Abstract:
A prefabricated reinforcing bar arrangement structure is provided to minimize the usage of reinforcing bars by arranging connecting bars of vertical and horizontal ladder type truss bars crisscross not to overlap with each other, to heighten work efficiency to the maximum and to shorten a period of work by using a connecting bar of a ladder type truss bar as a form tie. A prefabricated reinforcing bar arrangement structure is formed by placing many ladder type truss bars(110,120) in horizontal and vertical directions and rotating the vertical ladder type truss bars in a 90-degree arc to cross each other and to integrate the ladder type truss bars. The ladder type truss bars are composed of two main reinforcing bars(111,121) placed parallel to each other at a certain distance and many connecting bars(112,122) connected at right angles to the main reinforcing bars, wherein the connecting bars of the horizontal ladder type truss bars are arranged correspondingly to the interval of the arranged vertical truss bars, and the connecting bars of the vertical ladder type truss bars are arranged correspondingly to the interval of the arranged horizontal truss bars, so that the connecting bars of the vertical and horizontal ladder type truss bars are arranged to cross each other not to be overlapped, thereby to form an optimum reinforcement structure for a reinforced concrete structure with minimum quantity of reinforcing bars, and two ends of the connecting bar are projected to the lateral direction of the main reinforcing bars to function as a form tie.
Abstract:
A reinforcing bar distributing structure is provided to remove a process of installing a mold fixing device by using connecting reinforcing bars of a trapezoidal truss bars as a mold fixing device, and to remove a process of installing spaces by maintaining a gap of the mold by the connecting reinforcing bars. A reinforcing bar distributing structure comprises a plurality of slope truss bars(900), and a plurality of trapezoidal truss bars(950). The slope truss bars include two main reinforcing bars(901) arranged with a predetermined gap, and slope reinforcing bars(902) having continuous wavelength and connecting two main reinforcing bars. The trapezoidal truss bars include two main reinforcing bars(951) arranged with a predetermined gap, and a plurality of connecting reinforcing bars(952) vertical to the two main reinforcing bars. One end or two ends of the connecting reinforcing bars are projected to the side direction of the main reinforcing bars.

본 발명은 보강철근이 일체로 부착된 데크플레이트와 대형거푸집을 이용하여 구조물을 바른됫박형으로 구축해 가는 거푸집 공법에 관한 것이다. 대형거푸집은 거푸집널, 거푸집틀 및 수직지지대로 구성되며, 수직지지대는 슬래브 거푸집을 관통하여 아래층 벽체에 고정된다. 슬래브 거푸집으로는 재래식 일반 거푸집 또는 보강철근이 부착된 데크플레이트를 사용하며, 슬래브 거푸집과 상부 벽체 거푸집을 함께 설치하여 콘크리트 구조물을 바른됫박형으로 타설한다. 슬래브 거푸집 설치, 슬래브 철근의 배근과 슬래브 콘크리트 타설의 편의를 위해 벽체 대형 거푸집널의 하단부는 상하로 개폐할 수 있도록 하였으며, 벽체 콘크리트가 슬래브 쪽으로 융기하는 것을 방지하기 위하여 벽체 대형거푸집의 하단 거푸집 내부에 물결나비형 스프링 와이어와 메탈라스를 함께 설치한다. 본 발명의 슬래브 벽 분리 타설식 대형거푸집 공법을 이용함으로써, 내벽에도 대형거푸집을 이용할 수 있어 보다 경제적이고 신속한 구조물의 축조가 가능하게 되었다. 또한 거푸집 상승재의 설치 및 이동이 간편한 소형의 전동식 유압잭을 이용함으로써 대형 중장비를 사용하지 않아 경제적인 시공이 가능하다.
Abstract:
PURPOSE: An in-corner and out-corner assembling devices for a separative slab wall casting gang form using a reinforcing bar attached deck plate are provided to optimize a combination of the inside and the outside of a gang form and to easily use the existing gang form though varying a thickness of a wall. CONSTITUTION: An in-corner assembling device comprises: an L-shaped steel plate(51); an in-corner form frame(52) stuck to both ends of the steel plate with bolts(53) vertically; a grip(56) to combine a form frame(22) of a gang form and to form bolt holes(57); bolts(58) inserted inside the form frames by penetrating through the bolt holes and extended over both blades of the form frames when rotating at 90degrees; and nuts(59) combined with the bolts. The form frame and a form sheathing board(24) are combined with the bolts. The form frame is moved leftward and rightward by forming an oval hole(22a) in the form frame. An out corner assembling device comprises a hook to fix two form frames by forming a protruding portions to shield the form frame and to be inserted in the groove; an assembling blade extended in perpendicular to the hook, to form a hole in the center and stuck nuts in the hole; and bolts inserted between the groove of the form frame by combining with the nuts.

Abstract:
PURPOSE: An oil hydraulic jack for a lifting separative slab wall casting gang form using a reinforcing rod attached deck plate is provided to easily pull a gang form though a thickness of a wall is varied. CONSTITUTION: An oil hydraulic jack(90) for lifting a gang form comprises: an oil hydraulic jack frame(91) to form a first hollow(96) to be filled oil(100) and a second hollow(97); a first cylinder(92) slid inside the second hollow by inserting therein, to form a third hollow(98) and protruded on the hydraulic jack frame; a second cylinder slid inside the third hollow by inserting therein and protruded on the first cylinder; an oil hydraulic cylinder(94) to form a fourth hollow(99) to be reciprocated a piston(95) and to pressurize the oil in the second hollow and the fourth hollow through the reciprocation of the piston by connecting the fourth hollow with the first hollow and the second hollow; and a changing portion to change the rotational motion of an electromotor to the rectilinear reciprocating motion by connecting the electromotor with the piston. Thereby, a building is economically and quickly constructed with the gang form in an inner wall.
