Embodiment Construction

[0082] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0083] In the testing process of the bearing capacity of the cover plate in the prior art, the cover plate will not break and fail immediately after being bent. Since the bottom surface of the pressure beam is flat or curved, when the cover plate is bent, the contact surface between the cover plate and the pressure beam will gradually becomes smaller, and at the same time, a lateral force is generated. This can lead to increased local stresses on the cover plate, which in turn can distort the test results.

[0084] For this, the present invention proposes following scheme:

[0085] Please refer to Figure 1 to Figure 9 , the present invention proposes an active powder concrete cover detection device, including a frame assembly 1, a support assembly 2, a jacking assembly 3 and a pressing ass...

Abstract

The invention discloses an active powder concrete cover plate detection device. A frame assembly is used for providing support for the whole detection device; a supporting assembly is arranged in themiddle of the frame assembly, and a jacking assembly is arranged on the lower portion of the frame assembly and located below a supporting face; a pressing assembly is arranged on the upper portion ofthe frame assembly in a sliding mode, and the pressing assembly is arranged on the frame assembly in a sliding mode and located above the supporting face; the pressing assembly comprises a pressing beam, a shaft body, a first base plate and tension springs; the pressing beam is slidably connected with the frame assembly, and the upper end face of the pressing beam is slidably attached to the upper side wall of a strip hole; a first groove body is formed in the bottom of the pressing beam; a second groove body is formed in the top of the first base plate; the first base plate is connected witha second base plate through a plurality of tension springs; a shaft body is rotationally mounted between the first groove body and a second groove body, and the diameter of the shaft body is larger than the sum of the depth of the first groove body and the depth of the second groove body. According to the invention, the crack resistance and the bearing capacity of the reactive powder concrete cover plate can be detected.

Description

technical field [0001] The invention relates to the technical field of active powder concrete cover plate detection, in particular to an active powder concrete cover plate detection device. Background technique [0002] The cable trough cover and pedestrian walkway are generally made of high-performance concrete rectangular solid slab or reactive powder concrete (RPC type). [0003] Concrete defects are common in high-performance concrete rectangular solid slabs, such as corroded blocks, steel bars corroded, and slabs are prone to breakage. In addition, most of the seriously diseased slabs are replaced, so the number of sidewalk slabs used every year is huge. [0004] Reactive powder concrete (RPC type) is formed by one-time casting of molds. The construction process is perfect, simple, operable, and labor-intensive. The technical proficiency of the operators has little effect on the quality of RPC cover plates, and the quality of the produced products is stable. RPC mater...
