Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a curing sheet for sparks or the like used to protect a window glass during construction work such as welding performed around the window glass, or to protect a pillar or a wall surface at a construction site. is there.

[0002]

[Prior art]

 After putting the window glass into the opening on the outer wall of the building, when installing blind boxes or performing welding work such as piping work, the glass may be contaminated, damaged or damaged by sparks or falling objects. In order to prevent this, a thin veneer plate, which has been made to fit the size of the window glass, is fixed to the interior glass surface of the window glass with tape, etc., and the sheet is placed on top of the glass surface. It was attached with fasteners etc. on the precast concrete board to perform double spark curing.

[0003]

[Problems to be solved by the device]

 According to the conventional example, the veneer plate and the sheet each require time and labor for mounting them, and since they are double-cured, the above-mentioned problems occur remarkably and the structure is complicated. . In addition, the plywood was warped when exposed to the sun, could not be used for a long time, and the materials were wasted.

An object of the present invention is to have a simple structure, to perform curing work extremely easily, easily, and quickly, and to reduce the material cost.

[0005]

[Means for Solving the Problems]

 The protective sheet for sparks and the like according to the present invention is a sheet body having a size that covers the protective surface, and a plurality of sheet fixings that are attached to the sheet body and can be adsorbed to the protective surface facing the sheet body. It consists of a suction cup for. The protective surface protected by the curing sheet includes the glass surface or wall surface of the window glass. The sheet body having a size that covers the protective surface is formed of one sheet or a combination of a plurality of sheets. When the curing sheet is applied to a window glass, it is possible to escape sparks and the like downward by forming an extension at the lower part of the sheet body.

[0006]

[Action]

 The suction cup sucks onto the protective surface such as the glass surface to fix the sheet body and protect the protective surface from sparks.

[0007]

【Example】

 As a first embodiment of the present invention, an example applied to a curing sheet for window glass will be described with reference to FIGS. The curing sheet 1 includes a sheet body 2 and a plurality of suction cups 3 attached to the sheet body. The sheet body 2 is made of one heat-resistant sheet material and is formed to be a little larger than the size of the glass surface Ga on the indoor side which is the protective surface of the window glass G to be protected so that the glass surface can be covered. Then, it is formed in a substantially square shape. The suction cups 3 are attached around the sheet body 2 at a predetermined interval. As shown in FIG. 1, the suction cup 3 is arranged on the upper side and on both the left and right sides slightly apart from the edge portion of the sheet body 2, and on the lower side a predetermined distance d from the lower edge portion. The lower portion of the sheet body 2 is formed with an extension portion 2a corresponding to a length of a predetermined distance d, and the sheet body is longer than the lower portion of the window glass G by the length of the extension portion, that is, the distance d (FIG. 4). ).

The suction cup 3 is for closely contacting this with the glass surface Ga of the window glass G to fix the sheet body and to protect the glass surface from sparks and the like. As shown in FIGS. 2 and 3, the suction cup 3 includes a suction cup 3a, a protrusion 3b, and a split pin 3c. The suction cup portion 3a is located on the front surface, which is the surface facing the window glass G of the sheet 2, and the projection portion 3b is projected to the back surface of the sheet body through the hole 2b formed in the sheet body. The almost U-shaped split pin 3c, which is inserted in a penetrating state, prevents the strip from being detached from the sheet body. The suction cup 3 can be removed from the front surface of the sheet body 2 by pulling out one piece of the split pin 3c from the protruding portion 3b.

Next, the usage method will be described. As shown in FIGS. 3 and 4, after the window glass G is inserted into the opening of the outer wall W through the window frame sash S, the front surface of the sheet body 2 is made to correspond to the glass surface Ga and the upper side of the sheet body is Of the window frame sash S fitted into the opening of the outer wall W by sequentially adhering the suction cups to the glass surface from the suction cups 3 located on the both sides to the suction cups located on the lower side. It hangs on the inside of Sa under. Since the size of the sheet body 2 is slightly larger than the window glass G, both side edges of the sheet body reach the left and right vertical frames of the window frame sash of the window glass, and sparks or the like are generated on both side edges of the sheet body. Therefore, it is prevented from penetrating between the sheet body and the glass surface Ga. When the blind box or the like is welded in this state, the sheet surface 2 protects the glass surface Ga of the window glass G from sparks and the like, and the extension 2a allows the sparks to escape to the slab surface.

A second embodiment of the present invention will be described with reference to FIGS. 5 and 6. In this example, the sheet body 12 of the window glass curing sheet 11 does not have the above-mentioned extension 2a, the number of suction cups 13 to be attached, and the suction cups are arranged at the four corners of the sheet body 12. Thus, the configuration is different from that of the first embodiment, but other configurations are substantially the same. The method of use is also the same as in the first embodiment.

Although each of the curing sheets 1 and 11 described above is formed of one sheet body 2 and 12 which is slightly larger than the size of the window glass G, depending on the size of the window glass, a plurality of sheet bodies may be used. Of course, it may be formed by. For example, in the example of the curing sheet 21 shown in FIG. 7, two sheet bodies 22 and 22 are formed in combination, and the end portions of the sheet bodies are overlapped with each other so that no gap is generated between the sheet bodies during use. 23 is a sucker.

Further, it goes without saying that the attachment position of the suction cup is not limited to the periphery of the sheet body. The suction cups may be provided not only on one side of the sheet body as in the above example but also on both sides.

The scope of application of the curing sheet of the present invention is not limited to window glass, and can also be applied as a curing sheet for protecting, for example, damage or dirt on the surface or wall of a pillar of a building under construction.

[0014]

[Effect of device]

 According to this invention, the curing sheet is fixed by a suction cup that can be attached to and detached from a protective surface such as a glass surface, so the configuration is simple, and the curing sheet can be attached and removed easily and quickly. It is possible to reduce the work process, reduce the material cost, and the curing work can be done by a small number of workers. By providing an extension on the sheet body of the curing sheet, sparks and the like can be released to the slab surface, so that there is no possibility that sparks or the like will fall under the window glass.
