Description
Technical field
The utility model relates to prefabricated case beam outside moulding/demoulding and formwork erection device, and refering in particular to is outer side form hydraulic ejection of a kind of prefabricated case beam and formwork erection device.Belong to concrete cast equipment technical field.
Background technology
During prefabricated case beam, template need be in place by design size, be called formwork erection; Prefabricated case beam cast and solidify after, form removable need be called the demoulding.Referring to accompanying drawing 1, the knockout course of the outer side form of traditional prefabricated case beam is: case is beam prefabricated finish after, the workman is located at the jack 10 of the vertical direction on the split heads by operation, outer side form is descended at vertical direction, 8 on the traversing support that is installed on the outer side form contacts with traveling dolly 12, and the weight of outer side form is all supported by traveling dolly 12; Then, the jack 11 of the horizontal direction between traversing support 8 and the traveling dolly 12 is located in operation, and the traversing support of jack 11 pushing tows makes traversing support and the outside traversing slip on traveling dolly 12 simultaneously of outer side form, realizes the demoulding; At last, by hoist engine traction traveling dolly 12, the vertical shift of traction external mold is to other beam making bench.This stripping means, outer side form descend and during the traversing demoulding, need operate jack simultaneously by several workmans, and all be workman's manual operations, and not only labour intensity is big, and production efficiency is low, and be time-consuming and security is low, and security incident takes place easily.
The utility model content
It is a kind of simple and reasonable, easy to operate that the purpose of this utility model is to provide, and formwork erection, is convenient in demoulding outer side form hydraulic ejection of good, the labor-saving prefabricated case beam of security and formwork erection device.
The utility model is realized by following proposal: outer side form hydraulic ejection of prefabricated case beam and formwork erection device, be the jacking cylinder that side form vertical rack and the back of the body are provided with vertical direction on the frame respectively outside prefabricated case beam, the piston of described jacking cylinder can extend out to above the traveling dolly of being located under the described outer side form; Outside described side form bottom be provided with described outside the side form traversing support of fixedlying connected; On described traversing support, be provided with the translation oil cylinder of horizontal direction, an end of described translation oil cylinder be located at described outer side form under the traveling dolly on the ear seat be connected, the other end is connected with traversing support; Side form is provided with the hydraulic power unit that is connected with described jacking cylinder and described translation oil cylinder outside.
In the utility model, described traveling dolly bottom is provided with travelling wheel, and described travelling wheel is installed on the peripheral hardware longitudinal translation track.
Operation principle of the present utility model and advantage are sketched in following:
Prefabricated case beam cast and solidify after, when needing form removal, earlier operating hydraulically operated pumping plant make the piston of jacking cylinder be stretched to be located at described outer side form under the traveling dolly contact after, stop action, at this moment, the weight of outer side form is all supported by the traveling dolly, then, is used to support the jack of outer side form when removing the prefabricated case beam cast; After the jack complete removal of side form finishes outside supporting, operating hydraulically operated pumping plant 5 makes jacking cylinder 4 piston retraction, drive outer side form in the whole decline of vertical direction by jacking cylinder 4 piston retraction, the traversing support that is provided with until outer side form bottom contacts with the traveling dolly, and outer side form stops to descend; Continue to shrink the jacking cylinder piston, the jacking cylinder piston is separated with the traveling dolly; Then, operating hydraulically operated pumping plant drives translation oil cylinder and stretches out, because translation oil cylinder one end is fixed on the traversing support of being located at described outer side form bottom, the other end is connected on the traveling dolly, therefore, make the outside translation of described outer side form of fixedlying connected when translation oil cylinder stretches out, realize the traversing demoulding with described traversing support; Traveling dolly bottom is provided with the structure of travelling wheel, when outer side form after finishing the traversing demoulding on the traveling dolly, can be easily by hoist engine traction traveling dolly and outer side form along the vertical shift of peripheral hardware longitudinal translation track to other beam making bench.Formwork erection step before the prefabricated case beam cast is opposite with demoulding step.After adopting this device, only need workman's operation can realize the formwork erection and the demoulding of outer side form, effectively reduce labor strength, raise labour productivity, shorten the prefabricated cycle of prefabricated case beam, security is good.
In sum, the utility model is simple in structure, and is easy to operate, formwork erection, be convenient in demoulding conveniently, can effectively reduce labor strength, raise labour productivity, shorten the prefabricated cycle of prefabricated case beam, be suitable for suitability for industrialized production, can be applicable to prefabricated case beam formwork erection, the demoulding of various models.
