An integral hoisting method for caissons in ancient buildings

Abstract

The invention relates to an integral hoisting method for an ancient building algae well, which belongs to the technical field of ancient building restoration. The specific steps are as follows: the first step, algae well protection: an elastic protective layer is laid on the surface of the algae well, and the integrity of the algae well is protected by the reinforcement structure. Reinforcement; the second step, dimension measurement; the third step, setting up the bracket; the fourth step, the installation of the spreader; the fifth step, the overall lifting: slowly lift the caisson through the lifting mechanism, and adopt a multi-stage lifting method when lifting the caisson; Step 6: Restoration of the algae well: Slowly lower the algae well through the lifting mechanism, and adopt the method of segmental descent when the algae well is lowered. The invention can lift the caisson of the ancient building as a whole when repairing the beam frame of the ancient building with the caisson, so that the caisson does not need to be dismantled, so that the integrity of the caisson is not easy to be damaged.

Description

technical field [0001] The invention relates to the technical field of ancient building restoration, in particular to an integral hoisting method for an ancient building caisson. Background technique [0002] my country's ancient architecture has a long history, and its unique construction style and structure also occupy a very important position in the history of world construction, and its scientific value and artistry are even more immeasurable. Ancient buildings are also left over from long-term historical development, and cannot be regenerated or rebuilt. If they are damaged, they cannot be recovered. In the historical development, due to the influence of natural or human factors, ancient buildings have been damaged or even destroyed. Therefore, effective restoration and protection measures must be taken to make the cultural heritage of ancient buildings appear for a long time. [0003] Most of the ancient buildings, palaces, temples, etc. will have algae wells on the ...

Problems solved by technology

[0004] It is not too difficult to repair the fallen beams of ancient buildings. It is necessary to dismantle the seven beams, five beams, three beams and other beams of the building, as well as the purlins in the open room and the secondary room. However, due to the The existence of caissons has increased the difficulty of construction for this project, because the load-bearing structure of the caissons is mostly built on the seven beams of the building through stepped tenons. Disassembly, if the bearing structure of the algae well is dismantled, it will inevitably disturb the algae well

Since the caisson body of a traditional Chinese caisson is not an integral component, but is assembled by a dozen single components and dozens of dougongs in turn, if the caisson is dismantled and installed during construction, it is not easy to ensure that the caisson The integrity of the algae well, and the color painting and carving of the algae well are easy to be damaged during the dismantling process. If the integrity of the algae well is damaged during the dismantling process, it will not be reversed
