旧設の古い外壁材の外側に新しい外壁材を展装するよう
にした改装されに建物に関する。[Detailed Description of the Invention] The present invention relates to a renovated building in which, when renovating the exterior wall material of an existing building, a new exterior wall material is placed outside the old exterior wall material.

な支持金具を介して新しい外壁材を取付けるようにした
施工例が提案されている。In buildings that were constructed a long time ago, over the years, the exterior wall materials have weathered, corroded, cracked, and become stained due to wind and rain, vibrations, and air pollution, making the building's appearance unsightly and causing the exterior wall materials to peel off. This could result in extremely dangerous situations such as falling, so it would be necessary to replace the old exterior wall materials with new ones, but conventionally, when renovating this, the old exterior wall materials would be stripped off from all over the building and the new exterior wall materials would be placed on top. Because the method used was to attach the old exterior wall materials, there were drawbacks such as making a lot of noise when stripping off the old exterior wall materials, causing pollution such as scattering dust into the surrounding area, and requiring a long period of time to renovate. Recently, a construction example has been proposed in which the old exterior wall material is left in place without being removed from the building frame, and the new exterior wall material is then attached (via appropriate supporting metal fittings).

ところで、新築建物と違って改装建物の場合には、室内

装作業を行わなければならないため、できるだけ迅速容
易に改装できる構造でなければならない。By the way, unlike newly constructed buildings, renovated buildings must have a structure that allows them to be renovated as quickly and easily as possible, as people live and work indoors, and renovation work must be carried out while there are many people coming and going. Must be.

また新しい外壁材を古い外壁材に展装するために、まず
古い外壁材に適当間隔に支持金具を固着し、これら支持
金具間に多数の長尺な支持骨枠を固定し、これら支持骨
枠を取付基準として、これに新しい外壁材を展装するよ
うにしている。In addition, in order to install new exterior wall materials on old exterior wall materials, first, support metal fittings are fixed to the old exterior wall materials at appropriate intervals, and a large number of long support frame frames are fixed between these support metal fittings, and these support frame frames are fixed. The new exterior wall material will be installed using this as the installation standard.

したがって新しい外壁材を迅速容易に展装するためには
、その取付基準となる多数の支持骨枠を支持金具に簡易
にかつ強固に取付けるようにしなければならない。Therefore, in order to quickly and easily deploy new exterior wall materials, it is necessary to easily and firmly attach a large number of supporting frameworks, which serve as attachment standards, to the supporting metal fittings.

のために塞ぐことははなはだ危険である。However, in the past, when attaching a long supporting frame between supporting metal fittings provided at appropriate intervals, both were fixed with ports and nuts. The bolt must be gripped with one hand and the nut gripped with the other hand, which makes fixing the bolt cumbersome, and it is extremely dangerous to have both hands occupied, especially when working at heights.

かけて取付けなければならなかった。Furthermore, the surface of old exterior wall materials has become uneven or distorted due to long-term use, or the old support frames and metal fittings used to attach them to the building frame are stuck inside the old exterior wall materials. Therefore, in order to install a new exterior wall material on this old exterior wall material, it is necessary to absorb the above-mentioned irregularities and distortions, avoid obstacles such as the old support frame and mounting hardware, and replace the new support hardware with the old one. It had to be installed from the exterior wall material to the building frame.

するようにしていた。For this reason, conventionally, a pair of L-shaped fittings (angle fittings) or U-shaped fittings (
In addition to using an L-shaped or U-shaped support bracket or support frame, a long hole is provided in the L-shaped or U-shaped support bracket or the support frame. Adjustments are made vertically or horizontally when viewed from the front, but when adjusting in the forward direction (indoor/outdoor direction), a part of the old exterior wall material is ground down and a recess is created. At the concave part, the L-shaped support fittings are fixed to the old exterior wall material with anchor bolts, and these adjustment operations absorb the unevenness and distortion of the old exterior wall material, and 1.
．． The new exterior wall material was installed in an orderly manner while avoiding the obstacles mentioned above.

目的に反することになる。However, in this conventional structure, as mentioned above, a part of the old exterior wall material is ground to particularly adjust the viewing direction. In other words, by laying new exterior wall materials on top of the old exterior wall materials without any polishing, this goes against the original purpose of shortening the construction period and preventing work pollution.

たものである。Furthermore, the present invention does not require any sharpening of the old exterior wall material, and the support frame can be installed by simply finding the support frame that will serve as the installation standard for the new exterior wall material, and screwing the support fittings in accordance with the installation position in the expected direction. It can be installed in a fixed position, making it easier to renovate the exterior wall.

On the other hand, the horizontal support frame 17 is formed of a channel frame material having a U-shaped cross section facing the road, and screw pockets 19 having a substantially U-shaped cross section are provided on the bottom surface of the side and both side surfaces of the frame side.
, 20 over the entire longitudinal direction, the old exterior wall material 1
Insert the screw 21 into the horizontally elongated hole 18 of the support fitting 16 in line with the horizontal support frame 17 to be installed at a fixed position on the outside of the room. By screwing the screws 21 into the support fittings 16, the horizontal support frame 17 can be fixed at a desired fixed position on the front and back surfaces.

めて容易に、かつ高所作業を安全に行うことがてきる。As described above, according to the present invention, supporting metal fittings are fixed at appropriate intervals to the old exterior wall material that remains without being removed from the building frame, and a long supporting frame is arranged between these supporting metal fittings. In a renovated building where new exterior wall materials are installed outside of this supporting frame, long holes for screw insertion are opened in the supporting metal fittings in the prospective direction, and the supporting frame is replaced with a frame with a roughly U-shaped cross section. and a screw pocket with a substantially U-shaped cross section is formed on each frame side of the U-shaped frame material over the entire length thereof,
The supporting frame is fixed to the supporting metal fittings by screwing screws from the long holes for screw insertion into the screw pockets on the frame side opposite to the long holes, so even if the old exterior wall material is worn out over time, its surface may deteriorate. Even if unevenness or distortion occurs, the support frame can be fixed by moving the screws for fixing the support frame along the long holes for screw insertion made in the support fittings and the screw pockets formed in the support frame. The direction and position can be accurately fixed in the fixed position, and by inserting the screws from the long holes of the support bracket into the screw pockets of the support frame, all you have to do is tighten the screws with one hand. The supporting frame can be fixed to the supporting metal fittings, and the fixing work can be performed extremely easily and work at height can be performed safely.
