Standard Specification and Installation Process of Scaffolding for Construction Steel Pipe Standards

Construction steel pipe is widely used in construction piling, structure, steel structure, load-bearing, drainage and other aspects. Materials are mainly carbon steel, stainless steel, alloy steel. One of the most common applications for carbon steel materials. The following small series introduces the specific specification and erection process of scaffolding for construction steel pipes.

Concrete pipe standard scaffolding specification:

1. In order to implement the state's technical and economic policies in the design and construction of fastener-type steel scaffolds, it is technically advanced, economically reasonable, safe to apply, and ensures quality. This specification is formulated.

2. This specification applies to the design and construction of floor-standing (bottom stayed) single- and double-row fastener-type steel tubular scaffolds for construction of industrial and civil buildings, as well as the design and construction of formwork supports in the construction of horizontal concrete structures.

Single-row scaffolding is not suitable for the following situations:

(1) The wall thickness is less than or equal to 180mm;

(2) The height of the building exceeds 24m;

(3) Lightweight walls such as empty bucket walls and aerated block walls;

(4) Masonry walls with mortar strength grades less than or equal to M1.0.

3. Before the construction of fastener-type steel scaffolding, the design and calculation of the bearing capacity of the scaffold structural members and the foundations of the uprights shall be carried out in accordance with the provisions of this specification.

4. Prior to the construction of fastener-type steel scaffolds, the construction organization design shall be prepared in accordance with the provisions of this Code.

5. In addition to the design and construction of fastener-type steel tubular scaffolding, it shall comply with the current national mandatory standards in addition to the provisions of this Code.

Scaffolding setup process:

1. The foundation or foundation must be added when erecting the scaffold, and the groundwork should be well handled. The poles of this project will be directly supported on the foundation slab or on the old soil at the bottom of the foundation pit, and the wooden support will be added. The padding on the old soil surface of the foundation pit must be stable and must not be suspended. When laying the base, pull the cable and pull the ruler. Place it according to the specified spacing and fix it.

2. The erection order of the steel pipe scaffold is: Place the sweeping bar (large bar close to the ground, height is 20cm) → erect the poles one by one, then fasten with the sweeping bar → install sweeping small bar and tie the pole or sweeping pole Clamping → Safety Step 1 (Cut fast with each pole) → Ahn's first step bar → A2 step big bar → Add a temporary diagonal bar (upper end and second step) Fastening, can be removed after the installation of two wall rods) → security third and fourth step large crossbars and small crossbars → Anlian wall poles → security poles → additional scissors → spread the scaffolding board.

3. The poles must be set up with equal distances and their longitudinal spacing should not exceed 1.8m. The lateral spacing of the poles is 1.0m, and the poles are 40cm from the wall. The vertical spacing of the small bars (ie, the scaffolding step distance) is 1.8m, the step spacing of the bottom floor shall not be greater than 2m, and the lengths of the inner and outer vertical bars selected by the small bars shall not be less than 30cm and 15cm, respectively. A scissor must be set on the outside of the scaffold every 9m. The angle to the ground should be controlled continuously from top to bottom between 45° and 60°.
