Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a metal heat insulation panel.

Conventional technology and its problems Various structures have been proposed as metal heat insulation panels, but all of them have problems during heat insulation construction.
The assembly and disassembly work is complicated, such as joining them together using appropriate joining fittings or fixing the panels one by one to the surface to be insulated using stud bolts, etc., and the workability is not good. In terms of performance, it still wasn't good enough.

The present invention was made with the aim of eliminating these conventional problems.

Means for Solving the Problems In the present invention, the panel body is made of metal and is hollow, and has a dovetail portion at the joint end, and a plurality of corrugated metal plates are installed in the hollow part of the body. , relates to a metal heat-retaining panel characterized in that it is filled in a stacked state in the thickness direction with or without using flat metal plates.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the panel body, and its shape may be any regular polygon, rhombus, trapezoid, etc. as long as it can be joined sequentially at the joint end surface, and a regular hexagonal shape is shown in the figure. ing.

The panel body 1 is made of metal and is hollow, and metal materials include duralumin, aluminum, iron,
Various metals can be used, such as zinc and stainless steel.

When these panels are actually applied, for example, aluminum with a low emissivity is used for heat insulation in high temperature areas, and stainless steel is used for heat insulation in relatively low temperature areas.

Inside the panel main body 1, there are a plurality of corrugated metal plates 12 (second to six
(see figure), with or without the flat metal plate 13 (see figures 2 to 5) (see figure 6),
The metal plates 12 are filled in a stacked state in the thickness direction, and a honeycomb portion 11 (see FIG. 1) is formed in the panel body 1 by filling the metal plates 12 in this way.

A dovetail portion is formed in the middle of the joining end portion of the panel body 1. As is well known, dovetail holes 21
and a dovetail pattern 22 fitted into the dovetail hole 21, and in the case of the hexagonal shape shown in the figure, the dovetail hole 21 and the dovetail pattern 22 are alternately formed at the joint end, for example. . In this system, only one type of panel body 1 may be used, but, for example, a panel body having only dovetail holes and a panel body having only dovetail patterns may be used as a set.

In the metal heat insulating panel of the present invention, as shown in FIG. It can be joined and integrated by splicing. In this case, the panel is made of metal, and the dovetail holes 21 and dovetail handles 22 are both made of metal materials, so they have excellent strength, and there is no risk of damage when fitting the dovetail holes 21 and dovetail handles 22 together. You can work safely, reliably, and efficiently.

Furthermore, assemble the panel body 1... in the same plane,
In the obtained heat insulating layer, since the panel bodies 1 and 1 are joined and integrated with each other by dovetail joints, it is essentially a single piece, and for example, the ends of the heat insulating layer can be fixed to the heat insulating construction surface. The whole panel can be fixed by using the 3-layer panel, which makes construction much easier than fixing the panels one by one to the construction surface.

Further, since the dovetail joint can be easily removed by shifting the panel bodies 1, 1 in a direction perpendicular to the joining direction, it can be easily disassembled without damaging the panel when necessary.

Effects As described above, the metal heat insulation panel according to the present invention has a structure that can be joined and integrated by dovetail joints, making it easy to perform heat insulation construction and improve workability. Furthermore, since the inside of the panel body has a honeycomb structure with metal plates filled inside, it is possible to prevent air convection and radiant heat transfer, and improve heat retention performance.
