Double-pole scaffold system

Abstract

The invention relates to the field of building scaffolds, and in particular relates to a double-pole scaffold system. The system comprises vertical rods and horizontal rods, wherein cross-shaped buckling parts are arranged at positions of the corresponding cross-shaped joints on the vertical rods; the cross-shaped buckling parts comprise sliding sleeves sleeved on the vertical rods and pressing assemblies arranged on the sliding sleeves; each pressing assembly comprises two hinge seats; one of the two hinge seats is hinged with a pressing cover, the other one of the two hinge seats is hinged with a hasp; hinging axial lines of the two hinge seats are parallel to each other and are vertically crossed with a space of central lines of the sliding sleeves; and in addition, a containing opening for containing the corresponding horizontal rods is encircled between the upper parts of the two hinge seats; an expansion block mounting groove is encircled between the lower parts of the two hinge seats; openings, of which the inner parts and the outer parts penetrate through each other, are formed between the two hinge seats of each set of pressing assembly on the walls of the sliding sleeves; an expanding sliding block which is used for preventing falling and wedged between the vertical rods and the corresponding horizontal rods is arranged in the expanding block mounting groove; and the double-pole scaffold system has the characteristic of convenience in application, and the security performance of a scaffold is improved.

Description

technical field [0001] The invention relates to the field of building scaffolding, in particular to a double-row scaffolding system. Background technique [0002] At present, the common scaffolds in the construction field are divided into fastener-type steel pipe scaffolding, bowl buckle-type steel pipe scaffolding, socket-type steel pipe scaffolding, door-type scaffolding, and various scaffolding, hanging scaffolding and other steel pipe material scaffolding . Among them, the double-row scaffolding system is a kind of fastener-type steel pipe scaffolding. [0003] The double-row scaffolding system includes an inner row of vertical poles, two outer rows of vertical poles, and vertical and horizontal horizontal poles, which form a cross-shaped node or cross each other to form a space node. The double-row scaffolding system is generally used in masonry projects, which require load-bearing, cement, transfer and other building materials. Therefore, it is required that there m...

Problems solved by technology

It can be seen from its working principle that the above-mentioned cross fastener needs to operate at least two glands separately when in use, that is, the upper gland and the side gland, so the efficiency is low. In addition, because the gland base of the above-mentioned fastener is in operation It is fixed by connecting bolts, which further reduces the work efficiency of the staff, that is, reduces the efficiency of scaffolding construction and disassembly, and increases the labor intensity of the staff. It is especially worth noting that the working environment of fasteners is mostly relatively harsh. , once the connecting bolts are rusted or stained, it will further cause inconvenience to the disassembly of the fastener, which in essence also affects the service life of the fastener and increases its maintenance cost; moreover, the above fastener can only be used Realize the binding connection between two intersecting scaffold steel pipes (longitudinal and horizontal horizontal bars, intersecting vertical bars and longitudinal horizontal bars or intersecting vertical bars and horizontal horizontal bars), which also reduces to a certain extent Improve the efficiency of erecting and dismantling double-row scaffolding

[0004] In order to solve the problem of inconvenient disassembly and assembly caused by the connecting bolts of the fasteners, the Chinese patents with the application number 2012202780806 and the application number 932388701 respectively disclose two kinds of scaffold fasteners fixed by wedges. A wedge is set between the outer surface of the fastener gland and the nut of the connecting bolt to tighten and fix the gland. In this case, the connecting bolt actually forms a buckle, which only needs to be turned in during use. The bayonet of the corresponding gland can be tightened with wedges, thereby eliminating the need to tighten and loosen the nuts of the connecting bolts, which brings benefits to the improvement of construction efficiency to a certain extent, but the above fasteners It is still necessary to operate two sets of glands, connecting bolts and corresponding wedges separately, and there is still the problem of inconvenient operation. In addition, because the wedge is located between the gland and the gland of the connecting bolts, it is very easy to be misplaced on the one hand. There is a certain potential safety hazard, and on the other hand, it also makes the loss of wedges an inevitable problem.
