Outside the frame, even the wall pieces should be set in two steps and three spans.

The distance between the vertical poles in the horizontal direction along the long direction of the scaffold is called span, and the number of layers up and down the scaffold is called interval. Step distance and span refer to the arrangement of the wall parts (rods) of the fastener-type steel pipe scaffold respectively. The height of the three horizontal bars is 1.8M, and the distance between the four vertical bars is1.5m. The outer frame is regarded as a plane, and the two steps refer to the two spaces composed of three horizontal bars. A spacing is called a step, so there is a longitudinal spacing, a three-span refers to three spacings composed of four vertical poles, and a spacing is called a span, so there is a horizontal spacing. Two steps and three spans means that the distance between wall connecting rods is the distance between two vertical layers and three horizontal uprights.

What are the specification requirements for the outer frame wall?

First of all, the design specification of wall connection parts must be based on its quantity and installation area, so as to customize the construction scheme. In general, we can divide it into three steps and three spans, two steps and three spans, etc. The area of the wall should be at least 20 to 40 square meters. If there is a problem somewhere, it should mainly be a diamond arrangement.

What is the depth of the wall?

1, in fact, even the wall column has to be calculated to get the corresponding number. Several points should also be considered in the calculation. Wind load and axial force of out-of-plane deformation of pipe rack must be considered, and they are also indispensable parts in construction scheme. Even the steel pipe of the wall should be buried first, and the length of the steel pipe has certain requirements, usually 2/3 of the total length. If the specification is not accurate, it can only be determined according to the site construction situation.
