DETAILED DESCRIPTION

[0064] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0065]

First embodiment

[0066] Figure 1 The frame structure diagram of the assembled cooling tower according to the present application.

[0067] As shown in Figure 1 , the assembled cooling tower frame 1000 includes a plurality of vertical columns 1100 arranged at intervals. Figure 1 The cooling tower frame in the prior art has a quadrangular prism structure, and the assembled cooling tower frame 1000 has an angle column 1110 at each of the four corners, including an angle column 1110a, an angle column 1110b, an angle column 1110c and an angle column 1110d.

[0068] It should be noted that, Figure 1The cooling tower frame 1000 in the embodiment is a quadrangular prism structure, but the present application is not limited thereto, and the cooling tower frame 1000 can also be a triangular prism structure, a pentagonal prism structure, a hexagonal prism structure, a heptagonal prism structure, and the like. According to the different external structures of the cooling tower, there are different numbers of corner columns 1110.

[0069] In combination with the coordinate system in the embodiment, along the X direction, three edge columns 1120a, 1120b and 1120c are arranged between the corner columns 1110a and 1110b. The corner column 1110a, the edge column 1120a, the edge column 1120b, the edge column 1120c and the corner column 1110b are sequentially and equally spaced. Figure 1 It should be noted that the number of the edge columns 1120 is not limited in the present application, and a person skilled in the art can set different numbers of edge columns 1120 according to the length and width of the cooling tower. The interval distance between the adjacent corner columns 1110 and the edge columns 1120 and the interval distance between the adjacent two edge columns 1120 can also be unequal.

[0070] In addition, in the embodiment, the columns arranged on the two sides in the length direction (along the X axis) of the cooling tower are symmetrical, and the columns arranged on the two sides in the width direction (along the Y axis) are also symmetrical, but they can also be arranged asymmetrically.

[0071] In the middle part of the cooling tower, three center columns 1130 are arranged, which are sequentially a center column 1130a, a center column 1130b and a center column 1130c. Along the X axis direction, the center column 1130a corresponds to the position of the edge column 1120a, the center column 1130b corresponds to the position of the edge column 1120b, and the center column 1130c corresponds to the position of the edge column 1120c. Along the Y axis direction, the positions of the center columns 1130a, 1130b and 1130c all correspond to the position of the edge column 1120d.

[0072] As viewed from above, the columns 1100 are arranged in an array, but the present application is not limited thereto.

[0073] The columns 1100 in part of the prior art are connected with the foundation by bolts and nuts, and then the processes of molding, grouting, curing, demolding and the like are performed to form the foundation of the columns, and the subsequent construction can be performed only after the concrete is completely cured, so that the construction period is long.

[0074]

[0075] In order to Figure 2 In the enlarged view A in the embodiment, Figure 1 In the monument type foundation external view in which the column 1100 is connected with the foundation, it is shown that the column 1100 is connected with the foundation by the bolts and nuts. Figure 2 Figure 3 ​A manufacturing process schematic view of the monument type foundation of one embodiment of the assembled cooling tower according to the utility model.

[0076] As Figure 3 As shown in (a), first, a pit 1310 for installing the column 1100 is prepared in the foundation. In order to adjust the verticality, horizontal position and height position of the column 1100, the applicant of the utility model designs an adjusting system. The adjusting system may, for example, include a pad 1330 arranged in a stack at the bottom of the pit, and the height of the pit bottom is adjusted by adjusting the number of the pad 1330, so that the bottom surfaces of the plurality of columns 1100 are at the same height position. In addition, the bottom surface height of each column 1100 can also be adjusted by machining a pad 1330 of a specific thickness. In the present application, the number of the pad 1330 is not limited, and can be one or more.

[0077] As Figure 3 As shown in (b), the bottom of the column 1100 is placed in the pit 1310. At this time, the column may not be in a vertical state, and the projection position of the column 1100 at the bottom of the pit 1310 also does not correspond to the positions of the other columns 1100. Therefore, it is necessary to adjust the verticality and horizontal position of the column 1100. First, the column 1100 is adjusted to be in a vertical state. Second, the column 1100 is adjusted so that the projection position of the column 1100 at the bottom of the pit 1310 corresponds to the positions of the other columns 1100, i.e. arrayed.

[0078] As Figure 3 As shown in (c), the verticality of the column 1100 is adjusted by the adjusting system 1320a.

[0079] As Figure 3 As shown in (d), after the verticality and position of the column 1100 are adjusted, the manufacturing of the monument type foundation 1300 is completed through the processes of molding, grouting, curing and demolding.

[0080] Figure 4 A structure schematic view of the adjusting system of one embodiment of the assembled cooling tower according to the utility model. Figure 5 A structure schematic view of the adjusting assembly of the first embodiment of the assembled cooling tower according to the utility model.

[0081] As Figure 3 and Figure 4 As shown in (a), four adjusting assemblies are arranged around the lower end of the column 1100 to form a group of adjusting units. The adjusting system includes a plurality of adjusting units arranged in a stack and spaced in the up-down direction.

[0082] For example, the adjusting system 1320a includes eight adjusting assemblies, Figure 4 which are shown in (b). Figure 2A cross-sectional view along the YOZ plane. In this plane of section, the adjustment assemblies 1320a1, 1320a2, 1320a3, 1320a4 are shown. In addition, as shown in Figure 2 the same four adjustment assemblies are also present when the column 1100 is sectioned along a mid-plane parallel to the XOZ plane.

[0083] The following is an example of how the plumbness of the column 1100 is adjusted by the adjustment system 1320a. For example, as shown in Figure 4 the column 1100 is in a tilted state, with its centerline CC" having an angle with the plumb line CC'. In order to deflect the column 1100 in the direction indicated by the arrow P, the lengths of the adjustment assemblies 1320a1, 1320a4 can be shortened, and the lengths of the adjustment assemblies 1320a2, 1320a3 can be lengthened.

[0084] The following is an example of how the horizontal position of the column 1100 is adjusted by the adjustment system 1320a. For example, the centerline of the column 1100 is at the EE' position, and in order to move the centerline of the column 1100 from EE' to the CC' position, the right movement of the column 1100 can be achieved by lengthening the lengths of the adjustment assemblies 1320a1, 1320a2, and shortening the lengths of the adjustment assemblies 1320a3, 1320a4.

[0085] The plumbness and position of the column 1100 can be conveniently adjusted by the adjustment system 1320a, and the adjustment has high precision.

[0086] Figure 5 A structural schematic view of the adjustment assembly according to the first embodiment of the assembled cooling tower of the present application.

[0087] As shown in Figure 5 , the adjustment assembly comprises adjustment plates A1, A2, and an adjustment screw A3. The adjustment screw A3 comprises a first threaded section A31, a second threaded section A32, and an operating portion A33. The threads of the first threaded section A31 and the second threaded section A32 are opposite in direction. The first threaded section A31 is connected to a threaded hole on the adjustment plate A1, and the second threaded section A32 is connected to a threaded hole on the adjustment plate A2. By rotating the adjustment screw A3, the distance between the adjustment plate A1 and the adjustment plate A2 can be increased or decreased.

[0088] In other embodiments, the adjustment assembly comprises an adjustment plate A1 and an adjustment screw A3 (not shown), which are threadedly connected. By rotating the adjustment screw A3, the adjustment assembly can be lengthened or shortened.

[0089] In order to facilitate the rotation of the adjusting screw A3, an operation part A33 is arranged on the adjusting screw A3, which can be a through hole or a hexagonal shape, facilitating the rotation of the adjusting screw A3 by a tool.

[0090] Figure 6 The adjusting system of the second embodiment of the assembled cooling tower according to the present application. Figure 7 The adjusting system of the second embodiment of the assembled cooling tower according to the present application.

[0091] As Figure 6 and Figure 7 As shown in FIGS. 1, 2 and 3, the adjusting system 1320b of the present embodiment includes adjusting assemblies 1320b1, 1320b2, 1320b3 and 1320b4. The adjusting assemblies of the present embodiment include a first wedge-shaped block B1, a second wedge-shaped block B2 and a third wedge-shaped block B3. The upper part of the third wedge-shaped block B3 is wider than the lower part, a first inclined surface B31 is formed on one side of the third wedge-shaped block B3, and a second inclined surface B32 is formed on the other side of the third wedge-shaped block B3.

[0092] One side of the first wedge-shaped block B1 is a vertical plane B21, and the other side is a third inclined surface B11 with an inclination suitable for the first inclined surface B31. One side of the second wedge-shaped block B2 is a vertical plane B22, and the other side is a fourth inclined surface B21 with an inclination suitable for the second inclined surface B32.

[0093] In use, the third wedge-shaped block B3 is wedged into the space between the first wedge-shaped block B1 and the second wedge-shaped block B2. The length of the adjusting assembly is adjusted by adjusting the depth of the third wedge-shaped block B3.

[0094] In addition, the number of wedge-shaped blocks of the adjusting assembly of the present embodiment is not limited, and can be two, four or more, as long as part of the adjacent wedge-shaped blocks are connected by wedge-shaped surfaces.

[0095] The working mode of the adjusting system 1320b of the present embodiment is similar to that of the adjusting system 1320a, and both are used to adjust the horizontal position and sag of the column 1100 by increasing or decreasing the length of the adjusting assembly, which will not be described here.

[0096] It should be noted that the inner contour of the recess 1310 in the present embodiment is a quadrangular prism, and the present application does not make special limitations on this, and the inner contour of the recess can also be a cylindrical shape, a triangular prism, a pentagonal prism, a hexagonal prism or other shapes.

[0097] After the adjustment of the height position, horizontal position and sag of the column 1100 is completed, the molding, grouting, curing and demolding work are carried out. In the technical scheme of the monument type foundation 1300 of the application, the adjusting system can play a supporting role on the column 1100, in addition, the structure of the monument type foundation 1300 fills the remaining space of the pit 1310 with concrete, which utilizes the characteristics that the compressive strength of concrete is greater than the tensile strength. Based on the above two points, the subsequent construction can be carried out without waiting for the concrete to be cured to a higher strength, which greatly shortens the construction time of the whole cooling tower.

[0098] The second embodiment

[0099] In the connection structure of the cross beam and the column of some existing prefabricated cooling towers, a protrusion (commonly known as "corbel") is arranged on the column below the connection, which is used to support the cross beam, and the connection of the cross beam and the column is realized by pre-burying bolts or nuts on the column. In order to prevent the metal connecting piece from rusting and improve the strength of the connection, concrete is usually poured at the connection of the column and the cross beam. During construction, a formwork needs to be made to wrap the connection, and after grouting and curing of the concrete, the formwork is removed. The construction period is long, which seriously delays the progress of the project.

[0100] In addition, from the perspective of stress analysis, the connection structure realizes the connection through metal pieces pre-buried in the column and the cross beam. Since the tensile capacity of concrete is small, the above connection method has weak strength.

[0101] The present inventors have revolutionarily solved the above technical problems through continuous research and testing. A quick and high-strength mortise and tenon connection structure between the column 1100 and the cross beam 1200 is proposed, which greatly speeds up the construction speed and shortens the overall construction period.

[0102] Figure 8 For Figure 1 is a partial enlarged view B of Figure 9 is a partial enlarged view C of Figure 1 . Figure 10 is a partial enlarged view D of Figure 1 .

[0103] As shown in Figure 8 , the mortise and tenon connection structure is applied to an angle column 1110 and a straight beam 1210 structure schematic diagram. Two straight beams 1210 are arranged at an angle, and mortise structures 1140 are formed on the adjacent two side walls of the column 1110. Tenon structures 1240 are formed at the end of the straight beam 1210, and the tenon structures 1240 are connected with the mortise structures 1140.

[0104] In addition, the tenon structure 1240 and the mortise structure 1140 can be interchanged, that is, the tenon structure 1240 can also be formed on the side of the column 1100; correspondingly, the mortise structure 1140 can also be formed at the end of the beam 1200.

[0105] like Figure 9 As shown, this mortise and tenon joint structure is applied to the connection structure between the side column 1120 and the straight beam 1210. Three straight beams 1210 are connected to the side column 1120 respectively. Adjacent straight beams 1210 are spaced apart by an included angle, preferably 90°.

[0106] like Figure 10 The diagram shows the mortise and tenon joint structure applied to the connection between the central column 1130 and the straight beam 1210. Four straight beams 1210 are connected to the central column 1130. Adjacent straight beams 1210 are spaced at an included angle, preferably 90°.

[0107] Figure 11 This is a schematic diagram of the structure of the column in the assembled cooling tower according to this utility model.

[0108] like Figure 11 As shown, column 1100 can be, for example, Figure 11 The corner prism 1110 shown in (a) Figure 11 (b) shows the side post 1120 and Figure 11 The structure of the central column 1130 is shown in (c).

[0109] The following is based on Figure 12 The corner prism 1110 shown in (a) is used as an example for explanation.

[0110] The corner post 1110 has a first support segment 1101 and a second support segment 1102 arranged vertically. The lower end of the second support segment 1102 is connected to the upper end of the first support segment 1101. Furthermore, the horizontal cross-sectional area of ​​the first support segment 1101 is larger than that of the second support segment 1102. Since the first support segment 1101 is located below the second support segment 1102, the weight it needs to support is greater than the weight of the second support segment 1102. Therefore, setting the cross-sectional area of ​​the first support segment 1101 to be larger than that of the second support segment 1102 allows for a more reasonable load distribution within both segments. Reducing the cross-sectional area of ​​the second support segment 1102 reduces material consumption, lightens weight, and also reduces the force it exerts on the first support segment 1101.

[0111] A boss 1103 is provided on the lower outer surface of the first support section 1101, and the boss 1103 is provided with a reinforcing rib 1106 extending upward.

[0112] A plurality of dovetail structures 1140 are provided on the first support section 1101 and the second support section 1102, and the dovetail structures 1140 are used to connect with the cross beam 1200.

[0113] Figure 11 For Figure 12 is a partial enlarged view E of the dovetail structure.

[0114] As Figure 13 shown, the dovetail structure 1140 includes a lateral boss 1141 protruding horizontally from the side surface of the column 1100. A groove 1142 is provided on the upper portion of the lateral boss 1141. The groove 1142 extends downward from the top surface of the lateral boss 1141 and does not penetrate the lateral boss 1141, and a support surface 1146 is formed at the bottom of the groove 1142. The groove 1142 extends horizontally from the column 1100 to form a lateral opening. That is, the groove 1142 has two open openings in the upper and lateral directions.

[0115] When viewed horizontally from the column 1100, the groove 1142 has an expanded portion 1143 and a contracted portion 1144, and the width (W1) of the expanded portion 1143 is greater than the width (W2) of the contracted portion 1144.

[0116] In addition, when viewed horizontally from the column 1100, the width (W3) of the lateral opening of the groove 1143 can be greater than the width (W2) of the contracted portion 1144 to form a flared portion 1145.

[0117] In addition, a reinforcing pin 1147 extending upward from the support surface 1146 is provided in the middle of the groove 1142. The reinforcing pin 1147 can be, for example, a steel bar with a lower end preformed in the lateral boss 1141.

[0118] Figure 14 is a structural schematic view of a cross beam in a fabricated cooling tower according to the present application. Figure 13 is a schematic view of a dovetail structure.

[0119] As Figure 13 shown in (a), the straight beam 1210 is provided with a dovetail structure 1240 at each end in the length direction. As Figure 14 shown in (b), the curved beam 1230 is provided with a dovetail structure 1240 at each end in the length direction.

[0120] As Figure 12As shown, in some embodiments, the tenon structure 1240 includes an expansion portion 1241 formed at its end, and a neck 1242 is provided between the expansion portion 1241 and the body of the crossbeam 1200. The horizontal width of the neck 1242 is smaller than the horizontal width of the expansion portion 1241. In this embodiment, the horizontal width of the neck 1242 is smaller than the horizontal width of the body of the crossbeam 1200. In other embodiments, the horizontal width of the body of the crossbeam 1200 may be the same as the horizontal width of the neck 1242.

[0121] Furthermore, the tenon structure 1240 also includes a longitudinally extending through hole 1243 formed in the middle of the width direction near the neck 1242, the position of which is related to... Figure 15 The position of the reinforced pin 1247 corresponds to this.

[0122] Figure 15 This is a schematic diagram of the mortise and tenon connection structure in the first embodiment of the assembled cooling tower according to the present invention.

[0123] like Figure 15 As shown, the column 1100 and the beam 1200 are connected quickly and with high strength through this mortise and tenon joint structure. Specifically, the tenon structure 1240 at the end of the beam 1200 is inserted into the groove 1142 on the lateral protrusion 1141 of the column 1100. The outer contour of the tenon structure 1240 matches the shape of the groove of the mortise structure 1140, and a gap exists between the tenon structure 1240 and the mortise structure 1140 to form a first grouting space G1. Preferably, sealing materials D1 and D2 are provided at the horizontal edge of the first grouting space G1 away from the mortise structure 1140 to seal the vertical gap at that edge.

[0124] In addition, from Figure 16 As can be seen, the width of the expansion portion 1241 of the tenon structure 1240 in the horizontal direction is greater than the width of the contraction portion 1144 of the mortise structure 1140 in the horizontal direction.

[0125] The reinforcing pin 1147 on the mortise structure 1140 is inserted into the through hole 1243 of the tenon structure 1240, forming a second grouting space G2 between the reinforcing pin 1147 and the through hole 1243.

[0126] First, after placing the tenon structure 1240 into the mortise structure 1140, before grouting, grouting can be performed simply by sealing the vertically extending gaps in the first grouting space G1, which is horizontally away from the edge of the mortise structure, using sealing materials D1 and D2. Sealing materials D1 and D2 can be made of foam, wood, or other materials, and can be cured into the mortise and tenon connection structure, eliminating the need for mold making and demolding, thus saving time. The second grouting space G2 can be directly filled with concrete or other filling materials without the need for mold making.

[0127] Secondly, the first grouting space G1 and the second grouting space G2 mentioned above only require a small amount of concrete to fill, allowing for flexible grouting methods during construction and increasing the grouting speed. The curing time required for the small amount of concrete is also relatively short.

[0128] Furthermore, the aforementioned mortise and tenon connection structure allows for a rapid and stable connection between the crossbeam 1200 and the column 1100, enabling subsequent construction to proceed without waiting for the poured concrete to fully cure, thus saving the overall construction time of the cooling tower.

[0129] Therefore, the mortise and tenon connection structure described above can significantly improve the construction efficiency of cooling towers, save construction time, and improve the overall strength of cooling towers, and has broad prospects for promotion and application.

[0130] Figure 16 This is a schematic diagram of the mortise and tenon connection structure in the second embodiment of the assembled cooling tower according to this utility model. Figure 17 In the middle, the horizontal width of the main body of the crossbeam 1200 is the same as the horizontal width of the neck 1242.

[0131] Figure 18 This is a schematic diagram of the mortise and tenon connection structure of the third embodiment of the assembled cooling tower according to the present invention. The schematic diagram is a cross-section cut along the horizontal direction. Figure 17 This is a longitudinal sectional view of the mortise and tenon connection structure in the third embodiment of the assembled cooling tower according to the present invention.

[0132] like Figure 18 As shown, in the mortise and tenon connection structure of this embodiment, the mortise structure 1140 has a through hole 1148 that passes horizontally through the lateral protrusion 1141. The tenon structure 1240 has a through hole 1243 corresponding to the through hole 1148, and the through hole 1243 extends horizontally and passes through the tenon structure 1240.

[0133] After the tenon structure 1240 is installed into the groove 1142 of the mortise structure 1140, the through hole 1148 is aligned with the through hole 1243. After the reinforcing pin 1147 is placed in the through hole 1148 and the through hole 1243, grouting is performed.

[0134] In this embodiment, after grouting is completed, both ends of the reinforcing pin 1147 are solidified together with the lateral protrusion 1141, which has a higher connection strength compared to the longitudinal arrangement.

[0135] like Figure 19 As shown, in this embodiment, the support surface 1146 is inclined and gradually rises from near the column 1100 to away from the column 1100. The bottom surface of the tenon structure 1240 has a structure adapted to the support surface 1146. The inclined support surface 1146 also serves to strengthen the connection strength of the mortise and tenon joint structure.

[0136] Figure 20 This is a longitudinal sectional view of the mortise and tenon connection structure according to the fourth embodiment of the prefabricated cooling tower of this utility model. In this embodiment, the support surface 1146 can also be a horizontal plane.

[0137] Figure 20 This is a schematic diagram of the pin structure in one embodiment of the assembled cooling tower according to the present invention.

[0138] like Figure 21 As shown, the reinforcing pin 1147 has a first end and a second end disposed opposite to each other, and a support portion 11471 for supporting the reinforcing pin 1147 is fixedly provided at the first end and the second end respectively. When the reinforcing pin 1147 is placed into the through hole 1243 and the through hole 1148, the support portion 11471 can support the reinforcing pin 1147, keeping the reinforcing pin 1147 in the center position of the through hole 1243. The number of the support portions 1147 is not particularly limited, as long as they can support the reinforcing pin 1147. The support portion 11471 can be, for example, four cylinders evenly distributed around the reinforcing pin 1147 and extending radially, or a ring structure connected to the reinforcing pin 1147 as a whole, etc.

[0139] Figure 21 A perspective view of the wall panel fixing structure 1400 of the prefabricated cooling tower according to this utility model.

[0140] like Figure 22 As shown, a cooling tower wall panel fixing structure 1400 includes an inner bracket 1410 located outside a column 1100 of a cooling tower 1000; and an outer bracket 1420 fastened to the inner bracket 1410, with a slot 1460 formed between the outer bracket 1420 and the inner bracket 1410 for accommodating the edge of a wall panel 1430. The cooling tower wall panel fixing structure 1400 also includes a fastener 1450 passing through the outer bracket 1420 and connecting to the column, the fastener 1450 clamping the edge of the wall panel 1430 between the outer bracket 1420 and the inner bracket 1410.

[0141] The cooling tower wall plate fixing structure 1400 has unique advantages in the process of assembling the cooling tower. After the internal construction of the cooling tower is completed, the wall plate is fixed in at least one direction through the clamping groove 1460 between the outer support 1420 and the inner support 1410, which is convenient and fast for construction, and greatly improves the construction speed of the cooling tower.

[0142] The clamping groove 1460 is symmetrically formed on both sides of the width direction of the inner support 1410 and the outer support 1420. Thus, the wall plate 1430 on both sides can be supported, and the production cost is reduced. However, at the corner position of the cooling tower, the clamping groove 1460 can be formed on only one side of the width direction of the wall plate fixing structure 1400.

[0143] As a preferred, the wall plate fixing structure 1400 further comprises a support frame 1440 fixedly connected with the column 1100 and supported on the lower side of the wall plate 1430. The support frame 1440 can be made of angle iron, channel steel or the like section bar. The two ends of the support frame 1440 are fixedly connected with the columns 1100 on both sides, respectively. The two ends of the support frame 1440 can also be connected with the inner supports 1410 on both sides, respectively.

[0144] Figure 22 The structure diagram of the inner support 1410.

[0145] As shown in Figure 23 The inner support 1410 has an inner bottom plate 1411, and a first guide plate 1412 and a second guide plate 1413 connected with the inner bottom plate 1411. The first guide plate 1412 and the second guide plate 1413 are both perpendicular to the inner bottom plate 1411, and the extension directions of the first guide plate 1412, the second guide plate 1413 and the inner bottom plate 1411 are the same. The first guide plate 1412 and the second guide plate 1413 are arranged at intervals. The first guide plate 1412 is arranged at an interval from the edge on one side of the width direction of the inner bottom plate 1411, and the second guide plate 1413 is arranged at an interval from the edge on the other side of the width direction of the inner bottom plate 1411.

[0146] In the above-mentioned inner support 1410, the inner bottom plate 1411 can be connected with the column 1100 by screws or the like. The first guide plate 1412 and the second guide plate 1413 are arranged at intervals from the edges on both sides of the width direction of the inner bottom plate 1411, respectively, thereby providing space for forming the clamping groove 1460.

[0147] Figure 24 The structure diagram of the outer support 1420.

[0148] The outer support 1420 has an outer bottom plate 1421 and third and fourth guide plates 1422 and 1423 connected with the outer bottom plate 1421; the third and fourth guide plates 1422 and 1423 are perpendicular to the outer bottom plate 1421, and the third and fourth guide plates 1422 and 1423 and the outer bottom plate 1421 have the same extension direction; the third and fourth guide plates 1422 and 1423 are arranged at intervals; the third guide plate 1422 is arranged at an interval from one side edge of the outer bottom plate 1421 in the width direction, and the fourth guide plate 1423 is arranged at an interval from the other side edge of the outer bottom plate 1421 in the width direction.

[0149] When the outer support 1420 and the inner support 1410 are buckled and connected, the first and second guide plates 1412 and 1413 are located between the third and fourth guide plates 1422 and 1423; or the third and fourth guide plates 1422 and 1423 are located between the first and second guide plates 1412 and 1413.

[0150] The connection between the first and second guide plates 1412 and 1413 and the third and fourth guide plates 1422 and 1423 can play a guiding role when the outer support 1420 and the inner support 1410 are connected, and can provide stable support for the wall plate 1430.

[0151] ​ It is a top view structural schematic diagram of the wall plate fixing structure 1400.

[0152] The surface of the column 1100 facing the outside of the cooling tower is pre-embedded with a pre-embedded part 1150, and a fastener 1450 is connected with the pre-embedded part 1150. The pre-embedded part 1150 is a nut or a bolt, which is pre-embedded in the inside of the column 1100 when the column 1100 is prefabricated.

[0153] In the fabricated cooling tower 1000, the wall plate fixing structure 1400 can quickly and firmly install the wall plate 1430 on the cooling tower, and greatly improves the construction speed of the cooling tower.

[0154] The above describes the preferred embodiment of the fabricated cooling tower structure of the present application in detail, but those skilled in the art can make various modifications, changes, combinations, etc. on the basis of the above, and these modifications, changes, combinations all fall within the protection scope of the claims of the present application.
