Embodiment Construction

[0025] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0026] figure 1 It is a flow chart of the construction method of the reinforced concrete pavement shrinkage joint structure of the present invention.

[0027] see figure 1 , a construction method of reinforced concrete pavement shrinkage joint structure, comprising the following steps:

[0028] S1 Set out the position of the shrinkage joint area in advance on the construction site, bind the concrete pavement steel bars, the bound steel bars are bounded by the shrinkage joints and disconnected at the shrinkage joints, and the distance between the steel bars on both sides is 30mm after disconnection.

[0029] S2 Install dowel brackets on both sides of the steel bar break, provide a plurality of inverted "V"-shaped bars, the inverted "V"-shaped bars include two free ends and a connectin...

Abstract

The invention provides a concrete pavement reinforced shrinkage crack structure. The concrete pavement reinforced shrinkage crack structure comprises a shrinkage crack area, a broken area formed in the shrinkage crack area by reinforcing steel bars of a concrete pavement, force transfer rod brackets arranged at the two sides of the broken area, and force transfer rods arranged on the force transfer rod brackets. The invention provides the concrete pavement reinforced shrinkage crack structure and a construction method thereof; the reinforcing steel bars in a concrete surface layer in shrinkage cracks are broken, and the middle broken positions are connected by the force transfer rods, so that the shrinkage cracks are preferably shrunk, and the cracks are prevented; and the force transfer rods can connect concrete at the two sides of the shrinkage cracks so as to guarantee no break of the concrete in the shrinkage cracks.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a concrete pavement reinforced shrinkage joint structure and a construction method thereof. Background technique [0002] Cement concrete pavement refers to the pavement with concrete as the main material, referred to as concrete pavement, which is a kind of high-grade pavement. However, concrete is shrinkable, and surface cracks will appear on the road surface due to shrinkage. How to control surface cracks is a major problem in concrete pavement. The conventional method is to set shrinkage joints. Conventional shrinkage joints are slits cut by a slitting machine, but the slits cannot maximize their effect due to the presence of steel bars in the road surface. Contents of the invention [0003] In order to overcome the defects existing in the prior art, the object of the present invention is to provide a concrete pavement reinforced shrinkage joint s...
