Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It is a kind of prestressed reinforced concrete screw thread tubular pole disclosed by the utility model referring to figs. 1 to Fig. 2, including answers in advance
Power reinforcing bar 1 and concrete tubular pile 2.
In every section prestressed reinforced concrete screw thread tubular pole, it is provided with eight equally distributed deformed bars 1.Along every
The longitudinal measure of deformed bar 1 in section prestressed reinforced concrete screw thread tubular pole has several stirrups 11, specifically, according to
The length of deformed bar 1, every two meters are welded with a stirrup 11.The stirrup 11 is welded in the outside of deformed bar 1.
The both ends of deformed bar 1 are provided with anchorage 12 with Fig. 4 referring to Fig.1, the pulling force of guarantee deformed bar 1 simultaneously will
It is transmitted to inside concrete tubular pile 2.
By way of centrifugal casting, concrete tubular pile 2 is poured to deformed bar 1, is that deformed bar 1 is located at
In concrete reinforcement.And concrete tubular pile 2 is hollow setting.In the outer wall of concrete tubular pile 2, this has poured screw thread 21, the spiral shell
The width of line 21 is 5cm, with a thickness of 6cm, screw pitch 20cm.Make the contact surface of prestressed reinforced concrete screw thread tubular pole and ground
Product, to increase the frictional force of prestressed reinforced concrete screw thread tubular pole and ground.
Referring to Fig.1 with Fig. 3, the length of the deformed bar 1 is greater than the length of concrete tubular pile 2, makes deformed bar 1
Both ends protrude from the both ends of concrete tubular pile 2.Further include welded disc 4, is uniformly provided with welding hole 41 in welded disc 4, the welding hole
41 aperture and position are with the cross-sectional sizes of deformed bar 1 and position to being adapted to.Welded disc 4 is divided by welding hole 41
Not Tao Jie and in the both ends of deformed bar 1, and welded disc 4 is made to be located at the both ends of concrete tubular pile 2.
Welded disc 4 and concrete tubular pile 2 backwards be fixed with limited block 42 and limiting slot 43 on one side, limiting slot 43 it is big
The small size with limited block 42 is adapted.Limited block 42 and limiting slot 43 staggeredly and be uniformly distributed in welded disc 4.Make in pile extension
When by limited block 42 and limiting slot 43, fix the position of two section prestressed reinforced concrete screw thread tubular poles, and welded.
Pile top 3 is welded in the welded disc 4 of 2 one end of concrete tubular pile.Pile top 3 is in coniform, the ground welding of pile top 3
In in the welded disc 4.
The implementation principle of the present embodiment are as follows:
When making prestressed reinforced concrete screw thread tubular pole, corresponding number is chosen according to the length of deformed bar 1
Stirrup 11, and deformed bar 1 is welded in along longitudinal direction in stirrup 11.In the fixed anchorage 12 in the both ends of deformed bar 1, make pre-
The pulling force of stress reinforcing bar 1 simultaneously passes it to inside concrete tubular pile 2.
After making deformed bar 1, the concrete tubular pile 2 with screw thread 21 is poured to deformed bar 1, and is made
