AI Technical Summary

Technical Problem

During the construction of the airport road surface, the installation and positioning of the force transmission rod is not accurate, the hole position leaks, and the mold removal is difficult, and the longitudinal template and the force transmission rod are not universally applicable, which increases the equipment cost.

Method used

The force transmission rod installation structure includes a longitudinal template, a sub-hole support and a clamping member is adopted. Through the gap fit of the sub-hole support and the clamping mechanism of the clamping member, the precise positioning and stable installation of the force transmission rod are ensured, and the gap between the force transmission rod and the support ring is sealed through a sealing ring to avoid slurry leakage.

Benefits of technology

The precise positioning and stable installation of the force transmission rod is achieved, which reduces the problem of slurry leakage, simplifies the mold removal process, reduces the cost of equipment, and adapts the longitudinal template to the force transmission rod of different specifications.

Abstract

The invention discloses a dowel bar mounting structure for airport pavement pouring connection and a construction method thereof, and relates to the airport pavement construction equipment technology, the dowel bar mounting structure comprises a longitudinal formwork, sub-hole supporting pieces are mounted in mounting holes of the longitudinal formwork, each sub-hole supporting piece comprises a cylindrical part and a connecting part, and the annular end face, away from the connecting part, of each cylindrical part is provided with a supporting ring; the cylindrical part is in clearance fit with the mounting hole piece, and a clamping piece is mounted in a first dowel bar inserting hole of the sub-hole supporting piece; the clamping piece comprises a clamping jaw part and a holding part, the clamping piece is provided with a second dowel bar inserting hole penetrating through a body of the clamping piece in the second horizontal direction, the dowel bar is inserted into the supporting ring and the second dowel bar inserting hole, and a sealing ring arranged on the dowel bar in a sleeving mode is arranged between the clamping jaw part and the supporting ring. The dowel bar is clamped by the clamping jaw part, so that the dowel bar is accurately and stably positioned; the arrangement of the sub-hole supporting piece and the clamping jaw part facilitates the assembly and disassembly of the dowel bar; slurry leakage can be obviously reduced; and the compatibility to dowel bars with different specifications is realized.
