Description

The present invention relates to an interlayer refractory support that is installed in a gap between an end face of a floor portion and a wall surface of a wall facing the end face of the floor portion.

An interlayer refractory support that is installed in a gap (interlayer) between an end face of a floor portion and a wall surface facing the end face of the floor portion is known (see Patent Document 1).
The interlayer fireproof material support is a metal in which a plurality of hanger portions hanging from the upper surface of the floor slab (floor portion) to the end face are intermittently provided along the longitudinal direction of the end face of the floor slab, and the gap is closed in each hanger portion. The plate-making material is hung, and the fire-resistant material is placed on the metal plate-making material.

JP-A-2010-261232

The above-mentioned interlayer fireproof material support is an assembly type in which the installation work of each hanger and the installation work of the metal plate material are performed separately, and not only the installation work is troublesome, but also each hanger and the metal plate material are fixed. Therefore, it cannot follow the movement of the floor and walls during vibration (when the gap (interlayer) shrinks due to the movement of the floor and walls, the metal plate material moves upward), and the configuration is fragile. Will be.
In addition, since the refractory material is visible from above the interlayer refractory material support, not only is there a problem in terms of appearance, but it is also difficult to clean when dust or dirt collects on the refractory material. There was also the problem that it was easy to make the appearance worse. In addition, a tape such as aluminum tape is attached as a surface material on the upper side of the refractory material so that the refractory material is not visually observed. In this case, the tape is wavy (wrinkled) and attached. Therefore, the appearance is poor, and it is difficult to clean the tape when dust or the like collects on the tape, and the tape is torn by a falling object or the like.
The present invention provides an interlayer refractory support that is excellent in workability during installation, followability to movements of floors and walls, strength, appearance, and ease of cleaning.

The interlayer refractory support according to the present invention is an interlayer refractory support installed in a gap between an end face of a floor portion and a wall surface facing the end face of the floor portion, and accommodates the refractory material. The refractory material accommodating portion and the mounting portion are provided, and the refractory material accommodating portion extends along the longitudinal direction of the end face of the floor portion to close the upper opening of the gap and also covers the upper side of the refractory material. It is provided with a support portion that is provided so as to extend downward along the wall surface from one end side in a direction orthogonal to the longitudinal direction of the portion and then extends toward the end face of the floor portion to support the refractory material, and the length of the covering portion. The other end side in the direction orthogonal to the direction is mounted on the upper surface of the floor portion as a mounting portion and mounted on the floor portion.
Further, the interlayer refractory support according to the present invention is an interlayer refractory support installed in the gap between the end face of the floor portion and the wall surface of the wall facing the end face of the floor portion, and the refractory material is used. A refractory material accommodating portion and a mounting portion are provided, and the refractory material accommodating portion extends along the longitudinal direction of the end face of the floor portion to close the upper opening of the gap and covers the upper side of the refractory material. The cover is provided with a support that is provided so as to extend downward along the end face of the floor from one end in a direction orthogonal to the longitudinal direction of the cover and then extend toward the wall surface to support the refractory material. The other end side in the direction orthogonal to the longitudinal direction of is mounted on the wall as a mounting portion.
According to the interlayer refractory support according to the present invention, it is possible to provide an interlayer refractory support excellent in workability at the time of installation, followability to movement of a floor or wall, and strength. Further, since the cover portion is provided, the refractory material is not visually observed from the upper side, the appearance can be improved, and an interlayer refractory material support that is easy to clean can be provided.
Further, since the plate surface of the covering portion and the upper surface of the floor portion are located on the same horizontal plane or substantially the same horizontal plane, it can function as a parting material having a good appearance. Cleaning will also be easier.
Further, since the covering portion is located above the end face and the upper surface of the floor portion, the covering portion can function like a baseboard.
Further, since the refractory material accommodating portion is characterized in that an opening is formed between the extension end of the support portion and the covering portion, the refractory material can be easily put into the accommodating space of the refractory material accommodating portion through the opening. It can be inserted, and an interlayer refractory member in which the refractory material is housed in the refractory material housing portion can be easily manufactured.
Further, since the refractory material accommodating portion is characterized in that the extended end of the support portion is in contact with or connected to the covering portion, it is difficult for fire to reach the refractory material directly, so that the fire resistance performance can be improved.
