Description
The present invention relates to temporary bridges that are temporarily installed for temporary bridges or construction, more specifically, it is possible to easily implement prestressing, easy installation of prestressing steel wire, and connect a plurality of supporting files simply and stably. It is related with the temporary bridge using the prestressing steel wire which can be installed and can finish both ends of a temporary bridge compactly and stably.
In general, bridges are constructed and used for transportation between one branch and another branch or for various other purposes. On the other hand, temporary bridges are installed temporarily or semi-permanently for the passage of construction vehicles and workers or the public, or for the rapid installation of bridges in addition to such permanent bridges.
Such a temporary bridge can be constructed by first connecting a beam or using a concrete to install a temporary vent or piers on the ground, then connecting several beams on the top of the temporary vent or piers to integrate them, and then installing a perforated plate on the joint. have. And there is a method of introducing prestressing using a high-strength steel bar and a method of assembling the truss continuously and repeatedly.
However, in the conventional bridges applied with high-strength steel rods, the distance between the vents and the vents is slightly longer and the offset of the stress is slightly increased, but the beams of the temporary bridges are liable to be weakened or are vulnerable to vibration. In severe cases, there was a problem of breaking the rod.
On the other hand, various embodiments have been proposed as a solution for solving the conventional problems as described above, for example, Korean Patent Laid-Open Publication No. 2003-0086222 discloses the upper and lower flanges of the upper H beam and the lower H beam having different rigidity from each other up and down The connected double beams and the double beams are installed on the support box installed on the temporary vents using pre-stressed composite prestressed with hydraulic jacks on the workbench, and the upper H beam, double beams, and prestressed composite doubles according to the stress distribution on the temporary bridge. Although a temporary bridge having a structure for installing and connecting beams has been proposed, this publication discloses that the addition of double beams is expected to have some effect on beam stiffness, deflection, and vibration, but the addition of double beams and their excessive weight make pier bridges. Or the construction of the temporary vents is not only complicated but also the increase in the distance between the piers or the temporary vents In the course of this addition process is complicated and takes gyeopbo the transitional period, there is the problem that caused the rise in costs.
In addition, Korean Patent Registration No. 10-392679 and Utility Model Registration No. 20-358339 each have a steel member, a pair of fixing parts mounted on both ends of the steel member and formed at a predetermined height from a lower surface of the steel member, It consists of a tendon fixed through the lower side of the pair of fixing parts so as to be parallel to the steel member, and a biasing member mounted to the center of the lower surface of the steel member and formed to have a height not greater than the height of the fixing part. When the steel member is prestressed and deflection of the steel member occurs, a structure is proposed in which the deflection member contacts the tendon and transmits the upward vertical force by the tendon to the steel member. When generated, the stress can be dispersed by the action of the biasing member and tendon to maintain a somewhat stable state, but these proposals also show Since all the ashes must be directly fixed to the pier or temporary vents, the structure of the pier or temporary vents is not only complicated, but the distance between them can not be increased by a certain length, and thus workability and safety are still deteriorated. . In addition, the pre-stressing is applied to the fixing parts separately installed on both sides of the lower end of the beam, causing unnecessary problems that hinder safety, as well as having to install such fixing parts separately, there is a complicated problem of manufacturing and construction.
On the other hand, concrete piles for the composite pile of Patent No. 10-0803658 for the installation of the piers, hollow concrete piles, connecting steel pipes installed to cover at least a portion of the upper side of the hollow concrete piles, and the connecting steel pipes of the hollow concrete piles An end plate coupled to the installed top surface, a coupling part for coupling the connection steel pipe and the hollow concrete pile, and a tensile steel wire installed in the longitudinal direction of the hollow concrete pile; The coupling part is configured in such a way that one edge is fixed to the inner circumferential surface of the connecting steel pipe and the other edge is fixed to the end plate, and is variously installed on the ground of the lower part of the piers by driving or pre-excavation. Although it supports, when a plurality of concrete piles for the composite pile are interconnected by the worker directly bolted or welded, there is a problem that the work speed is delayed as well as causing a safety accident, depending on the skill of the operator There is a problem that can not be kept uniform.
Therefore, the present invention has been invented to solve the above-described problems, the object of the present invention can be easily implemented pre-stressing, easy installation of pre-stressing steel wire, can be connected and installed a plurality of support files simply and stably In addition, the present invention provides a temporary bridge using prestressing steel wires capable of compactly and stably finishing both ends of the temporary bridge.
