Description

[Detailed description of the invention] The present invention mainly improves the appearance of joints formed between the edges of adjacent exterior wall panels installed on the same plane in prefabricated houses such as unit houses. This article relates to improving the structure of the joint plates that cover them to ensure aesthetics and sealing against rainwater, etc.

The joint plate that has been used conventionally is in the form of a flat strip, and its installation involves attaching this flat strip-shaped joint plate 01 to the adjacent outer wall while covering the joint A. Board P,
It was applied to the outer surface of P and fixed to the base material B using wood screws 02, but in this case, the above-mentioned water screws 0
The heads 02A of the wood screws 02 are exposed on the surface of the joint plate 01, which not only contributes to the deterioration of the aesthetic appearance, but also the loosening of the wood screws 02 can easily cause rainwater to enter through the majority of the screws, impairing the sealing effect. It was also inadequate in terms of both aspects.

Also, in order to solve the above problem, it is possible to hold the joint board in place after driving the nails, but if you do this,
It is difficult to accurately drive nails in advance along the retaining part on the back of the joint board, and this problem becomes especially obvious in the case of long joint boards, and moreover, it is inevitable that The retaining part of the joint board is pressed against the head of the nail, but in particular when using elastic deformation for retaining, a certain amount of play is required between the exterior wall board and the joint board, and this is due to the joint plate installation. It had the disadvantage that it would remain as a gap afterwards.

The present invention has been improved to eliminate the drawbacks of the prior art, and involves associating the joint plate and the nails that are inseparable from the joint plate, so that they can be integrated in advance. It is possible to freely adjust the positions of the nails and the joints, and can be installed accurately without spoiling the aesthetic appearance due to exposed nails or causing relative positional deviation between the nails and the joint boards. The aim is to provide a possible joint plate structure.

The characteristic configuration of the joint plate structure according to the present invention is that the joint plate is formed between the edges of adjacent exterior wall boards and is placed on the back side of the joint plate that covers the joint plate along the longitudinal direction of the joint plate and perpendicular to the longitudinal direction of the joint plate. A pair of elastic protrusions are provided protrudingly facing each other at an appropriate interval in the width direction, and the protruding ends of both elastic protrusions are bent toward the side closer to each other than the opening side. A groove with a wide bottom side is formed, and the nail attached to the joint plate has a disk-shaped head with a diameter smaller than the bottom width of the groove and larger than the opening width of the groove. and a distance corresponding to the distance between the bottom of the groove and the opening edge from the top surface of the head, the short diameter part is set smaller than the opening width of the groove, and the long axis An oval flange portion having a width larger than the opening width of the groove is provided, and the top surface of the nail is in contact with the bottom of the groove of the joint board, and the oval flange portion is set to be larger than the opening width of the groove. The structure is such that it is attached to the joint board between the edges of the opening, and the following effects can be expected from this configuration.

In other words, the nails used to fasten the joint board to the base material are fixed and held on the back side of the joint board, and their heads are not exposed on the surface at all, so there is no loss of aesthetic appearance during construction, and the design is improved. You can improve your performance.

Furthermore, since the joint plate has no through holes on its front and back surfaces, the sealing effect is also great.

In addition, since a groove is formed on the back side of the joint board that spans the entire length in the longitudinal direction, it is possible to insert and lock the required number of nails into this groove, and fastening requires precision in the pitch of the tools. figure,
For example, it can be manufactured at low cost by simply extruding resin or aluminum, and has the advantage of increasing the rigidity of thin joint plates.

In particular, the present invention achieves this effect by fixing and holding the nails on the back side of the joint board in advance without causing various technical problems caused by the above-mentioned structure in which the joint board is engaged and held after the nails are driven. It was something I was meant to get.

Hereinafter, an embodiment of the present invention will be described in detail based on FIGS. 1 to 3. As shown in FIG. 1, on the back side of the joint plate 1,
A pair of elastic protrusions are provided along the longitudinal direction of the joint plate 1 along the entire length of the joint plate 1, and are opposed to each other at an appropriate small interval in the width direction perpendicular to the longitudinal direction. The pieces 3A, 3A are provided, and the elastic protruding pieces 3A, 3 are further provided.
By bending the protruding ends of the elastic protrusions 3A in a direction in which the protruding ends thereof approach each other, a groove 3 in the shape of a deep floor is formed, which is wider on the bottom side than on the opening side.

The nails 2 attached to this joint plate 1 and capable of being driven into the base plate B have a diameter slightly smaller than the bottom width of the groove 3 of the joint plate 1 and wider than the opening width of the groove 3. A head 2A formed in the shape of a disk with a sufficiently large diameter is provided, and the top surface of the head 2A is brought into contact with the bottom of the groove 3 on the side closer to the tip of the head 2A. In this state, the groove 3 is positioned at a distance corresponding to the distance between the bottom of the groove 3 and the opening edges 3a, 3a from the top surface so as to be in contact with both opening edges 3a, 3a of the groove 3. , is provided with an oval flange portion 2B whose minor diameter is slightly smaller than the opening width of the groove 3 and whose major diameter is slightly larger than the opening width. The fitting is inserted into the groove 3 of the joint plate 1 from the longitudinal end of the joint plate 1 so that the top surface of the joint plate 2A is in contact with the bottom of the groove 3 and the oval flange part 2B is sandwiched between the opening edges 3a, 3a. By rotating the nail 2 by 90° in the fitted and locked state, the long diameter portion of the substantially oval flange portion 2B formed in series with the head portion 2A of the nail 2 is bent on both left and right sides by the bent portions of the protrusions 3A, 3A. The nail 2 is configured such that it can be clamped and held fixed at any position.

These are integrally formed by extrusion molding of resin or aluminum, and a desired number of nails 2 are inserted and locked into the grooves 3 on the back surface of the joint plate 1, and the grooves 3 are With sealing materials 4, 4 affixed to the back surfaces of both sides, the joint plate 1 is positioned corresponding to the outer surface side of the joint A formed between the edges of the adjacent exterior wall panels P, P. Then, by driving the nails 2 into the base material B using a hammer or the like from the surface side of the joint board 1, a pair of elastic protrusions 3A forming the grooves 3 are formed, as shown in FIGS. 2 and 3. ,3
A into the joint A, and sealing material 4.4 on both sides.
The joint treatment is performed with the outer wall panels P, P brought into close contact with the outer surfaces of the panels P.

In addition, C2C in the figure is a nail for attaching the adjacent exterior wall boards P, P to the base material B.

Further, the foot portion of the nail 2 is provided with a protrusion 2C for rotating the nail and for resisting removal after driving.
