Description

피에쓰씨 빔용 정착구 및 이를 이용한 거푸집 설치구조{ANCHOR FOR PSC BEAM}PSC beam anchorage device and formwork installation structure using same {ANCHOR FOR PSC BEAM}

본 고안은 교량 등을 시공할 때 사용되는 피에쓰씨 빔용 정착구 및 이를 이용한 거푸집 설치구조에 관한 것이다.The present invention relates to a PS C beam anchorage used when constructing bridges, etc. and a formwork installation structure using the same.

PSC 빔은 통상의 I형 단면의 빔 콘크리트 하부플랜지에 PSC 긴장재를 U자 형상으로 빔의 복부를 경유하여 단부에 긴장 후 정착시켜, 빔 자중을 포함한 설계 하중에 의한 휨 모멘트에 의하여 발생되는 인장응력을 상쇄시킬 수 있는 압축응력이 미리 빔 단면에 도입되도록 제작된 구조용 빔이라고 할 수 있다.PSC beam is a U-shaped PSC tension member in a beam concrete lower flange of a normal I-shaped cross section, which is tensioned and fixed at the end via the abdomen of the beam, and the tensile stress generated by the bending moment due to the design load including the beam weight. It can be said that the structural beam produced so that the compressive stress that can cancel the is introduced into the beam cross section in advance.

이러한 PSC 빔은 교량용 거더(Girder)로 이용되며, 교대 또는 교각에 설치되고 그 위에 슬래브가 형성되도록 하여 주로 30 ~ 40m 지간의 교량시공에 이용된다.These PSC beams are used as girders for bridges, and are installed in bridges or piers, and have slabs formed thereon, which are mainly used for bridge construction between 30 and 40 meters.

상기한 PSC 빔의 구조를 살피면 첨부 도면 도 1a 및 도 1b에 도시된 바와 같다. I형 빔의 양 끝단에 정착구(101)를 설치하고 상기 정착구(101) 사이에 긴장재(102)를 연결한 후 외부에 콘크리트 몰탈을 양생함으로써 PSC 빔(100)이 완성된다.Looking at the structure of the PSC beam described above is as shown in Figure 1a and 1b. The PSC beam 100 is completed by installing the anchors 101 at both ends of the I-beam, connecting the tension member 102 between the anchors 101, and curing the mortar to the outside.

상기 정착구(101)가 설치되는 부위에는 마무리 공사를 하기 위한 공간 부(105)가 형성된다. 정착구(101)와 긴장재(102)간에 연결마무리 공사가 끝나면 공간부(105)에 콘크리트 몰탈을 부어 양생한다.In the site where the fixing device 101 is installed, a space portion 105 for finishing construction is formed. After finishing the connection between the anchorage 101 and the tension member 102, the concrete part mortar is poured into the space 105 to cure.

종래에는 PSC 빔(100)의 측부로 고정부재(104)를 설치하고 철선(103)을 이용하여 공간부(105)의 전면으로 거푸집(106)을 밀착시켜 콘크리트를 부어 양생하였다.Conventionally, the fixing member 104 is installed on the side of the PSC beam 100 and the mold 106 is brought into close contact with the front of the space portion 105 using the iron wire 103 to pour concrete to cure.

이때, 거푸집(106)과 공간부(105) 사이에는 약간의 틈새(d)가 발생하게 된다. 이러한 틈새(d)는 철선(103)이 거푸집(106)의 양 끝단에 가하는 힘이 크기 때문에 거푸집(106)이 PSC 빔에 완전 밀착되지 않고 휨 현상이 발생하여 공간부(105)와 거푸집(106) 사이에 틈새(d)가 발생하였다.At this time, a slight gap d occurs between the formwork 106 and the space portion 105. Since the gap d has a large force applied to both ends of the formwork 106 by the steel wire 103, the formwork 106 does not come into close contact with the PSC beam and a warpage occurs, thereby causing the space portion 105 and the formwork 106 to be formed. There was a gap d) between).

상기와 같이 틈새(d)가 발생한 상태에서 콘크리트를 타설하면 틈새(d)로 콘크리트가 스며들어 양생 되므로 불규칙한 면을 갖는 단부가 형성된다.When the concrete is poured in the state in which the gap (d) occurs as described above, the concrete penetrates into the gap (d) and is cured, thereby forming an end portion having an irregular surface.

상기와 같이 불규칙한 단부를 갖는 PSC 빔을 교량용 거더로 사용할 경우 외관상 미려하지 못하다.As described above, when the PSC beam having the irregular end is used as the bridge girder, the appearance is not beautiful.

또한, 상기와 같이 거푸집을 철선으로 묶어 설치하여야 함으로써 거푸집의 설치에 따른 작업이 불편하다.In addition, the work according to the installation of the formwork is inconvenient because the formwork should be bundled with an iron wire as described above.

본 고안은 정착구를 이용하여 거푸집을 용이하게 설치함으로써, 작업성을 향상시킴과 아울러 마무리 공간부를 균일한 면을 갖게 콘크리트 몰탈을 타설함에 그 목적이 있다.The object of the present invention is to install the formwork using the anchorage, thereby improving the workability and placing the concrete mortar to have a uniform surface finish portion.

본 고안은 상기한 목적을 달성하기 위하여, 정착구는 긴장재가 삽입고정되게 관통공이 형성되며 동일 평면상에 거푸집을 고정하기 위한 체결수단이 구비된 헤드와, 상기 헤드를 지지하는 정착지압판과, 상기 정착지압판의 후단에 결합되며 콘크리트에 삽입되는 정착쐐기로 구성된다.The present invention, in order to achieve the above object, the fixing unit is a through-hole is formed in the tension material is inserted and fixed, the head is provided with a fastening means for fixing the formwork on the same plane, the fixing pressure plate to support the head, and the fixing It is coupled to the rear end of the pressure plate and consists of a fixing wedge inserted into the concrete.

본 발명의 다른 목적은 위의 정착구를 이용한 거푸집 설치구조에 있다. 이 설치구조는; 상기 체결수단으로서의 체결공과 일치하는 위치에 결합공이 타공된 거푸집을 PSC 빔의 양 끝단부에 대고; 상기 거푸집을 지지하기 위하여 상기 체결공과 일치하는 위치에 결합공이 타공된 지지판을 상기 거푸집 위에 받친 후; 상기 결합공 및 체결공에 볼트를 체결함으로써; 상기 거푸집을 고정시키게 되는 것을 특징으로 한다. Another object of the present invention is a formwork installation structure using the above anchorage. This installation structure is; Placing both ends of the PSC beam with the formwork with the coupling holes drilled at positions coinciding with the coupling holes as the fastening means; Supporting the formwork with a support plate with a coupling hole at the position corresponding to the fastening hole to support the formwork on the formwork; By fastening bolts to the coupling hole and the fastening hole; It is characterized in that the formwork is fixed.

본 고안은 정착구에 의해 거푸집을 안정적으로 고정설치하여 콘크리트를 타설함으로써, 초기에 양생한 콘크리트 면과 동일 평면상으로 콘크리트를 타설함으로써, 외관상 미려할 뿐만 아니라, 정착구를 이용하여 거푸집을 설치함에 있어 작업시간이 최소화되어 작업능률을 향상시킬 수 있다.The present invention stably installs the formwork by means of the anchorage to pour concrete, and by placing concrete on the same plane as the concrete surface cured at the beginning, it is not only beautiful in appearance but also works to install the formwork using the anchorage.

상기와 같은 구성으로 이루어진 정착구의 사용상태 및 정착구를 이용한 거푸 집 설치방법을 설명하면 다음과 같다.Referring to the state of use of the anchorage made of the configuration and the method of installing the formwork using the anchorage as follows.

먼저, I형 빔의 끝 단부에 긴장재(6)가 결속된 정착구(1)를 각각 설치하여 정착구 외의 부분은 콘크리트로 양생한다. 이때, 정착구(1)가 설치되는 부위에는 마무리 작업을 하기 위해 공간부(7)가 형성된다.First, the fixing fixtures 1, to which the tension member 6 is bound, are respectively provided at the end of the I-beam, and the portion outside the fixing apparatus is cured with concrete. At this time, the space portion 7 is formed in the site where the fixing fixture 1 is installed for finishing.

이러한 상태에서 공간부(7)에 내설된 정착구(1)와 긴장재(6)간에 결속 상태를 마무리 한 다음, 거푸집(11)을 설치하여 공간부(7)로 콘크리트를 타설하여 양생하면 된다.In this state, after the binding state between the anchorage 1 and the tension member 6 in the space portion 7 is finished, the mold 11 is installed to pour concrete into the space portion 7 to cure.

이러한 거푸집(11) 설치는 다음과 같이 행하면 된다. 공간부(7)의 폭과 동일하거나 크게 거푸집(11)을 형성한 상태에서 거푸집(11)을 공간부(7)로 끼워 거푸집(11)의 결합공(11a)과 정착구(1)의 체결수단(5)과 일치하도록 설치하면 된다.Such formwork 11 installation may be performed as follows. Fastening means of the coupling hole 11a of the formwork 11 and the fixing device 1 by inserting the formwork 11 into the space portion 7 in a state in which the formwork 11 is formed to be equal to or larger than the width of the space portion 7. It is good to install so that it matches (5).

그리고 거푸집(11)의 후단으로 지지판(12)을 밀착시켜 지지하되, 지지판(12)의 결합공(13)을 거푸집(11) 결합공(11a) 및 정착구(1) 체결수단(5)과 일치하도록 설치한다. 이러한 상태에서 볼트(B)를 이용하여 지지판(12) 및 거푸집(11)을 관통시켜 정착구(1)의 체결수단(5)에 끼워 고정하면 된다. 지지판(12)은 통상 합판으로 된 거푸집(11)의 강성을 보강하기 위한 것으로서 프레임 구조를 가진다. And support the support plate 12 in close contact with the rear end of the formwork 11, the coupling hole 13 of the support plate 12 coincides with the formwork 11, the coupling hole (11a) and the fastener (1) fastening means (5) Install it. In such a state, the support plate 12 and the formwork 11 may be penetrated by the bolt B to be fixed to the fastening means 5 of the fixing unit 1. The support plate 12 is for reinforcing the rigidity of the formwork 11 usually made of plywood and has a frame structure.

상기와 같이 거푸집(11)을 마무리 공간부에 완전 밀착함으로써 거푸집(11) 과 PSC 빔(10) 간에 틈새를 없앨 수 있으며, 콘크리트 타설시 콘크리트가 측면으로 스며들어 타설되는 것을 방지할 수 있다.By completely adhering the formwork 11 to the finishing space as described above, it is possible to eliminate the gap between the formwork 11 and the PSC beam 10, it is possible to prevent the concrete seeping into the side when pouring concrete.
