By the way, Patent Document 1 does not disclose what kind of configuration the fixture for attaching the exterior material to the structure is. On the other hand, Patent Document 2 discloses a fitting that engages with the upper end portion and the lower end portion of the exterior material. The shape of this fixture itself is not very complicated. However, in order to firmly attach the exterior material to the structure using this attachment, it is necessary to provide protrusions or the like for engaging with the attachment on the upper end and the lower end of the exterior material. The shape of the upper end portion and the lower end portion of the exterior material becomes complicated. As a result, the thickness of the exterior material increases, which may hinder the weight reduction of the exterior material. In addition, foreign matter such as rainwater, insects, and dust invades the first and second holes forming the through holes via the gap between the first end face and the second end face of the exterior materials adjacent to each other in the horizontal direction. There is a risk.

The present invention has been made in view of the above-mentioned conventional circumstances, and can realize weight reduction of the exterior material, strong attachment of the exterior material to the structure, and openings in the first and second end faces of the exterior material. It is an issue to be solved to provide a fixture capable of preventing foreign matter from entering the first and second holes.

A plate-shaped extending portion arranged between the vertical joints formed by the second end surface of the second exterior material, and
A first protruding portion provided in the extending portion, protruding from the extending portion, and inserted into the first hole of the first exterior material, and a direction opposite to the first protruding portion from the extending portion. A plurality of inserts having a second protrusion that protrudes toward the second exterior material and is inserted into the second hole of the second exterior material.
A plate-like structure that extends from one side and the other side of the substrate portion to the extension portion in the same direction as the extension portion and extends in the longitudinal direction of the substrate portion facing the extension portion. A pair of support portions that are members and are in contact with the back surfaces of the first exterior material and the second exterior material on both sides of the joint portion in the vertical direction.
With
The distance from the fixing surface to the tips of both support portions is longer than the height of at least one head of a screw and a nail for fixing the substrate portion to the structure, and the first exterior material and the second exterior material and the second. A ventilation layer can be formed between the back surface of the exterior material and the structure, and the ventilation layer can be formed.
The insert is provided at a position distant from the tip of the support portion with respect to the substrate portion.

In the fixture in the exterior structure of the present invention, the first exterior material and the second exterior material are attached to the structure so as to be adjacent to each other by the substrate portion, the extending portion, and the plurality of inserters having the above-described configuration.

<Effect>
In the fixture 10 of the first embodiment, as shown in FIGS. 9 and 10, the first outer wall plate 2A1 and the second outer wall plate 2A2 are formed by the substrate portion 16, the extending portion 11, and the plurality of inserts 15 having the above configuration. And are attached to the structure 8 so as to be adjacent to each other in the horizontal direction.

At this time, the first protruding portion 15L of each insertion body 15 is inserted into each of the first holes 28R that opens in the first end surface 29R of the first outer wall plate 2A1. Further, the second protruding portion 15R of each insertion body 15 is inserted into each of the second holes 28L that opens in the second end surface 29L of the second outer wall plate 2A2. As a result, the outer surfaces of the first and second protrusions 15L and 15R and the inner surfaces of the first and second holes 28R and 28L come into contact with each other, so that the first outer wall plate 2A1 and the second outer wall plate 2A2 are in the vertical direction. , And displacement in the indoor and outdoor directions is prevented.

Further, as shown in FIG. 10, the extending portion 11 is arranged between the first end surface 29R of the first outer wall plate 2A1 and the second end surface 29L of the second outer wall plate 2A2. Such contact between the extending portion 11 and the first and second end faces 29R and 29L can prevent the first outer wall plate 2A1 and the second outer wall plate 2A2 from being displaced in the horizontal direction, that is, lateral displacement.

Further, as shown in FIGS. 7 to 10, the fixture 10 does not engage with the upper end portion 2U and the lower end portion 2D of the outer wall plate 2. Therefore, since the shapes of the upper end portion 2U and the lower end portion 2D of the outer wall plate 2 are not complicated, the thickness of the outer wall plate 2 does not increase, and there is no possibility that the weight reduction of the outer wall plate 2 is hindered.

Further, in the fixture 10, as shown in FIG. 10, the first and second protruding portions 15L and 15R are inserted into the first and second holes 28R and 28L, respectively, and the extending portion 11 is the first of the first outer wall plate 2A1. By filling the gap between the end face 29R and the second end face 29L of the second outer wall plate 2A2, the first and second holes 28R and 28L are closed.

Therefore, according to the attachment 10 and the exterior structure of the first embodiment, it is possible to reduce the weight of the outer wall plate 2 and to firmly attach the outer wall plate 2 to the structure 8, and also to realize the first and second end faces of the outer wall plate 2. It is possible to prevent foreign matter from entering the first and second holes 28R and 28L that open in 29R and 29L.

Further, in the fixture 10, as shown in FIG. 10, the distance L1 from the fixed surface 16A to each insert body 15 is between the back surfaces 2B of the first and second outer wall plates 2A1 and 2A2 and the structure 8. Since the size is set so that the ventilation layer B1 can be formed, the ventilation layer B1 can be easily secured. The length of the ventilation layer B1 in the indoor / outdoor direction is preferably about 7 mm or more.

Further, in the fixture 10, the pair of support surfaces 13L and 13R formed on the substrate portion 16 can support the back surfaces 2B of the first and second outer wall plates 2A1 and 2A2 with a simple configuration, so that the construction can be performed. It will be easy. Further, since the first and second outer wall plates 2A1 and 2A2 are stable in a state of being attached to the structure 8, the first and second outer wall plates 2A1 and 2A2 can be more firmly fixed to the structure 8.

Further, in the fixture 10, the distance L0 from the fixed surface 16A to both support surfaces 13L and 13R is the ventilation layer B1 between the back surface 2B of the first outer wall plate 2A1 and the second outer wall plate 2A2 and the structure 8. Is set to a size that can be formed. Thereby, the desired width of the ventilation layer B1 can be secured while supporting the back surfaces 2B of the first and second outer wall plates 2A1 and 2A2 by the support surfaces 13L and 13R. Therefore, it is possible to construct the outer wall plate 2 having a high accuracy of the width of the ventilation layer B1.

Further, in this exterior structure, as shown in FIGS. 2 to 5, each outer wall plate 2 includes a front side left and right joint portion 21, a back side left and right joint portion 22, a front side upper and lower joint portion 23, and a back side upper and lower joint portion 24. It is a plate material that has a so-called "four-sided fixed structure". Then, as shown in FIG. 1, the left and right joints 26 and the upper and lower joints 25 formed by overlapping the front left and right joints 21, the back left and right joints 22, the front upper and lower joints 23, and the back upper and lower joints 24 are horizontal. Gap between outer wall plates 2 adjacent to each other in the direction and the vertical direction is unlikely to occur. Therefore, it is possible to prevent rainwater from entering the back surface 2B side of the outer wall plate 2. Further, as shown in FIGS. 9 and 10, the extension portion 11 of the fixture 10 is covered by the front left and right joint portions 21 of the second outer wall plate 2A2, so that the extension portion 11 is not exposed on the surface 2F side of the outer wall plate 2. Therefore, it is possible to prevent the outer wall plate 2 from spoiling the aesthetic appearance when it is attached to the structure 8.

Further, in this exterior structure, as shown in FIGS. 3 and 4, in each outer wall plate 2, each first hole 28R and each second hole 28L have a one-to-one correspondence with each other in the left-right direction. ing. As a result, since the first and second holes 28R and 28L form a plurality of communication holes, the weight of each outer wall plate 2 can be further reduced.
