Detailed Description
As shown in fig. 1 to 3, a high-speed railway bridge deck ballast wall shear reinforcement installation device is composed of reinforcements 3, wherein:
shear connection reinforcing bar 1: each shear-resistant connecting steel bar is formed by sleeving a 650mm long steel bar 3 with a diameter of phi 20 into a PVC sleeve 2 with a diameter of 24-25 mm, and two ends of the PVC sleeve are sealed. The shear resistant connecting steel bars are three.
Side splint 4: the rectangular steel plate is 3mm thick, 400mm wide and 1000mm long, 3 gaps 5 which are 163mm long are arranged on the long edge of one side of the rectangular steel plate at intervals, the gaps extend to the axial lead side of the rectangular steel plate, the inner ends of the gaps are semicircular, and the number of the side clamping plates is two.
An intermediate splint 6: the rectangular steel plate is 4mm thick, 210mm wide and 1000mm long, 3 gaps 7 with the length of 73mm are arranged on the long edge of one side of the rectangular steel plate at intervals, the gaps extend to the axial lead side of the rectangular steel plate, the inner end of each gap is semicircular, and the middle clamping plate is one.
The middle splint is positioned between the two lateral splints on the same-direction opening edge, and the two lateral splints on the same-direction opening edge are closely attached to the middle splint on the opposite opening edge. And the corresponding gaps which are closely attached in opposite directions are aligned to form three gap holes 8 which are arranged at intervals and are used for the shearing-resistant connecting steel bars to pass through. The middle parts of the three shear-resistant connecting steel bars are respectively positioned in each opening hole, and the two ends of the three shear-resistant connecting steel bars are fixed (bound by iron wires at the intersection) with the steel bars 9 on the steel bar net rack of the ballast wall at the corresponding part into a whole.
As shown in FIG. 5, when the PVC sleeve pipe is used, firstly, 650mm long phi 20 shear-resistant connecting steel bars are sleeved into PVC sleeve pipes with the diameters of 24-25 mm (so as to ensure that two adjacent ballast walls stretch out and draw back), and two ends of each PVC sleeve pipe are sealed by adhesive tapes (so as to prevent slurry from entering in the concrete pouring process). The middle splint is positioned between the two lateral splints on the same-direction opening edge, and the two lateral splints on the same-direction opening edge are closely attached to the middle splint on the opposite opening edge. And the corresponding gaps which are closely attached in opposite directions are aligned to form three gap holes 8 which are arranged at intervals and are used for the shearing-resistant connecting steel bars to pass through. The middle parts of the three shear-resistant connecting steel bars are respectively positioned in each opening hole, and the two ends of the three shear-resistant connecting steel bars are fixed (bound by iron wires at the intersection) with the steel bars 9 on the steel bar net rack of the ballast wall at the corresponding part into a whole.
