200 Panel Prefabricated Temporary Truss Arch Bridge Structures

Steel Truss Bridge Temporary Bridge Structures Truss Arch Bridge

Steel truss bridge is a down-through steel truss bridge that can be used for permanent or semi-permanent bridges. The bridge consists of the main truss, the deck system, the connection system, the bridge foundation and the bridge's auxiliary structures. Bridge decks are generally in the form of reinforced concrete panels and asphalt concrete paving. Compared with the solid web beam, the sparse web beam is used to replace the overall web, thereby saving steel and reducing the weight of the structure. Because the amount of steel in the web beam is less than that of the solid web beam, the steel truss can be made larger height, which has greater rigidity and greater spanning ability.

Introduction
Steel Truss Bridge is a standard bridge equipment, adopted extensively and the most popular in the world.

Features
1. Steel Truss Bridge is easy to repair and replace,long lifetime,material can be recycled.

2.Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make steel bridge in the working condition and calculation compared with the assumption
3.Steel Truss Bridge generally USES factory, site splicing, the construction period is short, processing convenient and not affected by seasonal effect.
4. Steel Truss Bridge is suitable for industrialized manufacture and very convenient to transport.

5.High strength and big stiffness , relative to the concrete bridge can be reduced trabecular high and self-respect

Competitive Advantage:

Application
Beam bridge,arch bridge,rigid frame bridge,cable-stayed bridge,suspension bridge. passenger foot-bridge

Mixture form to erect all kinds of
The compact 200 panel bridge: The compact 200 panel bridge is similar to the compact 100 panel bridge from their appearance. The difference is its increased panel height to 2.134m. It employed the method of alternating joints between Reinforcement Chords and the joints between panels. This method can decrease inelastic deformation caused by the oversized pinholes.

Bolt-connected components use the orienting sleeve- fixing method to increase accuracy of connections. Shear is created in orienting sleeves and tension is developed in bolts, which increase the usage life of the bolts and ensure the safety of panel bridges. Wind resistant brace is made to be composite type and is connected to transom/girders to improve overall stability of panel bridges.

Pre-arch method is used to additionally cut down mid-span and vertical deflection to a larger degree.

Temporary Bridges, Emergency Bridges and Fixed Bridges.
Using the bridge equipment, the suspension bridges of varied span can be erected.
The bridge has the advantages of few components, light weight and low cost.
Bailey Bridge requires no special tools or heavy equipment for construction, the bridge elements
are small enough to be carried in , and the bridge is strong enough to carry . It is considered a great example of military engineering.
