Nondestructive demounting method for prefabricated part of IMS system Dai nationality folk house major structure

Abstract

The invention discloses a method for demounting a prefabricated part without damage in an IMS system Dai nationality dwelling major structure, which selects and marks key points on the IMS system Dai nationality dwelling major structure, and carries out controllable slow release to the prestress of a steel stranded wire in each key point, without impact and damage on the prefabricated part in theprestress release process. After a prefabricated beam and a prefabricated slab of a floor are demounted and hanged back to the ground, open-channel post-cast concrete and the steel stranded wire contained in the concrete are separated out from the prefabricated beam and the prefabricated slab for leading the prefabricated beam and the prefabricated slab to be restored. The method can realize the undamaged recovery and reuse of the prefabricated beam, the prefabricated slab and a prefabricated column when demounting the IMS system Dai nationality dwelling, and is economical and environmentallyfriendly, thus being suitable to demounting not only the IMS system Dai nationality dwelling but also other IMS system buildings, and having reference function for demounting non-IMS system prestressstructures.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a non-destructive dismantling method for the prefabricated components of the main structure of Dai folk houses. Background technique [0002] According to statistics, 40% of my country's current urban new building area is achieved by demolishing old buildings, and it is also common for rural houses to be rebuilt every few years. The durability survey found that concrete components in environments with an actual service life of 70 to 80 years are basically intact. Therefore, under the premise of standardization, prefabricated concrete components dismantled before reaching this age can be used in other buildings after processing. continue to use. [0003] The traditional dwellings of the Dai people use wood as the main building material. When the buildings are relocated and demolished, no hard-to-degradable construction waste will be produced. The old wood can sti...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiency that the prefabricated components cannot be reused due to the damage caused by the demolition of the main structure of the IMS Dai folk houses by blasting, and provide a non-destructive disassembly method for the prefabricated components of the main structure of the IMS system Dai folk houses. At the key points of the structure, the prestress of the steel strands at the key points is controlled and slowly released, so that the prefabricated components of the main structure of the IMS system can be dismantled without damage
