Description

[Detailed description of the invention] This invention relates to a renovated satsushi with a soundproofing function.

The steel sash is being renovated and a new aluminum sash frame is fitted around its inner periphery. Conventionally, when installing a new aluminum sash frame, it is attached to an old steel sash frame without any anti-vibration material. Therefore, the sound insulation performance of the opening frame is not much different from the old steel sash. On the other hand, refurbished sashes are performed as a refurbishment of old steel sashes that have deteriorated, so they can be used as sashes with new functions or soundproof sashes with improved sound insulation performance. However, with the conventional method of attaching the opening frame of a renovated sash, even if the glass and stile of the shoji have improved soundproofing properties, the soundproofing effect may be diminished. The above points also apply to the construction of renovated sashes on old aluminum sashes.

Therefore, the purpose of this invention is to provide a refurbished sash with excellent soundproofing performance.

This invention is characterized in that in a renovated sash in which a splint is fixed to the old opening frame and a new opening frame is fixed to the splint, a vibration isolating material is interposed in the abutment area between the splint and the new opening frame. This is a renovated Satsushi.

Embodiments of this invention will be described below with reference to the drawings.

The inner periphery of the vertical frame 107A is formed to match the inner shoji 3 and outer shoji 4 of the sliding shoji (details are not explained), but this inner periphery changes depending on the window type. In this embodiment, a sliding shoji screen with soundproofing effect is fitted. Furthermore, although the embodiments frequently use machine screws for fastening, blind rivets may also be used.

Vibration isolation materials 17, 18, 21, 2 used above
For material 3, a material with vibration damping properties such as polyester elastomer or vibration isolating rubber is selected for the purpose of vibration damping.

In the renovated sash constructed in this way, an attachment frame is fixed to the old opening frame, and a new opening frame is fixed to the attachment frame. Since the new opening frame is elastically supported by vibration-proofing material on the supporting frame, the sound transmitted inside the new opening frame is suppressed by the vibration-proofing material. This has the effect of increasing transmission loss and lowering the sound pressure inside the room. Vibrations transmitted through the ground such as roads and railways cause buildings to vibrate, and even if stationary vibrations that resonate with the glass glass and oscillate are transmitted from the old opening frame to the support frame, they are attenuated by the vibration isolating material and reduced. Then, the mass ratio of the new opening frame within the opening frame and the frame for storing shoji etc. is increased.
