Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram on the utility model prefabricated pile chassis.
Specific embodiment
Embodiment:
The structural schematic diagram of the utility model is as shown in Figure 1, 2, the utility model for photovoltaic power plant bracket basis
Anti-pulling piling bar, includes steel tube prefabricated stake 1, screw-thread steel 2, prefabricated pile chassis 3, wherein the top of steel tube prefabricated stake 1 with it is prefabricated
Stake chassis 3 connects, and the middle part of steel tube prefabricated stake 1 is equipped with orthogonal two through-holes, and two screw-thread steels 2, which are each passed through, mutually to hang down
Two straight through-holes, and be welded in steel tube prefabricated stake 1.The effect of two screw-thread steels 2 is in the concrete offer in addition to pedestal
Except tension pull out force, is relied on using orthogonal screw-thread steel and increased again with the contact of soil layer (or stone) from different directions
Tension pull out force.The existing piling bar connecting with photovoltaic bracket, general piling bar need to weld the components such as special connector, the utility model
Anti-pulling piling bar with bracket be to be directly connected to, it is succinct convenient, securely；It and is multiple anti-pulling structure, the plating of anti-pulling piling bar
Zinc pipe can be avoided secondary preservative treatment.The anti-pulling steel pile structure of the utility model is simple, but anti-pulling effect is brighter
Aobvious, by chassis casting concrete, screw-thread steel is welded in middle position, after soil layer backfill, passes through concrete block intensity, backfill
Soil layer gravity, photovoltaic bracket component gravity and utilization the utility model anti-pulling steel pile structure increase contact area in different location
To increase tension pull out force.
In the present embodiment, be separated by between orthogonal two through-holes for being equipped in the middle part of above-mentioned steel tube prefabricated stake 1 120mm~
180mm。
In the present embodiment, it is separated by 150mm between orthogonal two through-holes for being equipped in the middle part of above-mentioned steel tube prefabricated stake 1.
In the present embodiment, the bottom and prefabricated pile chassis 3 of above-mentioned steel tube prefabricated stake 1 are welded.
