Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a heat insulating interior/exterior material used for roofing materials, exterior wall materials, interior wall materials, etc. of livestock housing buildings such as chicken houses, pig pens, and cow pens.

(Prior art) Since the above-mentioned farm building is required to maintain the indoor temperature at a temperature suitable for farm production regardless of the season, it is recommended to use materials with heat insulation properties as the roof and exterior wall materials. desired.

Therefore, as a heat-insulating interior and exterior material that can be used for the above-mentioned roofing materials, exterior wall materials, and even interior wall materials, a heat-insulating layer made of synthetic resin foam such as styrene or urethane has been applied to one side of a substrate made of corrugated or flat plates. It has been proposed that the two be combined together. This heat insulating interior/exterior material is generally a rectangular board laminated to a heat insulating layer, and one end in the width direction or longitudinal direction protrudes from the heat insulating layer, forming a stacked connection piece. When connecting the two insulation materials, overlap the connecting piece of the board of one insulation material and the other material to prevent rainwater from entering from the connection part. The heat insulating layers of the interior and exterior materials are brought into contact with each other at the above-mentioned connecting portions so as to be continuous.

However, in the case of conventional insulation interior and exterior materials,
Since the end face of the heat insulating layer was perpendicular to the direction in which the two heat insulating interior and exterior materials were arranged, the following problems occurred.

For example, when connecting two heat-insulating interior/exterior materials whose substrates are corrugated synthetic resin sheets, the peaks and troughs of the overlapping connection piece of the substrate of one heat-insulating interior/exterior material are connected to the peaks and troughs of the substrate of the other heat-insulating interior/exterior material. In this case, the two heat-insulating interior and exterior materials are positioned relative to each other in the width direction by the above-mentioned engagement between the peaks and the valleys. Therefore, it has been difficult to connect the two insulation layers of the insulation interior and exterior materials to each other without any gaps and to make them continuous. In other words, in order to butt both heat insulating layers without any gaps, the end faces of one heat insulating layer and the end faces of the other heat insulating layer must correspond accurately to the peaks or troughs of the corrugated board that is bonded to each other. This is because the end face of the heat insulating layer must be positioned with high accuracy in order to do so. Therefore, in reality, it is common that a gap is created between the abutted portions of the heat insulating layers of the two connected heat insulating interior and exterior materials. If there is a gap between the heat insulating layers as described above, the heat insulating properties will be lowered accordingly, and furthermore, there is a problem that the substrate can be seen through the gap. Further, there was also the problem that the heat insulating layers interfered with each other, making it impossible to overlap the crests and troughs of the overlapping connection pieces of one substrate in correspondence with the crests and troughs of the other substrate.

(Problem to be solved by the invention) The problem to be solved by the invention is that even if the position of the end face of the insulation layer is not set with high precision, when two insulation interior and exterior materials are connected. The key is to ensure that both insulation layers are butted against each other without any gaps so that they are continuous.

(Means for solving the problem) A heat insulating layer is integrally provided on a substrate having a shape in which peaks and valleys are alternately repeated in the width direction, and the board includes at least one peak and one valley. One end in the width direction protrudes from one end surface of the heat insulating layer in the width direction to form a lap joint piece, and the one end surface of the heat insulating layer extends from the root portion of the lap joint piece in the protruding direction of the lap joint piece. The other end face of the heat insulating layer in the width direction is inclined at the same angle in the same direction as the one end face of the heat insulating layer from the other end in the width direction of the substrate. The one end surface and the other end surface are positioned at corresponding locations of peaks or valleys on the substrate.

(Function) According to the above-mentioned means, when the overlap connection piece of one board of the two heat-insulating interior/exterior materials is superimposed on the other end of the other board, the insulating layers are inclined. The two end faces overlap and both insulation layers are continuous. In that case, even if the end faces of the heat insulating layers are not positioned accurately, the end faces of both heat insulating layers are shifted in the direction of inclination and overlap.

(Example 1) As illustrated in FIG. 1, the heat insulating interior/exterior material A consists of a substrate 10 and a heat insulating layer 20 provided integrally with this substrate 10. For the substrate 10, a corrugated plate made of vinyl chloride, acrylic, polycarbonate, or a synthetic resin reinforced by mixing these with glass fiber is used. One end of the substrate 10 in the width direction of the heat insulating interior/exterior material A protrudes from one end surface 21 of the heat insulating layer 20 to form a stacked connection piece 11, as shown in detail in FIG. The width of the overlapping connection piece 11 should be such that it includes at least one peak and one valley, and usually the width is about one and a half pitches at the peak or valley. Furthermore, one end of the substrate 10 in the longitudinal direction of the heat insulating interior/exterior material A is also covered with a heat insulating layer 20, as shown in detail in FIG.
The overlapping connection piece 12 protrudes from one end surface 22 of the connecting piece 12 . Next, the heat insulating layer 20 is made of a hard synthetic resin foam such as urethane or styrene, and one end surface 21 in the width direction of the heat insulating interior/exterior material A is connected from the base of the overlap connection piece 11 to the overlap connection piece 11. The other end surface 21a is inclined at a predetermined angle in the opposite direction to the protruding direction, and the other end surface 21a is inclined from the other end in the width direction of the substrate 10 in the same direction as the one end surface 21 at the same angle. Further, one end surface 22 and the other end surface 22a in the longitudinal direction are each inclined in the same direction at the same angle. Further, one end surface 21 and the other end surface 21a of the heat insulating layer 20 are positioned at corresponding locations of the peaks on the substrate 10.

When such heat insulating interior and exterior materials A are connected in the width direction as shown in Fig. 4, as shown in detail in Fig. 5, the two adjacent heat insulating interior and exterior materials A, In between, one of the insulation interior and exterior materials A
The overlap connection piece 11 of the board 10 is connected to the other end 11a of the board 10 of the other heat insulating interior/exterior material A, with its peaks and valleys
Overlap them from above so that they correspond to the peaks and valleys of each. In this way, both the heat insulating layers 20, 20 are continuous with their inclined one end surface 21 and the other end surface 21a abutted against each other without any gap.

In this case, it is possible that one end surface 21 and the other end surface 21a of the heat insulating layers 20, 20 are not accurately positioned at corresponding locations of the peaks on the substrate 10.
For example, one or both of them may protrude outward beyond a predetermined location. Even in such a case, as shown in FIG.
When the two heat insulating interior/exterior materials A, A are positioned in the width direction by the overlap of the overlap connection piece 11 and the other end 11a, both the heat insulating layers 20, 20 are connected to one end surface 21 and the other end surface. Since the heat insulating layers 21a are overlapped with each other with their positions shifted in the direction of inclination, these heat insulating layers 20, 20 are continuous without any gaps.

Furthermore, when the heat insulating interior/exterior materials A are arranged and connected in the longitudinal direction, the overlapping connection piece 12 of the substrate 10 in the same direction is overlapped with the other end of the board 10 of the adjacent heat insulating interior/exterior material. In this way, both the heat insulating layers 20, 20 overlap at one end surface 22 and the other end surface 22a and are continuous without any gaps. In addition,
One end surface 22 and the other end surface 22 in the longitudinal direction of the heat insulating layer 20
A does not necessarily need to be inclined, and may be cut vertically. Even in this case, by aligning the peaks and troughs of the two heat-insulating interior and exterior materials A, A in the longitudinal direction, it is possible to easily bring the vertical one end surface 22 and the other end surface 22a of the heat-insulating layer 20 into close contact.

In this embodiment, as is clear from FIG. 2, the inclined one end surface 21 and the other end surface 21a of the heat insulating layer 20 are positioned at the peaks of the substrate 10, but these are located at the valleys of the substrate 10. You may also set the position. When the position is set at a mountain part, both are placed on the part that becomes the ascending slope of the rainwater infiltration path between the substrate 10 and the stacked connection piece 11 that is formed when the two heat-insulating interior and exterior materials A, A are connected. Since the abutting part of the heat insulating layers 20, 20 is facing, it is difficult for rainwater to enter this abutting part, and the effective width of the insulating interior/exterior material A, that is, the width excluding the stacked connection piece 11 of the board 10, is half the pitch of the mountain part. It has the advantage of being longer.

Further, as shown in FIG. 4, the heat insulating interior/exterior material A at the beginning of reeding does not have the overlap connection piece 11 on the other end surface 21a, and the heat insulating layer 20 is cut vertically, while the heat insulating material A at the end of reeding The heat insulating layer 20 on one end surface 21 of the interior/exterior material A is cut vertically, so that the side surfaces of the roof or the like to which the heat insulating interior/exterior material A is connected are made beautiful.

The substrate 10 of the heat insulating interior/exterior material A is not limited to the case where it is a smoothly continuous corrugated plate as described above.
Even if it is a so-called square corrugated plate, as shown in FIG. 7, peaks of different shapes may be formed at predetermined pitches. Each of these has a shape in which peaks and valleys are alternately repeated in the width direction of the heat insulating interior/exterior material A.

Further, as a means for integrating the heat insulating layer 20 with the substrate 10, it is preferable to employ a method using an adhesive, a double-sided adhesive tape, or other known methods. In that case, as shown in FIG.
0 and the peaks of the substrate 10 and the heat insulating layer 2.
An air layer 30 may be maintained between the two. This has the advantage that the required amount of the synthetic resin foam constituting the heat insulating layer 20 can be reduced by the volume of the air layer 30 without reducing the heat insulating effect.

(Effects of the invention) According to the invention, since the end faces of the heat insulating layers are inclined, when the two heat insulating interior and exterior materials are connected, both the heat insulating layers are continuous without any gaps. Therefore, it is possible to avoid deterioration in heat insulation properties due to the presence of gaps in the connecting portions. This is particularly useful when the substrate is a corrugated sheet and the end faces of the insulation layer are not precisely positioned relative to the substrate. Furthermore, even if a gap is created between both heat insulating layers, the heat insulating effect will be reduced accordingly, but there is an advantage that the substrate will not be visible through the gap. In addition, since one end surface and the other end surface of the heat insulating layer are inclined at a predetermined angle in the opposite direction to the protruding direction of the overlap connection piece of the board, when the heat insulating interior and exterior materials are installed side by side in the width direction, one Even if the overlapping connection pieces of the boards are stacked from above so that their peaks and valleys correspond to the peaks and valleys of the other end of the other board, the heat insulating layer does not become distorted. Just by stacking them from above in this way, the end faces of the heat insulating layers overlap each other and are continuous without any gaps, which is a great effect.
