A typical example is a square tower with a rectangular cross section (B in the figure).
Square tower is for general-many. Both those structural axes of one side and the Y-axis direction of the body coincides with the line direction (identity), the direction of the to-wire path by a square tower about the strength of the body structure member, and the strength of the perpendicular direction thereto equally,
For a square tower, the strength in the direction of the electric line and in the direction perpendicular to it

る。[Problems to be Solved by the Invention] Conventionally , transmission line support
It assumed load when performing structural design (towers) (vertical, horizontal)
Among the conditions applied wind loads, and if the wind towards <br/> direction perpendicular to the electric line, in the case of direction or 60 ° parallel thereto
The calculation is performed for the case from the direction of, and the assumed load in each direction is different, but for the plane truss analysis based on the idea that the four main landing gear members and the four abdominal members always correspond, The strengths of the four main pillar members and the four abdominal members constituting the skeleton are equal to each other, and are strengths that can withstand the maximum load. On the other hand , the vertical load of the total actual load (less than 20%)
Is always equally applied to all the main pillars and web members, but among the horizontal loads (more than 80% of the total), the wind pressure load is the one due to the wind perpendicular to the wireway (direct wind pressure). Depending on the type of support, the angle of the wind at which the wind load becomes maximum is linear,
60 degrees to the line direction at an angle tower (oblique wind), the dead-end towers is the direction of 90 degrees (straight wind pressure). for that reason,
The most frequently used straight and angle pylons are most severe in oblique winds
Load condition, the structural arrangement corresponding to this, that is,
Oblique wind opposition is most effective. 1. In conventional towers, the identity (Y structure axis is
If it is built on the line), worked load due from just 45 ° direction in a square tower to <br/> wind, 2 on wind direction line (diagonal line)
And the main pillar material of the present, belly material which is adjacent to this is the stress burden,
Other main pillar two no stress strain (tensile and compressive forces phase <br/> killing) for, two legs in the overload state from the two design stress
There was a potential problem of strength instability such as response . Therefore, always
In places with frequent oblique winds, the main body of the tower is installed in the oblique wind direction (approx.
(75 degrees) to face the oblique winds
It is a target. 2. However, by rotating the body, the body and the wire
The distance between the wires is shortened (closer) and insulation coordination cannot be maintained
And the size of the arm has to be lengthened. 3. When the main body is rotated,
When the wind blows from the direction, the two main pillars
As imbalance problem (reverse effect) where power concentrates occurs, it is perfect
It is not an effective measure, and it is a countermeasure for all wind directions, that is, regardless of the wind direction.
It is necessary to establish a tower structure that can handle four legs. 4. Rebuilding (the under position of a conventional rectangular tower (square-rectangular)
If obtaining bulk up) one shape, for accessing or polymer basis of old and new, as in FIG. 5 A, new basal body and tower body, parallel implementation of removal work was accompanied Tsu danger is difficult. 5 . Tower body width c of the two-line pylons as shown in FIG. 4 A is an arm of a steel tower
Minimum insulation distance between the tower body during swing next to the wire which is supported with gold
Although the Ru twice the spacing der plus body width a of length b of the cross-arm which is a reference, a percentage of the tower body width c of the body width a, 77
About 15% by ~154KV class, there about 20% 220~275KV class, the required distance between two of the wire cross-two-line (top
The ratio to the small insulation interval) is even larger,
Since the ratio increases in both cases, the under-line occupancy land width also increases . In recent years, the width of the main body has become
And the land width has been widened and the land cost has risen.
The problem is that it is difficult to secure land. 6 . Since the magnitude <br/> physician and the wire electric wire slack angle θ in the conventional suspension tower as in FIG. 6 approaches the arm-hanging member when swung to the tower side, the upper and lower cross-arm distance l for security spaced securing was necessary Tsu there to take greater than between <br/> interval of the standard tower. There are various problems such as,
The conventional tower structure is not an efficient and practical structural arrangement according to the actual situation. The present invention corrects these problems.
(Eliminated, improvements), and aims to enhance the effectiveness.

The upper body has a rhombic or rhombic shape,
The lower main book which made the main column material of 8 branches into the inverted Y type
By using a steel tower with an octagonal body shape
The two main pillars that do not bear the stress during the sloping wind bear the stress
Then, the stress of the other two main pillars that are overloaded is also divided,
All legs are always balanced (load in all wind directions)
(8) can be handled, the lower body section is octagonal
As a result, the projected area at the time of oblique wind is also reduced by 35%
