Method for rapidly repairing wood structure crack of ancient building
The invention discloses a rapid repairing method for historic building wood structure cracks, which comprises the following steps: preparing a polyurethane reactant, pouring the cracks, foaming polyurethane, opening a mold for the cracks, waiting for 2-3 days, and removing iron wires and iron sheets on the wood cracks, thereby completing the repairing. According to the method, the wood crack serves as a mold, the polyurethane foaming principle is utilized, the hard polyurethane material generated in the wood crack is tightly combined with the crack, the shape of the hard polyurethane material is highly matched with that of the crack, and a tightly-connected common stress body can be formed. The hard polyurethane has the wood characteristics of light weight and high strength, the porous characteristic, the density and the specific gravity of the hard polyurethane are highly similar to those of wood, meanwhile, the air permeability of an air hole structure of the hard polyurethane is convenient to adjust, and other secondary damage can be effectively avoided. The strength, modulus, cohesiveness and other material mechanical properties of the hard polyurethane material have good adjustability, it can be guaranteed that the material has good material mechanical properties during repairing, the material can be tightly combined with wood, synergistic stress and deformation are achieved, and the mechanical properties and weather resistance of components are recovered or improved.
本发明公开了一种古建筑木构裂缝快速修复方法，包括：配制聚氨酯反应物、裂缝浇筑、聚氨酯发泡、裂缝开模，等待2‑3天后，去除木材裂缝额铁丝和铁片，即完成修复。本发明以木材裂缝为模具，利用聚氨酯发泡原理，在木材裂缝中生成的硬质聚氨酯材料与裂缝结合紧密，形状高度契合，可形成紧密连接的共同受力体。硬质聚氨酯具有轻质高强的材性特点，其多孔特性和密度、比重都与木材高度相近，同时其气孔结构的透气性便于调节，可有效的避免其他次生损害。硬质聚氨酯材料强度、模量、粘结性等材料力学性能具有较好的可调控性，可保证修复时材料具有良好的材料力学性能，与木材结合紧密，协同受力与变形，恢复或提升构件力学性能和耐候性能。
