Description
본 발명은 소일 네일의 철근 설치 구조에 관한 것으로, 더욱 상세하게는 간편한 작업으로 철근을 제거할 수 있도록 한 소일 네일의 철근 설치 구조에 관한 것이다.The present invention relates to a reinforcing structure of reinforcing nails, and more particularly, to a reinforcing structure of reinforcing nails for removing reinforcing bars in a simple operation.
일반적으로, 지상에 건물을 건축하는 경우 지반의 붕괴를 방지하기 위한 기초 공사로 지반의 벽면에 네일을 설치하여 벽면의 흙이 무너지는 것을 막게 된다.In general, when building on the ground as a foundation for preventing the collapse of the ground to install the nail on the wall of the ground to prevent the soil on the wall collapse.
종래 기술에 따른 네일의 설치 구조를 간단히 설명하면 다음과 같다.Briefly, the installation structure of the nail according to the prior art is as follows.
지반의 벽에 구멍을 수평으로 뚫고, 이 구멍에 철근을 삽입함과 아울러, 모르타르,콘크리트 등을 주입하여 철근을 벽에 고착시키게 된다.Holes are drilled horizontally in the walls of the ground, rebar is inserted into the holes, and mortar and concrete are injected to fix the rebars to the wall.
그리고, 다른 방법으로 복수개의 소켓을 튜브로 연결하며, 이 통체의 내부에 철근을 삽입하여 네일을 제조하고, 네일을 벽에 천공된 구멍에 삽입, 모르타르 등을 주입하여 고착시킨다. 이때, 소켓의 내경과 철근의 외주면에는 각각 나사선이 형성되어 철근은 나사 체결된다.Then, a plurality of sockets are connected by a tube by another method, and a nail is manufactured by inserting reinforcing bars into the inside of the cylinder, and the nail is inserted into a hole drilled into the wall, and the mortar is injected and fixed. At this time, the inner diameter of the socket and the outer circumferential surface of the reinforcing bars are each formed with a screw thread is screwed to the rebar.

어댑터(50)는 반원형으로 이루어진 복수의 어댑터편(51)(52)으로 구성되며, 어댑터편(51)(52)의 내면에는 철근(10)의 외주면에 형성된 돌출부(11)가 끼워지는 고정홈(51a)(52a)이 형성되어 철근(10)에 대해 수직 방향으로 분리 가능하게 결합되는 한편, 외주면에는 나사부(51b)(52b)가 형성된다.The adapter 50 is composed of a plurality of adapter pieces 51 and 52 made of a semicircular shape, and the fixing groove into which the protrusion 11 formed on the outer circumferential surface of the reinforcing bar 10 is fitted on the inner surface of the adapter pieces 51 and 52. 51a and 52a are formed to be detachably coupled to the rebar 10 in the vertical direction, while threaded portions 51b and 52b are formed on the outer circumferential surface thereof.
아울러, 소켓(30)의 내면에는 나사부(30a)와 확경부(30b)가 연이어 형성되며, 어댑터(50)는 철근(10)과 일체화되면서 소켓(30)의 나사부(30a)에 나사 체결되고, 이때, 철근(10)을 여러번 돌리지 않아도 인출될 수 있고 어댑터편(51)(52)과소켓(30)의 각 나사부(51b)(52b)(30a)는 피치가 넓게 형성되는 것이 바람직하다.In addition, the threaded portion 30a and the enlarged diameter portion 30b are successively formed on the inner surface of the socket 30, and the adapter 50 is screwed to the threaded portion 30a of the socket 30 while being integrated with the reinforcing bar 10. At this time, the rebar 10 can be pulled out without turning several times, and it is preferable that the threaded portions 51b, 52b, 30a of the adapter pieces 51, 52 and the socket 30 have a wide pitch.
즉, 철근(10)은 어댑터(50)를 매개로 하여 소켓(30)의 내부에서 이동 가능하게 결합되는 것이다.That is, the reinforcing bar 10 is coupled to the inside of the socket 30 through the adapter 50 so as to be movable.
이와 같이 구성된 본 발명 소일 네일의 철근 설치 구조에 따른 작용 상태를 설명하면 다음과 같다.Referring to the operational state according to the reinforcing bar installation structure of the present invention configured soil nail as follows.
본 발명 네일(100)의 제조 공정을 설명하면, 철근(10)의 돌출부(11)와 어댑터편(51)(52)의 고정홈(51a)(52a)을 맞춰어 어댑터편(51)(52)을 철근(10)에 끼워 결합하고, 이어서, 어댑터편(51)(52)과 소켓(30)의 나사부(51b)(52b)(30a)를 맞물려 나사 체결하며, 소켓(30)의 선단부에 캡(60)을 조립한다.When explaining the manufacturing process of the nail 100 of the present invention, the adapter piece (51) (52) by matching the protrusion (11) of the reinforcing bar 10 and the fixing groove (51a) (52a) of the adapter piece (51) (52) ) Is coupled to the reinforcing bar 10, and then the screw pieces 51b, 52b, 30a of the adapter piece 51, 52 and the socket 30 are engaged with each other to be screwed together, and the tip of the socket 30 Assemble the cap 60.
계속해서, 소켓(30)의 후단부에는 방수링(61)을 개재하면서 튜브(40)를 끼워 조립하고, 그 다음 소켓(31)을 결합한다.Subsequently, a tube 40 is fitted to the rear end of the socket 30 via the waterproof ring 61, and then the socket 31 is engaged.
철근(10)에 어댑터(50)를 결합하고, 소켓(31)을 전술한 방법으로 어댑터(50)에 나사 체결하는 한편, 튜브(40)와 소켓(31)의 이음부에 연결구(62)와 방수링(63)을 결합한다.The adapter 50 is coupled to the reinforcing bar 10 and the socket 31 is screwed into the adapter 50 in the above-described manner, while the connector 62 and the joints of the tube 40 and the socket 31 are connected to each other. Combine the waterproof ring (63).
이러한 과정을 반복 수행하여 네일(100)을 제조하게 된다.By repeating this process, the nail 100 is manufactured.
제조된 네일(100)을 벽의 삽입공에 삽입하고, 모르타르 등을 주입하여 네일(100)을 벽에 정착시키며, 마지막으로 지압판(미도시) 및 공지의 결속구(64)를 설치함으로써 네일(100)의 설치가 완료된다.The manufactured nail 100 is inserted into the insertion hole of the wall, and mortar or the like is injected to fix the nail 100 on the wall, and finally, by installing a pressure plate (not shown) and a known binding port 64, the nail ( Installation of 100) is completed.
한편, 철근(10)을 제거를 위하여 철근(10)을 해제방향으로 회전시키면 철근(10)에 일체화된 어댑터편(51)(52)이 나사부(30a)(51b)(52b)의 안내를 받으며회전되면서 철근(10)이 통체(20) 즉, 벽으로부터 서서히 인출된다.Meanwhile, when the rebar 10 is rotated in the release direction to remove the rebar 10, the adapter pieces 51 and 52 integrated in the rebar 10 are guided by the screw portions 30a, 51b, and 52b. The rebar 10 is slowly drawn out from the cylinder 20, that is, the wall while being rotated.
철근(10)과 함께 어댑터편(51)(52)이 소켓(30)의 나사부(30a)를 따라 회전되다가 확경부(30b)에 위치되면, 어댑터편(51)(52)이 철근(10)으로부터 자연적으로 분리되어 확경부(30b)에 떨어지게 된다.When the adapter pieces 51 and 52 are rotated along the threaded portion 30a of the socket 30 together with the reinforcing bar 10 and positioned at the enlarged diameter portion 30b, the adapter pieces 51 and 52 are reinforcement 10 Naturally separated from the falls to the diameter portion (30b).
이러한 동작은 복수개의 모든 소켓(31)(32)(33)에서 동시에 이루어지게 되는 것으로, 어댑터(50)가 철근(10)으로부터 분리되면 철근(10)과 소켓(30)(31)(32)(33)간의 결속력이 없어지게 되어 철근(10)을 잡아 빼내게 되면 철근(10)이 자연스럽게 인출되어 철근(10)을 제거하게 된다.This operation is to be performed simultaneously in all the plurality of sockets (31) (32) (33), if the adapter 50 is separated from the reinforcing bar 10, the reinforcing bar 10 and the sockets (30) (31) (32) When the binding force between the (33) disappears and the rebar 10 is pulled out, the rebar 10 is naturally drawn out to remove the rebar 10.
따라서, 철근(10)의 제거를 위하여 어댑터(50)가 확경부(30b)에 떨어지게 되는 시점까지만 철근(10)을 회전시키고, 그 이후부터는 철근(10)을 회전시키지 않고 잡아 당기게 되면 인출되므로 종래와 같이 철근을 벽에서 완전히 인출하기 위하여 계속해서 회전시키지 않아도 된다.Therefore, the rebar 10 is rotated only until the adapter 50 falls to the enlarged diameter portion 30b to remove the reinforcing bar 10, and since the rebar 10 is pulled out without rotating the reinforcing bar 10, the conventional drawing is performed. It is not necessary to continuously rotate the rebar to pull it completely out of the wall.
그리고, 어댑터(50)에 의해 철근(10)의 고정 및 제거가 가능해져 철근(10)의 형상 변형이 불필요해지며, 즉, 종래와 같이 나사부가 구비된 고가의 철근을 사용하지 않아도 된다.In addition, the rebar 10 can be fixed and removed by the adapter 50 so that the shape deformation of the reinforcing bar 10 becomes unnecessary, that is, it is not necessary to use an expensive rebar provided with a screw part as in the prior art.
이상에서 설명한 바와 같이, 본 발명 소일 네일의 철근 설치 구조에 의하면, 철근을 일정 구간만 회전시키면 지반의 벽으로부터 제거할 수 있게 되어 제거 작업이 매우 간편해짐과 아울러, 작업 시간이 단축된다.As described above, according to the reinforcing bar installation structure of the present invention, when the reinforcing bar is rotated only a certain section, it can be removed from the wall of the ground, and the removal work becomes very simple and the working time is shortened.
그리고, 나사부가 구비된 고가의 철근을 사용하지 않아도 되므로 공사 비용을 절감할 수 있는 등의 현저한 효과가 있다.In addition, since there is no need to use expensive reinforcing bar provided with a screw, there is a remarkable effect such as reducing construction cost.
