Problems solved by technology
The disadvantage is that the number of rods converging on the joints is large, and the fabrication and installation are more complicated than the plane structure, especially the spherical joints in the grid structure, which are difficult to weld and difficult to ensure welding accuracy

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] see first figure 1 As shown, the connection structure between the roof pipe truss and the steel pipe column of the present invention includes a roof pipe truss 13 and a steel pipe column 10. figure 2 As shown, the single roof pipe truss 13 includes an upper chord 131 , a lower chord 132 and a web 133 welded between the upper chord 131 and the lower chord 132 . recombine image 3 As shown, the steel pipe column 10 includes a column body 12 and a column head 11 welded on the top of the column body 12. The top of the column head 11 is a spherical surface, and is welded to the lower end of the lower chord 132 and the web bar 133 of the roof pipe truss 13; the column head 11 The bottom of the cylinder is a plane, which is welded to the top of the cylinder 12. The connection construction method of the roof pipe truss and the stee...

The invention discloses a connecting structure for a roof truss tube and a steel tube column and the construction method hereof. The construction method includes the following steps that a single frame roof truss tube is assembled; a steel tube column head is welded at the lower end of the assembled single frame roof truss tube; the above construction steps are repeated to finish welded connection of multi-frame roof truss tube and the steel tube column head; the adjacent frame roof truss tubes are welded and assembled to form a roof truss tube hoisting unit block through a secondary truss joint lever; the assembled roof truss tube hoisting unit block is hoisted so that the steel tube column head at the lower end of the roof truss tube hoisting unit block can be welded to a steel tube column body. Through the separation of the steel tube column head and the steel tube column body, the pre-assembly of the steel tube column head with an upper chord, a lower chord, a ventral rod, and the secondary truss, and the after-welding construction of the steel tube column body, quantity of high altitude welding work is reduced and difficulty in welding the roof truss tube and the steel tube column is reduced.
Description
technical field [0001] The invention relates to the field of engineering construction, in particular to a roof pipe truss and steel pipe column welding structure and a construction method for a steel structure system, which requires a large amount of high-altitude welding work, complicated welding connection nodes between a pipe truss and a steel pipe column, and requires high welding precision. Background technique [0002] The grid structure is a space steel structure product formed by connecting multiple rods through nodes according to a certain grid form. Because it has the advantages of space force, light weight, high rigidity, and good seismic performance; the grid structure is usually a space structure composed of two-way or three-way plane trusses, and there are also four-cornered inverted cones composed of rods. Spatial structure. The former is easy to construct and is suitable for the connection of various types of nodes, such as the Capital Gymnasium, the Interna...
