BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam pipe mounting structure for mounting a beam pipe on a pillar in an inclined fence having a beam pipe mounted on a pillar via a bracket.

[0002]

2. Description of the Related Art In a sloping ground fence having a beam pipe (a crosspiece using a pipe) attached to a support via a bracket, the beam pipe needs to be provided in parallel with the sloping ground. It is desired to be able to be attached to the support at an arbitrary angle corresponding to the above. FIGS. 7 and 8 show a beam pipe mounting structure of this kind (see Japanese Utility Model Publication No. 4-31293). This beam pipe mounting structure has a joining end face 3 having an arc shape in a vertical direction and a horizontal direction on a cylindrical portion 2 into which a beam pipe 1 is fitted.
A bracket 6 having a horizontally long hole 4 formed in the joint end face 3 and a vertically long hole 5 for joint formed in an upper surface of the cylindrical portion 2.
The bracket 6 is disposed on both sides of the column 7 with its joint end surface 3 against the column 7, and the curved surface 8
a and 9a, respectively, are fastened and fixed to the column 7 with bolts 8 and nuts 9, and the beam pipe 1 is attached to each bracket 6.
And the beam pipe 1 is fixed to the bracket 6 with bolts 10 and nuts 11 penetrating vertically.

[0003]

According to the beam pipe mounting structure having the above-described structure, the beam pipe 1 can be mounted on the column 7 at an arbitrary inclination corresponding to the angle of the slope. However, since the joint end face 3 of the bracket 6 has an arc shape in the vertical and horizontal directions, the bracket 6 comes into line contact with the column 7 and there is a problem that a sufficiently stable connection cannot be obtained. The beam pipe 1 is connected to the bracket 6
Since the bolts 10 and the nuts 11 to be fixed are exposed, the appearance is not good. Furthermore, since the bolts 8 and nuts 9 for fixing the bracket 6 to the column 7 cannot be tightened with a spanner when the beam pipe 1 is fitted to the bracket 6, the beam pipe 1 is fitted to the bracket 6. It is necessary to perform final tightening and fixing before
It is not always easy to fix the bracket 6 so that the angle of the bracket 6 is correctly adjusted to the angle of the sloping ground.

The present invention has been made to solve the above-mentioned conventional drawbacks, and can stably attach a beam pipe to a support, is excellent in aesthetic appearance, and can correctly adjust a bracket to an angle of an inclined ground. An object is to provide an easy beam pipe mounting structure.

[0005]

The beam pipe mounting structure according to the present invention for solving the above-mentioned problems has a cylindrical support contact surface in contact with the outer periphery of a support having a cylindrical cross section and a spherical back surface behind the support. A spacing member that contacts the column at the position of the bolt insertion hole, a mounting portion having a spherical contact surface that slidably contacts the spherical back surface of the spacing member, and a cylindrical surface provided with an opening for inserting a spanner. And a bracket integrally having a beam pipe fitting portion for fitting and supporting the beam pipe, and the spacing member and the bracket are passed through the vertically elongated bolt insertion holes and the bolt insertion holes of the columns respectively. A mounting bolt for tightening and fixing the column, a decorative pipe for covering the beam pipe fitting portion from the outer periphery of the beam pipe fitted to the beam pipe fitting portion of the bracket, and a screw penetrating the decorative pipe. Characterized by comprising a screw for fixing the decorative pipe and beam pipe is screwed into a threaded hole formed in the bracket through a screw insertion hole formed in the beam pipe bracket with.

According to a second aspect of the present invention, in the beam pipe mounting structure of the first aspect, a vertical projection is formed on the spherical back surface of the spacer, and a vertical groove for fitting the projection is formed on the spherical surface of the bracket. It is characterized in that it is formed on the contact surface.

According to a third aspect of the present invention, in the beam pipe mounting structure of the first aspect, a cylindrical rear surface is used instead of the spherical rear surface of the spacer, and a cylindrical contact surface is used instead of the spherical contact surface of the mounting portion of the bracket. It is characterized by.

[0008]

In the above construction, since the bracket comes into contact with the spacing member by the spherical surface, the bracket can have an arbitrary angle in the vertical and horizontal directions.

Since the spacing member contacts the column at the cylindrical column contact surface, it is stably fixed to the column. In addition, since the bracket and the spacer are in contact with each other through surface contact by the spherical surface, the bracket is stably coupled to the spacer. Therefore, the beam pipe is stably attached to the column.

Since the decorative pipe covers the end of the beam pipe and the fitting portion of the beam pipe of the bracket, and covers the mounting bolts for fixing the bracket to the column, the decorative pipe is good in appearance. In addition, by using a countersunk screw or the like as a screw for fixing the decorative pipe and the beam pipe to the bracket, it is possible to obtain a good appearance with no protrusion.

The mounting bolt for fixing the bracket to the support can be operated by inserting a wrench from the opening for inserting a wrench by shifting the decorative pipe, so that the beam pipe is fitted to the bracket according to the angle of the slope. In this state, final fastening and fixing of the mounting bolt can be performed. In this case, after that, a decorative pipe is covered and fixed with screws. Therefore, it is easy to correctly fix the bracket to the angle of the sloped ground.

The second aspect of the present invention is applied to a case where there is no need to bend the beam pipe in the horizontal direction because the road is not bent, and the vertical projection of the spherical back surface of the spacer and the vertical direction of the bracket side. By fitting into the groove, the bracket is restrained so as to rotate only in the vertical direction, and the stability of the beam pipe can be further improved when there is no need to make an angle in the horizontal direction.

A third aspect of the present invention is also applicable to a case where it is not necessary to make an angle in the horizontal direction of the beam pipe. Since the sliding surface between the bracket and the spacing member is a cylindrical surface, the bracket rotates only in the vertical direction. The beam pipe is stably attached to the column.

Further, the beam pipe fitting portion 29 has a shape in which a part of a cylinder is cut out, and a largely cut out portion is the opening 29a for inserting the wrench. The beam pipe fitting portion 29 has a screw hole 29b for screwing a countersunk screw 30 for fixing the beam pipe.

In the vicinity of the end of the beam pipe 22, a screw insertion hole 2 long in the longitudinal direction of the beam pipe through which the flathead screw 30 is passed.
In the decorative pipe 27, a screw insertion hole 27a having a conical seat for receiving the head of the countersunk screw 30 is formed.

Next, the operation of mounting the beam pipe in the above-described beam pipe mounting structure will be described. First, the pillars 21 are erected at predetermined intervals on the slope where the fence for the slope is to be installed. Next, the spacers 24 are applied to the columns 21 at the positions of the bolt insertion holes 21a on both sides of the columns 21 with the spacers 24 fitted on the spherical contact surfaces 28a of the mounting portions 28 of the brackets 23, respectively. Next, the mounting bolt 25 is inserted into the bolt insertion hole 28c of the bracket 23,
The nut 2 is inserted through the bolt insertion hole 24c of the spacing member 24 and the bolt insertion hole 21a of the support column 21.
Screw 6 in and tighten lightly with a spanner.

Next, the beam pipe 22 previously covered with the decorative pipe 27 is connected to, for example, the bracket 2 on the lower column 21 side.
3 is fitted to the beam pipe fitting portion 29. in this case,
As shown in FIG. 4, when the beam pipe 22 is slid in the direction of the solid line arrow and inserted into the vicinity of the inner part of the beam pipe fitting part 29 (until it approaches the mounting part 28), the beam pipe 22 and the upper column 21 Since a gap is formed between the bracket 23 and the core of the bracket 23, the beam pipe 2
The beam pipe 22 can be fitted to the upper and lower brackets 23 by aligning the two cores and sliding upward as indicated by the dashed arrow. In this state where the beam pipes 22 are fitted to the brackets 23 of the upper and lower columns 21, the beam pipes 22 are parallel to the surface of the sloped ground, and the angle of the brackets 23 is correctly adjusted to the angle of the sloped ground. The bolt insertion hole 28c of the bracket 23
Is vertically long, it does not interfere with the mounting bolts 25 even when the bracket 23 is tilted within a certain range, and since the bolt insertion hole 24c of the spacing member 24 is also vertically long, the spacing member 24 can be moved up and down. The brackets 23 on both sides of the support 21 can be fixed to the support 21 with a common mounting bolt 25.

Next, the decorative pipe 27 is shifted toward the center of the beam pipe to open the opening 29a for inserting a wrench, and a wrench is inserted through the opening 29a to operate the head of the mounting bolt 25 and the nut 26 to finally make it. Firmly. As described above, after the angle of the bracket 23 is correctly set, the bracket 23 can be finally tightened and fixed to the support column 21, so that there is no trouble in setting the angle of the bracket 23 correctly. Subsequently, the decorative pipe 27 is slid until it hits the mounting part 28 of the bracket 23 to cover the entire beam pipe fitting part 29, and then the flathead screw 30 is screwed into the screw insertion hole 27 a of the decorative pipe 27.
It is screwed into the screw hole 29b of the bracket 23 through the screw insertion hole 22a of the beam pipe 22. Thus, the decorative pipe 27 and the beam pipe 22 are fixed to the bracket 23. The external appearance of this beam pipe mounting structure is a flathead screw 3
0 does not protrude from the outer peripheral surface of the decorative pipe 27,
Most of the appearance is only a part of the spacing member 24 on the side of the support 21 with the decorative pipe 27, and the appearance is very simple, and the appearance is good.

In the above-described embodiment, the protrusion 24d and the groove 2 are fitted to the spacer 24 and the bracket 23.
8d is formed because it is applied to a fence for sloping ground that is installed only on a slope without a bend on the road, and it is necessary to attach the beam pipe 22 to the column at an angle also in the horizontal direction. In this case, the protrusion 24d and the groove 28d are not provided. Thus, the beam pipe can have an arbitrary angle not only in the vertical direction but also in the horizontal direction.

If the beam pipe does not need to be angled in the left and right direction, the inclined fence of the embodiment shown in FIGS. The rear surface may be a cylindrical contact surface instead of the spherical contact surface 28a of the mounting portion 28 of the bracket 23. 5 and 6 show the bracket 2 in this case.

a and a cylindrical seat 28'b, and the spacer 24 'has a cylindrical rear surface 24'b. In this case, there is no need for the protruding shape on the spacing member side and the groove on the bracket side to be fitted together. Other parts are almost the same as those in the embodiment of FIGS. The front vertical cross-sectional view of the bracket 23 'appears almost in the same manner as FIG.

[0023]

According to the present invention, since the bracket supporting the beam pipe and the spacing member stably held on the column side are connected to each other by surface contact with a spherical surface, the beam pipe is stably connected to the column. Is done. Further, the beam pipe can have an arbitrary angle in the vertical and horizontal directions.

Since the decorative pipe is covered over the beam pipe to cover the beam pipe fitting portion of the bracket, mounting bolts for fixing the bracket to the support are not exposed, and the bracket itself is hardly exposed. Aesthetically good. In addition, since the beam pipe is fixed to the bracket with screws together with the decorative pipe overlaid on the beam pipe, the screws can not be exposed at all, such as by using countersunk screws, which is also aesthetically pleasing. .

The mounting bolt for fixing the bracket to the column can be operated by inserting the spanner through the spanner insertion opening by shifting the decorative pipe toward the center of the beam pipe even after the beam pipe is fitted to the bracket. Therefore, the final tightening and fixing of the mounting bolts can be performed in a state where the beam pipe is fitted to the bracket, and the operation of correctly fixing the bracket to the angle of the sloping ground is easy.

According to the second aspect of the present invention, the bracket is restrained so as to rotate only in the vertical direction by fitting the protrusion on the spacing member side with the groove on the bracket side. When there is no need to make an angle in the horizontal direction, the connection between the beam pipe and the column can be further stabilized.

According to the third aspect, since the sliding surface between the bracket and the spacing member is a cylindrical surface, the bracket is restrained so as to rotate only in the vertical direction. When there is no need to make a horizontal angle of the beam pipe, the connection between the beam pipe and the support can be stabilized.
