DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a heat insulating inner wall foundation.

[0002]

2. Description of the Related Art Generally, in a steel-framed building, when the outer wall has a curtain wall structure, it is necessary to install a self-supporting base material and a heat insulating material when constructing the inner wall.

[0003] Conventionally, as shown in Fig. 8, a heat insulating material c is provided in a rectangular wooden base frame b, and a moisture-proof sheet d is provided on the inner side of the wooden base frame b which is the indoor side. To form a heat insulating inner wall panel a, and constructing the heat insulating inner wall panel a to form a heat insulating inner wall base. In this case, the heat-insulating inner wall panel a is configured such that a runner f having a groove-shaped cross section is fixed to a floor surface e, and the lower side is inserted into the runner f to be self-supporting directly below the beam g. Also, as shown in FIG. 9, the adjacent heat-insulating inner wall panels a are fixed to the wooden base frame b of one of the heat-insulating inner wall panels a with the screws j. Then, the two are fixed to each other by bending the other adjacent heat-insulating inner wall panel a and fixing it with a screw j. And, between the upper side of the heat-insulating inner wall panel a and the beam g, the fixing metal k fixed to the upper side of the wooden base frame b is fixed by the fixing piece m in a state of contacting the flange portion l of the beam g. .

[0004]

However, when the heat insulating inner wall panel a is constructed using the heat insulating inner wall panel a as in the prior art, the heat insulating inner wall panel a has the heat insulating material c in the wooden base frame b. Since the panel is formed in a clogged state, the wooden base frame b cannot be directly nailed to the floor surface e. Therefore, it is necessary to fix the runner f to the floor surface e and use the runner f to support the edge of the heat-insulating inner wall panel a, so that the work is troublesome. It will be. In addition, the adjacent heat-insulating inner wall panels a cannot be directly fixed to each other by nails, and the connecting metal fittings h must be used.

For this reason, it is conceivable to separately install the wooden base frame b, the heat insulating material c, and the moisture-proof sheet d on site without using the heat-insulating inner wall panel a. This causes inconvenience that the construction work becomes more troublesome than necessary.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for easily constructing a heat-insulating inner wall base material having an excellent heat-insulating effect.

[0007]

According to the present invention, there is provided a method for constructing a heat-insulating inner wall foundation, in which a moisture-proof sheet is attached to an outer surface of a rectangular wooden foundation frame. On the outer surface side of the sheet, outside the frame of the wooden base frame, in a state where the heat insulating inner wall panel on which the heat insulating material is attached is erected on the floor base material under the beam, from within the wooden base frame. By nailing, it is fixed to the wooden base frame or floor base material of the adjacent heat-insulating inner wall panel, and is fixed to the upper side of the wooden base frame below the beam via a fixing bracket.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a heat insulating inner wall foundation constructed by the heat insulating inner wall panel 1, and FIG. 2 shows a state in which construction has been completed by applying an inner wall finishing material 10 such as a gypsum board to the heat insulating inner wall foundation.

That is, in the method of applying the heat insulating inner wall base, the heat insulating inner wall panel 1 is fixed to the adjacent heat insulating inner wall panel 1 and the floor base material 61 with the nail 8 and is fixed to the beam 5 via the fixing bracket 9. To form a self-supporting heat insulating inner wall base.

As shown in FIGS. 3 and 4, the heat-insulating inner wall panel 1 has a moisture-proof sheet 3 stuck on the outer surface side of the wooden base frame 2 and a heat-insulating material 4 on the outer surface side of the moisture-proof sheet 3.
Is affixed.

The wooden base frame 2 comprises a vertical beam 21 and a horizontal beam 22.
Are framed into a rectangle. In addition, vertical beam 2
Between them, a plurality of middle crosspieces 23 parallel to the horizontal crosspieces 22 are provided to reinforce the entire wooden base frame 2. The wooden base frame 2 is provided with a wiring hole 20 in the middle cross member 23, and the wiring (not shown) can be freely arranged in the wooden base frame 2 using the wiring hole 20. .
In addition, at the position on the inner side of the wooden base frame 2 which is the indoor side and adjacent to the horizontal rail 22 on the upper side, the upper side of the wooden base frame 2 is flush with the inner side of the wooden base frame 2. Cross beam 22
At right angles to the above, a ceiling base mounting bar 24 is provided. Further, an airtight material 25 is provided along the vertical rail 21 at a position near the outer surface of one of the vertical rails 21 in the end surface of the wooden base frame 2.

The moisture-proof sheet 3 is attached to the entire outer surface of the wooden base frame 2. As the moisture-proof sheet 3, a polyethylene film on which aluminum is deposited can be used.

The heat insulating material 4 is attached to the outer surface of the moisture-proof sheet 3 and outside the wooden base frame 2. The heat insulating material 4 is stuck to the same size as the wooden base frame 2, but in a state where the heat insulating inner wall panel 1 is constructed, a gap between the horizontal rail 22 on the upper side of the wooden base frame 2 and the beam 5 is formed. In order to be able to cover sufficiently, it is stuck so as to protrude considerably upward from the horizontal rail 22 on the upper side of the wooden base frame 2. In addition, it is attached in the width direction so as to protrude from the wooden base frame 2 by the amount of the airtight material 25. As the heat insulating material 4, for example, a heat insulating material 4 made of high-density glass wool packaged in a film can be used. The heat insulating material 4 is fixed to the wooden base frame 2 by the studs 41 in a state of being in contact with the outer surface side of the wooden base frame 2. The heat insulating material 4 may be one in which a single heat insulating material 4 is attached to the wooden base frame 2 or a plurality of heat insulating materials 4.
May be attached.

Next, a method of constructing a heat insulating inner wall base using the heat insulating inner wall panel 1 configured as described above will be described.

First, prior to construction, a floor material 6, a floor covering material 61 and an outer wall panel 7 are constructed on a building frame constituted by beams 5 and ramen columns (not shown).
Then, as shown in FIGS. 1 and 2, first, the heat-insulating inner wall panel 1 is erected on a floor base material 61 directly below the beam 5. Then, from within the frame of the wooden base frame 2, the lower horizontal beam 2
2 is nailed to the horizontal beam 22 and the floor material 61
Fixed to

As shown in FIGS. 5 and 6, the vertical bars 21 are sandwiched between the vertical bars 21 of the heat-insulating inner wall panel 1 by nails 8 with a spacer 80 made of a piece of wood board interposed between the vertical bars 21. Fix it. At this time, since the airtight material 25 is interposed in the gap between the vertical beam members 21, a spacer having a width slightly smaller than the airtight material 25 is used as the spacer 80 in order to maintain the airtightness of the airtight material 25. . Also, the spacer 80
It may be a piece of wood board interposed only at the position of the nail 8, or may be a strip having a length corresponding to the length of the vertical crosspiece 21 and interposed in the entire gap.

Further, a fixing metal 9 is attached to the upper cross member 22, and the fixing metal 9 is fixed to the beam 5. As shown in FIG. 7, the fixing metal member 9 includes a groove-shaped metal member body 91 that is fitted into the horizontal rail 22 on the upper side of the wooden base frame 2.
A fixing member 92 that bites into the flange portion 50 of the beam 5 is connected by a bolt 93. The fitting main body 91 can be moved in the directions of the arrows A and B with respect to the fixing member 92 fixed to the beam 5 by the degree of rotation of the bolt 93, thereby adjusting the entrance and exit of the heat insulating inner wall panel 1. Thus, the heat-insulating inner wall panel 1 is constructed right below the beam 5 in a correct construction.

After the heat insulating inner wall panel 1 is constructed in this manner, an inner wall finishing material 10 such as a gypsum board is stuck on the surface of the wooden base frame 2. Further, the heat insulating material 4 is provided inside the beam 5. Further, a ridge 52 is provided on the ridge-mounting support member 24 of the wooden framing frame 2 via a ridge runner 51, and the ridge 52 is provided with a ceiling finishing material 5 such as a gypsum board.
3 is constructed. Further, a floor finishing material 62 such as a flooring material is stuck on the surface of the floor base material 61.

The heat insulating inner wall foundation thus constructed is constructed by using the heat insulating inner wall panel 1 in which there is no heat insulating material 4 in the frame of the wooden foundation frame 2 and the inside of this frame is a gap. By hitting the nail 8, the floor base material 61 can be easily obtained.
The heat-insulating inner wall panels 1 can be fixed on top of each other, or the adjacent heat-insulating inner wall panels 1 can be fixed to each other. Further, since the heat insulating inner wall panel 1 is directly fixed on the floor base material 61 without providing a runner or the like for regulating the heat insulating inner wall panel 1 on the floor base material 61, a portion orthogonal to the partition or the last one is provided. Even in the case where the mounting space is limited as in the case of constructing sheets, it can be easily positioned and fixed. Further, even in the case of a construction error, the fixing can be easily released by pulling out the nail 8, so that the construction can be easily redone.

In the heat insulating inner wall base formed in this way, since the wiring hole 20 is provided in the middle crosspiece 23 in the wooden base frame 2, the wiring is inserted through the wiring hole 20 to allow the wiring freely. Can be passed on to. In this case, since the moisture-proof sheet 3 and the heat insulating material 4 are attached to the outer surface side of the wooden base frame 2, wiring work can be performed without breaking the moisture-proof sheet 3 and the heat insulating material 4. Therefore, it is possible to prevent the heat insulation performance from being lowered by breaking the moisture-proof sheet 3 and the heat insulating material 4.

Furthermore, since the moisture-proof sheet 3 is deposited with aluminum, heat can be radiated into the air in the frame of the wooden base frame 2, and an excellent heat insulating effect can be obtained.

Further, when the construction is completed, a gap is usually formed between the wooden base frame 2 and the beam 5 because the fixing metal 9 is attached thereto.
Are heat insulating materials 4 so as to protrude above the wooden base frame 2.
Is attached, the gap can be closed by the heat insulating material 4. Therefore, a thermal bridge is not formed from the room to the outside, and excellent heat insulating properties can be maintained, and the work of putting the heat insulating material 4 into the gap in a later step can be eliminated. Also, since the heat insulating material 4 is stuck on the outer surface side of the wooden base frame 2, the heat insulating material 4 is stuck with a free width and thickness without considering that the heat insulating material 4 is to be accommodated in the frame of the wooden base frame 2. Therefore, it is possible to easily cope with heat insulation area divisions such as general areas and cold areas.

The wooden base frame 2 of the heat-insulating inner wall panel 1 in the present embodiment is not particularly limited to a wooden one but may be a steel one. However, in this case, it is necessary to take into consideration that a nail hole (not shown) or the like is formed in advance at a position where the nail 8 is driven so that the nail 8 can be driven and fixed.

[0025]

As described above, according to the present invention, a heat-insulating inner wall in which a moisture-proof sheet is stuck on the outer surface side, and a heat insulating material is stuck on the outer surface side of the moisture-proof sheet and outside the frame of the wooden base frame. Since the panel is used, the inside of the frame of the wooden base frame becomes a void. Then, by nailing from inside the voided frame of the wooden base frame, this heat-insulating inner wall panel is fixed to the wooden base frame or floor of the adjacent heat-insulating inner wall panel and fixed to the upper side of the wooden base frame. Since it is fixed under the beam via the metal fitting, it is possible to easily perform the construction only by using a nail except for the fixing metal fixed under the beam.

Except for the fixing fittings to be fixed under the beams, the heat-insulating inner wall panel is fixed on the floor base material only by using nails. There is no need to set it on Therefore, even when the last sheet is constructed, or when the mounting space is limited such as in a corner of a room or near a partition wall, the positioning and fixing can be easily performed. Further, even in the case of a construction error, the fixing can be easily released by pulling out the nail, so that the construction can be easily redone.
