Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel structure for an automatic warehouse, for example, and more particularly to a refractory material coating structure for coating the outer surface of the steel structure.

[0002]

2. Description of the Related Art Conventionally, in a building such as an automatic warehouse, there is a building in which a steel frame as a column member is exposed in the building and protrudes from a wall surface. A portion of such a column member exposed in the warehouse is usually covered with a fire-resistant material such as rock wool in order to improve the fire resistance of a building such as an automatic warehouse.

[0003]

However, rock wool is a relatively soft substance. Therefore, especially rock wool on a column base close to the floor is worn or peeled off by cleaning the floor with a vacuum cleaner or the like. easy. When a part of the rock wool is peeled off from the pillar member to expose the steel frame, the fire resistance of the building is reduced by itself. An object of the present invention is to provide a structure for preventing the fire resistance of a building from deteriorating due to peeling and abrasion of a refractory material of a column member.

[0004]

According to the present invention, there is provided a pillar member having a fire-resistant coating structure, wherein an outer surface of the pillar member is coated with a refractory material.
And covers the portion of the column member located near the floor
It is characterized in that only the surface of the refractory material is directly covered with a harder protective material than the refractory material.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
1 and 2 show an embodiment of the present invention. The column member 11 made of a steel frame extends vertically along the wall 12 and extends from the floor surface 13 to a ceiling (not shown). The outer surface of the column member 11 is covered with a refractory material 14 such as rock wool. The vicinity of the floor surface 13 of the pillar member 11, that is, the pillar portion is covered with a protective material 15 made of a material (for example, mortar) harder than the refractory material.

As shown in FIG. 2, the pillar member 11 may be provided on a flat portion of the wall 12 or may be provided on a corner portion thereof.
Is coated over the entire portion protruding inward from the wall 12, that is, the steel frame is not exposed. The protective material 15 is provided over the entire portion of the refractory material 14 close to the floor 13 (FIG. 1). That is, the refractory material 14 is not exposed near the floor 13.

Therefore, when the floor 13 is cleaned with a vacuum cleaner or the like, the refractory material 14 is covered with the protective material 15 and does not come into contact with the vacuum cleaner. Peeling is prevented, so that the fire resistance of the building is always maintained in a predetermined state. As described above, since the protective material 15 is for preventing the refractory material 14 from being peeled off or worn due to contact with a vacuum cleaner or the like, the height H (FIG. 1) of the protective material 15 depends on the height of the vacuum cleaner or the like. Is determined.

Although the protective material 15 is mortar in the above embodiment, any material can be used as long as it can protect the refractory material 14 from at least the vacuum cleaner, and various commercially available materials can be used.

[0009]

As described above, according to the present invention, there is obtained an effect that peeling and abrasion of the refractory material of the column member are prevented, and the fire resistance performance of the building can be maintained.
