Project description:
Length: The total length of the plant needs to be determined. Whether there is a requirement for the column spacing, the column spacing is generally 6m, but it can also be 7.5m, 9m, or 12m;
Span: generally 9-36m, with 3m as a multiple, when the span is large, it is necessary to determine the design of several spans;
Height: indoor floor to the intersection of steel column axis and steel beam axis (clear height of plant), without lifting the crane should be 4.5-9m; when there is a crane, the specific model and lifting height of the crane should be determined;
Whether the roof and walls need to be insulated.
Main Components
The main components of steel workshop include steel column, steel beam, wind-proof column and crane beam.
☆ Steel column: It can be a H-shaped steel column with a constant cross-section or a H-shaped steel column with a variable cross-section.
It is easy to manufacture, safe and reliable, and the main material is Q235B or Q345B.
When the horizontal span of the steel workshop building does not exceed 15m and the column height does not exceed 6m, the steel column should be made of H-shaped steel with equal cross section.
When the span of the factory building is greater than 15m and the column height exceeds 6m, the variable-section steel column should be adopted.
☆ Steel beam: Commonly used welded composite steel beams consist of an I-shaped section consisting of upper and lower flange plates and webs. The main material is Q235B or Q345B.
☆ Wind- resistant column: The wind-resistant column is the structural component of the gable wall. The function of the wind-resistant column is mainly to transmit the wind load of the gable wall. The upper part is transmitted to the entire steel frame structure through the connection with the steel beam, and the lower part is transmitted to the foundation through the connection with the foundation. The main material It is Q235B or Q345B.
☆ Crane beam: The beam used to install the crane track is called the crane beam, which is generally installed on the upper part of the factory building.
Advantages of steel structure buildings.
Steel Structure warehouse is a kind of metal building , which is made of high-strength steel and offers excellent insulation and durability. It is designed with a portal structure and provides optional insulation so that it can meet the needs of the customers. The walls and roofs of the steel structure worehouse are made of sandwich panel or color steel sheet, and the purlin is made of C-section or Z-section steel. As for the door, it can be a rolled up door or a sliding door.
Compared with traditional concrete, steel structure has obvious advantages in the construction period, energy-saving, and earthquake resistance. As a green and low-carbon building, it is in line with the current environmental protection concept.
