Description

Technical Field

[0001] The present application belongs to the technical field of testing devices, and specifically relates to a scaffold fastener mechanical performance testing device. Background Art

[0002] Scaffolding fasteners are key components used to connect two steel pipes (usually vertical poles, horizontal poles, or diagonal poles) in building scaffolding systems. Their core function is to secure the steel pipes into a stable frame structure through a detachable connection method to carry construction loads and ensure operational safety. From a structural perspective, common scaffolding fasteners are mostly made of cast iron or steel, and mainly include right-angle fasteners (for connecting vertically intersecting steel pipes), rotating fasteners (for connecting steel pipes that intersect at a certain angle), and butt fasteners (for connecting two steel pipes in the same direction). Their working principle is to tighten the cover plate and base by bolts, utilizing the friction and mechanical locking effect between the two to clamp and fix the steel pipes, achieving a rigid or semi-rigid connection between the steel pipes. In the prior art, scaffolding fasteners are the core components for connecting steel pipes in building scaffolding systems. Their mechanical properties (such as anti-slip performance, anti-destruction performance, torsional stiffness, etc.) directly determine the overall stability and construction safety of the scaffolding. Therefore, conducting accurate mechanical property tests on them is a key link in ensuring construction safety.

[0003] At present, the scaffolding fastener mechanical properties testing devices on the market have certain limitations in practical applications. The clamp structure used to fix the steel pipe in some devices lacks flexibility in position and angle adjustment, making it difficult to adapt to the appearance characteristics of steel pipes of different specifications, resulting in poor fit between the clamp and the steel pipe and low positioning accuracy. As a result, the pressure applied by the hydraulic rod cannot accurately act on the connection between the fastener and the steel pipe, which can easily cause test force transmission deviation and affect the accuracy of the test data. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The angle and position of the U-shaped clamp can be finely adjusted by bolt three and the rotating shaft to ensure that it fits tightly with the steel pipe and is precisely aligned, so that the pressure applied by the hydraulic rod can accurately act on the fastener connection part; and the base position is adjusted by slide groove one and bolt one, and the position of the mounting seat (i.e., hydraulic rod) is adjusted by slide groove two and bolt two, so that the pressure applied by the hydraulic rod can act on different positions of the scaffolding fastener.
