Description

TECHNICAL FIELD The present invention relates to a heat insulating material fixing hardware and a heat insulating wall.

2. Description of the Related Art Insulating walls are applied to buildings in which a plurality of insulating layers are interposed between an exterior material including ceramic or metal siding boards and an interior material such as a gypsum board. More specifically, heat insulation having a structure in which two layers of heat insulating material are provided, and an exterior material and an interior material are arranged on the outdoor side and the indoor side of these heat insulating layers via a ventilation layer or an air space. There is a wall, a heat insulating wall having a structure in which an exterior material and a ventilation layer, three layers of heat insulating material layers and an interior material are laminated in the wall thickness direction.

In a conventional heat insulating wall, a heat insulating material such as glass wool or rock wool is filled in the wall in order to form a plurality of heat insulating material layers between an exterior material and an interior material. However, in an insulated wall simply filled with an insulating material, for example, in the event of a fire, the insulating material will drop downward inside the wall after the fire spreads. In this way, when the heat insulating material spreads and falls down inside the wall, the space where the heat insulating material existed between the exterior material and the interior material becomes hollow, and the indoor side and the outdoor side are separated through the wall. It becomes easy for the flame to conduct heat between them. Therefore, there is a problem that it is difficult to realize a heat insulating wall with a fireproof specification of 60 minutes or 72 minutes. Here, the 72-minute fireproof specification means that when the heat of a fire is applied to the heated surface for 72 minutes, the temperature of the non-heated surface rises to a temperature at which combustible materials in contact with the non-heated surface may burn. Do not imply fire resistance specifications.

Here, when attaching the edge joist to the base, there has been proposed an edge joist support fitting that realizes easy positioning and fixing, and also enables attachment of a heat insulating material. Specifically, a substantially horizontal positioning piece that abuts on the top surface of the base, a hanging piece that hangs down from one end of the positioning piece, and a joist support piece that projects substantially horizontally from the hanging piece in the opposite direction to the positioning piece. , a substantially horizontal heat insulating material support piece for placing the heat insulating material, and a heat insulating material locking claw for locking the heat insulating material placed on the heat insulating material supporting piece (for example, Patent Document 1 reference).

JP-A-11-013258

The joist receiving hardware described in Patent Document 1 is originally a hardware that is applied when attaching a joist to a foundation of a floor, and is not assumed to be applied to a wall. Even if the joist receiving hardware described in Patent Document 1 is applied to the heat insulating wall, the heat insulating material locking claws merely lock the heat insulating material. It is difficult to prevent the fire-spreading heat insulating material from coming off.

According to this aspect, in a heat insulating wall provided with three layers of heat insulating material, when each layer of heat insulating material is fixed to a stud or a frame member by a unique heat insulating material fixing metal, fire spreads to all layers of heat insulating material. However, they are prevented from falling off, and a heat insulating wall with high fire resistance can be formed. Here, among the three layers of heat insulating material layers, the outdoor heat insulating material layer is filled in a frame member formed of a shaped steel material. Then, for example, in a factory or the like, the frame member filled with the outdoor-side heat insulating material layer (preset state) can be transported to the site and erected. Further, depending on the case, there is also a form in which the exterior material, the frame member, and the outdoor-side heat insulating material layer are pre-set integrally, transported to the site, and erected. The frame member has a basic configuration of a rectangular frame composed of, for example, vertical bars and horizontal bars, and one or a plurality of intermediate horizontal bars or intermediate vertical bars may be interposed therein.

In this way, of the three insulation layers, the outdoor insulation layer can be preset to the frame member, which is the main structural part of the insulation wall. Drop-off is prevented by being held. In addition, since the intermediate heat insulating material layer is fixed to the frame member via the heat insulating material fixing hardware, even if the fire spreads, the intermediate heat insulating material layer can be prevented from falling off by maintaining the fixed posture to the frame member. In addition, since the insulation material layer in front of the pillar and the insulation material layer on the interior side are fixed to the studs via their own insulation fixing metal fittings, even if the fire spreads, they will not fall off because the fixing posture to the studs is maintained. prevented. Therefore, it can be a heat insulating wall with a fireproof specification of 60 minutes or 72 minutes. In addition, although the pillar front heat insulating material layer is arranged in front of the pillar, it is a heat insulating material layer arranged on the indoor side in the same manner as the room side heat insulating material layer. The material layers form the same insulation layer. Therefore, the heat insulating wall of this aspect becomes a heat insulating wall having three layers of heat insulating material, namely, an outdoor heat insulating material layer, an intermediate heat insulating material layer, a front heat insulating material layer, and an indoor heat insulating material layer.

As can be understood from the above description, according to the heat insulating material fixing metal fittings and the heat insulating wall of the present invention, the heat insulating material layer is fixed to the frame members and studs forming the heat insulating wall by various heat insulating material fixing metal fittings. Even if the heat insulating material spreads fire, the heat insulating material is prevented from coming off, thereby forming a heat insulating wall excellent in fire resistance performance.
