  Hereinafter, the outer wall joint gasket 1a and the outer wall joint seal structure 2 according to the present invention will be described with reference to the drawings. The outer wall joint gasket 1a constituting the outer wall joint seal structure 2 is pressed into a gap between the outer wall panels 3 of a building such as a house to prevent wind and rain from entering the indoor side of the outer wall panel 3 from the outside, and It is a joint material that improves the design of the exterior of the building.

  As shown in FIGS. 1 and 2, the outer wall joint gasket 1a is a joint material made of, for example, rubber or resin that can be press-fitted into either a vertical joint or a horizontal joint of the outer wall. A long gasket body 5 having a rectangular cross section formed narrower than the joint width so that it can be inserted into the joint body, and is formed so as to spread on both sides of the gasket body 5, and is formed in a bowl shape on both sides of the gasket body 5. And a support portion 7 formed on both side edges of the front end of the gasket body 5 and a fixing portion 8 having a substantially V-shaped cross section whose bent position is fixed to the support portion 7.

  For example, two seal portions 6 are formed on each side surface of the gasket body 5, and the length from the tip of the seal portion 6 formed on one side surface to the tip of the seal portion 6 formed on the other side surface is long. The seal portion 6 is longer than the joint width, and is formed so that the seal portion 6 is elastically deformed when being press-fitted into the joint 4 so that the tip thereof is in watertight contact with the respective side surfaces of the outer walls. Note that the number of the seal portions 6 is not limited to this, and it is sufficient that at least one seal portion 6 is formed on each side surface of the gasket body 5. Further, the shape of the seal portion 6 is not limited to the bowl shape as described above, and various other shapes can be applied as long as the shape can be brought into watertight contact with the side surface of the outer wall panel 3. it can.

  The support part 7 supports the fixed part 8 in a swingable manner by its elastic deformation. The fixed portion 8 includes an extending portion 9 extending in the direction of the outer wall panel 3 and a depth end portion 10 extending in the depth direction of the joint 4, and is supported at a bent position between the extending portion 9 and the depth end portion 10. Supported by the department. In addition, each part which comprises the outer wall joint gasket 1a may be what was integrally molded by the same material, and when comprised in this way, a manufacturing process can be simplified and the procurement cost of material can be reduced. For example, by forming the support portion 7 with a softer elastic body than the other, the fixing portion 8 can be formed more easily to swing, and the depth end portion 10 is harder than the others. You may comprise so that it may fix to the joint 4 reliably in an appropriate depth position, when it press-fits into the joint 4 by forming with an elastic body. Moreover, you may make it the structure which prevents that the outer wall joint gasket 1a is distorted unnecessarily by fixing a hard core material inside the gasket main body 5.

  For example, a protrusion 11 is formed on the side surface of the outer wall panel 3 constituting the seal structure 2 of the outer wall joint. The protrusions 11 are provided in advance when the outer wall panel 3 is manufactured by extrusion molding or the like, and are formed over the entire side surface of the outer wall panel 3 constituting the vertical joint or the horizontal joint. Such ridges 11 may be formed on the side surface of the outer wall panel 3 at predetermined intervals. That is, the object of the present invention can be achieved as long as the depth end portions of the outer wall joint gasket 1a can be fixed.

At this time, first, when the extension portion 9 comes into contact with the outdoor surface of the outer wall panel 3 near the joint 4 and the outer wall joint gasket 1a is pushed in as it is, the support portion 7 is elastically deformed, and the extension portion 9 becomes the gasket body 5. The depth end portion 10 rotates in the side surface direction of the outer wall panel 3. Then, when the outer wall joint gasket 1a is further press-fitted, as shown in FIG. 4, the seal portion 6 is also press-fitted into the joint 4 and abuts the side surface of the outer wall panel 3 in a watertight manner, and the distal end of the depth end portion 10 is at the outer wall panel 3. It abuts on the ridge 11 formed on the side surface of the.

  In this way, the outer wall joint gasket 1a is restricted by the ridges 11 and cannot be press-fitted in the indoor direction any more, so that the outer wall joint gasket 1a can be prevented from falling off to the indoor side. Then, by appropriately designing the depth position of the joint 4 of the ridge 11, the outer wall joint gasket 1a can be fixed at the most appropriate position from the viewpoint of watertightness and design as the sealing material of the joint 4.

  As shown in FIG. 5, the side surface of the outer wall panel 3 constituting the outer wall joint sealing structure 2 may be formed with grooves 12 instead of the ridges 11. The groove portion 12 may be formed over the entire side surface of the outer wall panel 3 constituting the vertical joint or the horizontal joint when manufactured by extrusion molding or the like, similarly to the protrusion 11, or a hole shape formed at a predetermined interval. It may be. Moreover, when formed in the predetermined space | interval, the groove part 12 may be the through-hole formed by penetrating from one side surface of the outer wall panel 3 to the other side surface, for example.

  When the groove 12 is formed on the side surface of the outer wall panel 3 as described above, the outer wall joint gasket 1a is press-fitted into the joint 4 from the outdoor side as in the case where the ridge 11 is formed, and the seal portion 6 is formed on the outer wall panel. 3, and the front end of the depth end portion 10 is hooked on the step on the indoor side of the groove portion 12 formed on the side surface of the outer wall panel 3. It is possible to prevent the outer wall joint gasket 1a from falling out indoors. The side wall of the outer wall panel 3 is often formed with a groove or a hole, and the outer wall joint gasket 1a can be used for the outer wall panel 3 as well.

  Further, the side surface of the outer wall panel 3 constituting the seal structure 2 of the outer wall joint is not limited to the one in which the protrusion 11 or the groove 12 is formed in the manufacturing process such as extrusion molding, for example, FIG. As shown, the plate member 13 formed in a thin long cube may be fixed to the side surface of the outer wall panel 3. For example, the plate member 13 is fixed over the entire side surface of the outer wall panel 3 using fixing means such as screws, nails, or adhesives, or at predetermined intervals. When the gasket 1a is press-fitted, the tip of the depth end portion 10 abuts on the plate member 13, so that it is no longer possible to press-fit in the indoor direction, and the outer wall joint gasket 1a is prevented from falling off to the indoor side. Can do. The outer wall joint gasket 1a can be used by fixing the plate member 13 also in the outer wall panel 3 in which the protrusions 11 and the groove portions 12 are not formed on the side surfaces. Then, by fixing the plate member 13 at an appropriate depth position of the joint 4, the outer wall joint gasket 1 a can be fixed at the most appropriate position from the viewpoint of watertightness and design as a sealing material of the joint 4.

  The protrusions 11, the grooves 12, and the plate member 13 described above are not limited to those formed as a pair on both sides of the side surface of the outer wall panel 3 that constitutes the joint 4, and for example, one of them facing each other. The protrusion 11 may be formed on the side surface of the outer wall panel 3, and the groove portion 12 may be formed on the side surface of the other outer wall panel 3. In addition, any combination of the ridge 11, the groove 12, and the plate member 13 may be formed on the side surface of the opposing outer wall panel 3.

  In addition, as shown in FIG. 7, the protrusion 11 is provided closer to the indoor side of the outer wall panel 3, and the outer wall joint gasket 1 a is deeply pressed into the joint 4 to provide a space on the outdoor side of the joint 4. A wet caulking agent 14 may be injected into this space. That is, the outer wall joint gasket 1a can be used not only as a sealing material for the joint 4, but also as a base material for the caulking agent 14. By comprising in this way, the caulking agent 14 can be inject | poured by appropriate thickness, the caulking agent 14 is too thin, and the caulking agent 14 is too thick as necessary, and the caulking agent 14 is too thick. It is possible to prevent problems such as poor curing and increased material costs.

  Next, as another embodiment of the outer wall joint gasket 1, an outer wall joint gasket 1b will be described with reference to FIGS. In addition, about the structure similar to the outer wall joint gasket 1a, the same code | symbol is attached | subjected and description is abbreviate | omitted. The outer wall joint gasket 1 b has a support portion 7 formed on one side edge at the tip of the gasket body 5, and a fixing portion 8 having a substantially V-shaped cross section is fixed to the support portion 7. A seal portion 6b is formed on the other side edge of the front end of the gasket body 5 so as to be elastically deformed when pressed into a joint and to be in close contact with the side surface of the outer wall panel. And the groove part 12 is formed in the side surface of the one side of the outer wall panel 3 which comprises the seal structure 2 of an outer wall joint, for example.

  When the outer wall joint gasket 1b is press-fitted into the joint 4, as shown in FIG. 9, the outer wall joint gasket 1b is pushed in from the outdoor side, and the extension 9 is brought into contact with the outdoor surface of one outer wall panel 3 in the vicinity of the joint 4. Let Then, the outer wall joint gasket 1b is pushed into the joint 4 as it is, the support portion 7 is elastically deformed, the extension portion 9 is tilted in the side surface direction of the gasket body 5, and the depth end portion 10 is moved in the side surface direction of the outer wall panel 3.
