Abstract

(57) [Summary] [Structure] A roller-type coating tool, in which a valley-shaped annular recess 1a corresponding to a corner portion of an object to be coated is formed on the outer peripheral surface of the coating roller 1, and the annular recess An annular groove 1b is further formed on the bottom, and the paint supplied from the supply hole 7 of the paint supply pipe 2 for rotatably supporting the coating roller 1 is passed through the communication hole 8 formed in the coating roller. It is adapted to be supplied to the annular groove portion. [Effect] Since the paint supplied into the annular groove of the coating roller adheres to the edge portion of the corner portion and is coated thickly, it is possible to prevent the rust from prematurely occurring in the edge portion as in the conventional case. it can.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a roller type coating tool.

[0002]

[Prior Art]

 Normally, the steel structure is painted, and in the past, a person used a brush and overpainted it many times to obtain a predetermined film thickness.

[0003]

[Problems to be solved by the device]

 By the way, since the corners of the steel structure, such as the ends of the reinforcing member, are left to be mechanically cut or gas-cut, they become sharp edges, and as shown in FIG. There was a problem in that it was difficult to apply a thick coating to the edge portion C even if the edge portion C was painted many times, and thus rust was generated on such an edge portion C quickly.

Therefore, an object of the present invention is to provide a roller type coating tool capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the roller type coating tool of the present invention rotatably supports a coating roller at the other end of a paint supply pipe whose one end is connected to a paint supply device. On the outer peripheral surface, a valley-shaped annular recess corresponding to the corner of the object to be coated is formed, an annular groove is further formed at the bottom of this annular recess, and an opening is formed at the other end of the paint supply pipe. The coating roller is formed with a communication hole for supplying the paint supplied from the opening into the annular groove.

[0006]

[Action]

 In the above structure, the annular concave portion of the coating roller is brought into contact with the corner portion of the object to be coated so that the coating material is supplied into the annular groove portion through the opening and the communication hole of the coating material supply pipe, and the coating is performed. By moving the roller for use along the corner, it is possible to automatically coat the flat surface of the corner with a predetermined film thickness, and the edge is also supplied into the annular groove. Paint is attached and it is painted thick.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 is a coating roller of a coating tool for coating a corner portion B of a steel structure A which is an example of an object to be coated. One end 2a is connected to a coating material supply hose 3 on the coating material supply device side and a right angle. It is rotatably supported on the other end 2b side of the paint supply pipe 2 which is bent in the direction of 1. The brush for adjusting the paint film thickness (for example, a length of 0.5 ~ 1.0 mm) 4 is planted. The coating roller is positioned by a retaining ring 5 and a retaining nut 6.

On the outer peripheral surface of the coating roller 1, there is formed a valley-shaped annular recess 1 a having a shape that substantially matches the corner B of the steel structure A, and the center of the annular recess 1 a is formed. An annular groove portion 1b having a circular cross section is further formed in the bottom portion.

A paint supply hole (opening) 7 is formed in the center of the other end 2 b of the paint supply pipe 2, and the paint roller 1 is supplied from this supply hole 7. A plurality of communication holes 8 for supplying the coating material to the annular groove 1b, for example, 4 to 2 are formed. A plurality of supply holes 7 may be formed on the paint supply pipe 2 side.

Further, a paint supply stop cock 9 and a grip portion 10 are attached to one end 2a side of the paint supply pipe 2, and a cap 11 is attached to the other end.

Further, although a gap a is formed between the inner peripheral surface of the through hole 8 formed in the coating roller 1 and the outer peripheral surface of the paint supply pipe 2, the supply hole 7 of the paint supply is A sealant 12 for paint is installed in each of the gaps a on both sides and at the end of the coating roller 1.

In the above structure, when the corner portion B of the steel structure A is coated with this coating tool, as shown in FIG. 2, the annular recess 1 a of the coating roller 1 is aligned with this corner portion B. , And the cock 8 is opened to supply the paint into the paint supply pipe 2 to supply the paint into the annular groove 1b through the supply hole 7 and the communication hole 8.

Then, by moving the coating roller 1 along the corner portion B, the flat surface portion of the corner portion B can be automatically coated with a predetermined film thickness and the edge portion ( Also for the corner portion C, the paint D supplied in the annular groove portion 1b adheres and is thickly applied.

As described above, by using the coating roller 1 to which the coating material is automatically supplied, the predetermined film thickness can be obtained in one time, and therefore, compared with the conventional case of coating many times, It is possible to improve the efficiency of painting work.

By the way, in the above embodiment, the corner portion of the object to be coated has a substantially right-angled shape, but it may have, for example, an acute-angled shape or an obtuse-angled shape. The shape of the recess is adapted to these shapes.

[0016]

[Effect of the device]

 As described above, according to the configuration of the present invention, the coating roller is formed with the valley-shaped annular recess corresponding to the shape of the corner portion of the object to be coated, and the annular groove is further formed at the bottom of the annular recess. Since the paint supplied into the annular groove adheres to the edge portion of the corner portion and is coated thickly, it is possible to prevent the rust from prematurely occurring at the edge portion as in the conventional case.
