Automatic demolding mechanism for concrete prefabricated part and using method of automatic demolding mechanism

Abstract

The invention relates to the field of concrete pouring, in particular to an automatic demolding mechanism for a concrete prefabricated part and a using method of the automatic demolding mechanism. The automatic demolding mechanism comprises a base system, a self-climbing system, contraction systems, a top cover system and a formwork system; the base system is arranged at the bottom of the formwork system, the top cover system is arranged at the top of the formwork system, and the contraction systems are arranged on the two sides of the formwork system; and the base system is used for supporting and adjusting the whole mechanism, the self-climbing system is matched with the base system to be used for lifting the whole mechanism, the contraction systems and the formwork system are used for inward contraction and outward supporting of a formwork during demolding, and the top cover system is used for internal protection and concrete leading-in during pouring. The contraction system with a dual-drive power mechanism compatible with internal drive and external drive is adopted, so that the operation of a worker above the top cover system can be realized, and the operation of the worker in a mechanism operation cavity can also be realized.

Description

technical field [0001] The invention relates to the field of concrete pouring, in particular to an automatic demoulding mechanism for a concrete prefabricated part and a using method thereof. Background technique [0002] When pouring concrete with internal holes (septic tanks, pipe wells, piers with internal holes, elevator shafts, etc.), the demoulding of the internal holes of the building needs to be completely dismantled, the construction is cumbersome, and the shape and precise size must be guaranteed when forming the mold difficulty. For the one-piece shrinkable demoulding mechanism, the locking and holding force is poor. If there is no self-locking mechanism, it will loosen after a long period of vibration, resulting in a reduction in the molding size; moreover, special fasteners are required for the connection between the template and the driving mechanism, which is poor in versatility and fixed.

Problems solved by technology

[0002] When pouring concrete with internal holes (septic tanks, pipe wells, piers with internal holes, elevator shafts, etc.), the demoulding of the internal holes of the building needs to be completely dismantled, the construction is cumbersome, and the shape and precise size must be guaranteed when forming the mold difficulty

For the one-piece shrinkable demoulding mechanism, the locking and holding force is poor. If there is no self-locking mechanism, it will loosen after a long period of vibration, resulting in a reduction in the molding size; moreover, special fasteners are required for the connection between the template and the driving mechanism, which is poor in versatility and fixed. Trouble; and the demoulding shrinkage driving method is single, and the demoulding cannot be driven from the inside; the lifting needs to be hoisted by external force, and the stability is poor. The lifting of the crane cannot have a large load, and there are strict requirements on the weight of the mechanism itself
