Method for repairing cracks in wooden structures by using fiber reinforced concrete
The invention discloses a method for repairing cracks in wooden structures by using fiber reinforced concrete. The method includes the following steps that (1) the cracks in the wood structures are marked; (2) a plurality of X-shaped or dumbbell-shaped grooves are ground along the cracks; (3) wood chips and loose parts in the grooves are removed; (4) the fiber reinforced concrete is poured in thegrooves; (5) curing and hardening are carried out; and (6) surface treatment is carried out. According to the method, the advantage of low cost, high tensile strength and easy forming characteristicsof the fiber reinforced concrete are used, the fiber reinforced concrete is used to replace the wood structures to bear the stress state at original crack positions, the defect of low tensile strengthof the wood structures is compensated, and the emergence and development of the cracks can be effectively controlled. The problem that an existing wood structure crack repairing method can cause irreversibly change on the original appearance of a body is solved, the integrity of the original appearance of the wood structures is guaranteed, the improvement of the overall mechanical performance isrealized by making the repaired wood structure into a whole, and the method has the advantages of capable of enabling the deformability of the repaired wood structures to be improved, the service lifeof the repaired wood structures to be prolonged, and the maintenance frequency of the repaired wood structures to be reduced.
一种利用纤维混凝土修复木结构裂缝的方法，包括以下步骤：1)木结构本体裂缝标记；2)沿裂缝磨出数个X型或哑铃型凹槽；3)清除凹槽内木屑及松散部分；4)在凹槽内浇筑纤维混凝土；5)养护硬化；6)表面处理。本发明利用纤维混凝土的低成本、高抗拉强度和容易成型的特点，代替木结构以承受其在原有裂缝位置的受力状态，弥补了木结构抗拉强度低的缺陷，同时可有效控制裂缝的产生与发展。本发明解决了现有木结构裂缝修复方法会对本体原貌产生不可逆改变的问题，保证木结构原貌的完整性，并通过使修复后木结构成为整体，实现整体力学性能的提升，具有能让修复后木结构变形能力提高、使用寿命延长、维修频率降低的优点。
