7 is an external view of a building using the fixing device of the present invention, and FIG.
FIG. 7 is a schematic front view showing a main part of the building shown in FIGS. 5 and 6.

The plate material 1 according to the present invention is structurally disposed not only on the wall surface of a general building but also on any surface portion such as a floor or a roof. Although it is intended for the plate material 1 made of, it also includes other lightweight panels such as concrete, wood, and metal in a broad sense.

The plate material 1 shown in the figure is, for example, bonded to the middle of a plate material 1A such as float glass and a plate material 1B such as reinforced glass with an intermediate layer 1C such as a resin or acrylic resin having adhesiveness and translucency. And the shape of the mounting hole at the edge portion is improved. Specifically, a large-diameter first mounting having substantially the same shape as the head portion 5A of the bolt 5 is attached to the plate material 1A which is an outer layer of the plate material 1. A plate material 1B which forms the hole 1a and serves as an inner layer of the plate material 1
To the second mounting hole 1b having a small diameter and having substantially the same shape as the neck portion of the bolt 5.
By forming the, the fastening with the fixing device 2 by the bolt 5 is strengthened and the designability after construction is improved. Further, by selecting the reinforcing glass for the plate material 1B which is the inner layer of the plate material 1, the structure is formed to withstand the stress generated around the bolt 5.

The fixing device 2 according to the first embodiment of the present invention is shown in FIG.
As shown in the schematic cross-sectional view of FIG. 3, a receiving member 3 provided with a bolt insertion hole for fastening a bolt 5 into which the mounting hole 1a of the edge portion of the plate 1 is inserted and a flange having an annular flat surface are provided on the front end surface. 5, a support arm 4 for projecting the receiving member 3 toward the plate member 1 side, and a support member 6 for supporting the support arm 4 and fixing it to a structure such as an upright or wire cable as shown in FIG. Consists of.

An annular groove 5a. Is formed in the contact surface of the head portion 5A of the bolt 5 with the plate material 1 and the contact surface of the receiving portion of the receiving member 3 with the plate material 1. 3a are formed, and the concave grooves 5a. An annular first elastic member 7 is arranged in each of 3a.

The bolt 5 located in the mounting hole 1b of the plate member 1 is spaced apart from the outer periphery of the neck of the bolt 5 by a predetermined distance.
The protrusions 5b of the strip are formed, and the second elastic member 8 including an O-ring or the like is disposed between the protrusions 5b.

In order to dispose the plate members 1 on the surface of the building by the fixing device 2, after the end edges of the plate members 1 are butted against each other via the seal member 9 formed of a filler such as a silicone sealant, the respective plate members 1 are abutted. The bolt 5 is inserted from the outer surface of the plate member 1 into the mounting hole 1a, the bolt 5 is inserted into the bolt insertion hole of the receiving member 3 of the fixing device 2, and the bolt 5 is tightened from the back side of the receiving member 3 with the fastening nut 3A. After fastening and fixing, and further inserting the split pin 3B (not shown in FIGS. 1 and 2) for preventing rotation from the body, the cap 3C is capped from the rear. The inside of the mounting hole 1a is filled with a sealing material such as a silicone sealant from the surface to form a watertight structure.

By the way, in this type of fixing system, the wind pressure applied to the plate material 1 is an evenly distributed load perpendicular to the surface of the plate material 1. Therefore, the head surface of the bolt 5 and the contact surface of the plate material 1 are contacted with each other. Maximum bending stress is applied, but in the above configuration,
The stress generated on the contact surface of the plate member 1 is relieved by the deformation of the first elastic member 7.7 that holds the plate member 1 therebetween. As shown in FIG. 2, this structure is also useful when the plate member 1 is fixed at a slight angle or a plate member having a curved surface such as curved plate glass is used.

The stress generated by the interlayer displacement due to an earthquake or the like is caused by the outer circumference of the neck portion of the bolt 5 and the mounting hole 1a. 1
b, in detail, the maximum stress is applied to the contact portion with the small-diameter mounting hole 1b provided in the plate material 1B, but is applied to the inner peripheral surface of the mounting hole 1b by the second elastic member 8 at the neck portion of the bolt 5. Since the stress is relieved, the in-plane displacement is buffered.
The mounting holes of the plate member 1 are composed of the mounting holes 1a of the plate member 1A and the holes 1b of the plate member 1B.
a. When a slight deviation occurs in 1b, the second elastic member 8 plays a role of absorbing a construction error. It is needless to say that these elastic members 7.8 can maintain high airtightness and watertightness.

FIG. 3 is a schematic sectional view of the fixing device 2 of the second embodiment. In the fixing device 2 of this embodiment, the first
Of the elastic members 7.7, the first elastic member 7 arranged on the head 5A of the bolt 5 and the second elastic member 8 arranged on the neck of the bolt 5A are formed integrally with the bolt 5. There is. These elastic members 7.8 are formed integrally with the metal bolt 5 by insert molding or outsert molding. With this structure, construction is easier and cost can be reduced. it can.

As described above, the fixing device disclosed in the above embodiment is not limited to a building having a plane structure, and, for example, as shown in FIG. As shown in FIG. 6, it can be effectively used for a building having a curved surface structure (a wall surface having a large curvature) that requires the use of the plate material 1 having a curved surface.

When forming a wall surface having a small curvature in the above-mentioned building, the support arm 4 is moved depending on the angle of the joint portion between the plate members 1 as in the third embodiment shown in FIG. The support member 6 is attached at a predetermined angle to the support member 6, or as shown in FIG. 7, a mounting shaft 4a is provided at the center of the curved support arm 4 so that the support arm 4 is horizontal to the support arm 4. The plate member 1 is supported so that it can rotate in the plane.
The bolts 5 corresponding to the mounting holes 1a of 1 are arranged on the virtual line 1 that hangs radially from the apex of the building, and construction is performed.

Since the fixing device of the present invention is provided with the elastic member for relieving the stress generated around the mounting hole of the plate member, wind pressure is applied to the plate member or the joint portion of the plate members is made to have a predetermined angle. Even when installed, the stress applied to the mounting holes in the edge portion of the plate material can be relaxed, and the airtightness and watertightness inside and outside the building can be maintained, and a building with an excellent appearance design can be constructed. As a result, it is an epoch-making and meaningful invention that enables the construction of a building that is safer and has an excellent appearance design.
