[Technical field to which the invention belongs]

 The present invention relates to a heat insulating fixed metal fitting for building. More specifically, the present invention relates to a pin-shaped heat insulating fixed metal fitting for construction, both ends of which are made of plastic and an intermediate portion of which is made of metal. INDUSTRIAL APPLICABILITY The insulating heat-insulating metal fixture for buildings according to the present invention is useful for preventing dew condensation due to the heat bridge of the metal fastening device and the device-fixing hardware mainly used in the heat insulating structure of a wooden structure.

[0002]

[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 fixed metal fitting for a building for preventing dew condensation due to a heat bridge of a metal fastening device and a device fixed metal fitting.

[0005]

[Means for Solving the Problems] As a result of various studies to solve the above problems, the present inventor has found that a heat-bridge of a fastening device and a fixed hardware of the fastening device can be realized by using a specific heat insulating fixed hardware. The inventors have found that dew condensation is prevented, and have completed the present invention.

[0006] That is, the present invention is a pin-shaped heat insulating fixing hardware for a building, the both ends of which are made of plastic and the shaft middle part is made of metal. According to the present invention, both ends of the pin-shaped metal object fixed to the fastening device are made of plastic, so that thermal conduction between the both ends can be suppressed and dew condensation can be prevented by the heat bridge. By using a metal as the material, it is possible to secure the strength for supporting the stress of the fastening device fixed by the pin-shaped metal.

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a pin-shaped heat-insulating fixed metal object of the present invention (hereinafter sometimes abbreviated as a pin-shaped metal object) having a rod shape. Here, 1 is a plastic end portion (hereinafter sometimes abbreviated as a plastic portion), 2 is a metal shaft intermediate portion (hereinafter sometimes abbreviated as a metal portion), and 3 is a fixing metal portion projection ( Hereinafter, it may be abbreviated as a metal protrusion).

FIG. 2 is a vertical cross-sectional view of one of the plastic parts of the pin-shaped metal article of the present invention having a bolt-shaped head.

The pin-shaped hardware is a metal part in which two plastic parts are connected and fixed by interposing them through metal protrusions, and an adhesive is used as necessary when fitting. Good.

The shape of the plastic portion is not particularly limited, but is usually rod-shaped, and one of them may have a bolt-shaped or screw-shaped head or a threaded portion at the end. . The length and the shaft diameter are usually 15 to 100 mm and 5 to 25 mm, respectively.

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, glass fiber, carbon fiber and the like are used. Examples include reinforced composite resin materials such as FRP.

The metal part is not particularly limited in shape, but is usually rod-shaped, and its length and shaft diameter are usually 15 to 100 mm and 5 to 25 mm, respectively. It is desirable to make it larger than the thickness width of the member to be attached, and it is desirable to be about 3 times or more the thickness of the fastening device. Regarding the length of the protrusion for fixing to the end plastic part, the axial diameter dimension or more should be taken as a guide, and the shape may be not only a rod-shaped protrusion but also a shape that narrows toward the end and a cross shape. Further, the surface may be uneven. Further, examples of the material thereof include stainless steel, brass, iron and copper.

FIG. 3 is a cross-sectional view when the pin-shaped metal fitting shown in FIG. 1 is used together with a fastening device used for connecting and fixing pillars and beams at indoor and outdoor boundaries in a wooden house, for example. Here, 4 is a pin-shaped metal, 5 is a fastening metal, 6 is a pillar, and 7 is a beam.

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

[0015]

[Effect of the invention]

 By using the heat insulating fixed metal fittings for a building of the present invention, it is possible to prevent dew condensation due to the heat bridge of the fastening device and the fastening hardware of the fastening device, and improve the durability of the members and the durability of the building. it can.
