Description

Turtle neck type horizontally adjustable bridge weight safety transport and support device and construction method in the bridge bearing space}

The present invention is applied to the bridge support space of railway bridges and general bridges (roads, bridges), and more specifically, depending on the weight of the bridge weight or new bridge support to be put on, a turtle that pushes forward like a turtle neck or backwards backward It relates to a device and method for safely transporting and supporting turtle neck-type horizontally adjustable bridge weights on a bridge support space that can be guided to enter the bridge support space while maintaining a level with respect to the bridge support space through the wooden mold leveling.

A bridge bearing is a part installed on the abutment or pier of a bridge to transmit the load of the upper structure to the lower part. It should also be designed to be safe.

Although the durability of bridge bearings has greatly improved compared to the past due to technological development, repair, reinforcement, and replacement are often required due to unexpected problems during use.

In addition, if a certain amount of time elapses after the installation of the bridge, the bridge bearing may be damaged due to the concentration of the load on the bridge or the subsidence of the pier may cause a difference in height between the piers. Therefore, the bridge bearing must be periodically repaired and managed.

When the life of the bridge bearing is over or damaged, it is necessary to replace the bridge bearing for repair and reinforcement, and for this, the upper structure must be lifted to a certain height.

In addition, a structure such as a bridge is composed of a pier and a top plate installed on the pier. Bridges are exposed to the risk of damage due to loads and vibrations weighted by earthquakes or vehicles using the bridges. Therefore, it is necessary to carry out repair work or replacement work to prevent bridge accidents caused by this.

Such bridge repair or replacement work is often performed between piers, abutments or decks of bridges and piers/abutments, and at this time, heavy equipment such as cranes are mainly used to transfer heavy objects required for the work to the work place.

In particular, the bridge performance earthquake-resistant construction site of a structure such as a bridge is located in a narrow and high place, and the problem of securing worker safety, which is a conventional problem that occurs when moving and setting heavy objects to a desired position in a limited space, the process is complicated and the work is complicated There was a problem of low efficiency and a long period of time, so the input cost was high.

In order to solve this problem, as a prior art, Korean Patent Registration No. 10-2410298 has proposed "a jig device for installing heavy objects in a structure and an installation method using the same".

When combined with heavy equipment, since it is combined with a structure that supports the jig device in the lower direction, not in the lateral direction, the heavy equipment coupling part touches the floor of the bridge support space, shortening the access length of the jig device for installing heavy objects. However, it was not possible to access the narrow bridge bearing space, so a separate temporary joint frame had to be installed in order to access the bridge bearing space.

In addition, since the weight of the bridge weight for the new bridge support or bridge lifting equipment is heavy at 100kg to 2000kg, the jig device combined with the heavy equipment is tilted and moved up and down, but the heavy equipment operator cannot know the degree of tilt , Leveling becomes difficult, and at this time, during transportation through the jig device, the weight of the bridge weight is concentrated in one direction, and the fixing device (chain bundle) is broken or loosened, resulting in frequent falling accidents.

And, even if the jig device approaches the bridge support space, the weight of the bridge support is heavy at 200kg ~ 1200kg, so it is difficult to separate it. For this reason, there is a problem in that excessive working time is required and thus the work fatigue of the operator is increased.
