Integral hoisting method for ancient building caisson

Abstract

The invention relates to an integral hoisting method for an ancient building caisson, and belongs to the technical field of ancient building restoration. The integral hoisting method includes the following specific steps that firstly, caisson protection is carried out, an elastic protection layer is laid on the surface of the caisson, and the integrity of the caisson is strengthened by a strengthening structure; secondly, dimension measurement is carried out; thirdly, a support is erected; fourthly, a lifting tool is installed; fifthly, integral elevation is carried out, the caisson is liftedslowly by a hoisting mechanism, and a multiple-section lifting mode is adopted when the caisson is lifted; and sixthly, caisson descending is carried out, the caisson is lowered slowly by the hoistingmechanism, and a subsection descending mode is adopted when the caisson falls. When a beam frame of an ancient building with the caisson is restored, the caisson of the ancient building can be hoisted integrally, there is no need to dismantle the caisson, and the integrity of the caisson is not easily 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 ...

AI Technical Summary

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
