Description
Technical field
The present invention relates to a kind of combined box beam hydraulic internal mold.
Background technology
At present, domestic railway, highway and Urban Bridge are taken as the leading factor with reinforced concrete structure, and bridge deck unit adopts prefabrication system to make basically.To make concrete box girder is example, and all templates are made up of internal mold, external mold, bed die, end mould and console.General case beam inner chamber design size be broad in the middle, that two is little is horn-like; Master operation has mould assembly unit, grouting, shifting formwork etc.; Internal mold needs artificial unloading's telescopic strut before receiving mould and since inner chamber at the end section place size decreases, cause workman's working space little; And before the internal mold shifting formwork, must lay the walking rails of hauling out internal mold, more strengthen labour intensity.Especially as this combined box beam of logical bridge (2008) 2227A type, it is little that its case beam itself has an intracavity space, characteristics such as beam body section vary within wide limits, thereby more difficult prefabricated efficient and the quality that realizes through hydraulic pressure whole demoulding raising case beam.
Summary of the invention
Even the object of the present invention is to provide the combined box beam hydraulic internal mold that also can realize the whole demoulding of hydraulic pressure in a kind of beam type of, beam body section vary within wide limits little at intracavity space.
This combined box beam hydraulic internal mold provided by the invention comprises template, guide pillar, girder, base for supporting, and said template links to each other with guide pillar through adjustable column; Be equipped with guide pin bushing in the said girder; The girder bottom is equipped with guide rail, and said guide pillar is installed in this guide pin bushing and can slides within it, and anti-roller is installed on the said base for supporting; Said girder bears on this anti-roller and can slide above that through guide rail hauls out the beam body with internal mold; Said template includes top board, last dynamic model, following dynamic model and top board longeron, and top board longeron and top board are welded as a whole, and are used to strengthen top board rigidity; Template is divided into end section and middle section, in end section, is connected through articulated manner between top board and the last dynamic model, and the side direction oil cylinder is arranged between top board and the last dynamic model; In the middle section, be connected through the four-bar linkage mode between top board and the last dynamic model, the side direction oil cylinder is arranged between top board longeron and the last dynamic model; In end section and middle section, all adopt articulated manner to be connected between last dynamic model and the following dynamic model, be furnished with the side direction oil cylinder between the two; Be connected with telescopic strut between top board and the base for supporting, be used to prevent the template come-up; Be connected with between said guide pillar and the girder and be used to drive the jacking cylinder that template rises or descends.
Telescopic strut is connected between girder and the last dynamic model, between girder and the following dynamic model, be used for strengthening each formwork rigidity.
Internal mold of the present invention is provided with guide rail on girder, deducted the step of other laying shifting formwork track, has improved operating efficiency.And, each sections template all can be satisfied receive the mould requirement because the template of diverse location has been adopted different receipts mould modes.The present invention has operation, easy to use, and case beam Forming Quality is good, and stripping rate is fast, characteristics such as production efficiency height, and use is gone up in the box girder inner formwork design that is adapted at same kind.

The specific embodiment
As can beappreciated from fig. 1; This combined box beam hydraulic internal mold of the present invention; Comprise template 1, adjustable column 2, guide pillar 3, girder 4, base for supporting 5, telescopic strut 6, jacking cylinder 7 and side direction oil cylinder 8; Be equipped with guide pin bushing 41 in its middle girder 4, its bottom is equipped with guide rail 42, and anti-roller 51 is installed on the base for supporting 5.Template 1 links to each other with guide pillar 3 through adjustable column 2; Guide pillar 3 is installed in the guide pin bushing 41 in the girder 4 and can slides within it; The guide rail 42 of girder 4 through the bottom bears on the anti-roller 51 of base for supporting 5 and can slide above that hauls out the beam body with internal mold; Jacking cylinder 7 is connected between guide pillar 3 and girder 4, is used to drive template 1 and rises or descend.
Can find out that from Fig. 2 to Fig. 5 template 1 can be divided into top board 11, last dynamic model 12, following dynamic model 13 and top board longeron 14.As can beappreciated from fig. 1, template of the present invention can be divided into end section and middle section.In end section, be connected through articulated manner between top board 11 and the last dynamic model 12, side direction oil cylinder 8 is arranged between top board 11 and the last dynamic model 12; In the middle section, be connected through the four-bar linkage mode between top board 11 and the last dynamic model 12, the side direction oil cylinder is arranged between top board longeron 14 and the last dynamic model 12; In end section and middle section, all adopt articulated manner to be connected between last dynamic model 12 and the following dynamic model 13, be furnished with side direction oil cylinder 8 between the two.
As can beappreciated from fig. 2, telescopic strut 6 is connected between girder 4 and the last dynamic model 12, between girder 4 and the following dynamic model 13, be used for strengthening each formwork rigidity.As can beappreciated from fig. 4, telescopic strut 6 is connected between top board 11 and the base for supporting 5, is used to prevent the template come-up.
Middle girder of the present invention 4, guide pin bushing 41, guide rail 42; It is the main bearing carrier of whole template; It bears the deadweight of whole box girder inner formwork and the active force that cast concrete is produced; And through base for supporting power is passed to bed die and beam making bench basis, make internal mold whole stressed evenly, good stability.
During formwork erection of the present invention; Through each oil cylinder of HYDRAULIC CONTROL SYSTEM, stretch out jacking cylinder 7 piston rod pushing tow guide pillars 3, put template 1 jacking in place (being that the internal mold overhead height reaches construction requirement); The last dynamic model 12 that promotes each cross section successively through each side direction oil cylinder 8 of HYDRAULIC CONTROL SYSTEM again and following dynamic model 13 are until the degree that opens up into designing requirement; Telescopic strut 6 is installed then,, is strengthened formwork rigidity with the fixed form position.This moment, internal mold was in the state of upholding fully, kept this state can carry out the concrete cast, like Fig. 2 and shown in Figure 4.
During the demoulding of the present invention, remove telescopic strut 6 earlier, draw dynamic model 13 and last dynamic model 12 under each cross section successively in, shrink jacking cylinder again, make whole template drop to design height, like Fig. 3 and shown in Figure 5 through HYDRAULIC CONTROL SYSTEM side direction oil cylinder.After shrinking the template completion, can internal mold be shifted out in the precast beam of having poured into a mould through outside elevator machine travel.
