[0002] In recent years, a new trend of high-tech, composite and integrated products has been set off in my country's ecological and environmental protection industry. Prefabricated steel structure pools or prefabricated steel structure pool water treatment facilities have quickly gained wide recognition in the market due to their high flexibility, high degree of modularization and standardization, high degree of industrialization, short construction period, easy transportation, rapid disassembly and assembly, and reusability.

[0003] Prefabricated water plants are a new type of water plant construction model developed by the water and environmental protection industry to implement the concept of green and low-carbon development based on "engineering productization, product modularization, and module standardization". Prefabricated water plants replace the traditional reinforced concrete on-site construction model with a factory prefabrication and on-site assembly construction model. With its advantages of reducing land occupation by 60%, shortening construction time by 80%, reducing carbon emissions by 70%, and being 100% recyclable, it has developed rapidly.

[0004] However, it is inevitable that the joints between the assembled modules and the columns of the prefabricated water plant are prone to become weak links for leakage under the impact of water pressure and water flow. Therefore, how to provide a water pool side column connection node with good sealing performance has become a technical problem that needs to be solved urgently in the industry. Summary of the invention

[0005] The purpose of the present invention is to provide a hydraulically sealed connection node for side columns of an assembled steel structure water pool to solve the technical problems described in the background technology.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: A hydraulically squeezed side column sealing connection node of an assembled steel structure pool comprises a wall panel unit, a steel column and a rubber sealing pad, wherein the wall panel unit comprises a wall panel surface and a wall panel side column, wherein the wall panel side column is arranged along the vertical edge of the wall panel surface, the wall panel side column is connected and fixed to the vertical edge of the wall panel surface by welding, and the joint between the two is sealed by continuous welding; The steel column is arranged between the two wall panel units, and its cross-section is a trapezoidal cross-section with one end larger than the other end, and its small head end is arranged on the water-facing side close to the pool. The side of the wall panel side column close to the steel column is an inclined surface matching the side of the steel column. A rubber sealing pad is arranged between the wall panel side column and the steel column, and the cross-section of the rubber sealing pad is a T-shaped cross-section. The wall panel side column, the rubber sealing pad and the steel column are connected and fixed by high-strength bolts to achieve joint sealing. The high-strength bolts are arranged on the column on the water-receiving side of the wall panel side column, and the wall panel unit and the steel column are compacted and reinforced by the water pressure in the pool.

[0007] Preferably, the rubber sealing gasket includes a web and a wing plate which are integrally connected, the web is located in the joint between the wall panel side column and the steel column, the wing plate is thick in the middle and thin at both ends, the joint between the web and the wing plate is an arc chamfered structure, and the parts where the wall panel side column and the steel column are connected to the joint between the web and the wing plate are all arc chamfered structures that match them.

[0008] Preferably, the steel column includes a steel column body, a limiting flange is provided at the edge position of the large head end of the steel column body, the limiting flange extends to the outside of the steel column body and folds back to form a groove structure, and the wall panel side column includes a side column body, the end of the side column body extends beyond the wall panel surface to form a supporting flange inserted into the groove structure.

[0009] Preferably, one end of the side column body close to the pool extends beyond the outer side of the wall panel surface to form a bent flange, and the bent flange is bent toward a side away from the steel column.

The present invention optimizes the cross-section of the rubber sealing gasket to a T-shaped cross-section design. The wing plate thereof, as the water-facing side, can have a tendency to move toward the inside of the joint under the action of water pressure, and can better fit the steel columns and wall panel side columns on both sides of the joint. At the same time, due to the mutual squeezing of the steel columns and the wall panel side columns, a tendency to move toward the outside of the pool will be simultaneously applied to the web of the rubber sealing gasket, thereby further tightening the wing plate of the rubber sealing gasket to fit the steel columns and wall panel side columns on both sides of the joint, thereby improving the waterproof sealing performance at the node.

[0019] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the present invention and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structures of various components of the embodiments of the present invention, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not used to limit the scope of the present invention. Figure 1-6 , the preferred embodiments of the present invention are further described in detail: like Figure 1-3 As shown, a preferred assembled steel structure pool water pressure squeezed side column sealed connection node of the present invention comprises a wall panel unit, a steel column 3 and a rubber sealing pad 5, wherein the wall panel unit comprises a wall panel surface 1 and a wall panel side column 2, wherein the wall panel side column 2 is arranged along the vertical edge of the wall panel surface 1, and the wall panel side column 2 is connected and fixed to the vertical edge of the wall panel surface 1 by welding, and the joint between the two is sealed by continuous welding; The steel column 2 is correspondingly arranged between the two wall panel units, and its cross section is a trapezoidal cross section with one end larger than the other end, and its small head end is arranged on the water-facing side close to the pool, and the side of the wall panel side column 2 close to the steel column 3 is an inclined surface matching the side surface of the steel column 2, and a rubber sealing pad 5 is arranged between the wall panel side column 2 and the steel column 3, and the wall panel side column 2, the rubber sealing pad 5 and the steel column 3 are connected and fixed by high-strength bolts 4 to achieve joint sealing, and the wall panel unit and the steel column 3 are compacted and reinforced by the water pressure in the pool. On this basis, in order to avoid the position where the high-strength bolts 4 are inserted to become a water seepage channel, the high-strength bolts 4 are arranged on the outside of the weld between the wall panel side column 2 and the wall panel surface 1, and by arranging the high-strength bolts 3 at the backwater position of the wall panel side column 2, the problem of direct contact between the bolt pores of the high-strength bolts 4 and the pool water is avoided. While ensuring that the wall panel side column 2 and the steel column 3 are connected into a stable whole, the problem that the bolt position is prone to become a potential seepage channel is fundamentally avoided; Among them, the height of the wall panel unit needs to match the height of the pool to be built, that is, in the vertical direction, only one complete wall panel unit is set at the same cross-sectional position to avoid the appearance of horizontal joints. The wall panel surface 1 of the wall panel unit preferably adopts a corrugated wall panel to improve the bearing capacity of the wall panel unit. The corrugated wall panel can be a sinusoidal corrugated panel or a trapezoidal corrugated panel. According to the width of the corrugated panel and the height of the pool to be built, the wall panel unit can be divided into two types according to the direction of the waveform: horizontal row of wall panels (that is, the peak and trough lines extend horizontally) or vertical row of wall panels (that is, the peak and trough lines extend vertically). Arrangement method, of course, the wall panel unit should at least include a wall panel side column 2 arranged along the vertical edge of the wall panel surface 1 to match the steel column 3 for connection and fixation. At the same time, according to the stress conditions of different pools to be built, the wall panel unit can also further include a wall panel side beam arranged along the transverse edge of the wall panel surface 1 so that the entire wall panel unit can form a better frame stress structure and improve the overall stress performance of the wall panel unit. At this time, since the wall panel side beam at the transverse edge position does not have any restrictions on combination with the steel column 3, its cross-sectional form can be reasonably selected according to the stress analysis and the convenience of material acquisition; like Figure 1-3 , Figure 4As shown, in some preferred embodiments, the steel column 3 includes a steel column body 301, and a limiting flange 302 is arranged at the edge position of the large head end of the steel column body 301, and the limiting flange 302 extends to the outside of the steel column body 301 and folds back to form a groove structure, and the steel column body 301 is provided with a second bolt hole 303 at the position corresponding to the high-strength bolt 4, and the second bolt hole 303 is prefabricated in advance according to the module in the prefabrication stage to facilitate the insertion of the high-strength bolt 4 in the assembly construction stage. While ensuring the structural strength of the steel column body 301, in order to reduce the cost of steel materials and reduce the dead weight of the steel column 3 to facilitate production, transportation and installation construction, a cavity is arranged in the steel column body 301, and the cavity is provided with holes for adding Strengthening ribs for enhancing the strength of the column body. For example, the steel column body 301 is surrounded by three webs, namely, the front web (water-facing side), the left web and the right web. The three webs can be welded or integrally formed. A cavity is formed between the three webs. Strengthening ribs are welded at intervals in the cavity. The opening at the back can reduce the dead weight and save costs on the one hand, and can also provide sufficient operating space for the insertion of high-strength bolts 4 on the other hand. Of course, for the convenience of installation at the construction site, a base plate 6 is fixed to the bottom end of the steel column 3, and a third strip bolt hole 7 for inserting an anchor bolt is provided on the base plate 6. The third strip bolt hole 7 can be conveniently adjusted relative to the embedded anchor bolt during the installation stage to provide higher construction flexibility. like Figure 5 As shown, in order to cooperate with the steel column 3 to better achieve waterproof sealing, the wall panel side column 2 includes a side column body 201, and the end of the side column body 201 exceeds the wall panel surface 1 to form a supporting flange 203 inserted into the groove structure. The end of the supporting flange 203 is against the limiting flange 302 of the steel column 3, and cooperates with the high-strength bolt 4 to achieve the fixation of the wall panel unit to ensure the stability of the position of the wall panel unit and prevent the problem of excessive position displacement under the action of the water pressure in the pool. The side column body 201 is provided with a first bolt hole 204 at the position corresponding to the high-strength bolt 4. The first bolt hole 204 is formed in the prefabrication stage. It is prefabricated in advance according to the module to facilitate the insertion of high-strength bolts 4 during the assembly construction stage. At the same time, the end of the side column body 201 close to the pool exceeds the outer side of the wall panel surface 1 to form a bent flange 202, and the bent flange 202 is bent to the side away from the steel column 3. Through the bent flange 202, on the one hand, the weld between the wall panel surface 1 and the wall panel side column 2 can be effectively shielded and protected, avoiding direct impact and scouring of the water body in the pool, and further improving the sealing performance of the assembled steel structure pool. On the other hand, the bent flange 202 can also better cooperate with the wing plate 502 of the rubber sealing pad 5 to achieve joint sealing; like Figure 6As shown, the cross section of the rubber sealing pad 5 (for example, EPDM rubber can be used) is a T-shaped cross section, and the rubber sealing pad 5 includes a web 501 and a wing 502 connected in one piece, the web 501 is located in the joint between the wall panel side column 2 and the steel column 3, the wing 502 is thick in the middle and thin at both ends, the joint between the web 501 and the wing 502 is a circular arc chamfered structure, and the parts where the wall panel side column 2 and the steel column 3 are connected to the joint between the web 501 and the wing 502 are all circular arc chamfered structures matching therewith, that is, the bent part of the bent flange 202 of the wall panel side column 2 (that is, the bent flange 202) The root position) is set to a circular arc chamfer structure, and the arc contact mode combined with the wing plate 502 that is thick in the middle and thin at both ends can make the wing plate 502 better close to the wall panel side column 2 and the steel column 3 under the action of water pressure, and the edge position of the small head end of the steel column body 301 is also set to a circular arc chamfer structure. Of course, the structural form of the rubber sealing pad 5 can be further optimized, such as adding a raised waterproof line on the inner side of the wing plate 502, or setting the wing plate 502 to a round head structure with an arc chamfer and setting at least one hollow drum or protruding part on the web 501 in the cross-sectional direction to enhance the sealing and water-stopping effect; Based on the consideration of waterproof reinforcement, on the basis of bolted assembly, in order to increase more waterproof redundancy and avoid the problem of local failure and water seepage of the rubber sealing pad 5, in the waterproof design, in some preferred embodiments, a waterproof coating is added to the joint openings of the wall panel side column 2, the rubber sealing pad 5 and the steel column 3 on the water-facing side by spraying waterproof coating as a waterproof reinforcement layer to achieve secondary sealing.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
