Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to an apparatus for spraying a fireproof coating onto the surface of a steel frame that constitutes a steel frame building.

[Conventional technology]

In steel-framed buildings, it is mandatory to spray fire-resistant coating onto the surface of the steel frame that is not covered with concrete, etc. Previously, workers held a nozzle to spray the fire-resistant coating onto the steel frame surface, or installed it on a trolley. A spray nozzle attached to the tip of a manipulator sprays the fireproof coating material onto the surface of the steel frame.

[Problem to be solved by the invention]

When spraying by workers, not only is there a safety issue as the workers often have to work on scaffolding, etc., but the sprayed fireproofing material may bounce off and fall on the workers, creating a hazardous work environment. In addition to being inferior, skill is required to spray the fireproof coating material onto the surface of the steel frame evenly and smoothly.

In the above-mentioned spraying equipment, the manipulator swings up and down, so controlling the movement of the manipulator in order to move the nozzle in a straight line and spraying onto the flat surface of the steel frame is very difficult and troublesome, so the control device suffers a great loss. This results in increased weight and cost.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a spraying device capable of solving the above-mentioned problems.

[Means and effects for solving the problem] An X-axis movement guide bar 15 is provided on the vertically swingable mounting member 10, and an X-axis moving body 16 that slides along the X-axis movement guide bar 15 is provided. A guide bar 17 for Y-axis movement is attached, and a nozzle 19 is swingably provided on the Y-axis moving body 18 that slides along the guide bar 17 for spraying. , the nozzle 19 can be moved linearly in a predetermined plane range for spraying by moving linearly in the Y-axis direction, and the operation at that time can be easily controlled, making the control device simple and inexpensive.
