  The outer column member 11b and each support member 13 are rotatably connected by a second connecting member 41. In the present embodiment, the positional relationship between the outer column member 11b and each support member 13 is also changed in the state at the time of transport to the construction site and at the time of assembly at the construction site, similarly to the positional relationship between the column member 11 and the beam member 12. Is done. That is, the first assembly unit 20A rotates the support member 13 with respect to the outer column member 11b, so that the first assembly unit 20A can be transported from a factory or the like to a construction site in a more compact state than the completed state of the cooling tower 1. It is configured. In the state when the cooling tower 1 is completely assembled, the support member 13 forms a third angle with respect to the outer column member 11b, and the support member 13 moves to the outer column member 11b when transported to the construction site. On the other hand, a fourth angle smaller than the third angle is formed. In the following description, like the position of the beam member 12, the position of the support member 13 with respect to the outer column member 11 b at the time of conveyance to the construction site is referred to as a “folded position”, and the outer column member at the completion of the assembly of the cooling tower 1. The position of the support member 13 with respect to 11b is referred to as a “deployment position”.

  FIG. 6 is an enlarged view of a portion V in FIG. 3 in which the connection portion between the outer column member 11b and the support member 13 is enlarged. In FIG. 6, the support member 13 in the unfolded position with respect to the outer column member 11b is indicated by a solid line, and the support member 13 in the folded position is indicated by a two-dot chain line.

  The configuration of the connection portion between the outer column member 11b and the support member 13 is substantially the same as the above-described configuration of the connection portion between the connection portion 22 and the beam member 12 in the outer column member 11b. That is, as shown in FIG. 6, the second connecting member 41 that connects the outer column member 11b and the support member 13 includes a bolt 41a, a nut (not shown), and a sleeve (not shown). The outer column member 11b and the support member 13 partially overlap each other when viewed from the front. Bolts 41a of the second connecting member 41 and the through holes (not shown) formed in the outer column member 11b and the support member 13 respectively. The sleeve is inserted, and then a nut is screwed onto the bolt. Thus, the outer column member 11b and the support member 13 are rotatably connected around the rotation axis C3 of the bolt 41a.

  In addition to the through hole for the second connecting member 41, through holes 42 and 13 a are formed in the outer column member 11 b and the support member 13, respectively. The centers of the through holes 42 and 13a coincide with each other when the support member 13 is in the deployed position. When the centers of the through holes 42 and 13a coincide with each other, a bolt as the second fixing member 43 (see FIG. 3 and omitted in FIG. 6) is inserted in the same manner as the first fixing members 23 and 33 described above. Thus, the support member 13 is fixed to the outer column member 11b.

  Next, the second assembly unit 50 will be described with reference to FIG. FIG. 7 is a front view of the second assembly unit 50. The second assembly unit 50 includes one central column member 11 a, two beam members 12, and four wire members 16.

  The central column member 11 a and each beam member 12 are connected to each other by a first connecting member 51 so as to be rotatable. More specifically, the central column member 11a is provided with two connection portions 52 that protrude in opposite directions. Each connection portion 52 has a substantially plate shape, and one end portion of each beam member 12 is rotatably connected to each connection portion 52 by a first connection member 51. The other end of each beam member 12 is connected to each connection portion 36 of the left and right first assembly units 20A when the cooling tower 1 is constructed and assembled.

  Similarly to the first assembly unit 20A, in the second assembly unit 50, the beam member 12 is rotated with respect to the column member (center side column member 11a), so that the state of the cooling tower 1 at the time when the assembly is completed. It is compact so that it can be transported from the factory to the construction site. Specifically, the beam member 12 is connected to the first coupling so as to rotate between a deployed position orthogonal to the central column member 11a and a folded position substantially parallel to the central column member 11a. The member 51 is connected to the central column member 11a. In FIG. 7, the beam member 12 in the folded position is indicated by a two-dot chain line.

  The configuration of the connection portion between the central column member 11a and the beam member 12 is substantially the same as the above-described configuration of the connection portion between the connection portion 22 and the beam member 12 in the outer column member 11b. That is, as shown in FIG. 7, the 1st connection member 51 which connects the center side column member 11a and the beam member 12 contains a volt | bolt, a nut, and a sleeve (all are not shown in figure). The central column member 11a and the beam member 12 partially overlap each other when viewed from the front, and bolts of the first connecting member 51 are inserted into through holes (not shown) formed in the central column member 11a and the beam member 12, respectively. And the sleeve are inserted, and then the nut is screwed onto the bolt. Thus, the central column member 11a and the beam member 12 are rotatably connected around the rotation axis of the bolt.

  In addition to the through hole for the first connecting member 51, a through hole is formed in each of the central column member 11 a and the beam member 12. The centers of these through holes coincide with each other when the beam member 12 is in the deployed position. When the centers of these through holes coincide with each other, a bolt as the first fixing member 53 is inserted in the same manner as the first fixing member 23 described above, and the beam member 12 is inserted into the central column member 11a. Is fixed.

  Of the four wire members 16 included in the second assembly unit 50, two wire members 16 are rotatably connected at one end to the upper end of the central column member 11a. The other end portions of the beam members 12 are connected to the connection portions 36 of the left and right first assembly units 20A when the cooling tower 1 is constructed and assembled. Further, of the four wire members 16 included in the second assembly unit 50, the remaining two wire members 16 each have one end portion rotatable to the two connection portions 52 of the central side column member 11a. It is connected. The other end portions of the beam members 12 are connected to the lower end portions of the intermediate column member 11c in the left and right first assembly units 20A when the cooling tower 1 is constructed and assembled.

  Next, the flow of construction and assembly of the cooling tower 1 using the first and second assembly units 20A and 50 described above will be described. First, the above-described cooling tower assembly units 20A and 50 are manufactured in a factory or the like. Further, in addition to the cooling tower assembly units 20A and 50, members necessary for assembling the tower frame 10 (for example, beam members 17 and 18 not included in the cooling tower assembly units 20A and 50) and the configuration of the cooling tower 1 are provided. Prepare the device that will be the element.

  Next, the first and second assembly units 20 </ b> A and 50 and other members and devices that are components of the cooling tower 1 are transported to the construction site. 8A shows the first assembly unit 20A in which the support member 13 is in the folded position with respect to the outer column member 11b, and the beam member 12 is in the folded position with respect to the outer column member 11b and the intermediate column member 11c. Indicates the state. As shown in FIG. 8A, the first assembly unit 20A transports both the support member 13 and the beam member 12 to the construction site in a state where both the support member 13 and the beam member 12 are rotated to the collapsed position.

  Further, as shown by the two-dot chain line in FIG. 7, the second assembly unit 50 rotates the beam member 12 to the folding position with respect to the central column member 11a, and the wire member 16 also changes to the central column member 11a. The product is transported to the construction site while being rotated to a parallel position.

  After transporting the first and second assembly units 20A, 50 and the like to the construction site, the tower frame 10 is assembled at the construction site.

  First, for the first assembly unit 20A, as shown in FIGS. 8B and 8C, both the support member 13 and the beam member 12 are rotated from the collapsed position to the deployed position. FIG. 8B shows the first assembly unit 20A in which the support member 13 is in the deployed position with respect to the outer column member 11b and the beam member 12 is in the folded position with respect to the outer column member 11b and the intermediate column member 11c. Indicates the state. As shown in FIG. 8B, after each support member 13 is moved from the folded position to the deployed position, each support member 13 is fixed to the outer column member 11b by the second fixing member 43.

  FIG. 8C shows the first assembly unit 20A in which the support member 13 is in the deployed position with respect to the outer column member 11b and the beam member 12 is in the deployed position with respect to the outer column member 11b and the intermediate column member 11c. Indicates the state. As shown in FIG. 8C, after each beam member 12 is moved from the folded position to the deployed position, the first fixing members 23 and 33 are used to fix each beam member 12 to the outer column member 11b and the intermediate column member 11c. Fix it. Thus, the first assembly unit 20A is held in a state in which the positional relationship among the outer column member 11b, the intermediate column member 11c, and the beam member 12 included in the first assembly unit 20A is the positional relationship when the cooling tower 1 is assembled.

  In the first assembly unit 20 </ b> A, it is not necessary to rotate the support member 13 first and fix it to the column member 11. That is, the beam member 12 may be rotated first and fixed to the column member 11.

  As for the second assembly unit 50, as shown in FIG. 7, after each beam member 12 is moved from the folded position to the deployed position, each beam member 12 is fixed to the central column member 11a by the first fixing member 53. To do. In this way, the second assembly unit 50 is held in a state in which the positional relationship between the central side column member 11a and the beam member 12 included in the second assembly unit 50 is the positional relationship when the cooling tower 1 is assembled.

  Next, the developed two first assembly units 20A and one second assembly unit 50 are connected to manufacture the intermediate unit 10a. After the three intermediate units 10a are manufactured, three intermediate units 10a are arranged so as to overlap when viewed from the front, and the adjacent intermediate units 10a are connected by the beam member 12. In this way, the tower frame 10 which becomes the framework part of the cooling tower 1 is assembled. The fan 2, the hot water tank 3, the filler 5 and the like are attached to the tower body 10, and the construction and assembly of the cooling tower 1 is completed.

  As described above, when the cooling tower assembly units 20A, 50 according to the present embodiment are transported from the factory or the like to the construction site, the beam member 12 is rotated to the folded position, and the cooling tower assembly unit 20A, 50 can be compactly conveyed. Further, at the construction site, the beam member 12 is rotated to the unfolded position, and the beam member 12 is fixed to the column member 11 by the first fixing members 23, 33, 53. The mutual positional relationship can be the positional relationship when the cooling tower 1 is assembled. Thereby, the cooling tower assembly units 20A, 50 fixed by the first fixing members 23, 33, 53 can be applied to a part of the cooling tower 1 as they are. For this reason, compared with the conventional construction assembly which connected the column member and beam member which were separately conveyed to the construction site in the construction site, the assembly time of the tower frame 10 in a construction site can be shortened.

  Further, in this embodiment, when the cooling tower assembly unit 20A is transported from the factory or the like to the construction site, the support member 13 is rotated to the folding position to transport the cooling tower assembly unit 20A in a compact form. Can do. Further, at the construction site, the support member 13 is rotated to the unfolded position, and the support member 13 is fixed to the outer column member 11b by the second fixing member 43, whereby the outer column member 11b and the support member 13 are mutually connected. The positional relationship can be the positional relationship when the cooling tower 1 is assembled. Thereby, the cooling tower assembly unit 20 </ b> A fixed by the second fixing member 43 can be applied to a part of the cooling tower 1 as it is. For this reason, the assembly time of the tower frame 10 in a construction site can be shortened compared with the conventional construction assembly which connected the pillar member and support member which were separately conveyed to the construction site in the construction site.

  In the present embodiment, the unfolding rotation restricting portion 24 abuts on the connecting portion 22 when the beam member 12 is at the unfolded position, and the unfolded position with respect to the unfolded position from the unfolded position to the opposite side. Regulates rotation. For this reason, it becomes easy to position the beam member 12 at the unfolded position when the cooling tower 1 is assembled.

  Further, in the present embodiment, the folding rotation restricting portion 35 is configured such that when the beam member 12 is in the collapsed position, the contact surface 35a abuts on the beam member 12, and from the collapsed position to the deployed position with respect to the collapsed position. Restricts the rotation of the beam member 12 to the opposite side. For this reason, unnecessary interference between the outer column member 11b, the intermediate column member 11c, and the beam members 12 that can occur when the beam member 12 is rotated from the folded position to the side opposite to the deployed position with respect to the folded position can be avoided. .

FIG. 10A is a view showing a state where the beam member 12 is in the folded position, and FIG. 10B is an enlarged view of the IXB portion of FIG. 9 showing a state where the beam member 12 is in the deployed position. .

  The hinge 62 included in the first connecting member 61 includes a fixed-side hinge part 63 fixed to the intermediate column member 11 c and a rotating-side hinge part 64 that moves relative to the fixed-side hinge part 63. The fixed-side hinge part 63 includes a first plate 63c fixed to the intermediate column member 11c by a bolt 63a and a nut 63b screwed to the bolt 63a, and two first annular rings 63d are coaxial with the first plate 63c. It is provided in the shape. Similarly, the rotation-side hinge part 64 includes a second plate body 64a, and the second plate body 64a is provided with one second annular ring 64b. A second annular ring 64b is disposed between the two first annular rings 63d, and the shaft 65 passes through the first annular ring 63d and the second annular ring 64b. The fixed side hinge part 63 and the rotation side hinge part 64 are rotatable about the rotation axis C4 of the shaft body 65.

  The second plate body 64a and one end of the beam member 12 are connected by a connection member 66 having a substantially H-shaped cross section. The connection member 66 is a place where the eliminator 8 is placed when the cooling tower 1 is assembled and assembled. That is, at the time of construction and assembly of the cooling tower 1, the edge of the long plate-like eliminator 8 enters the concave portion opened upward in the connection member 66. And the eliminator 8 is fixed to the intermediate | middle column member 11c in the state arrange | positioned along the intermediate | middle column member 11c.

  Further, the first assembly unit 20B includes a first fixing member 67 that fixes the beam member 12 to the intermediate column member 11c when the beam member 12 is in the deployed position with respect to the intermediate column member 11c. Specifically, as shown in FIG. 10B, the first fixing member 67 includes a bolt 67a and a nut 67b screwed to the bolt 67a. The first plate 63c and the second plate 64a are formed with through holes 68a and 68b (corresponding to “holding holes” in the present invention), respectively. The centers of the through holes 68a and 68b coincide with each other when the beam member 12 is in the deployed position. When the centers of the through holes 68a and 68b coincide with each other, a bolt 67a is inserted into the through holes 68a and 68b and a nut 67b is screwed as shown in FIG. The beam member 12 is kept in the deployed position with respect to the column member 11b.

  The first connecting member 71 has a configuration similar to that of the first connecting member 61 except that the first connecting member 61 does not include the connecting member 66 on which the eliminator 8 is placed. Therefore, the description is omitted.

  Also in the first assembly unit 20B according to this modification, the same effect as that of the first assembly unit 20A can be obtained.

Second Embodiment
Next, the cooling tower assembly unit 80 according to the second embodiment will be described with reference to FIGS. 11 and 12. FIG. 11 is a front view of the cooling tower assembly unit 80 according to the second embodiment. FIG. 11 (A) shows a state in which the beam member 12 is in the folded position, and FIG. 11 (B) shows the beam member. 12 shows a state in the deployed position.

  The cooling tower assembly unit 80 of this embodiment is also used for assembling the tower frame 10 described in the first embodiment. The cooling tower assembly unit 80 corresponds to one central column member 11a (corresponding to the “first column member” of the present invention) and two intermediate column members 11c (corresponding to the “second column member” of the present invention). ), A first beam member 81 coupled to the central column member 11a, and a second beam member 82 coupled to the intermediate column member 11c.

  The cooling tower assembly unit 80 includes a first beam-beam connecting member 83 that connects the first beam member 81 so as to be rotatable with respect to the central column member 11a, and a first beam member with respect to the central column member 11a. A first column-beam fixing member 84 for fixing 81 is provided. The cooling tower assembly unit 80 includes a second column-beam connecting member 85 that connects the second beam member 82 to be rotatable with respect to the intermediate column member 11c, and a second beam member with respect to the intermediate column member 11c. A second column-beam fixing member 86 for fixing 82 is provided. The first column-beam connecting member 83 and the second column-beam connecting member 85 have the same configuration as that of the first connecting member 51 of the first embodiment. The two-column-beam fixing member 86 has the same configuration as that of the first fixing member 53 of the first embodiment. Therefore, description of the first column-beam connecting member 83, the first column-beam fixing member 84, the second column-beam connecting member 85, and the second column-beam fixing member 86 is omitted.

  The cooling tower assembly unit 80 includes a beam-beam connecting member 91 and a beam-beam fixing member 92. The beam-to-beam connecting member 91 is a second beam with respect to the first beam member 81 in a state where the first beam member 81 and the second beam member 82 are disposed between the central column member 11a and the second column member. The member 82 is rotatably connected. The beam-beam fixing member 92 fixes the second beam member 82 to the first beam member 81 when the second beam member 82 is positioned on the straight line in which the first beam member 81 extends.

  12A is an enlarged view of the XIA portion of FIG. 11A, and FIG. 12B is an enlarged view of the XIB portion of FIG. 11B. The configuration of connecting the first beam member 81 and the second beam member 82 by the beam-beam connecting member 91 is substantially the same as the configuration of connecting the column member 11 and the beam member 12 described in the above embodiment. That is, as shown in FIG. 12A, the beam-beam connecting member 91 includes a bolt 91a, a nut and a sleeve (not shown). The first beam member 81 and the second beam member 82 partially overlap each other when viewed from the front. Bolts 91a and bolts 91a are inserted into through holes (not shown) formed in the first beam member 81 and the second beam member 82, respectively. The sleeve is inserted, and then the nut is screwed onto the bolt 91a. Thus, the first beam member 81 and the second beam member 82 are rotatably connected around the rotation axis C5 of the bolt 91a.

  The first beam member 81 and the second beam member 82 are each formed with a through hole 92a separately from the through hole through which the bolt 91a is inserted. The centers of the through holes 92a coincide with each other when the second beam member 82 is positioned on the straight line on which the first beam member 81 extends. Then, when the centers of the through holes 92a coincide with each other, a bolt (not shown) as the beam-beam fixing member 92 is inserted in the same manner as the first fixing member 23 described above, and the first beam member 81 is inserted. And the second beam member 82 are fixed.

  Also in the present embodiment, the first column-beam connecting member 83, the first column-beam fixing member 84, the second column-beam connecting member 85, and the second column-beam fixing member 86 are the same as those in the first embodiment. An effect can be obtained.

  Moreover, in this embodiment, the space | interval of the center side column member 11a and the intermediate | middle column member 11c in the cooling tower assembly unit 80 can be narrowed, and the cooling tower assembly unit 80 can be compactly conveyed. Further, at the construction site, when the interval between the central column member 11 a and the intermediate column member 11 c in the cooling tower assembly unit 80 is widened, the second beam member 82 is positioned on the straight line in which the first beam member 81 extends. In order to fix the second beam member 82 to the first beam member 81 by the beam-beam fixing member 92, the interval between the center side column member 11a and the intermediate column member 11c is set to the interval at the completion of the assembly of the cooling tower. Can be. For this reason, compared with the conventional construction assembly which connected the several pillar member conveyed separately to the construction site by the beam member at the construction site, the assembly time of the tower frame 10 in a construction site can be shortened.

  Also in this embodiment, as in the first embodiment, the column member 11 or the beam member 12 has a rotation restriction for deployment that restricts the rotation of the beam member 12 within a predetermined range with respect to the column member 11. And a folding restricting portion for folding may be provided. The first beam member 81 or the second beam member 82 may be provided with a rotation restricting portion that restricts the rotation of the second beam member 82 within a predetermined range with respect to the first beam member 81. Good.

<Other embodiments>
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, the connecting member (the first connecting member 21 or the like) that connects the column member 11 and the beam member 12 or the connecting member (the beam-beam connecting member 91) that connects the beam members 12 to each other is not limited to the above-described configuration. . For example, the connecting member may not include a sleeve. In this case, the pivotable coupling of the column member 11 and the beam member 12 is realized by appropriately adjusting the tightening torque of the bolt in the coupling member or by screwing the bolt with the nut loosened. . The connecting member may have a pin inserted through the through hole instead of the bolt.

  Moreover, in the said embodiment, although the assembly unit for cooling towers was the structure which rotates the beam member 12 extended in the left-right direction of the tower frame 10 with respect to the column member 11, it is not limited to this. For example, the cooling tower assembly unit may be configured to rotate the beam member 12 ′ (see FIG. 2) extending in the front-rear direction of the tower body 10 with respect to the column member 11.

  Moreover, the assembly unit for cooling towers should just be provided with the at least 1 pillar member 11 and the at least 1 beam member 12 or 12 '. For example, the first assembly unit 20 </ b> A has two beam members 12, but may have one or three or more beam members 12.

  The configuration of the tower 10 is not limited to that described in the above embodiment. For example, the tower body 10 may not be configured to include the three intermediate units 10a. Further, the intermediate unit 10a has five column members 11 and two beam members 12, but the number and positions of the column members 11 and beam members 12 in the intermediate unit 10a are as follows. It is not limited to what was demonstrated by the said embodiment. For example, the intermediate unit 10a may be configured to include four column members excluding the central column member. In this case, one beam member may connect 11c to each other. The intermediate unit 10a may be configured by one cooling tower assembly unit.

  However, as shown in FIG. 2, the tower body 10 has a structure in which the pillar member 11 (that is, the central side pillar member 11 a) coincides with the drive shaft of the fan 2 when the tower body 10 is viewed in plan. It is preferable to do. This is because the vibration of the entire cooling tower 1 can be reduced according to this configuration. Further, three intermediate units 10a described in the above embodiment are arranged at equal intervals in the front-rear direction, and the intermediate units 10a adjacent in the front-rear direction are connected by a plurality of beam members 12 'extending in the front-rear direction. Is particularly preferred. According to this configuration, it is possible to realize a tower body that has sufficient strength to support the above-described devices included in the cooling tower 1 with a small number of members.

  Moreover, in the said embodiment, although the connection part 22 was provided in the outer pillar member 11b and the connection part 32 was provided in the intermediate | middle pillar member 11c, these connection parts 22 and 32 may not be provided. In this case, the through hole 22a through which the bolt 21a is inserted may be provided in the main body portion of the column member 11.

  The cooling tower assembly unit may include a fixing member that fixes the beam member 12 in the folded position to the column member 11. That is, the beam member 12 and the column member 11 are provided with a through hole whose center coincides when the beam member 12 is in the folded position, and a bolt or a pin as a fixing member is inserted into the through hole so that the state of the folded position is obtained. It may be maintained.

  In the above embodiment, the cooling tower assembly unit used for assembling the cross flow cooling tower 1 in which the flow of hot water and the flow of cooling air are orthogonal to each other has been described. The present invention is also applicable to the assembly of a counter flow type cooling tower 1 that performs heat exchange between rising cooling air and falling hot water.
