High-performance prefabricated composite beams have the advantages of both steel bridges and concrete bridges. They use high-performance materials to achieve lightweight, and change reinforced concrete connections to mechanical connections to achieve assembly without on-site wet operations. The lightweight components facilitate water and land transportation. Assembly greatly speeds up bridge construction, reduces interference with urban traffic, construction pollution, and noise nuisance, and solves the problems of traditional prefabricated assembled beams, such as large volume, difficult transportation, and the need for special equipment for erection.

[0006] Furthermore, fixing nuts are arranged on both sides of the supporting pier, and the fasteners are fixing studs, which pass through the diagonal bracing rods and are threadedly connected with the fixing nuts, and the protrusions on the fixing studs abut against the diagonal bracing rods.

[0007] Furthermore, a tightening rod is provided at the end of the fixing stud for rotating the fixing stud.

[0008] Furthermore, the fixing nut is connected to the supporting pier by welding.

[0024] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an I-shaped steel plate beam anti-dumping positioning and assembly platform, including a base 1, four pulleys 2 are arranged at the bottom of the base 1, one pulley 2 is provided at each of the four corners, and they are symmetrically arranged, and universal wheels with braking function are adopted, so that it can roll in any direction and be braked and fixed at any time.

[0025] A support pier 3 is provided at the middle position of the top of the base 1, and the support pier 3 and the base 1 are integrally cast steel components. A height adjustment support 4 is provided at the top of the support pier 3, and the I-shaped steel plate beam 17 is placed on the height adjustment support 4, and the height adjustment support 4 is used to adjust the height of the I-shaped steel plate beam 17. A first fixing nut 5 and a second fixing nut 6 are welded and fixed on both sides of the support pier 3.

[0026] A first diagonal brace 7 and a second diagonal brace 8 are respectively provided on both sides of the top of the base 1, wherein the first diagonal brace 7 is connected to the base 1 through a first hinge support 9, and the second diagonal brace 8 is connected to the base 1 through a second hinge support 10, and the first hinge support 9 and the second hinge support 10 are welded and fixed to the base 1. The first diagonal brace 7 and the second diagonal brace 8 can rotate in a vertical plane around the corresponding hinge support.

[0027] The two diagonal braces are fixed to both sides of the support pier 3 by fasteners. Figure 5 and Figure 6 The fastener of the first diagonal brace 7 is the first fixing stud 11, and the fastener of the second diagonal brace 8 is the second fixing stud 12. The first fixing stud 11 passes through the first diagonal brace 7 from the middle of the first diagonal brace 7 and is threadedly connected with the first fixing nut 5. The protrusion on the first fixing stud 11 abuts against the first diagonal brace 7. The second fixing stud 12 passes through the second diagonal brace 8 from the middle of the second diagonal brace 8 and is threadedly connected with the second fixing nut 6. The protrusion on the second fixing stud 12 abuts against the second diagonal brace 8. The free ends of the two diagonal braces support the I-shaped steel plate beam 17 on both sides of the I-shaped steel plate beam 17. In this embodiment, the free end of the first diagonal brace 7 is provided with a first anti-skid plate 15, and the free end of the second diagonal brace 8 is provided with a second anti-skid plate 16. The side of the anti-skid plate contacting the web of the I-shaped steel plate beam 17 is provided with a serrated anti-skid rubber surface, which increases the friction force while ensuring that the surface of the I-shaped steel plate beam is not worn.

[0028] A first tightening rod 13 is disposed at the end of the first fixing stud 11 , and a second tightening rod 14 is disposed at the end of the second fixing stud 12 . The tightening rod is used to manually rotate the corresponding fixing stud.

[0029] Combination Figure 3 and Figure 4 The elevation adjustment support 4 is a simple jack. Specifically, the elevation adjustment support 4 is composed of an outer shell (hidden in the figure) and an internal jack structure. The elevation adjustment support 4 is fixed to the supporting pier 3 through the studs on the chassis 41. The working principle of the internal jack structure is that the rotation of the buckle 42 drives the rotation of the small bevel gear 43 at the end, and the small bevel gear 43 drives the large bevel gear 44 to rotate (deceleration and lifting torque). Since the interior of the large bevel gear 44 is connected to the screw 45 by a spiral pair, and due to the characteristics of the spiral pair itself, the screw 45 can be lifted and lowered to achieve the effect of controlling the assembly elevation of the I-shaped steel plate beam.

[0030] The method of using the utility model is as follows:

[0031] When in use, the I-shaped steel plate beam 17 is first hoisted onto the working platform, and the I-shaped steel plate beam 17 is moved to the corresponding assembly position through each pulley 2. After the movement and positioning, each pulley 2 is braked to fix the working platform. After the position of the working platform is fixed, the assembly elevation of the I-shaped steel plate beam 17 is adjusted by the elevation adjustment support 4. After the assembly height is determined, the first diagonal brace 7 and the second diagonal brace 8 are respectively rotated so that the anti-slip plate at the free end of the first diagonal brace 7 and the second diagonal brace 8 contacts the web of the I-shaped steel plate beam 17. After the positions of the first diagonal brace 7 and the second diagonal brace 8 are determined, the ends of the first fixing stud 11 and the second fixing stud 12 are respectively aligned with the first fixing nut 5 and the second fixing nut 6 on both sides of the supporting pier 3. By rotating the first tightening rod 13 and the second tightening rod 14, the first fixing stud 11 and the second fixing stud 12 are respectively penetrated into the first fixing nut 5 and the second fixing nut 6, so as to fix the I-shaped steel plate beam 17 and prevent the I-shaped steel plate beam 17 from tipping over and shifting sideways.
