본 발명은 교좌구조물의 무수축몰탈 완전충진구조에 관한 것으로서, 더욱 상세하게는 교좌구조물 즉, 교량의 하부 구조물인 교각과 상부 구조물인 상판 사이에 설치되는 베어링, 상부 및 하부판 등 상호간의 구조물들을 접착하는 무수축몰탈의 충진과정에서 빠져나가는 공기를 완전히 제거하여 상기 상판으로부터 전달되는 여러 요인의 연직하중 및 지진에 의한 횡파의 압력이 교각으로 골고루 전달되도록 하는 교좌구조물의 무수축몰탈 완전충진구조에 관한 것이다. The present invention relates to a complete non-shrink mortar filled structure of the bridge structure, and more specifically, to bond the structure between the structure, that is, the bearings, upper and lower plates installed between the bridge and the upper plate of the upper structure of the bridge structure In the complete filling structure of the non-condensation mortar of the bridge structure to completely remove the air escaped during the filling process of the non-condensation mortar so that the vertical load and the pressure of the transverse wave caused by the earthquake are transmitted evenly to the piers. will be.

일반적으로 교좌장치는 교각과 다리 상판 사이에 설치되어 상부 하중 전달 및 온도 변화 등에 따른 신축작용을 원활하게 하여 교량의 안전을 도모하는데 있고, 교좌장치의 종류도 다양하게 착안되어 있다. In general, the bridge device is installed between the bridge and the bridge top plate to facilitate the expansion and contraction action according to the upper load transfer and temperature change, etc. to promote the safety of the bridge, the type of bridge device is also variously conceived.

상기한 교좌장치는 스터드볼트에 의해 매입 설치되는 하부판과, 교량 상판으로 설치되는 상부판 사이에 베어링이 개재되는 것이 있고, 상부판과 하부판 사이에 탄성받침이 개재된 것이 있다. In the above-described stabilization device, a bearing is interposed between a lower plate embedded by a stud bolt and an upper plate installed as a bridge upper plate, and an elastic support is interposed between the upper plate and the lower plate.

상기 교좌장치 중 교량에서 발생하는 신축, 회전 등의 교축방향 변형을 흡수해주는 베어링을 갖는 교좌장치는 3가지 타입으로서 양방향 가동타입과 일방향 가동타입 및 양방향 고정타입으로 나누어진다. Among the chair apparatuses, the chair apparatus having a bearing for absorbing the deformation in the axial direction such as stretching and rotation occurring in the bridge is divided into three types, a two-way movable type, a one-way movable type and a bidirectional fixed type.

상기와 같이 이루어진 베어링을 갖는 교좌장치는 신규설치 및 무수축 몰탈을 하부판의 측면에서 공급 타설할 때 공기가 빠져나가지 못해 하부판과 교각 상면 사이에 공극이 발생되게 되는 문제점이 있다. The bridge device having a bearing made as described above has a problem in that air is not released when new installation and non-shrink mortar is poured from the side of the bottom plate so that a gap is generated between the bottom plate and the top of the pier.

이러한 공극이 발생할 경우 하부판이 쉽게 휘어지게 되고, 공명현상이 발생하여 무수축몰탈과 함께 교각에 균열이 발생하는 치명적인 단점이 초래된다. When such voids occur, the lower plate is easily bent, and resonance occurs, resulting in a fatal disadvantage of cracking in the piers together with mortar.

부가하여, 교량의 노후화 및 차량의 이동 하중에 의해 하부판이 부식 또는 변형(휘어짐)이 일어나거나 무수축몰탈의 심각한 균열이 발생하게 되면 상판을 인상시킨 후 변형이 일어난 하부판을 교각에서 분리한 다음 교체할 하부판을 안착시키는 유지보수를 하게 되는데, 이 때에도 역시 공극이 발생하기 때문에 제대로 된 보수공사가 실현되지 않는 단점이 있다. In addition, if the lower plate is corroded or deformed due to the aging of the bridge and the moving load of the vehicle, or if severe cracking of the shrinkage mortar occurs, the upper plate is raised and then the deformed lower plate is removed from the bridge and then replaced. There is a maintenance to seat the lower plate to be, this time also there is a gap occurs because there is a disadvantage that the proper repair work is not realized.

따라서, 본 발명은 상기 제반문제를 해결하기 위해 창출된 것으로서, 그 목적은, 교좌구조물 즉, 교량의 하부 구조물인 교각과 상부 구조물인 상판 사이에 설치되는 베어링, 상부 및 하부판 등 상호간의 구조물들을 접착하는 무수축몰탈의 충진과정에서 빠져나가는 공기를 완전히 제거하여 상기 상판으로부터 전달되는 여러 요인의 연직하중 및 지진에 의한 횡파의 압력이 교각으로 골고루 전달되도록 하는 교좌구조물의 무수축몰탈 완전충진구조를 제공함에 있다. Accordingly, the present invention has been made to solve the above problems, the object of which is to bond the structures of the bridge structure, that is, the bearings, upper and lower plates installed between the bridge and the upper plate of the upper structure of the bridge structure To completely remove the air escaped during the filling process of the non-shrink mortar provides a complete filling structure of the non-shrink mortar of the bridge structure to ensure that the vertical load and the pressure of the transverse wave caused by the earthquake are transmitted evenly to the piers. Is in.

In the bridge structure of the bridge composed of the non-shrink mortar 26, the air remaining in the space portion of the non-shrink mortar 26 is completely removed to remove the load applied from the bridge structure and the top plate. (10) to evenly distribute to ensure the durability of the entire bridge.

구체적으로, 도 1 및 도 2에 도시된 바와 같이, 본 구성의 일 실시예는 상기 하부판(24)의 하부에 하부보강판(24-1)을 덧댄 경우에 상기 하부보강판(24-1) 상에 무수축몰탈(26)이 충진되는 공간부와 연통하는 공기배출구(30)를 형성하여, 몰탈의 타설시 잔존해 있던 공기가 하부판(24)과 하부보강판(24-1) 사이의 틈새를 통해 외기로 배출되도록 한 구성이다. 이러한 공기배출구(30)의 형태는 도 5a 및 도 5b와 같다. Specifically, as shown in FIGS. 1 and 2, one embodiment of the present configuration is the lower reinforcing plate 24-1 when the lower reinforcing plate 24-1 is padded under the lower plate 24. An air outlet port 30 is formed in communication with the space portion in which the non-contraction mortar 26 is filled, so that the air remaining during the pouring of the mortar is formed between the lower plate 24 and the lower reinforcing plate 24-1. It is configured to be discharged to the outside air through. The shape of the air outlet 30 is the same as that of FIGS. 5A and 5B.

한편, 도 3 및 도 4에 도시된 바와 같이, 본 구성의 다른 실시예는 상기 하부판(24)의 하부에 하부보강판(24-1)을 덧댄 경우에 상기 하부보강판(24-1) 상에 무수축몰탈(26)이 충진되는 공간부와 연통하는 공기배출구(30)와, 그 공기배출구(30)로부터 빠져나가는 공기를 외기까지 직접 안내하도록 연장 형성된 공기배출홈(32)의 구성이다. 이러한 공기배출구(30) 및 공기배출홈(32)의 형태는 도 6a 내지 도 6f와 같이 매우 다양하게 실시할 수 있다. On the other hand, as shown in Figures 3 and 4, another embodiment of the present configuration in the case of the lower reinforcing plate 24-1 to the lower portion of the lower plate 24, the upper reinforcing plate 24-1 The air outlet port 30 communicates with the space portion in which the non-shrink mortar 26 is filled, and the air outlet groove 32 extended to directly guide the air exiting from the air outlet port 30 to the outside air. The air outlet 30 and the air outlet groove 32 may be implemented in various ways as shown in FIGS. 6A to 6F.

상기와 같이 구성된 본 발명의 작동상태를 설명하면 다음과 같다. Referring to the operating state of the present invention configured as described above are as follows.

상부판(21), 베어링(25), 하부판(24)(24-1)으로 구성된 교좌구조물(20)을 교각구조물(10) 상부에 올려 놓고 교좌구조물의 측방으로 무수축몰탈(26)을 충진하여 타설한다. The bridge structure 20 composed of the upper plate 21, the bearing 25, and the lower plate 24, 24-1 is placed on the upper portion of the bridge structure 10, and the non-contraction mortar 26 is filled to the side of the bridge structure. Pour it out.

참고로 무수축몰탈(26)은 조기강도가 높아 긴급 보수재로서의 성능과 접착력이 매우 뛰어나다.For reference, the non-shrink mortar 26 has high early strength and excellent performance and adhesion as an emergency repair material.

상기 무수축몰탈(26)의 충진은 그 구조물상에 잔존해 있던 공기가 밀려져 배출됨을 의미하고, 그 공기는 본 발명의 일실시예와 같이 하부 보강판(24-1)에 형성된 공기배출구(30)를 통해 하부판(24)과 하부 보강판(24-1) 사이의 틈새를 통해 배출되거나, 다른 실시예와 같이 하부 보강판(24-1)에 형성된 공기배출구(30)를 통해 그 공기배출구(30)와 연장 형성된 공기배출홈(32)을 거쳐 외기로 배출되도록 함으로써 공극을 완전히 없애 완전한 충진이 이루어지도록 하는 것이다. The filling of the non-shrink mortar 26 means that the air remaining on the structure is pushed out and discharged, the air is formed in the air outlet port formed in the lower reinforcing plate (24-1) as in one embodiment of the present invention ( 30 is discharged through the gap between the lower plate 24 and the lower reinforcing plate 24-1, or through the air outlet 30 formed in the lower reinforcing plate 24-1 as in other embodiments The air is discharged to the outside through the air discharge groove 32, which extends through the 30, to completely fill the voids to completely fill the air.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변경 및 변경이 가능하다는 것이 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, changes, and modifications are possible in the technical field of the present invention without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

이상에서와 같은 본 발명을 적용하게 되면, 앞서 설명한 바와 같이 무수축몰탈의 충진 타설시 공기배출구 및 공기배출홈을 통해 구조물 내부에 잔존해 있던 공극을 완전히 배출시키고 완전충진이 가능하기 때문에 구조물 서로간의 밀착력을 높여 교량의 내구성을 극대화시킬 수 있고, 뿐만 아니라 이러한 확고한 내구성 확보는 교량의 보수공사시에도 계속적으로 이어지기 때문에 무엇보다 교량의 안정성에 크게 기여할 수 있다. When the present invention is applied as described above, the filling of the non-shrink mortar as described above through the air outlet and the air outlet groove completely discharges the remaining voids inside the structure and can be completely filled with each other It is possible to maximize the durability of the bridge by increasing the adhesion, as well as to ensure the durability of this bridge can be greatly contributed to the stability of the bridge, because it continues during the repair work of the bridge.
