Below the further technical scheme of the utility model is described.
The described first adjacent oblique connecting rod is parallel to each other, and the described second adjacent oblique connecting rod is parallel to each other.
Past more upper end, the distance between described first montant, second montant, the 3rd montant and the 4th montant is near more.
Between described first montant and second montant, between second montant and the 3rd montant, between the 3rd montant and the 4th montant, between the 4th montant and first montant, between first montant and the 3rd montant, also be connected between second montant and the 4th montant by horizontal connecting rod.
Described crossbeam comprises four cross bars, i.e. first cross bar, second cross bar, the 3rd cross bar and the 4th cross bar, the line in the cross section of first cross bar, second cross bar, the 3rd cross bar and the 4th cross bar forms rectangle, between first cross bar and second cross bar, between second cross bar and the 3rd cross bar, between the 3rd cross bar and the 4th cross bar, all be connected by many first oblique connecting rods and many second oblique connecting rods between the 4th cross bar and first cross bar, and the first adjacent oblique connecting rod intersects with the second oblique connecting rod.
Described pylon is three, is supported on the two ends and the stage casing of described crossbeam respectively.
Between described first cross bar and second cross bar, between second cross bar and the 3rd cross bar, between the 3rd cross bar and the 4th cross bar, between the 4th cross bar and first cross bar, between first cross bar and the 3rd cross bar, also be connected between second cross bar and the 4th cross bar by horizontal connecting rod.
Below advantage of the present utility model is described.
1, because pylon adopts four montants, and connect by many first oblique connecting rods, the second oblique connecting rod between four montants, make the stable three-legged structure of formation between four montants and the first oblique connecting rod, the second oblique connecting rod, can bear bigger power, and the integrally-built intensity of pylon is higher.
2, after the employing aforementioned structure, angle between four montants of pylon can be far smaller than the angle of gable column in the existing structure, under the situation of equal height, can reduce the area of pylon bottom greatly, and then the floor space of minimizing framework, simultaneously, the diameter of four montants and the first oblique connecting rod, the second oblique connecting rod can reduce, and has alleviated the weight of framework.
