Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, it is possible to install one outlet for low power or one outlet for high power on nine passages, and to reduce the number of wirings using buried pipes, moldings, etc.

This invention relates to a floor penetrating member for wiring.

+rP for offices, department stores, banks, etc. where the floor space is large
)-1-i1. ．． J-1/7 Mountains ・ノ を-HRTAHEN) The light power wires for the telephones, etc., are being pulled up from the floor. The method involves embedding the 70 arbox and electrical conduits in the floor, installing high-power outlets and low-power outlets in the floor box, and then wiring to the desired location. So-called floor
In the box method, floor ducts are buried in the floor in a vertical and horizontal cross pattern at intervals of 4 to 5 m, and outlets for heavy electricity and outlets for light electricity are installed in the floor duct at 60 crn intervals. ) K installation and wiring from there at the desired location.There is a method using a so-called floor duct.

In both cases, the wires can only be taken out from the floor ZX or the wire outlet via one high-power outlet or one low-power outlet, so it is inevitable that the wires must be hidden using buried pipes or exposed using moldings, etc. from the take-out point to the place of use. is required. Therefore, a large amount of construction cost is required for laying underground pipes, moldings, etc.

If the floor, floor, or wire outlet is located in the 9th aisle instead of under the desk, etc.

Power and light power outlets and exposed wiring protrude above the floor, which obstructs one-way traffic and poses a tripping hazard. Furthermore, exposed wiring can be stepped on and cause wiring failures.

In order to eliminate the above drawbacks, it is best to place a large number of floor boxes or narrow the spacing between floor ducts when constructing a new building, but floor boxes and lower ducts are expensive, so I can't hire it at all.

The present invention was made for the purpose of solving the drawbacks of the prior art, and the floor penetrating member for wiring of the present invention has a knock lid that is removed from the top when wiring is fixed to the formwork material. The flange is formed into a folding flange, and the ξ-eve for wiring is placed upright on the flange with the knock lid as the center, and when wiring, the outlet for light electricity or the outlet for heavy electricity is screwed, and the # flange is attached to the formwork material. The insert cap is screwed onto the wiring chisel to prevent the insert cap from being screwed on when wiring is not performed after it has been fixed.

Hereinafter, this invention will be explained based on all the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.

1 is a flange with a dowel hole 1A drilled in its center.
9. A plurality of fixing holes 1B for fixing the flange 1 to the formwork material are formed on its outer periphery. A 1.5 m/m iron plate is used as the flange 1, and the shape of the flange 1 is shown to be square, but it may have a shape other than that.

A knock lid 1C is formed by one knock hole.

Knock lid 1C is used when pouring concrete.

This is to prevent concrete from entering the wiring/ξ-beam, which will be described later, and also to prevent the spread of fire in the event of a fire.When wiring, it is removed by hitting it from above.

Reference numeral 2 denotes a wiring chisel, which is erected on the flanges 1 with the knock lid 10 in the center. The thickness of the wiring pipe 2 is determined by the thickness and number of electric wires, but a 39φ electric conduit can be used in many cases. The wiring chisel 2 is fixed to the flange 1 by welding. Note that the inner diameter of the wiring chisel blade 2 is naturally larger than the diameter of the dowel hole 1A. A threaded portion 2A is engraved on the upper outer circumferential surface of the o-beam 2 for wiring.

A coupling 6 is screwed onto the threaded portion 2A of the wiring chisel 2. The length of the coupling B and the height of the threaded portion 2A are equal to each other, and the height of the wiring tube 2 is determined in consideration of the length of the coupling B. coupling 3
When wiring, a light current outlet or a high current outlet is screwed on, and an insert cap is screwed on when wiring is not performed after the flange 1 is fixed to the formwork material.

This floor penetrating member for wiring is smaller, lighter, and cheaper than a floor box or 70-ar duct.

Penetration and placement of floor penetration members for wiring into the floor.

Do it as follows. First, a plurality of floor penetrating members for wiring are connected to the formwork material 4 at a pitch of, for example, 5 or In horizontally and 1 m vertically.
It is placed on top and fixed to the formwork material 4 with screws or the like using the fixing holes IBi. Next, screw the insert cap 5 onto the coupling B.

The height of the coupling B is adjusted to match the level of the upper surface anvil concrete 6 of the plurality of insert caps 5. Next, floor concrete 6 is poured, and floor tiles 7 are pasted on top of the floor concrete B. In this way, the wiring floor penetrating member penetrates through the floor concrete 6 except for the floor tiles 7 (see FIG. 2). In addition, insert cap 5
Marker 5A is screwed onto the top surface of the machine.

The placement location of a floor penetrating member for wiring which is raised to the same level as or below the level of the floor tile 7 and cannot be seen by the floor tile 7 is displayed.

Wiring to a telephone set, outlet, etc. is done as follows. First, a floor penetrating member for wiring is selected using the marker 5A, which is closest to a telephone set, an outlet, etc., and is located under a desk, etc., in a place that does not obstruct passage. Next, the necessary amount of the υ floor tile 7 is removed using a core drill or the like to expose the insert gap 5'ff. Next, the insert cap 5 is removed from the coupling 6, the knock lid 1C is tapped from the top, and the knock lid 1C is removed. Next, attach a light electrical outlet (not shown) or a strong electrical outlet 8 to the coupling B, and connect it to the concrete floor 6 at a certain distance from the ceiling provided under the concrete floor 6, that is, from the ceiling 9 of the lower floor. Pull up all the electric wires 10, wiring/ξ Eve 2. Coupling 6゜ Wire to a telephone set, outlet, etc. via the outlet for low power or the outlet for high power 8 (see Figure 3). A fireproof sealing material is sealed in the floor penetrating member.Wiring from the light electrical outlet or the heavy electrical outlet 8 to the telephone set, outlet, etc. is installed on the leg using the leg of a desk or the like.

The floor penetrating member for wiring according to the present invention is inexpensive;
Many can be penetrated and placed throughout the floor in short spans. Therefore, wiring to a telephone, an outlet, etc. can be run from a floor-penetrating member for wiring located at a location such as under a desk or the like where it does not obstruct passage, via a light-current outlet or a heavy-current outlet.

Therefore, this invention makes it possible to eliminate the installation of heavy current outlets, buried pipes, moldings, etc. for the 9 outlets for low power on the 9 passages.

As explained above, the present invention forms a knock lid that is removed from the top when wiring on a flange that is fixed to a formwork material, and a wiring pipe is erected on the flange with the knock lid as the center. When wiring, the outlet for light electric current or the out for heavy electric current is screwed on and the flange is fixed to the formwork material. By attaching the outlet to the spring, it is possible to eliminate the installation of a single outlet for low current or one outlet for high current over the spring, and the need for wiring using buried pipes, moldings, etc., which can be achieved.
