Description

Prefabricated cooling tower and its construction technology Technical Field

[0001] The present invention relates to the technical field of cooling equipment, and in particular to an assembled cooling tower and a construction process thereof. Background Art

[0002] Cooling towers are used to cool hot water in industrial production. Some existing cooling towers have a main body consisting of, from bottom to top, a water collection section, an air intake section, a heat exchange section, and a spray section. The upper portion of the main body also houses an exhaust section, which includes an air duct and an induced draft fan housed within it.

[0003] When the induced draft fan rotates, the external cold air enters the main body from the air inlet part, passes through the heat exchange part, spray part, mist elimination part and air mixing part in sequence, and is finally discharged from the exhaust part.

[0004] Hot water is sprayed out from the nozzle of the spray part, exchanges heat with the cold air in the heat exchange part, and falls to the water collection part for recycling.

[0005] Traditional cooling tower frames are manufactured using a wet concrete process. This requires concrete to cure to achieve sufficient strength, and multi-layered structures require the lower layers to cure before the upper layers can be constructed, leading to significant manufacturing time. Furthermore, some existing cooling towers utilize steel frames, which can be noisy and vibrating, prone to rust, and have a short service life.

[0006] In order to solve the above technical problems, although engineers and technicians in this field have made many improvements to the cooling tower, the results are not satisfactory or the cost is high. Summary of the Invention

DETAILED DESCRIPTION

[0085] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0086] [First embodiment]

[0087] FIG1 is a structural diagram of a frame of an assembled cooling tower according to the present invention.

[0088] As shown in Figure 1, the assembled cooling tower frame 1000 includes a plurality of columns 1100 arranged at intervals. The cooling tower frame in Figure 1 has a quadrangular prism structure, and each of the four corners of the assembled cooling tower frame 1000 has a corner column 1110, including corner column 1110a, corner column 1110b, corner column 1110c, and corner column 1110d.

[0089] It should be noted that the cooling tower frame 1000 in Figure 1 is a quadrangular prism structure, but the present application is not limited to this. The cooling tower frame 1000 can also be a triangular prism, a pentagonal prism, a hexagonal prism, or a heptagonal prism... Depending on the external structure of the cooling tower, there are correspondingly different numbers of corner columns 1110.

[0090] Referring to the coordinate system in Figure 1 , along the X-direction, three side posts 1120a, 1120b, and 1120c are located between corner posts 1110a and 1110b. Corner post 1110a, side post 1120a, side post 1120b, side post 1120c, and corner post 1110b are arranged sequentially and at equal intervals. Along the Y-direction, a side post 1120d is located between corner posts 1110a and 1110b. Corner post 1110a, side post 1120d, and corner post 1110b are arranged sequentially and at equal intervals.

[0091] It should be noted that this application does not limit the number of the above-mentioned side columns 1120. Those skilled in the art may provide different numbers of side columns 1120 according to the length and width of the cooling tower. The spacing between adjacent corner columns 1110 and side columns 1120, and the spacing between two adjacent side columns 1120, may also be unequal.

[0092] In addition, in this embodiment, the columns on both sides of the cooling tower in the length direction (along the X axis) are arranged symmetrically, and the columns on both sides in the width direction (along the Y axis) are also arranged symmetrically, but they can also be arranged asymmetrically.

[0093] Three central columns 1130 are located in the center 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.

[0094] From a top view, the pillars 1100 are arranged in an array, but the present application is not limited thereto.

[0095] In some existing technologies, the column 1100 is connected to the foundation through bolts and nuts, and then the molding, grouting, curing, and demolding processes are carried out to form the foundation of the column. In addition, subsequent construction can only be carried out after the concrete is completely cured, which results in a long construction period.

[0096] Figure 2 is a partial enlarged view A in Figure 1, showing the appearance of the monument-shaped foundation where the column 1100 is connected to the foundation. Figure 3 is a schematic diagram of the manufacturing process of the monument-shaped foundation of an embodiment of the assembled cooling tower according to the present invention.

[0097] As shown in (a) of Figure 3 , a pit 1310 for installing the column 1100 is first prefabricated in the foundation. In order to adjust the verticality, horizontal position and height position of the column 1100. The applicant of the present invention has designed an adjustment system. The adjustment system may, for example, include pads 1330 stacked at the bottom of the pit, and the height of the pit bottom is adjusted by adjusting the number of pads 1330, thereby adjusting the bottom surfaces of multiple columns 1100 to the same height position. In addition, the bottom height of each column 110 can also be adjusted by machining pads 1330 of a specific thickness. In this application, there is no limitation on the number of pads 1330, and it can be one or more.

[0098] As shown in (b) of Figure 3, 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 does not correspond to the positions of other columns 1100. Therefore, it is necessary to adjust the verticality and horizontal position of the column 1100. First, adjust the column 1100 to be in a vertical state; second, adjust the column 1100 so that its projection position at the bottom of the pit 1310 corresponds to the other columns 1100, that is, arrange it in an array.

[0099] As shown in FIG3( c ), the sag of the column 1100 is adjusted by adjusting the system 1320 a .

[0100] As shown in FIG3( d ), after the verticality and position of the column 1100 are adjusted, the monument-shaped foundation 1300 is manufactured through processes such as molding, grouting, curing, and demolding.

[0101] Figure 4 is a schematic diagram of the structure of an adjustment system in an embodiment of an assembled cooling tower according to the present invention. Figure 5 is a schematic diagram of the structure of an adjustment assembly in a first embodiment of an assembled cooling tower according to the present invention.

[0102] As shown in Figures 3 and 4, four adjustment assemblies are arranged around the lower end of the column 1100 to form a set of adjustment units. The adjustment system includes multiple layers of adjustment units that are spaced apart in the vertical direction.

[0103] For example, adjustment system 1320a includes eight adjustment components. FIG4 shows a schematic cross-sectional view of FIG2 taken along the YOZ plane. Within this cross-sectional plane, adjustment components 1320a1, 1320a2, 1320a3, and 1320a4 are shown. Furthermore, as shown in FIG2 , a cross-sectional view taken along a plane parallel to the XOZ plane and located in the middle of column 1100 also shows the same four adjustment components.

[0104] The following example illustrates how to adjust the sag of column 1100 using adjustment system 1320a. For example, as shown in Figure 4 , column 1100 is tilted, with its centerline CC" forming an angle with plumb line CC'. To deflect column 1100 in the direction indicated by arrow P, this can be achieved by shortening adjustment components 1320a1 and 1320a4 and lengthening adjustment components 1320a2 and 1320a3.

[0105] Next, we will explain how to use adjustment system 1320a to adjust the projected position (i.e., horizontal position) of column 1100 on the bottom surface of pit 1310. For example, if the centerline of column 1100 is at position EE', to move the centerline of column 1100 from position EE' to position CC', column 1100 can be shifted rightward by increasing the lengths of adjustment components 1320a1 and 1320a2 and shortening the lengths of adjustment components 1320a3 and 1320a4.

[0106] The adjustment system 1320a can be used to conveniently adjust the verticality and position of the column 1100 with high precision.

[0107] FIG5 is a schematic structural diagram of an adjustment assembly in a first embodiment of an assembled cooling tower according to the present invention.

[0108] As shown in Figure 5, the adjustment assembly includes adjustment plates A1 and A2, and an adjustment screw A3. Adjustment screw A3 includes a first threaded segment A31, a second threaded segment A32, and an operating portion A33. The first and second threaded segments A31 and A32 have opposite threads. The first threaded segment A31 connects to a threaded hole in adjustment plate A1, while the second threaded segment A32 connects to a threaded hole in adjustment plate A2. Turning adjustment screw A3 increases or decreases the distance between adjustment plates A1 and A2.

[0109] In other embodiments, the adjustment assembly includes an adjustment plate A1 and an adjustment screw A3 (not shown), and the adjustment screw A3 is threadedly connected to the adjustment plate A1. The adjustment assembly can be extended or shortened by rotating the adjustment screw A3.

[0110] In order to facilitate the rotation of the adjustment screw A3, an operating portion A33 is further provided on the adjustment screw A3. The operating portion A33 can be, for example, a through hole passing through the adjustment screw A3, or can be hexagonal, so as to facilitate the rotation of the adjustment screw A3 by a tool.

[0111] Figure 6 is a schematic diagram of the structure of the adjustment system of the second embodiment of the assembled cooling tower according to the present invention. Figure 7 is a schematic diagram of the structure of the adjustment assembly of the second embodiment of the assembled cooling tower according to the present invention.

[0112] As shown in Figures 6 and 7, the adjustment system 1320b of this embodiment includes adjustment components 1320b1, 1320b2, 1320b3, and 1320b4. The adjustment components of this embodiment include a first wedge block B1, a second wedge block B2, and a third wedge block B3. The upper width of the third wedge block B3 is greater than its lower width. A first inclined surface B31 is formed on one side of the third wedge block B3, and a second inclined surface B32 is formed on the other side of the third wedge block B3.

[0113] The first wedge block B1 has a vertical plane B21 on one side and a third slope B11 on the other side, with a slope matching the first slope B31. The second wedge block B2 has a vertical plane B22 on one side and a fourth slope B21 on the other side, with a slope matching the second slope B32.

[0114] When in use, the third wedge block B3 is wedged into the space between the first wedge block B1 and the second wedge block B2. The length of the adjustment assembly can be adjusted by adjusting the wedging depth of the third wedge block B3.

[0115] In addition, the number of wedge blocks in the adjustment assembly of this embodiment is not limited and can be two, or four or more, as long as some adjacent wedge blocks are connected by wedge surfaces.

[0116] The adjustment system 1320b of this embodiment works in a similar manner to the adjustment system 1320a, both of which adjust the horizontal position and verticality of the column 1100 by increasing or decreasing the length of the adjustment component, which will not be repeated here.

[0117] It should be added that, in this embodiment, the inner contour of the pit 1310 is a quadrangular prism, to which this application does not impose any special limitation, and the inner contour of the pit may also be cylindrical, triangular, pentagonal, hexagonal or other shapes.

[0118] After adjusting the height, horizontal position, and verticality of the columns 1100, mold making, grouting, curing, and demolding are then performed. In the technical solution of the monument-shaped foundation 1300 of this application, the adjustment system can provide support for the columns 1100. In addition, the structure of the monument-shaped foundation 1300 uses concrete to fill the remaining space in the pit 1310. This structure utilizes the characteristic of concrete that its "compressive" strength is greater than its "tensile" strength. Based on these two points, subsequent construction can be carried out without waiting for the concrete to cure to a high strength, significantly shortening the overall construction time of the cooling tower.

[0119] [Second embodiment]

[0120] In some existing prefabricated cooling towers, the beam-column connection structure features a protrusion (commonly known as a "corbel") on the column below the connection. This protrusion supports the beam, and bolts or nuts are embedded in the column to connect the beam and column. To prevent rusting of the metal connectors and to enhance the strength of the connection, concrete is often poured at the column-beam junction. During construction, formwork is fabricated to wrap around the junction, grouting, and removal of the formwork after the concrete has hardened. This results in a lengthy construction period, significantly slowing down the project's progress.

[0121] Moreover, from the perspective of force, the connection structure is achieved through metal parts embedded in the columns and beams. Due to the low tensile strength of concrete, the strength of the above connection method is relatively weak.

[0122] Through continuous research and experimentation, the inventors of this application have revolutionized the above technical problems and proposed a fast and high-strength mortise and tenon connection structure between the column 1100 and the beam 1200, which greatly speeds up the construction process and shortens the overall construction period.

[0123] Figure 8 is a partial enlarged view B in Figure 1. Figure 9 is a partial enlarged view C in Figure 1. Figure 10 is a partial enlarged view D in Figure 1.

[0124] As shown in Figure 8, the mortise and tenon connection structure is applied to a corner column 1110 and a straight beam 1210. Two straight beams 1210 are arranged at an angle, and mortise and tenon structures 1140 are formed on two adjacent side walls of the column 1110. Tenon and tenon structures 1240 are formed at the ends of the straight beams 1210, connecting the tenon and tenon structures 1140.

[0125] 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.

[0126] Figure 9 shows a schematic diagram of the mortise and tenon connection structure used to connect side columns 1120 and straight beams 1210. Three straight beams 1210 are connected to side columns 1120, respectively. Adjacent straight beams 1210 are spaced at an angle, preferably 90°.

[0127] As shown in Figure 10, the mortise and tenon connection structure is applied to the connection structure of the central column 1130 and the straight beam 1210. Among them, four straight beams 1210 are connected to the central column 1130 respectively. The adjacent straight beams 1210 are arranged at an angle, preferably, the angle is 90 degrees.

[0128] FIG11 is a schematic structural diagram of a column in an assembled cooling tower according to the present invention.

[0129] As shown in FIG11 , the column 1100 may be, for example, a structure of a corner column 1110 shown in FIG11( a ), a side column 1120 shown in FIG11( b ), and a center column 1130 shown in FIG11( c ).

[0130] The following description will be made using the corner column 1110 shown in FIG. 11( a ) as an example.

[0131] This corner post 1110 comprises a first support segment 1101 and a second support segment 1102 arranged in a vertical direction. 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. Because the first support segment 1101 is located below the second support segment 1102 and needs to support a greater weight than the second support segment 1102, setting the cross-sectional area of ​​the first support segment 1101 larger than that of the second support segment 1102 allows for proper load distribution within the first and second support segments 1101, 1102. Reducing the cross-sectional area of ​​the second support segment 1102 not only reduces material consumption and weight, but also reduces the force exerted on the first support segment 1101.

[0132] The lower outer surface of the first support section 1101 is provided with an outwardly protruding boss 1103, on which upwardly extending reinforcing ribs 1106 are prefabricated. In simple force conditions, such as when only gravity is applied, the beam 1200 can be connected to the column 1100 through this structure.

[0133] A plurality of mortise-shaped structures 1140 are provided on the first supporting segment 1101 and the second supporting segment 1102 . The mortise-shaped structures 1140 are used to achieve connection with the crossbeam 1200 .

[0134] FIG12 is a partial enlarged view E in FIG11, ie, a schematic diagram of the mortise-shaped structure.

[0135] As shown in FIG12 , the mortise-shaped structure 1140 includes a lateral protrusion 1141 extending horizontally outward from the side of the column 1100. A recess 1142 is provided above the lateral protrusion 1141. The recess 1142 extends downward from the top surface of the lateral protrusion 1141 without passing through the lateral protrusion 1141. A support surface 1146 is formed at the bottom of the recess 1142. The recess 1142 extends horizontally from the column 1100 to form a lateral opening. Specifically, the recess 1142 has two openings: one at the top and one at the side.

[0136] Looking outward from the pillar 1100 along the horizontal direction, the groove 1142 has an inwardly expanding portion 1143 and a contracting portion 1144 . The width ( W1 ) of the inwardly expanding portion 1143 is greater than the width ( W2 ) of the contracting portion 1144 .

[0137] Furthermore, when viewed horizontally from the pillar 1100 , the width ( W3 ) of the lateral opening of the groove 1143 may be greater than the width ( W2 ) of the contraction portion 1144 to form a flared portion 1145 .

[0138] In addition, a reinforcement pin 1147 extending upward from the support surface 1146 is provided in the middle of the groove 1142. The reinforcement pin 1147 can be, for example, a steel bar with its lower end prefabricated in the lateral protrusion 1141.

[0139] Figure 13 is a schematic diagram of the structure of the crossbeam in the assembled cooling tower according to the present invention. Figure 14 is a schematic diagram of the tenon-type structure.

[0140] As shown in FIG13(a), a tenon structure 1240 is provided at each end of the lengthwise direction of the straight beam 1210. As shown in FIG13(b), a tenon structure 1240 is provided at each end of the lengthwise direction of the curved beam 1230.

[0141] As shown in FIG14 , in some embodiments, the tenon-shaped structure 1240 includes an expanded portion 1241 formed at its end. A constricted portion 1242 is provided between the expanded portion 1241 and the main body of the crossbeam 1200. The horizontal width of the constricted portion 1242 is smaller than the horizontal width of the expanded portion 1241. In this embodiment, the horizontal width of the constricted portion 1242 is smaller than the horizontal width of the main body of the crossbeam 1200. In other embodiments, the horizontal width of the main body of the crossbeam 1200 may be the same as the horizontal width of the constricted portion 1242.

[0142] In addition, the tenon-type structure 1240 further includes a through hole portion 1243 formed in the middle of the width direction near the neck portion 1242 and extending longitudinally. The position of the through hole portion 1243 corresponds to the position of the reinforcing pin 1247 in FIG. 12 .

[0143] FIG15 is a schematic diagram of the mortise and tenon connection structure of the first embodiment of the assembled cooling tower according to the present invention.

[0144] As shown in Figure 15, the mortise and tenon connection structure achieves a fast and high-strength connection between the column 1100 and the beam 1200. The tenon structure 1240 at the end of the beam 1200 is inserted into the groove 1142 on the lateral protrusion 1141 on the column 1100. The outer contour of the tenon structure 1240 matches the contour of the groove of the mortise structure 1140, and a gap is formed 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 edges of the first grouting space G1 in the horizontal direction away from the mortise structure 1140 to seal the vertical gap at the edges.

[0145] In addition, it can be seen from FIG. 15 that the horizontal width of the expansion portion 1241 of the tenon-shaped structure 1240 is greater than the horizontal width of the contraction portion 1144 of the mortise-shaped structure 1140 .

[0146] The reinforcing pin 1147 on the mortise structure 1140 is inserted into the through hole portion 1243 of the tenon structure 1240 , forming a second grouting space G2 between the reinforcing pin 1147 and the through hole portion 1243 .

[0147] First, after the tenon structure 1240 is placed within the mortise structure 1140, before grouting, the grouting operation can be performed by simply sealing the gap extending vertically from the edge of the first grouting space G1 in the horizontal direction away from the mortise structure using sealing materials D1 and D2. The 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 mold making and demolding process and saving work time. The second grouting space G2 can be directly poured with a filling material such as concrete without the need for mold making.

[0148] Secondly, the first grouting space G1 and the second grouting space G2 only need a small amount of concrete to be filled, and during construction, a flexible grouting method can be adopted to increase the grouting speed. The small amount of concrete also requires less curing time.

[0149] Again, the above-mentioned mortise and tenon connection structure can quickly form a stable connection between the beam 1200 and the column 1100, and subsequent construction can be carried out without having to wait for the poured concrete to completely solidify, thereby saving the overall construction time of the cooling tower.

[0150] Therefore, the above-mentioned mortise and tenon connection structure can greatly improve the construction efficiency of the cooling tower, save construction time, and improve the overall strength of the cooling tower, and has broad prospects for promotion and application.

[0151] Figure 16 is a schematic diagram of the mortise and tenon connection structure of the second embodiment of the assembled cooling tower according to the present invention. In Figure 16 , the horizontal width of the main body of the crossbeam 1200 is the same as the horizontal width of the neck portion 1242 .

[0152] Figure 17 is a schematic diagram of a mortise and tenon connection structure of a third embodiment of an assembled cooling tower according to the present invention, which is a horizontal cross-section. Figure 18 is a longitudinal cross-section of a mortise and tenon connection structure of a third embodiment of an assembled cooling tower according to the present invention.

[0153] As shown in FIG17 , in the mortise and tenon connection structure of this embodiment, the mortise structure 1140 has a through hole 1148 that horizontally passes through the lateral protrusion 1141. The tenon structure 1240 has a through hole portion 1243 corresponding to the through hole 1148, which extends horizontally and passes through the tenon structure 1240.

[0154] After the tenon structure 1240 is installed in the groove 1142 of the mortise structure 1140, the through hole 1148 is aligned with the through hole portion 1243, and the reinforcing pin 1147 is placed in the through hole 1148 and the through hole portion 1243 and then grouting is performed.

[0155] In this embodiment, after the grouting is completed, both ends of the reinforcing pin 1147 are solidified together with the lateral protrusion 1141, which has a higher connection strength than the longitudinal arrangement.

[0156] As shown in FIG18 , in this embodiment, support surface 1146 is inclined and gradually rises from closer to column 1100 to farther away from column 1100. The bottom surface of tenon-shaped structure 1240 has a structure that matches support surface 1146. The inclined support surface 1146 also serves to strengthen the connection strength of the mortise and tenon joint structure.

[0157] Figure 19 is a longitudinal cross-sectional view of the mortise and tenon connection structure of the fourth embodiment of the assembled cooling tower according to the present invention. In this embodiment, the support surface 1146 can also be a horizontal surface.

[0158] FIG20 is a schematic structural diagram of a pin shaft in an embodiment of an assembled cooling tower according to the present invention.

[0159] As shown in Figure 20, the reinforcing pin 1147 has a first end and a second end that are arranged 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. After the reinforcing pin 1147 is placed into the through-hole portion 1243 and the through-hole 1148, the support portion 11471 can support the reinforcing pin 1147, so that the reinforcing pin 1147 remains at the center position of the through-hole portion 1243. There is no particular limitation on the number of the support portions 1147, as long as they can support the reinforcing pin 1147. The support portion 11471 can, for example, be a plurality of cylinders that are evenly distributed around the reinforcing pin 1147 and extend in the radial direction, or a ring-shaped structure that is connected to the reinforcing pin 1147 as a whole.

[0160] FIG21 is a perspective view of a wall panel fixing structure 1400 of an assembled cooling tower according to the present invention.

[0161] As shown in FIG21 , a cooling tower wall panel fixing structure 1400 includes an inner bracket 1410 positioned outside a column 1100 of a cooling tower 1000; an outer bracket 1420 snap-fitted to the inner bracket 1410; and 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 that passes through the outer bracket 1420 and connects to the column. The fastener 1450 enables the outer bracket 1420 and the inner bracket 1410 to clamp the edge of the wall panel 1430.

[0162] The cooling tower wall panel fixing structure 1400 has unique advantages when used in the construction process of an assembled cooling tower. After the internal construction of the cooling tower is completed, the wall panel is fixed in at least one direction through the slot 1460 between the outer bracket 1420 and the inner bracket 1410. The construction is convenient and fast, which greatly improves the construction speed of the cooling tower.

[0163] The slots 1460 are symmetrically formed on both sides of the inner bracket 1410 and the outer bracket 1420 in the width direction. This provides support for the wall panels 1430 on both sides, reducing manufacturing costs. However, in the corners of the cooling tower, the slots 1460 can also be formed on only one side of the wall panel fixing structure 1400 in the width direction.

[0164] Preferably, the wall panel fixing structure 1400 further includes a support frame 1440 fixedly connected to the column 1100 and supported on the underside of the wall panel 1430. The support frame 1440 can be made of a profile such as angle iron or channel steel. The ends of the support frame 1440 are respectively fixedly connected to the columns 1100 on either side thereof. The ends of the support frame 1440 can also be respectively connected to the inner brackets 1410 on either side thereof.

[0165] FIG22 is a structural diagram of the inner bracket 1410 .

[0166] As shown in Figure 22, the inner bracket 1410 has an inner bottom plate 1411 and a first and a second guide plate 1412 and 1413 connected to 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 first guide plate 1412, the second guide plate 1413 and the inner bottom plate 1411 have the same extension direction; the first guide plate 1412 and the second guide plate 1413 are arranged at intervals; the first guide plate 1412 is spaced apart from one side edge of the inner bottom plate 1411 in the width direction, and the second guide plate 1413 is spaced apart from the other side edge of the inner bottom plate 1411 in the width direction.

[0167] In the inner bracket 1410 , the inner bottom plate 1411 can be connected to the column 1100 by screws, etc. The first guide plate 1412 and the second guide plate 1413 are spaced from the edges of both sides of the inner bottom plate 1411 in the width direction, thereby providing space for forming the slot 1460 .

[0168] FIG23 is a structural diagram of the outer bracket 1420 .

[0169] The outer bracket 1420 has an outer bottom plate 1421 and a third and fourth guide plates 1422 and 1423 connected to the outer bottom plate 1421; the third guide plate 1422 and the fourth guide plate 1423 are both perpendicular to the outer bottom plate 1421, and the third guide plate 1422, the fourth guide plate 1423 and the outer bottom plate 1421 have the same extension direction; the third guide plate 1422 and the fourth guide plate 1423 are arranged at intervals; the third guide plate 1422 is spaced apart from one side edge of the outer bottom plate 1421 in the width direction, and the fourth guide plate 1423 is spaced apart from the other side edge of the outer bottom plate 1421 in the width direction.

[0170] When the outer bracket 1420 and the inner bracket 1410 are buckled together, 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.

[0171] The connection between the first and second guide plates 1412 , 1413 and the third and fourth guide plates 1422 , 1423 can serve as a guide when the outer bracket 1420 and the inner bracket 1410 are connected, and provide a stable support for the wall panel 1430 .

[0172] FIG24 is a schematic diagram of the top view of the wall panel fixing structure 1400 .

[0173] The surface of the column 1100 facing the outside of the cooling tower is prefabricated with an embedded part 1150, and the fastener 1450 is connected to the embedded part 1150. The embedded part 1150 is a nut or a bolt, which is pre-buried inside the column 1100 when the column 1100 is prefabricated.

[0174] In the assembled cooling tower 1000, the wall panel fixing structure 1400 can quickly and firmly install the wall panel 1430 on the cooling tower, greatly improving the construction speed of the cooling tower.

[0175] [Third embodiment]

[0176] Figure 25 is a schematic diagram of the structure of an assembled cooling tower according to the third embodiment of the present invention. Figure 26 is a partial enlarged view of point E in Figure 25.

[0177] As shown in FIG. 25 and FIG. 26 , in order to further increase the construction speed of the prefabricated cooling tower, this embodiment provides a prefabricated cooling tower with a floating foundation.

[0178] Specifically, a base 2110 is provided at the bottom end of the column 2100, and the base 2110 has a larger horizontal cross-sectional area relative to the column body of the column 2100. Before construction, a horizontal ground is first prefabricated at the installation location of the prefabricated cooling tower 2000, or a local horizontal installation position is set at the installation location of the column 2100. The column 2100 with the base 2110 is placed at the above-mentioned installation position and each column 2100 is connected to the frame of the prefabricated cooling tower 2000 using a mortise and tenon connection structure. The construction speed of the above-mentioned prefabricated cooling tower with a floating foundation is greatly improved, and because the frame of the prefabricated cooling tower is connected to the ground in a floating manner, it has a higher seismic resistance level.

[0179] In addition, in the reconstruction project of the old tower, the above-mentioned prefabricated cooling tower 2000 can be assembled in a position near the original cooling tower, and the original cooling tower can be kept in operation until the construction of the prefabricated cooling tower 2000 is completed. The original cooling tower is then dismantled and the newly built prefabricated cooling tower 2000 is moved to the position of the original cooling tower by hoisting or other methods, thereby minimizing the equipment downtime caused by the cooling tower reconstruction and significantly reducing the impact of construction on normal production.

[0180] The base 2110 can be prefabricated integrally with the column 2100, or it can be assembled and connected to the lower end of the column 2100. As shown in Figure 27, a first flange 2120 is prefabricated at the upper end of the base 2110, and a second flange 2130 is prefabricated at the lower end of the column 2100. During installation, the column 2100 and the base 2110 are connected integrally via a fastening assembly 2140. This structure facilitates the manufacture and transportation of the column 2100.

[0181] It should be noted that a mortise-and-tenon structure 1140 or a tenon-and-short structure 1240 can be preset on the column 2100 of this embodiment, which is beneficial to improving the overall construction speed of the assembled cooling tower.

[0182] Figure 28 is a schematic structural diagram of a prefabricated cooling tower column with a split structure according to the present invention. Figure 29 is an enlarged view of a portion F in Figure 28 .

[0183] As shown in Figures 28 and 29, column 2100 includes a first support segment 2101 and a second support segment 2102 arranged in a vertical direction. A first connecting portion 2103 is provided at the upper end of the first support segment 2101, and a second connecting portion 2104 connected to the first connecting portion 2103 is provided at the lower end of the second support segment 2102. The first connecting portion 2103 and the second connecting portion 2104 may be flanges, for example, so that the first connecting portion 2103 and the second connecting portion 2104 can be detachably connected via fastening elements 2105 such as bolts. Alternatively, column 2100 may include more than two support segments, with the detachable connection structure provided between some of the support segments. Further preferably, the horizontal cross-sectional area of ​​each support segment may gradually decrease from bottom to top.

[0184] In addition, in the present invention, a mortise and tenon structure or a tenon and tenon structure may be provided in the first support segment 2101 and / or the second support segment 2102 to achieve connection with the crossbeam, thereby assembling to form the frame structure of the assembled cooling tower 2000 .

[0185] The assembled cooling tower column 2100 with a split structure of the present invention is easy to manufacture and transport, and is easy to standardize, thereby accelerating the construction speed of the assembled cooling tower 2000.

[0186] The above is a detailed description of the assembled cooling tower structure and its construction process of the preferred embodiment of the present invention, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes, and combinations all fall within the scope of protection of the claims of this application.
