DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of repairing a flush toilet room in a concrete building, and more particularly to a flush toilet room using a Japanese toilet with a step provided on a floor slab constituting a floor surface. And a method of repairing a flush toilet room that can be renovated into a flush toilet room using a Western toilet in a short time.

[0002]

2. Description of the Related Art In recent years, there has been a strong tendency to prefer Western style toilets over Japanese style toilets, and there have been many works of renovating existing Japanese style rooms such as condominiums into Western style toilets. I have. In the case of a Japanese-style toilet that is used for both toilets and urinals, steps are usually provided on the floor of the toilet room. To install a Western style toilet, remove the steps on the floor and flush the floor. (Tsuruichi) is required.

In the case of a concrete building, since the floor surface is constituted by a floor slab, a part of the floor slab must be removed in order to eliminate a step on the floor surface. A large opening that passes through the upper floor and lower floor will be formed in the trace where the is removed, so on fire protection, soundproofing,
From the viewpoint of preventing leakage, the opening must be closed by some means.

[0004]

The closing of the opening formed at the mark where a part of the floor slab has been removed is performed by casting concrete so as to have the same thickness as the floor slab. Usually, when concrete is cast, it takes a long time to cure and the process cannot proceed to the next step until the concrete is completely dried. This hindered the speedy progress of the entire renovation. Ideally, toilet room renovation work should be completed in one day from the viewpoint of cost. However, if the conventional method is used, it will take time to close the opening, so completion in one day is almost impossible. Was impossible,

[0005] For this reason, several construction methods capable of reducing the number of construction days have been proposed.
No. 5 is one of them. This Japanese Patent Application Laid-Open No. 11-270165
Is a kind of so-called dry method,
The opening on the mark where the floor slab was removed was not closed by casting concrete, but was closed by a fire-resistant cover, aiming to significantly reduce the construction time. is there.

However, simply closing the opening with the fireproof cover does not satisfy the fire protection standards stipulated in the Fire Service Law, so that it has not been practically possible to construct the fire legally. In a concrete building, the floor slab that divides the upper floor and the lower floor has a function as a fire protection compartment, and is required to have a fire resistance of 2 hours. Japanese Unexamined Patent Application Publication No. 11-2
In the refractory cover proposed in No. 70165,
No matter how much the material was devised, this two-hour fire resistance was not possible. Therefore, from the viewpoint of fire prevention, it cannot be said that the method proposed in Japanese Patent Application Laid-Open No. H11-270165 cannot be adopted.

The inventor of the present invention has conducted various studies in order to solve the above-mentioned problems relating to the renovation work of a Japanese-style toilet room into a Western-style toilet room. The present inventors have succeeded in developing a method of repairing a flush toilet room that can be completed by using the method described above, and propose the present invention as the present invention.

[0008]

A toilet room is constituted by a floor slab 1 and a wall surface 9. The floor slab 1 comprises a lower section 3 and an upper section 2, and a Japanese toilet 4 is attached to the upper section 2. In the repair work for replacing the Japanese-style toilet 4 in the flush toilet room with the Western-style toilet 26, the contact plate 11 was applied to the recess 6 formed on the back side of the upper section 2 from below and closed. After that, the upper step 2 of the floor slab 1 is removed by a filing operation, and is positioned toward the center of the opening 12 at an appropriate position on the periphery of the opening 12 of the removal trace and the wall 10 of the wall 9 facing the opening. A leg bolt receiving angle member 17 having a projecting piece 16 projecting horizontally,
A plurality of the overhanging pieces 16 are fixed so as to be substantially the same height as the upper surface of the lower section 3 of the floor slab 1. 1
The unit toilet pan 22 has an upper surface that is substantially the same height as the upper surface of the lower portion 3 of the floor slab 1, and then has a plate shape and has a plurality of extendable leg bolts 23 on the lower surface. The leg bolts 23 are placed on the overhanging piece 16 of the leg bolt receiving angle member 17 and on the upper surface of the lower portion 2 of the floor slab 1 so as to place the lower portion 2 of the floor slab 1 and the concrete striking. The above problem is solved by laying on the installation surface 19 and mounting and fixing the Western toilet 26 on the unit toilet pan 22.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a flush toilet room repair method according to the present invention will be described with reference to the drawings.

FIG. 1 shows a Japanese-style toilet room before renovation. A floor slab 1 constituting a floor is provided with a step, and an upper section 2 and a lower section 3 are formed. Japanese style toilet 4
Is installed.

In the method of repairing a flush toilet room according to the present invention, first, incidental parts such as a Japanese toilet 4 and a waste water pipe 5 attached thereto are removed. Thereafter, as shown in FIG. 2, an angle material having an L-shaped cross section from the back side of the lower section 3 of the floor slab 1 so as to surround the square recess 6 formed on the back side of the upper section 2 of the floor slab 1. 7 is fixed such that the horizontal projecting pieces 8 face inward, and then, as shown in FIG. 3, a backing plate 11 made of an iron plate or the like is provided between the angle member 7 and the lower surface 3 of the floor slab 1. The dent 6 is inserted into the gap and closed from the back side.

In this embodiment, the dent 6 is formed by inserting the backing plate 11 using the angle material 7.
However, the backing plate 11 may be fixed directly to the lower part 3 of the floor slab 1 with anchor bolts or the like.

Then, after waterproofing is performed between the backing plate 11 and the floor slab 1 by attaching a waterproof packing or the like,
As shown in FIG. 4, the upper step 2 of the floor slab 1 is removed by a filing operation, and the lower step end surface 13 of the floor slab 1 in the opening 12 formed by the filing operation is opposed to the wall surface 10 opposed thereto. Then, the reinforcing reinforcing bars 14 and 14 are driven in horizontally, and they are bound to form a reinforcing member. Note that the reinforcing reinforcing bars 14 and 14 are provided only for reinforcing the opening portion 12, and need not be particularly provided if sufficient strength can be maintained without providing the reinforcing bars.

Next, as shown in FIG. 5, the frays 15 generated by the fraying operation of the upper part 2 are put into the opening 12, and the surplus frays 15 are carried out. Further, as shown in FIG. 6, a leg bolt receiving angle member 17 having a projecting piece 16 projecting in the horizontal direction is provided on the peripheral edge of the opening 12 and the wall 10 of the wall 9 opposed thereto.
Are fixed so that the overhanging pieces 16 are substantially at the same height as the upper surface of the lower section 3 of the floor slab 1, and the concrete 1 is placed in the opening 12 into which the shears 15 are inserted.
8 is cast so that the casting concrete surface 19 is substantially flush with the upper surface of the lower portion 3 of the floor slab 1.
In addition, a ventilation opening 20 and a sewage pipe take-out opening 21 are formed in the wall 9 as necessary. In the figure, reference numeral 27 denotes an electric drill for drilling.

Thereafter, as shown in FIG. 7, the leg bolts 23 of the unit toilet pan 22 are placed on the upper surface of the lower portion 3 of the floor slab 1 and at predetermined positions of the leg bolt receiving angle members 17, respectively. Are laid horizontally on the upper surface of the casting concrete surface 19 and the lower portion 3 of the floor slab 1 with a certain interval therebetween. The unit toilet pan 22 is formed by stacking a square plate-shaped toilet pan main body 25 on a frame 24 assembled on a girder. From the four corners and the intermediate portion of the frame 24, the unit toilet pan 22 faces downward. Extendable and retractable leg bolts 23 are provided respectively.

The unit toilet pan 22 need not be laid before the casting concrete surface 19 is dried and solidified, but may be laid immediately after the casting and before the solidification. Further, since the leg bolts 23 of the unit toilet pan 22 are extendable and contractible, there is a slight difference in height between the upper surface of the lower portion 3 of the floor slab 1 and the upper surface of the projecting piece 16 of the leg bolt receiving angle member 17. However, by adjusting the amount of protrusion of the leg bolt 23, the leg bolt 23 can be laid while keeping the horizontal level accurately. After laying this unit toilet pan 22,
As shown in FIG. 8, the Western style toilet 26 is fixed thereon, and necessary plumbing work, electric work or finishing work is performed to complete the toilet room repair work.

The flush toilet room renovation method according to the present invention is constructed according to the above-described procedure, and the unit toilet pan 22 is not directly placed on the upper surface of the concrete placing place, but on the floor slab. Since it is supported by the upper surface of the lower step portion 1 and the leg bolt receiving angle member 17 and is laid in a floating state, the laid concrete can be laid without any relation to the dried and solidified concrete. After the concrete has dried and solidified,
Since it is integrated with the lower section 3 of the floor slab 1, the heat resistance becomes equal to that of the floor slab, and sufficient fire resistance is maintained.

[0018]

As described above, in the case of using the flush toilet room renovation method according to the present invention, it is not necessary to wait for the concrete to dry and solidify, so that the construction can be carried out, and the construction can be completed within one day. It can also be completed. In addition, the opening made after removing the Japanese toilet bowl is closed with a concrete of the same thickness as the floor slab, so that it is possible to maintain the same fire resistance as before the construction, and there are no legal restrictions such as the Fire Service Law. There is no problem and there is no danger of strength reduction.

As described above, when the flush toilet room repair method according to the present invention is used, the repair work of the flush toilet room, which previously required several days to complete, can be completed in only one day. In addition, it has sufficient fire resistance and has extremely high practicality for renovation and renewal of existing concrete apartment buildings.
