Description

Shaping device for recycled concrete preparation Technical Field The invention relates to the technical field of concrete shaping, in particular to a shaping device for preparing recycled concrete. Background The waste concrete is crushed, screened and cleaned to prepare recycled aggregate, and the recycled aggregate is used for prefabricating road isolation piers, so that not only can large amount of solid waste of disassembly and construction be consumed, but also natural sand and stone exploitation can be reduced, and carbon emission and material cost are obviously reduced. The recycled concrete precast hard shoulder needs to be poured, shaped and demoulded quickly in a factory and then transported to the site for installation. The production process generally adopts a shaping die made of steel, and realizes batch prefabrication by die cavity molding, vibrating compaction, overturning and demoulding after curing hardening. The mould is used as a key tool for forming the recycled concrete hard shoulder, has the functions of bearing, shaping and transferring, can be generally recycled hundreds to thousands of times, and is matched with procedures such as overturning, stacking, hoisting and the like to form a high-efficiency prefabricated production line. After the hard shoulder shaping mould fully loads concrete, the whole dead weight often reaches hundreds of kilograms, often the hard shoulder shaping mould is pushed by a crown block or a forklift to overturn and demould, the impact peak value of the ground is required to be several times of the static load in the moment, the hard shoulder shaping mould can not be effectively buffered when the hard shoulder shaping mould is overturned and demoulded, the impact is easy to crush the local terrace, the pier body with lower early strength of recycled concrete is easy to generate surface microcracking and root dark cracking, the cracks are rapidly expanded after the subsequent freeze thawing cycle, the service life is reduced, and the traditional mould is often separated only by falling under the dead weight after being overturned, the recycled concrete is strongly bonded by an aggregate interface, the phenomenon of sticking is often caused, the side plate is required to be manually knocked repeatedly, and microcracks are further induced by frequent knocking vibration, so that the quality vicious cycle is formed. Disclosure of Invention The invention aims to solve the problems that the overturning and demolding impact force of a shaping mold is large but cannot be effectively buffered, and a concrete precast block is separated by only falling under dead weight after overturning, so that a finished product is easy to be stuck with the mold, cracked and the like.
