To improve the fire protection performance of frame fittings.SOLUTION: In a frame assembly fitting 10 in which an end of an end plate 15 is fixed in a frame body consisting of vertical frames 11, 12 and horizontal frames 13, 14, front and back convex portions 16 and a central convex portion 17, and a pair of concave portions 18 formed between the front and back convex portions on both sides of the central convex portion are formed so as to extend over substantially the entire surface of the frame body, in the inner surface of the frame body, and at the end of the end plate, front and back convex portions 19 that are fitted each into a pair of concave portions on the inner surface of the frame body, and a central concave portion 20 formed between the front and back convex portions and accommodating the central convex portion on the inner surface of the frame are formed so as to extend over substantially the entire end of the end plate, respectively. Since two fitting points are formed in an assembly part, even if one fitting point burns out due to a fire, the members can be held at the other fitting point each other, and the fire prevention performance is improved. It is preferred that the same applies to the assembly part between the vertical frame and the horizontal frame (Fig. 4).SELECTED DRAWING: Figure 2
【課題】框組み建具の防火性能を向上させる。【解決手段】縦框１１，１２および横框１３，１４からなる枠体内に鏡板１５の端部が固定されてなる框組み建具１０において、枠体の内面には、表裏凸部１６と、中央凸部１７と、中央凸部の両側に表裏凸部との間に形成される一対の凹部１８とが、それぞれ枠体内面の略全般に亘って延長するように形成され、鏡板の端部には、枠体内面の一対の凹部に各々嵌合される表裏凸部１９と、表裏凸部の間に形成されて枠体内面の中央凸部を収容する中央凹部２０とが、それぞれ鏡板端部の略全般に亘って延長するように形成されている。組付け部において２箇所の嵌合箇所が形成されるので、一方の嵌合箇所が火災によって燃え抜けてしまったとしても、他方の嵌合箇所で部材同士を保持することができ、防火性能が向上する。縦枠と横枠との組付け部も同様にすると良い（図４）。【選択図】図２
