Bowl-Coupler Steel Tube Scaffold Joint Erection Technology

Bowl-Coupler Steel Tube Scaffold Joint Erection Technology

(1) Before erecting the scaffold, a scaffold construction organization design shall be prepared. The applied loads shall be clarified, the plan and elevation layout of the scaffold shall be determined, a component quantity list shall be prepared, and a component supply and turnover plan shall be formulated, etc.

(2) All components must be inspected and repaired to be qualified before being put into use. https://www.xghsbzl.com

(3) The construction of the upright foundation shall meet the requirements. Debris within the erection area shall be cleared, the site shall be leveled, and drainage shall be properly handled.

(4) Joint erection:

1) The joint is the connecting device between the upright and the horizontal tube and diagonal tube, and the joint must be locked securely. During erection, first place the upper bowl coupler on the limit pin, insert the joints of the horizontal tube and diagonal tube into the lower bowl coupler, so that the arc surface of the joint fits tightly against the upright. After all joints are inserted, lower the upper bowl coupler and tap the convex head of the upper bowl coupler clockwise along the tangent with a hammer until the upper bowl coupler is clamped by the limit pin and no longer rotates.

2) If the upper bowl coupler cannot be tightened, or the limit pin cannot enter the spiral surface of the upper bowl coupler, check whether the upright and horizontal tube are vertical, whether two adjacent bowl couplers are on the same horizontal plane (i.e., whether the horizontality of the horizontal tube meets the requirements); whether the coaxiality of the lower bowl coupler and the upright meets the requirements; whether the perpendicularity of the horizontal plane of the lower bowl coupler to the axis of the upright meets the requirements; whether the horizontal tube joint and the horizontal tube are deformed; whether the center line of the arc surface of the horizontal tube joint is perpendicular to the axis of the horizontal tube; whether there is mortar or other debris filling the lower bowl coupler, etc. If it is due to assembly reasons, adjust and lock; if it is due to the component itself, remove it and send it for repair.

How did the bowl-coupler scaffold develop?

　The origin of scaffolding is very early. Since ancient Chinese architecture began, scaffolding has been put into use, but at that time the scaffolding was relatively simple, mainly composed of wooden boards and wooden sticks. For example, scaffolding was used in the construction of ancient Chinese pagodas, city walls, buildings, Buddhist halls, and other structures. Bowl-coupler scaffold components have uniform dimensions, and the erected scaffold has the characteristics of normalization and standardization, suitable for civilized on-site construction; because the bowl coupler and the component are integrated, the cost of loss and wear of scattered parts is avoided, facilitating on-site management.

　　Currently used steel tube scaffolds include coupler-type steel tube scaffolds, bowl-coupler steel tube scaffolds, socket-type steel tube scaffolds, portal scaffolds, as well as various interior scaffolds, suspended cantilever scaffolds, and other steel tube scaffolds.

  The bowl-coupler scaffold reduces labor intensity, has high assembly and disassembly efficiency, and high work intensity. The joint assembly and disassembly speed is 2-3 times faster than conventional scaffolds. Workers only need a small iron hammer to complete all operations, which can reduce labor intensity by 0.5 times. Cost reduction: bowl-coupler scaffold manufacturers can use existing coupler-type steel tube scaffolds for equipment modification, greatly reducing renewal costs.
