Description

本開示は、改装建具に関する。 This disclosure relates to refurbished building materials.

従来、建物躯体の開口部をリフォーム等で改装する方法として開口部に新たな建具を設置するカバー工法が採用されている。カバー工法において、建物躯体の開口部に設けられる既設枠と、既設枠の内周側に配置される新設枠と、開口部の下方において既設下枠及び新設下枠の間に配置される下枠アタッチメントと、を備える改装建具が知られている（例えば、特許文献１参照）。 Conventionally, a cover construction method has been adopted as a method for renovating openings in a building frame by remodeling or the like, in which new fittings are installed in the opening. In the cover construction method, a renovated fitting is known that includes an existing frame installed in the opening of the building frame, a new frame placed on the inner periphery of the existing frame, and a bottom frame attachment that is placed below the opening between the existing bottom frame and the new bottom frame (see, for example, Patent Document 1).

特許文献１の改装建具において、新設枠の室外側のレールの下部において、下枠アタッチメントの室外側段差部の上面に新設下枠の下面が配置されることで、下枠アタッチメントは、新設下枠の加重を受けるように構成されている。 In the renovated fittings of Patent Document 1, the lower surface of the newly installed lower frame is placed on the upper surface of the outer step part of the lower frame attachment at the lower part of the outer rail of the newly installed frame, so that the lower frame attachment is configured to bear the weight of the newly installed lower frame.

特開２０２１－１３４４８９号公報JP 2021-134489 A

特許文献１に記載の下枠アタッチメントは、既設下枠に固定されており、既設下枠の形状によっては、下枠アタッチメントの室内外方向（見込方向）の位置がずれてしまって、下枠アタッチメントの室外側段差部の上面に新設下枠の下面が配置されないことがある。そのため、既設下枠の形状が異なっている場合においても、新設下枠の加重を受けることが可能であることが望まれている。 The sill attachment described in Patent Document 1 is fixed to the existing sill, and depending on the shape of the existing sill, the position of the sill attachment in the indoor/outdoor direction (forward direction) may shift, and the lower surface of the new sill may not be positioned on the upper surface of the outdoor step part of the sill attachment. Therefore, it is desirable to be able to support the weight of the new sill even if the shape of the existing sill is different.

本開示は、既設下枠の形状が異なっている場合においても、新設下枠の加重を受けることが可能な改装建具を提供することを目的とする。 The purpose of this disclosure is to provide a renovated fixture that can withstand the weight of a newly installed sill even if the shape of the existing sill is different.

本開示は、建物躯体の開口部に設けられる既設枠と、前記既設枠の内周側に配置される新設枠と、を備える改装建具であって、前記開口部の下方において前記既設枠及び前記新設枠の間に配置されるアタッチメントを備え、前記アタッチメントは、室内外方向に延びるアタッチメント室内外方向延在板と、前記アタッチメント室内外方向延在板の室外側において下方に延びるアタッチメント下方延出板と、を有し、前記アタッチメントと別体で構成され、前記新設枠の加重を受けることが可能な加重受け部材であって、前記アタッチメント下方延出板の室外側の面に取り付けられ前記新設枠の下面に下方側から当接可能な加重受け部材を備える、改装建具に関する。 The present disclosure relates to a remodeling fixture comprising an existing frame provided in an opening in a building skeleton and a new frame disposed on the inner periphery of the existing frame, and an attachment disposed below the opening between the existing frame and the new frame, the attachment having an indoor/outdoor extension plate extending in the indoor/outdoor direction and an attachment downward extension plate extending downward on the outdoor side of the indoor/outdoor extension plate, and a weight-bearing member configured separately from the attachment and capable of bearing the weight of the new frame, the weight-bearing member being attached to the outdoor side surface of the attachment downward extension plate and capable of abutting against the underside of the new frame from below.

以上のように構成される改装建具１においては、既設下枠２２の形状によっては、例えば、図４に示すように、アタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａに、新設下枠３２の段差下面部３２２０の中段部３２２２の中段下面３２２２ａを載置することが可能である。一方、図２に示すように、図４に示す場合よりも、既設下枠２２の形状が異なっていることで、アタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａが室内側Ｘ２にずれて配置されて、アタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａに、新設下枠３２の段差下面部３２２０の中段部３２２２の中段下面３２２２ａを載置することができない場合がある。このような場合において、別体で構成される加重受け部材４２５をアタッチメント下枠４２の下方延出板４２４の室外側Ｘ１の面に固定することで、新設下枠３２の加重を受けることができる。よって、既設下枠２２の形状が異なっている場合において、加重受け部材４２５を取り付けたり取り外したりすることで、新設下枠３２の加重を受けることが可能であり、汎用性を高めることができる。 In the remodeled fitting 1 configured as described above, depending on the shape of the existing lower frame 22, for example, as shown in Figure 4, it is possible to place the middle lower surface 3222a of the middle part 3222 of the step lower surface part 3220 of the new lower frame 32 on the upper surface 4232a of the lower part 4232 of the step corner part 423 of the attachment lower frame 42. On the other hand, as shown in Figure 2, since the shape of the existing lower frame 22 is different from that shown in Figure 4, the upper surface 4232a of the lower part 4232 of the step corner part 423 of the attachment lower frame 42 is shifted to the indoor side X2, and the middle lower surface 3222a of the middle part 3222 of the step lower surface part 3220 of the new lower frame 32 cannot be placed on the upper surface 4232a of the lower part 4232 of the step corner part 423 of the attachment lower frame 42. In such a case, the weight of the newly installed lower frame 32 can be supported by fixing a separately constructed weight-bearing member 425 to the exterior side X1 surface of the downward extension plate 424 of the attachment lower frame 42. Therefore, if the shape of the existing lower frame 22 is different, the weight of the newly installed lower frame 32 can be supported by attaching and detaching the weight-bearing member 425, thereby increasing versatility.

本実施形態によれば、以下の効果が奏される。本実施形態の改装建具１においては、アタッチメント下枠４２は、室内外方向に延びる室内外方向延在板４２１と、室内外方向延在板４２１の室外側において下方に延びる下方延出板４２４と、を有し、アタッチメント下枠４２と別体で構成され、新設下枠３２の加重を受けることが可能な加重受け部材４２５であって、下方延出板４２４の室外側Ｘ１の面に取り付けられ新設下枠３２の下面に下方側から当接可能な加重受け部材４２５を備える。これにより、既設下枠２２の形状が異なっている場合においても、加重受け部材４２５を取り付けたり取り外したりできるため、新設下枠３２の加重を受けることが可能であり、汎用性を高めることができる。 According to this embodiment, the following effects are achieved. In the remodeled fitting 1 of this embodiment, the attachment lower frame 42 has an indoor/outdoor extension plate 421 that extends in the indoor/outdoor direction, and a downward extension plate 424 that extends downward on the outdoor side of the indoor/outdoor extension plate 421, and is configured separately from the attachment lower frame 42. The weight receiving member 425 is capable of receiving the weight of the newly installed lower frame 32, and is attached to the outdoor side X1 surface of the downward extension plate 424 and is capable of abutting against the lower surface of the newly installed lower frame 32 from below. As a result, even if the shape of the existing lower frame 22 is different, the weight receiving member 425 can be attached and detached, so that it is possible to receive the weight of the newly installed lower frame 32, and versatility can be improved.

本実施形態においては、アタッチメント下枠４２は、室内外方向延在板４２１と下方延出板４２４との間に配置される段差角部４２３を有し、段差角部４２３は、室内外方向延在板４２１よりも低い位置において室内外方向に延びる下段部４２３２を有し、加重受け部材４２５は、段差角部４２３の下段部４２３２の室外側Ｘ１において段差角部４２３の下段部４２３２の上面４２３２ａと同じ高さの位置において室内外方向に延びる加重受け上面４２５２ａを有する。 In this embodiment, the attachment lower frame 42 has a stepped corner portion 423 arranged between the indoor/outdoor extending plate 421 and the lower extending plate 424, the stepped corner portion 423 has a lower step portion 4232 extending in the indoor/outdoor direction at a position lower than the indoor/outdoor extending plate 421, and the weight bearing member 425 has a weight bearing upper surface 4252a extending in the indoor/outdoor direction at a position at the same height as the upper surface 4232a of the lower step portion 4232 of the stepped corner portion 423 on the outdoor side X1.

これにより、加重受け部材４２５の加重受け上面４２５２ａは、アタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａと高さが同じであるため、既設下枠２２の形状が異なっていてアタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａが室内外方向の位置がずれた場合において、アタッチメント下枠４２の段差角部４２３の下段部４２３２の上面４２３２ａにおいて新設下枠３２の加重を受けることができない場合であっても、アタッチメント下枠４２の室外側Ｘ１の位置において、加重受け部材４２５の延びる加重受け上面４２５２ａにおいて、新設下枠３２の加重を受けることができる。よって、加重受け部材４２５を別部材で構成して後から取り付けることができ、汎用性を高めることができる。 As a result, the weight receiving upper surface 4252a of the weight receiving member 425 is at the same height as the upper surface 4232a of the lower part 4232 of the step corner 423 of the attachment lower frame 42. Therefore, even if the shape of the existing lower frame 22 is different and the upper surface 4232a of the lower part 4232 of the step corner 423 of the attachment lower frame 42 is shifted in the indoor/outdoor direction, and the weight of the new lower frame 32 cannot be received by the upper surface 4232a of the lower part 4232 of the step corner 423 of the attachment lower frame 42, the weight receiving upper surface 4252a extending from the weight receiving member 425 can receive the weight of the new lower frame 32 at the outdoor side X1 position of the attachment lower frame 42. Therefore, the weight receiving member 425 can be made of a separate member and attached later, improving versatility.

本実施形態においては、加重受け部材４２５は、アタッチメント下枠４２の下方延出板４２４の室外側Ｘ１の面に固定される固定板４２５１と、固定板４２５１の上端部から室外側Ｘ１に延びる加重受け上面板４２５２と、を有する。これにより、加重受け部材４２５を簡易な構成にできるため、簡易な構成で、新設下枠３２の加重を受けることができる。 In this embodiment, the load-bearing member 425 has a fixed plate 4251 that is fixed to the surface of the outer side X1 of the downward extension plate 424 of the attachment lower frame 42, and a load-bearing upper plate 4252 that extends from the upper end of the fixed plate 4251 to the outer side X1. This allows the load-bearing member 425 to have a simple configuration, so that it can bear the load of the newly installed lower frame 32 with a simple configuration.

本実施形態においては、新設下枠３２の下面は、室内外方向に延びる中段下面３２２２ａを有し段差状に形成される段差下面部３２２０を備え、加重受け部材４２５は、中段下面３２２２ａに下方側から当接する。 In this embodiment, the lower surface of the new lower frame 32 has a stepped lower surface portion 3220 formed in a stepped shape with a middle lower surface 3222a extending in the indoor/outdoor direction, and the load-bearing member 425 abuts against the middle lower surface 3222a from below.

本実施形態においては、アタッチメント下枠４２の室内外方向延在板４２１は、新設下枠３２にネジ固定され、アタッチメント下枠４２の下方延出板４２４は、既設下枠２２にネジ固定される。これにより、アタッチメント下枠４２は新設下枠３２及び既設下枠２２の両方に固定されており、安定して固定されている。 In this embodiment, the indoor/outdoor extension plate 421 of the attachment lower frame 42 is screwed to the new lower frame 32, and the downward extension plate 424 of the attachment lower frame 42 is screwed to the existing lower frame 22. As a result, the attachment lower frame 42 is fixed to both the new lower frame 32 and the existing lower frame 22, and is stably fixed.
