A bridge structure using a factory-made socket member according to the present invention and a method of manufacturing a bridge structure using the same will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like or corresponding components Elements are denoted by the same reference numerals, and redundant description thereof will be omitted.

It is also to be understood that the terms first, second, etc. used hereinafter are merely reference numerals for distinguishing between identical or corresponding components, and the same or corresponding components are defined by terms such as first, second, no.

In addition, the term " coupled " is used not only in the case of direct physical contact between the respective constituent elements in the contact relation between the constituent elements, but also means that other constituent elements are interposed between the constituent elements, Use them as a concept to cover each contact.

Hereinafter, a bridge structure using a factory-made socket member according to an embodiment of the present invention and a method of manufacturing a bridge structure using the same will be described in detail with reference to the accompanying drawings.

The bridge structure of the present invention comprises a bridge 100; A socket member 200 coupled to an upper portion of the pier 100; A girder 300 which is inserted through the socket member 200; An alternation 400 for supporting both ends of the girder 300; And a concrete bottom plate 500 placed to be coupled to the upper portion of the socket member 200 and the upper portion of the girder 300 not inserted into the socket member 200.

The continuous ramen bridge is constructed as a fixed point (the point where the expansion and contraction of the girder is not possible) as the bridge pier, girder, alternation and girder are integrated.

In the case of continuous rayman bridge, the moment generated at the center part of the span and the moment generated at the bridge part (the focal point) are large.

However, when the socket member according to the present invention is used, the girder inserted into the socket member can be expanded and contracted along the longitudinal direction of the girder inside the socket member after the bottom plate concrete is poured.

In other words, since the socket member supports the girder that is mounted on the pier at the hinge structure (hinge point), it is possible to minimize the moment generated at the slope portion and the moment generated at the pier portion (see FIG. 16).

The socket member 200 includes a support 220 coupled to an upper portion of the bridge 100; And a lid part 240 coupled to the upper part of the receiving part 220 so as to enclose the side surface and the upper surface of the girder 300.

In this case, since the girder is installed inside the lid and can flow along the longitudinal direction of the girder, the girder coupled to the pier is supported by the hinge structure.

The receiving unit 220 includes a coupling unit 210 coupled to a lower surface of the receiving unit 220 to be fitted on an upper portion of the pier 100; And a rib 230 coupled to an outer surface of the coupling portion 210 and a lower surface of the receiving portion 220.

In this case, since the socket member is coupled to the top of the pier by the coupling portion, the socket member is easy to install.

The pier 100 has a steel pipe structure and the receiving part 220 is welded to the upper part of the pier 100 and connected to the outer surface of the pier 100 and the lower surface of the receiving part 220 .

In this case, welded joints are formed at the piers of the steel pipe structure by combining the upper part of the piers and the lower part of the piers.

The lid portion 240 includes a body portion 241 formed to surround the side surface and the upper surface of the girder 300; And a protrusion 242 protruding to the lower left and right of the body portion 241 and coupled to the upper surface of the receiving portion 220.

In this case, the lid portion is placed on the girder installed after the girder is installed, and the cover portion is easily installed because the upper surface and the projection portion of the receiving portion are bolted or welded.

Also, it is possible to prevent the conduction of the girder by installing the lid part.

It is preferable that a cross securing portion 243 coupled to the cross bar 310 is formed on one side or both sides of the left and right sides of the body portion 241.

In this case, since a cross beam is fastened to the main body in this case, a stable bridge structure can be secured.

The cross beam fastening portion 243 is formed to protrude from the center of the side surface of the main body portion 241 and is bolted to the abdomen of the cross beam 310 and the engaging plate 244.

In this case, the joining process is easy since the joining of the cross beams is performed by the bolts.

A guide bolt 221 is formed on the upper surface of the receiving part 220 and a longitudinal direction of the girder 300 is formed in a lower flange of the girder 300, It is preferable that a long hole is formed and coupled to the guide bolt 221.

In this case, since the girder is coupled to the guide bolt, the girder is stably coupled to the receiving portion without being conducted immediately after the girder is installed.

The shift unit 400 includes an alternate support unit 410 installed on the lower surface of the girder 300 to support the girder 300 in an upward direction; And a wall part 420 coupled to the outside of the shift support part 410 so as to protrude upwards to support the girder 300 in the inward direction.

In this case, the shift can be made at the factory as a PC (Precast Concrete), brought into the field and installed immediately.

The shift according to the present invention is a small shift in comparison with the existing shift, and is easy to install and transport.

A sliding pad 411 is preferably provided between the upper surface of the shift support portion 410 and the lower surface of the girder 300.

In this case, the lower surface of the girder is not damaged by the sliding pad in the case of the expansion and contraction due to the temperature.

A sliding bolt 412 is formed on the upper surface of the sliding pad 411 and a longitudinal direction of the girder 300 is formed in a lower flange of the girder 300, It is preferable that a long hole is formed and coupled to the sliding bolt 412.

In this case, since the girders are fixed by the sliding bolts after the alternate installation, the conduction is prevented.

It is preferable that an elastic member 421 is provided on the inner surface of the wall portion 420.

In this case, the stretchable material secures a space for the expansion and contraction of the girder, and prevents the end of the girder from being damaged when the girder is stretched or shrunk.

It is preferable that a cover plate 422 protruding inward of the wall part 420 is coupled to the wall part 420 so as to cover a part of the upper surface of the girder 300. [

In this case, when the bottom plate concrete is poured, the alternation and the bottom plate can be integrated.

The method for manufacturing a bridge structure according to the present invention includes the steps of installing a bridge pier (S100) for installing a bridge pier (100); An alternating step (S200) of installing an alternation (400); (S300) of joining a pedestal part (220) to a bridge pier (100); A girder installation step (S400) of placing the girder (300) on the support part (220); (S500) of joining the lid part (240) to cover the side surface and the upper surface of the girder (300); And a concrete pouring step (S600) for pouring the concrete to form the concrete bottom plate (500).

In this case, since the joining process of the support portion after the installation of the pier is easy and the lid portion joining step is performed after the girder installation step, it is possible to prevent the girder from being turned over without a separate girder turning prevention hole.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
