Problems solved by technology

However, due to the high-altitude operation, the construction risk of concrete support is high, so the concrete bridge deck needs to be prefabricated in the factory and installed on site, which is inconvenient for construction
Moreover, the connection between concrete and section steel is unfavorable in force, poor in integrity, and prone to later diseases

Embodiment Construction

[0034] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as Figure 1-4 As shown, a composite deck system of profiled steel plates for a pedestrian suspension bridge includes steel structure stiffening beams 103, and the steel structure stiffening beams 103 are composed of multiple beams 102 arranged in parallel and two or more longitudinal beams 101. The fixed connection between the beam 102 and the longitudinal beam 101 forms a stiffened beam frame structure 106; the top of the beam 102 and the longitudinal beam 101 are located on the same level, and the exposed area surrounded by the beam 102 and the longitudinal beam 101 is laid with a profiled steel plate 201 The edge of the profiled steel plate 201 is connected with the beam 102 or the longitudinal beam 101; the profiled steel plate 201 is cast with a reinforced concrete bridge deck 202 in place.

[0036] The number of crossbeams 102 and l...

Abstract

A profiled steel sheet combined bridge deck system of a pedestrian suspension bridge comprises a steel structure stiffening beam, the steel structure stiffening beam is formed by combining a pluralityof cross beams arranged in parallel and two or more longitudinal beams, and the cross beams and the longitudinal beams are fixedly connected to form a stiffening beam frame structure; the tops of thecross beams and the tops of the longitudinal beams are located on the same horizontal plane, profiled steel sheets are laid in exposed areas defined by the cross beams and the longitudinal beams, andthe edges of the profiled steel sheets are connected with the cross beams or the longitudinal beams. A reinforced concrete bridge deck slab is cast in place on the profiled steel sheet; compared withthe prior art, the profiled steel sheet has advantages that the stress is safe and reliable, bearing capacity is high, integrity of a bridge floor structure is enhanced, construction is convenient, and economical efficiency is good.

Description

technical field [0001] The invention belongs to the technical field of pedestrian suspension bridges, and in particular relates to a profiled steel plate composite deck system and a construction method for pedestrian suspension bridges. Background technique [0002] Pedestrian suspension bridges are widely used in mountainous bridges due to their large spanning capacity and good landscape experience performance. Among them, the suspension bridge deck system, as the main component of the pedestrian suspension bridge, is in direct contact with pedestrians, bears the load of the crowd, provides local stiffness, prevents excessive deformation of the bridge deck, and ensures the comfort of pedestrians crossing the bridge. It is the key to the design of pedestrian suspension bridges. [0003] At present, the deck system of pedestrian suspension bridges generally adopts the form of laying steel plates, wooden boards or concrete slabs on lattice steel. This type of bridge deck syst...
