Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and in particular relates to a wall of a large transformer substation cabin formed by welding. Background Art

[0002] With the continuous development of society, the use of electrical equipment has become increasingly common, leading to the rapid development of power engineering. Existing substations and other core equipment are becoming increasingly common. Therefore, protecting these equipment has become increasingly important. Traditionally, protecting these equipment through building structures is time-consuming, labor-intensive, inefficient, and costly. Furthermore, wall structures constructed from directly welded steel plates, exposed to the elements outdoors for extended periods, often suffer from the inherent characteristics of the steel plates, shortening their service life and posing safety risks.

[0003] Currently, most commonly used substation protective structures are based on lightweight walls, such as metal-faced sandwich panels, often made of color-coated steel. Sandwich panels have high requirements for core material, and conventional core materials have poor fire resistance. Materials with good fire resistance are expensive to manufacture, and their environmental requirements are high, limiting their applicability. This ultimately results in a short service life, weak structural integrity, and poor fire resistance. Utility Model Content

[0029] In this embodiment, the corner piece 2 of the present invention is placed on an existing horizontal welding platform 1, and the corner piece 2 is welded to the main bearing steel. The existing horizontal welding platform 1 is set according to specific actual use needs.

[0030] The corner piece 2 is a rectangular structure with a length of 178 mm, a width of 162 mm and a height of 118 mm. There are four corner pieces 2 and they are symmetrically distributed in the shape of a "mouth". The corner piece 2 is provided with a first through hole 21, a second through hole 22 and a third through hole 23. The first through hole 21 is located at the top of the corner piece 2, the second through hole 22 and the third through hole 23 are respectively located on the sides of the corner piece 2, and the main bearing steel 3 is respectively provided in the second through hole 22 and the third through hole 23.

[0031] In this embodiment, the corner fittings 2 may also be standard universal corner fittings for containers, thereby increasing the practicality of the present invention.

[0032] The cross-sections of the first through hole 21 and the third through hole 23 of the corner piece are both elliptical structures, and the cross-section of the second through hole 22 of the corner piece is a shield-shaped structure.

[0033] The specific cross-sectional shapes of the first through hole 21 of the corner piece, the second through hole 22 of the corner piece, and the third through hole 23 of the corner piece can be set according to actual use needs, so as to better cooperate and connect with the main bearing steel 3.

[0034] The main bearing steel 3 is a channel steel, and the bottom width of the main bearing steel 3 is 200 mm. In this embodiment, the main bearing steel 3 is a standard 20# hot-rolled channel steel.
