It is equipped with upper layer steel wire, transverse steel layer, longitudinal reinforcement layer and lower layer's steel wire；
Reinforcing bar in longitudinal reinforcement layer extends along 7 length direction of reinforced concrete bed course, and the reinforcing bar in transverse steel layer is along reinforcing bar
7 width direction of concrete bed course extends.
In the present embodiment, the neutralization axial symmetry water of longitudinal reinforcement layer and transverse steel layer about 7 section of reinforced concrete bed course
Flat setting, upper and lower layer steel wire are horizontally disposed about the neutralization axial symmetry in 7 section of reinforced concrete bed course；Transverse steel layer and longitudinal direction
The reinforcing bar of steel bar layer is deformed bar.In each fixed one layer of minor diameter spacer bar layer in the upside of upper and lower layer steel wire, two
Reinforcing bar in spacer bar layer is deformed bar, and the spacing of reinforcement in two lateral minor diameter spacer bar layers is side by side and in parallel
In reinforced concrete bed course 7 plate face be arranged, between interval be greater than adjacent reinforcing bar distance.Reinforcing bar both ends in spacer bar layer are stretched out
7 peripheral end surface of reinforced concrete bed course, when producing reinforced concrete bed course 7, spacer bar layer can be convenient for positioning to upper and lower steel wire.Upper,
Lower layer's steel wire end is located within 7 peripheral end surface of reinforced concrete bed course, i.e., upper and lower layer steel wire does not stretch out reinforced concrete bed course 7 weeks
Side end face；Reinforcing bar in upper and lower layer steel wire is coated reinforcement.
Transverse steel layer can increase reinforced concrete bed course 7 in the width direction on use intensity.Longitudinal reinforcement layer and lateral steel
Muscle layer is horizontally disposed about the neutralization axial symmetry in 7 section of reinforced concrete bed course, and upper and lower layer steel wire is about 7 section of reinforced concrete bed course
Neutralization axial symmetry it is horizontally disposed, it is structurally reasonable, while improving the intensity of reinforced concrete bed course 7, reinforced concrete pad is effectively reduced
The buckling deformation of layer 7.Upper and lower layer steel wire can be used as nonprestressed reinforcement use.In this way, when reinforced concrete bed course 7 does not crack,
Deformed bar can provide prestressing force and increase 7 intensity of reinforced concrete bed course, prevents reinforced concrete bed course 7 from cracking, opens in reinforced concrete bed course 7
When splitting, upper and lower layer steel wire, which can be used as nonprestressed reinforcement, prevents track plates from continuing to crack.And upper and lower layer steel wire is not stretched
7 peripheral end surface of reinforced concrete bed course out keeps 7 surface texture of reinforced concrete bed course more complete, is hardly damaged, improves service life.?
On longitudinal prestressing reinforcing bar, meets technique manufacture and require, longitudinal reinforcement layer, transverse steel interlayer are every setting, and in steel bar layer
Reinforcing bar be also spaced setting so that the reinforcing bar of steel bar layer every is not in contact with each other, upper and lower layer steel wire uses coating insulation steel bar,
It can completely avoid the formation metallic closed circuit in reinforced concrete bed course 7.Reinforcing bar in transverse steel layer is arranged side by side in groups, group
Interior reinforcing bar is no less than three, and compared with single steel bar, no less than 3 reinforcing bars, which are arranged in groups, can reduce deformed bar to concrete
The stress of application.
