Description

  The present invention relates to a structure for efficiently performing a fixing operation of a moisture permeable sheet or the like in fixing a moisture permeable sheet or the like in an external heat insulating method.

  In general, in the outer insulation method, the outer wall direction of a pillar or the like serving as a base is covered with a plate-like heat insulating material formed of a fragile foam having no stretchability. And after sealing the joint part of the said plate-shaped heat insulating material using an airtight tape, the moisture-permeable sheet to which the fixed tension was given with respect to the said plate-shaped heat insulating material is affixed so that water may not penetrate | invade the inside of a building. Attached.

  Conventionally, the said moisture-permeable sheet is affixed using the double-sided tape affixed on the surface of the plate-shaped heat insulating material.

  However, in the case of a structure using a double-sided tape, moisture permeation in a state where insufficient tension is applied, for example, the moisture permeation sheet is blown by the wind during a work in which constant tension is applied to the moisture permeation sheet. There is a case where the sheet is mistakenly adhered. At that time, the worker must carefully peel off the moisture-permeable sheet that has been given insufficient tension, which is allowed to enter water, from the double-sided tape. Become. In addition, when a worker uses a structure using double-sided tape, it is necessary to work carefully so as not to cause the above-mentioned problems, which imposes great effort on the worker, Bad structure.

  On the other hand, in order to prevent the moisture permeable sheet from being erroneously adhered during work and to improve work efficiency, staples are driven directly into the plate-shaped heat insulating material from above the moisture permeable sheet. The structure of attaching with is widely used.

For reference, a structure in which a sheet fixing base is provided between a heat insulating material and a sheet has been disclosed as shown in Patent Document 1 below. This is a method of using an adhesive in fixing the sheet.

  However, in the case of the mounting structure using staples as described above, there is a problem that if the attached moisture-permeable sheet is blown in the wind, the staples directly driven into the plate-shaped heat insulating material will come off. there were. This is because the staple is driven in a state in which the plate-like heat insulating material is crushed, and the staple is densely pressed due to the contractibility of the building material as in the case of driving into a building material having elasticity such as wood. It is because it is not pinched.

  Furthermore, when the staple is placed from the surface of the moisture permeable sheet to the plate-like heat insulating material, the plate-like heat insulating material is damaged at the time of placing the staple, and the strength of the building material is greatly impaired. It was.

  Further, the method described in Patent Document 1 has a problem that it takes a very long time for construction because an adhesive is used for fixing the sheet. Furthermore, when constructing on the wall surface, there was a problem that the adhesive dripped.

  Therefore, in view of the above situation, the object of the present invention is to reliably apply a moisture-permeable sheet or the like, which is given a certain tension, to the plate-like heat insulating material or the like even when it is blown by the wind. It is an object of the present invention to provide a structure that can be attached and does not require labor as in the case of using a double-sided tape, and does not crush the plate-like heat insulating material or the like when placing staples or the like.

Means and action for solving the problem

  In order to solve such a problem, the present invention, in the moisture-permeable sheet mounting structure of the outer heat insulation method, fixed a band-shaped body made of a stretchable soft material on the surface of the plate-like heat insulating material, An attachment structure for fixing the moisture permeable sheet with sufficient strength by driving and fixing staples from the surface of the moisture permeable sheet to a belt-shaped body made of a material is employed.

Furthermore, by interposing the strip-like body between the plate-like heat insulating material and the moisture-permeable sheet, it is possible to prevent the surface of the plate-like heat insulating material from being damaged at the time of stapling.

  It should be noted that there is no problem even if the material of the belt-like body is any material such as paper, resin or metal as long as it has an effect of gripping staples to be driven and fixed. Further, there is no problem with any shape, such as a rib in the longitudinal direction.

  In the present invention, the band-like body is fixed by using a double-sided tape or an attachment structure performed by an adhesive layer on the surface of the band-like body itself. And by fixing the said strip | belt body with the raw material which has adhesiveness, the failure | damage of the said plate-shaped heat insulating material which generate | occur | produces when it fixes using a nail, a screw | thread, etc. can be prevented.

  Furthermore, by adopting a structure in which the belt-like body is attached to the peripheral edge of the surface of the plate-like heat insulating material, when an external force such as an impact at the time of stapling is applied, the peripheral edge is damaged and missing. It can be prevented that the function of high airtightness and high heat insulation originally required in the heat insulation method for the outer covering is impaired.

The invention's effect

  According to the structure of the first aspect of the present invention, a belt-shaped body made of a soft material having elasticity is attached to the surface of the plate-shaped heat insulating material or the like, and staples or the like are attached to the belt-shaped body from the surface of a moisture-permeable sheet or the like. As compared with the case where the staples are directly driven into the plate-shaped heat insulating material, the staples and the like are sandwiched by the band-like body around which the staples are driven and are tightly pressed, thereby holding the staples. It is possible to prevent the staples from being removed from the moisture permeable sheet by being blown by the wind.

  Further, in the invention described in claim 2, in addition to the function and effect of the invention described in claim 1, the adhesive material of the band-shaped body fixes the band-shaped body to the plate-shaped heat insulating material. By having the effect, the material having adhesiveness is entangled with the surface of the staple or the like driven into the belt-like body, and the staple or the like can be adhered and held.

  That is, staples and the like are not only clamped by press-fitting into the band-like body, but are also chemically fixed by an adhesive material, and can be fixed more firmly.

  According to the invention described in claim 3, when the belt-like heat insulating material receives an external force such as an impact at the time of placing a staple or the like by attaching the belt-like body to the peripheral edge of the plate-like heat insulating material. Further, it is possible to prevent a problem that the peripheral portion is damaged or missing, and the function of high airtightness and high heat insulation that is originally required in the outer heat insulation method is impaired.

  Furthermore, according to the invention described in claim 3, when the strip is attached to the periphery of the plate-like heat insulating material, the belt is attached so as to straddle the peripheral edge of the adjacent plate-like heat insulating material. In the above, the adhesive material is used as an airtight material, that is, the band-shaped body has both adhesive and confidential properties, and the work for sealing the plate-like heat insulating material using an airtight tape And the operation | work which attaches and fixes the said strip | belt-shaped body can be performed simultaneously.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a structure of the present invention, FIG. 2 shows a strip made of a soft material, and FIG. 3 shows a cross section when staples are driven into the strip according to the present invention. FIG.

  As shown in FIG. 1, after the band-like body is attached and fixed to the peripheral edge of the plate-like heat insulating material, a moisture-permeable sheet is stuck with staples in a state where a certain tension is applied.

In that case, in view of workability when performing the construction of the moisture permeable sheet, the belt-like body shown in FIG. 2 desirably has adhesiveness only on the surface in contact with the plate-like heat insulating material, confidentiality, From the viewpoint of workability, the adhesive component is preferably formed of an adhesive component having acrylic airtightness.

  In addition, the said strip | belt-shaped body attached and fixed to the peripheral edge of the said plate-shaped heat insulating material is fixedly mounted so that it may straddle the peripheral edge of two said plate-shaped heat insulating materials, when the said plate-shaped heat insulating material is fixed side by side. Thus, since the belt-like body serves as an airtight tape, there is no problem in workability as compared with the conventional work.

  Also, as shown in FIG. 3, when the staple is driven into the strip, the staple is adhered to the adhesive and is fixed so as to be chemically integrated. Even if staples are driven into the body, there is no loss of confidentiality.

  Next, when the belt-like body is mounted and fixed across the two plate-like heat insulating materials, the plate-like heat insulating material is made stronger by driving each leg of the staple into a different plate-like heat insulating material. Can be fixed.

  Furthermore, compared with the case where staples are directly driven into the plate-shaped heat insulating material, by driving the staples into the band-shaped body, the band-shaped body, which is a soft material having elasticity, can only increase the pull-out strength of the staples. Therefore, it is possible to absorb the impact generated when the staple is struck and to prevent deformation of the plate-shaped heat insulating material.

  As a result, by preventing deformation of the plate-like heat insulating material, it is possible to prevent the plate-like heat insulating material from being damaged due to concentration of stress on the deformed portion. By doing so, the owner can enjoy high airtightness and high heat insulation, which are the merits of the external heat insulation method for a long time.

  It is the perspective view which showed the structure of this invention.   It is the perspective view which showed the said strip | belt-shaped body in this invention.   It is a cross-sectional perspective view when staples are driven into the belt-like body in the present invention.
