Description
Technical field
This utility model relates to a kind of novel construction beam, belongs to railway technical field of construction equipment.
Background technology
At present, when existing railway carries out culvert jacking, in order to ensure the normal operation of existing line above culvert, prevent
Railway station track subsides, and needs erection construction just beam that existing line carries out built on stilts reinforcing.
During erection construction just beam, need existing line is carried out the of short duration block of 1-2 hour, at present, construction beam
Set up and mainly lift up into row by the rescue of autocrane or railway interests.Due to working depth during crane lifting, during lifting
Also need to grid power blackout coordinate, had a strong impact on the operation of other equipment, meanwhile, hindered the operation of other parallel circuits, exist
Certain security risk.And use railway breakdown to hang, due to rescue hang be the rail vehicles in railway accident or its
Its barrier carries out the special purpose vehicle of lifting cleaning, is mainly used in urgent railway breakdown, it is desirable to stand ready, rescues
Helping to hang and once come into operation, it sets up needs flower long time so that complete the lifting of just beam in of short duration blocking time
Bringing difficulty, it addition, rescue is after suspension bracket sets, its dismounting is also required to the long period, once railway generation emergency, will be unable to and
Time arrive in, bring security risk.
The built on stilts reinforcing present stage of existing railway in operation has mainly used three kinds of technology, horizontal lifts vertical builder's jack sky method for strengthening: i.e.
Using rail beam to do longeron, 40H shaped steel does crossbeam and lifts the built on stilts hardened link method on take-up road, the parts that this method needs
More, structure is complicated and unstable, and safety coefficient is little, it is desirable to train speed limit 25km/h, it is impossible to meet movement requirement, does not builds
View uses；D type construction beam makes somebody a mere figurehead method for strengthening: i.e. use the D type construction beam of sizing to make somebody a mere figurehead hardened link, existing have D12,
Tetra-kinds of spans of D16, D20, D24, the method simple in construction, safety and stability, but, maximum span is only 24 meters, can not meet big
Span structure passes through needs, and bigger to span or that oblique angles the is bigger frame bridge construction suitability is poor, even phase
There is also weight with the construction beam of span the heaviest, girder is higher is unfavorable for the problems such as construction；Construction beam is built on stilts continuously adds
Gu method, the method that the large-scale steel I-beam of fixing modulus uses equal strength connect forms the continuous beam of long span, and centre sets
One or more fulcrums define redundant structure, but, with curve half in the case of double track railway section distance between centers of tracks is less
Also cannot use when footpath is less, large-scale steel I-beam lateral stiffness is not enough, and less stable is unfavorable to traffic safety, and cost is high,
Particularly cannot use Large-scale Hoisting equipment in electrified sections, use and there is beam body when manually setting a roof beam in place and topple the peaces such as unstability
Full blast danger.
Utility model content
The purpose of this utility model is to provide a kind of novel construction beam to solve the problems referred to above；Due to this just beam
The a length of 32.6m of girder arranged, deck-molding 1.7m, deck-siding 0.48m, girder uses Q345qD steel with crossbeam material, not only subtracts
The weight of few construction beam, greatly reduces the difficulty of construction middle girder lifting, and width of main beam is less, for two-wire, multi-thread line
The frame bridge construction on road and the frame bridge construction of the less circuit of sweep also have the preferable suitability, are also applied for single case span
The undercrossing tunnel frame bridge construction that bigger or oblique angles is bigger, and the construction of the undercrossing tunnel frame bridge of many casees；Meanwhile,
This crossbeam that just beam is arranged may be provided in highest order, a secondary high position, middle position, secondary low level, five kinds of positions of lowest order, thus can be suitable for
Construction basis in multiple different depth；It addition, the increasing of this just girder construction span, promote to cancel during Framed underpass bridge
The construction procedure of temporary support and system transform, thus decrease the construction period of Framed underpass bridge, largely save
Construction cost, is suitable to railway and makes somebody a mere figurehead the construction of hardened link and promote the use of.
In order to achieve the above object, this utility model is realized by following technological means.
A kind of novel construction beam, it is by girder, splice plate, crossbeam, bracket, connecting plate, dividing plate, slag trap, strength plate, gear
Foot, hand hole part combine, and it is characterized in that: the upper and lower two ends of girder are provided with the first cover plate, and the first cover plate upper end is provided with and adds
Strong plate, is provided with multiple dividing plate in girder, dividing plate both sides arrange energetically plate, and girder lower end is provided with rubber support, support plate, rubber
Glue bearing is fixed with support plate by gear foot；Girder is fixedly connected by bracket, connecting plate and 49 crossbeams, and crossbeam is upper and lower
Both sides are provided with the second cover plate, and the second cover plate lower end is provided with slag trap, is provided with the first web, on the first web in the middle part of crossbeam
It is provided with fixed plate, gripper shoe, is fixedly connected by first segment plate, brace, second section plate, Section of three plate between crossbeam.
The a length of 32.6m of described girder, deck-molding 1.7m, deck-siding 0.48m, girder is spliced by 3 sections, sections it
Between be fixedly connected by splice plate, splice plate both sides and the second web are provided with hand hole, splicing form is bolt splicing.
Described crossbeam riding position is divided into highest order, a secondary high position, middle position, secondary low level, lowest order, 49 crossbeam adjacent row
Row, the spacing between crossbeam is 670mm.
Described girder uses Q345qD steel with crossbeam material.
The three of girder sections are first used splice plate splicing by operation principle: before undercrossing tunnel frame bridge holds out against construction
After complete, a girder is fallen within side supports plate, then crossbeam is connected with girder through use bracket, connecting plate from rail
Connecing, crossbeam top is connected with rail by rail fastening, then, is connected with another root girder by crossbeam by bracket, connecting plate,
Then, first segment plate, second section plate, Section of three plate, brace are connected with crossbeam, Framed underpass bridge after installing, can be started
The excavation of construction.
This utility model mainly has the advantages that
1, this length of 32.6m of girder that just beam is arranged, deck-molding 1.7m, deck-siding 0.48m, girder uses with crossbeam material
Q345qD steel, not only reduce the weight of construction beam, greatly reduce the difficulty of construction middle girder lifting, and width of main beam is relatively
Little, the frame bridge for two-wire, multi-thread circuit is constructed and the frame bridge construction of the less circuit of sweep also has the most applicable
Property, it is also applied for the single undercrossing tunnel frame bridge that case span is bigger or oblique angles is bigger construction, and wears ferrum under many casees
The construction of road frame bridge.
2, this crossbeam that just beam is arranged may be provided in highest order, a secondary high position, middle position, secondary low level, five kinds of positions of lowest order, so
Just go for the construction basis of multiple different depth.
3, the increasing of this just girder construction span, promotes to eliminate temporary support and system transform during Framed underpass bridge
Construction procedure, thus decrease the construction period of Framed underpass bridge, largely saved construction cost, be suitable to railway frame
The construction of empty hardened link is promoted the use of.
