Description

Protective barrier against falls of stones

The present invention relates to an improved rockfall prevention device having a rotary lower blocking plate, and more particularly, to quickly remove the earth and rock falling down by opening the blocking plate without the hassle of dismantling or detaching the bolt. It is about improved fall prevention measures to make it possible.

1 is a combined perspective view of the rockfall prevention measures according to the conventional embodiment disclosed in the Korean Utility Model 2000-017264, the following is a look at the rockfall prevention measures disclosed in the domestic Utility Model 2000-017264.

As shown in FIG. 1, the conventional rockfall prevention measures include a bracket 4 welded to the upper and lower edges of the rock bottom preventer 1 at the front inner side of the bottom of the frame 2, respectively, and on both sides of the blocking plate 3. Four corners are installed so that the ruler 5 caught by the bracket 4 is rotatable. The bracket 4 attached to the frame 2 has a ruler locking part formed at the front thereof, and a support portion supporting the rear surface of the blocking plate 3 is formed at the rear thereof, and the ruler 5 has a blocking plate ( It is inserted into the through hole 7 in the fixing bracket 6 welded to the four corners of both sides of 3), so that it is rotatable in place and can be moved forward and backward of the through hole 7. The tip of the ruler 5 has an L-shaped bent portion, and the bent portion can be ruled and unlocked by the rotational operation of the ruler locking part of the bracket 4 welded to the frame 2, and the rear end thereof. There is a hexagonal or square head is formed so that it can be easily rotated using a spanner or various tools. In addition, the ruler fastening jaw is formed horizontally inside the ruler locking part of the bracket 4, so that the bent part of the ruler 5 is caught in the horizontal state while being inserted into the ruler locking part inside. In the bracket 4 welded to the lower part of the frame 2, a lower jaw is formed in the lower side of the rear support part so that the lower end of the blocking plate 3 is horizontally positioned so that the blocking plate 3 is placed.

In addition, the blocking plate 3, as shown in the figure, the horizontal bar and the vertical bar is formed in a lattice-shaped frame, it is produced by fixing or welding the ridge mesh or welded wire mesh inside the frame, and bending the iron plate instead of the mesh It can also be attached to the mold.

Such a conventional rockfall prevention measure is a detachable type that must be lifted upward to separate the blocking plate (3), which is cumbersome to separate and combine, and takes more people than the rotary type when detaching and moving due to the weight of the blocking plate. And, the configured accessories are very complicated, there was a problem that takes a lot of time to install.

Figure 2 is a perspective view of the combined fall prevention measures according to another embodiment of the prior art, which is disclosed in Korean Utility Model 2000-017633.

In the conventional rockfall prevention measures, the frame is installed at a predetermined interval on the side of the mountain road, and the wire mesh is installed on the frame, so that the flanges 110 on both sides to constitute a preventive measure that prevents the falling of the rockfall and Sato to the road side. The wire frame 200 is installed on the formed frame 100 at a predetermined distance from the ground, and the barrier plate 300 is detachably attached to the flanges 110 of both frames 100 from the lower end portion of the wire mesh 200 to the ground. To be installed, but both sides of the upper end of the blocking plate 300 is provided with a ruler ball 310 is provided with a slide ruler, and the frame 100 is installed a ruler decoration 120 is inserted into the ruler interval, block plate ( On both sides of the lower end of the 300, a locking mechanism that is caught by the flange 110 of the frame 100 can be installed to be operated by the handle 320.

However, in the conventional rockfall prevention measures, since the blocking plate is attached to the outside of the flange, the blocking plate protrudes by the height of the web of the H-shaped frame than the upper rockfall prevention measure, and thus the upper and lower portions are not integrated, so It is not good, and since the connection between the H-shaped frame and the blocking plate is formed in a curved plate shape, it is very difficult to manufacture, and its structural strength is very weak so that it may be destroyed by frequent impacts of falling rocks. Vulnerability can be weakened further by the impact, and the upper and lower fixing devices are allowed to move left and right, respectively, because there is no clamping device of the fixing device when the impact of frequent falling rocks is applied to the blocking plate. However, there was a fear that the fixing device could be opened so that the blocking plate could not function properly. That is, the rockfall prevention measures should be able to sufficiently block the falling of the falling rocks, the conventional rockfall prevention measures had a very unstable problem in terms of structure. In addition, in the case of the removable rock removal work, there is a hassle of fastening and detaching when separating the blocking plate from the flange, and when only the lower part is opened by rotating, the blocking plate can be fixed in the open state. Since there is no special fixing device, there is a hassle in the work, and because of the impact of the rockfall removal work can be loosened because the coupling of the temporary rope or wire, there was a problem that the operator can feel anxiety.

Accordingly, the present invention is to solve the problems of the prior art as described above, for the strength side and convenience of operation, by installing a rotary blocking plate under the rockfall prevention fence, cumbersome work of separating and recombining the conventional blocking plate After the lower part is opened by rotating the blocking plate, it is possible to work by stably fixing the blocking plate to the flange, making the manufacturing of the blocking plate easier, and providing a rockfall prevention measure having a strongly stable structure. Its purpose is to.
