Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a bracket for a guard pipe.

[Conventional technology]

Conventionally, a bracket 1 for fixing a beam to a guard pipe support is made of a flat steel plate folded in two, as shown in FIG. To fix the beam 3 to the column 2 by means of the bracket 1, the end of the beam 3 is inserted into the bracket 1 and fixed with the bolt 4.

[Problem that the invention attempts to solve]

However, the conventional bracket described above has the following problems. That is, the conventional bracket 1 is
Since the guard pipe can only rotate in a vertical plane parallel to the support 2 around the attachment point to the support 2, there is no problem when installing the guard pipe in a straight line on a single slope or horizontal plane. When installing a guard pipe at a point where the slope changes (at the top of a mountain), it is necessary to install two supports 2 as a set, as shown in Figure 7, which reduces the increase in the construction cost of the guard pipe. Not only is it inviting, but it also looks bad. These problems also occur when the guard pipe is installed in a curved manner in a horizontal plane.

The purpose of this idea is that even if the guard pipe is installed at a change in slope or curved in a horizontal plane, the end of the beam can be attached to a single support in the same way as in normal cases. The purpose of the present invention is to provide a bracket for guard pipes.

[Means for solving problems]

This idea consists of two opposing parts with bolt holes formed by bending a flat plate into a U-shape.
It is characterized in that it consists of a pair of beam clamping pieces and a fixing piece having a bolt hole, which is formed between the bent side bases of the pair of beam clamping pieces and protrudes from the base.

Next, a guard pipe bracket according to an embodiment of this invention will be explained with reference to the drawings.

FIG. 1 is a plan view showing a guard pipe bracket according to an embodiment of the invention, FIG. 2 is a side view of the same, and FIG. 3 is a front view of the same.

As shown in FIGS. 1 to 3, the guard pipe bracket 5 of this invention includes a pair of opposing beam clamping pieces 6 formed by bending a flat plate into a U-shape, and a pair of beam clamping pieces 6. It consists of a fixing piece 7 formed between the bent side bases of the piece 6 and protruding from the base.

Each of the pair of beam clamping pieces 6 is formed with a bolt hole 8 for a bolt to be inserted through the end of the beam 3. A bolt hole 9 for a bolt to be inserted into the support column 2 is formed in the fixing piece 7.

[Effect]

To attach a beam to a support using the guard pipe bracket of this invention constructed as described above, two brackets 5 are used, as shown in FIG. 4. Each bracket 5 is fixed to the column 2 by a bolt 10, and the beam 3 is fixed to the bracket 5 by a bolt 11.

Each bracket 5 rotates freely around a bolt 10 in a vertical plane parallel to the column 2, and the beam 3 attached to each bracket 5 is rotated around a bolt 11.
Rotate freely in the horizontal plane around . In this way, the beam 3 passes through the bracket 5 horizontally,
It can be rotated in any vertical direction. Therefore, not only when installing a guard pipe in a straight line in a horizontal plane or on a single slope, but also when installing a guard pipe at a change point of a slope or in a curved manner in a horizontal plane, the conventional Unlike a bracket, there is no need to use a set of two supports, and only one support is required.

In addition, the bracket 5, as shown in FIG.
The fixing piece 7' may be bent at a right angle.

[Effect of idea]

As explained above, according to this invention, the beam can freely rotate relative to the support even when the guard pipe is installed at a point where the slope changes or when it is installed curved in a horizontal plane. Therefore, a very useful effect is brought about in that the end of the beam can be fixed by one support.
