Description

[Technical field]

[0001] The present invention relates to a technique for a pipe support structure that supports a pipe connected to a feedwater pump. [Background technology]

[0002] Generally, water supply pumps for supplying water to the upper floors of a building are installed in a dedicated pump room. Water supply pumps generate large vibrations when in operation. For this reason, water supply pumps are usually installed on vibration-proof stands. This reduces the transmission of vibrations from the water supply pump itself to the building's framework.

[0003] However, the vibration of the feedwater pump is also transmitted to the piping connected to the feedwater pump. For this reason, a pipe silencer or the like is sometimes installed between the feedwater pump and the piping to prevent the vibration from being transmitted to the piping, but this does not significantly reduce the vibration generated by the water flow in the piping.

[0004] Therefore, as described in Patent Document 1, it is possible to take measures against vibration of the pipes by supporting the pipes on a dedicated stand in the same way as the feedwater pump. However, since there are various layouts of the pipes, it is not easy to adjust the support position of the pipes on site (in the pump room). [Prior art documents] [Patent documents]

[0048] The sixth flat portion 60b shown in Fig. 3 is formed to protrude leftward from the upper end of the fifth flat portion 60a. The sixth flat portion 60b is formed in a substantially rectangular plate shape in a plan view, and is provided with the plate surface facing the up-down direction. The pipe P extending in the left-right direction is fixed to the upper surface of the sixth flat portion 60b by an appropriate method.

[0049] The second left-right position adjustment portion 70 shown in FIG. 1 and FIG. 4 supports the second pipe support portion 80 described later and adjusts the left-right position of the second pipe support portion 80. The second left-right position adjustment portion 70 is provided on the lower horizontal support member 40b. The second left-right position adjustment portion 70 is provided as a pair with a space between them. The left and right second left-right position adjustment portions 70 are formed symmetrically with each other. For this reason, the following description will be mainly focused on the right second left-right position adjustment portion 70, and the description of the left second left-right position adjustment portion 70 will be omitted as appropriate. A pair of left and right second left-right position adjustment portions 70 are provided on the lower horizontal support member 40b. The second left-right position adjustment portion 70 includes a horizontal slide member 71 and an inner fixing plate 72.

[0050] The lateral slide member 71 is provided on the outer side of the lower horizontal support member 40b. The lateral slide member 71 is formed in a substantially L-shape when viewed from the front. The lateral slide member 71 includes a seventh flat portion 71a and an eighth flat portion 71b.

[0051] The seventh flat portion 71a shown in Fig. 4 is formed in a substantially rectangular plate shape in a plan view, and is provided with the plate surface facing the up-down direction. The seventh flat portion 71a is provided along the outer surface of the lip portion 41b of the lower horizontal support member 40b (so as to abut against the outer surface of the lip portion 41b). The seventh flat portion 71a is provided so as to close the opening (between the front and rear lip portions 41b) of the lower horizontal support member 40b.

The inner fixing plate 72 is provided so as to close the opening of the lower horizontal support member 40b (between the front and rear lip portions 41b).

[0054] The lateral slide member 71 and the inner fixed plate 72 thus formed are fixed to each other with a bolt 73 and a nut 74, with the lip portion 41b of the lower horizontal support member 40b sandwiched therebetween. The bolt 73 is inserted into the opening of the lower horizontal support member 40b (between the front and rear lip portions 41b), and the nut 74 is fastened to the tip of the bolt 73, thereby fixing the seventh flat portion 71a of the lateral slide member 71 and the inner fixed plate 72 to the lower horizontal support member 40b.

[0055] As a result, the lateral slide member 71 and the inner fixing plate 72 can slide in the longitudinal direction (left-right direction) of the lower horizontal support member 40b by loosening the bolts 73 and the nuts 74. Therefore, the lateral slide member 71 and the inner fixing plate 72 can be fixed to the lower horizontal support member 40b at any position in the longitudinal direction (left-right direction) of the lower horizontal support member 40b.

[0056] The second pipe support portion 80 supports the pipe P via an attachment 90 described later. The second pipe support portion 80 is formed in a substantially L-shape when viewed from the front. The second pipe support portion 80 is provided on each of the multiple second left / right position adjustment portions 70. As shown in FIG. 4(a), the second pipe support portion 80 is formed so as to protrude forward further than the lower horizontal support member 40b and the lateral slide member 71. The second pipe support portion 80 includes a ninth flat portion 80a and a tenth flat portion 80b.

[0057] 4 is formed in a generally rectangular plate shape in a side view, with the plate surface facing in the left-right direction. The ninth flat portion 80a is provided along the left surface of the eighth flat portion 71b of the lateral slide member 71 (so as to abut against the left surface of the eighth flat portion 71b). The ninth flat portion 80a is fixed to the eighth flat portion 71b of the lateral slide member 71 by a bolt 81 and a nut 82.

[0058] The tenth planar portion 80b shown in Fig. 4 is formed so as to protrude leftward from the upper end of the ninth planar portion 80a. The tenth planar portion 80b is formed in a substantially rectangular plate shape in a plan view, and is provided with the plate surface facing in the up-down direction. An attachment 90, which will be described later, is provided on the upper surface of the tenth planar portion 80b.

[0059] 1 and 4 is for fixing the pipes P. The attachment 90 is formed in a substantially L-shape when viewed from the side. The attachment 90 is removably provided to the second pipe support part 80. A plurality of types (shapes) of attachments 90 are prepared according to the layout (position and number) of the pipes P. For example, the attachment 90 includes an eleventh flat portion 90a and a twelfth flat portion 90b.

[0060] 4 is formed in a substantially rectangular plate shape in a plan view, and is provided with the plate surface facing the up-down direction. The eleventh flat portion 90a is in contact with and fixed to the upper surface of the tenth flat portion 80b of the second pipe support portion 80.

[0061] The twelfth flat portion 90b shown in Fig. 4 is formed so as to protrude upward from the front end of the eleventh flat portion 90a. The twelfth flat portion 90b is formed in a substantially rectangular plate shape in a front view, and is provided with the plate surface facing in the front-rear direction. The piping P extending in the vertical direction is fixed to the front surface of the twelfth flat portion 90b by an appropriate method.

[0062] The pipe P is supported by the pipe support structure 1 configured as described above. The vertical positions of the horizontal support members 40 (upper horizontal support member 40a and lower horizontal support member 40b) can be adjusted to any position (height) by the vertical position adjustment unit 20. Therefore, the pipe support structure 1 can support the pipe P at any height.

[0063] Furthermore, the left and right position of the first pipe support part 60 can be adjusted to any position by the first left and right position adjustment part 50. Furthermore, the left and right position of the second pipe support part 80 (attachment 90) can be adjusted to any position by the second left and right position adjustment part 70. Therefore, the pipe support structure 1 can support the pipe P at any left and right position.

[0064] In this way, the pipe support structure 1 can arbitrarily adjust the support position of the pipe P in the vertical and horizontal directions, so that the support position of the pipe P can be changed on-site according to the layout of the pipe P. This eliminates the need to design a frame according to various layouts of the pipe P.

[0065] Furthermore, in the pipe support structure 1, the vibration-proof rubber 30 is provided between the vertical slide member 21 and the horizontal support member 40. This makes it possible to suppress the vibration of the pipe P transmitted from the water supply pump from being transmitted from the horizontal support member 40 to the support column 10. This makes it possible to suppress the vibration of the pipe P from being transmitted to the building framework.

[0066] In addition, since the horizontal support members 40 support multiple pipes P, it is not necessary to provide vibration isolation for each pipe P. Also, the support load can be designed to be relatively large compared to when each pipe P is vibration isolated. This allows the spring constant of the vibration isolation rubber 30 to be increased while the natural frequency is set low. Therefore, it is possible to suppress the propagation of vibration while maintaining both practicality and durability.

[0067] Furthermore, since the pipe support structure 1 according to this embodiment is configured by erecting the support pillars 10 between the wall W and the pipe P, it is possible to make the structure compact.

[0068] Moreover, in the pipe support structure 1 according to this embodiment, the pipes P extending in the horizontal direction can be supported by the first pipe support part 60, and the pipes P extending in the vertical direction can be supported by using the attachment 90. Moreover, by preparing a plurality of attachments 90 with different shapes, it is possible to accommodate various layouts of the pipes P. For example, as shown in Fig. 6, the attachment 90A can also support a plurality of pipes P extending in the horizontal direction lined up above each other.

[0069] In addition, because the support pillar 10 is made of C-shaped steel, a single part can serve both to support the horizontal support member 40 and to slide the vertical slide member 21. This reduces the number of parts and the cost. Similarly, because the horizontal support member 40 is made of C-shaped steel, the number of parts and the cost can be reduced.

[0070] As described above, the pipe support structure 1 according to this embodiment has the following features: A piping support structure 1 that supports a piping P connected to a water supply pump installed in a building, A support 10 (first support portion) fixed to a floor X (framework) of the building; A horizontal support member 40 (second support portion) supported by the support column 10 so as to be slidable in the vertical direction (first direction); A first pipe support portion 60 and a second pipe support portion 80 (pipe support portion) that are supported by the horizontal support member 40 so as to be slidable in the left-right direction (a second direction different from the first direction) and support the pipe P; a vibration-isolating rubber 30 (vibration-isolating member) provided between the support 10 and the horizontal support member 40 to suppress the vibration of the piping P from being transmitted from the horizontal support member 40 to the support 10; It is equipped with the following.

[0071] With this configuration, it is possible to prevent vibrations from the water supply pump from being transmitted to the building structure via the piping P, and the support position of the piping P can be easily adjusted according to the layout of the piping P.

[0072] In addition, the support 10 is The flange is formed of a C-shaped steel having a lip portion 11. The horizontal support member 40 is The support 10 supports the lip portion 11 so as to be slidable along the lip portion 11 .

[0073] With this simple configuration, the horizontal support member 40 and the first pipe support portion 60 and the second pipe support portion 80 supported by the horizontal support member 40 can be slid in the vertical direction (first direction).

[0074] In addition, the horizontal support member 40 is The vertical position adjustment part 20 (slide member) is supported by the support 10 via the vertical position adjustment part 20 (slide member) that is slidable in the vertical direction. The vertical position adjustment unit 20 is A vertical slide member 21 (outer member) is provided on the outer side of the lip portion 11 of the support column 10 and supports the horizontal support member 40 via the vibration isolating rubber 30; An inner fixing plate 22 (inner member) provided on the inner side of the lip portion 11 of the support 10 so as to sandwich the lip portion 11 between the vertical slide member 21 and the inner fixing plate 22 (inner member); It is equipped with the following.

[0075] With this simple configuration, the horizontal support member 40 and the first pipe support portion 60 and the second pipe support portion 80 supported by the horizontal support member 40 can be slid in the vertical direction (first direction).

[0076] In addition, the first pipe support portion 60 and the second pipe support portion 80 are A plurality of such support members are provided for each horizontal support member 40.

[0077] With this configuration, a single vibration-proof rubber 30 can be used to prevent vibrations in a plurality of pipes P.

[0078] In addition, the horizontal support member 40 is The lip portion 41 is formed of a C-shaped steel. The first pipe support portion 60 and the second pipe support portion 80 are The horizontal support member 40 supports the lip portion 41 so as to be slidable along the lip portion 41 .

[0079] With such a simple configuration, the first pipe support portion 60 and the second pipe support portion 80 can be slid in the left-right direction (second direction).

[0080] Although the embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0081] For example, in this embodiment, the support position of the pipe P can be adjusted (slid) in the vertical and horizontal directions, but the sliding direction of the support position of the pipe P is not limited and may be, for example, the vertical and front-to-back directions.

[0082] In the present embodiment, the lateral slide member 51 and the first pipe support portion 60 are separate members, but may be formed of a single member. Similarly, the lateral slide member 71 and the second pipe support portion 80 may be formed of a single member.

[0083] Further, the support pillar 10 is set upright on the floor X in the above embodiment, but may be set up on the wall W.

[0084] Furthermore, when the vertical position adjustment part 20 is fixed to the support 10, the inner fixing plate 22 can be inserted into the inside of the support 10 from the longitudinal end of the support 10 (C-shaped steel), but it may also be inserted into the inside of the support 10 from an opening of the support 10 (between the front and rear lip parts 11) as shown in FIG. 7. Specifically, the inner fixing plate 22 is formed so that its width in one direction is narrower than the opening width of the C-shaped steel support 10, and is formed so as to be rotatable around an axis extending in the left-right direction. After inserting the inner fixing plate 22 into the inside of the support 10 from the opening of the support 10 (see FIG. 7(a)), the inner fixing plate 22 can be easily attached to the support 10 by rotating it around the axis (see FIG. 7(b)).

[0085] As described above, the inner fixing plate 22 is The support rod 10 is formed so that it can be inserted into the inside of the support rod 10 through the opening between the lip portions 11, and cannot be removed from the opening to the outside of the support rod 10 by rotating the support rod 10.

[0086] With this configuration, the inner fixing plate 22 can be easily attached to the support 10. [Explanation of symbols]
