As can be seen from table 2, the connecting piece provided by the embodiment of the application can improve the bearing pressure to 178.23KN after the sleeve is added between the first panel and the second panel.
Specifically, table 3 shows the results of the inspection of the connector stress. In table 3, B represents the connector length, H represents the connector height, B represents the connector thickness, H represents the connector effective height, W represents the moment of resistance, M represents the bending moment, σ represents the connector stress, wherein w= [ BH 3-(B-b)h3 ]/6H, σ = M/W.
In this embodiment, the resisting moment W is calculated according to the connector length B, the connector height H, the connector thickness B and the connector H, and the connector stress σ is calculated according to the resisting moment W and the bending moment M, wherein the connector length B, the connector height H, the connector thickness B and the connector H are examples.
