AI Technical Summary

Technical Problem

During the construction of asphalt pavement, gaps can easily form between the newly laid pavement and the already cured pavement before the newly laid pavement is fully cured, leading to collapse.

Method used

The system employs a primary and secondary support plate structure. A drive mechanism drives a clamping component to tighten the secondary support plate, ensuring it adheres to the side of the paved road surface. During the curing process, the plate is attached to the road surface. The device is removed when laying the next section of the road, forming a vertical support and preventing gaps from forming.

Benefits of technology

It effectively prevents road surface collapse due to gaps during the curing process, ensures the integrity and smoothness of the road surface connection, and improves the quality of asphalt pavement joints.

Abstract

This utility model relates to the field of road joint technology, specifically to an asphalt pavement joint structure, including a primary support plate, two secondary support plates, and a fixing seat. The primary support plate abuts against the side of the paved road surface. The secondary support plates are located on the side of the primary support plate away from the paved road surface, and the fixing seat is located on the side of the secondary support plate away from the primary support plate. A driving structure is provided in the middle of the fixing seat, and a tightening member is provided at the end of the driving structure. Two fixing mechanisms are also provided at both ends of the fixing seat, and two guide mechanisms are symmetrically provided at the lower part of the fixing seat. This utility model indirectly tightens the primary support plate against the side of the paved road surface by driving the tightening member through the driving structure, fixing the road surface during the current road surface curing process and preventing the road surface from collapsing outward. At the same time, the other devices except for the primary support plate can be removed when paving the next road surface. The primary support plate can provide support for the corresponding side of the next road surface segment, preventing the formation of collapse gaps between the two road surface segments due to curing.
