Description

The present invention relates to a pipe support structure, and more particularly to a pipe support structure that supports a pipe provided with a pipe lug.

As a pipe support structure for supporting a pipe provided with a pipe lug, for example, in Patent Document 1, a notch is formed in a lug welded to the outer peripheral surface of the pipe, and a horizontal beam of the support structure is engaged with the notch. A pipe restraint support that restrains and supports a pipe in the pipe axis direction and the pipe diameter direction is disclosed.
Further, Patent Document 2 describes a pipe supporting means for restraining a pipe in the pipe axial direction by sandwiching a pipe lug welded to the pipe between rib plates of a pipe lug attachment provided on the upper and lower horizontal beams of the support structure. It is disclosed.

Japanese Unexamined Patent Publication No. 2011-64288 Japanese Unexamined Patent Publication No. 9-170680

In Patent Document 1, since the shape of the notch is formed according to the shape of the horizontal beam of the supporting structure to be engaged, the pipe is constrained in the pipe axial direction and the pipe radial direction. Therefore, when a load in the pipe axial direction and the pipe radial direction is applied to the pipe due to thermal expansion displacement or earthquake displacement of the pipe, the pipe may be deformed or damaged.

On the other hand, in the form of FIGS. 5 to 7 of Patent Document 2, a gap is formed between the upper end and the left and right ends of the pipe lug and the support structure to allow thermal expansion displacement and seismic displacement of the pipe. However, as shown in FIG. 7 and its description of the document, there is no gap between the lower end of the piping lug and the support structure. Therefore, at least a part of the weight of the pipe and the pipe support structure is always applied to the lower end of the pipe lug, and the pipe is restrained downward in the pipe radial direction.

If the pipe is restrained downward in the pipe radial direction, the pipe may be deformed or damaged when a downward load in the pipe radial direction is applied to the pipe due to thermal expansion displacement or seismic displacement of the pipe. As described above, direct and excessive restraint of the pipe as described in Patent Documents 1 and 2 may cause the pipe to be deformed or damaged due to thermal expansion displacement or seismic displacement of the pipe. There was a need for a pipe support structure that was constructed to restrain only and prioritize the protection of pipes.

Further, due to the structure required for the pipe support structure, it may be desired to allow the displacement of the pipe only in the pipe axial direction. However, since the pipe support structures of Patent Documents 1 and 2 are structured so that not only the pipe axial direction but also the pipe radial direction is constrained, there still remains a problem in improving the degree of freedom in structural design. No special consideration has been given to improving the workability and reliability of the pipe support structure.

The present invention has been made in view of such a problem, and an object of the present invention is to protect the pipe by restraining the pipe only when necessary while improving the degree of freedom in design, workability and reliability. The purpose is to provide a piping support structure that can be prioritized.

In order to achieve the above object, the first aspect of the present invention is a pipe support structure for supporting a pipe, which projects from the outer peripheral surface of the pipe in the pipe radial direction along the circumferential direction and faces the pipe axis direction.

A third aspect of the present invention includes a pipe support that faces the outer peripheral surface of the pipe in the pipe radial direction with a second radial gap.

In the fourth aspect of the present invention, the pipe lug projects from the outer peripheral surface of the pipe in the pipe radial direction along the circumferential direction thereof, and has a shape similar to the cross-sectional shape of the pipe.

In the fifth aspect of the present invention, the pipe lug has a shape in which a plurality of points project from the outer peripheral surface of the pipe along the circumferential direction in the pipe radial direction.

In the sixth aspect of the present invention, the pipe lug is integrally formed on the outer peripheral surface of the pipe by forging.

A seventh aspect of the present invention is a plurality of columns erected on a foundation or structure, a plurality of beams joined on each column, and a column or beam joined to a column or beam toward a pipe lug.

<First Embodiment>
FIG. 1 is a perspective view showing a pipe support structure according to a first embodiment of the present invention. Hereinafter, in FIG. 1, of the pipe axial directions X of the pipe 12, the direction toward the lower left side of the figure is the left direction, and the direction toward the upper right side of the figure is the right direction. Further, in the pipe radial direction Y of the pipe 12, the direction toward the upper side of the figure is the upward direction, and the direction toward the lower side of the figure is the downward direction. Further, in the pipe radial direction Z of the pipe 12, the direction toward the upper left side in the figure is the back direction, and the direction toward the lower right side in the figure is the front direction. Hereinafter, the description will be made on the premise of this positional relationship. This pipe support structure includes a support 1 that supports pipes laid in various plants only when the pipes are displaced.

The support 1 is provided, for example, by being joined onto a structure 2 placed in a building. The structure 2 is installed on the foundation 6 in the building and is supported by the wall 8 in the building, and is passed through a space surrounded by a plurality of columns and beams constituting the structure 2. Supports the horizontally laid pipe 4. It should be noted that the joining means and the fixing means accompanied by the installation of the respective constituent members of the structure 2 and the support 1 described below are mainly welding.

The support 1 includes, for example, four columns 1a and four beams 1b, and the lower end of each column 1a is joined and erected on the structure 2. The two beams 1b facing each other are placed on the upper end of each column 1a and joined to each other, and are supported by the wall 8. The remaining two beams 1b are joined between these two beams 1b.

In the support 1, a pipe 12 laid horizontally and provided with a pipe lug 10 is passed through a space surrounded by each pillar 1a, each beam 1b, and a structure 2. The pipe 12 is mounted on the structure 2 or is configured so that a beam of another structure (not shown) receives the load of the pipe 12. Therefore, the support 1 is constructed so as to support the pipe lug 10 only when the pipe 12 is displaced, to restrain the pipe 12 only when necessary, and to give priority to the protection of the pipe 12.

Specifically, the support 1 has a pair of lug supports 14 facing the pipe axial direction X of the pipe 12 toward the pipe lug 10, and a pipe radial direction Y and a pipe radial direction of the pipe 12 toward the pipe 12. A plurality of sets of a pair of piping supports 16 facing the Z are provided. More specifically, in the support 1, the pair of lug supports 14 are two sets for each pillar 1a facing the pipe axis direction X, one set for each beam 1b facing the pipe axis direction X, and facing the pipe axis direction X. A total of four sets are joined to each component of the structure 2 to be formed. Further, the pair of piping supports 16 are joined to a total of four sets, two sets for each column 1a facing the pipe radial direction Z, and two sets for the beam 1b facing the pipe radial direction Y and the constituent members of the structure 2. There is.

In FIG. 2, (a) is a partial cross-sectional view of the support 1 when a vertical cross section passing through the center of the pipe 12 is viewed from the direction A of FIG. 1, and (b) is a partial cross-sectional view of the pipe 12 in FIG. 2 (a). It is a cross-sectional view when viewed from the BB direction, and (c) is a partial cross-sectional view of the pipe 12 and the support 1 when viewed from the BB direction of FIG. 2 (a). As shown in FIGS. 2A and 2B, the pipe lug 10 has a disk shape protruding from the outer peripheral surface 12a of the pipe 12 in a direction orthogonal to the pipe axis direction X along the circumferential direction thereof, and is a pipe. It is integrally formed on the outer peripheral surface 12a of 12 by forging. Pressure receiving surfaces 10a are formed on both sides of the piping lug 10 facing the pipe axis direction X.

Here, each lug support 14 of the present embodiment has each pressure receiving surface 10a in the pipe axial direction X and a supporting surface 14a facing each other with an axial gap G1. Further, each lug support 14 is arranged at a position that does not overlap with the outer peripheral edge 10b of the pipe lug 10 when viewed from a direction orthogonal to the pipe radial direction X. In other words, when the pipe 12 is viewed from the direction orthogonal to the pipe radial direction X, the outer peripheral edge 10b of the pipe lug 10 is not covered with each lug support 14, and an open space exists outside the outer peripheral edge 10b. That is, the pipe lug 10 does not interfere with each lug support 14 in the direction orthogonal to the pipe axial direction X. Further, each lug support 14 has a side surface 14b facing the outer peripheral surface 12a of the pipe 12 with a radial gap (first radial gap) G2.

On the other hand, each pipe support 16 has a support surface 16a facing the outer peripheral surface 12a of the pipe 12 with a radial gap (second radial gap) G3. The above-mentioned gaps G1 to G3 are set to a size that allows a relatively small displacement of the pipe lug 10 due to thermal expansion of the pipe 12 or the like. As a result, even if the pipe lug 10 is displaced relatively small in the pipe axial direction X due to thermal expansion of the pipe 12, the pipe lugs on both the left and right sides along the pipe axial direction X due to the presence of the axial gap G1. Contact between the 10 and the lug support 14 is avoided, and no load acts on the pipe 12.

Further, even if the pipe lug 10 is displaced relatively small in the direction orthogonal to the pipe axial direction X due to thermal expansion of the pipe 12, the pipe is due to the existence of the open space outside the outer peripheral edge 10b of the pipe lug 10. Contact between the pipe lug 10 and the lug support 14 in the direction orthogonal to the axial direction X is avoided, and no load acts on the pipe 12. However, when the pipe 12 is largely displaced due to an earthquake or the like, the pipe 12 is restrained by the lag support 14 and the pipe support 16. Further, by forming the above-mentioned gaps G1 to G3 in the support 1, it is possible to promote heat dissipation from the pipe 12 and the pipe lug 10.

As shown in FIG. 2C, a contact region 14c is positioned on the support surface 14a of each lug support 14 so as to be in contact with the pressure receiving surface 10a when the pipe 12 is displaced. The ratio of the area of the contact region 14c to the area of the support surface 14a is preferably 30% or more, more preferably 50% or more and 70% or less.

As described above, in the pipe support structure of the present embodiment, the support surface 14a of each lug support 14 faces each pressure receiving surface 10a of the pipe lug 10 in the pipe axial direction X with an axial gap G1. Further, each lug support 14 is arranged at a position that does not overlap with the outer peripheral edge 10b of the pipe lug 10 when viewed from a direction orthogonal to the pipe radial direction X. As a result, a relatively small displacement due to thermal expansion of the pipe 12 is allowed by the axial gap G1 in any direction of the pipe axial direction X, while it is allowed in any direction orthogonal to the pipe radial direction X. It is allowed by the open space existing outside the outer peripheral edge 10b of the piping lug 10. Therefore, it is possible to realize a pipe support structure in which the pipe 12 is restrained only when it is necessary to restrain the pipe 12, and the protection of the pipe 12 is prioritized at other times.

Further, since the displacement of the pipe 12 in the direction orthogonal to the pipe radial direction X is allowed in the open space existing outside the outer peripheral edge 10b of the pipe lug 10, the pipe axial direction is required due to the structure of the pipe support structure. Since it is possible to handle the case where only X is desired to be restrained, the degree of freedom in designing the pipe support structure can be improved.
Further, the side surface 14b of each lug support 14 faces the outer peripheral surface 12a of the pipe 12 with a radial gap G2. As a result, it is possible to prevent the pipe 12 itself from coming into contact with the lug support 14 due to the displacement of the pipe 12, so that the pipe 12 can be protected more effectively.

Further, when the pipe 12 is displaced, the area ratio of the contact region 14c of the pressure receiving surface 10a of the pipe lug 10 to the support surface 14a of the lug support 14 is preferably 30% or more, more preferably 50% or more and 70% or less. By doing so, a large pressure receiving area of the piping lug 10 with respect to the lug support 14 is secured. As a result, when the pipe 12 is displaced, the load in the pipe axial direction X applied when the pressure receiving surface 10a of the pipe lug 10 comes into contact with the support surface 14a of the lug support 14 is applied to the surface pressure by the support surface 14a of the lug support 14. You can receive it while reducing it.

Moreover, by securing a large pressure receiving area, it is possible to increase the friction caused by the surface contact when the pressure receiving surface 10a of the piping lug 10 comes into contact with the support surface 14a of the lug support 14. Thereby, the displacement of the pipe 12 in the direction orthogonal to the pipe axis direction X can be effectively regulated. That is, by securing a large pressure receiving area as a contact region 14c on the support surface 14a of the lug support 14, it is possible to receive a load in the pipe axial direction X on the support surface 14a while reducing the surface pressure, and the surface. Since the displacement of the pipe 12 in the direction orthogonal to the pipe axial direction X can be effectively regulated by the friction caused by the contact, the pipe 12 can be protected even more effectively.

Further, the pipe lug 10 of the present embodiment is compact in the pipe axial direction X by forming a disk shape protruding from the outer peripheral surface 12a of the pipe 12 in a direction orthogonal to the pipe axial direction X along the circumferential direction thereof. A pipe support structure can be constructed. Further, when the pipe support structure is newly installed or renewed, the work range can be narrowed, so that the workability when constructing the pipe support structure is improved. Further, by forming the pipe into a simple disk shape, there is an advantage that the processing and molding of the pipe lug 10 on the pipe 12 can be performed at low cost.

Further, since the pipe lug 10 is integrally formed on the outer peripheral surface 12a of the pipe 12 by forging, the strength of the pipe lug 10 can be increased, and the pipe 12 is deformed due to welding, and the pipe is caused by the welding deformation. 12 damage can be prevented. Further, since the pipe 12 does not have a welded portion, the risk of damage to the pipe 12 based on the residual stress of the welded portion or the like can be reduced, and the reliability of the pipe support structure can be further improved.

<Second Embodiment>
FIG. 3 is a diagram showing a pipe support structure according to a second embodiment of the present invention. In FIG. 3, (a) shows a partial cross-sectional view of the pipe 12 when viewed from the direction corresponding to BB in FIG. 2 (a), and FIG. 3 (b) shows the pipe 12 and the support 1 in FIG. 2 (a). A partial cross-sectional view when viewed from the direction corresponding to BB is shown. As shown in FIG. 3A, the pipe lug 18 of the present embodiment has a cross shape protruding from the outer peripheral surface 12a of the pipe 12 along the circumferential direction in the pipe radial direction Y and the pipe radial direction Z. .. Regarding the same configuration as that of the first embodiment, the same reference numerals as those of the first embodiment may be added to the drawings to omit the description.

The pipe lug 18 is formed with a pressure receiving surface 18a on each tip side forming a cross shape, and an arc-shaped outer peripheral edge 18b that is concave toward the pipe 12 side at the outer end of the pipe lug 18 connecting the respective ends. Is formed. As shown in FIG. 3B, in the space through which the pipe 12 is passed in the support 1, a space 20 is formed between the outer peripheral edge 18b of the pipe lug 18 and the constituent members of the support 1. ..

As described above, the pipe support structure of the present embodiment restrains the pipe 12 only when necessary while improving the degree of freedom in design, workability, and reliability, as in the case of the first embodiment. Protection can be prioritized. In particular, in the case of the present embodiment, since the space 20 can be secured in the support 1 by providing the cross-shaped piping lug 18, when the constituent members of the support 1 are joined by welding or the like. Workability is improved, and workability when constructing a pipe support structure can be further improved. Moreover, by effectively utilizing the space 20, the piping support structure can be further made more compact while further improving the degree of freedom in designing the piping support structure.

<Third Embodiment>
FIG. 4 is a top view showing a pipe support structure according to a third embodiment of the present invention. Unlike the case of the first embodiment, the support 1 of this pipe support structure has a vertically laid pipe 12 passed through a space surrounded by each beam 1b. The support 1 is provided with a piping lug 10, a lug support 14, and a piping support 16 similar to those in the first embodiment. Regarding the same configuration as that of the first embodiment, the same reference numerals as those of the first embodiment may be added to the drawings to omit the description.

Further, hereinafter, in FIG. 4, the pipe axial direction X of the pipe 12 is the vertical direction of the paper surface, the direction toward the front side of the paper surface is the upward direction, and the direction toward the back side of the paper surface is the downward direction. Further, the pipe radial direction Y of the pipe 12 is the vertical direction in the figure, the direction toward the upper side in the figure is the right direction, and the direction toward the lower side in the figure is the left direction. Further, the pipe radial direction Z of the pipe 12 is the left-right direction in the figure, the direction toward the right side in the figure is the front direction, and the direction toward the left side in the figure is the back direction. Hereinafter, the description will be made on the premise of this positional relationship.

Here, in the present embodiment, spacers 22 are provided between the piping lug 10 and each lug support 14.
FIG. 5 is a plan view of the spacer 22. The spacer 22 has, for example, a rectangular plate shape in a plan view, and a semicircular or arcuate notch 22a along the outer peripheral surface 12a of the pipe 12 is formed on one end side thereof.

FIG. 6 is a partial cross-sectional view of the support 1 as viewed from the CC direction of FIG. The spacer 22 is joined to the support surface 14a of the lug support 14, and faces the pressure receiving surface 10a of the piping lug 10 with an axial gap G1. In the case shown in FIG. 6, due to the structure of the support 1 shown in FIG. 4, the ratio of the diameter of the pipe lug 10 to the diameter of the pipe 12 is smaller than that shown in FIG. 2 of the first embodiment. In this case, the area ratio of the contact region 14c to the support surface 14a of the lug support 14 becomes so small that it does not reach 30%. With this, it is not possible to secure a large pressure receiving area in the lag support 14.

However, by joining the spacer 22 to the lug support 14 and allowing the spacer 22 to function as a complementary portion of the lug support 14, it can be treated as if the support surface 14a is formed on the spacer 22. Therefore, while substantially securing the gaps G1 and G2, the area ratio of the contact region 14c is preferably 30% or more, more preferably 50% or more and 70% or less, so that the pressure receiving area in the lag support 14 can be increased. It is possible to secure a large area.

FIG. 7 is a partial cross-sectional view of the support 1 as viewed from the DD direction of FIG. In the case shown in FIG. 7, due to the structure of the support 1 shown in FIG. 4, the lug support 14 must be arranged close to the pipe 12. In this case, when the pipe 12 is displaced, the corner portion 14d of the lug support 14 may come into contact with the root portion 10d of the pipe lug 10 reaching the outer peripheral surface 12a of the pipe 12, and it is necessary to take measures.

Therefore, by joining the spacer 22 to the lug support 14 and allowing the spacer 22 to function as a complementary portion of the lug support 14, it is possible to avoid contact of the corner portion 14d with the root portion 10d. Further, in the case shown in FIG. 7, by adjusting the size of the spacer 22, the area ratio of the contact region 14c is preferably 30% or more, more preferably 50% or more while substantially securing the gap G1. Moreover, by setting it to 70% or less, it is possible to secure a large pressure receiving area in the lag support 14.

As described above, the pipe support structure of the present embodiment restrains the pipe 12 only when necessary while improving the degree of freedom in design, workability and reliability as in the case of the first and second embodiments. Priority can be given to the protection of the pipe 12. In particular, in the case of the present embodiment, it is difficult to secure the pressure receiving area in the lug support 14 due to the structure of the pipe support structure due to the provision of the spacer 22, or the lug support 14 is close to the pipe 12. However, by adjusting with the spacer 22, it is possible to secure a large pressure receiving area in the lag support 14 when the pipe 12 is displaced.

In addition, when the lug support 14 is close to the pipe 12, it is possible to prevent the corner portion 14d from coming into contact with the root portion 10d when the pipe 12 is displaced. Therefore, the pipe 12 can be effectively protected while increasing the degree of freedom in designing the pipe support structure.
Further, the notch 22a of the spacer 22 along the outer peripheral surface 12a of the pipe 12 can prevent the pipe 12 itself from coming into contact with the lug support 14 when the pipe 12 is displaced. Therefore, the pipe 12 can be protected more effectively.

Although the description of the embodiment of the present invention is completed above, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the present invention.

For example, the structure of the pipe support structure described in the above embodiment, and thus the structure of the support body 1, can be changed without departing from the gist of the present invention, and is not strictly limited to the structure described.
Specifically, as shown in FIG. 8, one lug support 14 continuous in the pipe axial direction X may be provided between adjacent pipe lugs 10.

In this case, the support surfaces 14a located at both ends of one lug support 14 face the pressure receiving surfaces 10a of the adjacent piping lugs 10. As a result, as in the case of the above embodiment, the pipe 12 can be restrained only when necessary to give priority to the protection of the pipe 12, and the number of lug supports 14 with respect to the number of pipe lugs 10 can be reduced. Therefore, it is possible to reduce the number of constituent members of the support 1 while improving the design flexibility and workability of the pipe support structure, and it is possible to reduce the cost related to the pipe support structure.

Further, in the above embodiment, the notch 22a of the spacer 22 is formed in a semicircular shape or an arc shape. However, the notch 22a may have a shape along the outer peripheral surface 12a of the pipe 12, and is not limited to a semicircular shape or an arc shape.
Further, in the above embodiment, the pipe lug 10 has a disk shape protruding from the outer peripheral surface 12a of the pipe 12 along the circumferential direction in the pipe radial direction Y. However, the pipe lug 10 is limited to a disk shape as long as it protrudes from the outer peripheral surface 12a of the pipe 12 in the pipe radial direction Y along the circumferential direction and has a similar shape to the cross-sectional shape of the pipe 12. It's not something.

Further, in the above embodiment, the support 1 is provided with four sets of a pair of lug supports 14 and four sets of a pair of piping supports 16. However, the number of pairs of the lug supports 14 and the piping supports 16 is not limited to four, and two sets are spaced apart in the circumferential direction of the piping 12 according to the structure of the support 1. The above may be provided.

Further, in the above embodiment, a disk-shaped pipe lug 10 and a cross-shaped pipe lug 18 are formed on the pipe 12. However, if it is a pipe lug that has a plate shape protruding from the outer peripheral surface 12a of the pipe 12 in a direction orthogonal to the pipe axis direction X along the circumferential direction and a pressure receiving surface facing the pipe axis direction X is formed. It is not limited to the above shape. For example, depending on the structure of the support 1, the piping lug may be in the shape of a ring plate (ring plate shape) including an elliptical plate shape other than the disk shape, two places other than the cross shape, three places, or A radiation plate shape may be formed in which five or more points are projected in a direction orthogonal to the pipe axis direction X.

Further, as described in the above embodiment, the support 1 can be applied to support both the horizontal pipe and the vertical pipe, and when the pipe 4 and the structure 2 do not exist, the support 1 is used as a basis. It may be installed directly on the wall 6, or may not be supported by the wall 8 if there is no structural problem.
Further, in the above embodiment, the pipe lug 10 is integrally formed with the pipe 12 by forging, but may be joined by welding. Even in this case, the structure of the support 1 described above makes it possible to construct a pipe support structure in which the pipe 12 is restrained only when necessary and the protection of the pipe 12 is prioritized while at least improving the degree of freedom in design. is there.
