Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint joiner and an exterior corner accessory.

[0002]

2. Description of the Related Art In general, a fiber reinforced cement wallboard has a gouged shape at the widthwise end of the wallboard A as shown in FIG. 12 in order to increase the joint strength of the joint and prevent rainwater from penetrating from the joint. Alternatively, the joining steps B and B (the illustrated example shows a gouged joining step) having the actual shape are provided. Therefore, there is almost no problem in rainwater infiltration at the joints of the wall plates A that are joined at the joining steps B and B, but the cut end faces of the wall plates A in the length direction (arrow X direction) are flat cuts. Since the surfaces are made to be surfaces, waterproof treatment is required for these joints.

As a conventional waterproofing treatment, as shown in FIG. 13, both wall plates are formed on the surface of a band-shaped substrate C having a width extending between the wall plates A and A in a joint gap between the wall plates A and A end faces abutting each other. It has been performed that stoppers D, which regulate the joint gap between them, and joiner materials E with standing D are arranged, wall boards A, A are attached, backup materials F are arranged, and joint filler G is filled. . Further, as shown in FIG. 14, in the projecting corner portion of the outer wall, the wall boards A and A end surfaces aligned at the projecting corner P are treated with the projecting corner accessory H having the receiving portion H1.

[0004]

However, since the joint joiner E and the projected corner accessory H have different shapes, it is necessary to prepare each joint joiner according to the state of the wall surface, and such two kinds of members are required. Depending on the situation, there is a drawback that it is troublesome to install, install or manage and store.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention facilitates construction and the like by allowing a joint joiner used for a flat portion to also serve as a projected corner portion. It was made for the purpose.

[0006]

[Means for Solving the Problems] That is, the joint joiner according to claim 1 is a vertical joint between wall plates A, A connected to a central surface zone of a strip-shaped substrate 1 arranged on a wall base surface. A pair of wall plate stoppers 2, 2 are installed upright with a space provided therebetween.
It is characterized in that a notch groove 3 which allows the band-shaped substrate 1 to be bent is continuously provided in the longitudinal direction in the central portion of the surface between the wall plate stoppers 2 and 2.

The joint joiner according to a second aspect is the joint joiner according to the first or second aspect, wherein the inner surface of any one of the wall plate stoppers 2 and 2 is filled with a gap between the wall plate stoppers 2 and 2. It is characterized in that the backup material 5 for the sealing material is attached.

A joint joiner according to a third aspect of the present invention is the joint joiner according to the first aspect of the present invention, in which the opposing edges 6 and 6 extending equidistantly in opposite directions are provided at the top edges of the wall plate stoppers 2 and 2. It is characterized by being integrally formed.

A joint joiner according to a fourth aspect relates to the joint joiner at the projected corner portion, and has a cross section L covering the projected corner portion of the outer wall.
A cover body 7 in the shape of a letter, and legs 8 and 8 which engage with the wall plate stoppers 2 and 2 which stand up when the joint joiner according to claim 1 or 2 is bent in the notch groove 3 on its inner surface. Is provided.

[0010]

The band-shaped substrate 1 of the joint joiner according to claim 1.
Is inserted along the joints of the wall boards A and A, mainly along the vertical joints, to waterproof the vertical joint portions. Further, the wall plate stoppers 2, 2 provided upright on the surface regulate the joint space between the end faces of the wall plate A. The notch groove 3 provided in the center between the wall plate stoppers 2 and 2 is used when the strip-shaped substrate 1 is bent along the projected corner portion, and the lower ground surface and the end surface of the wall board A in the projected corner portion are aligned. . The space between the stoppers 2 and 2 is used as a space for mounting the sealing material 10, and
It itself is used to fix the projectile.

It should be noted that in the above-mentioned joint joiner, it is also possible to provide concavo-convex stripes 4 ... 4 which are continuous in the longitudinal direction of the wall plate stoppers 2 and 2 on the outer surfaces of the wall plate stoppers 2 and 2, respectively. Article 4 ... 4, the leg part 8 of the Dekaku character,
It may also be used as an engaging ridge with 8.

The backup material 5 for the sealing material in the joint joiner according to the second aspect serves as a base material when the sealing material 6 is put on, and effectively prevents the joint from being broken by so-called three-sided adhesion.

Further, since the backup material 5 is adhered to the inner surface of either one of the wall plate stoppers 2 and 2, it does not fall off during construction, and the joint joiner is provided on the projecting corner portion. Even when it is bent along, it will not stick to the inner surface of one stopper 2 and fall off.

In the joint joiner according to the third aspect of the present invention, the opposing edges 6 and 6 extending equidistantly in opposite directions to the top edges of the wall plate stoppers 2 and 2 serve as backup materials.
There is no need to attach a backup material separately. Moreover, since the facing edges 6 and 6 are not continuous with each other, the bending of the strip substrate 1 at the notch groove 3 is not hindered.

A joint joiner according to a fourth aspect is the joint joiner according to the first, second, third, or fourth notch groove 3.
When it is bent and attached to the projecting corner, the legs engage with the upright wall plate stoppers 2 and 2 to cover the projecting corner.
