Description

【0001】
【産業上の利用分野】
本発明は建築、構築物の既存外装面を新規外装材で改修するための構造に関するものであり、さらに詳しくは、古くなった既存の躯体、既存外装面の強度を向上する補強板をテンション付加構造として配設して、建物の強度を向上させる改修構造に関するものである。
【0002】
【従来の技術】
従来、この種の外装等の改修としては、古くなった既存の外装をすべて撤去して、既存の躯体や胴縁等の外装下地材に新規外装材を形成する構造や、既存の外装材上に直に、もしくは、新規胴縁や防水シートを介して新規外装材を取り付ける構造が一般的であった。
【0003】
【発明が解決しようとする課題】
しかしながら、このような改修では古くなった既存の外装と新規外装材を交換することや、傷んだ既存の外装上に新規外装材を形成して、既存外装を隠蔽することの技術思想のみであり、古くなった建物の既存の躯体、あるいは既存外装を補強し、強度を向上させる技術思想は全く考慮に入れられていなかった。このため、改修後の建物の躯体には負担が係り、強度的に弱く、特に耐震性に極端に劣り、地震等の発生で新規外装材が脱落したり、躯体の破損、建物の崩壊等の被害が発生することもあった。
【0004】
【課題を解決するための手段】
本発明はこのような欠点を除去するため、建築、構築物の既存外装面を新規外装材で改修する構造において、改修する既存外装面上に斜めに伸びる帯状の補強材が配設固定され、補強材は水平面と傾斜面からなる板材の傾斜面に切り込みを形成した固定部材の切り込みに端部が挿入され、水平面が躯体に固定された後に傾斜面が斜め方向に固定具により躯体に打設され、補強材上に乾式外装材からなる新規外装材が形成されている改修構造を提案するものである。
【0005】
【実施例】
以下に図面を用いて本発明に係る改修構造の一実施例について詳細に説明する。図1、図2は本発明に係る改修構造の特に外壁の改修構造の代表例を示す説明図であり、Aは既存建物の躯体、Bは既存外装、Cは補強材、Dは固定部材、Eは新規外装材、Fは基礎、Gは役物である。
【0006】
躯体Aは図2に示すように、垂直方向に伸びる主柱1、間柱2、および水平方向に伸びる横架材である土台3、軒桁もしくは妻梁4とから構成される一般的なものである。勿論、これらは木造構造の建物での名称であり、鉄骨造構造ではこれらの位置に、H型鋼材、角形鋼材、C型鋼材、等が配設されているものである。なお、図2では便宜上既存外装Bを一点鎖線で示し、新規外装材Eは省略して示してあるものである。
【0007】
また、既存外装Bは躯体Aの外側面に例えば木摺、防水シート、ラスシート、モルタル壁材の順に配設、施工されたモルタル壁(湿式壁材)からなるもの、あるいはコンクリート壁構造、S造、RC造、SRC造、もしくは、躯体A上に金属系サイディング材、窯業系サイディング材、ALCパネル、タイル、塩ビ押出サイディング材、等の乾式外装材を施工した壁構造、等の一種からなるものである。勿論、屋根に使用する場合には、既存外装Bは金属系屋根材、瓦、新生瓦、スレート屋根、等よりなるものである。
【0008】
補強材Cは図4に示すようなものであり、少なくとも土台3、軒桁もしくは妻梁4、後記する胴差し5の少なくとも1本以上に沿って斜めに配設するものであり、その本数は改修する建物の損傷具合や、必要強度によって任意に設計できるものである。また、建物の外周外装面の全てを一本の長い補強材Cにより、はち巻き状に被覆して補強することもできるものである。この場合、土台3、軒桁もしくは妻梁4、あるいは胴差し5、等の横架材が破損している場合には、特に有効である。勿論、既存外装B面毎に1本の補強材Cを横架材に沿って配設することもできる。
【0009】
また、補強材Cは既存外装B上に土台3から軒桁もしくは妻梁4にかけて斜めに1本以上交差して配設されるものであり、既存外装Bを介して躯体Aを構成する少なくとも土台3、軒桁もしくは妻梁4に、釘、スクリュービス、テクス、アンカー、アンカーボルト等の固定具αによって取り付け、古くなった躯体Aおよび既存外装Bの強度を向上する筋交いの機能を有するものである。
【0010】
また、補強材Cは図4に示すように、例えば幅狭の長尺薄板状の鋼材、カラー鋼板、アルミ鋼板、等の各種金属薄板やこれらの複合体、あるいは繊維強化樹脂等の金属帯状物もしくは線状物からなるものであり、特に金属製とした際には、引っ張り力に強く金属特有の粘りもあることから最も好ましいものである。また、補強材Cの板厚は0.5mm〜4.0mm位とし、なるべく薄くすることで後記する新規外装材Eの施工の邪魔にならないようにするのが好ましいものである。
【0011】
固定部材Dは図5(a)、(b)((a)図のイ−イ線端面図)、(c)((a)図のロ−ロ線端面図)に示すような短尺材であり、ステンレス鋼板、鋼材、カラー鋼板、等の各種金属板よりなり、テンションを付加する補強材Cよりも強度(引っ張り強度)があるものを使用するものである。その形状としては、水平面状の水平面6と、水平面6の先端を上方に傾斜(角度θ)して突出した傾斜面7と、傾斜面7に形成した切り込み8と、切り込み8により形成された狭持片9、狭持片10と、固定部材D固定用の固定孔11、テンション付加孔12、固定孔13とから形成されたものである。
【0012】
固定部材Dは図3に拡大して示すように、補強材Cの4隅端部をテンションを付加した状態で固定できるようにしたものである。その固定方法としては、まず、図7(a)に示すように切り込み8に補強材Cの端部を挿入して固定孔11を躯体Aに固定し、次に、図7(b)に示すようにテンション付加孔12に固定具αを斜めに挿入して躯体Aに打設し、図7(c)に示すようにテンションを付加した状態で固定する。最後に、固定孔13を躯体Aに固定具αを介して固定するものである。勿論、4隅を同じように固定するものである。なお、図5に示す固定部材Dは補強材Cの端部に向かって左側のものであり、右側の固定部材Dとしては、図5に示す固定部材Dの左右対称に形成した固定部材Dを使用するものである。
【0013】
なお、固定部材Dの傾斜面7の角度θは約45゜以上が施工性、テンションのかかり具合として好ましいが、角度を変化させても良い。勿論、角度を大きくするとテンションのかかりが大きくなり、角度を小さくするとテンションのかかりが小さくなるものである。
【0014】
新規外装材Eは金属系サイディング材、もしくは、窯業系サイディング材、塩ビ押出サイディング材、ALCパネル、タイル、金属系パネル、等からなる乾式外装材からなるものであり、特に図6に示すような、金属薄板からなる表面材14と金属薄板もしくはシート状物からなる裏面材15とで、合成樹脂発泡体からなる芯材16をサンドイッチした金属系サイディング材が軽量で強度にも優れ、なおかつ、施工容易な点から好ましいものである。勿論、屋根に使用する場合には、新規外装材Eは金属系屋根材、瓦、新生瓦、スレート屋根、等よりなるものである。
【0015】
また、新規外装材Eは図1に示すように補強材C上から直接、釘等の固定具αを介して躯体Aに順次取り付けられ、建物の外表面を多い、意匠性、断熱性、防音性、防火性等をさらに向上させるものである。勿論、新規外装材Eを形成する際には、水切り、止縁、出隅、入隅、スタータ、ジョイナ、等の役物Gを必要に応じて配設するものである。
【0016】
次に、本発明に係る改修構造の施工方法について簡単に説明する。先ず、図1に示すように、モルタル壁等からなる既存外装B上に図4に示すような長尺帯状の補強材Cを土台3と軒桁もしくは妻梁4にかけて固定具αを介して固定すると共に、角線上にクロスさせるように配設し、固定部材Dによりテンションを付加して固定し、既存の躯体Aおよび既存外装Bの強度を補強し、向上させる。
【0017】
さらに、補強材C上に金属系サイディング材からなる新規外装材Eを釘等の固定具αを用いて躯体Aに順次取り付け、施工を完了するものである。勿論、外装全体を改修するには、水切り、止縁、出隅、入隅、スタータ、ジョイナ、等の役物Gを必要に応じて配設するものである。
【0018】
以上説明したのは、本発明に係る改修構造の一実施例であり、図8〜図29に示すような改修構造としたり、改修ための部材を用いることもできる。
【0019】
すなわち、図8〜図14は本発明に係る改修構造の外壁改修のその他の実施例を示す説明図であり、図8、図9は途中に胴差し5が形成された2階建て以上の建物の改修構造を示すものである。なお、図8、図9においては既存外装Bを便宜上一点鎖線で示したものであり、新規外装材Eは省略して示してある。

【0021】
さらに、図12は補強材Cと新規外装材Eとの間に胴縁Iを設けると共に、その空間に断熱層Jを形成した例である。
【0022】
なお、図12に示す断熱層Jは、構造全体の断熱性能、気密性能の向上や補強材Cを金属製とした際に、温度差により結露が発生するのを防止するものである。断熱層Jの形成は、例えばポリウレタンフォーム、ポリイソシアヌレートフォーム、フェノールフォーム、塩化ビニルフォーム、ポリエチレンフォーム、ポリスチレンフォーム、ユリアフォーム等、もしくはこれらに無機軽量骨材、無機繊維等の無機材を混入した物、等の合成樹脂発泡体や、石膏ボード、ロックウールボード、ガラス繊維、シージングボード、等の無機材ボード等のボード状パネルを順次張り合わせて形成することもできるが、特に現場吹き付け発泡型の合成樹脂発泡体を用いるのが好ましいものである。
【0023】
すなわち、断熱層Jを現場吹き付け発泡型の合成樹脂とした際には、その素材としては硬質のウレタンフォーム、もしくは難燃2級・難燃3級(JIS−A−1321)合格品のフェノール+イソシアネート+難撚材を用いることもできる。勿論、ノンフロンの合成樹脂を用いると共に、フェノールにより難燃化を図ったものである。また、断熱層Jを現場吹き付け発泡型の合成樹脂とすることで、狭い場所や、端部にも吹き付け発泡できるので、より一層の気密化と断熱化を図ることができ、さらに、施工が容易で、コストの節減になるものである。
【0024】
図13は補強材Cの端部をプレートKにてさらに補強した改修構造であり、プレートKは金属板材よりなるものである。さらに、図14は新規外装材Eとして縦張りのものを使用した例である。
【0025】
図15〜図17は補強材Cの変形例であり、舌片、凹凸リブ、エンボス、等を施して補強材Cの強度を向上させたものである。
【0026】
図18(a)〜(c)、および図9は固定部材Dのその他の実施例を示す斜視図であり、図18(a)は右側の固定部材D、図18(b)は両端に切り込み8形成した固定部材D、図18(c)は補強材Cの幅よりも大きい切り込みを中央に形成した固定部材Dである。また、図19は切り込み8を左右に形成し、台形状の部分17を固定具αと一緒に打設することにより、ルーズホールの固定孔11部分でテンションが付加されるようにした固定部材Dである。
【0027】
図20(a)〜(f)は新規外装材Eに用いられる乾式外装材のその他の例を示すものであり、図20(a)〜(c)は金属系サイディング材、図20(d)は塩ビ押出サイディング材、図20(e)、(f)は窯業系サイディング材の断面形状を示すものである。
【0028】
図21〜図29は屋根に本発明に係る改修構造を形成した場合の実施例である。すなわち、図21、図22は施工状態を示す一部切り欠き斜視図、図23〜図25は施工順序を示す一部切り欠き斜視図、図26は施工状態を示す断面図、図27〜図29はその他の実施例を示す斜視図である。なお、図27〜図29においては既存外装Bを便宜上一点鎖線で示し、新規外装材Eは省略して示したものである。
【0029】
【発明の効果】
以上説明したように本発明に係る改修構造によれば、従来の欠点を解決し、▲1▼少なくとも異なる横架材同士を連結するように既存外装面から補強材を斜めに配設固定することで、既存の躯体強度と外装強度を向上させ、建物は水平荷重、垂直荷重の両方に強くなり、地震等の振動や、台風等の外圧に強い構造となる。▲2▼補強材を固定部材でテンションを付加できるために、補強材の機能を十分に活用できる。▲3▼加工が簡単な切り込みにより、補強材を簡単に固定してテンションを付加できる。▲4▼既存外装を解体する必要がないので、施工工数を省略できると共に、工期を大幅に短縮することができ、しかも施工中の居住に何等支障を来さない。▲5▼既存外装上に新規外装材を形成するので、施工が簡単でコストを節約できる。▲6▼既存外装と新規外装材の2重外装構造となり、断熱性、防音性、防火性、防水性に富む構造となる。等の特徴、効果がある。

[Industrial applications]
The present invention relates to a structure for repairing an existing exterior surface of a building or a building with a new exterior material, and more particularly to an old existing frame, a reinforcing plate for improving the strength of the existing exterior surface, and a tension-added structure. It relates to a renovation structure that is arranged as a building to improve the strength of the building.
[0002]
[Prior art]
Conventionally, the renovation of this type of exterior has been to remove all the existing exterior that is old, and to form a new exterior on the existing base material such as the existing skeleton and rim, or on the existing exterior. In general, a structure in which a new exterior material is attached directly or through a new body edge or a waterproof sheet has been used.
[0003]
[Problems to be solved by the invention]
However, such renovation is only a technical idea of replacing the old exterior with a new exterior material, or forming a new exterior material on a damaged existing exterior to conceal the existing exterior. The technical idea of reinforcing the existing frame or the exterior of an old building and improving its strength was not taken into account at all. For this reason, the structure of the renovated building is burdened, and the strength is weak, especially the seismic resistance is extremely inferior, new exterior materials may fall off due to the occurrence of an earthquake, damage to the structure, collapse of the building, etc. Damage could have occurred.
[0004]
[Means for Solving the Problems]
According to the present invention, in order to eliminate such drawbacks, in a structure in which an existing exterior surface of a building or a building is renovated with a new exterior material, a belt-shaped reinforcing material that extends diagonally on the existing exterior surface to be renovated is disposed and fixed, and the reinforcement is performed. The end of the material is inserted into the notch of the fixing member, which has a notch formed on the inclined surface of the plate material consisting of the horizontal surface and the inclined surface, and after the horizontal surface is fixed to the skeleton, the inclined surface is obliquely driven into the skeleton by the fixture. The present invention proposes a renovation structure in which a new exterior material made of a dry exterior material is formed on a reinforcing material.
[0005]
【Example】
Hereinafter, an embodiment of a repair structure according to the present invention will be described in detail with reference to the drawings. 1 and 2 are explanatory views showing a typical example of the renovation structure according to the present invention, particularly a renovation structure of an outer wall, where A is a frame of an existing building, B is an existing exterior, C is a reinforcing material, D is a fixing member, E is a new exterior material, F is a foundation, and G is an accessory.
[0006]
As shown in FIG. 2, the frame A is a general structure composed of a main pillar 1, a stud 2, which extends in a vertical direction, and a base 3, eaves girder or girder 4, which is a horizontal member extending in a horizontal direction. is there. Of course, these are names in a wooden structure building, and in a steel frame structure, an H-shaped steel material, a square steel material, a C-shaped steel material, and the like are arranged at these positions. In FIG. 2, for convenience, the existing exterior B is indicated by a dashed line, and the new exterior material E is omitted.
[0007]
In addition, the existing exterior B is composed of a mortar wall (wet wall material) which is disposed and constructed on the outer surface of the frame A in the order of, for example, a wood slide, a waterproof sheet, a lath sheet, and a mortar wall material, or a concrete wall structure, an S structure. , RC construction, SRC construction, or a type of wall structure constructed with dry exterior material such as metal siding material, ceramic siding material, ALC panel, tile, PVC extruded siding material, etc. on the skeleton A It is. Of course, when used for a roof, the existing exterior B is made of a metal roof material, a tile, a new tile, a slate roof, or the like.
[0008]
The reinforcing material C is as shown in FIG. 4 and is disposed obliquely along at least one or more of the base 3, the eaves girder or the girder 4, and the trunk 5 to be described later. It can be arbitrarily designed depending on the damage condition of the building to be renovated and the required strength. In addition, the entire outer peripheral surface of the building can be reinforced with a single long reinforcing material C by covering it in a spiral shape. In this case, it is particularly effective when the horizontal members such as the base 3, the eaves girder or the girder 4, or the trunk 5 are damaged. Of course, one reinforcing member C can be disposed along the horizontal member for each of the existing exterior B surfaces.
[0009]
Further, one or more reinforcing materials C are disposed on the existing exterior B so as to intersect at least one diagonally from the base 3 to the eave girder or the girder 4, and at least the base constituting the frame A via the existing exterior B is provided. 3. It is attached to the eaves girder or the girder beam 4 with fixing tools α such as nails, screw screws, tex, anchors, anchor bolts, etc., and has a brace function to improve the strength of the old frame A and the existing exterior B. is there.
[0010]
As shown in FIG. 4, the reinforcing material C is, for example, a thin and long thin plate-shaped steel material, various metal thin plates such as a color steel plate, an aluminum steel plate or the like, a composite thereof, or a metal strip such as a fiber reinforced resin. Or, it is made of a linear material, and particularly when made of metal, it is most preferable because it has a strong tensile force and has the inherent stickiness of metal. Further, it is preferable that the plate thickness of the reinforcing material C is about 0.5 mm to 4.0 mm, and it is preferable to make the thickness as thin as possible so as not to disturb the construction of the new exterior material E described later.
[0011]
The fixing member D is a short material as shown in FIGS. 5 (a) and 5 (b) (a sectional view taken along the line II in FIG. 5 (a)) and FIG. Yes, it is made of various metal plates such as a stainless steel plate, a steel material, and a color steel plate, and has a strength (tensile strength) higher than that of the reinforcing material C to which tension is applied. As the shape, a horizontal surface 6 in a horizontal plane, an inclined surface 7 protruding by inclining the tip of the horizontal surface 6 upward (angle θ), a cut 8 formed in the inclined surface 7, and a narrow formed by the cut 8 It is formed of a holding piece 9, a holding piece 10, a fixing hole 11 for fixing the fixing member D, a tension adding hole 12, and a fixing hole 13.
[0012]
As shown in FIG. 3 in an enlarged manner, the fixing member D can fix the four corners of the reinforcing member C in a state where tension is added. As a fixing method, first, as shown in FIG. 7A, the end of the reinforcing material C is inserted into the cut 8 to fix the fixing hole 11 to the frame A, and then, as shown in FIG. As described above, the fixing tool α is obliquely inserted into the tension adding hole 12 and driven into the frame A, and is fixed in a state where the tension is added as shown in FIG. Finally, the fixing hole 13 is fixed to the frame A via the fixing tool α. Of course, the four corners are similarly fixed. The fixing member D shown in FIG. 5 is the one on the left side toward the end of the reinforcing member C. As the right fixing member D, a fixing member D formed symmetrically to the fixing member D shown in FIG. Is what you use.
[0013]
The angle θ of the inclined surface 7 of the fixing member D is preferably about 45 ° or more in terms of workability and tension, but the angle may be changed. Of course, increasing the angle increases the tension, and reducing the angle decreases the tension.
[0014]
The new exterior material E is a metal-based siding material, or a dry-type exterior material including a ceramic-based siding material, a PVC extruded siding material, an ALC panel, a tile, a metal-based panel, and the like. A metal siding material in which a core material 16 made of a synthetic resin foam is sandwiched between a surface material 14 made of a thin metal plate and a back material 15 made of a thin metal plate or a sheet-like material is lightweight, has excellent strength, and is constructed. This is preferable from the viewpoint of easiness. Of course, when used for a roof, the new exterior material E is made of a metal roof material, a tile, a new tile, a slate roof, or the like.
[0015]
Further, as shown in FIG. 1, the new exterior material E is sequentially attached to the skeleton A directly from above the reinforcing material C via a fixing tool α such as a nail, so that the outer surface of the building has many exterior surfaces, design properties, heat insulation properties, and sound insulation. And fire resistance are further improved. Of course, when the new exterior material E is formed, accessories G such as a drainer, a cut edge, an outer corner, an inner corner, a starter, a joiner, and the like are provided as needed.
[0016]
Next, a method for constructing the renovation structure according to the present invention will be briefly described. First, as shown in FIG. 1, a long strip-like reinforcing material C as shown in FIG. 4 is fixed on a base 3 and an eaves girder or a girder 4 via a fixture α on an existing exterior B made of a mortar wall or the like. At the same time, they are arranged so as to cross on a square line, and are fixed by adding tension with a fixing member D, thereby reinforcing and improving the strength of the existing frame A and the existing exterior B.
[0017]
Further, a new exterior material E made of a metal-based siding material is sequentially attached to the frame A using a fixing tool α such as a nail on the reinforcing material C, and the construction is completed. Needless to say, in order to repair the entire exterior, the accessory G such as a drainer, a bevel, an outside corner, an inside corner, a starter, a joiner, and the like is provided as needed.
[0018]
What has been described above is an embodiment of the renovation structure according to the present invention. The renovation structure shown in FIGS. 8 to 29 or a member for renovation can be used.
[0019]
8 to 14 are explanatory views showing another embodiment of the outer wall repair of the repair structure according to the present invention, and FIGS. 8 and 9 show a two-story or more building in which a trunk 5 is formed in the middle. This shows the renovation structure of the building. In FIGS. 8 and 9, the existing exterior B is shown by a dashed line for convenience, and the new exterior material E is omitted.
[0020]
FIG. 10 shows an example in which a waterproof sheet H is interposed between the reinforcing material C and the new exterior material E to improve waterproof performance. FIG. 11 shows that a body edge I serving as a mounting base for the new exterior material E is interposed between the reinforcing material C and the new exterior material E, and a ventilation method is employed by utilizing the space to prevent the occurrence of dew condensation and the like. It is an example of a structure.
[0021]
FIG. 12 shows an example in which a body edge I is provided between a reinforcing material C and a new exterior material E, and a heat insulating layer J is formed in the space.

In addition, the heat insulating layer J shown in FIG. 12 is intended to improve the heat insulating performance and airtight performance of the entire structure and to prevent the occurrence of dew condensation due to a temperature difference when the reinforcing material C is made of metal. The heat insulating layer J is formed, for example, by mixing a polyurethane foam, a polyisocyanurate foam, a phenol foam, a vinyl chloride foam, a polyethylene foam, a polystyrene foam, a urea foam, or the like, or an inorganic material such as an inorganic lightweight aggregate or an inorganic fiber. Objects, such as synthetic resin foam, or gypsum board, rock wool board, glass fiber, sizing board, etc., can be formed by sequentially laminating board-like panels such as inorganic material boards. It is preferable to use a synthetic resin foam.
[0023]
That is, when the heat-insulating layer J is made of an in-situ sprayed foam-type synthetic resin, the material is hard urethane foam or phenol + which has passed the second and third flame retardant (JIS-A-1321) standards. Isocyanate + a non-twist material can also be used. Needless to say, non-fluorocarbon synthetic resin is used, and flame retardancy is achieved by phenol. In addition, since the heat insulating layer J is made of a synthetic resin of a foaming type sprayed on site, it can be blown and foamed even in a narrow place or at an end portion, so that it is possible to achieve further airtightness and heat insulation, and furthermore, the construction is easy. This saves cost.

【The invention's effect】
As described above, according to the modified structure according to the present invention, the conventional disadvantage can be solved, and (1) at least the reinforcing member is obliquely arranged and fixed from the existing exterior surface so as to connect at least different horizontal members. Thus, the existing frame strength and exterior strength are improved, and the building is resistant to both horizontal loads and vertical loads, and has a structure that is resistant to vibrations such as earthquakes and external pressures such as typhoons. {Circle over (2)} Since the reinforcing member can be tensioned by the fixing member, the function of the reinforcing member can be fully utilized. {Circle around (3)} With a notch that is easy to process, the reinforcement can be easily fixed and tension can be added. (4) Since it is not necessary to dismantle the existing exterior, the number of construction steps can be reduced, the construction period can be significantly reduced, and there is no hindrance to living during construction. (5) Since a new exterior material is formed on the existing exterior, construction is easy and cost can be saved. (6) A double exterior structure consisting of an existing exterior and a new exterior material is provided, resulting in a structure that is rich in heat insulation, soundproofing, fireproofing, and waterproofing. There are features and effects.
