Abstract

PROBLEM TO BE SOLVED: To improve painting work efficiency by forming a recessed part with a height in a specific range at the tip of a paint uniforming piece provided at a right angle to both ends of painting width position regulating plates, along the width, and inclining the painting width position regulating plates upward by a required angle from the tip edge of the paint uniforming piece. SOLUTION: A recessed part 3 of 0.1-0.7mm in height is formed at the tip of a paint uniforming piece 1 of a paint applicator so as to form a slight clearance between the paint uniforming piece 1 and the panel surface at the time of bringing the paint uniforming face of the paint applicator into contact with the panel surface. Painting width position regulating plates 2 are provided at a right angle to both edges of the paint uniforming piece so as to be inclined when the paint applicator comes in contact with the panel surface. Paint is previously applied to the panel surface roughtly in narrower width than the final desired painting width, and the paint can be applied uniformly in the specified width only by moving the paint applicator on the paint in such a way as to drag it.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating tool for a concrete-based panel for coating the surface of a concrete-based panel with a coating material in a strip shape.

[0002]

2. Description of the Related Art In painting a concrete panel surface, it is often necessary to partially paint the entire panel surface in addition to painting a large area. A special automatic painting machine is used to paint the entire panel surface, but when painting parts where it is difficult to paint the whole surface or when painting partially on site construction, do not use an automatic painting machine etc. The need often arises. In this case, it is general to apply the paint directly to the panel surface with a brush or to apply or attach the paint once and apply it evenly using a brush or a plate-like spatula.

[0003]

However, since the surface of the concrete panel is generally rough, it is difficult to apply it evenly even with a brush. Among them, the surface of the lightweight cellular concrete panel is not only rough, but also has a large number of deep holes of various sizes due to air bubbles. Therefore, there is a problem that a recess is formed in the hole portion after coating and the coating is not performed uniformly.

On the other hand, if the roughly applied paint is leveled with a plate-like spatula, the drawbacks of the brush can be eliminated, but the paint spreads from the edge of the plate-like spatula and keeps a constant width to form a long strip. Can not be painted on. Therefore, a method of using other members such as a ruler or covering other than the coated surface with paper or the like in advance is also performed, but it is inefficient because it takes time to stick the paper or the like. Further, since the tip of the plate-like spatula is horizontal and is flush with the surface to be painted, it is difficult for a person skilled in the art to paint it to a certain thickness because the paint is scraped off.

Therefore, an object of the present invention is to easily and efficiently apply a paint evenly and without requiring skill when applying a paint to a concrete panel surface such as lightweight cellular concrete in a strip shape having a predetermined width. It is to provide a paint tool for concrete-based panels that enables good painting.

[0006]

According to the present invention for achieving the above object, a paint is roughly applied in advance in a thin strip shape on the surface of a concrete-based panel P, and the paint is evenly applied to a predetermined width and applied in a strip shape. A paint tool for a concrete panel, comprising a plate-shaped paint leveling piece 1 having a predetermined width and a paint width position regulating plate 2 provided at right angles on both edges thereof.
Has a concave portion 3 having a height of 0.1 to 0.7 mm along its width, and the coating width position regulating plate 2 is inclined upward from the leading edge of the paint leveling piece 1 by a required angle. It is a paint tool for concrete-based panels.

The coating tool for concrete panel of the present invention (hereinafter referred to as coating tool) operates as follows. First,
Since the paint leveling piece is provided with a recess having a predetermined depth of 0.1 to 0.7 mm, the paint is evenly applied and evenly applied to a constant thickness. Moreover, since the gap between the surface of the panel and the surface of the panel is smaller than 0.7 mm, the coating material is pushed into the holes on the surface of the panel when the coating material is leveled, and the entire coating material is embedded in the openings. As a result, it is possible to prevent a coating recess from being formed in the hole portion on the panel surface after coating.

Further, the coating width position regulating plate collects the paint which is about to overflow from both sides of the coating leveling piece and returns it to the coating leveling side again, and the coating width is regulated to a constant value. Furthermore, do not provide a plate or other piece on the side facing the paint leveling piece, or if the coating tool is a rectangular cylinder, the paint leveling piece on the bottom of the opposite side piece. Since the concave portion larger than the concave portion is formed, the coating material roughly applied to the panel surface in advance does not adhere to the piece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. The coating tool of the present invention comprises a plate-shaped coating leveling piece 1 having a predetermined width and a coating width position regulating plate 2 provided on the side surface thereof. FIG. 1 shows an example of a coating tool according to the present invention in which a quadrangular cylinder having a coating leveling surface opened and inclined at a required angle is formed. The side pieces inclined upwardly form the coating width position regulating plate 2.

The paint leveling piece 1 of the coating tool according to the present invention is
The tip has a height of 0.1 to 0.7 mm along the entire width
It is necessary to form the concave portion 3 of, and more preferably 0.2 to 0.5 mm. That is, as shown in FIG. 1, the tip of the paint leveling piece 1 is provided with a recess 3 above the piece and over the entire width thereof, and the paint leveling surface of the coating tool is brought into contact with the surface of the panel P. When done, paint leveling piece 1
The concave portion 3 is formed so that a slight gap having the above height is generated between the surface of the panel P and the surface of the panel P. In the present invention, if the concave portion 3 is smaller than 0.1 mm, the paint is scraped off too much to be applied uniformly, whereas if it is larger than 0.7 mm, the paint is not embedded in the deep hole and is applied to the hole portion after coating. The paint is not evenly coated due to the formation of recesses and the paint dripping. The shape of the recess 3 of this coating tool is
As shown in FIG. 3 (a), it is desirable that the depth is evenly provided over the entire width of the paint leveling piece 1.
As in (b) and (c), it may have a trapezoidal shape or a slightly arcuate shape. Further, when the tip of the paint leveling piece 1 is slightly inclined upward, the paint is leveled more uniformly.

The coating width position regulating plate 2 is provided on both edges of the paint leveling piece 1 so as to be perpendicular to the piece. That is, in the quadrangular cylindrical body in FIG. 1, the side piece forms the coating width position regulating plate 2, which is inclined upward and is inclined when the coating tool comes into contact with the panel P surface. If the tip of the coating leveling surface of the coating width position regulating plate 2 is also slightly inclined upwards like the tip of the coating leveling piece 1, the movement of the coating tool becomes smoother. The coating width position regulating plate 2 may be formed by bending the same material, or may be separately fixed by welding or the like.

Next, in the coating tool of the present invention, if the material to be used is not easily deformed, the side opposite to the coating leveling piece 1 is not particularly provided with a plate, a rod or the like and its cross section is reversed. It may be used as a U-shaped coating tool, but if it is a quadrangular cylinder with a reinforcing plate 4 on the side facing the paint leveling piece 1 as shown in FIG. It is also preferable from the above. On the other hand, in the case of this rectangular tubular body, the coating material that has been roughly applied beforehand in the form of a thin strip on the surface of the panel P has its reinforcing plate 4 formed.
It comes to adhere to the tip of the paint leveling surface side. Therefore, it is necessary to form a recess 5 larger than the recess 3 of the paint leveling piece 1 at the tip thereof. In that case, it is necessary to make the recess 5 larger than the recess 3 of the paint leveling piece 1 by three times or more. In addition, the opening of the quadrangular cylinder is not limited to the coating leveling surface side, and it is also possible to apply an opening on both sides.

As is apparent from FIG. 3 or 4, the method of using the coating tool of the present invention is that the surface of the panel P is roughly coated beforehand with a width narrower than the final desired coating width.
Only by moving the paint tool on the paint like dragging, the paint is uniformly applied to a predetermined width. At that time, if you apply a ruler to the side of the paint tool, it will be painted more straightly. The coating tool of the present invention is applied to a concrete-based panel, and particularly when applied to a lightweight cellular concrete-based panel having many irregularities and deep holes, its effect is remarkable.

[0014]

EFFECT OF THE INVENTION According to the coating tool of the present invention, when the coating material is applied in a strip shape having a predetermined width on the surface of a concrete-based panel such as a lightweight cellular concrete panel, the coating tool can be applied uniformly and easily. You will be able to paint easily and efficiently without the need for skill. In addition, it is preferable to coat the side surface of the panel, which is difficult to coat with a brush or a flat spatula.
