Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for constructing an externally insulating outer wall in which an outer wall material is attached to the outer surface of a base material via a heat insulating board.

[Conventional technology]

Conventionally, exterior wall materials were installed by interposing thin asphalt felt paper or foamed resin sheets on the surface of the base material, but this was to ensure waterproofness, and internal insulation was mainly used for insulation.

However, in recent years, external insulation has been required to improve the insulation efficiency of buildings, and in addition to or in place of the above-mentioned asphalt paper, foamed resin boards with a thickness of 20° to 200° C., rock External insulation methods have become widely used in which external wall materials are attached using elastic insulation boards such as wool boards and glass fiberboards.

Conventionally, the above-mentioned thick heat insulating board is installed by fixing asphalt felt paper, etc. with a stable using a tanker, etc., and using screws, etc. from the outer surface. As shown, insulation board 1
is interposed between them, and is attached to the base material 2 using screws 4 or the like.

[Problem that the invention seeks to solve]

By the way, if such an installation is carried out by law, the heat insulating board 1 having elasticity as described above is lightweight, so almost no load is applied to the thin screws 4, etc., so almost no bending stress is applied, but the outer wall material 3 is made of concrete, etc. It is usually heavy and the load placed on screws, etc. is large. In addition, since it is supported across the thickness of the heat insulating board 1, the bending moment applied to the head of the sibis etc. due to the weight of the outer wall material 3 is large. However, it is difficult to maintain the initial installation condition, and it is inevitable that the screws etc. will be bent, the outer wall material 3 will sag, and the relative positions of the outer wall material 3 and the heat insulating plate l will shift.

In view of the above circumstances, it is an object of the present invention to provide a method for constructing an externally insulated external wall that allows external wall materials to be firmly attached to the outer surface of the base material for a long period of time via elastic heat insulating plates. do.

[Means for solving problems]

The present invention has been made to achieve the above objects,
The gist is that in the method of constructing a #I exterior wall, in which the exterior wall material is attached to the outer surface of the base material using screws, etc. through an elastic insulation board, through-holes are drilled at the positions of the screws, etc. of the insulation board. Then, a rigid cylindrical body whose height is not greater than the thickness of the heat insulating plate and has an inner diameter larger than the diameter of the screws, etc. is inserted into the through hole, and the screws, etc. are passed through the cylindrical body. A method of constructing an externally insulating outer wall includes attaching the outer wall material to the base material via the heat insulating board.

[Effect]

In the present invention, even if a bending moment is generated by the outer wall material, the force is supported by the rigid cylindrical body due to the above-described construction method. In other words, even if the external wall material is bent due to the bending moment due to its own weight, the external wall material is supported by the rigid cylindrical body and the screws, etc. do not deform, and since the rigid cylindrical body exists, even if the screws, etc. The heat insulating material is not compressed below the length of the cylindrical body. In other words, the screws etc. do not bend, and the heat insulating board and base material of the outer wall material are in close contact, so that the outer wall material does not shift in position.

The present invention will be explained below with reference to Examples.

〔Example〕

1 and 1 show an embodiment of the method of constructing a section #I outer wall according to the present invention, and the same parts as those in the first figure are given the same reference numerals and the explanation thereof will be omitted.

Reference numerals 5 in the figure indicate through holes drilled at positions where screws 4 of the heat insulating plate 1 are inserted. A rigid cylindrical body 6 having a height not greater than the thickness of the heat insulating plate 1 and an inner diameter larger than the diameter of the screw 4 is inserted into each of the through holes 5.

To attach the external wall board 3 to the J base material 2, which usually has asphalt felt 8 or the like on the surface as a waterproof layer, with the heat insulating board 1 in between, insert the screws 4 from the surface or real part of the external wall material 30.
The rigid cylindrical body 6 inserted into the through hole 5 is passed through and fixed to the base material 2. In the external heat-insulating outer wall constructed in this way, both ends of the rigid cylindrical body 6 are pressed and sandwiched between the outer wall material 3 and the base material 2, and the heat-insulating boardwork is supported by the thick rigid cylindrical body 6. In addition, the outer wall material 3 is in a state of pressing the rigid cylindrical body 6 due to the tension of the screws 4, so the outer wall material 3 is supported by the rigid cylindrical body 6 and the screws 4, and the outer wall material's own weight is The screw will not bend due to the moment caused by the screw.

Therefore, the outer wall will not be displaced over time, and the outer wall material 3 will not fall off.

Further, FIGS. 3(a) and 3(b) show another example of the construction method according to the present invention, in which the lower edge 7a has a shape that follows the retaining part of the outer wall material 1, for example, the actual structure. Attach flat metal fitting 7 to screw 4
The rigid cylindrical body 6 inserted into the through hole 6 of the heat insulating plate l is fixed to the base material 2 (with asphalt felt 8 for waterproofing on the surface as necessary), and the lower edge of this flat metal fitting 7 is attached to the outer wall material. 3 was attached to form the exterior wall of treatment #I. In this case as well, the flat metal fitting 7 is locked by pressing both end faces of the rigid cylindrical body with 6Ω by the tension of the screw 4, almost independently of the heat insulating plate 1. Deformation, displacement of the outer wall, and falling off of the outer wall material 3 are prevented.

In the above description, the outer wall materials 1 are engaged with each other as a real structure, but the present invention is not limited to this, and it can also be used in other engagement structures such as mutual engagement. Furthermore, it can be used not only when the exterior wall material is oriented horizontally, but also when it is oriented vertically.

〔effect〕

As described above, in the method for constructing an external heat-insulating external wall according to the present invention, even when the external wall material is fixed away from the outer surface of the base, it is supported by a rigid cylindrical body whose both end faces are pressed by screws etc. Therefore, it is possible to construct an externally insulated external wall that is safe and effective even if a thick insulating board is interposed, without causing the external wall material to be displaced or fall off due to bent screws.
