There are three kinds of coupler products: right-angle coupler, docking coupler, rotating coupler. Packed in woven bag, 3 bkyniqo2ner1 each bag is 25.The weight of each should be 1.1 KG (including bolt and nut).In general is to use the form of a dip in the red anti-rust paint do antirust processing. And frame tube. General production and the ratio of purchasing is 8:1:1 coupler products. Say is right Angle in proportion accounted for 80%, 10%, docking rotating 10%.

Coupler type steel scaffolding tube is composed of steel tube pipe and coupler, with the features of easy processing, handling bento, versatility, such as characteristics, has become a time using the biggest and the most widely used in our country a scaffolding, scaffolding using total accounted for about 70%.

The advantages and disadvantages of coupler type steel pipe scaffolding tube strengths: bento installation, erection of loose, large bearing capacity, the erection of high altitude, durable, turns, processing a brief, more disadvantages: low cost of a capital contribution buckle easily lose, big differences in the bolt tightening, offset or intersection distance between nodes in the force corresponding to use: scaffold, brace. The role of scaffolding is generally accumulated material, workers work station.

Of coupler type steel pipe scaffold: steel pipes, coupler, base and plate, scaffolding, safety net coupler made of malleable cast iron or cast steel. Divided into: right-angle coupler, inversion of coupler (rotating coupler), docking coupler.

Coupler scaffold is the most used scaffolding, scaffolding disturbance rate accounted for 11.86% of engineering trouble rate, die gap below small make up analyses 10 coupler scaffold attack the cause of the trouble, construction personnel, please remember that! Field due to the strict control of the percent of pass, the standard rules JGJ130-2011 docking coupler against sliding bearing capacity is 3.2 KN, the orthogonal inversion coupler against sliding bearing capacity is 8 KN, and the scene - ~ is very difficult to achieve this rule.
