Embodiment Construction

[0036] The embodiment of the present invention solves the shortcomings of the mandrel of the prefabricated hollow slab girder in the prior art by providing a mechanical demoulding device for the steel mandrel of the prefabricated hollow slab girder, and realizes the technical effect of conveniently installing and removing the steel formwork.

[0037] The technical solution in the embodiment of the present invention is to solve the above-mentioned shortcomings. The general idea is as follows: the support frame is placed in the hollow position of the prefabricated hollow slab beam, and the telescopic device is used to cooperate with the limit rope and the limit rod to install the steel formwork and the detachment rod in an orderly manner. Each telescopic device controls the movement of two steel formworks. When the steel formwork is unfolded, a steel core mold is formed. When the steel formwork is retracted, it is demoulding. After demoulding, the support frame can be directly ext...

Abstract

The invention provides a mechanical demolding device for a steel core mold of a prefabricated hollow slab beam, and relates to the technical field of highway engineering. The mechanical demolding device comprises a support frame, a first base, a first expansion device, a first limiting rope and a first limiting rod, wherein the first base is connected with the support frame in a sliding manner and is also fixedly connected with a sheet steel form; the first expansion device is provided with a first shell and a first movable rod, the first shell is fixedly connected with the first base, and the first movable rod is fixedly connected with another sheet steel form; the two ends of the first limiting rope are fixedly connected with another sheet steel form and the support frame respectively; and the first limiting rod is fixedly connected with the support frame and can abut against another sheet steel form. The mechanical demolding device has the advantages that the support frame is placed at the hollow position of the prefabricated hollow slab beam, the sheet steel forms are automatically installed and demolded through the expansion devices, the support frame is directly drawn after demolding, each expansion device correspondingly controls the movement of the two sheet steel forms, and the sheet steel forms are conveniently installed and dismantled.

Description

technical field [0001] The invention relates to highway engineering, in particular to a mechanical demoulding device for a prefabricated hollow slab girder steel mandrel. Background technique [0002] At present, the mandrels of prefabricated hollow slab beams mainly include: wood formwork mandrels, rubber airbag mandrels, foam mandrels, steel mandrels, etc. Wooden formwork mandrels are complicated to make, difficult to demould, and low turnover rate; rubber airbag mandrels have low rigidity, are easy to shift and float up, resulting in large size differences, which do not meet the design requirements, and rubber airbag mandrels are punctured, easily causing quality accidents . At present, the rubber airbag mandrel has been listed as an obsolete process. The foam mandrel is suitable for special parts that do not need to be dismantled. The existing steel mandrel is cumbersome to operate and difficult to install and remove. Contents of the invention [0003] The technica...
