Description

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

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。   Conventionally, by so-called remodeling (renovation), the performance of a building has been improved simply and inexpensively using existing fixtures. For example, refurbishment of doors, windows, and the like is performed by placing a new frame (renovation frame) on the inside of 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 and prevention of dew condensation, there is a demand for refurbishment that improves the heat insulation performance of fittings such as doors and windows. On the other hand, these indoor side frames are provided by a bridge member made of a resin having an indoor side frame arranged on the indoor side and an outdoor side frame arranged on the outdoor side which are separated from each other and having low thermal conductivity. There has been proposed a new frame formed by connecting the outer frame and the outdoor frame (for example, see Patent Document 1). According to this newly installed frame, the heat conduction between the indoor side frame and the outdoor side frame is blocked by the bridge material, so that excellent heat insulation performance can be obtained.

しかしながら、特許文献１に開示された新設枠では、火災時に、樹脂で構成されたブリッジ材が溶融するおそれがある。その場合には、室内側枠と室外側枠とが分離し、防火性能が大きく低下する。特に、室外側で火災が生じた場合には、室外側枠が分離して脱落するおそれがある。   However, with the new frame disclosed in Patent Document 1, there is a risk that the bridge material made of resin may melt in the event of a fire. In that case, the indoor side frame and the outdoor side frame are separated, and the fireproof performance is greatly reduced. In particular, when a fire occurs on the outdoor side, the outdoor frame may be separated and fall off.

本発明は上記に鑑みてなされたものであり、その目的は、火災でブリッジ材が溶融した場合であっても、室内側枠と室外側枠との分離を抑制可能な改装用建具を提供することにある。   The present invention has been made in view of the above, and an object of the present invention is to provide a refurbishment fixture capable of suppressing separation between the indoor side frame and the outdoor side frame even when the bridge material is melted in a fire.
