技术领域technical field
本发明属于古建筑加固技术领域,特别涉及一种组合橡胶垫增强减震的柱径扩大装置及安装工艺。The invention belongs to the technical field of ancient building reinforcement, and particularly relates to a column diameter expansion device and an installation process for enhancing shock absorption by combining rubber pads.
背景技术Background technique
古建筑木结构以其独特的结构形式抵御外部荷载的破坏,其中木柱承接建筑上部结构与地基,是古建筑抗震的重点研究对象。木柱由于其榫卯的特点,依靠摇摆与滑动摩擦耗散地震能量,有效保障整体建筑的安全可靠。因此,从力学角度来看,木柱的直径大小直接影响着建筑的抗震能力,木材的材料特性也限制着木结构建筑的耗能能力。The wooden structure of ancient buildings resists the damage of external loads with its unique structural form. The wooden columns undertake the superstructure and foundation of the building, and are the key research objects of earthquake resistance of ancient buildings. Due to its mortise and tenon feature, the wooden column relies on swing and sliding friction to dissipate seismic energy, effectively ensuring the safety and reliability of the overall building. Therefore, from a mechanical point of view, the diameter of the wooden column directly affects the earthquake resistance of the building, and the material properties of wood also limit the energy dissipation capacity of the wooden structure.
现有的木柱加固方式很少从结构角度出发增强木柱的抗震性能,类似开槽植筋等提高木柱承载能力的加固方式对古建筑原有木柱会造成破坏,不满足最小干预的修缮加固原则。The existing wooden column reinforcement methods rarely enhance the seismic performance of the wooden column from the structural point of view. The reinforcement methods that improve the bearing capacity of the wooden column, such as slotted planting, will cause damage to the original wooden column of the ancient building, which does not meet the requirements of minimal intervention. The principle of repair and reinforcement.

本加固方法具有可更换特点,由于加固件与木柱之间不依靠其他固定措施,仅靠预紧力,所以加固装置很容易拆换,可根据实际需要选取不同柱径与高度的加固件。同时,仅靠预紧力连接最大程度减少了对原有古建筑的干预,符合古建筑修缮加固原则。The reinforcement method has the characteristics of being replaceable. Since the reinforcement and the wooden column do not rely on other fixing measures, but only rely on the pre-tightening force, the reinforcement device is easy to disassemble and replace, and reinforcements with different column diameters and heights can be selected according to actual needs. At the same time, only relying on pre-tightening connection minimizes the intervention on the original ancient buildings, which conforms to the principles of repair and reinforcement of ancient buildings.
本加固方法使用高弹橡胶来提高木柱的耗能能力,在一定程度上减轻了由于摇摆挤压对木柱造成的损伤。The reinforcement method uses high-elasticity rubber to improve the energy dissipation capacity of the wooden column, thereby reducing the damage to the wooden column caused by the swing extrusion to a certain extent.
