Description

本発明は、例えばビル等の既設建築物に外壁材等として使用されているALC(軽量気泡コンクリート)パネル、特に長方形状のALCパネルを縦長に配置した既設ALC縦壁パネルが経年劣化などにより取付部の耐力が低下した場合あるいは耐震性能を向上させる場合などに適用する補強構造に関する。   In the present invention, for example, an ALC (lightweight cellular concrete) panel used as an external wall material in an existing building such as a building, in particular, an existing ALC vertical wall panel in which rectangular ALC panels are arranged vertically is attached due to deterioration over time. The present invention relates to a reinforcing structure that is applied when the proof stress of a part is reduced or the seismic performance is improved.

上記のような建築物は過去の大きな地震を教訓にして耐震性能が強化され、建物躯体に対するALCパネルの取付構造すなわち取付構法も時代の変遷を受けて耐震性能を強化した構法に移行してきている。例えばALC縦壁パネルの取付構法の1つである挿入筋構法は、過去に多く施工され、かつ下記特許文献1のような改良もなされてきたが、耐震性能が必ずしも充分ではない等の理由で2002年に廃止された経緯がある。   Buildings such as those described above have been improved in seismic performance based on lessons learned from past major earthquakes, and the mounting structure of ALC panels on the building structure, that is, the mounting construction method, has also shifted to a construction method that has improved seismic performance in response to the changing times. . For example, the insertion muscle construction method, which is one of the ALC vertical wall panel attachment construction methods, has been constructed in the past and has been improved as shown in Patent Document 1 below, but the seismic performance is not necessarily sufficient. There is a history of being abolished in 2002.

図7は上記従来のALC縦壁挿入筋構法の施工例を示すもので、建物躯体であるH形鋼等よりなる梁材1の上部にアングル材等よりなる下地鋼材2を取付け、その下地鋼材2の側面に溶接等で固着したタテカベプレート3にALCパネル4を載置すると共に、そのタテカベプレート3に形成した鉄筋挿通穴3a内および横方向に隣り合うALCパネル4・4の縦目地J1内に目地鉄筋5を配設し、その目地鉄筋5の周囲の上記縦目地J1内にモルタル6等を充填して固化させた構成である。   FIG. 7 shows a construction example of the above conventional ALC vertical wall insertion reinforcement method. A base steel material 2 made of an angle material or the like is attached to an upper part of a beam material 1 made of an H-shaped steel or the like which is a building frame, and the base steel material. The ALC panel 4 is placed on the vertical plate 3 fixed to the side surface of the steel plate 2 by welding or the like, and the vertical joints of the ALC panels 4 and 4 adjacent to each other in the reinforcing bar insertion hole 3a and in the horizontal direction are formed in the vertical plate 3 The joint rebar 5 is arranged in J1, and the vertical joint J1 around the joint rebar 5 is filled with mortar 6 or the like and solidified.

ところが、上記のように横方向に隣り合うALCパネル4・4の縦目地J1内にモルタル等を充填して固化させるものは、地震等の際にALCパネルの動きが拘束されるため、耐震性能に優れるとは言い難い。そのため、最近はロッキング構法やスライド構法等の耐震性能のよい構法が多く採用されているが、上記従来の挿入筋構法で施工されたALC縦壁パネルを、そのまま使用し続けるのは好ましくない場合がある。   However, as described above, the vertical joints J1 of the ALC panels 4 and 4 that are horizontally adjacent to each other are filled with mortar and solidified so that the movement of the ALC panel is restricted in the event of an earthquake, etc. It is hard to say that it is excellent. Therefore, recently, many construction methods with good seismic performance such as rocking construction method and slide construction method have been adopted. However, it may not be desirable to continue using the ALC vertical wall panel constructed by the conventional insertion muscle construction method. is there.

またALCパネル1は経年劣化による母材の強度低下や、過去の地震などにより取付部耐力に支障を来すおそれもある。すなわち、経年劣化したALCパネルは一般に物性が低下し、それによって強度も低下する。しかし、経年劣化の程度は建物の維持管理、置かれている環境などによってまちまちで、今後の継続的な使用の適否をいつ判断すべきかは一概に決められないが、少なくとも20年以上経過したALC建物は専門化による劣化診断を受けて、適切なメンテナンスを行う必要がある。   In addition, the ALC panel 1 may have a problem in the strength of the mounting portion due to a decrease in the strength of the base material due to deterioration over time or a past earthquake. That is, the ALC panel that has deteriorated over time generally decreases in physical properties, thereby reducing the strength. However, the degree of deterioration over time varies depending on the maintenance of the building and the environment in which it is placed, and it is not possible to determine when it should be appropriate for continued use in the future. The building needs to undergo appropriate maintenance after receiving a specialized deterioration diagnosis.

その場合、かなり劣化を受けたALCパネルでも曲げ耐力は十分に安全側に設計されているので殆ど問題ないが、取付部強度については詳細な調査により、必要に応じて補強工事を行うとよく、また今後予想される大地震に対応するためにも、地球環境のためにも既存ALC建物の安全を考慮した補強対策が必要な場合も少なくない。しかし、既存建物はその殆どが使用中で、外壁の内部側には内装や屋内装置品等が設置されていることから、屋内側から補強対策を施すことはできない等の問題があった。   In that case, even if the ALC panel has undergone considerable deterioration, the bending strength is designed to be sufficiently safe, so there is almost no problem, but the strength of the mounting part should be reinforced as required by detailed investigation. In addition, in order to cope with a large earthquake that is expected in the future, there are many cases where reinforcement measures considering the safety of existing ALC buildings are necessary for the global environment. However, most of the existing buildings are in use, and interior parts and indoor equipment are installed on the inner side of the outer wall, so there is a problem that reinforcement measures cannot be taken from the indoor side.

特開平9−111929号公報Japanese Patent Laid-Open No. 9-11129

本発明は上記の問題点に鑑みて提案されたもので、既設のALC縦壁パネルを、その外部側からだけで容易に補強処理を行うことのできる既設ALC縦壁パネルの補強構造を提供することを目的とする。   The present invention has been proposed in view of the above problems, and provides a reinforcing structure for an existing ALC vertical wall panel that can easily reinforce an existing ALC vertical wall panel only from the outside. For the purpose.

上記の目的を達成するために本発明による既設ALC縦壁パネルの補強構造は、以下の構成としたものである。すなわち、建物躯体に下地鋼材を介して取付けた既設ALC縦壁パネルの補強構造であって、上記下地鋼材の側面にスタッド溶接等で固着したボルト等の棒状体を介して支持板を取付け、その支持板と上記下地鋼材との間に上記パネルを挟んで固定したことを特徴とする。   In order to achieve the above object, the reinforcing structure of the existing ALC vertical wall panel according to the present invention has the following configuration. That is, it is a reinforcing structure of an existing ALC vertical wall panel attached to a building frame via a base steel material, and a support plate is attached via a rod-like body such as a bolt fixed to the side surface of the base steel material by stud welding, etc. The panel is sandwiched and fixed between a support plate and the base steel material.

上記のように構成された本発明による既設ALC縦壁パネルの補強構造によれば、屋内が使用中であっても、また屋内に内装や屋内装置品があっても屋外側からだけの施工で下地鋼材に棒状体および支持板の取付が可能である。また上記下地鋼材の側面に棒状体を介して取付けた支持板と、上記下地鋼材との間に既設のパネルを挟み込むため、上記支持板の大きさや棒状体の設置本数等を適宜変更することで、上記支持板による支持面積や上記棒状体による取付強度等を任意に選択的に設定することが可能で、取付部分にかかる必要強度に応じた対応ができる。   According to the reinforcement structure of the existing ALC vertical wall panel according to the present invention configured as described above, even when indoors are in use, or even if there are interiors or indoor equipment items indoors, the construction can be performed only from the outdoor side. A rod-shaped body and a support plate can be attached to the base steel material. In addition, since the existing panel is sandwiched between the support plate attached to the side surface of the base steel material via a rod-like body and the base steel material, the size of the support plate, the number of rod-like bodies installed, etc. can be changed as appropriate. The support area by the support plate, the attachment strength by the rod-like body, and the like can be arbitrarily and selectively set, and it is possible to cope with the required strength applied to the attachment portion.

さらに、従来の目地鉄筋を切断する等、既設パネルの固定手段を開放する、或いは適当なスパン毎に垂直方向のエキスパンション目地を作成することで、固定構法をスライド構法に変身させることができる。また上記のような既存ALC縦壁パネルの取付部補強を行うことで、大地震に対するALCパネルの脱落防止や、欠け、亀裂などの被害の発生を最小限に食い止めることができるもので、既設建築物を安心して継続使用することが可能となる。   Furthermore, the fixed construction method can be transformed into a slide construction method by releasing the fixing means of the existing panel, such as by cutting a conventional joint reinforcement, or by creating a vertical expansion joint for each appropriate span. In addition, by reinforcing the mounting part of the existing ALC vertical wall panel as described above, it is possible to prevent the ALC panel from falling off due to a large earthquake and to prevent damage such as chipping and cracking. It becomes possible to continue to use things with peace of mind.

以下、図に示す実施形態に基づいて本発明を具体的に説明する。図1(a)は本発明による既設ALC縦壁パネルの補強構造の一実施形態を示す斜視図、同図(b)は(a)におけるb部の拡大図、同図(c)は要部の断面図である。   Hereinafter, the present invention will be specifically described based on the embodiments shown in the drawings. 1A is a perspective view showing an embodiment of a reinforcing structure of an existing ALC vertical wall panel according to the present invention, FIG. 1B is an enlarged view of a portion b in FIG. 1A, and FIG. FIG.

本実施形態は前記の挿入筋構法によって施工した既設ALC縦壁パネルに適用したもので、その既設ALC縦壁パネルは、前記従来例と同様に、建物躯体であるH形鋼等よりなる梁材1の上部にアングル材等よりなる下地鋼材2を取付け、その下地鋼材2の側面に溶接等で固着したタテカベプレート3にALCパネル4を載置すると共に、そのタテカベプレート3に形成した鉄筋挿通穴3a内および横方向に隣り合うALCパネル4・4間の縦目地J1内に目地鉄筋5を配設し、その目地鉄筋5の周囲の上記縦目地J1内にモルタル6等を充填して固化させた構成である。   The present embodiment is applied to an existing ALC vertical wall panel constructed by the above-mentioned insertion reinforcement construction method, and the existing ALC vertical wall panel is a beam material made of H-shaped steel or the like which is a building frame as in the conventional example. A base steel material 2 made of an angle material or the like is attached to the upper part of 1 and an ALC panel 4 is placed on a vertical plate 3 fixed to the side surface of the base steel material 2 by welding or the like, and a reinforcing bar formed on the vertical plate 3 A joint rebar 5 is arranged in the insertion hole 3a and in the vertical joint J1 between the ALC panels 4 and 4 adjacent in the horizontal direction, and the vertical joint J1 around the joint rebar 5 is filled with mortar 6 or the like. It is a solidified structure.

そして、本発明による補強構造は、上記下地鋼材2にスタッド溶接等で固着した棒状体7を介して支持板8を取付け、その支持板8と上記下地鋼材2との間に上記パネル4を挟んで固定したもので、図の場合は上記棒状体7としてボルトを下地鋼材2の側面にスタッド溶接等で固着し、そのボルトよりなる棒状体7にナット9をねじ込むことによって上記支持板8と下地鋼材2との間に上記パネル4を挟んだ状態で締め付け固定するようにしたものである。上記支持板8の表面には、図1に示すように必要に応じて装飾板やフィルムもしくは樹脂膜等の表装材10を被覆するようにしてもよく、図の場合は帯状の装飾板よりなる表装材10によって横目地J2をも含めて複数個の支持板8を帯状の表装材10で連続的に覆った構成である。   And the reinforcement structure by this invention attaches the support plate 8 via the rod-shaped body 7 fixed to the said base steel material 2 by stud welding etc., and sandwiches the said panel 4 between the support plate 8 and the said base steel material 2. FIG. In the case shown in the figure, a bolt is fixed to the side surface of the base steel material 2 by stud welding or the like as the rod-like body 7, and a nut 9 is screwed into the rod-like body 7 made of the bolt to thereby fix the support plate 8 and the base. The panel 4 is sandwiched between the steel material 2 and fastened and fixed. As shown in FIG. 1, the surface of the support plate 8 may be covered with a cover material 10 such as a decorative plate, a film, or a resin film as needed. A plurality of support plates 8 including the horizontal joint J <b> 2 are continuously covered with a band-shaped surface covering material 10 by the surface covering material 10.

上記補強構造を施工するに当たっては、例えば以下の要領で施工すればよい。即ち、先ず図2(a)に示すように下地鋼材2の側面に対応するパネル4の所定の位置に、図に省略したドリル等でパネル4の外面側からパネル厚さ方向に貫通する孔hを形成する。なお他の構法等で下地鋼材2の側面に対応する位置に横目地J2が無い場合には、下地鋼材2の側面に対応するパネル面に上記貫通孔hを形成するようにしてもよい。   In constructing the reinforcing structure, for example, construction may be performed in the following manner. That is, first, as shown in FIG. 2 (a), a hole h penetrating in the panel thickness direction from the outer surface side of the panel 4 at a predetermined position of the panel 4 corresponding to the side surface of the base steel material 2 with a drill or the like omitted in the drawing. Form. If there is no horizontal joint J2 at a position corresponding to the side surface of the base steel material 2 by another construction method or the like, the through hole h may be formed on the panel surface corresponding to the side surface of the base steel material 2.

次いで、図2(b)に示すようにパネル4の外面側から上記貫通孔h内に棒状体7を挿入してスタッド溶接等で該棒状体7を下地鋼材2の側面に固着すればよく、本実施形態においては上記棒状体7としてボルトを下地鋼材2の側面にスタッド溶接したもので、そのボルトよりなる棒状体7の下地鋼材2と反対側の端部7aには、予め雄ねじが形成されている。そして、上記棒状体7の端部7aを図2(c)に示すように支持板8に形成した穴(不図示)に挿通し、上記端部7aにナット9をねじ込めば、上記支持板8と下地鋼材2との間に上記パネル4を挟んだ状態で締め付け固定することができる。   Next, as shown in FIG. 2 (b), the rod-like body 7 is inserted into the through hole h from the outer surface side of the panel 4 and the rod-like body 7 is fixed to the side surface of the base steel material 2 by stud welding or the like. In the present embodiment, a bolt is stud-welded to the side surface of the base steel material 2 as the rod-shaped body 7, and a male screw is formed in advance on the end 7 a opposite to the base steel material 2 of the rod-shaped body 7 made of the bolt. ing. Then, the end 7a of the rod 7 is inserted into a hole (not shown) formed in the support plate 8 as shown in FIG. 2 (c), and a nut 9 is screwed into the end 7a. The panel 4 can be clamped and fixed between the steel 8 and the base steel material 2.

次に、上記支持板8の表面に表装材10を被覆する場合には、その表装材10を例えば図2(d)のように支持板8よりも幅広で支持板8がはまり込む様形成しておき、支持板8をはめ込んで固着するか、表装材10の両側縁部をパネル表面にアルミカットネイル等で固着する。或いは前記のナットを利用して上記表装材10を固定するようにしてもよいが、上記ナット9および棒状体7の端部7a並びに横目地J2をも含めて表装材10で覆うようにすると外観体裁よく構成することができる。   Next, when covering the surface of the support plate 8 with the surface material 10, the surface material 10 is formed wider than the support plate 8, for example, as shown in FIG. The support plate 8 is fitted and fixed, or both side edges of the cover material 10 are fixed to the panel surface with an aluminum cut nail or the like. Or you may make it fix the said cover material 10 using the said nut, but when it is made to cover with the cover material 10 including the said nut 9, the edge part 7a of the rod-shaped body 7, and the horizontal joint J2, it is an external appearance. It can be structured nicely.

上記のようにして支持板8と下地鋼材2との間にパネル4を挟んで固定することによって、既設のALC縦壁パネルを簡単・確実に補強することができるもので、その際の施工は上記のようにパネルの外側、すなわち屋外側からだけでできるので、屋内が使用中であっても、また屋内に内装や屋内装置品があっても何ら支障がない。また上記支持板8の大きさや棒状体7の設置本数等を適宜変更することで、上記支持板8による支持面積や上記棒状体7による取付強度等を任意に選択的に設定することが可能で、耐震強度等の必要強度を容易に確保することができる。   By fixing the panel 4 between the support plate 8 and the base steel material 2 as described above, the existing ALC vertical wall panel can be easily and reliably reinforced. As described above, since it can be performed only from the outside of the panel, that is, from the outdoor side, there is no problem even if the interior is in use, or if there are interiors or indoor equipment items inside. In addition, by appropriately changing the size of the support plate 8 and the number of the rod-like bodies 7 installed, the support area by the support plate 8 and the mounting strength by the rod-like body 7 can be arbitrarily and selectively set. The required strength such as seismic strength can be easily secured.

さらに、上記実施形態のように挿入筋構法によって施工した既設ALC縦壁パネルにあっては前記の目地鉄筋5を適宜の位置、例えば図3に示すようにタテカベプレート3と、その下側のパネル4との間に図中矢印の方向からカッタ等を挿入して切断する等して既設パネルの固定状態を適宜開放する、更に図4のように縦目地J1内の一部にエキスパンション目地11等を作成して、各パネル4を、その面内方向に移動可能に構成すれば、例えば地震等の際に前記従来のパネル4は移動不能であったものが、本発明においては図4(a)、(b)のように各パネル4がスライド移動もしくは傾動して衝撃等を緩和することができる。それによって、前記従来の挿入筋構法のような固定構法をスライド構法等の耐震性や耐久性のよい構法もしくは構造に変身させることができる。また上記のような既存ALC縦壁パネルの取付部補強を行うことで、大地震に対するALCパネルの脱落防止や、欠け、亀裂などの被害の発生を最小限に食い止めることが可能となり、既設建築物を安心して継続使用することが可能となるものである。   Furthermore, in the existing ALC vertical wall panel constructed by the insertion bar construction method as in the above embodiment, the joint reinforcing bar 5 is placed at an appropriate position, for example, the vertical plate 3 as shown in FIG. The fixing state of the existing panel is released as appropriate by inserting a cutter or the like from the direction of the arrow in the figure and cutting it between the panel 4 and the expansion joint 11 in a part of the vertical joint J1 as shown in FIG. Etc., and each panel 4 is configured to be movable in the in-plane direction. For example, in the present invention, the conventional panel 4 cannot be moved during an earthquake or the like. As shown in a) and (b), each panel 4 can be slid or moved to reduce the impact. Accordingly, the fixed construction method such as the conventional insertion muscle construction method can be transformed into a construction method or structure having good earthquake resistance and durability such as a slide construction method. In addition, by reinforcing the mounting part of the existing ALC vertical wall panel as described above, it becomes possible to prevent the ALC panel from falling off due to a large earthquake and to prevent damage such as chipping and cracking. Can be used continuously with peace of mind.

上記実施形態は、支持板8として短冊状のものを用いたが、長尺帯状のものを用いてもよい。図5はその一例を示すもので、同図(a)は本発明による既設ALC縦壁パネルの補強構造の他の実施形態を示す斜視図、同図(b)は(a)におけるb部の拡大図、同図(c)は要部の断面図である。   Although the said embodiment used the strip-shaped thing as the support plate 8, you may use a long strip | belt-shaped thing. FIG. 5 shows an example thereof. FIG. 5 (a) is a perspective view showing another embodiment of the reinforcing structure of the existing ALC vertical wall panel according to the present invention, and FIG. 5 (b) is a view of part b in FIG. An enlarged view and the same figure (c) are sectional views of the principal part.

本実施形態は、挿入筋構法によって施工した既設ALC縦壁パネル4の横目地J2に沿って長尺帯状の支持板8を配置し、その支持板8に、前記実施系形態と同様に下地鋼材2にスタッド溶接等で固着したボルト等よりなる棒状体7の他端を挿通すると共に、その棒状体7の先端部にねじ込んだナット9によって、上記支持板8と上記下地鋼材2との間に上記パネル4を挟んで締め付け固定したものである。上記棒状体7とナット9とは、それぞれ上下に配設したパネル4・4間のパネル幅方向中央部に1つずつ設けられている。他の構成は前記図1の実施形態と同様である。   In the present embodiment, a long strip-shaped support plate 8 is disposed along the horizontal joint J2 of the existing ALC vertical wall panel 4 constructed by the insertion muscle construction method, and the base steel material is provided on the support plate 8 in the same manner as in the above-described embodiment. 2 is inserted between the support plate 8 and the base steel material 2 by a nut 9 screwed into the tip of the rod-like body 7. The panel 4 is clamped and fixed. The rod-like body 7 and the nut 9 are provided one by one in the center portion in the panel width direction between the panels 4 and 4 arranged vertically. Other configurations are the same as those of the embodiment of FIG.

上記の補強構造を施工するに当たっては、前記実施形態とほぼ同様の要領で施工すればよく、先ず図6(a)に示すように下地鋼材2の側面に対応するパネル4の所定の位置に、図に省略したドリル等でパネル4の外面側からパネル厚さ方向に貫通する孔hを形成する。次いで、図6(b)に示すようにパネル4の外面側から上記貫通孔h内に棒状体7を挿入してスタッド溶接等で該棒状体7を下地鋼材2の側面に固着し、その棒状体7の端部7aを同図(c)に示すように支持板8に形成した穴(不図示)に挿通すると共に、上記棒状体7の端部7aに形成した雄ねじにナット9をねじ込むことによって、上記支持板8と下地鋼材2との間に上記パネル4を挟んだ状態で締め付け固定する。   In constructing the above reinforcing structure, it may be constructed in substantially the same manner as in the above embodiment, and first, at a predetermined position of the panel 4 corresponding to the side surface of the base steel material 2 as shown in FIG. A hole h penetrating in the panel thickness direction from the outer surface side of the panel 4 is formed by a drill or the like omitted in the drawing. Next, as shown in FIG. 6B, the rod-like body 7 is inserted into the through hole h from the outer surface side of the panel 4, and the rod-like body 7 is fixed to the side surface of the base steel material 2 by stud welding or the like. The end 7a of the body 7 is inserted into a hole (not shown) formed in the support plate 8 as shown in FIG. 3C, and the nut 9 is screwed into the male screw formed in the end 7a of the rod-like body 7. Thus, the panel 4 is clamped and fixed between the support plate 8 and the base steel material 2.

次いで、上記支持板8の表面には、必要に応じて装飾板やフィルムもしくは樹脂膜等の表装材10を被覆するもので、その場合には上記表装材10を図6(d)のように支持板8を覆うように配置して、その表装材10を前記実施形態と同様の要領でパネル表面等に固着もしくは固定すればよい。   Next, the surface of the support plate 8 is covered with a surface covering material 10 such as a decorative plate, a film, or a resin film as necessary. In this case, the surface covering material 10 is coated as shown in FIG. What is necessary is just to arrange | position so that the support plate 8 may be covered, and to fix or fix the surface covering material 10 to the panel surface etc. in the same way as the said embodiment.

上記図5および図6の実施形態においても前記図1および図2の実施形態と同様の作用効果が得られる。なお、上記各実施形態は、棒状体7としてボルトを用いたが、例えばアンカースリーブ等の筒状のものを用い、その内周面に形成した雌ねじにボルト等をねじ込んで上記支持板8を締め付け固定するようにしてもよい。   Also in the embodiment of FIGS. 5 and 6, the same effect as that of the embodiment of FIGS. 1 and 2 can be obtained. In each of the above embodiments, a bolt is used as the rod-like body 7. However, for example, a cylindrical member such as an anchor sleeve is used, and the support plate 8 is tightened by screwing the bolt into a female screw formed on the inner peripheral surface thereof. It may be fixed.

以上のように本発明によれば、既設のALC縦壁パネルを建築物の外側から簡単・確実に補強することができるので、例えば前記従来の挿入筋構法のようなALC縦壁パネルの耐震性能や耐久性もしくはパネル取付強度が必ずしも充分ではない既設の建築物であって現在使用中のものでも居住者や使用者に何ら負担を掛けることなく施工可能であり、既設建築物におけるALC縦壁パネルの補強構造として産業上も極めて有効かつ適切に利用することができる。   As described above, according to the present invention, the existing ALC vertical wall panel can be easily and reliably reinforced from the outside of the building. For example, the seismic performance of the ALC vertical wall panel as in the conventional insertion muscle construction method is used. ALC vertical wall panels in existing buildings that can be constructed without any burden on residents and users even if they are existing buildings that are not necessarily durable or have sufficient panel mounting strength. As a reinforcing structure, it can be used extremely effectively and appropriately in industry.
