FIG. 16A is an explanatory view for explaining attachment of two panels and a reinforcing member of a door body of a home door device according to a seventh embodiment of the present invention, and FIGS. 16B and 16C are home door devices according to a seventh embodiment of the present invention. It is a schematic sectional drawing which shows the attachment state of two panels of a door body, and a reinforcement member.
In the first embodiment, the case where the reinforcing member 22 is joined to the panel 21 of the door body 2 with the double-sided adhesive tape 22a has been described. In the seventh embodiment, the panel 82, the panel 83, and the support frame 81 of the door body 2 are provided. Will be described with reference to the case where the reinforcing member is joined by a double-sided adhesive tape 81a formed of a waterproof material.

  16A, 16B, and 16C, the panel 82 and the panel 83 constituting the door body 2 are formed by bending a portion including an edge which is one end surface of the panel 82 into an L-shape. The edges, which are the respective end surfaces, of the panel 83 are abutted, and are attached and joined to a reinforcing member constituting the support frame 81 using a double-sided adhesive tape 81a formed of a waterproof material. At the butting portion 84 between the edges forming the seam where the edges of the panel 82 and the panel 83 are butted together, the double-sided adhesive tape 81a covers the butting portion 84 over the panel 82 and the panel 83. Here, the double-sided adhesive tape 81a formed of a waterproof material is used, but as the base material of the double-sided adhesive tape 81a, a waterproof material includes a rubber-based or polyethylene-based material, but is not limited thereto. . In FIGS. 16B and 16C, the positional relationship between the two panels 82 and 83, the support frame 81, and the double-sided adhesive tape 81a is shown in a schematic cross section, and is not joined for simplicity. FIG. 16C is a schematic cross-sectional view showing another attachment state. In FIG. 16B, the double-sided adhesive tape 81a having an L-shape in a sectional view in the joined state is changed to a U-shape in FIG. are doing. By increasing the bonding area, the bonding strength between the support frame 81 and the panel 82 is improved.

  The butt portion in the present embodiment has been described with respect to the butt portion generated when the edges, which are the end surfaces of the two panels, are butted. However, the present invention is not limited to this, and as shown in FIG. It may be a butt portion generated when the sheet is bent. Further, in the present embodiment, the double-sided adhesive tape formed of a waterproof material is used. However, the present invention is not limited to this, and in the installation of the home door device at a place where the waterproof property is not required, the home door device is formed of a non-waterproof material. A double-sided adhesive tape may be used. In that case, there is an effect of suppressing entry of dust and foreign matter into the inside of the door.

When connecting the panels 82 and 83 and the support frame 81 in this way, by joining each with the double-sided adhesive tape 81a, there is no distortion due to heat reception and cooling as in the case of joining by conventional welding, There is an effect that the panels 82 and 83 do not undergo torsional deformation, and that spatter generated by welding does not damage the surfaces of the panels 82 and 83. In particular, since welding is not used, application to painted steel plates is also possible. Becomes
In addition, a double-sided adhesive tape 81a made of a waterproof material is attached to the inside of the door body 2 through the butting portion 84 while covering the butting portion 84 over the panel 82 and the panel 83. Water can be prevented from entering, and there is an effect that corrosion measures (for example, waterproof treatment by applying a sealant) which is required in the butt portion 84 which is a joint portion of the panel in the related art are unnecessary. With such a structure, manufacturing costs can be reduced.

  It should be noted that the present invention can be freely combined with the embodiments within the scope of the invention, or can be modified or omitted as appropriate, and the present invention is limited by the above embodiments. is not.
