Description

콘크리트 제품 어셈블리Concrete product assembly
본 발명은 조립식 PC 암거 및 맨홀, 수로관 등의 콘크리트 제품 어셈블리에 관한 것이다.The present invention relates to prefabricated PC culverts and concrete product assemblies such as manholes, water pipes, and the like.
일반적으로, 도시의 지하 공간에는 배출되는 하수를 하수종말처리장으로 유도하거나 가정으로 전력 및 통신 서비스를 제공하는 케이블을 부설하기 위한 하수구, 전력구, 통신구, 공동구 등이 설치되는데, 도로 등을 파서 매설로를 형성하고, 일정한 장소에서 제작된 프리캐스트 콘크리트(PC)인 조립식 암거를 서로 연결하여 하수구, 전력구, 통신구, 공동구 등을 설치한다.In general, in the underground space of the city, sewers, electric power stations, communication districts, joint districts, etc. are installed to induce discharged sewage to sewage treatment plants or to lay cables providing electric power and communication services to homes. A buried road is formed, and the prefabricated culverts made of precast concrete (PC) are connected to each other to install sewers, electric power ports, communication ports, and joint holes.
상기와 같은 암거들은 도 1에 도시된 바와 같이 암거들은 서로 연결되는 형식으로 배열되어야 한다. 암거들을 각각 부설될 위치에 배열한 후, 밀착시켜 연결하게 된다.Such culverts should be arranged in such a way that culverts are connected to each other as shown in FIG. 1. The culverts are arranged in positions to be laid respectively, and then closely connected.
상기 각 암거들을 서로 밀착 고정시키기 위하여, 상기 암거의 모서리 부분에 암거의 길이방향으로 관통하며 서로 연통되는 홀을 형성 한 후, 상기 홀에 인장강선을 삽입한 후, 이를 당겨 암거들을 서로 압착 고정한다.In order to fix the culverts in close contact with each other, a hole penetrating in the longitudinal direction of the culvert and communicating with each other is formed in the corner portion of the culvert, and after inserting a tensile wire into the hole, the culverts are pressed and fixed to each other. .
이 때, 상기 암거의 내측면에 인장강선의 끝단이 노출되는 정착홀이 형성되어 인장강선의 끝단을 고정시키거나 당기는 작업이 가능하도록 이루어진다.At this time, a fixing hole is formed in the inner surface of the culvert exposed end of the tensile steel wire is made to secure or pull the end of the tensile steel wire.
또한, 상기 각 암거의 접합면에는 몰탈이 충진되어 수밀성을 향상시키도록 이루어진다.In addition, the bonding surface of each culvert is filled with mortar to improve the watertightness.
하지만, 종래와 같은 암거 체결방법은 다음과 같은 문제가 있다.However, the conventional culvert fastening method has the following problems.
첫째, 상기 인장강선이 상기 암거의 길이방향으로 구비되므로, 인장강선을 당기는 긴장작업시 당김량이 상대적으로 많아 상대적으로 많은 작업량이 필요한 문제가 있다.First, since the tensile steel is provided in the longitudinal direction of the culvert, there is a problem that a relatively large amount of work is required during the tensioning operation of pulling the tensile steel.
둘째, 상기 인장강선의 긴장작업시 이용되는 정착홀에서 상기 인장강선이 외부로 노출되므로, 부식방지를 위하여 상기 정착홀을 메우는 작업이 추가적으로 필요하다.Second, since the tensile steel is exposed to the outside in the fixing hole used during the tensioning of the tensile steel, it is necessary to additionally fill the fixing hole to prevent corrosion.
셋째, 상기 각 암거는 지반에 의해 지지되고 있는데, 도 2에 도시된 바와 같이, 상기 각 암거를 지지하는 지반에 부등침하가 발생한 경우, 어느 하나의 암거만 침하량이 크게 되어 해당 암거에 밀착력을 제공하는 인장강선에 큰 스트레스가 발생하고, 장시간 경과 시 크리프에 의해 인장강선이 늘어나게 된다. 따라서, 상기 인장강선의 장력이 약화되며 해당 암거의 밀착력이 약화된다. 상기와 같은 현상이 더욱 진행되면 암거와 암거 사이의 수밀이 파괴될 수 있으며, 그 사이로 지하수가 유입되어 인장강선이 부식을 야기하고, 이는 암거의 밀착력을 더욱 약화시키며 인장강선의 끊어짐으로 이어질 수도 있다.Third, each of the culverts are supported by the ground, as shown in Figure 2, when unequal settlement occurs in the ground supporting each of the culverts, only one of the culverts is largely settled to provide adhesion to the culverts A large stress is generated in the tensile steel, and the tensile steel is stretched by creep after a long time. Therefore, the tension of the tensile steel is weakened and the adhesion of the culvert is weakened. If the above phenomenon is further progressed, watertightness between the culvert and the culvert may be destroyed, and groundwater flows in between, causing the tensile steel to corrode, which may further weaken the adhesion of the culvert and lead to breakage of the tensile steel wire. .
넷째, 상기 인장강선이 삽입되는 홀을 형성할 때 상기 암거 내부에 배치되는 철근을 손상시켜 암거의 구조적 결함을 야기할 수 있는 우려가 있다.Fourth, there is a fear that when forming the hole into which the tensile steel wire is inserted may damage the reinforcing bar disposed inside the culvert may cause structural defects of the culvert.
다섯째, 상기 암거가 곡선부분으로 시공될 시에 상기 인장강선의 장력이 어느 일측에만 집중적으로 작용되어 암거간의 밀착력이 약화될 수 있으며, 상기 인장강선 또는 암거의 조기파손을 야기할 수도 있다.Fifth, when the culvert is constructed in a curved portion, the tension of the tensile wire is concentrated on only one side, so that the adhesion between the culvert may be weakened and may cause premature breakage of the tensile steel or culvert.
그리고, 상기한 문제는 암거에만 국한된 것이 아니라 맨홀 및 수로관등 콘크리트로서 분할된 부분품 형태로 기 제작되어 현장에서 조립 설치되는 콘크리트 제품 어셈블리의 설치에서도 공히 발생될 수 있다.In addition, the above problems are not limited to culverts, but may also occur in the installation of concrete product assemblies that are pre-fabricated in the form of divided parts as concrete, such as manholes and water pipes.

첫째, 종래의 인장강선이 암거의 길이방향으로 배치되는데 반하여, 본 발명은 암거의 높이 또는 폭 방향으로 배치되므로, 그 길이가 짧아질 수 있으며, 그에 따라 지반의 부등침하시 종래와 동일한 하중이 작용되어도 늘어나는 길이는 짧아질 수 있어 암거의 침하량이 최소화되며, 그에 따른 수밀 파괴현상 및 하수 유출, 지하수 유입, 인장강선의 부식 등도 최소화 시킬 수 있다.First, while the conventional tensile steel wire is arranged in the longitudinal direction of the culvert, the present invention is disposed in the height or width direction of the culvert, so that its length can be shortened, so that the same load as the prior art acts upon uneven settlement of the ground. The length of the culvert can be shortened even if it is minimized, thereby minimizing watertight destruction, sewage outflow, groundwater inflow, and corrosion of tensile steel.
둘째, 종래에는 암거를 밀착시킨 후 정착홀에 메움 작업이 필요하였지만, 본 발명에 따른 조립식 암거는 암거 중간의 정착홀이 구비되지 않으므로 해당작업이 필요 없어 작업성 및 생산성이 향상된다.Second, in the prior art, the culvert needs to be filled in the fixing hole after closely contacting the culvert, but the prefabricated culvert according to the present invention does not need the fixing hole in the middle of the culvert, and thus does not need the corresponding work, thereby improving workability and productivity.
셋째, 인장강선의 삽입을 위해 암거에 홀을 형성할 필요가 없으므로, 암거 내부에 배치된 철근이 손상될 우려가 없다.Third, since there is no need to form a hole in the culvert for the insertion of the tensile steel wire, there is no fear that the rebar disposed inside the culvert is damaged.
넷째, 암거가 곡선으로 시공될 시에도 직선부분과 동일한 밀착력을 제공할 수 있어 인장강선 및 암거의 조기파손이 방지된다.Fourth, even when the culvert is constructed in a curved line can provide the same adhesion as the straight portion to prevent premature failure of the tensile steel wire and culvert.
다섯째, 인장강선의 강선고정장치와 결합되는 부분이 와이어 로프가 아닌 PC강연선으로 이루어져 있어 강선고정장치와의 고정력이 증대되며, 그 외의 부분은 와이어로프로 이루어져 있어 휨이 자유로워 작업이 보다 수월해지는 효과가 있다.Fifth, the part combined with the steel wire fixing device of the tensile steel wire is composed of PC steel wire instead of the wire rope, so that the fixing force with the steel wire fixing device is increased, and the other parts are made of the wire rope so that the bending is free and the work becomes easier. It works.
여섯째, 인서트 너트에 보강플랜지 및 응력분산리브가 구비되므로, 인서트 너트의 주면에 가해지는 힘이 집중되지 않고 분산되어 인서트 너트 및 인서트 너트가 매립된 콘크리트 제품의 파손이 방지된다.Sixth, since the insert nut is provided with a reinforcing flange and stress distribution ribs, the force applied to the main surface of the insert nut is not concentrated and dispersed, thereby preventing the insert nut and the insert nut embedded concrete product from being damaged.
일곱째, 체결부 주위에 형성된 전단방지블록 형성홈에 의해 전단방지블록이 형성되므로 체결부가 보호받을 수 있고, 이에 더하여 전단방지블록이 제1본체블록 및 제2본체블록의 결합면이 전단방향으로 엇갈리는 것을 방지하는 효과가 있다.Seventh, the shear preventing block is formed by the shear preventing block forming grooves formed around the fastening portion, so that the fastening portion can be protected. In addition, the shear preventing block has a coupling surface of the first body block and the second body block that are staggered in the shear direction. It is effective to prevent that.
여덟째, 접합면에 플러그 키 및 상기 플러그 키가 삽입되는 인서트 너트가 구비되므로, 결합시 상기 플러그 키가 인서트 너트에 먼저 삽입되면서 상기 제1암거와 제2암거의 결합이 안내되며, 결합된 후에는 상기 플러그 키가 상기 제1암거와 제2암거가 상하방향 또는 좌우방향으로 이동하는 것을 방지하는 효과가 있다.Eighth, since a plug key and an insert nut into which the plug key is inserted are provided at the joining surface, the coupling of the first culvert and the second culvert is guided while the plug key is first inserted into the insert nut. The plug key has an effect of preventing the first and second culverts from moving in the vertical direction or the left and right directions.

그리고, 상기 인장강선(300)의 일측 끝단부를 제1고정볼트(130)에 형성된 관통홀의 나사부 반대측으로부터 삽입시킨 후 강선고정장치(310)을 인장강선(300)의 끝단에 삽입하고 인장강선(300)을 당겨 강선고정장치(310)가 제1고정볼트(130)에 삽입되도록 하고 상기 제1고정볼트(130)를 상기 제1암거(100)의 맨 하측의 인서트 너트(110)에 체결한다. Then, one end of the tensile steel wire 300 is inserted from the opposite side of the threaded portion of the through-hole formed in the first fixing bolt 130, and then the steel wire fixing device 310 is inserted into the end of the tensile steel wire 300 and the tensile steel wire 300 Pull) so that the steel wire fixing device 310 is inserted into the first fixing bolt 130, and the first fixing bolt 130 is fastened to the insert nut 110 of the bottom of the first culvert 100.
그리고, 도 10에 도시된 바와 같이, 유압잭(400) 등의 별도 기구를 사용하여 인장강선(300)의 타측으로 당겨 긴장시킨다. 긴장된 인장강선(300)은 팽팽하게 당겨지며 그에 따라 상기 제1암거(100)와 제2암거(200)가 서로 밀착된다.And, as shown in Figure 10, by using a separate mechanism such as the hydraulic jack 400 to pull to the other side of the tensile steel wire 300 to tension. The tensioned tensile steel wire 300 is pulled taut and thus the first culvert 100 and the second culvert 200 are in close contact with each other.
상기 제1암거(100)와 제2암거(200)가 충분히 밀착된 후엔 유압잭(400)으로 당겨진 인장강선(300)의 타단을 절단한 후에 도 11에 도시된 바와 같이, 그 끝단에 강선고정장치(310) 및 지지탭(320)을 설치한다.After the first culvert 100 and the second culvert 200 are sufficiently in close contact with each other, the other end of the tensile steel wire 300 drawn by the hydraulic jack 400 is cut, as shown in FIG.
