Description
Technical field
The utility model relates to a kind of jacking cylinder underneath type prefabricated subsection box girder inner formwork.
Background technology
At present, precast segmental beam case beam obtains using comparatively widely at home.Prior art prefabricated subsection box girder inner formwork many employings jacking cylinder is put, and top template declines separately, and side template is toward interior traversing structure.But this complex structure, studdle are many, formwork assembling and disassembling is difficult and operating space is very restricted, labor intensive material resources, and inefficiency.
Utility model content
The utility model overcome the deficiencies in the prior art and provide a kind of safe and convenient to use, the demoulding is simple, resistance to overturning good, formwork assembling and disassembling is few, operating space is large, effectively reduces labor strength, the jacking cylinder underneath type prefabricated subsection box girder inner formwork of enhancing productivity.
A kind of jacking cylinder underneath type prefabricated subsection box girder inner formwork, comprise jacking cylinder, support, top template and side template, described top template is fixed on the top of support, described side template symmetry is arranged on the both sides of top template and is supported by side direction oil cylinder, the bottom of described support with the axis of support for symmetry axis is symmetrically installed with multiple jacking cylinder, described jacking cylinder is supported on beam making bench or ground.
The bottom of described support with the axis of support for symmetry axis is symmetrically installed with multiple height-adjustable supporting leg, after jacking cylinder is supported to place, allow adjustable support leg bear load in construction, ensure that jacking cylinder does not stress in concreting process.
The bottom of described support is provided with roller set, is provided with track with on the ground of described roller set correspondence position, and described roller set is installed on the track.
Described side template is hinged on the both sides of described top template, and described side template can shrink and strut under the drive of described side direction oil cylinder.
Described support comprises bottom bracket and top-support, and described top template is fixed on top-support, described top-support with side template is provided with corresponding telescopic strut fixing point, described telescopic strut be used for the position of side template is fixed.
Owing to adopting said structure, jacking cylinder is arranged on frame bottom by the utility model, decreases inner chamber and installs the space that jacking cylinder and top template decline separately, make operating space become large.Be articulated and connected between top template and side template, the contraction of side template is controlled by oil cylinder, the demoulding is easy, and save the time of removing top template and side template, on bottom bracket, be also provided with adjustable support leg, the load produced when bearing the cast of beam section ensures that oil cylinder does not stress when beam section is poured into a mould simultaneously, protection jacking cylinder: top template is directly fixed on top-support, make template and support form entirety, effectively ensure that internal mold operating space; Telescopic strut is installed between top-support and side template, Control architecture sectional dimension, and dynamic changes process of constructing is on top-support; Support strut and be installed on top-support foremost, also will construct dynamic changes process to bed die for support, top support; Also roller is installed under bottom bracket, after completing for beam precast, under the traction of outside, by track, internal mold is shifted out Liang Taiwei processed.In sum, the advantages such as it is simple that the utility model has the demoulding, and formwork assembling and disassembling is few, and operating space is large, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figures 1 to 4, a kind of jacking cylinder underneath type prefabricated subsection box girder inner formwork, comprise jacking cylinder 1, support, top template 3, described support comprises top-support 4 and bottom bracket 2.Jacking cylinder 1 is fixed on bottom bracket 2, top template 3 is fixed on top-support 4, wherein top-support 4 is provided with the support strut 8 bearing service load, as shown in Figure 4, supporting strut 8 is be arranged between top-support 4 and bed die 12 to support, support strut 8 and be installed on top-support 4 foremost, also dynamic changes process be will construct to bed die 12 for support, top support 4, several the adjustable support leg 10 and the roller set 11 that are enough to bear duty load bottom bracket 2 will be provided with.Top template 3 and side template 6 are articulated and connected, and are controlled the contraction of side template 6 by side direction oil cylinder 5.Case beam inner chamber is provided with the dismountable telescopic strut 7 increasing internal mold rigidity, arranges at least two along the longitudinal direction and get rid of mould track 9 below roller set 11.
During the utility model formwork erection, first by HYDRAULIC CONTROL SYSTEM jacking cylinder 1, bottom bracket 2 jacking puts in place by the piston rod stretching out jacking cylinder 1, installs and supports strut 8, make top template 3 reach construction requirement.Regulate adjustable support leg 10 again, allow adjustable support leg 10 bear load in construction, ensure that jacking cylinder 1 does not stress.Then by HYDRAULIC CONTROL SYSTEM side direction oil cylinder 5, side template 6 is adjusted to the right place, telescopic strut 7 is installed, with fixed form position, strengthen formwork rigidity.Now internal mold is in the state upheld completely, keeps this state to carry out concreting, as shown in Figures 1 and 2.
When the utility model receives mould, first remove telescopic strut 7 and support strut 8, by HYDRAULIC CONTROL SYSTEM side direction oil cylinder 5, side template 6 being drawn in.Regulate adjustable support leg 10 again, by HYDRAULIC CONTROL SYSTEM jacking cylinder 1, jacking cylinder 1 piston rod is shunk, and internal mold entire lowering is to design height.As shown in Figure 3, after contraction template completes, internal mold can be shifted out from the precast beam section of having poured into a mould by outside elevator machine travel.
