Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating structure for a concrete building and a heat insulating method thereof, and more specifically, a heat insulating layer consisting of a cross member and a heat insulating material is formed on one side of a concrete wall of a building. On the other hand, the vertical members are assembled in a cross-shaped manner with respect to the horizontal members of the heat insulating layer, and an air layer is formed on the heat insulating layer by the vertical members, and a finishing material is attached on the vertical members. Pertains to the insulation structure of buildings and its insulation construction method.

Even if it is a concrete structure, if the walls and ceiling are constructed with an insulating structure, it will be less affected by the outside temperature, so the indoor temperature can be maintained at a comfortable temperature, and air conditioning costs can be greatly reduced. In order to save energy, it is desired to provide insulation structures for the walls and ceilings of buildings, as well as insulation construction methods. In addition, with this insulation, approximately 43% of the total heat loss is from the exterior walls, and 43% of the total heat loss is from the ceiling, roof, etc.
It is said to be 18.4%, and it is particularly important to improve thermal efficiency by eliminating the overwhelmingly large heat loss from the outer wall. However, in the conventional heat insulating structure, as shown in FIG. , and an exterior material 2 is attached on top of this heat insulating layer 4' with an air layer 3 interposed therebetween. Therefore, the insulation effect is incomplete and there is a lot of heat loss from the wall surface.

That is, when carrying out this exterior wall construction, short heat insulating boards 4 made of glass wool, rock wool, etc. are stacked on the side of the wall 1, and wires 5 are passed through these heat insulating boards 4, and the wires 5 are used to connect the heat insulating boards 4. hold. However, during construction, when the wire rod 5 is passed through the heat insulating board 4, a positional shift occurs, and a gap G is created between adjacent heat insulating boards 4. In addition, when the heat insulating plates 4 are arranged, gaps G are generated due to irregularities in the side edges of the heat insulating plates 4, and these gaps G
Since there is no heat insulation effect at all, the function as a heat insulation structure cannot be fully demonstrated. Moreover, since each heat insulating board 4 is fastened by a wire rod 5,
If the wire 5 comes off after construction, the heat insulating board 4 will fall down, and furthermore, the position will shift due to vibrations and the like.

The present invention aims to solve the above-mentioned drawbacks, and specifically, it is a concrete construction that has excellent heat insulation properties, in which heat insulating materials are arranged so that their side edges overlap, and each of these heat insulating materials can be reliably held. We propose an insulation structure for objects and its insulation construction method.

Hereinafter, the present invention will be explained in detail through its embodiments with reference to the drawings.

FIG. 5 is a perspective view showing an example of the arrangement, and FIG. 5 is a cross-sectional view of an example of a heat insulating board forming a heat insulating layer;
FIGS. 6a and 6b are cross-sectional views of an example of a longitudinal member incorporated into a part of the structure shown in FIG. 2, and FIG. FIG.

First, in FIG. 2, reference numeral 1 indicates a concrete structure forming the wall of a building, and horizontal members 6 are placed on the outer surface 1a of this concrete structure 1 at regular intervals, and screws, screws, etc. Attach by fixing it. As shown in FIGS. 2 and 3, a, b, c, and d, the cross member 6 is made of aluminum, steel, or the like and is constructed as a shaped or bent material. That is, in the example shown in FIG. 2, the stepped web edge 6b is interposed between the upper and lower flange edges 6a, 6a' that face each other,
The stepped portion a of the web edge 6b forms a storage portion above and below which is to accommodate the heat insulating material 8, etc., and the flange edge 6a abuts and is fixed to the concrete wall surface 1a.

The heat insulating material 8 disposed between the upper and lower cross members 6 is made of glass wool, rock wool, styrofoam, polyurethane, or the like. The heat insulating material 8, including such fibrous material, is laid out in a plate shape, and the side edges are inserted into each housing part of the stepped web edge 6b, and the cross member 6 and the heat insulating material 8 form a heat insulating layer. Form.

Next, on the outside of this heat insulating layer, vertical members 9 are incorporated into the horizontal members 6 in a cross-shaped pattern, and an air layer is formed between these vertical members 9. The vertical member 9 has parallel opposing flange edges 9a, 9a' and a web edge 9 connecting these.
b, which are arranged at regular intervals in a grid pattern at right angles to the cross member 6, and one flange edge 9a of the vertical member 9 is attached to the flange edge 6a' of the cross member 6 with a screw,
It is fixed with a screw or the like 10. Further, a finishing material 11 is provided on the other flange edge 9a' of the vertical member 9.

With this configuration, it consists of a heat insulating layer made up of the horizontal members 6 and the heat insulating material 8, an air layer formed between the vertical members 9, and a finishing material 11 on the outside air side.
It is insulated by two layers: a heat insulating layer and an air layer, and its effectiveness is enhanced.

Therefore, regarding the heat insulation structure according to the above configuration,
A more detailed explanation of its constituent members will be as follows.

First, the cross member 6 has the flange edges 6a, 6a' facing parallel to each other and the web edge 6 connecting these.
b, one flange edge 6a is in contact with the wall surface 1a of the concrete wall 1, and the other flange edge 6a' is in contact with the vertical member 9. The flange edge 6a is made wide and the flange edge 6a' is made narrow.

Moreover, the web edge 6b of the cross member 6 is not just a flat plate shape, but is structured as a step with at least one stepped portion a provided in the middle, and heat insulating materials 8 on both sides above and below the stepped portion a.
Two accommodating parts are formed to accommodate the . With this configuration, the heat insulating material 8 disposed in a plate shape has a step part a.
Since the two accommodating parts formed by the step part a are offset from each other, the heat insulating material 8 stretched into a plate shape can be prevented from shifting or tipping. Adjacent edges are overlapped without being butted. Therefore, no heat leaks or is given to this part, improving the heat insulation effect.

Further, if the cross member 6 has a stepped portion on the web edge and the upper and lower housing portions can be formed alternately by the stepped portion, then the structure shown in FIG.
It can be configured as b, c and d.
That is, these examples are constructed as bent ones, and among them, the shapes a and b in FIG.

Further, the cross member 6 shown in FIG. 3c has the best drainage when rainwater etc. enters, and the cross member 6 shown in FIG. 3b has the best effect of preventing displacement of the heat insulating material. Therefore, the shape of the cross member 6 can be determined by taking into consideration various environmental conditions surrounding the building, and it is possible to arrange not only one type of cross member but also a combination of two or more types of cross members as appropriate. It is also possible to set

Further, the heat insulating material 8 is spread out in a plate shape, but the upper and lower edges 8a, 8b and the left and right side edges 8c, 8d of the spread out heat insulating material 8 are staggered and stepped as shown in FIGS. 4a and 4b. and these side edges 8a, 8b, 8
c and 8d are staggered between adjacent heat insulating materials 8 so that they overlap each other.

Further, when the heat insulating material 8 such as glass wool or rock wool is made into a plate shape, it lacks regularity and the upper and lower edges 8a and 8b are easily deformed by the stepped portion a. Therefore, as shown in FIG. 5, the heat insulating material 8 stretched into a plate shape is surrounded by a combination of a metal or synthetic resin molded body 12 and a surrounding plate 113. By enclosing it in this way, the shape is maintained, and moisture and moisture from the air layer and the concrete structure 1 are not sucked into the heat insulating material 8, so that the heat insulating performance does not deteriorate.

Furthermore, instead of being constructed as shown in FIG. 2, the longitudinal members 9 may also be constructed as shown in FIGS. 6a and 6b. In the case of FIGS. 6a and 6b, the flange edge 9a also rests on the flange edge 6a' of the cross member 6 and on the finishing member 11 at the mounting edge 9a'.

Further, a heat insulating layer consisting of a cross member 6 and a heat insulating material 8;
The air layer formed between the vertical members 9 provides two layers of insulation, but if moisture such as rain enters between these layers, the temperature of the air layer becomes higher than the outside temperature, and the insulation layer function may be impaired. At this time, the air layer is configured to allow ventilation. In this case, as shown in FIG. 7, gaps P are formed above and below the finishing material 11 through which outside air enters and exits.

As explained in detail above, in the present invention,
There are no gaps between adjacent insulation materials, so
The insulation performance does not deteriorate. In addition, during construction, the insulation material can be installed in the form of a plate, but the side edges of these insulation materials are held by the upper and lower horizontal members, making it easy and safe to install finishing materials, especially in high places. This ensures that the insulation material remains in place even after installation, prevents it from shifting due to vibrations, deterioration and damage due to rainwater intrusion, and prevents functional deterioration.
