Description

[Detailed explanation of the device] This device is placed on the concrete base surface when pouring floor concrete, aligns the upper end with the reference line using mortar or wedges, and then fixes with nails as necessary. Pour concrete for the floor, bury the side walls in the concrete layer, and run pipes such as water pipes, gas pipes, steam pipes, and various electric wires such as electric light lines, telephone lines, and fire alarm lines inside. This invention relates to a concave groove-shaped piping duct whose top opening is covered with a lid that is flush with the floor.

Hereinafter, one embodiment will be described in detail with reference to the drawings. The piping duct 1 of this invention is composed of a side wall plate 2, a bottom plate 3, and a cover plate 4.

The side wall plate is made of hard synthetic resin or light metal, and its shape is as shown in FIG. A lid locking side 9 is formed in the bottom plate insertion groove 8, and a lid locking side 9 is provided at a position slightly below the upper end of the vertical plate to protrude in the same direction as the projecting sides 6 and 7, and is nailed to the left side of the lower end of the vertical plate 5. The side 10 is provided as necessary, and further,
An appropriate number of dovetail-like protrusions 11 are formed on the left side of the vertical plate 5 over the entire length in the longitudinal direction.

The bottom plate 3 is a narrow plate made of metal, plywood, or synthetic resin with a thickness matching the groove width of the bottom plate insertion groove 8, and the cover plate 4 is a narrow plate made of metal, plywood, or synthetic resin that matches the groove width of the bottom plate insertion groove 8. It is made of a metal plate, plywood, or synthetic resin plate with a thickness that matches the dimensions, and the width is approximately the same as the bottom plate 3.

In order to construct the piping duct 1 by assembling and combining the side wall plate 2, the bottom plate 3, and the cover plate 4, the two side wall plates 2, 2 are erected with the bottom plate insertion grooves 8 facing each other, and the Insert the bottom plate 3 into the bottom plate insertion grooves 8 and 8 of the side wall plates.
The lid plate 4 is placed between the lid locking sides 9, 9 of the side wall plates 2, 2.

Reference numeral 12 indicates an empty space for a piping duct.

The piping duct 1 constructed in this way is placed on a concrete base 13 during floor concrete pouring, and concrete 14 is poured around the piping duct 1 to form the floor surface.

At that time, since the concrete base surface is extremely uneven, mortar or wedges are placed at the bottom of the piping duct 1.
Adjust the upper end of the piping duct 1 so that it matches the floor finish surface correctly, and then tighten the nailing edge 10 as necessary.
It is fixed to the base concrete 13 with concrete nails (not shown).

Then, with the upper end of the piping duct 1 as a reference, the poured concrete for forming the floor surface is smoothed and leveled to make it flush, and then hardened.

The lid 4 of the piping duct 1 buried and fixed in the floor in this way is removed during piping, various pipes 15 are piped into the empty chamber 12, and then the lid 4 is put on again.

Reference numeral 16 indicates a flooring material bonded onto the 14th surface of the floor concrete.

The piping duct 1 of this invention is obtained by assembling and joining the side wall plate 2, the bottom plate 3, and the cover plate 4 as described above, so it can be easily assembled on site, and is therefore very convenient without being bulky during transportation. Not only that, but by changing the widths of the bottom plate 3 and the lid 4, the width of the piping duct itself can be adjusted.

In addition, when the side wall plate 2 is made of hard synthetic resin, it can not only be easily manufactured by extrusion molding, but also the dovetail-shaped protrusions 11 formed on the side wall plate can be embedded into the concrete and firmly fixed. Furthermore, if nailing edges 10 are provided as necessary, the piping duct can be easily fixed, and subsequent concrete pouring work can be performed easily.

In addition, by using this piping duct, not only will the various pipings not be exposed on the floor, but they will also be flush with the floor, making it easier to install flooring materials. I can do it.
