Abstract

The invention discloses a quick-locking fastener unit, a combined fastener, a tie rod and a portal frame. The fastener comprises a hinge pin, a wedge block for locking, a first semicircular clamp and a second semicircular clamp. When the wedge block is locked, two locking work faces of the wedge blocks are located on the two sides of a common plane of the fastener unit correspondingly. The common plane is formed by two parallel axes, and the two parallel axes refer to the axis of the hinge pin and the axis of the inner arc surface in the first semicircular clamp correspondingly. The combined fastener is composed of two fastener units. The tie rod comprises a tie rod main body and fastener units at the two ends, and the axis of the tie rod main body is located in symmetrical planes of the fastener units. The portal frame comprises a portal frame main body and fastener units located at the four corners, wherein the portal frame main body is formed by welding steel pipes, and the four symmetrical planes of the four fastener units overlap. The quick-locking fastener unit, the combined fastener, the tie rod and the portal frame have the beneficial effects that the quick-locking fastener unit, the combined fastener, the tie rod and the portal frame are of the same fastener structure, and locking is reliable; and when the quick-locking fastener unit, the combined fastener, the tie rod and the portal frame are used for assembling and disassembling a supporting system, the stability of the system is good, potential safety hazards are few, the assembling and disassembling efficiency is high, and the construction cost is low.

Description

technical field [0001] The invention relates to a connecting member for erecting a building construction scaffolding or formwork support system, in particular to a fast locking fastener unit, a combined fastener, a tie rod and a door frame. Background technique [0002] During the building construction process, it is necessary to set up scaffolding and formwork support systems. In order to meet the requirements of modern construction, the scaffolding or supporting system not only needs to have sufficient safety guarantee, but also requires higher and higher erection efficiency. At present, there are two commonly used erection methods, one is erected through grid frames, and the other is erected through standpipes plus horizontal pipes or diagonal bracing pipes. The installation of the net frame requires a height-adjustable bowl seat under the net frame, and the net frame is large in size, and the transportation of the net frame is extremely inconvenient, the transportation ...
