DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective fence installed in a seawall caisson or the like.

[0002]

2. Description of the Related Art For example, as shown in FIG. 5, when a plurality of caisson 1 are continuously installed to form a revetment and a protective fence is installed on the revetment, each caisson 1 may be settled unequally. In consideration of the above, the protective fence 2 is provided discontinuously independently of the adjacent caisson 1.

[0003]

Since the protective fence 2 is discontinuous, the landscape may be impaired. Therefore, as a means to cope with uneven settlement of caisson 1,
However, it is difficult to provide rails provided between columns that are erected at intervals in a continuous state, and the appearance is not good.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the prior art, and to flexibly cope with uneven settlement when arranging rail members between columns which are erected at intervals. It is to provide a protective fence that looks good by being continuous.

[0005]

According to the present invention, in order to achieve the above-mentioned object, a grid-like unit is formed by arranging standing pieces at intervals between upper and lower hollow rail materials, and the rail material of the grid-like unit is formed. At the end, the outer diameter of the base end is formed to be equal to the inner diameter of the rail material, the tip is formed to have a smaller diameter than this, and at the end, a joint is provided with a projection with an outer peripheral portion formed into a curved surface. The protrusion of the joint slides on the inner surface of the adjacent rail member on the side of the column, which is provided by inserting an end portion and is erected at an interval, and the protrusion and the base are provided between adjacent rail members. A gap is formed so that the small diameter portion between the ends is located, and the tip end of the joint is inserted into the adjacent rail material, or in addition to this configuration, the grid-like unit is attached to the rail material on the column side. The gist is that a stopper that prevents lateral movement is provided close to the joint. It is intended.

[0006]

According to the first aspect of the present invention, the joints protruding from both ends of the rail member are inserted into the adjacent rail members on the side of the column which is erected at an interval. Is formed into a curved surface, so that the joint and the rail material in contact with the joint are connected to each other so as to be able to roll.

Further, by forming a gap between adjacent rail members, rolling of the rail members is not hindered, and one rail member can be deviated from the other rail member.
It can cope with uneven settlement of pillars due to uneven settlement of caisson. Furthermore, since the protrusions are in sliding contact with the inner peripheral surfaces of the adjacent rail members, the connection can be performed without causing rattling.

[0008] In addition, by forming the protruding portion at the tip of the joint, the amount of deviation of the other rail member with respect to one rail member can be increased.

According to the second aspect of the present invention, in addition to the above-described operation, the joint abuts against the stopper, thereby restricting the amount of lateral movement of the lattice unit with respect to the rail member on the side of the support, thereby reducing the lattice unit. Can be held in place.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal sectional front view of a joint portion which is a main part showing an embodiment of a protective fence of the present invention, FIG.
FIG. 4 is a vertical sectional front view of a main part of the same, and FIG. 4 is a front view of the whole protective fence. FIG.

The protective fence 2 of the present invention is also installed, for example, over a plurality of caissons 1, 1... Installed in succession, and supports 3 are erected at equal intervals. A grid-like unit 6 formed by arranging standing members 5 by welding at intervals between the rail members 4, 4 is provided by welding the hollow rail members 4 to the columns 3. In this case, the upper hollow rail member 4 is a coping, the lower hollow rail member 4 is a cross beam, and for example, an aluminum alloy is used as the material including the column 3.

FIG. 1 shows a pillar 3 erected on an adjacent caisson 1.
FIG. 3 shows a structure of a joining portion between the upper rail member 4 which is the upper rail member 4 provided therethrough and the upper rail member 4 which is the upper rail member 4 of the lattice unit 6. Joints 7 protrude from both ends of the rail member 4 of the lattice unit 6.

As a protruding means, the end of the joint 7 is inserted into the hollow portion of the rail member 4 and is fixed from the bottom of the rail member 4 with screws 8 or the like as shown in FIG.

The joint 7 is formed of a shape or a casting, has a substantially cylindrical shape as a whole, and has an outer diameter of a base end portion 7a equal to an inner diameter of the rail member 4, and a tip end portion formed to have a smaller diameter. Then, a projection 7b having a curved outer peripheral portion was formed at the tip.

Then, the joint 7 is inserted into the hollow portion from the end opening of the adjacent rail member 4 that penetrates the column 3 erected at the end of the adjacent caisson 1. At this time, the joint 7 is inserted into the adjacent rail member 4 such that a gap 9 is formed between the adjacent rail member 4 and the rail member 4 to which the joint 7 is attached. The gap 9 is set to, for example, about 20 mm in consideration of expansion and contraction in the length direction due to a temperature difference. Then, in this state, the bottom of the protrusion 7 b of the joint 7 is in sliding contact with the bottom of the inner peripheral surface of the adjacent rail 4.

A stopper 10 for preventing lateral movement of the lattice-shaped unit 6 is provided on the rail member 4 on the side of the adjacent column 3 on which the joint 7 is inserted. This stopper 10
As shown in FIGS. 1 and 2, it is formed in a pin shape, and is provided in the column 3 so as to penetrate the rail member 4 vertically.

The lower rail member 4 is also connected to the adjacent lower rail member 4 attached to the column 3 erected at the end of the adjacent caisson 1 through the same joint 7 as described above. (Refer to FIG. 3), however, the stopper 10 does not necessarily need to be provided at the lower joint portion.

In order to attach the rail members 4 of the grid-like unit 6 between the columns 3 installed on the same caisson 1, as shown in FIG. For the rail material 4
Via 11 for the cross rail sleeve for the lower rail material 4
Each of them is connected and fixed with screws 8 via 12.

The protective fence 2 installed as described above over a plurality of adjacent caissons 1 has good appearance because the columns 3 are arranged at equal intervals and the rail members 4 are also continuous in the horizontal direction.

When only one of the adjacent caissons 1 is unequally settled, the protruding portion 7b formed at the distal end of the joint 7 is formed on the bottom of the adjacent rail material 4 at the hollow portion of the adjacent rail material 4 at the mutually connected portion. Sliding while contacting. At this time, since the gap 9 exists between the adjacent rail members 4, 4, the sliding of the rail member 4 is smoothly performed without being hindered.

As a result, one rail member 4 can be displaced with respect to the other rail member 4, and the caisson 1, that is, the column 3, can cope with uneven settlement. Even if the rail members 4 and 4 are displaced from each other, the projection 7b of the joint 7 is in sliding contact with the inner surface of the other rail member 4, so that the joints are connected without rattling.

Also, the expansion and contraction of the rail 4 in the longitudinal direction due to the temperature difference can be absorbed by the gap 9 provided between the rails 4.

The joint 7 provided on one of the rail members 4
Is moved laterally inside the other rail member 4, the stopper 10 is provided inside the other rail member 4, so that the tip of the joint 7 abuts the stopper 10 to restrict the amount of movement. Thereby, the lattice unit 6 can be restrained at a fixed position. Therefore, even if there is a gap, the finger is not pinched.

In the above-described embodiment, the connection between the rail member 4 and the upright 5 and the connection between the rail member 4 and the column 3 in the lattice unit 6 are performed by welding. However, the present invention is not limited to this. It is also possible to adopt a fastening system.

[0025]

As described above, the protective fence according to the present invention is not suitable for arranging rail members between columns that are erected at intervals over a plurality of adjacent caissons, for example. It can flexibly cope with the settlement, and has a good design appearance due to the continuous rail material.
