Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating panel used mainly for the ceiling, floor or wall of prefabricated refrigerators or warehouses.

In general, this type of insulation panel consists of a pair of face plates filled with an insulating core material such as foamed polyurethane, and in consideration of strength or load handling, at least one of the face plates has a plurality of panels parallel to each other. It is made of a wavy surface plate with ridges. Therefore, when used as a wall panel and connected to a floor part, for example, as shown in FIG. or, as shown in Fig. 2, a method of directly filling the space between the lower end of the wall panel a and the floor part d with the sealing material e. had been adopted. However, in the case of using the former, that is, the angle material c, the angle material c and the convex strip f
Since a gap is created between the groove g and the groove g between the panels, there is a disadvantage that cleaning water and dirt accumulate in the gap, making it unhygienic. In the method of joining the sealing material e to the floor part d, the sealing material e must be caulked along the wave shape, which poses problems such as the construction is troublesome and requires skill and a lot of time. Therefore, as a means to solve these problems, for example, a method can be considered to form the panel in a flat shape so that the protruding stripes do not appear at the edge of the panel.However, when a surface plate with such a shape is press-molded, the mold It became necessary to make major changes to equipment, etc.
It costs a lot of money and becomes a cost problem.

This invention was made in view of the above circumstances,
By connecting an end panel material having a flat part to a corrugated surface plate, which should solve the problem of panel end joints, it is possible to easily and reliably join panels at corner parts, and A heat insulating panel that can remove as much water or dirt from the joints as possible, simplify sealing work, and can be manufactured easily and inexpensively using normal equipment. This is what we are trying to provide.

Embodiments of this invention are shown below in Figures 3 to 13.
This will be explained in detail based on the figures.

3 and 4 show a first embodiment of the present invention, in which at least one surface plate 1 of a pair of facing surface plates 1 and 2 is formed by a plurality of parallel protrusions 3, 3, . . . ...and a wide convex strip 3a at both ends,
Formed with a wave-shaped surface plate having 3a,
An end face material 4 made of, for example, synthetic resin is fitted and connected to one end of the group of convex stripes of the wave-shaped surface plate 1, and a material such as foamed polyurethane is connected between this face plate 1 and the other face plate 2. It is filled with an insulating core material 5, and
A heat insulating panel is shown in which a holding angle member 7 is attached to the other end of a group of convex stripes of a corrugated surface plate 1 with a fixing device 6 such as a blind rivet, and a frame member 8 is provided around the periphery of the holding angle member 7. ing. In this case, as shown in FIG. 4, the end surface material 4 has overlapping portions 4a, 4a... having similar shapes to the protrusions 3, 3... that fit into the protrusions 3, 3... , a parallel part 4b that is parallel to this overlapping part 4a and located on almost the same plane as the top surface of the protrusions 3, 3..., and a parallel part 4b that is bent from the end of this parallel part 4b and extends along the panel peripheral edge. Peripheral part 4c
At least at both ends thereof, a wide cone-shaped overlapping part 4a' is formed, and a dovetail-shaped concave part 4e' is provided inside the overlapping part 4a'. Next, in processing the panel, first, the overlapping portions 4a', 4 of the end face material 4 are placed within one end of the group of convex stripes of the corrugated surface plate 1.
After inserting and fitting and connecting a'..., as shown in FIG.
A frame material 8 is interposed between the peripheral edge 4c and the angle material 7, and a bending line 2' bent from the end of the other surface plate 2, and a plurality of tightening bolts 9 are erected in parallel. , 9, and then a heat insulating core material 5 is foamed and filled between both surface plates 1, 2 to form a heat insulating panel. In this case, the end member 4
The overlapping portion 4a′ at both ends of the overlapping portion 4a′ of the corrugated surface plate 1
Since the convex strips 3a having a similar shape to a' are tightly fitted, the end member 4 and the wavy surface plate 1 can be held together only in the fitted state, and a block-shaped core material is formed inside during foaming. You don't have to put it in. Further, the peripheral edge 4c of the end member 4 and the angle member 7 are locked to the frame member 8, and can withstand the foaming pressure of the core member 5. Although the connecting portion 4d between the overlapping portion 4a and the parallel portion 4b of the end panel material 4 is shown to be at a right angle, it does not necessarily have to be at a right angle. For example, as shown in FIGS. 6 and 7, It may be an inclined connecting portion 4d'. If formed in this way, the adhesion of water, dirt, etc. can be further reduced. If the frame material 8 is not used, heat insulating core materials 5', 5' are arranged around the periphery as shown in FIG. If you connect them with , you can mold them in the same way.

FIG. 8 shows a second embodiment of this invention.
This is a case where the same effect can be obtained by simplifying the processing of the end face material 4. That is, there are only two overlapping portions 4a formed on the end surface material 4 that have a wide convergence shape and that fit with the protrusions 3, 3 located at both ends of the corrugated surface plate 1, and both overlapping portions 4a are This is a case where a receiving portion 4a that overlaps the lower surface of the surface plate 1 is formed in the portions 4a, 4a. In this case, both overlapping parts 4a of the end face material 4,
A sealing material 11 is interposed between the connecting portion 4d between the connecting portions 4a and the end faces of the convex strips of the corrugated surface plate 1, and as shown in FIG. If the overlapping portion of the portion 4e and the corrugated surface plate 1 are connected using a fixture 12 such as a blind rivet, leakage of the core material 5 can be prevented and the connection strength can be stabilized. In addition, by forming the end face material 4 with synthetic resin, a fixing protrusion f is erected near the center part on the receiving part 4e, and this protrusion 4f is
As shown in Figure a, the corrugated surface plate 1 is penetrated into the engaging hole 1a, and as shown in Figure b, the protrusion is heated and crushed with an electric iron or the like (not shown). Alternatively, as shown in FIG. 11, an engaging slit 4g is bored in the receiving portion 4e of the end panel 1, and the end of the corrugated surface plate 1 is inserted into the engaging slit 4g. The end face material 4 and the corrugated surface plate 1 may be connected by engaging the locking claws 1b bent from the end.

FIG. 12 and FIG. 13 show a third embodiment of the present invention, in which a corrugated surface material 1 is provided on an end surface material 4.
In the case where an overlapping portion 4a of a similar shape is formed with a dovetail-shaped protrusion 3a that fits in three places of the wide-cone-shaped protrusions 3a, 3a located at both ends of the dovetail-shaped protrusion 3a, and the protrusion located in the center. be. With this structure, the structure can be simplified compared to that of the first embodiment, and fixing means such as blind rivets or fixing protrusions as in the second embodiment are used. It is now possible to easily connect them without any hassle. In this case, it is easier to assemble if the frame material 8 is connected to the peripheral edge 4c in advance, and then the end panel material 4 and the corrugated surface plate 1 are connected.

In each of the above embodiments, one surface plate 1 is used.
Although we have shown the case where only the wafer is formed into a wavy shape, of course,
The other surface plate 2 may be similarly formed into a wave shape, and the end plate 4 may be connected to one end thereof, or the end members 4, 4 may be connected to both ends of one surface plate 1. You can also do it.

As explained above, in the heat insulating panel of the present invention, at least one of a pair of facing face plates is formed of a wavy face plate having a plurality of parallel ridges, and the ridges of the face plate At one end, there is an overlapping part having a similar shape to the wide convex strip that fits with the wide convex strip on both ends, a parallel part parallel to this overlapping part, and a fold from the end of this parallel part. An end face plate consisting of a curved peripheral edge along the panel periphery is connected to the overlapping part, and an insulating core material is filled between the wavy face plate including the end face plate and the other face plate. , the parallel part of the end face material is located without any convex stripes appearing on the joining side edge of the panel, and therefore the joining of the panels at the corner can be easily and reliably sealed, and the joint In addition, there is no risk of condensation water, dirt, etc. accumulating and becoming unhygienic, the structure is simple, it can be easily manufactured using existing equipment, and the panel can be adjusted to any length. Since it can also be used, it is possible to provide a wide variety of heat insulating panels at low cost, and its utility value is remarkable.
