Hanging truss suitable for large-span floor

Abstract

The utility model discloses a hanging truss suitable for large-span floor relates to the field of steel structure, including two vertical installation in the building both sides of the weighing ware fixed plate, the opposite face of two fixed plates all are fixedly connected with two upper and lower distribution's support seat, horizontal direction corresponding two support seat between fixedly connected with crossbeam and located under the arch beam of crossbeam, fixedly connected with a plurality of connecting frames between the arch beam and crossbeam. Advantageous effects lie in: through the cooperation of fixed plate and U-shaped support seat, realize the stable constraint to crossbeam, arch beam end, U-shaped support seat can wrap crossbeam, arch beam end, effectively prevent end slip or twist, the inclined pull rod provides the inclined upward tension for crossbeam, and the lifting assembly provides the upward tension compensation for arch beam, makes truss carrying capacity improve significantly.

Claims

1. A suspended truss suitable for large-span floors, characterized in that: It includes two vertically mounted fixed plates (4) on the weighing devices on both sides of the building. The opposite surfaces of the two fixed plates (4) are fixedly connected to two vertically distributed support seats (5). A crossbeam (1) and an arch beam (2) located below the crossbeam (1) are fixedly connected between the two support seats (5) in the horizontal direction. Several connecting frames (3) are fixedly connected between the arch beam (2) and the crossbeam (1). A lifting assembly (7) is fixedly connected to the fixed plate (4) to provide upward tension to the arch beam (2). The lifting assembly (7) includes a steel cable (11) fixedly connected between the fixed plate (4) and the arch beam (2) and a guide rail (14) for supporting the steel cable (11).

2. The suspended truss suitable for large-span floors according to claim 1, characterized in that: The fixed plate (4) and the crossbeam (1) are fixedly connected by an inclined tie rod (6).

3. The suspended truss suitable for large-span floors according to claim 2, characterized in that: The end face of the diagonal tie rod (6) is cross-shaped.

4. The suspended truss suitable for large-span floors according to claim 1, characterized in that: The support base (5) is U-shaped and is used to support the ends of the crossbeam (1) and the arch beam (2).

5. The suspended truss suitable for large-span floors according to claim 1, characterized in that: A detection component (8) is provided between the two fixed plates (4) for detecting whether the crossbeam (1) is deformed.

6. The suspended truss suitable for large-span floors according to claim 5, characterized in that: The detection component (8) includes two tension sensors (9) hinged on the crossbeam (1). The force-bearing end of the tension sensor (9) is fixedly connected to the corresponding fixing plate (4) through the pull rope (10), and the pull rope (10) is in a taut state.

7. The suspended truss suitable for large-span floors according to claim 1, characterized in that: The connecting frame (3) is vertical between the crossbeam (1) and the arch beam (2).

8. The suspended truss suitable for large-span floors according to claim 1, characterized in that: The lifting assembly (7) includes a V-shaped frame (12) fixedly connected to the fixed plate (4). The tip of the V-shaped frame (12) is fixedly connected to the fixed plate (4) with a guide rail (14) at an incline. The bottom of the V-shaped frame (12) is fixedly connected to the fixed plate (4) with a support rod (13) at an incline.

9. The suspended truss suitable for large-span floors according to claim 1, characterized in that: The guide rail (14) has several independent guide grooves, and each guide groove is equipped with a steel cable (11).

10. The suspended truss suitable for large-span floors according to claim 1, characterized in that: Both the crossbeam (1) and the arch beam (2) are steel pipe truss structures.
