Description

[Detailed Description of the Invention] The present invention has a simple configuration and can exhibit excellent heat insulation effects.
The present invention also relates to a heat insulating board that is strong and can be installed easily and quickly in adiabatic manner.

Conventionally, various heat insulating plates have been developed in which a heat insulating material such as glass wool or foamed synthetic resin is entirely or partially covered with a metal plate.

However, there are disadvantages in that it is extremely troublesome to connect the heat insulating plates to each other or to attach them to structural members such as purlins and rims, and that the heat insulating effect cannot be sufficiently exerted at the attachment (connection) points.

Also, there were few strong female characters. Furthermore, the connection between the heat insulating plates was not completely protected from rain, and there was a drawback that it was not possible to securely attach the heat insulating plates to each other.

Therefore, the present invention covers the upper surface of the main heat insulating plate with cutout stripes formed at the lower corners of both sides and up to the middle of the cutout stripes on both sides with a metal plate, and covers the upper surface of the heat insulating main plate with cutout stripes at the lower corners of both sides with a metal plate. A protrusion is formed, and a large protrusion with a height higher than the protrusion is formed a little inside of the protrusion, and the protrusion has an enlarged section at the tip facing inward from the upper end of the large protrusion. By using a formed heat insulating board, the insulating board itself is strong, the structure is simple,
The heat insulation effect can be improved, and the protruding strips and protruding strips are formed in front of the connectable front, and the heat insulating plates can be easily and quickly connected to each other in a heat-insulating manner. It ensures that the installation location is protected from rain, provides strong installation, and eliminates the above-mentioned drawbacks.

Its structure will be explained with reference to the drawings.

Reference numeral 1 denotes a heat insulating main plate, which has a flat square cross section, a predetermined width, and is formed to be long.

This material may be glass wool, rock wool, wood wool, foamed synthetic resin (urethane, etc.), or the like.

Wood and concrete may also be used as insulation materials.

At the lower corner portions on both sides of the main plate 1, cutout strips 2, 2 are formed with inverted shapes in the longitudinal direction.

Reference numeral 3 denotes a metal plate, which covers the upper surface and both sides of the main heat insulating plate 1 up to the middle of the vertical portions of the cutout strips 2.

Projections 4, 4 are bent above both edges of the metal plate 3, and large projections 5, 5, which are taller than the projections 4, are bent slightly inside the projections 4, 4. This large ridge 5,5
A protruding strip 6.6 is formed inwardly from the upper end.

A fig-shaped enlarged section 7 is formed at the tips of the protruding strips 6, 6.

The metal plate 3 on which the protrusions 4, the large protrusions 5, the protrusions 6, and the enlarged section T are formed is formed by bending a single plate by a group of rolls.

To cover the main plate 1 with the metal plate 3, the bases of the protrusions 4, 4 on both sides of the metal plate 3 are widened in advance (see dotted lines in Figure 1), and after the main plate 1 is overlapped, the protrusions 4, 4, 4 Narrow the base and shape it as shown by the solid line in Figure 1.

The thus formed product is referred to as a heat insulating board A.

B is a joiner with a convex cross section, which is long and has a heat insulating part 8 on the upper surface and a bent metal strip 9 superimposed on the lower surface.
and forming stepped portions on both sides of the heat insulating portion 8,
Its width and height are equal to the width and height of the notch 2 of the main plate 1, and the strip 9 is formed slightly wider than the width of the heat insulating part 8.

C is a structural material such as a purlin and a rim.

The notched strip 2 is interposed between the heat insulating plates A and A on the stepped portion of the joiner B, and is placed on the structural member C.

D is a washer having a butt-shaped cross section, and its internal height is formed at the same height as the protrusion 4.

This washer is fitted onto the protrusions 4, 4 of the adjacent heat insulating plates A, A.

The washer is fixed to the structural member C by inserting the washer with a drill-like hole E and passing through the joiner B.

Although not shown, a plate with a tip-shaped bolt shaft protruding from the plate is fixed to the structural member C, and the bolt shaft is attached to the joiner B.
Sometimes the washer is fixed by inserting the washer and screwing it with a nut.

F is an elongated cap material, consisting of a vertical part 11 facing upward from both sides of the flat part 10, a horizontal part 12 facing outward, a bent part 13 facing downward, and a horizontal edge 14 facing outward,
It is integrally constructed.

This cap material F has its horizontal portions 12 and 12 placed on the adjacent protruding stripes 6, 6, and its bent portion 13 is bent to form the lower part of the protruding strip 6 [the enlarged section of the protruding strip 6]. A hollow portion 15 is formed between the lower surface of the portion other than point 7] and the bent portion 13.

Reference numeral 16 denotes a heat insulating material filled in the flat portion 10 of the cap material F between the adjacent large protrusions 5.5.

Since the present invention has the above-mentioned structure, in order to construct it, the heat insulating plates A and A are installed on the structural member C with a joiner B having a convex cross section interposed therebetween, and the adjacent protrusions 4 , 4, a washer with a butt-shaped cross section is fitted, and the washer is attached to the bolt E.
At this point, the joiner B is passed through and attached to the structural member C, the adjacent protruding strips 6.6 are covered with the cap material F, and the edges are bent to complete the construction.

In the present invention, protrusions 4, 4 are formed above both side edges of the metal plate 3 constituting the heat insulating plate, and the Q protrusions 4, 4Q are slightly inside.
By forming large protrusions 5, 5 that are taller than the protrusions 4, and further forming protrusions 6, 6 that extend inward from the upper ends, the metal plate 3 is bent at many points. Because of its high height, it has an extremely large section modulus and can provide a strong heat insulating board.

By forming the tip of the protruding strip 6 as an enlarged section 7, it is possible to prevent the plate to be integrally molded from collapsing and being damaged, and also to facilitate molding.

In addition, since the upper surface of the main heat insulating plate 1, which has cutout stripes 2, 2 formed at the lower corners of both sides, and up to the middle of the cutout stripes 2 on both sides, is covered with the metal plate 3, the metal plate 3 is attached to the main plate. Since the back side of the main plate 1 is not covered, and only the middle of the side of the main plate 1 is covered, even if the outside temperature that is transmitted to the metal plate 3 changes, it will be blocked by the heat insulating main plate 1, and the internal temperature will not be affected. It is possible to provide a heat insulating board with excellent heat insulating effect.

In particular, when the heat insulating board is placed on the metallic structural material C, the outside air does not reach the structural material C, making it possible to perform effective heat insulation treatment.

Furthermore, by covering the middle of the cutout strip 2 with the metal plate 3, the edges of the metal plate 3 sandwich both sides of the main plate 1 for insulation. In addition, even if the main plate 1 is brittle, it can be well protected by the metal plate 3, and damage to the main plate 1 can be prevented.

In addition, the protrusions 4 formed on both sides of the metal plate 3 can be fitted with washers when connecting adjacent heat insulating plates, ensuring a secure connection even if the heat insulating plates themselves are not provided with engaging parts. can be done.

Moreover, a large protrusion 5, 5 which is higher in height than the protrusion 4, 5 is formed on the slightly inner side of the protrusion 4, 4, and a protrusion ridge facing inward from the upper end of the large protrusion 5, 5 is formed. By forming 6,6,
By covering the adjacent protruding strips 6, 6 with the cap material F and bending the edges, it is possible to connect the adjacent heat insulating plates with each other, and also prevent rainwater from penetrating between the cap material F and the protruding strips 6. However, the presence of the protrusion 4 prevents it from penetrating into the interior.

This heat insulating board has a simple structure, can be mass-produced by roll forming, and can be provided at low cost.

According to the present invention, even if no engaging portions are formed between the heat insulating boards A and A, scaffolding etc. can be assembled by simply working from above the heat insulating boards A using the joiner B1 washer D1 bolt E1 cap material F. It can be quickly constructed as a roof or wall without requiring any skill.

Further, the cap material F is coated on the protruding strips 6, 6 of the adjacent heat insulating materials A, A, and the bent portion 13 of the cap material F is bent, and the lower part of the protruding strip 6 and the cap material F are bent. Since the hollow part 15 is formed between the part 13 and the cap material F
Even if rainwater infiltrates between the hollow part 15 and the protruding strip 6,
This prevents capillary action of rainwater and prevents it from penetrating into the cap material F and the large protrusion 5, making it possible to reliably shut off rain.Of course, by tightening the cap material F, the adjacent insulation The connection between plates A and A can be strengthened.

Also, since the joiner B is interposed between the heat insulating plates A and A, the joiner B is inserted into both the notches 2.2 of the main plate 191.
The step between the joiner B and the main plate 1 is bent in a zigzag shape, so that the joint between the main plates 1 and 1 is well blocked from air circulation between the inside and outside of the building. This makes it possible to form a hermetic seal, allowing connections to be made in an adiabatic manner, providing a heat-insulating roof and wall with good heat-insulating effects.

Also, since the washer is fitted onto the adjacent protrusions 4, 4 and attached to the structural member C using the pole E, the protrusions 4, 4 on both sides of the heat insulating plate A are attached to the structural member C by the washers. Repressed and fixed.

Therefore, the end of the insulation board A where the wind pressure is applied to the maximum is fixed,
A strong insulation board can be installed that will not come off due to strong winds, etc.

If a heat insulating material 16 is filled between the large protrusions 5, 5 and the cap material 1, the heat insulating effect at the connection point can be further enhanced.
