[Prior art]

 In recent years, in buildings, high insulation and airtightness have become widespread from the viewpoint of improving habitability and energy saving, while pillars, beams, panels, etc. have been introduced from the viewpoint of streamlining and labor saving at the time of construction. Metal fastening devices have been widely used for fastening. As for the problem of dew condensation due to airtightness of adiabatic, in general heat insulation parts where insulation materials are continuous, measures to prevent dew condensation taking into consideration moisture-proof layers, ventilation layers, etc. have come to be considered. No attention has been paid to the problem of condensation due to the heat bridge of the equipment part.

[0003]

[Problems to be solved by the invention]

 However, it is important to prevent dew condensation on the metal part for fastening by the heat bridge in order to achieve high heat insulation and airtightness. In particular, it is important to prevent condensation due to the heat bridge of metal objects such as bolts that penetrate the inner and outer surfaces from the viewpoint of durability of structural materials such as columns and beams.

An object of the present invention is to provide a heat insulating binding material for construction for preventing dew condensation due to a heat bridge of a metal fastening device and a device binding material.

[0005]

Means for Solving the Problems As a result of various studies for solving the above-mentioned problems, the present inventor has found that a heat insulating bridge of a fastening device and a fastening device of the fastening device can be obtained by using a specific heat insulating binding product. The inventors have found that dew condensation is prevented, and have completed the present invention.

That is, the present invention is a bolt- or screw-shaped heat insulating and binding material for construction, in which both ends are made of metal and the shaft middle part is made of plastic. According to the present invention, the intermediate portion of the bolt-shaped or screw-shaped binding material is made of plastic so that thermal conduction between both ends can be suppressed and dew condensation can be prevented by the heat bridge, and the bolt-shaped or screw-shaped binding material can be prevented. By using a metal for the head, neck, and other end of the metal member, it is possible to ensure the strength for supporting the stress of the fastening device or the like that is tightly connected with the bolt-shaped or screw-shaped metal member.

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described with reference to the drawings. FIG. 1 is a vertical sectional view of a bolt-shaped heat insulating and binding material of the present invention (hereinafter sometimes abbreviated as a bolt-shaped metal object). Here, 1 is a metal end portion having a bolt-shaped head portion (hereinafter sometimes abbreviated as a bolt-shaped metal portion), 2 is a metal end portion having a nut mounting portion (hereinafter abbreviated as a nut-side metal portion) 3 is a metal projection for fixing (hereinafter sometimes abbreviated as a metal projection), and 4 is a plastic shaft intermediate part (hereinafter sometimes abbreviated as a plastic part).

The bolt-shaped metal fitting is one in which a bolt-shaped metal portion and a nut-side metal portion are fitted and fixed to a plastic portion through a metal protrusion so that they can be fixed as needed at the time of fitting. An adhesive may be used.

Although the shape of the bolt-shaped metal portion is not particularly limited, it is usually rod-shaped, and a metal bolt-shaped head portion at one end, a neck portion that supports the stress of the fastening device, and the other end portion. It has a middle part plastic and a protrusion for strengthening the fixing. In addition, the length and the shaft diameter of the bolt-shaped metal portion are usually 15 to 100 mm and 5 to 25 mm, respectively. The shape of the metal part on the nut side is not particularly limited, but it is usually rod-shaped, and the metal nut mounting part and the shaft part that supports the stress of the fastening device, the intermediate part plastic, and the fixing are firmly established. It has a projection for making it. The length and shaft diameter of the nut side metal part are usually 15 to 100 mm and 5 to 25 mm, respectively. Further, examples of the metal material include stainless steel, brass, iron, copper and the like.

The length of the metal neck portion is preferably larger than the thickness width of the supporting member, and is preferably about three times or more the thickness of the fastening device. In addition, it is desirable that the nut mounting side also secures a length according to the above inside the nut mounting surface as a portion that supports the fastening device. As a guideline for the length of the protrusion for fixing with the middle plastic, use the shaft diameter dimension of the plastic part or more as a guide, and for the shape, not only the rod-shaped protrusion but also the shape that narrows toward the end and cross shape etc. Good. The surface may be uneven.

The shape of the plastic part is not particularly limited, but is usually rod-shaped, and the length and the shaft diameter thereof are usually 15 to 100 mm and 5 to 25 mm, respectively. Further, as the material of the plastic part, thermosetting resin such as epoxy resin, phenol resin, melamine resin, thermoplastic resin such as polycarbonate resin, polyester resin, nylon resin, FRP reinforced with glass fiber, carbon fiber, etc. Examples of the composite resin material include

FIG. 2 is a vertical cross-sectional view of a screw-shaped heat insulating and binding material of the present invention (hereinafter sometimes abbreviated as a screw-shaped metal object). Here, 5 is a metal part, 3 is a metal protrusion, and 4 is a plastic part. The configuration of the screw-shaped hardware is similar to that of the bolt-shaped hardware.

FIG. 3 is a cross-sectional view when the bolt-shaped metal fitting shown in FIG. 1 is used with a fastening device used for connecting and fixing columns and beams in a wooden house, for example. The bolt-shaped hardware 6 is fitted through the holes formed in the column 8 and the beam 9 with the fastening device 7 interposed therebetween, and the column and the beam can be tightly fixed by closing the bolt.

FIG. 4 is a side view of the usage example of FIG.
