Manufacturing method for welding round, square and flat pipes into *-shaped reinforced through beam columns

Abstract

The invention provides a manufacturing method for welding round, square and flat pipes into *-shaped reinforced through beam columns. Steel plates are welded into *-shaped and triangular through long-strip steel plate center frames and then are punched and welded into pipe inner holes of square, multi-square, flat square, flat round pipe, quadrate and round pipes, so that the vertical force strength and the straight strength of the pipes are enhanced. The pipes can serve as bridge upright columns, electric upright columns and bridges. The diameter of the pipes is shortened, and the vertical force and the strength of the pipes are enhanced. One pipe can be used as three pipes. When the pipes serve as house upright columns, bridge upright columns and electric upright columns, the space between the columns is enlarged and the width of traffic roads and vehicle roads in the bridge is increased. The high-voltage electric upright columns can serve as ultrahigh columns. The reinforced square pipes can be applied to house beams. The road surface height of the bridge can be reduced when the pipes are applied to bridges, so that the purposes of the pipes are increased and the application range of the pipes is enlarged. The pipes are manufactured according to national standard building structure welding regulations JGJ81-2002, JZ18-2002 and GB.GB / I welding technology and are implemented according to the design technology of the invention.

Description

1. Technical field: [0001] The invention relates to a method for reinforcing the inside of a pipe hole, in particular to welding a hexagonally reinforced round pipe, a square round pipe, a flat square pipe, and a round pipe into a reinforced through-heart pipe in the shape of a rice and a triangle. 2. Background technology: [0002] At present, the known hexagonal tubes, multi-square tubes, oblate tubes, flat square tubes, and high-voltage utility pole column tubes are all hollow tubes, and the tube holes are not welded and processed with steel plates, and reinforced into tube holes, triangular and rice-shaped through-heart tubes. of. 3. Contents of the invention: [0003] Can not make bridge column, tower column, house column, bridge crossbeam, bridge girder in order to overcome existing pipe hole without reinforcement molding, the deficiency that bridge pull stand can not expand use. [0004] The invention provides tubular pipe hole shape welding, forming a triangular a...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages that there is no reinforced shape in the existing pipe holes, it cannot be used as bridge columns, tower columns, house columns, bridge beams, bridge girders, and the bridge support frame cannot be expanded and used.
