Description

BICYCLE BRIDGE HAVING LONG SPAN CONNECTION AS USING PRECAST CONCRETE PANELS}

The present invention relates to a bicycle bridge, and more particularly to a bicycle bridge for long-term connection using a precast concrete panel that is connected between the streams in a long distance between the streams so that the bicycle can cross the river.

Recently, as the use of bicycles is rapidly increasing, the necessity of bicycle bridges for the passage of bicycles is increasing. In the case of the conventional bridges, due to the heavy and large bridge superstructure, the bridge and the coping portion supporting it is huge, it required a considerable cost and time to construct it.

However, in the case of bicycle bridges, only bicycles and pedestrians pass, and although the bridges are small in size, it is difficult to construct a bridge suitable for such a bicycle bridge by simply reducing the size of a conventional bridge. On the other hand, in the yard where the need for bicycle bridges increases, there is an urgent need for bridges that can be constructed quickly and at low cost.

In more detail, when there are well-equipped grounds such as bicycle paths, pedestrian paths, and sports facilities on both sides of the river, bridges must be used to cross the river by bicycle or to walk. Since there are no bridges built exclusively for crossing, there is no choice but to cross the road using vehicle bridges constructed in the distance. Therefore, after moving to the vehicle bridge along the riverside facility, it is necessary to cross the vehicle bridge and move to the riverside facility on the opposite side, so there is a problem in that it takes a long time from the user's perspective.

As a technology conceived as a bicycle bridge is installed so that the bicycle can cross the river, Patent Publication No. 10-2011-0087877, Patent Publication No. 10-2011-0089894, Patent No. 10-1054741, Registered Patent 10-1027162, Patent No. 10-1124337, Patent No. 10-1120672, Patent No. 10-1118120, Patent No. 10-1171041 and the like.

The Patent Publication No. 10-2011-0087877, there is a problem that the total stress of the hypothesis delivery is not enhanced because the support arms do not strain each other, the Patent Publication No. 10-2011-0089894, the guiding guide portion and the frame In addition to the structure of the top plate, this also shows the problem of stress increase due to the structure that the girder guide and the frame do not strain each other, and provides the girder without submerging by making the girder adjustable according to the water height as a purpose and effect. Compared with the object and purpose of the present invention, different techniques are clear, and Patent No. 10-1054741 provides a method for constructing a bicycle road by providing a lateral support that is laterally padded between a first support and a second support. Proposed but still there is a limit to increase the stress by failing to achieve the tension between the first support, the second support and the transverse support, the Patent No. 10-1027162, By installing concrete panels made of precast on pile heads buried at regular intervals, bicycle bridges are provided only by the connection between these concrete panels. Too many of these are not suitable for making long-to-long connections, and Patent No. 10-1124337 is a technology for providing a structure that can be traversed by both bicycles and pedestrians. It is a structure that puts girder and installs slab on the girder, so it is not possible to achieve tension between the pier coping part and the girder, thereby revealing a problem in the stress increase, and it is possible to perform the walk by providing a pedestrian structure separately on the side of the bicycle structure, but manufacturing cost and construction There is a costly problem, and Patent No. 10-11 No. 20672 provides a prefabricated bridge by mounting the top plate on the left and right ends of the girders fitted on the pile, which also does not form a tension between the girder and the top plate represents a problem in stress, Patent No. 10-1118120, This is a technology in which bicycle structures are installed on the left and right sides of bridges, which implements bicycle structures using existing bridges, and therefore, it is impossible to connect the bridges in rivers substantially. Patent No. 10-1171041 describes one side of an existing bridge. Bury the pile on the bridge side, and fix the bracket for fixing at regular intervals and install the mold for pile on the pile to fix the upper horizontal beam between the fixing bracket and the pile mold and on the upper side of the upper beam beam. After padding the channel members at regular intervals, the deck is installed on the upper part of the channel member to provide a bicycle road. However, in implementing the bicycle road, the components required as described above are unnecessarily high, which makes production and construction costs high, and uses existing bridges, which is structurally unstable to achieve long-term connection, and also increases the overall stress of the bicycle road. It is a difficult technique.

Therefore, these conventional bicycle bridge technologies, when installed in the river can not be enhanced the overall stress of the bridge, resulting in poor construction, as well as the long-term connection is not possible due to the structural mechanism of the bridge, manufacturing and construction costs You will have a lot of problems.
