DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating board formed by solidifying glass wool or the like into a plate shape, and more particularly to a heat insulating board for heat insulation of a floor.

[0002]

2. Description of the Related Art In a cold region or the like, as shown in FIG.
2 is placed to insulate the floor.

FIG. 7 is a graph showing the relationship between the density of a heat insulating board using glass wool and the thermal conductivity. From this graph, it can be seen that as the density increases, the thermal conductivity decreases and the heat insulating effect increases up to a density of about 20 kg / m3. However, if the density exceeds 30 kg / m3, improvement in heat insulation efficiency cannot be expected even if the density is further increased. Therefore, the density of the heat insulating board is conventionally set to 30 to 40 kg / m3.

[0004]

As described above, in the prior art, the thickness of the heat insulating board is substantially equal to the height of the joist because the heat insulating board is mounted on a large portion between the joists. . In other words, if the thickness of the insulation board is made larger than the height of the joist, the top of the insulation board will protrude and the floorboard (finishing material)
The thickness of the heat insulating board is limited because it hinders the mounting of the heat insulating board. Further, as described above, since the density of the currently used heat insulating board is 30 to 40 kg / m3, the heat insulating effect cannot be enhanced without increasing the thickness.

Therefore, in cold regions, etc., a receiving material such as a plate, a net or a sheet is provided under the pulling bar, and another insulating material having a relatively low density is put on the receiving material to construct two layers. However, this method is troublesome and laborious.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a heat insulating board mounted on a large part of a floor of a building, wherein the heat insulating board has an upper half part protruding above the large part. It consists of the lower half located in the main room, and furthermore, an angle-shaped notch is formed at the end of the heat insulating board, into which the corner of the large room fits,
The surface of the angled notch is impregnated with a resin material, and
The end face of the upper half is not impregnated with a resin material.
Insulation board comprising angled notch and end face of the upper half
Was configured such that the side end face was exposed.

[0007]

The joist is crossed over the pulley, and then the heat insulating board is placed on the pulley between the joists such that the notch is fitted into the corner of the pulley.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a perspective view showing a state in which the heat insulating board according to the present invention is mounted on the large pulley, and FIG. 2 is a view as seen in the direction of arrow A in FIG. 2, and a heat insulating board 3 is placed between the joists 2 on the pulling table 1.

The heat insulating board 3 is formed by laminating glass wool 4 coated with an adhesive in the thickness direction, heating and forming the same into a plate shape, and having a moistureproof layer 5 on the upper surface. When it is necessary to further improve the workability and waterproofness during construction, a moisture-permeable and waterproof protective layer 6 may be provided on the lower surface.

Here, as the moisture-proof layer 5, aluminum foil, aluminum-deposited polyethylene film, aluminum foil kraft paper, asphalt-coated kraft paper, polyethylene film or the like is used, and as the protective layer 6, non-woven fabric or paper is used.

The heat insulating board 3 comprises an upper half 3a and a lower half 3b. The upper half 3a has the same height as the conventional one, that is, approximately equal to the height of the joist 2, and the thickness of the lower half 3b is required. It is set arbitrarily according to the heat insulation effect to be used. Further, the length of the heat insulating board 3 is made slightly longer than the dimension between the large and the small 1.
For example, if the dimension between the large drawers 1 and 1 is 910 mm, the length of the heat insulating board 3 is 912 mm and the heat insulating boards 3 are densely placed on the large drawer 1.

An angled notch 7 is formed at the end of the upper half 3a and the lower half 3b. This notch 7
Halves the upper surface of the pulley 1 so that the ends of the adjacent heat insulating boards 3 come into close contact with each other.

The above-mentioned notch 7 is formed at a site or the like by a cutter 10 shown in FIG. That is, the guide plate 1 of the cutter 10
1 is applied to the side surface of the heat insulating board 3, the guide plate 12 is applied to the upper surface of the heat insulating board 3, and in this state, the cutter 10 is pulled in the direction perpendicular to the paper surface, and the corners are removed by the blades 13 and 14 whose tips are perpendicular to each other to cut out the notch. Form. Here, since the heat insulating board 3 is formed by laminating and solidifying the fibers in the thickness direction, the cutting by the blade 13 has little resistance but is difficult to cut accurately. Therefore,
In the process of continuously manufacturing the heat insulating board 3 in a strip shape,
Cutting devices may be provided on both sides of the heat insulation board transport line, and grooves for receiving the blades 13 may be formed in advance on the side surfaces of the heat insulation board, and the blades 13 may function as guides when forming the cutouts 7.

[0014] FIG. 4 is a front view of the insulation board, the present invention
In the heat insulating board according to (1), the surface of the angled notch 7 is impregnated with a resin to form a hard layer 8 so that the strength of the end portion is increased and the fitting into the large pulley 1 can be performed smoothly. Also, as shown in FIG.
Of the side end surface other than the angled notch 7,
The end face of the half part 3a is not impregnated with the resin, so that the material is wasted.
Is omitted. Further, the moisture-proof layer 5 is moved from the side end of the heat insulating board.
Let it protrude and turn that part back to the side edge of the insulation board
Without coating, the end face of the upper half

FIG. 5 is a perspective view of a heat insulating board according to another embodiment. In this embodiment, the length of the heat insulating board 3 is made twice as long as that of the heat insulating board, and the large pulley 1 fits into the lower surface of the center. A channel-shaped notch 9 is formed. With such a shape, it is possible to reduce the time required for the work of fitting into the pulling bar.
