Abstract

(57) [Summary] [Purpose] To provide a black pointer used in the process of finishing work such as so-called marking to finish painting in mortar finishing work on walls and floors during construction work. [Structure] A plate 1 adhered to a wall surface 5 and the like, and a point rod 2 projecting from the plate 1 and having a length capable of displaying points. The point rod 2 has a severable groove 2a. It is formed near the part. [Effect] The points required for a series of work processes, from marking out to finishing, such as finish painting, can be completed quickly, easily, and with excellent workability. Since finishing work can be done without leaving useless holes, it is possible to provide a building structure that is beautiful in appearance.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a black ink pointer used in the process of performing finishing work such as so-called ink drawing to finish painting in mortar finishing work on a wall surface or floor surface during construction work.

[0002]

[Prior Art]

 In the past, in painting work on concrete wall surfaces or floor surfaces, stakeout work has been carried out in which dimensional-based horizontal and vertical black lines are previously displayed on the wall surfaces and the like. In the subsequent finishing work such as mortar painting, in order to leave the desired point (dimension reference point), either purposely leave the point portion large with a so-called dead hole, or perform the reding operation again. There is.

[0003]

[Problems to be solved by the present invention]

 When performing the finishing work, the work of leaving a large blind hole as in the above-mentioned conventional example is troublesome and troublesome. In addition, when the final coating is applied to the useless holes, color irregularity may appear, resulting in poor finish and unsightly appearance, and these points are problems to be solved. .

Therefore, an object of the present invention is to provide a black ink pointer that can be quickly and cleanly transferred from blackening to finishing work such as finish painting.

[0005]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems, the black pointer according to the present invention is, as shown in the embodiment shown in the drawings, a plate 1 to be adhered to a wall surface 5 and the like, and a long point displayable projecting point on the plate 1. It is characterized by comprising a point rod 2 of a sword and a cuttable groove 2a formed in the point rod 2 near the base end.

[0006]

[Action]

 The plate 1 is attached to the point portion of the wall surface 5 or the like that is desired to be left for the next process such as finish painting, while aligning the vertical ink x and the horizontal ink y (see FIG. 3). Since the point bar 2 protruding from the plate 1 displays the desired point, it is not necessary to leave a dead hole. When the finishing operation is completed, the point rod 2 may be cut at the position of the groove 2a formed near the base end portion thereof. The portion of the point rod 2 is extremely small, and the final surface treatment can be performed neatly and easily.

[0007]

【Example】

 Next, an embodiment of the present invention shown in the drawings will be described. The black pointer shown in FIG. 1 is composed of a plate 1 made of vinyl chloride and a point rod 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 plate thickness of about 0.5 mm, and the outer peripheral portion thereof has a small diameter line portion in the diameter line direction. The cutouts 1a, which are left in the shape of a triangle, are formed at four 90-degree intervals. 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 or 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 rod 2 has a length of about 35 to 50 mm and a diameter of about 3 mm so that the point can be displayed. A groove 2a capable of cutting the point rod 2 is formed near the base end portion of the point rod 2 close to the plate 1. The point rod 2 is provided so as to project at a substantially central position of the disc-shaped plate 1. In addition, in order to reinforce the attachment state of the point rod 2 to the plate 1, a triangular rib 3 extending over both the base end portion and the plate 1 which does not extend to the position of the groove 2a of the point rod 2 is provided on the plate 1. It is provided (or molded) in the same arrangement on the diameter line as the notch 1a.

Next, a method of using the black pointer will be described. The plate 1 is attached to the wall surface 5 or the like with the double-sided tape so that the diameter line portion of each notch 1a of the plate 1 overlaps the point where the horizontal ink stroke x and the vertical ink stroke y of the wall surface 5 intersect. Adhere by 4 (Fig. 1). It should be noted that, when the points are taken, if the horizontal ink stroke x and the vertical ink stroke y are shown in different colors, the plate 1 can be easily bonded. As shown in FIG. 1, the point bar 2 is configured to have a point displayable length (longer than the mortar coating thickness 6), and troublesome work such as painting with a blind hole is unnecessary. The next work such as finish coating of mortar and spraying of urethane foam can be done quickly and cleanly. After the coating work is completed, when the coating is appropriately hardened, the point rod 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 of approximately the same diameter as the point rod 2 remains, so that the final finishing such as closing the hole can be done easily and neatly (Fig. 2).

[Effects of the present invention]

 The black pointer according to the present invention is capable of quickly, simply and completely performing point acquisition required for a series of work processes from marking out to finishing work such as finish painting, and is excellent in workability. Moreover, since finishing work can be performed without leaving useless holes, it is possible to provide a building structure that is beautiful in appearance.
