Description

High level structure having hybrid closed section

The present invention relates to an expensive structure having a hybrid closed section.

The bridge comprises a girder supporting a top plate and a top plate for the passage of vehicles or pedestrians. At this time, the girder is a single or plural pieces are arranged side by side in the longitudinal direction of the bridge to support the top plate, the material of the girder is mainly used steel or concrete, and in some cases, a combination of steel and concrete is used.

On the other hand, there are an increasing number of cases where various structures or structures, such as railings and soundproof walls, are installed on the bridge deck for the purpose of improving functionality, aesthetics, or stability. All of these structures and structures are non-structural, and do not function at all as a structure that shares the load acting on the bridge and transfer the load to the bridge. Due to this, the size of the girder used in the construction is gradually increasing to ensure the structural stability of the bridge, which makes the construction itself difficult and increases the cost.

In the installation of a conventional bridge, there was a cylindrical bridge type of closed section without using a girder.

1, 2, and 3 show perspective views of a conventional truss bridge (US 2011/0047722 A, US 5680664 B). As shown in Figures 1, 2 and 3, it can be seen that the truss-type cylindrical bridge is shown. 4 is a partial cross-sectional view of a conventional composite truss bridge (KR 2012-0030481 A). 5 is a perspective view of a conventional composite circular truss bridge (KR 1635523 B). As shown in Figure 4, it can be seen that the structure of the truss bridge using a steel pipe for the abdominal member in the form of a composite truss bridge, and concrete for the top and bottom chords is described. As shown in FIG. 5, it can be seen that a truss hole is formed in the cylindrical steel girder, so that there is a bridge through which a vehicle or a person moves.

It can be seen that there exist a bridge using a cylindrical structure of a conventional closed section, and a truss bridge in the form of a mixture of concrete and steel. There is a bridge in which a steel disk having a circular cross section is disposed in the longitudinal direction and connected between the steel disks with a connecting member. In addition, it can be seen that there is a bridge in the form of moving vertically by installing a vertical beam in the longitudinal direction and winding the hoop-like member into a tube shape.

However, in manufacturing a girder, a hybrid girder is made of concrete and steel to form a girder using heterogeneous materials, or a truss-type girder bridge using heterogeneous materials using steel materials for abdominal members in a truss type bridge. As a result, the upper and lower chords are made of concrete members, which are not made elastically depending on the stress of the entire bridge.

There have been various types of cylindrical bridges without installing girders, and composite circular truss bridges are large steel pipes that are manufactured by forming truss holes on the sides of cylindrical steel girders. As it has to be moved, there is a problem that only a small sidewalk bridge is possible due to various constraints when moving.

Truss bridges can be produced in the field by arranging disk shapes in the longitudinal direction and connecting them, but there is a problem in large bridges because stress concentration can occur due to inconsistent shapes, install vertical beams and wind up hoop-shaped members Produced in the form of a tube that maintains its shape is also a problem with stress, and thus is not suitable for large bridges.

In addition, for long-span bridges with long spans, there are bridges using truss-type girders rather than cable-stayed bridges or suspension bridges, but hybrid composite structures of closed cross-sections that can efficiently utilize and economically use cross-sections are not possible.
