How to reduce the cost of steel structure factory shed?
How to reduce the cost of the steel structure factory shed and meet the needs of customers? First of all, we need to know that when formulating a plan, we must not only consider reasonable energy saving, but also effectively save time during the steel structure installation process. The amount of steel used is reduced to a very low level to meet the budgets of different customers while ensuring quality. So, how to reduce the cost of steel structure factory shed?
1. Selection of column spacing
The comparison of the economical column spacing shows that the column spacing with the best cost performance under the standard load is 8~9m. When the column spacing exceeds 9m, the steel consumption of the roof purlin and wall frame system will increase too much, and the overall cost will not be economical. Therefore, when the load is greater, the column distance should be reduced accordingly. Generally, for a factory building of more than 10 tons, the economic column spacing should be 6~7m. When arranging column spacing, if unequal column spacing is required, the end span should be arranged to be smaller than the middle span as much as possible. In addition, when using continuous purlin design, the use of smaller end span can make the roof purlin design more convenient and economical.
2. Determination of reasonable span
Under normal circumstances, when the column height and load are constant, appropriately increasing the span will not only save space, but also lower the cost of the foundation, and the overall benefits will be considerable. Therefore, when designing the portal steel frame, a reasonable span should be determined according to the height of the house, and the correct choice is not to blindly pursue a large span.
3. Selection of roof slope
Studies have shown that different roof slopes also have a greater impact on the steel consumption of the steel frame, generally 1/10~1/30. According to tests, for a single-span steel frame, reducing the weight of the steel frame is a better way to increase the slope of the roof. The greater the slope, the more steel will be saved. However, the situation is different for multi-span steel frames. A large slope will increase the steel consumption of the frame, because a large slope will lead to an increase in the length of the inner column.
4. Cornice height selection
The height of the cornice also has a great influence on the cost. The increase of the cornice height will lead to the increase of purlins on the wall, and the steel consumption of the columns will also increase.
The Canglong steel structure manufacturer briefly introduced several feasible schemes on how to reduce the cost of steel structure factory shed, hoping to help everyone.
