In addition, through the setting of the middle limit plate, the two force transmission buffer plates can ensure the accuracy of position positioning, and the installation is convenient and simple, and the subsequent maintenance and repair are also more convenient.

[0082] Example 4

[0083] The above-mentioned embedded single-cavity panel positioning device for assembled pavement realizes the buffer positioning connection between two adjacent prefabricated road panels by setting two embedded positioning mechanisms and a force transmission limit mechanism connected between the two embedded positioning mechanisms. When the two adjacent prefabricated road panels are subjected to force, the first force transmission buffer plate and the second force transmission buffer plate realize the force transmission between the two adjacent prefabricated road panels.

[0086] When multiple pre-embedded positioning mechanisms are subjected to force at the same time, due to the different positions of the force transmission buffer plates in different pre-embedded positioning mechanisms, after the pre-embedded positioning mechanisms are subjected to force transmission from the prefabricated road panel, the force transmission buffer plates at different positions are not uniformly transmitted, thus achieving continuous force unloading at different stages of the pre-embedded positioning mechanisms. Under the condition of ensuring the rigidity of the structural limit, the buffering effect of force unloading is improved, rigid force unloading is avoided, and thus rigid damage to the prefabricated road panel is avoided. In addition, through the setting of the middle limit plate, the two force transmission buffer plates can ensure the accuracy of position positioning, and the installation is convenient and simple, and the subsequent maintenance and repair are also more convenient.
