[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 , Figure 2 as well as Figure 5 and Figure 6 As shown, the utility model provides a steel structure water pool, including: a top steel frame 1; a bottom steel frame 2, which is correspondingly arranged below the top steel frame 1; a bottom plate structure 3, which is laid on the top surface of the bottom steel frame 2; a vertical plate structure 5, whose bottom end is connected to the bottom plate structure 3, and the vertical plate structure 5 and the bottom plate structure 3 cooperate to form a water storage space; a column structure 4, including a plurality of columns, the top ends of the columns are connected to the top steel frame 1, and the bottom ends of the columns are connected to the bottom steel frame 2; wherein the bottom plate structure 3 has at least one preset arc 31, the plurality of columns include a plurality of arc-edge columns 41 arranged along the preset arc 31, and the vertical plate structure 5 has a curved wall structure 51 connected to the plurality of arc-edge columns 41.

[0033] The steel structure water pool of the utility model is provided with a top steel frame 1 and a bottom steel frame 2, and then a bottom plate structure 3 is laid on the bottom steel frame 2 to form a pool bottom, and a vertical plate structure 5 is provided to be connected with the bottom plate structure 3 to form a pool wall, and the top steel frame 1 and the bottom steel frame 2 are connected by a column structure 4, so as to ensure the overall stability of the steel structure water pool; further, at least one preset circular arc 31 is provided on the bottom plate structure 3, and a plurality of arc edge columns 41 are arranged along the preset circular arc 31, and then the vertical plate structure 5 is connected with the plurality of arc edge columns 41, so that the vertical plate structure 5 has at least one generally circular arc-shaped curved wall structure 51, so as to effectively improve the compression and deformation resistance of the pool wall.

[0034] Specifically, the bottom plate structure 3 includes a steel plate structure with an area larger than the design area of ​​the pool bottom, and the steel plate structure can be integrally formed or formed by splicing multiple steel plates. The top surface of the bottom plate structure 3 is its upper surface. In order to better describe the arrangement of multiple arc-edge columns 41 in the column structure 4, the present utility model defines at least one preset arc 31 on the bottom plate structure 3, rather than for limiting the contour shape of the bottom plate structure 3. Therefore, in one embodiment of the utility model, the preset arc 31 is the arc contour edge of the bottom plate structure 3. In another embodiment of the utility model, the contour shape of the bottom plate structure 3 can also be a rectangle, trapezoid or other shape without an arc contour edge, and the preset arc 31 can be an arc auxiliary line in the plane of the bottom plate structure 3. A plurality of arc side columns 41 are arranged along the preset arc 31, including the arc side columns 41 pressing the preset arc 31 (such as the first arc side column a, the third arc side column c, the fourth arc side column d, the fifth arc side column e and the sixth arc side column f in this embodiment) and / or the arc side columns 41 are arranged near the preset arc 31 (such as the second arc side column b in this embodiment). Figure 2 and Figure 3 As shown, the vertical plate structure 5 includes a plurality of vertical plates 53 arranged along its preset circumferential profile. The plurality of vertical plates 53 may be a flat steel plate with a rectangular cross section, connected with a plurality of arc-edge columns 41 to form a curved wall structure 51 similar to an arc; or the plurality of vertical plates 53 may be a curved steel plate with a fan-shaped cross section, connected with a plurality of arc-edge columns 41 to form a curved wall structure 51 in the shape of an arc.

[0035] like Figure 1 and Figure 2As shown, the ability of the curved wall structure 51 to resist compression and deformation is related to the number of the plurality of arc-side columns 41 and the arrangement positions of the plurality of arc-side columns 41. In the embodiment of the utility model, the plurality of arc-side columns 41 include a vertex column and at least one end column. The vertex column (such as the fifth arc-side column e in this embodiment) is located at the vertex of the preset arc 31, and the end column (such as the first arc-side column a and the sixth arc-side column f in this embodiment) is located at the end of the preset arc 31. In addition, a plurality of arc-side columns 41 (such as the second arc-side column b, the third arc-side column c and the fourth arc-side column d in this embodiment) are arranged between the vertex column and the end column, and the plurality of arc-side columns 41 are preferably evenly spaced and arranged.

[0036] In the embodiment of the utility model, an arc side column 41 is arranged every 15 to 40 degrees between the vertex column and the end point column, and preferably an arc side column 41 is arranged every 20 to 30 degrees. In addition, the ability of the curved wall structure 51 to resist compression and deformation is also related to the curvature of the preset arc 31. In the embodiment of the utility model, the curvature of the preset arc 31 is greater than 120 degrees. For example, in this embodiment, the curvature of the preset arc 31 is about 157.5 degrees, and an arc side column 41 is arranged every 22.5 degrees, with a total of 8 arc side columns 41 arranged.

[0037] like Figure 1 and Figure 2 As shown, since the arc-shaped curved wall structure 51 is more difficult to manufacture than the flat straight wall structure 52, in order to utilize the curved wall structure 51 of the vertical plate structure 5 to improve its ability to resist pressure and deformation, in the embodiment of the utility model, the base plate structure 3 also has at least one preset straight edge 32, and one end of at least one preset straight edge 32 is connected to one end of the preset arc 31, and the column structure 4 also includes at least one straight-side column 42 located on the preset straight edge 32, and the straight-side column 42 is connected to the vertical plate structure 5, so that part of the wall of the vertical plate structure 5 forms a straight-wall structure 52 with certain resistance to pressure and deformation.

[0038] like Figure 1 and Figure 2As shown, in order to improve the compression and deformation resistance of the vertical plate structure 5, the number of the preset arcs 31 and the curved wall structures 51 are both multiple, the multiple preset arcs 31 are connected, the multiple curved wall structures 51 are connected, at least one arc side column 41 is a connecting column, that is, the end column located at the end point of two adjacent preset arcs 31 is a connecting column (such as the sixth arc side column f in this embodiment), the connecting column is located at the connection of two adjacent preset arcs 31, and the two wing plates of the connecting column are respectively inclined along the tangent of the two adjacent preset arcs 31 and connected to the outer side surfaces of the two adjacent curved wall structures 51. As in the embodiment of the utility model, the opposite side walls of the vertical plate structure 5 are straight wall structures 52, one end of the two straight wall structures 52 is connected by two curved wall structures 51, and the other end of the two straight wall structures 52 is also connected by two curved wall structures 51.

[0039] like Figure 2 and Figure 3 As shown, in order to ensure that the supporting strength of the column meets the requirements, in the embodiment of the utility model, the column is generally a steel column structure made of H-shaped steel, including a web 411 and two wing plates arranged in the vertical direction, and the web 411 is connected between the two wing plates. Among them, the arc-edge column 41 and the straight-edge column 42 can be directly connected to the outer side of the vertical plate structure 5 through one of their wing plates, or can be connected to the outer side of the vertical plate structure 5 through a connecting structure 55. In addition, in order to further improve the compression and deformation resistance of the vertical plate structure 5, and at the same time facilitate the connection of the vertical plate structure 5 with the arc-edge column 41 and the straight-edge column 42, in the embodiment of the utility model, the vertical plate structure 5 also includes a plurality of purlins 54, and the plurality of purlins 54 are arranged along the preset circumferential contour of the vertical plate structure 5, and the plurality of purlins 54 are fixed to the outer side of the plurality of vertical plates 53, and the plurality of columns are connected between two adjacent purlins 54.

[0040] Specifically, the purlin 54 is generally a steel bar structure made of H-shaped steel, having an inner wing plate 542 arranged close to the vertical plate 53, an outer wing plate 543 arranged away from the vertical plate 53, and a web 541 connecting the inner wing plate 542 and the outer wing plate 543. The purlin 54 is welded to the outer side surface of the vertical plate 53 through its inner wing plate 542. The two wing plates of the column are respectively an inner wing plate 412 arranged close to the vertical plate 53 and an outer wing plate 413 arranged away from the vertical plate 53. The inner wing plates 412 and the outer wing plates 413 of the straight-edge column 42 and a part of the arc-edge column 41 are arranged perpendicular to their webs 411. In order to make the inner wing plates 412 of a part of the arc-edge column 41 better fit with the outer side surface of the vertical plate 53 and make it more firmly connected with the vertical plate structure 5, the inner wing plates 412 of the column can be tilted along the tangent direction of the preset arc 31, and then directly fit and weld the inner wing plates 412 to the outer side surface of the vertical plate 53.

[0041] like Figure 3As shown, the third arc side column c in this embodiment has two stiffening plates 414 connected to the inner wing plate 412 and the outer wing plate 413 on both sides of the web plate 411 of the third arc side column c, and the two stiffening plates 414 of the third arc side column c are connected to the web plates 541 of the two adjacent purlins 54 by fasteners such as bolts, and the inner wing plate 412 of the third arc side column c is flush with the inner wing plates 542 of the two purlins 54, and then the inner wing plate 412 is welded to the two adjacent vertical plates 53, and the two stiffening plates 414 are welded to the web plates 541 of the two adjacent purlins 54.

[0042] like Figure 3 and Figure 4 As shown, the second arc-edge column b in this embodiment, the inner side surface of the inner wing plate 412 of the second arc-edge column b away from its web 411 is connected to the web 541 of the two adjacent purlins 54 through a connecting structure 55, and the connecting structure 55 includes an upper connecting plate 551 and a lower connecting plate 552 spaced apart from each other, and in order to improve stability, a reinforcing plate 553 is vertically arranged on the upper connecting plate 551, and the webs 541 of the two adjacent purlins 54 are clamped between the upper connecting plate 551 and the lower connecting plate 552 and connected by fasteners such as bolts, and then the upper connecting plate 551 and the lower connecting plate 552 are welded to the inner wing plates 542 of the two adjacent purlins 54.

[0043] like Figure 5 As shown, in the embodiment of the utility model, the bottom steel frame 2 includes a base frame 21, and the base frame 21 includes a plurality of cross beams 211 and a plurality of first longitudinal beams 212, wherein the plurality of cross beams 211 are extended along a first horizontal direction X and arranged at intervals along a second horizontal direction Y perpendicular to the first horizontal direction X, and the plurality of first longitudinal beams 212 are extended along the second horizontal direction Y, and two adjacent cross beams 211 are connected by a plurality of first longitudinal beams 212 arranged at intervals along the first horizontal direction X. A mesh steel frame structure is formed by connecting the plurality of cross beams 211 and the plurality of first longitudinal beams 212, thereby supporting the bottom plate structure 3.

[0044] Combination Figure 1 and Figure 5As shown, in this embodiment, the shape of the circumferential profile of the base frame 21 is different from the shape of the circumferential profile of the bottom plate structure 3, and the size of the circumferential profile of the base frame 21 is larger than the size of the circumferential profile of the bottom plate structure 3. The base frame 21 is generally a rectangular frame, the length of the crossbeam 211 of the base frame 21 is equal to the distance between the two preset straight edges 32 of the bottom plate structure 3, slightly less than the sum of the diameters of the two preset arcs 31, and the sum of the lengths of the multiple longitudinal beams arranged along the second horizontal direction Y of the base frame 21 is equal to the sum of the length of the preset straight edge 32 and the diameter of the preset arcs 31 at both ends. Therefore, in order to improve the stability of the connection between the bottom steel frame 2 and the top steel frame 1, the multiple columns of the column structure 4 also include multiple auxiliary columns 43 located in the peripheral area of ​​the bottom plate structure 3, and the auxiliary columns 43 are not connected to the vertical plate structure 5 but only connect the bottom steel frame 2 and the top steel frame 1. In another embodiment of the utility model, the shape and size of the circumferential profile of the base frame 21 can also be similar to the profile and shape of the bottom plate structure 3.

[0045] Combination Figure 2 and Figure 5 As shown, in an embodiment of the utility model, the bottom steel frame 2 also includes a reinforcement structure 22, which is located below the curved wall structure 51. The reinforcement structure 22 includes a plurality of oblique beams 221 and a plurality of second longitudinal beams 222. The plurality of second longitudinal beams 222 extend along the second horizontal direction Y and are arranged at intervals along the first horizontal direction X. The second longitudinal beam 222 is connected between two adjacent cross beams 211 and is connected to at least one arc-edge column 41.

By arranging the reinforcing structure 22 below the curved wall structure 51 , the supporting strength of the plurality of arc-edge columns 41 can be improved, thereby also providing the curved wall structure 51 with the ability to resist compression and deformation.

[0046] In order to ensure the stability of the connection between the column structure 4 and the basic frame 21, as many columns as possible should be connected to the intersection of the cross beam 211 and the first longitudinal beam 212, and then the oblique beam 221 and the second longitudinal beam 222 should be arranged according to the position of the arc-edge column 41 that is not connected to the intersection of the cross beam 211 and the first longitudinal beam 212. As in the present embodiment, the plurality of third arc edge columns c and the plurality of fourth arc edge columns d are not connected at the intersection of the horizontal beam 211 and the first longitudinal beam 212, but are located in an internal space enclosed by two adjacent horizontal beams 211 and two adjacent first longitudinal beams 212. Therefore, in order to improve the stability of the plurality of third arc edge columns c and the plurality of fourth arc edge columns d, a plurality of first oblique beams i are provided to connect the plurality of columns (such as the second arc edge columns b, the sixth arc edge columns f or the auxiliary columns 43) connected at the intersection of the horizontal beam 211 and the first longitudinal beam 212 with the plurality of third arc edge columns c, and a plurality of second oblique beams j are provided to connect the plurality of third arc edge columns c with two adjacent horizontal beams 211. In addition, a plurality of second longitudinal beams 222 are provided to connect between two adjacent horizontal beams 211 and to the plurality of fourth arc edge columns d, and a plurality of third oblique beams k are provided to connect the plurality of first longitudinal beams 212 with two adjacent horizontal beams 211.

[0047] like Figure 5 As shown, in order to improve the supporting strength of the bottom steel frame 2 and to improve the compression and deformation resistance of the bottom plate structure 3, the internal space of the bottom steel frame 2 located below the bottom plate structure 3 is filled with concrete.

[0048] Combination Figure 5 and Figure 6 As shown, the structure of the top steel frame 1 is the same as that of the bottom steel frame 2, but the internal space is not filled with concrete. In addition, if a walking platform is required, a top plate structure is laid on the top surface of the top steel frame 1 to form a walking platform. If a walking platform is not required, there is no need to set a top plate structure on the top surface of the top steel frame 1.

[0049] The above are only several embodiments of the present invention.
