[Problems to be solved by the invention]
However, in the case of the conventional heat insulating inner wall panel a, the heat insulating material c is provided in the frame of the wooden base frame b, and the moistureproof sheet d is provided on the inner surface side of the wooden base frame b. When wiring work such as outlet mounting is performed after construction, a part of the heat insulating material c and the moisture-proof sheet d must be broken, resulting in a disadvantage that the heat insulating effect is lowered.
[0005]
Moreover, since this heat insulation inner wall panel a is panelized in the state where the heat insulating material c was packed in the frame of the wooden base frame b, when fixing this heat insulation inner wall panel a to a floor surface, the wooden base frame b is It is not possible to fix nails directly to the floor. Therefore, on the floor surface, a mounting bracket such as a runner having a cross-sectional groove shape is fixed, and the mounting bracket must be used to support the edge of the heat insulating inner wall panel a. Inconvenient construction work will be caused.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
1 and 2 show an outline of the overall configuration of the heat insulating inner wall panel 1, and FIG. 3 shows a construction completion state of the heat insulating inner wall panel 1.
[0010]
That is, the heat insulating inner wall panel 1 has a moisture proof sheet 3 attached to the outer surface side of the wooden base frame 2 and a heat insulating material 4 attached to the outer surface side of the moisture proof sheet 3.
[0011]
The wooden base frame 2 is constituted by a vertical beam member 21 and a horizontal beam member 22 that are rectangularly framed. Further, a plurality of middle crosspieces 23 parallel to the horizontal crosspieces 22 are provided between the vertical crosspieces 21 to reinforce the entire wooden base frame 2. In the wooden base frame 2, wiring holes 20 are provided in the intermediate crosspiece 23, and wiring (not shown) can be freely taken into the wooden base frame 2 using the wiring holes 20. . Further, at the position on the inner surface side of the wooden base frame 2 and adjacent to the upper side crosspiece 22, it is orthogonal to the upper side crosspiece 22 so as to be flush with the inner side of the wooden base frame 2. Thus, a ceiling base mounting bar 24 is provided. Further, an airtight member 25 is provided along the vertical beam 21 at a position near the outer surface of one vertical beam 21 in the end surface of the wooden base frame 2.
[0012]
The moisture-proof sheet 3 is attached to the entire outer surface side of the wooden base frame 2. As this moisture-proof sheet 3, a polyethylene-deposited polyethylene film can be used.
[0013]
The heat insulating material 4 is affixed outside the frame of the wooden base frame 2 on the outer surface side of the moisture-proof sheet 3. This heat insulating material 4 is affixed to approximately the same size as the wooden underframe 2, but with the heat insulating inner wall panel 1 installed, the gap between the horizontal beam 22 on the upper side of the wooden underframe 2 and the beam 5 is maintained. It sticks so that it may be in the state which protruded from the horizontal crosspiece 22 of the upper side of the wooden base frame 2 considerably upwards so that it can fully coat | cover. Moreover, it sticks so that it may be in the state which protruded only the part of the airtight material 25 rather than the wooden base frame 2 also in the width direction. As this heat insulating material 4, the heat insulating material 4 made from a high density glass wool wrapped in a film can be used, for example. The heat insulating material 4 is fixed to the wooden base frame 2 with a ridge 41 in a state of being in contact with the outer surface side of the wooden base frame 2. This heat insulating material 4 may be one on which a single heat insulating material 4 integrated with the wooden base frame 2 is pasted, or may be one on which a plurality of heat insulating materials 4 are pasted.
[0014]
Prior to constructing the heat-insulated inner wall panel 1 constructed in this manner, the flooring 6 and the outer wall panel 7 are constructed in a building frame constituted by the beam 5 and the ramen pillar (not shown). Then, as shown in FIG. 3, first, the heat insulating inner wall panel 1 is erected on the floor base material 61 immediately below the beam 5. Then, the nails 8 are struck from the frame of the wooden base frame 2 to the horizontal rail 22 on the lower side, and the horizontal rail 22 is fixed to the floor base material 61.
[0015]
Further, as shown in FIGS. 4 and 5, the vertical beam members 21 are fixed with the nails 8 with a spacer 80 made of a wooden board piece interposed in the gap between the vertical beam members 21 of the adjacent heat insulating inner wall panels 1. At this time, since the airtight member 25 is interposed in the gap between the vertical beam members 21, a spacer 80 having a slightly narrower width than the airtight member 25 is used as the spacer 80 in order to maintain the airtightness of the airtight member 25. . Further, the spacer 80 may be a piece of wood board interposed only at the position of the nail 8, or corresponds to the length of the vertical beam member 21 and is in the form of a strip plate that is interposed in the entire gap. May be.
[0016]
Further, the fixing bracket 9 is attached to the upper side crosspiece 22, and the fixing bracket 9 is fixed to the beam 5. As shown in FIG. 6, the fixing bracket 9 includes a bracket main body 91 formed in a groove shape that fits into the crosspiece 22 on the upper side of the wooden base frame 2, and a fixing member 92 that bites into the flange portion 50 of the beam 5. Are connected by a bolt 93. And the metal fitting main body 91 can be moved to the arrow A and B direction with respect to the fixing member 92 fixed to the beam 5 by the rotation condition of the volt | bolt 93, and thereby the entrance / exit adjustment of the heat insulation inner wall panel 1 is performed. Thus, the heat insulating inner wall panel 1 is constructed immediately below the beam 5.
[0017]
After constructing the heat insulating inner wall panel 1 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. A heat insulating material 4 is provided inside the beam 5. Further, a field edge 52 is provided on the ceiling foundation mounting bar 24 of the wooden foundation frame 2 via a field edge runner 51, and a ceiling finishing material 53 such as a plaster board is applied to the field edge 52. Further, a floor finishing material 62 such as a flooring material is attached to the surface of the floor base material 61.
[0018]
Thus, according to this heat insulation inner wall panel 1, since there is no heat insulating material 4 in the frame of the wooden base frame 2, and the inside of this frame is a gap, the floor base material 61 can be easily formed by hitting the nail 8. It can be fixed on the top or adjacent heat insulating inner wall panels 1 can be fixed. Moreover, since the wiring hole 20 is provided in the intermediate crosspiece 23 in the space, the wiring can be freely inserted by inserting the wiring into the wiring hole 20. In this case, since the moisture-proof sheet 3 and the heat insulating material 4 are pasted on the outer surface side of the wooden base frame 2, the wiring work can be performed without breaking the moisture-proof sheet 3 and the heat insulating material 4.
[0019]
Further, since the moisture-proof sheet 3 is vapor-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.
[0020]
Further, when the construction is completed, a gap is usually generated between the wooden base frame 2 and the beam 5 because the fixing bracket 9 is attached, but this heat insulating inner wall panel 1 is more than the wooden base frame 2. Since the heat insulating material 4 is stuck so as to protrude upward, the gap portion can be closed with the heat insulating material 4. Therefore, a thermal bridge is not formed from the room to the outside, and excellent heat insulation can be maintained. Moreover, since this heat insulating material 4 is affixed on the outer surface side of the wooden base frame 2, a material having a free width and thickness is affixed without considering that it is housed 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.
[0021]
In addition, about the wooden foundation frame 2 of the heat insulation inner wall panel 1 in this Embodiment, it is not specifically limited to a wooden thing, The thing made from steel may be sufficient. However, in this case, it is necessary to consider that a nail hole (not shown) or the like is formed in advance at a position where the nail 8 is to be driven so that the nail 8 can be driven and fixed.
[0022]
【The invention's effect】
As described above, according to the present invention, the moisture-proof sheet is pasted on the outer surface side of the wooden base frame, and the heat-insulating material is pasted on the outer surface side of the moisture-proof sheet and outside the wooden base frame. The inside of the wooden base frame is a gap. Therefore, at the time of wiring work such as outlet mounting, the wiring can be routed in the wooden base frame without breaking the moisture-proof sheet or the heat insulating material. In addition, when fixing this heat-insulated inner wall panel to the floor surface or when fixing it to an adjacent panel, it is possible to directly fix the nails from the frame of the wooden base frame to the floor surface or the adjacent wooden base frame. It can be done easily.
[0023]
Moreover, since the heat insulating material is stuck outside the frame of the wooden base frame, the thickness and size of the heat insulating material can be set regardless of the size of the wooden base frame. Therefore, if the heat insulating material is pasted to a size that protrudes around the wooden base frame, the outer side of the wooden base frame can be covered with the heat insulating material without gap when the heat insulating inner wall panel is constructed. It is possible to eliminate the formation of a thermal bridge at the base frame portion. Further, by changing the thickness and type of the heat insulating material, it is possible to easily cope with the heat insulating area classification such as a general area or a cold area.
