[0025] See Figure 1 - Figure 2 As shown, the long-span composite steel support structure described in this embodiment includes a support platform 1 and a plurality of support members 2. The support platform 1 is formed by splicing a plurality of support plates 3. A plurality of mounting seats 11 are provided on the support platform 1. A plurality of the support members 2 are screwed and installed on the mounting seats 11 through bolt structures, and a plurality of the support members 2 are distributed in a staggered manner on the support platform 1.

[0026] The structure of this embodiment is simple and reasonably designed. By providing a plurality of support members 2 and distributing them in a staggered manner, a more stable support effect can be achieved. At the same time, after the support platform 1 is assembled, the support members 2 can be installed, without overall machining, and the processing and installation are more flexible and convenient. Specifically, this embodiment is equivalent to a modular setting and can be pre-assembled, thus facilitating construction.

[0027] Specifically, the support platform 1 and the support member 2 in this embodiment are both supported by H400×400×13×21 steel to ensure the support strength.

[0028] In some embodiments, brackets 4 are hingedly provided on opposite sides of the bottom end of the support member 2, and one end of the bracket 4 away from the support member 2 is fixedly connected to the mounting seat 11.

[0029] In this embodiment, by providing the bracket 4 and connecting it to the support platform 1, it can cooperate with the support member 2 to form a triangular support area, thereby effectively improving the support strength.

[0030] In some embodiments, the top end of the support member 2 has a connecting piece 5. The center of the connecting piece 5 has a cavity and is filled with an elastic structure 6.

[0031] Specifically, the four sides of the connecting piece 5 extend beyond the top edge of the support member 2.

[0032] Specifically, a plurality of the cavities are provided at intervals.

[0033] In this embodiment, by providing the connecting piece 5, it is convenient to connect with the bridge deck to be supported. The elastic structure 6 provided on the connecting piece 5 can provide shock absorption, thereby ensuring the stability of the connection and achieving a better support effect.

[0034] In some embodiments, as shown in Figure 2 the adjacent support plates 3 are respectively provided with matching splicing parts 31.

[0035] Specifically, the splicing part 31 is provided with a screw hole 32 and a welding area 33.

[0036] In this embodiment, it is specifically shown that after the support plates 3 are spliced, they are then screwed and welded to form a stable support platform 1, which has a simple structure and good stability.

[0037] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
