The sealing performance will be sufficiently exhibited.

(panel)
In this embodiment, the panel 10 is described as an example of an aluminum honeycomb panel having a rectangular face plate, but the panel 10 of the present invention is not limited to the aluminum honeycomb panel. As is well known, an aluminum honeycomb panel is configured by arranging a core material formed in a honeycomb shape surrounded by a frame material between an upper surface plate and a lower surface plate formed in a rectangular shape. (See FIGS. 1 and 2). After applying the adhesive material to the surfaces of the upper surface plate and the lower surface plate facing each other, the members are bonded by pressing the frame material and the core material between the upper surface plate and the lower surface plate. Each member is formed as an aluminum honeycomb panel firmly integrated with an adhesive.

  Further, packings are respectively attached to the connection portions on the outer peripheral side of the upper surface plate, the lower surface plate, and the frame material as illustrated. A bolt hole for mounting (not shown) for inserting the threaded portion 5c of the waterproof bolt 5 into a plate nut 8 to be described later, which is charged in the frame material, is formed at the end of the panel 10. The plate nut 8 is fixed in advance at a predetermined position in a holding groove provided in the upper part of the frame member disposed at the end of the panel 10 (see FIG. 2).

(Attaching the panel to the support member)
The attachment of the panel 10 to the support member 1 in this embodiment will be described.
As shown in FIGS. 1 and 2, when attaching the panel 10 to the support member 1, the mounting body 3 a of the mounting bracket 3 is applied to the bracket 2 provided on the supporting member 1, and a washer is inserted into the mounting hole of the mounting bracket 3. The mounting bracket 3 is fixed to the bracket 2 of the support member 1 by inserting and tightening bolts and nuts 4. In this embodiment, an example in which the bolts and nuts 4 are attached is shown, but two or more bolts and nuts 4 may be attached.

  At this time, in the support portion where the end portions of the adjacent panels 10 are attached, the mounting brackets 3 and 3 are attached to both side surfaces of the bracket 2 as shown in the drawing, and the common bolts and nuts 4 are attached. In this case, the bolts and nuts 4 may be tightened to the extent that they are temporarily tightened, and as will be described later, the bolts and nuts 4 may be finally tightened after being parallel to the panel 10. In the support of the panel to be connected, only the extreme end of the panel 10 is supported by the mounting bracket 3 in the support portion of the panel 10 which is the extreme end.

  On the other hand, the panel 10 may be mounted on the ground or on a place such as a mounting table where the scaffolding is good or where the waterproofing bolt 5 can be screwed easily. The waterproof bolt 5 is attached by screwing the waterproof bolts 5 and 5 into a plate nut 8 in which a rotation-preventing plate is fixed in advance at a predetermined position of a holding groove provided in the frame material of the panel 10. At that time, by attaching the sealing material 6 and screwing the lower threaded portion 5c of the waterproof bolt 5 through the mounting bolt holes formed in the panel 10, the waterproof bolts 5 and 5 are securely attached to the panel 10 side. Can be fixed to.

  Thereafter, the panel 10 to which the waterproof bolts 5 and 5 are fastened is lifted to the mounting position, and the other side of the waterproof bolts 5 and 5 is inserted into the long holes of the support legs 3b and 3b of the mounting brackets 3 and 3 attached to the support member 1. The screw parts 5c and 5c are inserted. Thereafter, the nuts 7 and 7 are screwed onto the screw portions 5c and 5c protruding from the support legs 3b and 3b of the mounting bracket 3 so that the panel 10 is supported by the support member 1.

(Waterproof panel joints and supports)
The joints formed at the ends of the panels 10 and 10 supported by the support member 1 are coated with a waterproof sealing agent using a caulking gun (not shown) to form the joint caulking material 11. In this case, when the notch 9, 9 is formed in each fitting 3, the caulking gun or the like is inserted through the notches 9, 9 in the application of the sealing agent to the joints below the fittings 3, 3. This can be done easily. Since the sealing agent to be applied is the same material as the packing at the ends of the panels 10 and 10, it has high adhesiveness and high waterproofness to the joints of the panel.

(Waterproof inside the panel)
In addition, the parts used between the panel 10 and the mounting bracket 3 in this embodiment are only the waterproof bolts 5 with the sealing material 6 attached, and the waterproofing for the bolt holes which are support holes formed in the panel 10 itself is as follows. It is performed by the sealing material 6 attached to the waterproof bolt 5, and it is a great feature that it can be achieved with the smallest number of parts.

  As described above, the plate nut 8 fixed to the frame material of the panel 10 and the waterproof bolt 5 are fixed so that the bolt hole for inserting the threaded portion 5c of the waterproof bolt 5 penetrates the frame material and the upper surface plate of the panel 10. The waterproof bolt 5 is fixed through the bolt hole. For this reason, conventionally, when rainwater from the outside is immersed in the panel 10 through the bolt holes, there has been a problem that the bonding performance is deteriorated with respect to the adhesive material to which the respective members of the panel 10 are bonded. .

  On the other hand, in the waterproof structure of this embodiment, as described above, the waterproof construction with the sealing material 6 for the bolt holes of the panel 10 is completed at the same time when the waterproof bolt 5 is screwed into the panel 10. . When the waterproof bolt 5 is screwed in, the sealing material 6 attached to the waterproof bolt 5 is compressed and deformed to seal between the surface of the panel 10 and the flange 5a of the waterproof bolt 5. In this embodiment, the rainwater intrusion path from the outside is only a path that enters between the edge 5d formed on the flange 5a of the waterproof bolt 5 and the surface of the panel 10 and enters the bolt hole. As indicated by the arrow in FIG. 2, since the flange 5a is integrally provided, the waterproof bolt 5 itself has no gap into which rainwater enters. That is, the waterproof bolt 5 having the sealing material 6 attached to the panel 10 is firmly attached, and at the same time, the inside of the panel 10 becomes a sealed space.

The panel 10 is usually in a state where the plate nut 8 is fixed to a predetermined position on the panel 10 until the panel 10 is carried into the site, and the bolt hole is still open. Prior to the work of attaching the panel 10 to the support member 1, at the stage where the waterproof bolt 5 is screwed and fixed to the plate nut 8 fixed to the panel 10, the bolt holes of the panel 10 are sealed as described above. 10 is a sealed space.
Therefore, according to the panel support structure of the present embodiment, even in the course of installation, it penetrates through the inside of the bolt / nut 104 and the waterproof washer 105 as in the conventional example shown in FIG. Since the gap does not exist at the stage where the waterproof bolt 5 is screwed and fixed, it is possible to reliably prevent rainwater from entering the bolt hole of the panel 10 from the outside.
