[0003] In consideration of the sound insulation effect and durability,
Many are made of concrete.

[0004] However, the concrete railing not only makes the dead load on the bridge considerable, but also requires time for formwork and concrete curing at the time of construction, making early opening of the road difficult. ing. There is also concern about the adhesive force between the steel slab and the concrete.

[0005] In view of the above, a steel wall column has recently been proposed and commercialized in Utility Model Application Publication No. 30495 in 1990. Unlike the concrete wall balustrade, this wall balustrade does not require any formwork or concrete curing period, shortens the construction period, and is extremely excellent because it is hollow and can greatly reduce dead load. .

[0027]

The present invention has the following effects because it is constructed as described above.

The method of assembling the steel front plate is effective in the post-concrete casting method since the front surface is opened.

The assembly work of the steel base plate, the steel rear plate, and the steel front plate can all be performed on the floor slab.
It is very economical because work outside the bridge can be eliminated and no guard fences or scaffolds are required. In addition, since there is no work on the scaffold for the worker, it is safer.

Since the steel railing has a hollow structure, the dead load can be reduced as compared with the concrete wall railing. The steel wall railing eliminates the need for formwork and concrete curing periods, thus shortening the construction period. Also,
There is no need to worry about the adhesion between the steel deck and concrete.
