Please note that in order to clearly show the structure of each component of the embodiments of the present application, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0032] The principles and features of the present application will be described below in conjunction with the drawings, and the examples are only used to explain the present application and are not intended to limit the scope of the present application. The preferred embodiments of the present application will be described in detail below: Figures 1-6 , the preferred embodiment of the present application will be described in detail:

[0033] As Figures 1-3 shown, the preferred embodiment of the present application is an assembled steel structure pool self-tightening type side column node structure, which comprises a wall plate unit, a steel column 3 and a rubber sealing gasket 5, the wall plate unit comprises a wall plate surface 1 and a wall plate side column 2, the wall plate side column 2 is arranged along the vertical edge of the wall plate surface 1, the wall plate side column 2 and the vertical edge of the wall plate surface 1 are connected and fixed in a welded manner, and the joint of the two is sealed by continuous welding;

In order to avoid the position of the high-strength bolt 4 from becoming a water seepage channel, the high-strength bolt 4 is arranged on the outside of the weld between the wall plate column 2 and the wall plate surface 1. By arranging the high-strength bolt 3 on the backwater position of the wall plate column 2, the problem of direct contact between the bolt hole gap and the pool water is avoided. While ensuring that the wall plate column 2 and the steel column 3 are connected into a stable whole, the problem of the bolt position being a potential seepage channel is fundamentally avoided.

[0035] The height of the wall plate unit needs to match the height of the pool to be built, that is, only one complete wall plate unit is arranged at the same cross-sectional position in the vertical direction to avoid horizontal joint seams. The wall plate surface 1 of the wall plate unit preferably adopts a corrugated wall plate to improve the load-bearing capacity of the wall plate unit. The corrugated wall plate can be a sinusoidal wave plate or a trapezoidal wave plate. According to the width of the wave plate and the height of the pool to be built, the wall plate unit can be arranged in a horizontal row (i.e., the wave crest and trough lines extend horizontally) or a vertical row (i.e., the wave crest and trough lines extend vertically) according to the wave direction. Of course, the wall plate unit should at least include a wall plate column 2 arranged along the vertical edge of the wall plate surface 1 to cooperate with the steel column 3 for connection and fixation. In addition, according to the stress condition of different pools to be built, the wall plate unit can further include a wall plate beam arranged along the horizontal edge of the wall plate surface 1 to form a more optimal frame stress structure and improve the overall stress performance of the wall plate unit. At this time, since the wall plate beam at the horizontal edge position does not have the restriction of combination with the steel column 3, its cross-sectional form can be reasonably selected according to stress analysis and material selection convenience.
