Embodiment Construction

[0022] Such as Figure 1-Figure 4 As shown, it is the structure of the multi-beam non-longitudinal high-speed railway orthotropic slab integral steel deck 1 of the present invention. Beam joints are arranged at regular intervals at the nodes of the main truss and on the members of the chord 2. The joints are divided into bridge deck joints 3 and beam bottom plate joints 5. The bridge deck joints 3 form a joint where the top plate 21 of the chord 2 protrudes from the vertical plate 22 of the chord 2 and is used to connect the main truss and the bridge deck 6. Top plate 21 intersects with gusset plate at the joint when stretching out vertical plate 22, and slots shall be opened at the corresponding gusset plate position to allow it to pass through, and then be welded around the arc end periphery of gusset plate. The crossbeam bottom plate joint 5 is a section joint extending the bottom plate 23 of the chord 2 out of the vertical plate, and the crossbeam web joint 4 is directly w...

Abstract

The invention discloses a multi-beam non-stringer high-speed railway orthotropic slab integral steel deck construction, comprising a main truss, a beam and a bridge deck, wherein the bridge deck is a integral steel plate, one beam connector is fixed on a node of the main truss and a chord member on every certain distance, the beam connector connects the bridge deck and the beam integrally, longitudinal stiffening ribs is fixed on the bridge deck. The steel deck construction of the invention has no stringer, the deck construction only has connection between the beam, main truss and the ribs, and has no complex stringer and beam connector, thereby simplifying deck construction, manufacturing conveniently, installing simply, reducing examining and maintaining workload in later stage, and having good bridge deck integrity.

Description

technical field [0001] The invention relates to a high-speed railway orthotropic plate integral steel bridge deck in the field of bridges. Background technique [0002] The bridge deck refers to the structural system of the bridge superstructure that directly bears the loads of vehicles and crowds and transmits them to the main load-bearing components. The bridge deck system is a very important part of the bridge structure. [0003] Steel truss girders have been used in bridge structures long ago. For decades of development, the bridge deck structure has always been a bridge deck structure dominated by longitudinal and horizontal beam systems. The vertical and horizontal beam structure is to set up beams at the joints of the trusses to connect the main trusses horizontally, and set up longitudinal beams between the beams parallel to the direction of the chords. The vehicle load is transmitted to the beam through the longitudinal beam, and the beam is connected to the node t...
