Description

띠형 섬유보강재 및 그 제조방법{Belt Type Extile Reinforcement and Method thereof}Belt type fiber stiffener and its manufacturing method {Belt Type Extile Reinforcement and Method

본 발명은 띠형 섬유보강재 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 옹벽 형성 과정 중 흙속에 매설되어 성토층의 안정성을 향상시키거나 연약 지반에 매설되어 침하를 방지할 수 있는 섬유보강재 및 그 제조방법에 관한 것이다.The present invention relates to a band-shaped fiber reinforcement and a manufacturing method thereof, and more particularly, to reinforce in the soil during the retaining wall forming process to improve the stability of the fill layer or to be embedded in the soft ground and to prevent settlement It is about a method.

복수의 블록이 상호 적층되어 형성되는 블록형 옹벽 구조물은 제방, 산비탈 등에서 흙의 흘러내림과 붕괴를 방지하기 위하여 사용된다. 각 블록에는 적층 방향을 조절할 수 있도록 돌출부와 오목부가 적절하게 배치되어 있어서 다양한 경사도를 만들 수 있다. A block retaining wall structure formed by stacking a plurality of blocks is used to prevent soil from falling down and collapsing in embankments, hillsides, and the like. In each block, protrusions and recesses are appropriately arranged to control the stacking direction so that various inclinations can be made.

적층되는 블록에는 지반의 인장강도를 보강하기 위해 띠 형상의 섬유보강재가 설치된다. 섬유보강재는 앵커나 앵커핀 등을 사용하여 블록에 고정되며, 지반에 길게 설치되어 지면과의 접촉면에서 발생하는 마찰력을 이용해서 인발되는 힘에 저항한다. The laminated blocks are provided with a strip-shaped fiber reinforcement to reinforce the tensile strength of the ground. The fiber reinforcement is fixed to the block using anchors or anchor pins, and is installed on the ground to resist the force drawn out by using the frictional force generated in the contact surface with the ground.

띠형 섬유보강재의 일례로 한국 특허출원 제10-2004-0111929호에 개시된 조립식 보강토 옹벽 지지용 띠형 섬유보강재의 시공방법 및 이 시공방법에 사용되는 띠형 섬유보강재를 들 수 있다. 이 발명에 개시된 띠형 섬유보강재는 길이방향으로 마련되는 접힘홈을 이용하여 폭을 절반으로 접은 상태에서 블록에 형성된 보강재 삽입홈에 섬유보강재를 직접 끼워 고정함으로써, 종래의 앵커나 앵커핀 등을 사용하지 않고도 블록과 띠형 섬유보강재를 연결할 수 있도록 한다.As an example of a strip | belt-shaped fiber reinforcement, the construction method of the strip | belt-shaped fiber reinforcement for supporting prefabricated soil retaining wall disclosed in Korea Patent Application No. 10-2004-0111929, and the strip | belt-shaped fiber reinforcement used for this construction method are mentioned. The strip-shaped fiber reinforcement disclosed in the present invention by directly inserting the fiber reinforcement in the reinforcement insertion groove formed in the block in the state folded in half by using the folding groove provided in the longitudinal direction, do not use a conventional anchor or anchor pins, etc. It allows the connection between the block and the strip-shaped fiber reinforcement without connection.

However, the above-mentioned conventional strip-shaped fiber reinforcement has a disadvantage in that it easily tears to an external impact because a thin pressing the coating material covering the core material during the molding process forms a folding groove.

띠형 섬유보강재는 블록과의 연결 부위를 제외한 다른 부분 예컨대, 보강토체에 매립되는 부분은 지면과 면접촉한다. 옹벽 구조물은 토사로 이루어지는 일반성토와 자갈로 이루어지는 암성토를 성토하는 공정이 필요한데, 구조물 시공 중 암성토 자갈 등으로 인해 일반성토에 매설된 섬유보강재의 일부가 찢기거나 파이는 경우가 자주 발생한다. In the band-shaped fiber reinforcement, other parts except the connection part with the block, for example, the part embedded in the reinforcement soil, are in surface contact with the ground. Retaining wall structure requires the process of filling the general soil made of soil and rock soil made of gravel, and part of the fiber reinforcement buried in general soil is often torn or pie due to the soil soil gravel during construction of the structure.

따라서, 종래 기술에 기재한 띠형 섬유보강재를 옹벽 구조물에 시공할 경우 상기 단점으로 인해 섬유보강재가 고유의 지지 능력을 발휘하지 못하는 경우가 자주 발생하는 문제점이 있었다.Therefore, when the band-shaped fiber reinforcement described in the prior art is installed on the retaining wall structure, there is a problem that the fiber reinforcement often does not exhibit the inherent support ability due to the above disadvantages.

In addition, the strip-shaped fiber reinforcement according to the present invention was made possible by combining the coating material and the surface reinforcing material not adhered to each other with a molten resin of the same material as the coating material using a triple injection mold.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 띠형 섬유보강재를 도시한 도면이다. 도면을 참조하면 본 발명의 띠형 섬유보강재는 심재(10)와 피복재(20)와 표면보강재(30)로 이루어진다.1 is a view showing a strip-shaped fiber reinforcing material according to the present invention. Referring to the drawings, the strip-shaped fiber reinforcement of the present invention is composed of a core material 10, the coating material 20 and the surface reinforcing material (30).

심재(10)는 실질적으로 복수의 가닥으로 이루어지며, 각 가닥은 수천 가닥의 미세 섬유로 이루어져 있어서 섬유보강재에 작용하는 인장력에 저항하는 역할을 한다. 이러한 심재(10)로는 내열성을 가지며 탄성강도가 커서 강화플라스틱 등에 사용되는 폴리에스테르계 섬유가 바람직하다. The core 10 is substantially composed of a plurality of strands, each strand is composed of thousands of fine fibers to serve to resist the tensile force acting on the fiber reinforcement. The core 10 is preferably a polyester fiber which is heat-resistant and has a high elastic strength and is used for reinforced plastics.

피복재(20)는 내부 심재(10)를 보호하기 위한 것으로 LDPE와 같은 폴리에틸렌계 합성수재를 이용한다. 피복재(20)는 복수의 심재(10)를 내부에 수용하도록 마련한다. The coating material 20 is to protect the inner core 10 and uses a polyethylene-based synthetic material such as LDPE. The covering material 20 is provided to accommodate the plurality of core materials 10 therein.

표면보강재(30)는 옹벽 블록이나 도로 건설 중 투수(透水) 및 구조 보강을 위해 필수적으로 시공되는 자갈 등의 암편에 의해 발생하는 외부 충격을 피복 재(20)가 받지 않도록 피복재(20)의 상하 표면에 마련된다. Surface reinforcing material 30 is the top and bottom of the coating material 20 so that the coating material 20 does not receive the external impact generated by the rock pieces such as gravel, which is essential for the construction of the retaining wall block or road construction and reinforcement of the structure. Is provided on the surface.

표면보강재(30)로는 심재(10)와 같은 폴리에스테르 고강력사를 들 수 있다. 폴리에스테르 고강력사는 높은 강도와 인성을 모두 갖고 있는 있으며, 망상(網狀) 형태로 편직한 것을 사용한다. 아울러, 폴리에스테르는 특성상 습기에 취약하기 때문에 폴리염화비닐(PVC)로 코팅하여 편직 형태를 유지함과 동시에 습기에 강하도록 처리한다. The surface reinforcing material 30 may be a polyester high strength yarn such as the core material 10. Polyester high strength yarns have both high strength and toughness, and those knitted in a mesh form are used. In addition, since polyester is vulnerable to moisture in nature, it is coated with polyvinyl chloride (PVC) to maintain the knitting form and at the same time treated to be resistant to moisture.

본 실시예의 섬유보강재는 길이방향을 따라 접힘홈(32)을 구비한다. 접힘홈(32)은 종래기술에 기재한 바와 같이 섬유보강재를 블록에 결합시킬 때 폭을 절반으로 접은 상태로 블록에 형성된 보강재 삽입홈에 섬유보강재를 직접 끼워 고정하기 위한 것이다. 본 실시예에서는 피복재(20)를 길이방향으로 누른 후 피복재(20)의 상하 표면에 마련되는 표면보강재(30)를 상호 접촉 결합하여 형성한다. 자세한 것은 후술한다.The fiber reinforcement of this embodiment is provided with a folding groove 32 along the longitudinal direction. The fold groove 32 is for fixing the fiber reinforcement directly inserted into the reinforcement insert groove formed in the block in a state folded in half when the fiber reinforcement is bonded to the block as described in the prior art. In this embodiment, after pressing the coating material 20 in the longitudinal direction, the surface reinforcing material 30 provided on the upper and lower surfaces of the coating material 20 is formed by mutual contact coupling. Details will be described later.

도 3은 본 발명에 따른 띠형 섬유보강재를 제조하는 방법을 도시한 도면이며, 도 4는 각 공정에서의 섬유보강재 단면을 순차적으로 도시한 도면이다. Figure 3 is a view showing a method for manufacturing a strip-shaped fiber reinforcement according to the present invention, Figure 4 is a view showing a cross-section of the fiber reinforcement in each step sequentially.

도면들을 참조하면, 본 실시예에 따른 섬유보강재는 제1사출부(100)와, 제2사출부(200)와, 압착성형부(300)와, 냉각부(400)와, 인발부(500)와, 권취부(600)를 통해 제조된다.Referring to the drawings, the fiber reinforcing material according to the present embodiment is the first injection unit 100, the second injection unit 200, the compression molding unit 300, the cooling unit 400, the drawing unit 500 And a winding unit 600.

제1사출부(100)는 심재(10)에 합성수지 피복재(20)를 피복하기 위한 것으로서, 이중사출금형(110)을 이용한다. 도시한 바와 같이, 이중사출금형(110)의 일측 에서는 원사가 뭉쳐진 섬유 심재(10)가 공급되며, 타측에서는 펠릿 형태의 합성수지를 녹인 용융수지가 사출기(120)로부터 공급된다. 이중사출금형(110)의 내부 성형 온도는 약 170 ~ 180℃이며, 제1사출부(100)를 통해 배출되는 띠형 섬유보강재는 도 4의 (a) 형상을 갖는다.The first injection unit 100 is for coating the synthetic resin coating material 20 on the core material 10, using a double injection mold (110). As shown, the double core injection mold 110 is supplied with a fiber core material 10 in which yarns are agglomerated, and on the other side, a molten resin in which synthetic resin in a pellet form is supplied from the injection machine 120. The internal molding temperature of the double injection mold 110 is about 170 ~ 180 ℃, the strip-shaped fiber reinforcement discharged through the first injection portion 100 has a shape of Figure 4 (a).

제2사출부(200)는 심재(10)를 감싸고 있는 피복재(20)에 표면보강재(30)를 결합하기 위한 것으로 삼중사출금형(210)을 이용한다. 삼중사출금형(210)은 일측에서는 제1사출부(100)를 통해 배출되는 띠형 섬유보강재가 공급되며, 타측에서는 펠릿 형태의 합성수지를 녹인 용융수지가 사출기(220)로부터 공급되며, 또 다른 일측에서는 표면보강재(30)가 와인더(230)로부터 공급된다. 삼중사출금형(210)의 내부 성형 온도는 이중사출금형(210)과 마찬가지로 약 170 ~ 180℃이다.The second injection unit 200 uses the triple injection mold 210 to couple the surface reinforcing material 30 to the covering material 20 surrounding the core material 10. The triple injection mold 210 is supplied with a strip-shaped fiber reinforcement discharged through the first injection unit 100 at one side, and melted resin melted from a pellet-type synthetic resin is supplied from the injection machine 220 at the other side. The surface reinforcement material 30 is supplied from the winder 230. The internal molding temperature of the triple injection mold 210 is about 170 ~ 180 ℃ like the double injection mold (210).

여기서, 사출기(220)로부터 공급되는 용융수지는 피복재(20)와 동일한 합성수지재가 바람직하다. 이것은, 이중사출금형(110)에서 배출된 후 어느 정도 고형화된 도 4의 (a) 형태의 띠형 섬유보강재와 표면보강재(30)는 서로 붙지 않기 때문에, 용융수지를 삼중사출금형(210)에서 다시 공급함으로써 피복재(20)와 표면보강재(30)를 붙이기 위함이다. Here, the molten resin supplied from the injection machine 220 is preferably the same synthetic resin material as the coating material 20. This is because the strip-shaped fiber reinforcement and the surface reinforcing material (30) of Figure 4 (a) is solidified to some extent after being discharged from the double injection mold 110, the molten resin in the triple injection mold 210 again. This is for attaching the coating material 20 and the surface reinforcing material 30 by supplying.

제2사출부(200)를 통해 배출되는 띠형 섬유보강재는 도 4의 (b) 형상을 갖는다. 도 4에서는 표면보강재(30)와 용융수지층(34)이 서로 다른 층을 이루는 것으로 도시하였으나, 이는 설명을 돕기 위해 과장해서 도시한 것이며 실제로는 용융수지가 망상 형태의 표면보강재(30) 사이사이에 침투하여 동일한 층을 형성한다. 제2사출부(200)를 통해 배출되는 섬유보강재는 후공정인 압착성형부(300)에서의 성형성 을 높이기 위해 에어블로워(240)를 통해 약 120℃로 냉각시킨다. The strip-shaped fiber reinforcement discharged through the second injection unit 200 has a shape of FIG. 4 (b). In FIG. 4, the surface reinforcing material 30 and the molten resin layer 34 are shown to form different layers. However, the surface reinforcing material 30 and the molten resin layer 34 are exaggerated for clarity. Penetrate into and form the same layer. The fiber reinforcement discharged through the second injection unit 200 is cooled to about 120 ° C. through the air blower 240 in order to increase the formability in the compression molding unit 300 which is a post-process.

압착성형부(300)는 제2사출부(200)에서 배출된 섬유보강재에 흙과의 마찰력 증대를 위한 표면 해칭과 접힘홈(32)을 성형하기 위한 것으로서, 압착롤러(310)를 사용한다. 압착롤러(310, 제1압착롤러)의 외주에는 본 발명의 띠형 섬유보강재의 접힘홈(32)을 형성할 수 있도록 원주돌기가 가공되어 있다. 원주돌기는 피복재(20)를 길이방향으로 눌러 피복재(20)의 상하 표면에 결합되어 있는 표면보강재(30)가 상호 근접하도록 한다. 압축성형부(300)를 통해 배출되는 띠형 섬유보강재는 도 4의 (c) 형상을 갖는다. The compression molding part 300 is to form the surface hatching and the folding groove 32 for increasing the frictional force with the soil on the fiber reinforcement discharged from the second injection part 200, and uses the compression roller 310. A circumferential protrusion is formed on the outer circumference of the pressing roller 310 and the first pressing roller so as to form the folding groove 32 of the strip-shaped fiber reinforcing material of the present invention. The circumferential protrusion presses the covering member 20 in the longitudinal direction so that the surface reinforcing members 30 coupled to the upper and lower surfaces of the covering member 20 are close to each other. The strip-shaped fiber reinforcement discharged through the compression molding part 300 has a shape of FIG.
