Description
Technical field
The invention belongs to road engineering die plate equipment technical fields more particularly to one kind pouring traitorous hollow concrete plate-girder
Internal model and support system.
Background technology
Concrete plate beam used in Expressway Road construction is hollow slab girder, with the roads expressway construction Zhong Dui
The raising that road bearing capacity requires is made that improvement structurally, hollow slab girder are done in engineering to concrete hollow slab girder used
At the hollow slab girder for carrying variable cross-section, the bearing capacity of cored slab is increased.Since the variation of hollow slab girder construction is hollow
Plate-girder internal cavities construction produces variation, and being previously used for pouring the pull internal model of hollow slab girder can not use, and reason is interior
The traitorous place closing in position size of chamber changes, and after plate-girder pours, internal model is stuck in the inner cavity of hollow slab girder, and pull is not
Out, it has to destructive dismounting be carried out to internal model, cause back concrete to be destroyed, seriously affect the matter of hollow slab girder
Amount and template service life.And during using tool destructiveness form removal, the easily damaged modification of inner template can not repeat to make
With.Problem above seriously increases difficulty of construction so that former hollow slab girder pull internal model exits use.
In current work progress, in order to complete the pouring construction of variable cross-section hollow slab girder, it has to use solid foam
Internal mould pours rear foams internal model and has been left in variable cross-section hollow slab girder, belongs to disposable product, since engineering consumes
Amount is big, the problem that the use of disposable foams internal model causes construction cost excessively high, and the soft deflection of foams internal model matter is big,
It can not ensure hollow slab girder quality.
In the work progress of double variable cross-section hollow slab girders, when beam slab length is long more than 16 meters, it is even more aobvious to pour difficulty
It writes and improves, due to the big problem of the scale of construction, the transverse direction and vertical load demand generated in concreting process is excessively high, solid foam
Internal mould is easily out of shape when pouring, and yield rate is low, seriously affects construction quality.
Invention content
The purpose of the present invention is to solve the longer double variable cross-section hollow slab girders of length to pour inner formwork support structure shakiness
It is fixed, it is yielding when pouring, it pours rear internal model and is not easy to remove, cause the problem that construction cost is high, efficiency is low, providing one kind can be anti-
Multiple dismounting uses, and transverse direction and the firm on-deformable double variable cross-section hollow plate beam internal models of vertical supporting and two-way rigid locking branch
Support structure can be repeatedly used for a long.
The technical solution adopted in the present invention is as follows：It is easy using small template by the inner template subsection setup before and after variable cross-section
The characteristics of taking-up, dismantles in advance, reduces dismounting difficulty；Using the supporting way of hinge type moving fastening, fixed and locking is horizontal
The transverse direction of supporting rod makes support construction transverse direction vertical supporting consolidate with vertically, and stress is strong, simultaneously supports structure and is simplified, living
Dynamic fastener is removed more convenient；Enhance support construction transverse strength using triangular support configurations.
Double variable cross-section hollow plate beam internal models of the invention and two-way rigid locking support construction include internal model and support construction, branch
Support structure is supported in the cavity of internal model, and internal model is by mould, osculum section right side mould, big mouth section left side on the left of end template, osculum section
The traitorous internal model of mould and the combined and spliced composition of top template construction, rectangular cavity shell, corner angle fall for inclined-plane on the right side of mould, big mouth section
Angle, end template prop up the left side template of mould and big mouth section left side mould splicing composition internal model on the left of internal model bottom, osculum section, osculum
The right side template of mould composition internal model, top template are covered in the top of internal model on the right side of section right side mould and big mouth section；Support construction be by
Vertical supporting pull rod, cross-brace pull rod and the lateral diagonal brace pull rod fixation that four horizontal support bars are arranged by uniform intervals are taken
The rectangular frame of composition is connect, horizontal support bar is fixed by vertical supporting pull rod vertical supporting, and horizontal support bar passes through cross
It is fixed to tie-strut and lateral diagonal brace pull rod cross-brace；Horizontal support bar includes two upper level course upper water disposed in parallel
Flat supporting rod and two lower level course lower horizontal support bars disposed in parallel；Under the lower end and left or right side of vertical supporting pull rod
Horizontal support bar is hinged, upper end and horizontal support bar snapping on homonymy；One end of cross-brace pull rod and upper horizontal support bar or
One of lower horizontal support bar is hinged, another snapping of the other end and same level layer；One end of lateral diagonal brace pull rod is hinged on
Close to the position of snapping end, the other end is movably articulated in the same root hinged with cross-brace pull rod cross-brace pull rod
On horizontal support bar or lower horizontal support bar, bolt cam support construction is formed with cross-brace pull rod.
Mould and osculum section right side mould are the shell template that two sides are equipped with inclined-plane corner on the left of the osculum section.
Mould and big mouth section right side mould are two halves along intermediate hinged shell template symmetrical above and below on the left of the big mouth section.
The vertical supporting pull rod is vertically fixed between the upper horizontal support bar of the same side and lower horizontal support bar.
The vertical supporting pull rod uniform intervals are arranged between horizontal support bar and lower horizontal support bar, and difference is cut
Be arranged at face vertical supporting pulling rod structure is identical, size is with cross-sectional length.
Two upper horizontal support bars that the cross-brace pull rod is vertically fixed on same level layer are horizontally-supported under
Between bar.
One end of the vertical supporting pull rod is equipped with hinged circular hole, and the other end is equipped with buckle.
One end of the cross-brace pull rod is equipped with hinged circular hole, and the other end is equipped with buckle, is opened again close to buckle inside
Equipped with a hinged circular hole.
The lateral diagonal brace pull rod offers hinged circular hole close to two ends position.
The beneficial effects of the present invention are：Support construction is simplified, lock mode is changed, makes support construction dismounting side
Just, it improves work efficiency；Laterally reinforce with vertical supporting, improves 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.
