Double-legged guyed tower
Technical field:
The utility model relates to the building and the communications field, relates in particular to steel building, particularly iron tower, and concrete is a kind of double-legged guyed tower.
Background technology:
Extensively adopt the Guywire tower of steel work to support cable in the fields such as communication, electric power, radio and television.In the prior art, Guywire tower adopts towline and two kinds of members of body of the tower to carry out combined bay and stands, and body of the tower adopts single pin to link to each other with ground, relies on towline to fix, towline must evenly be arranged at three or four direction, require the area in place bigger, Guywire tower is frequent because the place is former thereby can't set up the construction technology complexity, during on-the-spot the installation, need to regulate the towline of several directions, could guarantee that body of the tower is upright, facade is in disorder in addition.
Summary of the invention:
The purpose of this utility model is to provide a kind of double-legged guyed tower, and described this double-legged guyed tower will solve the towline of Guywire tower in the prior art and arrange the technical problem that floor space is big, construction technology is complicated and facade is in disorder.
This double-legged guyed tower of the present utility model is made of body of the tower and two backguys, wherein, described body of the tower is fixedlyed connected with two column foots by a center-pole and is constituted, the central axis of described center-pole is vertical with line between two column foots, the central axis of center-pole is arranged on the mid point of line between two column foots, any one described column foot all is connected with a body of the tower basic part by articulated structure separately, the upper end of described two backguys is connected to the both sides of sustained height position on the center-pole, the lower end of two backguys is connected with a guyed foundation stake separately, and two backguys become 180 degree angles in horizontal plane.
Further, described two backguys are respectively perpendicular to the line between two column foots.
Further, the upper end of described body of the tower is provided with antenna and lightning rod.
Further, any one described column foot all is connected with described body of the tower basic part by hinge separately, and the axis of described hinge all is located along the same line.
Further, described center-pole and two column foots are made of by welding angle steel.
Perhaps, described center-pole and two column foots are connected and composed by bolt and flange arrangement by steel pipe.
Further, described backguy is steel hinge line or wire rope.
Operating principle of the present utility model is: hinged between two column foots and the basis, the axis of column foot hinge is located along the same line, and the center shaft can be along the line between column foot as rotational.The backguy body of the tower can adopt trussed construction or steel tubular structure, and planar direction has guaranteed enough intensity and stability, does not need backguy to fix; Two backguys be arranged on and column foot between the perpendicular direction of line on, can effectively support direction outside the plane.Guywire tower when mounted, can be on ground in the face of body of the tower carry out assembly unit, carry out being connected of column foot and basis then, again by backguy with the body of the tower pull-up, the stressed verticality even and body of the tower of stay cord for the treatment of both direction reaches requirement and gets final product.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with two column foots in Guywire tower, and is connected through the hinge between column foot and the body of the tower basis, only need get final product perpendicular to the hinge axes direction backguy being set, and has reduced the difficulty of processing of Guywire tower, and is easy for installation, good looking appearance.

The specific embodiment:
Embodiment 1:
Shown in Fig. 1 and Tu, double-legged guyed tower of the present utility model is made of body of the tower 1 and two backguys 2, wherein, described body of the tower 1 is fixedlyed connected with two column foots 4 by a center-pole and is constituted, the central axis of described center-pole is vertical with line between two column foots 4, the central axis of center-pole is arranged on the mid point of line between two column foots 4, any one described column foot 4 all is connected with a body of the tower basic part 5 by articulated structure separately, the upper end of described two backguys 2 is connected to the both sides of sustained height position on the center-pole, the lower end of two backguys 2 is connected with a guyed foundation stake 3 separately, and two backguys 2 become 180 degree angles in horizontal plane.
Further, described two backguys 2 are respectively perpendicular to the line between two column foots 4.
Further, the upper end of described body of the tower 1 is provided with antenna 6 and lightning rod 7.
Further, any one described column foot 4 all is connected with described body of the tower basic part 5 by hinge separately, and the axis of described hinge all is located along the same line.
Further, described center-pole and two column foots 4 are made of by welding angle steel.
Perhaps, described center-pole and two column foots 4 are connected and composed by bolt and flange arrangement by steel pipe.
Further, described backguy 2 is steel hinge line or wire rope.
Operating principle of the present utility model is: hinged between two column foots 4 and the basis, the axis of column foot 4 hinges is located along the same line, and the center shaft can be along the line of 4 of column foots as rotational.Backguy 2 bodies of the tower 1 can adopt trussed construction or steel tubular structure, and planar direction has guaranteed enough intensity and stability, do not need backguy 2 fixing; On the direction that two backguys 2 are arranged on and the line of 4 of column foots is perpendicular, can effectively support direction outside the plane.Guywire tower when mounted, can be on ground in the face of body of the tower 1 carry out assembly unit, carry out being connected of column foot 4 and basis then, again by backguy 2 with body of the tower 1 pull-up, the stressed verticality even and body of the tower 1 of stay cord for the treatment of both direction reaches requirement and gets final product.
