The top of the transverse distribution beam of two steel trestle buttresses, office are at the both ends of the transverse distribution beam along bridge to respectively setting one group of shellfish thunder
Beam；Clamping sleeper beam is provided with the brace point of intersection of the Bailey beam；Crossbeam is set on the clamping sleeper beam, using crossbeam two
Direction across bridge connection is carried out between group Bailey beam；Along bridge to some groups of longitudinal support beams are set on the crossbeam, in the longitudinal direction
The top surface of support beam lays checkered steel plate as bridge floor.
The design feature of the utility model Bailey beam steel trestle is lain also in：In the steel trestle buttress, longitudinally adjacent
Two steel pipes between, and be respectively arranged between two laterally adjacent steel pipes connection system, the connection system is vertically
It is arranged at intervals multigroup.
The design feature of the utility model Bailey beam steel trestle is lain also in：The clamping sleeper beam is a pair of opposite grooves of notch
Steel, the pair of channel-section steel are clamped in inside and outside a piece of beret truss brace intersection point, carried out between a pair of channel-section steels using bolt
Connection.
The design feature of the utility model Bailey beam steel trestle is lain also in：Pass through U-shaped spiral shell between the crossbeam and Bailey beam
Bolt is fixed.
The design feature of the utility model Bailey beam steel trestle is lain also in：Single group longitudinal support beam is welded using make-up channel-section steel group
Part, longitudinal spandrel girder, transverse distribution beam and crossbeam use I-steel or H profile steel.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model is reasonable in design, using the Bailey beam of existing structure and the construction features of shaped steel, using wound
New structural arrangement form, clamping sleeper beam is set in Bailey beam brace point of intersection, meets the installing space of high cross bearer simultaneously
Reduce installation difficulty；Using base-supporting structural arrangement form, bridge deck width and span are increased, improves the current of steel trestle
Ability.
2nd, the utility model is simple in construction, and peace is torn open easy to operate, and construction speed is fast, and whole structural stability is good and safely can
Lean on.
