Further, the column-side mounting bracket 40 is provided with a bolt insertion hole 42 extending through the center portion thereof in and out. A connection bolt 50 composed of a head 44 and a leg 46 is inserted into the bolt insertion hole 42, and is mounted so as to protrude on the outer peripheral surface of the support-side mounting bracket 40.

The head 44 of the connecting bolt 50 has a surface on the side of the leg 46 formed as a spherical convex surface 48 having a curvature corresponding to the spherical inner peripheral surface 36 of the support-side mounting bracket 40. Further, the leg portion 46 is formed with an outer diameter smaller than the inner diameter of the bolt insertion hole 42 provided in the support side mounting bracket 40 by a predetermined dimension, and is loosely inserted into the bolt insertion hole 42 with a certain amount of play. ing. That is,
The connecting bolt 50 is configured such that its leg 46 can be displaced in the bolt insertion hole 42 so that the direction in which the connecting bolt 50 protrudes from the support-side mounting bracket 40 can be changed. Even when the projecting direction is changed in such a manner, the head 44 can be stably seated on the spherical inner peripheral surface 36 of the support-side mounting bracket 40 (see FIG. 4). See FIG. 8).

Further, a substantially annular or cylindrical contact fitting 54 is externally mounted on the leg 46 of the connecting bolt 50 inserted into the bolt insertion hole 42 of the support side mounting fitting 40. ing. One end surface of the contact fitting 54 in the axial direction is a spherical concave surface 52 having a curvature corresponding to the spherical outer peripheral surface 38 of the support-side mounting fitting 40. The leg 4 of the connecting bolt 50 is so positioned that the spherical concave surface 52 is brought into contact with the spherical outer peripheral surface 38 of the support-side mounting bracket 40.
6 is loosely inserted.

As described above, the contact fitting 54 externally inserted into the connecting bolt 50 is fastened by the fastening nut 56 screwed to the connecting bolt 50, and the spherical concave surface 52 of the contact fitting 54 is attached to the support-side mounting fitting 40. It is in contact with the spherical outer peripheral surface 38. That is, thereby, the column-side mounting bracket 40 is clamped and held between the head 44 of the connecting bolt 50 and the abutment metal 54, so that the connecting bolt 50 is connected to the column-side mounting bracket 50. It is fixed with respect to 40. In the figure, reference numeral 58 denotes a lock nut.

On the other hand, the leg 4 of the connecting bolt 50
A panel-side mounting bracket 60 is screwed to the distal end of 6. The panel-side mounting bracket 60 includes a rectangular flat mounting seat 62 and a rod portion 64 protruding from a central portion of the mounting seat 62 onto one surface. A screw hole 66 is provided on the distal end surface. In addition, the rod portion 64 is attached to the mounting seat 62.
The eaves 12 are erected at an angle corresponding to a predetermined inclination angle of the eaves 12 with respect to the support 32. Further, the mounting seat 62 is provided with four insertion holes 68, and is mounted on the eaves 12 as described above by the mounting bolts 74 inserted into the insertion holes 68. (See FIG. 9).

The distal end of the leg 46 of the connecting bolt 50 is screwed into the screw hole 66, so that the connecting bolt 50 is screwed to the panel-side mounting bracket 60. That is, thereby, the panel-side mounting bracket 60 is connected to the column-side mounting bracket 40, and thus the column 32, via the connection bolt 50. In the drawing, 70 is a tightening nut, and 72 is a lock nut.

Accordingly, in the supporting portion connecting mechanism 34 having such a structure, as shown in FIG. 8, the head 44 side of the connecting bolt 50 is inserted into the bolt insertion hole 42 of the support side mounting bracket 40. The support 3
The projection angle: θ of the connecting bolt 50 with respect to the connecting bolt 2 is variable.
By adjusting the amount of screwing of the panel-side mounting bracket 60 into the rod portion 64, the distance L between the column-side mounting bracket 40 and the panel-side mounting bracket 60 is made variable.

When the tip of the column 32 is attached and fixed to the lower surface of the eave 12 via the support connecting mechanism 34 as described above, the eave 12 is supported by the column 32 first. In each of the support connecting mechanisms 34 attached to the distal end of the support 32, θ and L are determined according to the design values, and the connecting bolts 50 are connected to the support side connecting fitting 40 and the panel side connecting fitting 60. Temporarily fix.

Next, the eaves 12 as described above are lifted by a crane, and placed on the mounting seats 62 of the support connecting mechanism 34 attached to the distal ends of the columns 32. Then, after roughly determining the positions of the six mounting seats 62 with respect to the eaves 12, the lock nuts 58, 72 and the tightening nuts 56, 70 of the support connecting mechanism 34 are loosened, and the position of the mounting seat 62 is finely adjusted. By doing so, each mounting seat 62
Is fixed to the eaves 12. In the present embodiment, each of these mounting seats 62 is
It will be fixed to the beam 30 provided on the eaves 12.

Among the fine adjustments for determining the fixing position of the mounting seat 62 with respect to the eaves 12, the adjustment of the mounting distance between the support 32 and the eaves 12 in the axial direction requires the use of the leg 46 of the connecting bolt 50. The mounting angle (solid angle) of the column 32 with respect to the eaves 12 is adjusted by screwing the rod portion 64 of the panel-side mounting bracket 60 into and out of the rod portion 64. This is performed by displacing in the bolt insertion hole 42 of the metal fitting 40. By such an adjustment, a three-dimensional displacement between the mounting portion between the tip of the column 32 and the eaves 12 can be absorbed.

After the fixing position of the mounting seat 62 with respect to the eaves 12 is determined in this manner, a female screw hole for fixing the mounting bolt 74 to the beam 30 (shapes 16 and 18) of the eaves 12 is formed. With reference to the insertion hole 68 provided in the mounting seat 62, the hole is formed through ordinary steps of drilling, tapping, and assembling a helisert. In this embodiment, the reinforcing members 78 and 80 are provided inside the profiles 16 and 18 before welding the beams 30 because the thickness of the profiles 16 and 18 constituting the beams 30 is insufficient. Was fixed by welding.

After the mounting bolts 74 are screwed into the female screw holes formed in the beam 30 as described above, the mounting seats 62 are fixed to the eaves 12. By tightening the lock nuts 58 and 72 to securely fix the connected state, the work of attaching the eaves 12 to the column 32 is completed as shown in FIG.

It is also possible to provide a protective sleeve or the like for covering the support portion connecting mechanism 34 at a position where the eaves 12 are attached to the column 32 by the support portion connecting mechanism 34, thereby providing a design effect. Is also improved.

Therefore, when the support connecting mechanism 34 as described above is used, the eaves 12 welded and joined in advance on the ground are attached to and supported by the columns 32 which are fixed upright in advance. Point: In a to f, a three-dimensional displacement caused by superposition of a dimensional error, a construction error, and the like caused between the eaves 12 and the column 32 can be easily absorbed by a simple adjustment operation. Yes, its workability can be dramatically improved.

Further, since the supporting portion connecting mechanism 34 has a simple structure in which the connecting portions are connected by a single connecting bolt 50, the supporting portion connecting mechanism 34 has an advantage that the manufacturing is easy and the construction cost is easy. is there.

As described above, at each supporting point, the supporting portion connecting mechanism 34 for supporting the eaves 12 with respect to the column 32 via one connecting bolt 50 allows the reference panel 2 constituting the eaves 12 to be supported. Is a brazed aluminum honeycomb panel, and its specific gravity is about 0.3, which is extremely light, and could be made feasible. With such a supporting portion connecting mechanism 34, a brazed aluminum honeycomb panel was formed. The effect that the characteristics of the panel can be exhibited even more advantageously and the application range thereof can be expanded can also be achieved.

Although the embodiment of the present invention has been described in detail, this is a literal example, and the present invention is not construed as being limited to such a specific example.

For example, in the above embodiment, a plurality of columns 3
2 are both erected in an inclined manner, but also in the case where an integrated panel such as an eave is attached to and supported by a plurality of columns which are erected vertically, the support portion connection according to the present invention is also possible. A structure can be advantageously applied.

In the above embodiment, the support 32 is
Although a steel pipe was used, its structure is not limited, and any structure such as a reinforced concrete column that can be attached to a support-side mounting bracket that constitutes a support portion coupling mechanism may be used.

Further, in the above-described embodiment, the panel-side mounting bracket 60 constituting the support portion connecting mechanism 34 is attached to the beam 30 of the eave 12, but the specific structure of the eave is as follows. It should be determined according to the required strength and the like, and is not limited thereto, and the mounting structure of the support portion connecting mechanism is also changed accordingly. For example, the panel-side mounting bracket of such a support portion coupling mechanism is directly or indirectly connected via a bracket or the like.
It is also possible to attach to the face plate of the brazed aluminum honeycomb panel constituting the integral panel.

Further, when adjusting the amount of screwing of the connecting bolt 50 into the panel-side mounting bracket 60, in order to facilitate the turning operation of the connecting bolt 50, the connecting bolt 50 is positioned at the axially intermediate portion. It is also effective to provide an operation unit or the like protruding outward in the direction perpendicular to the axis.

In addition, in the above-described embodiment, a specific example in which the present invention is applied to the support structure of the eaves is shown. However, other examples such as roofs and walls composed of brazed aluminum / honeycomb panels are provided. The present invention can be advantageously applied to various types of support structures for integral panels.

In addition, although not enumerated one by one, the present invention
Based on the knowledge of those skilled in the art, various changes, modifications, improvements and the like can be implemented in an embodiment,
It goes without saying that all such embodiments are included within the scope of the present invention, without departing from the spirit of the present invention.

[0040]

As is apparent from the above description, if the supporting portion connecting structure of the integral panel having the structure according to the present invention is adopted, a three-dimensional displacement error in the mounting portion of the support to the integral panel is reduced. The connection bolt can be absorbed by a very simple operation of positioning the mounting bracket on the column side in the bolt insertion hole and adjusting the amount of screwing of the mounting bracket on the panel side into the screw hole.

Accordingly, a large-area integrated panel composed of a brazed aluminum honeycomb panel can be hung on a plurality of columns that have been erected in advance and can be mounted and supported. Dramatic improvement in the workability of eaves, roofs, walls and the like can be achieved.
