Description
Technical field
The present invention relates to a kind of box girder inner formwork constructing structure, relate in particular to a kind of medium and small span low altitude prefabricated case beam internal mold and job practices thereof.
Background technology
In bridge on highway was built, the application of prestressing force prefabricated case beam was more and more general.And its prefabricated box girder inner formwork adopts gang form more.It is maximum a kind of template form of using in the engineering construction.It is made up of plate, angle mould, support and the connector of the some types with certain modulus, can risk multiple size and geometry with it.Can directly assemble at the scene during construction, can also be assembled into the bulk template in advance or component template is installed with crane for hoisting.The plate of gang form has all steel material to make, also useful steel framework and compound the making of wood (bamboo) plywood panel.Gang form not only is used for construction work, bridge engineering, and underground construction is extensive use also.But manually enter relatively difficulty of the indoor stripping of case for the low clearance combined inner mold, consuming time taking a lot of work not only makes construction cost increase, and influences construction speed; In addition, when removing, model is knocked, box girder inner formwork is deformed, the beam physique amount of construction after the influence.Learn 4 of the patents of having authorized by retrieval in addition: 1, " hinge four-lever mechanism hydraulic box beam internal mould " application (patent) number CN200710035532.9 way is: this hinge four-lever mechanism hydraulic box beam internal mould, comprise the side direction oil cylinder that moving platen outwards opens or inwardly draws in girder, top template, last moving platen, following moving platen, the drive, also comprise two rocking bars, connect by two rocking bar radial types between described top template and the last moving platen.The present invention by two rocking bars respectively with top template and last moving platen on otic placode hinged, they have formed four-bar linkage, drive by driving the oil cylinder of going up the inside receipts of moving platen, going up moving platen when this oil cylinder is flexible is that radius is done circular motion with two rocking bars, last dynamic model and concrete no longer interfere in the time of can guaranteeing the demoulding like this, can adopt hydraulic way to realize the overall shrinkage of template, case beam quality is guaranteed, and can make the easy to loading and unloading of template, fast, time saving and energy saving, greatly the reduction of erection time, enhance productivity, reduce labour intensity, thereby can guarantee speed of production, adapt to the production in enormous quantities of case beam.2, " full-automatic hydraulic prefabricated box girder inner formwork system " application (patent) number CN200610201284.6 way is: inner formword is gone up the inner corner trim mould and a pair of following the inner corner trim mould is hinged forms by backform with a pair of, going up oblique oil cylinder is connected between backform and the last inner corner trim mould, oblique oil cylinder is connected between inner corner trim mould and the following inner corner trim mould down, be interval with bracing frame in the cavity bottom central authorities that inner formword is enclosed along case beam depth, set up rail on the bracing frame, walking translation dolly on the rail, the translation dolly comprises travelling wheel, a vehicle frame and a seat beam that is fixed on the vehicle frame, the vehicle frame of translation dolly extends to outside the inner formword, lays hydraulic power unit and operating desk on it.The present invention is simple in structure, and steel using amount is few, and is with low cost, uses simple to operate, translation dolly whole walk, made things convenient for the integral body discrepancy of internal mold.3, " the all-hydraulic whole deploying and retracting internal mold of high-speed railway Line for Passenger Transportation prefabricated case beam " application (patent) number CN200620134016.2 way is: the all-hydraulic whole deploying and retracting internal mold of high-speed railway Line for Passenger Transportation prefabricated case beam, belong to the site operation apparatus field, include the backform that places the middle part, two side forms that are positioned at both sides and are hinged with backform, the side form below has the hinged angle mould of bearing pin respectively, be provided with hydraulic jack between its backform and the side form, also be provided with hydraulic jack between side form and the angle mould, the top, side, the middle part of the re-entrant cavity that angle mould forms is provided with away cross girders, it is supported on the special shoulder pole type case beam in baseplane by roller, and is provided with anchoring rod between the baseplane.The installation of inner membrance, shift out operation and simplify, simplified supporting form in the beam simultaneously, adopt the hydraulic pressure folding and retraction, needn't manually fold, pass through hydraulic-driven, template reaches the purpose of reduced volume with folding mode, the small space that overall time forms because of thickening web, top board and base plate at beam-ends by the case beam.4, " box girder inner formwork " application (patent) number CN 200720089937.6 the invention discloses a kind of box girder inner formwork, its top template two side ends is hinged with the upper end of an epipleural respectively, the lower end of two epipleurals is hinged with the upper end of a lower side panel respectively, vertically whenever keep at a certain distance away along described top template a upright beam and jacking cylinder are set, all jacking cylinders upper end all with described top template longitudinal centre line on soffit hinged, all jacking cylinder lower ends are installed on separately the upright beam, be provided with guide rail and roller between all upright beams and the support, top template vertically some horizontal tangent planes is provided with, following telescopic oil cylinder, last telescopic oil cylinder is arranged between top template and the epipleural, following telescopic oil cylinder is arranged between epipleural and the lower side panel, top template vertically some horizontal tangent planes is provided with, lower supporting rod, last strut is arranged between top template and the lower side panel, and lower supporting rod is arranged between epipleural and the upright beam.The present invention is simple in structure, have the advantage that system beam speed is fast, labour intensity is little, mechanization degree is high.
Yet these four patents have all adopted the hydraulic jack system, though a series of advantage is all arranged, at external mold Zhi Haohou, the remaining space in the external mold is limited, so concrete execution conditions are limited, as: the people can't enter at all, equipment also can't set up.For the narrow and small case beam of clear space in the beam body, especially be subjected to the restriction of equipment volume, hydraulic mechanism size, above-mentioned patented method and structure are inapplicable.
