Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the examples.
[0028] refer to Figure 1 to Figure 4 , an expandable column diameter device with a replaceable built-in pre-tightened steel hoop, comprising setting a steel hoop 2 and a steel hoop 3 at the foot of a wooden column 1 of an ancient building, the steel hoop 2 and the steel hoop 3 are connected by bolts, and the steel hoop 3 is connected by bolts. The outer side of the hoop 2 and the steel hoop 3 is provided with a reinforcement member 4 and a reinforcement member 5. The reinforcement member 4 and the reinforcement member 5 are two annular cylinders with semicircular cross-sections, and annular grooves are opened on the inner walls of the reinforcement member 4 and the reinforcement member 5 respectively. 6 and the annular groove 7, the groove is used to fasten the steel hoop pre-tightened on the wooden post 1.

Abstract
The invention discloses a column diameter expanding device capable of replacing built-in pre-tightening steel hoops and a mounting and dismounting process thereof.The column diameter expanding device is characterized in that steel hoops are arranged at column feet of historic building wooden columns, the steel hoops are connected through bolts, reinforcing parts are arranged on the outer sides of the steel hoops, the reinforcing parts are two annular columns with semicircular sections, and the steel hoops are connected through bolts; annular grooves are formed in the reinforcing pieces and the inner walls of the reinforcing pieces respectively, and the grooves are used for buckling steel hoops pre-tightened on the wooden column. The stress performance of the wooden column is improved by enlarging the diameter of the column foot of the ancient building wooden column. The larger the column diameter is, the larger the resistance bending moment provided by the wooden column in the swinging process is, and the higher the self-resetting capacity is.
Description
technical field [0001] The invention belongs to the technical field of ancient building reinforcement, and particularly relates to a column diameter expansion device capable of replacing a built-in pre-tightening steel hoop, and an installation and disassembly process thereof. Background technique [0002] In the large wooden structure of ancient Chinese buildings, wooden columns are important load-bearing components, which can be described as "standing wooden tops". Wooden columns bear the weight of the superstructure of ancient buildings. Ancient buildings provide excellent seismic performance, therefore, it can be said that wooden columns are the earthquake-resistant core of wooden structures of ancient buildings. However, due to the limitations of ancient technology, the material of wooden pillars usually uses logs mined in nature, which cannot effectively avoid adverse factors such as wood knots, dry cracks and decay caused by growth defects, and the mechanical performa...
