2일에 한개 층씩 올라가는 콘크리트 구조체 공사방법{2-day-cycle concrete structure construction method}2-day-cycle concrete structure construction method

본 발명은 철근콘크리트구조 건물의 공사방법에 관한 것이다. 더 상세하게는 철근콘크리트공사 기간을 대폭 줄일 수 있는 공사방법이다.
The present invention relates to a method of constructing a reinforced concrete structure building. More specifically, it is a construction method capable of drastically reducing the period of construction of reinforced concrete.

철근콘크리트구조로 설계한 건물을 지으려면 먹메김, 기둥철근과 거푸집 설치, 동바리와 상부층 슬래브 거푸집과 철근을 조립하고 설치한 뒤 콘크리트를 붓고, 구조체로써 강도를 발현할 때까지 일정기간 양생을 거쳐 한개 층 공사가 완료된다. 콘크리트공사는 공정도 복합되고, 콘크리트를 양생하는 데 일정 기간이 필요하기 때문에 시간이 오래 걸려 한개 층 공사에 보통 7일~10일 소요된다. 건축물의 완공 시기는 건축주에게 중요한 관심사이다. 건물을 빨리 준공하면 건축물을 사용할 수 있는 시기가 앞당기고, 건설비에 투자한 비용을 더 빨리 걷어 들일 수 있기에 공사 기간을 줄일 수 있는 방안을 요구한다. In order to build a building with reinforced concrete structure, it is necessary to pour concrete, install reinforcing bars and formwork, assemble copper bar and upper slab formwork and reinforcement, pour concrete, and cure it for a certain period of time until strength is expressed as a structure. Floor construction is complete. The concrete construction process is complex and requires a certain period of time to cure concrete, which takes a long time and usually takes 7 to 10 days to construct a single floor. Completion time of the building is an important concern to the client. Completion of the building quickly will lead to a faster time to use the building, and will allow for a faster retrieval of the investment in construction costs.

이런 요구에 응하여 기술자들은 작업구획 나누기, 작업조 짜기, 작업 시간 연장 등 여러 방안을 찾았지만 한 층을 올리는데 개략 7~10일이 걸렸으며, 보통 업계에서는 한개 층 평균 공기의 한계는 5일로 인식되어 왔다.
In response to these demands, the technicians found several options, such as dividing the work area, weaving work, and extending the working time, but it took approximately 7 to 10 days to raise one floor, and the industry generally recognized the limit of one floor average air as 5 days. come.

본 발명은 종래 콘크리트공사에서 있던 여러 문제점을 해소하기 위한 것이다.The present invention is intended to solve various problems in conventional concrete constructions.

첫째, 본 발명은 철근콘크리트구조에서 한개 층 공사기간을 평균 이틀로 줄일 수 있는 방법을 개발하는 것이다.First, the present invention is to develop a method that can reduce the construction period of one floor in the reinforced concrete structure to an average of two days.

둘째, 본 발명은 한개 층 공사기간을 대폭 줄임으로써 인력과 장비를 효율성 있게 활용하는 방법을 개발하는 것이다.Second, the present invention is to develop a method of efficiently utilizing manpower and equipment by significantly reducing the construction period of one floor.

셋째, 본 발명은 한개 층 공사기간을 대폭 줄임으로써 전체 공사기간을 줄여 건축주가 더욱 빨리 건물을 사용할 수 있게 하는 방법을 개발하는 것이다.
Third, the present invention is to reduce the overall construction period by significantly reducing the construction period of one floor to develop a method that allows the owner to use the building more quickly.

위 과제를 해결하기 위해 본 발명은, 기준 층 바닥을 여러 개 작업 구획으로 나누고, 한쪽 구획에서부터 콘크리트 슬래브 바닥에 먹메김, 기둥철근 설치, 기둥 거푸집 설치, 벽체 거푸집 설치, 동바리 설치, 상부층 바닥을 만들기 위한 슬래브 거푸집과 철근을 설치한 뒤 작업이 완료된 구획부터 콘크리트를 타설하고, 다음 상부층으로 넘어가는 공사로서, 상기 콘크리트를 설계기준강도보다 25%이상 더 강도가 높은 콘크리트를 사용하여 초기에 강도가 빨리 나타나게 하고, 공사에 필요한 각 공정간 작업요소와 소요되는 시간을 최대한 압축하여 한개 층의 공사기간을 크게 줄일 수 있다. In order to solve the above problems, the present invention divides the reference floor floor into a number of work compartments, from one compartment to the concrete slab floors, pillar reinforcement installation, column formwork installation, wall formwork installation, copper bar installation, making the upper floor floor After installing the slab formwork and reinforcing bars for the concrete, the concrete is poured from the completed block and then transferred to the next upper floor. The construction period of one floor can be greatly reduced by compressing the work elements and the time required for each process.

또한, 효과를 더 높이기 위해 바닥은 평슬래브(Flat Plate Slab)구조로 설계한다. 나아가 위 동바리는 조립식을 사용하고, 콘크리트의 초기 강도가 0.5Mpa 이상이면 위층 바닥의 먹매김 작업에 들어간다. 그리고 콘크리트 강도가 14Mpa 이상이거나, 설계기준강도의 2/3이상이 발현되면 슬래브 거푸집을 해체함으로써 한 층을 공사하는 시간을 줄인다.
In addition, the floor is designed with a flat plate slab structure to further enhance the effect. Furthermore, the upper clubs use a prefabricated type, and when the initial strength of concrete is 0.5Mpa or more, it enters the feeding operation of the upper floor. And if the concrete strength is more than 14Mpa or more than 2/3 of the design standard strength, the slab formwork is dismantled to reduce the time to construct a floor.

본 발명은 철근콘크리트구조에서 한개 층 공사기간을 평균 이틀로 줄임으로써 인력과 장비를 효율성 있게 활용할 수 있다. 그리고 한개 층 공사기간을 대폭 줄임으로써 전체 공사기간을 줄여 건축주가 더욱 빨리 건물을 사용할 수 한다.
The present invention can efficiently utilize manpower and equipment by reducing the construction period of one floor in the reinforced concrete structure to an average of two days. By drastically shortening the construction period of one floor, the construction period can be shortened so that the owner can use the building more quickly.

본 발명을 상세하게 설명한다.The present invention will be described in detail.

콘크리트 골조공사에는 거푸집 설치, 철근 배근, 콘크리트 타설, 양생, 거푸집 해체 등 일련으로 여러 공정이 진행된다. 일정 품질을 확보하면서 공기를 줄이려면 작업을 빨리 하기 위해 인력을 많이 투입하는 것을 맨 먼저 고려한다. 그러나 아무리 인력을 많이 투입하더라도 콘크리트공사에는 절대 공기가 있어 줄일 수 있는 한계가 있다. 즉 콘크리트의 품질을 확보하기 위해서는 콘크리트 양생기간, 거푸집 존치기간 등을 지켜야 한다. 이들 조건을 만족할 때까지 그 다음 작업을 진행할 수 없다.Concrete frame construction involves a series of processes such as formwork, reinforcement, concrete pouring, curing, and demolishing formwork. To reduce the air while ensuring a constant quality, the first thing to consider is to put a lot of manpower in order to speed up the work. However, no matter how much manpower is applied, there is a limit to reduce the amount of concrete in construction. In other words, to ensure the quality of concrete, concrete curing period and the duration of the formwork must be maintained. The next task can not be performed until these conditions are satisfied.

기준층(N층) 바닥을 5개의 작업구획으로 나누고, 나눈 구획의 한쪽 구획에서부터 콘크리트 슬래브 바닥에 먹메김, 기둥철근 설치, 기둥 거푸집 설치, 벽체 거푸집 설치, 동바리 설치, 상부층 바닥을 만들기 위한 슬래브 거푸집과 철근을 설치한 뒤 작업이 완료된 구획부터 콘크리트를 타설하고, 기준층에서 그 상부층(N+1층)으로 올라가면서 공사한다.The floor of the reference layer (N-layer) is divided into five work compartments, and from one side of the divided section to the bottom of the concrete slab, there is a slab die for installing the column, reinforcing the column, installing the column formwork, After installing the reinforcing bars, pour the concrete from the compartment where the work is completed, and build it up from the reference layer to the upper layer (N + 1 layer).

구간은 기준층 바닥을 보통 5개 정도로 구획하지만 5개에 한정되는 것은 아니다. 바닥이 넓다면 5개 이상 더 나눌 수 있다. 보통은 5개 구간이면 무난하다고 본다.The segment covers the floor of the reference layer generally to about five but is not limited to five. If the floor is wide, you can divide more than five. Normally, it is considered to be acceptable if it is five segments.

거푸집 해체 시기는 전체 공기에 영향을 준다. 보통 거푸집 존치기간은 기온별(10~20℃) 시멘트 종류에 따라 통상 7일을 존치해야 한다. 압축강도를 기준을 삼으면 설계기준강도의 2/3 이상이면 거푸집을 해체해도 된다. The mold demolition time affects the entire air. Usually, the duration of the formwork is normally 7 days depending on the temperature (10 ~ 20 ℃) cement type. Based on compressive strength, formwork may be dismantled if it is at least two-thirds of the design reference strength.

거푸집을 빨리 해체하기 위해서는 콘크리트 초기 강도를 빨리 나오도록 해야 한다. 그래서 콘크리트에 조강혼화제를 넣어 초기강도를 빨리 발현시켜 각 공정에 소요되는 시간을 줄일 수 있게 한다.In order to dismantle the form quickly, the initial strength of the concrete should be brought out quickly. Therefore, it is possible to reduce the time required for each process by expressing the initial strength quickly by adding crude admixture to concrete.

콘크리트 초기강도가 빨리 나오도록 하기 위해 조강제를 쓰기도 하지만, 콘크리트 설계기준강도보다 더 높은 강도를 가진 콘크리트를 사용하여 목적을 이룰 수 있다. 즉 콘크리트 배합강도가 높을수록 초기 강도가 빨리 발현되는 것을 이용하는 것이다. 실제 콘크리트의 설계기준강도 27MPa이더라도 적용하는 콘크리트 강도를 35MPa인 것을 사용했더니 초기 강도가 더 빨리 나왔다.It is possible to achieve the purpose by using concrete with higher strength than the strength of the concrete design standard, although it is used as a roughing agent to make the early strength of the concrete come out quickly. That is, the higher the concrete mixing strength is, the faster the initial strength is expressed. Even when the actual reference strength of the concrete is 27 MPa, the concrete strength of the applied concrete is 35 MPa, and the initial strength is faster.

실제 사례에서 보면, 콘크리트 타설 뒤 5~7시간 경과되어 콘크리트 강도가 0.3 ~ 0.6MPa일 때 상부층 바닥에 먹매김 작업을 시작하고, 콘크리트 타설 뒤 11~14시간 경과되어 상기 콘크리트 강도가 4.6 ~ 6.6MPa이면 상부층 바닥에 자재 올리기 등 작업을 시작하고, 콘크리트 타설 뒤 24시간이 경과하여 상기 콘크리트의 강도가 14MPa 이상이거나, 설계기준강도의 3분의 2이상이면 기준층의 슬래브 거푸집을 해체한다.In the actual case, after 5-7 hours after the concrete is poured, when the concrete strength is 0.3 to 0.6 MPa, the filling operation starts at the bottom of the upper layer, and after 11 to 14 hours after the concrete is poured, the concrete strength is 4.6 to 6.6 MPa. The work starts to raise the material on the bottom of the upper layer, and 24 hours after the concrete is placed, the slab formwork of the reference layer is dismantled if the strength of the concrete is 14 MPa or more, or more than two thirds of the design reference strength.

작업시간을 줄이기 위해 동바리 또는 거푸집 자재는 조립식 자재를 사용하여 현장 작업시간을 줄일 수 있다.In order to reduce the working time, the dough or formwork can use prefabricated materials to reduce field work time.

본 발명에 대한 기준층 작업을 5개 작업 구간으로 나눴을 때 작업 내용을 단계별로 설명한다.When the reference layer work according to the present invention is divided into five work sections, the work content will be described step by step.

(1)단계: 첫째 날 8시에 기준층(N층)의 하부층(N-1층)에서 해체한 거푸집 자재를 N층 바닥에 올리고, N층의 기둥 철근 조립과 외벽 벽체 대형거푸집을 설치하기 시작한다.Step (1): At 8:00 on the first day, formwork material dismantled from the lower layer (N-1 layer) of the reference layer (N layer) is placed on the floor of the N layer, and the N-layer column reinforcement assembly and external wall wall formwork are started. do.

(2)단계: 첫째 날 10시~12시에 N층의 기둥 철근과 거푸집 설치를 완료하고, 그 상부층(N+1층) 1구간에 슬래브 거푸집을 설치한다.Step (2): On the first day, at 10 to 12 o'clock, complete the installation of column reinforcement and formwork on the N floor, and install the slab formwork on the first section of the upper layer (N + 1 floor).

(3)단계: 첫째 날 13시~15시에 N+1층의 2~3구간에 슬래브 거푸집 설치하고, 1구간 슬래브에 철근을 설치하고, N층의 벽체거푸집 설치를 시작한다.Step (3): At 13:00 to 15:00 on the first day, install slab formwork in sections 2-3 of the N + 1 floor, install reinforcing bars in the section 1 slab, and start installing wall formwork on the N floor.

(4)단계: 첫째 날 15시~18시에 N+1층 4구간 슬래브 거푸집 설치하고, 2구간 슬래브 철근을 설치하고, N층 벽체거푸집 설치를 완료한다.Step (4): At 15: 00-18: 00 on the first day, install four-slab slab of N + 1 floor, install slab rebar of two sections, and complete the installation of N-wall wall formwork.

(5)단계: 둘째 날 08시~10시 N+1층 5구간 슬래브 거푸집 설치하고, 3구간 슬래브 철근을 설치하고, N+1층의 1구간 콘크리트를 타설하기 시작한다.Step (5): From 08 o'clock to 10 o'clock on the second day, install the 5th section slab formwork on the N + 1 floor, install the 3rd section slab rebar, and start pouring the 1st section concrete on the N + 1 floor.

(6)단계: 둘째 날 10시~12시에 N+1층 4구간 슬래브 철근을 설치하고, N+1층의 2구간 콘크리트를 타설한다.Step (6): Slab rebar is installed on the 4th section of N + 1st floor at 10 ~ 12 o'clock on the second day, and 2nd section concrete of the N + 1st floor is placed.

(7)단계: 둘째 날 12시~15시에 N+1층 5구간 슬래브 철근을 설치하고, N+1층의 3구간 콘크리트를 타설하고, 오전에 타설된 슬래브 콘크리트 바닥의 경화상태가 발자국이 생기지 않는 상태 정도로 굳은 것을 확인한 후 N+2층을 위한 바닥 먹매김 작업에 들어간다.(7) Step: Install slab reinforcing bars on N + 1 floor 5 sections at 12 o'clock to 15:00 on the second day, cast 3 sections concrete on N + 1 floor, and harden the slab concrete floor in the morning. After confirming that it has hardened to a level that does not occur, the floor is fed to the N + 2 layer.

(8)단계: 둘째 날 15시~18시에 N+1층 4구간과 5구간에 콘크리트를 타설하여 2일에 한개 층씩 올라가는 콘크리트 구조체 공사방법에 대한 한 주기(Cycle)를 완료하고, 익일 아침 08:00까지 양생한 후 N+2층 작업은 상기 (1)단계 작업부터 되풀이하여 공사한다.(8) Step: Complete the cycle of concrete structure construction method that raises one floor every two days by placing concrete in the 4th and 5th sections of the N + 1st floor at 15: 00-18: 00 on the second day, and the next morning After curing until 08:00, work on N + 2 floor will be repeated from step (1) above.

이 공법에서 슬래브 및 건물의 수평적 변위에 대한 구조체 강도를 확보하려면 콘크리트 양생일수를 확보해야 한다. 따라서, 이 공법에서는 최상층을 제외한 하부 7개층을 슬래브 하부에 동바리로 지지하는 것이 원칙이다.In this method, the concrete curing period must be secured in order to secure the structural strength of the slab and the horizontal displacement of the building. Therefore, in this method, it is a principle that the lower seven layers excluding the uppermost layer are supported on the lower side of the slab.

즉 슬래브 거푸집을 받치는 동바리는 N+8층 바닥콘크리트를 타설했을 때, N+7층에서 N+4층까지 동바리 지지 소요수량 100%를 설치하고, N+3층에서 N층까지는 소요수량의 50% 정도를 유지하는 것이 좋다. 물론 이때에도 거푸집은 상기 기준층 바닥의 콘크리트 강도가 4.6 ~ 6.6 MPa일 때 해체해야 하고, 작업층 상부층의 바닥 먹매김은 상부층의 바닥 콘크리트 강도가 0.3 ~ 0.6 MPa일 때 들어가면 된다.That is, when the concrete supporting the slab form is installed, it is necessary to install 100% of the required amount of support from the N + 7th floor to the N + 4th floor when the N + 8th floor concrete is laid, %. Of course, the mold should be disassembled when the concrete strength at the floor of the reference layer is 4.6 ~ 6.6 MPa, and the flooring of the upper layer of the working floor should be entered when the bottom concrete strength of the upper layer is 0.3 ~ 0.6 MPa.

이렇게 공사한다면 종래 공법이 한 층에 5~7일 소요되던 것을 2일로 줄일 수 있다.In this way, it can be reduced to two days when the conventional method takes five to seven days on one floor.

본 발명의 효과를 더욱 높이기 위하여 추가로 몇 가지 고려할 사항이 있다. In order to further enhance the effect of the present invention, there are some additional considerations.

첫째, 바닥설계는 평슬래브(Flat Plate Slab)구조로 설계하면, 기둥이나 벽체 거푸집 설치에 필요한 시간을 줄일 수 있어 시간을 더욱 단축할 수 있다.First, if the floor design is designed with a flat plate slab structure, the time required to install a column or a wall formwork can be shortened, thereby further shortening the time.

둘째, 벽체 거푸집 설치에 들어가는 시간을 줄이기 위해 되도록 벽량을 줄여 설계하면 좋다.Second, it is recommended to reduce the amount of wall as much as possible in order to reduce the time to install the wall formwork.

그 외에도 기술요소는 아니지만 작업자가 전체 작업공정을 이해하고, 타 공정 작업자와 손발을 맞추기 위해서는 사전 교육이 꼭 필요하다. 나아가 감리자 등 현장 작업관리자가 이 발명을 확실히 이해하고 품질관리 및 안전관리에 대응해야 한다.In addition, it is not a technical element, but it is necessary to pre-train the worker in order to understand the entire work process and to keep up with other process workers. Furthermore, the field manager, such as the supervisor, must understand this invention and respond to quality control and safety management.

이렇게 작업하면, 철근콘크리트 공사 전체 공기는 50~60%가 줄어든다. 이에 따라 현장관리비와 본사 관리비 등 간접 공사비가 대폭 절감될 수 있으며, 현장 작업자(형틀공, 철근공, 콘크리트공 등)의 생산성은 크게 높아질 수 있다. 또한, 건축주(사업주)는 건물을 빨리 인수받아 수익사업을 할 수 있다.By doing this, the total air of the reinforced concrete construction is reduced by 50 ~ 60%. As a result, indirect construction costs such as on-site maintenance costs and head office maintenance costs can be drastically reduced, and the productivity of field workers (molds, bars, concrete pits, etc.) In addition, the owner (employer) can acquire the building quickly and can do the profit business.

이하 본 발명의 보호범위를 청구항으로 구체화한다. 본 청구항은 발명의 구성요소의 일부 또는 전부를 단순 대체하거나 설계변경하는 것은 본 발명의 보호범위에 속하는 것으로 해설될 것이다.
Hereinafter, the protection scope of the present invention will be embodied in the claims. It is intended that the present invention cover only some of the components of the invention or the design modifications fall within the protection scope of the invention.
