Description

本発明は建物の内装工事に関連し、特に鉄筋コンクリート壁等の高剛性の壁面に対してドア枠や窓枠等の建具枠を設置するための構造に関する。   The present invention relates to building interior construction, and more particularly to a structure for installing a joinery frame such as a door frame or a window frame on a highly rigid wall surface such as a reinforced concrete wall.

周知のように、鉄筋コンクリート造の建物の施工に際して壁面にドアや窓等の開口部を設ける場合には、壁面を施工する際に予め開口部を設けてその内側にドア枠や窓枠等の建具枠を後付けしたうえでそこに扉や窓ガラスを建て込むことが一般的であり、そのような場合において建具枠を開口部の内側に固定するための作業を精度良く効率的に行うためにたとえば特許文献１に示される工法も提案されている。   As is well known, when installing openings such as doors and windows on the wall surface when constructing reinforced concrete buildings, an opening is provided in advance when constructing the wall surface, and fittings such as door frames and window frames inside It is common to install a door or window glass after retrofitting the frame. In such a case, in order to perform the work for fixing the joinery frame inside the opening accurately and efficiently, for example, A construction method disclosed in Patent Document 1 has also been proposed.

特開２００１−１６４８３４号公報JP 2001-164834 A

ところで、鉄筋コンクリート造（ＰＣａ造を含む）の建物においては地震時の層間変形を考慮して壁面を床面に対して水平方向に相対変位可能（すなわちスウェイ可能）に接合する場合があるが、その場合には壁面に固定した建具枠が地震時に損傷を受けてしまうことがある。   By the way, in a reinforced concrete structure (including PCa structure), the wall surface may be joined to the floor surface in a horizontal direction so that it can be displaced relative to the floor surface in consideration of the interlayer deformation at the time of earthquake. In some cases, the joinery frame fixed to the wall surface may be damaged during an earthquake.

すなわち、たとえば図２（ａ）に示すように、鉄筋コンクリート造の壁面１（ＰＣａ版を含む）を床面２に対して水平スリット３を介して水平方向に相対変位（スウェイ）可能に設置する場合において、その壁面１に掃き出し窓を設ける場合には、壁面１の施工の際に窓枠４よりも大きい開口部５を予め設けたうえでその内側に窓枠４を配置し、窓枠４の周囲全体にモルタル６等の硬化性充填材を充填することによって窓枠４を開口部５の内側に固定することが一般的である。   That is, for example, as shown in FIG. 2 (a), a reinforced concrete wall 1 (including a PCa plate) is installed so as to be capable of relative displacement (sway) in the horizontal direction with respect to the floor 2 via a horizontal slit 3. In order to provide a sweeping window on the wall surface 1, an opening 5 larger than the window frame 4 is provided in advance when the wall surface 1 is constructed, and then the window frame 4 is disposed inside the window frame 4. In general, the window frame 4 is fixed inside the opening 5 by filling the entire periphery with a curable filler such as mortar 6.

その場合、地震時に（ｂ）に示すように層間変形が生じて壁面１全体が床面２に対して水平方向に相対変位すると、壁面１に対して固定されている窓枠４も壁面１ととともに水平変位しようとするが、窓枠４の底部は床面２に対して固定されているのでそこでの水平変位は拘束されてしまい、したがって窓枠４全体が平行四辺形となるように変形して特にその脚部（図中に×印で示す部位）に無理な応力が生じてしまい、その結果、窓枠４の底部が座屈したり、開口部５との間に充填されているモルタル６が剥落したり、さらには壁面１の下部が損傷してしまう等の事故が生じる場合がある。   In that case, when an interlayer deformation occurs as shown in (b) during the earthquake and the entire wall surface 1 is displaced relative to the floor surface 2 in the horizontal direction, the window frame 4 fixed to the wall surface 1 is also At the same time, the bottom of the window frame 4 is fixed with respect to the floor 2, so that the horizontal displacement is constrained, so that the entire window frame 4 is deformed to become a parallelogram. In particular, an excessive stress is generated in the leg portion (portion indicated by an X in the figure). As a result, the bottom portion of the window frame 4 is buckled or the mortar 6 filled between the opening portion 5 is filled. May come off, or may cause an accident such as damage to the lower portion of the wall 1.

そして、そのような損傷が生じると窓枠４の交換やモルタル６さらには壁面１の補修が必要となって多大の手間と費用を必要とするので、かねてよりそのような事態を防止し得る有効適切な手段の開発が望まれていた。   When such damage occurs, replacement of the window frame 4 and repair of the mortar 6 and further the wall surface 1 are necessary, which requires a great deal of labor and cost, so that it is possible to prevent such a situation for some time. The development of appropriate means was desired.

上記事情に鑑み、請求項１記載の発明は、図１に示すように床面２に対して水平スリット３を介して水平方向に相対変位可能に接合された高剛性の壁面１に開口部５を設け、該開口部５の内側に建具枠（図１では窓枠４）を配置して該建具枠の底部を前記床面２に対して水平変位不能に固定するとともに、該建具枠の両側部および上部の三方向の周囲と前記開口部５との間に確保したクリアランス内にモルタル６等の硬化性充填材を充填して前記建具枠を前記壁面１に対して固定するようにした壁面への建具枠の設置構造であって、前記建具枠の少なくとも両側部の脚部と前記開口部５との間には、それら建具枠と壁面１との間の水平方向の相対変位を許容可能な柔軟な緩衝材７を前記硬化性充填材に代えて充填してなることを特徴とする。   In view of the above circumstances, the invention according to claim 1 has an opening 5 in a highly rigid wall surface 1 joined to a floor surface 2 through a horizontal slit 3 so as to be relatively displaceable in the horizontal direction as shown in FIG. 1 is disposed inside the opening 5 to fix the bottom of the joinery frame to the floor 2 so as not to be horizontally displaceable, and on both sides of the joinery frame. A wall surface that is fixed to the wall surface 1 by filling a curable filler such as a mortar 6 in a clearance secured between the periphery in the three directions of the upper part and the upper part and the opening 5. The installation structure of the joinery frame to the horizontal frame between the joinery frame and the wall surface 1 can be allowed between at least the legs of the joinery frame and the opening 5. A flexible buffer material 7 is filled instead of the curable filler.

請求項２記載の発明は、請求項１記載の壁面への建具枠の設置構造であって、前記緩衝材７はロックウールであることを特徴とする。   Invention of Claim 2 is the installation structure of the joinery frame to the wall surface of Claim 1, Comprising: The said buffer material 7 is rock wool, It is characterized by the above-mentioned.

本発明によれば、建具枠の底部は床面２に対して固定され、建具枠の上部は壁面１に対して固定されるが、少なくとも建具枠の両側部の下部と壁面１との間は柔軟な緩衝材７により塞がれるのみとなり、したがって地震時に壁面１が床面２に対して水平方向に相対変位を生じた際にはそれに追随して緩衝材７が自由に変形してそこでの相対変形を支障なく吸収し得るものとなり、以て、従来のようにそこに大きな応力が生じて建具枠が座屈したり、そこに充填されていたモルタル６等の硬化性充填材やさらには壁面１下部が損傷してしまうようなことを未然に防止することが可能である。   According to the present invention, the bottom part of the joinery frame is fixed to the floor surface 2 and the upper part of the joinery frame is fixed to the wall surface 1, but at least between the lower part of the both sides of the joinery frame and the wall surface 1. Therefore, when the wall 1 is displaced relative to the floor 2 in the horizontal direction at the time of an earthquake, the shock absorber 7 is freely deformed to follow the displacement. Relative deformation can be absorbed without hindrance, and as a result, a large stress is generated there as in conventional cases, the joinery frame buckles, and curable fillers such as mortar 6 and the wall surface filled therewith 1 It is possible to prevent the lower part from being damaged.

本発明の壁面への建具枠の設置構造の実施形態を示す図である。It is a figure which shows embodiment of the installation structure of the joinery frame to the wall surface of this invention. 従来一般の壁面への建具枠の設置構造を示す図である。It is a figure which shows the installation structure of the joinery frame to the conventional general wall surface.

図１に本発明の実施形態を示す。
これは、図２に示したように鉄筋コンクリート造の建物において床面２に対して水平スリット３を介してスウェイ可能に接合された壁面１に対して掃き出し窓を設置する場合の適用例であって、基本的には図２の場合と同様に壁面１に掃き出し窓用の窓枠４よりも大きい開口部５を設けてその内側に窓枠４を配置し、それら窓枠４と開口部５との間に確保したクリアランス内にモルタル６等の硬化性充填材を充填することによって窓枠４を固定するようにしたものであるが、本実施形態の設置構造が従来の設置構造と異なる点は、従来においては窓枠４の全周にわたってモルタル６を均等に充填していたのに対し、本実施形態では窓枠４の両側部の脚部と開口部５との間（図１（ａ）で鎖線で囲んで示した範囲）にはモルタル６を充填することに代えて柔軟な緩衝材７を充填したことを主眼とする。 FIG. 1 shows an embodiment of the present invention.
This is an application example in the case where a sweep window is installed on a wall surface 1 joined to a floor surface 2 through a horizontal slit 3 in a reinforced concrete building as shown in FIG. Basically, as in the case of FIG. 2, an opening 5 larger than the window frame 4 for the sweep window is provided on the wall surface 1, and the window frame 4 is disposed on the inside thereof, and the window frame 4, the opening 5, The window frame 4 is fixed by filling a curable filler such as mortar 6 in the clearance secured between the two, but the difference between the installation structure of this embodiment and the conventional installation structure is that In the prior art, the mortar 6 is uniformly filled over the entire circumference of the window frame 4, whereas in the present embodiment, the gap between the leg portions on both sides of the window frame 4 and the opening 5 (FIG. 1A). Mortar 6 is filled in the area surrounded by the chain line. And it focuses on filled with flexible cushioning material 7 in place.

その緩衝材７としては、モルタル６と同様にクリアランスを塞ぐ機能を有するものであることに加えて、（ｂ）に示すように壁面１が床面２に対して水平方向に相対変位（スウェイ）を生じた際には自由に変形して窓枠４に対する壁面１の相対変位を拘束することなく許容し、かつ、その際に緩衝材７自体が損傷を受けてしまうことのない程度の柔軟性を有する材料であることが必要であり、その限りにおいて各種の弾性材料や塑性材料が採用可能であるが、特にモルタル６と同様に安価に入手可能であり、現場での取り扱いが容易で施工性に優れ、しかも耐火性能を有する建設資材であるロックウールが好適に採用可能である。   As the buffer material 7, in addition to having a function of closing the clearance in the same manner as the mortar 6, the wall surface 1 is relatively displaced (sway) in the horizontal direction with respect to the floor surface 2 as shown in FIG. When this occurs, it is freely deformed to allow the relative displacement of the wall surface 1 with respect to the window frame 4 without being constrained, and at the same time, the cushioning material 7 itself is not damaged. It is necessary to use various elastic materials and plastic materials as long as the material is used. However, as with the mortar 6, it can be obtained at a low price, and is easy to handle on site and easy to work. Rock wool, which is a construction material having excellent fire resistance and fire resistance, can be suitably used.

上記の構造によれば、従来と同等に窓枠４の底部はモルタル６を介して床面２に対して固定され、窓枠４の上部も同じくモルタル６を介して壁面１に対して固定されるが、窓枠４の両側部の下部と壁面１との間の隙間は柔軟な緩衝材７により塞がれるのみとなり、したがって地震時に壁面１がスウェイを生じた際にはそれに追随して緩衝材７が自由に変形し、以て、従来のようにそこに大きな応力が生じて窓枠４が座屈したり、従来においてはそこに充填されているモルタル６やさらには壁面１下部が損傷してしまうことを未然に防止することが可能である。   According to said structure, the bottom part of the window frame 4 is fixed with respect to the floor surface 2 via the mortar 6, and the upper part of the window frame 4 is also fixed with respect to the wall surface 1 via the mortar 6 similarly to the past. However, the gap between the lower part of the both side portions of the window frame 4 and the wall surface 1 is only blocked by the flexible cushioning material 7, so that when the wall surface 1 is swayed during an earthquake, it follows and cushions it. The material 7 is freely deformed, so that a large stress is generated there as in the conventional case, the window frame 4 is buckled, and the mortar 6 and further the lower part of the wall surface 1 are damaged in the conventional case. It is possible to prevent this from happening.

なお、緩衝材７の充填位置は、上記実施形態のように少なくとも変形が顕著に生じる窓枠４の両側部の下部の位置に限定することが現実的であり、通常はそれで十分であるが、必要であればモルタル６（あるいはそれに代わる適宜の硬化性充填材）による窓枠４全体に対する固定強度が損なわれることがない範囲で、より広範囲にわたって緩衝材７を充填することでも良い。
また、クリアランスの寸法（開口部５と窓枠４との間の隙間の大きさ）は従来と同等程度で良いが、少なくともスウェイ時に想定される水平方向の最大相対変位以上としておくことが好ましく、それにより最大相対変位が生じて緩衝材７が最大限に変形した場合においても壁面１が窓枠４に衝突することを確実に防止することができる。 In addition, it is realistic to limit the filling position of the cushioning material 7 to the position of the lower part of the both sides of the window frame 4 where deformation is remarkable as in the above-described embodiment, which is usually sufficient, If necessary, the buffer material 7 may be filled over a wider range as long as the fixing strength of the entire window frame 4 by the mortar 6 (or an appropriate curable filler instead of the mortar 6) is not impaired.
In addition, the clearance dimension (the size of the gap between the opening 5 and the window frame 4) may be about the same as the conventional one, but it is preferable to set at least the horizontal maximum relative displacement assumed at the time of the sway, Thereby, even when the maximum relative displacement occurs and the cushioning material 7 is deformed to the maximum extent, the wall surface 1 can be reliably prevented from colliding with the window frame 4.

さらに、上記実施形態は鉄筋コンクリート造（ＰＣａ造を含む）の壁面１に対して掃き出し窓用の窓枠４を設置する場合の適用例であるが、本発明は上記実施形態に限定されるものでは勿論なく、各種構造の壁面に対して各種用途の建具枠を同様の条件で設置する場合全般に広く適用できることは当然である。   Furthermore, although the said embodiment is an application example in the case of installing the window frame 4 for sweeping windows with respect to the wall surface 1 of a reinforced concrete structure (a PCa structure is included), this invention is not limited to the said embodiment. Of course, it is natural that the present invention can be widely applied to the case where the frame for various uses is installed on the wall surface of various structures under the same conditions.
