Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a partition used for partitioning into a small room in a building having a relatively large floor area, which is provided for an office or an exhibition, and particularly relates to a partition having fireproof and fireproof performance using a transparent fireproof panel. .
[0002]
[Prior art]
When a large room is divided into small parts, it is not possible to change the size of the room by forming a part of the wall of the building. A partition that can change the size of the room is used.
[0003]
The partition is an opaque or transparent plate. When a widely partitioned room is partitioned more narrowly according to the user's request, the opaque plate-like body has a strong feeling of blockage, and thus a transparent partition is preferred in order to give a feeling of opening.
[0004]
Regardless of whether the partition is opaque or transparent, for reasons of disaster prevention, it is better for the partition to have fireproof performance, and there are cases where it is legally necessary to make it a fireproof partition.
[0005]
In order to allow the partition to be used as an indoor space on both sides, it is better to use the plate-like body used for the partition in a structure to abut.
[0006]
Furthermore, in order to realize an open space by using a transparent plate-like body for the partition, the transparent plate-like body used for the partition is used between the floor surface and the ceiling surface without using a frame or the like. It was preferred to use a structure in which the plate-like body and the plate-like body are abutted.
[0007]
Such a structure that supports the plate-like body by abutting is a structure that is widely used for the outer wall of a building. When the plate-like bodies are butted and used for the outer wall, for example, as shown in FIG. 10, the plate glass 26 is made up of the T-shaped portion 23 b and the base aggregate portion 23 a that are vertically formed by the stand 23 supported by the structural member of the building. In between, it is supported by a sealant 24. The support structure that is used for such an outer wall, butted with a plate-like body, can also support a considerably heavy plate-like body, but since the vertical base aggregate 23a protrudes into the room, the outer wall In FIG. 23, the portion 23a, which was not so much of a problem, becomes very troublesome.
[0008]
For this reason, when providing a fireproof panel for a partition, as shown in the horizontal sectional view of FIG. 11, the base aggregate 4 is disposed between the ends of the fireproof panels 3, 3, the flame retardant backup material 5, and the nonflammable material. The fireproof panel 3 is supported by fixing the pressing plate 10 to the base aggregate 4 with screws 8 through the conductive backup material 6 and the fireproof heat insulating material 7.
[0009]
Furthermore, since the presser plate 10 and the screw 8 are poor in appearance, a gap holding member 9 is provided and covered with the decorative plate 11.
[0010]
[Problems to be solved by the invention]
The structure for using the fireproof panel as a partition mentioned above has a sufficient strength to support a large area fireproof panel because it is difficult to use a thick base aggregate to reduce the protruding part to the room. There is a problem that it is difficult to hold, and there are many types of members and man-hours such as using metal fittings, screwing, pressing plates and decorative plates.
[0011]
[Means for Solving the Problems]
The mounting structure of the plate-shaped body of the present invention is a mounting structure of a plate-shaped body used for partitioning a room, wherein the plate-shaped body is a transparent fire-proof panel and uses two T-shaped brackets having a T-shaped cross section. The T-shaped bracket is fixed on the floor and ceiling, the two T-shaped brackets face each other in an H shape, and the groove formed by facing the T-shaped brackets is flame retardant. or through the non-combustible backup material, a mounting structure of the plate-like body used for end-proof refractory panels from both sides partition having an anti-fire performance, characterized in that for clamping in the T-shaped fitting.
[0012]
Further, in the above-described partition plate mounting structure, the T-shaped bracket is separated by an air layer or a non-combustible heat insulating material, and is parallel to the fireproof panel of the T-shaped bracket. The plate-like body mounting structure is characterized in that the portion has a hollow structure or a thick central portion.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The structure of the partition of this invention uses a transparent fireproof panel as a partition. The fireproof panel is an applied product of sheet glass and sheet glass used for the Class A fire door or the Class B fire door, such as a meshed glass, a tempered glass, or a gel fireproof glass.
[0014]
Since the partition using the above-mentioned transparent fireproof panel is transparent, it gives a feeling of opening to the space narrowed by the partition and prevents the spread of fire at the time of fire.
[0015]
The fireproof panel is configured so that two T-shaped metal fittings face each other in an H shape, and an end portion is sandwiched in a formed groove through a backup material.
[0016]
T-shaped fittings are made of stainless steel, iron, or other metals or ceramics, and their cross-sectional shape provides high bending rigidity, prevents the fireproof panel from bending, and supports the fireproof panel even when the weight is reduced. Of sufficient strength. The cross-sectional shape is preferably determined by performing a simulation by means such as material mechanics or a bending test so as to have sufficient bending rigidity to support the size of the fireproof panel. Further, the portion disposed on the indoor side of the T-shaped metal fitting can be given a design property while increasing the bending rigidity by increasing the thickness of the central portion or by forming a hollow structure. Furthermore, it is desirable that the surface of the T-shaped bracket disposed on the indoor side is mirror-finished or painted to improve the appearance.
[0017]
The portion of the T-shaped metal fitting inserted between the ends of the fireproof panel is supported by the fireproof panel in a state of being separated by a nonflammable heat insulating material or an air layer. When the T-shaped bracket is separated by an air layer or a heat insulating material, the heat transfer in the T-shaped bracket is reduced in the event of a fire, and the temperature rise in the non-spreading compartment is suppressed and evacuation is facilitated. It is preferable because it also has the effect of delaying the spread of fire, such as suppressing ignition of combustible materials. This is particularly effective when a fireproof glass having a heat shielding effect, such as a fireproof glass containing water-containing gel, is used. As the heat insulating material, it is desirable to use a nonflammable material such as ceramic short fiber, ceramic fiber, rock wool, or gypsum board.
[0018]
The T-shaped bracket is fixed to the floor surface and the ceiling surface. Fixing is performed by fitting a T-shaped metal fitting into a groove formed on the floor or ceiling surface, or using a metal metal fitting such as stainless steel or iron.
[0019]
As the backup material, an incombustible or heat-insulating backup material is used.
[0020]
As a nonflammable backup material, it is necessary to prevent the flame from penetrating. Ceramic fibers, ceramic short fibers, rock wool, etc. can be used between the T-shaped brackets at the position where the end face of the fireproof panel touches. .
[0021]
The flame retardant backup material is used to maintain the surface clearance of the fireproof panel and the T-shaped bracket, and a flame retardant sealing material can be used.
[0022]
The mounting structure of the plate-like body of the present invention is intended for fireproof panels, but other than fireproof panels, transparent and opaque plate-like bodies such as plate glass, plastic plates, metal plates, wooden plates, etc. It is a structure that can be used to attach the plate-like body when used for a partition.
