Problems to be paid attention to in the construction of bearing plates of multi-story steel structure factory building

The floor slab is widely used in the field of steel structure construction. It is used as the tensile reinforcement of the concrete floor slab, which not only increases the height of the floor slab, but also saves the amount of steel and concrete, and saves a certain amount of construction time and cost. Today we come Learn about the precautions during the construction of the multi-layer steel structure factory floor board!

1. The construction must be carried out in strict accordance with the drawings

For multi-story steel structure workshops, before the construction and installation of floor support plates, the corresponding row of plates shall be drawn, and construction shall be carried out according to the drawings. Laying of floor slabs should start from one end of the floor, adjust the position and fix while laying. When there is a hole, install the floor board first, and then cut the size of the hole according to the actual position of the hole.

2. Pay attention to the construction of pegs

Studs are connecting pieces between the floor beams and reinforced concrete floor slabs that play a combined role. For the construction of the studs of the multi-layer steel structure workshop, the arc-type stud welding machine and welding gun are used, and the deoxidizing arc heat-resistant ceramic seat ring is used.

3. The method of stud welding

In the multi-layer steel structure workshop, the stud welding method first connects the power of the welding gun of the welding machine, and the cylindrical stud is sleeved on the welding gun. The arc-proof seat ring starts the welding torch, the current melts, and the seat ring generates arc light. After a short period of time, pay attention to the pegs, press the base material to melt at a certain speed, cut off the power, and fix the columnar pegs to the base material.

After the welding is completed, the quality of the completion should be inspected, mainly hammering, and the surface inspection of the appearance is used as a guide. If the welding seam cracks, then the stud is discarded and a new one must be welded nearby.
