Description

방수 및 차수기능을 향상시킨 방음벽 구조체{SOUNDPR00F WALL STRUCTURE}Soundproof wall structure with improved water resistance and degree of function {SOUNDPR00F WALL STRUCTURE}

본 발명은 방수 및 차수기능을 향상시킨 방음벽 구조체에 관한 것으로, 특히 상판과 방음벽 세그먼트의 결합구조가 조립식으로 간편하게 시공되어 일체화되도록 조립함과 아울러, 방수성을 향상시킬 수 있도록 그 구조가 개선된 방수 및 차수기능을 향상시킨 방음벽 구조체에 관한 것이다.The present invention relates to a soundproof wall structure having improved waterproofing and ordering function, and in particular, the combined structure of the upper plate and the soundproofing wall segment can be easily assembled and integrated to be assembled, and the structure is improved to improve the waterproofness. The present invention relates to a soundproof wall structure having improved order function.

일반적으로, 교량 공사에서 시공되는 교각은 현장 타설 콘크리트구조로서, 현장에서 기초터파기 작업후에 기초 철근 및 거푸집을 설치한 상태에서 콘크리트를 타설하고, 그 콘크리트의 타설후에 일정 시간동안 양생과정을 거쳐 기초부를 형성하게 된다.In general, the bridge piers constructed in bridge construction are cast-in-place concrete structures, where concrete is laid with foundation reinforcing bars and formwork after foundation excavation at the site, and after the concrete is laid To form wealth.

이어서, 양생된 기초부의 상측으로 철근과 거푸집을 형성해 가면서 교각 기둥을 양생하고, 교각 기둥의 상부 즉, 교량의 상판을 받치는 상측 부분은 동바리를 받쳐 놓고, 거푸집을 배치한 상태에서 1차 또는 2차 공정으로 콘크리트 타설하여 상측부를 형성시키는 공법으로 교각을 완성하게 된다.Subsequently, the bridge column is cured while forming reinforcing bars and formwork on the upper side of the cured foundation, and the upper part of the bridge column, that is, the upper part supporting the upper plate of the bridge, supports the copper bar, and the primary or secondary The pier is completed by the method of forming concrete by placing concrete in the process.

이로 인해, 거푸집의 설치와 시공 이음 및 시공후 거푸집의 탈형 작업등에서 공사기간이 길어지게 됨과 아울러 공사 비용이 상승되는 요인으로 작용하게 된다.As a result, the construction period is prolonged and the cost of the construction is increased in the installation of the formwork, the jointing of the formwork, and the demolding of the formwork after the construction.

또한, 교각은 시공되는 위치에 따라 고가 도로 건설의 경우에는 공사가 시공되는 현장 주변에 교통 혼잡을 줄 수 있으며, 수중공사 등과 같은 열악한 환경에서 작업이 주로 이루어지게 되므로 배수 처리가 양호하지 않을 경우 시공관리가 어렵고 부실시공의 원인이 될 수 있다.In addition, depending on the location of the pier, in the case of overpass road construction, the pier may cause traffic congestion around the site where the construction is being constructed, and if the drainage treatment is not good since the work is mainly performed in a poor environment such as underwater construction, etc. It is difficult to manage and can be the cause of unpaid construction.

이러한 문제점을 개선하기 위해 최근에는 조립식 공법에 의해 교량이 시공되고 있으며, 이는 하부 구조 및 상부 구조가 프리캐스트 타입으로 일정한 장소에서 각기 다수개의 세그먼트(단위 구조물)로 분절되어 제작된 후에, 각각의 세그멘트를 조립하는 공법이다.In order to solve this problem, bridges have been recently constructed by a prefabricated method, which is a precast type which is segmented into a plurality of segments (unit structures) in a predetermined place, and then each segment is manufactured. It is a method of assembling.

이 공법은 콘크리트의 품질 관리가 유리하고, 세그먼트를 연속적으로 제작하므로 인력관리 및 거푸집 전용에 유리하며, 세그먼트 제작을 하부 공사와 병행해서 실시할 수 있으므로 현장 타설방식에 비해서 공기를 단축시킬 수 있는 이점이 있다.This method is advantageous for quality control of concrete, and it is advantageous for manpower management and formwork because it continuously manufactures segments, and it can shorten the air compared to on-site pouring method because segment production can be performed in parallel with subconstruction work. There is this.

그 조립식 공법의 시공방법은, 현장에서 바닥으로부터 기초 터파기를 포함하는 기초 콘크리트 시공을 수행한 후에, 다수개의 세그먼트로 제작된 하부구조 및 상부구조를 크레인을 이용하여 순차적으로 들어올려 조립하는 방식으로 교량을 시공하는 것이다.The construction method of the prefabricated method is, after performing the foundation concrete construction including the foundation trench from the floor in the field, bridges by lifting up and assembling the substructure and superstructure made of a plurality of segments sequentially using a crane It is to construct.

그 거더와 상판 사이에는 통상적으로 판형의 전단연결재가 다수개 설치되고, 그 다수개의 전단연결재에 의해 거더와 상판이 일체화된다.A plurality of plate-shaped shear connectors are usually provided between the girder and the upper plate, and the girder and the upper plate are integrated by the plurality of shear connectors.

여기서, 그 전단연결재들은 그 높이가 상판과 거더의 틈새 간격에 의해 결정되며, 그 틈새 사이의 공간을 메우게 되므로, 틈새의 높이 편차가 각각 발생하게 됨에 따라 차등적인 높이를 갖게 된다.Here, the shear connectors are determined by the gap between the top plate and the girder, and fill the space between the gaps, and thus have a differential height as the gap height occurs.

그 이유는 다수개의 세그먼트가 조립식으로 결합된 거더가 교각상의 코핑부와 코핑부 사이에 설치될 경우, 다수개의 거더는 상호 수평으로 설치되고, 그 수평으로 설치된 거더들 위에 상판이 안착되는 데, 상호 수평으로 설치되어야 할 거더들은 해당되는 거더의 변형 및 제작시의 오차로 인해 정확하게 수평이 되지 않고 국부적으로 곡면이 형성될 수 있다.  The reason is that when a girder having a plurality of segments prefabricated is installed between the pier coping portion and the coping portion, the plurality of girders are installed horizontally with each other, and the top plate is seated on the horizontally installed girders. The girders to be installed horizontally may be locally curved instead of precisely horizontal due to deformation and manufacturing errors of the corresponding girders.

이러한 곡면이 형성되는 변위를 보정하기 위해 전단 연결재를 이용하고 있으며, 그 전단 연결재를 이용한 보정작업시 작업자가 육안으로 거더와 상판과의 간극을 측정한 후에 그 길이가 적합한 전단연결재를 중간에 개재되도록 설치함에 따라, 부정확하게 맞춰질 수 있을 뿐만 아니라, 작업시간이 많이 소요되는 문제점이 있었다.Shear connector is used to compensate for the displacement of the curved surface, and the operator should measure the gap between the girder and the top plate visually and then interpose a shear connector suitable for its length in the calibration operation using the shear connector. According to the installation, not only can be incorrectly matched, there was a problem that takes a lot of work time.

또한, 기존 상판과 거더의 결합구조에서는 빗물의 유입을 차단할 수 있는 방수 및 차수 기능이 마련되어 있지 않으므로, 빗물이 상판의 하부로 유입되어 상판과 거더의 결합수단을 부식시켜 그 결합부위의 내구성을 저하시키거나, 심하게는 교량 붕괴의 요인으로 작용할 우려가 있었다.In addition, in the existing coupling structure of the upper plate and the girder, since the waterproof and the order function to block the inflow of rainwater is not provided, rainwater flows into the lower portion of the upper plate and corrodes the coupling means of the upper plate and the girder, thereby deteriorating durability of the coupling portion. Or severely acting as a factor of bridge collapse.

본 발명은 상기한 제반 문제점을 감안하여 이를 해결하고자 제안된 것으로, 그 목적은 상판과 방음벽간의 조립구조를 단순구조로 간편하게 조립할 수 있도록 함과 아울러, 상판과 상판의 연결부위 및 상판과 방음벽간의 방수성을 향상시킬 수 있도록 한 방수 및 차수기능을 향상시킨 방음벽 구조체를 제공하는 데 있다.The present invention has been proposed to solve the above problems in view of the above problems, the purpose of which is to easily assemble the assembly structure between the top plate and the soundproof wall with a simple structure, and the waterproofing between the top plate and the top plate and the top plate and the soundproof wall The present invention provides a soundproof wall structure with improved waterproof and degree of order.
