Description

  This invention has a male mold on one side of an elongated rectangular unit plate made of wood such as thinned wood and a female mold on the other side. The present invention relates to an interior / exterior material that is formed respectively to form a wide plate-like body by sequentially combining a plurality of unit plate male and female dies.

Conventionally, when forming a continuous wide plate by connecting a plurality of plates as described in JP-A-61-16801, male and female ridges are respectively provided on opposite side surfaces of the plate. It is already known that many of them are already installed and fitted to each other and connected one by one to enhance the sense of unity and facilitate construction on site.
However, this conventional method is basically on-site construction, and it is necessary to combine a large number of plates one by one on the site and bond them together. The plate must be brought apart and the number of parts must be increased, and the on-site parts management is cumbersome and the work efficiency is poor.

Various means for solving the above-mentioned problems have already been considered, and the applicant of the present invention can also produce a factory, and can improve the work efficiency at the site, and one side of an elongated rectangular unit plate. A male mold is formed on the other side, and a female mold is formed on the other side surface. In a state where the male mold and the female mold are sequentially combined, a flexible material is applied to one surface of the plate-like body. We are currently proposing interior and exterior materials that are integrated into a wide plate. (JP-A-2-239904, JP-A-2-20613)
JP 61-16801 A JP-A-2-239904 Kaikai 2-20613

In the conventional method of connecting a plurality of plate bodies to form a continuous wide plate body (plate tension), even if the plate bodies are combined one by one on site, a wide plate body is produced in the factory in advance. In both cases, a male mold (zone) is formed on one side of the plate body, and a female mold (zone) is formed on the other side surface. Are combined sequentially.
Therefore, as compared with a case where a simple flat plate not subjected to kneading is abutted and pasted, a clean construction can be performed without a gap between adjacent plates.
However, wood is a living creature, and it repeatedly absorbs and discharges moisture after construction, and is slightly expanded and contracted accordingly. There are four seasons as in Japan, and the difference between the hot and humid season in summer and the dry season in winter is large, and even during close construction, there is an overlapping part due to aging (stretching) due to secular change (stretching). However, it can be said that there is no possibility that a gap occurs due to a shift occurring here, and in a severe case, the shift is greater than the overlap between the male ridge and the female ridge.
For this reason, in order to prevent the above-mentioned deviation from occurring in the plate material in spite of the fact that it is bent at the construction site where confidentiality and clean appearance are required, each sheet is used as a base. Means such as fixing with a nail or the like have been taken, and the work efficiency may not necessarily be improved.

Means to try to solve the problem

  A long and narrow rectangular unit plate (A) having a bottom surface (1) and a surface (2) which are parallel to each other as a base, a male mold is formed on one side surface, and a female mold is formed on the other side surface, and the plurality of unit plate bodies (A, A ′) A male mold (M) and a female mold (W) are combined in order to form a wide plate-like body. On the fitting surface of the female mold (W), either a male mold or a female mold has a V-shaped or trapezoidal convex portion (3), and the other has a V-shaped engagement with the convex portion, or The substantially adjacent unit plate bodies (A, A ′) were integrated by providing a trapezoidal concave portion (4) and engaging the convex portion (3) with the concave portion (4).

The invention's effect

According to the present invention, an inner / exterior material comprising a plurality of unit plate male and female molds sequentially combined with a male mold on one side surface and a female mold on the other side surface. By providing a concave portion and a convex portion that engage with each other on the mating surface of the male mold and the female die, and engaging the convex portion (3) and the concave portion (4), the engagement position between the male die and the female die is accurate. In addition, once the convex portion (3) and the concave portion (4) are engaged and fixed, the male mold and the female mold do not shift on the fitting surface.
That is, the adjacent unit plate body is restrained from moving in the vertical direction by fitting the male die and the female die, and is substantially integrated by restricting the movement in the left-right direction (plate width direction) by the engagement of the concave portion and the convex portion. Is done.

  Accordingly, even if the unit plate body is subjected to a force that causes the male mold and the female mold to deviate from each other due to deformation or expansion / contraction, the adjacent unit plate bodies substantially maintain a sense of unity with each other. Therefore, the adjacent unit plate bodies are not shifted from each other and a gap is not generated between them. In addition, since the adjacent unit plate bodies are substantially united, the unit plate bodies can be displaced from each other by a normal fixing method, for example, by simply attaching to each other, for example, by nailing every few sheets. Will not occur.

Hereinafter, it demonstrates along the Example shown in drawing.
1 to 4 show an embodiment of the present invention. FIG. 1 is a partial perspective view, FIG. 2 is a side view in which a part is bent, and FIG. 3 shows male and female dies of adjacent unit plate bodies. FIG. 4 is a partial perspective view showing a combined state (bending state) of the same male and female dies, and is a view seen from the opposite surface (back surface) of FIG.

  The plate-like body A of the present invention is made of wood such as cedar, cypress, and hiba, and in particular, it has little use in terms of economy and is not harvested or is left in the forest after harvesting. Even small trees like thinned wood can be used sufficiently, so if thinned wood is used from the viewpoint of the recent trend of nature conservation and the prevention of global warming, nature conservation and global Helps prevent global warming.

  The unit plate A is, for example, a rectangular flat plate having a width of 10 cm, a length of 1.8 m, and a thickness of 10 mm, and has a substantially parallel bottom surface 1 and surface 2. Note that the expressions of the bottom surface 1 and the surface 2 are used for convenience of explanation, and if the front and back are reversed, the bottom surface 1 and the surface 2 are reversed. Needless to say, the width, length, and thickness of the plate-like body A are merely examples, and optimal dimensions can be selected as appropriate from the intended use, raw materials (for example, raw wood), and the like.

Next, the male mold M and female mold W formed on the side surface of the unit plate A will be described with reference to FIGS.
The male mold M is formed on one side surface of the unit plate A.
On one side surface of the unit plate body A forming the male mold M, the bottom surface 1 side is approximately ½ of the plate thickness direction from the end surface of the unit plate body A by about the same length as the plate thickness. It has been cut off. Then, the uncut portion is left along an arc drawn with the line o-a connecting the cut-out bottom surface 1 side end o and the uncut bottom surface 1 side tip a as the rotation radius. The surface 2 side end is cut off. Therefore, the male mold M is formed in a substantially V-shaped projection in a side view.
On the other hand, the female mold W is formed on the other side surface of the unit plate A forming the male mold M.
One side surface of the unit plate A forming the female mold is cut from the end surface by a length approximately the same as the plate thickness, and the surface 2 side is cut off in the plate width direction of approximately 1/2 the plate thickness, contrary to the male mold M. Yes. Then, the surface cut off with a rotation radius (o′-a ′) equal to the cut-off rotation radius (oa) of the tip end portion of the male mold M, with the left side end o ′ on the bottom surface 1 side as the rotation center. The side end on the second side is cut from the surface side in the plate thickness direction and along a circular arc drawn with the side end o ′ on the bottom surface 1 side as the rotation center. Accordingly, the female mold W is formed in a concave portion that is substantially V-shaped in a side view.
Therefore, as shown in FIG. 3, in the state where the male mold M and the female mold W formed on the side end portions of the unit plate bodies A and A ′ adjacent to each other are combined, the thickness of the combined portion is also the element base of the unit plate body. It becomes equal to the plate thickness.

  Then, the V-shaped convex portion 3 as viewed from the side face the bottom surface 1 side of the male mold M, and the V-shaped convex section 3 provided on the male mold M on the front surface 2 side of the female mold W. At the position, a V-shaped concave portion 4 that engages with the convex portion 3 is provided. Therefore, the adjacent unit plates A and A ′ can be engaged and disengaged by rotating relatively with o (o ′) as a fulcrum as shown in FIG. 4, but once the engagement is made as shown in FIG. In the state that has been made, even if the force in the vertical direction and the horizontal direction (plate width direction) is applied, the movement in the vertical direction is restricted by the fitting of the male mold M and the female mold W, Since the movement in the left and right direction is restricted by the engagement of the V-shaped convex portion 3 provided on the male mold M and the V-shaped concave portion 4 provided on the female mold W, the male mold M and the female mold W does not move (displace) by fitting.

In FIGS. 1 to 4, reference numerals 5 and 6 denote chamfered portions, and a medium 7 is formed at a joint portion on the surface 2 side of adjacent unit plate bodies A and A ′. Further, it is desirable that 8 is provided as appropriate in order to absorb the distortion of the plate at the back. (The description is omitted in FIGS. 3 to 4)
Furthermore, although illustration is omitted, if a cloth or the like is lined on the bottom surface 2 with the male mold M and the female mold W fitted together, an inner / exterior material having a desired width can be integrated in that state. It can be obtained and can be folded if the backing material is a flexible material.
Furthermore, if the male mold M and the female mold W are fitted to each other by applying an adhesive in the width direction to the mating surface of the male mold M and the female mold W, it is desirable as in the case of the backing. The interior / exterior material can be obtained in a wide area. And if the intensity | strength of an adhesive agent is selected appropriately, since it can isolate | separate by bending, it is possible to adjust according to construction width, without using a cutting tool.

Next, another embodiment will be described with reference to FIGS.
Since this embodiment is basically the same as the embodiment shown in FIGS. 1 to 4, only the differences will be described.
In the embodiment shown in FIG. 5 and FIG. 6, in the above embodiment, the V-shaped convex portion 3 is formed on the side of the bottom surface 1 of the male mold M, and the male mold M on the front surface 2 side of the female mold W. Whereas the V-shaped convex portion 3 is provided at a position facing the V-shaped convex portion 3, the V-shaped concave portion 4 engaging with the convex portion 3 is provided, whereas the V-shaped convex portion 3 and the concave portion 4 are formed as trapezoidal convex portions. 3 ′ and the recess 4 ′, and the difference is that the recess 4 ′ is provided on the male mold M side and the protrusion 3 ′ is provided on the female mold W, and the surfaces of the unit plate bodies A and A ′. Although the difference is that the medallions 7 are not formed at the joints on the two sides, the basic actions and effects are the same.

In the two embodiments described above, the protrusion 3 provided on either the male or female mold is V-shaped or trapezoidal, and the other is V-shaped or trapezoidal to engage with the protrusion 3. Although the example which provided the recessed part 4 was demonstrated, this is not limited to V shape or trapezoid shape, What is necessary is just a shape which does not produce a blur in the left-right (width) direction in the engagement state.
In addition, as for the shapes of the male mold M and the female mold W, the example in which the male mold M is cut into an arc shape and the female mold W is cut into an arc shape has been described, but this is not limited to the arc shape. It may be a straight line (tangent line) that approximates an arc.
