Description

[Detailed Description of the Invention] The present invention relates to a gasket jointer for exterior walls used for joint construction of building material boards for exterior walls.

Conventionally, when jointers with a simple E-shaped cross-sectional shape were used for exterior walls, rainwater easily entered through the gap between the jointer and the building material board.In addition, jointers with elastic foam attached to the contact surface with the construction material board, which mainly consists of joiners, were used for external walls. However, if the contact pressure with the building material board is not sufficient, rainwater tends to enter through the gap between the elastic foam material and the building material board due to capillary action, and the contact surface of the building material board usually becomes uneven in the longitudinal direction. If the butt end surface is likely to cause cracking, a gap is likely to be formed between the concave portion and the joiner, making it difficult to prevent rainwater from seeping through the concave portion of the butt end surface.

Therefore, the present invention has been developed to provide a gasket for exterior walls that has excellent adhesion to the contact end surface of the building material board, good ability to follow the expansion, contraction, and bending of the building material board, and has excellent waterproof properties at the contact area with the building material board. The purpose is to provide a joyner.

Next, an embodiment of the present invention shown in FIGS. 1 and 2 will be described. The joiner main body 1 of this embodiment is a metal plate bending member 2 whose required portions are covered with a soft synthetic resin member 3. The folding member 2 has a vertical piece 4 that has been folded back in half, and the upper end of the vertical piece 4 is formed into an upper piece 5 that bulges out in a long oval shape from side to side, and the lower end of the vertical piece 4 is bent outward from the left and right. The overall cross-sectional shape of the horizontal piece 6 is E-shaped, and the soft synthetic resin member 3 is attached to the outer surface of the upper piece 5 and the vertical piece 4 of the bending member, and to the upper surface of the base of the left and right horizontal pieces 6. The layers are laminated to an appropriate thickness. At the upper portions of the left and right edges of the soft synthetic resin member 3 in the upper piece 5 of the joiner main body 1, elastic tongue pieces 7 made of soft synthetic resin whose tips are inclined outwardly and downwardly are connected. On both sides of the lower part of the soft synthetic resin member 3 in the vertical piece 4 of the body, elastic water return pieces 8 made of soft synthetic resin with their tips slanted outward and upward are connected to the horizontal piece 6 of the main body of the Joyner. On the upper surface of the soft synthetic resin member 3, soft synthetic resin protrusions 9 are arranged in a row at appropriate intervals in the width direction, and at the outer end of the horizontal piece 6 of the joiner main body, the tip side is directed inward and upward. A folded portion 10 is formed, and the tip of the folded portion 10 and the tip of the projection 9 are aligned in substantially the same horizontal plane.

When installing the jointer of this example at the joint, as shown in FIG. Insert the horizontal piece 6 and press the tongue piece 7 of the end surface 14 of the side surface of the building board 13 and the horizontal piece 6, and in a bent state, permanently fasten the building board 13 to the base material 11 with nails 15, The back surface of the building material board 13 is pressed against the protrusion 9 and the folded part 10, and the end surface 14 of the adjacent building material board 13 is pressed against the other tongue piece 7 and water return piece 8.
The building material board 13 is permanently fastened to the base material 11 with nails 15 in a bent state. Note that the temporary nails 12 are unnecessary except for use in constructing the first building material board 13.
Further, if necessary, a caulking material 17 is applied to the joint 16 on the upper surface of the joiner between the building material plates 13, 13.

In this construction state, the end surface 14 of the building material board is
Since the tongue pieces 7 are in close contact with each other due to the bending reaction force,
Infiltration of rainwater from the joint 16 is prevented by the close contact between the tongue piece 7 and the end surface 14, and when the building material board 13 expands, contracts or bends, or when the end surface 14 becomes slightly meandering in the longitudinal direction. Even in the case where the tongue piece 7 has elasticity, the tongue piece 7 follows the end face 14 closely and achieves the above-mentioned waterproofing effect, and in this example, in the unlikely event that rainwater passes between the end face 14 and the tongue piece 7, Wood end surface 14
The water return piece 8 is prevented from entering downward by the water return piece 8 which is elastically in close contact with the building material board 13.
It is blocked by a plurality of protrusions 9 that are close to the back surface, and in the unlikely event that rainwater passes through these protrusions 9, it is further absorbed by the building material board 1.
3 is blocked by the folded portion 10 that is in close contact with the back surface.
The folded portion 10 also increases the bending strength of the joiner in the longitudinal direction.

FIG. 3 illustrates the case where the upper piece part 5 of the above example is not provided, and in this case, the joiner main body 1'
Elastic tongue pieces 7' similar to the previous example are directly connected to both sides of the upper end of the vertical piece 4'.

As described above, in the present invention, the jointer main body is constructed by covering the upper end of the vertical piece of a metal bending member with horizontal pieces on both sides of the lower end of the vertical piece with a soft synthetic resin member. This means that flexible tongue pieces made of soft synthetic resin are provided on both sides of the upper end of the vertical piece of the joiner main body for contacting the end surface of the building material board, and a soft synthetic resin member is laminated on the upper surface of the horizontal piece. During construction, the elastic tongue can be pressed tightly against the end surface of the building board in a bent state, and the tongue can easily follow the expansion and contraction of the building board and the bending of the end surface. This improves the waterproofness of the end surface, and the jointer does not protrude from the outside surface of the building board, giving it an excellent appearance. It can also be applied to the joints of building boards of various thicknesses. It is possible to perform double waterproofing with synthetic resin members, and since the bending member of the joiner is made of metal, it has fire retardant properties, and in combination with the waterproofness of the end surface due to the conformability mentioned above, it is possible to perform double waterproofing. Excellent as a butt-jyoner.
