[Industrial applications]

 In order to prevent dew condensation and to provide a heat insulation effect, the present invention is designed to form a standard black ink such as vertical black ink or horizontal black ink on the wall surface of a building on which a urethane foam layer has been formed by spraying urethane. It relates to a reference black display block to be displayed after the urethane layer is formed.

[0002]

[Prior art]

 Fig. 4 is a cross-sectional view of the wall part of a general building. As shown in the figure, the wall surface of the building wall 1 on the indoor side is provided on site to prevent condensation and heat insulation. Urethane was sprayed with a gun to form a foamed urethane layer 2, a gypsum board 3 was attached thereon, and a cloth 4 or the like was attached onto the gypsum board 3 to form an inner wall. In the figure, 16 is a cement-based adhesive for attaching the gypsum board 3 to the urethane foam layer 2.

FIG. 5 is a perspective view showing a state before the urethane is sprayed on the indoor side wall surface of the wall body 1 shown in FIG. 4, and the indoor side wall surface of the wall body 1 has a number of vertical and horizontal references. Ink 5 is stamped out and entered.

Therefore, when urethane is sprayed on the wall surface of the wall body 1 on the indoor side, the reference black ink 5 marked on the wall surface is covered with the urethane foam layer 2 and becomes invisible. Therefore, conventionally, the gum tape balls 6 formed by rolling the gum tape are attached to at least two places on the reference black ink 5. FIG. 6 is a cross-sectional view showing, in order, how to use the gum tape ball 6 shown in FIG.

As shown in (A) in the figure, this gum tape ball 6 is pasted on the reference black ink 5, and then, as shown in (B), a predetermined thickness is applied to the wall surface of the wall body 1 on the indoor side. The urethane foam is sprayed to form the urethane foam layer 2. Next, as shown in (C), when the gum tape balls 6 are removed from the urethane foam layer 2, the reference black ink 5 appears at the bottom of the space 7 formed after that. Is marked on the surface of the urethane foam layer 2, and the parts and members are mounted and their positions are checked with reference to the reference black ink 5. The gypsum board 3 is mounted on the surface of the urethane foam layer 2, and The inner wall was formed by attaching cloth 4 etc. on top.

At this time, before attaching the gypsum board 3 to the surface of the urethane foam layer 2, as shown in (D), urethane is sprayed into the space 7 formed after the gum tape ball 6 is removed, It was necessary to fill the entire space 7.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional construction method, in order to save the trouble, the space 7 formed after the gum tape ball 6 is extracted is not sprayed with urethane, but the gypsum board 3 is directly attached and the cloth 4 or the like is attached to the inner wall. In some cases, dew condensation may occur on the inner wall of the portion where the space 7 remains, and uneven heat insulation of the inner wall may occur, which is not preferable for construction. Also, since the size of the gum tape balls 6 is not uniform, if the urethane is sprayed using the gum tape balls 6 as a guide, the thickness of the foam urethane layer 2 will not be uniform, so use a drill or awl. Therefore, the thickness of the urethane foam layer 2 needs to be checked in places to check the thickness, which is very troublesome and damages the urethane foam layer 2, which is not very preferable.

It should be noted that the work of filling the space 7 by blowing urethane into the space 7 formed after removing the gum tape balls 6 was extremely troublesome and was a cause of delay in the work process.

The present invention has been proposed in view of the above-mentioned circumstances, and it is not necessary to remove it like a conventional gum tape ball, and it is possible to reliably display the position of the reference black ink as it is attached. The purpose of the present invention is to provide a block for displaying a standard black ink, which is capable of forming a urethane foam layer uniformly using this as a guide and is extremely convenient in practice.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms an integrated block by bonding foam insulation materials of the same shape having different thicknesses and having a predetermined thickness with their vertical joint surfaces in contact with each other. The feature is that an adhesive surface is provided on the bottom surface of the block to form a reference black display block.

[0011]

[Action]

 Since the reference black display block of the present invention is constructed by the means as described above, the adhered vertical joint surface can be clearly identified from the difference in color. Therefore, check the position so that this vertical joint surface matches the reference black ink written on the wall surface, and if you attach it to the wall surface through the adhesive surface provided on the bottom surface of the block, spray urethane in this state. Even if the reference black ink written on the wall is covered, the position of the reference black ink can be known from the position of the vertical joint surface appearing on the surface of this block.

Therefore, by connecting the positions of the vertical joint surfaces appearing on the surfaces of the blocks at two places, the reference black ink can be accurately written again on the formed urethane foam layer. Further, since this block has a predetermined thickness, the thickness of the urethane foam layer can be made uniform by using the thickness of this block as a guide.

If the surface of the block is covered with the sprayed urethane, it will be scraped off. At this time, even if the surface of the block is scraped off a little, the position of the vertical joint surface will differ due to the difference in color. Since it can be clearly identified, the position of the reference black can be accurately indicated in any case.

【Example】

 Hereinafter, the invention will be specifically described based on Examples. FIG. 1 is a perspective view of a reference black display block showing an embodiment of the present invention.

In the figure, 8 and 9 are foam heat insulating materials having a predetermined thickness H and having the same shape but different colors, and their vertical joint surfaces 10 are brought into contact with each other and bonded to each other to form an integrated block 11. Are formed. Reference numeral 12 denotes an adhesive surface provided on the bottom surface of the block 11, which is used after peeling off the surface seal 13.

The reference black display block 14 of the present invention having the above-mentioned configuration is used in place of the conventional gum tape ball 6. FIG. 2 is a perspective view showing a state before the urethane is sprayed on the wall surface on the indoor side of the wall body 1. Since the reference black ink 5 is written on the wall surface on the indoor side of the wall body 1, a small amount of ink on the reference black ink is shown. The reference black display blocks 14 of the present invention may be attached to two locations at least.

FIG. 3 is a cross-sectional view showing in sequence the method of using the reference black display block 14 shown in FIG. As shown by (A) in the figure, the reference black display block 14 is attached onto the reference black 5, and the block 11 has a predetermined thickness H and has the same shape of foam insulation having different colors. Since the materials 8 and 9 are bonded to each other with the vertical bonding surface 10 in contact with each other, the bonded vertical bonding surface 10 can be clearly identified from the difference in color. The position may be confirmed so that 10 corresponds to the reference black ink 5 written on the wall surface, and the block 10 may be attached to the wall surface via the adhesive surface 12 provided on the bottom surface of the block 11.

Next, as shown in (B), urethane is sprayed on the inner wall surface of the wall body 1 by a predetermined thickness to form the urethane foam layer 2. At this time, the thickness H of the reference black display block 14 is set in advance to a predetermined thickness H corresponding to the thickness of the urethane foam layer 2 to be formed. By spraying urethane with 14 as a guide, the urethane foam layer can be formed to have a uniform thickness.

Note that the urethane coating 15 may cover the display of the reference display block 14 with the urethane coating 15. In that case, the surface of the block 11 should be slightly scraped off as shown in (C). However, since the position of the vertical joint surface 10 can be clearly identified due to the difference in color, the position of the reference black ink 5 can be accurately known from the position of the vertical joint surface 10 1 in any case.

Therefore, by connecting the positions of the vertical joint surfaces 10 represented on the surfaces of the blocks 11 at the two locations, the reference black ink 5 can be accurately written again on the formed urethane foam layer 2. You can In the present embodiment, the foam heat insulating materials 8 and 9 having the predetermined thickness H and different colors from each other were made into a rectangular parallelepiped having the same shape. It may be a block of the body.

Further, in this embodiment, two foam heat insulating materials are bonded to each other to form an integral type block. However, for example, four foam heat insulating materials are bonded to each other to form an integral type block. It is also possible to display a vertical joining surface that intersects at a right angle due to the difference in the above, and to make this correspond to the intersection of the reference black ink that intersects at a right angle.
