DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0033] Reference Figures 1 to 4 The embodiment of the present application discloses a reinforced bridge frame 100, including a bottom plate 1 and two side plates 2, wherein the bottom plate 1 and the side plates 2 are formed by integrally bending sheet metal, and a first reinforcing rib 3 is also formed at the bending portion of the bottom plate 1 and the side plates 2, a second reinforcing rib 11 is formed on the bottom plate 1, and a third reinforcing rib 21 is formed on the side plates 2, and both the second reinforcing rib 11 and the third reinforcing rib 21 are connected to the first reinforcing rib 3.

[0034] In this embodiment, the first reinforcing ribs 3, the second reinforcing ribs 11 and the third reinforcing ribs 21 are provided in a plurality and arranged in an array along the length direction of the bridge 100. The sizes of the first reinforcing ribs 3, the second reinforcing ribs 11 and the third reinforcing ribs 21 and the spacing of the array need to be adjusted according to the actual size of the bridge 100.

[0035] Reference Figure 2 and Figure 4, the first reinforcing rib 3 is in an arc shape and extends a certain distance along the length direction of the bridge frame 100. Properly lengthening the length of the first reinforcing rib 3 can increase the effect of the first reinforcing rib 3. The second reinforcing rib 11 and the third reinforcing rib 21 have the same shape, forming a symmetrical structure, which has a beautiful appearance and a more balanced reinforcement effect. Specifically, the second reinforcing rib 11 and the third reinforcing rib 21 are both in a trapezoidal shape. The closer the second reinforcing rib 11 is to the bend of the bottom plate 1 and the side plate 2, the greater the depth is, which has a transition effect, is easier to process, and is not easy to wrinkle.

[0036] The present application has a first reinforcing rib 3 formed at the bending part of the bottom plate 1 and the side plate 2, a second reinforcing rib 11 formed on the bottom plate 1, and a third reinforcing rib 21 formed on the side plate 2. The second reinforcing rib 11 and the third reinforcing rib 21 are both connected to the first reinforcing rib 3 to form a combined reinforcing rib, which can significantly increase the strength of the bending part of the bottom plate 1 and the side plate 2; and the depths of the first reinforcing rib 3, the second reinforcing rib 11 and the third reinforcing rib 21 can be designed to be shallower to avoid excessive wrinkling or even rupture of the reinforcing ribs at the bending part of the bottom plate 1 and the side plate 2 due to stretching.

[0037] Reference Figure 8 and Fig. 9 A flared opening 4 is also provided at the end of one end of the bridge frame, which is used for plugging and splicing two adjacent bridge frames 100 to extend each other. In this way, a connecting plate is no longer required between the bridge frames 100, which can reduce the number of parts and reduce costs.

[0038] Reference Figure 8 The side plate 2 at the flared opening 4 is provided with a first connection hole 22, and the side plate 2 at the other end of the bridge frame 100 opposite to the flared opening 4 is correspondingly provided with a second connection hole 23. The two bridge frames 100 spliced ​​to each other are connected and fixed by fasteners provided at the first connection hole 22 and the second connection hole 23. One of the first connection hole 22 and the second connection hole 23 is a horizontal waist-shaped hole, and the other is a vertical waist-shaped hole, so that the two bridge frames 100 can be fine-tuned in length and height, which is more convenient for on-site assembly. After adjustment, they are locked with fasteners.

[0039] Reference Figure 2 and Figure 4 The bottom plate 1 is also provided with a fourth reinforcing rib 12 for enhancing the strength of the bottom plate 1, and the side plate 2 is also provided with a fifth reinforcing rib 24 for enhancing the strength of the side plate 2, which belongs to the content of the prior art and will not be repeated here.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
