First, material requirements 1. Steel pipes should be ordinary steel pipes specified in the current national standard “Straight Seam Electric Welded Steel Pipe” GB/T13793 or “Welded Steel Pipe for Low-Pressure Fluid Transportation” GB/T3091, and their materials should comply with the following p

1. The steel pipe shall be straight and smooth, without defects such as cracks, rust, delamination, scarring, or burrs, and the vertical pole shall not use steel pipes with cross-section extension; 2. The surface of the casting shall be flat, without defects such as sand holes, shrinkage holes, cra

1. Steel pipe (vertical pole, sweeping pole, horizontal pole, scissor brace, and tossing pole): Steel pipes shall adopt Q235 ordinary steel pipes specified in the national standard GB/T13793 or GB/T3091, and the model shall be 48.3×3.6mm, with a wall thickness difference of 0.36mm. The maximum we

Disc-type scaffolding is a new type of scaffolding, which is an upgraded product after the bowl-type scaffolding. It is also called chrysanthemum disc scaffolding, plug-in disc scaffolding, wheel disc scaffolding, and disc-type scaffolding. The socket is a disc with 8 holes in it. It uses φ48*3.2

1. Bowl-hook node: a cap-fixed connection node composed of upper and lower bowl-hook, limit pin, and horizontal rod joint. 2. Vertical pole: a vertical steel pipe member with a movable upper bowl welded with a fixed lower bowl hook and a vertical connecting sleeve. 3. Upper bowl hook:

1. The bottom of the cantilever scaffolding should be equipped with vertical and horizontal sweeping rods according to the specifications. Steel bars should be welded on the upper surface of the cantilever steel beam as the vertical rod positioning point. The positioning point should not be less tha

1. The inspection of steel pipes shall comply with the following provisions: ① There should be a product quality certificate; ② There should be a quality inspection report; ③ The surface of the steel pipe should be straight and smooth, and there should be no cracks, scars, delamination, misali

1. The installers and dismantlers of the fastener-type steel pipe scaffolding must be professional scaffolders who have passed the assessment, and the scaffolders must be certified before they can take up their posts. 2. The scaffolding erectors must wear safety helmets, safety belts, and non-slip

When it comes to support systems in construction, wheel-lock and disc-lock scaffolding are two common construction methods. First, let’s take a deeper look at their differences: 1. Technical background: As an international mainstream, disc-lock scaffolding originated from the European and A

1. Materials should be 100% inspected by current national standards. All scaffolding materials must be properly stored after being inspected and qualified and must have product quality certificates, production licenses, and test reports from professional testing units. 2. Safety protection equipmen

As a new type of scaffolding, the application characteristics of industrial scaffolding are concentrated in the following aspects: 1. High safety: The length of a single pole of an industrial scaffolding is generally no more than 2 meters. Compared with the traditional 6-meter-long ordinary

Speaking of disc-type scaffolding, its advantages of strong bearing capacity and high safety factors are well known. However, if you have not used it, you may not understand the advantages of high efficiency and short construction period of disc-type scaffolding. Reason 1: The engineering u
