Description

Technical Field

[0001] The utility model relates to the technical field of rectangular tubes, in particular to a connecting component. Background Art

[0002] In the household photovoltaic full-enclosed color steel solution, in addition to adding diagonal braces on the south side for columns exceeding a certain height, in order to facilitate the installation of sealed color steel on the north side of the column, diagonal braces, crossbeams and diagonal beams are also required on the north side of the column. Unlike the windward side on the south side, the north windward side is mainly supported by the diagonal beams and crossbeams on the north windward side, so the diagonal braces are in the form of rectangular tubes. Since the columns of this solution mainly use U-steel, it involves the connection between U-steel columns and rectangular tube diagonal braces. Compared with U-section components, it is more difficult to connect columns with rectangular tubes. At present, U-steel columns and rectangular tubes are usually connected with triangular connectors. When the triangular connector is connected to the rectangular tube diagonal brace, one end of the rectangular tube diagonal brace is usually inserted into the triangular connector and then welded. The disadvantage of this method is that since one end of the rectangular tube diagonal brace is inside the triangular connector, it is limited by the operating space and angle, and the rectangular tube diagonal brace and the triangular connector cannot be fully welded, so the strength cannot be guaranteed, and the connection between the triangular connector and the column is difficult. At the same time, this method requires that the transverse dimension of the rectangular tube diagonal brace must be smaller than the net transverse dimension inside the triangular connector, and the use conditions of the rectangular tube are limited.

[0003] In addition, due to the decentralized nature of household photovoltaics and the different house types in different places, for some U-shaped inclined beams that need to be fixed to the gables by diagonal braces, when the local stress is large, rectangular tubes need to be used to replace the U-shaped diagonal braces. This also involves the situation where the U-shaped section components need to be connected to the rectangular tube section, which increases the difficulty of the work. Utility Model Content
