Scaffold screw-free right-angle coupler

Abstract

The invention discloses a scaffold screw-free right-angle coupler. The right-angle coupler includes an intermediate connecting piece; the intermediate connecting piece is connected to a first couplerbody and a second couple body; the first coupler body includes a semi-arc circle connected to the intermediate connecting piece through a pin; the semi-arc circle and the intermediate connecting pieceform an arc circle through clamping; the first coupler body also includes a fastening mechanism; the semi-arc circle can be clamped and fixed through the fastening mechanism and can form the arc circle used for fixing a scaffold with the intermediate connecting piece; and the structure of the second couple body is consistent to the structure of the first coupler body, and the second couple body and the first coupler body are in mutual dislocation with the degree of 90 degrees and respectively connected to the two sides of the intermediate connecting piece. Compared with the prior art, the right-angle coupler is fast in installation, safe and reliable, and can be freely dismounted if the right-angle coupler is corroded and rusted by long-term exposure to wind and rain and in mortar and falling products; the rejecting of the right-angle coupler can hardly happen; the right-angle coupler can be repeatedly used without soaking in oil; re-configuration of tapping and threading is not needed; maintenance costs are not needed; and the right-angle coupler is safe and fast in installation and dismounting, time-saving and labor-saving, and high in working efficiency, and has no hidden safety hazards.

Description

technical field [0001] The invention relates to the technical field of building structure construction, in particular to a screwless right-angle fastener for scaffolding. Background technique [0002] At present, the known scaffold fastener structure is to string together two arc-shaped pieces at one end by a movable pin, then string the other ends together with nails and screws, and tighten the nuts. However, the two arc-shaped pieces that are stringed together by the movable pin will be hugged by the buckled pipe, and then the other end will be tightened with a nut. This can only achieve the tightening effect based on personal feeling. There is no standard tightness, so the tightness is also different. It is easy for the buckle to slip off, which can only be tightened by a wrench round by round, not only the tightness is different, the installation speed is slow, but also the screw nuts are corroded and rusted by long-term blowing rain and mortar deposits, resulting in a l...

However, the two arc-shaped pieces that are stringed together by the movable pin will be hugged by the buckled pipe, and then the other end will be tightened with a nut. This can only achieve the tightening effect based on personal feeling. There is no standard tightness, so the tightness is also different. It is easy for the buckle to slip off, which can only be tightened by a wrench round by round, not only the tightness is different, the installation speed is slow, but also the screw nuts are corroded and rusted by long-term blowing rain and mortar deposits, resulting in a large number of Screws and nuts cannot be disassembled and can only be dismantled violently, resulting in a lot of waste and low reuse rate

Moreover, it must be soaked in oil before each use, and most of them need to be re-tapped and re-wired to configure. Not only is the maintenance cost huge, the installation is time-consuming and laborious, but it will also bring serious safety hazards to the construction and seriously threaten the personal safety of workers.
