본 발명은 고강도 강판과 볼트를 이용하여 제작한 H형 압연강재에 프리스트레스를 도입한 H형 압연강재보 제작방법과 이를 이용한 교량시공방법에 관한 것으로서, 기존의 H형 압연강재에 일정량 솟음을 주고 H형 압연강재에 수직보강재를 일정길이마다 설치하며 H형 압연강재의 양측단부에 일정길이의 가부재를 설치한 정, 부모멘트부재의 H형 압연강재 4개를 1개조로 하여 작업대에 설치한 후에 양쪽단부에서 지간의 L/4지점에 H형 압연강재사이에 각각 유압잭을 설치하고 H형 압연강재의 양측단부의 가부재끼리 반력대로 서로 연결하고 타측에 인접한 H형 압연강재를 크로스 빔으로 연결한 후에 서서히 유압잭에 설계된 프리스트레스 하중을 가한 후에 H형 압연강재의 정모멘트 부재의 하부 및 부모멘트 부재의 상하부에 설치된 고강도 강판을 완전히 용접 또는 볼트 조립하여 H형 압연강재와 일체화를 시킨 후에 유압잭에 가한 프리스트레스 하중을 제거하면 프리스트레스가 도입된 H형 압연 강재보가 제작된다. 상기 제작된 H형 압연 강재보의 정모멘트 부재는 교량 지간의 3/4길이로 제작하고 부모멘트 부재는 교량지간의 2/4길이로 제작하고 플랜지 상부는 상기 H형 압연 강재보 제작시 설치된 고강도 강판에 의해 단차가 발생되므로 이들 사이에 채움판을 설치하여 단차를 없애고 난 후에 중앙에 부모멘트 부재를 양측에는 정모멘트 부재를 설치한 후에 정,부모멘트 부재를 서로 볼트로 연결하고 난 후에 교대위에 설치하면 교량의 빔이 가설된다.The present invention relates to a method of manufacturing H-shaped rolled steel beams in which pre-stress is introduced into H-rolled steel fabricated by using high-strength steel plate and bolts, and a bridge construction method using the same. The vertical reinforcement is installed on the rolled steel at certain lengths and the temporary members with fixed lengths are installed at both ends of the H-rolled steel. Hydraulic jacks are installed between the H-shaped rolled steel at L / 4 points between the ends at both ends, and the members at both ends of the H-shaped rolled steel are connected to each other by reaction force, and the H-rolled steel adjacent to the other side is connected by cross beams. Later, after gradually applying the prestress load designed to the hydraulic jack, the high strength steel plate installed in the lower part of the static moment member of the H-rolled steel and the upper and lower parts of the parent moment member was completely melted. H-rolled steel beams with prestresses are produced by removing the pre-stress loads applied to the hydraulic jacks after integrating the H-rolled steels by contact or bolt assembly. The positive moment member of the manufactured H-shaped steel beams is made of 3/4 length between bridge sections, and the parent-moment member is made of 2/4 length between bridge sections. Steps are generated by the steel plate, so the filling plate is installed between them to eliminate the step, and then the parent moment member is installed at the center and the positive moment member is installed at both sides, and then the positive and minor moment members are bolted to each other. When installed, the beams of the bridge are installed.

본 발명은 기존의 H형 압연압연 강재는 제품의 생산 규격이 작아 교량등과 같은 토목구조물에 적용하는데 많은 제한을 받고 있다. 현재의 강재를 이용한 교량의 설치시에는 판형강재를 절단용접하여 각 교량의 길이에 맞도록 절단한 후에 용접제작하여 교량에 가설되고 있어 많은 제작비용과 공사기간이 길어지는 문제점이 있어 이를 해결하기 위하여 기성제품인 H형 압연강재에 프리스트레스를 도입한 H형 압연 강재보의 정,부모멘트 부재를 서로 연결하여 교량을 위한 빔으로 제작하여 교량을 설치하면 규격화된 H형 압연강재보를 장지간화하여 중소규모의 교량에 적용하므로서 판형강재를 이용할때보다 제작비용의 절감과 공사기간의 단축에 기여할 수 있는 공법을 제공하는데 목적이 있다.The present invention is a conventional H-rolled rolled steel is a product of the production standard is small and is limited to apply to civil structures such as bridges. In the installation of bridges using current steel, plate-shaped steel is cut and welded, cut to fit the length of each bridge, welded and installed on the bridges. When the bridges are installed by connecting the positive and minor moment members of H-rolled steel beams with pre-stressed H-rolled steel beams, which are pre-stressed products, to be installed as beams for bridges, the standardized H-rolled steel beams are long-term The purpose is to provide a construction method that can contribute to reduction of manufacturing cost and construction period than when using plate steel.

일반적으로 교량의 가설에는 판형강재를 교량의 길이에 따라 절단하여 교량의 빔을 제작하여 교량건설에 사용하여 왔으나 판재를 재단 및 용접하여 교량의 빔을 제작하는 제작기간과 이를 운반하여 설치하는 설치비용이 많이 소요되어 비경제적인 공사방법으로 인식되어 왔고, 또한 기성제품인 H형 압연강재를 사용할 경우에도 압연강재의 최대크기는 높이가 808mm이고 폭이 302mm에 불과하여 교량에 바로 사용하기에는 강성이 모자라 많은 어려움이 따른다. 이러한 한계로 인하여 보조용 가설구조물에 주로 사용되고 있는 실정이다. 최근 이러한 한계를 극복하기 위한 방법으로 도 1과 같이 H형 압연강재(10)의 외부에 강봉(12) 또는 강연선(11)의 텐던을 지지대(13)를 이용하여 직선 혹은 곡선배치하고 텐던에 긴장력을 도입하여 우력모멘트에 의한 내하력을 증가시켜 압연강재의 강성을 보완하여 교량에 사용하고 있다. 그러나 이러한 방법은 우력모멘트에 의한 압연강재의 내하력은 증가하지만 보 자체의 근본적인 강성보강이 이루어지지않아 처짐 및 진동의 사용성 한계 때문에 교량의 장지간화가 어렵고, 텐던이 외부에 노출되어 있어 외력에 의한 파손 및 이에따른 프리스트레스의 손실우려가 있으며 외관이 미려하지 못한 문제점이 있다.In general, in the construction of bridges, plate steels are cut along the length of bridges to produce beams of bridges and used for bridge construction.However, the production period for the production of beams of bridges by cutting and welding plate materials and the installation cost for carrying them It has been recognized as a cost-effective construction method, and even when using the H-shaped rolled steel, which is a ready-made product, the maximum size of the rolled steel is 808mm in height and 302mm in width. This follows. Due to these limitations, the situation is mainly used for auxiliary construction structures. Recently, as a method for overcoming these limitations, the tendons of the steel rods 12 or the strands 11 or 11 are linearly or curvedly arranged using the support 13 to the outside of the H-shaped rolled steel 10 as shown in FIG. By increasing the load capacity due to the moment of inertia, the rigidity of the rolled steel is supplemented and used in bridges. However, in this method, the load capacity of the rolled steel increases due to the moment of moment, but the fundamental rigidity reinforcement of the beam itself is not achieved. And there is a concern about the loss of prestress accordingly and there is a problem that the appearance is not beautiful.

Complement the rigidity of the product and install each of the positive and second moment members and install them as beams of bridges.The production method is simpler and cheaper to install than conventional plate steels. The purpose is to provide a suitable installation method.
