Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 4 and Figure 5, the disclosed electric power pylon foundation connection structure of the utility model, comprise top board 1, truss 2 and basis 3, described top board 1 is connected in truss 2 tops, described truss 2 bottoms are connected with basis 3, described truss 2 is in tilted layout, both tilt the main material of the line 20 of truss upper and lower opening central point and connected electric power pylon shank 4 in the same way, and the line 20 of truss upper and lower opening central point is less than the angle of the main material 4 of this electric power pylon shank and vertical direction with the angle of the main material extended line 40 of connected electric power pylon shank.
Truss 2 is in tilted layout and refers to that the line of truss 2 upper shed central points and under shed central point is not perpendicular to the ground.For making truss 2 stressed more balanced, the end of the main material 4 of electric power pylon shank is generally positioned on truss 2 upper shed central points.And above-mentioned " the main material of the line 20 of truss upper and lower opening central point and connected electric power pylon shank 4 both tilt in the same way ", the angle of inclination that not refers to both is consistent, and refer to that both tilt towards same direction with respect to vertical direction, and both angles of inclination are not necessarily identical, the angle of inclination of the line 20 of truss upper and lower opening central point can be greater than, be less than or equal to the angle of inclination of the main material of electric power pylon shank.When the line 20 of truss upper and lower opening central point and the main material of connected electric power pylon shank 4, both tilt in the same way, truss 2 is subject to the horizontal applied force of electric power pylon and the moment of flexure that vertically active force the forms part of just can cancelling out each other.Be positioned at the desirable rod shaped structure on its main material if regard electric power pylon shank as center of gravity, can draw, in the time that the line 20 of truss upper and lower opening central point equals the angle of the main material 4 of this electric power pylon shank and vertical direction with the angle of the main material extended line 40 of connected electric power pylon shank, the moment of flexure that the suffered electric power pylon pressure of truss 2 forms be identical when the truss 2 moment of flexure size that suffered electric power pylon pressure forms during for vertical truss, institute thinks and reduces the suffered moment of flexure of truss 2, the line 20 of truss upper and lower opening central point is less than the angle of the main material 4 of this electric power pylon shank and vertical direction with the angle of the main material extended line 40 of connected electric power pylon shank, now, under the same conditions, the suffered moment of flexure of inclination truss is less than the suffered moment of flexure of vertical truss.
In fact, the optimum tilt angle of truss 2 is for making it just in time cancelled out each other by electric power pylon horizontal applied force and the moment of flexure that vertically active force forms, so need according to actual electric power pylon calculate its horizontal applied force that truss 2 is produced and vertical active force, more just can calculate accordingly the optimum tilt angle of truss.But above-mentioned calculating best angle need be considered many factors, practical operation comparatively bothers, for making design and construction all convenient, as optimal way, the line 20 of described truss upper and lower opening central point is located along the same line with the main material extended line 40 of connected electric power pylon shank.So not only design and construct simplyr, and in very large limit, having reduced the suffered moment of flexure of truss, operability and feasibility are higher.
