Problems solved by technology

[0003] When the concrete components are prefabricated in the factory, after the concrete curing is completed, the concrete needs to be demoulded. The existing method of demoulding the concrete formwork is manual knocking, which requires multiple knocks to achieve demoulding, and the manual workload is relatively large.

Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, the demoulding device for assembled concrete members in this embodiment includes a cylindrical demoulding cylinder, a handrail 9 is fixed on the top of the demoulding cylinder, and a hook 15 is welded on the bottom of the demoulding cylinder. Be fixed with handle 13 and be convenient to portable carrying. A baffle 3 is fixed inside the demoulding cylinder, and the baffle 3 divides the demoulding cylinder into an upper cylinder 2 and a lower cylinder 1 .

[0033] The lower cylinder 1 is provided with a cylindrical impact piece 4, and a spring 14 is fixed between the impact piece 4 and the inner bottom of the lower cylinder 1. The spring 14 is a compression spring. Determined after calculation. Two demoulding rods 40 are fixed on the outer wall of the impact part 4, and the two demoulding rods 40 are arranged axially symmetrically with respect to the impact part 4, and the lower cylinder body 1 is provided with two lower axial s...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that: image 3 and Figure 4 As shown, the structure of the lever-type demoulding driver in this embodiment is different from that of Embodiment 1. In this embodiment, the sliding sleeve 10 and the connecting rod 7 in the lever-type demoulding driver are located inside the upper cylinder 2, and hit There is no demoulding rod 40 on the side wall of part 4, and there is no lower axial strip hole 5 on the side wall of lower cylinder 1. In this embodiment, the worker applies force to the free end of the pressure rod 8. Since the ratio between the force arm at the force applied by the worker's hand and the force arm at the force applied by the sliding sleeve 10 is larger than that in Embodiment 1, the present embodiment Compared with Embodiment 1, it is more labor-saving.

Embodiment 3

[0043] The difference between the present embodiment and the second embodiment is that: Figure 5 As shown, in this embodiment, the number of 8 pressing rods is one, and the connection between the pressing rod 8 and the striking member 4 is located at the center of the top of the striking member 4 . Only one pressing rod 8 is used to drive the movement of the connecting rod 7 , since the force application point of the connecting rod 7 to the striking part 4 is located at the center of the top of the striking part 4 , the force on the striking part 4 can also be made stable.

Abstract

The invention belongs to the field of auxiliary equipment for the production of assembled building components, and specifically discloses a demoulding device for fabricated concrete components, which includes a demoulding cylinder, a hook is fixed on the bottom of the demoulding cylinder, and a baffle is fixed inside the demoulding cylinder, and the baffle will The demoulding cylinder is divided into an upper cylinder and a lower cylinder; the lower cylinder is equipped with an impact piece, and a spring is fixed between the impact piece and the bottom of the lower cylinder; the upper cylinder is equipped with a lever for driving the impact piece to move up and down in the lower cylinder Type ejection drive. The present invention uses the huge elastic restoring force generated when the compressed spring returns to its original shape to drive the striking part to hit the baffle, thereby pulling the entire demoulding cylinder, and the hook of the demoulding cylinder exerts force on the formwork, so there is a pulling force on the formwork Function, so as to achieve automatic demoulding, instead of the existing manual knocking to achieve demoulding, reducing the manual workload.

Description

technical field [0001] The invention relates to the field of auxiliary production equipment for assembled building components, in particular to a demoulding device for assembled concrete components. Background technique [0002] Prefabricated buildings are buildings in which beams, columns, wall panels, balconies, stairs and other components are pre-produced in the factory, and then transported to the construction site for assembly. Prefabricated concrete components are used for assembly construction, which has the advantages of saving labor, overcoming seasonal influences, and facilitating construction all year round. [0003] When prefabricating concrete components in the factory, after the concrete curing is completed, the concrete needs to be demoulded. The existing operation method for demoulding the concrete formwork is manual knocking, which requires multiple knocks to achieve demoulding, and the manual workload is relatively large. Contents of the invention [000...
