FIG. 3 is an enlarged view of a seal portion by the tongue-shaped seal 5a in FIG. 1A, and FIG. 4 is an enlarged cross-sectional view of an example in which the present invention is applied to the tongue-shaped seal 5a. The seal body 50 of 5a is formed of a fire-resistant or flame-retardant material, and a fire-resistant or flame-retardant core material 51 is embedded in the seal body 50. In particular, in the case of the figure, the core material 51 is uniformly embedded in the base portion 50a and the tongue-like portion (lip portion) 50b of the seal body 50 constituting the attachment portion of the tongue-like seal 5a to the vertical frame 13 or the like. is there.

  The seal body 50 can be made of various materials as long as it has fire resistance or flame retardancy, for example, fire resistant or flame retardant resin, specifically, heat resistant fiber such as ceramic fiber. Resin such as PVC can be used. The core material 51 may be made of various materials as long as it is fire-resistant or flame-retardant, but it is preferable to use a net-like body such as various nets. Specifically, for example, a metal net such as stainless steel is used. Alternatively, it is possible to use a net formed of a fire-resistant or flame-retardant fiber such as glass fiber, ceramic fiber or rock wool.

  The core material 51 embedded in the seal body 50 is a seal body in a state in which the whole is integrally formed or partially formed separately as a separate body and is integrally connected by stitching, bonding or other appropriate means. What is embedded in 50 or partially formed separately may be embedded in the seal body 50 as it is.

  As described above, the tongue-shaped seal 5a, which is a building sealing member according to the present invention, has a fire-resistant or flame-retardant core material 51 embedded in a seal body 50 formed of a fire-resistant or flame-retardant material. Even if a fire or the like occurs and the entire seal 51 is burned, the seal body 50 is made of a fire-resistant or flame-retardant material, so that it may be carbonized or weakened. Even if the seal body 50 is carbonized or weakened, the shape as a seal member can be maintained by the fire-resistant or flame-retardant core material 51 embedded in the seal body 50. .

  As a result, for example, when the tongue seal 51 is provided between the vertical frame 13 of the opening frame 1 and the vertical rod 23 of the joinery frame 20 in FIG. 1, the shape of the seal 51 is maintained even after a fire occurs. Thus, it is possible to satisfactorily prevent the smoke and flame from flowing from the gap S between the vertical frame 13 and the vertical gutter 23 to the inside and outside of the building. As a result, for example, it is possible to clear the flame retardant test of the building interior material and construction method according to JIS-A1321, and the fire test of the building fire door according to JIS-A1311.

  The seal member 5, particularly the seal body 50 as described above, is generally manufactured by extrusion molding with various resins including synthetic rubber and natural rubber, but a net-like body such as a net is used as the core material 51. When simultaneously extruded, the seal bodies 50 and 50 on both sides of the core member 51 can be integrated via the resin of the seal body 50 that has penetrated into the mesh of the mesh body, and has high durability. A seal member can be obtained.

  In addition, although the said embodiment was applied to the tongue-shaped seal 5a which consists of a single tongue interposed between the vertical frame 13 and the vertical hook 23 in the said FIG.1 and FIG.2, the vertical frame 14 and the vertical hook 34 It can also be applied to the tongue-shaped seal 5a interposed between the two and the tongue-shaped seal 5b composed of two tongues interposed between the vertical rod 24 and the vertical rod 34. Further, the present invention can be applied to a tongue-shaped seal 5c composed of a single downward tongue interposed between the upper rail 11a and the horizontal ribs 21 and 31 and / or between the horizontal frame 11 and the horizontal ribs 22 and 32. It is.

  FIG. 5 shows an example thereof. FIG. 5 (a) is an example applied to the tongue-like seal 5b composed of the above-mentioned two tongues, and FIG. 5 (b) is applied to the tongue-like seal 5c consisting of the above-mentioned one downward tongue. This is an example. In any of the above cases, in the same manner as in the above example, the tongue-shaped seals 5b, 5c are also installed in the base 50a and the tongue-shaped portion (lip portion) 50b of the seal body 50 that constitutes the mounting portion for the vertical rod 24, the horizontal rod 21 and the like. The core material 51 is embedded uniformly. The material and arrangement configuration of the seal body 50 and the core material 51 are the same as those in the above embodiment, and the same effects are obtained.

  The present invention is not limited to the tongue-shaped seal as described above, but can be applied to a sealing member such as the glazing channel 5d as shown in FIGS. 1 and 2, and FIG. A core material 51 is embedded in the seal body 50 constituting the channel 5d. Also in this example, the core member 51 is uniformly embedded in the base portion 50a and the bottom portion 50c of the seal main body 50 that constitutes the attachment portion of the seal member (glazing channel) to the vertical rod 23 and the like. The material, arrangement configuration, and the like of the main body 50 and the core material 51 are the same as in the case of the above-described embodiment, and the same operational effects can be obtained.

  Furthermore, the protrusion 23a such as the vertical rod 23 that engages and holds the glazing channel 5d as described above has less air insulation action by the hollow portion than the hollow portion 23b of the vertical rod 23 (see FIGS. 3 and 7). Therefore, for example, as shown in FIG. 7, it is desirable to provide a heat shielding seal member 5e as shown in FIG. 7 separately from or integrally with the glazing channel 5d. However, such a heat-insulating seal member 5e also has the same effect as described above when the core material 51 is embedded in the seal body 50 in the same manner as described above.

  Further, the present invention is not limited to the sealing members as shown in the above drawings, but various architectural seals such as various weather strips, various sealing members omitted in the drawings, various packings such as glazing beads, and gaskets. The present invention can also be applied to members, and the same effects as described above can be obtained.

  As described above, according to the architectural seal member of the present invention, even if a fire or the like occurs and the entire seal member is burnt, the seal body 50 of the seal member 5 is formed of a fire-resistant or flame-retardant material. Therefore, even if it is carbonized or weakened, it does not disappear, and even if the seal body 50 is carbonized and weakened, it is a fire-resistant or flame-retardant core material embedded in the seal body 50 The shape as a seal member can be maintained by 51. As a result, it is possible to satisfactorily prevent smoke and flames from flowing inside and outside the building from the gap between the members with the seal member 5 interposed therebetween, and it can be effectively used industrially. It can be done.
