Description
技术领域technical field
本实用新型属于土木工程构件，具体涉及一种古建木构架摩擦阻尼器装置，主要用于古建筑木结构榫卯节点的加固。The utility model belongs to civil engineering components, in particular to a friction damper device of an ancient wooden frame, which is mainly used for reinforcement of mortise and tenon joints of ancient wooden structures.
背景技术Background technique
古建筑木结构的最大特点是梁柱间榫卯联接，不用一钉一铁而使得结构非常稳定。榫卯节点具有一定的抗弯能力和摩擦耗能能力，然而由于其特殊的联接方式，在历次地震中，木构架易出现节点拔榫、结构闪歪现象，针对榫卯节点的加固，已迫在眉睫。The biggest feature of the wooden structure of ancient buildings is the mortise and tenon joint between beams and columns, which makes the structure very stable without nails and iron. Mortise and tenon joints have certain bending resistance and frictional energy dissipation capacity. However, due to their special connection methods, during previous earthquakes, wooden frames are prone to joint tenon pulling and structural flashing. Reinforcement of tenon and tenon joints is imminent. .
目前，榫卯节点加固中最常见的方法有铁件加固、扁钢加固、CFRP加固和马口铁加固。铁件加固是钢板订于梁下，钢筋插入柱身，利用钢板和钢筋的抗拉能力抵抗外部荷载。扁钢加固是将木梁和木柱用钢板和螺丝联接起来，通过限制梁柱的相对运动实现加固的作用。CFRP加固是将CRFP布包裹于榫卯节点周围，利用碳纤维布的抗拉能力抵抗外部荷载。马口铁加固主要为钢筋直接订入榫卯节点两端的梁柱上。这四种加固办法均增大了结构的自振频率，减小了结构的地震响应，提高了榫卯节点的抗弯能力。但是，破坏了榫卯节点本身的工作机制，同时削弱了结构的抗震能力，甚至使得古建筑在原本残损的基础上破坏更加严重。已有的加固方法或多或少会影响古建筑木结构的性能。At present, the most common methods of mortise and tenon joint reinforcement include iron reinforcement, flat steel reinforcement, CFRP reinforcement and tinplate reinforcement. The reinforcement of iron parts is that the steel plate is fixed under the beam, and the steel bar is inserted into the column body, and the tensile capacity of the steel plate and steel bar is used to resist the external load. Flat steel reinforcement is to connect wooden beams and wooden columns with steel plates and screws, and achieve reinforcement by limiting the relative movement of beams and columns. CFRP reinforcement is to wrap CRFP cloth around the mortise and tenon joints, and use the tensile capacity of carbon fiber cloth to resist external loads. The reinforcement of tinplate is mainly that the steel bars are directly fixed on the beams and columns at both ends of the mortise and tenon joints. These four reinforcement methods all increase the natural vibration frequency of the structure, reduce the seismic response of the structure, and improve the bending resistance of the mortise and tenon joints. However, the working mechanism of the mortise and tenon joint itself is destroyed, and at the same time, the earthquake resistance of the structure is weakened, and the damage of the ancient building is even more serious on the basis of the original damage. Existing reinforcement methods will more or less affect the performance of ancient wooden structures.
考虑到减震技术在现代建筑中已得到了应用，如阻尼器可以给结构提供附加阻尼，起到减震作用。地震中，阻尼器在结构进入塑性耗能状态前率先进入耗能状态，发挥其耗能作用，减小了结构本身地震响应，进而有效的保护了主体结构。但是，阻尼器加固在古建筑木结构中鲜有应用。Considering that shock absorption technology has been applied in modern buildings, for example, dampers can provide additional damping to the structure and play a role in shock absorption. During an earthquake, the damper first enters the energy-dissipating state before the structure enters the plastic energy-dissipating state, exerts its energy-dissipating effect, reduces the seismic response of the structure itself, and effectively protects the main structure. However, damper reinforcement is rarely used in ancient wooden structures.
