Abstract
The utility model relates to a tower which is made of metal, comprising a plurality of polygonal tapered steel tubes which are inserted in sequence, wherein, the upper part of the steel tube is fixed with a cross arm; the bottom part of the steel pipe is fixed with a flange plate; the flange plate is fixed with a ribbed slab with is connected with the tapered steel tube; the number of the tapered steel tubes is eight, or twelve or sixteen. The pinboard polygonal taper steel tube tower does not have circumferential welds and has the advantages of high safety, strong performance of wind resistance and long service life.
Description
The utility model relates to the tower of making of metal.
The tower of the usefulness that transmits electric power in the power supply network, traditional form of structure is iron tower, and the iron tower floor space is big, and consume material is many, the cost height.In recent years developed the steel tube tower that has the multiple tracks girth joint on a kind of tower bar, the deficiency of this steel tube tower is: 1 girth joint is that the hidden danger of accident is deposited ground, poor reliability, and safety factor is low; When 2, at the construction field (site) welding being installed, the anticorrosive coat of welding zone is damaged, and directly has influence on the application life of tower.
The purpose of this utility model is the polygon conical steel pipe tower of plug-in type of a kind of not band weld seam of design.
The polygon conical steel pipe tower of this plug-in type comprises the tower bar, and the top of tower bar is fixed with cross-arm, and its design feature is that the tower bar is the polygon conical steel pipe that more piece is pegged graft successively, is fixed with flange in the bottom of next pitch cone shape steel pipe.
For making this steel tube tower firmer, on flange, be fixed with the gusset that is connected with the external surface of next pitch cone shape steel pipe, the length that tapered steel tube coupling and joint are pegged graft is 1.5 times of plugging position average diameter.The limit number of conical steel pipe can be eight limits, twelve edge or ten hexagons, and it is high that the height of tower bar can be pegged graft into 20-80 rice according to user's needs.
The polygon conical steel pipe tower of this plug-in type, owing to there is not girth joint, structural strength is big, good reliability, safety factor height; Because the off-centre of structural member connects few.Stressed evenly wind pressure value is little, and wind loading rating is strong, and is difficult for accumulated snow; Socket connection between joint and the joint, speed of application is fast, does not destroy the anticorrosive coat of outer surface of steel tube, has prolonged application life.
Accompanying drawing shows the embodiment of the polygon conical steel pipe tower of plug-in type, and wherein Fig. 1 is the structural representation of embodiment, and Fig. 2 is the A-A sectional view of Fig. 1.
In the present embodiment, the polygon conical steel pipe tower of plug-in type comprises tower bar 1, the top of tower bar 1 is fixed with four cross-arms 2, tower bar 1 is the eight limit conical steel pipes that three joints are pegged graft successively, be welded with flange 3 in the bottom of next pitch cone shape steel pipe, be welded with on the flange 3 with the external surface of next pitch cone shape steel pipe and fixedly connected and eight uniform gussets 4.
Claims (4)
1. the polygon conical steel pipe tower of plug-in type comprises tower bar (1), and the top of tower bar (1) is fixed with cross-arm (2), it is characterized in that the polygon conical steel pipe that tower bar (1) is pegged graft successively for more piece, is fixed with flange (3) in the bottom of next pitch cone shape steel pipe.
2. according to the polygon conical steel pipe tower of the said plug-in type of claim 1, it is characterized in that on flange (3), being fixed with the gusset (4) that is connected with the external surface of next pitch cone shape steel pipe.
