1. The wall structure should be symmetrical with the bolts of the building unit, the structure should be straight, the gap of the color plate should not be big or small, and the flashing and gap treatment must be appropriate.
2. The location of high-strength bolts should be reasonable, and the construction space of the torque wrench and the torque wrench should be considered. It is not necessary to install the high-strength bolts because the space is too small and the torque wrench and the torque wrench can not be in place, resulting in the failure of the high-strength bolts to break the plum blossom head or tighten the high-strength bolts. I have encountered some designs that don't even give the position of the sleeve.
3. When the beam column is used as the tie bar connecting plate, the hole is not extended properly. In some places, because the connecting plate on the tie bar is too long, the space is too small, and the tie bar is too long to put in. Some secondary beam structures often have this situation.
4. The connection between wind resistant column and steel beam shall be connected by spring plate as far as possible.
5. The connection plate of purlin should not be designed as square as far as possible, so it is easy to be assembled upside down in the workshop.
6. Check whether the roof panels have broken marks or whether there are adverse factors of thermal expansion and cold contraction under high temperature
7. After the completion of the project, the coating is also an important part of the project. We should pay attention to the quality, and strictly follow the quotation of the fire-resistant coating on the market.
