[0026] The drawings of the present application are schematic drawings that assist in explaining the concept of the present application, and schematically represent the shape of each part and its mutual relationship. 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.

[0027] 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 1-5 , the preferred embodiment of the present application will be described in detail:

[0028] As Figures 1-2 shown, the preferred assembled steel structure pool side column node structure of the present application comprises a wall plate unit 1 and a steel column 2, the wall plate unit 1 comprises a wall plate surface 101 and a wall plate side column 102, the wall plate side column 102 is arranged along the vertical edge of the wall plate surface 101, the wall plate side column 102 and the vertical edge of the wall plate surface 101 are connected and fixed in a welded manner, and the joint of the two is sealed by continuous welding;

[0029] The wall plate edge column 102 is in the form of an angle steel, the web plate of which is welded and fixed with the wall plate surface 101, and the flange thereof extends in the direction away from the wall plate surface 101 on one side in the pool. The steel column 2 is in the form of an I-shaped section column, and a plurality of column reinforcing plates 3 are fixed in the abdominal cavity of the steel column 2. The steel column 2 is arranged between two wall plate units 1. The wall plate edge column 102 of the wall plate unit 1 on both sides of the steel column 2 is arranged at the corner of the water side flange of the steel column 2. The web plate of the steel column 2 abuts and is fixedly connected with the outer edge of the column reinforcing plate 3. The flange of the wall plate edge column 102 is attached to the outer surface of the water side flange of the steel column 2 and is fixedly connected with the water side flange of the steel column 2 by a sealing connection. The steel column 2 and the two wall plate edge columns 102 connected on both sides thereof form an equivalent I-shaped section column with unequal flanges.

[0030] The height of the wall plate unit 1 needs to match the height of the pool to be built, that is, only one complete wall plate unit 1 is arranged at the same cross-sectional position in the vertical direction to avoid the appearance of horizontal joint seams. The wall plate surface 101 of the wall plate unit 1 preferably adopts a corrugated wall plate to improve the load-bearing capacity of the wall plate unit 1. The corrugated wall plate can be a sine wave plate or a trapezoidal wave plate. According to the width of the corrugated plate and the height of the pool to be built, the wall plate unit 1 can be arranged in a horizontal row (i.e., the wave peak and valley lines extend horizontally) or a vertical row (i.e., the wave peak and valley lines extend vertically). Of course, the wall plate unit 1 should at least include a wall plate edge column 102 arranged along the vertical edge of the wall plate surface 101 to cooperate with the steel column 2 to form an equivalent I-shaped section column with unequal flanges. In addition, according to the stress condition of different pools to be built, the wall plate unit 1 can further include a wall plate edge beam arranged along the horizontal edge of the wall plate surface 101 to form a more optimal frame stress structure and improve the overall stress performance of the wall plate unit 1. At this time, since the wall plate edge beam at the horizontal edge position is not limited to combination with the steel column 2, the cross-sectional form thereof can be reasonably selected according to stress analysis and material selection convenience.

[0031] Similarly, the specific sealing connection form of the joint seam in the middle of the equivalent I-shaped section column with unequal flanges also needs to be reasonably selected according to the construction conditions and construction requirements. For example, in some preferred embodiments, the joint between the flange of the wall plate edge column 102 and the flange of the steel column 2 and the joint between the web plate of the wall plate edge column 102 and the column reinforcing plate 3 can be fixedly connected by a through-welding seam. Of course, according to the stress requirements of different scenes, the position and number of the welding seams can be reasonably selected and arranged according to stress calculation.

[0032] As Figure 1As shown, in consideration of construction convenience, the need to reduce or even avoid on-site fire operation, in some preferred embodiments, the edge of the column reinforcing plate 3 is fixedly provided with a force transmission connector 4 made of angle steel or steel plate, which abuts against the web of the wall plate edge column 102 and is connected and fixed by the first high-strength bolt 5, the flange of the wall plate edge column 102 and the water side flange of the steel column 2 are connected and fixed by the second high-strength bolt 6 penetrating the plate bodies of both, wherein the specific model and the setting number and setting interval of the first high-strength bolt 5 and the second high-strength bolt 6 are determined according to the specific stress analysis and calculation of different to-be-built projects, at this time, in order to ensure the waterproof performance of the joint, coordinate the stress deformation of the I-shaped cross-section composite column body with equivalent unequal-thickness flanges and the sealing for the pool structure, avoid water seepage through the gap, the rubber sealing gasket 8 is arranged along the vertical direction through the joint between the flange of the wall plate edge column 102 and the water side flange of the steel column 2, and the rubber sealing gasket 8 is fixed by the pre-tightening force of the second high-strength bolt 6, on this basis, in order to avoid the position where the first high-strength bolt 5 is arranged from becoming a water seepage channel, the first high-strength bolt 5 is arranged on the column body on the backwater side of the wall plate edge column 102, that is, with the weld between the wall plate edge column 102 and the wall plate surface 101 as the reference, the first high-strength bolt 5 is arranged on the wall plate edge column 102 on the outside of the weld (here, the side close to the pool is the inside, and the side away from the pool is the outside), by arranging the first high-strength bolt 5 on the backwater position of the I-shaped cross-section composite column body with equivalent unequal-thickness flanges, the problem of direct contact between the bolt hole gap of the first high-strength bolt 5 and the pool water is avoided, while ensuring that the wall plate edge column 102 and the steel column 2 are connected into a stable whole, the problem that the bolt position is easy to become a potential seepage channel is fundamentally avoided;

[0033] As Figure 2As shown, in order to optimize the possible water seepage problem of the second high-strength bolt 6 passing through the bolt position, in some preferred embodiments, the edge of the column reinforcement plate 3 is fixedly provided with a force transmission connector 4 made of angle steel or steel plate, which abuts against the web of the wall plate edge column 102 and is connected and fixed by the first high-strength bolt 5, the flange of the wall plate edge column 102 and the water side flange of the steel column 2 are connected and fixed by the third high-strength bolt 7 and the pressing plate 10, and the joint between the flange of the wall plate edge column 102 and the water side flange of the steel column 2 is provided with a rubber sealing gasket 8 along the vertical direction, a certain width is reserved between the angle steel flanges of the wall plate edge columns 102 on both sides of the steel column 2 as the welding position of the third high-strength bolt 7, one end of the third high-strength bolt 7 is welded and fixed on the outer facade of the water side flange of the steel column 2, and the setting position of the third high-strength bolt 7 corresponds to the web of the steel column 2, the pressing plate 10 is sleeved on the screw rod of the third high-strength bolt 7, and the two ends of the pressing plate 10 are respectively overlapped on the flanges of the wall plate edge columns 102 on both sides, and the pressing plate 10 is tightly fixed by the nut of the third high-strength bolt 7 to ensure the cooperative deformation of the steel column 2 and the wall plate edge columns 102 on both sides. Since the third high-strength bolt 7 is fixed in cooperation with the pressing plate 10, the flanges of the steel column 2, the flanges of the wall plate edge column 102 and the penetrating rubber sealing gasket 8, compared with the bolted and fixed form of the second high-strength bolt 6, the corresponding fixing mode of the third high-strength bolt 7 has better sealing performance, and further, the pressing plate 10 can be arranged in the form of being arranged along the joint, so that a sealing cavity is formed between the pressing plate 10 and the flanges of the steel column 2 and the flanges of the wall plate edge columns 102 on both sides. In order to better realize the sealing of the joint, the sealing cavity can be filled with polyurea waterproof coating;

[0034] Similarly, on the basis of bolted assembly, in order to improve the sealing and water stopping effect of the rubber sealing gasket 8, in some preferred embodiments, the rubber sealing gasket 8 is provided with at least one hollow or protruding part in the transverse direction, wherein the specific cross-sectional form of the rubber sealing gasket 8 includes but is not limited to the form as shown Figures 3-5 The hollow or protruding part is tightly fixed by the angle steel wall plate edge column 102 and the steel column 2;

[0035] Of course, during actual construction, the combination of bolting and welding can also be used, for example, in some preferred embodiments, on the basis of the above bolted assembly, further sealing and reinforcement can be realized by the form of through-welding at the joint between the wall plate edge column 102 and the steel column 2;

[0036] Based on the consideration of waterproof reinforcement, on the basis of bolted assembly, in order to increase more waterproof redundancy and avoid the possible failure of the rubber sealing gasket 8, the opening of the joint between the flange of the wall plate edge column 102 and the water side flange of the steel column 2 can be sealed again by a waterproof coating 9, that is, as Figure 1As shown, the waterproof coating 9 formed by spraying waterproof paint on the outer surface of the overlapping part of the wall plate edge column 102 angle steel flange and the steel column 2 flange near the pool side of the equivalent unequal-thickness flange I-shaped section composite column body serves as a waterproof reinforcing layer.

[0037] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
