The present invention relates to a lifting method of the sliding foam, and more particularly, to a lifting method of the sliding foam to quickly lift the sliding foam without separating the gang form from the outer wall.

As is well known, in order to improve workability and safety, GCS (Guide Climbing System), which is installed to be elevated on the guide rail and is lifted up by a tower crane, and hydraulic cylinders are installed on the guide rail to raise the gang form by itself. ACS (Automatic Climbing System) is widely used, and GCS and ACS are collectively referred to as sliding foams.

Such a sliding foam is composed of a gang foam, a cage, an upper cage, a lower cage, etc. The weight of the structure is more than 3 tons, so the guide rail is fixed as a safety device to prevent a safety accident due to the falling of the sliding foam.

The installation state of the conventional sliding foam is schematically shown in Figures 1a to 1c.

As shown in the figure, the sliding foam is fixed to the outer wall bracket (100), the guide rail 120 to be guided by the tower crane to be raised, the vertical frame 140 is installed in the rear of the guide rail 120, The gangform 160 is installed above the vertical frame 140 and the cage 180 is installed at the rear of the vertical frame 140 and the like.

In addition, the fixing bracket 100 is firmly fixed to a plurality of anchor bolts 101 on the outer wall of the building structure, the inner side of the rotating member 103 is formed with a locking groove (103a) to be rotatable to the locking pin (102) The guide channel 105 is installed to guide the guide channel 120 to the rear thereof, that is, to the right in the drawing. Along with this, the guide rail 120 is fixed at the same position as the pivot member 103 of the fixing bracket 100 so that the locking member 121 for fixing the guide rail 120 is coupled and fixed to the locking groove 103a. The locking protrusion 121a is formed, and the lifting hook 122 is fixed to the uppermost end of the guide rail 120 so that the lifting hook of the tower crane is caught.

In addition, the guide rail 120, the cage 180 is installed so as to perform the removal work of the outer wall, etc., the first horizontal frame 141 on top of the guide rail 120 and the cage 180. It is fixed, the first vertical frame 142 is fixed to the upper surface thereof. In addition, the second horizontal frame 143 is fixed to the upper portion of the vertical frame 142, the working footrest 144 having a predetermined thickness is fixed to the upper surface thereof.

In addition, the second horizontal frame 143 is installed with a pinion gear 145 which is driven and rotated by a motor (not shown in the drawing), and a rack 146 fitted thereto is installed, and on one side of the rack 146. The second vertical frame 147 is fixed, the inclined support frame 148 is fixed to the other ends of the second vertical frame 147 and the rack 146, the gangform 160 in front of the second vertical frame 147 ) Is installed, the work table 161 is installed at the rear thereof.

Fastening the tie bolts 162 to the inner and outer gangform 160 so that the outer wall of the building structure is constructed using such a sliding foam, and then the concrete is poured and cured to construct the outer wall. Since the sliding foam has a thickness of the gangform 160, that is, the thickness from the gangform 160 to the second vertical frame 147 is thicker than the thickness of the guide rail 120, the lifting hook of the tower crane lifts the hook 122. There is a discomfort that can not be placed, according to the power supply to the motor installed in the second horizontal frame 143 in order to raise the sliding form consisting of the guide rail 120, the gang form 160 and the cage 180 is integrated By rotating the pinion gear 145 to move the rack 146 to the rear and to move the second vertical frame 147 and the gangform 160 to the rear, and then lifting the hook of the tower crane in the lifting ring 122 There was a difficulty to raise the sliding foam by the operation of the tower crane.

In addition, since the pinion gear 145 and the rack 146 must be installed in order to retract the heavy chain gangform 160, the weight of the heavy body becomes heavier, making it difficult to secure safety, and the gangform 160 is retracted. In order to maintain the standing state of the gangform 160, there is a problem in that the support structure such as the inclined support frame 148 is required separately, which makes the structure complicated.

An object of the present invention devised to solve the above problems is to raise the sliding form to quickly raise the sliding form without the work process for the retraction of the gang form and return to the original position by simplifying the structure of the sliding form To provide.
