Method and equipment for recovering main reinforcing bar in concrete beam

Abstract

The invention relates to a method and equipment for recovering a main reinforcing bar in a concrete beam. The method comprises the following steps of first, crushing the concrete beam by using a crusher; then further rolling and crushing the concrete beam by a rolling crusher and clipping a stirrup; outputting the crushed concrete blocks and clipped stirrups by a waste output machine in a centralized manner; and finally, clipping the main reinforcing bar cleaned by the main reinforcing bar clipping machine as needed and covering the main reinforcing bar in a centralized manner, wherein the utilization ratio is improved. By adopting automatic equipment, the main reinforcing bar with the highest recycling value in the concrete beam is crushed and dismantled efficiently and are clipped in a centralized manner, so that the main reinforcing bar is recycled efficiently and therefore, the recycling rate of the concrete beam is improved. The equipment for recovering the main reinforcing bar inthe concrete beam is designed by using modular equipment, and is convenient to manufacture and assemble and convenient and reliable to maintain daily.

Description

technical field [0001] The invention relates to an invention for crushing concrete beams and cutting main steel bars in them as required to improve recycling and special equipment. Background technique [0002] In the field of construction, concrete beams are often used, because steel bars are generally used as internal supports, and then concrete is poured and formed by condensation. When the building is demolished, the concrete beam is difficult to be broken by ordinary demolition equipment due to its firm structure. [0003] At present, there are some professional equipment for crushing concrete beams, such as the pre-breaking device for reinforced concrete beams with the Chinese Patent Publication No. CN107008560A applied by the applicant, which uses a special working head to carry out static pressure shearing and crushing of concrete. Broken, the concrete is quickly broken and dropped, and separated from the internal steel bars, which is convenient for transportation a...

Problems solved by technology

[0005] However, since the main steel bars in concrete beams have high strength and high value, if they can be recycled separately, the recycling value can be improved; but the current crushing devices are all focused on the crushing of concrete blocks, and there is no effective way for internal steel bars. Only messy rebar clusters or scraps of rebar can be formed
