[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] The utility model embodiment discloses a device for fixing a retaining plate and a pile of a pile-plate type retaining wall.
[0022] Reference Figure 1-2A device for fixing a retaining plate and a pile of a pile-plate retaining wall comprises a retaining plate 1 and a pile body 2. The retaining plate 1 is arranged on the upper side of the pile body 2. A screw 3 is fixedly arranged inside the pile body 2. The upper end of the screw 3 extends to the upper side of the retaining plate 1. A nut 4 is threadedly sleeved on the upper end of the screw 3. The outer wall of the nut 4 is provided with anti-slip patterns to increase the friction between the hand and the nut 4 and prevent slipping during rotation as much as possible. A steel pad 5 is abutted against the lower side of the nut 4. The steel pad 5 is in conflict with the upper surface of the retaining plate 1. Blocks 6 are fixedly arranged on both sides of the lower surface of the steel pad 5. A slot is provided on the upper surface of the retaining plate 1 and at a position corresponding to the block 6. The block 6 is engaged with the slot.
[0023] Reference Figure 1-2 There are cavities on both sides of the interior of the nut 4, and a limit mechanism for limiting the rotation of the nut 4 is arranged inside the cavity. The limit mechanism includes a baffle 8 and a limit rod 7. The two baffles 8 are slidably arranged inside the corresponding cavities, and the two limit rods 7 are fixedly sleeved in the middle of the corresponding baffles 8. Both ends of the limit rod 7 extend to the outside of the cavity. Limit grooves are arranged on both sides of the upper surface of the steel pad 5, and the lower ends of the two limit rods 7 are plugged into the corresponding limit grooves. A pull ring 10 is movably sleeved on the top of the screw rod 3, and the upper ends of the two limit rods 7 are fixedly connected to the pull ring 10, which is convenient for pulling the two limit rods 7.
[0024] Reference Figure 1-2 The rod walls of the two limit rods 7 are movably sleeved with springs 9, and the two ends of the spring 9 are fixedly connected to the upper surface of the corresponding baffle 8 and the inner wall of the cavity, respectively, so that the baffle 8 can drive the limit rod 7 to reset. The cross-sections of the baffle 8 and the cavity are both rectangular, so that the baffle 8 can slide stably.
[0025] In the utility model, when in use, since the screw rod 3 is buried on the pile body 2, the retaining plate 1 is fixed by the nut 4 in cooperation with the screw rod 3 when the retaining plate 1 is installed, which can effectively reduce the safety hazard caused by the failure to follow up the backfill of the wall in time. Since the block 6 at the bottom of the steel pad 5 is engaged with the slot on the upper surface of the retaining plate 1, the steel pad 5 cannot rotate relative to the retaining plate 1. At the same time, in a natural state, the elastic force of the spring 9 drives the limit rod 7 to be inserted into the corresponding limit hole, so that the nut 4 cannot rotate relative to the steel pad 5, that is, it can effectively prevent the nut 4 from loosening.
[0026] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
