Prefabricated Steel Structure Factory Plant Workshop
Project Name: New Factory Two piece Can Workshop
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 in position, and after placing the steel column, it should be in a straight line
The welding of anchor bolts should be firmly connected while ensuring the axis and elevation. The bottom of the screw and the bottom of the bolt should be cross welded firmly with the main reinforcement. Shake the bolts for inspection after welding is completed.
Installation of platform beams and steel columns
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.
Roof purlins are divided and bolts are installed. Use Z-type for large spacing and C-type for small spacing.
Install roof panels
Installation of inner wall panels: The panels are parallel to the steel columns, and attention should be paid to the joints between the two panels not being too large. Self tapping nails should be straight, the board should be flat and straight, and the spacing between self tapping nails should be consistent
