Abstract
The invention discloses a bailey beam hinged support and belongs to the technical field of bridge engineering. The bailey beam hinged support comprises lug plates, stiffening plates, a bottom plate and lengthened bailey pins. The bottom plate is a rectangular plate. The lug plates are wipe-corner rectangular plates and are provided with pin holes matched with the lengthened bailey pins. The two lug plates are welded to the two ends of the bottom plate vertically and perpendicularly. In order to ensure the stability of the lug plates, the lug plate stiffening plates are arranged, are welded to the bottom plate and are located on the outer sides of the two lug plates; and lower chord female and male connectors of two bailey beams are located between the two lug plates and are aligned at the pin holes in the lug plates, and the lengthened bailey pins penetrate through the pin holes for fixation. The bailey beam hinged support is used, thus downward sliding force of an upper structure and automobile braking force can be effectively transmitted to a lower structure, the effect that the downward sliding force transmitted by the upper structure can be transmitted to the lower structure in time at any time is ensured by a lengthened hinge pin, the lug plates and the bottom plate, and the problems that a traditional wedge block cannot transmit horizontal force and a bailey beam can only be erected horizontally are solved. The adaptability is high, recycling is achieved, and assembly is convenient.
Description
Technical field
The invention belongs to technical field of bridge engineering, is related to interim Bailey beam trestle and sets up, heavy grade is related specifically to
A kind of Bailey beam hinged-support of trestle.
Background technology
Bridge pad is arranged between the superstructure of bridge and pier, and its effect is by the various loads on bridge span structure
Counter-force is delivered on pier, while ensureing displacement and rotation required by bridge span structure.
Traditional trestle and operation platform is level erection.But in some occasions, stress place limits, and trestle is haveed no alternative but
Inclination is put, so as to reduce floor space.The power downward along slope produced because inclination is put is just inevitable, if ignored
The presence of sliding force, will produce great potential safety hazard to the security of structure.
Traditional wedge solves the problems, such as that the ability of the gradient is substantially not enough：1. bad adaptability, need to set according to different gradient
Different wedges；2. sliding force ability is transmitted, and wedge can be welded effectively with lower section distribution beam, but its shellfish with top
Thunder beam cannot be welded.(Bailey beam chord member material is 16Mn, and its Weldability is poor, considers that it is recycling rod member in addition, also not
Allow welding).It is domestic at present to there is no simple, feasible method for heavy grade Bailey beam sets up.
The content of the invention
The invention provides a kind of Bailey beam hinged-support, using this bearing, can effectively transmit the downslide of superstructure
Power, and it is easy for installation, adapt to gradient ability strong.
Technical scheme：
A kind of Bailey beam hinged-support, it effectively overcomes sliding force, and sliding force is reached into the bearing of substructure, including ear
Plate, stiffener, base plate and lengthening Bei Leixiao；Wherein, base plate is rectangular slab, and otic placode which is provided with cooperation and add to smear angle rectangular slab
The pin-and-hole of long shellfish thunder pin, two otic placodes are vertically vertically welded in the two ends of base plate；To guarantee otic placode stability, added by arranging otic placode
Strength plate, otic placode stiffener is welded on base plate, positioned at two otic placodes outside；The lower boom negative and positive head of two panels Bailey beam is located at two otic placodes
Between, and align with pin-and-hole thereon, lengthen shellfish thunder pin and be fixed through pin-and-hole.
Base plate according to circumstances carries out weld all around with the connection of substructure or crab-bolt is fixed.
Bailey beam hinged-support strong adaptability, and remain floor level.No matter Bailey beam in which kind of inclination angle (14 ° with
It is interior), can adopt the hinged-support.
The Bailey beam hinged-support is not required to produce existing finished product Bailey beam punching destruction, effectively solving sliding force problem.
Lengthening shellfish thunder pin adopts 30CrMnSi, other parts steel to adopt Q235 or Q345 materials.
The invention has the advantages that：Using this bearing, sliding force, the automobile system of superstructure can be effectively transmitted
Power to substructure, by plus long pin shaft, otic placode, base plate ensure the sliding force of superstructure transmission at any time can and
When be transferred to bottom, solving " traditional voussoir " can not transmit horizontal force, and Bailey beam can only the problem that sets up of level.Bailey beam is cut with scissors
Bearing strong adaptability, repeats and utilizes, easy to assembly.
Description of the drawings
Fig. 1 is that hinged-support is longitudinally arranged figure.
Fig. 2 is hinged-support lateral arrangement figure.
Fig. 3 is hinged-support facade structural map.
Fig. 4 is to lengthen shellfish thunder pin drawing.
In figure：1. otic placode；2. stiffener；3. base plate；4. Bei Leixiao is lengthened.
Specific embodiment
Below in conjunction with technical scheme and accompanying drawing, the in detail specific embodiment of the narration present invention.
Embodiment
Single bearing horizontal bearing capacity 800KN, adapts to 0 ° of the gradient～± 14 °.
Hinged-support base plate along bridge to wide 270mm, the long 381mm of direction across bridge, thick 20mm.
Two pieces of otic placodes are welded on base plate, otic placode is along bridge to long 230mm, high 150mm, thick 50mm.Otic placode top does 20 ×
20mm's smears angle process.Otic placode is symmetrically arranged on base plate, and otic placode is on base plate along bridge to staying 20mm, direction across bridge to stay 10mm, ear
Plate centre-to-centre spacing 231mm.
Board size of putting more energy into is 40mmx130mm, and thickness is 20mm, and one jiao of stiffener carries out smearing angle process.Stiffener vertical ear
Plate, and vertical base plate, with the two penetration welding is carried out.
Base plate, otic placode, ribbed stiffener material are Q345 steel.
Plus long pin shaft material is 30CrMnSi, diameter 49.5mm, finishing, holder method and traditional bearing pin phase are needed
Together, difference is that length is longer compared with traditional bearing pin.
