Multi-direction centralized connection type composed scaffold

Abstract

The invention relates to a multidirectional concentration connection and combination type scaffold for solving the problems of too many components of the prior scaffold and difficulty of dismantling the components of the prior scaffold. The scaffold consists of a hack lever and a fastener used for the connection of the hack lever. The fastener includes a joint fastener sleeved with the ends of two standing hack levers and a not-joint fastener sleeved at the external periphery of the standing hack levers; an inner convex ring corresponding to the ends of the standing hack levers is arranged inthe middle of internal periphery of the head joint fastener; two to three layers of prick ears are arranged at the external periphery of the joint fastener and the non-joint fastener for the connection of diagonal hack levers and horizontal hack levers, the number of each layer of prick ears is four, and the prick ears are in the cross distribution; horizontal ears are arranged at the external periphery of the joint fastener and the non-joint fastener between two layers of prick ears for the connection of the horizontal hack levers, the number of each layer of horizontal ears is four and the horizontal ears are in cross distribution, and are distributed at the angle of 45 DEG in the circumferential direction and between the prick ears; pin holes are formed in the prick ears and the horizontal ears, ear grooves matched with the prick ears and the horizontal ears are arranged at the ends of the diagonal hack levers and the horizontal hack levers so as to be matched with the pin holes. Pin holes are formed are formed on groove walls on two sides of the ear grooves, and inner screw threads are arranged in pin holes on the groove wall on the side and pins with outer screw threads beingat one end. The invention has the advantages of less connection pieces, convenient disassembly and assembly and strong reliability.

Description

technical field [0001] The invention relates to a construction scaffold, in particular to a multi-directional centralized connection type combined scaffold. Background technique [0002] Existing combined scaffolding is all formed by the frame bar and the fastener that connects the frame bar. Usually, one fastener can only connect two frame rods. When multiple frame rods need to be connected at the same time, multiple fasteners must be installed in a small space, which not only wastes fasteners, but also wastes disassembly and assembly man-hours; and because it is A plurality of fasteners are connected indirectly, with many connection links and poor reliability. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and provide a multi-directional centralized connection combined scaffold with less connectors, convenient assembly and disassembly, and high reliability. [0004] In order to achiev...
