Abstract
The present invention relates to a tension device for a temporary bridge capable of re-tensioning and detachment using a carbon plate, which is useful for demolishing a temporary bridge because the tension of a carbon plate is maintained and a cylinder for tensioning the carbon plate is detachably mounted.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tension device for a bridge, more particularly, to a tension device for tensioning a carbon plate and a cylinder for tensioning a carbon plate are detachably mounted, And a tension device for a temporary bridge capable of attaching and detaching.
Many temporary bridges are to be constructed with the intention of temporarily bypassing vehicles or traffic or constructing direct construction sites in the construction of permanent bridges or other works.
Currently, the installation method of bridges is to connect the beams to each other to form a temporary vent, and then weld them together with the temporary vent to install a temporary bridge, and then install a floor plate or an iron plate thereon, A conventional method, a method of introducing a prestress using a high-strength steel bar, a method of continuously assembling a truss, and a method of assembling a steel material incorporating a prestressed steel.
Recently, a method using prestress carbon plate and a tension material is mainly used.
However, the above method is not economical because it can not tear and re-tension the carbon plate for subsequent maintenance, and can not remove or re-install the tension device. In addition, when the temporary plate is demolished, There was a problem to be done.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a carbon plate, which is useful for maintaining tension after a tension of a carbon plate and detachably attaching a cylinder for tilting the carbon plate, The present invention also provides a tension device for a temporary bridge capable of re-tensioning and detaching and attaching.
A tension device for a temporary bridge capable of re-tensioning and detachment using a carbon plate according to the present invention,
A plurality of H beams longitudinally installed on bridge columns of the temporary bridge;
A fixing table fixed to an upper portion of one side of the H beam;
A moving element fixed to an upper portion of the H beam on the other side of the fixing table and moving along the rail;
A reaction force band fixed to the H beam between the fixed member and the movable member;
A carbon plate having one end coupled to the fixing table and the other end coupled to the moving element;
A wedge for fixing the carbon plate to the fixing table and the moving element;
A cylinder mounted between the moving element and the reaction force band to tense the carbon plate while moving the moving element;
And a tension controller mounted inside the cylinder between the moving element and the reaction force band to maintain or release the tension of the carbon plate.
According to the tension device for a temporary bridge capable of re-tensioning and detachment using the carbon plate of the present invention, since the tension for maintaining the tension of the carbon plate and the cylinder for tilting the carbon plate are detachably mounted, the removal of the temporary bridge is advantageous and safety is secured It is.
