Description

{Safety passage facility having prefabricated deck}

The present invention relates to a safety passage facility used as a foot bridge, an inspection passage, a pedestrian, and a bicycle passage. Particularly, since a bottom plate can be installed without a piece and a reinforcing plate is provided, there is no fear of breakage, The present invention relates to a safety passage facility having a built-in deck that can be easily and easily installed, is easy to drain, reinforces the rigidity of the railing, and facilitates the deformation of the railing.

For example, a floor plate is installed when a foot bridge is installed to secure a bicycle or a pedestrian's passage in the bridge. The bottom plate is generally made of wood and fixed through the piece. Therefore, since the bottom plate is fixed by the piece portion, the bottom plate is weakened at the piece portion, and the bottom plate is easily broken or broken. If the bottom plate is damaged, pedestrians or bicycles can be dangerous and safety accidents can be caused.

The technology to be a background of the present invention is Korea Registered Patent Registration No. 10-1283014, A vertical angle adjusting and fixing unit coupled to the vertical axis so as to be vertically adjustable; A base support member coupled to the vertical angle adjusting and fixing unit in a cantilever manner so as to be adjustable in a horizontal direction; A footrest fixing member coupled to the base support member so as to be rotatable about the longitudinal direction of the base support member; And a fixing unit for fixing the foot fixing member to the base supporting member. Therefore, since the pedestal fixing member is fixed in a state where the angle is inclined according to the inclination of the road, the contact area between the pedestal fixed to the pedestal fixing member and the pedestal fixing member is widened to firmly support the pedestal, Is robust and safe.

However, in the background art, there is no coupling structure between the footrest and the footrest fixing member to which the footrest is fixed, so that the footrest can not be easily installed. Also, since there is no connection means between the footrests, precise alignment is difficult when the footrests are installed.
