Description

Novel portable hydraulic pressure little case roof beam external mold
Technical Field
The invention discloses a novel movable hydraulic small box girder external mold, and particularly relates to the technical field of bridge construction industry.
Background
With the rapid development of bridge construction, the box girder construction process is in step with standardized construction. The system roof beam template of traditional concrete box girder is mostly the pin-connected panel, mainly adopts the mode that the combination steel mould loosed to assemble to be under construction promptly, and the advantage of adopting the pin-connected panel template is that design, manufacturing are more convenient, and the cost is lower. The box girder mold is widely applied to the box girder production and manufacturing industry as a tool for producing and manufacturing the box girder. The box girder is one of the middle girders in bridge engineering, the inner part of the box girder is hollow, and flanges are arranged on two sides of the upper part of the box girder and are similar to a box, so that the box girder is named. However, when two pedestals of the conventional prefabricated small box girder share the outer mold, the outer mold is disassembled after the prefabrication is completed, and then the two pedestals are assembled on the other pedestal. However, the length of the small box girder is generally more than 20m, the template cannot be integrally hoisted, and the template can only be disassembled and assembled between the two pedestals back and forth. Therefore, a large amount of manpower and material resources are wasted in the disassembly and assembly of the template, the construction period is prolonged, the probability of damaging the surface of the template is increased in the process of back-and-forth lifting of the box girder outer mold between two box girder pedestals in common use at present, the template is rocked back and forth during lifting, and certain personal risks are brought to constructors.
When two pedestals of the conventional small prefabricated box girder share the outer mold, the outer mold is disassembled after the prefabrication is completed, and then the small prefabricated box girder is assembled on the other pedestal. However, the length of the small box girder is generally more than 20m, the template cannot be integrally hoisted, and the template can only be disassembled and assembled between the two pedestals back and forth. Therefore, a large amount of manpower and material resources are wasted in the disassembly and assembly of the template, the construction period is prolonged, the probability of damaging the surface of the template is increased in the process of back-and-forth lifting of the box girder external mold between two box girder pedestals in common use at present, and the template swings back and forth during lifting, so that certain personal risks are brought to constructors, and the method is disclosed in Chinese patent publication No.: CN 208455446U a span precast box girder varies, the precast box girder is striden unequally, and the precast pedestal construction is the trapezoidal face of falling, and the side slope of precast pedestal and the web slope of box girder unanimously to set up the pull rod preformed hole in the precast pedestal, can calculate the position of pull rod preformed hole according to different roof beam heights. When box girders with different girder heights are prefabricated, the box girder outer template can be moved up and down to a proper position, and the lateral baffle is moved according to the length of the movable wing plate, so that the box girders with different spans can be prefabricated by sharing one set of template pedestal, the land investigation in a prefabricated field is reduced under the condition that the geometric dimension of the box girders with different spans is basically constant, the construction cost is reduced, the construction progress is accelerated, and a good application scene is realized. But the small box girder template needs to be dismounted repeatedly without hoisting in the construction project, and the problem of realizing the movable mounting and dismounting of the whole template is still not well applied in the existing building field and bridge construction.
When two pedestals of the conventional small prefabricated box girder share the outer mold, the outer mold is disassembled after the prefabrication is completed, and then the small prefabricated box girder is assembled on the other pedestal. However, the length of the small box girder is generally more than 20m, the template cannot be integrally hoisted, and the template can only be disassembled and assembled between the two pedestals back and forth. Therefore, a large amount of manpower and material resources are wasted in the disassembly and assembly of the template, the construction period is prolonged, the probability of damaging the surface of the template is increased in the process of back-and-forth lifting of the box girder external mold between two box girder pedestals in common use at present, and the template swings back and forth during lifting, so that certain personal risks are brought to constructors, and the method is disclosed in Chinese patent publication No.: the invention provides a CN 203125676U common template and pedestal for box girders with different spans, which comprises a box girder inner film and a box girder outer film matched with an inner film. According to the technical scheme, the outer die is integrally slid up and down by abutting against the pedestal, box girders with different spans and different web heights are constructed, but hoisting and repeated disassembly are not needed in the construction of small box girder templates, and the problem of moving, installing and disassembling the whole templates is solved in the existing building field and the bridge construction.
