Description
Technical Field
The invention belongs to the technical field of building structure engineering, and relates to a resetting device and a resetting method for supporting and monitoring the offset of a column body.
Background
The traditional Chinese buildings are integrated in the world building history, and are planted in the Chinese earth and radiate to affect the surrounding countries and regions. The traditional wood structure building has the special structure and shape, so that the wood structure building has the characteristic of preventing collapse of a wall and a house, and is beneficial to the special structure, and the wood structure ancient building continues in the Chinese field for thousands of years, so far, a plurality of ancient buildings in civilization and foreign countries are left. Meanwhile, the archaized buildings built according to the traditional standard are also widely popularized and are widely applied to various places. One of the most basic features of traditional Chinese timber structure building is its unique structural form, which comprises three major components, namely, a foundation, a timber frame and a roof. The timber frame is a core bearing structure, is a skeleton of the whole building, generally consists of members such as a column, a beam, a purlin, a rafter, a bucket and the like, and plays a role in stabilizing the whole building and bearing the weight of a roof. The 'fat beam, fat column and weak node' are one of the remarkable characteristics of the wooden frame, the strength of a single member has higher redundancy, and the connection between the members is weaker and is the weakest link in the wooden frame system.
The wood column is one of the most central stressed members in various wood members of a wood frame system. Most of the wood columns are erected on the foundation stones in a floating mode, and no effective mechanical connection exists between the wood columns and the foundation stones. The foundation stone is large in mass and low in gravity center, so that the foundation stone basically does not have position change under the action of an earthquake; the wood column has light weight and high gravity center, and can generate motions such as swinging, sliding and the like when an earthquake occurs, and the bottom surface of the wood column generates relative displacement with the top surface of the foundation stone. The relative motion of the foundation stone-wood column interface within a certain range is the dissipation and release of input seismic energy, which is beneficial to the earthquake resistance of the structure, but once the relative displacement exceeds the top surface of the foundation stone, the wood column is easy to topple, and the collapse of the whole building is induced. To prevent the wooden pillars from slipping out of the range of the base stones, the top surface of the base stones is often larger than the cross-section of the pillars. In order to avoid secondary accidents caused by deviation of the wooden columns, the wooden columns which have been displaced need to be restored to the centers of the foundation stones by adopting a resetting means in time. Furthermore, the behaviour of the wooden pole is decisive for the safety status of the whole structure. Health monitoring and behavioral survey to the post need rely on all kinds of sensing equipment, and the sensor is located the post facade more, not only influences pleasing to the eye, and the installation of sensor, fixed still inevitably causes local damage to the post.
The existing wood column resetting and correcting means usually needs other jacking equipment or even large machinery, and the process is complicated and complex to operate. Some of the disclosed devices have the effects of wood column earthquake resistance or foundation stone vibration isolation, but the existing problems are that the functions of the devices are single on one hand, and the due earthquake resistance mechanism of the traditional wood structure building is mostly destroyed on the other hand.
