Description
Technical field
The utility model relates to a kind of bridge construction accessories, more particularly, to a kind of prestressing force small box girder internal mould device.
Background technique
In highway, railway, urban road are suggested, post-stressed prefabricated case beam is widely adopted, in the pre- of box beam
During system, box girder inner formwork floating is common phenomenon, cause box beam top plate and web concrete hardness is insufficient, box beam top plate and
Web reinforcement protective layer is insufficient, so that the quality accident for causing full wafer box beam to scrap.For the generation for preventing such quality accident, palpus
Properly settle the problem of box girder inner formwork floats in the prefabrication process of box beam.
Utility model content
The purpose of this utility model is that for above-mentioned problem provide it is a kind of using half opening internal model, prevent internal model from floating
The small box girder internal mould device of armored concrete.
A kind of prestressing force small box girder internal mould device of the utility model, including pedestal and the external mold being fixedly connected with pedestal and
The internal model being fixed in external mold, the internal model are connect by armored concrete with external mold；
Further, the outside of the external mold is also fixed with support frame, fixes external mold by support frame as described above and supports；
Further, the external mold includes left plate and right side plate, and the left plate passes through respectively with right side plate to be hinged on
On support frame.
Further scheme as the utility model: the internal model bottom is open state, when bottom slab concreting is completed and is shaken
After puddling reality, it is compacted using plank, effectively reduces the possibility of internal model floating.
Further scheme as the utility model: it is additionally provided with top adjustable screw at the top of support frame as described above, passes through
The top adjustable screw will be fixedly connected at left and right sides of support frame；
Further, internal model is held out against downwards by the top adjustable screw, resists the buoyancy of the internal model.
Further scheme as the utility model: the bottom of the external mold is also fixed with pressure thick stick, and the pressure thick stick passes through
Pull ring is connect with left template, right mould plate respectively.
The effect of the utility model is: 1, pouring case again using method and the lower concrete initial set of internal model bottom opening are preceding
The arrangement and method for construction of soffit of girder board concrete, reduces concrete to the buoyancy of internal model, and based on being vibrated with vibrating spear, supplemented by high frequency tamping
Concrete vibrating mode, reduce concrete in bobble rise velocity, be effectively reduced bubble rise drive internal model float impact force；
2, internal model is held out against downwards using increase crossbeam adjusting screw, resists internal model buoyancy.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, is described in detail the utility model.
As shown in Figure 1, a kind of prestressing force small box girder internal mould device disclosed by the utility model, including pedestal 1 and and pedestal
1 external mold being fixedly connected and the support frame 2 for passing through articulated connection with external mold, and support frame 2 is fixedly installed on pedestal 1；
Further, external mold includes left plate 4 and right side plate 5, and left plate 4 and right side plate 5 pass through top adjustable screw 3
Connection.
Further scheme as the utility model: to avoid concrete in casting process, because of 6 bottom surface contact surface of internal model
Greatly, biggish buoyancy is generated, internal model 6 is caused to float, fixed half opening 9 is equipped in internal model, so that bottom slab concreting is completed and is shaken
After puddling reality, compacting floating is carried out using plank, to reduce the possibility of the floating of internal model 6.
Further scheme as the utility model: being additionally provided with internal model 6 on the inside of external mold, internal model 6 passes through armored concrete (not
Mark) it is connect with external mold；
Further, when box beam carries out concreting, for the stabilization for guaranteeing internal model 6, pass through top adjustable screw 3
Internal model 6 is held out against downwards, to resist the buoyancy of internal model 6.
Further scheme as the utility model: box beam in concreting, for protect internal model 6 stabilization, in outer
Mould is equipped with pressure thick stick 8；
Pressure thick stick 8 is connect with left template 4, right mould plate 5 respectively by pull ring (not indicating), and by being set to 1 two sides of pedestal
Earth anchor 10 fasten, effectively prevent the floating of internal model 6.
The above content is only to illustrate the technical solution of the utility model, rather than to the limit of scope of protection of the utility model
System, the simple modification or equivalent replacement that those skilled in the art carry out the technical solution of the utility model, not
It is detached from the spirit and scope of technical solutions of the utility model.
