이러한 조건을 만족시키기 위하여 다양한 제품을 개발.생산하여 시공해 왔으며 그러한 노력은 앞으로도 계속될 것이다.In order to satisfy these conditions, various products have been developed, produced and constructed, and such efforts will continue.
그러나 이러한 노력은 차량이 주행하는 차도부에 극한되어져 왔으며 사람들이 통행하는 보도부에는 소홀해 왔던 것이 사실이다.However, these efforts have been limited to the roadway where the vehicle is driven and neglected in the sidewalk where people pass.
기존 교량의 경우 보도부에 신축이음장치가 미설치되었거나 앵커을 이용하여 설치되었으며 이러한 경우 우수의 침수에 의한 교좌장치의 부식 및 기능저하, 교대 및 교각의 콘크리트에 백화현상 및 균열이 발생하였고 토사 및 이물질이 신축이음부에 퇴적되어 신축작용에 커다란 장애가 발생되어 왔다.In case of existing bridges, expansion joints are not installed in the sidewalks or installed using anchors.In this case, corrosion and deterioration of the bridges due to flooding of rainwater, bleaching and cracking of concretes in bridges and bridges, and new soil and foreign materials It has been deposited on the joints and has caused a great deal of distraction.
종래 신축이음장치는 도 1 내지 도 3에 도시된 것과 같이, 그 단면이 凹자형상으로 되고 전면 중간에는 원형의 홈이 길이방향으로 길게 형성된 고무홀더(12)를 가지며, 중간 연결부 하단에는 수개소 앵커홀(13)이 천공된 신축플레이트(5)와, 상기 양 고무홀더(12)에 삽입되는 고무(6)와, 상기 신축플레이트(5)의 앵커홀(13)에 나삽되는 일정길이의 앵커볼트(7)와, 내부에 나선이 형성되고 주변에는 나비형의 돌기가 2 내지 4개소 일정길이 돌출되어 상기 앵커볼트(7)와 나삽되고 본체는 콘크리트(4)에 매설되는 앵커너트(9)와, 상기 앵커볼트(7)의 외부에서 상기 앵커너트(9)와 상기 신축플레이트(5)의 앵커홀(13)간을 연결하는 카바로드(11)로 구성되어 있다.1 and 3, the conventional expansion joint device has a rubber holder 12 whose cross section is U-shaped and has a circular groove formed in a longitudinal direction in the middle of the front, and several places at the bottom of the intermediate connection portion. The anchor plate 13 has a perforated stretch plate 5, the rubber 6 is inserted into the two rubber holder 12, and the anchor of a predetermined length that is screwed into the anchor hole 13 of the expansion plate 5 A bolt (7) and a spiral is formed therein and a butterfly-shaped protrusion protrudes 2 to 4 locations around the anchor bolt (7) and the anchor nut (9) embedded in the concrete (4) And a cover rod 11 that connects the anchor nut 9 and the anchor hole 13 of the expansion plate 5 to the outside of the anchor bolt 7.
여기서 상기 신축플레이트(5)는 알루미늄합금으로 되는 것이 바람직할 것이다.It is preferable that the expansion plate 5 be made of an aluminum alloy.
그리고 종래 신축이음장치의 설치공정에 대해 도4a 내지 도4c에 의거 설명하면, 먼저 도로나 교량의 연결부위를 일정길이와 높이로 절개하여 개구부(2)를 형성시킨다.4A to 4C, the installation process of the conventional expansion joint device is described. First, the opening portion 2 is formed by cutting the connection portion of the road or the bridge to a predetermined length and height.
이후 신축이음장치를 구성하는 신축플레이트(5)의 앵커홀(13)에 앵커볼트(7)를 끼운 다음 위에서 너트(10)를 나사결합함과 더불어, 상기 앵커볼트(7)의 외주에 하부에서 카바로트(11)를 끼운 후 앵커볼트(7)의 하부에는 앵커너트(9)를 나삽하여 가결합을 시킨다.After inserting the anchor bolt (7) in the anchor hole (13) of the expansion plate (5) constituting the expansion joint device and then screw the nut (10) from the top, at the lower periphery of the anchor bolt (7) After inserting the cabarot (11) to the lower part of the anchor bolt (7) by screwing the anchor nut (9) to the temporary coupling.
또한 이렇게 가결합된 신축이음장치를 구성하는 2세트의 신축플레이트(5)상면에 평판(16)을 올리고 수개소 가용접(Tag Welding)하여 설치세트를 구성하여, 상기 설치세트를 개구부(2)에 올려서 평판 양옆에 서포트(14)를 끼워서 도로면과 높이를 맞춘다In addition, by mounting the flat plate 16 on the upper surface of the two sets of expansion plates (5) constituting the expansion joints are thus combined and welded several places (tag welding) to configure the installation set, the installation set is the opening (2) Mount the support (14) on both sides of the plate and align the height with the road surface.
이후 상기 앵커너트(9)와 앵커볼트(7)의 외주 카바로트(11)일정깊이 까지 묻히도록 개구부(2)에 콘크리트(4)타설을 하여 메꾼다.Since the anchor nut (9) and the anchor bolt (7) to the outer periphery cabarot (11) to be buried up to a certain depth, the concrete (4) is poured into the opening (2) to fill.
다음 상기 콘크리트가 응고후 평판(16)을 떼어내고 너트(10)를 풀어서 신축 플레이트(5)를 들어낸 다음 앵커볼트(7)를 풀어서 제거한다.Next, after the concrete is solidified, the plate 16 is removed and the nut 10 is removed to lift the expansion plate 5, and then the anchor bolt 7 is removed by removing.
또 상기 카바로드(11)의 상면에 덮개(17)를 씌우고 도로포장용 아스팔트(1)로 포장을 완료한다.In addition, the cover 17 is put on the upper surface of the kava rod 11, and the pavement is completed by the asphalt pavement (1).
다음 도 2에 도시된 것과 같이, 상기 개구부(2)의 윗부분 아스팔트(1)를 일정면적 절개하고, 상기 신축이음장치와 아스파트(1)의 사이에는 완충타르(3)를 쳐 마감한다.Next, as shown in FIG. 2, a predetermined area of the asphalt 1 of the upper part of the opening 2 is cut, and a buffer tar 3 is finished between the expansion joint and the aspart 1 to finish.
이후 신축이음장치의 설치는, 상기 덮개(17)를 벗기고 카바로드(11)내에 앵커볼트(7)를 나사결합하여 하단이 앵커너트(9)에 견고히 나삽되도록 설치하고, 상기 앵커볼트(7)의 상단에 신축 플레이트(5)의 앵커홀(13)를 끼우고, 위에서 너트(10)로 나사결합하면 완료된다.Since the expansion joint is installed, the cover 17 is removed and the anchor bolt 7 is screwed into the cover rod 11 so that the lower end is firmly screwed into the anchor nut 9, and the anchor bolt 7 is installed. Insert the anchor hole 13 of the elastic plate 5 at the top of, and screwed with the nut 10 from above is completed.
다음 신축이음장치의 설치가 끝난 후, 신축이음장치의 凹자형 홈 부위에서 고무(6) 또는 모르타르등을 채워서 설치를 완성한다.After the installation of the expansion joint is completed, the installation is completed by filling rubber 6 or mortar in the U-shaped groove of the expansion joint.
한편 상기 구성중 앵커너트(9)의 주변에는 도 5에 도시된 것과 같이, 상기보강철근(15)을 설치하는 것도 선호되며, 상기 앵커너트(9)에 앵커볼트(7)를 체결하기 전에 앵커너트(9)에 에폭시를 주입하고 앵커볼트(7)를 체결함이 보다 바람직하다.Meanwhile, as shown in FIG. 5, it is also preferable to install the reinforcing reinforcing bars 15 around the anchor nut 9 in the configuration, and anchor the anchor bolt 7 before fastening the anchor bolt 7 to the anchor nut 9. More preferably, epoxy is injected into the nut 9 and the anchor bolt 7 is fastened.
따라서 상기 신축이음장치는 2개의 신축플레이트(5)로 형성되어 각각의 신축플레이트(5)가 도로의 연결부 끝단에 각각 설치되고, 각각의 신축플레이트(5)사이의 고무(6)가 신축을 흡수하면서 이음매의 틈을 메꿔주게 되며, 상기 고무(6)는 2개의 신축 플레이트(5)의 고무홀더(12)에 삽입되는 구조이므로 설치후에도 외부에서 교체가 가능하다.Therefore, the expansion joint is formed of two expansion plates (5) so that each expansion plate (5) is installed at each end of the road connection, the rubber 6 between each expansion plate (5) absorbs the expansion While filling the gap of the seam, the rubber (6) is inserted into the rubber holder 12 of the two expansion and contraction plates (5) can be replaced from the outside even after installation.
또한 상기 신축 플레이트(5)는 앵커볼트(7)를 통해 앵커너트(9)에 의하여 지지되게 되는데, 상기 앵커너트(9)는 주변의 나비형의 돌기가 돌출되어 있어서 주변 콘트리트(4)와 견고히 결합되게 된다.In addition, the expansion plate (5) is supported by the anchor nut (9) through the anchor bolt (7), the anchor nut (9) is firmly with the peripheral concrete (4) because the protruding butterfly projections protrude To be combined.
또 상기 신축 플레이트(5)를 알루미늄합금으로 제작하면 내마모성 및 내충격성이 좋아지며, 특히 차량 탑승자에게 충격을 주지 않아 승차감도 향상시킬 수 있게 된다.In addition, when the expansion plate 5 is made of aluminum alloy, wear resistance and impact resistance are improved, and in particular, the riding comfort can be improved without impacting the occupant of the vehicle.
또한 상기 가결합된 설치세트상태에서 앵커너트(9)의 전부와 앵커볼트(7)의 외주의 카바로드(11)의 일부가 콘크리트(4)에 매설되므로 추후 앵커너트(9)에 앵커볼트(7)을 재체결시 세팅이 정확하며, 상기 앵커너트(9)가 콘크리트(4)와 견고히 결합되어 별도의 보강철근이 필요 없으며, 상기 신축플레이트(5)와 아스팔트(1)사이에 완충타르(15)가 아스팔트(1)의 깨어짐을 방지하게 된다.In addition, since all of the anchor nut 9 and a part of the outer cover bar 11 of the outer circumference of the anchor bolt 7 are embedded in the concrete 4 in the installed set state, the anchor bolt 9 is later anchored to the anchor nut 9 ( 7) The setting is accurate when re-fastening, the anchor nut (9) is firmly coupled with the concrete (4) does not require a separate reinforcing bar, the cushioning tar (5) between the expansion plate (5) and asphalt (1) 15) prevents the cracking of the asphalt 1.
또 아스팔트(1)포장후 적정부위를 절개하여 신축이음장치를 설치하므로 모서리의 아스팔트(1)도 충분한 다짐을 받아서 견고하게 설치되게 된다.In addition, the asphalt (1) is paved by cutting the appropriate portion and then installed expansion joints because the asphalt (1) of the corner is also firmly installed with enough compaction.
도로의 여건상 지반이 약하거나 보강이 필요한 경우에는 앵커너트(9)의 돌출돌기를 키우거나, 앵커너트(9)의 상하에 보강철근(15)을 용접하여 매설하므로써 충분한 지지강도를 얻을 수 있게 되며, 상기 앵커너트(9)에 에폭시를 주입하고 앵커볼트(7)를 나삽하면 앵커너트내의 에폭시가 굳으면서 볼트/너트의 체결을 공고히 할 뿐만 아니라 볼트 밑부분의 너트에서 틈매꿈을 하고 높이를 유지하게 된다.If the ground is weak due to road conditions or reinforcement is required, sufficient support strength can be obtained by increasing the protrusions of the anchor nut 9 or by welding and reinforcing the reinforcing bar 15 above and below the anchor nut 9. When the epoxy is injected into the anchor nut (9) and the bolt is inserted into the anchor bolt (7), the epoxy in the anchor nut hardens to tighten the bolt / nut, as well as tightening the nut at the bottom of the bolt and increasing the height. Will be maintained.
그런데 이와 같이 구성된 신축이음장치는, 보도부에 추가로 설치하고자 할 경우에 상기 앵커볼트(7)의 설치과정에서 앵커너트(9)를 삽입하기 위해서는 상기 아스팔트와 콘크리트를 10 - 15cm 이상 깨어내어야만 시공이 가능하기 때문에 구조물에 손상을 줄 수 있는 문제점이 있었다.By the way, when the expansion joint configured in this way, if you want to install in addition to the sidewalk in the installation process of the anchor bolt (7) in order to insert the anchor nut 9, the asphalt and concrete must be broken more than 10-15cm construction Since this is possible there was a problem that can damage the structure.
또 상기 앵커볼트와 앵커너트를 설치하기 위하여 가조립한 상태에서 콘크리트를 타설한 다음, 다시 해체한 후에 콘크리트를 양생하고 반복하여 설치하는 번거로움을 반복하여 시공하게 되는 문제점이 있었다.In addition, after installing concrete in the assembled state in order to install the anchor bolt and the anchor nut, and then dismantled again, there was a problem in that the construction of repeatedly curing the hassle to install concrete repeatedly.
또한 종래의 신축이음장치는 설치공정이 복잡하여 경제적인 측면에서 시공비가 높게되는 문제점이 있었다.In addition, the conventional expansion joint device has a problem in that the installation cost is complicated in terms of the economical construction process.
이에 본 발명은 상기와 같은 제반문제점을 해소하기 위해 안출된 것으로, 구조물에 손상을 주지 않고 신뢰성을 줄 수 있으면서도 간단한 시공과 저렴한 비용으로 시공할 수 있도록 된 교량이음매의 보도부용 신축이음장치와 그 설치공법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and can be installed at a low cost and simple construction and low-cost expansion joints for the bridge joints and its installation without damaging the structure The purpose is to provide a process.
