[0051] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0052]

First embodiment

[0053] Figure 1 The frame structure diagram of the assembled cooling tower according to the present application.

[0054] As Figure 1 shown, the assembled cooling tower frame 1000 includes a plurality of 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.

[0055] It should be noted that Figure 1 the cooling tower frame 1000 in the prior art has a quadrangular prism structure, but the present application is not limited thereto, and the cooling tower frame 1000 can also have a triangular prism structure, a pentagonal prism structure, a hexagonal prism structure, a heptagonal prism structure, etc. According to different external structures of the cooling tower, there are different numbers of angle columns 1110.

[0056] In combination Figure 1 with the coordinate system in the prior art, along the X direction, three edge columns 1120a, 1120b and 1120c are arranged between the angle columns 1110a and 1110b. The angle column 1110a, the edge column 1120a, the edge column 1120b, the edge column 1120c and the angle column 1110b are sequentially and equally spaced. Along the Y direction, one edge column 1120d is arranged between the angle column 1110a and the angle column 1110b. The angle column 1110a, the edge column 1120d and the angle column 1110b are sequentially and equally spaced.

[0057] It should be noted that the number of the above edge columns 1120 is not limited by 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 adjacent angle columns 1110 and edge columns 1120 and the interval distance between adjacent two edge columns 1120 can also be unequal.

[0058] In addition, in the present embodiment, the columns arranged on both sides of the length direction (along the X axis) of the cooling tower are symmetrical, and the columns arranged on both sides of the width direction (along the Y axis) are also symmetrical, but they can also be arranged asymmetrically.

[0059] Three central columns 1130 are located in the middle of the cooling tower: central column 1130a, central column 1130b, and central column 1130c. In the X-axis direction, central column 1130a corresponds to the position of side column 1120a, central column 1130b corresponds to the position of side column 1120b, and central column 1130c corresponds to the position of side column 1120c. In the Y-axis direction, the positions of central columns 1130a, 1130b, and 1130c all correspond to the position of side column 1120d.

[0060] From an overhead view, the columns 1100 are arranged in an array, but this application is not limited to this.

[0061] In some existing technologies, the column 1100 is connected to the foundation with bolts and nuts, and then the foundation is formed by processes such as molding, grouting, curing, and demolding. Subsequent construction can only be carried out after the concrete has completely cured, resulting in a long construction cycle.

[0062] Figure 2 for Figure 1 A magnified view of a portion of the image. Figure 2 The image shows the exterior of the monument-shaped foundation connecting column 1100 to the ground. Figure 3 This is a schematic diagram illustrating the manufacturing process of a monument-shaped foundation according to one embodiment of the prefabricated cooling tower of the present invention.

[0063] like Figure 3 As shown in (a), a recess 1310 for installing the columns 1100 is first prefabricated in the foundation. To adjust the verticality, horizontal position, and height of the columns 1100, the applicant of this utility model designed an adjustment system. This adjustment system may include, for example, shims 1330 stacked at the bottom of the recess. By adjusting the number of shims 1330, the height of the bottom of the recess is adjusted, thereby adjusting the bottom surfaces of multiple columns 1100 to be at the same height. Alternatively, shims 1330 of a specific thickness can be machined to adjust the bottom height of each column 110. In this application, the number of shims 1330 is not limited; there may be one or more.

[0064] like 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 on the bottom of the pit 1310 does not correspond to the position of the other columns 1100. Therefore, it is necessary to adjust the verticality and horizontal position of the column 1100. First, adjust the column 1100 to make it vertical. Second, adjust the column 1100 so that its projection position on the bottom of the pit 1310 corresponds to the other columns 1100, that is, the array arrangement.

[0065] like Figure 3As shown in (c), the sag of the column 1100 is adjusted by adjusting system 1320a.

[0066] like Figure 3 As shown in (d), after the verticality and position of the column 1100 are adjusted, the monument-shaped foundation 1300 is made through processes such as mold making, grouting, curing, and demolding.

[0067] Figure 4 This is a schematic diagram of the adjustment system in one embodiment of the prefabricated cooling tower according to the present invention. Figure 5 This is a schematic diagram of the adjustment assembly in the first embodiment of the assembled cooling tower according to the present invention.

[0068] like Figure 3 and Figure 4 As shown, the four adjustment components are arranged around the lower end of the column 1100 to form an adjustment unit. The adjustment system includes multiple layers of the adjustment units spaced apart in the vertical direction.

[0069] For example, the adjustment system 1320a includes eight adjustment components. Figure 4 China will showcase Figure 2 A schematic cross-sectional view taken along the YOZ axis. Adjustment components 1320a1, 1320a2, 1320a3, and 1320a4 are shown within this cross-sectional plane. Additionally, as in... Figure 2 The same four adjustment components are also present when the section is cut along the middle plane of column 1100, which is parallel to the XOZ plane.

[0070] The following example illustrates how to adjust the sag of column 1100 using system 1320a. For example, as... Figure 4 As shown, the column 1100 is in a tilted state, with its center line CC” forming an angle with the vertical line CC'. To make the column 1100 tilt in the direction indicated by arrow P, the lengths of the adjusting components 1320a1 and 1320a4 can be shortened, while the lengths of the adjusting components 1320a2 and 1320a3 can be lengthened.

[0071] Next, we will explain how to adjust the projection position (i.e., horizontal position) of the column 1100 on the bottom surface of the recess 1310 using the adjustment system 1320a. For example, if the center line of the column 1100 is at position EE', to move the center line of the column 1100 from position EE' to position CC', the column 1100 can be moved to the right by increasing the length of the adjustment components 1320a1 and 1320a2 and shortening the length of the adjustment components 1320a3 and 1320a4.

[0072] The aforementioned adjustment system 1320a allows for convenient adjustment of the verticality and position of the column 1100 with high precision.

[0073] Figure 5 Figure 1 is a structural schematic view of an adjusting assembly according to a first embodiment of the assembled cooling tower of the present application.

[0074] As shown in Figure 5 , the adjusting assembly comprises adjusting plates A1 and A2, and an adjusting screw A3. The adjusting 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 adjusting plate A1, and the second threaded section A32 is connected to a threaded hole on the adjusting plate A2. By rotating the adjusting screw A3, the distance between the adjusting plates A1 and A2 can be increased or decreased.

[0075] In other embodiments, the adjusting assembly comprises an adjusting plate A1 and an adjusting screw A3 (not shown), which is threadedly connected to the adjusting plate A1. By rotating the adjusting screw A3, the adjusting assembly can be elongated or shortened.

[0076] In order to facilitate the rotation of the adjusting screw A3, the adjusting screw A3 is further provided with an operating portion A33, which can be a through hole or a hexagonal shape, for example, to facilitate the rotation of the adjusting screw A3 by a tool.

[0077] Figure 6 Figure 2 is a structural schematic view of an adjusting system according to a second embodiment of the assembled cooling tower of the present application. Figure 7 Figure 3 is a structural schematic view of an adjusting assembly according to the second embodiment of the assembled cooling tower of the present application.

[0078] As shown in Figure 6 and Figure 7 , the adjusting system 1320b of the present embodiment comprises adjusting assemblies 1320b1, 1320b2, 1320b3, and 1320b4. The adjusting assembly of the present embodiment comprises first, second, and third wedge-shaped blocks B1, B2, and B3. The upper part of the third wedge-shaped block B3 is wider than the lower part, and 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.

[0079] 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 that is adapted to 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 that is adapted to the second inclined surface B32.

[0080] In use, the third wedge B3 is wedged into the space between the first wedge B1 and the second wedge B2. The length of the adjusting assembly is adjusted by adjusting the depth to which the third wedge B3 is wedged.

[0081] In addition, the number of wedges of the adjusting assembly of the embodiment is not limited, and can be two, four or more, as long as the wedges are connected by the wedge surfaces.

[0082] The working mode of the adjusting system 1320b of the embodiment is similar to that of the adjusting system 1320a, and both are used to adjust the horizontal position and the sag of the column 1100 by increasing or decreasing the length of the adjusting assembly. Details are not repeated here.

[0083] It should be noted that the inner contour of the recess 1310 in the embodiment is a quadrangular prism, and the application does not make special limitations on this. The inner contour of the recess can also be a cylindrical shape, a triangular prism, a pentagonal prism, a hexagonal prism or other shapes.

[0084] After the height position, horizontal position and sag of the column 1100 are adjusted, the molding, grouting, curing and demolding are performed. In the technical solution of the monument type foundation 1300, the adjusting system can support the column 1100, and the structure of the monument type foundation 1300 fills the remaining space of the recess 1310 with concrete. The structure takes advantage of 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 performed without waiting for the concrete to cure to a high strength, which greatly shortens the construction time of the entire cooling tower.

[0085]

Second Embodiment

[0086] 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 connect the cross beam and the column by pre-burying bolts or nuts in the column. In order to prevent the metal connecting piece from rusting and to improve the strength of the connection, concrete is usually poured at the connection between the column and the cross beam. During construction, a formwork is needed to wrap the connection, and the formwork is removed after the concrete is hardened. The construction period is long, which seriously delays the progress of the project.

[0087] In addition, from the perspective of force analysis, the connection structure is connected by 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.

[0088] The application provides a quick and high-strength mortise and tenon connection structure between the column 1100 and the cross beam 1200, which greatly speeds up the construction speed and shortens the overall construction period.

[0089] Figure 8 is a partial enlarged view B in figure Figure 1 . Figure 9 is a partial enlarged view C in figure Figure 1 . Figure 10 is a partial enlarged view D in figure Figure 1 .

[0090] As shown in figure Figure 8 , the mortise and tenon connection structure is applied to the structure schematic diagram of the corner column 1110 and the straight beam 1210. Two straight beams 1210 are arranged at an angle, and the mortise type structure 1140 is formed on the adjacent two side walls of the column 1110. The tenon type structure 1240 is formed at the end of the straight beam 1210, and the tenon type structure 1240 is connected with the mortise type structure 1140.

[0091] In addition, the tenon type structure 1240 and the mortise type structure 1140 can be interchanged, that is, the tenon type structure 1240 can also be formed on the side of the column 1100; correspondingly, the mortise type structure 1140 can also be formed at the end of the cross beam 1200.

[0092] As shown in figure Figure 9 , the mortise and tenon connection structure is applied to the connection structure schematic diagram of the side column 1120 and the straight beam 1210. Three straight beams 1210 are connected with the side column 1120 respectively. The adjacent two straight beams 1210 are arranged at an angle, and the angle is preferably 90°.

[0093] As shown in figure Figure 10 , the mortise and tenon connection structure is applied to the connection structure schematic diagram of the center column 1130 and the straight beam 1210. Four straight beams 1210 are connected with the center column 1130 respectively. The adjacent two straight beams 1210 are arranged at an angle, and the angle is preferably 90°.

[0094] Figure 11 is a structure schematic diagram of a column in an assembled cooling tower according to the utility model.

[0095] As shown in figure Figure 11 , the column 1100 can be, for example, the structure of the corner column 1110 shown in (a) of figure Figure 11 , Figure 11 the structure of the side column 1120 shown in (b) of figure Figure 11 , and the structure of the center column 1130 shown in (c) of figure .

[0096] The following will be described taking the corner column 1110 shown in (a) of figure Figure 12 as an example.

[0097] The corner column 1110 has a first support section 1101 and a second support section 1102 arranged along the up-down direction. The lower end of the second support section 1102 is connected with the upper end of the first support section 1101. And, the horizontal cross-sectional area of the first support section 1101 is greater than that of the second support section 1102. Since the first support section 1101 is located below the second support section 1102, the weight it needs to support is greater than that of the second support section 1102, therefore, setting the cross-sectional area of the first support section 1101 to be greater than that of the second support section 1102 can make the load within the first support section 1101 and the second support section 1102 be distributed reasonably. By reducing the cross-sectional area of the second support section 1102, on one hand, the material consumption can be reduced, the weight can be lightened, and on the other hand, the force acting on the first support section 1101 can be reduced.

[0098] A boss 1103 protruding outwardly is arranged on the lower outer surface of the first support section 1101, and a reinforcing rib 1106 extending upwardly is prefabricated on the boss 1103. The beam 1200 can be connected with the column 1100 through this structure in the case of simple force, for example, only gravity.

[0099] A plurality of mortise structures 1140 are arranged on the first support section 1101 and the second support section 1102, and the mortise structures 1140 are used to realize the connection with the beam 1200.

[0100] Figure 11 For Figure 12 is a partial enlarged view E of the mortise structure.

[0101] As Figure 13 shown, the mortise structure 1140 includes a lateral protrusion 1141 protruding outwardly in the horizontal direction from the side surface of the column 1100. A groove 1142 is arranged on the upper portion of the lateral protrusion 1141. The groove 1142 extends downwardly from the top surface of the lateral protrusion 1141 and does not penetrate the lateral protrusion 1141, and a support surface 1146 is formed at the bottom of the groove 1142. The groove 1142 extends in the horizontal direction from the column 1100 to form a lateral opening. That is, the groove 1142 has two open openings in the upper direction and the lateral direction.

[0102] When viewed outwardly in the horizontal direction from the column 1100, the groove 1142 has an expanding portion 1143 and a contracting portion 1144, and the width (W1) of the expanding portion 1143 is greater than the width (W2) of the contracting portion 1144.

[0103] In addition, when viewed outwardly in the horizontal direction from the column 1100, the width (W3) of the lateral opening of the groove 1143 can be greater than the width (W2) of the contracting portion 1144 to form an expanding portion 1145.

[0104] In addition, a reinforcing pin 1147 extending upward from the supporting surface 1146 is arranged in the middle of the groove 1142. The reinforcing pin 1147 may, for example, be a steel bar pre-arranged in the lateral protrusion 1141 at the lower end.

[0105] Figure 14 The structure diagram of the transverse beam in the fabricated cooling tower according to the present application. Figure 13 The structure diagram of the tenon type.

[0106] As shown in Figure 13 (a), the two ends of the straight beam 1210 in the length direction are respectively provided with a tenon type structure 1240. As shown in Figure 14 (b), the two ends of the curved beam 1230 in the length direction are respectively provided with a tenon type structure 1240.

[0107] As shown in Figure 12 , in some embodiments, the tenon type structure 1240 includes an expansion part 1241 formed at the end thereof, and a necking part 1242 is further arranged between the expansion part 1241 and the body of the transverse beam 1200, and the horizontal width of the necking part 1242 is smaller than the horizontal width of the expansion part 1241. In this embodiment, the horizontal width of the necking part 1242 is smaller than the horizontal width of the body of the transverse beam 1200. In other embodiments, the horizontal width of the body of the transverse beam 1200 can be the same as the horizontal width of the necking part 1242.

[0108] In addition, the tenon type structure 1240 further includes a through hole part 1243 formed at the middle of the width direction close to the necking part 1242 and extending longitudinally, and the position of the through hole part 1243 corresponds to the position of the reinforcing pin 1247. Figure 15

[0109] Figure 15 The structure diagram of the mortise and tenon joint structure in the fabricated cooling tower according to the present application.

[0110] As shown in Figure 15 , the column 1100 and the transverse beam 1200 are connected through the mortise and tenon joint structure to realize fast and high-strength connection. Wherein, the tenon type structure 1240 at the end of the transverse beam 1200 is arranged in the groove 1142 on the lateral protrusion 1141 of the upper side of the column 1100. The outer contour of the tenon type structure 1240 is matched with the groove contour shape of the mortise type structure 1140, and there is a gap between the tenon type structure 1240 and the mortise type structure 1140 to form a first grouting space G1. Preferably, the blocking material D1, D2 blocking the vertical gap at the edge of the mortise type structure 1140 is arranged in the horizontal direction away from the edge of the first grouting space G1.

[0111] In addition, the reinforcing pin 1147 is arranged in the middle of the groove 1142. Figure 16 ​As can be seen, the width of the expansion part 1241 of the tenon-shaped structure 1240 in the horizontal direction is greater than the width of the contraction part 1144 of the mortise-shaped structure 1140 in the horizontal direction.

[0112] The reinforcing pin 1147 on the mortise-shaped structure 1140 is inserted into the through hole part 1243 of the tenon-shaped structure 1240, and the reinforcing pin 1147 and the through hole part 1243 form a second grouting space G2.

[0113] First, after the tenon-shaped structure 1240 is inserted into the mortise-shaped structure 1140, only the gap extending vertically away from the edge of the mortise-shaped structure in the first grouting space G1 needs to be blocked by the blocking material D1 and D2 before grouting, and the grouting can be performed, the blocking material D1 and D2 can be foam, wood board and the like, which can be cured in the mortise and tenon connection structure, thereby saving the process of molding and demolding and saving the operation time. The second grouting space G2 can be directly filled with concrete and the like, and there is no need to make a mold.

[0114] Secondly, the first grouting space G1 and the second grouting space G2 only need a small amount of concrete to be filled, and in construction, a flexible grouting method can be used to improve the grouting speed. The curing time of the small amount of concrete is also less.

[0115] Thirdly, the mortise and tenon connection structure can quickly form a stable connection between the cross beam 1200 and the column 1100, and subsequent construction can be carried out without waiting for the grouted concrete to completely cure, thereby saving the overall construction time of the cooling tower.

[0116] Therefore, the mortise and tenon connection structure can greatly improve the construction efficiency of the cooling tower, save the construction time, improve the overall strength of the cooling tower, and has a wide application prospect.

[0117] Figure 16 FIG. 2 is a schematic view of a mortise and tenon connection structure according to a second embodiment of the assembled cooling tower of the present application. Figure 17 In the figure, the width of the body of the cross beam 1200 in the horizontal direction is the same as the width of the necked part 1242 in the horizontal direction.

[0118] Figure 18 FIG. 3 is a schematic view of a mortise and tenon connection structure according to a third embodiment of the assembled cooling tower of the present application, which is a cross-sectional view along the horizontal direction. Figure 17 FIG. 4 is a longitudinal sectional view of the mortise and tenon connection structure according to the third embodiment of the assembled cooling tower of the present application.

[0119] As can be seen, Figure 18As shown, the mortise structure 1140 has a through hole 1148 which is horizontally through the lateral protrusion 1141. The tenon structure 1240 has a through hole part 1243 which corresponds to the through hole 1148 and extends horizontally through the tenon structure 1240.

[0120] 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 part 1243, and the reinforcing pin 1147 is placed in the through hole 1148 and the through hole part 1243, and then grouting is performed.

[0121] In this embodiment, after grouting is completed, the two ends of the reinforcing pin 1147 are solidified with the lateral protrusion 1141, and the connection strength is higher than that of the longitudinal arrangement.

[0122] As shown, Figure 19 In this embodiment, the support surface 1146 is inclined, and gradually rises from the direction close to the column 1100 to the direction away from the column 1100. The bottom surface of the tenon structure 1240 has a structure matched with the support surface 1146. The inclined support surface 1146 can also play a role in strengthening the connection strength of the mortise and tenon connection structure.

[0123] Figure 20 It is a longitudinal sectional view of the mortise and tenon connection structure of the fourth embodiment of the assembled cooling tower according to the present application. In this embodiment, the support surface 1146 can also be a horizontal surface.

[0124] Figure 20 It is a structure schematic view of a pin shaft of one embodiment of the assembled cooling tower according to the present application.

[0125] As shown, ​ The reinforcing pin 1147 has a first end and a second end arranged oppositely, and a support part 11471 is fixedly arranged at each of the first end and the second end for supporting the reinforcing pin 1147. When the reinforcing pin 1147 is placed into the through hole part 1243 and the through hole 1148, the support part 11471 can support the reinforcing pin 1147, so that the reinforcing pin 1147 is kept at the center position of the through hole part 1243. The number of the support part 1147 is not particularly limited, as long as it can support the reinforcing pin 1147. The support part 11471 can be, for example, four cylindrical structures evenly arranged around the reinforcing pin 1147 and extending in the radial direction, or a ring-shaped structure integrally connected with the reinforcing pin 1147.

[0126] The assembly type cooling tower structure of the preferred embodiments of the present application is described in detail above, but various modifications, changes, combinations, etc. can be made by those skilled in the art on the basis of the foregoing, and these modifications, changes, combinations all fall within the protection scope of the claims of the present application.
