The Bailey beam is a truss beam composed of the Bailey frame, which is mostly connected by lattice windows, and then fixed with bolts. Bailey beam is convenient and fast in engineering construction, such as the gantry crane, the construction platform, engineering sidewalk bridge, etc.
Bailey steel bridge originated in Britain, is the British Donald Bailey engineer invented in 1938 during the second world war, in the early 1960s began to produce prefabricated highway steel bridge 321 highway steel bridge, bay steel bridge is a simple structure, lightweight, convenient transportation, but also has large carrying capacity, structural rigidity, long fatigue life, mainly used in military transportation, rescue and disaster relief, national defense construction, water conservancy engineering, road traffic and other fields.
The reinforcement method of Bailey steel bridge is very important. The steel reinforcement method refers to the reinforcement bond of the coagulation contact surface and the steel plate as a major key point in the construction process. When the dry environment reinforcement method is adopted, the shape of the concrete is smooth, and can not have any debris. If the wet environment reinforcement mode is used, chemical methods should be used, grouting, and dust removal and cleaning with chemicals. The external adhesive steel consolidation method of component refers to the chemical method of dust removal on the surface of the Bailey frame, cleaning up the rust or impurities above, select the adhesive, adjust to the prescribed proportion, and reinforce the steel plate after mixing evenly. Prestress method refers to the use of prestressed steel bar, adding prestress to the steel bar, through bolt reinforcement, to balance the tensile stress of the steel plate.
