DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket device to be mounted on an inclined wall surface of a structure, and more particularly to a bracket device for an inclined wall surface which can easily adjust the angle of a bracket and has a large supporting force. .

[0002]

2. Description of the Related Art Conventionally, the above-mentioned bracket device has been used to support a rack, a trough, etc. for storing wiring and piping materials on an inclined wall surface of a structure. As one of the bracket devices, Japanese Utility Model Laid-Open No. 4-86
No. 041 is disclosed in Japanese Patent Application Laid-Open No. H07-171, filed on Oct. 24, 1993. "The bracket P is connected to the mounting bracket 1 with the connecting bolt 2 to form an arc-shaped slide adjustment hole 1C provided in the mounting bracket 1.
With the fixing bolt 4 penetrating through the bracket P,
A configuration in which the mounting bracket 1 and the bracket P are fixed so that their fixing positions are adjustable. Therefore, by adjusting the fixing position of the fixing bolt along the slide adjustment hole, the angle of the bracket with respect to the mounting bracket can be adjusted, and the bracket can be fixed horizontally to the inclined wall surface.

However, in this structure, since the inclination of the bracket with respect to the mounting bracket is maintained only by the fixing force of the fixing bolt, when the load applied to the bracket increases or the inclination angle of the bracket with respect to the mounting bracket increases. However, there is a problem that the fixing bolt moves along the slide adjustment hole, and the bracket cannot be kept horizontal.
In order to solve this problem, a pressing bolt screwed from the back side of the mounting bracket is pressed against the bracket to increase the fixing strength between the mounting bracket and the bracket, but this pressing bolt is applied to the bracket. Since a tensile force or a projecting force (compressive force) does not act on the pressure contact bolt due to the load, the angle of the bracket cannot be maintained when the load increases.

Further, as another conventional bracket device,
Japanese Unexamined Utility Model Application Publication No. 4-2931, Japanese Unexamined Patent Application Publication No. 7-245589, and Japanese Unexamined Patent Application Publication No. 7-245860 have a structure which is substantially the same as the above structure and is mounted on a wall surface. An arc-shaped long hole is formed in one of the body and a bracket connected to the attachment body via a connection bolt, and a bolt and a nut are inserted into the long hole and penetrate both. Thus, the bracket is maintained at a predetermined angle with respect to the mounting body, and the two are fixed to each other. Therefore, there is a problem similar to the above.

On the other hand, Japanese Utility Model Publication No. 7-22987 discloses that "an arc-shaped slide adjusting hole 2 is formed in a mounting bracket 1 and a fixing piece 5 provided on a free end side of the mounting bracket 1 is provided with a fixing bolt. A nut 4B screwed to one end of the fixing bolt 4 is engaged, and a slide bolt 3 provided orthogonal to the other end of the fixing bolt 4 is inserted through the slide adjusting hole 2 through the bracket P. Thus, there is disclosed a bracket device having a configuration in which the two bolts 1 and P are connected and fixed by the slide bolt 3 to maintain the angle of inclination of the bracket P with respect to the mounting bracket 1.

The above-mentioned bracket device has an advantage that the angle of inclination of the bracket P can be maintained. However, since the slide adjusting hole 2 provided in the mounting bracket 1 has an arc shape, the fixing bolt 4 and the fixing bolt 4 are changed depending on the angle of inclination of the bracket P. The crossing angle with the fixed piece 5 changes. For this reason, the nut 4B for adjusting the inclination comes into contact with the fixing piece 5 while being inclined, and it is difficult to rotate the nut 4B with respect to the fixing bolt 4 for adjusting the inclination angle of the bracket P. Also, fixing bolt 4
However, not only the tensile force in the axial direction but also the bending force are applied, so that the supporting force is weakened.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bracket device for an inclined wall surface which can easily adjust the inclination angle of the bracket with respect to the mounting body and has a large supporting force.

[0008]

In order to solve the above-mentioned problem, the present invention adopts a method in which a linear inclination adjusting hole is provided along a substantially horizontal direction, and the inclination adjusting hole extends along an extension line of the inclination adjusting hole. A mounting plate which is provided with a projecting plate portion orthogonal to the tilt adjusting hole and is mounted on the inclined wall surface of the structure; a bracket rotatably connected to the mounting body via a connecting bolt; The engaging portion at one end is inserted into the inclination adjusting hole of the mounting body and engaged with the bracket, and the bolt portion at the other end is formed in a bolt hole provided in the protruding plate portion. Inserted, the entire surface of the adjustment nut
Is in contact with the projecting plate portion of the mounting body, and the bolt portion is
The adjustment nut is screwed into the bracket, and slides linearly along the tilt adjustment hole to vertically displace the engagement position with respect to the bracket so that the tilt angle of the bracket with respect to the mounting body can be adjusted. The tilt adjusting bolt is used to form a bracket device, and the tilt angle of the bracket can be adjusted by linearly sliding the tilt adjusting bolt along the tilt adjusting hole.

When the adjusting nut is rotated with respect to the tilt adjusting bolt, the engagement position of the tilt adjusting bolt with respect to the bracket is changed along the vertical direction, and the tilt adjusting bolt is moved along the linear tilt adjusting hole. Slide,
The bracket rotates with respect to the mounting body around the connection bolt, and the inclination angle of the bracket with respect to the mounting body is changed. As described above, even if the inclination angle of the bracket with respect to the mounting body is changed, the inclination adjustment bolt only slides along the linear inclination adjustment hole, and the inclination adjustment is performed.
Since the entire surface of the adjusting nut is always in contact with the projecting plate portion provided on the mounting body orthogonal to the hole adjusting hole, the angle adjustment of the bracket performed by rotating the adjusting nut becomes easy,
The supporting state of the load acting on the bracket is stabilized, and the supporting force increases.
