Description

Complex bridge

The present invention relates to a composite bridge design focusing on the aesthetic improvement of a bridge having a triple plane or double plane shuttle as a multi-lane bridge of four or more lanes.

The bridges are designed and constructed in accordance with the purpose and materials used, the location of the road surface, the planar shape of the bridge, the construction site, the bridge's function, the service life, the design load, and the structural type.

As the type of bridge according to the road surface position of the bridge is classified into Sangro Bridge, Haro Bridge, Middle Road Bridge, two-story bridge, and the structure of the bridge is the ramen bridge of Figure 2, the girder bridge of Figure 3, the truss bridge of Figure 4 , The arch bridge of FIG. 5, the suspension bridge of FIG. 6, and the cable-stayed bridge of FIG. 7.

The relationship between the position of the road surface and the structure type is as shown in the table below.The ramen bridge and the girder bridge can be installed as a vertical bridge, and the truss and arch bridges can be located at all road surfaces of the vertical bridge, the middle bridge, and the haro bridge. It is common to do

division deck bridge Middle school Haro Bridge Ramen ○ Girder bridge ○ Truss bridge ○ ○ ○ Arch bridge ○ ○ ○ Suspension bridge ○ Cable-stayed bridge ○

The bridge type of road bridges should be determined in consideration of functionality, stability, economics and aesthetics. The standard application site and girder height ratio (girder height / gear) for each bridge type depend on the design conditions. The table below shows the ratio between height of standard application and girder height according to past statistics.

table

One span of all bridges is a girder bridge if it is a girder bridge and an arch bridge if it is an arch bridge. The cable-stayed bridge has been constructed with the same road surface as the cable-stayed bridge.

Haro Bridge or Jungro Bridge is to build a bridge by installing a double plane main member on both sides of the bridge and connecting the cross beams to form a bottom frame to distribute the load.In the case of a multi-lane bridge with a wide width of the bridge, As this is so large and uneconomical, there are sarees constructed of triple or double-plane reciprocating bridges, as seen in the bridge of the type illustrated in FIG. 8 and the Tide Arch Bridge of the Han River Bridge. Depending on the location, the appearance of the bridge was awful.

The present invention aims to improve the aesthetics of an arch bridge in the form of a three-lane or double-lane shuttle bridge in the form of multi-lane or more.

The present invention is a four-lane or larger bridge that should be constructed in the form of an arch bridge cable-stayed bridge or suspension bridge of a triple or double plane shuttle bridge, and a suspension bridge of a halo bridge type in the middle separator section for separating two-way traffic from the center of the bridge width. It is a composite bridge that is very monotonous and refreshing by using a cable-stayed bridge or an arch bridge in the form of a middle and low bridge bridge. To provide.

A-da: Composite Bridge 1: Pylon

2: main cable 4: bottom frame

5: horizontal beam 6: vertical beam

7: high strength crossbeam 8: girder

10: center span 12: main member of the suspension bridge

13: continuous girder main member a: suspension bridge

b: 3 sequential cross section girder bridge c: both ends of bridge

The composite bridge (a) according to the first embodiment of the present invention shown in Figs. 9 to 13 constitutes a reciprocating bridge of a triple plane or a double plane of four lanes or more, the main cable at the upper center of the main column 1 (2) is hypothesized to be a single-plane self-supporting suspension bridge (a) in the form of supporting the centerline portion of the bridge superstructure (3), and on both sides of its distal ends in the form of a three-step continuous cross-sectional girder bridge (b). (5) and the stringer (6) is connected to form a composite bridge to form a bottom frame (4), but the girder (8) by installing a reinforced high-strength crossbeam (7) at both ends (c) of the start and end of the bridge Is a composite structure type configured to exert a function of a compression member corresponding to the tension of the main cable (2).

The composite bridge (b) according to another embodiment of FIGS. 14 and 15 is an arch-shaped composite bridge that emphasizes beauty by changing the center span 9 of the composite bridge (a) according to the first embodiment into an arch shape.

16 and 17 of another embodiment of the present invention (C) is installed in the main section 10 of the suspension bridge in the center separator section and the main arch arch 11 in both sides of the same span bridge, bi-directional bridge It is a composite bridge in the case of construction through the method of forming the bottom frame by connecting the cross beams of both planes after installing the main member 12, the continuous girder main body 12 in the center of the.

As described above, the composite bridge of the present invention is very economically applicable when applied to multi-lane long-span arch bridges with wide widths of roads, and also provides a bridge structure with beautiful views of the bridges, as well as cables such as cable-stayed bridges and suspension bridges. It can be built as a strong bridge by increasing the resistance to wind, the most vulnerable element in the bridge.

Above all, this composite bridge has a very good aesthetic effect on arch bridges and suspension bridges.
