Description
본 발명은 이웃하는 PHC 파일의 이음면에 동일한 형상과 규격의 지압연결판을 날개판과 공간부가 상호 엇갈리도록 배치한 후 사이에 형성된 고정홀에 전단고정핀을 삽입하는 간단한 공정으로 PHC 파일 연결구를 시공할 수 있어, PHC 파일 연결구의 두께를 얇게 구성하여 경제적이고 제작이 편리하며 시공성과 안전성이 우수한 PHC 파일 연결구에 대한 것이다.The present invention constructs a PHC file connector by a simple process of inserting a shear fixing pin into a fixing hole formed between a wing plate and a space part of the acupressure connecting plate of the same shape and standard on the joint surface of a neighboring PHC pile. It is possible to construct a thin PHC pile connector, economical and convenient to manufacture, construction and safety excellent PHC pile connector.
최근 기성 콘크리트 파일 공법에서는 프리텐션 방식에 의한 원심력을 이용하여 제조된 고강도 콘크리트 말뚝인 PHC 파일(pretensioned spun high strength concrete pile)이 많이 사용되고 있다. In the recent concrete pile method, PHC pile (pretensioned spun high strength concrete pile), which is a high-strength concrete pile manufactured by centrifugal force by a pretension method, is widely used.
이러한 PHC 파일은 제작 및 운반을 위해 길이에 제한이 있으므로, 현장에서 복수의 파일을 연결하여 사용한다.Since these PHC files are limited in length for manufacturing and transportation, multiple files may be connected and used in the field.
종래 PHC 파일은 현장에서 이음하기 위해 용접 이음을 많이 사용하였다. 그러나 현장 용접은 작업자의 숙련도 및 현장 기상 상태의 영향을 많이 받는다. 그러므로 균질한 용접 품질을 기대하기 어렵고, 용접 시간이 많이 소요되며, 고압 전기 및 용접 불꽃 등으로 인한 안전사고의 우려가 크다. 뿐만 아니라 용접을 위해 용접 가능한 용접용 강판을 별도로 파일 단부에 설치하여야 하므로 비용이 상승하는 문제점이 있다.Conventional PHC piles use many welded joints to join in the field. However, field welding is heavily influenced by operator skill and on-site weather conditions. Therefore, it is difficult to expect a homogeneous welding quality, it takes a lot of welding time, there is a great risk of safety accidents due to high voltage electricity and welding sparks. In addition, there is a problem that the cost increases because the weldable steel sheet for welding must be separately installed at the pile end.
이에 최근에는 도 1과 같이 별도의 연결구(6)를 상하부 파일(1a, 1b)에 볼트로 체결하는 기계식 이음 비중이 증가하고 있다(등록실용신안 제20-0345924호 등).In recent years, as shown in FIG. 1, the proportion of mechanical joints for fastening the separate connector 6 to the upper and lower piles 1a and 1b with bolts has increased (Registration Utility Model No. 20-0345924, etc.).
그러나 이러한 볼트 체결 방식은 공구를 삽입하여 볼트를 체결하기 위해 소정의 공간이 필요하므로 연결구(6)의 크기가 커지게 되고, 이로 인해 강재 소요량이 상당하여 비경제적이다. 또한, 연결구(6)의 수직보강판(61) 사이 협소한 공간 내에서 볼트를 체결하여야 하므로, 볼트 조임을 수작업에만 의존할 수밖에 없어 균일한 체결력 확보가 어렵다. 아울러 연결구(6) 내에 볼트 헤드가 노출되므로 항타 등 진동에 의해 볼트가 풀릴 수 있는 단점이 있다.However, the bolt fastening method requires a predetermined space for fastening the bolt by inserting a tool, thereby increasing the size of the connector 6, which is uneconomical due to the considerable amount of steel requirements. In addition, since the bolt must be fastened in a narrow space between the vertical reinforcing plate 61 of the connector 6, it is difficult to secure a uniform fastening force because it can only rely on tightening the bolt manually. In addition, since the bolt head is exposed in the connector 6, there is a disadvantage that the bolt can be released by vibration, such as driving.
뿐만 아니라 최근에는 고강도 콘크리트를 사용하여 PHC 파일 본체의 강도가 크게 증가하였다. 그런데 기존 연결구(6)의 수직보강판(61)은 두께 증가에 한계가 있어, PHC 파일 본체가 지지할 수 있는 최대 지지력에 도달하기 전에 연결구(6)의 수직보강판(61)이 좌굴을 일으킬 수 있어 비경제적인 설계가 이루어질 수밖에 없다.In addition, recently, the strength of the PHC pile body has been greatly increased by using high-strength concrete. However, the vertical reinforcement plate 61 of the existing connector 6 has a limit to increase in thickness, so that the vertical reinforcement plate 61 of the connector 6 causes buckling before reaching the maximum supporting force that the PHC pile body can support. Inevitably, economical design is inevitable.
아울러 이러한 종래 연결구(6)는 압축 응력이 주로 수직보강판(61)에 의해 전달된다. 그러므로 수직보강판(61) 주변에서 응력 집중이 발생하여 파일 연결 단부에서 지압 응력이 불균등하게 분포하므로 구조적으로 바람직하지 않고, 상하부연결판(62, 63)에 휨 변형이 발생할 수 있다. 나아가 지압 응력을 균등하게 분포시키기 위해서는 상하부연결판(62, 63)을 두껍게 형성하여야 하는데, 이 경우 연결구(6)의 강재량이 증가하여 비경제적이다.In addition, the conventional connector 6 is a compressive stress is mainly transmitted by the vertical reinforcing plate (61). Therefore, since stress concentration occurs around the vertical reinforcing plate 61 and the pressure stress is unevenly distributed at the end of the pile connection, it is not structurally preferable, and bending deformation may occur in the upper and lower connecting plates 62 and 63. Furthermore, in order to distribute the acupressure stress evenly, the upper and lower connecting plates 62 and 63 should be formed thickly, in which case the amount of steel in the connector 6 increases, which is uneconomical.

다른 바람직한 실시예에 따른 본 발명은 상기 지압연결판의 날개판은 날개판의 내측 또는 외측에 형성된 연결링에 의해 상호 연결되는 것을 특징으로 하는 PHC 파일 연결구를 제공한다. The present invention according to another preferred embodiment provides a PHC pile connector characterized in that the wing plate of the acupressure connecting plate is interconnected by a connection ring formed on the inside or outside of the wing plate.
다른 바람직한 실시예에 따른 본 발명은 상기 연결링은 두께가 날개판의 1/2로 형성되어, 결합되는 지압연결판의 연결링과 겹쳐지도록 구성되는 것을 특징으로 하는 PHC 파일 연결구를 제공한다.According to another preferred embodiment of the present invention, the connecting ring is formed to have a thickness of 1/2 of the wing plate, and provides a PHC pile connector characterized in that it is configured to overlap the connecting ring of the acupressure connecting plate to be coupled.
상기와 같은 본 발명에 따르면 다음과 같은 효과가 있다. According to the present invention as described above has the following effects.
첫째, PHC 파일 연결구를 구성하는 상하부 지압연결판을 이격시키기 위한 별도의 수직 보강재가 필요 없다. 따라서 PHC 파일 연결구의 두께를 매우 얇게 구성할 수 있으므로, 소요 강재량을 최소화할 수 있다. First, there is no need for a separate vertical reinforcement to separate the upper and lower acupressure connecting plate constituting the PHC pile connector. Therefore, the thickness of the PHC pile connector can be made very thin, thereby minimizing the amount of steel required.
둘째, 일측 PHC 파일 및 타측 PHC 파일의 이음면에 각각 미리 볼트 체결된 상하부 지압연결판을 날개판과 공간부가 상호 엇갈리게 배치한 후 사이에 형성된 고정홀에 전단고정핀을 삽입하는 간단한 공정으로 PHC 파일 연결구를 시공할 수 있다. 따라서 용접 공정 없이 간단하게 이웃하는 PHC 파일을 연결할 수 있어 안전성이 우수하다. 아울러 PHC 파일 연결 전에 미리 지압연결판을 볼트 체결하므로, 볼트와의 간섭 없이 PHC 파일 연결 작업을 쉽게 진행할 수 있어 시공성이 우수하다. Second, PHC pile connector is a simple process of inserting shear fixing pins into the fixing holes formed between the wing plate and the space part after arranging the upper and lower shiatsu connecting plates bolted to the joint surfaces of one side PHC pile and the other side PHC pile. Can be constructed. Therefore, it is easy to connect neighboring PHC files without welding process, so the safety is excellent. In addition, since the acupressure connecting plate is bolted in advance before the PHC file connection, PHC file connection work can be easily performed without interference with the bolt, so the construction is excellent.
셋째, PHC 파일 연결구에서 좌굴되는 부재가 없고, 콘크리트와 동일한 형상 및 면적을 갖는 상하부 지압연결판에 의해 응력 전달이 직접 이루어지므로 지압 응력 분포가 매우 균등하여 응력 집중이 없으며, 내력이 매우 커 PHC 파일 본체에 고강도 콘크리트를 사용하더라도 응력 전달에 전혀 문제가 없다.Third, since there is no member buckling at the PHC pile connector and direct stress transfer is made by the upper and lower bearing plate having the same shape and area as the concrete, the stress distribution is very uniform and there is no stress concentration. The use of high-strength concrete in the body does not cause any problem in stress transmission.
넷째, 전단고정핀이 볼트 횡단면(원형)의 전단이 아니라 종단면(직사각형)의 전단에 의해 지지되므로, 상하부 지압연결판의 날개판이 결합되는 경계부에서 지지내력이 매우 높다. Fourth, because the shear fixing pin is supported by the front end of the longitudinal section (rectangular) rather than the front end of the bolt cross-section (circular), the bearing strength is very high at the boundary where the wing plate of the upper and lower shiatsu connection plate is coupled.
다섯째, 일측 PHC 파일 및 타측 PHC 파일에 접합되는 PHC 파일 연결구를 동일한 형상으로 제작할 수 있으므로 제작 및 관리 효율이 우수하고, 현장 조립시 작업 관리가 용이하다.Fifth, since the PHC file connector connected to the one side PHC file and the other side PHC file can be manufactured in the same shape, the production and management efficiency is excellent, and the work management during the field assembly is easy.
여섯째, 상하부 지압연결판의 날개판을 볼트 체결하기 위하여 형성된 관통공의 입구측 단부에 확장공이 형성되는 경우, 볼트 헤드가 확장공에 삽입되어 외부로 노출되지 않는다. 이에 따라 항타 등 외력에 의하여 볼트의 체결력이 저하되지 않고 견고하게 결합 가능하다. Sixth, when the expansion hole is formed at the inlet end of the through hole formed to bolt the wing plate of the upper and lower pressure connecting plate, the bolt head is inserted into the expansion hole is not exposed to the outside. Accordingly, the fastening force of the bolt can be firmly coupled without external force due to external force such as driving.
일곱째, 두 파일의 조립을 용이하게 하기 위해 일측 파일의 날개판과 타측 파일의 날개판 사이에 소정의 간격이 존재하더라도 연결링이 두 파일의 중심이 일치하도록 하는 가이드 역할을 할 수 있다.Seventh, even if there is a predetermined distance between the wing plate of the one pile and the wing plate of the other pile to facilitate the assembly of the two piles, the connecting ring may serve as a guide to the center of the two piles.

본 발명은 상하로 이웃하는 PHC 파일(1a, 1b) 연결시, PHC 파일 연결구의 크기를 최소화하여 경제성이 뛰어나면서도 파일 이음 시공성과 안정성이 우수한 PHC 파일 연결구를 제공하기 위한 것이다.The present invention is to provide a PHC file connector that is excellent in economy and excellent pile joint construction and stability by minimizing the size of the PHC file connector when connecting the neighboring PHC file (1a, 1b) up and down.
이하, 편의상 하부의 PHC 파일을 일측 PHC 파일(1a), 상부의 PHC 파일을 타측 PHC 파일(1b)로 설명한다.Hereinafter, for convenience, the lower PHC file will be described as one PHC file 1a and the upper PHC file as another PHC file 1b.
상기 일측 PHC 파일(1a)과 타측 PHC 파일(1b)의 상호 대면하는 단부에는 각각 지압연결판(2, 3)이 고정되며, 한 쌍의 지압연결판(2, 3)의 결합에 의하여 일측 PHC 파일(1a)과 타측 PHC 파일(1b)이 결합된다. Acupressure connecting plates 2 and 3 are respectively fixed to end portions of the one side PHC pile 1a and the other side PHC pile 1b that are coupled to each other, and the one side PHC is connected by a pair of acupressure connecting plates 2 and 3. The pile 1a and the other PHC pile 1b are combined.
상기 지압연결판(2, 3)은 복수의 날개판(21, 31) 및 상기 날개판(21, 31)과 동일한 형상을 갖는 공간부(22, 32)가 상기 PHC 파일(1a, 1b)의 단부 면을 따라 원형의 띠 형상으로 교대로 배치되어 일측 지압연결판(2, 3)의 공간부(22, 32)에 타측 지압연결판(2, 3)의 날개판(21, 31)이 끼움 결합되도록 구성된다. The acupressure connecting plates 2 and 3 have a plurality of wing plates 21 and 31 and spaces 22 and 32 having the same shape as the wing plates 21 and 31 are formed of the PHC piles 1a and 1b. Wing plates 21 and 31 of the other acupressure connecting plates 2 and 3 are fitted into the spaces 22 and 32 of the one acupressure connecting plates 2 and 3 so as to be alternately arranged in a circular band shape along the end face. Configured to be combined.
즉, 상기 지압연결판(2, 3)의 날개판(21, 31)과 공간부(22, 32)는 서로 대응되는 형상으로 형성되어, 일측 지압연결판(2)의 날개판(21)은 타측 지압연결판(3)의 공간부(32)에 삽입되고, 일측 지압연결판(2)의 공간부(22)에는 타측 지압연결판(3)의 날개판(31)이 삽입되도록 구성된다.That is, the wing plates 21 and 31 and the space portions 22 and 32 of the acupressure connecting plates 2 and 3 are formed in a shape corresponding to each other, so that the wing plate 21 of the acupressure connecting plate 2 is It is inserted into the space portion 32 of the other acupressure connection plate 3, and the wing plate 31 of the other acupressure connection plate 3 is inserted into the space portion 22 of the one acupressure connection plate (2).
이에 따라 일측 PHC 파일(1a)과 타측 PHC 파일(1b)에 각각 결합되는 지압연결판(2, 3)은 서로 동일한 형상으로 제작 가능하다.Accordingly, the acupressure connecting plates 2 and 3 respectively coupled to the one side PHC file 1a and the other side PHC file 1b may be manufactured in the same shape.
상기 한 쌍의 지압연결판(2, 3)이 상호 결합된 상태에서 PHC 파일 연결구의 형상 및 면적은 PHC 파일(1a, 1b) 선단의 형상 및 면적과 동일하게 구성한다.In the state where the pair of acupressure connecting plates 2 and 3 are coupled to each other, the shape and area of the PHC pile connector are the same as the shape and area of the tips of the PHC piles 1a and 1b.
상기 공간부(22, 32) 내에 날개판(21, 31)이 삽입 가능하도록 공간부(22, 32)의 폭은 날개판(21, 31) 폭보다 약간 크게 형성하는 것이 바람직하다.The widths of the spaces 22 and 32 may be slightly larger than the widths of the wing plates 21 and 31 so that the wing plates 21 and 31 can be inserted into the spaces 22 and 32.
상기 상하부 지압연결판(2, 3)의 날개판(21, 31)은 이웃하는 경계부에서 빈틈이 발생하지 않고 서로 밀착되도록 구성할 수 있다. The wing plates 21 and 31 of the upper and lower acupressure connecting plates 2 and 3 may be configured to be in close contact with each other without generating gaps at neighboring boundaries.
상하부 지압연결판(2, 3)은 강판인 플레이트를 절단하거나 또는 주물 등에 의해 제작 가능하다. The upper and lower parts of the connecting plate (2, 3) can be produced by cutting the plate which is a steel plate or by casting.
상기 날개판(21, 31)의 양 측단에는 결합홈부(211, 311)가 측단 길이 방향으로 형성되어, 인접하는 양측 날개판(21, 31)의 결합홈부(211, 311)에 의해 형성된 고정홀(H)에 전단고정핀(4)이 끼워져 한 쌍의 지압연결판(2, 3)이 상호 결합된다. Coupling grooves 211 and 311 are formed at both side ends of the wing plates 21 and 31 in the longitudinal direction, and fixing holes formed by the coupling grooves 211 and 311 of the adjacent wing plates 21 and 31 are adjacent to each other. Shear fixing pin 4 is fitted to (H) is a pair of acupressure connecting plate (2, 3) are mutually coupled.
즉, 상기 날개판(21, 31)의 양 측단에는 결합홈부(211, 311)가 형성되어 일측 지압연결판(2, 3)의 날개판(21, 31)과 이에 인접하는 타측 지압연결판(2, 3)의 날개판(21, 31) 사이의 결합홈부(211, 311)에 의해 형성된 고정홀(H)에 전단고정핀(4)을 끼워 한 쌍의 지압연결판(2, 3)을 서로 고정한다(도 7).That is, coupling grooves 211 and 311 are formed at both side ends of the wing plates 21 and 31 so that the wing plates 21 and 31 of one of the acupressure connecting plates 2 and 3 and the other acupressure connecting plate adjacent thereto. A pair of acupressure connecting plates (2, 3) are inserted by inserting the shear fixing pin (4) into the fixing hole (H) formed by the coupling grooves (211, 311) between the wing plates (21, 31) of the 2,3. Fix to each other (FIG. 7).
종래 수직 보강판의 면내 축력에 의해 하중을 전달하는 기존의 연결구와는 달리 본 발명은 면 부재인 지압연결판(2, 3)의 직접 지압 응력(bearing stress)에 의해 하중을 전달한다.Unlike conventional connectors that transfer loads by in-plane axial forces of conventional vertical reinforcement plates, the present invention transfers loads by direct bearing stress of the acupressure connecting plates 2 and 3, which are face members.
이에 따라 좌굴에 대한 우려가 없고, 접합부 내력이 커서 PHC 파일(1a, 1b)의 본체에 초고강도 콘크리트를 적용하더라도 PHC 파일(1a, 1b)의 내력을 충분히 활용할 수 있다.Accordingly, there is no concern about buckling, and the joint strength is large, and even if ultra-high strength concrete is applied to the main bodies of the PHC piles 1a and 1b, the strength of the PHC piles 1a and 1b can be sufficiently utilized.
도 8에 도시된 바와 같이, 상하부 지압연결판(2, 3)의 하나의 날개판(21, 31)을 고려하면, 상하의 PHC 파일(1a, 1b)에 인장력이 작용하여 PHC 파일 연결구에서 인장 응력이 발생하는 경우, 전단고정핀(4)이 일측(하부의 PHC 파일(1a)에 연결된 날개판(21) 측)은 상부에서 타측(상부의 PHC 파일(1b)에 연결된 날개판(31) 측)은 하부에서 지압이 발생한다. 이에 전단고정핀(4) 좌우의 날개판(21, 31)은 서로 외측으로 벌어지는 힘이 발생한다. 그러나 날개판(21, 31)들은 복수 개가 서로 밀착된 원형의 폐합(閉合)된 루프(loop)를 이루므로, 서로를 구속하여 전단고정핀(4) 좌우의 날개판(21, 31) 사이가 벌어지지 않고 견고하게 지지된다.As shown in FIG. 8, when one wing plate 21, 31 of the upper and lower pressure connecting plates 2 and 3 is considered, a tensile force acts on the upper and lower PHC piles 1a and 1b, thereby causing a tensile stress in the PHC pile connector. In this case, the shear fixing pin 4 has one side (the wing plate 21 side connected to the lower PHC pile 1a) on the other side (the wing plate 31 side connected to the upper PHC pile 1b). ) Acupressure at the bottom. Accordingly, the wing plates 21 and 31 on the left and right sides of the shear fixing pins 4 generate a force that spreads outward from each other. However, since the wing plates 21 and 31 form a circular closed loop in which a plurality of the wing plates 21 and 31 are in close contact with each other, the wing plates 21 and 31 are restrained from each other so that the wing plates 21 and 31 on the left and right sides of the shear fixing pins 4 are separated. It is firmly supported without opening.

At this time, it is preferable that the shear fixing pin 4 uses the same diameter as the fixing hole (H) so that it can be inserted into the fixing hole (H) by hitting with no extra play.
도 9에 도시된 바와 같이, 상기 전단고정핀(4)의 전단에는 고정홀(H) 입구에 삽입이 용이하도록 면취(chamfer)를 형성하는 것이 바람직하다.As shown in Figure 9, the front end of the shear fixing pin (4) it is preferable to form a chamfer (chamfer) to facilitate insertion into the fixing hole (H) inlet.
상기 전단고정핀(4)은 볼트를 사용할 수 있으며, 타격에 의해 신속하게 설치할 수 있도록 볼트 몸통 외주면에 나사산이 없는 핀을 사용하는 것이 바람직하다.The shear fixing pin 4 may use a bolt, it is preferable to use a pin without a thread on the outer peripheral surface of the bolt body so that it can be quickly installed by the hit.
상기 상하부 지압연결판(2, 3)은 서로 연결되기 전에 미리 PHC 파일(1a, 1b)의 제작 공장 또는 현장에서 일측 PHC 파일(1a)의 이음면과 타측 PHC 파일(1b)의 이음면에 각각 고정 가능하다.The upper and lower acupressure connecting plates 2 and 3 may be fixed to the joint surface of one side PHC pile 1a and the joint surface of the other side PHC pile 1b before being connected to each other in a manufacturing factory or a site of PHC piles 1a and 1b. Do.
도 10에 도시된 바와 같이, 상하부 지압연결판(2, 3)은ㅤ강선(12) 정착을 위해 PHC 파일(1a, 1b)의 단부에 매립된 PC 너트(11)에 볼트(B)를 체결하여 각각 일측 PHC 파일(1a) 및 타측 PHC 파일(1b)의 이음면에 고정 가능하다. 이 경우 상하부 지압연결판(2, 3)의 날개판(21, 31)은 각각 일측 PHC 파일(1a)과 타측 PHC 파일(1b)의 이음면에 형성된 볼트 체결공, 즉 PC 너트(11)의 개수만큼 구비될 수 있다.As shown in FIG. 10, the upper and lower acupressure connecting plates 2 and 3 fasten the bolt B to the PC nut 11 embedded at the ends of the PHC piles 1a and 1b for fixing the steel wire 12. It can be fixed to the joint surface of one side PHC file (1a) and the other side PHC file (1b), respectively. In this case, the wing plates 21 and 31 of the upper and lower acupressure connecting plates 2 and 3 respectively have bolt fastening holes formed on the joint surfaces of one side PHC pile 1a and the other side PHC pile 1b, that is, the number of PC nuts 11. It can be provided as much.
또는, 상하부 지압연결판(2, 3)은 별도의 상하부 캡(미도시) 없이 콘크리트 본체의 단부에 직접 맞닿도록 고정할 수 있다.Alternatively, the upper and lower acupressure connecting plates 2 and 3 may be fixed to directly contact the ends of the concrete body without a separate upper and lower caps (not shown).
도 10에 도시된 바와 같이, 상기 날개판(21, 31)의 상하부 모서리에는 이들 부재의 원활한 결합을 위해 면취(chamfer)를 형성할 수 있다. As illustrated in FIG. 10, chamfers may be formed at upper and lower edges of the wing plates 21 and 31 to smoothly couple these members.
본 발명에 따르면 PHC 파일 연결구를 구성하는 상하부 지압연결판(2, 3)을 이격시키기 위한 별도의 수직 보강재가 필요 없다. 따라서 PHC 파일 연결구의 두께를 매우 얇게 구성할 수 있으므로, 소요 강재량을 최소화할 수 있다. According to the present invention, there is no need for a separate vertical reinforcement for separating the upper and lower pressure connecting plates 2 and 3 constituting the PHC pile connector. Therefore, the thickness of the PHC pile connector can be made very thin, thereby minimizing the amount of steel required.
또한, 일측 PHC 파일(1a) 및 타측 PHC 파일(1b)의 이음면에 각각 미리 볼트 체결된 상하부 지압연결판(2, 3)을 날개판(21, 31)이 상호 엇갈리도록 배치한 후 사이에 형성된 고정홀(H)에 전단고정핀(4)을 삽입하는 간단한 공정으로 PHC 파일 연결구를 시공할 수 있다. 따라서 용접 공정 없이 간단하게 상하 이웃하는 PHC 파일(1a, 1b)을 연결할 수 있다. 아울러 PHC 파일(1a, 1b)의 연결 전에 미리 볼트를 체결하므로, 볼트와의 간섭이 없이 PHC 파일(1a, 1b) 연결 작업을 쉽게 진행할 수 있다. In addition, the upper and lower acupressure connecting plates (2, 3) bolted to the joint surfaces of the one side PHC pile (1a) and the other side PHC pile (1b) respectively arranged so that the wing plates (21, 31) to cross each other formed between PHC pile connector can be constructed by a simple process of inserting the shear fixing pin (4) into the fixing hole (H). Therefore, it is possible to simply connect the upper and lower neighboring PHC piles 1a and 1b without the welding process. In addition, since the bolt is fastened before the connection of the PHC files 1a and 1b, the connection work of the PHC files 1a and 1b can be easily performed without interference with the bolts.
뿐만 아니라 PHC 파일 연결구에서 좌굴되는 부재가 없다. 그리고 콘크리트와 동일한 형상 및 면적을 갖는 상하부 지압연결판(2, 3)에 의해 응력 전달이 직접 이루어지므로 지압 응력 분포가 매우 균등하여 응력 집중이 없으며, 내력이 매우 커 PHC 파일 본체에 고강도 콘크리트를 사용하더라도 응력 전달에 전혀 문제가 없다.In addition, there is no buckling member at the PHC pile end. In addition, since the stress is directly transferred by the upper and lower pressure connecting plates (2, 3) having the same shape and area as the concrete, the stress distribution is very uniform, so there is no stress concentration. Even if there is no problem in stress transmission.
나아가 도 9와 같이, 전단고정핀(4)의 횡단면(원형) 전단이 아니라 종단면(직사각형)의 전단에 의해 지지되므로, 상하부 지압연결판(2, 3)의 날개판(21, 31)의 경계부에서 지지내력이 매우 높다. Furthermore, as shown in FIG. 9, the edges of the wing plates 21 and 31 of the upper and lower acupressure connecting plates 2 and 3 are supported by the front end of the longitudinal section (rectangular) rather than the cross section (circular) front end of the shear fixing pin 4. The bearing strength is very high at.
또한, 상하부 PHC 파일(1a, 1b)에 접합되는 PHC 파일 연결구를 동일한 형상으로 제작할 수 있으므로 제작 및 관리 효율이 우수하고, 현장 조립시 작업 관리가 용이하다. In addition, since the PHC pile connector connected to the upper and lower PHC piles 1a and 1b can be manufactured in the same shape, the manufacturing and management efficiency is excellent, and the work management during the field assembly is easy.
도 10에 도시된 바와 같이, 상기 지압연결판(2, 3)의 날개판(21, 31)에는 PHC 파일(1a, 1b)의 이음면에 볼트(B)를 체결하여 고정하기 위한 관통공(212, 312)이 관통 형성되고, 상기 관통공(212, 312)의 입구 측에는 볼트 헤드가 타측 PHC 파일(1b)의 이음면에 밀착되어 지지되는 깊이로 삽입되어 걸리는 확장공(213, 313)이 형성되도록 구성할 수 있다. As shown in FIG. 10, through-holes 212 for fastening and fixing bolts B to joint surfaces of PHC piles 1a and 1b are formed on wing plates 21 and 31 of the acupressure connecting plates 2 and 3. , 312 is formed to penetrate through the inlet side of the through hole (212, 312) so that the expansion head (213, 313) is inserted into the depth to be supported in close contact with the joint surface of the other PHC pile (1b) Can be configured.
상기 관통공(212, 312)은 상하부 지압연결판(2, 3)의 날개판(21, 31)을 각각 일측 PHC 파일(1a) 및 타측 PHC 파일(1b)에 볼트 결합하기 위한 것이다. The through holes 212 and 312 are for bolting the wing plates 21 and 31 of the upper and lower pressure connecting plates 2 and 3 to the one side PHC pile 1a and the other side PHC pile 1b, respectively.
상기 관통공(212, 312)의 입구측 단부에 확장공(213, 313)이 형성되면, 확장공(213, 313)에 볼트(B)의 헤드가 수용된다. 따라서 날개판(21, 31)의 외측으로 볼트(B)가 돌출되지 않아 PHC 파일 연결구의 전체 두께를 최소화할 수 있다. 즉, 상하부 지압연결판(2, 3)의 두께의 합이 곧 PHC 파일 연결구 전체의 두께와 동일하게 된다.When the expansion holes 213 and 313 are formed at the inlet end portions of the through holes 212 and 312, the heads of the bolts B are accommodated in the expansion holes 213 and 313. Therefore, the bolt (B) does not protrude to the outside of the wing plate (21, 31) can minimize the overall thickness of the PHC pile connector. That is, the sum of the thicknesses of the upper and lower acupressure connecting plates 2 and 3 becomes equal to the thickness of the entire PHC pile connector.
상기 날개판(21, 31)에 형성되는 확장공(213, 313)은 삽입되는 볼트 헤드가 각각 타측 PHC 파일(1b)의 이음면 및 일측 PHC 파일(1a)의 이음면에 밀착되어 지지되는 깊이로 형성될 수 있다. The expansion holes 213 and 313 formed in the wing plates 21 and 31 are formed to have depths at which the bolt heads to be inserted are in close contact with the joint surface of the other side PHC pile 1b and the joint surface of one side PHC pile 1a, respectively. Can be.
이에 따라 볼트 헤드가 PHC 파일(1a, 1b)의 선단에 밀착되어 볼트(B)의 움직임이 구속되므로, 항타 등 외부 진동이나 충격에 의해 볼트(B)가 풀리는 것을 원천적으로 방지할 수 있다.As a result, the bolt head is in close contact with the tip ends of the PHC piles 1a and 1b and the movement of the bolt B is constrained, thereby preventing the bolt B from being loosened due to external vibration or impact such as driving.
와셔가 있는 경우, 확장공(213, 313)의 깊이는 와셔의 두께와 볼트 헤드의 두께를 합한 길이로 제작함이 바람직하다. If there is a washer, the depth of the expansion holes (213, 313) is preferably made of the sum of the thickness of the washer and the thickness of the bolt head.
도 11은 외측의 연결링에 의하여 결합된 상하부 지압연결판을 도시하는 평면도이다.Figure 11 is a plan view showing the upper and lower shiatsu connecting plate coupled by an outer connection ring.
도 11에 도시된 바와 같이, 상기 지압연결판(2, 3)의 날개판(21, 31)은 날개판(21, 31)의 내측 또는 외측에 형성된 연결링(23, 33)에 의해 상호 연결될 수 있다. As shown in FIG. 11, the wing plates 21 and 31 of the acupressure connecting plates 2 and 3 may be interconnected by connecting rings 23 and 33 formed inside or outside the wing plates 21 and 31. Can be.
상기 지압연결판(2, 3)의 각 날개판(21, 31)은 볼트(B)에 의해 PHC 파일(1a, 1b) 단부면에 결합될 수 있다. 그런데 복수의 날개판(21, 31)이 서로 분리되어 있으면 날개판(21, 31)을 정확한 각도로 결합하기 어렵다. 그리고 볼트(B) 체결시 볼트 회전력에 의해 날개판(21, 31)이 회전하여 날개판(21, 31) 사이의 공간부(22, 32) 형상이 날개판(21, 31)의 형상과 달라져 타측 지압연결판(2, 3)의 날개판(21, 31)이 공간부(22, 32)에 삽입되기 곤란할 수 있다. Each vane plate 21, 31 of the acupressure connecting plate (2, 3) may be coupled to the end surface of the PHC pile (1a, 1b) by a bolt (B). However, when the plurality of wing plates 21 and 31 are separated from each other, it is difficult to combine the wing plates 21 and 31 at an accurate angle. When the bolt B is fastened, the wing plates 21 and 31 are rotated by the bolt rotation force so that the shape of the space portions 22 and 32 between the wing plates 21 and 31 is different from that of the wing plates 21 and 31. The wing plates 21 and 31 of the other acupressure connecting plates 2 and 3 may be difficult to be inserted into the spaces 22 and 32.
따라서 복수의 날개판(21, 31)을 연결링(23, 33)으로 연결하여 일체화함으로써, 조립 작업 및 자재 관리를 용이하게 할 수 있다.Therefore, by assembling and connecting the plurality of wing plates 21 and 31 with the connection rings 23 and 33, assembling work and material management can be facilitated.
아울러 두 파일의 조립을 용이하게 하기 위해 일측 PHC 파일(1a)의 날개판(21)과 타측 PHC 파일(1b)의 날개판(31) 사이에 소정의 간격이 존재하더라도 연결링(23, 33)이 두 PHC 파일(1a, 1b)의 중심이 일치하도록 하는 가이드 역할을 할 수 있다. In addition, even if there is a predetermined distance between the wing plate 21 of the one side PHC pile (1a) and the wing plate 31 of the other side PHC pile (1b) to facilitate the assembly of the two pile connection ring (23, 33) It can serve as a guide to match the center of these two PHC files (1a, 1b).
상기 연결링(23, 33)이 날개판(21, 31)의 내측에 결합되는 경우, 연결링(23, 33)의 내주면은 중공 형상인 PHC 파일(1a, 1b)의 내주면과 일치되도록 형성할 수 있다. When the connection rings 23 and 33 are coupled to the inside of the wing plates 21 and 31, the inner circumferential surfaces of the connection rings 23 and 33 may be formed to coincide with the inner circumferential surfaces of the hollow PHC piles 1a and 1b. Can be.
도 11에는 연결링(23, 33)이 날개판(21, 31)의 외측에 결합되는 실시예가 도시된다. 11 shows an embodiment in which the connection rings 23 and 33 are coupled to the outside of the wing plates 21 and 31.
일반적으로 PC 너트(11)는 콘크리트 살 두께 중앙에서 외측으로 편심되게 형성되므로, 연결링(23, 33)은 상대적으로 공간적 여유가 있는 날개판(21, 31) 내측에 구비되는 것이 바람직하다. 그러나 파일 지름이 충분히 큰 경우 등 필요에 따라 도 11에 도시된 바와 같이 날개판(21, 31)의 외측에 연결링(23, 33)을 형성할 수도 있다. 이때, 고정홀(H)은 연결링(23, 33)을 관통하여 형성된다. In general, since the PC nut 11 is formed to be eccentrically outward from the center of the thickness of the concrete flesh, the connection rings 23 and 33 are preferably provided inside the wing plates 21 and 31 having a relatively spatial margin. However, when the pile diameter is sufficiently large, as shown in FIG. 11, the coupling rings 23 and 33 may be formed outside the wing plates 21 and 31 as necessary. At this time, the fixing hole (H) is formed through the connecting rings (23, 33).
또한, 도면에는 도시되지 않았으나 연결링(23, 33) 부분을 PHC 파일(1a, 1b)의 외주면 외부로 돌출되도록 형성할 경우, 파일 접합부에서 파일 지지력을 향상시킬 수 있다.In addition, although not shown in the drawings, when the connection rings 23 and 33 are formed to protrude to the outside of the outer circumferential surface of the PHC piles 1a and 1b, the pile supporting force may be improved at the pile joint.
상기 연결링(23, 33)은 두께가 날개판(21, 31)의 1/2로 형성되어, 결합되는 지압연결판(2, 3)의 연결링(23, 33)과 겹쳐지도록 구성할 수 있다. The connecting rings 23 and 33 may be formed to have a thickness of 1/2 of the wing plates 21 and 31 so as to overlap the connecting rings 23 and 33 of the acupressure connecting plates 2 and 3 to be joined. have.
이에 따라 상기 연결링(23, 33)을 단턱부 형상으로 형성함으로써, 상하 지압연결판(2, 3)의 연결링(23, 33)이 서로 맞물리도록 구성할 수 있다. Accordingly, by forming the connecting rings 23 and 33 in a stepped shape, the connecting rings 23 and 33 of the upper and lower pressure connecting plates 2 and 3 may be configured to engage each other.
그러면 일측 지압연결판(2, 3)의 연결링(23, 33)과 타측 지압연결판(2, 3)의 연결링(23, 33)이 서로 밀착되어 PHC 파일 연결구 두께와 동일하게 형성 가능하다.Then, the connection rings 23 and 33 of the one side acupressure connection plates 2 and 3 and the connection rings 23 and 33 of the other acupressure connection plates 2 and 3 are closely attached to each other to form the same thickness as the PHC pile connector. .
이에 날개판(21, 31) 뿐 아니라 연결링(23, 33) 부분에서도 파일 하중을 전달할 수 있다.Thus, the pile load can be transmitted not only in the blade plates 21 and 31 but also in the connection rings 23 and 33.
이 경우에도 PHC 파일 연결구를 구성하는 한 쌍의 지압연결판(2, 3)은 형상이 동일하므로, 한 가지 타입의 지압연결판(2, 3)만 생산하면 된다. Even in this case, since the pair of acupressure connecting plates 2 and 3 constituting the PHC pile connector have the same shape, it is only necessary to produce one type of acupressure connecting plates 2 and 3.
또한, 상하부 PHC 파일(1a, 1b)에 각각 동일한 형상의 지압연결판(2, 3)이 결합되므로, 현장 작업 및 관리가 용이하다.In addition, since the acupressure connecting plates 2 and 3 having the same shape are respectively coupled to the upper and lower PHC piles 1a and 1b, it is easy to perform field work and management.
본 발명의 PHC 파일 연결구는 두께를 매우 얇게 구성할 수 있어 소요 강재량을 최소화할 수 있고, 용접 공정 없이 간단하게 이웃하는 PHC 파일을 연결할 수 있어 안전성이 우수하다는 점에서 산업상 이용 가능성이 있다.PHC pile connector of the present invention can be configured to a very thin thickness can minimize the amount of steel required, there is an industrial use in that the safety is excellent because it can simply connect the neighboring PHC file without a welding process.
