Description

【０００１】
【発明の属する技術分野】
本発明は、建物の開口部構造および建物の開口部構造の施工方法に関するものである。
【０００２】
【従来の技術】
従来の技術として、特願平１０−２８７５６６号公報には、庇取付部材、庇本体、カバー材とで構成される窓庇が記載されている（従来技術−１）。
また、実公平２−３２７８１号公報には、主枠と、この主枠の上枠に結合される庇材とを備えた庇付きサッシ枠が記載されている（従来技術−２）。この庇材は、Ｌ形突条どうしの係合とネジにより主枠の上面に結合され、庇材の基部に家屋への取付用の上方折曲げ片を形成したものである。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来技術−１の窓庇は、庇取付部材、庇本体、カバー材とで構成されるので、部材数が多く、固定の手間がかかり、窓庇の有無によって取り付けられる建物側の部材が異なり、部品種類が多くかかるという問題がある。
また、従来技術−２の庇付きサッシ枠は、庇材の基部に家屋への取付用の上方折曲げ片を形成したものであって、この上方折曲げ片をどの様にして家屋へ取り付けるのか不明であるが、例えば、ビス等を使用するとビスが屋外に露出して外観性や防水の面で問題が生じることがある。
また、従来技術−２においては、主枠の上面に庇材を結合しているので、庇材の結合のために主枠を屋外側に突出させなければならず、このため、防水性や水切り性の関係から庇材なしの仕様にはできない。
【０００４】
本発明は、上記従来技術の問題を解決するためになされたものであって、庇の有無に関わらず防水性や水切り性を確保でき、施工性にもすぐれた建物の開口部構造および建物の開口部構造の施工方法を提供することを目的とする。

この結合部は、前記屋外側面から屋外側へ水平に延びる部分と、この部分から上方へ延びて前記上部に結合する部分とを有することを特徴とする。
【０００９】
請求項３記載の発明は、請求項１または２記載の建物の開口部構造において、前記建物が、箱形に組まれた建物ユニットを隣接配置して構築されるユニット建物であることを特徴とする。
【００１０】

In addition, Japanese Utility Model Publication No. 2-33271 discloses a sash frame with a hook provided with a main frame and a hook material coupled to the upper frame of the main frame (prior art-2). This saddle material is joined to the upper surface of the main frame by engagement of L-shaped ridges and screws, and an upper bent piece for attachment to a house is formed at the base of the saddle material.
[0003]
[Problems to be solved by the invention]
However, since the window fence of the above-mentioned prior art 1 is composed of the fence attachment member, the fence body, and the cover material, the number of members is large, and it takes time and effort to fix the building. However, there is a problem that many types of parts are required.
Moreover, the sash frame with a hook of the prior art-2 is formed by forming an upper bent piece for attachment to a house at the base of the saddle material, and how to attach the upper bent piece to the house. Although it is unknown, for example, when a screw or the like is used, the screw may be exposed to the outdoors, which may cause problems in terms of appearance and waterproofness.
Moreover, in the prior art-2, since the fence is bonded to the upper surface of the main frame, the main frame must be protruded to the outdoor side for bonding the fence. Because of the relationship of sex, it can not be made without specifications.

The building unit 100 was transported to the construction site, a unit building was constructed, and the fence 7 was installed on site.
[0028]
【The invention's effect】
According to the opening structure of a building according to claim 1, waterproofness can be ensured regardless of the presence or absence of a fence. In addition, it is easy to attach the kite and the workability is good.
[0029]
According to the opening structure of claim 1, further it can be secured draining property or without eaves.
[0032]
The building opening structure according to claim 3 , wherein the building is a unit building, and the waterproofing of the opening is completed on the opening frame side. Can also ensure the quality of waterproofing.
[0033]
Since the construction method of the opening part structure of the building of Claim 4 attaches the fence on-site, what protrudes from the surface of an outer wall panel is abbreviate | omitted, and transportation becomes easy.
In particular, when the building is a unit building, the transportation restriction of the building unit by the road traffic law can be avoided by attaching the fence to the site.
And even if the opening on the side in contact with the adjacent ground in a narrow site or the like is made free of wrinkles, quality such as waterproofing can be secured.
