Description

Technical Field

[0001] The utility model relates to the technical field of pavement construction equipment, in particular to a tool-type force transmission rod bracket for an airport pavement. Background Art

[0002] The dowel bar refers to the round steel arranged in the middle of the plate at a certain distance at the transverse construction joint of the airport cement concrete pavement. One end of it is fixed in one side plate, and the other end can slide in the adjacent plate. Its function is to transfer aircraft loads between pavement panels and prevent the panels from misaligning, increase the stress transfer between adjacent pavement panels, prevent the pavement panels from being locally subjected to large aircraft impact wheel loads causing uneven settlement of the pavement panels, and transfer stress to make adjacent pavement panels bear force together. The dowel bar is an indispensable and important component of the free end of the airport road pavement.

[0003] At present, the existing traditional pavement dowel rod installation method is to manually insert the dowel rod into the pavement concrete through the reserved holes of the sealing template by hammering during the pavement concrete paving at the sealing position. After the pavement concrete is vibrated, the dowel rod is manually measured and corrected to adjust the position. However, this type of construction method can easily lead to installation deviation, uncertain direction, and time-consuming and labor-intensive manual adjustment of the dowel rod. Therefore, an airport pavement tool-type dowel rod bracket is proposed to optimize and solve the above problems. Utility Model Content

[0007] As a further solution of the utility model: the fixing frame is provided with fixing holes symmetrically and equidistantly.

[0008] As a further solution of the utility model: the limiting sleeve is provided with a through hole for the threaded sleeve to penetrate and connect.

[0009] As a further solution of the utility model: the outer side of the arc-shaped limit block is in contact with and fixedly connected to the inner wall of the mounting frame.
