Embodiment 1.
FIG. 1 is an explanatory diagram of the structure of a steel plate attaching jig 100 according to Embodiment 1. FIG. 1(a) is a rear view of the steel plate pasting jig 100, FIG. 1(b) is a side view of the steel plate pasting jig 100, and FIG. 1(c) is a front view of the steel plate pasting jig. . The steel plate attaching jig 100 is used to attach a thin decorative steel plate to a wall surface, for example, to attach an enameled kitchen panel to the wall surface. The enamel kitchen panel is a thin steel plate covered with a vitreous layer, and has a thickness of about 0.1 to 0.5 mm, a width of 800 to 1200 mm, and a length of 1800 to 2400 mm. The steel plate 50 to be stuck by the steel plate sticking jig 100 according to the first embodiment is not limited to the enamel kitchen panel, and may be made of other materials as long as they can be attracted by magnetic force. good. In addition, the surface to which the plate is attached by the steel plate attaching jig 100 is not limited to the wall surface of the building, and may be, for example, the ceiling surface, the floor surface, etc., and the surface to be attached is limited. not something to do.

The steel plate attaching jig 100 includes, as main structural members, a plate-like member 10 forming a curved surface 11 for holding the steel plate 50 and a frame 30 for maintaining the shape of the plate-like member 10 . The plate member 10 is, for example, a rectangular veneer plate, and is curved so that one surface is convex. A frame 30 is fixed to the other surface of the curved plate-like member 10 to maintain the shape of the plate-like member 10 . The plate member 10 has a top portion 16 between the longitudinal jig edges 12 , 13 , and the top portion 16 protrudes from the curved surface 11 .

The plate-like member 10 is rectangular, has dimensions slightly smaller than the steel plate 50 used, and is generally rectangular. The plate member 10 is curved in the longitudinal direction. The frame 30 is fixed along the longitudinal direction of the plate member 10 and maintains the shape of the plate member 10 curved in the longitudinal direction. In Embodiment 1, the frames 30 are fixed one by one to both ends of the plate member 10 in the width direction. The frame 30 has a grip portion 40 fixed to the surface opposite to the side to which the plate member 10 is fixed. The grip portion 40 is a portion that is gripped by the operator's hand when lifting the steel plate attaching jig 100 . The frame 30 and the grip portion 40 are fixed to each other to form a frame. Further, the frame 30 and the gripping portion 40 are combined with the plate member 10 to ensure the rigidity of the steel plate attaching jig 100 . Materials such as wood and aluminum are used for the frame 30 and the grip part 40, and they are preferably made of a lightweight material so that the operator can easily handle the steel plate attaching jig 100 by himself.

As shown in FIG. 1(b), the curved surface 11 of the plate-like member 10 is curved in an arc shape when viewed from the side, and has a radius of about 5000 mm, for example. Moreover, the curved surface 11 is bent in one direction. That is, the curved surface 11 has an arc-shaped contour in the direction perpendicular to the edge 12 or the edge 13, and the surface shape in the direction perpendicular to the edge 14 or the edge 15. has flattened contours. The curved surface 11 of the plate-like member 10 has a magnetic sheet 20 attached as a magnetic force member on the entire surface. The magnet sheet 20 attracts the steel plate 50 to the steel plate attaching jig 100 by magnetic force.

FIG. 2 is an explanatory diagram of the structure of a modified example of the steel plate attaching jig 100 according to the first embodiment. The magnet sheet 20 is not limited to being attached to the entire surface of the curved surface 11, and may be attached partially. In FIG. 2, the magnet sheet 20 is fixed to the plate member 10 at three locations. In addition to the configuration in which the magnet sheet 20 is attached to the surface of the curved surface 11, a neodymium magnet or the like may be attached to the back surface of the curved surface 11 of the plate-like member 10 or embedded in the plate-like member 10 forming the curved surface 11. . The steel plate attaching jig 100 can attract the steel plate 50 by providing a magnetic force member such as the magnet sheet 20 . By setting the magnetic force member to have an appropriate magnetic force, the force for removing the steel plate 50 from the curved surface 11 is not too strong, and the operation of attaching the steel plate 50 to the wall surface becomes easy. In other words, the steel plate 50 can be easily removed from the curved surface 11 after being attached along the curved surface 11 .

3 to 5 are explanatory diagrams of how to use the steel plate attaching jig 100 according to the first embodiment. Next, the operation of attaching the steel plate 50 to the wall surface 81 will be described with reference to FIGS. 3 to 5. FIG. The method of attaching the steel plate includes an adsorption step of adsorbing the steel plate to the curved surface 11, an adhesive material installation step, and a pressing step of pressing the steel plate 50 adsorbed to the curved surface 11 against the wall surface.

As shown in FIG. 3, the steel plate 50 is placed on a workbench 80. As shown in FIG. The steel plate 50 is placed with the decorative surface 51, which is the front side of the wall when attached to the wall surface 81, facing upward. That is, the attachment surface 52, which is the surface on which the steel plate 50 is attached to the wall surface 81, faces the workbench 80 side. The steel plate 50 is cut to a required size on a workbench 80, and the cut edges 53, 54, 55, 56 are subjected to antirust treatment. This process is called a pretreatment process.

An adsorption step is then performed. The steel plate attaching jig 100 sequentially presses the curved surface 11 to which the magnet sheet 20 is attached from the jig edge 13 side toward the jig edge 12 side. Since the magnetic sheet 20 is fixed to the curved surface 11 , the magnetic force of the magnetic sheet 20 attracts the steel plate 50 to the curved surface 11 side of the steel plate attaching jig 100 . A portion where the steel plate 50 and the magnet sheet 20 first contact on the jig edge 13 side is referred to as a contact portion 90 . In FIG. 3A, only a part of the steel plate bonding jig 100 on the side of the jig edge 13 is in contact with the steel plate 50. The steel plate affixing jig 100 is moved so that the contact portion 90 moves toward the curved direction). Then, as shown in FIG. 3B, when the contact portion 90 moves toward the other jig edge 14, the steel plate 50 is attracted to the surface of the magnetic sheet 20 of the steel plate attaching jig 100. .

The steel plate attaching jig 100 can lift the thin steel plate 50 by bringing the thin steel plate 50 into contact with a magnetic member such as the magnetic sheet 20 attached to the curved surface 11 . Therefore, since it is not necessary for the operator to directly grip the thin steel plate 50, the risk of bending the thin steel plate 50 and leaving marks is reduced.

Next, an adhesive material placement step is performed. As shown in FIG. 4 , the attachment surface 52 of the steel plate 50 is provided with double-sided adhesive tapes 61 and 62 and an adhesive 63 . The double-sided adhesive tapes 61 , 62 and adhesive 63 are collectively referred to as adhesive material 60 . The double-sided adhesive tapes 61 and 62 are arranged in a grid pattern, and an adhesive 63 is applied to the portions surrounded by the double-sided adhesive tapes 61 and 62 . The double-sided adhesive tapes 61 and 62 are attached to positions separated from the edges 53, 54, 55 and 56 of the steel plate 50 by about 5 mm. The step of installing the adhesive material can be performed in a state where the steel plate 50 is adsorbed to the steel plate attaching jig 100 . As a result, after the adhesive material 60 is placed on the steel plate 50, the next pressing step can be performed without gripping the steel plate 50. FIG.

Next, a pressing process is performed. In the pressing step, as shown in FIG. 5, the curved surface 11 of the steel plate pasting jig 100 holding the steel plate 50 is directed toward the wall surface 81, and the steel plate pasting jig 100 is positioned on one jig edge 13 side. The edge 54 of the steel plate 50 is pressed against the wall surface 81 . After the edge 54 of the steel plate 50 is pressed against the wall surface, the steel plate attaching jig is moved so as to sequentially move the contact portion 91 between the attachment surface 52 of the steel plate 50 and the wall surface 81 toward the edge 53 of the steel plate 50 . Move 100. That is, the contact portion 91 moves in the arrow direction in FIG. 5 by moving the steel plate attaching jig 100 along the curved surface 11 . The sticking surface 52 of the steel plate 50 is provided with double-sided adhesive tapes 61 and 62 . Therefore, the steel plate 50 and the wall surface 81 are sequentially fixed at the contact portion 91 . When the steel plate 50 is adhered to the wall surface 81 side, the decorative surface 51 of the steel plate 50 is gradually separated from the surface of the magnetic sheet 20 of the steel plate attaching jig 100 . The adhesive force of the double-sided adhesive tapes 61 and 62 is set stronger than the force of the magnetic sheet 20 that attracts the steel plate 50 . Therefore, the steel plate 50 is attached to the wall surface 81 by pressing the curved surface 11 along the wall surface 81 from one edge 54 of the steel plate attaching jig 100 toward the other edge 53 of the curved surface 11 . It can be peeled off from the magnet sheet 20 provided on the curved surface 11 while being attached and fixed.

The steel plate 50 is set larger than the curved surface 11 of the steel plate attaching jig 100 . Edges 53 , 54 , 55 , 56 of steel plate 50 protrude from steel plate attaching jig 100 , so that steel plate 50 can be positioned on wall surface 81 . The protrusion amount of the steel plate 50 from the curved surface 11 is set to about 50 mm to 100 mm at the jig edges 12 and 13 of the curved surface 11 . At the edges 14 and 15 of the jig in the width direction of the curved surface 11, the protrusion amount may be set to a large value of 200 mm to 300 mm.

The attachment of the steel plate 50 using the steel plate attachment jig 100 is performed as described above. The steel plate attaching jig 100 can be lifted by a worker grasping the grip portion 40 or the frame 30 . Therefore, the operator can carry the steel plate 50 and position it with respect to the wall surface 81 without grasping and holding the steel plate 50, and the work of pressing the steel plate 50 against the wall surface 81 is also performed by operating only the steel plate attaching jig 100. be able to. Therefore, it is possible to reduce the number of personnel for the operation of attaching the steel plate 50, and to reduce the cost of installing the decorative steel plate on the wall surface.

Further, the steel plate attaching jig 100 is provided with a top portion 16 between the jig edges 12 and 13, and a curved surface 11 is formed from which the top portion 16 protrudes. Since the steel plate 50 is attracted along the curved surface 11, the warpage of the steel plate 50 is corrected. The steel plate 50 is generally manufactured from a material obtained by rolling a thin steel plate into a roll. Further, the steel plate 50 is, for example, a steel plate 50 that has been enameled, and may be rolled into a cylindrical shape when shipped after manufacturing. Therefore, since the steel plate 50 having such a warp can be attached to the wall surface 81 while being sucked and held along the curved surface 11, there is an advantage that the attachment accuracy of the steel plate 50 is improved. In addition, since the steel plate attaching jig 100 supports the thin steel plate 50 by the curved surface 11 and attaches it to the wall surface, it is possible to suppress bending and plastic deformation due to its own weight, so that the work can be performed safely, simply, and accurately. It has the advantage that it can be implemented

In addition, since the magnetic sheet 20 has a small magnetic force per unit area but attracts the steel plate 50 over a wide area, the steel plate 50 is held along the curved surface 11 of the steel plate attaching jig 100 without falling off when being carried. . On the other hand, when the steel plate 50 is peeled off from the steel plate attaching jig 100, the steel plate 50 is sequentially peeled off from the edge 53 or edge 54 side. If the adhesive force of the double-faced adhesive tapes 61 and 62 is greater than the above, the steel plate 50 is fixed to the wall surface 81 side and separated from the magnet sheet 20 .

Although the present invention has been described above based on the embodiments, the present invention is not limited only to the configurations of the above-described embodiments. For example, the curved surface 11 may have a cross section of not only a circular arc but also an elliptical arc, a parabola, a hyperbola, or a shape similar thereto. Since the curved surface 11 is a continuous surface that allows smooth movement of the contact portion on the workbench 80 or the wall surface 81, the thin steel plate 50 with low rigidity can be attached without causing wrinkles or distortion. . Further, the frame 30 and the grip portion 40 may have other forms as long as they can maintain the shape of the curved surface 11 and are easy for the operator to hold. Also, in the above description, an example in which the steel plate 50 is attached to the wall surface 81 has been described, but other materials can be used as long as they are attracted to the magnetic members. In short, it should be noted that the gist (technical scope) of the present invention also includes various modifications, applications, and the scope of utilization made as necessary by those skilled in the art.
