Embodiment
Embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings, embodiment is not constituted to limit of the present utility model
System：
Curve modular expansion device side bar, it is characterised in that comprising edge-beam section steel, the edge-beam section steel is arc knot
Structure, the edge-beam section steel avris is included between the wall for including and projecting in parallel out above and below holding tank, the holding tank, two walls
For holding tank.The substantive technique effect and its implementation process that the technical scheme at this place is played are as follows：It is directed to existing skill
The defect of art：" traditional side bar steel is unable to reach effective combination with beam body concrete, and anchor system is weak, causes device and beam body
Depart from and damage；”；Bigger using two walls, and the contact area of concrete, clamping effect is more preferable.Unlike original structure is one
Individual wall, clamping effect is bad, and this patent enables side bar and concrete to combine fastening closely, is not easily disconnected from, is hardly damaged.Together
When, arcuate structure has the advantage that, the gap of arc is not the direction advanced perpendicular to wheel, the extruding side that wheel is advanced
It is not straight line to the direction of propagation with sound wave, overall vibration frequency is small, and noise is small.Curve Design reduces vehicle operation
In direct impact to retractor device, reduce noise, improve road-ability, play a part of environmentally friendly noise reduction.
Angle below this described holding tank is acute angle.Substantive technique effect that the technical scheme at this place is played and in fact
Existing process is as follows：More preferably, overall clamping effect is more preferable for the combination effect of acute angle.
The edge-beam section steel avris includes more than one waterstop pockets.More than one, preferably two.
The edge-beam section steel top includes anti-slip tank.Substantive technique effect that the technical scheme at this place is played and in fact
Existing process is as follows：Anti-slip tank energy increasing friction force so that the more steady safety of overall structure operation.
The waterstop pockets include raised tangent plane.Substantive technique effect that the technical scheme at this place is played and
