Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to metal heat insulating panels mainly used for constructing exterior walls.

Conventionally, this type of insulation panel is known to have a structure consisting of a steel frame, inner and outer face plates attached to the steel frame, and a heat insulating layer filled in the internal space surrounded by the face plate and the steel frame. There is. In this conventionally structured heat insulating panel, since a steel frame is used as the frame, the heat transfer area and weight per unit area are large, resulting in a lack of heat insulation and light weight.

In general, the width of this type of insulation panel can be standardized to some extent, but the length needs to be adjusted to the actual situation at the construction site. It is therefore advantageous to be able to assemble panels of this type from long pieces of material which can be cut to any desired length. However, in the above-mentioned type that uses a steel frame, the steel frame must be custom-ordered for each different panel length, leading to a rise in production costs.

The present invention has been devised to eliminate all of the above-mentioned conventional problems, and will be described below with reference to drawings showing embodiments of the present invention.

In the figure, 1 is a corrugated metal inner panel face plate which is elongated in the vertical direction, and the inner panel face plate 1 is usually made of painted iron plate, synthetic resin coated iron plate, or aluminum plate. used.

The horizontal strap 2 is attached to the lower surface of the inner panel face plate 1 (first to
(see Fig. 3) or the upper surface (see Figs. 4 and 5) at intervals in the vertical direction. The number of horizontal straps 2 to be used is arbitrary, and they are usually provided at one or several locations at both the front and rear ends and in the middle.

A heat insulating layer 5 is formed over the entire surface of the inner panel face plate 1. In the figure, the heat insulating layer 5 is connected to two of the heat insulating plates 5a.
Although a case is shown in which plates are laminated, the number of laminated plates is arbitrary and may be one or more. As the heat insulating board 5a, a foamed synthetic resin board such as foamed polyethylene or foamed polystyrene, or an inorganic fiber board such as glass wool or rock wool can be used.

Vertical straps 6 are provided on the heat insulating layer 5 at intervals in the width direction, for example, at appropriate positions on both sides and in the middle. It extends over substantially the entire length of layer 5.

An outer panel face plate 9 is provided on the heat insulating layer 5. This outer panel face plate 9 has the same shape and structure as the inner panel face plate 1, and each of the vertical straps 6 is accommodated in its crest 9a.

The tightening bolt 3 connects the horizontal strap 2 and the vertical strap 6,
It is provided for tightening and integrating via the heat insulating layer 5.

By screwing a nut 4 into the lower part of the bolt 3, the bolt 3 can also be used as a fastening fitting for the horizontal strap 2 and the inner panel face plate 1, as shown in FIGS. 1-2 and 4. The horizontal band 2 and the inner panel face plate 1 may be fastened together using a fastening fitting other than the bolt 3, such as a bolt 3', as shown in FIG. 6, for example. These bolts are fixed to the horizontal strap 2 by means such as nuts or welding.

Furthermore, another tightening bolt 8 is provided for tightening the vertical strap 6 and the outer panel face plate 9 together. The bolts 8 are fixed on the vertical strap 6 at intervals in the vertical direction by applying suitable means such as nuts or welding.

A metal side cover 13 is installed so as to close between the joint edges of the inner and outer metal panel face plates 1 and 9.
A pair of left and right sides are attached and fixed between the face plates 1 and 9. This side cover 13 has a groove 13a along the longitudinal direction for inserting a rod-shaped packing 14.

In the heat insulating panel of the present invention, the inner and outer panel face plates 1 and 9 on both sides of the heat insulating layer 5 have bolts 3...
Since they are simply connected in a dotted manner, the heat transfer area is extremely small, and they have excellent heat insulation properties even though the inner and outer panel face plates 1 and 9 are made of metal. This heat insulation property is achieved by arranging the vertical strap 6 within the peak 9a of the outer panel face plate 9 so as not to contact the face plate 9, as in the illustrated embodiment, and by connecting the vertical strap 6 and the face plate 9 to Further improvement can be achieved by configuring the bolt 3 to be tightened by the bolt 3 located approximately in the middle of the bolts 3, 3. This is because with such a configuration, heat is transmitted to the outer panel face plate 9 via the bolts 3, straps 6, and bolts 8, and the heat transfer distance is far greater than when heat is transmitted directly from the vertical straps 6 to the face plate 9. This is because as the length increases, heat transfer occurs via the bolt 8, so the heat transfer area can also be reduced. Furthermore, this heat insulation property is achieved by attaching the mounting bracket 2 as shown in the figure.
By attaching it to the wall body a (see Fig. 7) via the panel a, the inner and outer panel face plates 1 and 9 can be
Further improvement can be achieved by inserting a heat insulating material (not shown) into the crest of the ridge.

In addition, in conventional insulation panels of this type, the internal insulation material tends to shift during transportation or construction, forming voids inside and reducing insulation performance, but in the present invention, the insulation layer 5 is skewered through the bolts 3... In this state, the inner and outer panel face plates are tightened, so an extremely stable and reliable laminated state can be ensured, and the problem of deterioration of insulation properties, which is a concern during transportation and construction, can be avoided.

Further, the length of the heat insulating panel of the present invention can be easily changed by appropriately changing the cutting lengths of the inner and outer panel face plates 1 and 9 and the vertical straps 6. According to the present invention, it is possible to mass-produce panel components and keep them in stock, thereby reducing production costs.

Furthermore, in the present invention, since the vertical straps 6 and the horizontal straps 2 are used as aggregates, the panel face plates 1 and 9
Coupled with the reinforcing effect of the crests 1a and 9a, extremely excellent strength is obtained as a whole, and these straps 2 and 6 have a smaller weight burden than when using a steel frame, reducing weight. be able to.

Furthermore, in the present invention, by changing the length of the bolt 3 and changing the thickness of the heat insulating layer 5 accordingly,
The overall thickness of the panel can be easily adjusted.

Furthermore, in the present invention, since the side cover 13 with grooves 13a is provided at the joining end of the heat insulating panel A, when joining the panels A, the seventh
As shown in the figure, the watertightness of the joint can be ensured by inserting the rod-shaped packing 14 across the grooves 13a, 13a of the joint, and thus the watertight joining of the panels A can be carried out easily. The watertightness of this joint can be further improved by interposing a sealing material 15 between the joints.

In this way, the heat insulating panel according to the present invention not only has excellent strength and heat insulation properties, but also allows for easy joining work while maintaining watertightness, greatly enhancing the usefulness of this type of metal heat insulating panel. It has features that can be improved.
