Technical Field

[0001] The utility model relates to the technical field of concrete aging test after repair, in particular to concrete aging test equipment after mortar repair. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in power transmission and transformation projects.

[0003] After a period of use, concrete will age, such as cracking and peeling. Therefore, in order to improve the stability of concrete, it is necessary to repair it, usually with mortar repair. However, the repaired concrete blocks need to be subjected to aging tests. For example, the Chinese invention patent application with publication number CN114858693A discloses an asphalt concrete aging test device under the coupling of multiple factors, which provides a test device with a simple structure, flexible disassembly, convenient operation, and fast and efficient for the durability test of asphalt concrete in indoor simulated complex environments. It includes a refrigeration system, a test chamber, a spraying device and a control device. The device can realize the test of asphalt aging under the coupling of multiple factors such as ultraviolet intensity, freeze-thaw, humidity, oxygen and harmful substances, so as to simulate the aging of asphalt concrete in a natural environment more realistically and accurately, and provide basic equipment for systematically and comprehensively carrying out multi-factor durability research on asphalt concrete in a natural environment.

[0004] The technical solution described in the above patent can simulate coupling of various natural environments to conduct aging tests on repaired concrete blocks, but it still has the following shortcomings in actual use:

[0005] Concrete blocks are heavy, and current test chambers usually have sealed doors on the sides of the chamber, which requires the concrete side to be moved to the inside of the chamber, making operation inconvenient. Moreover, the natural environment simulated by current experimental equipment still has defects. Utility Model Content

[0036] Specifically, the bottom of the L-shaped frame 4 is fixedly connected to the linear guide rail 3, and the lower box body 1 is slidably set on the linear guide rail 3 through a slider 301, so that the lower box body 1 can slide on the linear guide rail 3, thereby allowing the lower box body 1 to quickly switch between the test station and the idle station.

[0037] The environmental simulation component is arranged inside the upper box body 2; specifically, the environmental simulation component includes a cold air circulation pipe 13, a shower pipe 14, an ultraviolet lamp 15 and a heating lamp 16.
