Description

[Detailed description of the invention] The present invention provides a low-temperature warehouse, a wood dehumidifying drying room, a breeding house,
This invention relates to a construction method for buildings that maintain airtightness in buildings that require proper temperature maintenance and adjustment, such as bacteria houses and refrigerators/freezers.

Conventionally, the insulation materials used in this type of building structure may have sufficient insulation performance, but the insulation material becomes discontinuous because it is divided by the building structural materials, and heat bridges occur in these discontinuous parts. There is a drawback that airtightness is destroyed.

Furthermore, the insulation will be torn at the joints of the veneer insulation material, and the airtightness will be impaired.

The object of the present invention is to eliminate heat bridges in buildings that require these conventional airtight structures, seamlessly enclose the building with a heat insulating material, and obtain a building with high heat insulation effects.

Embodiments of the present invention illustrated in the drawings will be described below.

As shown in FIGS. 1 and 2, the heat insulating material used in the method of the present invention is a plurality of polymerized foamed polystyrene plates. The surfaces 3 and 4 of the expanded polystyrene plates 1 and 1' are pre-formed with octopus-shaped recesses 2 and 4 at the factory.
2' is recessed. Since the recesses 2 and 2' are formed by thermal processing, a hardened layer S is formed on the surfaces of the recesses 2 and 2'. The cross-sectional area of the entrance portions 2a of the recesses 2, 2' is smaller than that of the inner portions 2b.

As shown in FIG. 2, when the building structural material, e.g., the horizontal frame member 9, is located outside the foamed polystyrene plates 1, 1', the polystyrene plates 1, 1' are connected to the building structural member, e.g., the horizontal frame member 9, as follows. It is supported by the material 9.

First, fix the coupling screw bolt 12 to the horizontal member 9, and attach the first polystyrene plate 1 to the bolt 12.
Insert and secure.

In FIG. 2, 14 and 15 are washer nuts which are pressed against the front surface 3 and back surface 3' of the polystyrene plate 1 and which hold the polystyrene plate 1. 13 is a metal pipe. 11 is a washer nut loaded on the horizontal member 9. 10 is a welded portion, and 19 is a conical tip portion of the threaded bolt 12.

Next, stack the second polystyrene plate 1' on the first polystyrene plate 1, screw the coil spring nail 5 from the front side 4 of the second polystyrene plate 1' toward the back side 4', and tighten the tip of the nail 5. Make sure to stop halfway through the first polystyrene plate 1.

That is, the coil spring nail 5 does not penetrate the polystyrene plate 1. Of course, the positions of the coil spring nail 5 and the coupling screw bolt 12 are set apart.

Therefore, the heat insulating effect of the polystyrene plates 1, 1' is not impaired because heat bridges do not occur due to the nails 5 and bolts 12. Further, at this time, the positions of the seams 16 and 17 between the first polystyrene plate 1 and the second polystyrene plate 1' are shifted from each other. Also, if one polystyrene plate 1 is stretched vertically, the other polystyrene plate 1'
Leave it horizontally. (See FIG. 4) By doing this, the seams 16, 17 of the polystyrene plates 1, 1' are closed to each other, and heat bridges do not occur from the seams 16, 17. In this way, the polystyrene plates 1, 1' are arranged parallel to the horizontal member 9, so that the polystyrene plates 1, 1' are not separated by the building structural member 9 as in the prior art. Therefore, the polystyrene plates 1, 1' can form a continuous, seamless heat insulating layer that does not cause heat bridges.

Finally, the surfaces 3, 4 of the polystyrene plates 1, 1'
After noncombustible mesh materials 6, 6' are stretched on top, cement mortar 7, 7' is laminated. As a result, the cement mortar 7, 7' is the polystyrene plate 1,
The cement mortar 7, 7' and the polystyrene plates 1, 1' are filled up to the concave portions 2, 2' of the cement mortar 1', and the cement mortar 7, 7' is integrated with the polystyrene plates 1, 1', thereby imparting not only heat insulation properties but also strength as a structural material.

The point of imparting strength as a structural material has already been described in detail in JP-A-51-127183, so a detailed explanation will be omitted.

Next, by enclosing the pillar material 8 as shown in FIG. 1, the polystyrene plates 1 and 1' can be continuously formed as a heat insulating layer.

In the case of FIG. 1, the first polystyrene plate 1 is provided with a notch into which the pillar 8 is fitted, the pillar 8 is accommodated in the notch, and the two polystyrene plates 1,
1' so as to enclose the pillar material 8. The connection of the two polystyrene plates 1, 1' with the coil spring nails 5 is the same as in the case of FIG.

When the method of the present invention is used in a wood drying room as shown in Fig. 3, the horizontal members 9 for the ceiling are placed outside the polystyrene plates 1, 1', and the pillars 8 are placed on the polystyrene plates 1, 1' for the side walls. Contain it.

As described above, FIG. 2 shows a sectional view of the ceiling portion, and FIGS. 5 and 6 show sectional views of the wall portion.

In FIG. 2, reference numeral 2c indicates a steel truss land beam 21 in the ceiling portion that is an attachment member for the land beam 20.

In FIGS. 4, 5, and 6, reference numeral 18 denotes a flat plate brace, which is held together with the column 8 between the polystyrene plates 1 and 1'. Further, as shown in FIG. 4, the polystyrene plates 1 and 1' are stretched vertically and horizontally, respectively, and the seams 16 and 17 are closed with each other.

In this way, the building using the method of the invention is completely isolated from the outside by the polystyrene plates 1, 1'. Moreover, FIG. 7 shows a sectional view of the floor surface. In FIG. 7, 22 is a hardening material for the floor surface, 23 is a reinforcing bar, 24 is concrete, and 25 is chestnut stone. When constructing polystyrene plates 1 and 1' on the floor surface, the polystyrene plates 1 and 1' are connected with coil spring nails 5 with their joints 16' and 17' shifted in position, and placed on the waste concrete 24. Bye.

When three or more polystyrene plates are stacked one on top of the other, the third polystyrene plate may be joined to the second polystyrene plate 1' using a nail 5 with a coil spring. In this case as well, the seam is at a position offset from the seam 17 of the second polystyrene plate 1'.

Effects of the present invention: The heat insulating layer of a building obtained by the method of the present invention not only has extremely high airtightness without causing heat bridges, but also has the strength of the heat insulating layer itself as a structural material.

Polystyrene plates 1 and 1' are column members 8 and horizontal members 9
Since it uses a structure that is not divided by building structural materials such as, complete insulation is possible.

Two or more foamed polystyrene plates 1, 1' are stacked on top of each other, and the seams 16, 16', 17, 1
7' are alternated, and the joints 16, 16', 17, 1 of the two polystyrene plates 1, 1' hit the back sides of the foamed polystyrene plates 1, 1'.
7′ do not communicate with each other, therefore,
Heat bridges do not occur from the joints 16, 17 of the polystyrene plates 1, 1'.

Since the surfaces 3, 4 of the polystyrene plates 1, 1' are continuously coated with cement mortar 7, 7', the unit polystyrene plates 1, 1' continuously form an integral structural member, and the heat insulating layer Strong retention.

Since the tips of the screw bolt 12 and the coil spring nail 5 do not penetrate the polystyrene plates 1, 1', no heat bridge occurs from the screwed portion.
