Connection method for north and south poles of heavy sphere structure

Abstract

The invention relates to the technical field of building material connection, in particular to a connection method of north-south pole connection of a heavy sphere structure. The connection method comprises the steps that (a), a plurality of evenly distributed inner arc-shaped frames are welded by a meridian ring belt to form a first sphere structure, and all top ends of the arc-shaped frames areattached to the cambered face of a pressing ring; (b), a plurality of evenly distributed outer arc-shaped frames are welded by a ring belt to form a second sphere structure, and all top ends of the arc-shaped frames are attached to the cambered face of a pressing ring; (c), the pre-fixing between the first sphere structure, the second sphere structure, an upper pressing ring and a lower pressing ring is completed; (d), the inner arc-shaped frames are welded to the cambered face of the pressing ring; and (e), the outer arc-shaped frames are welded to the cambered face of the pressing ring. Theconnection method of north-south pole connection of the heavy sphere structure performs connection by welding the pressing rings at the north and south ends of the spherical structure, the problems ofwelding seam overlapping and welding heat dispersing are avoided, and installation speed is accelerated and installation precision is improved.

Description

technical field [0001] The invention relates to the technical field of building material connection, in particular to a connection method for connecting the north and south poles of a heavy spherical structure. Background technique [0002] For the heavy-duty structural modeling at the north and south poles, and both ends of the meridian are directly welded to the main rod, the disadvantages are that the welding volume on site is large, the welding seam overlaps, and the welding heat affects the material mechanics after cooling. The performance adopts the annealing effect, which reduces a series of problems such as material properties, narrow construction space, and large deviation of rods. Contents of the invention [0003] The technical problem to be solved by the present invention is: In order to solve the technical problems described in the background technology, the present invention provides a connection method for connecting the north and south poles of a heavy-duty...

Problems solved by technology

[0002] For the heavy-duty structural modeling at the north and south poles, and the two ends of the warp are directly welded to the main rod, the disadvantages are that the welding volume is large on site, the welding seam overlaps, and the welding heat affects the material mechanics after cooling. The performance adopts the annealing effect, which reduces a series of problems such as material properties, narrow construction space, and large deviation of rods.
