Description
Technical field
This utility model relates to a kind of construction beam, belongs to railway technical field of construction equipment.
Background technology
When existing railway carries out culvert jacking, in order to ensure normal operation and the maintenance of existing line above culvert, prevent
Only 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 both
There is the of short duration block that circuit carries out 1-2 hour.
At present, the built on stilts reinforcing present stage of existing railway in operation has mainly used three kinds of technology, horizontal lift vertical builder's jack sky and reinforces
Method: 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, and this method needs
Parts are more, and 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, existing
It is not recommended that use；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
There are tetra-kinds of spans of D12, D16, D20, D24, although this method safety and stability, but, existing D24 splice type construction beam
Splicing form is only available for the use of single span, occupation mode underaction；Construction beam makes somebody a mere figurehead method for strengthening continuously, will be fixing
The method that the large-scale steel I-beam of modulus uses equal strength to connect forms the continuous beam of long span, and centre sets one or more
Point define redundant structure, but, in the case of double track railway section distance between centers of tracks is less and sweep less time also without
Method uses, and large-scale steel I-beam lateral stiffness is not enough, and less stable is unfavorable to traffic safety, and cost is high, particularly electrically
Change railway section and cannot use Large-scale Hoisting equipment, use and there is beam body when manually setting a roof beam in place and topple the significant security risk such as unstability.
Utility model content
The purpose of this utility model is to provide a kind of construction beam to solve the problems referred to above；Due to this just beam be by
Three sections are spliced, and be possible not only to all splice use as D24 type construction beam in work progress, it is also possible to can be by
One sections and the splicing of the second sections use as D20 type construction beam, it is possible to splice the second sections and the 3rd sections as D16
Type construction beam uses, it is possible to be used alone as D12 type construction beam by the second sections, it is achieved that a kind of construction beam is multiple
Span uses；It addition, this just girder construction simple, reasonable in design, occupation mode is very flexible, is suitable to railway and makes somebody a mere figurehead hardened link
Construction is promoted the use of.
In order to achieve the above object, this utility model is realized by following technological means.
A kind of construction beam, it is by girder, splice plate, brace, primary nodal point plate, crossbeam, the first bracket, connecting plate, rubber

Slag trap, is fixedly connected by the 3rd gusset plate, secondary nodal point plate, brace, primary nodal point plate between some crossbeams.
Described girder is to be spliced by three sections, and a length of 7895mm of first segment, second section segment length is
12730mm, the 3rd a length of 3827mm of sections, first segment and the second sections, the second sections and the 3rd sections are by splice plate phase
Fixing connection, splice plate and girder web plate are provided with hand hole.
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 by crossbeam from rail through use the first bracket, the second bracket,
Connecting plate is connected with girder, and crossbeam top is connected with rail, then, by the first bracket, the second bracket, company by rail fastening
Crossbeam is connected by fishplate bar with another root girder, then, by primary nodal point plate, secondary nodal point plate, the 3rd gusset plate, brace and crossbeam
Connect, the excavation of Framed underpass bridge construction after installing, can be started.
This utility model mainly has the advantages that
1, this just beam be to be spliced by three sections, be possible not only to all to splice in work progress and construct as D24 type
Just beam uses, it is also possible to can first segment be used as D20 type construction beam with the second sections splicing, it is possible to by the second sections
Use as D16 type construction beam with the 3rd sections splicing, it is possible to the second sections is used alone as D12 type construction beam,
Achieve a kind of multiple span of construction beam to use.
2, this just girder construction simple, reasonable in design, occupation mode is very flexible, is suitable to railway and makes somebody a mere figurehead the construction of hardened link
Promote the use of.
