Description of the symbols: the steel plate comprises a building steel column 1, a round steel pipe 2, a steel pipe sealing plate 2-1, a supporting plate 2-2, building section steel 3 and a steel batten plate 4.
Detailed Description
The present invention will be described in detail with reference to the following preferred embodiments.
Example one
As shown in fig. 1-3, the cylindrical head structure of the multi-node intersection part of the structural steel frame comprises a structural steel column 1 and structural steel 3; the method is characterized in that: the circular steel tube sealing device is characterized by further comprising a circular steel tube 2 with a cylindrical head, a steel tube sealing plate 2-1 is welded at the end opening of the circular steel tube 2, supporting plates 2-2 are arranged in the circular steel tube 2, the two supporting plates 2-2 are welded in a crossed mode, the two crossed supporting plates 2-2 are arranged in the circular steel tube 2, and the edges of the supporting plates 2-2 are welded with the inner wall of the circular steel tube 2; the end part of the building section steel 3 is welded with the circular steel tube 2, so that a multi-node intersection structure can be formed; or, holes are drilled on the surface of the circular steel tube 2, the building section steel 3 is inserted into the circular steel tube 2, and the circular steel tube 2 is welded. In the aspect of the stress form, the steel pipe is sleeved outside the steel column profile steel, so that the stress form of the steel column member is unchanged. As for the stress form of the member connection, the beam-column connection form is not changed, and the stress form is also not changed. The welding of the outer sleeve steel pipe and the section steel is only required to meet the welding checking calculation of the integrity of the member according to the load of the node, and after the checking calculation of a design unit, the load requirement and the design requirement are met.
