Integral synchronous lifting method for wood structure of ancient building

Abstract

The invention provides an integral synchronous lifting method for a wood structure of an ancient building. The integral synchronous lifting method for the wood structure of the ancient building comprises the following steps: numbering and detaching non-bearing members at first; erecting an all-round scaffold assisting to construction and equipment installation according to a shaft screen; and fully laying steel plates below the scaffold. A cross bridging is arranged between a beam and a column of the ancient building, angle steel is fixed to the junction of the beam and the column, and a plinth through split bolts to carry out reinforcement for a mortise-tenon joint, and the cross bridging, the angle steel at end parts, and connection elements are fixed through measures. Intelligent electric hoists are installed on a high-layer cross rod of the scaffold, and a matching flexible steel suspension cable is installed on each intelligent electric hoist. A steel beam is bound among depths separately, and firm binding is carried out on each flexible steel suspension cable and the steel beam. A wireless displacement sensor is placed at the angle steel at the plinth, and a wireless strain sensor is placed in the vicinity of the mortise-tenon joint. Data detected by the sensor and the strain sensor is transmitted into an integrated console, and hoisting speeds of the electric hoists arecontrolled to realize and complete integral lifting for the structure. According to the integral synchronous lifting method for the wood structure of the ancient building, digital and informational judgement is adopted in a construction process, so that higher safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the construction technical field of ancient building protection; in particular, it relates to an overall synchronous lifting method for an ancient building wooden structure. Background technique [0002] At present, in China's existing architectural heritage, wooden architectural heritage accounts for the majority, and its shape, structure, material, structure, and craftsmanship are of great significance to the study of the wisdom of ancient ancestors and the scientific mechanism of China's excellent traditional architecture. Therefore, the scientific and reasonable protection of these precious ancient wooden structures must be the top priority. After a long period of time, the wooden structure of ancient buildings will inevitably produce material damage accumulation. Once there is a strong external force, these architectural heritages will be at risk of damage. In addition, due to the change of historical dynasties, the groun...

Problems solved by technology

After a long period of time, the wooden structure of ancient buildings will inevitably produce material damage accumulation. Once there is a strong external force, these architectural heritages are at risk of damage

In addition, due to the change of historical dynasties, the ground of urban roads has been continuously filled up, causing the indoor ground of most ancient wooden structures to be significantly lower than the outdoor ground, which will cause rainwater to pour back and waterlogging, and easily cause decay and collapse of ancient wooden structures Therefore, when repairing and protecting these important architectural heritages, more reasonable repairing and construction techniques are needed to protect their overall safety.

[0003] In recent years, the overall building lifting technology has developed to a certain extent, but due to the special joint structure of the wooden structure, the semi-rigidity of the mortise and tenon joints makes the existing lifting technology easy to cause local damage to the wooden structure, or due to acceleration during the lifting process. Too fast, resulting in the accumulation of damage to the mortise and tenon joints, which makes the ancient buildings have safety hazards in the subsequent service

In addition, because the current lifting technology relies too much on human subjective control, uneven lifting is prone to occur, and it is easy to cause excessive deformation and damage the structure during the lifting construction process.

To sum up, the current methods of overall upgrading of ancient wooden structures still need to be further studied.
