Description

本発明は、建築物の開口縁部に設置される枠体と、枠体を備えた建具に関する。   The present invention relates to a frame body installed at an opening edge portion of a building and a fitting including the frame body.

金属と樹脂の複合構造の枠体は、各種の建具（窓、ドア等）の開口枠として用いられている。枠体の金属枠は、建築物の開口縁部に配置されて、例えば、開口縁部の額縁内で露出する。この場合には、冬季等に、金属枠の室内側部の表面温度が低下して、金属枠の室内側部に結露が発生することがある。これに対し、従来、アルミ下枠（金属枠）の室内側部を樹脂補助枠（樹脂カバー）で覆い、アルミ下枠の室内側部の露出を防止する窓枠が知られている（特許文献１参照）。   A frame body having a composite structure of metal and resin is used as an opening frame of various fittings (windows, doors, etc.). The metal frame of the frame body is arranged at the opening edge portion of the building and is exposed in the frame of the opening edge portion, for example. In this case, in winter or the like, the surface temperature of the inner side portion of the metal frame may decrease, and dew condensation may occur on the inner side portion of the metal frame. On the other hand, conventionally, there is known a window frame in which the inner side portion of the aluminum lower frame (metal frame) is covered with a resin auxiliary frame (resin cover) to prevent the inner side portion of the aluminum lower frame from being exposed (Patent Document 1). 1).

ところが、特許文献１に記載された従来の窓枠では、樹脂補助枠とアルミ下枠の室内側部との接触面積が大きくなる。その結果、樹脂補助枠とアルミ下枠の室内側部との間で熱が伝導し易く、室内側における窓枠の断熱性に影響が生じる虞がある。また、樹脂補助枠の表面温度が低下して、樹脂補助枠に結露が発生する虞もある。   However, in the conventional window frame described in Patent Document 1, the contact area between the resin auxiliary frame and the inner side portion of the aluminum lower frame is large. As a result, heat is likely to be conducted between the resin auxiliary frame and the indoor side portion of the aluminum lower frame, which may affect the heat insulating property of the window frame on the indoor side. Further, the surface temperature of the resin auxiliary frame may decrease, and dew condensation may occur on the resin auxiliary frame.

下枠５と同様に、上枠６（図４参照）において、空所５５が第２上樹脂カバー５０の中空部５１と上金属枠６Ａの室内側部６Ｄの間に形成され、第２上樹脂カバー５０が突出部５２のみで上金属枠６Ａに接触する。また、縦枠７（図５参照）において、空所７５が第２縦樹脂カバー７０の中空部７１と縦金属枠７Ａの室内側部７Ｃの間に形成され、第２縦樹脂カバー７０が突出部７２のみで縦金属枠７Ａに接触する。そのため、上枠６と縦枠７においても、各樹脂カバー５０、７０の表面温度の低下を抑制して、各樹脂カバー５０、７０での結露の発生を抑制でき、断熱性と防露性能を向上させることができる。   Similar to the lower frame 5, in the upper frame 6 (see FIG. 4), the void 55 is formed between the hollow portion 51 of the second upper resin cover 50 and the indoor side portion 6D of the upper metal frame 6A, and the second upper portion is formed. The resin cover 50 contacts the upper metal frame 6A only by the protruding portion 52. Further, in the vertical frame 7 (see FIG. 5), a void 75 is formed between the hollow portion 71 of the second vertical resin cover 70 and the indoor side portion 7C of the vertical metal frame 7A, and the second vertical resin cover 70 projects. Only the portion 72 contacts the vertical metal frame 7A. Therefore, also in the upper frame 6 and the vertical frame 7, it is possible to suppress the decrease in the surface temperature of the resin covers 50 and 70, and to suppress the occurrence of dew condensation on the resin covers 50 and 70, thereby improving the heat insulation property and the dew-proof performance. Can be improved.

下枠５（図３参照）では、中空部３１において内部空間３１Ａ、３１Ｂを区画する室外側の壁部（接続部３１Ｃの上下に位置する壁部）と、区画壁３２により、接続部３１Ｃの剛性が向上するため、接続部３１Ｃから突出する突出部３６も変形し難い。また、取付部３４により、第３下樹脂カバー３０を建築物の開口縁部に直接取り付けて、開口縁部に第３下樹脂カバー３０を確実に保持することができる。下枠５に荷重がかかると、下方向の力が下金属枠５Ａに加えられる。その際、一対の係合部５Ｉ、５Ｊが一対の突出部３５、３６により拘束されるため、下金属枠５Ａが第３下樹脂カバー３０に対して回転変位するのを抑制することができる。より具体的には、図３において、下枠５の上面に荷重がかかることで、下枠５に反時計回り（下枠５の室外側寄りが下方に、下枠５の室内側寄りが上方にそれぞれ向かう方向の回転）の回転力が作用する。この場合に、ネジＳ７を用いて開口縁部に固着された取付部３４を有する第３下樹脂カバー３０の突出部３６によって、下金属枠５Ａの係合部５Ｊの上方への移動が規制される。これにより、下枠５の回転変位を抑制することができる。   In the lower frame 5 (see FIG. 3 ), the wall portion on the outdoor side (the wall portions located above and below the connection portion 31C) that divides the internal spaces 31A and 31B in the hollow portion 31 and the partition wall 32 form the connection portion 31C. Since the rigidity is improved, the protruding portion 36 protruding from the connecting portion 31C is also unlikely to be deformed. In addition, the attachment portion 34 allows the third lower resin cover 30 to be directly attached to the opening edge portion of the building, and the third lower resin cover 30 can be reliably held at the opening edge portion. When a load is applied to the lower frame 5, a downward force is applied to the lower metal frame 5A. At this time, since the pair of engaging portions 5I and 5J are constrained by the pair of projecting portions 35 and 36, it is possible to suppress rotational displacement of the lower metal frame 5A with respect to the third lower resin cover 30. More specifically, in FIG. 3, a load is applied to the upper surface of the lower frame 5 so that the lower frame 5 rotates counterclockwise (the lower frame 5 is located closer to the outdoor side and the lower frame 5 is located closer to the indoor side. The rotation force acts in the direction of the rotation. In this case, the upward movement of the engaging portion 5J of the lower metal frame 5A is restricted by the protrusion 36 of the third lower resin cover 30 having the mounting portion 34 fixed to the opening edge portion with the screw S7. It Thereby, the rotational displacement of the lower frame 5 can be suppressed.

なお、第３下樹脂カバー３０の区画壁３２と同様の区画壁を、第２上樹脂カバー５０と第２縦樹脂カバー７０に設けてもよく、第３下樹脂カバー３０の取付部３４と同様の取付部を、第２上樹脂カバー５０と第２縦樹脂カバー７０に設けてもよい。また、下金属枠５Ａの室内側部５Ｄと係合する第３下樹脂カバー３０の一対の突出部３５、３６と同様に、一対の突出部を第２上樹脂カバー５０に設けて室内側部６Ｄの一対の係合部に係合させてもよく、一対の突出部を第２縦樹脂カバー７０に設けて室内側部７Ｃの一対の係合部に係合させてもよい。室内側部５Ｄ、６Ｄ、７Ｃを覆う樹脂カバー３０、５０、７０には、各枠５〜７の構造に対応して、少なくとも１つの突出部が設けられる。即ち、１つの突出部が樹脂カバー３０、５０、７０に設けられ、或いは、複数の突出部が樹脂カバー３０、５０、７０に設けられる。   A partition wall similar to the partition wall 32 of the third lower resin cover 30 may be provided in the second upper resin cover 50 and the second vertical resin cover 70, and similar to the mounting portion 34 of the third lower resin cover 30. The mounting portion of may be provided on the second upper resin cover 50 and the second vertical resin cover 70. In addition, as with the pair of protrusions 35 and 36 of the third lower resin cover 30 that engages with the inner side portion 5D of the lower metal frame 5A, a pair of protrusions is provided on the second upper resin cover 50 to form the inner side portion. The pair of engaging portions of 6D may be engaged, or the pair of protruding portions may be provided on the second vertical resin cover 70 to engage with the pair of engaging portions of the indoor side portion 7C. At least one projecting portion is provided on the resin covers 30, 50, 70 that cover the indoor side portions 5D, 6D, 7C, corresponding to the structure of each frame 5-7. That is, one protrusion is provided on the resin covers 30, 50, 70, or a plurality of protrusions is provided on the resin covers 30, 50, 70.

（第２実施形態）
第２実施形態の建具１では、下枠５の第３下樹脂カバー３０のみが、第１実施形態の第３下樹脂カバー３０と相違する。そのため、第２実施形態では、第３下樹脂カバー３０のみについて説明する。第２実施形態の建具１に関して、第１実施形態の建具１が備える構成に相当する構成には、第１実施形態の建具１の構成と同じ名称と符号を用いる。また、以下では、既に説明した事項と相違する事項を説明し、既に説明した事項と同じ事項の説明は省略する。 (Second embodiment)
In the fitting 1 of the second embodiment, only the third lower resin cover 30 of the lower frame 5 is different from the third lower resin cover 30 of the first embodiment. Therefore, in the second embodiment, only the third lower resin cover 30 will be described. Regarding the fitting 1 of the second embodiment, the same names and reference numerals as those of the fitting 1 of the first embodiment are used for the configuration corresponding to the configuration of the fitting 1 of the first embodiment. Further, hereinafter, items different from the items already described will be described, and description of the same items as the already described items will be omitted.

図６は、第２実施形態の建具１の下枠５を示す断面図であり、下枠５を図３と同様に示している。
図示のように、第３下樹脂カバー３０は、中空部３１に替えて、下金属枠５Ａの室内側部５Ｄに対して見込み方向で対向する対向部３９を有する。また、第３下樹脂カバー３０は、突起３３と、取付部３４と、複数の突出部３５〜３７を有する。対向部３９は、室内側部５Ｄの見込み方向室内側を覆う板状のカバー部であり、第３下樹脂カバー３０の長手方向に連続して設けられている。室内側部５Ｄの室内側において、対向部３９が下枠５の見付け方向に沿って形成されて、対向部３９により、室内側部５Ｄの見込み方向室内側の全体が覆われる。 FIG. 6 is a cross-sectional view showing the lower frame 5 of the fitting 1 of the second embodiment, and shows the lower frame 5 as in FIG.
As illustrated, the third lower resin cover 30 has a facing portion 39 that faces the indoor side portion 5D of the lower metal frame 5A in the prospective direction, instead of the hollow portion 31. The third lower resin cover 30 also has a protrusion 33, a mounting portion 34, and a plurality of protruding portions 35 to 37. The facing portion 39 is a plate-shaped cover portion that covers the indoor side of the indoor side portion 5D in the prospective direction, and is provided continuously in the longitudinal direction of the third lower resin cover 30. On the indoor side of the indoor side portion 5D, the facing portion 39 is formed along the finding direction of the lower frame 5, and the facing portion 39 covers the entire indoor side portion 5D in the prospective direction indoor side.

突起３３は、対向部３９に形成される。対向部３９と突片１３の間に位置する突起３３により、隙間１９が第３下樹脂カバー３０と突片１３の間に形成される。取付部３４は、対向部３９から室内側に突出する。突出部３５〜３７は、対向部３９から下金属枠５Ａの室内側部５Ｄに向かって見込み方向室外側に突出して、対向部３９と室内側部５Ｄの間に空所３８Ａ、３８Ｂを形成する。   The protrusion 33 is formed on the facing portion 39. The gap 33 is formed between the third lower resin cover 30 and the protrusion 13 by the protrusion 33 located between the facing portion 39 and the protrusion 13. The mounting portion 34 projects from the facing portion 39 toward the indoor side. The projecting portions 35 to 37 project outward from the facing portion 39 toward the indoor side portion 5D of the lower metal frame 5A in the prospective direction and form cavities 38A and 38B between the facing portion 39 and the indoor side portion 5D. ..

対向部３９は、下金属枠５Ａに接触せず、突出部３５〜３７は、対向部３９から室内側部５Ｄまで突出する。突出部３５〜３７により、対向部３９は、室内側部５Ｄを含む下金属枠５Ａから離間した位置に配置される。突出部３５〜３７の下金属枠５Ａへの接触が許容される部分は、先端部（突端部）から対向部３９に接続する根元部までの部分である。一対の突出部３５、３６は、対向部３９の室外側で並列する。   The facing portion 39 does not contact the lower metal frame 5A, and the projecting portions 35 to 37 project from the facing portion 39 to the indoor side portion 5D. Due to the protruding portions 35 to 37, the facing portion 39 is arranged at a position separated from the lower metal frame 5A including the indoor side portion 5D. The portion where the protrusions 35 to 37 are allowed to come into contact with the lower metal frame 5A is a portion from the tip portion (projection portion) to the base portion connected to the facing portion 39. The pair of protrusions 35 and 36 are arranged side by side on the outdoor side of the facing portion 39.

下枠５において、空所３８Ａ、３８Ｂが第３下樹脂カバー３０の対向部３９と下金属枠５Ａの室内側部５Ｄの間に形成され、第３下樹脂カバー３０が突出部３５〜３７のみで下金属枠５Ａに接触する。そのため、第２実施形態の下枠５でも、第３下樹脂カバー３０の表面温度の低下を抑制して、第３下樹脂カバー３０での結露の発生を抑制でき、断熱性と防露性能を向上させることができる。なお、上枠６の第２上樹脂カバー５０に、中空部５１に替えて、対向部３９と同様の対向部を設けてもよく、縦枠７の第２縦樹脂カバー７０に、中空部７１に替えて、対向部３９と同様の対向部を設けてもよい。   In the lower frame 5, cavities 38A and 38B are formed between the facing portion 39 of the third lower resin cover 30 and the indoor side portion 5D of the lower metal frame 5A, and the third lower resin cover 30 has only the protruding portions 35 to 37.
