Description

Panel and panel joint structure

The present invention relates to a panel used for, for example, a prefabricated refrigerator or freezer, a clean room or a ceiling, wall or partition of a building, and a joining structure thereof.

Generally, this type of panel is composed of a pair of surface plates, a frame member interposed between the side portions of the surface plates, and a foam insulation that is injected and filled into a space formed by the both surface plates and the frame member. From the viewpoint of bonding strength and airtightness, a fitting protrusion or fitting recess formed on the outer joint surface of the frame member is provided, and the fitting protrusion and fitting recess are provided. The strips are fitted together.

Further, in order to further improve the airtightness at the joint portion between the panels, a packing that contacts the joint surface of the other panel is provided on the joint surface of the frame material of the one panel to be joined.

As this type of conventional packing, a circular (cylindrical) hollow packing is used for both side surfaces (front and back) in the thickness direction of the mating ridge, and the thickness of the mating ridge or mating ridge. Those that protrude laterally from both side surfaces of the direction are known (see, for example, Patent Documents 1 and 2).

JP-A-8-261640 (Claims, paragraph 0015, FIGS. 1 and 2) JP 2008-82070 A (paragraph 0034, FIGS. 2 to 4)

However, since the packings described in Patent Documents 1 and 2 are both hollow with a circular cross section, the packing reaction force is strong and the packing cannot be crushed when the panels are joined together. For this reason, there is a concern that the contact area between the packing and the bonding surface of the panel is small, the gap between the panels is widened, and the airtightness of the bonding portion is lowered.

In addition, in the hollow packing having a circular cross section, in the bonding state between the panels, the gap between the panels is widened, and the deformation of the packing becomes irregular. There are also concerns such as unevenness and poor appearance.

The present invention has been made in view of the above circumstances, and it is possible to improve the airtightness of the joint portion between the panels, and to narrow the gap between the joint portions and improve the appearance of the joint portion, and the joining of the panels The purpose is to provide a structure.

In order to achieve the above object, a panel of the present invention is a panel comprising a pair of surface plates and a frame member interposed between the side portions of these surface plates, and the other panel in the frame member The joint surface is provided with a convex protrusion for fitting or a concave groove for fitting, and on both inner sides in the thickness direction of the panel, a packing that can contact the other panel is projected, A bent portion directed to the inner side of the panel is formed at the tips of both packings (Claim 1). In this case, it is preferable that the bent portion of the packing is formed in an arc shape.

By configuring as described above, in a state where the panels are joined together, the bent portion of the packing can be deformed to the inner side of the panel and can be brought into close contact with the joining surface of the other panel to be joined. In this case, by forming the bent portion in an arc shape, it is possible to prevent the bent portion from being elastically deformed excessively toward the inner side of the panel, and to suppress the joint joint between the panels from becoming deep. it can.

Further, the panel of the present invention includes a foam heat insulating material that is injected and filled in a space formed by the pair of surface plates and the frame material, and a connection member that connects ends in the longitudinal direction of the frame material. In this case, the frame member is formed in a substantially hat shape in cross section having the fitting protrusion or fitting groove, and the fitting protrusion. And a locking projection is formed at a portion of the fitting recess that is opposed to the space in the thickness direction, and the connecting member has a pair of engaging claws that can engage with the locking projection. Formed in a hat shape, the frame members are connected to each other by engaging the engaging claws of the connecting member with the locking projections from the space side in a state where the longitudinal ends of the frame members are in contact with each other. (Claim 3).

By configuring as described above, a panel having a dimension exceeding the standard length of the frame material can be produced by connecting the end portions in the longitudinal direction of the frame material with the connecting member. Further, it is possible to prevent the foamed heat insulating material injected and filled in the space formed by the pair of surface plates and the frame material from leaking outward from the connection portion of the frame material.

The panel joining structure of the present invention is a panel joining structure comprising a pair of surface plates and a frame member interposed between the side portions of the surface plates. The joint surface is provided with a fitting ridge or a fitting groove, and can be brought into contact with the other panel at both ends in the thickness direction of the frame material of one panel to be joined to each other. The bent portion is formed by projecting packing, and a bent portion directed inward of the panel is formed at the ends of both packings, and the bent portion for fitting and the recessed portion for fitting are fitted. The portion is in close contact with the other panel (claim 4). In this case, it is preferable that the bent portion of the packing is formed in an arc shape.

By configuring as described above, in a state where the panels are joined together, the bent portion of the packing can be deformed to the inner side of the panel, and can be brought into close contact with the joining surface of the other panels to be joined. The gap at the joint can be narrowed. In this case, by forming the bent portion in an arc shape, it is possible to prevent the bent portion from being elastically deformed excessively toward the inner side of the panel, and to suppress the joint joint between the panels from becoming deep. it can. Further, by making the bent portions of the packings provided on the panel have the same arc shape, the bent portions can be deformed substantially without irregularities.

Further, in the panel joint structure according to claim 4 or 5, it is preferable that the bent portion of the packing is in close contact with the bent piece of the surface plate of the other panel (claim 6).

By configuring as described above, the bent portion of the packing is brought into close contact with the bent piece of the surface plate located on the inner side of the outer joint surface of the frame member, so that the gap between the joint portions can be narrowed.

Panels with dimensions can be made. Further, it is possible to prevent the foam heat insulating material injected and filled in the space formed by the pair of surface plates and the frame material from leaking outward from the connection portion of the frame material, and to leak outward. It is possible to prevent adhesion of the foamed heat insulating material to the packing and obstructing deformation of the bent portion of the packing. Therefore, even in a panel having a size exceeding the standard size of the frame material, the airtightness of the joint portion between the panels can be improved, and the appearance can be improved by narrowing the gap between the joint portions.
