Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a spraying reference board used for spraying urethane foam.

[Conventional technology]

Conventionally, when building a steel-framed or concrete-made building in cold regions such as Hokkaido and the Tohoku region, in order to prevent dew condensation and to insulate heat, the urethane foam has a constant thickness (10 mm It is known to be blown to about 40 mm).

As an example thereof, there is a method of spraying urethane foam shown in FIGS. 6 to 8.

In the conventional example in which this urethane foam is sprayed, as shown in FIG. 6, land ink 20 or core ink 22 is printed on the inner surface of the wall 10, ground ink 21 or the like is printed on the floor 14, and the sash 11 or the like is attached to the urethane foam.
After 12 was sprayed, it was confirmed by spraying with a nail or a needle whether it was sprayed according to the specified thickness. If it was thin, it was sprayed further, and if it was thick, the thick part was scraped off. Further, in order to prevent the black ink from disappearing, there are provided unblown portions 15 which are left unblanked in some places as shown in FIG.

After the urethane foam is sprayed, the surface of the urethane foam 12 sprayed as shown in FIG. 7 is again blacked out using the black ink in the unblown portion 15 as a reference, and then the unblanked portion 15 is sprayed. The spraying of urethane foam 12 has been completed.

Also, as another conventional example, by spraying urethane foam,
In order to make it easier to obtain a fixed thickness of the urethane foam 12, the small pillar 40 is attached to the wall 10 as shown in FIGS. 9 and 10, and the blowing surface 13 is located so as to come to the tip of the small pillar 40.
There are 12 ways to spray.

Further, as another embodiment, as shown in FIG. 11, a pier 42 having the same thickness as the sprayed thickness of the urethane foam 12 is fixed.
There is also a method of spraying the urethane foam 12 so that it is attached to the wall 10 at a pitch of about 2 m and the thickness of the pier 42 is obtained.

[Problems to be solved by the device]

However, in the conventional example shown in FIGS. 6 to 8,
When the black ink is transferred, the black ink of the unblown part 15 that serves as a reference is drawn on the wall surface, and the thickness of the urethane foam 12 interferes with the accuracy of the black ink. In addition, the survey instrument and two workers Is required, and re-spraying is considerably troublesome and costly. Also, the thickness of the urethane foam 12 sprayed must be measured separately.

Another conventional example shown in FIGS. 9 and 10 is urethane foam.
There is a drawback in that the small pillar 40 cannot be seen during the spraying of 12 and the thickness of the urethane foam 12 to be sprayed is unknown. In addition, marking out after blowing the urethane foam 12 must be considered separately.

In another conventional example shown in FIG. 11, it takes a lot of time to attach and detach the pier 42, and after removing the pier 42, the portion where the middle pier 42 was attached is blasted, so that the blasting labor is doubled. . Also, with this means, marking out after spraying the urethane foam 12 must be considered separately.

There is currently no way to finish the spraying work without transferring the black ink.

SUMMARY OF THE INVENTION The present invention has been made in view of the above matters, and it is a technical subject to easily obtain a uniform spray thickness of urethane foam and to easily transfer black ink.

[Means for solving the problem]

The present invention has the following configuration in order to solve the above technical problems.

That is, there is an inclined surface 2 around the upper surface 1, and the inclined surface 2
Is connected to a lower surface 3 having an area larger than that of the upper surface 1 to form a board main body 50, and the board main body 50 is formed.
The lower surface 3 of 50 is provided with a double-sided adhesive tape 4,
A reference line 5 was provided on the upper surface 1 and the inclined surface 2 to form a urethane foam spray reference board.

[Action]

According to the present invention, the core ink 22 and the land ink 20 on the inner surface of the wall 10 are respectively prepared after the preparation of the urethane spraying such as the ground treatment on the inner surface of the wall 10 and the marking out of the ground ink 21, the core ink 22 and the land ink 20. The reference line 5 of the board body 50 is aligned with the black ink at the predetermined position, and the board body 50 is attached to the inner surface of the wall 10 with the double-sided adhesive tape 4. Then, the foamed urethane 12 is sprayed on the entire surface of the wall 10 using the fixed thickness of the board body 50 as a guide to form a layer of the foamed urethane 12 having the same thickness as the board body 50.

When the urethane foam 12 is sprayed around the board body 50, the board body can be sprayed from any direction.
Since there is an inclined surface 2 around the upper surface 1 of the 50, there is no hidden portion, so there is no unsprayed portion.

Next, urethane foam attached to the upper surface 1 of the board body 50.
Scrap off 12 and check the spray thickness of urethane foam 12 using a plaster ruler or water thread, re-spray the thin part, and scrape off the thick part. And the board body
By connecting the reference line 5 of 50 and the reference line 5 of another board body 50 on the straight line of the reference line 5, urethane foam 12
The surface of the layer can be marked.

〔Example〕

Hereinafter, one embodiment according to the present invention will be described with reference to FIGS.
Description will be made with reference to the drawings.

In this embodiment, an inclined surface 2 is provided around an upper surface 1, and the inclined surface 2 is connected to a lower surface 3 having an area larger than that of the upper surface 1 to form a square pyramid pyramid made of urethane foam. The board body 50 is formed into a shape. This board body
The lower surface 3 of 50 is provided with a double-sided adhesive tape 4,
A return dimension from a reference point may be written on the upper surface 1 and a gum tape 6 may be attached to protect the written dimension.

A straight line cut is made in the central portion of the upper surface 1 and the inclined surfaces 2, 2 on both sides of the upper surface 1 to provide a reference line 5. Further, the reference line 5 has a structure in which a portion left by cutting by 3 mm to 4 mm is left near the lower surface 3.

When using this urethane urethane spraying reference board, as described in the section of the above action, the black ink 22 and the land ink 20 on the inner surface of the wall 10 have their respective black inks at predetermined positions.
Align the 50 reference lines 5 and attach.

[Effect of device]

The present invention is a urethane foam sprayed while looking at the upper surface 1 of the board body 50 when the urethane foam 12 is sprayed.
Since you can know the thickness of 12 layers, urethane foam 12
It is possible to obtain a constant spray thickness without excess or deficiency of the layer thickness.

Moreover, when the urethane foam 12 is sprayed around the board body 50, the board body 50 can be sprayed from any direction.
Since the inclined surface 2 is provided on the inner surface, a hidden portion of a portion that cannot be sprayed does not occur, so that the purpose of heat insulation and dew condensation prevention can be sufficiently fulfilled.

Then, the reference line 5 is formed on the upper surface 1 and the inclined surface 2 of the board body 50.
Since the board body 50 is attached to the inner surface of the wall 10, the black line is aligned with the reference line 5 provided on the inclined surface 2, and after the urethane foam 12 is sprayed, the board body is
Marking can be performed with the reference line 5 on the upper surface 1 of 50, and even one person can easily perform accurate marking. Moreover,
It is not necessary to spray the urethane foam 12 in two steps by providing the unblown portion 15, and the spraying can be performed at one time, which shortens the construction period.
