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 substantially.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, because inner chamber is in 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 realization is by the prefabricated efficient and the quality of hydraulic pressure whole demoulding raising case beam.
The utility model content
Even the purpose of this utility model 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 that the utility model provides, comprise template, guide pillar, girder, base for supporting, described template links to each other with guide pillar by adjustable column, be equipped with guide pin bushing in the described girder, its bottom is equipped with guide rail, described guide pillar is installed in this guide pin bushing and can slides within it, and anti-roller is installed on the described base for supporting, and described girder bears on this anti-roller and can slide thereon by guide rail hauls out the beam body with internal mold.
Described template includes top board, last dynamic model, following dynamic model and top board longeron, top board longeron and top board are welded as a whole, be used to strengthen top board rigidity, described top board is connected with last moving platen by four-bar linkage mode or articulated manner, be used to drive the side direction oil cylinder that dynamic model moves being equipped with between top board and the last moving platen or between top board longeron and the last dynamic model, the described dynamic model of going up is connected with following dynamic model by articulated manner, be equipped with between last dynamic model and the following dynamic model be used to drive under the side direction oil cylinder of dynamic model rotation.
Be connected with between described guide pillar and the girder and be used to drive the jacking cylinder that template rises or descends.
Be connected with telescopic strut between described top board and the base for supporting, be used to prevent the template come-up.
Be connected with telescopic strut between described template and the girder, be used for strengthening each formwork rigidity.
The utility model internal mold 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 utlity model has operation, easy to use, 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 be seen from Figure 1, this combined box beam hydraulic internal mold of the utility model, 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 by 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 by the bottom bears on the anti-roller 51 of base for supporting 5 and can slide thereon 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.
As can be seen, template 1 can be divided into top board 11, last dynamic model 12, following dynamic model 13 and top board longeron 14 from Fig. 2 to Fig. 5.As can be seen from Figure 1, the utility model template can be divided into end section and middle section.In end section, be connected by 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 by 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 be seen from Figure 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 be seen from Figure 4, telescopic strut 6 is connected between top board 11 and the base for supporting 5, is used to prevent the template come-up.
The utility model middle girder 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 power is passed to bed die and beam making bench basis by base for supporting, make internal mold whole stressed even, good stability.
During the utility model formwork erection, by 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), promote the last dynamic model 12 in each cross section and following dynamic model 13 successively until the degree that opens up into designing requirement by each side direction oil cylinder 8 of HYDRAULIC CONTROL SYSTEM again, 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, as Fig. 2 and shown in Figure 4.
During the utility model demoulding, 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, as Fig. 3 and shown in Figure 5 by HYDRAULIC CONTROL SYSTEM side direction oil cylinder.After the contraction template is finished, internal mold can be shifted out in the precast beam of having poured into a mould by outside elevator machine travel.
