Abstract
The utility model discloses a long-span steel frame. Most steel frames in the prior art utilizes high number of steel poles, and therefore resource waste is caused, bear load is increased and safety is reduced. The long-span steel frame comprises an upper chord, a lower chord, side poles, slant supporting poles, vertical supporting poles, an adjustment device, a sleeve and a wire rope. The upper chord and the lower chord are horizontally arranged, the two side poles are connected with two ends of the upper chord and two ends of the lower chord respectively, the vertical supporting poles are vertically arranged between the upper chord and the lower chord and distance between each two vertical supporting poles is equal, and the slant supporting poles are arranged within opposite angles with the neighboring vertical supporting poles. The middle position of the lower chord is provided with the sleeve in a fixed mode. Two ends of the wire rope are respectively fixed on the two ends of the upper chord and pass through the sleeve. The wire rope is further provided with the adjustment device, wherein the adjustment device can adjust length of the wire rope. The triangular-structure supporting poles of the long-span steel frame is stable in structure, and pre-stressing force of the steel frame is increased due to arrangement of the adjustable wire rope.
Description
Technical field
The utility model belongs to building field, especially a kind of large span steelframe.
Background technology
Modern architecture is more and more to need the large span steelframe, and the steelframe of large span has necessarily required high strength, and prior art in steelframe mostly adopt the steel pole of high quantity, cause the wasting of resources, bearing a heavy burden increases, safety reduces.
Summary of the invention
The utility model has proposed a kind of large span steelframe for the deficiencies in the prior art.
The utility model large span steelframe comprises upper chord, lower chord, side lever, inclined support bar, vertical support bar, adjusting device, sleeve and cable wire.Described upper chord and lower chord are horizontally disposed with, two side levers connect respectively the two ends of upper chord and lower chord, vertical support bar is vertically set between upper chord and the lower chord, equidistant between the vertical support bar, inclined support bar is arranged between the adjacent vertical support bar diagonal angle, the centre position of lower chord is fixed with a sleeve, and the two ends of cable wire are separately fixed at the two ends of upper chord and pass sleeve, also is provided with adjusting device on the cable wire.Described adjusting device can be regulated the length of cable wire.
The beneficial effects of the utility model: the utility model triangular structure supporting bar structure is stable, and is provided with adjustable cable wire, has increased the prestressing force of the horizontal direction of steelframe.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
