Description

[Detailed description of the invention] The invention provides a lower refractory layer 3 by disposing a refractory material such as cement at the lower part of the outer case 2 at the upper opening where the upper edge is attached to the opening edge 1 on the floor. , an upper refractory layer 6 fixed with a refractory material such as cement is provided on the upper outer periphery of an inner case 5 having a safe lid 4 on the upper surface, and an inner case 5 is placed inside the outer case 2.
The object of the present invention is to provide an underfloor safe which can be easily installed and installed by an on-site assembly method.

Conventional underfloor safes have a double structure with an outer case and an inner case, and the fireproof material such as cement placed in the space between these two cases is all integrated, which increases the weight of the unit and makes it difficult to install. This weight has been a bottleneck, making installation work difficult.

The present invention has been proposed in view of the above points, and will be described in detail below based on the illustrated embodiments.

The safe A is divided into an outer case 2 and an inner case 5, and a safe lid 4 is provided on the upper surface of the inner case 5.

11 is a dial lock.

The upper part of the outer periphery of the inner case 5 has a double structure and is provided with an upper refractory layer 6 by enclosing a refractory material such as cement inside.

Further, several bolt insertion holes 12 are provided on the bottom surface of the inner case 5.

22 is a backing, and 23 is a handle.

The outer case 2 in which the inner case 5 is housed is open upward, has a flange 13 protruding outward on its upper edge, and has an inner wall 14 protruding from the bottom downwardly. A removable or fixed lower refractory layer 3 is provided along the inner circumference of the outer case 2 by disposing a refractory material such as cement, and a refractory material such as asbestos is provided on the upper surface of the lower refractory layer 3. Then, an intermediate refractory layer 7 is provided.

Furthermore, a removable or fixed fireproof spacer 8 is arranged on the bottom surface of the outer case 2, which is surrounded by an inner wall 14 having the lower fireproof layer 3 on its outer periphery.

The fireproof spacer 8 is made of a fireproof material such as asbestos or calcium silicate, and is thinner than the lower fireproof layer 2, and is provided with a metal plate on at least its upper surface.

19 is a drain port. The installation work for this safe A is carried out as follows.

First, an aluminum support frame 9 is attached to the opening edge 1 on the floor surface, and a bottom mortar form 10 integrated with an L-shaped fitting 16 is hung down and fixed to the joist 15 at the bottom of the opening edge 1.

Then, mortar 17 is poured into the bottom mortar form 10 to a predetermined height from the ground.

As shown in the figure, the receiving frame 9 has two levels, upper and lower. A lid 18 for closing the floor surface is placed on the upper level, and a flange 13 on the upper edge of the outer case 2 is placed on the lower level. Place the outer case 2 under the floor before the mortar 17 hardens.
7. Embed the bottom of the outer case 2 into the inside.

Then, the anchor bolts 20 are driven into the mortar 17 to fix the outer case 2 and the mortar 17.

The anchor bolts 20 may be attached to the outer case 2 from the beginning, or if the lower fireproof layer 2 and the fireproof spacer 8 are removable, they may be driven in later.

The inner case 5 is placed in the outer case 2 fixed in this way, and the lower surface of the upper refractory layer 6 faces the upper surface of the intermediate refractory layer 7, and the bolts are inserted (through the bolts 21 through L12 and into the metal part of the refractory spacer 8 or the outer case. It is fastened to the inner wall 14 or bottom surface of 2.

Since the intermediate refractory layer 7 is made of a refractory material such as asbestos, it is compressed by being sandwiched between the upper refractory layer 6 and the lower refractory layer 3 during this compaction, and there is no gap between the upper and lower refractory layers 3 and 6. I try not to be able to do anything.

The present invention is constructed as described above, but the refractory layer provided between the outer case and the inner case is divided into upper and lower parts, with the upper refractory layer provided in the inner case and the lower refractory layer provided in the outer case. Therefore, the overall weight is the same as the conventional one, but since it is only necessary to carry it one by one during construction, the weight carried at one time is approximately half compared to the conventional one. This makes construction easier.
