[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a black pointer used in a mortar finishing work on a wall surface or a floor surface during construction work, for example, in a process of performing finishing work such as so-called blacking out and finishing painting.

[0002]

2. Description of the Related Art Conventionally, in the painting work of a concrete wall surface, a floor surface, or the like, a blackout operation for displaying a horizontal black line or a vertical black line based on dimensions on the wall surface or the like has been performed in advance. When performing finishing work such as mortar painting, in order to leave the desired points (dimension reference points), leave the point part large with a so-called useless hole,
Or, they are performing another blackout operation.

[0003]

[Problems to be Solved by the Invention] When performing a finishing operation, it is troublesome and troublesome to leave a large useless hole as in the conventional example. In addition, when the final paint is applied to this useless hole, color unevenness may appear, there are problems such as poor finish and unsightly appearance, etc., and these points are problems to be solved. .

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a black pointer that can quickly and neatly transition from blackout to finishing work such as finish painting.

[0005]

As a means for solving the above problems, a black pointer according to the present invention is, as shown in the embodiment of the drawing, a plate 1 adhered to a wall surface 5 or the like.
And a point bar 2 protruding from the plate 1 and having a length capable of displaying a point. The point bar 2 is characterized in that a cuttable groove 2a is formed near the base end.

[0006]

Function The plate 1 is adhered to a point portion such as the wall surface 5 to be left for the next step such as the finish painting while matching the vertical ink x and the horizontal ink y (see FIG. 3). Since the point bar 2 protruding from the plate 1 indicates a desired point, there is no need to leave a useless hole. Upon completion of finishing work,
A groove 2a formed near the base end of the point rod 2
It is sufficient to cut at the position. The portion of the point bar 2 is extremely small, so that final surface treatment and the like can be performed neatly and simply.

[0007]

Next, an embodiment of the present invention shown in the drawings will be described. The ink pointer shown in FIG. 1 includes a plate 1 made of vinyl chloride and a point bar 2 also made of vinyl chloride. However, the material is not limited to the above. As shown in FIG. 3, the plate 1 is formed in a disk shape having a diameter of about 20 mm and a thickness of about 0.5 mm. Four notched portions 1a cut into a triangular shape are formed at intervals of 90 degrees. This is to ensure that the points can be determined in accordance with the horizontal black line x and the vertical black line y. A double-sided tape 4 that can be adhered to the wall surface 5 and the like is attached to the back surface of the plate 1 (however, a bond or the like may be used instead of the double-sided tape 4).

The point bar 2 is formed as a bar having a length of about 35 to 50 mm and a diameter of about 3 mm so that points can be displayed. In the vicinity of the base end of the point bar 2 close to the plate 1, a groove 2a capable of cutting the point bar 2 is formed. The point bar 2 is protrudingly provided at a substantially central position of the disk-shaped plate 1.
In order to reinforce the state of attachment of the point bar 2 to the plate 1, a triangular rib 3 extending over both the base end of the point bar 2 that does not cover the position of the groove 2 a and the plate 1 is formed of the plate 1. It is provided (or molded) on the same diameter line as the cutout portion 1a.

Next, a method of using the black pointer will be described. The plate 1 is attached to the wall 5 or the like with the double-sided tape 4 so that the diameter line portions of the notches 1a... Of the plate 1 overlap with the points where the horizontal black line x and the vertical black line y intersect on the wall 5 (see FIG. 3). Adhere (FIG. 1). In addition, at the time of this point collection, if the horizontal black line x and the vertical black line y are indicated by different colors, the plate 1 can be easily bonded. As shown in FIG. 1, the point bar 2 is configured to have a length capable of displaying a point (longer than the mortar coating thickness 6).
The troublesome work of painting such as leaving a useless hole is unnecessary. The next work such as mortar finish painting and urethane foam spraying can be performed quickly and neatly. After the coating operation is completed, when the coating material is appropriately hardened, the point bar 2 is cut and removed at the position of the groove 2a by an operation such as bending. As a result, only a small hole having a diameter substantially equivalent to that of the point bar 2 remains, so that final finishing such as closing the hole can be performed simply and neatly (FIG. 2).

[0010]

[Effects of the present invention] The black pointer according to the present invention
The points required for a series of work processes from the blacking out to the finishing work such as finish painting can be completed quickly, easily and completely, and the workability is excellent. In addition, since the finishing operation can be performed without leaving a useless hole or the like, an architectural structure with a beautiful appearance can be provided.
