The utility model content
At the defective that exists in the above-mentioned prior art, it is big that technical problem to be solved in the utility model provides a kind of span, can be used for the concrete tension string beam structure of long span building thing.
In order to solve the problems of the technologies described above, a kind of concrete tension string beam structure provided by the utility model, comprise concrete beam and prestressing tendon, the two ends of described concrete beam are fixed on the column that lands, and it is characterized in that: the below of described concrete beam is provided with two vertical struts;
The upper end of described two vertical struts connects concrete beam with mode of rigidly connecting or articulated manner;
Described prestressing tendon passes the end, lower end of two vertical struts, and its two ends are anchored at the two ends of concrete beam respectively through stretching and anchoring device.
Further, the upper end of described two vertical struts connects concrete beam in the mode of rigidly connecting; The end, lower end of described prestressing tendon and two vertical struts is slidingly connected.
Further, the upper end of described two vertical struts connects concrete beam in hinged way; The end, lower end of described prestressing tendon and two vertical struts is affixed.
Further, described concrete beam is the real abdomen formula of a concrete wide-flat beam.
Further, described concrete beam is a concrete boxlike beam, is provided with two floors in its inner chamber, described two floors lay respectively at two vertical struts directly over, the two ends up and down of every floor are affixed with concrete beam respectively.
Further, the big up and small down trapezoidal shape of the shape of described vertical strut.
Further, described prestressing tendon is the finished product prestressed cable, or the drag-line of being made up of unbonded prestressing tendon, or prestressed draw-bar.
The concrete tension string beam structure that the utility model provides, because concrete beam has adopted the form of external prestressing, and employing tension string beam structure, realize turning to and supporting of prestressing tendon with vertical strut, concrete beam is as bending component, mainly bear pressure, bear moment of flexure on a small quantity, vertical strut bears a power and moment of flexure between concrete beam and prestressing tendon, prestressing tendon combines with concrete beam in the end, two ends of concrete beam, form self equilibrium systems, bearing is not produced extra horizontal thrust, therefore compare existing prestressed concrete beam and have bigger span, can satisfy the force request of long span building thing.
