Description
본 발명은 대단위 건축단지의 사면의 와이어로프의 교차지점에 설치되는 건축용 낙석방지 와이어로프 고정장치에 관한 것으로서, 특히 낙석방지망을 지지함과 동시에 암벽에 삽입된 락볼트에 체결되도록 함으로써 락볼트에 의해 사면의 보강효과가 향상되고, 낙석방지망에 의해 소규모의 낙석 뿐만 아니라 사면의 특정부분이 다량의 낙석이 발생하여 망에 많은 하중이 생김으로써 부분적으로 붕괴될 수 있는 것을 방지하도록 하는 장치에 관한 것이다.The present invention relates to a rockfall prevention wire rope fixing device for building installed at the intersection of the wire rope on the slope of a large-scale building complex, in particular by supporting the rockfall prevention net and by being fastened to the rock bolt inserted into the rock wall by the rock bolt The reinforcement effect of the slope is improved, and the apparatus for preventing the collapse of a small rockfall as well as a small part of the slope by the rockfall prevention net can be partially collapsed by a large amount of rockfalls generated by the load on the net.
일반적으로 대단위의 건축단지를 조성할때에는 평탄화 작업에 의해 절취 사면이 생성되는데, 이러한 절취 사면의 돌이나 흙이 이러한 낙석을 방지하기 위해 통상적으로 낙석방지망이나 락볼트가 사용되는 바, 상기 낙석방지망은 합성수지나 와이어 등을 그물 모양으로 제조하여 사면에 덮어씌우고 그 외측에 와이어를 종, 횡 방향으로 교차시켜 설치함으로써 소규모의 낙석을 방지하며, 상기 락볼트는 다수의 철재볼트를 일정 간격을 유지하면서 사면에 체결시킴으로써 사면의 보강효과를 향상시킨다.In general, when constructing a large-scale building complex, a cut slope is generated by a planarization operation. A rock or a bolt of a rock slope is usually used to prevent such falling rocks from stones or soil of the cut slope. Synthetic resin or wire is made in the shape of a net to cover the slope and installed on the outside by crossing the wire in the longitudinal and transverse directions to prevent small rockfall, the rock bolt slopes a number of steel bolts while maintaining a certain interval By tightening in, the reinforcement effect of the slope is improved.
그러나 종래의 낙석방지 와이어로프 고정장치가 장착된 구조를 도시한 설치상태도인 도1a와 종래의 낙석방지 와이어로프 고정장치를 도시한 사시도인 도 1b에 도시된 바와 같이, 종래기술에 의한 낙석방지망(100)의 고정부재(200)와 락볼트(201) 및 너트(202)는 각각 그 단점이 있는 바, 상기 낙석방지망은 외측에 설치되는 와이어로프(101)와 함께 사면의 일 측에 설치되는 고정부재(200)에 연결되도록 설치되기 때문에 사면에서 떨어지는 소규모의 낙석방지는 용이하나 사면 자체의 강도를 향상시키지는 못하므로 낙석이 크거나 그 양이 많을 때는 낙석방지망 또한 건축단지측으로 늘어지는 등, 그 체결력이 낮은 문제점이 있다.However, as shown in FIG. 1A, which is an installation state diagram showing a structure in which a conventional rockfall prevention wire rope fixing device is mounted, and FIG. 1B, which is a perspective view illustrating a conventional rockfall prevention wire rope fixing device, the rockfall prevention net according to the prior art ( The fixing member 200, the lock bolt 201 and the nut 202 of the 100 has its disadvantages, respectively, the rockfall prevention net is fixed to one side of the slope with the wire rope 101 is installed on the outside Since it is installed to be connected to the member 200, it is easy to prevent small rocks falling from the slope, but it does not improve the strength of the slope itself. Therefore, when the rock is large or the amount is large, the rockfall prevention network is also stretched toward the construction site side. There is this low problem.
또한 종래기술에 의한 락볼트는 사면에 직접 체결되어 사면의 강도, 즉 지지력을 향상시킴으로써 사면이 크게 무너지는 것을 방지할 수 있으나 다수의 락볼트를 사면에 고정한다고 하여도 사면의 특정부분에 다량의 낙석이 발생할 경우에는 그 부분에 많은 하중이 발생하여 망이 찢어지거나, 사면전체의 붕괴를 유발할 수도 있게 된다.In addition, the lock bolt according to the prior art can be directly fastened to the slope, thereby improving the strength of the slope, that is, the bearing force, thereby preventing the slope from being greatly collapsed. However, even if a plurality of lock bolts are fixed to the slope, When a rockfall occurs, a lot of load is generated on the part, which may cause the net to be torn or collapse of the entire slope.
따라서 본 발명은 이상의 문제점을 감안하여 창안한 것으로서, 사면의 특정부분에 다량의 낙석이 발생하여 그 특정부분에 많은 하중이 주어지지 않도록 와이어로프와 와이어로프를 결착하고 있는 회전판을 유동가능하게 구성된 건축용 낙석방지 와이어로프 고정장치를 제공하고자 한다.Accordingly, the present invention has been made in view of the above problems, and the construction is configured to be able to flow the rotating plate binding the wire rope and wire rope so that a large amount of rockfall occurs in a specific portion of the slope so that a large load is not given to the specific portion. To provide a rockfall prevention wire rope fixing device.

After the nut 15 is fastened to the screw fastening portion 141 by passing through the 113, 11a, and 103b, the rotating plate 13 can flow left and right.
한편, 상기의 구조로 구성된 본 발명은 사면의 특정부분에 많은 하중이 발생하여도 도5에서와 같이, 그 특정부위의 타부위에 장착되어 있는 와이어로프 고정장치에서 인장력을 제공해줌으로써 극단적으로 망이 찢어지거나, 고정장치가 사면으로부터 이탈되는 것을 방지할 수 있게 된다.On the other hand, the present invention composed of the above structure, even if a lot of load occurs in a specific portion of the slope, as shown in Figure 5, by providing a tensile force in the wire rope fixing device mounted on the other portion of the particular portion is extremely damaging It is possible to prevent tearing or detachment of the fixing device from the slope.
그리고 본 발명의 회전판(13)에는 와이어로프(101)가 와이어걸림부(131) 이외에도 다시한번 고정해줄 수 있는 걸림턱(132)을 형성 시킬 수도 있다.In addition, in the rotating plate 13 of the present invention, the wire rope 101 may be provided with a locking step 132 that can be fixed once again in addition to the wire locking portion 131.
즉, 상기 회전판(13)의 상부에는 한쌍의 걸림턱(132)이 부설되어 와이어로프(101)가 이탈되는 것을 방지할 수 있게 된다.That is, a pair of locking projections 132 are disposed on the upper portion of the rotating plate 13 to prevent the wire rope 101 from being separated.
그리고 본 발명에 따른 건축용 낙석방지 와이어로프 고정장치는 첨부된 도면 및 구체적인 실시 예와 관련하여 설명하였지만, 본 발명은 이에 의하여 특별히 제한되는 것은 아니며 본 발명의 기술적 사상의 범위 내에서 당해 분야의 당업자에 의하여 다양한 변형이 이루어질 수 있다.And the rockfall prevention wire rope fixing device according to the present invention has been described with reference to the accompanying drawings and specific embodiments, the present invention is not particularly limited thereby and to those skilled in the art within the scope of the technical spirit of the present invention. Various modifications can be made by the above.
이상과 같이 구성되고 작용되는 본 발명은 대단위 건축단지의 사면의 와이어로프의 교차지점에 설치되는 건축용 낙석방지 와이어로프 고정장치에 관한 것으로서, 특히 낙석방지망을 지지함과 동시에 암벽에 삽입된 락볼트에 체결되도록 함으로써 락볼트에 의해 사면의 보강효과가 향상되고, 낙석방지망에 의해 소규모의 낙석 뿐만 아니라 사면의 특정부분에 다량의 낙석이 발생하여 망에 많은 하중이 생김으로써 부분적으로 붕괴될 수 있는 것을 방지하는 효과가 있다.The present invention constituted and operated as described above relates to a rockfall prevention wire rope fixing device for building installed at the intersection of the wire rope of the slope of a large building complex, and in particular to the rock bolt inserted into the rock wall while supporting the rockfall prevention net. By tightening the lock bolt, the reinforcement effect of the slope is improved, and the rockfall prevention network prevents the small scale rockfall and the large amount of rockfall from the specific part of the slope, which can cause the load to collapse partially due to the large load on the mesh. It is effective.
