Description
Technical field
The utility model relates to a kind of bridge construction accessory, is specifically related to a kind of prefabricated small box girder internal mould device.
Background technology
Prefabricated case beam is generally used in the middle of bridge, and prefabricated case beam is exactly first carry out stretch-draw and flexural member prefabricated in advance by pre-tensioning system or post stretching to reinforcing bar, then transport to job site installing.
Production Small Precast Box beam method is: on production pedestal, assemble framework of steel reinforcement, install internal mold, external mold, build, maintenance, tension, facilitate to be installed.Existing prefabricated small box girder cast outer mold structure such as patent publication No. is CN103774561A, patent name is for shown in the Chinese invention patent of " job execution of highway prefabricated small box girder frock method streamlined ", as can be seen from description and accompanying drawing 7, its internal mold is by internal mold top plate, interior baffle plate, and the left template of mutual specular and right template composition in structure, left template is made up of the upper left template be hinged and lower-left template, upper left template and lower-left template are connected with dismountable left connecting plate, left connecting plate is used for the relative position of fixing upper left template and bottom right template, connected by screw rod between left connecting plate and right connecting plate, lower-left template and bottom right template also have screw rod to be connected.When small box girder has been built, after box girder integral structure basic forming, rotate screw rod, left template and right template are furthered.Diminishing of inner formword, is separated with case beam, is finally pulled out by inner formword with hoist engine.In said structure, inner formword is all pure manual operation, not only inefficiency with being separated of case beam, and increases the labour intensity of workman.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of prefabricated small box girder internal mould device.
The utility model solves the technical scheme that its technical problem adopts:
A kind of prefabricated small box girder internal mould device, comprise internal mold top plate, symmetrical left template and right template in interior baffle plate and structure, described left template comprises upper left template, lower-left template and left plate, upper left template and lower-left template are hinged on the two ends of left plate respectively, left telescoping cylinder is connected with between upper left template and lower-left template, described right template comprises upper right template, bottom right template and right plate, upper right template and bottom right template are hinged on the two ends of right plate respectively, right telescoping cylinder is connected with between upper right template and bottom right template, the bottom of described internal mold is provided with internal mold sliding seat, left, right template telescopically is arranged on the top of internal mold sliding seat, left, transversal stretching cylinder is connected with between right template.
In the utility model, between described upper left template, upper right template and internal mold top plate, be provided with top support plate.
In the utility model, between described lower-left template and left plate, between bottom right template and right plate, be equipped with rotary limit device.
The beneficial effects of the utility model are: the utility model is supporting complete hydraulic operating system on the basis of traditional internal mold, the dismounting of internal mold and be fitted through hydraulic system contraction, uphold and control, solve the potential safety hazard that small box girder internal mold may cause by manual work.The receipts mold process of internal mold divides three steps, and the first step rotates to receive mould, makes upper left, lower-left, upper right, the bottom right template demoulding; Second step is that mould is received in translation, makes the demoulding of arranged on left and right sides template; 3rd step utilizes external force traction that internal mold is hauled out beam body.When template front end runs to small box girder inner chamber base plate variable cross-section place, each telescoping cylinder can be adjusted successively by hydraulic system, make internal mold maintenance level and maximum appearance and size is less than the inner cavity size of beam body end portion, repeat a whole set of operation until internal mold is removed complete.
