Steel structure loft is mainly composed of steel structure as skeleton support and different floor bearing plates. Generally, this kind of steel structure loft is made to meet the needs of increasing the family use area and providing enough space for people or objects. Therefore, in order to manufacture the steel structure loft in the family, the following points should be paid attention to.
Before construction, it is necessary to understand the preconditions for the construction of steel structure interlayer. In short, it's just to see if your house is suitable for this, and make sure there are enough stories. Generally speaking, to ensure that the single-layer partition floor is not less than 2.6 meters, of course, this is to live in the loft as the standard. If the builder only needs to place objects, then of course the height is determined by the builder himself.
In terms of material selection, it is not recommended to use hollow steel such as square steel and pipe steel for steel structure interlayer. This kind of steel is very difficult to brush antirust paint inside, once the heat expansion and cold contraction, water vapor condensation is very easy to rust, resulting in fragile and unstable structure, collapse tragedy.
It is also very important to select the bolts for the connecting part. There are two choices in the connection of steel structure interlayer. Expansion bolt is the way of physical connection, while chemical bolt uses the chemical reaction between chemical agent and concrete to fix the structure. Each has its own advantages and disadvantages, which requires the builder to choose the corresponding bolt according to the local situation and construction requirements.
