What are the construction difficulties of steel structure interlayer?
The construction of steel structure interlayer is generally used as workshop or some buildings with large space as interlayer, which can be used as platform or temporary office area, and the construction of steel structure interlayer will not affect the internal production. As long as the construction is properly arranged and the two are staggered and operated at the same time, they will not affect each other, which can not only accelerate the construction of steel structure interlayer, but also not hinder the room Internal production.
The owner attaches great importance to the construction quality of the steel structure interlayer. The engineering company should also know the difficulties of the steel structure interlayer, focus on overcoming the difficulties, and improve the construction quality of the steel structure interlayer. The rooting of steel structure interlayer is the key to safety. The so-called rooting is to radiate the load of steel structure interlayer to the root through the main beam, and transfer it to the original structure from the root, so as to reduce the pressure of load on the steel structure interlayer.
The rooting of steel structure interlayer is not a simple thing. In order to be reasonable and effective, it needs professional construction personnel. When anchoring, the holes should be cleaned, otherwise the anchoring strength will be affected, and the bearing quality of anchoring will be reduced. For the production of anchor plate, the anchor plate is the coupling part of anchor bolt. When calculating the thickness and area of the anchor plate according to the total radiation load of the main beam, the supporting plate or connecting plate shall be welded by sectioning. During installation, pull-out test shall be carried out for anchor bolts, and soil method test shall be carried out for small shear force. When drilling holes for all anchor plates, consideration shall be given to the situation of test bars, which can be drilled more and installed less, but not less than the design load. If there is a gap between the anchor plate and the concrete beam or concrete column, it can be grouted with glue or grouting material, and the main beam can be loaded only after all the anchor bolts are solidified.
The main beam of the steel structure sandwich is the second key to safety. The main beam is directly related to the bearing and span of the roof. If the span of the steel structure sandwich is small, I-beam or H-beam can be selected. After the steel beam is selected, it shall be polished, derusted, cut and primed. After arriving at the site, both ends shall be measured and anchored for fine cutting. Different from other steel structure projects, the length of most beam purlins is variable, so they are cut after measured. The main beam of steel sandwich plays a key role in the load-bearing of the whole structure, and has high requirements for materials or cutting, so we should pay attention to the installation of the main beam of steel sandwich.
The connection of steel structure interlayer is usually made by welding or high strength bolt. Welding shall be carried out in accordance with the construction requirements, without missing welding. Full welding shall be carried out to ensure that the welding quality of steel structure interlayer is up to the standard and improve the installation quality of steel structure interlayer.
