[0003] At present, there are similar designs of loading devices for concrete durability tests under compressive stress and multi-factor coupling in China, which mainly use jack loading, wrench screwing nuts and other loading methods. These test devices have the following defects: the jack loading device needs to have The structure and installation process of the reaction frame are relatively complicated, and the operation is inconvenient, and it cannot be put into the carbonization box or other durable equipment; Only sensors and testers can determine the size of the load, which increases the complexity of device measurement

The invention discloses a concrete loading device and method capable of adapting to a load-environment coupling action. The problems in the prior art that the device is complicated in structure and cannot adapt to environment provision equipment are solved. The concrete loading device has the advantages of simplicity in operation and high in test operability. According to the scheme, the concrete loading device comprises a pressing plate for transferring pressure to a concrete test piece, a pressing part used for applying pressure to the pressing plate, and a counter weight mechanism, wherein the pressing part is connected with a lever mechanism; a supporting point of the lever mechanism is fixed with a sleeve device; the counter weight mechanism is arranged on one side or two sides of the pressing plate; the counter weight mechanism is connected with the lever mechanism so as to apply an acting force to the lever mechanism; and the pressure applied to the pressing plate by the pressing part is calculated through the lever mechanism so as to further obtain a load borne by the concrete test piece.
Description
technical field [0001] The invention relates to a concrete test, in particular to a concrete loading device and method which can be adapted to the coupled action of load-environment. Background technique [0002] In actual engineering, most of the damage of concrete is caused by the joint action of load and various environments such as carbonization, penetration, freeze-thaw, corrosion, etc. If only the durability of unloaded concrete specimens is studied, it will not be able to reasonably reflect the condition real environment. Therefore, it is very meaningful to establish a loading device and test method for concrete under the coupled load-environment effect for studying the durability of concrete. [0003] At present, there are similar designs of loading devices for concrete durability tests under compressive stress and multi-factor coupling in China, which mainly use jack loading, wrench screwing nuts and other loading methods. These test devices have the following defe...
