What is the distance between the outer frame and the building?

The distance between the outer frame and the building is not hard and fast. According to article 7.3.6 on page 42 of JGJGJ130-201,the distance from the wall end of the horizontal pole of the double-row scaffold to the decorative surface of the wall should not be greater than100 mm.

General construction practice: For example, when the main body of shear wall structure is constructed, the formwork should be installed and removed on the outside, which is convenient for operation. Therefore, the distance between the vertical pole and the external wall is generally about 350 mm During decoration, the horizontal pole will be moved inward 100mm away from the wall, and scaffolding will be laid on the inside, which is convenient for decoration engineering construction.

The vertical distance (along the length of the building) of the vertical pole is 1.5m and1.8m. ..

The selection of the horizontal distance of the vertical pole (the distance between the internal and external bent poles) is influenced by many factors, such as 1.0m for the bamboo basketry scaffold board and 1.2m for the wooden frame board.

The general interval is 1.5 or 1.8m, which is recommended to be the same as the longitudinal interval (safe, civilized and acceptable).

Of course, these dimensions can be adjusted, and you can look up the table in the specification, and calculate and determine the requirements beyond the selection conditions of the specification.

Therefore, the horizontal distance of the vertical pole of double-row scaffold refers to the distance between the inner vertical pole and the outer vertical pole, which is called the horizontal distance, and the horizontal pole connecting the inner and outer vertical poles is called the horizontal horizontal pole.

Double-row fastener-type steel pipe scaffold is a spatial structure system composed of big crossbar, small crossbar, column, wall connecting piece and bracing connected by fastener nodes. ?

Vertical pole is an integral part of engineering construction-scaffolding project, literally, it is an upright pole.

Extended data:

Vertical pole is an integral part of engineering construction-scaffolding project, literally, it is an upright pole. Poles have many requirements in terms of spacing and connection.

For example, columns must be butted with butt fasteners, and overlapping is not allowed. Also, the staggered arrangement of vertical rods and so on. The stress distribution between rods is uniform, and the overall stability is enhanced.

In the formwork structure, when only one vertical pole bears vertical load:

1. Due to the deformation and displacement of the central vertical rod itself, it has great influence on the deformation and displacement of its adjacent cross bars and adjacent vertical rods, but has little influence on other surrounding bars.

2. The vertical displacement of the central vertical pole and other components around it increases linearly with the increase of load.

3. During the vertical stress process of the central column, the vertical displacement of each point on each member of the formwork tends to spread and attenuate around the top of the central column, and the attenuation is faster.
