In general, a cantilever bracket is a structure for supporting a form for pouring concrete at the edge portion of a bridge top plate. The road surface of a road bridge is formed so that when the vehicle is running, With slight angular deviation. The concrete pavement of the bridge bridge roof is constructed by assembling the work platform so that the concrete pouring form can be installed, and then the worker moves on the work platform and the cantilever bracket is installed after the angle is adjusted by viewing the drawing on the ground. The concrete for the concrete pouring is installed on the concrete pavement, and the concrete is laid on the installed concrete for the curing.

The prior art of such a cantilever bracket includes a cantilever bracket with a variable angle and a cantilever having a cantilever with a partition formed therein, as disclosed in Japanese Patent Laid-Open No. 10-0891985 Structure) is provided.

These prior art cantilever brackets that can be adjusted in angle can solve the problem of producing cantilever brackets according to the height of the shifts in each field, thus reducing the work efficiency and cost, and the cantilever brackets can be installed under the formwork It is possible to solve the deterioration of the workability of the angular error correcting process. Further, the structure of the extension pedestrian bridge using the cantilever with the partition wall has an octagonal shape around the cantilever, and a plurality of partition walls are formed in the hollow interior space to improve the bending strength and the torsional strength, Construction can be made more easily from the improved cantilever structure, which can shorten the construction period, reduce the construction cost by reducing the materials used for the improvement of the strength, and improve the safety from the rigid structure. .

However, since the cantilever brackets of the prior arts are installed one by one to adjust the angle, the construction work can not be continuously performed and the workability is lowered. Moreover, since the cantilever brackets are vulnerable to safety, Which is a problem in safety.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus and a method for forming an upper beam by using an elongate molding apparatus previously assembled on the ground, Which is excellent in workability due to assembly of a mold by assembling a long section at both ends in a short period of time, and is capable of performing a safe operation.

According to an aspect of the present invention, there is provided a lithographic apparatus comprising: a plurality of upper beams vertically installed between upper pierced upper portions; And a horizontal connecting frame which is detachably fastened to the rear surface of the horizontal rectangular frame and which is detachably fixed to the rear of the horizontal rectangular frame. And a horizontal connection panel supporting means for securely supporting the horizontal connection panel and adjusting the angle thereof.

According to the present invention, an elongated formwork apparatus previously assembled in an appropriate length on the ground is assembled in a long section of both ends of an upper beam installed in a longitudinal direction on a high bridge pier, The workability of the form assembly is excellent as compared with the installation method, and a safe work can be performed without installing a safety net in the lower part by installing the form at a time.
