DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a building insulation panel useful as a roofing material, an outer wall material, and other exterior materials.

[0002]

2. Description of the Related Art Conventional thermal insulation panels for buildings are disclosed in
Japanese Unexamined Patent Publication No. -20560 and Japanese Utility Model Publication No. Hei 3-4650 have proposed such a material, which is excellent in heat insulation and strength, but has the following disadvantages. In these panels, rainwater that has penetrated between the heat insulating layer and the metal front and back plates corrodes the front and back plates, opening a hole, causing a large water leakage accident, or before such corrosion, There is a problem that rainwater that has infiltrated into the room directly may cause a water leakage accident. Such a water leak accident is because the heat-insulating layer is made of a foamed resin and has extremely low self-water absorption and excellent heat-insulating properties, so that the intruded water stays in the fragile portion of the heat-insulating layer and the adhesive layer of the metal plate, It is even more critical because it promotes corrosion of the metal plate. Further, the length of the panel is a length that can be transported because molding on site is impossible because the heat insulating layer is formed by injection and foaming of a resin material for molding reasons, that is, 11.
The upper and lower panels are connected by providing a foamed resin or a seal at the connection portion. However, in the case of a connection structure in which a foamed resin or a seal is provided at such a connection portion, the connection portion is a hidden part that cannot be seen by an operator during or after work, so that the sealing state must be checked. However, there is a problem that the panel must be removed once when the operation is poor or the seal is deteriorated with time. In this way, since the panels themselves do not have self-draining capability, water leakage accidents due to corrosion are inevitable, and the infiltration of rainwater by the panels can be performed without installing foam resin or seals at the connection between the upper and lower panels. It is inevitable that a water leakage accident caused by dripping from a part of the room to the inside of the room, the work efficiency of connecting the upper and lower panels is poor, and the quality of the sealing state is unknown.

The problem to be solved is that a space portion vertically penetrating is formed between the inside of the concave portion of the back plate and the heat insulating material layer. An object of the present invention is to provide a method for manufacturing a heat insulating panel for a building, which has no gap between the heat insulating material layer and a panel having high soundproofing properties.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a required heat insulating material by injecting a foamable resin material between a metal front plate and a back sheet of an appropriate form and foaming. After the layer is formed, the heat insulating material layer is bonded to the back plate via the back sheet so that a space vertically penetrating between the concave portion of the back plate and the back sheet remains. It is characterized by integrating the three. Further, in the present invention, a back sheet is pasted in advance over each of the recesses in the metal back plate in the form of a plurality of recesses and projections formed in parallel in the up-down direction, and between the back sheet and the inside of the recess. Forming a space penetrating in the vertical direction, after that, foaming resin material is injected and foamed between the back sheet of this back plate and the metal front plate of an appropriate form to form a required heat insulating material layer. It is characterized by being formed and coalesced to integrate the three.

The front plate and the back plate in the present invention are formed by well-known appropriate forming means such as press working and roll working. The left and right ends of the surface plate include, as a configuration for the connection, in addition to a covering method by a simple polymerization, a well-known technique as a connecting means of a building exterior material such as a fitting method or a goby fastening method. Not restricted. The front and back plates are
For example, any plate material used for the exterior of a normal building, such as a material plated or colored on iron, aluminum, stainless steel, or the like, may be used. Examples of the foamable resin material forming the heat insulating material layer include hard urethane, isocyanurate, and phenol foam.

FIG. 1 illustrates an embodiment of the first aspect of the present invention in a method of manufacturing a heat insulating panel for building according to the present invention.
The front plate 1 and the back plate 2 are separately formed in advance.
The surface plate 1 has convex portions 4, concave portions 5, L-shaped side portions 9 at left and right end portions,
10, and the back plate 2 is formed into a structure having the convex portions 7 and the concave portions 6. Thereafter, a back sheet 11 is attached between the horizontal portions 9a and 10a of the left and right side portions 9 and 10 of the front plate 1, and the front plate 1 and the back sheet 1 are attached.
A heat-insulating material layer 3 is formed by injecting a foamable resin material into a space between the heat-insulating material layer 1 and foaming. Next, the heat insulating material layer 3 is fitted with the back plate 2 via the back sheet 11 so that a space 8 vertically penetrating between the recess 6 of the back plate 2 and the back sheet 11 remains. The three members are integrated by bonding (heat fusion, pressure bonding, etc.).

FIG. 2 illustrates an embodiment of the second aspect of the method for manufacturing a heat insulating panel for a building according to the present invention.
The front plate 1 and the rear plate 2 are separately formed and placed. The surface plate 1 has convex portions 4, concave portions 5 and L-shaped side portions 9, 10 at left and right ends.
The back plate 2 is formed into a member having a convex portion 7 and a concave portion 6 respectively. Thereafter, the back sheet 11 is attached to each of the protrusions 7 on the back plate 2 to form a space 8 vertically penetrating between the recess 6 and the back sheet 11. After doing so, the back sheet 1
The surface plate 1 is bonded (heat fusion, pressure bonding, or the like) through the substrate 1.
Next, a foamable resin material is injected into a space between the front plate 1 and the back sheet 11 and foamed to form a heat insulating material layer 3.
The three are integrated.

FIG. 3 shows an example of a roof that is roofed by using the heat insulation panel of FIG. 1 described above. Panels adjacent to the left and right are sandwiched by a suspension 13 standing upright on the base material 12 side. The right and left tip portions 13a, 13a of the suspension 13 are engaged with the concave recesses 4a, 4a on the upper surface of the adjacent left and right convex portions 4, 4,
Connected and fixed. The vertically adjacent panels are formed by placing the lower end portion 2b of the back plate 2 of the upper panel in a superposed state on the upper end portion 2a of the lower panel projecting above the back plate 2 of the lower panel. The space 8 of the panel is communicated up and down, and the lower end 1b of the upper panel, which protrudes below the upper surface 1 of the upper panel, is also superimposed on the upper end 1a of the upper panel. The upper and lower panels are connected by being covered, and the left and right convex portions 4 and 4 of the upper and lower panels are provided with engaging projections 14a that engage with the engaging recesses 4b on the side surfaces of the convex portions. A long cover 14 is fitted in the ridge direction, and the eaves are laid from the eaves side to the ridge side.

Thus, even if rainwater enters from the overlapping portions of the surface plate 1 in each of the upper, lower, left and right panels, the rainwater can be guided to the eaves side along the space 8 and drained without being retained in the panel. In addition, the end of the space 8 can be opened to the atmosphere or connected to an arbitrary air conditioner to improve the heat insulation efficiency or dehumidify. Then, even if the infiltrated rainwater tries to drip into the room from between the panels, the upper end 2a of the back plate 2 forming the space 8 protrudes to the back of the lower end 2b of the upper panel. The space 8 can be allowed to flow down to the eaves side after receiving rainwater. In addition, since the space between the left and right panels is covered with the cover 14, the infiltration of rainwater can be prevented.
