Plug-fastened self-locking exterior scaffold

Abstract

The invention relates to a card-inserting self-locking outer scaffold. The locking hook is provided on the lower end surface of the retaining column with a rotating cover corresponding to the upper end surface of the plug body, and the upper end surface of the inner ring tube of the socket is provided with two grooves along the corresponding two sides of the diameter line, and the corresponding two open outer snap rings are provided. The upper end faces of the snap rings and keys are respectively located on the outer wall of the inner ring pipe outside one end of the two lower grooves, and are on the same plane as the bottom surfaces of the two lower grooves and the other two open outer snap rings and the upper end faces of the snap keys that are equidistantly distributed. , the upper end surface of the plug body is a plane. The upper end surface of the plug body is provided with a card slot to cooperate with the locking hook on the rotating cover to tighten the plug. The present invention can form a completely closed and locked plug, pressing and pulling, increasing safety and reliability, enabling the plug to be completely fixed on the socket, and using a limit ring to complete the pressing and pulling of the plug to completely close and lock it. And the outward force of the cross bar transmits the pulling force to the column through the plug, so that the scaffold does not shake and is solid and stable.

Description

technical field [0001] The invention relates to a scaffold for building construction, in particular to a card-inserting self-locking outer scaffold. Background technique [0002] The support systems and scaffolds commonly used in building construction include fastener steel pipe type, multifunctional door frame type, adjustable independent steel pillar type, bowl buckle type support system or scaffolding; there are also square wood as force bearing Supporting system; use aluminum wire to bind moso bamboo or logs as a supporting system or scaffolding. These support systems or scaffolds have many disadvantages. Some consume a large amount of raw materials and have low efficacy. Some fasteners require workers to carry and install them, which is labor-intensive, time-consuming, and easy to lose. Damage, some of which have poor stress effects, and the operation process is not easy to control, which brings certain hidden dangers to construction safety. For this reason, the inven...

Problems solved by technology

However, this design can only press the plug into the socket in fact, and cannot form a completely closed lock on the plug, press, and pull in the socket. If the plug is applied outward or to both sides, the plug will Unable to transmit the pulling force, the light one will cause the scaffold to shake and become unstable, and the heavy one will damage the plug or break away from the socket, causing hidden accidents

On the other hand, the structural design of this design is unreasonable, not only troublesome, high cost, but also too heavy, laborious construction, difficult to assemble and disassemble during the construction process, assembly and disassembly can easily cause damage to the plug and socket, and shorten the service life. short
