DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookshelf, and more particularly, to a fire-resistant laminated bookshelf in which bookshelves are vertically stacked.

[0002]

2. Description of the Related Art As shown in FIG.
A floor (40) is provided on the bookshelf (10), and further on the bookshelf (10)
The bookshelf (10) and the floor (40) are alternately stacked in several layers, and are widely used in libraries, etc. because of their excellent storage capacity per unit volume and reduction in construction costs. I have. Furthermore, in order to increase the storage capacity, recently, a moving shelf that runs along a guide rail (not shown) provided on the floor (40) has been often used. Conventional laminated bookshelves generally comprise a bookshelf (10) of steel and a floor (40) of steel or concrete flooring.

[0003]

However, in recent years,
Fire resistance standards for large libraries containing large collections of books have become stricter, and the above standards cannot always be achieved using conventional laminated shelves. If the thickness of steel or concrete flooring is increased, the above criteria can be achieved, but the weight of the entire shelf increases, so the load-bearing strength of the building must be increased, and Will rise significantly. Therefore, there has been a demand for a fixed and movable book-type laminated book shelf with improved fire resistance without increasing the weight of the entire book shelf and without impairing the structural rigidity.

[0004]

According to the present invention, there is provided a laminated book shelf in which a beam is bridged between ends of a plurality of columns for assembling a book shelf and a floor is provided between the beams. And a fire-resistant board fixed to upper and lower surfaces of the floor plate. A plurality of refractory boards fixed to the lower surface of the floorboard are vertically stacked, and the joining position of the board in each layer is shifted from the joining position of the adjacent layer. The refractory board is a plate material mainly composed of calcium silicate. The support includes a core member and a refractory material covering the core member. The strut further includes a hollow outer member surrounding the refractory material. The lower part of the beam is fixed to an upper end of the core member, and a guide rail of a movable shelf is provided on the upper surface.

[0005]

1 to 3 show one embodiment of the present invention, which will be described with reference to the drawings of this embodiment.
Here, a part of a bookshelf (10) forming a lowermost layer which is one of a plurality of layers is shown. The bookshelf (10) has a plurality of columns (12) arranged at predetermined intervals, a number of shelves (20) installed between the columns (12), and attached to both sides of each shelf (20). And provided shelf support (22).

The shelf board (20) and the shelf support (22) have the same configuration as a conventional book shelf, and will not be described in detail. Prop (12), Fig. 3
A core member (13) having a rectangular cross section as shown in FIG.
3) a heat insulating refractory material (14) (for example, mainly composed of gypsum or glass fiber) covering the refractory material and a hollow outer member (15) having a rectangular cross section surrounding the refractory material (14); In the lower part of (12), a core member (13) is firmly fixed to the floor (19), and a hollow outer member (15) is provided below a lower end flange (16) under a liner plate (17) for level adjustment. ), And a flange (1
By bolts (18) penetrating holes provided in 6), floor (19)
It is fixed to.

The core member (13) of the column (12) is a force column for maintaining the rigidity of the bookshelf, and the hollow outer member (15) outside the core member (13).
Is provided with a bracket (21) to which a shelf support (22) is attached.In the vertical direction, depending on the number of stacked liner plates (17), regardless of the attachment level of the core member (13), the adjacent strut (12) The height of the bracket (21) can be adjusted according to the level between them.

As shown in FIGS. 1 and 2, the floor (40)
At the upper end of (12), the beam (42) fixed to the upper end of the core member (13) of the column (12) and erected between the columns (12) is adjacent to the beam (42). It comprises a plurality of floorboards (44) laid and spread while being in parallel.

The upper end of the core member (13) is connected to the beam (42) via a channel-shaped bracket (46) fitted from below the beam (42).
Each floor plate (44) erected between beams (42)
Is a bent step (4) that extends outward from the lower end of the beam (42).
3), both ends 45 in the longitudinal direction (one end is not shown in the drawing) are supported, and the floor plate (4) is supported.
4) and the bracket (46) for fixing the core member (13)
It is connected to the beam (42) by (48).

Above the beam (42), a guide rail (60) for mounting wheels of a movable shelf (not shown) is provided at the center of a cross section perpendicular to the longitudinal direction, and the channel material opens upward.
(61) are connected and fixed.

As shown in FIG. 1, the floor panel (44) has a cross section perpendicular to the longitudinal direction, with a channel-shaped upper part and a lower end part of the channel folded slightly inward, as shown in FIG. As such, at both ends (45) in the longitudinal direction, it is a hollow body formed by bending a steel plate so as to form a bent portion (47) bent downward, and has a heat insulating property and a light weight and The bending rigidity in the longitudinal direction is improved. The bent portion (47) of the floor plate (44) is connected to the beam (42) with a bolt (48).

On the upper surface of the floor plate (44), a required fire-resistant board (5
0) is laid, and furthermore, a flame-resistant, flame-retardant decorative flooring
(52) is laid.

At least two or more refractory boards (54) (eg, gypsum board, glass fiber board) are fixed to the lower surface of the floor plate (44), and the seams (56) of the upper and lower layers are vertically adjacent to each other. The seams of the boards of the different layers are offset from each other as shown in FIG. This prevents the flame and high-temperature gas from entering the joint (56), and enhances the fire resistance. A fire-resistant and flame-retardant decorative board (57) is attached to the lower surface of the lowermost layer of the fire-resistant board (54) on the lower surface of the floor panel (44).

[0014]

As described above, according to the present invention, a large number of columns (12) installed on the floor are filled with a heat-insulating refractory material around a core member (13) serving as a power column, and the bookshelf (10) Since the outer member (15) serving as a column supporting the shelf support (22) of the floor (40) is a double structure heat-insulated from the core member (13), the beam (42) of the floor (40) and the floorboard ( 44) is the shelf (20) or shelf holder (2
Since the outer member (15) that is in heat-transfer contact with 2) is assembled with the core member (13) without being in direct thermal contact, the floor (40), the floor plate (44), and the core member ( The safety of the books stored in the bookshelf (10) can be measured against the heat transmitted from (13). Further, since the floor panel (44) is hollow, the heat insulating property between the upper and lower bookshelves is excellent.

Further, the positions of the joints (56) of the fireproof boards (54) of the respective layers fixed to the lower surface of the floor (40) are shifted from each other, and the heat insulating properties against a flame or hot air from below are also improved. Has improved. Even if the upper stage is a mobile shelf, the guide rail (60) of the movable shelf is fixed above the beam (42) connected to the core member (13) with sufficient strength, so that sufficient rigidity is maintained. Dripping. As described above, the fire resistance of the laminated bookshelf according to the present invention is improved compared to the conventional laminated bookshelf without increasing its weight, and can sufficiently meet the demands of the laminated bookshelf that have been desired so far. is there.
