Description

Technical Field

[0001] The utility model relates to the technical field of building construction scaffolds, in particular to a steel pipe fastener with a new structural form which can fasten three steel pipes at the same time. Background Art

[0002] Steel pipe fasteners generally refer to the intermediate connectors that connect two components. In construction projects, they are mostly used to fix steel pipe scaffolding with an outer diameter of 48 mm. Currently, common fasteners are divided into right-angle fasteners (cross fasteners and directional fasteners), rotating fasteners (movable fasteners and universal fasteners), butt fasteners (straight fasteners and direct fasteners), etc.

[0003] Chinese patent publication number CN212507338U discloses a new type of steel pipe fastener. By placing a first stopper outside the clamp, the exposed screw is modified to an internal one. This avoids the problems of existing steel pipe fasteners with exposed screws, which make it difficult to seal iron sheets and hanging cloths, easily accumulate steel grit particles, and difficult to disassemble. During use, the screw core is not exposed, and the first and second connecting parts are detachably connected. This also increases the contact surface between the first and second connecting bodies. This increases the stability and firmness of the steel pipe fastener while making it reusable, reducing costs and losses, and minimizing safety hazards. It can replace welding and is suitable for use in wall construction, fence advertising, welded billboards, various types of racks, small-scale farm buildings, temporary housing, and other applications. It has a wide range of applications and a long service life. However, existing steel pipe fasteners can only secure a single steel pipe, which reduces the stability of the entire structure and is prone to tilting or deformation under high stress. Furthermore, under wind pressure, a single fixed steel pipe cannot effectively withstand wind pressure, increasing the risk of structural collapse. Utility Model Content
