Description
Technical field
The invention belongs to road engineering die plate equipment technical field, particularly relate to one and pour traitorous hollow mixed
The interior mould of concrete board beam and support system.
Background technology
Concrete plate beam used in Expressway Road construction is hollow slab girder, along with highway is built
If the raising in required road capacity, is made that structure to concrete hollow slab girder used in engineering
On improvement, hollow slab girder has been made the hollow slab girder with traitorous face, has been increased the carrying energy of cored slab
Power.Due to, the change of hollow slab girder structure, hollow slab girder internal cavities structure creates change, in the past
In the pull pouring hollow slab girder, mould cannot use, and reason is that inner chamber is switched political loyalty and locates closing in position size
Changing, after plate-girder pours, interior mould is stuck in the inner chamber of hollow slab girder, pull the most out,
Internal mould of having to carries out destructive dismounting, causes back concrete to be destroyed, has a strong impact on hollow
The quality of plate-girder and template life-span.And during using the rigid form removal of instrument, interior template is easily subject to
Damage modification, it is impossible to reuse.Problem above seriously increases difficulty of construction so that former hollow slab girder is taken out
La Neimo exits use.
In current work progress, in order to complete the pouring construction of traitorous face hollow slab girder, it has to use
Mould in solid foam body, in pouring rear foams, mould has been left in the hollow slab girder of traitorous face, belongs to once
Sex aids, owing to engineering consumption is big, in disposable foams, the use of mould causes construction cost too high
In problem, and foams, the soft deflection of mould matter is big, it is impossible to ensure hollow slab girder quality.
Summary of the invention
The invention aims to solve double traitorous hollow slab girder pour interior mould and be difficult to remove, construction cost
High problem, it is provided that a kind of traitorous hollow plate beam internal model that can repeatedly dismantle use and support system, structure
Making fine, construction quality is firm, easy to loading and unloading, can be repeatedly used for a long.
The technical solution adopted in the present invention is that inside molding plate opsition dependent structure is divided into multiple module, at mould
At Kou, unification is switched political loyalty, and piecemeal template volume is little, easily disassembled taking-up, overcomes original template to be stuck in hollow slab girder
The problem not can not taken out in inner chamber；By support structure designs be can the folding and unfolding of overall machinery, body is reduced
Structure, easily sets up and dismounting, overcomes old supporting construction dismounting complexity, the most impaired, is not easily taken out of and asks
Topic.
The double traitorous hollow plate beam internal model of the present invention and support system include Nei Mo and supporting construction two parts,
Support structure is fixedly supported on the hollow cavity of the double traitorous hollow slab girder of interior mould Inner Constitution；Interior mould is flat by top
Face mould, upper left angle mould, upper right angle mould, baseplane mould, lower-left angle mould and lower right corner die combination are spliced to form
Switch political loyalty in mould structure, rectangular cavity housing, corner angle are chamfer；Supporting construction by upper horizon bar,
Lower horizon bar, transverse support bar and vertical supporting bar composition；Upper horizon bar and lower horizon bar upper and lower water respectively
Plain cloth is put, and position is vertically opposite；By vertical supporting bar chain connection between upper horizon bar and lower horizon bar；
By transverse support bar chain connection between the upper horizon bar of adjacent two or adjacent two lower horizon bars.
Described interior mould, top plane mould, upper left angle mould, upper right angle mould, baseplane mould, lower-left angle mould and
Bottom right angle mould uses at traitorous place chamfered transition to switch political loyalty and constructs.
Vertical supporting bar in described supporting construction divides front support rod and back support rod, and front support rod is installed
Between upper horizon bar and lower horizon bar behind traitorous face, back support rod is arranged on the upper level in face of switching political loyalty
Between bar and lower horizon bar.
Described lower horizon bar is made up of front horizon bar, rear horizon bar and traitorous bar, front horizon bar and Hou Shui
Flat bar is horizontally disposed with, and the middle traitorous bar by being obliquely installed is hinged.
The change of upper horizon bar in described supporting construction and the link changing locations of lower horizon bar and length and interior mould
Joint position and length are identical.
The outside entirety of described interior mould is tied up and wraps up plastic sheeting.
The beneficial effects of the present invention is and improve molding qualification rate height and efficiency of construction, reduce and be constructed into
This, be in particular in: disclosure satisfy that traitorous hollow concrete plate-girder casting process produces laterally and perpendicular
To the needs of load, in work progress, deflection is low, stabilized structure, and conforming product rate is high；Supporting construction
Overall employing mechanical type structure, it is possible to being folded by linkage integral-rotation, after folding, body diminishes,
Directly can take out out after force folding at die orifice, take out difficulty and reduce, construct simple and reliable, safety
Height, substantially increases efficiency of construction；Template piecemeal forms, easily de-from the concrete beam body poured
Fall, can easily at die orifice pull take out, template damage degree is low, intact, can be repeated several times and make
With, greatly reduce construction cost.
