Description

조립식 교각 및 이에 대한 시공방법{Fabricated pier and Fabricated pier construction method}Fabricated pier and fabricated pier construction method

본 발명은 교량을 구성하는 교각을 조립식으로 구축토록 하는 조립식 교각 및 이에 대한 시공방법에 관한 것이다.The present invention relates to a prefabricated piers and a construction method thereof for prefabricating the piers constituting the bridge.

종래 교량 공사에 사용되는 교각의 구축방법으로는 교각의 토대가 되는 기초를 구축한 다음 그 위에 수직 및 수평 철근 배근을 하고, 배근된 철근 주위에 교각 및 교대의 형틀(거푸집)을 조립 설치한 다음, 형틀 안에 콘크리트를 부어 콘크리트가 굳은 후 형틀을 제거하는 과정을 통해 교각을 구축하게 된다.As a method of construction of bridges used in conventional bridge construction, the foundation that is the foundation of the bridges is constructed, vertical and horizontal reinforcement is laid on the bridges, and the pier and the formwork of the bridges are assembled around the reinforcement bars. The bridge is built by pouring concrete into the mold and removing the mold after the concrete is hardened.

이와 같은 교각 구축방법을 현장 타설 교각 구축방법이라고 통칭하게 된다.Such a bridge construction method will be referred to collectively as a site casting bridge construction method.

현장 타설 교각 구축공법은 기초 위에 철근 배근 작업과정, 형틀조립 작업과정 및 특히 콘크리트 경화기간에 따른 기일이 과다하게 소요되어 전체 교각의 구축에 많은 기일이 소요되어지게 된다.On-site pier piling method requires excessive time due to rebar reinforcement work, mold assembly work, and especially concrete hardening period on the foundation.

본 발명은 교량의 건설에 있어 교각의 구축기간이 길어짐으로 인해 전체 교량의 건설기간이 길어지는 것을 감안하여 교각을 조립식으로 구축토록 하여 단시간에 교각을 구축토록 하므로 말미암아 교량의 건설기간을 줄여 줄 수 있도록 한 조립식 교각 및 이에 대한 시공방법에 관한 것이다.The present invention can reduce the construction period of the bridge to build the bridge in a short time to build the bridge prefabricated in consideration of the longer construction period of the entire bridge due to the longer construction period of the bridge in the construction of the bridge. The present invention relates to a prefabricated bridge and a construction method thereof.

교량의 기초가 되는 교각은 통상 철근 콘크리트 구조물로 구성되며, 콘크리트의 경화기일에 따른 공사기간의 장기화를 볼 수 있다.The bridge piers, which are the foundation of the bridge, are usually composed of reinforced concrete structures, and can be seen to prolong the construction period depending on the hardening date of the concrete.

본 발명은 교각 구축을 현장 타설에 의한 콘크리트 구축공법이 아닌 공장에서 블럭형태로 콘크리트 교각을 조립식으로 미리 제작하고 이를 현장에서 조립 설치토록 하여 교각의 구축시간을 단축하므로 말미암아 교량의 전체 공사기간을 단축할 수 있도록 한 것이다.The present invention shortens the construction time of bridges by shortening the construction time of the bridges by pre-fabricating the concrete bridges in the form of blocks in the factory, not in the concrete construction method by placing the bridges in the form of blocks. It is to be done.

즉, 교각을 여러 조각의 콘크리트 블럭으로 조성하고 이를 미리 조성한 교각의 기초 위로 운반 조립 설치하여 교각의 구축을 단시간에 행할 수 있도록 한 것이다.In other words, the bridge was constructed by several pieces of concrete blocks and transported and installed on the foundation of the bridge in advance so that the construction of the bridge could be performed in a short time.

교량의 기초가 되는 교각을 구축함에 있어서, 먼저, 대상 지반 위에 다수개의 앵카볼트(12)를 돌출한 철근 콘크리트 기초 토대(11)를 조성하고, 상기 다수개의 앵카볼트(12)에 각각의 연결구(13)를 삽치 고정하며, 그 위에 내측에 다수개의 파이프(16)를 수직으로 삽치한 교각용 콘크리트 블럭(15)을 다단으로 쌓아 기둥을형성하며, 적층된 다단의 교각용 콘크리트 블럭(15) 맨 위에 역시 내측에 다수개의 파이프(19)를 수직으로 삽치한 교각 상부용 콘크리트 블럭(18)을 얹어 놓은 다음, 교각 상부용 콘크리트 블럭(18)의 내측에 삽치한 수직파이프(19) 및 교각을 구성하는 다단의 콘크리트 블럭(15) 내측의 수직파이프(16)를 관통하는 강봉(20)을 삽치하고, 상기 강봉(20)의 하단부의 나사산(21)을 상기 앵카볼트(12)에 체결한 연결구(13)에 체결 결합하며, 강봉(20)의 상단부의 나사산(22)에 플레이트(24)를 삽치하고, 너트(25)로 강봉(20)을 조여 기초 토대(11) 및 그 위에 다단으로 적층된 교각을 일체로 연결 구성토록 하는 것이다.In constructing the bridge pi which is the foundation of the bridge, first, a reinforced concrete foundation foundation 11 protruding from the plurality of anchor bolts 12 is formed on the target ground, and each of the connectors is connected to the plurality of anchor bolts 12. 13) is inserted and fixed, the pier concrete blocks (15) with a plurality of pipes (16) vertically inserted therein stacked in multiple stages to form a column, and stacked multi-tiered pier concrete blocks (15) top On top of that, a plurality of pipes 19 are vertically inserted with the pier upper concrete block 18 inserted therein, and then the vertical pipes 19 and the pier inserted inside the pier upper concrete block 18 are constructed. Inserting the steel bar 20 penetrating the vertical pipe 16 inside the multi-stage concrete block 15, and the threaded portion 21 of the lower end of the steel bar 20 to the anchor bolt 12 ( 13) is coupled to the upper end of the steel bar (20) To ever sapchi the plate 24 by the screw thread 22, a nut 25 connected to the rod 20 by tightening the base foundation 11 and a multi-stage stacked on the pier by integrally configured.

또한, 상기에 있어 기초 토대(11)와 콘크리트 블럭(15)사이, 콘크리트 블럭(15)과 블럭(15) 사이 및 콘크리트 블럭(15)과 교각 상부용 콘크리트 블럭(18) 사이에 모르타르 또는 에폭시수지 등의 그라우트층(31)을 형성토록 한 것이다.Further, in the above, mortar or epoxy resin between the base foundation 11 and the concrete block 15, between the concrete block 15 and the block 15, and between the concrete block 15 and the concrete block 18 for the pier upper part. The grout layer 31, etc. is formed.

이와 같이 현장의 지반에 교량의 초석이 되는 기초토대(11) 구축 당시 다수개의 앵카볼트(12)를 돌출되게 매립하며, 상기 돌출된 다수개의 앵카볼트(12) 내측에 나사산이 형성된 연결구(31)를 체결 조립하거나, 앵카볼트(12) 대신에 기초 토대(11)에 앵커너트를 삽치 고정할 수도 있다.In this way, at the time of construction of the foundation foundation 11, which becomes the cornerstone of the bridge on the ground of the site, a plurality of anchor bolts 12 are embedded to protrude, and the connector 31 is formed with a thread inside the projected plurality of anchor bolts 12. Fastener assembly, or instead of anchor bolt 12 may be fixed to the anchor nut to the foundation base (11).

이와 같이 기초토대(11) 위에 결합 체결수단으로 앵커볼트(13) 또는 앵커너트 등을 돌출 형성하고, 그 위에 내측에 다수개의 파이프(16)를 수직으로 매립한 콘크리트 블럭(15)을 임의 단수로 다단으로 적층하여 교각용 기둥을 조성할 때 콘크리트 블럭(15)과 블럭(15) 사이 또는 기초 토대(11) 사이에 모르타르 또는 에폭시수지 등의 그라우트층(31)을 형성하여 접합부위로 물이나 기타 이물질이 침투되지 못하도록 밀봉됨과 동시 접합력이 강화되어지게 된다.As described above, the anchor bolt 13 or the anchor nut is formed to protrude on the foundation base 11, and the concrete block 15 having a plurality of pipes 16 vertically embedded therein is formed in multiple stages. When forming a pillar for piers by stacking them, a grout layer 31, such as mortar or epoxy resin, is formed between the concrete block 15 and the block 15 or between the foundation base 11 so that water or other foreign substances are formed at the junction. It is sealed against penetration and strengthened at the same time.

이와 같이 다단으로 적층시킨 교각용 콘크리트 블럭(15)의 맨 상단의 교각 상부용 콘크리트 블럭(18) 내측에 삽치한 수직파이프(19) 및 교각용 콘크리트 블럭(15) 내측의 파이프(16)를 관통하는 각각의 강봉(20)을 삽치시킨 후, 강봉(20) 하단부의 나사산(21)을 앵카볼트(12)에 미리 체결한 연결구(13)에 체결하여 강봉(30)의 하단부를 고정토록 하며, 강봉(20)의 상단부의 나사산(22)에 플레이트(24) 및 너트(25)로 체결할 때 기초 토대(11)에 다단의 교각용 콘크리트 블럭(15) 및 교각 상부용 콘크리트 블럭(18)이 일체로 되어지게 되는 것이다. 그 후, 교각 상부 위에 슬리브나 보등을 조립하여 교량을 완성하게 되는 것이다.The vertical pipe 19 inserted into the pier upper concrete block 18 at the top of the pier concrete block 15 laminated in multiple stages as described above and the pipe 16 inside the pier concrete block 15 penetrated. After inserting each of the steel rods 20 to be fastened, the screw thread 21 of the lower end of the steel rod 20 is fastened to the connector 13 previously fastened to the anchor bolt 12 to fix the lower end of the steel bar 30, When fastening with the plate 24 and the nut 25 to the thread 22 of the upper end of the steel bar 20, the foundation base 11 has a multi-column pier concrete block 15 and a pier upper concrete block 18 It will be united. After that, a sleeve or beam is assembled on the top of the bridge to complete the bridge.

종래에 있어 교량용 교각은 형틀(거푸집)을 조성하고 이에 콘크리트를 부어 굳히는 현장 타설 콘크리트 공법을 사용하므로 말미암아 형틀 조립 및 해체시간, 보강용 철근 배근작업 및 이에 소비되는 시간 및 콘크리트 경화시간을 거쳐야만 비로서 교각이 완성되므로 인해 교각의 구축에 많은 기일이 소요되어 교량의 건설에 많은 기간이 소요됨을 볼 수 있으나, 본 발명에서와 같이 현장에서는 기초토대만 조성한 후, 그 위에 미리 공장에서 규격으로 제조된 내측에 파이프를 매립한 콘크리트 블럭을 규격 생산하고, 이를 현장으로 운반 설치함으로 인해 빠른시간내에 교각을 조립구축이 가능하게 되어 교량 건설기간을 단축하여 공사비를 절감할 수 있으며, 종래의 현장 타설에 의한 교각에 비해 강도 및 응력이 뒤떨어지지 않는 교각을 완성할 수 있는 아주 유용한 발명인 것이다.Conventionally, bridge piers use the site-casting concrete method of forming molds and pouring concrete to solidify them so that the molds can be assembled and dismantled, reinforcing reinforcing bars for reinforcement, and the time spent and concrete hardening. As the pier is completed, it can be seen that a lot of time is required for the construction of the bridge due to the completion of the construction of the bridge, but in the field as in the present invention, only the foundation is formed and then manufactured in advance in the factory on the factory. Standard production of concrete blocks with pipes embedded inside and transporting them to the site enables assembly and construction of bridge piers within a short time, which can shorten the construction period of the bridge and reduce construction costs. The bridge can be completed with less strength and stress than the bridge It will share useful inventions.
