[0005] Preferably, the support member includes a threaded sleeve, in which two sections of threads with opposite rotation directions are arranged, and screw one and screw two are respectively threadedly inserted at both ends of the threaded sleeve, and the ends of screw one and screw two are respectively rotatably connected with sliders, and the sliders are slidably inserted in the slide groove.

[0006] Preferably, the outer surface of the threaded sleeve is configured to be hexagonal in shape for easy twisting with a wrench.

[0007] Preferably, a through-type strip groove is provided on the side wall of the fixing plate, and a through hole is provided on the sliding block. A bolt for locking is inserted into the through hole, and the bolt passes through the strip groove.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The utility model provides a steel support structure with a long service life. The steel sheet piles in two parallel rows are supported by support members, and the length of the support members is adjustable. Compared with traditional steel bars, the support members can provide effective support. The two ends of the support members are easy to fix and disassemble and can be reused.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3 A steel support structure with a long service life includes two groups of steel sheet piles 1 arranged side by side in front and behind. The steel sheet piles 1 are arranged in a U-shape, and the two ends are bent to form hooks 4. The two adjacent steel sheet piles 1 on the left and right are engaged with each other through the hooks 4. Two fixing plates 3 are arranged on the front and rear sides of the steel sheet piles 1, and a slide groove is formed between the two fixing plates 3. A support member 2 for preventing the steel sheet piles 1 from approaching each other is arranged between the two corresponding steel sheet piles 1 in front and behind. The length of the support member 2 is adjustable, and the two ends are against the slide groove. By adjusting the length of the support member 2, the support member 2 can effectively support the two steel sheet piles 1 in front and behind. And the two ends of the support member 2 are inserted in the slide groove and blocked by the two fixing plates 3, which can prevent the support member 2 from sliding left and right.

[0016] Specifically, the support member 2 includes a threaded sleeve 21, in which two sections of threads with opposite rotation directions are arranged, and the two ends of the threaded sleeve 21 are respectively threadedly inserted with a screw rod 22 and a screw rod 23, and the ends of the screw rod 22 and the screw rod 23 are respectively rotatably connected with a slider 24, and the slider 24 is slidably inserted in the slide groove. When the threaded sleeve 21 is rotated, the screw rod 22 and the screw rod 23 extend out or retract from the threaded sleeve 21, thereby realizing the length adjustment of the support member 2.

[0017] Furthermore, the outer surface of the threaded sleeve 21 is configured to be hexagonal in shape for easy twisting with a wrench, and the threaded sleeve 21 is rotated by twisting with a wrench.

[0018] A through-type strip groove is provided on the side wall of the fixing plate 3, and a through hole is provided on the slider 24. A bolt for locking is inserted in the through hole, and the bolt passes through the strip groove. The slider 24 is locked in a certain position in the slide groove by the bolt, thereby achieving the fixation of the slider 24, so that the two ends of the support member 2 can be well fixed and convenient for subsequent disassembly.

[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
