Description

Technical Field

[0001] The utility model relates to the technical field of beam structures, in particular to a prestressed solid-web beam structure. Background Art

[0002] A solid beam structure is a concrete bridge structure design in which stiffeners are set to increase prestress. The stiffeners are used to apply permanent prestress to form a pre-compression force in the bridge beam to offset the bending and shear stresses caused by the load.

[0003] However, the existing solid beam structure has a single structure, resulting in low overall structural strength during use, and is unable to better transfer the pressure at the center to both ends of the beam structure, reducing the stability of the beam structure. For this reason, we propose a prestressed solid beam structure to solve the existing problems. Utility Model Content

The positioning rod is clamped to the hook and inserted into the positioning hole, so that the two pairs of reinforcing ribs support the positioning rods, and the supporting force is distributed to the solid beam body.

[0009] Preferably, a rotating seat is embedded in the inner wall of the solid beam body, and one end of the screw rod is provided with a rotating ring rotatably installed inside the rotating seat. When the screw rod rotates, the rotating force acts on the rotating seat through the rotating ring.

[0010] Preferably, the outer wall of the second screw rod is provided with mounting grooves distributed in an annular array, and a latch is inserted in the mounting groove. The latch is inserted in the mounting groove, and a rotational force is applied to the second screw rod when the latch is rotated. The mounting grooves distributed in an annular array facilitate adjustment of the latch when the rotation position is limited.

[0011] Preferably, the inner walls on both sides of the solid beam body are provided with symmetrically distributed sliding grooves, and one end of the clamping plate is provided with a slider slidably mounted inside the sliding groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model improves the strength of the solid beam body by arranging a reinforcement plate at the center of the inner wall of the solid beam body, and arranging reinforcement ribs one and two at the corners of the solid beam body, the reinforcement plate and the side edges of the solid beam body, while connecting steel strands between the reinforcement ribs two. The steel strands are inclined and distributed on both sides obliquely above the lower center of the solid beam body, and are fixedly installed on the reinforcement rib one, thereby improving the overall stability of the solid beam body.

[0021] like Figure 1-Figure 4 As shown, the prestressed solid web beam structure proposed by the utility model comprises a solid web beam body 1, a mounting plate 2, a reinforcing plate 3, a steel strand 4, a reinforcing rib 2 7 and a splint 15. A reinforcing plate 3 is arranged at the center of the solid web beam body 1, and mounting plates 2 are arranged at both ends of the solid web beam body 1. A reinforcing rib 1 5 and a reinforcing rib 2 7 which are opposite to each other in an inclined plane are arranged at the connecting angle between the solid web beam body 1 and the reinforcing plate 3 and the mounting plate 2. A steel strand 4 is arranged on one side of the reinforcing rib 2 7, and hanging rings 12 are arranged at both ends of the steel strand 4. Positioning holes 13 and fixing hooks 22 are respectively opened inside and on the outer walls of the two reinforcing ribs 2 7. Symmetrically distributed splints 15 are arranged inside both ends of the solid web beam body 1, and screw holes 21 are opened inside the splints 15. Screw holes 21 are rotatably inserted inside the screw holes 21.

[0022] The reinforcing plate 3 is integrally formed with the solid beam body 1, and the mounting plate 2 is integrally formed with the solid beam body 1;

[0023] The mounting plate 2 is provided with mounting holes 8, which are arranged in two groups and are equally spaced at the front and rear ends of the mounting plate 2;

[0024] A positioning rod 14 is provided at one end of the clamping plate 15 and penetrates through the interior of the hanging ring 12 and is inserted into the interior of the positioning hole 13;

[0025] A rotating seat 17 is embedded in the inner wall of the solid web beam body 1, and a rotating ring rotatably installed inside the rotating seat 17 is provided at one end of the screw rod 19;

[0026] The outer wall of the screw rod 19 is provided with mounting grooves 20 distributed in a circular array, and the mounting grooves 20 are plugged with latch pins 11;

[0027] The inner walls of both sides of the solid beam body 1 are provided with symmetrically distributed sliding grooves 18, and one end of the clamping plate 15 is provided with a slider 16 slidably installed inside the sliding groove 18;
