Description

Technical Field

[0001] This utility model relates to the field of scaffolding structure technology, specifically to a high-load disc-lock scaffolding crossbar. Background Technology

[0002] The core function of the horizontal bar in a disc-lock scaffold is to connect the vertical poles and maintain the overall stability of the scaffold. It is usually a single-member structure, with both ends connected to discs on the vertical poles via couplings to form horizontal supports. It mainly bears horizontal loads and can meet the usage requirements under normal loads.

[0003] However, if the crossbar is subjected to significant vertical loads not intended for design purposes during actual use, such as when construction workers directly pile heavy objects on it or use it as a material transfer platform, the stress state of the crossbar will fundamentally change. This additional concentrated or uniformly distributed vertical load significantly increases the bending moment at the mid-span of the crossbar and the stress strength at both ends of the joints. Given that the crossbar's cross-sectional dimensions and material specifications are not designed for this type of vertical load, it is highly susceptible to excessive deflection and structural deformation in the mid-span area. In severe cases, this can even lead to crossbar bending instability, joint connection failure, or connection breakdown, thereby jeopardizing the structural stability and construction safety of the entire scaffolding system. Therefore, a high-load-bearing disc-lock scaffolding crossbar is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-load disc-lock scaffold crossbar to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-load disc-lock scaffold crossbar includes a crossbar with two support rods at its bottom. Each support rod has a fastener at one end. The fastener includes a first snap-fit ​​and a second snap-fit. The second snap-fit ​​has a limiting hole and a limiting groove. The first snap-fit ​​includes two bent portions. The fastener also includes a threaded rod with a limiting head at one end. One bent portion of the first snap-fit ​​overlaps with the limiting head, and the other bent portion is inserted into the limiting hole. The threaded rod is inserted into the limiting groove. The threaded rod has two possible structures. Firstly, a locking bolt is provided on the outside, and the locking bolt is located on one side of the limiting groove; Secondly, a fixing hole is provided on one side of the threaded rod, and a pin is inserted into the fixing hole.

[0006] Preferably, the structure includes two uprights, with the crossbar located between the two uprights. The crossbar has fasteners at both ends, which are fastened to the uprights.

[0007] Preferably, the fastener is provided with a snap-fit ​​groove and a pin hole, and a pin is inserted into the pin hole.

[0008] Preferably, the outside of the upright is provided with equally spaced discs, the fastener engages with the discs, and the discs are inserted into the inside of the engaging groove.

[0009] Preferably, the disc is provided with a plurality of connecting holes, and the pin is inserted into the interior of the connecting holes.

[0010] Preferably, the crossbar, support bar, and upright bar form a right-angled triangular structure through fasteners and fastener connectors.

[0011] In the above technical solution, the present invention provides a high-load disc-lock scaffold crossbar, (1) by setting up a connection node for the crossbar, the bearing capacity of the crossbar node can be directly improved, and the original force structure is changed. The force in the middle of the span is reduced. The crossbar, support bar, and upright form a right triangle structure through fasteners and fastener joints. Not only can the stability of the triangle be used to strengthen the scaffold, but also the shaking between the scaffold bodies can be reduced, which has a good stabilizing effect; (2) by setting up a variety of connection methods, the construction worker has more choices according to the environment and location, which is convenient for the construction worker to operate.
