Concrete inner support support-free dismantling device and dismantling method
The invention discloses a support-free dismantling device and dismantling method for a concrete inner support. The support-free dismantling device comprises a supporting main beam dismantling assembly used for dismantling a supporting main beam and a supporting secondary beam dismantling assembly used for dismantling a supporting secondary beam. The supporting secondary beam dismantling assembly comprises a pulling mechanism and hanging rings, the pulling mechanism is pulled between adjacent supporting secondary beam sections to be dismantled and supporting secondary beam sections not to be dismantled, the hanging rings are pre-buried on a supporting secondary beam, and each supporting secondary beam section to be dismantled is provided with one hanging ring; the supporting main beam dismantling assembly comprises a cantilever mechanism and a hanging ring, the two ends of the cantilever mechanism are fixed to the two ends of the supporting main beam section to be dismantled, and the two ends of the cantilever mechanism are in lap joint with the non-dismantled supporting main beam sections at the two ends of the supporting main beam section to be dismantled; a plurality of hanging rings are pre-buried on the supporting main beam, and each to-be-dismantled supporting main beam section is provided with a hanging ring. The invention relates to the technical field of foundation pit construction, and can solve the problems that in the prior art, the high-altitude dismantling work amount of a concrete inner support in an ultra-deep foundation pit is large, efficiency is low, and potential safety hazards exist.
本发明公开了一种混凝土内撑免支撑拆除装置及拆除方法，包括用于拆除支撑主梁的支撑主梁拆除组件和用于拆除支撑次梁的支撑次梁拆除组件；支撑次梁拆除组件包括拉结机构和吊环，拉结机构拉结在相邻的待拆除支撑次梁段与未拆除支撑次梁段间，若干个吊环预埋在支撑次梁上，每段待拆除支撑次梁段上设有吊环；支撑主梁拆除组件包括悬挑机构和吊环，悬挑机构的两端固定在待拆除支撑主梁段的两端，悬挑机构的两端搭接在待拆除支撑主梁段两端的未拆除支撑主梁段上；若干个吊环预埋在支撑主梁上，每段待拆除支撑主梁段上均设有吊环。本发明涉及基坑施工技术领域，能解决现有技术中超深基坑内混凝土内撑的高空拆除工程量大、效率低、存在安全隐患的问题。
