Description
본 발명은 PC공동주택의 PC공법에 관한 것으로서, 보다 상세하게는 프리캐스트 콘크리트 라멘구조의 공동주택 시공 중 고층의 높이에서 조립되는 프리캐스트 콘크리트 기둥과 보를 간단한 상부작업만으로 부재를 결속하여 별도의 외부 가설 구조물을 설치하지 않고도 시공성 및 작업자의 안전성을 확보하고 중량 부재의 탈락에 의한 건축 구조물의 연속붕괴를 방지할 수 있도록 하는 조립 시 연속붕괴를 방지하는 연결유닛을 이용한 PC공동주택의 PC공법에 관한 것이다.The present invention relates to a PC construction method of a PC apartment building, and more specifically, to a PC construction method of a PC apartment building using a connecting unit that prevents continuous collapse during assembly, which enables precast concrete columns and beams assembled at a high height during the construction of an apartment building with a precast concrete frame structure to be connected by simple upper work, thereby ensuring constructability and worker safety without installing a separate external temporary structure, and preventing continuous collapse of the building structure due to detachment of heavy members.
일반적으로, 프리캐스트 콘크리트(Precast concrete, 이하 PC) 라멘 구조는 사전 제작된 보와 기둥을 현장에서 접합하도록 구성된다. 따라서, 제작 및 시공 과정에서 각각의 오차가 발생할 수 있고, 이를 최소화할 수 있는 기술이 요구된다.In general, precast concrete (PC) frame structures are constructed by joining prefabricated beams and columns on site. Therefore, errors may occur during the manufacturing and construction processes, and technology is required to minimize these errors.
특히, 국내 공동주택에 적용할 경우 벽식 무량판 구조에 비해 경쟁력을 갖기 위해, 층고절감 및 장스팬 등의 형상이 요구되고, 접합부 품질 또는 시공오차 등이 하자 요인이 되므로 일반적인 건축물에 비해 세심한 고려가 필요하다.In particular, when applied to domestic apartment complexes, in order to be competitive compared to wall-type flat-plate structures, shapes such as reduced floor height and long spans are required, and since defects such as joint quality or construction errors can be factors, more careful consideration is required compared to general buildings.
PC 부재를 제작 시, 외형 또는 크기 등의 치수는 비교적 오차가 적으나, 매입물, 특히 철근의 경우 간격재 또는 결속선으로 고정시키나 콘크리트 타설 과정에서 위치 이동으로 인한 오차가 큰 편이다.When manufacturing PC members, the dimensions such as the shape or size have relatively little error, but in the case of embedded materials, especially rebar, they are fixed with spacers or tie lines, but the error due to positional movement during the concrete pouring process is large.
일반적으로 PC 라멘 구조를 조립할 때는, 기둥을 먼저 세우고, 보를 기둥에 고정하는데, 보를 기둥에 고정하는 방법으로는 동바리로 보 단부를 지지하는 방식과, 기둥에 브라켓을 만들어 보 단부를 지지하는 방식이 있다.Generally, when assembling a PC frame structure, the columns are erected first and then the beams are fixed to the columns. There are two methods for fixing the beams to the columns: supporting the ends of the beams with brackets, and supporting the ends of the beams by creating brackets on the columns.
상기 종래기술은 탈부착이 가능한 브라켓을 적용할 경우에도 중량이 커서, 인력에 의한 작업이 불가한데, 고층의 경우 외부 장비 이용이 어려우므로 시공성이 좋지 않은 문제가 있고, 또한 라멘구조의 경우, 외벽을 마감재로 형성하기 때문에 추락의 위험이 높고, 고층에서 부재 탈락은 저층으로의 연속적인 붕괴를 일으킬 가능성이 큰 문제가 있었다.The above-mentioned conventional technology has a problem in that even when a detachable bracket is applied, the weight is large and work by manpower is impossible, and in the case of high-rise buildings, it is difficult to use external equipment, so there is a problem in that the constructability is poor, and in addition, in the case of a frame structure, since the exterior wall is formed with a finishing material, there is a high risk of falling, and there is a problem in that the detachment of a member from a high-rise building is highly likely to cause continuous collapse to a lower floor.
이러한 문제를 해결하기 위해 도 1에서 보는 바와 같이 일반적으로 보 단부에 크게 돌출된 기둥 브라켓이나 선시공된 RC벽체의 걸침부위를 블럭아웃 하는 방법이 사용되었으나, 이는 공동주택의 하부 천장 마감과 간섭으로 인한 공간의 효율성을 크게 저하시키고 블럭아웃으로 인한 수직재의 단절로 인한 구조적 안전성을 해치는 문제가 있었다.To solve these problems, as shown in Fig. 1, a method of blocking out a column bracket that protrudes greatly from the end of a beam or a hanging part of a pre-constructed RC wall has been used, but this method has the problem of significantly reducing the efficiency of space due to interference with the lower ceiling finish of an apartment building and damaging structural safety due to the disconnection of vertical materials caused by the blocking out.
또한, 동시에 진행되는 PC부재간 접합과 달리 RC벽체는 선행되고 PC부재가 후시공으로 접합되므로 부재간 접합부의 정밀도가 확보되지 않으면 현장에서 수정 또는 보완작업이 필요하다. 이러한 수정 또는 보완작업은 공사기간 지연이나 구조적 부실을 일으키는 원인이 되기도 한다.In addition, unlike the simultaneous jointing of PC members, RC walls are constructed first and PC members are joined after construction, so if the precision of the joints between members is not secured, on-site modification or supplementary work is required. Such modification or supplementary work can cause delays in the construction period or structural failure.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 RC벽체와 PC보 사이에 돌출되는 부분이 없도록 하여 건축물의 층고를 확보하여 사용성 및 경제성을 크게 향상시킬 수 있도록 하는 연결유닛을 이용하여 RC벽체와 PC보를 연결하기 위한 PC공동주택의 PC공법을 제공하는데 있다. The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a PC method for a PC apartment complex for connecting an RC wall and a PC beam using a connecting unit that secures the floor height of a building by preventing any protruding portion between the RC wall and the PC beam, thereby greatly improving usability and economy.
본 발명의 다른 목적은 RC벽체와의 접합 시 오차흡수가 가능하여 구조적 성능이 확보되면서 조립 시 탈락에 대한 시공 안전성을 확보할 수 있는 RC벽체와 PC보를 연결하기 위한 PC공동주택의 PC공법을 제공하는데 있다. Another object of the present invention is to provide a PC method for connecting a PC wall and a PC beam of a PC apartment building, which can secure structural performance by allowing error absorption when joining with an RC wall, while ensuring construction safety against detachment during assembly.
상기한 목적을 달성하기 위한 본 발명의 일 측면에 따르면, 상향 걸림판부가 측방향에 노출되도록 제1연결유닛이 매립되는 RC벽체를 설치하는 1단계와, 상향 걸림판부와 대면 조립되는 하향 걸림판부가 측방향에 노출되도록 제2연결유닛이 매립되는 PC보를 제조하는 2단계와, 제1연결유닛의 상향 걸림판부에 제2연결유닛의 하향 걸림판부가 대면하도록 걸쳐져 PC보의 중력방향 하중이 지지되도록 조립하는 3단계 및 PC보 상부에 토핑 콘크리트를 타설하는 4단계를 포함하는 연결유닛을 이용하여 RC벽체와 PC보를 연결하기 위한 PC공동주택의 PC공법이 제공될 수 있다. According to one aspect of the present invention for achieving the above object, a PC method of a PC apartment building for connecting an RC wall and a PC beam using a connecting unit including a first step of installing an RC wall in which a first connecting unit is embedded so that an upward engaging plate portion is laterally exposed, a second step of manufacturing a PC beam in which a second connecting unit is embedded so that a downward engaging plate portion, which is assembled face to face with the upward engaging plate portion, is laterally exposed, a third step of assembling the PC beam so that a downward engaging plate portion of the second connecting unit is hung face to face with the upward engaging plate portion of the first connecting unit to support a gravity direction load of the PC beam, and a fourth step of pouring topping concrete on top of the PC beam can be provided.
여기서 상기 제1연결유닛은 RC벽체 내부에 매립되는 제1브라켓과, 상기 제1브라켓에 일단이 결합되고 타단이 RC벽체 측방향으로 “ㄴ”자 형태로 절곡 노출되는 상향 걸림판부로 이루어질 수 있다.Here, the first connecting unit may be formed of a first bracket embedded in the RC wall, and an upward hanging plate portion having one end joined to the first bracket and the other end bent and exposed in an “L” shape in the lateral direction of the RC wall.
이때, 상기 제2연결유닛은 PC보 내부에 매립되는 제2브라켓과, 상기 제2브라켓에 일단이 결합되고 타단이 보 하부근과 용접 연결되는 연결근과, 상기 제2브라켓에 일면이 결합되고 하측으로 연장되어 상향 걸림판부와 대면 접촉하도록 된 하향 걸림판부로 이루어질 수 있다.At this time, the second connecting unit may be composed of a second bracket embedded inside the PC, a connecting member having one end joined to the second bracket and the other end welded to the lower part of the member, and a downward engaging plate portion having one side joined to the second bracket and extended downward to make direct contact with the upward engaging plate portion.
이상에서와 같은 본 발명은 보와 기둥의 공사 중 접합을 견고히 함으로써 수평하중에 효율적으로 지지하게 되어 조립 시 중량의 프리캐스트 보가 탈락함에 의한 건축 구조물의 연속붕괴를 방지하고, 외부 골조벽체가 없는 라멘구조의 특징 및 고층화되는 공동주택의 고소작업 시, 측면이나 하부 작업 없이 상부에서의 간단한 연결작업만으로 접합을 구성하여 작업자의 시공 중 안전성을 확보할 수 있는 효과를 갖는다.As described above, the present invention effectively supports horizontal loads by reinforcing joints between beams and columns during construction, thereby preventing continuous collapse of building structures due to detachment of heavy precast beams during assembly, and has the effect of ensuring safety for workers during construction by forming joints only with simple connecting work from the top without side or bottom work during high-rise construction work in a frame structure without external skeletal walls.
또한, 본 발명은 RC벽체와 PC보 사이에 돌출되는 부분이 없도록 하여 건축물의 층고를 확보하여 사용성 및 경제성을 크게 향상시킬 수 있으며, 건축물의 층고 확보를 통하여 주거시설의 높은 품질을 제공하는 효과를 갖는다.In addition, the present invention can greatly improve usability and economy by ensuring the floor height of a building without any protruding portion between the RC wall and the PC beam, and has the effect of providing high quality of residential facilities by ensuring the floor height of the building.

FIG. 2 is a cross-sectional view of a PC assembly explaining a PC method of a PC apartment according to an embodiment of the present invention, and FIG. 3 is a perspective view illustrating a second connection unit according to an embodiment of the present invention.
도 2를 참조하면, 본 발명의 일실시예에 따른 연결유닛을 이용하여 RC벽체와 PC보를 연결하기 위한 PC공동주택의 PC공법은 크게 RC벽체(140)를 설치하는 1단계; PC보(120)를 제조하는 2단계; RC벽체(140)와 PC보(120)를 조립하는 3단계; PC보 상부에 토핑 콘크리트(190)를 타설하는 4단계;를 포함한다.Referring to FIG. 2, the PC method of a PC apartment building for connecting an RC wall and a PC beam using a connecting unit according to one embodiment of the present invention largely includes a first step of installing an RC wall (140); a second step of manufacturing a PC beam (120); a third step of assembling the RC wall (140) and the PC beam (120); and a fourth step of pouring topping concrete (190) on top of the PC beam.
먼저, 도 2에서 보는 바와 같은 RC벽체(140)를 설치한다. 이때, 상기 RC벽체(140)의 설치과정에서 상향 걸림판부(153)가 측방향에 노출되도록 제1연결유닛(150)이 매립되어 시공된다.First, as shown in Fig. 2, an RC wall (140) is installed. At this time, during the installation process of the RC wall (140), the first connecting unit (150) is embedded and constructed so that the upward hanging plate portion (153) is exposed in the lateral direction.
이때, 상기 제1연결유닛(150)은, RC벽체(140) 내부에 매립되는 제1브라켓(151)과, 상기 제1브라켓(151)에 일단이 결합되고 타단이 RC벽체(140) 측방향으로 “ㄴ”자 형태로 절곡 노출되는 상향 걸림판부(153)로 이루어질 수 있다.At this time, the first connection unit (150) may be composed of a first bracket (151) embedded in the RC wall (140) and an upward hanging plate (153) having one end joined to the first bracket (151) and the other end bent and exposed in an “L” shape in the lateral direction of the RC wall (140).
이때, 상기 제1브라켓(151)은 금속판재 형태로 제작되며, RC벽체(140) 외면과 동일 평면이 되도록 매립되도록 하고, 상기 매립측 이면에는 복수의 스터드볼트(B)들을 매립방향으로 연장 형성하여 고정력이 향상되도록 할 수 있다.At this time, the first bracket (151) is manufactured in the form of a metal plate and is embedded so as to be flush with the outer surface of the RC wall (140), and a plurality of stud bolts (B) are formed to extend in the embedded direction on the back surface of the embedded side so as to enhance the fixing force.
이때, 상기 제1브라켓(151)의 전면에 결합되는 상향 걸림판부(153)는 용접에 의해 결합될 수도 있으나, 착탈 가능하게 볼트조립방식에 의해 결합되도록 할 수도 있다.At this time, the upward hanging plate part (153) coupled to the front of the first bracket (151) may be coupled by welding, but may also be coupled by a bolt assembly method so that it can be detachably attached.
그리고, 도 2에서 보는 바와 같은 PC보(120)를 제조한다.And, as shown in Fig. 2, a PC board (120) is manufactured.
상기 PC보(120)는 지상에서 몰드를 이용해 제작된 후, 크레인으로 인양하여 PC기둥(110) 상부에 조립되도록 한다.The above PC beam (120) is manufactured using a mold on the ground, then lifted by a crane and assembled on top of the PC pillar (110).
이때, 상기 PC보(120)의 수평방향 단부에는 상향 걸림판부(153)와 대면 조립되는 하향 걸림판부(165)가 측방향에 노출되는 제2연결유닛(160)이 매립되도록 시공될 수 있다.At this time, a second connection unit (160) can be constructed so that a downward engaging plate part (165) that is assembled facing the upward engaging plate part (153) is exposed laterally at the horizontal end of the PC board (120).
상기 제2연결유닛(160)은, 도 3에서 보는 바와 같이 PC보(120) 내부에 매립되는 제2브라켓(161)과, 상기 제2브라켓(161)에 일단이 결합되고 타단이 보 하부근(123)과 용접 연결되는 보 하부 연결근(163)과, 상기 제2브라켓(161)에 일면이 결합되고 하측으로 연장되어 상향 걸림판부(153)와 대면 접촉하도록 된 하향 걸림판부(165)로 이루어질 수 있다.The second connecting unit (160) may be composed of a second bracket (161) embedded in the PC beam (120) as shown in FIG. 3, a lower beam connecting member (163) having one end joined to the second bracket (161) and the other end welded to the lower beam member (123), and a downward engaging plate member (165) having one end joined to the second bracket (161) and extending downward to come into contact with the upward engaging plate member (153).
이때, 상기 제2브라켓(161)은 수평방향으로 설치되는 상판(161a)과, 상기 상판(161a)의 저면에 수직하게 세워지는 복수의 수직판(161b)으로 구성될 수 있다.At this time, the second bracket (161) may be composed of a top plate (161a) installed horizontally and a plurality of vertical plates (161b) erected vertically on the lower surface of the top plate (161a).
도 3을 참조하면, 제2브라켓(161)의 형태는 정면에서 보았을 때, “ㅠ”형태로 제작될 수 있다.Referring to Fig. 3, the shape of the second bracket (161) can be manufactured in a “ㅠ” shape when viewed from the front.
이때, 상기 상판(161a)과 수직판(161b)에는 고정력 향상을 위한 스터드볼트(B)들이 더 형성될 수 있다.At this time, stud bolts (B) may be further formed on the upper plate (161a) and vertical plate (161b) to improve fixing strength.
그리고, 상기 하향 걸림판부(165)는 상판(161a) 및 수직판(161b)의 후방에서 결합되도록 하되, 상단이 상판(161a)의 저면에 결합되고, 전면이 수직판(161b)들과 결합되어 상판(161a) 및 수직판(161b)의 결합구조를 견고하게 하는 한편, 수직판(161b)보다 하측으로 더 연장시킨 연장부를 이용해 제1브라켓의 상향 걸림판부(153)와 수직방향으로 대면 접촉하여 끼움결합하게 된다.And, the downward hooking plate part (165) is coupled to the rear of the upper plate (161a) and the vertical plate (161b), with the upper end being coupled to the lower surface of the upper plate (161a) and the front end being coupled to the vertical plates (161b), thereby reinforcing the coupling structure of the upper plate (161a) and the vertical plate (161b), and using an extension part that is extended downward further than the vertical plate (161b), it comes into vertical contact with the upward hooking plate part (153) of the first bracket and is fitted into it.
예컨대, 제1연결유닛(150)의 상향 걸림판부(153)에 오차흡수가 가능하도록 제2연결유닛(160)의 하향 걸림판부(165)가 대면하도록 걸쳐지고, PC보(120)의 중력방향 하중이 지지되도록 조립된다. For example, the downward engaging plate (165) of the second connecting unit (160) is hung so as to face the upward engaging plate (153) of the first connecting unit (150) so as to allow error absorption, and is assembled so that the gravity load of the PC board (120) is supported.
이후, PC보 상부에 토핑 콘크리트(190)를 타설하도록 한다.Afterwards, topping concrete (190) is poured on top of the PC board.
이상 살펴본 바와 같은 본 발명은 보와 기둥의 공사 중 접합을 견고히 함으로써 수평하중에 효율적으로 지지하게 되어 조립 시 중량의 프리캐스트 보가 탈락함에 의한 건축 구조물의 연속붕괴를 방지하고, 외부 골조벽체가 없는 라멘구조의 특징 및 고층화되는 공동주택의 고소작업 시, 측면이나 하부 작업 없이 상부에서의 간단한 작업만으로 접합을 구성하여 작업자의 시공 중 안전성을 확보할 수 있고, 조립부를 수평화하여, 공동주택의 천장 마감에 돌출되는 부분이 없도록 하고 제작시부터 조립부의 오차흡수가 가능하도록 정밀도를 확보하여 주거시설의 높은 품질을 제공할 수 있게 된다.As described above, the present invention effectively supports horizontal loads by reinforcing joints between beams and columns during construction, thereby preventing continuous collapse of building structures due to detachment of heavy precast beams during assembly, and, in the case of high-rise apartment buildings, by forming joints with simple work from the top without side or bottom work due to the characteristics of a frame structure without an external skeletal wall, without the side or bottom work during high-rise apartment building construction, thereby ensuring safety of workers during construction, and by horizontalizing the assembly part so that there is no protruding part in the ceiling finish of the apartment building, and by securing precision so that errors in the assembly part can be absorbed from the time of manufacturing, thereby providing high quality residential facilities.
이상에서와 같이 본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.As described above, the present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims, and such modifications are within the scope of the claims.
