Description

강콘크리트 합성보용 강재보 및 데크-빔 일체형 선조립 모듈Steel beam and deck-beam integrated pre-assembly module for steel concrete composite beam
본 발명은 강재보의 양 측면을 형성하는 것으로 기성 채널부재로 이루어진 제1, 2빔모듈 및 제1, 2빔모듈의 하부플랜지를 연결하는 하부플레이트로 구성되는 것으로, 자재 수급이 용이하고 별도의 가공 성형을 최소화하며 용접 공정을 생략할 수 있어 제작성과 경제성이 뛰어날 뿐 아니라 구조 성능이 우수한 강콘크리트 합성보용 강재보에 대한 것이다.The present invention forms both sides of a steel beam and consists of first and second beam modules made of ready-made channel members and a lower plate connecting the lower flanges of the first and second beam modules. It is about a steel beam for a composite steel beam with excellent structural performance as well as excellent manufacturability and economic feasibility by minimizing machining and forming and omitting the welding process.
철근콘크리트 공법 현장에서는 부재 형상에 맞게 거푸집을 설치하고 철근을 배근한 후 거푸집 내부에 콘크리트를 타설하여 구조물 부재를 시공한다. 이러한 재래식 철근콘크리트 공법은 노동 집약적이고, 품질 확보가 어려우며, 가설재 설치 및 해체 공정으로 인해 공기가 지연되는 단점이 있다. 뿐만 아니라 거푸집 지지를 위해 다수의 동바리가 필요하여 작업자 이동이 곤란하다.In the reinforced concrete construction site, the formwork is installed according to the member shape, the reinforcing bar is placed, and the concrete is poured inside the formwork to construct the structural member. This conventional reinforced concrete construction method has disadvantages in that it is labor intensive, it is difficult to secure quality, and the construction period is delayed due to the temporary installation and dismantling process. In addition, it is difficult to move the worker because a large number of rods are required to support the formwork.
이에 종래 재래식 철근콘크리트 공법을 대체하여 프리캐스트 콘크리트 공법(PC 공법)의 적용이 증가하고 있다.Accordingly, the application of the precast concrete method (PC method) is increasing to replace the conventional reinforced concrete method.
그러나 PC 공법은 자재 중량이 무거워 인양장비의 최대 중량을 초과하지 않도록 세분화된 양중계획이 필요하고, 주요 부재 설치 시 크레인 거치 시간이 많이 소요된다. 또한, 부재 제작 시간이 오래 걸려 원활한 공급이 어려울 수 있다.However, the PC method requires a detailed lifting plan so as not to exceed the maximum weight of the lifting equipment due to the heavy material weight, and it takes a lot of time to install the crane when installing the main members. In addition, it may take a long time to manufacture the member, so it may be difficult to supply it smoothly.
따라서 최근에는 가설 거푸집 대신 강재를 영구거푸집으로 사용하는 강콘크리트 합성 구조를 적용하는 사례가 늘어나고 있다. Therefore, in recent years, the number of cases of applying steel concrete composite structures using steel as permanent formwork instead of temporary formwork is increasing.
특히, 보 부재는 상부가 개방된 U자 형의 강재보를 설치하고, 강재보 내부에 콘크리트를 채우는 강콘크리트 합성보가 많이 사용된다. 상기 강재보는 영구거푸집의 역할을 할 뿐만 아니라 보의 주근 및 스터럽 역할을 하므로 내부의 철근 배근을 대폭 감소하거나 생략할 수 있다.In particular, for the beam member, a U-shaped steel beam with an open top is installed, and a steel-concrete composite beam that fills the inside of the steel beam with concrete is often used. The steel beam not only serves as a permanent formwork, but also serves as the main bar and stirrup of the beam, so that the internal reinforcement can be significantly reduced or omitted.
이러한 강콘크리트 합성 구조는 부재의 중량이 가벼워 양중 부담을 줄일 수 있고, 주요 부재 설치 시 크레인 거치 시간을 줄일 수 있으며, 접합부가 일체 타설되므로 접합부 균열이나 부재 파손 우려가 적다. 또한, 부재 제작 기간이 길지 않아 부재 공급이 원활하고, 제작 시 부재 크기나 형상 변화가 용이하다.Such a steel concrete composite structure can reduce the burden of lifting due to the light weight of the member, reduce the crane installation time when installing the main member, and reduce the risk of cracking or damage to the member because the joint is cast integrally. In addition, the member production period is not long, so the member supply is smooth, and the size or shape of the member can be easily changed during fabrication.
강콘크리트 합성보용 강재보는 주로 강판을 절곡하거나 용접하여 제작한다(등록특허 제10-1458508호, 제10-1456366호 등).Steel beams for steel concrete composite beams are mainly manufactured by bending or welding steel plates (Registration Patent Nos. 10-1458508, 10-1456366, etc.).
이 중 강판을 절곡하여 강재보를 제작하는 경우, 주로 두께가 얇은 강판을 냉간 압연에 의해 절곡한다. 이 방법은 원하는 치수로 자유롭게 부재를 제작할 수 있는 반면, 절곡 가능한 판 두께에 한계가 있다. 즉, 강판의 두께가 두꺼우면, 자재비 및 가공비가 많이 증가하여 경제성이 떨어진다.Among these, when a steel beam is manufactured by bending a steel plate, a thin steel plate is mainly bent by cold rolling. While this method can freely fabricate a member with desired dimensions, there is a limit to the thickness of the bendable plate. That is, if the thickness of the steel sheet is thick, the material cost and processing cost are greatly increased, and economical efficiency is deteriorated.
반대로 강판의 두께를 얇게 형성하면, 콘크리트 측압을 지지하기 위한 별도의 가설재가 필요하다. 그리고 휨 내력 부족으로 내부 철근 배근량을 늘리거나 철골보를 추가 배치하여야 하므로 시공성이 떨어진다.Conversely, if the thickness of the steel sheet is formed thin, a separate temporary material is required to support the concrete lateral pressure. Also, due to the lack of bending strength, it is necessary to increase the amount of internal reinforcement or to additionally place steel beams, so the workability is poor.
또한, 용접에 의해 제작되는 built-up 빔은 고가의 자동 용접 장비가 필요하고, 용접 시 강재의 소성 변형 우려가 있으며, 용접 품질 관리에 어려움이 따른다.In addition, the built-up beam produced by welding requires expensive automatic welding equipment, there is a risk of plastic deformation of steel during welding, and difficulty in welding quality control follows.
슬래브 역시 가설 거푸집 대신 영구거푸집인 데크플레이트를 사용하는 경우가 많다. 특히, 데크플레이트 상부에 트러스 거더가 구비된 트러스 데크는 별도의 가설 동바리 없이 설치할 수 있어 가설 공사를 최소화할 수 있고, 작업자 이동이 용이하다.For slabs, deck plates, which are permanent forms, are often used instead of temporary forms. In particular, the truss deck provided with the truss girder on the deck plate can be installed without a separate temporary support, so it is possible to minimize temporary construction and facilitate movement of workers.
한편, 종래 강합성보와 데크플레이트를 이용한 철근콘크리트 슬래브-보 구조물은 기둥 사이나 기둥 사이에 설치된 거더 사이에 강재보를 설치한 다음, 이웃하는 강재보 사이에 데크플레이트를 설치하고, 강재보 내부와 데크플레이트 상부에 콘크리트를 타설하여 시공한다. On the other hand, in the conventional reinforced concrete slab-beam structure using a steel composite beam and a deck plate, a steel beam is installed between columns or between girders installed between columns, and then a deck plate is installed between neighboring steel beams, and the inside of the steel beam and the deck Concrete is poured on top of the plate and constructed.
이때, 데크플레이트는 복수 매로 적층된 데크플레이트들을 강재보 상부에 적치하고, 각 데크플레이트들을 설치 위치에 판개한 후 강재보에 용접 등의 방법으로 고정하는 순서로 설치한다.At this time, the deck plate is installed in the order of placing the deck plates stacked in a plurality of sheets on top of the steel beam, selling each deck plate to the installation location, and then fixing it to the steel beam by a method such as welding.
그런데 이 경우 강재보와 데크플레이트는 각각 별도로 설치되는데다 개별 데크플레이트들을 판개하여야 하므로, 시공 시간이 많이 소요되는 단점이 있다. 아울러 데크플레이트의 판개 작업은 강재보 상부에서 고소 작업으로 수행되므로, 작업자 추락 등으로 인한 안전사고 우려가 있다.However, in this case, since the steel beam and the deck plate are installed separately, and the individual deck plates must be sold, there is a disadvantage that a lot of construction time is required. In addition, since the deck plate opening work is performed at a height above the steel beam, there is a risk of a safety accident due to a fall of the worker.
상기와 같은 문제점을 해결하기 위하여 본 발명은 자재 수급이 용이하고, 별도의 가공 성형을 최소화할 수 있으며, 용접 공정 생략으로 제작성과 경제성이 뛰어난 강콘크리트 합성보용 강재보를 제공하고자 한다.In order to solve the above problems, the present invention is to provide a steel beam for steel concrete composite beam that is easy to supply and demand materials, can minimize separate processing and molding, and has excellent manufacturability and economy by omitting the welding process.

도 1, 도 2 등에 도시된 바와 같이, 본 발명 강콘크리트 합성보용 강재보는 상부플랜지(51)와 하부플랜지(52) 및 상하부플랜지(51, 52)의 단부를 연결하는 웨브(53)로 구성되는 기성 채널부재(50)를 포함하여 구성되는 제1빔모듈(5); 상부플랜지(61)와 하부플랜지(62) 및 상하부플랜지(61, 62)의 단부를 연결하는 웨브(63)로 구성되는 기성 채널부재(60)를 포함하는 것으로, 상기 제1빔모듈(5)과 이격되도록 구비되는 제2빔모듈(6); 및 상기 제1빔모듈(5)의 채널부재(50)와 제2빔모듈(6)의 채널부재(60)의 하부플랜지(52, 62)를 상호 연결하는 하부플레이트(7); 로 구성되는 것을 특징으로 한다.As shown in Figs. 1 and 2, the present invention steel beam for composite steel beam consists of an upper flange 51, a lower flange 52, and a web 53 connecting the ends of the upper and lower flanges 51 and 52.

본 발명은 자재 수급이 용이하고, 별도의 가공 성형을 최소화하며, 용접 공정을 생략할 수 있어 제작성과 경제성이 뛰어날 뿐 아니라 구조 성능 또한 우수한 강콘크리트 합성보용 강재보를 제공하기 위한 것이다.An object of the present invention is to provide a steel beam for a steel concrete composite beam that is easy to supply and supply, minimizes separate processing and molding, and can omit a welding process, so that it is excellent in manufacturability and economy as well as structural performance.
본 발명은 좌우 한 쌍으로 구비되는 제1빔모듈(5)과 제2빔모듈(6), 상기 제1빔모듈(5)과 제2빔모듈(6)의 하부를 연결하는 하부플레이트(7)로 구성된다. The present invention provides a first beam module (5) and a second beam module (6) provided as a pair of left and right, and a lower plate (7) connecting the lower portions of the first beam module (5) and the second beam module (6) ) is composed of
상기 제1빔모듈(5)과 제2빔모듈(6)은 강재보(4)의 양 측면을 형성하는 것으로, 각각 채널부재(50, 60)를 포함하여 구성된다.The first beam module 5 and the second beam module 6 form both sides of the steel beam 4, and include channel members 50 and 60, respectively.
상기 제1빔모듈(5)을 구성하는 채널부재(50)는 상부플랜지(51)와 하부플랜지(52) 및 상하부플랜지(51, 52)의 단부를 연결하는 웨브(53)로 구성되어 ㄷ자형 단면으로 형성된다.The channel member 50 constituting the first beam module 5 is composed of an upper flange 51 and a lower flange 52 and a web 53 connecting the ends of the upper and lower flanges 51 and 52 to form a U-shape. formed in cross section.
마찬가지로 상기 제2빔모듈(6)을 구성하는 채널부재(60)는 상부플랜지(61)와 하부플랜지(62) 및 상하부플랜지(61, 62)의 단부를 연결하는 웨브(63)로 구성되어 ㄷ자형 단면으로 형성된다.Similarly, the channel member 60 constituting the second beam module 6 is composed of an upper flange 61, a lower flange 62, and a web 63 connecting the ends of the upper and lower flanges 61 and 62, and is composed of a U-shaped It is formed in a mold cross section.
상기 채널부재(50, 60)는 열간압연에 의해 생산되는 구조용 강재인 기성 형강재로, ㄷ형강이라고도 한다.The channel members 50 and 60 are ready-made section steels, which are structural steels produced by hot rolling, and are also referred to as U-beams.
기성 형강은 두께가 얇으면서도 단면 성능이 우수할 뿐 아니라 대량 생산되므로 자재비가 낮고, 자재 수급이 용이하다.The ready-made sections are thin and have excellent cross-sectional performance, and because they are mass-produced, material costs are low and material supply and demand are easy.
이에 강재보(4) 제작 시, ㄷ형 단면의 채널부재(50, 60)를 별도의 가공 없이 바로 사용할 수 있으므로, 용접 공정 없이 제작할 수 있고, 가공비와 가공 시간을 크게 절감할 수 있어 경제적이다.Therefore, when manufacturing the steel beam 4, since the channel members 50 and 60 of the C-shaped section can be used immediately without additional processing, it can be manufactured without a welding process, and it is economical because processing cost and processing time can be greatly reduced.
더욱이 주문 길이 생산 체제로 공급되므로, 자재 손실률을 크게 줄일 수 있다.Moreover, since the order length is supplied by the production system, the material loss rate can be greatly reduced.
상기 제1빔모듈(5)과 제2빔모듈(6)은 단면상 좌우로 상호 이격되어, 내부에 콘크리트 타설 공간이 형성된다. The first beam module 5 and the second beam module 6 are spaced apart from each other on the left and right in cross-section to form a concrete pouring space therein.
상기 제1빔모듈(5)과 제2빔모듈(6)을 구성하는 채널부재(50, 60)는 상부플랜지(51, 61)와 하부플랜지(52, 62)가 외부로 향하게 배치할 수 있다. The channel members 50 and 60 constituting the first beam module 5 and the second beam module 6 may be disposed so that the upper flanges 51 and 61 and the lower flanges 52 and 62 face outward. .
그러나 상기 강재보(4)는 영구거푸집으로 존치할 수도 있으므로, 사용성이나 내부 콘크리트(C)와의 일체성 도모 등을 위해 상부플랜지(51, 61)와 하부플랜지(52, 62)는 부재 내측을 향하도록 좌우 대칭으로 배치하는 것이 바람직하다. However, since the steel beam 4 can be maintained as a permanent formwork, the upper flanges 51 and 61 and the lower flanges 52 and 62 face the inside of the member for usability or integration with the internal concrete (C). It is preferable to arrange it symmetrically so as to do so.
상기 제1빔모듈(5)과 제2빔모듈(6)의 하부는 하부플레이트(7)로 연결되어, 강재보(4)는 전체적으로 U자형 단면을 형성한다.The lower portions of the first beam module 5 and the second beam module 6 are connected by a lower plate 7, so that the steel beam 4 as a whole forms a U-shaped cross section.
상기 하부플레이트(7)는 별도의 절곡 없이 평판을 그대로 사용할 수 있으며, 강재보(4)의 폭에 따라 적절한 폭으로 절단하여 사용할 수 있다. The lower plate 7 can be used as it is without a separate bending, and can be used by cutting it to an appropriate width according to the width of the steel beam 4 .
상기 하부플레이트(7)는 제1빔모듈(5) 및 제2빔모듈(6)과 별도의 자재로 조립된다. 그러므로 강재보(4)에 작용하는 휨 응력에 따라 하부플레이트(7)의 두께를 자유롭게 선택할 수 있어 경제적 단면 형성이 가능하다.The lower plate 7 is assembled with a separate material from the first beam module 5 and the second beam module 6 . Therefore, the thickness of the lower plate 7 can be freely selected according to the bending stress acting on the steel beam 4, so that an economical cross-section can be formed.
상기 채널부재(50, 60)의 내측면에는 콘크리트(C)와의 일체성을 증가시키기 위해 쉬어스터드(ST)가 부착될 수 있다.A shear stud ST may be attached to the inner surface of the channel members 50 and 60 to increase the integrity with the concrete C.
도 3은 본 발명 강콘크리트 합성보용 강재보의 제2실시예를 도시하는 사시도이다.Figure 3 is a perspective view showing a second embodiment of the present invention for steel concrete composite beams.
도 3에 도시된 바와 같이, 상기 제1빔모듈(5)과 제2빔모듈(6)은 각각 적어도 2단 이상의 기성 채널부재(50a, 50b, 60a, 60b)를 상하로 연결하여 구성될 수 있다. 3, the first beam module 5 and the second beam module 6 may be configured by connecting at least two or more ready-made channel members 50a, 50b, 60a, 60b up and down, respectively. have.
본 발명은 공장에서 대량 생산되는 형강재인 채널부재를 이용하는 것으로, 공장 제작 형강재는 부재의 크기가 한정적이다.The present invention uses a channel member, which is a section steel mass-produced in a factory, and the size of the section steel member manufactured in the factory is limited.
따라서 춤이 큰 강재보(4)가 필요한 경우에는 기성 채널부재를 상하로 서로 접합하여 하나의 빔모듈(5, 6)을 형성할 수 있다.Therefore, when a steel beam 4 with a large dance is required, one beam module 5 and 6 can be formed by bonding the ready-made channel members up and down to each other.
이에 기존에 생산되는 여러 타입의 형강재를 다단으로 조합함으로써 다양한 춤의 강재보(4)를 형성 가능하다.Accordingly, it is possible to form the steel beams 4 of various dances by combining the various types of steel beams produced in the past in multiple stages.
상기 제1빔모듈(5)의 상하로 접합되는 채널부재(50a, 50b)의 플랜지(51a, 52b)는 강재보(4) 내부에 타설되는 콘크리트(C)에 매립되어, 콘크리트(C)와의 일체성을 높임으로써 구조 성능을 향상시킨다.The flanges 51a and 52b of the channel members 50a and 50b joined up and down of the first beam module 5 are embedded in the concrete C poured inside the steel beam 4, and the By increasing the integrity, the structural performance is improved.
마찬가지로 상기 제2빔모듈(6)의 상하로 접합되는 채널부재(60a, 60b)의 플랜지(61a, 62b)는 내부에 타설되는 콘크리트(C)에 매립되어, 콘크리트(C)와의 일체성을 높임으로써 구조 성능을 향상시킨다. Similarly, the flanges 61a and 62b of the channel members 60a and 60b joined up and down of the second beam module 6 are embedded in the concrete C to be poured inside, thereby increasing the integrity with the concrete C. This improves the structural performance.

And Figure 5 is a perspective view showing the coupling relationship of the neighboring pre-assembly module, Figure 6 is a perspective view showing the coupling state of the neighboring pre-assembly module, Figures 7 and 8 show the state before and after the coupling of the separable steel beam It is a cross-sectional view that
도 4 내지 도 8 등에 도시된 바와 같이, 상기 하부플레이트(7)는 제1빔모듈(5)과 제2빔모듈(6)의 하부면에 고정되되, 상기 하부플레이트(7)는 제2빔모듈(6)의 채널부재(60) 하부플랜지(62)와 결합볼트(B)에 의해 고정될 수 있다. 4 to 8, the lower plate 7 is fixed to the lower surfaces of the first beam module 5 and the second beam module 6, and the lower plate 7 is the second beam It can be fixed by the channel member 60 of the module 6, the lower flange 62 and the coupling bolt (B).
보 상부에 슬래브 시공 시, 가설 거푸집 대신 영구거푸집인 데크플레이트를 사용하는 경우가 많다.When constructing a slab on top of a beam, a deck plate, which is a permanent form, is often used instead of a temporary form.
종래 강콘크리트 합성보와 데크플레이트를 이용한 철근콘크리트 슬래브-보 구조물은 기둥 사이나 기둥 사이에 설치된 거더 사이에 강재보를 먼저 설치하고, 이웃하는 강재보 사이에 데크플레이트를 설치한 후 강재보 내부와 데크플레이트 상부에 콘크리트를 타설하는 순서로 시공하였다. In the conventional reinforced concrete slab-beam structure using steel concrete composite beams and deck plates, steel beams are first installed between columns or girders installed between columns, and deck plates are installed between neighboring steel beams, and then the inside and deck plate of steel beams It was constructed in the order of pouring concrete on top.
이때, 데크플레이트의 설치는 복수의 매로 적층된 데크플레이트들을 강재보 상부에 적치한 다음, 각 데크플레이트들을 설치 위치에 판개하고, 데크플레이트를 강재보에 용접 등의 방법으로 고정하였다.At this time, in the installation of the deck plate, the deck plates stacked with a plurality of sheets were placed on the upper part of the steel beam, and then each deck plate was spread to the installation location, and the deck plate was fixed to the steel beam by welding.
이 경우 강재보와 데크플레이트가 각각 별도로 설치되는데다 개별 데크플레이트들을 각자 판개하여야 하므로, 시공 시간이 많이 소요된다. 더욱이 데크플레이트 판개 작업은 강재보 상부에서 고소 작업으로 수행되므로, 작업자 추락 등으로 인한 안전사고 우려가 있다.In this case, since the steel beams and the deck plates are installed separately, and the individual deck plates must be sold separately, it takes a lot of construction time. Moreover, since the deck plate opening work is performed at high altitude on the upper part of the steel beam, there is a risk of a safety accident due to a fall of the worker.
따라서 기존에 강재보와 데크플레이트를 각각 별도로 시공하는 공법과 달리, 본 발명에서는 강재보(4)를 좌우로 분할하여 분할된 제1빔모듈(5)과 제2빔모듈(6)을 데크플레이트(8)와 일체로 구성함으로써 선조립 모듈(3)을 형성할 수 있다(도 4).Therefore, unlike the existing construction method of separately constructing a steel beam and a deck plate, in the present invention, the first beam module 5 and the second beam module 6 divided by dividing the steel beam 4 to the left and the right are used as a deck plate. It is possible to form a pre-assembly module (3) by configuring integrally with (8) (Fig. 4).
이에 상기 데크플레이트(8)의 양단 하부에 제1빔모듈(5)과 제2빔모듈(6)이 구비된 선조립 모듈(3)을 순차적으로 설치하여, 제1빔모듈(5) 및 제2빔모듈(6)이 각각 인접하는 선조립 모듈(3)의 제2빔모듈(6) 및 제1빔모듈(5)과 접합되어 강재보(4)를 형성하게 된다(도 5, 도 6). Accordingly, by sequentially installing the pre-assembly module 3 provided with the first beam module 5 and the second beam module 6 under both ends of the deck plate 8, the first beam module 5 and the first beam module 5 The 2 beam module 6 is joined to the second beam module 6 and the first beam module 5 of the pre-assembly module 3 adjacent to each other to form a steel beam 4 (FIGS. 5 and 6). ).
이 경우 상기 하부플레이트(7)가 제1빔모듈(5)의 하부에 미리 조립된 상태로 선조립 모듈(3)을 설치할 수 있다. 그리고 후 설치되는 선조립 모듈(3)의 제2빔모듈(6)을 상기 하부플레이트(7)의 상부에 거치한 상태에서, 제2빔모듈(6)을 구성하는 채널부재(60)의 하부플랜지(62)와 하부플레이트(7)를 결합볼트(B)로 현장 체결하여 제2빔모듈(6)을 하부플레이트(7)와 결합할 수 있다(도 7, 도 8).In this case, the pre-assembly module 3 may be installed in a state in which the lower plate 7 is pre-assembled under the first beam module 5 . And in a state in which the second beam module 6 of the pre-assembly module 3 to be installed later is mounted on the upper part of the lower plate 7, the lower part of the channel member 60 constituting the second beam module 6 By field-fastening the flange 62 and the lower plate 7 with a coupling bolt B, the second beam module 6 can be coupled to the lower plate 7 ( FIGS. 7 and 8 ).
이와 같이 분할된 강재보(4)를 포함하여 구성되는 선조립 모듈(3)을 사용하면, 복수 매의 데크플레이트(8)와 강재보(4)를 구성하는 제1, 2빔모듈(5, 6)이 일체화된 전체 선조립 모듈(3)을 일괄 시공할 수 있다. 그러므로 양중 횟수를 대폭 줄이고, 시공 시간을 크게 단축할 수 있다.When the pre-assembly module 3 configured to include the divided steel beam 4 is used, the first and second beam modules 5 constituting the plurality of deck plates 8 and the steel beam 4, 6) The entire pre-assembly module 3 in which this is integrated can be collectively constructed. Therefore, it is possible to significantly reduce the number of lifting and significantly shorten the construction time.
특히, 안전사고 우려가 큰 데크플레이트 판개 작업이 공장 또는 지상 작업장에서 미리 이루어지므로 작업 안전성이 매우 우수하다.In particular, the work safety is very good because the deck plate opening work, which has a high risk of safety accidents, is performed in advance at a factory or ground work site.
뿐만 아니라 기존 데크플레이트 공법은 작업자가 일일이 판개 작업을 수행하므로, 작업자가 취급할 수 있는 중량을 고려하여야 했다. 이에 개별 데크플레이트의 크기에 한계가 있어 장스팬 슬래브에 적용하기 어려웠다. In addition, in the existing deck plate method, since the operator performs the plate opening operation one by one, the weight that the operator can handle had to be considered. Therefore, there is a limit to the size of individual deck plates, making it difficult to apply to long span slabs.
이에 반해 본 발명을 이용하는 경우에는 현장에서 작업자의 데크플레이트 판개 작업이 생략된다. 아울러 장비에 의해 데크플레이트(8)가 강재보(4)와 함께 일괄 설치되므로, 데크플레이트(8)의 크기 제한이 없어 장스팬 슬래브에 적용하기 용이하다.In contrast, when the present invention is used, the operator's deck plate opening operation is omitted in the field. In addition, since the deck plate 8 is installed together with the steel beam 4 by equipment, there is no size limitation of the deck plate 8, so it is easy to apply to a long span slab.
상기 하부플레이트(7)는 용접 또는 볼트 결합에 의하여 제1빔모듈(5)에 미리 조립할 수 있다. The lower plate 7 may be pre-assembled to the first beam module 5 by welding or bolting.
이때, 볼트 결합을 위한 결합볼트(B)는 강재보(4)의 하부에서 일방향으로 체결할 수 있도록 일방향 볼트를 사용할 수 있다.At this time, the coupling bolt (B) for bolt coupling may use a one-way bolt to be fastened in one direction from the lower part of the steel beam (4).
도 9는 타이플레이트가 결합된 실시예를 도시하는 사시도이다.9 is a perspective view illustrating an embodiment in which a tie plate is coupled.
도 9에 도시된 바와 같이, 상기 제1빔모듈(5)과 제2빔모듈(6)은 각각 상하부 채널부재(50a와 50b, 60a와 60b)가 결합볼트(B)에 의해 상호 결합되고, 제1빔모듈(5)의 상부 채널부재(50b)와 제2빔모듈(6)의 상부 채널부재(60b)는 대응되는 하부플랜지(52b, 62b)에 체결된 결합볼트(B)에 양단이 결합되는 타이플레이트(9)에 의해 상호 연결될 수 있다. 9, the first beam module 5 and the second beam module 6 have upper and lower channel members 50a and 50b, 60a and 60b respectively coupled to each other by a coupling bolt B, Both ends of the upper channel member 50b of the first beam module 5 and the upper channel member 60b of the second beam module 6 are coupled to the coupling bolts B fastened to the corresponding lower flanges 52b and 62b. They may be interconnected by a tie plate (9) coupled thereto.
U형 단면의 강재보(4)는 데크플레이트 작업하중이나 내부에 콘크리트 타설 시 측압 등에 의해 좌우 웨브가 벌어질 수 있다. The left and right webs of the U-shaped cross-section of the steel beam 4 may be spread by the deck plate working load or lateral pressure when pouring concrete inside.
따라서 ㄷ형강인 채널부재를 다단 적층하여 빔모듈(5, 6)을 형성하는 경우, 빔모듈(5, 6)의 중간에 구비되는 상부 채널부재(50b, 60b)의 하부플랜지(52b, 62b)를 이용하여 좌우 빔모듈(5, 6)을 지지하도록 함으로써 강재보(4)가 벌어지는 것을 방지할 수 있다.Therefore, when the beam modules 5 and 6 are formed by stacking the C-shaped steel channel members in multiple stages, the lower flanges 52b and 62b of the upper channel members 50b and 60b provided in the middle of the beam modules 5 and 6) By using the to support the left and right beam modules (5, 6), it is possible to prevent the steel beam (4) from spreading.
이에 상하부 채널부재(50a와 50b, 60a와 60b)를 결합하기 위해 체결되는 결합볼트(B)에 타이플레이트(9)의 양단을 각각 고정함으로써, 용접 공정 없이 강재보(4)의 웨브를 지지할 수 있다. Accordingly, by fixing both ends of the tie plate 9 to the coupling bolts (B) fastened to combine the upper and lower channel members (50a and 50b, 60a and 60b), respectively, to support the web of the steel beam (4) without a welding process. can

도 10 내지 도 13에 도시된 바와 같이, 상기 타이플레이트(9)는 양측에 상기 결합볼트(B)가 체결되는 제1볼트결합공(91)과 제2볼트결합공(92)이 각각 형성되되, 상기 제1볼트결합공(91)은 제1빔모듈(5) 측의 결합볼트(B)에 회전 가능하게 결합되고, 제2볼트결합공(92)은 타이플레이트(9)의 회전에 의해 제2빔모듈(6) 측의 결합볼트(B)에 결합 가능하도록 제2볼트결합공(92)의 일측이 개방될 수 있다. 10 to 13, the tie plate 9 has a first bolt coupling hole 91 and a second bolt coupling hole 92 to which the coupling bolt B is fastened on both sides, respectively. , The first bolt coupling hole 91 is rotatably coupled to the coupling bolt B on the side of the first beam module 5 , and the second bolt coupling hole 92 is formed by the rotation of the tie plate 9 . One side of the second bolt coupling hole 92 may be opened to be coupled to the coupling bolt B on the side of the second beam module 6 .
상기 강재보(4)를 좌우 분할형으로 형성하여 데크플레이트(8)와 일체화된 선조립 모듈(3)에 적용하는 경우, 상기 타이플레이트(9)는 인접하는 좌우 선조립 모듈(3)을 설치한 후 설치할 수 있다. When the steel beam 4 is formed in a left and right split type and applied to the pre-assembly module 3 integrated with the deck plate 8, the tie plate 9 is installed with the adjacent left and right pre-assembly modules 3 After that, you can install it.
또는, 상기 타이플레이트(9)의 시공 누락을 방지하고, 자재 관리가 편리하도록 타이플레이트(9)를 선조립 모듈(3)의 제작 단계에서 선조립 모듈(3)에 미리 조립할 수도 있다. 이를 위해 상기 타이플레이트(9)의 양측에 제1볼트결합공(91)과 제2볼트결합공(92)을 각각 형성하고, 제1볼트결합공(91)은 제1빔모듈(5)의 상하부플랜지(51a, 52b)를 상호 고정하는 결합볼트(B)에 결합할 수 있다. Alternatively, the tie plate 9 may be pre-assembled to the pre-assembly module 3 in the manufacturing stage of the pre-assembly module 3 to prevent omission of construction of the tie plate 9 and to facilitate material management. To this end, a first bolt coupling hole 91 and a second bolt coupling hole 92 are respectively formed on both sides of the tie plate 9 , and the first bolt coupling hole 91 is the first beam module 5 . The upper and lower flanges (51a, 52b) can be coupled to the coupling bolts (B) for fixing each other.
즉, 상기 타이플레이트(9)는 선조립 모듈(3)의 설치 전 미리 제1빔모듈(5)에 조립할 수 있다. 이때, 상기 선조립 모듈(3)의 제2빔모듈(6)에는 상하부플랜지(61a, 62b)의 접합을 위한 결합볼트(B)만 체결된 상태이다. That is, the tie plate 9 may be assembled to the first beam module 5 in advance before the pre-assembly module 3 is installed. At this time, only the coupling bolts B for bonding the upper and lower flanges 61a and 62b are fastened to the second beam module 6 of the pre-assembly module 3 .
이웃하는 선조립 모듈(3) 설치 시 타이플레이트(9)가 간섭될 수 있으므로, 상기 타이플레이트(9)의 제1볼트결합공(91)은 제1빔모듈(5) 측 플랜지(51a, 52b)에 결합된 결합볼트(B)에 회전 가능하게 결합하여, 제1빔모듈(5) 측으로 타이플레이트(9)를 회전시킨 상태에서 인접하는 선조립 모듈(3)을 설치할 수 있다(도 11). 이후, 상기 타이플레이트(9)를 제2빔모듈(6) 측 플랜지(61a, 62b)에 결합된 결합볼트(B) 쪽으로 회전시켜 제2볼트결합공(92)을 상기 결합볼트(B)에 결합할 수 있다(도 12 및 도 13).Since the tie plate 9 may interfere when the adjacent pre-assembly module 3 is installed, the first bolt coupling hole 91 of the tie plate 9 is connected to the flanges 51a and 52b on the first beam module 5 side. ) by being rotatably coupled to the coupling bolt (B) coupled to the first beam module (5), the adjacent pre-assembly module (3) can be installed in a state in which the tie plate (9) is rotated (FIG. 11) . Thereafter, the tie plate 9 is rotated toward the coupling bolt B coupled to the flanges 61a and 62b on the side of the second beam module 6 to connect the second bolt coupling hole 92 to the coupling bolt B. can be combined ( FIGS. 12 and 13 ).
이를 위해 상기 제2볼트결합공(92)은 일측이 개방되도록 구성하여 상기 결합볼트(B)가 삽입되어 걸리도록 한다.To this end, the second bolt coupling hole 92 is configured such that one side is opened so that the coupling bolt B is inserted and caught.
상기 결합볼트(B)가 미리 체결된 상태에서 타이플레이트(9)의 제2볼트결합공(92)을 제2빔모듈(6) 측의 결합볼트(B)에 결합하기 위해, 제2빔모듈(6) 측의 결합볼트(B)는 완전히 조이지 않은 상태로 설치하였다가 타이플레이트(9)의 제2볼트결합공(92)이 결합된 후 본조임할 수 있다. In order to couple the second bolt coupling hole 92 of the tie plate 9 to the coupling bolt B on the side of the second beam module 6 in a state in which the coupling bolt B is fastened in advance, the second beam module The coupling bolt (B) on the side (6) is installed in a state that it is not completely tightened, and after the second bolt coupling hole 92 of the tie plate 9 is coupled, main tightening can be performed.
물론, 상기 타이플레이트(9)의 단부가 나중에 결합되지 않는 나머지 결합볼트(B)들은 미리 본조임하여 상하부 채널부재를 견고하게 고정시킨다. Of course, the remaining coupling bolts (B) to which the ends of the tie plate (9) are not coupled later are pre-tightened to firmly fix the upper and lower channel members.
도 7, 도 8 등에 도시된 바와 같이, 상기 채널부재(50, 50a, 50b, 60, 60a, 60b)는 플랜지 단부 측으로 갈수록 두께가 감소하도록 내측면이 경사지게 형성되고, 상기 결합볼트(B)에 체결되는 와셔 부재(W) 중 플랜지 내측면에 설치되는 와셔 부재(W)는 플랜지 단부 측으로 갈수록 두께가 증가하는 경사 와셔로 구성할 수 있다. 7, 8, etc., the channel member (50, 50a, 50b, 60, 60a, 60b) is formed with an inner surface inclined so that the thickness decreases toward the end of the flange, the coupling bolt (B) Among the fastened washer members (W), the washer member (W) installed on the inner surface of the flange may be configured as an inclined washer whose thickness increases toward the end of the flange.
상기 채널부재는 상부플랜지 또는 하부플랜지의 두께가 바깥으로 갈수록 감소하는 경사 두께로 이루어진 ㄷ형강일 수 있다.The channel member may be a U-shaped steel having an inclined thickness in which the thickness of the upper flange or the lower flange decreases toward the outside.
이 경우 결합볼트(B)의 헤드나 결합볼트(B)에 체결되는 너트가 플랜지에 제대로 밀착되지 않아 견고하게 고정되기 어렵다.In this case, the head of the coupling bolt (B) or the nut fastened to the coupling bolt (B) does not properly adhere to the flange, so it is difficult to be firmly fixed.
따라서 상기 결합볼트(B)가 체결되는 플랜지가 경사지게 형성된 경우, 플랜지의 경사와 대응되는 경사로 일면이 경사진 와셔 부재(W)를 사용함으로써 결합볼트(B)가 견고하게 채널부재의 상하부플랜지들을 고정하도록 할 수 있다.Therefore, when the flange to which the coupling bolt (B) is fastened is formed to be inclined, the coupling bolt (B) firmly fixes the upper and lower flanges of the channel member by using a washer member (W) whose one surface is inclined with an inclination corresponding to the inclination of the flange. can make it

본 발명 데크-빔 일체형 선조립 모듈(3)은 강재보(4)와 데크플레이트(8)를 영구거푸집으로 활용한 강합성콘크리트 슬래브-보 구조물을 시공하기 위한 것이다.The present invention deck-beam integrated pre-assembly module (3) is to construct a steel composite concrete slab-beam structure using the steel beam (4) and the deck plate (8) as permanent formwork.
상기 강재보(4)는 좌우로 분할되어 일측 부분인 제1빔모듈(5)과 타측 부분인 제2빔모듈(6)로 분리 구성되며, 강재보(4)와 데크플레이트(8)가 일체로 구성된다.The steel beam (4) is divided into left and right, and is configured to be separated into a first beam module (5) on one side and a second beam module (6) on the other side, and the steel beam (4) and the deck plate (8) are integrated is composed of
상기 제1빔모듈(5)은 일측에, 제2빔모듈(6)은 타측에 서로 이격되게 배치한 후, 제1빔모듈(5)과 제2빔모듈(6)의 상부에 데크플레이트(8)를 거치하여 일체화함으로써 데크-빔 일체형 선조립 모듈(3)을 형성한다. The first beam module 5 is arranged on one side and the second beam module 6 is spaced apart from each other on the other side, and then the deck plate ( 8) is mounted and integrated to form the deck-beam integrated pre-assembly module (3).
즉, 분할된 한 쌍의 빔모듈(5, 6) 상부에 복수 매의 데크플레이트(8)를 지상의 작업장 또는 공장에서 미리 판개하여 설치한 후 태크 용접 등에 의해 고정하여 일체로 구성할 수 있다.That is, a plurality of deck plates 8 are pre-opened and installed on the top of the divided pair of beam modules 5 and 6 in a workshop or factory on the ground, and then fixed by tag welding or the like to form an integral structure.
일측 선조립 모듈(3)을 설치한 후 순차적으로 인접하는 선조립 모듈(3)들을 설치하는 순서로 시공할 수 있다. 이때, 일측 선조립 모듈(3)의 제2빔모듈(6)과 인접하는 선조립 모듈(3)의 제1빔모듈(5)을 밀착되게 설치하고, 인접하는 제1빔모듈(5)과 제2빔모듈(6)을 결합할 수 있다.After installing the one-side pre-assembly module (3), it can be constructed in the order of sequentially installing the adjacent pre-assembly modules (3). At this time, the first beam module 5 of the pre-assembly module 3 adjacent to the second beam module 6 of the one-side pre-assembly module 3 is installed in close contact with the adjacent first beam module 5 and The second beam module 6 can be combined.
다시 말하면, 인접하는 선조립 모듈(3)의 인접하는 좌우 빔모듈(5, 6)이 결합되어 U형 단면의 강재보(4)가 형성된다.In other words, the adjacent left and right beam modules 5 and 6 of the adjacent pre-assembly module 3 are combined to form a steel beam 4 of a U-shaped cross section.
본 발명 데크-빔 일체형 선조립 모듈(3)은 조립이 완료된 상태에서는 기존 강재보-데크플레이트 시스템과 동일한 시스템을 구성한다.The present invention deck-beam-integrated pre-assembly module 3 constitutes the same system as the existing steel beam-deck plate system when the assembly is completed.
본 발명에서는 복수의 데크플레이트(8)와 빔모듈(5, 6)이 일체화된 선조립 모듈(3)을 일괄 시공 가능하므로 양중 횟수를 줄이고, 시공 시간을 단축할 수 있다.In the present invention, since it is possible to collectively construct the pre-assembly module 3 in which the plurality of deck plates 8 and the beam modules 5 and 6 are integrated, it is possible to reduce the number of lifting and shorten the construction time.
특히, 데크플레이트(8)의 판개 작업이 공장 또는 지상 작업장에서 미리 이루어지므로 작업 안전성이 우수하고, 장비에 의해 데크플레이트(8)가 강재보(4)와 함께 일괄 설치되므로 데크플레이트(8)의 크기 제한이 없어 장스팬 슬래브 적용이 용이하다. 그러므로 물류창고 등 고하중 장스팬 구조물에 적용하기 유리하다.In particular, since the deck plate 8 is opened in advance in a factory or ground workshop, the work safety is excellent, and since the deck plate 8 is installed together with the steel beam 4 by equipment, the deck plate 8 Long span slab is easy to apply as there is no size limit. Therefore, it is advantageous to apply to high-load long span structures such as warehouses.

도 14 내지 도 17에 도시된 바와 같이, 상기 제1빔모듈(5)과 제2빔모듈(6)은 각각 데크플레이트(8)가 상면에 거치되어 고정되는 상부플랜지(51, 61), 상기 상부플랜지(51, 61)의 일단에서 하부 수직 방향으로 절곡된 웨브(53, 63), 상기 웨브(53, 63)의 하단에서 수평 방향으로 절곡된 하부플랜지(52, 62)로 형성되는 기성 채널부재(50, 60)를 포함하여 구성되어, 상기 제1빔모듈(5)은 이웃하는 선조립 모듈(3)의 제2빔모듈(6)과 하부플랜지(52, 62)가 상호 연결되어 결합됨으로써 강재보(4)가 형성될 수 있다. 14 to 17, the first beam module 5 and the second beam module 6 have upper flanges 51 and 61 to which the deck plate 8 is mounted and fixed on the upper surface, respectively, the A ready-made channel formed by a web (53, 63) bent in the lower vertical direction from one end of the upper flange (51, 61), and lower flanges (52, 62) bent in the horizontal direction at the lower end of the web (53, 63) Consists of including members 50 and 60, the first beam module 5 is coupled to the second beam module 6 and lower flanges 52 and 62 of the neighboring pre-assembly module 3 are interconnected As a result, the steel beam 4 can be formed.
상기 제1빔모듈(5)과 제2빔모듈(6)은 각각 상부플랜지(51, 61), 웨브(53, 63) 및 하부플랜지(52, 62)로 형성되는 기성 채널부재(50, 60)를 포함하여 구성될 수 있다.The first beam module 5 and the second beam module 6 are ready-made channel members 50 and 60 formed of upper flanges 51 and 61, webs 53 and 63 and lower flanges 52 and 62, respectively. ) may be included.
이하, 도 14, 도 15 등의 실시예와 관련하여 일측 선조립 모듈(3)의 제2빔모듈(6)과 인접하는 선조립 모듈(3)의 제1빔모듈(5)이 밀착 설치되어 강재보(4)를 형성하는 경우를 예로 들어 설명한다. Hereinafter, in relation to the embodiments of FIGS. 14 and 15 , the first beam module 5 of the pre-assembly module 3 adjacent to the second beam module 6 of the one-side pre-assembly module 3 is installed in close contact. A case of forming the steel beam 4 will be described as an example.
상기 상부플랜지(51, 61)는 데크플레이트(8)의 단부가 거치되어 고정되는 부분으로, 강재보(4)의 내측 방향 또는 외측 방향으로 절곡 형성될 수 있다.The upper flanges 51 and 61 are portions on which the ends of the deck plate 8 are mounted and fixed, and may be bent in the inner direction or the outer direction of the steel beams 4 .
상기 하부플랜지(52, 62)는 강재보(4)의 내측 방향으로 절곡 형성되는 것으로, 인접하는 빔모듈(5, 6)의 하부플랜지(52, 62)에 연결된다.The lower flanges 52 and 62 are bent in the inner direction of the steel beam 4 and are connected to the lower flanges 52 and 62 of the adjacent beam modules 5 and 6 .
상기 제1빔모듈(5)과 제2빔모듈(6)은 좌우 대칭으로 동일한 형상으로 형성할 수 있다(도 14).The first beam module 5 and the second beam module 6 may be symmetrically formed to have the same shape (FIG. 14).
이때, 하부플랜지(52, 62)의 내측 단부를 상부로 절곡하여 연결편(521, 621)을 형성할 수 있으며, 좌우 연결편(521, 621)을 볼트(B) 등으로 상호 접합하여 강재보(4)를 형성할 수 있다(도 15).At this time, the inner ends of the lower flanges 52 and 62 are bent upward to form the connecting pieces 521 and 621, and the left and right connecting pieces 521 and 621 are mutually joined with a bolt (B) or the like to form a steel beam (4). ) can be formed (FIG. 15).
또는, 도 16, 도 17에 도시된 바와 같이, 선 설치되는 일측 빔모듈(도면상 제1빔모듈(5))의 하부플랜지(52)를 길게 형성하고, 후 설치되는 타측 빔모듈(도면상 제2빔모듈(6))의 하부플랜지(62)는 상부플랜지(61)와 동일한 길이 정도로 짧게 형성할 수 있다. 그리고 일측 빔모듈(5)의 하부플랜지(52) 상부에 타측 빔모듈(6)의 하부플랜지(62)를 거치하여 볼트(B) 등으로 결합할 수도 있다. 이 경우 선 설치되는 빔모듈(5)의 하부플랜지(52) 상면에 후 설치되는 빔모듈(6)의 하부플랜지(62)를 거치하여 안착시키므로, 후 설치되는 선조립 모듈(3)의 설치 높이를 정확하게 맞출 수 있다.Alternatively, as shown in FIGS. 16 and 17, the lower flange 52 of the one side beam module (the first beam module 5 in the drawing) to be pre-installed is long, and the other side beam module (in the drawing) to be installed later. The lower flange 62 of the second beam module 6) may be formed as short as the same length as the upper flange 61 . In addition, the lower flange 62 of the other beam module 6 is mounted on the lower flange 52 of the one side beam module 5, and may be coupled with a bolt (B) or the like. In this case, since the lower flange 62 of the post-installed beam module 6 is mounted on the upper surface of the lower flange 52 of the pre-installed beam module 5, the installation height of the pre-installed pre-assembly module 3 can be precisely matched.
상기 상부플랜지(51, 61)의 상면에는 슬래브 콘크리트와의 일체화를 위해 쉬어스터드(ST)가 부착될 수 있다.A shear stud ST may be attached to the upper surfaces of the upper flanges 51 and 61 for integration with the slab concrete.
전술한 도 7, 도 8에 도시된 바와 같이, 상기 제1빔모듈(5)과 제2빔모듈(6) 중 어느 일측의 하부플랜지(52, 62)에는 접합되는 타측 빔모듈(6, 5)의 하부플랜지(62, 52)와 접합하기 위한 하부플레이트(7)가 결합될 수 있다. 7 and 8, the other side beam module (6, 5) bonded to the lower flange (52, 62) of either side of the first beam module (5) and the second beam module (6) ) of the lower flange (62, 52) and the lower plate (7) for bonding can be combined.
도 14의 실시예에서와 같이, 인접하는 빔모듈(5, 6)의 연결편(521, 621)을 밀착시킨 상태에서 수평 방향으로 볼트(B) 결합하는 경우, 연결편(521, 621)의 높이를 정확하게 일치시키기 어려울 수 있다. As in the embodiment of Fig. 14, when the bolts (B) are coupled in the horizontal direction in a state in which the connecting pieces 521 and 621 of the adjacent beam modules 5 and 6 are in close contact, the height of the connecting pieces 521 and 621 is increased. It can be difficult to match exactly.
따라서 도 16에서와 같이, 선 설치되는 빔모듈(5)의 하부플랜지(52)를 길게 형성하여 후 설치되는 빔모듈(6)을 거치시킬 수 있는데, 이 경우 제1빔모듈(5)과 제2빔모듈(6)의 형상이 달라 부재 제작 및 관리 면에서 비효율적이다.Therefore, as shown in FIG. 16, the lower flange 52 of the pre-installed beam module 5 can be formed to lengthen the beam module 6 to be installed later, and in this case, the first beam module 5 and the second Since the shape of the two-beam module 6 is different, it is inefficient in terms of member manufacturing and management.
그러므로 상기 제1빔모듈(5)과 제2빔모듈(6)을 동일한 규격으로 제작하면서도 후 설치되는 빔모듈(6)을 거치할 수 있도록 일측 하부플랜지(52)에 별도의 하부플레이트(7)를 결합할 수 있다.Therefore, while the first beam module 5 and the second beam module 6 are manufactured to the same standard, a separate lower plate 7 is provided on one lower flange 52 so that the beam module 6 to be installed later can be mounted thereon. can be combined.
상기 하부플레이트(7)는 양측 빔모듈(5, 6)의 하부플랜지(52, 62)와 볼트(B)로 체결 가능하다.The lower plate 7 can be fastened to the lower flanges 52 and 62 of the beam modules 5 and 6 on both sides with bolts B.
상기 하부플레이트(7)는 하부플랜지(52, 62)의 상면에 밀착 설치할 수 있다. 이 경우 좌우 선조립 모듈(3)을 설치한 다음 하부플레이트(7)를 설치해야 하므로, 시공성 측면에서 하부플레이트(7)는 하부플랜지(52, 62)의 하면에 밀착 설치하는 것이 바람직하다.The lower plate 7 may be installed in close contact with the upper surfaces of the lower flanges 52 and 62 . In this case, since the lower plate 7 must be installed after the left and right pre-assembly modules 3 are installed, the lower plate 7 is preferably installed in close contact with the lower surface of the lower flanges 52 and 62 in terms of workability.
즉, 일측 빔모듈(도면상 제1빔모듈(5))의 하부플랜지(52) 하면에 미리 하부플레이트(7)를 결합한 상태에서 일측 선조립 모듈(3)을 설치하고, 후 설치되는 선조립 모듈(3)의 빔모듈(도면상 제2빔모듈(6))을 하부플레이트(7)의 상면에 거치시켜 결합할 수 있다. That is, the one-side pre-assembly module 3 is installed in a state in which the lower plate 7 is previously coupled to the lower flange 52 of the one-side beam module (the first beam module 5 in the drawing), and then the pre-assembly is installed. The beam module (the second beam module 6 in the drawing) of the module 3 may be mounted on the upper surface of the lower plate 7 to be coupled.
상기 하부플레이트(7)는 강재보(4)의 하부플랜지 역할을 하며, 강재보(4)의 하부플랜지(52, 62)는 보의 하부근 역할을 할 수 있다. 이때, 상기 하부플레이트(7)는 두께를 자유롭게 조절할 수 있다. 그러므로 상기 빔모듈(3)은 웨브(53, 63)의 전단력을 지지할 수 있을 정도의 두께로 선택하고, 하부플레이트(7)는 모멘트로 인한 인장력을 기준으로 두께를 선택할 수 있어 경제적인 설계가 가능하다.The lower plate 7 serves as a lower flange of the steel beam 4, and the lower flanges 52 and 62 of the steel beam 4 may serve as a lower root of the beam. At this time, the thickness of the lower plate 7 can be freely adjusted. Therefore, the beam module 3 is selected to have a thickness sufficient to support the shear force of the webs 53 and 63, and the lower plate 7 can be selected based on the tensile force due to the moment, so an economical design is possible. It is possible.
도 18은 이웃하는 선조립 모듈의 설치 과정을 도시하는 사시도이다.18 is a perspective view illustrating an installation process of a neighboring pre-assembly module.
본 발명 데크-빔 일체형 선조립 모듈을 이용한 강합성콘크리트 슬래브-보 구조물 시공 방법은 본 발명 데크-빔 일체형 선조립 모듈을 이용하여 강합성콘크리트 슬래브-보 구조물을 시공하는 방법에 대한 것이다.

상기 (a) 단계에서는 공장 또는 별도의 현장 제작장에서 선조립 모듈(3)을 조립한다(도 4).In step (a), the pre-assembly module 3 is assembled at a factory or a separate on-site manufacturing site (FIG. 4).
제1빔모듈(5)과 제2빔모듈(6)을 좌우로 이격 배치하고, 상부에 데크플레이트(8)를 거치하여 태크 용접 등에 의해 고정함으로써, 선조립 모듈(3)을 조립할 수 있다.By arranging the first beam module 5 and the second beam module 6 apart from each other left and right, and fixing the deck plate 8 on the upper part by tack welding, etc., the pre-assembly module 3 can be assembled.
상기 데크플레이트(8)는 상부에 트러스 거더가 결합된 트러스 데크인 것이 바람직하다.The deck plate 8 is preferably a truss deck having a truss girder coupled thereto.
공장에서 선조립 모듈(3)을 제작하는 경우, 현장 야적하지 않고 운송 차량에서 직접 양중하여 설치할 수 있다. 이 경우 양중 장비의 가동 시간을 줄이고, 공기를 단축할 수 있어 경제적이다.In the case of manufacturing the pre-assembly module 3 at the factory, it can be installed by directly lifting it from a transport vehicle without arranging it on site. In this case, it is economical because the operation time of the lifting equipment can be reduced and the construction period can be shortened.
다음으로, (b) 선 설치된 기둥(1) 또는 기둥(1) 사이에 설치된 거더(2)의 일측에 복수의 상기 선조립 모듈(3)을 횡 방향으로 접하도록 순차적으로 설치하고, 이웃하는 선조립 모듈(3)의 제1빔모듈(5)과 제2빔모듈(6)을 상호 결합한다(도 18).Next, (b) sequentially installing a plurality of pre-assembly modules 3 on one side of the girder 2 installed between the pillars 1 or the pillars 1 installed in the line so as to be in contact with each other in the transverse direction, and adjacent lines The first beam module 5 and the second beam module 6 of the assembly module 3 are coupled to each other (FIG. 18).
즉, 기둥(1)과 거더(2)를 설치한 후 기둥(1) 사이 또는 거더(2) 사이에 선조립 모듈(3)을 순차적으로 설치한다. 그리고 인접하는 선조립 모듈(3)의 빔모듈(5, 6)을 상호 밀착시킨 후 결합하여 강재보(4)가 형성되도록 한다.That is, after installing the pillar (1) and the girder (2), the pre-assembly module (3) is sequentially installed between the pillars (1) or between the girders (2). And the beam modules (5, 6) of the adjacent pre-assembly module (3) are brought into close contact with each other and then combined to form a steel beam (4).
