Japanese Patent Laying-Open No. 2015-86658

However, in the said patent document 1, the metal surrounding glass reinforcing core material is arrange | positioned adjacent to the outer surface material and inner surface material of a door. In addition, since only the heating foam material is disposed between the reinforcing core material around the glass and each surface material, the heat insulating performance is inferior to that of the heat insulating material.
Moreover, since the outdoor side glass pressing member made from aluminum is extended to the indoor side rather than the multilayer glass, heat insulation performance falls also in a frame part.
For this reason, in the lighting window part, there exists a subject that it is difficult to improve heat insulation performance, maintaining fire prevention performance.

  An object of the present invention is to provide a door and a fitting capable of improving heat insulation performance and fire prevention performance while having a daylighting window.

  The door body of the present invention includes a door body having an opening, a frame attached to the opening, and a glass that is held by the frame and disposed in the opening. A metal outdoor surface material and indoor surface material, a heat insulating core material disposed between the outdoor surface material and the indoor surface material, and an aggregate material disposed along the opening. Is configured to include a metal frame and a resin frame arranged on the indoor side of the metal frame, and the metal frame includes a metal holding portion arranged on the outdoor side of the glass, and A metallic prospective surface portion disposed along the outer peripheral surface of the glass, and the resin frame is disposed along the outer peripheral surface of the glass and the resin holding portion disposed on the indoor side of the glass. And an expected resin surface portion connected to the expected metal surface portion, The aggregate includes a resin aggregate and a metal aggregate, and the resin aggregate includes an outdoor piece disposed along the outdoor surface material, and an indoor piece disposed along the indoor surface material. A connecting piece connecting the outdoor piece and the indoor piece, wherein the metal aggregate is disposed at a position away from the indoor piece on the outdoor side, and faces the frame in the aggregate. The surface to be heated is provided with a heating foam material.

Here, the glass is used as a daylighting window of the door, and in consideration of heat insulation and fireproofing properties, a multilayer glass including fireproof glass such as netted glass is usually used.
According to the present invention, the aggregate disposed along the inner peripheral surface of the opening of the door main body serving as the daylighting portion of the door includes the resin aggregate and the metal aggregate, and the outdoor of the door The face material and the indoor face material are arranged along the outdoor piece and the indoor piece of the resin aggregate, and the metal aggregate is arranged at a position away from the indoor piece to the outdoor side. Since the metal aggregate is placed away from the indoor surface material, heat outflow between the indoor surface material and the metal aggregate can be reduced, and the metallic glass reinforcing core material is close to the outdoor surface material and the indoor surface material. The heat insulation performance can be improved as compared to the fittings of Patent Document 1 arranged.
Moreover, since the resin-made prospective surface part arrange | positioned along the outer peripheral surface of glass was provided, the resin-made prospective surface part can be protruded and provided in the outdoor side rather than the indoor surface of glass.

It is configured with. And the outdoor surface material 14 and the indoor surface material 15 of the door 10 are arrange | positioned along the outdoor piece part 132 and the indoor piece part 133 of the resin aggregate 130, and the metal aggregate 140 is on the outdoor side from the indoor piece part 133. It is located at a distance. Since the metal aggregate 140 is disposed away from the indoor surface material 15, heat flow between the indoor surface material 15 and the metal aggregate 140 can be reduced, and heat insulation is achieved as compared with the case where each surface material is attached to the metal aggregate. Performance can be improved.
In particular, in this embodiment, since the metal aggregate 140 and the indoor surface material 15 are separated by a size of about 1/3 of the expected size of the door 10, the heat between the metal aggregate 140 and the indoor surface material 15. Outflow can be reduced and heat insulation performance can be improved.
Moreover, since the prospective surface part 41 arrange | positioned along the outer peripheral surface 21C of the multilayer glass 21 was provided in the resin-made frame 40, the prospective surface part 41 of the resin-made frame 40 is made more than the indoor surface 21B of the multilayer glass 21 at least. It can be provided projecting to the outdoor side. For this reason, the connection position of the metal frame 30 and the resin frame 40 can be arranged on the outdoor side of the indoor surface 21B, and the arrangement position of the metal frame 30 can be on the outdoor side. Insulation performance can be improved.
Furthermore, in the web 141 of the metal aggregate 140, the heating foam materials 171 and 172 are provided on the surfaces of the frame 22 facing the prospective surface portions 31A to 31D of the frame 22 and the second prospective surface portion 412 of the prospective surface portion 41. When 171 and 172 foam, the gap between the metal aggregate 140 and the frame 22 can be closed. Thereby, the fireproof performance in the lighting window 20 can be improved.
Therefore, it is possible to provide the door 10 that is a door that can improve the heat insulation performance and the fire prevention performance, and the entrance door 1 that is a fitting, while having the daylighting window 20.

In addition, since the incombustible heat insulating material 160 is disposed across at least the plurality of brackets 150, the space between the brackets 150 can be closed with the incombustible heat insulating material 160. For this reason, the volume of the space that the heating foam material 173 provided facing the incombustible heat insulating material 160 needs to be closed when foaming is smaller than the case where the non-combustible heat insulating material 160 is not provided, and the amount of the heating foam material 173 Can be significantly reduced and the cost can be reduced.
