Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fastener for a heat insulating wall material.
[0002]
[Prior art]
Conventionally, as an outer wall structure of a building, a heat insulating wall in which a heat insulating layer is provided on the back surface of the wall plate is known.
[0003]
As a method of constructing these heat insulating walls, generally, a plate-like heat insulating material made of foamed plastic molding, glass wool mat, or the like is fixed to the wall base material at the body edge, and then the exterior wall material is attached to the surface of the body edge with nails or the like. There are a method of fixing with a metal fitting or the like, and a method of using an outer wall material with a heat insulating plate affixed to the back surface and fixing it to a wall base material with a nail or a mounting metal fitting.
[0004]
However, the former construction method using the trunk edge has a problem that the trunk edge is likely to be uneven due to the difference in the compression ratio of the thermal insulation material because the trunk edge is driven and fixed from the surface of the thermal insulation material.
[0005]
In addition, there is a problem that it takes time for construction such as construction of a heat insulating material, sashing of the trunk edge, and affixing of an outer wall material.
On the other hand, when using the outer wall material with the latter heat insulating material attached, there is an advantage that the work of the heat insulating layer and the outer wall material can be completed at once if the outer wall material is attached to the wall base, but the work of the work can be saved. Since the heat insulation layer is laminated and integrated, a necessary ventilation space cannot be secured between both layers, and there is a problem that a separate moisture-proof measure is required.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to solve the above problems and easily construct a heat insulating wall having a sufficiently large heat insulating space between an outer wall material and a heat insulating layer.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, in the clasp for a heat insulating wall material according to claim 1, a wall material support plate is extended from a substrate surface fixed to a wall base surface, and the substrate is provided on the front and back surfaces of the substrate. A pair of positioning members are provided that are provided with a locking piece for positioning the heat insulating material applied to the surface, and are engaged with the end portion of the outer wall member with a necessary space width from the positioning locking piece to the front end side of the support plate. A locking piece is provided upright on the support plate.
[0008]
That is, since the heat insulating material and the outer wall material are configured to be attached to one metal fitting with a necessary heat insulating space therebetween, a heat insulating wall can be constructed by fixing one type of metal fitting, and the construction becomes easy.
[0009]
Moreover, since the heat insulation space is surely formed in the heat insulation wall, it has an effect on dew condensation.
Further, since the metal fitting can be directly fixed to the wall base surface, the problem of unevenness such as when fixed on a heat insulating material is eliminated.
[0010]
According to a second aspect of the present invention, there is provided a heat-insulating wall material fastener according to the first aspect of the present invention, wherein the heat-insulating wall material fastener according to claim 1 is an elongated body that continues along the wall base surface. In addition, a vent hole penetrating the upper and lower surfaces of the support plate is provided.
[0011]
When the mounting bracket is a long body that is attached to the full width of the wall surface, air circulation in the heat insulating space is achieved through a through hole formed in the support plate.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, a description will be given of a clasp for a heat insulating wall material according to an embodiment of the invention.
Embodiment 1
FIG. 1 is a perspective view of a heat insulation wall fastener according to Embodiment 1, and FIG.

Then, the heat insulating material 3 made of foamed resin or the like is installed between the base surface 10 and the locking piece 12, and then the outer wall material 4 such as a fiber reinforced cement board is installed on the locking pieces 13 and 14.
[0017]
The illustrated outer wall material 4 is formed with joining step portions 4a and 4b which are fitted to each other at the upper and lower edges, the locking piece 13 is in contact with the back surface of the outer wall material 4, and the locking piece 14 is in the joining step portion. It engages with the fitting groove 4c formed in the above.
[0018]
When the lower ends of the heat insulating material 3 and the outer wall material 4 are installed and positioned as described above, the fasteners 1 of the heat insulating wall material are applied to the upper end portions of the heat insulating material 3 and the outer wall material 4, and the base plate 10 is fixed to the wall base surface 2 with a fastener such as a nail. 7 to fix.
[0019]
In this way, the heat insulating material 3 and the outer wall material 4 are sequentially fixed. At this time, a gap with a width S is formed between the outer wall material 4 and the heat insulating material 3, which becomes a ventilation space 8 over the entire wall surface, so that condensation within the heat insulating wall is prevented and even if condensation occurs, ventilation To dry quickly.
[0020]
Therefore, according to the clasp 1 of the heat insulating wall material, the heat insulating wall having the ventilation space 8 between the heat insulating material 3 and the outer wall material 4 can be easily constructed.
As another configuration example of the first embodiment, as shown in FIG. 3, the upper and lower edges of the locking pieces 12 and 13 are inclined surfaces 12 a and 13 a that are inclined in directions facing each other, You may make it become a guide surface of the outer wall material 4. FIG.
