Description

[Detailed Description of the Invention] The present invention relates to a side rail mounting bracket for a protective fence installed on a road or the like.

Conventional protective fences have a plurality of posts erected at appropriate intervals, and crossbars are fixedly attached to each post in a fixed direction via mounting brackets. However, such a guard fence has a structure in which the mounting bracket allows the side beam to be attached only in a certain direction relative to the support, so if the protective fence is installed at a curved point, sloped point, etc., the direction in which the side beam is installed is fixed. Because of the change in size, it was necessary to modify the mounting brackets and crossbars, and to prepare separate mounting brackets to match the installation location, which was an inconvenient drawback.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and as a result of intensive efforts, it is an object of the present invention to provide a side rail mounting fitting for a protective fence that eliminates the above-mentioned drawbacks.

The present invention will be described below with reference to the drawings.

In the drawings, A is the mounting bracket of the present invention,
It is formed from at least a pair of clamping plate parts 1, 1 and a connecting plate part 2.

The clamping plate parts 1, 1 are formed into oblong flat plates, are opposed in parallel, and are connected to each other by a connecting plate part 2 at approximately the center of one long side edge of the clamping plate parts 1, 1. There is. In addition, horizontal mounting holes 3, 3... are formed at both ends along the length direction of the clamping plate parts 1, 1, respectively, and at approximately the center of the connecting plate part 2 and at least one of the clamping plate parts 1. Pillar mounting holes 4, 4 are drilled in the respective portions. It is preferable that the cross-piece mounting holes 3, 3, . . . be elongated holes that extend in the length direction of the clamping plate parts 1, 1, since this allows flexibility when attaching the cross-pieces 7, which will be described later.

The mounting bracket A of the present invention may be formed into a substantially U-shape simply by the clamping plates 1, 1 and the connecting plate 2, but
Normally, as shown in FIGS. 1 and 2, plate pieces 5, 5 are extended approximately at the center of the other long side edge of the clamping plate parts 1, 1 so as to face the connecting plate part 2, respectively. This first ~
In the case of Fig. 2, when installing the crossbar 7, which will be described later, you can tighten the mounting bracket A to firmly fix it.
This is preferable because the mounting portion of the mounting bracket A to the support column 6 can be covered.

Next, the use of the mounting bracket A of the present invention will be described.

First, in the case of Fig. 3, the connecting plate part 2 of the mounting bracket A
The bolt 8 is in contact with the post 6 of the protective fence of the post 6,
The mounting bracket A is fixed by penetrating through the column attachment hole 4 of the connecting plate part 2, and is attached to the column 6 with the clamping plates 1, 1 facing each other vertically. Insert the ends of adjacent side rails 7, 7 of the protective fence between the sandwiching plate parts 1, 1, and insert the side rail mounting holes 3, 3... of the sandwiching plate parts 1, 1, and the horizontal rails 7, 7,
Attach the horizontal beams 7, 7 to the ends of the rods 7 by passing bolts 9, 9 through them. At this time, the horizontal legs 7, 7 may be appropriately rotated in the horizontal direction about the bolts 9, 9 as shown in FIG. 3A to mount the horizontal legs 7, 7 in a desired direction. In the case of this figure 3, the protective fence is installed at a curved point on the road, or the protective fence is installed not in a straight line but in a bent position, and of course, when the protective fence is installed normally in a straight line. It also applies to

Next, in the case of Fig. 4, one clamping plate part 1 of the mounting bracket A is brought into contact with the pillar 6 of the protective fence, and the bolt 8 is passed through the pillar 6 and the pillar mounting hole 4 of the clamping plate part 1. The mounting bracket A is attached to the support column 6 with the clamping plates 1 and 1 facing each other in the horizontal direction. The ends of adjacent side rails 7, 7 of the protective fence are attached between the clamping plate parts 1, 1 with bolts 9, 9, as in the case of FIG. At this time, the horizontal legs 7, 7 may be appropriately rotated in the vertical direction about the bolts 9, 9 as shown in FIG. 4 (b) to be mounted in a desired direction. In this case, the protective fence is installed at a sloped point on the road, and of course, it is also applicable to the case where the protective fence is normally installed in a straight line.

As described in detail above, in the mounting bracket of the present invention, the substantially central part of one long side edge of the oblong clamping plates facing in parallel is connected by the connecting plate part and at least one of the connecting plate parts. Since the support mounting hole is drilled in the clamping plate part of the protective fence, depending on the installation location of the protective fence, by attaching the connecting plate part or the clamping plate part to the pillar and attaching it, the clamping plate part can be installed horizontally or In correspondence with the vertical direction, a crossbeam can be mounted between them so as to be rotatable in the horizontal or vertical direction. That is, it is possible to easily cope with the installation location such as a curved point or a sloped point of the road by changing the mounting direction to the support using only one type of metal fitting, and it is possible to improve the workability of the protective fence. Furthermore, since the protective fence can be constructed using only one type of metal fittings, inventory management of the metal fittings can be easily managed and costs can be reduced.
