Description

[Detailed description of the invention] This invention relates to exterior panels used to construct low-temperature warehouses etc. for purposes such as freezing and refrigeration.
In particular, it relates to an exterior panel that has both heat insulation and moisture proof functions, and has excellent workability and durability.

It is important for low-temperature warehouses to have the required thermal insulation performance and to be completely prevented from infiltrating water vapor in the outside air (moisture-proof). However, meeting these requirements is not easy in practice. Firstly, insulation material is placed around a building frame such as a steel frame or reinforced concrete structure, but this insulation material is usually inserted and fixed through bolts that protrude from the building frame. However, according to this method, the bolts cause local heat bridges, causing problems such as dew condensation on the outside wall. Possible countermeasures to this problem include, for example, using wood or resin with low thermal conductivity for the aggregate of the frame to which the bolts are attached, or increasing the thickness of the insulation layer only around the bolts, but all of these methods increase costs. It is inevitable that the insulation work will become more complicated.

For the following, when performing the above-mentioned insulation construction, a method is adopted in which asphalt or polyethylene film is interposed as a moisture barrier layer, but in the case of asphalt, it is necessary to apply at least 5 to 6 times, making the construction time-consuming. However, there is a risk of cracking due to heat shrinkage of the frame, and there are also problems with durability. Furthermore, even when polyethylene film is used, holes must be made in the film to pass through bolts, etc. that fix the insulation material to the building frame, making it difficult to reliably perform moisture-proofing in that area.
Also, as with asphalt, the workability cannot be said to be good.

The present invention aims to solve all these problems at once and provide an exterior panel that can easily achieve moisture-proofing and heat insulation that meets the above requirements.
A panel with insulation material filled between the panels.
Its main features are: 1. Open web material is used for the frame of the frame;
The formation of heat bridges is avoided as much as possible. 2. Weldable anti-glare stainless steel plates are used as exterior panels, and the edges of the stainless steel plates are arranged to form a mountain shape with the edges of the adjacent stainless steel plates.
The advantage of this method is that the edges are seam welded together and then expanded to provide a reliable and durable moisture-proof construction.

Hereinafter, a detailed description will be given based on embodiments shown in the drawings.

Figure 1 is a front view showing the frame of this panel;
The figure is a cross-sectional plan view showing the internal structure of the panel. 1 is a rectangular bone frame, vertical and horizontal aggregates 2 and 3
An open web material, in the illustrated example, an expanded material is used. It has been confirmed that the amount of heat passing through the width direction of open web materials is extremely small, approximately 8% of that of general full web materials. Therefore, by adopting open web materials, the following
The formation of a heat bridge can be prevented as much as possible by passing the heat insulating material 13 between the outer wall panels 5 and 11. Note that a brace 4 for reinforcement is inserted into the bone frame as necessary.

Reference numeral 5 denotes a stainless steel plate stretched as an outer wall plate on the outside B of the bone frame 1, which serves both the exterior and moisture-proof function, and is made of a material that has at least an anti-glare property on the outer surface and can be welded. In the illustrated example, this stainless steel plate 5 consists of a large number of stainless steel plates 6 of a suitable narrow width arranged in parallel, with adjacent edges 7,
7 are airtightly joined by seam welding, and in order to absorb the thermal expansion and contraction of the stainless steel plate, the edges 7 of the stainless steel plate 6 bent outward are adjacent to each other. The top of the chevron 8 formed by the similar end edge 7 is sandwiched from both sides and seam welded, using a so-called expanded joint method.
In the illustrated example, the stainless steel plate 5 is attached to the bone frame 1 by attaching the tips of L-shaped fixtures 9, which have been protruded from the aggregate 1 at predetermined intervals, to the tops of the chevrons 8 during the above-mentioned joining. The method used is to sandwich and seam-weld three layers. Although this installation is not necessarily limited to the above, it is important to keep in mind that the stainless steel plate 5 and the fixture 9 should not be joined with bolts or bolts that would impair the airtightness of the stainless steel plate.
Avoid using rivets. Regarding both edges 10 of this stainless steel plate 5,
It is absolutely necessary to provide it in a shape that allows the expansion connection, and it is preferable to provide it so that it can be supported by welding the fixture 9 in the same manner as described above.

Reference numeral 11 denotes an inner wall plate stretched on the inside A of the bone frame 1, and is made of water-resistant plywood, corrugated steel plate, or the like. The inner wall board 11 is also fixed by fixtures 12 such as heat insulating bolts protruding from the aggregates 2 and 3 at appropriate intervals.

The distance between the stainless steel plate 5 and the inner wall plate 11 is
As will be clear from the description below, the thickness of the heat insulating material is determined as appropriate to obtain the required heat insulating performance depending on the purpose of use.

Reference numeral 13 denotes a heat insulating material such as glass wool filled in the space between the stainless steel plate 5 as the outer wall plate and the inner wall plate 11.

After filling the insulation material 13, asphalt 14 is applied to the peripheral end surface of the frame 1 to prevent moisture from penetrating into the insulation material 13 and deteriorating its performance when it is stored. It is better. In addition, in order to facilitate transportation and construction, the frame frame 1
It is recommended to protrude a lug 15 made of resin or the like at an appropriate location so that the lug 15 can be used when lifting with a crane or the like or when attaching to the steel frame of a warehouse.

The proposed exterior panel constructed as above has heat insulation,
When performing moisture proof construction, it is used as follows.

1 Regarding the joining of adjacent panels on the left and right.

The stainless steel plate 5 as an outer wall plate has adjacent edges 10 and 1, similar to the intermediate joint 18.
The top of the chevron 8 formed by 0 is seam welded and expanded to make it completely moisture-proof. On the other inner side, a connecting plate 16 spanning both inner wall plates 11, 11 is attached. At this time, the small space 17 formed between the left and right panels is filled with a heat insulating material by injecting urethane or the like.

2 Regarding the joining of panels arranged above and below.

As shown in the perspective view of FIG. 3, the chevron-shaped intermediate joint portion 18 of both the upper and lower panels (), () is tilted to either the left or right near the end of the stainless steel plate 5, and its edges 19, 19 are bent outward. Also, between the edges 19, 19, both upper and lower edges 2
Joint plate 2 with 1 and 21 bent outward as well
0 is placed, and the top of the chevron formed by the adjacent edges 19 and 21 is seam-welded in the same way as in the case of 1), and an expand connection is also performed in the vertical direction. The inside is exactly the same as 1), connecting plate 1
6 is stretched, and a heat insulating material such as urethane is injected into the space 22 between the end faces of the upper and lower panels.

If we use this panel to construct walls, roofs, etc. of low-temperature warehouses, we can: 1. Moisture proofing and insulation can be done at once;
Since the frame 1 is contained within the panel, the frame 1, which serves as a structural strength member, can be omitted, and since the anti-glare stainless steel plate 5 is used as the outer wall plate of the panel, this can be used as the exterior material. This does not mean that there is no need for an exterior covering such as slate, but rather an exterior that looks better than conventional ones of this kind and has significantly better weather resistance.

2. With 1) above, not only the moisture-proofing and insulation construction but also the construction procedure of the low-temperature warehouse itself is greatly simplified, resulting in significant reductions in construction period and construction costs.

3. Since open web material, which has a significantly smaller amount of heat passing through than full web material, is used as the aggregate of the panel, the formation of local heat bridges is eliminated as much as possible, and problems such as condensation on the exterior wall are eliminated.

4. The stainless steel plates covering the entire outside are airtightly joined together by seam welding, so complete moisture proofing can be achieved without the need to form a separate moisture proofing layer such as asphalt.

5 Moreover, since all the joints of the stainless steel plates are expanded joints, the expansion and contraction of the stainless steel plates exposed to direct sunlight does not pose a problem, and sufficient durability is guaranteed.

6 This stainless steel plate also acts as an external heat insulating material that reflects sunlight, and together with the effect of the heat insulating material filled inside, it exhibits excellent heat insulating performance.

As listed above, the exterior panel of this proposal is frozen,
This not only simplifies and inexpensively insulates and moisture-proofs refrigerated warehouses, but also simplifies and lowers the cost of constructing the framework, and is highly effective in increasing the reliability of construction.
