The point of steel structure workshop building process
Release time:2020-07-18
As a powerful steel producer in China, stainless steel plate has been used as industrial plant for a long time. In fact, it is also divided into light steel structure and heavy steel structure processing plant.
The construction of steel structure workshop is divided into the following parts:
1. Embedded parts, (can stabilize the structure of industrial plant)
2. The column head is usually made of H-shaped steel or C-shaped steel (usually connected by angle iron)
3. Generally, C-beam and H-beam are used. (the height width ratio of the product in the center depends on the span of the beam)
4. Steel purlin: C-shaped steel and Z-shaped steel are generally used.
5. The supporting point and pushing bar are generally round steel.
6. There are two kinds of tiles. The first one is sheet tile (color steel roof). The second is sandwich panel. (polyurethane material or rock wool board sandwiched in the middle of the double-layer color coated steel plate has the effect of warming for many days and cooling in summer, and also has the actual effect of sound insulation, noise reduction and fire safety.
The key advantages of steel structure workshop are as follows:
1. Light quality, high compressive strength and large span: Although the relative density of stainless steel plate is larger than that of other building decoration materials, its compressive strength is very high. Under the same bearing condition, the steel frame structure has small weight and can be made into structure with large span.
2. Short construction period: the key manufacturing of prefabricated components of industrial plant is carried out in the processing plant, and the prefabricated components are transported to the site for installation. In the prefabricated construction work, the construction is convenient and fast.
3. Strong fire safety: when the surface temperature of stainless steel plate is within 150 ℃, its compressive strength changes little, when the temperature exceeds 150 ℃, its compressive strength decreases significantly. Generally, fireproof materials will be applied on the surface of steel frame structure, which will produce a layer of protective film to improve the fire resistance rating of prefabricated components. Naturally, the effective zoning of evacuation exit and the application of fire shutter door are also very important.
4. Waterproof layer moistureproof: the infiltration of precipitation is mainly based on the connection point or gap. To ensure the waterproof layer moisture-proof, it is necessary to use the sealing gasket at the screw opening to fix it. Sealant or electric welding should be used at the joint of steel bars of the board. It is better to use a full-length board to remove the overlapping of steel bars, and to solve the moisture-proof problem of tight expansion at various connection points.
5. Sound insulation, noise reduction and heat insulation: add sound-absorbing materials (generally glass fiber cotton) in the steel structure building layer, or add broken pole heat insulation and heat insulation reflective surface architectural coating on the surface of colored stone metal tile.
6. Natural ventilation and temperature reduction: generally high frame industrial buildings, without special power and large scalding machinery and equipment, the staff are not very concentrated, there is no odor or smoke caused, the application of axial flow exhaust fan + ventilation building method is OK. For the steel structure workshop with high frame and large span, it is better to install exhaust fan with large air volume on the roof to exhaust the air system outdoors; air pressure in the room will be generated; a lot of fresh air will be forced into the workshop from around the production workshop, resulting in air convection; the actual effect is correct.
7. Good lighting: install lighting tile or light laminated glass in special parts of flat roof, fully consider the service life of panoramic skylight, and the problem of harmony with the roof, and the junction must be well moisture-proof.
