Description

  The present invention relates to a sleeve structure for penetrating equipment piping through an outer wall of a building.

  Patent Document 1 below proposes a structure of a sleeve including a through hole formed in a wall portion, a wall portion penetrating member provided in the through hole, and a pipe penetrating the wall portion penetrating member. The wall portion penetrating member used in this structure has a main body that holds the pipe and a water stop portion that is formed outside the main body.

  The water-stop portion is an elastic member disposed outside the wall portion between the outer peripheral surface of the main body and the inner peripheral surface of the through hole, and a water-swellable nonwoven fabric disposed inside the wall portion with respect to the elastic member It is comprised including. The elastic member is elastically deformed between the main body and the through hole, thereby increasing the water stoppage of the through hole. Moreover, the water-expandable nonwoven fabric expands due to the intrusion of rainwater and increases the water-stopping property of the through hole.

  However, in the structure of Patent Document 1, when the inner surface of the through hole is uneven, it is difficult for the elastic member to prevent rainwater from entering the through hole. There was a problem that the deterioration of the outer wall was promoted by the moisture that entered from there.

  The present invention has been devised in view of the actual situation as described above, and is based on the fact that a concave portion recessed from the outer surface of the outer wall between the sleeve tube and the through-hole is filled with a sealing material, and the water-stopping property of the through-hole. The main object is to provide a sleeve structure that can improve the height of the sleeve.

  The present invention relates to a sleeve structure for allowing equipment piping to pass through an outer wall of a building, the through-hole communicating between the outer surface of the outer wall on the outdoor side and the inner surface of the outer wall on the indoor side, the through-hole And a sleeve tube that guides the equipment piping, and is disposed in a compressed state between the sleeve tube and the through hole at a position that is further on the inner surface side than the outer surface. It includes an elastic member that forms a recess recessed from the outer surface between the tube and the through hole, and a sealing material that fills the recess.

  In the sleeve structure according to the present invention, the elastic member is preferably made of a watertight material.

  In the sleeve structure according to the present invention, it is desirable that the sealing material is in contact with the elastic member in the axial direction of the sleeve tube.

  The structure of the sleeve of the present invention includes a through hole that communicates between an outer surface of the outer wall on the outdoor side and an inner surface of the outer wall on the indoor side, and a sleeve pipe that is disposed in the through hole and guides the equipment piping. It is out. Furthermore, the structure of the sleeve is arranged in a compressed state between the sleeve tube and the through hole at a position reserved on the inner surface side with respect to the outer surface, thereby forming a recess recessed from the outer surface between the sleeve tube and the through hole. An elastic member to be formed and a sealing material filled in the recess are included.

  In such a sleeve structure, since the elastic member is disposed in a compressed state between the sleeve tube and the through hole, the sleeve tube can be stably held in the through hole. Further, the elastic member can improve the airtightness in the gap between the sleeve tube and the through hole, and can prevent the heat insulation of the outer wall from being lowered. Furthermore, the elastic member can be used as a backup material for the sealing material, and can improve the workability. Moreover, when an elastic member is formed from the material which does not adhere | attach with a sealing material, since a bond breaker becomes unnecessary, workability | operativity can be improved further.

  Even if the inner surface of the through hole is uneven, the sealing material can be disposed without a gap between the inner peripheral surface of the through hole and the outer peripheral surface of the sleeve tube in the concave portion recessed from the outer surface of the outer wall. For this reason, the sealing material can reliably prevent rainwater from entering the through hole. Therefore, the structure of the sleeve of the present invention can increase the water-stopping property of the through hole and can suppress the deterioration of the outer wall.

  FIG. 4 is a perspective view of the sleeve tube 12 and the elastic member 13 of the present embodiment. As shown in FIGS. 2 and 4, the sleeve tube 12 is formed in a cylindrical shape having a hole portion 16 and is disposed in the through hole 11 of the outer wall 2. Equipment piping 17 (shown in FIG. 1) is disposed in the hole 16 of the sleeve tube 12. The axial length L2 of the sleeve tube 12 is set to be substantially the same as the distance L1 between the outer surface 2o and the inner surface 2i of the outer wall 2. Thereby, the sleeve pipe | tube 12 can guide the installation piping 17 arrange | positioned in the hole 16 in the through-hole 11 from indoor side Si to the outdoor side So.

  As shown in FIG. 2, in the present embodiment, the one end 12 o on the outdoor side So side of the sleeve tube 12 is disposed at a position that is less on the inner surface 2 i side than the outer surface 2 o of the outer wall 2. Further, the other end 12 i on the indoor side Si side of the sleeve tube 12 is disposed at a position that is less on the outer surface 2 o side than the inner surface 2 i of the outer wall 2. Thereby, the sleeve pipe | tube 12 can prevent interference with the sleeve caps 21 and 21 arrange | positioned at both the one end 12o and the other end 12i.

  As long as the outer diameter D2 of the sleeve tube 12 is smaller than the inner diameters D1a, D1b, and D1c of the through-hole 11, it can be appropriately set according to the size of the equipment pipe 17. The outer diameter D2 of the sleeve tube 12 of this embodiment is set to about 65 mm to 85 mm, for example. The sleeve tube 12 can be formed of, for example, a synthetic resin such as vinyl chloride or a metal such as stainless steel.

  The sleeve caps 21 and 21 include a base portion 22 fixed to the sleeve tube 12 and a lid portion 23 detachably fixed to the base portion 22 in the same manner as the conventional sleeve cap.

  The base portion 22 includes a cylindrical portion 22a fixed to the inner surface of the sleeve tube 12, and a flange portion 22b extending in a flange shape at the end portion of the cylindrical portion 22a. A sealing material (not shown) is filled between the outer surface of the cylindrical portion 22a and the inner surface of the sleeve tube 12. Such sleeve caps 21 and 21 can close the openings provided at the one end 12o and the other end 12i of the sleeve pipe 12 in an unused state where the equipment pipe 17 is not disposed on the sleeve pipe 12.

  As shown in FIGS. 2 and 4, the elastic member 13 is formed in a substantially cylindrical shape continuous in the circumferential direction of the sleeve tube 12. The elastic member 13 of this embodiment is fixed to the outer peripheral surface of the sleeve tube 12 in advance. The length L3 of the elastic member 13 in the axial direction is set to be smaller than the length L2 of the sleeve tube 12 in the axial direction. The length L3 of this embodiment is set to about 15% to 40% of the length L2 of the sleeve tube 12, for example.

  The outer diameter D3 of the elastic member 13 is the inner diameter of the through-hole 11 (the inner diameter D1a of the hole 11a of the exterior material 4, the inner diameter D1b of the hole 11b of the interior material 5, and the inner diameter of the hole 11c of the heat insulating material 6 (illustrated). (Omitted) is set larger than

  Thereby, the elastic member 13 can be elastically deformed between the sleeve tube 12 and the through-hole 11, and the sleeve tube 12 can be stably held in the through-hole 11 by utilizing the restoring force. it can. Moreover, since the elastic member 13 can improve airtightness in the clearance gap between the sleeve pipe | tube 12 and the through-hole 11, it can prevent the heat insulation fall of the outer wall 2. FIG. The elastic member 13 of the present embodiment is greatly compressed and deformed between the exterior material 4 harder than the heat insulating material 6 and the sleeve tube 12.

  The outer diameter D3 of the elastic member 13 can be appropriately set as long as it is larger than the inner diameter of the through hole 11 (the inner diameter D1a of the hole 11a of the exterior material 4). The outer diameter D3 of the elastic member 13 of the present embodiment is desirably set to about 105% to 120% of the inner diameter D1a of the hole 11a, for example.

  As shown in FIG. 4, the elastic member 13 is fixed to the sleeve tube 12 at a position withdrawn from the one end 12 o to the other end 12 i side. Therefore, as shown in FIG. 3, the elastic member 13 is positioned at the inner surface 2 i (shown in FIG. 2) side of the outer wall 2 than the outer surface 2 o of the outer wall 2 in a state where the sleeve tube 12 is disposed in the through hole 11. It is fixed with. Thereby, the elastic member 13 can form the recessed part 26 recessed from the outer surface 2o between the sleeve pipe | tube 12 and the through-hole 11. FIG. The recess 26 of the present embodiment is formed in a ring shape that is continuous in the circumferential direction of the sleeve tube 12 on the outer surface 2 o of the outer wall 2.

  As the elastic member 13, any elastic member can be used as long as it can be compressed and deformed between the sleeve tube 12 and the through hole 11. The elastic member 13 is preferably formed of a watertight material. Such an elastic member 13 can prevent rainwater from entering the hole 11 a and the heat insulating material 6 of the exterior material 4, and can improve the water-stopping property of the through-hole 11. In addition, as a watertight material which forms the elastic member 13, a urethane type foam watertight material, EPDM foam watertight material, or a water-swellable watertight material etc. are employable, for example. In the present embodiment, a super sheet H3 manufactured by Nihon Hojo Co., Ltd. is used.

  As shown in FIG. 3, it is desirable that the elastic member 13 is fixed to a position where at least a part of the elastic member 13 overlaps the hole 11 a of the exterior material 4 in the axial direction of the sleeve tube 12. Thereby, since the elastic member 13 can be effectively compressively deformed between the exterior material 4 harder than the heat insulating material 6 and the sleeve tube 12, the sleeve tube 12 can be stably held. . The overlapping length L5 between the elastic member 13 and the hole 11a of the exterior material 4 is preferably about 10% to 100% of the axial length L3 of the elastic member 13.

  As the elastic member 13 of the present embodiment, the one that has been processed into a cylindrical shape in advance prior to being fixed to the sleeve tube 12 is illustrated, but is not limited thereto. FIG. 5 is a perspective view showing a sleeve tube 12 and an elastic member 13 according to another embodiment of the present invention.

  The elastic member 13 of this embodiment is formed in a cylindrical shape by winding a sheet-like elastic member 13 s around the sleeve tube 12. Such an elastic member 13 can flexibly set the outer diameter D3 (shown in FIG. 4) of the elastic member 13 according to the inner diameter of the through hole 11 (the inner diameter D1a of the hole 11a of the exterior material 4) or the like. Therefore, workability can be improved.

  As shown in FIG. 3, the sealing material 14 is filled in a recess 26 that is recessed from the outer surface 2 o between the sleeve tube 12 and the through hole 11.

  For example, the sealing material 14 before curing is flexible between the concave and convex portions, even if large irregularities that the elastic member 13 cannot follow are formed on the inner surface of the through hole 11 (the hole portion 11a of the exterior material 4). I can get in. For this reason, the sealing material 14 can be disposed between the inner peripheral surface of the through hole 11 and the outer peripheral surface of the sleeve tube 12 without a gap. Thereby, the sealing material 14 can reliably prevent rainwater from entering the through hole 11 (the gap between the sleeve tube 12 and the through hole 11) on the outer surface 2 o side of the outer wall 2. Therefore, the structure of the sleeve of the present invention can surely increase the water-stopping property of the through hole 11 and can suppress the deterioration of the outer wall 2.

  In the axial direction of the sleeve tube 12, the depth (the length of the recess 26) L4 of the sealing material 14 can be set as appropriate. In order to reliably prevent rainwater from entering the gap between the sleeve tube 12 and the through-hole 11, the depth L4 of the sealing material 14 is set to 50% to 80% of the thickness W1 of the exterior material 4. Is desirable. Moreover, as the sealing material 14, for example, an architectural sealing material, an asphalt sealing, or a polymer cement sealing can be employed.

  The sealing material 14 is preferably in contact with the elastic member 13 in the axial direction of the sleeve tube 12. Thereby, the sealing material 14 can prevent rainwater from entering the gap between the sleeve tube 12 and the through hole 11 together with the elastic member 13. Further, the elastic member 13 can be used as a backup material for preventing the sealing material 14 from being filled more than necessary into the indoor side Si, and can improve workability. The elastic member 13 may be formed of a material that does not adhere to the sealing material 14. Thereby, since the bond breaker (illustration omitted) which prevents adhesion | attachment with the elastic member 13 and the sealing material 14 becomes unnecessary, workability | operativity can further be improved.

Next, an example of a construction method of the sleeve structure will be described.
In the construction method of this embodiment, first, the through-hole 11 which connects between the outer surface 2o and the inner surface 2i is provided in the outer wall 2 of a building (process S1). FIG. 6 is a cross-sectional view illustrating step S1. In step S <b> 1, first, holes 11 a and 11 b having substantially circular shapes in a front view are formed in both the exterior material 4 and the interior material 5. Next, a cylindrical hole portion 11 c that communicates between the hole portion 11 a of the exterior material 4 and the hole portion 11 b of the interior material 5 is formed in the heat insulating material 6. Thereby, in process S1, the through-hole 11 which connects between the outer surface 2o and the inner surface 2i can be formed. The dimensions and the like of the through hole 11 are as described above.

  Next, the sleeve tube 12 (shown in FIG. 4) to which the elastic member 13 is fixed is disposed in the through hole 11 (step S2). FIG. 7 is a cross-sectional view illustrating step S2. In step S2, first, the sleeve tube 12 is inserted into the hole 11a of the exterior material 4 from the other end 12i. As described above, the outer diameter D3 of the elastic member 13 is set to be larger than the inner diameter D1a of the hole 11a of the exterior material 4. For this reason, the elastic member 13 is screwed into the hole 11a of the exterior material 4 while being compressed and deformed radially inward. Thereby, in process S2, the elastic member 13 can be arrange | positioned in the compression state between the sleeve pipe | tube 12 and the through-hole 11 (hole 11a of the exterior material 4).

  The elastic member 13 is fixed at a position reserved on the inner surface 2 i side with respect to the outer surface 2 o of the outer wall 2 in a state where the sleeve tube 12 is disposed in the through hole 11. For this reason, in step S <b> 2, a recess 26 that is recessed from the outer surface 2 o can be formed between the sleeve tube 12 and the through hole 11.

  Next, the sealing material 14 is filled in the recess 26 (step S3). FIG. 8 is a cross-sectional view illustrating step S3. In step S3, for example, the sealing material 14 is filled into the recess 26 using a caulking gun or the like. In this embodiment, the sealing material 14 is filled from the outer surface 2o to the elastic member 13 without a gap. Thereby, since the elastic member 13 can be used as a backup material which prevents the sealing material 14 from filling the indoor side Si more than necessary, workability can be improved. Then, after the sealing material 14 is cured or during the curing of the sealing material 14, the next step S4 is performed.

  Next, sleeve caps 21 and 21 (shown in FIG. 9) are attached to the one end 12o and the other end 12i of the sleeve tube 12 (step S4). FIG. 9 is a cross-sectional view illustrating step S4. In step S4, first, a sealing material (not shown) is applied to the outer peripheral surface of the cylindrical portion 22a of each sleeve cap 21, 21. In the present embodiment, the sealing material is applied in a rod shape along the circumferential direction of the cylindrical portion 22a. Next, the cylindrical portion 22 a of each sleeve cap 21, 21 is inserted into the sleeve tube 12. At this time, the flange portion 22 b of each sleeve cap 21, 21 is brought into contact with the outer surface 2 o or the inner surface 2 i of the outer wall 2. The sleeve caps 21 and 21 are fixed to the sleeve tube 12 by the curing of the sealing material.

  It is desirable that the sleeve caps 21 and 21 are temporarily fixed to the outer wall 2 using, for example, a masking tape until the sealing material is cured. As a result, the sleeve caps 21 and 21 can be prevented from falling off the sleeve tube 12.

  Thus, the structure of the sleeve of the present embodiment can be formed by sequentially performing the above-described steps S1 to S4. As shown in FIG. 1, when the equipment pipe 17 is guided to the sleeve pipe 12, the lid portions 23 and 23 of the sleeve caps 21 and 21 are removed. Thereby, the structure of the sleeve allows the equipment pipe 17 to penetrate the outer wall 2 through the base portions 22 and 22 of the sleeve caps 21 and 21 and the sleeve tube 12.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
