Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a double floor structure formed on the upper surface of a concrete slab that partitions an upper floor and a lower floor in concrete buildings such as condominiums and office buildings.

[Technical background of the invention and its problems]

Generally, concrete buildings such as condominiums and office buildings have upper and lower floors separated by concrete slabs.The upper surface of this concrete slab forms the floor of the upper floor, and the lower surface is used to hang ceiling panels using hangers. It forms a double ceiling on the lower floor.

Power lines such as electric light lines and outlet lines in each room,
Communication lines such as telephone lines and signal lines can be wired using the gap between the concrete slab and the ceiling panel, but if such a double ceiling space is used as a wiring space,
When changing partitions, redecorating a room, rearranging electrical appliances, etc., the wiring must be changed within the space with the double ceiling, and since this space is narrow, wiring work is extremely troublesome and construction costs are high. becomes expensive. For this reason, wiring is often routed along the ceiling surface or mold surface, and this has the disadvantage of being unsightly because the wiring is exposed to the inside.

On the other hand, if you try to change the piping for kitchen or air conditioning gas pipes, supply pipes, and drainage pipes when changing partitions, redecorating a room, or rearranging gas appliances or kitchen utensils, the above-mentioned wiring changes may occur. The work is even more troublesome than in the case of a pipe, and there is no need to run any piping while it is exposed on the floor, which is not only unsightly but also causes greater damage in the event of a gas or water leak.

For this reason, a common option for centralizing wiring and piping may be considered. In other words, this system forms a common groove on the top surface of a concrete slab, and in this common groove there are electric light lines and
Power lines such as outlet wires, communication lines such as telephone lines and signal 51, gas pipes for kitchen or air conditioning, and drainage pipes are centrally wired and installed. By forming grooves in the floor of the room, for example, vertically and horizontally, not only can wiring and piping work be concentrated in the common groove, but also when you want to change the piping or wiring, you can use the common groove to move it to the desired location. There are advantages such as improved appearance as the piping and wiring are not exposed, and damage can be reduced in the event of gas or water leakage.

However, if such a common trench is constructed by digging directly into the top surface of a concrete slab, special formwork and special work are required for slab construction, making the slab construction work time-consuming. It costs J! It has the disadvantage of being a box. In addition, this method reduces the thickness of the slab in the common groove area, which leads to a decrease in slab strength, and the layout of the common groove is fixed at the time of construction. However, there are drawbacks such as the degree of freedom of piping is restricted and it is difficult to obtain a desired arrangement when changing wiring or piping. If the thickness of the slab in the common groove area is increased, the lower surface of the slab in this area protrudes downward and becomes a nuisance.If the lower surface of the slab is made flush, the thickness of the slab other than the common groove area increases, causing the f[ There are problems such as an increase in fll.

(Purpose of the Invention) The present invention was made based on the above circumstances, and its purpose is to freely arrange the common ditch on the concrete slab and to freely arrange the layout of piping and wiring. A double floor structure that can be selected and changed, does not require any changes to the conventional slab, is extremely easy to construct, requires less construction time and construction cost, and can also be constructed on existing slabs. This is what we are trying to provide.

Further, the lid 11 is also provided with an opening 123 similar to the opening/closing lid 21 adjacent to the opening/closing lid 21. This opening/closing lid 23... can also be removed by inserting your finger into the hole 24 and pulling it up, and when it is removed at the same time as the opening/closing 121 described above, the notch 16 for drawing out wiring and piping will be opened. There is. In addition, this opening and closing! The upper surface of 23... is also the same surface as the upper surface of the floorboard 2.

In the communal groove 3 configured in this way, there are partition walls,
A pedestal 25 is housed therein. This pedestal 25 is made of a galvanized iron plate, is disposed along the common groove 3, and is supported by support legs 26. The frame 25 divides the common ditch 3 into upper and lower parts, and the lower part of this division serves as a piping passage 27 for passing the gas pipe 8, the water supply pipe 9, and the drain pipe 10, and the upper part is used for the electric light line 4. , a wiring passage 28 for guiding power lines such as the outlet line 5 and communication lines such as the telephone II 6 and signal line 7. On this pedestal 25, power supply IiI such as the electric light line 4 and outlet line 5, and communication lines such as the telephone line 6 and signal line 111 are mounted and wired.

On the upper surface of these floorboards 2... and common groove 3...,
The carpet 12 shown in FIG. 1 is laid down. The carpet 12 consists of a piece 12a laid on the floorboard 2 and a piece 12b laid on the common gutter 3.

The construction procedure for forming such a double floor will be explained based on FIGS. 5 to 8.

Concrete slab in new or existing building 1
A standard JI 30 is written on the top surface of the board, as shown in FIG. 5, depending on the route of the required common ditch. Next, as shown in FIG. 6, floorboards 2 are laid on both sides of the reference line 30 at a predetermined interval.

By installing the floorboards 2 at predetermined intervals W1, a common groove 3 is formed between these floorboards 2 along the reference line 30.
It is structured along the following lines. Wiring and piping are provided in such a common trench 3 as shown in FIG. When wiring and piping,
Not all the routes of the common ditch 3 will be used, and it is desirable to select and construct the route that provides the shortest distance for the required wiring and piping.

For wiring and piping, a wiring passage 28 and a piping passage 27 are used, as shown in FIG. Furthermore, there is no need to install the frame 25 in the common groove 3 used only for piping, and the frame 25 does not need to be installed in the common groove 3 used for wiring and wiring and piping.
Accommodates 5.

When the wires and pipes placed in the common groove 3 are pulled out above the floor surface, the wiring closest to the pull-out position.

Wires and pipes are led out from the pipe drawing notch 16.

When such wiring and piping work is completed, as shown in FIG. 8, the common groove 3 is covered with a lid 11 to cover the openings thereof.

In this case, the opening/closing lids 21 and 23 are not placed on the wiring and piping drawer notch 1G from which the wires and tubes are led out, but the wiring from which the wires and tubes are not led out, lSi! The tube drawer notch 16 is covered with an openable lid 21, 23. After that, the construction is completed by laying the jutan 12a and 12b.

In such a (8-component double floor), a common groove 3 is formed on the top surface of the concrete slab 1, so the concrete slab 1
No special construction or processing is required, making it easy to construct the concrete slab 1 in the case of new construction, and it can also be applied to the existing concrete slab 1. Moreover, the common groove 3 has a floor plate 2 on the top surface of the concrete slab 1.
Since it is constructed by placing ... at intervals, not only no special members are required to construct the common groove 3..., but also the layout of the common groove 1113 can be freely selected. This makes it possible to arrange the common trench 3 according to the route of piping and wiring. Therefore, the piping and wiring can be changed freely, and since the piping and wiring are not exposed, the appearance is improved.

Moreover, even when changing the wiring or piping of something that has already been wired or piped using the common ditch 3, the other parts of the common ditch 3 configured as described above or You can make changes using the available space in Ichikyo 11!3. In this case, just by opening the lid 11, the wiring
Piping can be changed and work is easy, and even if the wiring and piping drawer position changes, the opening and closing 11
By removing 21 and 23, wiring and piping can be done in the shortest distance.

Then, on the floorboard 2... and on the top surface of Mll, there is jutan 1.
2, the appearance will improve because the joint W43... and the floorboard 2... will not be visible.

Since such floorboards 2 form a double floor together with the slab 1, it becomes difficult for sound from the upper floor to be transmitted to the lower floor, and the soundproofing effect is improved.

Since the floorboards 2 are placed directly on the concrete slab 1, no special base material is required. Therefore, the number of types of parts used is small, and the number of types of construction work is also small, which simplifies the process. In addition, since the floorboards 2... are placed directly on the concrete slab 1, the floor height is low, and because they are joined to the concrete slab 1 with the concrete pond 20, the floorboards 2... do not slide laterally or jump up, and are stable. Excellent in sex.

Also, if the floorboard 2... is made of foamed concrete,
Because it is lightweight, it is easy to handle, and because it can be easily cut with a saw, it is easy to construct, and it also has the advantage of being excellent in sound absorption and insulation, which improves livability.

The common groove 3 is partitioned into a piping passage 27 and a wiring passage 28 by a pedestal 25, so that piping and wiring do not cross paths or come into contact with each other.

If water leaks in the meantime, the water will not come into contact with the wiring, so
There is no need to worry about AM or short circuits. Furthermore, by connecting a ground wire to the pedestal 25, it can also be used as a shield body.

In addition, opening/closing 121.23... is for gas pipes, supply/drainage pipes, and each V! ! Not only can you install wiring and open/close the lead-out section, but you can also install outlets, sensors, emergency lights, etc.

The present invention is not limited to the above embodiment.

For example, the common groove 3 is not limited to a straight line, but may be curved. Also, P instead of Jutan 12...
Tiles may be laid. Further, the common groove 3 is not necessarily divided by the frame 25, but if it is divided, it may be divided horizontally instead of vertically.

(Effects of the Invention) As explained above, according to the present invention, a common groove is formed on the top surface of a concrete slab, so there is no need for special construction or processing of the concrete slab, and construction of the concrete slab is easy in the case of new construction. It is easy to use and can also be applied to existing concrete slabs. Moreover, since the common ditch is constructed by placing floor plates on the top surface of the concrete slab with a distance of B, no special parts are required to form the common ditch, and the layout of the common ditch can be freely selected. This makes it possible to arrange common ditches according to the routes of piping and wiring.

Therefore, the piping and wiring can be changed freely, and since the piping and wiring are not exposed, the appearance is improved.

Additionally, since the floorboards and slab form a double floor, it is difficult for the sound from the upper floor to be transmitted to the lower floor, improving the soundproofing effect. For this reason, since the concrete slab does not need to be changed to the same extent as before, construction time is shortened and construction costs are reduced.

Particularly in recent years, the spread of office automation in office buildings has been remarkable, and for this reason, the layout of OAI devices is frequently changed on each floor of office buildings. In such a case, if the 2 m floor structure of the present invention is adopted, the 0AII cable can be routed in the common ditch, which has the advantage of being able to quickly respond to layout changes.
