A mounting portion A3 for the skeleton B is formed, and a plurality of mounting holes A8 for lumber A1 are opened at the intermediate portion from the insertion portion A4 to the mounting portion A3 and above the mounting portion A3 to form the whole.

When mounting one or more lower and middle assembly metal fittings A2 on the back side of a timber A1 of one or more (two in the illustrated example, the case of two will be described below), FIG. After aligning the upper surface of the upper timber A1 with the lower corner of the bending protrusion A5 as shown in the figure, from the timber A1 mounting hole A8 to the timber A
Timber is nailed in 1 or bolt is screwed in and timber A on top
Then, the upper surface of the lower timber A1 is brought into contact with the lower surface of the upper timber A1, and a nail is driven or a bolt is screwed into the timber A1 from the mounting hole A8 for the timber A1 to attach it to the lower timber A1. The above timber mounting work or assembly metal fitting operation is repeated by the number of timbers A1 and the number of assembly metal fittings A2 that are attached to the back of two timbers A1.
A plurality of assembling metal fittings A2 are arranged in parallel in the length direction of 1 to obtain an exterior material A assembled and constructed on a wood panel.

In the lower and middle exterior materials A (see FIGS. 2 and 3), since the mounting portion A3 for the existing frame B is arranged above the upper timber A1, the mounting portion is used. The exterior material A is attached and fixed to the existing skeleton B. If the skeleton is made of concrete, an anchor bolt is used as the mounting bracket C, and if the existing skeleton B is a wooden structure or a simple construction type anchor bolt, Attach and fix using a metal fitting selected from nails, wood screws, bolts, etc. as the mounting metal fitting C. Further, since the insertion portion A4 is arranged on the back side of the lower member tree A1 in the exterior material A, it is attached and fixed to the connecting portion by the insertion portion A4 and the insertion piece A7 of the assembly metal fitting A2 and the existing skeleton B. Both of the attached parts A3 are hidden by the lower member tree A1 and cannot be seen from the front. When mounting one or more upper assembly fittings A2 on the back side of timber A1 of one or more (two in the illustrated example, the case of two will be described below), FIG.
After arranging the mounting hole A6 on the back side of the upper timber A1 as shown in the figure, etc., install nails or bolts into the timber A1 from the timber A1 mounting hole A8 and attach to the upper timber A1.
Next, the upper surface of the lower timber A1 is brought into contact with the lower surface of the upper timber A1, the insertion portion A4 is arranged on the back side of the lower timber A1, and then a nail is driven into the timber A1 from the mounting hole A8 for the timber A1 or a bolt is attached. Screw on and attach to the lower timber A1.

Such timber mounting work or assembly metal fitting work is repeated by the number of timbers A1 and the number of assembly metal fittings A2, and a plurality of metal fittings A2 are provided on the back side of the two timbers A1 in the longitudinal direction of the timber A1. An exterior material A that is arranged in parallel and assembled and assembled on a wood panel is obtained.

The upper exterior material A (see FIGS. 3 and 6)
Since the mounting portion A3 for the existing skeleton B is arranged on the back side of the upper timber A1, in order to mount it on the existing skeleton B using the mounting portion A3 and the mounting bracket C, the upper timber A
The bottomed hole A9 is formed at an appropriate depth from the surface of 1, and the mounting portion A3 is penetrated through the bottomed hole to drive the mounting bracket C into the existing skeleton B to fix it, but the skeleton is made of concrete. If it is made, an anchor bolt is used as the mounting metal C, and if the existing frame B is a wooden structure or a simple assembly type, a metal selected from anchor bolts, wood screws, nails, bolts, etc. is used as the mounting metal C.

By the way, when the lower part and the middle part exterior material A is arranged at the lower part of the existing frame B (the lower end part of the frame in FIG. 6), the mounting part A3 is used together with the assembly metal fitting A2.
Mounting hole A for timber A1 that is opened near the insertion part A4
8 or the mounting portion A3 (not shown) is used to drive the mounting bracket C into the existing frame B. Mounting hole A8 for timber A1
Or, when using a mounting hole A6 (not shown), since this mounting hole is arranged on the back side of the lower timber A1, a bottomed hole A9 is formed at an appropriate depth from the surface of the lower timber A1. The mounting hole 8 or the mounting portion A3 is penetrated through the bottomed hole, and the mounting bracket C (anchor bolt) is driven into the existing frame B to be mounted and fixed.

Next, the retrofitting method will be described. The existing frame B
An example of an existing structure (retaining wall of dam) (Fig. 6 (a)) will be described. The construction is performed from the lower part of the side wall surface of the existing building B toward the upper part, and the timber A1 of the lower and middle exterior material A is exposed at the lower part of the side wall, and the lower timber A1 is arranged on the lower side. Thus, the metal fitting A2 is arranged so that the insertion portion A4 is on the lower side and the insertion piece A7 is on the upper side.

Then, a mounting bracket C (anchor bolt) is driven into the existing frame B from the mounting hole A6 of the mounting part A3, and the bottomed hole A9 of the lower lumber A1 to the mounting hole 8 of the assembly bracket A2 or the mounting part A3 ( The mounting material C (anchor bolt) is driven into the existing frame B by penetrating (not shown) and the exterior material A is fixedly attached to the existing frame B.

When the exterior material A is mounted and fixed in this way,
A space D is formed by the height dimension of the bent protrusion A5 of the mounting portion A3 to form a heat insulating layer by an air layer. And
A wooden plug E is fitted and fixed in the bottomed hole A9, and a rubber or other packing material F is tightly fitted and fixed in the opening at the lower end of the gap D to close it.

By the way, another means for attaching and fixing the lowermost exterior material A which does not close the gap D with the packing material F is shown in FIG.
This will be described with reference to (b) and FIGS. 7 (a) and 7 (b). This mounting and fixing means uses the insertion portion A4 of the assembly metal fitting A2 of the exterior material A, but the mounting portion A3 of the assembly metal fitting A2 is mounted and fixed to the existing frame B with the mounting metal fitting C (anchor bolt). Is the same as above. The mounting and fixing means using the insertion portion A4 is a convex shape in a front view, and the engagement piece G1 of the connection fitting G having a substantially crank shape in a side view is engaged with the insertion portion A4 and the mounting piece G2 is attached to the existing frame. B is made to abut the surface of B and the connecting hole G3 opened in the mounting piece G2 is penetrated, and the existing frame B
The mounting metal fitting C (anchor bolt) is driven into, and the insertion portion A4 of the assembly metal fitting A2 of the lowermost exterior material A is connected and fixed to the existing frame B to complete the construction.

Next, another exterior material A is connected to the lowermost exterior material A which is attached and fixed, and is attached and fixed to the existing frame B. The second outermost exterior material A is such that the timber A1 is exposed, and the insert A4 of the assembly metal fitting A2 is placed on the lower side, and the insert A7 is placed on the top. Insert the insertion piece A7 of the assembly metal fitting A2 of the outermost packaging A into A4,
Connect the outermost packaging A to the second outermost packaging A,
Further, the mounting portion A3 of the assembly metal fitting A2 of the second exterior packaging material A is penetrated and the mounting metal fitting C (anchor bolt) is driven into the existing frame B to fix it.

The above-described mounting method is repeated until the exterior material A in the second stage from the top is attached, and the exterior material A is attached and fixed in order from the lower part of the side wall surface of the existing frame B to the upper part, and the side wall surface of the frame is fixed. Cover with a wooden exterior material A.

The uppermost exterior material A is connected by inserting the insertion piece A7 of the assembly metal fitting A2 of the second exterior material A into the insertion portion A4 of the assembly metal fitting A2, and then connecting the uppermost exterior material. After the mounting portion A3 of the assembly metal fitting A2 is penetrated from the bottomed hole A9 of the timber A1 on the upper part of A and the mounting metal fitting C (anchor bolt) is driven into the existing frame B to mount and fix it, the wood plug E is attached to the bottomed hole A9. And then fix it to finish the construction.

When the retrofitting method of the exterior material A is finished in this way, a space D is formed between the bottom side exterior material A and the top side exterior material A, and a space D is formed between the exterior body B and the air. A heat insulating layer is formed by the layers, so that the existing skeleton B is not a little protected from heat.

When the existing skeleton B is a concrete building,
If the above-mentioned retrofitting method is applied to the wall surface, it can be easily converted into a swanky log house-like structure.
When the existing building B is a wooden building, after using the assembly metal fittings A2 for the lower and middle exterior materials A as the assembly metal fittings A2 for the uppermost exterior material A, the above-mentioned retrofitting method is applied to the wall surface. Finishing is done by concealing the mounting portion A3 and the insert piece A7 that project upward from the upper timber A1 of the uppermost exterior material A with cutting material.

When the existing skeleton B has a simple assembly type structure, it can be installed by a retrofitting method substantially similar to the case of the above-mentioned wooden building. If the existing frame B is the building described above, the wall and the exterior material A
The heat insulating layer formed by the air layer in the void D formed between and has a significant structure.

[Effect] Since the present invention is constructed as described above, not only can the existing building body be a structure or a building, it can be constructed, but it can also be a concrete structure or a wooden structure and can be assembled by a simple structure (prefabricated structure). Well, it can be constructed and is useful. And when the retrofitting method is completed, the appearance of the concrete structure will be woody, so it will be in good harmony with the surrounding landscape, and in the case of concrete buildings or prefabricated simple structure buildings, the appearance will look like a log house. It changes and harmonizes in the same manner as above, and in both cases the landscape that has been impaired is remarkably improved, and in the case of the above-mentioned building, the atmosphere is remarkably improved, which makes the occupants' mood enjoyable and bright. In addition, since the exterior material preassembled with timber and the assembly metal fittings is used for the construction of the retrofitting method, if this exterior material is factory-produced in advance, an exterior material having uniform dimensions and shapes can be obtained.
The appearance is beautifully finished.
