Description

本開示は、建具枠に関する。 This disclosure relates to a joinery frame.

近年、サッシやドアなどの建具は、室外から室内への熱の伝達を抑える高い断熱性能が求められている。このため、建具の枠（建具枠）と障子との気密を確保するとともに、枠や障子の框の断熱性能の向上が求められている。特許文献１に開示された建具枠は、内部の中空部を室内側と室外側とに仕切るリブが設けられ、このリブによって室外から室内への熱の伝達を抑えるように構成されている。特許文献１に開示された建具枠のリブは、建具の見付け面と平行となるように設けられている。 In recent years, fittings such as sashes and doors are required to have high heat insulating performance that suppresses heat transfer from the outside to the inside. Therefore, it is required to secure the airtightness between the frame of the fitting (joining frame) and the shoji, and to improve the heat insulating performance of the frame and the stile of the shoji. The joinery frame disclosed in Patent Document 1 is provided with a rib that divides the hollow portion inside into the indoor side and the outdoor side, and the rib is configured to suppress heat transfer from the outdoor side to the indoor side. The rib of the joinery frame disclosed in Patent Document 1 is provided so as to be parallel to the finding surface of the joinery.

建具枠を介する室外から室内への熱の伝達では、建具枠における建物の躯体に固定されている側の方が、その反対側の障子が設けられている側よりも熱が伝達しやすい。このため、建具枠のリブが建具の見付け面と平行となるように設けられている場合には、リブの向きが建具枠の内部の温度分布に対応せず、室外から室内への熱の伝達を効率的良く抑えることが困難である。 In the heat transfer from the outside to the inside through the joinery frame, the side of the joinery frame fixed to the building frame is easier to transfer heat than the side on the opposite side where the shoji is provided. For this reason, when the ribs of the joinery frame are provided so as to be parallel to the finding surface of the joinery, the direction of the ribs does not correspond to the temperature distribution inside the joinery frame, and heat is transferred from the outside to the inside. It is difficult to control the temperature efficiently.

本開示は、室外から室内への熱の伝達を効率良く抑えることができる建具枠を提供することを目的とする。 It is an object of the present disclosure to provide a fitting frame capable of efficiently suppressing heat transfer from the outside to the inside.

上記目的を達成するため、本開示に係る建具枠は、躯体に固定される躯体固定部と、前記躯体固定部と中空部を介して対向して配置され、障子が対向する障子対向部と、前記躯体固定部と前記障子対向部との間に設けられ前記中空部を室内外方向に仕切る第１リブと、を有し、前記第１リブは、前記障子対向部側から前記躯体固定部側に向かって漸次室内側に向かう斜め方向に延びる斜め部を有する。 In order to achieve the above object, the fitting frame according to the present disclosure includes a skeleton fixing portion fixed to a skeleton, a skeleton fixing portion and a skeleton facing portion facing each other via a hollow portion, and a shoji facing portion facing the skeleton. It has a first rib provided between the skeleton fixing portion and the shoji facing portion and partitioning the hollow portion in the indoor / outdoor direction, and the first rib is from the shoji facing portion side to the skeleton fixing portion side. It has an oblique portion that gradually extends toward the indoor side.

建具枠１の第１リブ４７は、障子対向部４２側から躯体固定部４１側に向かって漸次室内１３側に向かう斜め方向に延びる斜め部４７２を有している。建具枠１を介する室外１４から室内１３への熱の伝達では、建具枠１における建物の躯体に固定されている側の方が、その反対側の障子２１が設けられている側よりも熱が伝達しやすい。建具枠１における建物の躯体に固定されている側とは、下枠３２では上下方向の下側、上枠３１では上下方向の上側、縦枠では幅方向の躯体に固定されている側である。すなわち、下枠３２は下部の方が上部よりも室外１４から室内１３へ熱が伝達しやすく、上枠３１は上部の方が下部よりも室外１４から室内１３へ熱が伝達しやすく、縦枠は幅方向の躯体に固定されている側の方が障子２１が設けられる側よりも室外１４から室内１３へ熱が伝達しやすい。第１リブ４７の斜め部４７２は、障子対向部４２側から躯体固定部４１側に向かって漸次室内１３側に向かう斜め方向に延びていることにより、第１中空部３２１の内部の温度分布に沿った形状となる。このため、本実施形態による建具枠１は、室外１４から室内１３への熱の伝達を効率よく抑えることができる。 The first rib 47 of the fitting frame 1 has an oblique portion 472 extending in an oblique direction gradually toward the chamber 13 side from the shoji facing portion 42 side toward the skeleton fixing portion 41 side. In the heat transfer from the outdoor 14 to the indoor 13 through the fitting frame 1, the side of the fitting frame 1 fixed to the building frame has more heat than the side on the opposite side where the shoji 21 is provided. Easy to communicate. The side fixed to the skeleton of the building in the joinery frame 1 is the lower side in the vertical direction in the lower frame 32, the upper side in the vertical direction in the upper frame 31, and the side fixed to the skeleton in the width direction in the vertical frame. .. That is, in the lower frame 32, heat is more easily transferred from the outdoor 14 to the indoor 13 than in the upper part, and in the upper frame 31, heat is more easily transferred from the outdoor 14 to the indoor 13 in the upper part than in the lower part. On the side fixed to the skeleton in the width direction, heat is more easily transferred from the outdoor 14 to the indoor 13 than on the side where the shoji 21 is provided. The diagonal portion 472 of the first rib 47 extends in an oblique direction from the shoji facing portion 42 side toward the skeleton fixing portion 41 side gradually toward the chamber 13 side, so that the temperature distribution inside the first hollow portion 321 can be adjusted. It will be shaped along. Therefore, the fitting frame 1 according to the present embodiment can efficiently suppress the heat transfer from the outdoor 14 to the indoor 13.

建具枠１では、第１中空部３２１に第１リブ４７と第２リブ４８との２つのリブが室内外方向に間隔をあけて設けられている。これにより、第１中空部３２１が３つの空間に仕切られるため、第１中空部３２１の室外１４から室内１３への熱の伝達を効率よく抑えることができる。 In the joinery frame 1, two ribs, a first rib 47 and a second rib 48, are provided in the first hollow portion 321 at intervals in the indoor and outdoor directions. As a result, the first hollow portion 321 is divided into three spaces, so that heat transfer from the outdoor 14 to the indoor 13 of the first hollow portion 321 can be efficiently suppressed.

建具枠１の第１リブ４７は、見付け板部４７１を有している。このような構成とすることにより、下枠３２において見付け板部４７１に水抜き孔３２３を容易に設けることができる。 The first rib 47 of the joinery frame 1 has a finding plate portion 471. With such a configuration, the drain hole 323 can be easily provided in the finding plate portion 471 in the lower frame 32.

建具枠１の障子対向部４２には、押縁が取り付けられる第１溝部３２６が形成され、第１リブ４７は、障子対向部４２における第１溝部３２６が形成された部分に接続されている。第１溝部３２６に押縁が設けられる場合、押縁を第１溝部３２６に工具で叩いて押し込むことになる。建具枠１に障子対向部４２と躯体固定部４１とに接続された第１リブ４７が設けられていることにより、押縁を第１溝部３２６に押し込む際の振動を第１リブ４７および躯体固定部４１を介して建物の躯体（外壁１１）に伝達することができる。このため、押縁を第１溝部３２６に取り付けることによる建具枠１の変形を抑えることができる。 A first groove portion 326 to which a ridge is attached is formed on the shoji facing portion 42 of the fitting frame 1, and the first rib 47 is connected to a portion of the shoji facing portion 42 on which the first groove portion 326 is formed. When the ridge is provided in the first groove 326, the ridge is pushed into the first groove 326 by hitting it with a tool. Since the fitting frame 1 is provided with the first rib 47 connected to the shoji facing portion 42 and the skeleton fixing portion 41, the vibration when the ridge is pushed into the first groove portion 326 is generated by the first rib 47 and the skeleton fixing portion. It can be transmitted to the building frame (outer wall 11) via 41. Therefore, it is possible to suppress the deformation of the fitting frame 1 by attaching the ridge to the first groove portion 326.

建具枠１の第１リブ４７は、躯体固定部４１における固定片４５が接続された部分に接続されている。これにより、第１リブ４７から躯体固定部４１に伝達される荷重を躯体固定部４１および固定片４５の両方から建物の躯体に伝達することができるとともに、建具枠１の強度を向上させることができる。 The first rib 47 of the joinery frame 1 is connected to a portion of the skeleton fixing portion 41 to which the fixing piece 45 is connected. As a result, the load transmitted from the first rib 47 to the skeleton fixing portion 41 can be transmitted from both the skeleton fixing portion 41 and the fixing piece 45 to the skeleton of the building, and the strength of the fitting frame 1 can be improved. can.
