Description

나선형코일이 구비된 콘크리트 타설용 수송관{Concrete Conveying Pipe with Spiral Coil}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] Concrete Conveying Pipe with Spiral Coil Having Spiral Coil [

본 발명은 나선형코일이 구비된 콘크리트 타설용 수송관에 관한 것으로서, 수송관로를 둘러싸는 나선형코일에 전원을 인가하여 전자기장을 유도함으로써 수송관로 내부롤 통하여 타설되는 콘크리트에 포함된 감섬유에 규칙적인 방향성을 제공할 수 있는 것을 특징으로 한다.The present invention relates to a concrete pipe for pouring concrete having a helical coil, and more particularly, to a spiral coil which surrounds a conveying pipe and induces an electromagnetic field by applying power to the spiral coil, Can be provided.

현재 강섬유를 이용하여 콘크리트의 보강하기 위한 기술은 다양한 연구자들에 의해서 제시되고 있는데, 콘크리트에 혼입되는 강섬유는 2~8cm 정도의 작은 크기를 가지며, 매우 많은 양이 다른 골재들과 함께 콘크리트에 배합된다.Currently, the technique for reinforcing concrete by using steel fiber is suggested by various researchers. The steel fiber mixed in concrete has a small size of 2 ~ 8 cm and very much amount is mixed with concrete with other aggregates .

강섬유가 혼입된 콘크리트가 타설될 경우 다른 골재들과 마찬가지로 강섬유의 배치 방향이 무작위로 분포될 수밖에 없는데, 강섬유는 콘크리트 구조물에 발생되는 주요 하중과 일치하는 방향으로 더 많이 배치될수록 효율적인 제어가 가능하여 보강성능을 보다 쉽게 확보할 수 있다. If the concrete containing the steel fiber is laid, the arrangement direction of the steel fiber is inevitably distributed like the other aggregates. The more the steel fiber is disposed in the direction matching the main load generated in the concrete structure, Performance can be more easily secured.

그러나 현재까지는 강섬유의 방향성을 제어할 수 없기 때문에 강섬유 재료 사용에 있어서 효율성이 매우 떨어지는 문제점이 있다.However, since the directionality of the steel fiber can not be controlled up to now, there is a problem that the efficiency of using the steel fiber material is very low.

상기한 문제점을 해결하기 위하여 창작된 본 발명은 콘크리트에 혼입되어 타설되는강섬유에 규칙적인 방향성을 부여하여 보강성능을 극대화시키는 것을 목적으로 한다.In order to solve the above problems, it is an object of the present invention to maximize reinforcing performance by imparting regular directionality to a steel fiber embedded in concrete.

상기한 목적을 달성하기 위하여 창작된 본 발명의 구성은 다음과 같다.In order to achieve the above object, the present invention is as follows.

본 발명은 타설되는 콘크리트에 혼입된 강섬유에 방향성을 제공하는 콘크리트 타설용 수송관에 관한 것으로서, 타설되는 콘크리트를 수송하는 관로 역할을 하는 수송관로(110); 및, 상기 수송관로(110)를 둘러싸도록 감겨지는 나선형코일(120);로 구성되며, 상기 나선형코일(120)의 양측 단부에 전원이 인가될 경우 발생되는 전자기장에 의하여 타설되는 콘크리트(11)에 혼입된 강섬유(22)가 일정한 방향성을 가지도록 분포되면서 콘크리트가 타설되는 것을 특징으로 한다.The present invention relates to a concrete pipe for concrete pouring, which provides directionality to a steel fiber mixed in a concrete to be laid, comprising: a conveyance pipe (110) serving as a pipe for conveying concrete to be poured; And a spiral coil 120 wound around the pipeline 110. The spiral coil 120 is wound on the concrete 11 pushed by an electromagnetic field generated when power is applied to both ends of the spiral coil 120 And the concrete is inserted while the mixed steel fibers 22 are distributed so as to have a certain directionality.

본 발명의 구성에 따른 기술적 효과는 다음과 같다.Technical effects of the configuration of the present invention are as follows.

첫째, 콘크리트의 타설을 위한 수송과정에서 자동적으로 콘크리트(11)에 포함된 강섬유(22)가 일정한 방향성이 부여될 수 있으며, 별도의 추가 공정이 불필요하다.First, the steel fiber 22 included in the concrete 11 can be automatically imparted with a certain directionality during transportation for pouring concrete, and a separate additional process is unnecessary.

둘째, 기존 수송관로(110)의 외부에 나선형코일(120)만 감겨지도록 설치하고 전원만 연결하면 전자기장이 발생하여 강섬유(22)에 일정한 방향성이 부여되는 구조로서, 기존 장비에도 추가 비용을 최소화하여 설치할 수 있다.Secondly, if only the spiral coil 120 is wound on the outer side of the existing transmission line 110 and only the power source is connected, an electromagnetic field is generated and a certain direction is given to the steel fiber 22, Can be installed.

셋째, 작업 여건 및 재료의 특성에 따라 나선형코일(120)이 감겨지는 피치값을 자유롭게 조절할 수 있다.Third, the pitch value at which the helical coil 120 is wound can be freely adjusted according to the working conditions and the characteristics of the material.

도1은 본 발명의 구체적 실시예를 도시한다.
도2는 본 발명인 콘크리트 타설용 수송관을 통과하면서 방향성이 부여된 강섬유(22)를 도시한다.
도3은 다양한 피치값이 적용된 본 발명의 구체적 실시예를 도시하는데, (a)피치값이 서서히 감소하는 경우, (b)피치값이 서서히 증가하는 경우, 및 (c)피치값이 구획별로 달리 적용된 경우를 각각 도시한다.Figure 1 shows a specific embodiment of the present invention.
Fig. 2 shows a steel fiber 22 having a directionality while passing through a concrete pipe for concrete pouring according to the present invention.
Fig. 3 shows a specific embodiment of the present invention in which various pitch values are applied, wherein (a) the pitch value gradually decreases, (b) the pitch value gradually increases, and (c) Respectively.

이하에서는 본 발명의 구체적 실시예를 첨부도면을 참조하여 보다 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

타설되는 콘크리트에 혼입된 강섬유에 방향성을 제공하는 콘크리트 타설용 수송관에 관한 것으로서, 도1에 도시된 것처럼 수송관로(110)와 수송관로(110)를 둘러싸도록 감겨지는 나선형코일(120)로 구성된다.The present invention relates to a concrete pipe for concrete pouring which provides directionality to a steel fiber mixed in concrete to be poured, and is composed of a conveying pipe 110 and a spiral coil 120 wound around the conveying pipe 110 as shown in Fig. do.

수송관로(110)는 타설되는 콘크리트를 수송하는 관로 역할을 하는데, 다양한 골재와 강섬유(22)가 혼입된 콘크리트(11)는 이러한 수송관로(110)를 통과하여 타설된다.The conveying line 110 serves as a conduit for conveying the concrete to be laid. The concrete 11 mixed with various aggregates and the steel fiber 22 is poured through the conveying line 110.

나선형코일(120)은 이러한 수송관로(110)를 둘러싸도록 감겨지는데, 나선형코일(120)의 양측 단부에 전원이 인가될 경우 발생되는 전자기장에 의하여 타설되는 콘크리트(11)에 혼입된 강섬유(22)가 일정한 방향성을 가지도록 분포되면서 콘크리트가 타설될 수 있다.The spiral coil 120 is wrapped around such a pipeline 110. The spiral coil 120 is wound with a steel fiber 22 mixed in a concrete 11 pushed by an electromagnetic field generated when power is applied to both ends of the spiral coil 120, The concrete can be poured while having a certain directionality.

다시 말하면, 도2에 도시된 것처럼 나선형코일(120)이 구비된 수송관로(110)를 통과하기 전의 상태(콘크리트 상태1)에서는 강섬유(22)가 콘크리트(11) 내부에 방향성 없이 무작위로 분포함에 반하여 나선형코일(120)이 구비된 수송관로(110)를 통관한 상태(콘크리트 상태2)에서는 강섬유가 전자기장에 의하여 일방향으로 규칙적으로 배열된 상태가 됨을 확인할 수 있다.In other words, in the state (concrete state 1) before passing through the pipeline 110 having the helical coil 120 as shown in FIG. 2, the steel fiber 22 is randomly distributed in the concrete 11 (Concrete state 2) in which the conduit 110 having the spiral coil 120 is opened, the steel fibers are regularly arranged in one direction by the electromagnetic field.

이러한 나선형코일(120)은 수송관로(110)의 단위길이당 감겨지는 권선수(피치값)를 조절하거나 감겨지는 영역의 면적을 조절할 수 있다.The helical coil 120 can adjust the winding area (pitch value) wound around the transport channel 110 per unit length or adjust the area of the wound area.

즉, 도3(a)에 도시된 것처럼 피치값이 점점 감소하도록 감겨질 수도 있고, 도3(b)처럼 피치값이 점점 증가하도록 감겨질 수도 있다.That is, the pitch value may be wound so as to decrease gradually as shown in FIG. 3 (a), or may be wound so that the pitch value gradually increases as shown in FIG. 3 (b).

아울러, 나선형코일(120)은 도3(c)에 도시된 것처럼 감겨지는 영역을 구분하여 수송관로(110)의 단위길이당 감겨지는 권선수를 달리 적용할 수도 있다In addition, the helical coil 120 may be divided into a plurality of wound areas as shown in FIG. 3 (c)

나선형코일(120)은 외부 전원이 연결되는 양측 단부를 제외한 나머지 영역은 절연처리되어 안정성을 확보할 필요가 있는데, 수송관로(110)의 외주면에 감겨질 경우 별도의 피복이나 피막 처리를 하는 것이 바람직하다.The spiral coil 120 needs to be insulated to ensure stability, except for both ends where the external power source is connected. It is preferable that the spiral coil 120 be coated with another coating or film when it is wound around the outer circumferential surface of the transport channel 110 Do.

상기한 바와 같이 본 발명의 구체적 실시예를 첨부도면을 참조하여 설명하였으나 본 발명의 보호범위가 반드시 이러한 실시예에만 한정되는 것은 아니며 본 발명의 기술적 요지를 변경하지 않는 범위 내에서 다양한 설계변경, 공지기술의 부가나 삭제, 단순한 수치한정 등의 경우에도 본 발명의 보호범위에 속함을 분명히 한다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Addition or deletion of a technique, and limitation of a numerical value are included in the protection scope of the present invention.
