A prefabricated concrete pavement panel connection structure and construction method
PendingCN122082315Aavoid misalignmentprevent looseningSingle unit pavingsClimate change adaptationIsosceles trapezoidRoad engineering
This invention discloses a prefabricated concrete pavement panel connection structure and construction method. With the development of prefabricated building technology, the application of prefabricated concrete pavement panels in road engineering is becoming increasingly widespread. In this invention, the upper and lower dovetail interlocking steel plates are identical in shape, forming a dovetail shape composed of two symmetrically arranged isosceles trapezoids. After the prefabricated concrete pavement panels one and two are spliced, an upper interlocking groove is formed on the top surface, and a lower interlocking groove is formed on the bottom surface. The upper interlocking steel plate is embedded in the upper interlocking groove; the lower dovetail interlocking steel plate is embedded in the lower dovetail interlocking groove; the upper and lower dovetail interlocking steel plates, and the prefabricated concrete pavement panels one and two are connected by steel plate fasteners; the sides of the prefabricated concrete pavement panels one and two are provided with tongue and groove joints; the tongue and groove joints on the concrete pavement panels one and two are spliced to form grouting grooves; grouting holes are provided on the upper and lower interlocking steel plates. This invention achieves efficient transfer of horizontal and vertical loads on the pavement panels, improves the overall integrity and durability of the structure, and has high construction efficiency.
