Steel structure construction prefabricated food workshop packing warehouse

Number of floors, height, and area of the building: the first floor above ground in this project; The total height of the above ground buildings is 10.650m,

The first floor has a height of 10.50m; The building area is 20790.31 square meters.

Architectural structure form: adopting light steel structure, partial frame structure, and the design service life of the main structure

Limited to 50 years; The structural safety level is level 2, the seismic fortification intensity is 7 degrees, and the design earthquake grouping is:

The third group is designed with a basic acceleration of 0.10g.

Fire resistance rating: The above ground part has a fire resistance rating of level two.

The non load bearing walls of the steel structure are made of polyurethane composite flat steel plates, and the foundation beams of the exterior walls of the factory are raised to the elevation

Below 1.2m, it is a 200 thick aerated concrete block wall with gray exterior wall tiles. Elevation above 1.2m

The wall is composed of 100mm glass wool felt composite board and single-layer profiled steel plate. Outer layer composite

The outer panel of the wall panel is made of 0.7mm thick aluminum zinc coated profiled steel sheet, and the inner panel is made of 0.5mm thick aluminum zinc coated profiled steel sheet

Board. The inner panel of the wall is made of 0.5mm milky white profiled steel plate, which is installed on the inner side of the purlin.

After the laying is completed, find the rules for the anchor bolts. Strictly position according to the axis and elevation provided.

Find the rules: It is required that all anchor bolts are aligned and the steel columns are placed in a straight line.

When hoisting steel columns, the foundation nuts should be leveled in advance. During hoisting, no one is allowed to stand within the lifting range of the crane. After the steel columns are basically in place, people should install them. The anchor nut should be tightened.

Lifting of steel beams after assembly: After the construction of steel column tie rods/column supports is completed, the steel beams will be lifted

Tie rod connection between steel beams: must achieve bolt tightening and consistent direction

The roof steel beams use high-strength bolts and do not require welding.

Platform beams are divided into main beams and secondary beams: the main beams are generally welded, and the wing plates are welded. Secondary beams are generally not welded.
