Description

교량 유지관리용 정착부 시공방법{Anchorage establishment method for bridge maintenance and management}Anchorage establishment method for bridge maintenance and management}

본 발명은 교량 유지관리용 정착부 시공방법에 관한 것이다.The present invention relates to a method for constructing a fixing unit for bridge maintenance.

일반적으로 프리스트레스트 철근콘크리트 교량이나 철근콘크리트 교량에 있어, 공용 중 보수 및 보강을 위한 유지관리용 정착부는 주로 거더의 복부 측면에 돌출된 콘크리트 블록을 설치하여 그 콘크리트 블록 내에 설치하고 있다.In general, in prestressed reinforced concrete bridges or reinforced concrete bridges, maintenance fixing units for maintenance and reinforcement during common use are mainly installed in the concrete blocks by protruding concrete blocks protruding on the ventral side of the girder.

이와 같은 유지관리용 정착부는 교량의 유지관리를 위한 효율성은 좋으나, 교량미관을 약화시키는 측면이 있다.Such maintenance fixing unit has good efficiency for maintenance of the bridge, but has a side that weakens the bridge aesthetics.

또한, 상기 유지관리용 정착부는 추후 유지관리를 위한 PS강선 긴장시 별도의 비계구조물 설치나 크레인 등을 동원하여 거더 복부 측면에 설치된 유지관리용 정착부에 접근하여 PS강선을 삽입, 긴장하여야 하는 관계로 작업이 복잡할 뿐만 아니라 까다로운 문제점이 있다.In addition, the maintenance fusing unit should be inserted into the PS steel wire to tension the PS steel wire for future maintenance to approach the maintenance fixing unit installed on the side of the girder by mobilizing a separate scaffolding structure or a crane, etc. Not only is the work complicated, but there are also difficult problems.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로 서, 공용중 빔의 유지관리를 위한 유지관리용 정착부의 PS강선의 긴장작업을 교량 상부슬래브에서 별도의 추가장비 투입없이 유지관리용 정착부에서 PS강선 긴장만으로도 용이하게 긴장할 수 있도록 한 교량 유지관리용 정착부 시공방법을 제공하는데 그 목적이 있다.Thus, the present invention was devised to solve the problems as described above, maintaining the tension work of the PS steel wire of the maintenance fixing unit for the maintenance of the beam in common without maintaining additional additional equipment in the bridge upper slab The purpose of the present invention is to provide a method for constructing a bridge for maintenance of bridges, which makes it easy to tension the steel wire in the management fixing unit.

상기한 목적을 달성하기 위한 본 발명에 따른 교량 유지관리용 정착부 시공방법은 PSC 거더 상부플랜지 양단부 상면에 오목한 형상으로 유지관리용 정착부를 설치하는 단계(Ⅰ); 상기 유지관리용 정착부에 미리 제작된 유지관리용 정착부 충전블록을 삽입 설치하는 단계(Ⅱ); 상기 유지관리용 정착부와 유지관리용 정착부 충전블록과의 사이를 실링재로 도포하는 단계(Ⅲ); 슬래브 철근을 배근하고 콘크리트를 타설하여 슬래브를 형성하는 단계(Ⅳ); 상기 슬래브상에 아스콘을 포장하여 공용하는 단계(Ⅴ)로 이루어짐을 특징으로 한다.Bridge maintenance fixing unit construction method according to the present invention for achieving the above object comprises the steps of installing the maintenance fixing unit in a concave shape on the upper surface of both ends of the upper flange of the PSC girder (I); Inserting and installing the maintenance fixing unit charging block prepared in advance in the maintenance fixing unit (II); Applying a sealing material between the maintenance fixing unit and the maintenance fixing unit filling block (III); Reinforcing the slab reinforcing bars and pouring concrete to form a slab (IV); It is characterized by consisting of the step (V) to share the ascon on the slab.

이상에서 설명한 바와 같이, 본 발명에 따른 교량 유지관리용 정착부 시공방법은 다음과 같은 효과가 있다.As described above, the construction method for fixing the bridge maintenance according to the present invention has the following effects.

첫째, 본 발명은 유지관리용 정착부를 교량 상면에 설치함으로써, 추후 공용 중 유지관리시 별도의 가시설 설치나 중장비의 동원없이 교량 상면의 유지관리용 정착부에서 PS강선을 삽입 설치하여 긴장하므로 시공을 용이하게 할 수 있는 이점이 있다.First, the present invention by installing the maintenance fixing unit on the upper surface of the bridge, the installation of the PS steel wire in the maintenance fixing unit of the upper surface of the bridge without the installation of additional temporary facilities or mobilization of heavy equipment during the maintenance of the common use, so that the construction There is an advantage that can be facilitated.

둘째, 본 발명은 기존과 같이 교량의 측면에 별도의 정착블록을 설치하지 않 으므로 교량의 미관도 증대되는 이점이 있다.Second, since the present invention does not install a separate fixing block on the side of the bridge as conventional, there is an advantage that the aesthetics of the bridge is also increased.

셋째, 본 발명은 유지관리용 정착부 충전을 콘크리트블록으로 하므로 추후 유지관리시 현장타설 콘크리트 등으로 충전하였을 경우 충전부를 절삭기로 철거하여야 하는 시공과정을 생략할 수 있어 간단하게 유지보수를 할 수 있고, 유지관리용 정착부 충전블록을 손상없이 재사용이 가능하므로 저비용으로 유지보수를 수행할 수 있는 장점이 있다. Third, the present invention, because the filling of the maintenance fixing unit to the concrete block, when the maintenance in the future, when the filling of the cast concrete, such as the construction process to remove the filling unit with a cutting machine can be omitted simply to maintain In addition, there is an advantage that the maintenance can be performed at low cost because it can be reused without damage to the fixing unit charging block for maintenance.

(12) The maintenance fixing unit 14 is formed in a concave shape on the upper surface of both ends, and the maintenance fixing unit 14 is inserted into the maintenance fixing unit charging block 16, which is manufactured in advance, for maintenance. After filling the fixing unit 14 and forming the slab 20 and the ascon 22, and during maintenance during the common use, the paved slab 20 and the ascon 22 are cut by a cutting machine and removed, After the maintenance fixing unit charging block 16 is withdrawn from the management fixing unit 14, the sheath 36 and the concrete molded steel fixing unit insert 38, which are already installed in the maintenance fixing unit 14, are removed. The PS steel wire 24 and the steel fixing hole 26 are inserted and installed to keep the PS steel wire 24 pulled out again. By inserting a fixing portion Lyon charge block 16 to maintain the fixing section (14) it is characterized in that the filling being maintained fixing section (14).

따라서, 상기한 바와 같은 본 발명에 따른 교량 유지관리용 정착부 시공방법은 유지관리용 정착부(14)를 교량의 상면에 설치하므로 추후 공용 중 유지관리시 별도의 가시설 설치나 중장비의 동원없이 교량의 상면에서 PS강선(24)을 삽입 설치하여 긴장하므로 시공을 용이하게 할 수 있고, 별도의 측면 정착블록을 설치하지 않으므로 교량의 미관도 증대되고, 유지관리용 정착부 충전블록(16)을 재사용할 수 있으므로 저비용으로 유지보수를 수행할 수 있는 작용효과가 있다.Therefore, the method for constructing the bridge maintenance fixing unit according to the present invention as described above is to install the maintenance fixing unit 14 on the upper surface of the bridge, so that the bridge without additional installation or mobilization of heavy equipment during maintenance in the future PS steel wire 24 is inserted into the upper surface of the tension to facilitate the construction, and because a separate side fixing block is not installed, the aesthetics of the bridge is increased, and the maintenance fixing unit charging block 16 is reused. As a result, maintenance can be performed at low cost.
