Description

Construction method and structure for bridge's footpath

The present invention relates to a pedestrian path that is constructed so that people can safely walk the bridge on which the vehicle runs, and more particularly, there is a difficulty in adding equipment when trying to establish a pedestrian bridge on a bridge that is constructed without securing a pedestrian path. The present invention relates to a method of constructing a pedestrian bridge for the bridge and a structure thereof so that the pedestrian can be easily installed on the bridge.

As the industrial society develops, numerous roads are opened for smooth transportation of logistics, and many roads are still being opened.

The road that is opened as described above may be constructed using the natural terrain as it is, but in order to maximize the use efficiency of the road to build a bridge across the stream or river to increase the use efficiency of the road.

Bridges constructed as described above have been constructed mainly for the purpose of vehicle traffic.

The reason is that in the past, the emphasis was placed on improving economic development, and it was not possible to go back to the historical phenomenon in which all the facilities were constructed.

However, with the recent increase in the quality of life, all the facilities have required people-centered facilities that are not comfortable for human use, and one of them is a footpath ("India") that can safely walk the bridge on foot. Is).

The pedestrian walkway may be constructed along with the bridge construction, or may be constructed in addition to the bridge in use.

The pedestrian walkway in this case is a pedestrian path that is additionally constructed for most old bridges, where there is no pedestrian path and no pedestrians can guarantee safety when crossing the bridge.

There are various ways to secure a pedestrian path on a bridge constructed without a pedestrian path. One of the methods is to divide a portion of the edge of the top plate, which is a roadway in which a vehicle operates, by using a railing, etc., to use it as a pedestrian path.

However, bridges that divide roadways into railings for use as sidewalks have the disadvantage that the distance between pedestrians and vehicles is too close to ensure the safety of pedestrians from vehicles, and the lane width is narrowed by securing the sidewalks. The result is that the bottleneck of the vehicle is being caused, resulting in the closure.

Pedestrian (India), which solves the shortcomings of securing roads by dividing the roadway of bridges, lays down pedestrians on the side of the top of the bridge.

Although the above method can guarantee the safety of pedestrians, various special equipments are required for construction, and special equipments are not only a main cause of the increase of construction cost per hour, but also a special equipment for equipment supply. Not only this was not smooth, but also had difficulty in quick input, which could not shorten the air due to construction.

As described above, a new way of constructing a pedestrian path toward the side of the top plate of a bridge by inserting special equipment is usually performed while the input of special equipment is put under the bridge, and the input of the equipment is performed under the surrounding conditions and the bridge. In some cases, it may be difficult to input the equipment.

For example, there is a building around the bridge, which makes it difficult to secure access roads, or the destruction of a well-maintained park is inevitable when the equipment is turned on due to the parkization of the river floor.

In addition, a conventional bridge pedestrian path is constructed with the same height as the floor surface on which the safety fence is installed and the floor of the pedestrian path.

If the pedestrian walkway is installed at the same height as the floor surface on which the safety fence of the bridge is installed, it is not only able to prevent foreign objects from jumping from the lane to the pedestrian path, but also due to lack of attention, such as children in pedestrians, they may slip or At the same time, the safety problem of falling into the space between the safety fence of the bridge occurred, and when the portable goods carried by pedestrians were displaced around, the portable goods could not be prevented from rolling into the driveway.

This led to the construction of a pedestrian walkway that is more easily constructed and secured by the applicant.

The present invention has been developed in order to solve the conventional disadvantage of the pedestrian path that is laid on the side of the top plate of the conventional bridge, the purpose is to install a fixed bracket consisting of a vertical plate and a horizontal plate on the outside of the safety fence installed on both sides of the bridge top plate In the state where the temporary scaffold for horizontal support installation is fixed to the fixing bracket, the worker climbs on the scaffold of the temporary scaffold member to install anchor bolts necessary to fix the horizontal support, and to fasten the fixing flange to the fixing bracket installed, and thus the main work of the walkway. The horizontal support corresponding to the process can be installed without the need for special equipment, making it possible to construct a pedestrian path on a bridge where it is difficult to put the equipment under the bridge, and to easily construct a pedestrian path. The work by construction is simple, so the air By reducing the use of special equipment that is expensive to operate, and by eliminating the use of special equipment that is expensive to operate, it is possible to significantly reduce other construction costs in the construction of pedestrian paths, and it is possible to construct a pedestrian path without damaging the parked river floor. It can prevent the destruction of the surrounding facilities of the bridge, and the fixed bracket with the horizontal support is the boundary between the roadway and the sidewalk to block foreign substances from the roadway, and the child with low thinking ability slips while walking.
