Key points of structural design of steel structure workshop

Because there are many deficiencies in the structural design of steel structure workshop, it has greatly slowed down the industrial development of steel structure and become a serious problem. The following is to explain the structural system, construction position and elevator setting of the steel structure plant from the speed steel structure.

First, the structural system of steel structure workshop

Steel structure workshop because of the use of building requirements, generally adopt large span space, structure part of the general use of frame structure. Frame shear wall structure can be used when the steel structure workshop has more floors and more complex technology.

The arrangement principle of steel structure workshop is to make steel structure column grid even symmetrical arrangement as far as possible, make steel structure factory building center and stiffness center in the same position, so that we can reduce the space change effect of steel structure workshop, steel structure factory building structure design for simplicity, symmetry, force is fluent and clear, to prevent the occurrence of stress concentration phenomenon of structure or component structure mutation, Caused by concave Angle and contraction phenomenon and vertical changes caused by too much external pick and adduction, and strive to vertical stiffness without mutation or less mutation. If it is a multi-layer steel structure workshop, this structure has a larger span and fewer columns, smaller column distance direction size, and more columns. Most of the steel structure workshop structure is horizontal control, which can balance the horizontal and vertical seismic capacity, so that the design is more economic and reasonable, such a design can make the structure of the steel structure workshop more stable.

Two, the construction position of steel structure workshop

The construction position of steel structure workshop is very important, to avoid building in the crust cracks above, because such a location is usually earthquake prone zone, easy to cause uneven settlement of steel structure workshop. The expansion joint of the steel structure workshop in the earthquake area is one. When the steel structure workshop is longer, the following structural measures and construction measures can be taken to set fewer expansion joints and shockproof joints.

1, in the construction, every 40 meters set an 800 mm and a 1400 mm wide post-pouring belt, post-pouring belt location in the structure of the least influence on the force of the section.

2, in the top layer, bottom layer, gable and inner longitudinal wall end of the wall and other parts of the greater impact of temperature, appropriately improve the reinforcement rate.

3. Thickening the roof insulation layer or setting up the overhead layer to form the ventilation roof.

Three, the elevator setting of steel structure workshop

Due to the weight of the equipment and the goods are heavier, and the item has a vertical transportation needs, so in the steel structure workshop internal need to set up the elevator, the elevator shaft stiffness of reinforced concrete is very big, can produce eccentric loading for steel structure workshop, so for the position of the elevator shaft design to set in the center of gravity position, do not set up in the Angle of steel structure workshop and end.
