Double tube aluminum pole machine connection
[China Aluminum Network] Double-pipe aluminum pole machine adopts the arrangement of lower double-pole poles and upper single-pipe expansion poles. It is a common method to solve the ultra-high problems of scaffolding in the construction practice. Because of its convenient installation, direct measures, and low cost, this method is widely used and has a good effect.
1. Double-bar aluminum pole machine system Large crossbar load-bearing type: Small crossbar is connected with the right angle fasteners and the two large crossbars, both sides of the big crossbar are using right angle fasteners and double pipe aluminum pole machine Root extension joint.
Crossbar mixing weight: The internal large and small crossbars are connected with right angle fasteners (or swivel fasteners). The small crossbar uses right angle fasteners and one of the double tube poles (connected uprights are called The "main pole" and the other is called the "sub-pole" are connected. Both sides of the big crossbar are connected by two vertical rods of the double-bar t-bar.
2. The connection between the upper single pole and the double-pipe pole is butt-joint type: the single-spread pole and the double-pipe pole are connected with the docking fastener.
Overlapping type: The two vertical poles of the upper single fire pole and the lower double pipe pole are overlapped with no less than three rotary fasteners. The bottom of the single aluminum alloy pole machine shall be supported on the small crossbar and then be erected. There are two fasteners (attached to the pole, with right-angled fasteners or rotating fasteners) under the connecting fasteners of the rod-and-bar crossbars, and the folk fasteners should be tightly attached to reinforce the support of the large crossbar.
