Power plant dry coal shed 100m span double -layer flat space frame high -altitude bulk construction

Power plant dry coal shed 100m span double -layer flat space frame high -altitude bulk construction

2024-06-28

The space frame structure of the emergency dry coal shed in the coal pile area of the power plant is irregular pentagon in plane shape, with a length of 121.958m and a maximum span of 99.949m. The roof of the coal pile area is a double-layer flat space frame, which is supported by reinforced concrete columns around the perimeter. The space frame structure is in the form of quadrilateral cone cylindrical space frame shell structure, and the joints are connected by bolt balls.

Space frame structure because of its novel structure, reasonable force, light weight, small amount of steel, a large number of steel structures have emerged from the late 1980s, increased by about 80 to 1 million m2 every year. Widely used in large sports venues, exhibition centers, theaters, shopping malls, terminal buildings, waiting halls, factory workshops, warehouses, TV towers, etc.

The main loads of space frame steel structure are divided into three kinds, which are action load, permanent load and variable load. Generally speaking, the loads include the self-weight of the space shell structure, the self-weight of the roof maintenance structure, the load of the suspended equipment pipe and the load of the cat walk.

The selection of space frame frame should be combined with the plan shape of the building, requirements, load and span size, support situation and economic factors such as comprehensive consideration. Usually, we divide it according to the span size as follows: above 60m span is large span; 30m to 60m is medium span; below 30m is small span.

Welding should follow a certain sequence, usually welding the middle node first and then expanding to the nodes at both ends of the truss. This helps to avoid dimensional deviations between the nodes of the joist caused by the accumulation of weld shrinkage towards one end.
