Description

교량의 신축이음구조 및 그의 시공방법{EXPANSION JOINT AND IT'S EXECUTION METHOD}Expansion joint structure of bridge and its construction method {EXPANSION JOINT AND IT'S EXECUTION METHOD}

본 발명은 상호 연결되는 교량의 슬라브 간의 이음부 또는 교량의 슬라브와 고정단 간의 이음부를 신축가능하게 연결하는 교량의 신축이음구조 및 그의 시공방법에 관한 것이다.The present invention relates to a flexible joint structure of a bridge and a construction method thereof, which elastically connect a joint between a slab of a bridge or a joint between a slab of a bridge and a fixed end.

일반적으로 교량의 슬라브 간의 이음부마다 일정한 유격을 가지는 신축이음부를 설치하게 된다. 따라서 온도신축에 의한 교량 슬라브의 신축길이를 신축이음부에 효율적으로 흡수하여 주게 된다.In general, each joint between the slabs of the bridge is provided with expansion joints having a certain clearance. Therefore, the expansion and contraction length of the bridge slab by the expansion and contraction of the temperature is effectively absorbed in the expansion joint.

종래의 교량 상판의 신축이음구조는 도 1에서 도시되는 바와 같이, 상호 대향하여 연결되는 슬라브(2)들의 이음부에 각기 타설되며 좌,우 무수축콘크리트(3)들과, 상기 무수축콘크리트(3)들의 상부에 각기 무수축콘크리트(3)에 매설되는 앵커 볼트(5)로 고정되며 도 1의 (b)와 같이 이격되게 설치되는 'ㄱ'자형 핑거형태의 좌,우철판(4)으로 구성된다.As shown in FIG. 1, the conventional expansion joint structure of the bridge deck is placed on the joints of the slabs 2 which are connected to each other, and the left and right non-concrete concretes 3 and the non-concrete concrete ( 3) to the left and right iron plate (4) of the 'b' shaped finger type is fixed to the anchor bolt (5) embedded in the non-concrete concrete (3), respectively, spaced apart as shown in Figure 1 (b) It is composed.

이와 같이 구성되는 종래의 것은 교량 슬라브가 온도에 의하여 신축이 되면 이음부의 이격되게 설치된 'ㄱ'자형 핑거형태의 좌,우철판(4)의 간격이 흡수하게 된다.In the conventional structure configured as described above, when the bridge slab is stretched and contracted by temperature, the gap between the left and right iron plates 4 of the 'a' shaped finger shape spaced apart from the joint is absorbed.

교량 상판의 신축이음구조에 대하여 첨부된 특허문헌 1 내지 3과 같이 다양한 기술들이 제공되어 있으며, 현재에도 계속 개발되고 있는 실정이다.Various technologies are provided as described in Patent Documents 1 to 3 with respect to the expansion joint structure of the bridge deck, which is still being developed.

특허문헌 1 내지 3과 종래에 사용중인 교량 상판의 신축이음구조에는 서로 대향하는 슬라브 단부에 무수축콘크리트를 가진다.The expansion joint structure of the patent document 1-3 and the bridge top plate currently used has non-contraction concrete in the slab edge part which mutually opposes.

이와 같이 슬라브 타설시 함께 타설되지 않고, 별도로 타설되는 무수축콘크리트는 차량의 통행으로 발생하는 반복하중에 자주 파손되는 단점이 있다. 그러므로 무수축콘크리트는 파손에 의하여 잦은 유지보수를 하게 되고, 이로 인하여 유지보수에 대한 비용 및 차량의 흐름을 방해하는 문제점이 있다.As such, the non-concrete concrete, which is not poured together at the time of slab casting, is separately poured, which is frequently damaged by repeated loads generated by the traffic of the vehicle. Therefore, non-concrete concrete is frequently maintained due to breakage, and thus there is a problem of hindering the cost of maintenance and the flow of the vehicle.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서,The present invention is invented to solve the above problems,

차량의 주행으로 발생하는 반복하중에 의하여 자주 파손되는 무수축콘크리트를 포함하지 않는 교량의 신축이음구조 및 이의 시공방법을 제공하고자 한다.It is an object of the present invention to provide a flexible joint structure of a bridge that does not include non-concrete concrete which is frequently damaged by repeated loads generated by driving of a vehicle, and a construction method thereof.

상기 과제를 해결하기 위하여 본 발명의 교량의 신축이음구조는,In order to solve the above problems, the expansion joint structure of the bridge of the present invention,

교량의 신축이음구조에 있어서, 서로 대향하여 연결되는 슬라브들의 이음부 상부에 콘크리트 타설시 일체형태로 'L'자 형태의 받침부재를 각각 설치하고, 상기 받침부재에 일체형태로 탄성 신축이음장치를 설치하여 이루어짐을 특징으로 한다.In the expansion joint structure of the bridge, 'L' shaped support members are installed in the form of concrete when the concrete is placed on the joints of the slabs connected to each other, and the elastic expansion joint device is integrally formed on the support members. Characterized in that the installation.

상기 신축이음장치는 탄성의 성질을 가지는 금속재질로 이루어지며, 상기 신축이음장치는 받침부재와 일체형태로 설치되는 테두리부와, 상기 테두리부에 사이에 이격되게 설치된 다수개의 탄성부재로 구성된다.The expansion joint device is made of a metal material having an elastic property, the expansion joint device is composed of a rim portion which is installed integrally with the support member, and a plurality of elastic members spaced apart between the rim portion.

상기 테두리부의 끝단부는 각각 절곡되어 꺾임부가 형성되며, 상기 꺾임부는 서로 어긋나도록 마주보는 것을 특징으로 한다.End portions of the edges are each bent to form a bent portion, wherein the bent portions are opposed to each other.

상기 탄성부재는 적어도 하나 이상의 절곡부가 형성된 금속판으로 이루어지거나, 또는 호형상으로 절곡된 금속판으로 이루어진다.The elastic member is made of a metal plate formed with at least one bent portion, or made of a metal plate bent in an arc shape.

또 다른 발명인 교량의 신축이음구조의 시공방법은,Another method of construction of the expansion joint structure of the bridge,

(Ⅰ) 서로 대향하여 연결되는 좌,우 슬라브들의 이음부 상부에 이격되게 다수의 앵커를 슬라브 타설시 매립하여 설치하여 받침부재를 설치하고,(Ⅰ) Install the supporting member by installing a plurality of anchors buried at the time of slab laying so as to be spaced apart from the upper part of the joints of the left and right slabs connected to each other.

(Ⅱ) 상기 받침부재에 신축이음장치를 용접하여 일체 형태로 설치함으로써 완료됨을 특징으로 한다.(II) characterized in that completed by welding the expansion joint to the support member is installed in an integral form.

상기와 같이 이루어진 발명은, 슬라브와 별도로 타설되는 무수축콘크리트를 제거함으로써 이로 인한 문제점을 해결할 수 있게 된다.The invention made as described above, it is possible to solve the problems caused by removing the non-contraction concrete that is poured separately from the slab.

즉, 무수축콘크리트 타설로 인한 양생 기간으로 발생하는 공사기간을 단축할 수 있으며, 슬라브와 함께 타설되지 않음으로써 강도가 슬라브에 비하여 취약해질 수 있어 잦은 파손이 발생할 수 있는 것을 방지할 수 있어 잦은 유지보수에 따른 비용 및 통행의 불편한 문제점을 해결할 수 있다.That is, the construction period caused by curing period due to non-concrete concrete casting can be shortened, and since it is not poured together with slabs, the strength can be weaker than that of slabs, so that frequent breakage can be prevented. It can solve the inconvenience of cost and traffic.
