Abstract

PURPOSE: A doubling method of a synthetic resin well mold form is provided to bear up the pressure generated during concreting by supporting from the outside. CONSTITUTION: A base plate(11) as an external form is made of synthetic resins. The height of the base plate is a little higher than an internal form and the length is about 3cm shorter than the internal form. Struts(12) are arranged around the external form at regular intervals, and nails are driven from the inside to the outside. After the assembly of the internal form is finished, the external form is installed, and then steel wires(14) are installed. At a connection point, a turnbuckle is installed to correspond to expansion force. A reinforcing plate is installed at a weak point, and panels are connected by reinforcing bolts.

Description

합성수지계 우물통 거푸집의 2중화 공법{Method duplication casen mold of resin genealogy}Method of duplication casen mold of resin genealogy

본 발명은 교량의 하부구조 우물통 기초를 시공할 때 사용되는 합성수지계 거푸집의 보강 공법에 관한 것으로, 타설하는 콘크리트의 압력을 견디도록 외부에서 지지하여 주는 내, 외부 복합 거푸집에 관한 것이다.The present invention relates to a method of reinforcing a synthetic resin formwork used when constructing the foundation of a bridge bottom well, and to an internal and external composite formwork supported externally to withstand the pressure of concrete to be poured.

최근 교량의 하부구조인 우물통의 세굴방지와 미관확보 및 유지관리의 용이성을 위하여 거푸집을 합성수지계를 사용하고, 콘크리트 타설 후에도 거푸집 제거를 하지 않는 일체화 공법을 사용하면서 외부 미관의 확보와 유수의 마찰저항을 감안하여 내부에서 프레임과 스트럭쳐를 구성하고 있으나 콘크리트 타설 압력을 견디는데는 한계가 있었다. 이에 따라 콘크리트 타설 시에 많은 회수로 나누어 타설을 해야 하므로 작업성이 저하되고, 또 타설 중 접합부의 파손으로 콘크리트가 유출되어 강을 오염시키거나, 슬러지 제거나 사후 수습에 많은 비용이 투입되었다.Recently, the synthetic resin system is used for the formwork for the prevention of scouring, the aesthetics, and the maintenance of the well, which is the substructure of the bridge. Frames and structures were constructed internally in consideration of resistance, but there was a limit in enduring concrete pouring pressure. As a result, when the concrete is poured, the workability is reduced because of the large number of times, and the concrete flows out due to the breakage of the joints during the pouring, which contaminates the steel, or the sludge is removed or the post-installation is expensive.

아울러 콘크리트 타설 시 내부의 프레임이나 스트럭쳐에 문제가 발생되어도 내부에 사람이 들어가서 보강을 할 수 없기 때문에 타설을 중단하고 경화가 약간 진행되기를 기다렸다가 이어치기를 할 수 밖에 없고, 여기서 발생하는 블리이딩이나 레이탄스로 인해 신구 콘크리트의 일체화에 새로운 문제를 야기할 수도 있다.In addition, even if there is a problem with the internal frame or structure during concrete pouring, people cannot enter and reinforce the interior, so they have to stop the pouring and wait for the hardening to proceed a little, and then continue bleeding or laying Tans may cause new problems in the integration of old and new concrete.

현장에서 조립되면서 상하와 좌우로 접합되는 부분에서 프렌지의 두께를 두텁게 하고 볼트로 조임을 하며 내부에 여러 형태의 보강재를 조합하여 외부에서 내부로 작용하는 수압에는 충분히 견딜 수 있도록 설계 및 제작되어 있으나, 내부에 콘크리트가 타설될 때 순간적으로 발생하는 유동성 충격과 중량에 의해서 생겨나는 팽창 압력에 견디기 위하여 부재의 두께를 두텁게 하여야 하므로 경제성에서 문제가 될 수 밖에 없었던 것이다.While assembled at the site, the thickness of the flange is thickened at the part joined up and down and left and right, and it is designed and manufactured to withstand the water pressure acting from the outside to the inside by combining various types of reinforcement inside. In order to withstand the expansion pressure caused by the flow shock and the weight generated when the concrete is poured inside, the thickness of the member has to be thickened, which is a problem in economics.

따라서 본 발명은 일체화되는 합성수지계 거푸집과 내부의 프레임 및 스트럭쳐를 콘크리트 타설 완료시점까지 수압에 견딜 수 있는 정도의 구조와 두께로 하고 콘크리트 타설 시의 유동압과 팽창압은 재사용 가능한 외부 거푸집에서 대응하도록 하여 시공성과 경제성을 확보하고자 하는 우물통 공사의 내, 외부 2중화 거푸집을 제공하려는 것이다.Therefore, the present invention has a structure and thickness that can withstand the hydraulic pressure until the concrete casting form and the internal frame and structure to be integrated, and the flow pressure and expansion pressure during the concrete placing correspond to the reusable external formwork. In order to secure construction and economic feasibility, the company intends to provide internal and external doubled formwork for well construction.

간단하게는 거푸집의 단위높이가 크지 않을 때 보강하는 방법으로는 가장 취약한 부분인 사면 접합부분에서는 외부에 지지판을 설치하고 접합되는 각각의 판넬과 볼트로 체결하여 팽창압에 의한 변형에 대응토록 한다.In the simple method of reinforcing when the unit height of the formwork is not large, the slope connection part, which is the most vulnerable part, is provided with a support plate on the outside and fastened with each panel and bolt to be joined to cope with deformation due to expansion pressure.

그러나 이러한 보강은 한계가 있어서 불규칙한 타설압력에 의한 수지 판넬의 요철발생이나 힘의 균형을 확보하기 위한 수지의 두께를 과다 계상함으로 인한 비용증가를 막을 수는 없으므로 내부체결의 일체형 수지 거푸집은 콘크리트 양생 후의 쇄굴방지와 충격에만 적합하게 설계를 하고, 콘크리트 타설시의 압력에 대응은 재사용 가능한 외부거푸집으로 하도록 하여 거푸집의 파손 사고와 내부용 거푸집의 두께 확대로 인한 비용을 절감토록 한 것이다.However, this reinforcement has limitations, so it is not possible to prevent the cost increase due to the occurrence of irregularities in the resin panel due to irregular placing pressure or the excessive thickness of the resin to secure the balance of force. It is designed to prevent crushing and impact only, and to cope with the pressure when placing concrete is to use reusable external formwork to reduce the cost of accidental damage of formwork and increase the thickness of internal formwork.

상기와 같이 우물통의 쇄굴을 방지하기 위하여 합성수지계 재료를 사용하는 일체형 거푸집에 있어서 각각의 판넬 조각의 연결부위에서 콘크리트 타설시 발생하는 거푸집 파손사고를 방지하기 위하여 간단하게는 가장 취약부위인 사각 연결부분에 보강판(4)을 대고 각각의 판넬에 보강볼트(5)를 연결하는 방법을 사용한다.In the one-piece formwork using synthetic resin material to prevent the crushing of the wells as described above, the rectangular connection part, which is simply the most fragile part, in order to prevent the form breakage accident occurring when concrete is poured at the connection part of each panel piece. Place the reinforcement plate (4) on the method to connect the reinforcement bolt (5) to each panel.

이와 같이 보강 리벳팅을 하면 콘크리트 타설시 발생되는 팽창압력(6)과 일체형 거푸집의 인장력에 의해서 생기던 수직 프랜지(7)의 변형(9) 및 이로 인한 수평 프랜지(8)의 변형(10)을 방지할 수 있으므로 거푸집 파손사고를 방지할 수 있다.The reinforcing riveting thus deforms the deformation 9 of the vertical flange 7 and the deformation 10 of the horizontal flange 8 caused by the expansion pressure 6 and the tension of the integral formwork, which are generated during concrete pouring. As it can prevent, it can prevent form breakage accident.

보강 리벳으로는 한계가 있으므로 외부용 거푸집을 제작 사용토록 한다. 기본판(11)은 합성수지로 평판을 만드는데 높이는 내부용 거푸집의 높이보다 조금 더 높게 하여 내부 거푸집의 상하 연결지점(8)에서 콘크리트 이어치기 상황이 발생하지 않도록 하고 길이는 내부 거푸집의 둘레길이보다 3cm 정도 작게 하여 유격을 갖도록 제작한다. 여기에 적당한 간격으로 버팀(12)목을 배치하고 안에서 밖으로 못(13)을 박는다. 현장에서 일체형 내부 거푸집(1)이 조립된 후 외부용 거푸집(11)을 둘러친 다음 50cm 의 간격으로 스틸 와이어(14)를 설치하고 연결지점에서 덤버클(15)을 이용하여 팽창력(6)에 대응을 하도록 한다.Reinforcement rivets have limitations, so make external formwork. The base plate 11 is made of synthetic resin, the height of which is slightly higher than the height of the internal formwork, so that the concrete joint situation does not occur at the upper and lower connecting points 8 of the internal formwork, and the length is 3cm than the circumferential length of the internal formwork. Make it small enough to have a play. Arrange the braces (12) at appropriate intervals here and nail the nails (13) out from the inside. After the integrated internal formwork (1) is assembled at the site, it surrounds the external formwork (11) and then installs the steel wires (14) at intervals of 50 cm. Make a response.

이러한 외부용 거푸집은 하부 타설이 끝나면 상부로 끌어 올려 계속 재사용토록 하고 판넬(11) 자체에는 힘을 받지 않으므로 우물통의 크기에 맞추어 절단 또는 연장하여 다른 현장에서도 반복 사용 가능하도록 한다.This external formwork is pulled to the top to continue reuse when the bottom is finished, and because the panel (11) itself does not receive the force to cut or extend to fit the size of the well can be used repeatedly in other sites.

이와 같은 본 발명에 의하면 간단한 보강 리벳(4)으로 내부 거푸집 파손이 우려되는 취약지점이 보강 될 수 있으며, 일체형 내부 거푸집의 타설 압력에 견디기 위한 두께 확대에 따른 비용도 절약할 수 있고, 타설압력에 의한 표면 요철 발생도 제지할 수 있어 우물통 기초의 거푸집 설치 방법으로 유용성을 확보할 수 있게 된다.According to the present invention as described above, a weak reinforcing point can be reinforced with a simple reinforcing rivet 4, and the cost of expanding the thickness to withstand the pressure of the integral internal formwork can be saved, and The surface irregularities caused by this can also be restrained, and thus the usability can be secured by the method of installing the formwork based on the well.
