Description

本発明は、改装用建具に関する。 The present invention relates to a fitting for renovation.

従来、いわゆる改装（リフォーム）によって、既設の建具を利用して簡易で安価に建物の性能を向上させることが行われている。例えば、ドアや窓等の改装は、既設枠の内側に新設枠（改装用枠）を重ねて配置することにより行われる。 2. Description of the Related Art Conventionally, the performance of a building has been easily and inexpensively improved by using existing fittings by so-called remodeling. For example, remodeling of doors, windows, etc. is performed by stacking a new frame (remodeling frame) inside an existing frame.

ところで近年では、省エネや結露防止等の観点から、ドアや窓等の建具の断熱性能を向上させる改装が望まれている。これに対して、互いに離間する室内側に配置される室内側枠と室外側に配置される室外側枠とを有するとともに、熱伝導率が低い樹脂で構成されるブリッジ材により、これら室内側枠と室外側枠とを連結してなる新設枠が提案されている（例えば、特許文献１参照）。この新設枠によれば、ブリッジ材によって室内側枠と室外側枠との間での熱伝導が遮断されるため、優れた断熱性能が得られる。 By the way, in recent years, from the viewpoint of energy saving, prevention of dew condensation, etc., refurbishment has been desired to improve heat insulating performance of fittings such as doors and windows. On the other hand, the indoor side frame is provided by a bridge material that has an indoor side frame and an outdoor side frame that are disposed on the outdoor side and are spaced apart from each other, and that is made of a resin having a low thermal conductivity. There has been proposed a new frame in which the outer frame and the outdoor frame are connected (for example, refer to Patent Document 1). According to this new frame, since the bridge member blocks heat conduction between the indoor side frame and the outdoor side frame, excellent heat insulation performance can be obtained.
