[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figures 1-4 The preferred embodiments of this utility model will be described in further detail below:

[0028] like Figure 1 As shown, a preferred embodiment of the present invention is a prefabricated steel structure water tank side column connection node, including a wall panel unit 1 and a T-shaped steel column 2. The wall panel unit 1 includes a wall panel surface 101 and a wall panel side column 102. The wall panel side column 102 is arranged along the vertical edge of the wall panel surface 101. The wall panel side column 102 is connected and fixed to the vertical edge of the wall panel surface 101 by welding, and the joint between the two is sealed by continuous welding.

[0029] The wall panel edge column 102 is made of angle steel, with its web welded and fixed to the wall panel surface 101. Its flange extends from the inside of the pool towards the wall panel surface 101. The T-shaped steel column 2 is correspondingly set between two wall panel units 1. Its web extends into the joint between the two adjacent wall panel units 1 and is connected and fixed to the two wall panel edge columns 102 on both sides by a sealed connection. Its flange is set on the outside of the pool and its flange is parallel to the wall panel surface 101 of the adjacent wall panel unit 1. The T-shaped steel column 2 and the two wall panel edge columns 102 connected to its two sides are combined to form an equivalent I-shaped cross-section composite column with reasonable cross-sectional shape, good mechanical properties, and convenient construction.

[0030] The height of the wall panel unit 1 needs to match the height of the pool to be built, that is, in the vertical direction, only one complete wall panel unit 1 is arranged at the same cross-sectional position to avoid the appearance of horizontal joint seams, and the wall panel surface 101 of the wall panel unit 1 preferably adopts a corrugated wall panel to improve the load-bearing capacity of the wall panel unit. The corrugated wall panel can be a sinusoidal wave panel or a trapezoidal wave panel. According to the width of the corrugated wall panel and the height of the pool to be built, the wall panel unit 1 can be arranged in two ways, that is, the wall panel horizontal row (that is, the wave peak and trough line extends horizontally) or the wall panel vertical row (that is, the wave peak and trough line extends vertically) according to the direction of the corrugated wall panel. Of course, the wall panel unit 1 should at least include a wall panel edge column 102 arranged along the vertical edge of the wall panel surface 101 to cooperate with the T-shaped steel column 2 to form an equivalent I-shaped cross-section composite column. At the same time, according to the stress condition of different pools to be built, the wall panel unit 1 can further include a wall panel edge beam arranged along the horizontal edge of the wall panel surface 101 to form a more optimal frame stress structure for the entire wall panel unit 1, thereby improving the overall stress performance of the wall panel unit 1. At this time, since the wall panel edge beam at the horizontal edge position does not have the restriction of combination with the T-shaped steel column 2, its cross-sectional form can be reasonably selected according to stress analysis and material selection convenience angle;

[0031] Similarly, the specific sealing connection form of the joint seam existing in the middle of the equivalent I-shaped cross-section composite column also needs to be reasonably selected according to the construction conditions and construction requirements. For example, in some preferred embodiments, the wall panel edge column 102 and the T-shaped steel column 2 can be fixedly connected by a through-welding seam at the joint seam. According to the stress requirements of different scenes, the welding seam can be arranged on the water side alone, or according to the stress calculation, it can be arranged on both the water side and the backwater side;

[0032] In consideration of the convenience of construction, the need to reduce or even avoid on-site fire operation, in some preferred embodiments, the T-shaped steel column 2 is connected and fixed between the two wall plate edge columns 102 connected on both sides through high-strength bolts 3, wherein the specific model and setting number and setting interval of the high-strength bolts 3 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 equivalent I-shaped cross-section composite column body and the sealing for the pool structure, avoid water seepage through the gap, the T-shaped steel column 2 is arranged with rubber sealing pads 4 in the vertical direction along the length of the joint with the wall plate edge column 102, the rubber sealing pads 4 are pressed and fixed by the pre-tightening force of the high-strength bolts 3, on this basis, in order to avoid the position where the high-strength bolts 3 are arranged to become a water seepage channel, the high-strength bolts 3 are arranged on the outside of the weld between the wall plate edge column 102 and the wall plate surface 101, by arranging the high-strength bolts 3 in the backwater position of the equivalent I-shaped cross-section composite column body, the problem of direct contact between the bolt hole gap of the high-strength bolts 3 and the pool water is avoided, while ensuring that the wall plate edge column 102 and the T-shaped 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] Similarly, on the basis of bolted assembly, in order to improve the sealing and waterproof effect of the rubber sealing pad 4, in some preferred embodiments, the rubber sealing pad 4 is provided with at least one hollow or protruding part in the transverse direction, wherein the specific cross-sectional form of the rubber sealing pad 4 includes but is not limited to the form as shown in Figures 2-4 The hollow or protruding part of the rubber sealing pad 4 is pressed and fixed by the angle steel wall plate edge column 102 and the T-shaped steel column 2;

[0034] 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-mentioned bolted assembly, further sealing and reinforcement can be achieved by a through-weld joint at the joint between the wall plate edge column 102 and the T-shaped steel column 2;

[0035] Based on the waterproof reinforcing consideration, on the basis of the bolted assembly, in order to increase more waterproof redundancy, avoid the possible failure of the rubber sealing gasket 4 local water leakage problem, in the waterproof design, further increase the waterproof coating 5 at the joint position of the equivalent I-shaped cross-section composite column on the water side, that is, the flange outer surface of the equivalent I-shaped cross-section composite column near the pool side is covered by the waterproof coating 5 as a waterproof reinforcing layer, of course, in order to improve the waterproof effect of the waterproof coating 5 on the joint of the wall plate edge column 102 and the T-shaped steel column 2, a certain gap is left between the edge of the rubber sealing gasket 4 near the pool side and the flange outer surface of the equivalent I-shaped cross-section composite column near the pool side, and the gap is also filled and compacted by the waterproof coating 5, that is, the edge of the rubber sealing gasket 4 on the water side is designed to be recessed into the joint of the wall plate edge column 102 and the T-shaped steel column 2 by a certain distance, so that the waterproof coating 5 can penetrate into the joint of the wall plate edge column 102 and the T-shaped steel column 2 when spraying, thereby improving the bonding strength and local thickness of the waterproof coating 5 and the equivalent I-shaped cross-section composite column flange, so that the waterproof coating 5 is more difficult to appear the problems of peeling off and local damage.

[0036] The above only 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 principles of the present application shall be included in the protection scope of the present application.
