What is the spacing of the members of the aluminum scaffolding and the scissors support

Apr 25, 2019

When aluminum scaffolding is constructed, the spacing between the poles, large crossbars and small crossbars shall comply with the specifications and construction requirements. When it is necessary to increase the spacing at the door, etc., the poles should be reinforced according to the specifications. It is the main force member of aluminum scaffolding. The spacing should be evenly set. The spacing should not be increased. Otherwise, the bearing capacity of the pole will be reduced. The change of the step of the large rail will directly affect the bearing capacity of the scaffold. When the step is increased from 1.2 meters to 1.8 meters. At the time, the critical load drops by 27%.

Scissor support is an important measure to prevent longitudinal deformation of aluminum scaffolding. Reasonable setting of scissors supports can also enhance the overall rigidity of scaffolding and increase the carrying capacity of scaffolding by more than 12%. Each set of scissors supports 5 to 7 roots (> 6 meters) across the pole, and the angle between the diagonal pole and the ground is between 45° and 60°. For single and double-row scaffolds with a height of less than 24 meters, a set of scissors supports shall be provided at both ends of the outer façade, and the bottom to the top shall be continuously arranged with the erection of the scaffold; the middle portion may be spaced no more than 15 meters.

Double-row aluminum scaffolding with a height of 25m or more, the outer façade must be continuously set along the length and height. The scissor slanting bar should be connected to the upright bar and the extended small crossbar, and the lower end of the bottom slanting bar should be placed on the paddle. The length of the scissors slanting rods is overlapped, the lap length is not less than 0.5m, and two screw fasteners are provided.

When the height of the aluminum scaffold is more than 24 meters, in order to enhance the rigidity of the horizontal plane of the scaffold, a diagonal bar can be added in the horizontal plane at the corner of the scaffold and in the middle every 6 spans, so that it becomes a zigzag or "ten" "Glyph." When the operation layer is encountered, it can be temporarily removed. When transferring to other layers, it should be replenished in time.
