First of all, the purchase of scaffolding should carefully identify the quality of scaffolding good or bad, the current scaffolding market is also very disorganized, including the pursuit of profit maximization, some manufacturers in the scaffolding production process to cut corners and reduce costs, resulting in scaffolding quality is not up to scratch. If the construction unit is unable to distinguish between good and bad quality when purchasing, it may mistakenly buy the scaffold, which will lay a hidden safety hazard for the construction later.

In order to avoid such situations, how should we identify the quality of scaffolding when we purchase it?

1, look at the material:

When buying scaffolding, you can ask the seller to understand the material, to see whether the first-class steel pipe, many manufacturers in order to lower the cost, are a steel pipe and the second-class steel pipe mixed with the second-class steel pipe in the construction site is easy to crack, resulting in engineering safety accidents. So it is very important to buy scaffolding to see the material.

2, look at the appearance:

Appearance mainly look at the consistency of the glaze colour, flatness, surface gloss, smoothness, the degree of sintering on the back, etc.

3, look at the water absorption:

The less the scaffold absorbs water, the better. Scaffolds that absorb more water have poor frost resistance. The way to check is to compare the weight difference between a dry scaffold and a water-soaked scaffold, which is the water. The national standard stipulates that the scaffold water absorption rate is less than or equal to 12.0%, such as not up to standard, the quality must be a problem.

4, see cracked glaze:

Scaffolding cracked glaze is a common phenomenon. Cracked glaze scaffolding winter freezing will appear after the glaze layer peel off, thus losing lustre and waterproof performance. The inspection method is to see if the surface of the scaffold has fine cracks like spider silk. It is more obvious after getting wet or immersed in water and sticky dust.

5、Look at the degree of sintering:

The higher the degree of sintering, the stronger the scaffold. The method is to listen to the sound of knocking, the crisper the sound of metal when knocking the better the scaffold. The national standard of flexural strength of ≥ 1020N, such as failure to meet this standard, the quality to be considered. In addition, the scale of the manufacturer is also critical, try to work with a large and well-known scaffolding manufacturer.

Comply with the scaffolding erection specifications, correct operation, strictly prohibit illegal command and illegal construction, can effectively avoid the occurrence of safety accidents.

Finally, the relevant construction protection facilities:

Such as special types of work with a permit, construction site personnel with a good helmet and the corresponding labour protection supplies, work at height, to tie a good seat belt, construction personnel must comply with safety construction rules and regulations, construction site need to hang posted safety construction signs, etc., these safety measures can greatly reduce the occurrence of safety accidents.
