上記のような樹脂製建具は、枠体として四周に配置される4本の枠部材にそれぞれ金属製の補強部材が設けられているので、建具全体の重量が大きくなる。樹脂製建具は、ビスや釘等により躯体に固定されるが、重量が大きくなると固定部にも負担がかかる。また、部材が増えるためコストも増大するという課題がある。そして、合成樹脂製の枠体は、熱により軟化したり火炎により一部が焼失しても隙間が生じることを防止しつつ軽量化を図ることが求められている。   Since the resin-made fittings as described above are provided with metal reinforcing members on the four frame members arranged around the four sides as the frame body, the weight of the whole fitting is increased. The resin joinery is fixed to the housing with screws, nails or the like, but when the weight increases, the fixing portion is also burdened. Further, there is a problem that the cost increases because the number of members increases. The synthetic resin frame body is required to be reduced in weight while preventing a gap from being generated even if it is softened by heat or partially burned off by a flame.

本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、軽量化を図りつつも火炎に晒されても貫通しにくい合成樹脂製の枠体を備えた建具及び建具の取付構造及び建具を提供することにある。   The present invention has been made in view of such problems, and an object of the present invention is to provide a joinery and a joinery including a synthetic resin frame that is less likely to penetrate even when exposed to a flame while achieving weight reduction.
