Metal structure for safety handrail of apartment houses{METAL STRUCTURE FOR SAFETY HANDRAIL OF APARTMENT HOUSE}

The present invention relates to a metal structure for safety railing of an apartment house, and more particularly, to a metal structure for safety railing of an apartment house used as a railing for preventing falls in the apartment house.

The safety railing installed on the veranda of an apartment house is a metal structure that is mainly prepared for safety accidents, and is a structure that is installed on barriers, stairs, verandas, and windows of buildings to prevent falling accidents due to lack of attention or accidents. These safety railings include a structure like a general fence, a pipe fence, and a pipe structure connecting the wall and the wall.

Safety railings used in apartment houses are mainly made of stainless steel pipes for corrosion and aesthetics. These stainless steel pipes are bonded to concrete structures or installed on walls. Stainless steel pipes, such as pipe fences, are fastened to a wall using stud bolts or installed using bolts.

In the existing apartment houses, safety railings are installed as fences to prevent safety accidents on walls where windows are installed, such as verandas. This safety railing is installed as an assembly of stainless steel pipes, and is installed by being coupled to stud bolts, posts, and connectors coupled to the wall.

The safety railing installed on the veranda window of the existing multi-family house as described above is not easy to install and assemble because the length is set according to the width of the entire window installed on the wall, and then is combined with both walls. If there is, it is difficult to repair, and separation is required for window replacement, but there is a disadvantage that separation work is not easy.

In addition, the safety railing of the existing apartment house was assembled by installing posts at regular intervals on the floor of the balcony and using members that can be horizontally arranged like pipes, but the installation structure of the posts and the floor is weak and needs reinforcement. In addition, there was a vulnerability in that the horizontally arranged pipe and the post were not sturdy, so they could not withstand impacts or heavy loads.
