Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for renovating the exterior walls of buildings such as houses, stores, etc., such as solid board walls, steel plate walls, slate walls, mortar walls, etc., with new exterior wall boards.

Conventionally, for example, as a method for renovating the exterior wall of a house, the existing exterior wall to be renovated was removed and structural materials such as studs and rims inside the wall were removed.
A method is known in which a new external wall board is attached to the structural member after exposing it to i3.

However, this conventional method has the drawbacks of requiring time and effort to remove the existing exterior wall, and causing great inconvenience to the occupants of the house from the time the existing exterior wall is removed until the new exterior wall is installed. .

The present invention aims to provide a method for renovating an exterior wall that eliminates the drawbacks of the conventional method, and the present invention will be described in detail below with reference to the drawings in which the method was used to renovate an existing wooden wall.

Referring to Figure 1, the prefabricated wall has wooden studs 1 as wall structural materials.
It has a structure in which a wooden siding board 2 is attached to the outside surface of the structure.

First, the waterproof paper 3 is attached to the outer surface of the siding board 2 .

Next, a base frame 4 with a rectangular cross section for installing a new external wall board having a length approximately equal to the height of the existing wall...
・Abut against the position corresponding to the stud 1 on the outer surface of the waterproof paper 3 with the nails 5 ・ facing vertically, and
・・・・・・Substrate bone 4・・・・・・Waterproof paper 3, clapboard 2
...... and stud 1... and fix it.

Next, the new exterior wall board 6... is attached to the base frame 4...
Install it horizontally on the outside surface of...

As shown in the fourth diagram, the outer wall board 6 has a top plate 8 made of an aluminum alloy plate etc.
are joined with adhesive etc., and the nail holes 9 are attached to the upper end of the top plate 8.
. . . and a downwardly directed groove 10 is provided in the lower part thereof, and the lower end of the top plate 8 is bent to the back side of the heat insulating plate 7, and the tip thereof is provided with a locking protrusion. It was formed in 11th.

The method of constructing the exterior wall panels 6 is as follows.

First, in this example, as shown in the second figure, the liner 13 is attached to the base 12, and on the outer surface of this liner, as shown in the fifth figure, nail holes 15 are drilled in the upper part and recessed in the lower end. Aluminum alloy plate-shaped starting material 14 with grooves 16 formed therein
Attach by nailing.

Next, the locking protrusion 11 of the first exterior wall board 6 is locked in the groove 16 of the starting material 14, and the nails 17 are inserted through the nail holes 9 into the base bone. 4. Fix the outer wall board 6 by driving it into place.

Next, the locking protrusion 11 of the second exterior wall board 6 is engaged with the groove 10 of the first exterior wall board 6, and the second exterior wall board 6 is attached by nailing in the same manner as above. Fix it to the underlying bone 4.

Thereafter, the outer wall panels 6 are sequentially attached upward in the same manner.

18 is the foundation and 19 is the foundation.

At the top of the existing wall, as shown in Figure 6, an aluminum alloy circumferential edge 20 with a roughly J-shaped cross section is attached in advance to the outer surface of the base frame 4 as shown in Figure 3. Insert the upper end of the uppermost outer wall board 6 into the J-shaped groove of the circumferential edge 20, and drive nails 21... from the upper end of the mounting plate 6 into the circumferential edge 20 and the base bone 4... Fix it with.

25 is an eave, and 26 is a prefabricated surround.

As shown in the first diagram, the side ends of the outer wall panels 6 are fixed to the base bone 4 by fixing a circumferential edge 22 having the same structure as the circumferential edge 20, and inserting the circumferential edge 22 into the J-shaped groove of the circumferential edge 22. Each outer wall board 6・
Insert the side end of...

The ends of both sides of the external wall boards at the inside corners are placed in the large corner accessory 23, as shown in Figure 8, and the ends of the outside wall boards of both sides of the outside corners are placed into the outside wall boards 23, as shown in Figure 9. Place it in Yakumo 24.

In addition, in fixing the base frame 4, if the structural members such as studs and rims are steel frames, it is sufficient to use a method of drilling and tapping holes in the structural members and fixing them with screws.

Further, in the case of a pre-fabricated wall, three mortar walls, etc., and the base is covered with the pre-fabricated wall, the liner 13 may be passed through the base 18 of the pre-fabricated wall and fixed with nails or the like.

In addition, when attaching the waterproof paper 3, if the existing wall is a wall surface that cannot be fixed to the waterproof paper, such as a mortar wall, the base frame 4.
It is sufficient to attach it to the outer surface of...

According to the method of renovating the exterior wall of a building of this invention, there is no need to remove the existing exterior wall, so construction work can be omitted, the construction period can be greatly shortened, and there is no need for residence during the renovation work. There is an orientation point that does not cause any problems, and in addition, during construction, the base ribs are fixed to the structural materials to maintain the desired strength, and the external wall boards are made of long materials and are placed in a direction perpendicular to the base ribs. Because it can be installed, the spacing between the base ribs can be set arbitrarily, and it is possible to install the base ribs at appropriate positions depending on the position and strength of the structural members of the existing wall, which makes it difficult to install external wall boards. Therefore, the exterior wall panels can be reliably and easily attached with sufficient strength without losing its strength, and its value for U.S. use is extremely high.

In addition, the gap between the new and old exterior walls is closed by the liner and starter material, resulting in a good appearance.Since the starter material is attached to the mounting surface of the liner in the same direction, there is no unevenness in the front-rear direction, and the new exterior wall is attached to the starter material. The board can also be installed in the same manner as the starting material without requiring any special considerations such as the installation position and spacing of the base ribs, and no unevenness will occur.

Note that the renovated outer wall obtained by the method of the present invention can also be combined with an existing wall to form a double wall to enhance heat insulation, soundproofing, and other effects.
