Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display plate for piping and a method for forming a through hole for piping.

[0002]

2. Description of the Related Art In a steel-framed hospital building, a fireproof partition wall down to a slab is to be installed between a corridor and a patient room, and in every three patient rooms between patient rooms. As shown in FIG. 4, since this fireproof partition wall 13 is installed under the slab, that is, up to the ceiling 14, a hole-piercing work for arranging equipment piping, wiring, ducts, etc. has been performed for each job type. .

[0003]

However, since the work of opening the through-hole is carried out for each job, there are the following problems. (1) Each worker does not know what kind of piping, wiring or ducts are arranged nearby. (2) Since the construction order is different, if the lower piping is constructed first, the upper piping work becomes difficult. (3) It takes time to mark out. (4) There is a lot of stepladder work, which is dangerous. (5) Forgotten construction cannot be grasped at a glance. (6) It takes time to check the pipe level.

The present invention has been made in view of these problems, and an object thereof is to provide a display plate for pipes and a pipe penetration for pipes in which a through hole can be easily and safely installed in a partition wall for fire protection in the ceiling. It is to provide a method for forming holes.

[0005]

The gist of a display plate for piping for solving the above problems is characterized in that the outer shape of the pipe for piping and the pipe name are described on the surface of the display plate. It also includes that the core of the tube is described in the center of the outer shape of the tube. Further, it includes that the reference line for installation is described on the surface of the display plate.

Further, the gist of the method of forming the through hole for piping is that the outer shape of the pipe for piping and the outer shape of the pipe after the display plate on which the pipe name is described are pasted at the place where the through hole for piping is provided. It is characterized in that a through hole for piping is formed according to the name of the piping. The location where the through hole for piping is provided includes the partition wall for fire protection in the ceiling. In addition, the center of the outer shape of the pipe for piping includes the description of the pipe core.

Each worker can grasp what kind of pipes, wirings or ducts are arranged nearby.
The construction order can be easily grasped, and work can be performed in an efficient order. It is possible to reduce stepping work by eliminating the need for marking. You can grasp the forgetting of construction at a glance. You can easily check the level of piping. Work to fill the gap between the pipe and the through hole can be done at once. Allows highly accurate drilling work centered on the pipe core. The reference line for installation allows the display plate for piping to be accurately attached to the partition wall for fire protection. By simply attaching the pipe display plate to the fireproof partition wall, the through holes can be installed easily, safely and accurately according to the pipe outline and pipe name.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a display plate for piping and a method for forming a through hole for piping according to the present invention will be described below with reference to the drawings. First, an embodiment of a display plate for piping will be described, and then an embodiment of a method of forming a through hole for piping will be described. In the respective embodiments, the same configurations will be described with the same reference numerals, and different configurations will be described with different reference numerals.

As shown in FIG. 1, the display plate 1 for piping has a rectangular display plate 2 formed of a transparent resin film sheet or a thin iron plate, and the outer surface 3 of the pipe for piping, the pipe core 4, and the like. The pipe name 5 is described, and the installation reference lines 6 are vertically described on both end sides. The installation reference line 6 is for accurately installing the pipe display plate 1 in accordance with the return core marked on the fireproof partition wall. Mounting screws (not shown) are provided at the four corners of the display plate 2, and an adhesive or an adhesive tape that replaces the mounting screws is provided on the back surface. The display plate 2 may be formed of a transparent or translucent plastic plate other than cloth or paper.

Next, a method of forming a piping through hole using the piping display plate 1 will be described. This piping display plate 1 is to be attached to a fireproof partition wall 8 in the ceiling ceiling 7 to form various kinds of through holes for piping therein. First, all fireproof partition walls having through holes for piping are provided. The return core 9 for installing the display plate 1 for piping is marked on 8 at a position 1 m from the core 10.

Next, the return line 9 is aligned with the installation reference line 6 and the piping display plate 1 is attached to the fireproof partition wall 8 with a mounting screw or an adhesive. By aligning the installation reference line 6 with the return core 9, the formation position of the through hole for piping can be accurately obtained. That is, since the outer shape 3 of the pipe can be marked out at the same time as the display plate 1 for piping is attached, the positions where the through holes are formed in the continuous fire protection partition wall 8 can be accurately aligned.

Next, all the pipe through holes 11 are formed along the outer shape 3 of the pipe described on the pipe display plate 1. This perforation can be done by one person at a time, which is very efficient work.

Next, after completion of this drilling work, the pipe name 5 written on the upper or lower part of the pipe through hole 11
According to the above, predetermined piping (or wiring) 12 and the like are performed. Since the pipe 12 according to the pipe name 5 as described above is formed, efficient work can be performed in order from the upper side to the lower side.

Next, after the above-mentioned piping work is completed, the level adjustment work of the pipe is performed, the work of filling the gap between the pipe and the through hole (not shown) is performed, and the pipe work is completed. Since the work of filling this gap can be performed simultaneously for each pipe, it is a very efficient work.

[0015]

EFFECTS OF THE INVENTION Each worker can grasp what kind of pipe, wiring or duct is arranged nearby.

The construction order can be easily grasped, and work can be performed in an efficient order.

The step of stepping can be reduced by eliminating the need for marking.

It is possible to understand at a glance if the construction is forgotten.

It is possible to easily check the level of piping.

Since the work of filling the gap between the pipe and the through hole can be performed at one time, the work is efficient.

It is possible to perform highly accurate drilling work centered on the pipe core.

The pipe display plate can be accurately attached to the fireproof partition wall by the installation reference line.

By simply attaching the piping display plate to the fireproof partition wall, the through holes can be easily and safely installed with high accuracy according to the outer shape of the tube and the piping name.
