The steel structure interlayer is used in the building of the residence, office building, factory building, gymnasium so on which the net height is too high, that is, the rational use of space to increase the use of the area, but will damage the appearance of the original. So, what kind of method does the steel structure sandwich construction have? Guangdong Tianchen Steel Structure Engineering Co. , ltd.-steel structure engineering, Guangdong steel structure engineering, steel structure engineering manufacturers to say to You:

1. Rooting is one of the keys to the safety of the steel structure sandwich, the so-called root is to transfer the load of the new steel structure sandwich floor through the main beam to the root, the root to the original structure, just like a tree can stand without a strong root tree, in the actual construction of the first to determine whether the fixed point is a load-bearing structure. The second is to detect the hardness, thickness, reinforcement of the original structure, (non-load-bearing structure can meet the construction of the original structure, need to do independent support, but independent support components also need to do on the load-bearing beam other components) , do break the main bar when turning hole, according to the depth of technical requirements, diameter turning hole, according to the roof load configuration anchor bolt. The hole must be cleaned before the anchor bolt is implanted, otherwise, the anchoring strength will be seriously affected. When the anchor bolt is implanted, the rotation speed can be too fast, which will cause incomplete mixing of the medicine, too slow will cause drug running, which will reduce the pulling force, after implantation according to the temperature waiting time before construction. The manufacture of the embedded plate, which is the coupling part of the anchor bolt, to calculate the thickness area of embedded plate (value bar anchor plate is larger than high strength bolt anchor plate, which makes up for the low success rate of value bar) according to the total load of main beam, it is necessary to weld the section of supporting plate connecting plate. When installing, the anchor bolt should be tested by pull-out test, the soil test should be carried out for the small shear force. If there is a gap between the embedded plate the concrete beam column, the main beam can be loaded after all the anchors are solidified.

2. The main beam is the second key of safety in the steel structure sandwich engineering, if a tree foundation is good the trunk can bear the external force is also in vain, the choice of the main beam the roof load, span is a direct relationship, if the span is small, you can choose I-steel, H-steel, steel beam selected to be polished rust removal, cutting, primer treatment, to the scene after the measurement of both ends anchoring in the fine cutting, mezzanine engineering other steel engineering is different, most beam purlins are variable length, so after the actual cutting, if the span is small to choose section steel as far as possible

3. The construction of connecting steel structure interlayer is mainly steel beam connection, 1 welding, 2 high-strength bolt connection. In large projects, high-strength bolt connections welding are generally used, because the site welding power supply allow this to go without saying, in the steel structure mezzanine site often is the space is narrow, the main beam is difficult to enter, even in the outside after the break in the access connection, mechanical easy to use, hand-lift splicing after the lifting of steel beam connection.
