Joint design and construction of steel structure shop

Fast Steel Factories for you to introduce the steel structure workshop node design and structure, let's understand it. Steel structure workshop node design and construction: steel tube roof truss is only one of various types of steel tube structure, in the single-layer steel structure workshop, steel tube roof truss is mainly plane truss, in civil buildings, steel tube roof truss using space truss is more common. Pipe roof truss and steel roof truss in design due to the different connection form has brought many changes, which obviously is pipe roof bar node more widely used in steel tube structure is adopted to a node plate connection, the connection way make the pipe roof truss node design and construction is completely different from traditional node connection plate design and construction.

1. Although no knot plate connection can save the knot plate material and properly simplify the node structure, the connection structure of pipe fittings is more complex, the manufacturing process is higher, and the plane connection is relatively simple. In addition, the welding of direct intersecting connection is more difficult, and the welding process is more demanding.

2. Design specifications and structural requirements of directly connected joints of steel tube roof truss, applicable scope of geometric parameters of joints in various steel structure workshops, calculation method of bearing capacity and calculation method of joints.

3, steel structure workshop roof frame design should be simplified and unified roof frame node structure as far as possible, reduce the number of nodes, staggered in the same chord node (plane truss) on the belly rod shall not exceed 3.

4. The thickness of the steel tube wall welded between the steel tube roof truss and the tension rod should not be greater than 25mm. Otherwise, measures should be taken to prevent the layered deformation of the larger tensile stress along the direction of the welding thickness of the tension rod.

Although steel tube roof frame than steel roof frame has certain advantages of saving steel, but its unit price is generally slightly higher than the ordinary profile, and the complexity of processing and manufacturing will weaken or offset this advantage, in the design should be comprehensive balance of the influence of various factors, the steel structure workshop engineering cost control within a reasonable range.
