Embodiment Construction

[0024] The specific design and construction procedures for the octagonal wooden tower are as follows:

[0025] (1) Tower body detection and component reinforcement design: measure the torsional deformation value and vertical offset value of the floor, measure the misalignment and deformation value of each component; detect the damaged part and damage degree of the component, and plan the repair and reinforcement of the damaged component Requirements (for seriously damaged components, it is advisable to reinforce or replace them before tension reset to ensure safety during construction); determine the nodes and parts of the floor that are fastened and supported by wooden wedges during tension reset.

[0026] (2) Loading scheme design: formulate the target recovery value of the tension reset of the floor, calculate the total tension and deformation control value, and determine the number and arrangement of tensioners according to the design scheme of multi-layer simultaneous cons...

Abstract

The invention discloses a restoring method of wood structural pavilion-like tower, which is characterized by the following: forcing the bulking tower with the inversed reset couple of buckling deforming direction; setting the typical reinforcer in the tower after the tower restores to the preset position; removing the couple. The invention is easy to deposit and adjust, which adapts construction rack as loaded working platform to save the cost of special loaded structure and assembly time limit for a project.

Description

technical field [0001] The invention relates to a technical method for repairing wooden structure pavilion-type towers. Background technique [0002] Under the long-term wind load, especially when subjected to earthquakes, the wooden tower structure is prone to deformation. The main characteristics of this deformation are twisting deformation in the plane and vertical oblique deformation. Once the tower structure is twisted and tilted, the wooden structure will be disengaged on the tension side, split or deflected on the compression side, and the bucket arch will be loosened. With the long-term effect of environmental load and material aging, the strength of components decreases and the stiffness degrades, resulting in the gradual increase of distortion and inclination of the structure. The famous Shakya Pagoda in Ying County in my country is a typical pavilion-style wooden pagoda. After more than 900 years of vicissitudes, it tilts to the north and east as a whole. The sec...
