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 instrument destructiveness form removal, interior template is easy
Impaired modification, it is impossible to reuse.Problem above seriously increases difficulty of construction so that former hollow slab girder
In pull, mould 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.
In the work progress of double traitorous hollow slab girders, when beam slab length is long more than 16 meters, pour difficulty
More notable raising, due to the problem that the scale of construction is big, the horizontal and vertical lotus produced in concreting process
Load demand is too high, and in solid foam body, mould is the most out of shape when pouring, and yield rate is low, has a strong impact on construction quality.
Summary of the invention
The double traitorous hollow slab girder that the invention aims to solve length longer pours inner formwork support structure
Instability, yielding when pouring, after pouring, interior mould is difficult to remove, and causes construction cost high, inefficient
Problem, it is provided that one can dismantle use repeatedly, and laterally becomes with firm on-deformable pair of vertical supporting
Joint hollow plate beam internal model and two-way rigid locking supporting construction, can be repeatedly used for a long.
The technical solution adopted in the present invention is as follows: the interior template subsection setup before and after switching political loyalty, and utilizes little
