During the construction process, many components need to be cast-in-place. The cast-in-place components must be supported by formwork. Now the general formwork is a wood formwork or a steel formwork. The cost of making the formwork requires a certain cost, and it needs to be installed continuously during the application process. The template is removed and the workload is large. Moreover, at present, wood resources are becoming less and less, and building energy consumption accounts for more than half of the total energy consumption.

本发明实施例还提供一种自带阴极防护功能的钢筋混凝土结构,即带阴极防护功能的新型纤维复合材料多功能免拆模板-钢筋-混凝土组合结构,如图2所示,所述自带阴极防护功 能的钢筋混凝土结构包括:免拆模板1组成的模板结构,浇筑在模板结构内的混凝土2,埋置在混凝土2内的多根钢筋3,及用于对钢筋3施加恒定大小的电流的外部电源4。其中,所述多根钢筋3之间电性连接;所述钢筋3、混凝土2、免拆模板1、外部电源4依次电性连接。The embodiment of the invention further provides a reinforced concrete structure with a cathodic protection function, that is, a novel fiber composite multi-functional free-removal template-reinforcing-concrete composite structure with a cathodic protection function, as shown in FIG. 2, the self-contained The reinforced concrete structure with cathodic protection function includes: a formwork structure composed of a free formwork 1, a concrete 2 poured in the formwork structure, a plurality of steel bars 3 embedded in the concrete 2, and a constant current applied to the steel bars 3 External power supply 4. The plurality of steel bars 3 are electrically connected to each other; the steel bars 3, the concrete 2, the detachable template 1, and the external power source 4 are electrically connected in sequence.
为了达到阴极防护的目的,本发明钢筋3-混凝土2-免拆模板1结构体系应形成完整的电通路而能顺利地传递阴极保护电流。因此,本发明实施例中,所述外部电源4连接于钢筋3和免拆模板1内的纤维材料层之间,使钢筋3、外部电源4、纤维材料层形成回路,构成阴极防护系统。其中,由CFRP材料构成的纤维材料层为阴极防护系统的阳极,钢筋为阴极防护系统的阴极。所述的纤维复合材料多功能免拆模板,在本发明自带阴极防护功能的钢筋混凝土结构中,起到了组合结构材料和辅助阳极的作用,其在长期荷载、环境因素和保护电流共同作用下,具有可靠的力学性能、电化学特性和耐久性等,能支撑新型结构体系同时发挥结构性能增强和阴极防护的功能。In order to achieve the purpose of cathodic protection, the steel-concrete 2-concrete 2-disassembly template 1 structure system of the present invention should form a complete electrical path and smoothly transfer the cathodic protection current.

The system adds a cathodic protection system to the foundation of the traditional combined structure, which not only follows the advantages of the combined structure, but also obtains the cathodic protection of the structure.
优选的,还可以在图2所示的自带阴极防护功能的钢筋混凝土结构中增加控制装置和检测装置,所述控制装置串联在以上形成的回路中,用于对回路中的电流大小进行控制;而所述检测装置连接在钢筋和混凝土之间,用于对钢筋的腐蚀状况进行检测。Preferably, the control device and the detecting device can also be added to the reinforced concrete structure with the cathodic protection function shown in FIG. 2, and the control device is connected in series in the loop formed above for controlling the current in the loop. And the detecting device is connected between the steel bar and the concrete for detecting the corrosion condition of the steel bar.
