Description

TECHNICAL FIELD The present application relates to a coupling mechanism for office refractory cabinets.

2. Description of the Related Art Conventionally, when a plurality of office cabinets having shelves for documents and the like are arranged in a horizontal direction, side walls of the cabinets are used as a connecting means so that they do not fall down and the front surfaces are aligned. In this method, four holes are provided at intervals, and the side walls of the cabinet are fastened together by bolts and nuts through the holes.

However, since the side wall of the office cabinet described above is generally made of a single steel plate of, for example, about 0.8 mm, connection by bolts and nuts is relatively easy. However, if the side walls are filled with a refractory material between the outer and inner layer plates to make it thicker, as in a fireproof cabinet, it is not easy to connect bolts and nuts. However, due to the penetration of the connecting hole, the fire resistance is reduced by that amount, and there is a defect that causes corrosion and the like.

Means for Solving the Problems Therefore, in order to improve the above-mentioned conventional defects, the present application provides
A concave portion is formed within the thickness range of the wall plate on the upper surface side part of the fireproof cabinet made of a wall plate filled with a fireproof material between the outer layer plate and the inner layer plate, and the outer layer plate at that position is formed. A hole is formed, a cap nut is fixed to the inner surface of the outer layer plate so as to close the hole, and a connecting member is fitted so as to straddle between the adjacent recessed portions of the fireproof cabinet. The member is fixed by screwing the cap nut bolt, and the upper surface of the connecting member is covered with a cover plate.

The action is to join the side wall plates of a pair of adjacent refractory cabinets, fit a connecting member between the recessed portions of the adjacent refractory cabinets, and screw the bolts to the cap nuts. And the upper surface of the connecting member is covered with a cover plate.

Example Hereinafter, an example of the present application will be described in detail with reference to the drawings. (1) is equipped with double doors (2) and (3) that can be opened and closed on the front side, and a rolling wheel (4) and an adjuster (5) on the lower side. Shows a fireproof cabinet in which the and
Each of the wall boards including (2) and (3) is made thicker by filling a fireproof material (8) between the outer layer board (6) and the inner layer board (7), and this fireproof cabinet ( At the center position of the left and right side of the upper surface of 1), a rectangular recess (9) elongated in the front-rear direction is formed within the range of the thickness of the upper wall plate, the upper surface of which is defined by the sub-outer layer plate (10). Is covered. (11) is a hole formed at two positions in the front-rear direction of the sub outer layer plate (10), and a cap nut (12) is welded (13) to the lower surface of the hole so as to seal the peripheral part of the hole (11). Fixed by. (14) is a metal connecting member having a size almost twice as large as that of the recessed portion (9), and an inward U-shape bent to the left and right side portions at a height substantially equal to that of the recessed portion (9). Bent portions (15) and (16) are provided, and a hole (17) matching the hole (11) is provided in this. (18) is a synthetic resin cover piece interposed between the bent portions (16), (17) of the connecting member (14), and the bent portions (15), ( An engaging step portion (20) engaging with the upper inner edge of the upper portion (16) is provided, and a leg piece (21) is provided on the lower surface thereof. Reference numeral (22) is a bolt that is inserted into the holes (11) and (17) and screwed into the cap nut (12) to fix the connecting member (14) to the recess (9).

In the above, the lower part (19) is formed in the central part of the upper plate of the cover piece (18) via a step, and the cut grooves (19) ′ are provided on the lower surfaces at the left and right positions thereof. This is to obtain the piece (27) of the auxiliary member (25) described later by cutting the cut groove (19) '.

Then, a pair of fireproof cabinets (1) adjacent to each other on the left and right,
Fit the connecting member (14) between the recesses (9) and (9) of (1), insert the bolts (22) into the holes (11) and (17), and fit the cap nuts. By screwing on the (12), the pair of fireproof cabinets (1), (1) are connected at the upper surface thereof. Next, the cover piece (18) is interposed between the U-shaped bent portions (15) and (16), and thereby the bolt (22) is hidden.

As shown in FIG. 3, when the refractory cabinets (1) and (1) are not connected, the auxiliary member (25) is attached to the recess (9). This auxiliary member (25) is made of a metal that is shortened to the size of one concave portion (9) by omitting the middle portion of the connecting member (14), leaving the bent portions (15) and (16). A piece of
(26), the left and right engaging step portions (20) of the cover piece (18) and the left and right leg pieces (21) are left, and an intermediate portion thereof is omitted, and a single recess is formed.
It is composed of a synthetic resin piece (27) that is shortened to fit (9).

Effect of the Invention Since the present application has a structure in which the fireproof cabinets are connected to each other on the upper surface as described above, the connection work can be performed very easily regardless of the stored state of the contents, and the connection is surely performed. Moreover, since there is no protrusion on the upper surface of the fireproof cabinet, it is convenient to use because it is possible to place another cabinet on the upper surface of the cabinet body in a connected state, and it is provided on the outer layer board. The hole is
Since it is sealed with a cap nut, it has advantages such as impairing fire resistance and no fear of corrosion.
