Hereinafter, a building renovation method according to the present embodiment will be described with reference to the drawings.
Drawing 1 is an explanatory view showing the wall panel installed in the building concerning this embodiment, (a) is a front view and (b) is a sectional view seen from the BB cut line in (a). .

The wall panel 1 includes a rectangular frame 2, an auxiliary bridging material 3, first face materials 4 and 5, and a heat insulating material 6.
The rectangular frame 2 includes a pair of vertical members 21 and 22 that are opposed to each other with a predetermined interval, and a pair of horizontal members that are horizontally stretched between the upper and lower ends of the pair of vertical members 21 and 22. 23, 24.
The auxiliary rod material 3 is a vertical rod material 31 and a horizontal rod material 32. The vertical rod 31 is stretched in the vertical direction at the approximate center of the horizontal members 23 and 24. A plurality of reed members 32 are provided, and are spanned between the vertical members 21 and 22 and the vertical reed member 31 in the horizontal direction with a predetermined interval in the vertical direction.
The first face materials 4 and 5 cover a pair of main surfaces of the rectangular frame 2 that face each other. Here, the main surface refers to the two surfaces having the largest area among the plurality of surfaces constituting the wall panel 1 or the side having the two surfaces.
The first surface materials 4 and 5 are fixed to the pair of surfaces on the main surface side of the rectangular frame 2 and the auxiliary collar material 3 by using an adhesive. Moreover, you may use fixing tools, such as a nail, as an auxiliary.
The first face materials 4 and 5 are made of structural plywood, but are not limited to this, and other face materials such as a plaster board may be adopted.
The heat insulating material 6 is accommodated in a space partitioned by the rectangular frame body 2 and the auxiliary rod material 3.

Next, the building repair method according to the present embodiment will be described.
For example, when the wall panel 1 is inundated due to a tsunami or flood and the internal state of the wall panel 1 is confirmed, the worker starts from the wall panel 1 assembled to the building to the first face material 4. Remove a part of.

  Here, the case where the part which opposes the lower two space divided by the rectangular frame 2 and the auxiliary | assistant bridging material 3 among the 1st surface materials 4 is demonstrated is demonstrated. In the following description, a portion to be removed from the first face material 4 is referred to as a removal portion 41. Note that a line L1 shown in FIG. This line L1 is also a cutting line when the first face material 4 is cut.

As shown in FIG. 2, the worker cuts a part of the first face material 4 along the side surface of the rectangular frame 2. Specifically, the operator cuts the first face member 4 along the side surfaces of the pair of vertical members 21 and 22 and the vertical rod member 31 using a cutting tool such as a handy router, for example, The first face member 4 is cut along the side surface of the cross member 24. Further, the worker cuts the first face material 4 so as to be along the side surfaces (lower surfaces) of the lower pair of horizontal support members 32. Thereby, since the part which covers the heat insulating material 6 is cut | disconnected among the removal parts 41, the said part is removed. Next, since the remaining part of the removed part 41 remains fixed to the vertical bar 31, the operator uses a grinding tool such as a disc sander to remove the remaining part of the removed part 41 and the vertical bar. The end portion on the surface side of 31 is cut and cut. A line L2 in FIG. 2 is a cutting line at this time. In addition, the heat insulating material 6 is removed beforehand at the time of grinding.
Moreover, in this embodiment, although the 1st face material 4 was cut | disconnected so that the side surface of a pair of vertical members 21 and 22 and the vertical rod material 31 and the side surface of a pair of lower horizontal rib material 32, a rectangular frame If it is a range inside the inner surface of the body 2, the location to be cut is not limited to this. However, by cutting along the side surface of the rectangular frame 2, the side surface can be used as a guide for a cutting tool (blade), and the cutting operation can be performed smoothly without preparing a separate guide.

  Next, as shown in FIG. 3, the operator confirms the internal state with the removed portion 41 and the heat insulating material 6 removed.

After confirming the internal state, the operator attaches the core material 7 to the side surfaces of the rectangular frame 2 and the auxiliary saddle material 3 exposed by removing the removal portion 41 as shown in FIG. Specifically, the operator attaches the core material 7 to the side surfaces of the pair of vertical members 21 and 22 and attaches the core material 7 to the side surfaces of the vertical rod material 31 using a fixture such as a nail 9 and an adhesive. . At this time, the other first face material 5 and the core material 7 are not fixed. Further, the surface of the core member 7 and the surfaces of the longitudinal members 21 and 22 are flush with each other.
After attaching the core material 7, the operator accommodates the new heat insulating material 6 in a space formed by the core material 7, the lower horizontal member 24, and the pair of lower horizontal members 32. Replace 6

  Thereafter, as shown in FIG. 5, the operator makes the second surface material with respect to the main surface side surface of the core material 7 so as to be substantially flush with the first surface material 4 remaining in the rectangular frame 2. 8 is attached using an adhesive and a nail 9. Since the second face material 8 is the same kind of face material as the first face material 4 and has substantially the same shape as the removed portion 41, the opening formed by removing the removed portion 41 is blocked. become. Further, if the first face member 5 is fixed to the core member 7 in addition to the longitudinal members 21 and 22, the bonding strength on the first face member 5 side becomes higher than the bonding strength of the second face member 8, which is not preferable. . Specifically, when a force is applied from a wall panel adjacent to the main wall panel 1, the force is concentrated on a portion where the bonding strength of the wall panel 1 is high, and there is a risk of damage from there. As described above, if the first face material 5 is fixed to the longitudinal members 21 and 22, but the second face material 8 is fixed only to the core material 7, the first face material 5 and the second face material The joint strength balance with 8 is almost the same, the stress concentration can be dispersed, and the possibility of breakage of the wall panel 1 can be suppressed.

As described above, according to the present embodiment, the removal portion 41 of the first face material 4 is cut along the side surface of the rectangular frame 2, and the end portion on the surface side of the vertical saddle material 31 is further cut. Thus, the removed portion 41 is removed from the rectangular frame 2. Thus, if the removal part 41 is removed, even if it is the state integrated in the building, the condition in the rectangular frame 2 can be confirmed.
Moreover, since the removal part 41 is removed by cut | disconnecting the edge part of the surface side of the vertical saddle member 31, there is no need to peel off the 1st face material 4 from the surface of the vertical saddle member 31, and the removal part 41 is easily made into a rectangular frame. It can be removed from the body 2.
And since the core material 7 is attached with respect to the side surface of the rectangular frame 2 and the vertical rod material 31 exposed by removing the removal part 41, the rectangular frame 2 and the vertical rod material 31 can be reinforced. .
In addition, since the second surface material 8 is attached to the main surface side surface of the core material 7 so as to be substantially flush with the first surface material 4 remaining in the rectangular frame 2, the second surface material 8. After the attachment, the main surface side of the rectangular frame 2 is closed with no level difference from the first face material 4. Thereby, it is possible to restore the state before the inside is confirmed, and the rectangular frame 2 can be reused.

Further, since the second face member 8 is fixed to the core member 7 with an adhesive, the second face member 8 can be fixed to the core member 7 with a simple operation.
In addition, since the heat insulating material 6 is replaced before the second face material 8 is attached, even if the heat insulating material 6 has become inundated due to, for example, a tsunami or a flood, the rectangular frame 2 has a building. Can be exchanged in the state of being incorporated into

  In the wall panel 1, the part that is submerged is the lower part, but since the removed part 41 includes a part that covers the lower part of the rectangular frame 2, the inside of the submerged part can be reliably confirmed.

Note that the present invention is not limited to the above embodiment, and can be modified as appropriate.
For example, in the above-described embodiment, the case where the end portion on the surface side of the vertical rod material 31 is cut is described as an example, but when the removed portion 41 is sized to straddle the horizontal rib material 32, Of course, the end portion on the surface side of the reed member 32 may be cut.
Moreover, although the vertical saddle member 31 and the horizontal saddle member 32 have been described as examples of the auxiliary saddle member 3, the auxiliary saddle member may be a saddle member disposed obliquely in the rectangular frame.
Moreover, although the wall panel 1 was illustrated and demonstrated in the said embodiment, it is possible to apply the structure of this invention also to a floor panel.
Furthermore, the structure of this invention is applicable also to the wall assembled by the frame wall construction method or the wooden frame construction method. In this case, a structure formed by a base (cross member), a beam (cross member), and a column (vertical member) erected between them is defined as a rectangular frame. Further, in this case, the studs and the trunk edge are used as auxiliary saddle materials.
In addition, the configuration of the present invention is mainly applied to various construction methods using wood. However, as long as the material to be cut (the first face material and the auxiliary hook material) can be cut, a rectangular frame or core is used. The material may be composed of a metal material.
