Description

Bracket for holding up bridge manufactured with steel plate and constructing method of bridge hold-up system the bracket}

The present invention relates to a unit bridge lift bracket using a steel plate and a bridge lift construction method using the same, having a "b" shape to be installed on the pier or alternately formed on the top of the bridge grooves and the anchor groove formed at the same position as the anchor groove position formed on the support steel sheet. A plurality of supporting steel plates and supporting steel plates which are integrally stacked and connected to the supporting body and the supporting body, have a connecting hole into which a bracket connecting supporting rod or an alternating connecting supporting rod is inserted, and an anchor groove into which an anchor to be fixed to a pier or alternating part is inserted. It is connected at right angles, but the jack support plate is mounted on the upper part, and the fixing plate groove formed at the center to be connected with the fixing bolt is formed at the center and the connecting hole for inserting the unit bridge lifting bracket connecting rod to the unit bridge lifting bracket at the lower part of the connecting plate. Unit bridge lift brackets with three lower vertical plates installed at regular intervals

The unit bridge lifting brackets are installed on both sides of the pier, the anchor bolt is fixed to the pier through the anchor groove formed in the center of each of the support and the support steel plate and then the unit through the connection hole formed in the center of the lower vertical plate Insert the bridge-raising bracket connecting rod to form a bridge-raising bracket integrating the unit bridge-raising bracket with nuts, and then attach the bracket to the connection hole of the supporting steel plate of the bridge-raising bracket installed on the side opposite to the connection hole formed on the upper side of the supporting steel plate. Interconnect with the connecting rods and install the jack support plate on the upper part of the connecting plate, and use the fixing bolt groove to fix the fixing bolts to complete the installation of the bridge lift bracket on the piers.

The unit bridge climbing brackets are installed in a plurality of shifts, and the "a" shaped support is installed on the upper part of the shift, and fixed to the shift through the anchor groove formed in the center of the support and the support steel plate with the anchor bolt to the lower number. Through the connecting hole formed in the center of the direct plate, the bridge rod bracket connecting rod is inserted to form a bridge bracket in which each unit bridge bracket is integrated with a nut, and then the upper end of the unit bridge is opposite to the connection hole formed in the upper portion of the supporting steel plate. After drilling the insertion groove in the alternating vertical part, insert the alternating connecting support bar inserted in the connecting hole of the supporting steel plate of the bridge lift bracket into the insertion groove formed in the alternating vertical part, and fixing the supporting steel plate and the alternating connecting supporting bar with a nut. After installing the jack support plate on the top of the connecting plate and using a fixed bolt groove fixed ball Fixedly connected to complete the installation of the bridge seungsang bracket to shift.

After the installation of the bridge ascending bracket on the shift and the pier is completed, install the jack on the jack movement prevention bar installed on the jack support plate, lift the bridge upper beam by the planned height by using hydraulic pressure, and then install the bridge beam. This is to complete the lifting of the bridge.

An object of the present invention is to mount the unit bridge lift bracket to the bridge and the bridge installation surface in order to increase the communication surface or the height of the bridge and the unit bridge installed on both sides of the bridge and the bridge by using the bracket connecting support rod After fixing the ascending bracket and connecting the multiple unit bridge brackets installed on one side of the bridge and the pier using the unit bridge ascending bracket connecting rod, the bridge is extended by raising the upper beam of the bridge by using the hydraulic jack installed on the jack support plate. And by reinforcing and installing a large number of small brackets to install the construction without affecting the convenience of work and existing shifts or piers to shorten the construction period and improve the convenience of construction.

In general, in order to expand or repair an existing bridge, as shown in FIG. 1, the support C is fixed to the pier and the bridge A using the anchor B, and then the bridge upper beam is raised using the jack to raise the bridge. Has been reinforcement. However, this method requires a lot of equipment to mount the support pole, because the bridge is heavy, and also requires a lot of manpower, so there is a problem of excessive construction cost and long construction period, another method is the upper part of the bridge Although the beam has been completely removed and then re-installed after the construction necessary for the raising of the bridge, this has also been a problem that the cumbersome construction cost and excessive construction cost are required.

The present invention has been proposed in view of the above, by installing a plurality of unit bridge lift brackets, connecting each unit bridge lift bracket using a steel rod, and using a method of lifting or repairing a bridge using a hydraulic jack. Since each unit bridge climbing bracket is small, it is lightweight and easy to install.It is very easy to install and does not require the use of separate heavy equipment even when connecting each other.It aims to provide a useful method that saves time for installation and dismantling. .
