Description
Technical field
The utility model relates to field of bridge construction, and in particular to a kind of steel truss assembly lock head shellfish Lei Gangqiao.
Background technique
With the development of China's construction of hydropower facilities cause, the Construction of Step Hydropower Station of most of rivers has extended to upstream, engineering
Place many places in mountain area that is with a varied topography, having inconvenient traffic, based on the sidewalk of marching into the arena of Engineering Service also multispan gets over what The turbulent river crashes its way through
Rivers.In certain ship lock reconstruction and extension projects, for the ease of being open to traffic and improving construction efficiency, need that Bailey bracket is arranged in lock head
Bridge connects ship lock left and right banks, to extend construction road to each operation side.
Currently, being set up after conventional Bailey bridge is mainly assembled at the scene using outstanding pushing manipulation, i.e., first installed on the abutment of two sides
The rolling of rock and roll peace, by bridge member, to roll on progress assembled flat, then uses manpower or mechanical traction, by bridge it is steady and slowly
It releases, go directly opposite bank rock and roll, then removes section by section again, falls bridge positioning.Therefore, control stress point when erection, which is ensuring that, releases side
The shearing of truss, moment of flexure are no more than its corresponding feasible value at rock and roll, and the tilting moment for guaranteeing that outstanding part generates outside truss is less than
The stabilizing moment that the non-outer outstanding part of truss generates, avoids pontic from tumbling in push.As it can be seen that Bailey bridge truss itself
The shearing strength of structure plays the role of vital shearing strength especially at connecting node.However, existing Bailey bridge
Pin is only used between the male and female head of unit beret slice in assembly or is bolted, and belongs to weak part, or in unit shellfish
The lower boom of thunder piece is additionally arranged at the bottom of reinforcement chord member, but does not play snap action, therefore the node strength of Bailey bridge and antidumping energy
Power is still to be improved.
