Description

  The present invention relates to a building structure having a heat insulating structure.

In general, marine products such as kelp are collected from the sea and dried before being provided to the market. Drying of marine products is carried out not only by sun drying but also in a drying room. In recent years, drying rooms have been widely used from the viewpoint of shortening drying time.
In order to efficiently use the heat in the room, it is desirable that this type of drying room has a heat insulating structure between the inside and outside of the room, and is disclosed in Patent Document 1 as a building structure having a heat insulating structure. Is known.

  As shown in FIG. 5, the heat insulating structure 100 for a building structure shown in Patent Document 1 has a roof structure formed between a portion indicated by a reference symbol X on the indoor side and a portion indicated by a reference symbol Y on the outdoor side. The steel board 102, 102... Is interposed between the base material 101 of the roof, the insulation board 103 made of foam plastic is attached, and the insulation board 103, 103 is jointed between the insulation boards 103, 103, and then the insulation board. A waterproofing material 104 is applied or sprayed on the surface 103.

  According to the heat insulating structure 100, since the space P and the heat insulating board 103 exist outside the base 101, the temperature transmission between the outdoor X side and the indoor Y side can be effectively cut off, and a high heat insulating effect can be obtained. I can do it.

  However, in the above heat insulating structure 100, the heat insulating board 103 absorbs moisture adhering to the inside thereof, so that mold or the like is generated on the heat insulating board 103, and the heat insulating performance is deteriorated and durable due to corrosion of the heat insulating board 103. There was a problem that the deterioration of sex occurred.

  Moreover, when the heat insulation structure 100 is applied to the marine product drying room as described above, the room X has a high temperature and a high humidity, so moisture easily enters the walls and the roof. There is a problem that the moisture that has entered the inside cannot be discharged to the outside. That is, in the heat insulating structure 100, when the internal moisture enters the space P through the heat insulating structure 100, the inside of the space P is a closed space, so that the moisture is absorbed by the heat insulating board 103 and effectively exposed to the outside.

  As a method for constructing the drying shed 1 described above, it is possible to construct the drying shed 1 as a whole or by constructing the thermal insulation structure 2 afterwards for a hut that does not have an existing thermal insulation structure. . Hereinafter, a method for constructing the heat insulating structure 2 will be described later.

  First, as shown in FIG. 1, the heat insulating material 9 is fastened so as to cover the entire area from the upper part 3 b of the foundation 3 slightly above the ground surface GL to the inner panel 17 to the upper end of the inner panel 17. In this case, the heat insulating material 9 is fastened to a housing such as the eaves girder 15 and the pillar 13 by a fastener (not shown). In addition, when the heat insulating material 9 is fastened, if a gap is generated between the base portion 3 and the base 7 of the hut, a filling process is performed.

  Next, after arranging the waterproof material 10 inside the heat insulating material 9, the plurality of vertical trunk edges 30 shown in FIG. 3 are fastened substantially vertically with a predetermined interval in the horizontal direction. Then, the interior material 12 is attached to the vertical trunk edge 30, and the ventilation layer 11 is formed between the heat insulating material 9 and the interior material 12.

  Next, as shown in FIG. 1, the heat insulating material 9 is fastened to the rafter 19 inside the roof 5, and the heat insulating material 9 is provided so as to cover the entire inner surface of the roof 5 closely.

  Further, similarly to the heat insulating structure 2 provided on the outer wall 8, a sheet-like waterproof material 10 is arranged on the surface of the heat insulating material 9 provided on the inner side of the roof 5, and the heat insulating material 9 provided with the waterproof material 10. The vertical body edge 30 is fastened on the interior, and the interior material 12 is attached so as to cover the entire inner surface of the roof 5. As described above, the heat insulating structure 2 can be provided in an existing cabin.

Next, the method for drying kelp by the drying shed 1 and the operation of the heat insulating structure 2 will be described.
As shown in FIG. 4, the wet kelp K is hung on the crosspiece 35 installed in the drying chamber R1, the hot air generator 32 provided in the control chamber R2 is operated, and hot air is blown into the drying chamber R1 from the fan 34. The temperature in the drying chamber R1 is increased. At this time, the fan 40 installed in the drying chamber R1 is operated to distribute the hot air into the drying chamber R1.

In this case, even if the temperature of the outdoor 1b is low, since the indoor 1a and the outdoor 1b of the drying shed 1 are insulated by the heat insulating material 9, the temperature of the indoor 1a is maintained.
When the moisture contained in the suspended kelp K starts to evaporate due to the temperature rise in the drying chamber R1, the fan 38 of the exhaust hole 37 is operated.

When the fan 38 is operated, the indoor 1a of the drying shed 1 has a negative pressure, so that the indoor 1a is naturally supplied with air from an air supply hole (not shown) due to an atmospheric pressure difference from the atmospheric pressure of the outdoor 1b of the drying hut 1. .
At this time, the ventilation layer 11 communicates with the indoor 1a at the lower end 12a of the interior material 12, communicates with the exhaust hole 37, and communicates with the indoor 1a. The air 1a is discharged from the exhaust hole 37.

  Thus, according to the drying shed 1 having the heat insulating structure 2 according to the present invention, the ventilation layer 11 is interposed between the heat insulating material 9 provided with the waterproofing material 10 and the interior material 12, and the inside of the ventilation layer 11 is disposed. Since the air can be circulated, it is easy to evaporate and discharge moisture between the surface of the waterproof material 10 and the interior material 12, and the heat insulating material 9 and the indoor 1 a of the dry hut 1 that becomes hot and humid. The interior material 12 is less likely to be corroded by mold or the like, and the heat insulating effect is hardly lowered.

Moreover, since corrosion due to mold or the like can be prevented, the effect of maintaining the drying chamber clean and enhancing the durability of the heat insulating material 9 and the interior material 12 can be obtained.
Moreover, the effect that it is hard to produce a dew condensation between the heat insulating material 9, the foundation 3, and the outer wall part 8 with the air containing moisture is acquired.

Furthermore, if a phenol resin foam having a lower thermal conductivity than other foams such as rigid urethane foam is used as the heat insulating material 9, high heat insulating performance can be obtained, and the thickness of the heat insulating material 9 can be suppressed to be indoors. 1a space can be secured.
Moreover, since the heat insulating material 9 can be reduced in weight, it is easy to carry and install the heat insulating material 9 to the construction site, and the work can be efficiently performed. There is an effect that reduction can be achieved, and further, an effect that the fixed load of the drying shed 1 can be reduced.

  In the above-described embodiment, an example in which the present invention is applied to a kelp drying shed has been described. However, the present invention is not limited to this application, and may be applied to a clothing drying chamber and other various drying chambers.
