UNIT TYPE BUILTUP LIGHTWEIGHT HEAT-SOUND INSULATING SASH AND MANUFACTURE THEREOF

摘要

PURPOSE: To reduce the indoor temperature difference and prevent the dew condensation of a window by using a heat-sound insulating sash formed of hollow multilayer unit plates absorbing manufacturing dimensional errors and deformation caused by climate change, for the opening part of a building or the like. ;CONSTITUTION: Hollow unit plates absorbing manufacturing dimensional errors and flexural deformation caused by climate change are formed into appropriate size with the spacing of thin plates narrowed so as to be multi-layered and used for a sash. In this case, the thickness of the synthetic resin thin plate is to be 1.2mm or less, and the total thin plate light transmittance is to be 30% or more. At that time, the plane effective dimension at the time of normal temperature is 24 equally-divided parts of a sash of 3 x 6 feet formed of stiles 3, rails and mullions 6, 7 to form a unit type builtup lightweight heat-sound insulating sash 1. The normal temperature plane effective dimension of a unit plate for a laterally-framed sash for a Japanese style room is to be short side 138il2mm, long side 420±24mm, 408±24mm, 309±24mm, and for a rough-spaced sash, the long side 276±24mm, short side 210±12mm, 206±12mm, 204±12mm, and for a Western style room rough-spaced sash, long side 276±24mm, short side 200±12mm, 194±12mm, 182±12mm.;COPYRIGHT: (C)1996,JPO
