Description

신축이음장치{EXPANSION JOINT}Expansion joints {EXPANSION JOINT}

본 발명은 구조물, 특히 터널이나 지하차도와 같이 굴곡된 구조물에 적용하여 사용할 수 있고, 설치하고자 하는 현장 상황에 맞추어 적용할 수 있으므로 시공이 용이하고 신속하며, 비용이 경제적인 신축이음장치에 관한 것이다.The present invention can be applied to a structure, in particular bent structures such as tunnels and underground cars, and can be applied according to the site conditions to be installed, and relates to a new expansion joint device is easy, quick and cost-effective construction .

일반적으로 교량 등과 같은 구조물에는 온도변화, 크리프(Creep) 및 건조수축(Shrinkage), 시공오차, 재하 하중, 지진 및 지반의 침하 등의 여러 원인에 의한 변형 응력이 작용된다. In general, structures such as bridges are subjected to deformation stresses caused by various causes such as temperature changes, creep and shrinkage, construction errors, loading loads, earthquakes and ground subsidence.

만약, 이러한 응력이 해방되지 않고 구속되게 된다면 구조물에 균열을 발생시키고 파손시킬 우려가 있으므로, 구조물의 건조시에는 필수적으로 일정구간마다 유격되는 틈새인 이음틈새를 두고 있으며, 이음틈새에는 별도의 신축이음장치를 설치하여 구조물의 변형에 따른 동적거동을 원활히 수용하면서 해당 이음틈새를 폐쇄하도록 하고 있다.If the stress is constrained without being released, there is a risk of cracking and damage to the structure. Therefore, when the structure is constructed, there is a joint gap, which is a gap that is spaced at regular intervals, and there is a separate expansion joint in the joint gap. By installing the device, the joint gap is closed to accommodate the dynamic behavior of the structure.

일 예로 구조물이 교량인 경우, 교량은 하부의 다수개의 교각과, 교각의 상 부에 안착되어 도로를 형성하게 되는 다수개의 상판으로 구성되며, 상판과 상판이 연결되는 부분에는 양쪽 상판의 동적거동을 원활히 수용할 수 있도록 적정 유격 폭으로 이음틈새가 구비되게 된다.For example, when the structure is a bridge, the bridge is composed of a plurality of bridges at the bottom and a plurality of tops that are seated on the top of the bridges to form a road, and the top plate and the top plate are connected to the dynamic behavior of both tops. The gap is provided with a suitable clearance width to accommodate smoothly.

그리고, 이러한 이음틈새를 수평방향으로 연결하여 폐쇄함으로써 상부에서 주행하게 되는 차량이 원활히 주행할 수 있도록 하면서, 빗물이나 각종 이물질이 해당 이음틈새를 통해 유입, 낙하하여 교량의 하부 시설물들을 오염시키거나 부식시키는 것을 방지하기 위하여 신축가능한 신축이음장치가 이음틈새에 설치된다.In addition, by connecting and closing the joint gap in a horizontal direction so that the vehicle running on the upper side can run smoothly, rainwater or various foreign substances flow into and fall through the joint gap to contaminate or corrode the lower facilities of the bridge. Flexible expansion joints are installed in the gaps of the joints to prevent them.

신축이음장치는 구조물의 안전성과 내구성에 직접적인 영향을 미치면서, 구조물의 전체 구성 중에서도 가장 파손 및 교체빈도가 높은 요소이므로 기본적으로 신축기능과 밀폐기능을 완벽하면서 내구성 있게 제공할 수 있어야 함은 물론, 외부 노출시의 자외선이나 각종 화학물질에 대한 저항성도 우수하여야 하고, 신속한 시공이 가능하여 보수시 교통통제 등을 가능한 줄일 수 있어야 한다.Expansion joints have a direct impact on the safety and durability of the structure, and are the most frequently damaged and replaceable elements in the overall structure of the structure. It should be excellent in resistance to ultraviolet rays or various chemicals when exposed to the outside, and it should be possible to reduce the traffic control when repairing.

그런데, 터널이나 지하차도 등의 상부부분이 아치형으로 형성된 경우 소정의 곡률을 갖도록 형성되며, 이러한 아치형상에 일반적인 신축이음장치를 적용할 경우 일정 곡률이상 휘면 부러지므로 시공이 거의 불가능하였다. However, when the upper portion of the tunnel or the underground driveway is formed in an arch shape, the curvature is formed to have a predetermined curvature. When the general expansion joint device is applied to the arch shape, it is almost impossible to bend because it bends over a certain curvature.

이에 과다한 이음시공이 필요하므로 비용이 상승할 뿐만 아니라 작업의 효율성 또한 떨어지는 문제가 있었다.Since excessive joint construction is required, there is a problem that not only the cost rises but also the work efficiency decreases.

본 발명의 목적은 구조물, 특히 터널이나 지하차도와 같이 굴곡된 구조물에 적용하여 사용할 수 있는 신축이음장치를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an expansion joint device which can be applied to a curved structure such as a tunnel or an underground road.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 1은 본 발명의 일 실시예에 따른 신축이음장치의 분해도이고, 도 2는 본 발명의 일 실시예에 따른 신축이음장치의 조립도이다.1 is an exploded view of the expansion joint according to an embodiment of the present invention, Figure 2 is an assembly view of the expansion joint according to an embodiment of the present invention.

도시된 바와 같이 본 발명의 일 실시예에 따른 신축이음장치는 크게 신축수단(10)과 와이어(20) 및 끼움수단(30)이 포함되어 구성된다. As shown, the expansion joint according to an embodiment of the present invention is largely configured to include the expansion means 10 and the wire 20 and the fitting means 30.

신축수단(10)은 중공 형상으로 형성되는데, 양측이 연통되도록 개방되고, 상부면과 하부면이 하부 방향을 향해 구부러지도록, 즉 U 형상으로 형성된다. 이때, 신축수단(10)의 원활한 신축을 위해 상부면이나 하부면 중 어느 하나 또는 둘이 신축 가능하게 형성되는 것이 바람직하며, 곡률을 갖는 구조물에 적용할 수 있도록 일정 곡률이상 휘어질 수 있는 합성수지 재질이나 고무 재질 등으로 형성된다.The stretching means 10 is formed in a hollow shape, both sides are open so as to communicate with each other, and the upper and lower surfaces are bent toward the lower direction, that is, is formed in a U shape. At this time, it is preferable that any one or two of the upper surface or the lower surface is stretchable for smooth expansion and contraction of the stretching means 10, and the synthetic resin material that can be bent more than a certain curvature to be applied to a structure having a curvature or It is formed of a rubber material or the like.

그리고 외면에는 둘 이상의 결합홈(12)이 형성되어 하기에 서술하는 끼움수단(30)의 끼움부(32)가 결합되며, 이러한 끼움부(32)와 접하는 부분에는 다수의 미 끄럼방지돌기(16)가 형성된다.And the outer surface is formed with two or more engaging grooves 12 are coupled to the fitting portion 32 of the fitting means 30 described below, a plurality of non-slip projections 16 in contact with the fitting portion (32) ) Is formed.

한편, 결합홈(12)으로부터 떨어진 위치에는 하기에 서술하는 와이어(20)가 삽입되어 결합되도록 와이어삽입공(14)이 형성된다.On the other hand, the wire insertion hole 14 is formed in the position away from the coupling groove 12 so that the wire 20 described below is inserted and coupled.

이와 같이 중공의 U 형상으로 형성되는 신축수단(10)은 유연한 신축이 가능하므로 터널이나 지하차도 외에 다른 구조물에도 바람직하게 적용될 수 있다. 물론 상부면과 하부면이 평탄한 형태로 형성될 수도 있으나 이러한 경우 상면평탄성이 보다 중요하고 고려되어야 할 보도교량, 경기장 등에 적용될 수 있다.Thus, the expansion means 10 formed in a hollow U shape can be flexibly stretched and can be preferably applied to other structures besides tunnels or underground roadways. Of course, the upper and lower surfaces may be formed in a flat shape, but in this case, the upper surface flatness may be applied to a sidewalk bridge, a stadium, and the like, which should be considered more important.

와이어(20)는 둘 이상의 개수로 신축수단(10)의 개방된 양측방향에 대응되도록 신축수단(10)의 내부, 즉 신축수단(10)에 형성된 와이어삽입공(14)을 통해 삽입되어 배치된다.The wire 20 is inserted into and disposed through the wire insertion hole 14 formed in the expansion means 10, that is, the expansion means 10 so as to correspond to the open bilateral directions of the expansion means 10 in two or more numbers. .

이와 같이 본 발명에서는 와이어(20)를 사용함으로써 신축이음장치(100)가 일정한 강도를 가지면서 구조물에 뒤틀림이나 좌굴이 발생하더라도 이를 견뎌낼 수 있게 된다.Thus, in the present invention by using the wire 20, even if the expansion joint device 100 has a certain strength, even if distortion or buckling occurs in the structure it can withstand this.

또한, 구조물 내의 철근 등에 연결하여 신축이음장치(100)를 안정적으로 지지하도록 다수의 볼트(B), 예를 들어 스타트볼트 등을 신축수단(10)에 구멍을 뚫고 와이어(20)와 연결하여 사용할 수 있다.In addition, a plurality of bolts (B), for example, start bolts, may be drilled in the expansion means 10 to connect the wires 20 to stably support the expansion joint device 100 by connecting to rebars in the structure. Can be.

끼움수단(30)은 결합홈(12)에 결합되는 끼움부(32)가 다수로 형성되고, 신축수단(10)의 상부를 덮도록 배치되어 이음틈새를 폐쇄하게 된다. The fitting means 30 is formed with a plurality of fitting portions 32 coupled to the coupling groove 12, is arranged to cover the upper portion of the expansion means 10 to close the gap.

다수의 끼움부(32)는 상호 접하지 않도록 떨어져 형성되거나, 적어도 말단이 상호 접하지 않도록 형성되며, 이에 따라 곡률을 갖는 구조물에 적용하더라도 원활 하게 동작할 수 있다. 그리고, 끼움부(32)는 결합홈(12)에 결합되는 경우 신축수단(10)에 형성된 다수의 미끄럼방지돌기(16)와 접함으로써 끼움수단(30)이 쉽게 신축수단(10)으로부터 이탈되지 않게 된다.The plurality of fitting portions 32 are formed to be in contact with each other, or at least the ends are formed not to be in contact with each other, and thus can be operated smoothly even when applied to a structure having a curvature. When the fitting portion 32 is coupled to the coupling groove 12, the fitting portion 30 is easily detached from the stretching means 10 by contacting the plurality of non-slip protrusions 16 formed on the stretching means 10. Will not.

물론, 끼움수단(30) 또한 신축수단(10)과 마찬가지로 곡률을 갖는 구조물에 적용할 수 있도록 일정 곡률이상 휘어질 수 있는 합성수지 재질이나 고무 재질 등으로 형성된다.Of course, the fitting means 30 is also formed of a synthetic resin material or rubber material that can be bent over a certain curvature so as to be applied to a structure having a curvature, like the stretching means 10.

도 3은 본 발명의 일 실시예에 따른 신축이음장치의 설치상태도이다. 여기서, 본 발명의 일 실시예에 따른 신축이음장치(100)는 터널 중 곡률을 갖는 아치형상의 상부벽에 적용되는 것을 예로 들어 설명하기로 한다.3 is an installation state diagram of the expansion joint according to an embodiment of the present invention. Here, the expansion joint device 100 according to an embodiment of the present invention will be described with an example that is applied to the arch-shaped upper wall having the curvature of the tunnel.

도 3에 나타나는 바와 같이 본 발명의 일 실시예에 따른 신축이음장치가 구조물(200), 즉 상부벽이 아치형으로 형성된 터널에 시공되어 외부에는 끼움수단(30)이 노출되게 된다.As shown in FIG. 3, the expansion joint according to an embodiment of the present invention is constructed in a structure 200, that is, an upper wall of which is formed in an arcuate tunnel, such that the fitting means 30 is exposed to the outside.

터널(200)은 콘크리트(미도시)와 철근(미도시) 등으로 구성되고, 일정 구간마다 유격되는 틈새인 이음틈새가 형성되어 있다. The tunnel 200 is composed of concrete (not shown), rebar (not shown), and the like, and a gap, which is a gap that is spaced at predetermined intervals, is formed.

그런데, 터널(200)의 상부벽의 곡률은 터널 시공상황 등에 따라 각 터널마다 또는 이음틈새마다 곡률이 다르게 나타날 수 있다.However, the curvature of the upper wall of the tunnel 200 may be different curvature for each tunnel or gap between the tunnel depending on the tunnel construction situation.

따라서, 시공하고자 하는 해당 이음틈새에 본 발명의 일 실시예에 따른 신축이음장치(100)를 맞추고, 해당 이음틈새의 곡률에 맞게 작업자가 신축이음장치(100)를 휘어줌으로써 형태를 잡게 된다.Therefore, to fit the expansion joint device 100 according to an embodiment of the present invention to the corresponding seams to be constructed, the operator bends the expansion joint device 100 according to the curvature of the corresponding seams to be shaped.

이와 같이 작업자가 신축이음장치(100)를 휘어지도록 외력을 가하게 되면, 신축이음장치(100)를 구성하는 신축수단(10)과 끼움수단(30) 및 와이어(20)가 휘어지게 되며, 특히 말단이 상호 떨어져 있는 끼움수단(30)의 끼움부(32)의 경우 휘어짐에 따라 상호 가까워지도록 동작하게 되므로 원활한 휘어짐이 가능하게 되는 것이다.When the operator applies an external force to bend the expansion joint 100, the expansion means 10 and the fitting means 30 and the wire 20 constituting the expansion joint 100 is bent, in particular the end In the case of the fitting portion 32 of the fitting means 30 which are spaced apart from each other, it is possible to bend smoothly because it operates to be close to each other as it is bent.
