The present invention relates to a building outer wall corner component material that can be constructed.

(Prior art and its problems) In buildings constructed using the conventional dry construction method, in order to fix the outer wall corner materials when constructing the outer wall corners of the building, for example, as shown in Figure 7, long and narrow pieces joined at right angles are used. L-shaped fasteners b are fixed at intervals to the inner surfaces of the rectangular corner plates a, a by screws, etc., and both ends c, c of the fasteners b are attached to the outer wall adjacent to the plate a. This was done by nailing to the bottom part f of the joint part e formed between the board d. In addition, in order to seal the joints e, e and the triangular joint g formed at the joint between the plates a, a, the joints e, e and the triangular joint g should be filled with caulking agent h. I was going there. However, in the case of such a conventional exterior wall corner configuration, in addition to requiring a great deal of effort to attach the plates a, a forming the exterior wall corner, sealing of the joints e, e and the triangular joint g is difficult. In some cases, the filled joint material may loosen or come off due to variations in the caulking filling process, changes in temperature, vibrations of the building structure, etc., and rainwater may enter through it and corrode pillars, etc. It was hot. Also, the joints and triangular joints finished by filling with caulking agent were not pleasing in appearance. Furthermore, since caulking agents are expensive and require a lot of effort to fill, there were also demands to refrain from using them as much as possible.

In FIGS. 1 and 2, the structural material 1 of the present invention includes an external wall corner material 3 forming an external wall corner part 2 of a building;
It consists of a mounting member 4 that holds the outer wall corner material 3 and a joint member 5 that is integrally combined with the mounting member 4.

The outer wall corner material 3 is made of, for example, an inorganic material, has an angular shape, and has, for example, T-shaped grooves 6, 6 on both end portions 3a, 3a of the inner surface thereof. .

In this embodiment, the mounting member 4 is an integrally molded product made of hard synthetic resin, and is attached to the bottom part (for example, a wooden fixing part) of the joint part 9 formed between the outer wall corner material 3 and the adjacent outer wall board 7. The groove 6 of the outer wall corner material 3 is attached to one end of the fixed piece 11 fixed to the outer wall corner material 3.
An engagement piece 16 having a T-shaped piece 13 that engages with the tip of the L-shaped piece 15 that contacts the inner corner part of the outer wall corner material 3 is connected, and the longitudinal center of the outer surface 17 of the fixed piece 11 The part has a saw-blade-like uneven part 19.
A first locking portion 20 consisting of a locking groove 20a having a locking groove 20a on the inside is formed by opposing locking protrusions 21, 21.

On the other hand, the joint member 5 includes an inner surface of a base portion 22 made of hard synthetic resin and a rectangular plate shape (a bottom surface 1 of the joint portion).
The above-mentioned locking groove 2 is provided on the surface (face portion) 23 facing 0.
A locking protrusion that can be fitted and engaged with the first locking portion 20 as 0a (the uneven portion 25 that engages with the uneven portion 19
A second locking part 26 as (26a) is formed integrally with the base part 22, and an elastic part made of, for example, soft foamed synthetic resin is formed so as to cover both side parts 27, 27 and outer surface part 29 of the base part 22. A seal portion 30 is provided. In addition, the elastic seal parts 3 on both sides
The outer surfaces 31, 31 of the elastic seal portions 0a, 30a are approximately parallel to the side surfaces 27, 27 of the base portion 22, respectively, and the distance between the outer surfaces 31, 31 of the elastic seal portions 30a, 30a on both sides is 30a, 3
It is made slightly larger than the width of the joint portion 9 in consideration of the necessary compression amount of 0a.

However, after the mounting member 4 is attached to the outer wall corner material 3 by fitting the T-shaped pieces 13 into the grooves 6 provided on both sides of the outer wall corner material 3, the inner surface of the fixing piece 11 is connected as a joint. When the fixing piece part 11 is brought into contact with the bottom part 10 of the part 9 and is nailed to the bottom part 10 on both sides of the first locking part 20, the outer wall corner material 3 will be attached to the mounting members 4 on both sides thereof. ，

In addition, in order to further enhance the sealing effect, as shown in FIG.
An appropriate amount of caulking agent 33 may be applied to the bottom surface portion 10 of.

FIG. 3 shows another example of the joint member 5, in which the cross-sectional shape of the base portion 22 is similar to that of the inner surface 3.
It differs from the previous embodiment in that it has a trapezoidal shape in which the width of the outer surface portion 36 is slightly smaller than the width of the outer surface portion 36. When the joint member 5 is configured in this way, the joint member 5 is constructed as shown in FIG.
When the first and second locking portions 20 and 26 are fitted into the joint portion 9 and press-fitted into the joint portion 9,
Elastic seal parts 30a, 30a on both sides of the base part 22
Since the repulsive force becomes weaker from the outer part 37 toward the inner part 39, the joint member 5 can be easily press-fitted into the joint part 9. In each of the cases described above, the base portion 22 may be formed hollow, for example as shown in FIG. 5 is made lightweight to improve its handling.

Further, FIG. 6 shows another modification of the joint member 5 that can achieve the same effects as the joint member 5 shown in FIG.
0 is formed in a step-like shape with a narrow width.

In addition, the attachment member 4 does not necessarily have the same length as the joint member 5, and may be formed as a piece. Further, the mounting member 4 may be made of metal. Further, in the joint member 5, the side surfaces of the elastic seal portions 30a, 30a provided on both sides of the base portion 22 may be formed into fin shapes. The elastic seal portion 30 may be made of synthetic rubber or soft synthetic material as long as it allows the joint member 5 to be easily fitted into the joint portion 9 and exhibits an effective sealing effect in the fitted state. Although it can be formed using a resin or the like, the soft foamed synthetic resin shown in the above embodiment is particularly preferable.

(Effects of the invention) The components of the invention include an outer wall corner material having grooves on the end portion of the inner surface, and a mounting member that holds the outer wall corner material on the inner surface and includes a first locking part. and a joint member having a second locking portion that can be elastically fitted and engaged with the first locking portion.As a result, the outer wall corner material can be reliably fixed without impairing its appearance. In addition to being able to be installed efficiently, the joint formed between the exterior wall corner material and the exterior wall board can be finished simply and quickly, and with a good appearance. In addition, since the joint member is provided with elastic seal parts on at least both sides that are pressed against the side surfaces of the joint part and compressed elastically, even if there is some variation in the width of the joint part, the same joint member can be used. The joints can be treated using Furthermore, since the joint material is press-fitted into the joint with the elastic seal part compressed, unlike the conventional joint treatment by filling with caulking agent, The joint member will not loosen or come off even due to vibrations, and a reliable sealing effect will be maintained.

Note that the elastic seal portions in the joint member need only be provided on both side surfaces of the base portion, but as shown in the embodiment, it is possible to provide the elastic seal portions so as to cover both side surface portions and the outer surface portion of the base portion. In addition, it is possible to perform joint treatment with even better appearance.
