Specific embodiment
- 3 are please referred to Fig.1, the utility model discloses a kind of cantilever cast-type box beam variable cross section internal model steel form, including
Left backform 11, left side mould 21, right side mould 22, width adjustment plates 30, adjusts screw 50 and outrigger 71 at right backform 12；The width
Adjustable plate 30 is connect respectively with the left backform 11 and right backform 12；11 lower end of left backform is provided with left hinge ear 41, described
Right 12 lower end of backform is provided with right hinge ear 42；The left hinge ear 41 is hinged with the left side mould 21 by adjusting screw 50, described
Right hinge ear 42 is hinged with the right side mould 22 by adjusting screw 50.
The left backform 11 and right backform 12 are integral by Bolted angle connection.The outrigger 71 passes through bolt and the left top
Mould 11 and right backform 12 connect.In the Construction of Transition Section of box beam inner cavity, outrigger 71 by U-bolt and the left backform 11 and
Right backform 12 connects.One end of the left backform 11 and one end of the left side mould 21 are hinged；One end of the right backform 12 with
One end of the right side mould 22 is hinged.The adjusting screw 50 includes cylinder 51, the first screw 52 and the second screw 53, the cylinder
51 both ends of body are threadedly coupled respectively with 52 and second screw 53 of the first screw.One end of first screw 52 is inserted into institute
It states in cylinder 51 and is threadedly coupled with the cylinder 51.One end of second screw 53 be inserted into the cylinder 51 and with institute
Cylinder 51 is stated to be threadedly coupled.Multiple threaded holes are provided in the width adjustment plates 30, as the adjustment left backform 11 and You Ding
During relative distance between mould 12, make threaded hole in the width adjustment plates 30 respectively with the left backform 11 and right backform 12
On threaded hole it is corresponding, then the threaded hole in width adjustment plates 30 and backform is passed through to can be realized and be relatively fixed with bolt.
Internal model steel form is supported when working by skid beam 72, and when demoulding unclamps fining twisted steel, and internal model steel form is with skid beam 72
It falls, you can demoulding, internal model steel form move forward with skid beam 72, you can realize the construction of subsequent cycle.Internal model steel form is shaped steel
With the Overall Steel Formwork of steel plate group weldering, left backform 11, right backform 12, left side mould 21 and 22 critical piece material of right side mould are by following
Material forms：Panel is 5mm steel plates, and interior muscle is 10# channel steels, and truss is 10# channel steels, and outrigger 71 is 20# I-steel, adjusts screw
50, U-bolt is 45# round steel.Internal model steel form is segmented in processing and fabricating to be processed, is assembled, is readily transported.
During construction, two side forms of the internal model steel form that furthered respectively with pull rod in beam body both sides, when pouring into a mould concrete to resist
The horizontal force of generation, side form behind be equipped with truss, truss have adjust screw 50, can easily adjusting template seam and take off
Mould.
Internal model steel form longitudinal length 4.5m, width 5.1m~5.6m adapt to the long 3m~4m of beam section.Inside molding plate can be whole
Body formwork erection and demoulding.
One of component of the internal model steel form of the utility model as hanging basket formwork is that cooperation cradle construction is used
, therefore the installation of internal model steel form is on condition that need hanging basket formwork first to install.After the skid beam installation suspension well of Hanging Basket, so as to
Combined inner mold steel form.Internal model steel form integral assembling before lifting is molded, and the size of formwork erection is adjusted to adjusting screw 50, so
Simultaneously spot welding is fixed in skid beam for integral hoisting successively afterwards.
When standard paragraphs are constructed and standard paragraphs expand section construction, when the reinforcing bar and prestressing force of box beam bottom plate, web and top plate
After the completion of Pipe installing, erection sequence successively：Outrigger, left backform 11, width adjustment plates 30, right backform 12, installation is left again
Side form 21, right side mould 22 and associated satellite part.Outrigger designs corresponding bolt hole with left backform 11,12 joint face of right backform,
One construction requirement is designed to that 2 grades are widened, i.e., the range that internal model steel form widens is 250mm and 500mm respectively, and with high-strength
Bolt 61 is locked.
Referring to Fig. 4, during Construction of Transition Section, after box beam inner cavity is broadened by standard section, changeover portion is one bell-mouthed
Cavity, internal model steel form is then accordingly irregular to be widened, and is equipped with the wide steel form of tune and is used, to adapt to the requirement of its width of constructing,
Due to standard paragraphs expand section be it is symmetrical parallel widen, with designed bolt hole adjust realize.During Construction of Transition Section, left top
With outrigger not in a plane, therefore can not be locked using bolt hole, transition can be realized using U-bolt 62 for mould, right backform
Section outrigger and left backform, the connection of right backform, since the design headroom of U-bolt is wider 50mm than outrigger, can realize certain
Angle adjusts.
The utility model has enough rigidity, bearing capacity and stability, disclosure satisfy that the requirement that user reuses,
The utility model has the following effects that compared with prior art：Due to using Overall Steel Formwork, mechanical precision high, only needed after formwork erection
Mechanical lead screw is held out against, can be begun to use without other adjustment, with traditional facet combined steel formwork and bamboo slab rubber
It compares, the utility model uses Overall Steel Formwork, lining cutting surface quality height and flat smooth, easy to use, formwork erection and demoulding
Faster, efficiency significantly improves.
The utility model is not limited to the above embodiment, if the various changes or deformation to the utility model do not take off
Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to comprising these changes and deformation.
