Description

  The present invention is attached to the end of a ventilation parting material that secures the ventilation between the ventilation space between the outer wall material and the wall base and the outside, and closes the end surface of the ventilation parting material, The present invention relates to an end member used for connecting, and also relates to an outer wall structure of a building provided with the ventilation parting material and the end member.

  When the outer wall material 2 is stretched and attached to the wall base 4 of the building, a ventilation space 5 may be formed between the wall base 4 and the outer wall material 2. And by ensuring air permeability between this ventilation space 5 and the outdoors, it is possible to suppress moisture from rising between the wall base 4 and the outer wall material 2, and to prevent mold and dirt on the inner surface of the outer wall material 2 and the wall base 4. It is possible to prevent the occurrence of corrosion.

  Thus, the upper end of the ventilation space 5 formed on the back side of the outer wall member 2 is generally communicated with the back of the hut 48 as shown in FIG. 10, for example. In this case, ventilation is performed between the ventilation space 5 and the shed 48 as indicated by an arrow in FIG. 10A, and the ventilation between the ventilation space 5 and the outside is via a ventilation ridge or the like communicating with the hut 48. Secured.

  However, when the ventilation space 5 and the hut 48 are communicated in this way, there is a problem that restrictions on the construction of the building become large. Further, in order to renovate the outer wall of an existing building, when the new outer wall material 2 is attached using the existing outer wall material as the wall base 4, a ventilation space 5 is provided between the new outer wall material 2 and the wall base 4. Even if it is formed, the ventilation space 5 cannot be communicated with the cabin 48, and there is a problem that the air permeability cannot be ensured.

In this case, as indicated by an arrow a in FIG. 11A, ventilation between the ventilation space 5 and the outside can be performed through the inner opening 7, the ventilation path 8, and the outer opening 6. And the outside air can be ensured by the parting material 1 (see Patent Document 1).

  In this parting material 1, when the wind blows from the outer opening 6 into the air passage 8 in the parting material 1, rainwater also enters the air passage 8 together with the wind, but the air faces the air space 5 and opens. Since the inner opening 7 is formed at a position higher than the outer opening 6, rainwater can be prevented from entering the ventilation space 5 from the inner opening 7. Rainwater that has entered the air passage 8 from the outer opening 6 together with the wind flows back toward the outer opening 6 by the inclined surface 49 in the air passage 8 and is drained from the outer opening 6.

  Here, the parting material 1 is used by being mounted horizontally along the eaves on the girder side, and may be used by being attached obliquely along the inclination of the roof 3 under the eaves on the wall side of the gable roof. . FIG. 9 shows a state in which the parting material 1 is obliquely attached to the end wall along the inclination of the roof 3. Further, the parting material 1 is used by being connected in the longitudinal direction by a joint 37, and an end cap 52 is attached to an end portion of the parting material 1 so as to close the opening of the end face.

  Then, as shown in FIG. 7A, an end cap 52 is disposed at the end of the ventilation parting material 1, and as shown in FIG. 1B, the fitting piece 32a is an upper surface plate of the base 12 of the ventilation parting material 1. 18, the fitting piece 32 b is placed on the front surface 20 of the base 12 of the ventilation parting material 1 and the outer surface of the bulging portion 21, and the fitting piece 32 c is placed on the rear plate 20 and the partition of the base 12 of the ventilation parting material 1. The end cap 52 can be attached to the end portion of the ventilation parting material 1 by being inserted and fitted into the inner surface of the lower piece 17. Further, the end cap 52 can be fixed to the end portion of the ventilation parting material 1 by screwing a fixing tool 60 such as a screw through the fixing hole 57 into the fixing hole 23 of the partition body 17. The end plate 29 can block the opening of the end face of the ventilation parting material 1. At this time, waterproofness can be secured by bringing the end face of the ventilation parting material 1 into pressure contact with the packing 58 provided on the end cap 52. When the end cap 52 is attached to the end portion of the ventilation part 1 in this manner, the lower protrusion 19 of the edge of the outer opening 6 of the ventilation part 1 is attached to the upper end portion of the water guide piece 31 provided on the end cap 52. The lower ends of the two are in contact or close to each other. Accordingly, the water guide piece 31 is located immediately below the outer opening 6. The end cap 52 needs to be attached to the left end of the ventilation part 1 and attached to the right end. The end cap 52 is fitted to either the left or right side of the end plate 29 or the water stop piece 30. The only difference is whether to provide the piece 32, the water guide piece 31, and the packing 58, and the basic configuration is the same.

  The ventilation parting member 1 with the end cap 52 attached in this way is disposed obliquely along the inclination of the roof 3 and fixed with screws or the like through the lower part of the back plate 13 of the base 12 as shown in FIG. The ventilation parting material 1 is attached to the vertical trunk edge 46 by driving the tool 45 into the vertical trunk edge 46. Next, another ventilation parting material 1 is connected to and connected to the ventilation parting material 1 attached to the vertical trunk edge 46.

  In FIG. 5, an example of the joint 37 used in order to connect the ventilation parting material 1 is shown. The joint 37 is formed by projecting fitting pieces 32 on both sides of an end plate 29 having an outer shape substantially matching the outer shape and size of the end surface of the ventilation parting material 1. At the end of the end plate 29 on the outdoor side and at the position of the lower end, a water stop piece 30 is integrally extended obliquely downward toward the outdoor side. A water guide piece 31 that inclines obliquely downward toward the outdoor side along the lower edge protrudes. The fitting pieces 32 are provided at three positions on both sides of the end plate 29, and the fitting pieces 32 a along the upper edge of the end plate 29 are connected to the upper surface plate 18 of the base 12 of the ventilation parting material 1. The fitting piece 32b along the front edge of the end plate 29 in a parallel shape is formed in a shape parallel to the front plate 20 and the bulging portion 21 of the base 12 of the ventilation parting material 1, and the rear of the end plate 29. The fitting pieces 32 c extending from the end edge to the lower end edge are respectively formed in a shape parallel to the lower piece of the partition body 17 from the back plate 20 of the base 12 of the ventilation parting material 1. A fixing hole 57 is formed in the center of the end plate 29. In addition, packing 58, such as rubber | gum, such as EPDM, is each affixed on both surfaces of the end plate 29, The range which affixes packing 58 is shown in FIG.5 (d).

  Then, as shown in FIG. 7 (c), a joint 37 is arranged at the end portion of the ventilation part 1 on the connecting side, and the fitting provided on one surface of the end plate 29 as shown in FIG. 1 (c). The mating piece 32a is disposed on the lower surface of the upper surface plate 18 of the base 12 of the ventilation parting material 1, the fitting piece 32b is disposed on the outer surface of the front plate 20 and the bulging portion 21 of the base part 12 of the ventilation parting material 1. The joint 37 can be attached to the end portion of the ventilation parting material 1 by being inserted and fitted into the back plate 20 of the base 12 of the ventilation parting material 1 and the inner surface of the lower piece of the partition body 17. Further, the joint 37 can be fixed to the end of the ventilation parting material 1 by screwing a fixing tool 60 such as a screw through the fixing hole 57 into the fixing hole 23 of the partition member 17. The opening at the end of the parting material 1 is closed by the end plate 29. At this time, the end face of the ventilation part 1 is pressed against the packing 58 provided in the joint 37 so that the waterproof property can be secured. Further, the lower end of the lower projecting piece 19 of the edge of the outer opening 6 of the ventilation parting material 1 is in contact with or close to the upper end of the water guide piece 31 provided in the joint 37. Accordingly, the water guide piece 31 is located immediately below the outer opening 6. If the water guide pieces 31 are provided on both sides of the water stop piece 30 as in the embodiment of FIG. 5, even when the ventilation parting material 1 that is inclined to the left is connected, it is inclined to the right. The same joint 37 can be shared when connecting the ventilation parting material 1 to be connected.

  After the joint 37 is attached to the end portion of the ventilation part 1 on the side to be connected in this way, the end part 52 of the ventilation part 1 attached to the vertical trunk edge 46 as described above is attached to the end part on which the end cap 52 is not attached. The joint 37 is connected as indicated by the arrow in FIG. The joint 37 can be connected by inserting and fitting the fitting piece 32 on the projecting side of the joint 37 into the end portion of the ventilation parting material 1 in the same manner as described above. In this way, the pair of ventilation parting materials 1 can be connected in a straight line using the joint 37. At this time, as shown in FIG. The waterproof tape 62 is stuck on 46, and the connection part is waterproofed.

  After the ventilation parting material 1 is attached to both sides sandwiching the top of the wife wall as described above, the apex cover 50 is attached and connected between the upper end parts of the upper ventilation parting material 1. An example of the vertex cover 50 is shown in FIG. The apex cover 50 is formed in a U-shaped cross-section opening on the back side by bending the upper piece 65 and the lower piece 66 at the upper end and lower end of the front piece 64, and the rear end of the lower piece 66. A fixed piece 67 is provided to hang downward. Further, notches 70 are formed by notching from the lower end of the front piece 64 to the front end of the lower piece 65 at both left and right ends of the vertex cover 50. Further, a cut line 68 is cut out from the front piece 64 to the lower piece 66 and the fixed piece 67 at the center of the left and right sides of the ventilation parting member 1 except for the upper piece 65.

  Then, as shown in FIG. 8 (a), the fixing portion 67, the lower piece 66, and the front piece 64 of the vertex cover 50 are cut in accordance with the roof slope at the parting line 68, and the center portion of the upper piece 65 is inverted V. By bending into a mold, as shown in FIG. 8 (b), it is possible to form the apex cover 50 bent so as to match the roof gradient. It is preferable to apply sealing material 69 to both ends of the vertex cover 50. Here, as shown in FIG. 8C, the ventilation parting material 1 is opposed to each other with a gap at the top part of the wife wall, and straddles between the opposing end parts of the ventilation parting material 1. The top cover 50 is disposed, and the front piece 64, the upper piece 65, and the lower piece 66 at both the left and right ends of the vertex cover 50 are overlapped on the outer surface of the end portion of the ventilation part 1 as shown in FIG. The opposite ends of the ventilation parting material 1 can be connected to each other. Then, the apex cover 50 can be fixed by hitting the overlapped portion of the fixing pieces 67 against the vertical body edge 46 with a fixing tool 71 such as a screw. At this time, the bulging portion 21 at the lower end portion of the front surface of the ventilation parting material 1 is adapted to be accommodated in the cutout portion 70 of the apex cover 50, and the apex cover does not interfere with the bulging portion 21. 50 can be attached. Further, as shown in FIG. 8C, a waterproof tape 62 is attached to the longitudinal trunk edge 46 at the opposite portion of the ventilation parting material 1 so that the waterproofness of the part where the ventilation parting material 1 is connected by the vertex cover 50 is ensured. It is.

  In the outer wall structure of the building formed with the ventilation parting material 1 as described above, the outer opening 6 of the ventilation parting material 1 is opened to the outdoors, and the inner opening 7 is the wall base 4 and the outer wall material 2. Therefore, the ventilation space 5 can be communicated with the outdoors through the outer opening 6, the ventilation path 8 and the inner opening 7. In this way, the ventilation between the ventilation space 5 and the outside air can be ensured by the ventilation parting material 1, so that the air in the communication space 5 flows into the inner opening 7 as shown by the arrow A in FIG. Then, the air flows into the ventilation parting material 1, passes through the ventilation path 8, and is exhausted from the outer opening 6. Therefore, it is possible to suppress an increase in humidity due to moisture being trapped in the ventilation space 5 between the wall base 4 and the outer wall material 2.

  Further, even if rainwater or the like blows into the air passage 8 from the outer opening 6 due to wind or the like, the water infiltrates into the air passage 8 as indicated by the arrow B in FIG. It is guided by the surface 9 and is blocked by the first water return 10a, falls from the first water return 10a to the outer inclined surface 9, is returned along the inclination of the outer inclined surface 9, and is opened from the outer opening 6 to the outside. Is discharged. Even if water intrudes further without being blocked by the first water return 10a, this water must first advance through the vertical air passage 8a, and the water enters the indoor side by climbing up the vertical air passage 8a. It is difficult. Furthermore, since the plurality of water return 10 including the first water return 10a are provided above the outer inclined surface 9 so as to protrude alternately from the indoor side and the outdoor side, 10 is obstructed. At this time, a path for water to enter while avoiding a plurality of water return 10 is a path that meanders upward, and the intrusion of water becomes extremely difficult due to the complexity of the path. Further, the water blocked by the water return 10 above the first water return 10 a falls downward from the water slice 25 at the tip of each water return 10, and the other water return immediately below this water return 10. 10 is received on the upper surface. The water on the upper surface of the water return 10 is guided to the tip side of the water return 10 by the inclination of the upper surface and falls downward from the water slice 25, finally reaches the outer inclined surface 9 and is discharged from the outer opening 6. . For this reason, the water blocked by the plurality of water returns 10 is efficiently sent to the outer opening 6 and discharged without remaining in the air passage 8.

  For example, even if water infiltrates up to the horizontal ventilation path 8b, it is difficult for water blown upward through the vertical ventilation path 8a to move horizontally in the horizontal ventilation path 8b to reach the inner opening 7. This water does not reach the inner opening 7 and adheres to the bottom of the lateral ventilation path 8b. The water adhering to the bottom of the horizontal air passage 8b moves along the inner inclined surface 11, falls from the tip of the third water return 10c to the vertical air passage 8a, and is blocked by the water return 10. Similarly, it is discharged from the outer opening 6. For this reason, the water that has entered the horizontal air passage 8b is also efficiently returned to the outer opening 6 and discharged without remaining in the air passage 8.

  Here, before the water that has entered the air passage 8 is discharged, the air current vigorously flows into the air passage 8 from the outer opening 6 during a strong wind, and the pressure in the air passage 8 is higher than the pressure in the air space 5. When it becomes higher, a strong air flow is generated from the air passage 8 toward the air space 5 due to the pressure difference, and there is a possibility that water in the air passage 8 is pushed out from the inner opening 7 to the air space 5 side by this air flow. However, since this air flow is efficiently shielded by the water return 10, an increase in pressure on the inner opening 7 side is suppressed. For this reason, the infiltration of water due to the pressure difference as described above is effectively prevented.

  In this way, it is possible to effectively prevent the water that has entered the air passage 8 from reaching the inner opening 7, and to suppress an increase in moisture between the wall base 4 and the outer wall material 2. It is something that can be done. Further, since the water in the air passage 8 is efficiently discharged from the outer opening 6, it is difficult for water to remain in the air passage 8, and the water evaporated in the air passage 8 passes through the inner opening 7. Inflow into the ventilation space 5 can be prevented, and an increase in moisture between the wall base 4 and the outer wall material 2 can be further effectively suppressed. The outer wall material 2 is connected to the upper and lower sides of the male and female seeds, and the rainwater that runs across the male and female seeds surface 72 is indicated by the arrow C in FIG. Thus, it is blocked by the sealing material 35 and discharged to the outdoor surface side, so that waterproofness is ensured.

  Here, when a horizontal wind blows on the outer wall material 2, the wind may rise along the surface of the outer wall material 2 as indicated by the arrow B in FIG. The wind that has risen along the air strikes the lower surface of the ventilation parting material 1, changes its direction to the outdoor side, and proceeds toward the outer opening 6 of the ventilation parting material 1. However, since the lower projecting piece 16 projecting downward is provided at the edge of the outer opening 6 on the outer wall material 2 side, the wind is blocked by the lower projecting piece 16 and moves downward as indicated by the arrow B in FIG. The direction is changed, and the wind can be prevented from flowing into the outer opening 6. Therefore, it is possible to prevent rainwater from entering from the outer opening 6 together with the wind, the waterproofness of the ventilation parting material 1 can be increased, and the infiltration of rainwater into the ventilation space 5 is made more effective. It can be prevented.

  In addition, when a side-by-side wind blows on the ventilation plate 1, the wind that blows on the front plate 20 of the ventilation plate 1 descends along the surface of the front plate 20 as indicated by the arrow C in FIG. 2. There is. Even when the wind descends along the front plate 20 in this way, the direction of the wind is converted to the outdoor side by the inclined portion 21a of the bulging portion 21 of the front plate 20 as indicated by the arrow D in FIG. For this reason, it is possible to prevent the wind from flowing around the lower surface of the ventilation parting material 1 by the bulging portion 21 and to prevent the wind from flowing into the outer opening 6 on the lower surface. Therefore, it is possible to prevent rainwater from entering from the outer opening 6 together with the wind, the waterproofness of the ventilation parting material 1 can be increased, and the infiltration of rainwater into the ventilation space 5 is made more effective. It can be prevented. Further, the wind blown against the front plate 20 is converted into a lateral direction somewhat by the unevenness 16 provided as described above over the entire length of the front plate 20, and the wind is changed to the outer opening 6 on the lower surface. It is possible to more effectively prevent inflow.

  As described above, water such as rainwater that has entered the air passage 8 of the ventilation parting material 1 from the outer opening 6 flows back toward the outer opening 6 without remaining in the air passage 8. The ventilation parting material 1 attached to the end wall as described above is inclined in the longitudinal direction along the gradient of the roof 3. For this reason, the water that has entered the ventilation path 8 flows in the ventilation path 8 along the longitudinal direction of the ventilation parting material 1 according to the inclination of the ventilation parting material 1 while flowing back to the outer opening 6. . Since the opening at the lower end of the slope of the ventilation part 1 is closed by the joint 37 and the end cap 52, the water that has flowed in the longitudinal direction in the ventilation part 1 is the joint 37 and the end cap 52. In a state where the weir is stopped and collected at the joint 37 and the end cap 52, it is discharged from the outer opening 6.

  Here, as described above, the joint 37 and the end cap 52 are provided with the water stopper piece 30 extending to the end plate 29 on the outdoor side, and the water guide piece 31 is provided over the water stopper piece 30. The water guide piece 31 is positioned directly below the outer opening 6 of the ventilation parting member 1. Therefore, when the water collected after being blocked by the joint 37 and the end cap 52 is discharged from the outer opening 6, this water is received by the water stopper piece 30 and the water guide piece 31 located immediately below, The surface of the outer wall material 2 after flowing over the water guide piece 31 in the outdoor direction from which the water stopper piece 30 protrudes as shown by the arrow B in FIG. 1B or the arrow B in FIG. It flows down from the tip of water guide piece 31 in a position away from. For this reason, it is possible to drain water while effectively suppressing the water discharged from the outer opening 6 of the ventilation parting material 1 from flowing along the surface of the outer wall material 2. It is possible to effectively suppress the adhesion of scales or the like due to the flow of water on the surface.
