Description

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

BACKGROUND ART An interlayer refractory material support that is installed in a gap (interlayer) between an end face of a floor and a wall surface of a wall facing the end face of the floor is known (see Patent Document 1).
The inter-layer refractory material support is provided intermittently along the longitudinal direction of the end surface of the floor slab with a plurality of hangers that hang down from the upper surface of the floor slab (floor) to the end surface. It is constructed by laying plate materials and placing a refractory material on the metal plate materials.

JP 2010-261232 A

The inter-layer refractory material support described above is an assembly type in which the work for installing each hanger and the work for installing the metal plate are performed separately. Therefore, it cannot follow the movement of the floor and walls during vibrations (if the gap (interlayer) shrinks with the movement of the floor and walls, the metal plate moves upward), making it a fragile structure. becomes.
In addition, since the refractory material is visible from above the refractory material support between layers, not only is there a problem in terms of appearance, but it is also difficult to clean if dirt or dust accumulates on the refractory material. , there is also a problem that the appearance tends to be further deteriorated. Also, in order to hide the refractory material, a tape such as aluminum tape is pasted as a surface material on the upper side of the refractory material. Since the tape is stored away, the appearance of the tape is poor, and if dust or the like accumulates on the tape, it is difficult to clean the tape.
The present invention provides an interlaminar refractory material support that is excellent in workability during installation, ability to follow movements of floors and walls, strength, appearance, and ease of cleaning.
