Scaffold diagonal-bracing fastener and sliding sleeve thereof

Abstract

The invention relates to the field of scaffold fasteners, in particular to a scaffold diagonal-bracing fastener and a sliding sleeve thereof. The fastener comprises the sliding sleeve which can be sleeved on a scaffold steel tube in a sliding manner, wherein two hinged supports, which are assembled with pressure covers and hasps in a hinged way respectively, are oppositely arranged at the outer side of the sliding sleeve; the hinged axes of the hinged supports are parallel to each other and spatially crossed with the central line of the sliding sleeve; a set included angle of 30 degrees to 60 degrees is formed between the central line of the sliding sleeve and each of the hinged axes of the two hinged supports; a containing port for containing the scaffold steel tube is enclosed by the upper parts of the two hinged supports; an expansion block installation slot is enclosed by the lower parts of the two hinged supports; an opening is formed in the sleeve wall of the sliding sleeve at a position between the two hinged supports; a pressing slide block for pressing the scaffold steel tube in the sliding sleeve is assembled in the opening; and an expanding slide block which is wedged between the scaffold steel tube in the containing port and the pressing slide block is assembled in the expansion block installation slot. The scaffold diagonal-bracing fastener simultaneously has the characteristics of being convenient to operate, reliable in fixation and unlikely to lose.

Description

technical field [0001] The invention relates to the field of scaffold fasteners, in particular to a scaffold brace fastener and a sliding sleeve thereof. Background technique [0002] Fastener-type steel pipe scaffolding has been more and more widely used in construction sites due to its flexibility, reliability, and convenience. Among them, the fastener, as the connecting part between the steel pipe and the steel pipe, plays a vital role in the firmness, reliability and convenience of the scaffold. In a complete scaffolding system, fasteners are divided into butt fasteners and cross fasteners. Butt fasteners are used to butt two steel pipes, and cross fasteners are divided into cross fasteners and brace fasteners. They are both It is used to "bind" two steel pipes that intersect each other. The cross fastener is used to fix the two steel pipes that cross vertically, and the diagonal brace fastener is used between the main steel pipe and the diagonal steel pipe. Fixation b...

AI Technical Summary

Problems solved by technology

The fastener has the following problems: 1. Since the disassembly and assembly of the fastener, the base steel pipe and the diagonal steel pipe all need to knock on the corresponding buckles, it is troublesome to disassemble; Lap fit is used to fix the steel pipe, and the whole fastener does not contain other insurance measures, which makes it difficult to guarantee the reliability of the cooperation between the buckle and the gland, and it is very easy for the buckle to loosen automatically during use. Phenomenon; 3. Due to the disassembly and assembly by knocking the buckle, once the operation is wrong, the whole fastener is easy to fall, especially when the last buckle is knocked out, it is more likely to fall, which will affect the disassembly and assembly of the scaffold ;4. After the fastener is removed, it is convenient for the steel pipe to be completely separated, and it is very easy to lose it due to factors such as accidental fall. The survey shows that the loss of the fastener has become one of the most troublesome problems for the construction party.
