Simple detection device and detection method for detecting slip resistance of scaffold right-angle coupler

Abstract

The invention discloses a simple detection device for detecting the slip resistance of a scaffold right-angle coupler, which consists of a testing device and a power loading device. A force transfer device applied onto a cross bar is arranged on the cross bar; the force transfer device is connected with the power loading device; the force transfer device consists of a top plate, two supporting dowel bars arranged between the top plate and the cross bar and force application components which are respectively arranged at the bottoms of the two supporting dowel bars and are movably connected with the cross bar. The invention also provides a method for detecting the slip resistance of the scaffold right-angle coupler. According to the invention, materials required by the simple detection device and the method are all obtained from the construction site; the simple detection device is simple to process and manufacture, has low test cost and obvious test effect and has high cost performance; the stress condition of a connecting joint of the coupler is well simulated; and by analysis on experimental data, each mechanical performance index can be well reflected. The simple detection device is simple to manufacture, is convenient to test, is easy to obtain the materials and can be manufactured by each construction organization; the quality of the coupler of the construction organization can be well controlled; and the safety of a formwork supporting system is ensured.

Description

technical field [0001] The invention belongs to the technical field of construction machinery detection equipment, and in particular relates to a test research on the anti-slip of the connecting node of the right-angle fastener to explore the factors affecting the anti-slip bearing capacity of the fastener, and to provide support for the analysis of the overall force of the formwork steel pipe support. A simple testing device and testing method for the anti-sliding performance of scaffolding right-angle fasteners that provide reference for the actual engineering formwork steel pipe support design. Background technique [0002] The fastener-type steel pipe formwork support system is one of the most common formwork support systems in my country's construction. The fastener is the main connection form of each member of the formwork support system. The force transmission between the vertical pole and the horizontal pole mainly depends on the fastener and the steel pipe. Therefore...

Problems solved by technology

[0003] At present, the anti-slip test of fasteners is mainly carried out by the anti-slip and anti-destructive performance detection device of scaffold right-angle fasteners (patent number: 200420054598). The fasteners on the construction site are comprehensively and meticulously inspected, so it is necessary to develop a lightweight, simple test device that can better simulate the stress state of the fasteners in the formwork support system to replace large-scale detection equipment
