Description

  The present invention relates to a double wall construction structure. More specifically, the present invention relates to a double wall construction structure comprising a base panel fixed to a body and an exterior panel attached to the base panel.

Conventionally, the exterior of a building made of concrete is usually pasted with a base material such as ALC board, PC board, or gypsum board on the concrete body, and attached with exterior materials such as metal siding or ceramic siding. This is done by using a double wall structure. As a structure of this double wall, it is generally performed by fixing a trunk edge to the base material and attaching an exterior material to the trunk edge. For example, an ALC panel is used as a base panel, and an exterior panel such as metal siding is attached to the base panel via a trunk edge to form a double wall structure. At this time, since the joint of the ALC panel becomes the joint, the width of the ALC panel becomes the joint pitch of the base panel. On the other hand, the joint of the exterior panel has the joint pitch as the width of the metal siding.

  By the way, when the width of the metal siding is different from the width of the ALC panel, the joint pitch phases may coincide and the joints may overlap each other. At this time, since the contact area between the V-shaped joint of the ALC panel and the trunk edge disposed on the joint is reduced and the mounting becomes unstable, there is a problem that it is difficult to hold the metal siding at a predetermined strength. . In addition, when the width of the base panel and the exterior panel is the same and the width is relatively wide, there is a problem that a large number of trunk edges are required to prevent the exterior panel from being bent or bent back. The present invention solves such a problem, and allows the exterior panel to be securely attached to the foundation panel via the trunk edge, even if the phase of the joint pitch between the foundation panel and the exterior panel is different or the same. The problem is to provide a double wall construction structure that can be made.

The present invention has been devised to solve the above-described problems, and has the following technical means. That is, according to the present invention, a double wall construction structure for supporting a base panel and an exterior panel arranged in parallel, the construction structure includes a trunk edge and a joint between the base panel and the exterior panel. The joint insertion member is a double-wall construction structure having a leg portion inserted into the joint of the base panel and a holding portion that receives the exterior panel in parallel, with the insertion member interposed. The base panel and the exterior panel are arranged in the same direction, and only the joint where the joints of the base panel and the exterior panel overlap, the leg portion of the joint insertion member is inserted into the joint of the base panel, and the joint insertion member holding portion A double wall construction structure characterized by receiving joints of an exterior panel is provided.

When the joint pitch between the base panel and the exterior panel is different, a body edge is interposed in the joint of the exterior panel where the joints of the base panel and the exterior panel do not overlap, and only the joint where both joints overlap is a joint insertion member It is preferable that the leg part of the outer panel is inserted into the joint of the base panel and the joint of the exterior panel is received by the holding part.

  When the joint pitch between the base panel and the exterior panel is the same, the joints are arranged so that the joints overlap with each other, and a trunk edge is interposed at the substantially central portion in the width direction of the base panel. It is preferable that the leg portion of the joint insertion member is inserted into and the joint of the exterior panel is received by the holding portion.

Preferably, the joint insertion member is made of a steel plate, and the leg portion is fixed to the joint of the base panel by a fixing means such as a nail or a screw. Moreover, it is a double wall construction structure that supports the base panel and the exterior panel arranged in parallel, and the construction structure interposes the trunk edge and the joint insertion member between the base panel and the exterior panel. In addition, the joint insertion member is a double-wall construction structure having a leg portion inserted into the joint of the base panel and a holding portion that receives the exterior panel in parallel, and the joint insertion member is made of a synthetic resin. In addition, it is preferable that the leg portion includes a piercing portion.

  The invention according to claim 1 is as described above, and in particular, since the joint insertion member has a leg portion that is inserted into the joint of the base panel and a holding portion that receives the exterior panel in parallel. It is interposed between the panel and the exterior panel, reduces the load on the trunk edge that holds the exterior panel, improves the construction quality, and can provide a firm double wall structure.

  When the joint pitch between the base panel and the exterior panel is different, the trunk edge is interposed, and only when the joints overlap, the legs of the joint insert member are inserted into the joint of the base panel, and the exterior is covered with the holding section. Since the joint of the panel is received, the joint insertion member serves as a trunk edge, both of them are evenly arranged, and the construction quality can be improved.

  When the joint pitch between the base panel and the exterior panel is the same, the joints are arranged so that the joints overlap with each other, and a trunk edge is interposed at a substantially central portion (width core) in the width direction of the base panel. The leg of the joint insertion member is inserted into the joint of the base panel and the joint of the exterior panel is received by the holding part, so the trunk edge interposed in the width core of the base panel prevents the exterior panel from bending and buckling In addition, the number of trunk edges for construction can be reduced and workability can be improved.

  Since the joint insertion member is made of a steel plate and the leg portion is fixed to the joint of the base panel by the fixing means, a firm double wall structure can be obtained. In addition, the joint insertion member is made of synthetic resin, and the leg portion is provided with a piercing portion, so that the piercing portion is inserted into the joint of the base panel, and the joint insertion member is fixed and firmly It can be a double wall structure.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the first embodiment of the double wall construction structure according to the present invention, an ALC panel having a width of 600 mm is used as the base panel, and a metal siding having a width of 455 mm is used as the exterior panel. FIG. 1 is a perspective view showing a state in which the joint insertion member 1 is mounted on the ALC panel 5 in the first embodiment. As can be clearly understood from FIG. 1, the joint insertion member 1 is composed of a leg portion 11 that is inserted into the joint 51 of the ALC panel 5 and a holding portion 12 that receives the metal siding 6 described later in parallel, and penetrates the leg portion 11.
