Description

신축이음장치{EXPANSION JOINT DEVICE}Expansion joints {EXPANSION JOINT DEVICE}

본 발명은 신축이음장치에 관한 것으로, 더욱 상세하게는 도로의 노면이나 교량 상판에 설치되는 신축이음장치에 관한 것이다.The present invention relates to an expansion joint device, and more particularly to an expansion joint device installed on the road surface or bridge top plate.

교량구조물의 교량상판(슬래브)은 하중, 온도변화, 콘크리트 크리프, 건조수축, 프리스트레싱 등에 의해 변형(팽창 및 수축)이 발생하게 되는데, 이러한 변형을 방지하기 위하여 교량상판(슬래브)끼리는 적당한 간격으로 유지시키면서 이격시켜 주게 되고, 이격된 공간에는 교량용 신축 이음 장치를 설치하여 차량이 원활하게 주행(통과)하도록 하고 교량상판이 손상되는 것을 방지하게 된다.The bridge deck (slab) of the bridge structure is deformed (expanded and contracted) due to load, temperature change, concrete creep, dry shrinkage, prestressing, etc., and the bridge decks (slabs) are maintained at appropriate intervals to prevent such deformation. While being spaced apart from each other, the spaced space is provided with a new expansion joint for the bridge so that the vehicle can run smoothly (pass) and prevent the bridge top plate from being damaged.

상기 교량용 신축 이음 장치의 이음부에는 변형에 유동적으로 대처하기 위하여 빗 모양(또는 손가락 모양)의 핑거를 갖는 핑거 플레이트가 널리 채용되고 있다.Finger plates having comb-like (or finger-like) fingers are widely employed at joints of the expansion joints for bridges in order to flexibly cope with deformation.

국내 특허 10-0658535호에는 하판의 수평면부 하부에 현장 여건에 맞추어 높이 조절이 가능한 구조로 수직 또는 경사지게 설치되는 앙카볼트 및 하판의 양측 수평면부에 그 단부가 각각 설치되며, 상기 상판의 핑거부의 틈새로 유입된 우수 및 이물질의 수거를 위한 고무판부재를 포함하여 구성된다. In Korean Patent No. 10-0658535, the end is installed on both horizontal surfaces of the anchor plate and the lower plate, which are installed vertically or inclined in a structure capable of height adjustment in accordance with the site conditions under the horizontal surface of the lower plate, the gap between the finger portion of the upper plate It consists of a rubber plate member for the collection of rainwater and foreign matter introduced into.

종래 핑거형, 웨이브식 파형, 톱니형-이물질 유입, 우수 및 이물질 수거용 고무판재 부착, 차량 통과시 운전자는 이격에 따른 소음과 충격진동을 느끼는 단점이 있다. Conventional finger-type, wave-type waveform, saw-tooth-foreign material inflow, rainwater and foreign matters attached to the rubber plate, there is a disadvantage that the driver feels noise and shock vibration due to separation when passing through the vehicle.

이격에 따른 지진감쇄에 취약하고, 종단면에서 기존의 핑거형, 웨이브식 파형, 톱니형태는 상호 양단부 상부판이 이격되어져 있어서 양단의 도로 종단부 상하편차 대응에 미약한 구조이다. It is vulnerable to earthquake attenuation due to separation, and the existing finger-type, wave-shaped, and tooth-shaped in the longitudinal section are weak in responding to the vertical deviation of road ends at both ends because the upper plates of both ends are spaced apart from each other.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

콘크리트를 절개하여 형성되어 서로 마주보는 양측의 콘크리트 노면의 각 단면부(R1,R2)에 각기 제1고정부(2)와 제2고정부(2')를 소정 간격으로 이격시켜 부착하고, 무수축 콘크리트를 타설하여 양생한다. The first fixing part 2 and the second fixing part 2 'are respectively spaced apart at predetermined intervals and attached to the end portions R1 and R2 of the concrete road surface formed by cutting the concrete and facing each other. It cures by pouring shrinkage concrete.

양측 제1,2고정부(2,2')를 관통하여 완충 실린더(8)를 결합한다. 완충 실린더(8)는 한개 또는 여러개일 수 있다. The buffer cylinder 8 is coupled through the first and second fixing parts 2 and 2 'on both sides. The buffer cylinder 8 may be one or several.

완충 실린더(8)가 여러개일 경우 최하부의 완충 실린더(8)는 지지판(46)의 하단을 떠받치도록 결합된다. When there are several buffer cylinders 8, the lowermost buffer cylinder 8 is coupled to support the lower end of the support plate 46.

일부 완충 실린더(8)는 신축탄성부(4)에 관통 결합된다. 즉 신축탄성부(4)의 탄성부재(42), 가스켓(44), 지지판(46)을 관통하여 완충 실린더(8)의 봉체(82)가 결합된다. Some of the buffer cylinders 8 are penetrated by the elastic elastic portion 4. That is, the rod 82 of the shock absorbing cylinder 8 is coupled through the elastic member 42, the gasket 44, and the support plate 46 of the elastic elastic part 4.

따라서 탄성부재(42)와 지지판(46) 사이의 틈새가 생기지 않도록 가스켓(44)이 결합됨으로써 탄성부재(42)의 수축 작동 및 지지판(46)의 상하 슬라이딩 작동시에도 가스켓(44)이 밀착된 상태로 유지됨으로써 수밀성을 갖게 되어 우수 및 이물질의 유입이 방지될 수 있다. Therefore, the gasket 44 is coupled to the gap between the elastic member 42 and the support plate 46 so that the gasket 44 is in close contact even when the elastic member 42 is contracted and the upper and lower sliding operations of the support plate 46 are performed. By being kept in a state to have a water tightness can be prevented the inflow of rainwater and foreign matter.

또한 완충 실린더(8)를 구성하는 봉체(82)의 양단부는 스프링(84)이 지지되며 제1,2고정부(2,2')에 미리 결합된 소켓(86)에 삽입되어 끼움결합된다. In addition, both ends of the rod (82) constituting the buffer cylinder (8) is supported by the spring (84) and is inserted into the socket 86, which is pre-coupled to the first and second fixing parts (2, 2 ') are fitted.

따라서 양측의 콘크리트 노면(R1,R2)이 외부 온도 변화에 따라 수축 또는 신장되는 변화가 발생될 경우 양측 제1,2고정부(2,2')의 간격이 좁혀지거나 벌어지는 경우 스프링(84)의 신축작동이 일어나게 되고 완충부(8)의 봉체(82)는 형상의 변형 없이 안정적으로 지지력을 발휘하게 된다. Therefore, when the concrete road surface (R1, R2) of both sides shrinks or expands in accordance with the external temperature change occurs when the distance between the first and second fixing parts (2,2 ') of both sides is narrowed or widened, The stretching operation occurs and the rod 82 of the shock absorbing portion 8 exhibits a stable bearing force without deformation of the shape.

First and second fixing parts respectively coupled to end portions of both concrete road surfaces and comprising horizontal and vertical plates to be embedded in the ground;
A stretchable elastic part including a plurality of elastic members tightly coupled between the first and second fixing parts, a support plate coupled and supported between each elastic member, and a gasket inserted and coupled between the support plate and the elastic member;
Finishing plate attached to the horizontal piece of the upper portion to cover the elastic elastic portion;
And a buffer cylinder coupled through the plurality of elastic members, the support plate, and the gasket, and penetrated through the vertical plates of the first and second fixing parts.
Each of the first and second fixing parts is formed by protruding the bracket toward the inner side at the corner portion where the horizontal plate and the vertical plate are connected.
The bracket is embedded in non-contraction concrete to be fixed,
The elastic member is
It is a metal plate having a 'U' cross section, and the curved portion is disposed to face upward or downward.
The gasket is a rubber or synthetic resin material in close contact with the support plate and the elastic member, to prevent the inflow of rainwater,
The upper end of the support plate is in contact with the bottom of the closing plate to support the closing plate,
The elastic member is to be spaced apart from the finishing plate so that the curved portion does not touch the finishing plate during the stretching operation of the elastic member,
The buffer cylinder
A rod penetrating the elastic member, the support plate, and the gasket,
Springs elastically supported at both ends of the rod and
It is made of a socket coupled to both rods and the spring is received inside,
The socket is expansion joint device, characterized in that coupled to the first and second fixing parts.
