Description

[Detailed description of the invention] The invention relates to a heat insulating panel with a sandwich-inch structure in which a heat insulating material is filled between a pair of face plates, and in particular, at least one face plate is made of a corrugated plate with uneven stripes formed thereon. Regarding insulation panels.

Conventionally, in order to improve the panel rigidity and the mounting means of the sandwich-inch structure insulation panels, various types of insulation panels have been provided in which the surface plate has irregularities such as corrugated or rectangular cross sections in the shape 715.

However, in any of these heat insulating panels, the uneven stripes on the corrugated board are formed over the entire length or width of the panel from one panel edge to the other panel edge.

That is, the cross-sectional shape of the uneven stripes is directly exposed in the thickness direction of the panel at both panel edges that intersect with the uneven stripes.

Conventional heat insulating panels like this were mainly intended for use in constructing walls, so for example, for aesthetic reasons where the concave and convex strips are connected directly by connecting panels, etc. It is desirable that the uneven stripes extend over the entire length or width of the panel.

However, on the other hand, this panel structure has the disadvantage that the panel orientation is limited by the direction of the uneven stripes, the connection structure between the panels becomes complicated, and the airtightness is reduced.

Furthermore, when this panel structure is used to form a floor, the ends of the uneven strips at the panel joint edges are weak in strength, and the disadvantage is that they gradually become depressed when a load is applied to the ends of the raised strips. It also has (・ru.

Therefore, it is inappropriate to use it in places where loads are applied randomly.

The aim of the invention is to eliminate the aforementioned disadvantages and to provide an inexpensive panel that can also be used for floors.

For this reason, the inventive feature is that the uneven stripes do not extend to the edge of the panel, leaving a flat portion without the uneven stripes along the entire circumference of the edge of the panel.

An unconceived embodiment will be described below with reference to the drawings.

The unconventional panel shown in FIGS. 1 and 2 is a heat insulating panel with a sandwich structure in which a heat insulating core material 3 formed by foaming polyurethane, for example, is filled between a pair of face plates 1 and 20. The plurality of parallel protrusions 4 formed only on the surface plate 1 do not extend to the edge of the panel, but terminate at a position at an appropriate distance from the edge of the panel, forming an edge 4A. ing.

That is, a flat portion is left along the edge of the panel that intersects with the extending direction of the protrusion 4.

This flat portion is flush with the edge flat portion along the panel edge in the same direction as the extending direction of the protrusion 4, thereby forming a flat edge having the same panel thickness over the entire circumference of the panel. It looks like this.

As shown in FIG. 2, a convex portion 3A and a concave portion 3B are formed on opposite edges of the panel, respectively, so that the panels can be easily and reliably connected to each other.

However, of course, the edge member 5 is attached as shown in FIG.
The connection can also be configured using a suitable mating member.

The surface plate 1 having protrusions +4, that is, the corrugated plate, can be formed directly by pressing a flat plate member, or by flattening it along the edge of a normal corrugated plate that already has protrusions over its entire length or width. It can be easily made by known methods such as press working to form parts.

Such uncontrived insulation panels have flat edges with the same thickness along the entire circumference, so the direction and dimensions of the protrusions 4, 4, etc. are required to connect the panels. , it becomes possible to orient the panel regardless of the pinch.

In addition, since the strength of the end portion 4A of the protruding strip 4 is increased, the problem of the end portion being dented as in the conventional case is eliminated even when used as a floor spreader.

Therefore, it becomes possible to directly construct a heat insulating floor body of a frozen/refrigerated warehouse or the like using heat insulating panels.

Especially when using insulation panels on the floor of frozen and refrigerated warehouses,
Conventionally, insulation panels with a corrugated surface plate have the above-mentioned drawbacks. Therefore, in general, side-plane insulation panels are used, and insulation panels are installed on concrete floors with square wood, etc. They placed them and placed bamboo screens on top of them.

However, the unconventional heat insulating panel eliminates the above-mentioned drawbacks, and by using a heat insulating panel that has convex stripes on both sides, there is no need for a mounting stand or screen made of square wood.

The cross-sectional shape and orientation of the protrusions formed on the surface plate can be appropriately selected depending on the intended use so that the flow of cold air and water can be maintained in a preferable manner, and the ridges have the required strength.

For example, in addition to forming protrusions on only one side as shown in FIG. 3, protrusions 11 may be formed on both surface plates 10 as shown in FIG. 4, or on both surface plates 20 as shown in FIG. The protrusions 21 may have different orientation force directions, the protrusions 31 may be formed obliquely on the surface plate 30 as shown in FIG. and 42, etc.

As mentioned above, the unconventional feature is that a flat part of the same thickness is formed along the edge of the panel, which solves the above-mentioned drawback, and it is possible to change the shape and orientation of the protrusions or the shape of the edge of the panel. Panels can be connected together without being limited by the structure for joining, and the strength of the panels themselves can be increased.

What's more, the ridges themselves are highly practical as they double as floor mounts and screens, and also serve as a passageway for cool air when carrying loads.
