Abstract

A deck integrated with a formwork is provided to utilize a conventional triangular-shaped truss girder, and to achieve automation of manufacturing process by attaching a framework board with a predetermined width onto the truss girder. A deck integrated with a formwork comprises a triangular-shaped truss girder(1) comprising an upper steel wire(11), a lower steel wire(12), a lattice(13), and a bridge(14), a formwork board(2) made of plywood, plastic, or aluminum, and a joint unit(3). The triangular-shaped truss girder is connected to the formwork board by the joint unit. A crossbar attached with a nut is mounted onto the bridge of the truss girder, and is bolted from the lower side of the formwork board.

Description

삼각형 트러스 거더를 이용한 거푸집 일체형 데크{Truss Deck with Formwork Board using the Triangular-shaped Truss Girder}Truss Deck with Formwork Board using the Triangular-shaped Truss Girder}

도 1은 삼각형 트러스 거더(1)와 거푸집 판재(2)가 연결장치(3)로 부착된 거푸집 일체형 데크의 입체도이다.1 is a three-dimensional view of a formwork integrated deck with a triangular truss girder 1 and a formwork sheet 2 attached to a connecting device 3.

도 2는 상기 단면도이며,2 is a cross-sectional view,

도 3은 부분 측면도이다.3 is a partial side view.

도 4a내지 도 4e는 본 발명의 바람직한 연결장치(3)이다.4a to 4e show a preferred connecting device 3 of the invention.

본 발명은 삼각형 트러스 거더가 부착된 거푸집 일체형 데크에 관한 것이다.The present invention relates to a die integral deck with a triangular truss girder attached.

종래의 일체형 데크는 트러스 거더에 철판을 부착한 철판 일체형 데크와 일자형 트러스 거더에 거푸집용 판재를 부착한 거푸집 일체형 데크가 있다.Conventional monolithic decks include an iron plate integral deck having an iron plate attached to a truss girder and a die integral deck having a form plate attached to a straight truss girder.

철판 일체형 데크는 트러스 거더와 직교하는 방향으로 하부 철근을 배근하지 않아 2방향으로 응력을 부담하지 못하므로 구조적으로 만족스럽지 못하고 철판이 콘크리트 슬래브의 하부에 존치됨에 따라 자원의 낭비가 우려되며 장기적으로 철판의 부식으로 인한 보수 및 보강이 필요하다.Since the steel plate integrated deck does not reinforce the lower reinforcing bar in the direction perpendicular to the truss girder, it cannot bear stress in two directions, so it is not structurally satisfactory and there is concern about waste of resources as the steel plate is located under the concrete slab. Repair and reinforcement are needed due to corrosion.

또한 기존의 거푸집 일체형 데크는 대형 판넬로 제작함에 따라 자동화가 불가하므로 비용이 증가되고 생산성에 한계가 있다.In addition, since the existing formwork deck is not manufactured by large panels, automation is not possible, which increases cost and limits productivity.

본 발명은 상기 철판 일체형 데크의 생산과 동일한 방법으로, 철판 일체형 데크의 삼각형 트러스 거더에 소정 폭의 거푸집 판재를 부착하여 거푸집 일체형 데크를 구성하므로서 기존의 철판 일체형 데크의 문제를 해소함과 동시에 기존의 삼각형 트러스 거더를 활용하고 자동화가 가능하게 하고자 함에 목적이 있다.The present invention in the same manner as the production of the iron plate integral deck, by attaching a formwork plate of a predetermined width to the triangular truss girder of the iron plate integral deck to form a formwork integral deck, while solving the problem of the existing iron plate integral deck and at the same time The purpose is to utilize the truss girder and to enable automation.

또한 기존의 철판 일체형 데크는 철판이 연속적으로 트러스 거더에 부착되나 거푸집 판재는 길이 방향으로 여러장을 부착해야 하는바, 불연속적인 거푸집 판재가 트러스 거더와 합성하여 거동함에 있어 철판 일체형 데크와 구조성능이 유사함을 확인하였으며, 기존의 삼각형 트러스 거더에 거푸집 판재를 부착한 후 콘크리트가 경화한 후 거푸집 판재를 해체할 수 있는 연결장치를 제공함에 목적이 있다.In addition, the existing steel plate integrated deck is attached to the truss girder continuously, but the formwork should be attached to the multiple sheets in the longitudinal direction. The similarity was confirmed, and the object of the present invention is to provide a connecting device for dismantling the formwork after the concrete is hardened after attaching the formwork to the existing triangular truss girder.

도 1은 상부 철선(11)과 하부 철선(12)과 래티스(13)와 다리(14)로 구성된 삼각형 트러스 거더(1)가, 소정 폭의 합판이나 플라스틱이나 알루미늄등의 거푸집 판재(2)와, 연결장치(3)로 부착된 거푸집 일체형 데크의 입체도이다.1 shows a triangular truss girder 1 composed of an upper steel wire 11, a lower steel wire 12, a lattice 13, and a leg 14, and a formwork sheet 2 of plywood, plastic, aluminum, etc. having a predetermined width; , Is a three-dimensional view of the formwork integrated deck attached to the connecting device (3).

도 2는 삼각형 트러스 거더를 이용한 거푸집 일체형 데크의 단면도이며, 도 3은 부분 측면도이다.2 is a cross-sectional view of the formwork integrated deck using a triangular truss girder, and FIG. 3 is a partial side view.

도 4a내지 도 4e는 본 발명의 바람직한 연결장치(3)이다.4a to 4e show a preferred connecting device 3 of the invention.

도 1 내지 도 3의 연결장치(3)는 볼트 및 너트를 사용한 도 4a의 연결 장치 이며, 삼각형 트러스 거더(1)의 다리(14)위에 너트가 부착된 크로스 바(cross bar)를 부착하고 거푸집 판재의 하부에서 볼트를 체결한 것이다. 그러나 자동화의 공정에 따라 거푸집 판재(2)에 볼트와 너트를 고정하고 삼각형 트러스 거더(1)를 위치한 다음 크로스 바(cross bar)를 너트와 다리에 동시에 용접하는 것이 바람직하고, 또는 거푸집 판재(2)에 크로스 바(cross bar)가 부착된 너트와 볼트를 고정한 후 상부에 삼각형 트러스 거더(1)를 위치하여 용접할 수도 있다.The connecting device 3 of FIGS. 1 to 3 is the connecting device of FIG. 4A using bolts and nuts, and attaches a cross bar with a nut to the leg 14 of the triangular truss girder 1 and forms a die. The bolt is fastened at the bottom of the plate. However, according to the process of automation, it is preferable to fix the bolts and nuts on the formwork plate 2, to position the triangular truss girder 1, and then to weld the cross bars to the nuts and the legs simultaneously, or After fixing the nuts and bolts to which the cross bars are attached, the triangular truss girders 1 may be positioned and welded at the top.

도 4b는 웨지형의 연결 장치이며, 도 4c내지도 4e는 클립 타입의 연결장치이다.4B is a wedge-shaped connecting device, and FIGS. 4C to 4E are clip-type connecting devices.

기존의 철판 일체형 데크는 슬래브 공사에 있어서 신공법으로 공사기간을 단축하고 정밀시공 및 시공안전등의 장점이 있어 광범위하게 사용되고 있으나 콘크리트 하부에 철판이 존치되는 단점이 있다. 본 발명은 기존의 철판 일체형 데크에 사용되는 삼각형 트러스 거더를 활용하므로서 중복투자를 피하고 기존의 철판 트러스 데크의 장점을 계승하되 단점을 보완한 새로운 공법이 될 것이다.Existing iron plate decks are widely used in slab construction due to the new construction method for shortening the construction period and providing advantages such as precision construction and construction safety. The present invention will be a new method to avoid the overlapping investment and inherit the advantages of the existing steel sheet truss deck by utilizing the triangular truss girder used in the existing steel plate integrated deck, but to compensate for the shortcomings.
