Thus, each plate member is locked to the joining member by at least one of the protrusions, with the mounting base end portion being sandwiched between the outer side and the inner side of the joining member. Then, the pair of plate members are attached to the joining member in a state in which the tips of the plate members are directed in different directions, for example, at right angles, and the projected corner material is completed.

As described above, according to the present invention, by assembling the above-mentioned plate member and the above-mentioned joining member and integrating them, the projected corner member can be formed as required. Therefore, the plate member and the joining member can be separately packaged and transported, for example, from a factory to a construction site. Therefore, the plate members can be stacked with a narrower width than the conventional one. Also, the above-mentioned joining members can be compactly bundled.
Therefore, these can be packed and transported in a compact state. Further, since the plate member and the joining member can be transported separately, handling during transportation is easy.

Further, by cutting the plate member at the construction site and adjusting the width dimension of the plate member to a desired size according to the size of the projecting corner portion, the size of the projecting corner material can be adjusted. You can change it freely. As a result, it is possible to easily form the projected corner material of a size suitable for each construction site, which facilitates site correspondence.

When the plate member is cut, the mounting base end side of the plate member is cut off, so that the width dimension of the plate member can be adjusted without cutting off the tip end side of the plate member. Therefore, when the shape of the tip of the plate member is difficult to form at the construction site, for example, when a real part is provided at the tip of the plate member, on-site response becomes particularly advantageous. The insertion groove can be easily formed at the construction site by using, for example, an electric saw or a cutter.

Further, since the insertion groove is provided on the back side surface of the plate member, even if rain water or the like goes around the back side surface of the mounting base end portion, the rain water or the like is inserted into the insertion groove. Since it is possible to divide and block water, the water-stopping effect can be enhanced.

Next, as in the invention of claim 2, it is preferable that the joint member is formed by integral molding. Examples of the material of the joining member include aluminum material, stainless material, and synthetic resin.

It is preferable that the provided insertion groove is located closer to the mounting base end side of the plate member than the insertion groove provided on the back side surface of the plate member.

In this case, when the mounting base end portion of the plate member is fitted into the mounting recess of the joining member, the protrusion provided on the inner side of the joining member is attached to the back side surface of the mounting base end portion. Not only can it be fitted into the insertion groove provided in the above, but both end portions of the outer side of the joining member can be fitted into the insertion groove provided on the front side surface of the attachment base end portion. Therefore, the plate member can be firmly attached to the joining member. Further, the outer side of the joining member is not covered with the projection provided on the inner side of the joining member, and the plate member is easily attached to the joining member.

Next, the invention of claim 4 comprises assembling the pair of plate members and the joining member, wherein the mounting base of the plate member is provided between the outer side and the inner side of the joining member. According to another aspect of the present invention, there is provided an assembly type corner material, characterized in that an end portion is sandwiched and the projection portion of the joining member is fitted in the insertion groove of the plate member. Examples of the wall base material include wooden furring strips and C-shaped channel materials.

The mounting base end portion 21 of the plate member 2 is provided with insertion grooves on its front side surface 22 and back side surface 23, respectively. The insertion groove provided on the front side surface 22 of the plate member 2 (hereinafter, front side insertion groove 212) is attached to the plate member 2 more than the insertion groove provided on the back side surface 23 of the plate member 2 (hereinafter, back side insertion groove 213). It is located on the base end 21 side. Although not shown,
A pattern is formed on the front side surface 22 of the plate member 2. Further, the plate member 2 has a stepped real portion (hereinafter, lower real portion 25) at the tip end portion 24 opposite to the mounting base end portion 21.

The joining member 3 has outer and inner sides 31 and 3 which are bent and formed so that both ends thereof are different from each other by about 90 degrees.

Further, the joining member 3 has a pair of mounting recesses 34, 34 between the outer side 31 and the inner side 32 into which the respective mounting base end portions 21 of the pair of plate members 2, 2 are fitted. . The mounting recess 34 has a parallelogram in cross section (FIGS. 1 to 3).

Further, at both ends of the outer side 31 of the joining member 3, there are provided protrusions (hereinafter referred to as outer protrusions 312) to be fitted into the front insertion grooves 212.
At both ends of the inner side 32, a protrusion (hereinafter referred to as an inner protrusion 323) fitted in the back side insertion groove 213 is provided.

The joint member 3 is formed by integral molding. That is, the outer side 31, the inner side 32, and the connecting side 33 are integrally provided by extruding an aluminum material. In addition, in the inner protruding portion 323, the tip portion of the inner side 32 is provided with a mounting recess 34

Next, the function and effect of this example will be described. In this example, by mounting the pair of plate members 2 and 2 on the joining member 3, it is possible to assemble the assembled corner projection member 10 (FIG. 2). That is, when assembling the assembly type corner material 10, each mounting base end portion 2 of one plate member 2 is used.
1 is fitted into one of the mounting recesses 34 of the joining member 3, and the mounting base end portion 21 of the other plate member 2 is fitted into the other mounting recess 34 of the joining member 3. At this time, the inner protrusion 323 of the joining member 3 is fitted into the back side insertion groove 213 of the plate member 2, and the outer protrusion 312 of the joining member 3 is fitted into the front side insertion groove 212 of the plate member 2.

As a result, the pair of plate members 2 and 2 are
The front end portions 24 are attached to the joining member 3 in a state in which they are oriented in directions different from each other by about 90 degrees, and the assembly-type projected corner material 10 as shown in FIG.

The assembly type corner material 10 is constructed by assembling and integrating the pair of plate members 2 and 2 and the joining member 3. Each of the plate members 2 has the mounting base end portion 21 sandwiched by the outer side 31 and the inner side 32 of the joining member 3 from both the front and back surfaces, and the two protruding portions (the outer protruding portion 31).
2, the inner protruding portion 323) is fitted and locked to the joining member 3. Since each plate member 2 can be removably attached to the joining member 3, the assembly type corner member 10 can be separated into a pair of plate members 2 and the joining member 3 as needed.

The construction structure of the above-mentioned prefabricated corner material 10 is shown in FIG.
Shown in. The prefabricated corner material 10 is driven by nails 8 at the plate member 2, and the vertical furring strip 4 as a wall base material is used.
It is fixed to. The outer wall plate 5 disposed adjacent to the plate member 2 is fixed to the vertical furring strip 4 by a nail 8 with its side end portion 54 abutting the lower solid portion 25 of the plate member 2. In the figure, reference numeral 61 is waterproof paper, reference numeral 62 is a pillar, and reference numeral 63 is a caulking material.

In this embodiment, the plate type member 2 and the joining member 3 are assembled and integrated with each other, so that the assembly type projected corner member 10 can be formed as required. Therefore, the plate member 2 and the joining member 3 can be separately packaged and transported from the factory to the construction site. Therefore, the plate member 2 can be stacked in a flat plate shape with a narrower width than the conventional one. Also, the joining member 3
Can be compactly bundled. Therefore, these can be packed and transported in a compact state. Further, since the plate member 2 and the joining member 3 can be separately transported in a compact state, handling during transportation is easy.

Further, by cutting the plate member 2 at the construction site and adjusting the width dimension of the plate member 2 to a desired size according to the dimension of the projecting corner portion, the size of the assembly type projecting corner member 10 is adjusted. Can be freely changed at the construction site. Therefore, the assembly-type projected corner material 10 having a size suitable for each construction site can be easily formed, which facilitates site correspondence.

When the plate member 2 is cut, the mounting base end 21 side of the plate member 2 is cut off so that the lower solid portion 25, which is difficult to form at the construction site, is not cut off.
Since the width dimension of can be adjusted, on-site response is particularly advantageous. Further, the back side insertion groove 213 can be easily formed at the construction site by cutting using an electric saw.

As in Japanese Utility Model Publication No. 4-92936,
In the case where the plate member 2 and the joining member 3 are previously integrated, the side of the mounting base end 21 of the plate member 2 cannot be cut, so that the end 24 side of the plate member 2 must be cut off. I won't. However, the lower solid portion 25 has a lower insertion groove 213.
It cannot be easily formed on-site like. Therefore, in this case, it is very difficult to adapt the dimension of the corner material to each construction site.

The joining member 3 is formed by integral molding. Therefore, the joining member 3 can be easily manufactured by extruding the aluminum material. Moreover, the durability of the joining member 3 at the time of packing, transportation, etc. can be improved. Further, since the aluminum material is used as the material of the joining member 3, the plate member 2
Since the joining member 3 can be slightly deformed at the time of fitting, the fitting base end portion 21 of the plate member 2 can be easily fitted into the fitting recess 34 of the joining member 3. Further, even after the construction, even if the dimensions of the plate member 2 change due to thermal expansion or the like, the extension can be absorbed by the mounting recess 34 of the joining member 3.

The mounting base end 21 of the plate member 2 is provided with the front insertion groove 212 and the back insertion groove 213, and the joining member 3 is provided with the outer protrusion 312 and the inner protrusion 323. There is. Therefore, when the mounting base end portion 21 of the plate member 2 is fitted into the mounting recess 34 of the joining member 3,
Not only can the inner protrusion 323 be fitted in the back insertion groove 213, but the outer protrusion 312 can be fitted in the front insertion groove 212. Therefore, the plate member 2 can be firmly attached to the joining member 3. This method works particularly effectively when the front surface 22 of the plate member 2 has irregularities (see Embodiment 4).

In addition, the inner protrusion 323 is formed on the back side insertion groove 21.
Since the plate member 2 can be locked to the joint member 3 by fitting the outer protrusion portion 312 to the joint member 3, the outer protruding portion 312 is loosely fitted in the front insertion groove 212 with some play.

The front insertion groove 212 of the plate member 2 is located closer to the mounting base end 21 side than the back insertion groove 213. Therefore, the outer side 31 of the joining member 3 does not cover the inner protruding portion 323 of the joining member 3, and the plate member 2 is easily attached to the joining member 3.

Further, as shown in FIG. 2, in the assembly type corner material 10 of this example, the plate member 2 is mounted between the outer side 31 and the inner side 32 of the joining member 3 (the mounting recess 34). By sandwiching the base end portion 21, the pair of plate members 2 can be mounted on the joining member 3. Therefore, it is not necessary to provide a wavy bent portion in the joining member 3 for mounting the plate member 2, and the wavy bent portion is not visible from the outside when the wavy bent portion is applied. Therefore, it is possible to improve the appearance of the assembled corner projection member 10.

Further, as shown in FIG. 3, in the construction structure of this embodiment, the assembly-type projected corner material 10 is fixed to the vertical furring strip 4 at the plate member 2. Therefore, both end portions (near the tip end portion 24 of the plate member 2) of the assembly-type corner projection member 10 can be fixed to the vertical furring strip 4, so that the assembly-type projection corner material 10 can be firmly attached without rattling.

Further, the mounting recess 34 of the joining member 3 can function as a gutter, and rainwater or the like can be promptly discharged. Further, since the back side insertion groove 213 is provided on the back side surface 23 of the plate member 2, this back side insertion groove 2
By fitting the inner projecting portion 323 of the joining member 3 to 13, it is possible to prevent rainwater or the like from flowing from the mounting recess 34 to the back side surface 23 of the tip portion 24 of the plate member 2. Therefore, the water blocking effect can be enhanced.
