[산업상 이용분야][Industrial use]
본 발명은 보의 외측변에 거푸집을 설치하지 아니하고도 미경화콘트리트를 타설하여 보와 슬라브층을 일체로 성형시킬 수 있게 함으로써 공사를 보다 간편하고 신속하게 진행시킬 수 있는 PC보 및 그를 이용한 수평구조체의 시공방법에 관한 것이다.The present invention provides a PC beam and a horizontal structure using the PC beam that can be carried out more easily and quickly by placing the uncured concrete to form the beam and the slab layer integrally without installing a formwork on the outer side of the beam. It relates to the construction method of the.
[종래기술][Private Technology]
종래의 PC보는 제1도에서 도시되는 바와 같이, 단면형상이 사각형으로 형성되며 길이방향으로 길게 형성되는 몸체부(2)와, 상기 몸체부(2)의 상면에 노출되는 노출철근(3)으로 구성되었다.As shown in FIG. 1, a conventional PC beam includes a body portion 2 having a cross-sectional shape formed in a quadrangle and extending in the longitudinal direction, and an exposed rebar 3 exposed on an upper surface of the body portion 2. Configured.
이와 같이, 구성되는 종래의 것은 제2도에서 도시되는 바와 같이, 기둥상면에 설치된 사각형 단면의 PC보(1)와 PC보(1')사이에 상기 PC보(1)(1')의 내측 상단부에 PC슬라브(4)가 올려지도록 설치한 후, 상기 PC보(1)(1')의 외측변에 측면거푸집(5)이 밀착되게 설치하고, 상기 PC보(1)(1') 및 PC슬라브(4) 상호간에 노출된 노출철근(3)들을 연결한 후, 미경화콘크리트(6)를 현장하게 일체로 타설하여 슬라브층을 성형시킨 후에 상기 측면거푸집(5)을 해제함으로써 수평구조체를 완성시켰다.In this way, the conventional one constructed as shown in FIG. 2 has an inner side of the PC beam 1 and 1 'between the PC beam 1 and the PC beam 1' having a rectangular cross section provided on the columnar surface. After installing the PC slab 4 to the upper end, the side formwork 5 is installed in close contact with the outer side of the PC beam (1) (1 '), and the PC beam (1) (1') and After connecting the exposed steel bars 3 exposed to the PC slabs 4, the uncured concrete 6 is cast in one piece to form a slab layer, and then the horizontal formwork 5 is released to release the horizontal structure. It was completed.
[종래기술의 문제점][Problems with Prior Art]
그런데, 상기한 바와 같이, 종래의 것은 PC보가 단면상 4각형으로 형성되면서 그 상면에 노출철근(3)을 제외하고는 평활면으로 형성되는 것이기 때문에 측면거푸집(5)을 설치하지 않으면 슬라브층 성형을 위한 미경화콘크리트(6) 타설시 미경화콘크리트가 PC보(1)의 외측변으로 흘러나가게 된다.However, as described above, since the PC beam is formed in a quadrangular shape on the cross-section, except that the exposed reinforcing bar 3 is formed on the upper surface thereof, the slab layer is formed without the side formwork 5. When placing uncured concrete 6, uncured concrete flows out to the outer side of the PC beam 1.
따라서, 종래의 PC보로 수평구조체를 시공할 때에는 미경화콘크리트의 흘러나감을 방지하기 위해 거푸집이 반드시 필요하게 됨으로써, 첫째, PC보의 외측변에 측면거푸집(5)을 설치하는 거푸집설치작업 및 미경화콘크리트 경화후 거푸집을 해체하는 거푸집해체작업이 필연적으로 수반됨으로써 설치 및 해체에 따른 인력이 소요되고, 또한 전체적인 공사기간이 길어지는 문제점이 있으며, 둘째, 거푸집설치 및 해체작업에 소요되는 인건비 뿐만 아니라, 거푸집을 설치하기 위해서 거푸집을 구입 및 운반하는 과정에서 초래되는 자재구입비 및 운반비 등의 공사비가 증대되는 문제점이 있고, 셋째, 작업현장내에 거푸집이 반입됨으로써 이를 적재사용하는 공간이 필요하게 되어 작업공간이 협소해지고, 또한 작업현장을 청결하게 유지하는 어려움 등의 문제점이 있었다.Therefore, when constructing a horizontal structure with a conventional PC beam, formwork is absolutely necessary to prevent the uncured concrete from flowing out. First, the formwork installation work for installing the side formwork 5 on the outer side of the PC beam and As the form dismantling work for dismantling formwork after hardening concrete is inevitably involved, manpower is required for installation and dismantling, and there is a problem that the overall construction period is long. Second, labor costs not only for the form installation and dismantling work but also There is a problem in that construction costs such as material purchase costs and transportation costs incurred in the process of purchasing and transporting formwork are increased to install the formwork. Third, since the formwork is brought into the work site, a space for loading and using the formwork is required. Problems such as narrowing and difficulty keeping the workplace clean It was dots.
[발명의 목적][Purpose of invention]
따라서, 본 발명은 건출물의 수평구조체 시공시 PC보와 PC슬라브를 접합시켜 거푸집이 전혀 필요없는 PC공법을 통하여 수평구조체를 일체로 시공함으로써, 첫째, 보와 슬라브층 성형시 측면거푸집을 설치하지 아니하고도 미경화콘크리트를 타설할 수 있도록 함으로써 공사기간을 대폭적으로 단축시킬 수 있으며, 둘째, 거푸집을 설치하지 아니함으로써 거푸집설치 및 해체에 따른 인력이 소요되지 않게 되어 인건비. 자재구입비 및 운반비 등의 공사비를 절감할 수 있으며, 셋째, 거푸집을 설치하지 아니함으로써 적재공간등이 불필요함으로 그만큼 작업공간을 활용할 수 있고, 또한 작업현장을 항시 청결하게 유지할 수 있도록 하는 PC보 및 그를 이용한 수평구조체의 시공방법을 제공하는데 있다.Therefore, in the present invention, by constructing the horizontal structure integrally through the PC method that requires no formwork by joining the PC beam and PC slab at the time of construction of the horizontal structure of the building, first, without forming the side formwork when forming the beam and slab layer The construction period can be drastically shortened by allowing the unhardened concrete to be poured. Second, labor costs are eliminated because no manpower is required to install and dismantle the formwork. The construction cost such as material purchase cost and transportation cost can be reduced. Third, PC beam and him that can make use of the work space as there is no need for loading space by installing no formwork and also keep the work site clean at all times. It is to provide a construction method of the horizontal structure used.

따라서, 본 발명은 PC보의 외측상부에 형성된 돌출턱(12)이 거푸집역할을 수행하게 됨으로써 별도의 거푸집판넬을 설치할 필요가 없게 되며, 이에 따라 거푸집 설치작업 및 해체작업이 생략됨으로 공사기간을 대폭적으로 단축할 수 있으며, 또한 공사비를 크게 절감시킬 수 있는 것이다.Therefore, the present invention does not need to install a separate formwork panel by the protrusion jaw 12 formed on the outer upper portion of the PC beam, thereby eliminating the formwork and dismantling work, thereby significantly reducing the construction period. It can be shortened and the construction cost can be greatly reduced.
[발명의 효과][Effects of the Invention]
이와 같이, 본 발명은 건축물의 PC보와 PC슬라브를 접합시키는 수평구조체 시공시, PC보 사이에 시공되는 슬라브층의 두께와 동일한 길이를 갖는 돌출턱(12)이 상부로 돌출 형성되어 거푸집이 전혀 필요없는 PC공법을 통하여 수평구조체를 일체로 시공함으로써, 첫째, 보와 슬라브층 성형시 측면거푸집을 설치하지 아니하고도 미경화콘크리트를 타설할 수 있도록 함으로써 공사기간을 대폭적으로 단축시킬 수 있으며, 둘째, 거푸집을 설치하지 아니함으로써 거푸집설치 및 해체에 따른 인력이 소요되지 않게 되어 인건비·자재구입비 및 운반비 등의 공사비를 절감할 수 있으며, 셋째, 거푸집을 설치하지 아니함으로써 적재공간등이 불필요함으로 그만큼 작업공간을 활용할 수 있고, 또한 작업현장을 항시 청결하게 유지할 수 있는 효과가 있다.Thus, in the present invention, when constructing a horizontal structure for joining the PC beam and PC slab of the building, the projection jaw (12) having the same length as the thickness of the slab layer constructed between the PC beam is formed to protrude upwards at all By constructing the horizontal structure integrally through the PC method, which is not necessary, firstly, the construction period can be drastically shortened by allowing the uncured concrete to be cast without installing the side formwork when forming the beam and slab layers. By not installing the formwork, no manpower is required due to the formwork installation and dismantling, thus reducing the construction cost such as labor cost, material purchase cost, and transportation cost. Third, there is no need to install the formwork. It also has the effect of keeping the workplace clean at all times.
이상에서 살펴본 바와 같이, 본 발명은 PC보의 외측상부에 형성된 돌출턱이 슬라브층 성형을 위한 미경화콘크리트 타설시 미경화콘크리트가 외부로 흘러나감을 방지하는 거푸집판넬의 역할을 수행하므로 거푸집이 불필요하며, 또한 거푸집설치 및 해체작업에 따른 시간만큼 전체적인 공사기간을 단축할 수 있으며, 한편 거푸집을 설치하지 아니함으로써, 인건비·자재구입비 및 운반비 등의 공사비를 절감할 수 있으며, 또한 작업공간의 여유와 작업현장을 항시 청결하게 유지하는데 도움이 되는 매우 유용한 발명이다.As described above, in the present invention, since the projection jaw formed on the outer upper portion of the PC beam serves as a formwork panel to prevent the uncured concrete from flowing out when the uncured concrete is poured for forming the slab layer, no formwork is required. In addition, the overall construction period can be shortened by the time according to the formwork installation and dismantling work, and by not installing the formwork, the construction cost such as labor cost, material purchase cost and transport cost can be reduced, It is a very useful invention that helps keep the workplace clean at all times.
