Compared with the cast-in-situ construction method, the fabricated concrete structure is beneficial to green construction, because the fabricated construction can better meet the requirements of land saving, energy saving, material saving, water saving, environmental protection and the like of green construction, reduce the negative influence on the environment and follow the principle of sustainable development.
Since the quality of precast concrete members depends on the quality of the form to a great extent and the required amount is generally large, steel forms are generally used in the present stage to save the cost and simultaneously meet the requirements, but the operations during form removal are relatively complex and various problems are easy to occur.
At present, the prefabricated concrete member is disassembled by mainly impacting the flange of the member template from top to bottom by manually using a crowbar, a hammer and the like, so that the purpose of demolding is achieved, but the manual demolding mode has the following problems: 1) The demolding modes such as a crow bar, a hammer and the like directly impact the mold flange can influence the strength and rigidity of the mold, and the mold can be expanded and deformed when serious, so that the turnover frequency of the mold is influenced, and the quality of a finished product of a prefabricated part is also influenced; 2) The crow bars are used for being hard , which is easy to damage corners of concrete members, in addition, the precast concrete members are often provided with pre-buried pipelines, the reserved pipelines can be flattened and cannot be threaded due to the fact that the reserved pipelines are hard , and when the reserved pipelines are severe, only grooving and pipe replacement are carried out, so that the waste of materials and labor cost is very high; 3) The manual die stripping efficiency is low, and the labor consumption is increased; 4) In addition, for small-sized cavity components, an inner cavity template is arranged besides the side mold, and the concrete is expanded due to the fact that certain heat is generated during the hydration reaction of the concrete, so that the inner cavity mold is easy to clamp, the demolding is difficult, and the components are damaged due to violent demolding.
The prior patent 202222423871.7 discloses a precast concrete member shedder, including the fixing base, fixing base top fixed mounting has the mould, and the inside movable mould board that is provided with of mould is provided with the fixed slot on the mould, is provided with the through-hole on the movable mould board, and the inside bolt that is provided with of through-hole, mould inner wall are provided with dull and stereotyped vibrator, and fixing base inside fixed mounting has electronic cylinder, and electronic cylinder top is provided with the movable column, and movable column top fixed mounting has the support sealing piece, and mould inner wall bottom is provided with the seal groove, and the fixing base bottom is provided with the dashpot. The utility model has higher demoulding efficiency and convenient operation, can effectively buffer and absorb shock when in work, and improves the stability of the whole device; but the structure is complex, electric drive is needed, and the subsequent maintenance cost is high.
Disclosure of Invention
