Description

Gang form

The present invention relates to a gang foam, and more particularly, to a gang which enables an operator to climb up and down the operation stool of a cage in a building slab.

Korean Patent No. 10-0607451 (registered on July 25, 2006) discloses an " opening and closing type safety ladder ". The left and right inner ladders are connected to the left outer frame and the right outer frame by the safety footrests. The left and right inner frames each having the operation pedestal mounted on the inner side of the left outer frame and the right outer frame, As the frame is connected by the hinge, when the left and right inner frames mounted with the operation footrest are rotated relative to the right outer frame by the hinge, passages are formed between the left and right outer frames.

However, the above-described safety ladder for opening and closing is intended to climb from the lower level work platform to the upper level operation platform, which is different from the worker's approach from the slab to the operation platform of gang-foam.

Korean Patent No. 10-0788813 (registered on December 18, 2007) discloses "gang form for open structure construction ". The open gantry for constructing the open structure includes a plurality of horizontal or vertical frames, a work space provided with side supports and foot plates on the side and bottom of the vertical frame, and a known gantry composed of a plurality of bolts, A vertical bar, a vertical bar, and a horizontal bar fixedly connected to the vertical bar, a rotary shaft for rotating the vertical bar, and a spring fixed to the vertical frame at one end and fixed at the other end do.

However, the construction for opening the above-mentioned structure does not disclose a structure for the worker to climb from the slab to the work platform of the gang-foam.

Korean Patent Laid-Open Publication No. 2014-0133141 discloses a "gang form ladder ". The gangway ladder is mounted on the gang form and is configured so that the worker can safely move up and down between the slab and the gang form work platform.

However, the conventional gang-shaped ladder may cause the ladder to interfere with the outer wall of the building (the outer wall cured by the gang-bom) when the folding link is folded, but the ladder is positioned outside the opening of the gang. Especially, when the gang form is lifted while the ladder for gang form is not folded, the ladder may collide with the outer wall of the building, resulting in a large safety accident.

In addition, existing gangway ladders may act as obstacles in the installation of the euro foam installed on the inner side of the outer wall of the building while being mounted on the gang-foam.

In addition, the existing gang-designed ladder is placed under the operation platform even in the collapsed state, so that the operator located on the operation platform can not perform the operation of reopening the ladder.

In addition, existing gangway ladders are located outside the gangway, which can damage the outer wall of the building due to collision and contact with the exterior wall of the gang during the gang lifting process.

The present invention seeks to provide a gang form that allows an operator to safely ascend and descend from a building slab to a gang-foot scaffold.

An object of the present invention is to provide a gang form capable of preventing a safety accident that may be caused by a ladder provided for entering and exiting a worker during gang lifting.

The present invention intends to provide a gantry in which a ladder is securely fixed to an outer formwork against external shock or vibration.

The objects of the present invention are not limited thereto, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a steel plate comprising: a steel plate for forming an outer wall of a building and having an opening corresponding to a window of an outer wall of the building; an outer formwork including horizontal columns and vertical columns installed on a rear surface of the steel plate; A cage provided at an outer side of the outer formwork and provided with a multi-stage operation platform for providing a work path, which is a moving path of an operator; And a ladder disposed between the vertical columns of the outer formwork and mounted on the cage so that an operator can move the slab of the building through the opening and the work footrest; The ladder being fixed to a work foot of the cage; To provide a gantry comprising a base ladder member and an extended ladder member which are pivotally mounted on the stationary member and extend vertically on the side of the work passage and are folded over the slab of the building through the opening by a spreading operation do.
