Description
Technical field
The invention belongs to road engineering die plate equipment technical field, more particularly to a kind of pour the interior of hollow concrete plate-girder
Mould supporting construction.
Background technology
Concrete plate beam used in Expressway Road construction is hollow slab girder, will when pouring hollow slab girder formwork
Internal model board supporting structure is used, can be from hollow slab girder side ports by inner formwork support structure after hollow slab girder pours coagulation forming
Release to remove and pull out.
With the raising in expressway construction to road capacity requirement, to concrete hollow slab girder used in engineering
The improvement being made that on construction, hollow slab girder have made the bearing capacity for the hollow slab girder for becoming nodal section, increasing cored slab.
Due to the change of hollow slab girder construction, hollow slab girder changes in the traitorous place closing in position size in inner chamber, after plate-girder pours,
Internal model is stuck in the inner chamber of hollow slab girder, and pull does not come out, it has to carries out destructive dismounting to internal model, causes back
Concrete is destroyed, and has a strong impact on quality and the template life-span of hollow slab girder.And using instrument destructiveness form removal
During, the easily damaged modification of inner template, it can not reuse.Problem above seriously increases difficulty of construction so that former cored slab
Beam pull internal model exits use.
In current work progress, in order to complete to become the pouring construction of nodal section hollow slab girder, it has to using solid foam
Internal mould, pour rear foams internal model and be left in change nodal section hollow slab girder, belong to disposable product, due to engineering consumption
Greatly, the problem of use of disposable foams internal model causes construction cost too high, and the soft deflection of foams internal model matter is big, nothing
Method ensures hollow slab girder quality.
The content of the invention
Inconvenient the invention aims to solve the dismounting of hollow plate beam internal model supporting construction, supporting construction is unstable,
Cause the problem of construction cost is high, efficiency is low, there is provided one kind can dismantle uses repeatedly, and laterally with vertical supporting is firm is not easy
Double traitorous hollow plate beam internal models of deformation and two-way rigid locking supporting construction, can be repeatedly used for a long.
To achieve these goals, the technical solution adopted in the present invention is by Integral type movable supporting construction, is passed through
The mode of jointed shaft rotary moveable pull releases vertical and horizontal support, overall to be pulled out from hollow slab girder side ports.
Drawing and pulling type hollow plate beam internal model supporting mechanism of the present invention, by fixed support beam frame, upper support and lower support, collateral support
Formed with rotary gemel；The described elongated setting of fixation support beam frame rectangular frame structure, along the upside of fixed support beam frame
Uniform intervals are supported on setting, and lower support is set along the bottom side uniform intervals of fixed support beam frame, along a left side for fixed support beam frame
Right both sides difference uniform intervals set collateral support；Described upper support and lower support and collateral support are hinged by rotary gemel respectively
On fixed support beam frame.
Described upper support and lower support and collateral support are in plank frame, and plate face is laterally set along fixed support beam frame.
Described upper support and lower support and side bearing height are set according to cored slab internal model depth.
Described upper support and lower support and collateral support are in respectively 0-90 ° of flexible movable angle between fixed support beam frame.
Described rotary gemel is provided with movable rotation-shaft and fixed rotating shaft, and movable rotation-shaft is movably hinged with fixed support beam frame
Connection is fixedly mounted with upper support or lower support or collateral support in installation, fixed rotating shaft.
Described fixed rotating shaft is in 135 ° of angles with upper support or lower support or collateral support.
The beneficial effects of the present invention are：Supporting construction is simplified, changes lock mode, makes supporting construction dismounting side
Just, operating efficiency is improved；Laterally strengthen with vertical supporting, improve Forming Quality and qualification rate；Integrated rotating locks machine
It is convenient that structure is removed, and pull is laborsaving, improves job security, reduces the loss to internal model, increases template service life, drop
Low construction cost.
