Further, the width of the stress slit is 1 mm. The too big holding power that can reduce the body of rod of width of stress seam, the undersize can reduce the ability of stress seam absorption stress, and the function of absorption stress can be satisfied to 1 mm's stress seam, and the influence can not be very big again to the holding power of the body of rod.
Furthermore, be equipped with many edges in the hollow hole of the body of rod the stress pole that body of rod axis direction set up, many the subsides of stress pole are established the inner wall of the body of rod, many pass through the connecting rod reciprocal anchorage between the stress pole. When the tower deforms due to the influence of natural disasters such as burning sun, strong wind, severe cold and the like, the stress rods can absorb partial stress changes of the tower, the deformation of the tower is reduced, and the possibility of stress cracking of the tower is reduced.
Furthermore, the stress rod and the connecting rod are both made of elastic steel. The elastic steel can absorb part of stress deformation and can restore the original shape to release the stress.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
the shockproof power transmission concrete pole tower is provided with the stress joints, when the pole tower is influenced by natural disasters such as burning sun, strong wind, severe cold and the like to generate stress deformation, the width of the stress joints can be changed to extrude the shockproof strips, and the stress joints and the shockproof strips respectively absorb part of stress, so that the stress deformation of the pole body is reduced, and the stress cracking of the pole body is reduced. The stress ring can keep the holding power of the body of rod stable to the stress deformation direction of the restriction body of rod makes the stress deformation of the body of rod unable outside expansion, makes the stress deformation of the body of rod extend to the stress joint direction, is absorbed by the stress joint at last, thereby reduces the stress cracking of the body of rod. The shockproof power transmission concrete pole tower well solves the problem that the power transmission pole tower is easy to generate stress cracking.
