Description

[Detailed explanation of the idea] In recent years, external heat-insulated refrigerated warehouses, in which the outside of the building frame is covered with a heat insulating material, have become widely used.

As shown in Figure 1, this type of refrigerated warehouse has a heat insulating material b and a moisture-proof layer C layered on the outer surface of a concrete frame a, and a stud d that penetrates the moisture-proof layer C and the heat insulating layer C on the outside. Base material e1. e2 is installed.

Same base e1. Exterior material f is attached to e2.

In this way, in the conventional external heat insulation method refrigerated warehouse, a base material is required to support the exterior material, and the members for attaching this base material to the frame penetrate the moisture barrier layer and the heat insulating material. There is a risk of cold air leaking from this penetrating portion, and furthermore, this leaking cold air may cause condensation on the surface of the base material, causing corrosion.

Furthermore, since the thickness of the base material is included in the finished thickness of the refrigerated warehouse, there is a drawback that the finished thickness becomes thick.

This project was proposed in order to eliminate such defects, and in an external heat-insulated refrigerated warehouse where the outer surface of the building frame is successively layered with heat insulating material, heat insulating panels, and a moisture barrier layer, the structure is covered with mullions. is attached so as to be located inside the front moisture-proof layer, and a support piece for the rim for attaching the exterior material is attached to the outer surface of the mullion, and the moisture-proof layer and the heat insulation panel are supported by the support piece. This relates to the external heat insulation structure of a refrigerated warehouse.

As mentioned above, in conventional external heat-insulated refrigerated warehouses, the mullions that form the main part of the base material for mounting exterior materials are placed outside the moisture barrier layer, so the insulation thickness of the mullions is directly equal to the finished thickness. However, in this case, as mentioned above, the mullions are placed inside the moisture barrier layer, so they are not included in the finished thickness, and the finished thickness will be reduced. Therefore, the divided area is reduced and land can be used more effectively.

In addition, in the conventional refrigerated warehouse, although a heat insulating backing is interposed between the mullion and the studs for attaching it to the frame, as mentioned above, the girder frame attached to the mullion and the outside of the mullion Since the base material of the exterior material is placed outside the moisture-proof material, there remains a risk of corrosion due to condensation. The moisture in the moisture barrier layer is absorbed by the internal refrigerator, which greatly reduces the risk of corrosion caused by condensation on the base material of the exterior material. Corrosion countermeasures only need to be applied to the rim support piece and rim that are attached to the outside surface of the mullion.
This simplifies construction.

In addition, in this case, by arranging the mullions inside the moisture-proof material as described above, the insulation material to be layered on the outer surface of the building structure can be temporarily fixed using the mullions, which is different from the conventional method. This eliminates the need for temporary fixing materials such as molten asphalt, and eliminates burn injuries caused by asphalt.

Furthermore, in the present invention, the supporting piece of the frame provided on the outer surface of the mullion is also used for supporting the moisture-proof layer and the heat-insulating panel, and the support piece securely secures the heat-insulating panel and the moisture-proof layer to the outside of the frame. This proposal has many advantages, such as simplifying construction and reducing construction costs.

The present invention will be described below with reference to the illustrated embodiments.

1 is a concrete frame with square, circular,
Stud 2 having a heat insulating shape such as L shape, H shape or groove shape
The inner surface of the mullion 3 having a U-shaped cross section is attached to the flat attachment piece 2a provided at the tip of the mullion.

As shown in FIGS. 6 and 7, a screw punch 4 for attaching a rim support piece, which will be described later, is airtightly attached to the outer surface of the mullion 3, and at the same time, a screw punch 4, which will be described later, is attached to the side surface of the mullion 3, as shown in FIG. A date support piece 5 for supporting the outermost heat insulation panel is attached.

When installing the mullion 3, a heat-insulating annular backing 6a made of reinforced plastic or the like is fitted into the center hole drilled in the mounting piece 2a at the tip of the stud 2, and
A pair of backings 6b, 6b are arranged inside and outside of the mounting piece 2a, sandwiching the backing 6a, and a bolt 7 is passed through the inner flange of the mullion 3 and each of the backings, and a nut 8 is inserted.
By screwing and tightening, the mullion 3 is adiabatically connected to the stud 2.

The mullions 3 are attached to the outer wall surface of the frame 1 through studs 2 by about 1 inch.
A first layer heat insulating material 9A and a second layer heat insulating material 9B made of glass wool or the like are temporarily attached to the outer wall surface of the frame 1 using these mullions 3, which are arranged at intervals of mm.

Next, the outermost layer of heat insulation panel 10 is attached.

The heat insulating panel 10 has a wooden frame 10a filled with glass wool 10b, and a moisture-proof layer 11 layered on the outer surface in advance.

The heat insulation panel 10 has a date support piece 5 arranged in a mullion 3.
The top part is temporarily fixed with a nail 12 using a needle hole drilled in the upper date support piece 5.

(See Figure 5) Next, the insulation panels 10 are adjacent to each other vertically and horizontally.
A heat insulating material is filled in between, and a joint-attached moisture-proof layer 13 is attached.
Furthermore, an angular rim support piece 14 is attached to the outer surface of the mullion 3.
is attached via the screw punch 4 and nut 15 set in the mullion 3, and the heat insulating panel 10 is attached to the outside of the frame 1 together with the first layer insulation material 9A and the second layer insulation material 9B by the support piece 14. Fixed to the wall.

At this time, since the screw punch 4 penetrates the moisture-proof layer 13, this portion is subjected to moisture-proof treatment by the method shown in FIGS. 8 and 9.

First, a rubber backing 16 having a pressure bonding layer is attached to the outer surface of the mullion 3 so that the screw punch 4 protrudes into the central through hole 16a.

Next, a caulking material 1 is placed between the through hole 16a and the screw punch 4.
7 and screw the vertical piece of the furring support piece 14 with a screw punch 4.
and tighten the nut 15 to attach the support piece 1.
4 to mullion 3.

By completely attaching the furring support piece 14 to the mullion 3 in this way, the caulking material 17 completely fills the gap, and therefore the moisture barrier layer 11. Moisture-proof layer 13
, the caulking material 17, and the screw punch 4 are integrally continuous to form an air-tight moisture-proof surface.

Next, the horizontal furring 18 is connected to the horizontal piece of the furring support piece 14 by bolts 19 and nuts 20, and the exterior material 21 is attached to the horizontal furring 18.

In this case, since the mounting screw 4 of the furring support piece 14 attached to the mullion 3 penetrates the moisture barrier layer, the 11th
As shown in the figure, the position of the screw punch 4 penetrating the moisture barrier layer can be shifted from the position of the stud 2.

As is well known, the amount of heat transferred is inversely proportional to the length of the medium, so according to the embodiment described above, the amount of heat loss in the through screw portion is reduced, and the temperature difference between the screw punch and the surrounding outside air is reduced. is reduced, and the amount of condensation is reduced.
