Description
본 발명은, 교량용 신축이음장치용에 관한 것이다.The present invention relates to an expansion joint device for bridges.
교량 구조물은 온도변화 및 하중에 따라서 팽창하고 수축된다. 그러므로 일정한 길이 이상으로 건설되는 교량 구조물, 특히 상부구조물은 일정 길이마다 적정한 간격(일반적으로 "유간"이라 함)을 가지고 있다. 이러한 유간에는 자세히 후술할 신축이음장치가 설치되는데, 신축이음장치로 인해 교량의 상부구조물이 손상되는 것이 방지되고, 차량이 원활하게 주행한다.Bridge structures expand and contract in response to temperature changes and loads. Therefore, bridge structures, especially superstructures, that are built over a certain length, have a reasonable spacing (generally called "gap") for each length. Such a clearance is provided with expansion joints to be described in detail below, the expansion joint is prevented from damaging the upper structure of the bridge, the vehicle runs smoothly.
그러나 무수히 공지된 교량용 신축이음장치는 상부구조물의 수축 및 팽창에 따라 유연하게 신축되기는 하나, 물의 침투를 저지하는데는 구조적으로 취약하다. 결국, 종래에는 이물질, 특히 물이 유간으로 침투하여 교량 하부구조물인 교좌장치에 스며들므로써, 교량 하부구조물을 부식시키고 그 수명을 단축시키게 되는 문제점을 야기시킨다.However, a myriad of known expansion joints for bridges are flexibly stretched according to the contraction and expansion of the superstructure, but are structurally weak in preventing the penetration of water. As a result, in the past, foreign matter, in particular, water penetrates into the oil gap and penetrates into the bridge device, which is a bridge substructure, causing a problem of corroding the bridge substructure and shortening its lifespan.
또한, 제품의 높이가 높은 단점이 있으며, 별도의 금형 작업 없이는 제품을 생산할 수 없는 단점이 있다. 또한, 금형에 의해 신축이음장치가 일체로 제조되는 것이 보통이므로 부분적인 유지보수 작업이 어렵다는 단점이 있다.In addition, there is a disadvantage that the height of the product is high, there is a disadvantage that can not produce the product without a separate mold operation. In addition, since the expansion joint is usually manufactured integrally by a mold, there is a disadvantage in that partial maintenance work is difficult.
따라서, 본 발명의 목적은, 신축작용을 원활하게 수행하면서도 이격간격 사이로 물을 포함한 이물질이 침투되는 것을 효과적으로 방지할 수 있도록 한 교량용 신축이음장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide an expansion joint device for a bridge that can effectively prevent the foreign matter, including water, penetrates between the separation intervals while performing the stretching operation smoothly.
또한, 금형이 없이도 제조할 수 있어 부분적인 유지보수 작업이 수월하며, 그라우팅 수용부의 깊이에 맞추어 적절하게 높이를 조절할 수 있도록 한 교량용 신축이음장치를 제공하는 것이다.In addition, it is possible to manufacture without a mold to facilitate partial maintenance work, and to provide a new expansion joint for the bridge to adjust the height according to the depth of the grouting receiving portion.

이 때, 만곡부(42)는 물의 배수를 위해 유간(H)을 하측을 향해 거의 "Ｕ"자 형태로 굴곡되어 있다. 이 때, 굴곡 형상은 반드시 "Ｕ"자 형태를 취할 필요는 없으며, "Ｗ"나 "Ｖ"자 형태를 포함하여 여타의 굴곡 곡선 형태를 이룰 수 있다. 그리고, 상호 연설되는 각 신축이음장치 중 최후에 배치되는 신축이음장치의 만곡부(미도시)에는 배수장치(미도시)를 설치하는 것이 바람직하다.At this time, the curved portion 42 is bent in a substantially "Ｕ" shape toward the lower side of the oil gap H for draining the water. At this time, the bent shape does not necessarily have to take the shape of "Ｕ", but may have other bend curve forms including the "Ｗ" or "Ｖ" shape. In addition, it is preferable to install a drainage device (not shown) in the curved portion (not shown) of the expansion joint device disposed last among the expansion joint devices that are mutually addressed.
이물차단부재(40)는 전체적으로 판상으로 형성되며, 내부에는 도 2에 확대 도시된 바와 같이, 판상의 보강부재(47)가 개재되어 있다. 보강부재(47)는 석면 및 섬유재질 등으로 형성될 수 있으며, 잦은 신축으로 인해 이물차단부재(40)가 부분적으로 끊어지는 것을 방지한다. 보강부재(47)는 압축성형 혹은, 프레스가황 등에 의해 이물차단부재(40)에 일체로 형성될 수 있다.The foreign material blocking member 40 is formed in a plate shape as a whole, and as shown enlarged in FIG. 2, a plate-shaped reinforcing member 47 is interposed therebetween. The reinforcing member 47 may be formed of asbestos, a fiber material, or the like, and prevents the foreign material blocking member 40 from being partially broken due to frequent stretching. The reinforcing member 47 may be integrally formed with the foreign material blocking member 40 by compression molding or press vulcanization.
한편, 본 발명에서는 이물차단부재(40)를 포함하여, 상판부재(30,30a) 및 지지부(20,20a)를 일체로 결합시키는 결합수단(참조부호 생략)을 더 포함하고 있다.결합수단은, 별도의 금형이 없이도 본 신축이음장치를 제조할 수 있다는 효과를 제공한다.On the other hand, the present invention further comprises a coupling means (not shown) including the foreign matter blocking member 40 to integrally couple the upper plate members 30 and 30a and the support portions 20 and 20a. It provides the effect that the expansion joint can be manufactured without a separate mold.
결합수단은, 각 상판부재(30,30a), 각 결합부(44,44a) 및 각 지지부(20,20a)의 판면에 동축선을 가지고 일체로 관통형성된 복수의 볼트공(31,41,21)과, 볼트공(31,41,21)으로 삽입되는 고정스크루(45)를 포함한다. 이처럼, 각 상판부재(30,30a), 각 결합부(44,44a) 및 각 지지부(20,20a)가 스크루 결합될 수 있도록 함으로써, 부분적인 유지 보수작업이 용이하게 된다.The coupling means includes a plurality of bolt holes 31, 41 and 21 integrally formed through the coaxial lines on the plate surfaces of the upper plate members 30 and 30a, the engaging portions 44 and 44a and the supporting portions 20 and 20a. And a fixing screw 45 inserted into the bolt holes 31, 41, and 21. As such, by allowing the respective upper plate members 30 and 30a, the respective coupling parts 44 and 44a and the respective support parts 20 and 20a to be screwed together, partial maintenance work is facilitated.
이러한 구성을 갖는 신축이음장치를 설치하는 과정을 도 5를 참조하여 설명하면 다음과 같다.A process of installing the expansion joint having such a configuration will be described with reference to FIG. 5 as follows.
