BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-span integral bridge bridge using a PC beam and a seismic reinforcement shear block structure of bridge bridges, and particularly, in order to prevent the bridges and bridge bridges from falling in the lateral direction due to earthquake resistance. The present invention relates to a shear block structure having a great restraint force against a perpendicular displacement and having excellent stability and construction ability and very easy to install.

In the conventional seismic design concept of small and medium bridges, the method of using fixed and special bearings is mainly applied, and the method using these bearings requires various types of bearings according to the conditions, and thus construction also requires a lot of work. To be done.

In addition, fixed bearings used in bridge piers of existing bridges require more precision than bidirectional free end bearings in construction, and constrain the inherent movement of the bridge to fixed bearings when displacement of the bridge occurs due to temperature changes. Compared with the installed case, there was a problem that high stress is generated in the bearing member.

In addition, since the terrain of the mountains and valleys is complicated and the high and low phenomena are severe in Korea, seismic design using fish beams and stability of structures are required.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to improve stability by increasing the restraint force against the displacement of the axial direction and the perpendicular direction of the axial axis when constructing an alternating bridge or high cost using a PC beam of two or more spans. It is to provide a multi-span integrated bridges using a PC beam that can be made and expensive earthquake-resistant reinforced shear block structure.

It is another object of the present invention to provide a shear block structure that suppresses the collapse by seismic utilization by maximizing the characteristics of the bridge structure in the integral bridge bridge or high / medium bridge construction.

The present invention for achieving this object is a multi-segment integral bridge bridge and a high-precision PC beam (PC Beam) and a bearing installed on the pier foundation concrete and two or more installed PC beam (PC Beam) and Fixed to increase the binding force between the axial direction and the axial direction displacement between the PC beam; A shockproof reinforced shear block structure was achieved by consisting of a side plate secured by an anchor on both PC beam surfaces, a main body portion formed with a threaded line coupled with an external threaded adjustment rod, and a shear block structure composed of an adjustment lever. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings of preferred embodiments of the present invention.

Both side plates 20 and 20 'fixed to an anchor on both sides of the PC beam, and the side plate is coupled to the other side, but the other side has a left support 60 having an external male thread formed thereon, and a length to be coupled to the left support. A female thread is formed inside the control lever 70 and installed as a shear block structure 120 including a right support 80 coupled to a side plate to throttle between a PC beam and a PC beam. There is a feature that is constructed to increase the restraint force in the direction and the displacement perpendicular to the axial axis.

Although the PC beam is a reinforced concrete structure, it is used for high prices of alternating bridges and general roads, but in order to prevent the loss of life and property due to the occurrence of shaking or falling due to the earthquake and impact from the outside. It is.

The shear block structure unit 120 installed between the two or more PC beams fixes the side plates 20 and 20 'fixed to the anchor beams 10 on both sides of the PC beams. The left support 60 was fixed to the plate and formed with an external male thread.

The left support 60 and the right support 80 is coupled to the connection is characterized in that the length adjustment lever 70 in front of the right support to adjust the length.

The right support 80 is characterized in that the left support 70 is formed so that the length can be adjusted by forming a through hole so that it can enter.

As shown in FIGS. 2 and 5, in another embodiment of the present invention, the shear block structure 120 is fixed to both sides of the PC beam so as to slide laterally on both sides of the PC beam. It can be installed in the desired position or required position in the construction by constructing the "" -type rail portion 90 and the side plate (20, 20 ') is inserted in the rail portion so that the shear block structure can move in the transverse direction. It was made.

4 and 5, the multi-span integrated shift bridge using the PC beam and the expensive shockproof reinforced shear block structure according to another embodiment of the present invention shown in FIGS. 4 and 5 are side plates mounted on both sides of the PC beam. By installing and installing the shock absorbing member 50 including the spring 30, the adjusting nut and the bolt 40 at the connection portion of the 20, 20 'and the left and right support parts 60, 80, the earthquake, vibration and thermal expansion There is a feature constructed to have a buffer so as to absorb the displacement.

Multi-span integral bridges and expensive earthquake-resistant reinforced shear block structures using the PC beam of the present invention are constructed as described above by turning the length adjustment lever 70 after the installation of the PC beam. On the contrary, it is reduced by turning it so that it is possible to adjust between PC beams, making construction easier.

Referring to the operation of Figures 2 and 5 of another embodiment of the present invention; The shear block structure portion 120 has a side plate on the rail portion after installing a "c" type rail portion 90 fixed to both sides of the PC beam so as to slide laterally on both sides of the PC beam. (20, 20 ') is inserted is characterized in that the construction so that the shear block structure can move in the transverse direction.

By constructing as described above, the PC beam is fixed to one side of the "c" type rail part 90 so that the front block structure part 120 is mounted so that it can be mounted in a desired position, especially when used in a region where a large cross bridge is large. The shear block structure 120 is slid so as not to affect the structure during the transverse deformation.

The multi-span integrated bridges and the expensive earthquake-resistant reinforced shear block structures using the PC beam protect people and property by preventing shaking and domino phenomenon of the structures due to earthquakes when used in multi-span bridges. In particular, the effect is maximized when it is used for the elevated price of the inner main road.
