Concrete column reinforcement structure and construction method thereof
The invention discloses a concrete column reinforcement structure and a construction method thereof. The concrete column reinforcement structure comprises a UHPC substrate layer, a porous steel plate,a UHPC bonding layer, a fiber woven net and a UHPC protective layer which sequentially coats the side wall of a to-be-reinforced concrete column from inside to outside, wherein the porous steel plateis provided with through holes; and the UHPC bonding layer is bonded with the UHPC substrate layer through the through holes of the porous steel plate. Through the adoption of the UHPC substrate layer, the higher compatibility between a reinforcement layer and an original concrete structure can be achieved, as well as the aging-resistant, high-temperature-resistant and moisture-resistant properties can be good; through the fiber net connection mode, the fiber material interconnection effect of a fiber composite material can be sufficiently exerted, and the fiber material utilization ratio canbe improved; the UHPC substrate and the UHPC bonding layer are tightly bonded through the through holes of the porous steel plate, so that not only can the internal and external UHPC bonding capability be enhanced, but also the corrosion-resistant property and the fire-resistant property can be improved; and all the components of the concrete column reinforcement structure can be combined to forma whole subjected to common stress and deformation, and the mechanical properties of the to-be-reinforced concrete column can be improved.
本发明公开了一种混凝土柱加固结构及其施工方法，包括由内至外依次包覆在待加固混凝土柱侧壁上的UHPC基体层、布设有通孔的密孔钢板、UHPC粘结层、纤维编织网和UHPC保护层，UHPC粘结层通过密孔钢板的通孔与UHPC基体层粘结。本发明采用UHPC基体层可使加固层与原混凝土结构间有更好的相容性，抗老化、耐高温、耐潮湿性能好。纤维复合材料通过纤维网的连接方式充分发挥纤维材料相互连接作用，提高纤维材料的利用率。UHPC基体层与粘结层通过密孔钢板上的通孔紧密粘结，不仅增强内外UHPC的粘结能力，而且能提高抗腐蚀性能和耐火性能。本发明各组成部分形成一个共同受力和变形的整体，提升待加固混凝土柱的力学性能。
