Description
Technical field
This utility model is related to prefabricated case beam manufacturing technology field, in particular to a kind of precast box beam hydraulic internal model.
Background technology
Box beam is one kind of science of bridge building central sill, and internal is hollow shape, and there is the edge of a wing top both sides, is similar to chest, thus obtains
Name.Box beam is divided into prefabricated case beam and cast-in-situ box girder, and wherein prefabricated case beam, can be with reference to Bridge Erector after the completion of independent place is prefabricated
Set up after the completion of the engineering of bottom, project progress can be accelerated, the duration is saved, be bridge formation means conventional at present.It is real in production
In trampling, it is often necessary to set up precast box beam hydraulic internal model in box beam before pouring, to guarantee that what is poured is smoothed out.
Wherein, precast box beam hydraulic internal model of the prior art mainly includes multiple bases, the setting along suitable bridge to arrangement
Multiple jacking cylinders, the piston being connected with multiple jacking cylinders respectively and the gang form being connected with piston on base,
Field Force is by base along along bridge, to fixing, be fixedly connected sequentially on each base jacking cylinder, and jacking cylinder is along suitable
Bridge is risen or is fallen by jacking cylinder band piston in the vertical direction, so that gang form is reached in single-row arrangement
Specified location, to guarantee that what is poured is smoothed out.
However, present inventor has found, precast box beam hydraulic internal model of the prior art, as jacking cylinder is single
Arrange, stability in the large is bad, along bridge to intensity it is not enough, lead to not integral hoisting and transport；And due to jacking cylinder
For single setting, therefore in order to ensure jacking cylinder does not shift in motor process, need to arrange in jacking cylinder and live
Plug, thus it is higher to the quality of fit requirement of jacking cylinder and piston, if piston is not high with the quality of fit of jacking cylinder, repeatedly
After use, piston can occur abrasion deformation, so as to cause precast box beam hydraulic internal model integrally to deform upon, and then cause overall mistake
Surely, therefore using the precast box beam hydraulic internal model of prior art, stability is not high, it is impossible to life-time service.

And extend the service life of the precast box beam hydraulic internal model that this utility model embodiment is provided.
During practical application, in order that base 10 is more easily coordinated with deck type longeron 20, as Figure 3-Figure 4, base
It is provided with the supporting parts 11 for support deck type longeron 20 on 10, the bottom of deck type longeron 20 is provided with and supporting parts 11
The projection 22 matched somebody with somebody, using this kind of setting, when jacking cylinder 21 is packed up completely, raised 22 are coordinated with supporting parts 11, so as to ensure
Deck type longeron 20 is interfixed with the position of base 10.
During practical application, in order that deck type longeron 20 is not susceptible to offset during rising or falling, such as Fig. 1-
Shown in Fig. 2, deck type longeron 20 includes：Along along bridge is to the framework 23 that the cross section for arranging is rectangle and is arranged on 23 liang of framework
Side, the support member 24 for corresponding to each setting of base 10 respectively, jacking cylinder 21 are connected with the bottom of support member 24, are set using this kind of
Put, the spacing of two row jacking cylinders 21 can be made bigger, so that the support force suffered by deck type longeron 20 is more dispersed, it is to avoid by
Excessively concentrate in 20 stress of deck type longeron, so as to cause deck type longeron 20 to shift during rising or falling.
Wherein, for the ease of dismantling jacking cylinder 21, as Figure 3-Figure 4, the fixing end of jacking cylinder 21 is provided with method
Blue disk 25, the bottom of support member 24 are provided with the screwed hole matched with ring flange 25, are arranged on using energy after finishing using this kind of
It is enough that jacking cylinder 21 is separated with the dismounting of deck type longeron 20, be readily transported, if while jacking cylinder 21 damage also can be independent
Jacking cylinder 21 is changed, so as to extend the service life of the precast box beam hydraulic internal model of this utility model embodiment offer.
During practical application, for the ease of lifting, on deck type longeron 20, suspension ring are provided with.
Wherein, as shown in figure 5, the precast box beam hydraulic internal model that this utility model embodiment is provided includes：Along along bridge to according to
The end segment section 50 of secondary setting, variable cross-section section 51 and standard sections 52, deck type longeron 20 are arranged at end segment section 50, variable cross-section section
51 and standard sections 52 in, so as to ensure it is overall to concrete component 1 play a supporting role, base 10 is uniformly arranged on standard
In sections 52, and link 12 is provided between each base 10, using this kind of setting, ensure that phase between each base 10
To fixation, so as to improve the stability of base 10, meanwhile, base 10 is arranged in standard sections 52, each base 10
Structure is identical, while the shape of link 12 is also identical, can reduce difficulty of construction.
Specifically, for the deck type longeron 20 of support end sections 50, as shown in figure 5, deck type longeron in end segment section 50
20 bottom is provided with temporary support 60, and temporary support 60 typically selects jack, so as to opposite end sections 50 on hold
Formula longeron 20 plays temporary support effect, cost-effective, while can also reduce difficulty of construction.
