Description

本発明は、改装サッシに関する。 The present invention relates to a modified sash.

従来、マンション等の建物の開口部に取り付けられた既設枠を改装する方法として、カバー工法が広く採用されている。このカバー工法によって改装された改装サッシでは、建物の開口部に取り付けられた既設枠に対して、その内周面を覆うように新設枠が取り付けられる（例えば、特許文献１参照）。 Conventionally, a cover method has been widely adopted as a method for refurbishing an existing frame attached to an opening of a building such as an apartment. In the refurbished sash refurbished by this cover method, a new frame is attached to the existing frame attached to the opening of the building so as to cover the inner peripheral surface (see, for example, Patent Document 1).

ところで改装サッシでは、既設枠に新設枠を取り付けるに際して、気密性を確保する観点から両枠間の隙間を塞ぐことが重要である。そのため、特許文献１の改装サッシでは、上横枠と左右の縦枠については、既設枠の屋外側部と新設枠の屋外側部との接合部に気密部材が設けられる。また下横枠については、水密性も確保する観点から、既設枠の屋内側部と新設枠の屋内側部にブラケットを介して気密部材が設けられる。 By the way, in the renovated sash, when attaching a new frame to an existing frame, it is important to close the gap between the two frames from the viewpoint of ensuring airtightness. Therefore, in the refurbished sash of Patent Document 1, for the upper horizontal frame and the left and right vertical frames, an airtight member is provided at a joint portion between the outdoor side portion of the existing frame and the outdoor side portion of the new frame. For the lower horizontal frame, an airtight member is provided via a bracket on the indoor side portion of the existing frame and the indoor side portion of the new frame from the viewpoint of securing water tightness.

しかしながら特許文献１の改装サッシでは、上述したように上横枠と左右の縦枠の気密部材が屋外側に設けられる一方で、下横枠の気密部材が屋内側に設けられる。そのため、これら気密部材で形成される気密ラインが枠の四周において連続しておらず、高い気密性を確保するのが困難であった。 However, in the remodeled sash of Patent Document 1, the airtight members of the upper horizontal frame and the left and right vertical frames are provided on the outdoor side as described above, while the airtight member of the lower horizontal frame is provided on the indoor side. For this reason, the airtight lines formed by these airtight members are not continuous in the four circumferences of the frame, and it is difficult to ensure high airtightness.

また、各枠の屋外側部には網戸の取付部材が取り付けられる等、表面が凹凸状に形成されている。そのため、上横枠と左右の縦枠において、枠と気密部材の接触性が不十分となるおそれがあり、高い気密性を確保するのが困難であった。 Moreover, the surface is formed in uneven | corrugated shape, such as the attachment member of a screen door being attached to the outdoor side part of each frame. Therefore, in the upper horizontal frame and the left and right vertical frames, the contact between the frame and the airtight member may be insufficient, and it is difficult to ensure high airtightness.

また、特許文献１の改装サッシでは、既設枠の屋内側部と新設枠の屋内側部とが連結金具により連結されるとともに、当該連結金具を覆うように新設額縁が既設額縁に取り付けられているものの、枠と連結金具はメタルタッチであるため、これにより十分な気密性を確保するのは困難であった。 Moreover, in the renovation sash of patent document 1, while the indoor side part of an existing frame and the indoor side part of a new installation frame are connected with a connection metal fitting, the new frame is attached to the existing frame so that the connection metal fitting may be covered. However, since the frame and the metal fitting are metal touches, it has been difficult to ensure sufficient airtightness.

本発明は上記に鑑みてなされたものであり、その目的は、従来よりも高い気密性を有する改装サッシを提供することにある。 This invention is made | formed in view of the above, The objective is to provide the renovation sash which has airtightness higher than before.
