Problems solved by technology

The socket welding method of pipe fittings has disadvantages such as difficult construction, high cost of fusion-welded pipe fittings, and poor reliability of fusion-welded connections.
Butt welding connections can save costs, reduce construction difficulty, and ensure the reliability of pipeline connections; however, due to the lack of supporting equipment for butt welding connections, operators need to carry heavy HDPE pipes and butt welding machines. Unfavorable conditions such as high difficulty, high requirements for operator cooperation, and difficult alignment of HDPE pipes

Abstract

The invention discloses a welding support and method for a horizontal HDPE pipeline of a siphonic type rainwater drainage system and relates to the technical field of construction of the siphonic type rainwater drainage systems. The welding support facilitating welding of the horizontal HDPE pipeline of the siphonic type rainwater drainage system is provided. The welding support comprises an installation piece, two portal frames, a welding platform and two pipe supporting frames, wherein the installation piece is provided with an installation groove and two portal frame grooves, the upper portions of the two portal frames are hung on the installation piece, the two portal frames are located in the two portal frame grooves, the lower portion of each portal frame is provided with two connection screw rods, the four connection screw rods penetrate through the four corners of the welding platform correspondingly, supporting nuts are connected to the connection screw rods, the supporting nuts support the welding platform, the two pipe supporting frames are arranged on the welding platform in a spaced manner, the top of each pipe supporting frame is a V-shaped pipe supporting plate, and the height of the pipe supporting frames can be adjusted. By the adoption of the welding support, the HDPE pipes and a butt welding machine can be supported, and the two HDPE pipes can be conveniently made opposite to each other.

Description

technical field [0001] The invention relates to the technical field of construction of a siphon rainwater system, in particular to a welding bracket and a welding method for HDPE horizontal pipes of a siphon rainwater system. Background technique [0002] The rainwater drainage system is a relatively advanced roof rainwater drainage system in the world today. It originated in Europe and was introduced in my country in the early 1990s. After a lot of tests and in-depth research, my country has successfully developed a siphon roof rainwater drainage system and widely used it It is applied to roofs with large spans and complex structures such as large factories, exhibition halls, airports, sports fields, and high-rise podiums. [0003] The pipes of the siphon rainwater drainage system generally adopt high-density polyethylene (HDPE) pipes, and the horizontal pipes are usually suspended at a higher position in the building. The pipe connection methods are mainly divided into two ...
