Description

PC beam reconstruction system and the method for bridge beam lifting and tension repair reinforcement using the same method.

The present invention relates to a fish beam mold reinforcing device attached to the bridge device replacement repair device, and to the bridge lifting and tensile repair reinforcement method using the same, for replacement and repair of the bridge device installed between the upper portion of the concrete pier and the fish beam The present invention relates to a device for restoring a fish beam drooping down due to aging to an external steel wire while being provided as an pulling device.

Recently, a bridge device welded to the foundation reinforcement is installed between the upper part of the bridge and the fish beam of the concrete bridge to absorb the load transmitted from the upper structure of the bridge, the vibration of the vehicle passing through the upper plate, or It is widely installed as a vibration isolator for structures such as bridges that transmit and cushion reaction force against the same vibration.

However, in the case of the aging bridge, the construction of a replacement device for the seismic prevention is progressed because the bridge device for the seismic design is not installed.

In order to replace and repair the above-described bridge device, a hydraulic jack is installed between the support plate of the hydraulic jack support member fixed to both sides of the pier by anchor bolts and the fish beam, the fish beam is raised, and the basic reinforcing bar welded on the bridge bridge. The replacement method was to break the buried parts by crushing the anchor parts of the anchor bolts with a crusher such as a hammer drill.

In addition, according to Korean Patent Registration No. 0378382, in the case of the steel jack hydraulic jack lower support device is characterized in that the seating portion is formed on both sides of the channel bracket covered on both circumferential surfaces of the piers covering the upper surface of one side of the piers, the upper support device It depends on the type of bridge. Especially, if the bridge is a concrete bridge, the girder is composed of fish beams, and by using the usual temporary holes constructed on the fish beams, the side brackets are fastened to both upper surfaces of the base plate that are in close contact with the bottom of the fish beams. Although fixed by a member, the method has been suggested to have a coupling hole in which the cap is inserted and supported at both ends of the steel rod penetrating the temporary hole in the upper side bracket at the position corresponding to the temporary hole of the fish beam.

Meanwhile, according to Korean Patent Registration No. 0338490, a plurality of longitudinal square tubes are installed in the longitudinal direction of the superstructure on the upper part of the pier, and are supported on the upper surface of the pier and are supported by the support member. It is characterized in that the hydraulic jack is installed on the hydraulic jack support member to install the hydraulic jack in accordance with the width of the pier to raise the upper structure.

As described above, the device for raising the fish beam to replace and repair the bridge device from the upper part of the pier is based on the source technology filed by the crew 10-2007-110127, which is the source of the pier. It raises the fish beam mounted on the pier of the bridge forming the slope which cannot be installed and installs the hydraulic jacks on the left and right sides of the fish beam arranged in the longitudinal direction of the pier. The hydraulic jack does not escape from elements such as buckling and deformation, and safe work proceeds.In particular, the hydraulic jack is also installed in the upper part of the pier between the fish beam and the fish beam to raise the whole piece beam installed at the upper part of the pier collectively. The work was made easier so that construction costs and air were shortened.

On the other hand, according to the Korean patent registration Nos. 0452495 and 0526995, the support lifting bracket for repairing and strengthening the upper structure of the bridge, and the support raising method therefor, by connecting the H-beam having a certain required strength and the support raising bracket using the steel plate with steel bars It is related to the device and the construction method to reinforce the bridge device by lifting the upper structure of the bridge by using hydraulic jack after installation on both sides of the bridge or the bridge.

For example, in Korean Registered Utility Model Registration No. 0352048, by fixing a fixing bracket which is installed at both ends of the lower part of the fish beam and installing the variable shape birds in the middle of the lower part of the beam, the steel wires are curved and arranged. It prevents secondary cracking and fine-tunes the variable reinforcements so that beam reinforcement can be tuned.

On the other hand, in the Republic of Korea Patent No. 388078 there was a way to repair and reinforce the structure without using the "ㅁ" shaped fixing jacket when the gap between the beam and the beam is not secured during the repair reinforcement of the bridge beam.

As another example, in Korean Utility Model Utility Model No. 0167418, a fixed steel wire anchorage is fixed to the structure with anchor bolts on the left and right sides of the fish beam in the upper part of the piers between the piers, and two birds are installed on the lower edge of the fish beam. A device for restoring a beam, and in a similar manner, in Patent Registration No. 017153, a separate steel is not installed below the fish beam, and the tensile steel is settled in such a manner as to tension the tensile steel in parallel with the bottom of the fish beam. There is a method of tensioning the bracket under the bracket wrapped on both ends and sides of the fish beam.

In order to replace and repair the bridge device installed on the bridge top of the bridge as described above, the various devices to raise the hydraulic jack on the brackets mounted on both sides of the bridge or the top of the bridge, because the fish beam or the upper structure of the bridge is heavy, In the case of the replacement and repair work using heavy materials, the equipment and manpower such as cranes were required a lot, and the equipment and manpower required for dismantling these impression devices after replacing and repairing the teaching device required most of the construction cost. It is occupied.

In addition, most of the bridges that replace and repair the bridge device of the old bridges are bridges built before the seismic design is introduced, or with the recent increase in traffic, the passing loads of these old bridges are increased, so There are many proposals and methods for installing and restoring a fish beam that is drooped to a lower end with a tensile steel wire by installing a fixing device at the bottom.

As described above, the bridge beam lifting device for replacing and repairing the old bridge device of the bridge, or the fish beam tensioning device used as a reinforcement device for reinforcing the deflection phenomenon of the old fish beam, are mostly made of steel plates or steel rods. It is a wasteful factor in the repair work of the bridge as the work is being progressed by the separate device for the replacement of the device or reinforcement of the fish beam.

Accordingly, an object of the present invention is to provide a fish beam by placing a tensioning device in the raising device in consideration of the waste factor caused by replacing and repairing the removing device as a pulling device for replacing and repairing the teaching device presented in the source technology of the present invention. As well as reinforcement, the pier upper structure is further reinforced in preparation for earthquake resistance, and the above-mentioned pulling and tensioning device is installed at all times to increase the passing load during the bridge's service period or to reduce the equipment waste and air during renovation. It is to provide a fish beam mold restoring device equipped with a replacement device for repairing bridge replacement of bridges, and to raise and repair bridges using the same.
