Concrete column circumferential reinforcing structure and reinforcing method
The invention relates to the technical field of civil engineering reinforcement, in particular to a concrete column circumferential reinforcing structure and a reinforcing method.The concrete column circumferential reinforcing structure comprises a main body mechanism which comprises a concrete column and a wrapping component installed on the outer side of the concrete column in a matched mode; the wrapping part comprises a shape memory alloy plate arranged on the outer side of the concrete column, a cushion block arranged on the outer side of the shape memory alloy plate and an anchorage device installed in the shape memory alloy plate and the cushion block in a matched mode. The shape memory alloy plate is used for wrapping and reinforcing the cracked area or the area with the cracking risk of the concrete column, the stress amplitude of the cracked portion of the structure can be reduced, then crack initiation and expansion are restrained, complex construction equipment is not needed, high adaptability is achieved under the condition that the construction space is limited, and the construction cost is reduced. In addition, according to the method, the structure is reinforced, and meanwhile, the original structure cannot be damaged.
本发明涉及土木工程加固的技术领域，尤其涉及一种混凝土柱环向加固构造及加固方法，包括主体机构，其包括混凝土柱，以及适配安装在所述混凝土柱外侧的包绕部件，所述包绕部件包括设置在所述混凝土柱外侧的形状记忆合金板、设置在所述形状记忆合金板外侧的垫块，以及适配安装在所述形状记忆合金板和所述垫块内部的锚具；利用形状记忆合金板对混凝土柱已开裂或具有开裂风险的区域进行包裹加固，能够降低结构开裂部位的应力幅，进而抑制裂缝的萌生与扩展，无需复杂施工设备，对于施工空间受限的情况有较强的适应性，且对各种形状的混凝土柱具有良好的适配性，另外，本发明在加固结构的同时，不会对原有结构造成损伤。
