[0002] The truss is a supporting beam structure composed of rods connected by welding, riveting or bolts. The truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material and save material compared with the solid web beam when the span is large. , reduce self-weight and increase rigidity. In modern buildings, steel trusses composed of steel pipes are mostly steel trusses, and steel trusses composed of steel pipes are widely used in large buildings because of their large bearing capacity and flexible layout. In the span and large cantilever structure, but in the construction of the truss structure, the connection between the nodes of the general truss structure is not firm, and it is easy to cause plastic deformation in the truss structure, resulting in the instability of the truss structure, which makes the use of the truss subject to certain restrictions. limit

Embodiment Construction
[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings, which are simplified schematic diagrams, only schematically illustrating the basic structure of the present invention, and therefore only show the configurations related to the present invention.
[0015] Such as figure 1 The preferred embodiment of the truss structure of the present invention shown includes a truss body 1, the truss body 1 adopts a U-shaped structure, and a prestressed cable 2 is installed in the truss body 1, and the bottom of the prestressed cable 2 is fixed on the truss body 1. The side of the truss body 1 is provided with a truss single piece 3, and the truss single piece 3 and the truss body 1 are tenon-jointed. The truss body 1 and the middle part of the truss single piece 3 are provided with a prestressed tie rod 4, and there are two prestressed tie rods 4. The two ends of the two prestressed tie rods 4 are horizontally arranged on the tr...

The invention discloses a truss structure. The truss structure comprises a truss body which is in a U-shaped structure. Pre-stress pulling cables are arranged in the truss body, the bottoms of the pre-stress pulling cables are fixed on the truss body, and truss single sheets are arranged on the sides of the truss body and are in mortise connection with the truss body. Two pre-stress pull rods are arranged in the truss body in the middles of the truss single sheets, and the two ends of the pre-stress pull rods are arranged on the truss body transversely. Stress rods are arranged between the two pre-stress pull rods, and reinforcing bolts are arranged between the stress rods and the pre-stress pull rods. An anchorage plate is arranged at the inner bottom of the truss body and is hinged to the truss body. The truss structure is tight in overall connection and safe and stable, occupied space is saved to a large extent when the middle truss depth is increased, the tensile part stress condition is improved, the tensile part is in a relatively balance stress form, the truss rigidity is improved, and the truss deformation is reduced.
