Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement of an exterior material that is used as a member for the exterior of the outer wall of a building and allows ventilation on the back side.

[Background technology] Conventionally, ventilation grooves are provided in a grid pattern on the back side of board materials.
It is known that when plate materials are stacked on the surface of an exterior wall base material, ventilation can occur through lattice-shaped ventilation grooves to prevent condensation from forming.
However, in the conventional example described above, the ventilation grooves were simply provided on the back side of the plate material, so the thickness of the plate material was different between the part of the plate material where the ventilation grooves were provided and the part other than the ventilation grooves (in other words, the thickness of the plate material was different from the part where the ventilation grooves were provided). (thickness is thinner than other parts), therefore,
There was a problem that the part where the ventilation groove was provided was weak in strength and easily damaged. For this reason, it is possible to increase the strength of the ventilation grooves by increasing the overall thickness of the board, but the thicker the overall thickness of the board, the thicker the part where the ventilation grooves are provided, which increases the strength. However, in this case, there is a problem that the overall wall thickness becomes thicker than necessary, which increases the cost, and the overall weight also increases, making it difficult to handle during transportation, construction, etc.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to provide an exterior that can strengthen the part where the ventilation grooves are provided, so that the ventilation grooves are less likely to be damaged. We provide materials.

[Disclosure of the Invention] The exterior material of the present invention is provided with ventilation grooves 3 in a lattice pattern on the back surface 2 of the board 1, and ventilation grooves 3 on the front surface 4 of the board 1.
The protrusion 5 and the plate material 1 are provided at locations corresponding to the protrusions 5 and the plate material 1, and a fitting convex portion 6 is provided protrudingly at one end of the plate material 1, and the fitting convex portion 6 of the adjacent plate material 1 is fitted to the other end of the plate material 1. Fitting recess 7
By adopting such a configuration, the above-mentioned object of the present invention is achieved. In other words, in the present invention, plate material 1
By providing the protrusions 5 integrally with the plate material 1 at locations corresponding to the ventilation grooves 3 on the surface 4, the portions of the plate material 1 where the ventilation grooves 3 are provided are reinforced by the protrusions 5, and the ventilation grooves 3 Although the protrusions 5 are provided to increase the strength of the areas where the ventilation grooves 3 are provided, the surface 4 is only formed in the areas corresponding to the ventilation grooves 3. Since the protrusion 5 is provided in a protruding manner, unnecessary portions are not made thicker, the cost is reduced, and the weight is relatively light, making it easier to handle. Also, the surface 4 of the plate material 1
By providing the protrusions 5 on the exterior material A, the protrusions 5 form a three-dimensional pattern, thereby increasing the commercial value of the exterior material A.

The present invention will be explained in detail below with reference to Examples. Exterior material A
This is constructed by providing ventilation grooves 3 on the back surface 2 of the plate 1 and protruding protrusions 5 from the front surface 4 of the plate 1 integrally with the plate 1. The exterior material A is, for example, ceramic-based, but is not necessarily limited to ceramic-based materials. The ventilation grooves 3 have a grid shape, for example, as in the embodiment shown in the drawings, and communicate in the left-right direction and the up-down direction, so that ventilation can be carried out in the left-right direction and the up-down direction in the constructed state. The protrusion 5 that protrudes from the surface 4 of the plate 1 integrally with the plate 1 is
It is provided protrudingly in part or all of the area corresponding to the ventilation groove part 3 on the surface 2 of the plate material 1. In the embodiment shown in the drawings, a protrusion 5 is provided in a part of the surface 2 of the plate 1 corresponding to the ventilation groove 3. Here, protrusion 5
It is preferable that the protruding thickness is equal to the depth of the ventilation groove 3. A fitting convex portion 6 is provided at one end of the plate 1, and a fitting concave portion 7 is provided at the other end of the plate 1. In the above embodiment, an example was shown in which the ventilation grooves 3 were shaped like a grid to allow ventilation in the horizontal and vertical directions during construction of the exterior material A, but the invention is not necessarily limited to this. , only the ventilation grooves 3 communicating in the vertical direction may be provided, or only the ventilation grooves 3 communicating only in the left-right direction may be provided. In this case as well, the protrusions 5 formed integrally with the plate 1 on the surface 4 of the plate 1 are provided at locations corresponding to the ventilation grooves 3.

However, the exterior material A having the above structure is layered on the surface side of the building's exterior wall base material 8 and is fixed using fixing tools such as nails or mounting hardware, and the exterior material A and the exterior material A is for fitting and connecting the fitting protrusion 6 and the fitting recess 7. Here, although not shown, it is preferable to interpose a preventive sealing material at the fitting portion between the fitting protrusion 6 and the fitting recess 7.
Exterior material A is applied to the building's exterior wall base material 8 as described above.
When the exterior material A is applied in layers, ventilation can be achieved through the ventilation grooves 3 provided on the back surface 2 of the exterior material A.
In this case, the ends of the ventilation grooves 3 at the ends of adjacent exterior materials A are constructed so as to communicate with each other.

[Effects of the invention] In the present invention, as described above, the ventilation grooves are provided in a lattice pattern on the back side of the board material, so the existence of the lattice-shaped ventilation grooves allows ventilation of the back side of the exterior material in the construction state. Not only can condensation be prevented from forming on the back side of the exterior material, but the protrusions are provided integrally with the board material at locations corresponding to the ventilation grooves on the surface of the board material, so that the parts of the board material where the ventilation grooves are provided can be Although the protrusion can be reinforced and the strength of this area can be increased, and the protrusion is provided to strengthen the area where the ventilation groove is provided, the area corresponding to the ventilation groove is Since the protrusions are provided on the surface, unnecessary parts are not made thicker, the cost is reduced, the weight is relatively light, and it is easy to handle. In addition, by providing protrusions on the surface of the plate material,
The protrusions form a three-dimensional pattern, which can increase the commercial value of the exterior material. Furthermore, since a fitting convex portion is provided protrudingly at one end of the plate material, and a fitting concave portion into which the fitting convex portion of an adjacent plate material is fitted is provided at the other end of the plate material, the fitting convex portion By fitting the plate and the fitting recess into each other, adjacent plates can be reliably connected to each other without requiring a separate connecting member.
