Description

빔과 필러의 접합 구조{BEAM-PILLAR JOINT CONSTRUCTION}Beam and filler joint structure {BEAM-PILLAR JOINT CONSTRUCTION}

본 발명은 빔과 필러의 접합 구조에 관한 것이다.The present invention relates to a joint structure of a beam and a filler.

프리스트레스트(prestressed) 콘크리트 부재를 조합시켜 구축한 프리스트레스트 콘크리트 구조물은, 도 3에 나타낸 바와 같이, 기초(20) 상에 세워 설치된 복수개의 프리캐스트 콘크리트 필러(21)의 빔 지지용 턱(22)에, 단부(端部)의 돌출부(23)를 지지시켜 프리캐스트(precast) 콘크리트 빔(24)이 각 필러(pillar) 사이에 걸쳐지고, 이들 프리캐스트 콘크리트 빔(24)에 PC 강선(鋼線)(25)에 의해 프리스트레스트가 부여되어 구축되어 있다.As shown in FIG. 3, the prestressed concrete structure constructed by combining the prestressed concrete members is a beam supporting jaw 22 of the plurality of precast concrete pillars 21 which are mounted on the foundation 20. In order to support the protrusion 23 at the end, a precast concrete beam 24 is interposed between the pillars, and a PC steel wire is applied to these precast concrete beams 24. Prestress is provided and constructed by (25).

이 프리스트레스트 콘크리트 구조물에 있어서의 빔(24)과 필러(21)는, 도 3에 나타낸 바와 같이, 접합부에 모르타트(21)를 개재시켜 접합되어 있다.As shown in FIG. 3, the beam 24 and the filler 21 in this prestressed concrete structure are joined by the mortar 21 through the joining part.

그러나, 이 프리스트레스트 콘크리트 구조물은, 이른바 직하형(直下型) 지진 등에 의한 연직력(鉛直力)에 의해, 빔과 필러의 접합부에 있어서의 빔 지지용 턱이 파손된다는 문제가 있었다.However, this prestressed concrete structure has a problem that the beam supporting jaw at the junction of the beam and the filler is damaged by the vertical force caused by a so-called direct earthquake or the like.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것이며, 그 목적은, 프리스트레스트 콘크리트 구조물의 빔과 필러의 접합부에 있어서의 빔 지지용 턱이, 이른바 직하형 지진 등에 의한 연직력에 의해 파손되지 않도록 한 것이다.The present invention has been made to solve the above problems, and its object is to prevent the beam supporting jaw at the junction of the beam and the pillar of the prestressed concrete structure from being damaged by the vertical force due to the so-called direct earthquake or the like. It is.

이상의 문제점을 해결하기 위한 수단은, 기초 상에 복수개 세워 설치된 프리캐스트 콘크리트 필러의 빔 지지용 턱에, 단부의 돌출부가 지지되어 프리캐스트 콘크리트 빔이 각 필러 사이에 걸쳐지고, 이들 프리캐스트 콘크리트 빔에 PC 강선에 의해 프리스트레스트가 부여되고, 프리캐스트 콘크리트 필러에 긴장(緊張) 정착된 빔과 필러의 접합 구조에 있어서, 상기 빔 지지용 턱과 프리캐스트 콘크리트 빔 단부의 돌출부의 접합부에, 상기 돌출부의 길이를 넘지 않는 범위에서 충격 완충재를 개재시키는 동시에, 상기 충격 완충재를 제외한 다른 접합부에 프리캐스트 콘크리트 필러 및 프리캐스트 콘크리트 빔보다 낮은 강도의 모르타르를 개재시키고, 상기 충격 완충재는 경질(硬質) 고무판, 연판(鉛版) 또는 연판과 경질 고무판을 조합한 것임을 특징으로 하는 것이다.Means for solving the above problems are supported by the beam supporting jaws of the precast concrete pillars, which are erected on a plurality of foundations, so that the projections at the ends are supported so that the precast concrete beams are interposed between the pillars. In the joining structure of the beam and the pillar by which the prestress is provided by the PC steel wire and tension-fixed to the precast concrete pillar, the joining part of the projection of the beam support jaw and the precast concrete beam end part is carried out. The impact buffer material is interposed within the range not exceeding the length, and the mortar of lower strength than the precast concrete filler and the precast concrete beam is interposed between the joints other than the shock buffer material. (鉛版) or a combination of a soft plate and a hard rubber plate It is.

프리스트레스트 콘크리트 구조물이, 이른바 직하형 지진에 의한 연직력을 받았을 경우, 빔과 필러의 접합부에 있어서의 충격 완충재에 의해 연직력을 흡수함으로써 빔 지지용 턱의 파손을 방지할 수 있다.When the prestressed concrete structure is subjected to a vertical force due to a so-called direct type earthquake, damage to the beam supporting jaw can be prevented by absorbing the vertical force by the impact buffer at the joint between the beam and the filler.

충격 완충재를 수지 모르타르, 연판, 연판과 경질 고무판을 조합시켜 형성한 것에 의해 연직력 등의 외력을 효과적으로 흡수한다.The impact buffer is formed by combining a resin mortar, a soft plate, a soft plate, and a hard rubber plate to effectively absorb external forces such as vertical force.

이하, 본 발명의 실시예의 일례를 도면을 참조하여 상세하게 설명한다. 도 1은 프리캐스트 콘크리트 필러와 프리캐스트 콘크리트 빔의 접합부를 나타낸 단면도이다.EMBODIMENT OF THE INVENTION Hereinafter, an example of embodiment of this invention is described in detail with reference to drawings. 1 is a cross-sectional view showing a junction of a precast concrete filler and a precast concrete beam.

프리캐스트 콘크리트 필러(1)가 시트 블록(2)에 PC 강봉(鋼棒)(3)과 접합되어 기초 콘크리트(4) 상에 세워 설치되어 있다. 이 프리캐스트 콘크리트 필러(1)에는 PC 강봉(3) 또는 PC 강선(5)에 의해 미리 프리스트레스트가 부여되고, 소정의 높이로 빔 지지용 턱(6)이 일체로 형성되어 있다.The precast concrete filler 1 is joined to the PC steel bar 3 to the sheet block 2, and is mounted on the foundation concrete 4, and is installed. A prestress is previously given to the precast concrete filler 1 by the PC steel bar 3 or the PC steel wire 5, and the beam support jaw 6 is integrally formed at a predetermined height.

빔 지지용 턱(6)에는 프리캐스트 콘크리트 빔(7) 단부의 돌출부(8)가 지지되어, 프리캐스트 콘크리트 빔(7)이 각 필러 사이에 걸쳐져 있다.The projections 8 at the end of the precast concrete beam 7 are supported by the beam supporting jaw 6, and the precast concrete beam 7 is interposed between the pillars.

프리캐스트 콘크리트 빔(7)의 길이 방향의 상부 및 하부에는 상부 PC 강선(5a) 및 하부 PC 강선(5b)이 미리 매설되어 있다. 상부 PC 강선(5a)의 단부가 프리캐스트 콘크리트 빔(7)의 돌출부(8)로부터, 또 하부 PC 강선(5b)의 단부가 빔 지지용 턱(6)으로부터 프리캐스트 콘크리트 필러(1)를 관통하여 소정의 근장력(筋張力)이 부여되는 것에 의해, 프리캐스트 콘크리트 빔(7)에 프리스트레스트가 부여 되어 접합된다.The upper PC steel wire 5a and the lower PC steel wire 5b are previously embedded in the upper part and the lower part of the longitudinal direction of the precast concrete beam 7. The end of the upper PC steel wire 5a penetrates the precast concrete pillar 1 from the protrusion 8 of the precast concrete beam 7 and the end of the lower PC steel wire 5b from the beam supporting jaw 6. By applying a predetermined strength, the prestress is applied to the precast concrete beam 7 and joined.

이 프리캐스트 콘크리트 빔(7)과 프리캐스트 콘크리트 필러(1)의 접합부에는 충격 완충재(9)가 설치되어 있다. 이 충격 완충재(9)는 경질 고무이며, 프리캐스트 콘크리트 빔(7)의 돌출부(8)의 길이를 넘지 않는 범위에 있어서 설치되는 동시에, 상기 충격 완충재를 제외한 다른 접합부에는 프리캐스트 콘크리트 빔(7) 및 프리캐스트 콘크리트 필러(1)보다 낮은 강도의 모르타르(10)가 충전되어 있다.An impact buffer 9 is provided at the junction of the precast concrete beam 7 and the precast concrete filler 1. The shock absorbing material 9 is made of hard rubber and is provided in a range not exceeding the length of the protrusion 8 of the precast concrete beam 7, and the precast concrete beam 7 is provided at other joints except for the shock absorbing material. And a mortar 10 having a lower strength than the precast concrete filler 1 is filled.

이와 같이, 프리캐스트 콘크리트 빔(7)과 프리캐스트 콘크리트 필러(1)의 접합부는 충격 완충재(9)를 상부 PC 강선(5a)과 하부 PC 강선(5b)으로 협지한 상태로 형성되어 있으므로, 이 접합부가 플렉시블하게 되는 동시에 충격 완충재(9)에 의해 외력을 흡수한다.Thus, since the junction part of the precast concrete beam 7 and the precast concrete filler 1 is formed in the state which clamped the impact buffer material 9 by the upper PC steel wire 5a and the lower PC steel wire 5b, The joint becomes flexible and absorbs external force by the impact buffer 9.

충격 완충재(9)는 경질 고무 외에, 도 2에 나타낸 바와 같이, 경질 고무판(11)과 연판(12)을 중첩시킨 것이라도 된다. 그 외에, 충격 완충재(9)는 연판 또는 수지 모르타르로 형성할 수도 있고, 또 이들을 조합시켜 형성할 수도 있다.In addition to the hard rubber, the shock-absorbing material 9 may superimpose the hard rubber plate 11 and the soft plate 12 as shown in FIG. In addition, the impact buffer 9 may be formed of a soft plate or a resin mortar, or may be formed by combining them.

이와 같이, 프리캐스트 콘크리트 빔(7)과 프리캐스트 콘크리트 필러(1)를 충격 완충재(9)를 개재시켜 접합한 것에 의해, 상기 충격 완충재(9)에 의해 이른바 직하형의 대지진 등에 의한 연직력을 흡수하여 프리캐스트 콘크리트 필러(1)에 있어서의 빔 지지용 턱(6)의 파손을 방지한다.Thus, by joining the precast concrete beam 7 and the precast concrete filler 1 via the impact buffer 9, the vertical shock force by what is called a direct earthquake etc. by the said impact buffer 9 is carried out. It absorbs and prevents damage of the beam support jaw 6 in the precast concrete filler 1.
