A guide rail beam (10), a track beam unit (100), and a track beam (1000) for a rail vehicle (7) are disclosed. The guide rail beam (10) includes a fixing plate (1), a flange plate (2), a web plate (3), and a stiffening rib (5). The fixing plate (1) is disposed on a mounting surface (20). The flange plate (2) is disposed above the fixing plate (1). A road wheel (71) travels on the flange plate (2). An upper end of the web plate (3) is connected with the flange plate (2), and a lower end of the web plate (3) is connected with the fixing plate (1). The web plate (3) is in contact with and be associated with a guide wheel (72) to guide a traveling track of the guide wheel (72). An upper end of the stiffening rib (5) is connected with the flange plate (2), and a lower end of the stiffening rib (5) is connected with the fixing plate (1).

Bridge systems and methods for constructing bridges having overhang surfaces employing generally rectangular, precast, prestressed concrete panels. One method includes delivering a plurality of generally rectangular, precast, prestressed concrete panels to an installation site, and delivering one or more support beams to the installation site, each support beam having a support and a base. The concrete panels are positioned on the supports of the one or more support beams with an overhang panel section and a traffic panel section. The concrete panels are then connected to the support beams by positioning steel reinforcement in block outs or voids, pouring unsolidified concrete into the voids, and curing the unsolidified concrete to form an overhang traffic surface. Bridges constructed employing the precast, prestressed concrete panels and methods. Other bridge systems employ prestressed concrete L-walls and double-T members, where weight-bearing L-walls have pockets for webs of the double-T members.

“A method for producing a construction section of a deck slab for a bridge includes the following operations: producing a bottom layer composed of a segment and having cross beams, which are arranged in the transverse direction in regard to the longitudinal axis of the longitudinal bridge girder, from reinforced concrete; transporting the bottom layer having the cross beams for a construction section of the deck slab using a conveyor device from an assembly site to an installation site and lowering it into the installation position; producing a top concrete layer for a construction section of the deck slab on the bottom layer; removing the bottom layer having the cross beams for a construction section of the deck slab from the conveyor device and moving the conveyor device away from the installation site.”

A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.

Provided is a viaduct structure. The viaduct structure consists of steel bridge columns, steel plate girders, a bridge deck bottom steel plate, bridge deck side steel plates and cement-gravel concrete, where the steel bridge columns, the steel plate girders and the bridge deck bottom steel plate are welded to one another to form the ceiling type steel architecture, the bridge deck side steel plates are welded to the bridge deck bottom steel plate, and the cement-gravel concrete is poured in a groove-like structure formed by the bridge deck side steel plates and the bridge deck bottom steel plate. The viaduct structure has the advantages of a firm structure, a thin bridge deck, the thin steel plate girders, a low height of the bridge deck, no plywoods required for pouring, convenient construction, low waste, a low material consumption, a low construction cost, a short construction period, etc.

A climbing inhibition system for inhibiting a person from vandalizing a bridge includes a bridge that has a lateral surface. The lateral surface has a ledge extending outwardly therefrom. A wedge is coupled to the lateral surface of the bridge. Thus, the wedge may inhibit a person from gaining a foothold on the ledge thereby inhibiting the person from defacing or vandalizing the lateral surface.

A bridge or other construction comprising a deck, in which the deck is designed to be lightweight and durable, such as by including aluminum, and readily installable on a main bearing structure of the bridge or other construction (e.g., without welding and/or without drilling or otherwise creating holes into the main bearing structure of the bridge or other construction), even if the main bearing structure of the bridge or other construction is based on different material (e.g., steel).
