Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a usage indicator for a heat insulating wall insert used in a wall using a heat insulating material (insulating wall).

(Prior Art) Many types of inserts are used depending on the purpose, such as for building equipment, air conditioning equipment, or electrical equipment. The inserts buried in the insulating walls are used for subsequent installation work according to the above-mentioned use.

(Problems to be solved by the invention) However, the heat insulating material used as the heat insulating wall is available in many different thicknesses depending on the region where it is used. For this reason, when thick heat insulating material is used, the lower end of the insert 10 is located at the back as shown in Figure 11, making it difficult to see. There was a problem that it was difficult to distinguish between the two, making subsequent facility construction difficult.

The present invention was developed in view of these circumstances, and even if the thickness of the insulation material is different, the display part is exposed on the ceiling surface, and the insert buried in the insulation wall is used for building equipment. The purpose of the present invention is to provide an indicator that allows one to confirm at a glance whether the device is for air conditioning equipment or electrical equipment.

(Means for Solving the Problems) In other words, the use indicator for the heat insulating wall insert according to the present invention is a cylindrical display indicating the use of the heat insulating wall insert on the ceiling surface after removing the concrete formwork. The tool includes a through hole through which a hanging bolt passes through the cylindrical body, a fitting portion that fits into a hanging bolt insertion hole of a heat insulating wall insert provided above the cylinder, and a fitting portion provided below. The apparatus is characterized by comprising a display part, and a connecting structure in which the upper part of the cylindrical body is connected to the lower part of the cylindrical body so that the cylindrical bodies can be interconnected.

(Function) In the case of such a usage indicator, by connecting multiple cylinders, the length can be changed according to the thickness of the insulating wall. can be exposed on the ceiling.

(Example) Hereinafter, the present invention will be explained according to an example shown in the drawings.

1 to 5, the display device 1 is formed into a cylindrical body having a through hole 4 through which a hanging bolt 18 (see FIG. 8) passes. The cylinder here is not limited to the cylindrical shape shown in the figure, but includes various shapes,
In short, it is sufficient if the suspension bolt 18 can be inserted into the cylinder.

The upper part of the display device 1 is formed into a cylindrical shape having a smaller outer diameter than the lower part, and as shown in FIG. ing. As shown in Figure 4, there is a step 3 between the upper and lower parts of the display device.
is formed so that the lower end of the insert 10 abuts this step 3.

Further, the lower part of the display 1 is formed into a cylindrical shape like the upper part, and constitutes the display part of the display 1. As will be described later, the display section is constructed by inserting the display device 1 into the insert 10.
The insert is installed in the insulation wall and is exposed on the ceiling after the concrete formwork is removed.

Such indications for each purpose of the display device 1 can be made, for example, by applying various colors to the cylindrical body depending on the purpose, by attaching codes such as letters, marks, symbols, etc. to the display part, or by adding colors, codes, etc. This can be realized by pasting a tearable piece of paper or the like with the markings on it on the two sides of the opening at the lower end of the display device 1.

As shown in FIG. 3, the outer diameter of the upper part of the display device 1, which is the fitting part, is formed to be approximately the same as the inner diameter of the lower part of the display device 1, so that it can also be fitted into the lower end opening 2 of the display device 1. It's summery. With this configuration, a plurality of display devices 1 can be connected in succession as shown in FIG. 4.

Next, how to use this indicator 1 will be described. First, as shown in FIG. 6, a pilot hole 15 is made in the heat insulating material 16 to which the insert 10 is fixed using a hole punching tool such as a punch. Next, the required number of indicators 1 are inserted into the insert 10 according to the thickness of the heat insulating material 16.
Connect to.

When connecting multiple indicators 1 in succession, fit the upper part of the indicator 1 into the hanging bolt insertion hole 11 of the insert 10, and then fit the upper part of the next indicator 1 into the lower end opening 2 of the indicator 1. This can be done easily by learning how to do it. This results in different thicknesses of insulation material 1
6, if the number of indicators 1 to be connected is determined, the length of the insert 10 can be easily changed according to the thickness of the heat insulating material 16.

In this case, instead of bringing the bottom end of one display device 1 into contact with the step 3 of the other display device 1 as shown in FIG. By changing the depth of the downwardly inserted portion of 1, finer length adjustment is possible.

In this way, the indicator 1 is connected to the insert 10 so that the length from the lower end of the indicator 1 to the seat 12 of the insert 10 matches the length of the pilot hole 15 of the heat insulator 16, and as shown in FIG. As shown, indicator 1
Insert the insert 10 connected to the prepared hole 15 into the prepared hole 15.

In the case of the insert 10 shown in the figure, a spiral protrusion is provided on the lower outer periphery of the insert 10 to be inserted into the heat insulating material 16.
The insert 10 is secured to the insulation 16 by screwing the lower portion into the insulation 16.

After fixing the insert 10 to the insulation material 16,
As shown in FIG. 8, concrete is poured and the formwork 17 is removed after the concrete has cured. The lower end of the display device 1 after removing the formwork 17 is located almost on the surface of the heat insulating wall, is clearly visible from the outside, and the display device 1 can be easily confirmed. After this, the suspending bolt 18 is attached to the insert 10.

The insert 10 is not only screwed into the heat insulating material 16 as shown in FIGS.
The seat 12a may be fixed to the heat insulating material 16 by nailing, and the main body 10a of the insert 10 may be inserted into this.

(Effect of the invention) As described above, the usage indicator for the heat insulating wall insert according to the invention has a connecting structure in which the upper part of the cylinder is connected to the lower part of the cylinder, and the cylinders can be interconnected. Therefore, depending on the thickness of the insulation wall, we connect the cylinders and change the length, and after removing the concrete formwork,
The display part can be exposed on the ceiling surface, which allows you to determine whether the insert buried in the insulation wall is for building equipment, air conditioning equipment, or electrical equipment. You can check it at a glance. Therefore, subsequent facility construction can be carried out efficiently and work efficiency can be improved.

Also, according to the usage indicator according to the present invention, the 10th
As shown in the figure, for inserts in which the main body and the seat are separate, the length of the insert can be adjusted and the height of the main body protruding above the heat insulating material can be made the same by using a usage indicator. Therefore, the amount of the insert buried in the concrete wall can be made constant. Therefore, the tensile strength for each insert can be kept constant without varying, and safety can be ensured.

Furthermore, by using the usage indicator according to the present invention, it also serves as a guide when inserting the insert into the heat insulating wall, making it easier to insert the insert into the heat insulating wall. Furthermore, it protects the pilot hole in the insulation material and prevents the tip of the suspension bolt from damaging the pilot hole in the insulation material when installing the suspension bolt, while also ensuring that the tip of the suspension bolt is guided into the suspension bolt insertion hole of the insert. can. Furthermore, when inserting the insert into the insulation material, the indicator on the cylinder is inserted into the entire length of the insulation material, so even if the head of the insert on the insulation material is subjected to an external force, for example from the side, the insert will not move. Do not collapse.
