What should I do if I buy a channel steel layer?

I bought a channel steel layer, which needs waterproofing when decorating, because the biggest disadvantage of channel steel layer is water leakage, but don't worry too much. Now the channel steel layer is well treated and wrapped outside, which will also make the channel steel layer have strong corrosion resistance and water resistance.

What is channel steel layer?

Channel steel is a kind of section steel with grooves in shape. Channel steel layer is the surface paved with channel steel. When building a building, the channel steel layer is essential, and scaffolding is needed during construction. Generally, a layer of channel steel will be set on the scaffolding of seven or eight floors. Simply put, channel steel floor is the place where developers build scaffolding when building houses. The total height of channel steel cantilever frame shall not exceed 20m, and a layer of channel steel shall be set every 6 or 7 floors; In other words, the channel steel floor may be on the 7th floor,13rd floor,19th floor.

What are the advantages and disadvantages of channel steel layer?

Advantages:

1. Because the channel steel layer needs to bear the load transmitted by the external cantilever scaffold during the construction process, if the cantilever layer position of the building or the I-beam setting position can be determined in some construction drawing designs, the beam slab reinforcement at these positions will be strengthened. After determining the number of channel steel layers, some construction units will also reinforce the beam and slab reinforcement in these parts. Therefore, in theory, the ultimate load that the channel layer can bear is greater than that of the non-channel layer.

2. In recent years, more and more construction companies no longer use traditional channel steel scaffolding, but use more advanced rail climbing scaffolding. I-beam of channel steel layer is placed and the construction method is updated. Embedded steel plate installation, leaving no holes.

Disadvantages:

1. Water leakage may occur in the channel steel layer, mainly because the wall of this layer will be perforated during construction. The traditional I-beam cantilever beam is based on the principle that the load of external scaffolding is transferred to the floor through I-beam. Therefore, the floor is easy to crack and leak in the later period. When I-beams pass through the wall, a large number of holes will appear in the wall after I-beams are removed. If the sealing quality of these holes is unqualified, cracks and leakage will easily occur.

2. The shaking sound of channel steel layer is relatively loud. Generally, the smaller the channel steel size, the louder the shaking sound. On the contrary, the smaller the shaking sound. This will happen if the developer chooses a channel steel with smaller specifications and general quality when building a house.
