjacent upright connecting plate. This adapts to different upright spacings, realizes length adjustment, solves the adaptation problem caused by changes in upright spacing, and improves construction flexibility and standardization. In addition, the telescopic component is also equipped with a nut. After the crossbar is installed in place, rotating the nut abuts against the end face of the internal threaded tube to prevent vibration from causing the internal threaded tube to rotate relative to the rotating shaft, thereby enhancing the stability of the crossbar.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] Example 1: This Example 1 provides an adjustable disc buckle bracket horizontal crossbar, which is a direct improvement on the existing horizontal crossbar, with a unique structure. Please refer to [link / reference]. Figure 1-4As shown, the telescopic assembly includes a telescopic component 1, and also includes fasteners 2 disposed at both ends of the telescopic component 1, and pins 3 adapted to the fasteners 2. The telescopic component 1 includes an internally threaded tube 11, a rotating shaft 12 rotatably mounted in the middle of the internally threaded tube 11, and screws 13 threadedly mounted at both ends of the internally threaded tube 11, with the threads at both ends of the internally threaded tube 11 having opposite directions of rotation. There are various ways to install the rotating shaft 12, such as: both ends of the rotating shaft 12 are concentrically fixedly mounted with limit rings 15, and there are various ways to do so, such as: the limit rings 15 are bolted to the rotating shaft 12, and a sleeve 16 is rotatably mounted on the outside of the rotating shaft 12, and the sleeve 16 is bolted to the internally threaded tube 11. Both ends of the sleeve 16 abut against the two limit rings 15 respectively, and the outer diameter of the limit rings 15 is larger than the inner diameter of the sleeve 16. By using bolted connections, it is convenient to install and disassemble the telescopic component 1.
[0017] Two fasteners 2 are fixedly connected to the screws 13 on the adjacent sides respectively. The middle part of the screw 13 is provided with a sliding groove along the axial direction. The limiting rods 14 are slidably fitted in the sliding groove, and the adjacent ends of the two limiting rods 14 are fixedly connected to the rotating shaft 12. The rotating shaft 12 and the two limiting rods 14 are integrally formed, and the limiting rods 14 are hexagonal prisms. The sliding groove is adapted to the limiting rods 14. Through the setting of the sliding groove and the limiting rods 14, the positions of the fasteners 2 at both ends of the telescopic component 1 are kept consistent, so as to prevent the two fasteners 2 from shifting during the telescopic component 1.
[0018] Working principle: When workers use this horizontal bar, they first fix one of the buckle joints 2 to the connecting plate on the upright. Then, they rotate the internal threaded tube 11. The internal threaded tube 11 drives the two screws 13 away from each other through the threaded connection, thereby increasing the distance between the two buckle joints 2 until the other buckle joint 2 is connected to the connecting plate on the adjacent upright. Through the design of the telescopic component 1, the horizontal bar adapts to the change in the spacing between the uprights, ensuring the standardization of the construction of the disc buckle bracket and guaranteeing the integrity and safety of the disc buckle bracket.
[0019] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 1 As shown, nuts 17 are threaded onto the screws 13 between the internal threaded tube 11 and the two couplings 2, and the threads of the nuts 17 are opposite to those of the adjacent screws 13. When the two couplings 2 are mated with the connecting discs on the adjacent sides, the two nuts 17 are rotated so that they are in close contact with the end face of the internal threaded tube 11, thereby preventing vibration from causing the internal threaded tube 11 to rotate relative to the rotating shaft 12.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
