Description

  The present invention relates to a support fixing structure for piping. More specifically, the present invention relates to a structure for supporting and fixing a pipe installed in a building or the like.

  In buildings such as middle- and high-rise apartment buildings and office buildings, for example, vertical pipes extending in the vertical direction of the building are provided as pipes for water supply or hot water supply.

  Such vertical piping is provided in the interior of a pipe shaft, which is a piping installation space provided in a building, as follows.

  That is, a through hole is formed in a partition wall such as a floor slab that is a partition wall that partitions the upper floor and lower floor of a building, and a pipe member is inserted into the through hole. In order to prevent the pipe member from being displaced in the radial direction or the like in the through hole, a non-combustible material such as mortar is formed in a gap formed between the through hole and the pipe member as a pipe fixing portion. Embed the filler.

  Furthermore, in order to suppress the displacement of the pipe member in the axial direction due to thermal expansion and contraction due to temperature change in the pipe shaft, the pipe member is supported and fixed to the partition wall using another pipe fixing portion. For example, the other pipe fixing portion may be a band member attached to the pipe member and an anchor bolt or a concrete pin embedded in the partition wall connected to each other.

  And when such vertical piping is old and renewed, the partition wall around the pipe member is hung with a rock drill or the like, or cut with a cutting machine such as a core drill, and the pipe member is removed from the partition wall. It has been removed. In this case, renewal vertical piping is applied to the cutting hole newly formed in the partition wall by removing the pipe member and larger than the through hole in the same manner as described above. Become.

  However, since the above-mentioned means generate a lot of noise and dust, there is a risk of causing inconvenience such as discomfort to residents and the like, so an updating means that does not generate noise and dust is desired.

  Therefore, a jack-up method has been proposed in which a pipe member is pulled out from a partition wall using a jack (see, for example, Patent Document 1).

JP 2006-200656 A

  However, in the jack-up method described above, an extraction hole having the same diameter as the tube member, which is a trace of the tube member being pulled out, is formed in the portion of the partition wall filled with mortar. There arises a problem that the pipe member has to have a smaller diameter than the above-described extraction hole. Moreover, since it is difficult to obtain a sufficient gap for filling the mortar between the renewal pipe member and the extraction hole, there arises a problem that the pipe member cannot be fixed with the mortar.

In order to solve the above-described problems, the present invention provides a pipe for supporting and fixing a pipe member to a partition wall using a pipe fixing portion in a state in which the resin pipe member is inserted into a through hole formed in the partition wall. In the support fixing structure, a pair of sandwiching members as the pipe fixing portion are attached to the outer periphery of the tube member so as to be integrated with the tube member, and the partition wall is sandwiched between the pair of sandwiching members. A tubular connecting member that forms a direct wall fixing portion that can directly support and fix the tube member to the partition wall and can be fitted to the outer periphery of the tube member as the pinching member, or the tube member A receiving portion that can be inserted and connected to the tube member, and has an electrothermal fusion mechanism that can be electrically fused to the pipe member. By electrothermal fusion using the attachment mechanism, integrated with the outer periphery of the tube member, Characterized in that than the outer shape of the sintered member or socket portions is engaged around the through-hole formed in the small diameter.

According to the present invention, the following effects can be obtained by the above configuration. That is, the direct wall fixing portion formed by integrating a pair of sandwiching members on the outer periphery of the tube member firmly fixes the tube member and the partition wall directly and suppresses displacement of the tube member in the axial direction or the like. . Since the pinching member that can be integrated with the outer periphery of the pipe member is used to fix the pipe member to the partition wall, it is possible to use a pipe member having a diameter substantially equal to or smaller than that of the through hole. At the same time, it is possible to eliminate the need for filling and fixing between the through hole and the pipe member with a filler such as mortar. Therefore, even if it is a case where it is renewed with a jack-up construction method as well as a new construction, it can be constructed without any trouble.
In addition, by using a connecting member or a receiving part having an electrothermal fusion mechanism as a sandwiching member, the outer shape of the connecting member or the receiving part in the partition wall without using a special pipe fixing part. It can be supported and fixed so as to be locked around a through-hole formed to have a smaller diameter. In addition, since the connecting member and the receiving portion having the electric heat fusion mechanism have a sufficient track record of use, they can be reliably integrated with the pipe member and directly used as the wall fixing portion. In addition, since the connecting member and the receiving portion having the electric heat fusion mechanism can be finely adjusted at the site, the direct wall fixing portion should be more tightly clamped and fixed to the partition wall. it can.

It is a side view which shows the pipe | tube insertion process which inserts and arrange | positions a pipe member to the through-hole of a partition. It is a side view which shows the 1st integration process of integrating one pinching member with a pipe member. It is a side view which shows the 2nd member fitting process which fits the other pinching member to a pipe member, and the 2nd member fitting process integrated. It is a side view which shows the state which provided the wall fixing part directly only with respect to the partition of the uppermost floor of a building, and the partition of the lowest floor.

  In order to solve the above-described problems, the present invention mainly enables installation of a pipe member having substantially the same diameter as the through-hole and fills a gap between the through-hole and the pipe member. The pipe member can be fixed without being filled with a material.

  Hereinafter, embodiments embodying the present invention will be described together with illustrated examples.

  1 to 5 show an embodiment of the present invention.

  <Configuration> First, the configuration will be described.

  As shown in the side view of FIG. 4, the support and fixing structure of the water supply vertical pipe according to this embodiment is such that the pipe member 3 is inserted into the through-hole 2 formed in the partition wall 1. Is fixed to the partition wall 1 by using the pipe fixing portion 4.

  In addition to the basic configuration as described above, the present embodiment has the following configuration.

(Configuration 1) A pair of sandwiching members 5 as the pipe fixing portions 4 are attached to the outer periphery of the pipe member 3 so as to be integrated with the pipe member 3. Then, in the pair of clamping wear member 5, by clamped on SL septum 1, to form a supported directly securable directly wall fixing portion 11 relative to the tubular member 3 the partition wall 1.

  Here, the pair of sandwiching members 5 are arranged with the same interval as the thickness of the partition wall 1. The pinching member 5 can be attached to and detached from the outer periphery of the tube member 3 and can finally be integrated with the tube member 3. The pinching member 5 extends outward from the tube member 3 and can be locked to the partition wall 1. The pinching member 5 can be, for example, a flange-like member extending in the circumferential direction or a radial member extending in the radial direction with respect to the tube member 3.

  (Configuration 2) The pinching member 5 is attached to the pipe member 3 by the steps shown in order in FIGS.

  That is, first, one pinching member 5 is fitted on the pipe member 3 in advance in the first member fitting step shown in FIG. One clamping member 5 is installed in the vicinity of a portion located in the through hole 2 of the tube member 3.

  Next, the tube member 3 is inserted into the through hole 2 of the partition wall 1 in the tube insertion step shown in FIG. The tube member 3 is inserted into the through hole 2 from the end portion on the side where the one sandwiching member 5 is fitted. In FIG. 2, reference numeral 3 a denotes a (lower) end portion of the existing pipe member 3.

  Next, in the first integration step shown in FIG. 3, one clamping member 5 is brought into contact with one surface of the partition wall 1 and integrated with the pipe member 3. The method of integration will be described later.

  Next, in the second member fitting step shown in FIG. 4, the other pinching member 5 is externally fitted to the pipe member 3 from the other surface side of the partition wall 1. The other pinching member 5 is installed in the vicinity of a portion located in the through hole 2 of the pipe member 3. Further, in the second integration step, the other pinching member 5 is brought into contact with the other surface of the partition wall 1 and integrated with the pipe member 3. Thereby, the partition wall 1 is sandwiched between the pair of sandwiching members 5. The above is the first construction method (construction method A).

  Alternatively, although not particularly illustrated, after the tube member 3 is first inserted through the through-hole 2 of the partition wall 1 by the above-described tube insertion step, the tube member 3 is formed by the first and second member fitting steps described above. The pipe members 3 are fitted on the opposite sides of the partition wall 1 from the both sides of the partition wall 1 so that each of the sandwich member members 5 is in contact with both surfaces of the partition wall 1 in the first and second integration steps. It is also possible to sandwich the partition wall 1 with a pair of sandwiching members 5 (Method B). However, in the case of the pipe member 3 of FIGS. 1 to 4, the construction method B cannot be adopted because it has a receiving portion 6 b described later.

  (Configuration 3) At this time, as the above-described pinching member 5, a cylindrical connecting member 6a that can be fitted to the outer periphery of the tube member 3, or a receiving portion 6b that can be inserted and connected to the end of the tube member 3. And what has the electric heat fusion | fusion mechanism 7 which can be electrically heat-fused with respect to the pipe member 3 is used, respectively. Then, the connecting member 6a (electric heat-welding connecting member) or the receiving portion 6b (electric heat-welding receiving portion) is attached to the outer periphery of the tube member 3 by electrothermal fusion using the electrothermal fusing mechanism 7. It integrates, ie, the interface of the pipe member 3 and the pinching member 5 is fusion-bonded.

  The electrothermal fusion is performed by connecting an external power supply device 9 to the connecting member 6a as the pinching member 5 or the terminal portion 8 provided in the receiving port portion 6b and energizing it.

  Here, the tube member 3, the connecting member 6a, and the receiving portion 6b are preferably made of resin such as polyethylene in order to be suitable for electrothermal fusion.

  If necessary, the tube member 3 can be temporarily held and fixed using an external holding member (not shown) during the electric heat fusion. This external holding member can be removed after electrothermal fusing.

  The “connecting member 6a” is a socket member or a joint member that can connect the two pipe members 3 on the same straight line. The connecting member 6a has a pair of receptacles that can insert and fix the ends of the two pipe members 3 at both ends of a short cylindrical main body. The main body of the connecting member 6 a has an inner diameter equal to the outer diameter of the pipe member 3 and an outer diameter larger than the inner diameter of the through hole 2. In many cases, a stopper for restricting the position of the end of the inserted tube member 3 is provided inside the connecting member 6a. In this case, the connecting member can be removed by deleting the stopper. 6a can be freely arranged in the middle part of the pipe member 3.

  The “receiving port 6 b” is provided integrally with the end of the pipe member 3. The receiving portion 6 b has an inner diameter equal to the outer diameter of the pipe member 3 and an outer diameter larger than the inner diameter of the through hole 2. In this case, it is assumed that the receiving port 6 b serving as the pinching member 5 is attached to the end of the pipe member 3 different from the pipe member 3 inserted through the through hole 2.

  The “electric heat fusion mechanism 7” includes a heating coil (not shown) embedded in the coupling member 6a and the receiving port 6b, and the terminal portion 8 connected to both ends of the heating coil. ing.

  In addition, the above-described tube member 3 may have the receiving portion 6b at the end portion or may not have the receiving portion 6b.

  In this case, a pipe fixing part 4 is connected to a pipe member 3 having a receiving part 6b at the upper end and adjusted to a length approximately equal to or slightly longer than the distance between the upper and lower partition walls 1. Since the member 6a and the receiving port 6b attached to the end of another pipe member 3 are used, the connecting member 6a is fitted to the pipe member 3 from the lower end side as shown in FIG. As shown in FIG. 2, the pipe member 3 is inserted into the through hole 2 from the lower end side, and as shown in FIG. 4, the pipe member 3 of another pipe member 3 is inserted into the pipe member 3 from the lower end side. Is adopted. Moreover, the pipe member 3 is installed from the upper side to the lower side. In order to bring the receiving portion 6b into contact with and locked to the lower surface of the partition wall 1, if necessary, the lower end portion of the tube member 3 protruding to the lower surface side of the partition wall 1 is partially cut off. Moreover, the fitting depth of the receiving part 6b with respect to the lower end part of the pipe member 3 can also be adjusted. In addition, for example, in the case of using a pipe member 3 having a receiving portion 6b at the lower end and adjusted to a dimension that is approximately the same as or slightly longer than the distance between the upper and lower partition walls 1, for example, The above procedure should be performed in the opposite direction.

  On the other hand, when the pipe member 3 having the receiving portion 6b at the upper end portion or the lower end portion and shorter than the distance between the upper and lower partition walls 1 is used, the receiving portion 6b is accurately positioned with respect to the partition wall 1. Since it becomes difficult to match, it is possible to use another connecting member 6a instead of the receiving port 6b. That is, the method A is performed using the two connecting members 6a.

  Moreover, when using the pipe member 3 which does not have the opening part 6b in both an upper end part and a lower end part, it is made to use the two connection members 6a. In this case, since there is no obstructing opening 6b, after the pipe member 3 is first inserted into the through hole 2 in addition to the above-described method A, the connecting member 6a is fitted from both ends of the pipe member 3. The combined construction method B can also be adopted.

  (Configuration 4) As shown in FIG. 3, by spreading a thermally expandable fireproof sheet 12 around the outer periphery of the portion located in the through hole 2 of the pipe member 3, the partition wall 1 becomes a fireproof partition wall 13 and spreads fire. To prevent.

  Here, the heat-expandable fireproof sheet 12 literally expands with the heat of the fire when a fire occurs, thereby closing the softened tube member 3 and blocking the flame and smoke. It is. For the heat-expandable fireproof sheet 12, materials such as Fibrok manufactured by Sekisui Chemical Co., Ltd. can be used. The heat-expandable fireproof sheet 12 may be attached to the outer periphery of the pipe member 3 in advance, or may be attached to the outer periphery of the pipe member 3 during construction.

  (Configuration 5) As shown in FIG. 4, the partition wall 1 is a partition wall 15 that partitions the upper floor and the lower floor of the building 14. Moreover, the said pipe member 3 shall comprise the vertical piping 16 extended in the up-down direction of the building 14. As shown in FIG.

Here, the “building 14” is, for example, a mid-to-high-rise apartment house or office building. The “partition wall 15” is a horizontal floor slab of the building 14 or the like.
The “vertical pipe 16” is a pipe for water supply or hot water supply, for example. Such a vertical pipe 16 is usually provided on a pipe shaft which is a pipe installation space provided in a building.

  A vertical branch pipe (not shown) is usually connected to the vertical pipe 16 for water supply or hot water supply via a branch joint 17. The branch joint 17 described above may be attached in advance to the pipe member 3 before the installation of the vertical pipe 16 or may be attached to the pipe member 3 after the installation of the vertical pipe 16. In this case, the branch joint 17 has an electric heat fusion mechanism 7 capable of electric heat fusion (branch joint for electric heat fusion). The vertical pipe 16 as the pipe member 3 is a short pipe member connected by a branch joint 17.

  Although not particularly illustrated, the partition wall 1 may be a partition wall such as a vertical wall that partitions adjacent spaces on the same floor of the building 14, and the pipe member 3 may be a horizontal pipe extending in the horizontal direction.

  (Configuration 6) As shown in FIG. 5, the direct wall fixing portion 11 as the pipe fixing portion 4 described above is provided only for the partition wall 1a on the uppermost floor and the partition wall 1b on the lowermost floor of the building 14. To.

  Here, the part of the intermediate partition 1c other than the partition 1a on the uppermost floor and the partition 1b on the lowermost floor is the non-fixed portion 18 where the wall fixing portion 11 is not directly provided.
