The utility model aims at providing a transmission of electricity steel tower crossing tower leg structure to solve among the prior art transmission of electricity steel tower and set up when the slope is great or the biggest difference in grade increases in needs, the design angle of main material and material to one side is difficult to satisfy the problem that the atress required.
The embodiment of the utility model is realized like this:
the crossed tower leg structure of the power transmission steel tower is characterized in that the upper end of an oblique material of any one of two legs on the front surface of the power transmission steel tower is supported and connected below a connecting node of a main material and a partition surface of the other leg, so that the two oblique materials are arranged in a crossed manner; and the inner stay bars between the first sections above the partition surface are arranged in a crossed manner, so that the lower ends of the inner stay bars are supported on the connecting nodes of the main material and the partition surface.
The crossed tower leg structure of the power transmission steel tower in the scheme can enable the terrain gradient which can be adapted to the front surface of the tower leg to be 56 degrees from the original 36 degrees, greatly improves the adaptability of the iron tower to the steep terrain, and reduces or avoids the earthwork workload of the steep terrain under the condition of meeting the leg main oblique material included angle.
In one embodiment:
one continuous oblique material and the other continuous oblique material are disconnected and fixedly connected with the continuous oblique material at the fracture.
In order to keep the two inclined materials coplanar, only one of the two inclined materials needs to be disconnected and then connected to the continuous one through welding or other methods, so that the two inclined materials can be connected in a cross mode while the two inclined materials are kept coplanar.
In one embodiment:
the longer one of the two inclined materials is disconnected, and the shorter one is continuous.
By making the break longer, the compression stability of each segment can be improved.
In one embodiment:
the main material and the inclined material are both made of angle steel.
In one embodiment:
the angle steels of the main material and the inclined material are connected in a way that the limbs face inwards.
In one embodiment:
the lengths of the two leg parts are matched with the gradient of the setting position of the power transmission steel tower.
