Description

  TECHNICAL FIELD The present invention relates to a spark holder used for performing welding and fusing operations and receiving sparks generated during welding and fusing operations.

  When performing welding work or fusing work at a construction site or the like, sparks or fireballs are generated. The generated sparks and fireballs are usually not processed at all, and the welding operation and the fusing operation are continued in a state of being scattered outside. As a result, there is a risk that burns or fireballs may fall on workers near the work place or below the work place, resulting in burns.

  Under such circumstances, at present, at least the sparks are prevented from diffusing outside the work place by covering the work area with a scaffold sheet. However, there are cases in which fire sparks and fireballs generated during work adhere to the scaffold sheet, and fires and blurs occur.

  In addition, while covering with the above scaffold sheet can surely prevent diffusion outside the work place, it cannot prevent the fall of sparks and fireballs from the work place, such as urethane placed near the work place. There was a risk of fire and blurring due to the sparks and fireballs falling on the outer wall materials of the fire.

  In order to prevent this, a plywood board or the like is laid under the work place to prevent the sparks and fireballs from falling below the work place. However, there is a possibility that a fire or a blur may occur due to the adhesion of sparks or fireballs to the plywood.

  In order to solve these problems, in Japanese Patent Laid-Open No. 8-33984 (Patent Document 1), there is a welding spark curing stand for preventing the sparks generated during welding work from being scattered outside and scattered downward. Proposed. This is because the deformed S-shaped vertical beam and the horizontal beam are fastened together, and the frame plate portion and the heat-resistant sheet are fastened to the deformed S-shaped vertical beam, so that they can be easily assembled and installed at a work site or the like. Is.

However, the welding spark curing stand described in Patent Document 1 must carry the assembly material up to the welding work site, and requires assembly work on the spot, which is complicated and poor in workability. Therefore, the present situation is not put into practical use.
Therefore, after all, we had to prepare for emergencies, for example, by having a bucket filled with water and a fire extinguisher near the work place.

Japanese Patent Laid-Open No. 8-33984

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a spark holder that can prevent fire powder and fireballs scattered during welding and fusing operations and can be safely operated. To do.

  In order to solve such a problem, the spark holder according to the present invention is used at the time of welding and fusing work, and has a substantially U-shaped upper side and both ends are substantially perpendicular to both ends of the upper side. A U-shaped abutting side that is abutted against and connected to a bag, a bag-shaped fire powder receiving portion that is provided at the lower side of the upper side and is connected to the upper side and the abutting side, and a predetermined point in the middle of the upper side of the upper side And a handle provided with a handle at the rear end.

  Moreover, this invention can be set as the structure by which the contact edge | side is provided with magnetism in the said fire powder receiving device.

  Furthermore, the present invention can employ a configuration in which the fire powder receiving portion is made of a wire mesh in the fire powder receiving tool.

  Further, the present invention can also be configured such that in the above-mentioned fire powder receiving tool, the entire outer surface of the fire powder receiving part is covered with a covering cover.

  According to the spark holder according to the present invention, the fire powder and fireballs generated by welding and fusing work are not scattered outside the work place and are not dropped below the work place. Can be eliminated completely, and it is possible to eliminate the trouble of curing work.
