Abstract
The invention discloses a kind of sliding system applied to section box girder small chamber internal model, including inner membrance, the inner membrance includes inner membrance template and inner membrance back cord, two groups of sliding systems before and after configuration below the internal model, be equipped with track below the sliding system, the track top and be equipped with jacking cylinder between two groups of sliding systems.The invention has the advantages that of simple structure and strong practicability.
Description
Technical field
The present invention relates to section box girder inner formwork system field, particularly a kind of cunning applied to section box girder small chamber internal model
Shifting system.
Background technology
In the design of section box girder internal model, it is quick de- to realize that the sliding internal model that can be slided in track is used sometimes
Mould, shifting formwork, would generally use the form that tank wheel is added under interior mould bases at this time.But such a form occupied space is more, when
It when running into small chamber internal model, because of chamber interior volume deficiency, can not use, small punching block mechanical support or simple can only be used at this time
Wooden model, the former high labor cost, safety coefficient are low, and the latter's recycling rate of waterused is low, are not suitable for batch precast segment.
The content of the invention
The purpose of the present invention is to solve the above problem, devises a kind of cunning applied to section box girder small chamber internal model
Shifting system.
Realize above-mentioned purpose the technical scheme is that, a kind of slip system applied to section box girder small chamber internal model
System, including inner membrance, the inner membrance include inner membrance template and inner membrance back cord, two groups of sliding systems before and after being configured below the internal model,
The sliding system is by the connecting plate of welding, the steel positioned at connecting plate lower section and the integral profile of welding resistance below internal model back cord
Plate, the position-limited wheel of both sides, the wheel group positioned at side below steel plate collectively form above steel plate, under the sliding system
Side is equipped with track, the track top and is equipped with jacking cylinder between two groups of sliding systems.
The sliding system is directly bolted by connecting plate with the internal model back cord being welded on inside molding plate and use.
The left and right offset of the position-limited wheel limitation sliding system, while prevent toppling under internal model formwork state.
The track is welded by two H profile steels.
The sliding system applied to section box girder small chamber internal model made using technical scheme, the slip system
System is formed using steel plate and pulley blocks weldering, and simple in structure, easy processing, is directly connected to by sliding system and internal model, then is arranged in
Mode on track, has cancelled the internal mould supporter and tank wheel of conventional internal model sliding system, has effectively saved inner cavity chamber space, make
Small chamber internal model can realize fast demoulding, and remove prefabricated beam section inner cavity by track, improve work efficiency, left by setting
Right limit wheel, ensure that the stability of inner formwork system, eliminate the security risk of offset rail, easy-to-use, easy structure
Improve design process velocity.

Embodiment
The present invention is specifically described below in conjunction with the accompanying drawings, as shown in figures 1 to 6, one kind is applied to section box girder small chamber
The sliding system of internal model, including inner membrance 1, the inner membrance 1 include inner membrance template 2 and inner membrance back cord 3, the lower section of internal model 1 configuration
Front and rear two groups of sliding systems 4, the sliding system 4 by the connecting plate 5 positioned at the welding of the lower section of internal model back cord 3, under connecting plate 5
The steel plate 6 of side and the integral profile of welding resistance, the position-limited wheel 7 of both sides, the wheel group 8 positioned at 6 lower section side of steel plate above steel plate 6
Collectively form, be equipped with track 9 below the sliding system, set above the track 8 and between two groups of sliding systems
There is jacking cylinder 10；The sliding system is by connecting plate 4 directly with the internal model back cord 3 that is welded on inside molding plate 2 and using
It is bolted；The position-limited wheel 7 limits the left and right offset of sliding system, while prevents toppling under internal model formwork state；It is described
Track 9 is welded by two H profile steels.
The characteristics of the present embodiment, is, positioned at the steel plate of connecting plate lower section and the integral profile of welding resistance, above steel plate
The position-limited wheel of both sides, the wheel group positioned at side below steel plate collectively form, which is formed using steel plate and pulley blocks weldering,
Simple in structure, easy processing, is directly connected to by sliding system and internal model, then the mode being arranged on track, has been cancelled in routine
The internal mould supporter of mould sliding system and tank wheel, effectively save inner cavity chamber space, small chamber internal model is realized fast demoulding,
And prefabricated beam section inner cavity is removed by track, improve work efficiency, by setting left and right position-limited wheel, ensure that inner formwork system
Stability, eliminates the security risk of offset rail, easy-to-use, and easy structure improves design process velocity.
In the present embodiment, then connecting plate and the integral profile of steel plate welding resistance are assembled position-limited wheel and wheel group by worker,
Sliding system is directly bolted by connecting plate with the internal model back cord use being welded on inside molding plate, and two H profile steels are welded
Connect and form track, two groups of sliding systems before and after the configuration of each internal model, during formwork, are dragged internal model and sliding system by jacking cylinder
Rise, wheel group is de-orbited（H profile steel lower flange）, meanwhile, position-limited wheel plays the role of spacing and overturn-preventing, when receiving mould, shrinks
Jacking cylinder makes internal model and sliding system drop in track（H profile steel lower flange）On, internal model web is packed up, using hoist engine by internal model
It is overall to haul out beam body inner cavity chamber.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of which part may be made, belong to protection scope of the present invention it
It is interior.
