Specific embodiment
As Figure 1-Figure 4, the square concrete hollow column of centrifugal forming prestressing force, including centrifugal forming concrete hollow column
1, the deformed bar 2 of pre-tensioning system tensioning is provided with concrete hollow column 1, deformed bar 2 is along concrete hollow
The length direction of post is set, and deformed bar 2 is distributed on the circumference of concrete hollow column 1, along the length side of concrete hollow column 1
To nonprestressed reinforcement 3 is additionally provided with, deformed bar 2 and nonprestressed reinforcement 3 are located at same square upper and are alternately arranged,
Square diagonal overlaps with the diagonal of concrete hollow column 1, nonprestressed reinforcement 3 be arranged on the two ends of concrete hollow column 1
End plate 5 is connected, and in the stirrup that is circumferentially provided with of deformed bar 2, stirrup is connected with deformed bar 2, in concrete hollow column 1
End be provided with cuff 4.
Stirrup is covered with the axial direction of deformed bar 2, and the spacing for being arranged in the stirrup at the two ends of deformed bar 2 is 75mm, its
The spacing of remaining stirrup is 200mm.That is, the stirrup I 6 that spacing is 75mm is disposed with the two ends of deformed bar 2, in center section
Arrangement is that spacing is the stirrup II 7 of 200mm.
Nonprestressed reinforcement 3 uses straight screw connection with end plate 5.
Stirrup is connected with deformed bar 2 using spot welding.
When the square concrete hollow column of centrifugal forming prestressing force carries out industrialized production, prestressing force is determined according to calculating first
The radical of reinforcing bar 2 and nonprestressed reinforcement 3, diameter, length, then using pre-tensioning system while casting concrete open tubular column 1,
Pre-buried deformed bar 2 simultaneously completes tensioning, tensioning by the way of upsetting anchor is first opened, 3-3 sectional drawing of the cage bar anchor hole 8 such as in Fig. 4
Shown, nonprestressed reinforcement 3 is with end plate 5 by the way of straight screw connection.Nonprestressed reinforcement 3 is used with deformed bar 2
Along the mode that the surrounding of concrete hollow column 1 is alternately arranged, as shown in Fig. 3 sections 2-2.Stirrup and cage bar use the mode of spot welding with
