DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel body as a roofing material having rigidity, for example, also serving as a structural material, and being directly attached to a column, and more particularly, to a panel body for mutually joining panel bodies. It is about structure.

[0002]

2. Description of the Related Art FIG. 3 is a sectional view showing a conventional honeycomb panel (panel body) joint structure. This joint structure
The panel body 50 constituting the wall is joined in an in-plane direction, and a joining block 56 for joining is welded to the frame 55 of the panel body 50.

[0003] When such panel bodies 50 are joined to each other, the end faces of the joining blocks 56 are brought close to each other, and are straddled between the joining blocks 56, on both sides thereof. Connecting plates 51 and 52 are additionally provided. Then, both joining blocks 56, 56 and both connecting plates 51,
52 is clamped and fixed by a high tension bolt 53 and a nut 54. Thus, the panel bodies 50, 50 are joined to each other via the connecting plates 51, 52 and the joining blocks 56, 56.

[0004]

However, in joining such a conventional panel body 50, a high tension bolt 53 is required.
In this case, the joining block 56 is tightened with a strong force, so that the joining block 56 is required to have high rigidity that can withstand compressive deformation. In this case, if the joining block 56 is formed integrally with the frame 55 of the panel body 50,
On the other hand, if the cost is increased, if the frame is a separate body, it must be welded to the panel body side of the frame 55, and the production is troublesome.

When the panel body 50 is firmly joined by using the high tension bolts 53, the contact surfaces of the connecting plates 51, 52 and the joining blocks 56, 56 are surface-finished and managed during construction. Is complicated. Furthermore, when the panel body 50 is applied as a roof material, there is a problem that a repeated load is applied between the panel bodies 50, 50 due to wind pressure, snowfall, and the like, and the bolts 53, 53 are easily loosened.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to easily perform manufacturing and construction, and to provide a panel body capable of firmly joining the panel bodies to each other. It is intended to provide a joint structure.

SUMMARY OF THE INVENTION A panel body joining structure according to the present invention is a panel body joining structure in which panel bodies that also serve as structural materials themselves are joined in an in-plane direction. Bonding pieces provided at the side ends in the bonding direction, and a connecting plate provided on both front and back surfaces across the two bonding pieces in a state where the end faces of these bonding pieces are brought close to each other, It has a bolt for holding and fixing both joint pieces and both front and back connecting plates in a direction orthogonal to the joining direction, and each joint surface of each joint piece and each connecting plate has an uneven portion which is engaged with each other. It is characterized by having been done.

According to this structure, the concave and convex portions formed on the front and back surfaces of the two joint pieces are engaged with the concave and convex portions formed on the joint surface of the connecting plate attached to the two joint pieces. And since the connecting plate is clamped and fixed with bolts in the direction perpendicular to the joining direction, the unevenness makes it difficult for the two panel bodies to be displaced by the tension, compression and rotation force generated between the two panel bodies. It is possible to make a bonded state having a certainty. As a result, even when a bolt other than a high-tensile bolt is used to fasten the joining piece and the connecting plate, the panel bodies can be joined to each other by the same rigid joining as when using a high-tensile bolt. it can. Further, since the influence on the bolt can be reduced, the bolt can be prevented from being loosened.

Therefore, in the present invention, since it is not necessary to use a high tension bolt, it is not necessary to form the joining piece with a member having extremely high rigidity, and it is not necessary to manage the surfaces of the joining piece and the connecting plate. .

[0010] The panel body includes a honeycomb core material, a panel frame disposed on the outer periphery of the honeycomb core material, and an outer plate and an inner plate adhered to the front and back of the honeycomb core material and the panel frame, respectively. The joining piece is preferably formed by extending the side end of the panel frame in the joining direction of the panel body.

According to this configuration, by using a so-called honeycomb panel, the panel body can be configured to be lightweight and high in strength, and the panel body can have the function of a structural material. Further, the joining piece and the panel frame can be integrally formed.

Further, it is preferable that the front and back connecting plates are formed so that the portions corresponding to the gaps of the joint pieces are all bent at the same angle.

According to this structure, the panel members are joined to each other by the connecting plate in which the predetermined portions are bent at the same angle, so that the curved surfaces can be formed as a whole without forming the panel members themselves. It can be easily applied to the required structure.

b, 5b and the connecting plates 11, 12 are clamped and fixed by bolts 21, 21 in a direction orthogonal to the joining direction,
The panel bodies 1 are joined to each other. For this reason, the panel bodies 1 and 1 are less likely to be displaced by the pulling, compressing, and rotating forces generated between the panel bodies 1 and 1, and an integral and strong joining state can be obtained. Further, even when a repeated load is applied between the panel bodies 1 and 1,
Since the effect of the repetitive load on the bolts 21 is extremely small, it is possible to prevent the bolts 21 from being loosened.

As described above, since the long side frames 5, 5 can be joined in an integrated joint state, the bolts 21 for fastening the joints 5b, 5b to the connecting plates 11, 12 are not limited to the high tension bolts. Even when a bolt is used, it is possible to obtain the same rigid joint as when a high-tensile bolt is used.

As a result, the joints 5b of the long side frames 5, 5
5b is not required to have extremely high rigidity as compared with the case of using a high tension bolt. Therefore, it is not necessary to use the long side frames 5, 5 as solid members, and the long side frames 5, 5 are easily extruded. And the manufacturing cost can be reduced. In addition, since the surface finishing of the front and back surfaces of the joints 5b and 5b and the management at the time of construction can be simplified, manufacturing and construction can be performed more easily than in the past. In addition, since the panel body 1 is joined by fastening bolts, it is also possible to easily replace and extend the panel body 1 partially.

Further, in the present embodiment, FIG.
As shown in (1), it is easy to form the roof main body 40 by gently curving it in the longitudinal direction. As shown in FIG.
The portions of the connecting plates 11 and 12 corresponding to the gaps between the joints 5b and 5b are bent at the same desired angle R, and the long side frames 5 and 5 are formed using the connecting plates 11 and 12. By joining, the adjacent panel bodies 1, 1
They can be joined so as to form an angle R therebetween. By joining the other panel bodies at a desired angle, the roof main body 40 can have a desired curved shape as well as a flat surface.

Further, the plurality of panel bodies 1 constituting the roof main body 40 are firmly connected, and since these panel bodies 1 themselves also serve as structural materials, the roof 40 supports each panel body 1. There is no need to provide structural materials such as beams. For this reason, it is possible to reduce the amount of the structural material used, and it is possible to construct a well-designed roof having a clear feeling without giving a pedestrian a troublesome feeling.

In this embodiment, the case where the panel joint structure is applied to the roof has been described. However, it is needless to say that the present invention can be applied to an outer wall and the like.

[0030]

As described above, according to the present invention,
When fastening the joint pieces of the panel body with bolts via the connecting plate, even if bolts other than high tension bolts are used,
The panel bodies can be firmly joined to each other by the same rigid joining as when a high-tensile bolt is used. Therefore, the joining piece and the connecting plate can be easily and inexpensively manufactured, and the management at the time of construction can be easily performed.
