Detailed Description of the Invention Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a perspective view of a heat insulating material for a girder according to an embodiment of the present invention,
2 and 3 are cross-sectional views of the essential parts showing the mounting state of the heat insulating material for girders, and the same members as those shown in FIGS. 6 to 8 are designated by the same reference numerals.

As shown in FIGS. 1 and 2, the girder insulation material 10 according to the present embodiment.
Is an airtight tape on the top surface of the wall heat insulating material 102a stretched around the inclined surface 14 against which the base plate 115a is pressed, the side surface 15 in contact with the eaves girder 113, and the shaft assembly 112 such as the pillar 110 and the stud 111. And a bottom surface 16 that is in direct contact with the rafter 114, and is mounted between the rafters 114.

In this embodiment, a protrusion 12 is formed on the inclined surface 14 side of the girder heat insulating material 10 so that it can be easily installed on the eaves girder 113. It should be noted that the protrusion 12 is not always necessary in the present invention.

An example of a building in which such a girder heat insulating material 10 is used is shown below.

As shown in FIG. 5, the building 100 is provided with a wall heat insulating material 102a inside the outer covering material 101, and the outer covering material 101 and the wall heat insulating material 102 are provided.
An outer ventilation layer 103 is formed between the outer layer and a.

The wall heat insulating material 102a includes a frame assembly 11 such as a pillar 110 and a stud 111.
It is stretched around the outside of 2.

On the other hand, the roof heat insulating material 102b is constructed by hanging a rafter 114 on the eaves girder 113 provided for the roof of the frame portion 112 such as the pillar 111.
A field board 115a is provided on the upper side, and is provided on the field board 115a from the eaves toward the ridge. On the roof heat insulating material 102b, a ventilation rafter 116, a field board 115b, and a roof material 117 are further provided.

In this embodiment, as shown in FIGS.
Is mounted between the rafters 114 between the base plate 115a and the eaves girder 113, and is continuous with the top of the wall heat insulating material 102a. An airtight member such as an airtight tape or an airtight sealing material may be interposed between the girder heat insulating material 10 and the wall heat insulating material. As the airtight tape, vinyl chloride resin foam, polyurethane resin foam, or the like is used.

As shown in FIG. 2, the height h of the girder heat insulating material 10 is
The height of the rafter 114 is set to be substantially the same as the vertical height. To set in this way, if the height of the girder heat insulating material 10 is made higher than the vertical height of the rafter 114, the lower end of the girder heat insulating material 10 projects downward from the rafter, and the wall heat insulating material 102a and the rafters. This is because there is a gap between them.
This is because a gap is created between the wall heat insulating material 102a and the wall heat insulating material 102a.

As the heat insulating material 10 for the girder and the heat insulating materials 102a and 102b, a synthetic resin foamed heat insulating material is preferable, and polystyrene, polyethylene, polyvinyl chloride, or another synthetic resin having an independent fine structure obtained by foaming the synthetic resin 30 to 60 times is used. Foam insulation is preferred. Among these, it is effective to use a polyethylene foam heat insulating material which is excellent in stretchability, resilience and flexibility, and has high heat insulating properties and high moisture resistance.

FIG. 3 is a horizontal cross-sectional view of a heat insulating structure for a building according to another embodiment of the present invention. In this example, the girder insulation 10
One or a plurality of V-shaped or linear slits 13 are formed on the protrusion 12 of the base plate 115a so as to be easily deformed by being pressed by the base plate 115a.
Are formed. Note that FIG. 3 shows one V-shaped slit.

A field board 115a is installed along the top of the rafter 114, and heat insulation for the girder 10
When is pressed, both upper and lower projecting pieces 12a and 12b formed on both sides of the slit 13 are elastically deformed. Therefore, even if the building has different roof angles (angles of the base plate 115), the inclination angle θ of the inclined surface 14 changes due to the pressing by the base plate 115a, and therefore the same girder heat insulating material 10 is used. It is not necessary to prepare different girder heat insulating materials 10 for different buildings.

The inclination angle θ of the inclined surface 14 is such that the roof angle of the building is 5 to 5.
Since it is about 60 degrees, it should be adjusted to the maximum angle of about 60 degrees,
It is preferable that the angle is changed by pressurizing the base plate 115.

To further ensure the elastic deformation of this girder heat insulating material 10,
As shown in FIG. 4, a plurality of notches 17 may be formed, and a space 18 may be formed between the eaves girder 113 and the projecting pieces 12a, 12b.

Further, in order to facilitate mounting of the girder heat insulating material 10 between the rafters 14 and to ensure pressure contact with the rafters, the girder heat insulating material 10
Slits may be formed at predetermined intervals in the direction between the rafters. The slit may be formed only on the rafter side end of the girder heat insulating material 10.

Next, in order to assemble a heat insulating structure of a building using such a girder heat insulating material 10, first, the eaves girder 113 is attached to the shaft assembly portion 112 such as the pillar 110 and the stud 111 which are erected on the base. A rafter 114 is hung on the eaves girder 113.

Next, the heat insulating material 10 for the girder is mounted between the rafters 114 so as to contact the eaves girder 113, and then the inclined surface 14 of the heat insulating material 10 for the girder is used as the base plate.
115a is pressed down from above, the roof heat insulating material 102b is provided, and the roof is put into operation. Then, the wall heat insulating material 102a is attached to the frame portion 112 such as a pillar or a stud.
It can be attached to the outside of. In this way, the roof heat insulating material 102b and the wall heat insulating material 102a are conveniently connected by the girder heat insulating material 10.

By doing this, it is not necessary to press the top of the large heat insulating material between the rafters 114 in a predetermined compressed state after cutting the top of the large heat insulating material in the field, and it is not a troublesome work. Efficiency is improved and construction costs are not increased.

Next, the embodiment shown in FIG. 5 will be described.

The girder heat insulating material 10 according to the embodiment shown in FIG. 5 has an airtight tape on the side surface 15 in contact with the eaves girder 113 and on the top of the wall heat insulating material 102a.
The bottom surface contacting via 20 is in the same plane, and has a flat plate shape as a whole. This girder insulation 10 is rafter 11
It is attached along rafters 114 between the rafters 114, and the angle of the purlin 113 is taken in to improve the airtightness of this part.
The height (thickness) of the heat insulating material 10 for the girder is preferably substantially the same as that of the rafter 114. Rafter 114 is generally 45,60,75,90mm
Since the girder heat insulating material 10 has the height (1), it is preferable to prepare the girder heat insulating material 10 having the height (thickness). In addition, the width l of the girder insulation 10 is 10
5 mm square is common, so 100-300 mm, especially 200 mm
It is preferably about the same. The wall heat insulating material 102a preferably has a maximum thickness of about 100 mm.

In addition, in each of the above-described embodiments, the external ventilation layer is formed on the outer side of the heat insulating material 102, but the present invention is not limited to such an embodiment at all, and the external ventilation layer is not provided. Also, the heat insulating material may have not only one layer but also a plurality of layers.
