Abstract

A precast concrete structure and a construction method of a bridge slab using the precast concrete structure are provided to prevent environmental pollution and accidents in a construction site and to reduce a period of construction by manufacturing standardized precast concrete structures in a factory, putting on a steel-frame beam using a crane and arranging reinforcing bars, and then placing concrete. A precast concrete structure(10) for a bridge slab comprises: a reinforcement unit(11) formed to have the same width(W) as the width of a bridge and the length(L) of 2~3 meters by arranging upper and lower reinforcing bars(11a) in two or more rows along the widthwise direction of a bridge and connecting in the mountain shape using short reinforcing bars(11b); and an L-shaped railing(12) formed by placing concrete to make the lower reinforcing bars of the reinforcement unit on both ends of the reinforcement unit in the same width as the width of a bridge. A construction method of a bridge slab using the precast concrete structure comprises the steps of: fixing a packing such as silicon on both edges of a steel-frame beam installed on the upper part of a bridge bearing plate and forming an assembly key on the inside of the packing to be projected longitudinally; arranging precast concrete structures continuously by lifting up precast concrete structures using a crane and placing on the upper part of the steel-frame beam to make the bottom of the railing adhered closely to the assembly key; arranging reinforcing bars on the reinforcement unit of the precast concrete structure longitudinally and welding to the steel-frame beam using stud bolts; and placing concrete to make the reinforcement unit buried.

본 발명은 교량 상판용 피씨(PC; Precast Concrete(미리 성형된 콘크리트))구조체 및 교량 상판용 PC구조체를 이용한 교량 상판의 시공방법에 관한 것으로서, 보다 구체적으로는 교각 위에 설치되어 있는 철골빔 상측으로 설치되는 상판을 규격화된 구조체로 구성하고 이를 현장에서 철골빔에 안치한 후 별도의 거푸집 잡업 없이 콘크리트 타설이 이루어질 수 있게 함으로 해서 신속한 공사 진행, 안전성 확보가 이루어질 수 있게 한 것이다.The present invention relates to a method for constructing a bridge deck using a PC (Precast Concrete (preformed concrete)) structure and a bridge deck PC structure, and more specifically, to an upper side of a steel beam installed on a bridge. The installed top plate is composed of a standardized structure and placed in a steel beam at the site, so that concrete pouring can be performed without additional formwork, thereby enabling rapid construction progress and securing safety.

다리는 교각 상측에 설치되어 있는 교량받침판과 이웃하는 교량받침판 상부에 철골빔을 안치하고, 그 상측으로 콘크리트 구조의 상판을 시공하게 된다.The bridge lays a steel beam on the bridge support plate installed above the bridge and the adjacent bridge support plate, and constructs the concrete plate on the upper side thereof.

상기한 상판의 일반적인 설치는 철골빔 혹은 교각 등에 고정되어 있는 비계 상측에 거푸집을 만들고 거푸집 상측에 철근을 배열한 상태에서 콘크리트를 타설하여 슬래브를 형성하고 이 슬래브의 가장자리에 다시 거푸집 및 철근 배근작업을 행한 후 콘크리트 타설하여 난간대를 슬래브와 일체가 되게 형성하여 상판을 완성하게 된다.The general installation of the upper plate is to form a slab on the upper side of the scaffold fixed to the steel beams or piers, and to lay the slab by arranging the reinforcing bar on the upper side of the formwork to form a slab and rework the formwork and reinforcement on the edge of the slab again. After the concrete is poured, handrails are formed integrally with the slab to complete the top plate.

상기한 방법으로 다리의 상판을 시공할 경우 비계 부재 및 거푸집 부재 등을 작업현장으로 운반 보관해야 하며, 고소에서 이들의 설치 작업이 진행되므로 추락의 위험성 등 산업재해발생 빈도가 높았다.When constructing the upper plate of the bridge by the above method, the scaffolding member and the formwork member should be transported and stored at the work site, and their installation work is carried out at the high place, so the frequency of industrial accidents such as the risk of falling was high.

그리고 콘크리트 타설 외에도 비계 및 거푸집 설치 작업 및 이들을 철거하는 작업을 행해야 함으로 현장에서의 작업기간이 길어지는 등의 문제점이 있었다.In addition to the concrete pouring, there was a problem such as a long work period in the field because the work to install the scaffolding and formwork and to remove them.

또한 현장 주변에 많은 자재를 운반 야적하여 사용해야 하는 불편이 있고, 그로 인해 환경문제도 발생하는 등의 여러 문제가 있어 업계에서는 이를 해결할 수 있는 교각의 설치방법이 요구되고 있었다.In addition, there are inconveniences in that many materials must be transported and used around the site, and as a result, there are various problems such as environmental problems. Therefore, there was a demand for a method of installing piers to solve this problem.

이에 본 발명자는 교량의 상판 설치에 따른 상기한 종래 문제점을 일소코자 본 발명을 연구 개발한 것이다.Accordingly, the present inventors have studied the present invention to solve the above-mentioned problems caused by the installation of the upper plate of the bridge.

즉, 본 발명에서는 상판을 PC화하고 이를 현장에서 배열하여 비계 및 거푸집 설치 작업 없이 철근을 배근한 후 콘크리트 타설이 이루어질 수 있게 함으로 해서 작업장 주변 환경오손의 염려를 일소하면서도 공기를 대폭 단축할 수 있는 교량 상판용 PC구조체 및 교량 상판용 PC구조체를 이용한 교량 상판의 시공방법을 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.In other words, in the present invention, the top plate is made into a PC and arranged in the field so that the concrete can be placed after reinforcing the reinforcing bars without scaffolding and formwork installation work, which can greatly reduce air while reducing concerns about environmental pollution around the workplace. The present invention has been completed in view of the technical problem of the present invention by providing a construction method of a bridge deck using a PC structure for bridge deck and a PC structure for bridge deck.
