Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, specifically to PC hollow prefabricated retaining walls. Background Technology

[0002] A retaining wall is a structure that supports roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. In the cross-section of a retaining wall, the part that is in direct contact with the supported soil is called the back of the wall, the part opposite the back of the wall and exposed to the air is called the front of the wall, the part that is in direct contact with the foundation is called the base, the part opposite the base and the top of the wall is called the top of the wall, the front end of the base is called the toe of the wall, and the rear end of the base is called the heel of the wall.

[0003] Currently, most hollow prefabricated retaining walls cannot be adjusted for wall panels of different sizes during use; they can only be installed with wall panels of a single size, which is inconvenient for daily use. Furthermore, most retaining walls do not have a device to limit the support frame during use, which makes the support frame prone to unfolding during transportation, further hindering transport. To address these issues, the inventors have proposed a PC hollow prefabricated retaining wall to solve these problems. Utility Model Content

[0004] To address the issues of not being able to install wall panels of different sizes and the ease with which the support frame can unfold during transportation, the purpose of this utility model is to provide a PC hollow prefabricated retaining wall.

A fixing block is fixedly mounted on the bottom of the side of the vertical plate, and a limit rod is slidably mounted inside the fixing block. A spring is fixedly mounted on the side of the fixing block away from the support plate, and the end of the spring away from the fixing block is fixedly connected to the handle of the limit rod. One end of the limit rod is movably inserted into the support plate.

[0006] Preferably, the side of the vertical plate away from the wall panel is movably inserted into the insert rod, and the end of the insert rod near the wall panel movably passes through the limiting block and is movably inserted into the wall panel, and the insert rod and the vertical plate are rotatably engaged.

[0007] Preferably, a limiting plate is slidably installed on the upper surface of the vertical plate, and the lower surface of the limiting plate is in movable contact with the upper surface of the wall panel.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a PC hollow prefabricated retaining wall, including a base plate 1, with movable plates 11 slidably installed on both sides of the base plate 1. A vertical plate 2 is detachably installed on the upper surface of the movable plate 11, and a wall panel 21 is detachably installed between the vertical plates 2. A movable seat 3 is slidably installed on the side of the vertical plate 2 for installing a support plate 31. The support plate 31 is rotatably installed in the movable seat 3, and the bottom end of the support plate 31 is in contact with the ground. A fixing block 27 is fixedly installed at the bottom of the side of the vertical plate 2, and a limiting rod 28 is slidably installed in the fixing block 27 to limit the support plate 31 and prevent the support plate 31 from unfolding during transportation. One end of the limiting rod 28 is movably inserted into the support plate 31.

[0020] Slide rails 12 are fixedly installed on both sides of the movable plate 11, and the slide rails 12 are slidably disposed inside the base plate 1. A bidirectional screw 13 is rotatably installed inside the base plate 1, and the movable plate 11 is threadedly connected to the bidirectional screw 13 to drive the movable plate 11 to move. In use, the movable plate 11 is driven to move by the rotation of the bidirectional screw 13.

[0021] By adopting the above technical solution, the bidirectional screw 13 can drive the moving plate 11 to move.

[0022] A rotating rod 15 is rotatably mounted on the side of the base plate 1. A second bevel gear 16 is fixedly mounted on one end of the rotating rod 15 near the bidirectional screw 13. A first bevel gear 14 is fixedly mounted on the outer surface of the bidirectional screw 13, and the first bevel gear 14 and the second bevel gear 16 mesh with each other to drive the bidirectional screw 13 to rotate. In use, rotating the rotating rod 15 drives the second bevel gear 16 to rotate, which in turn drives the first bevel gear 14 to rotate, and the rotation of the first bevel gear 14 drives the bidirectional screw 13 to rotate.

[0023] By adopting the above technical solution, the rotating rod 15 can drive the bidirectional screw 13 to rotate.

[0024] A spring 29 is fixedly installed on the side of the fixed block 27 away from the support plate 31, and the end of the spring 29 away from the fixed block 27 is fixedly connected to the handle of the limiting rod 28 to drive the limiting rod 28 to move. When in use, the limiting rod 28 is pulled outward to disengage the limiting rod 28 from the inside of the support plate 31. At this time, the spring 29 deforms. When the hand is released, the spring 29 releases the deformation force and drives the limiting rod 28 to move inward.

[0025] By adopting the above technical solution, the spring 29 can drive the limit rod 28 to move.

[0026] A limiting block 32 is fixedly installed on the side of the movable seat 3, and the limiting block 32 is slidably disposed inside the vertical plate 2 to limit the movable seat 3. A sliding groove is opened in the vertical plate 2, and the limiting block 32 slides up and down inside the sliding groove, so that the movable seat 3 can only move along the sliding groove.

[0027] By adopting the above technical solution, the limiting block 32 can limit the movement of the movable seat 3.

[0028] The side of the vertical plate 2 away from the wall plate 21 is movably inserted into the insertion rod 26. The end of the insertion rod 26 near the wall plate 21 movably passes through the limiting block 32 and is movably inserted into the wall plate 21. The insertion rod 26 and the vertical plate 2 are rotated and engaged to limit the movement of the movable seat 3. When in use, when the insertion rod 26 is inserted, the movable seat 3 cannot move, thus limiting the movement of the movable seat 3.

[0029] By adopting the above technical solution, the insertion rod 26 can limit the movement of the movable seat 3.

[0030] A limiting plate 23 is slidably installed on the upper surface of the vertical plate 2, and the lower surface of the limiting plate 23 is in contact with the upper surface of the wall panel 21. A slider 24 is fixedly installed on the lower surface of the limiting plate 23, and the slider 24 is slidably disposed inside the vertical plate 2. A screw rod 25 is rotatably installed on the side of the vertical plate 2, and the slider 24 is threadedly connected to the screw rod 25 to limit the wall panel 21. In use, rotating the screw rod 25 drives the slider 24 to move, and the movement of the slider 24 drives the limiting plate 23 to move, so that the lower surface of the limiting plate 23 and the upper surface of the wall panel 21 come into contact, thereby limiting the wall panel 21.

[0031] By adopting the above technical solution, the limiting plate 23 can limit the wall panel 21.

[0032] An installation block 22 is fixedly installed on the lower surface of the vertical plate 2, and the installation block 22 is movably inserted into the inside of the movable plate 11. A locking screw 17 is threadedly connected to the side of the movable plate 11, and the installation block 22 is threadedly connected to the locking screw 17 for installing the vertical plate 2. In use, the installation block 22 is inserted into the inside of the movable plate 11, and the locking screw 17 is screwed in to limit the installation block 22, thus completing the installation of the vertical plate 2.

[0033] By adopting the above technical solution, the locking screw 17 can limit the vertical plate 2.

[0034] Working principle: First, insert the mounting block 22 into the moving plate 11, screw in the locking screw 17 to limit the mounting block 22, and complete the installation of the vertical plate 2;

[0035] Next, rotating the rotating rod 15 drives the second bevel gear 16 to rotate, which in turn drives the first bevel gear 14 to rotate, which in turn drives the double-headed screw 13 to rotate, which in turn drives the moving plate 11 to move, which in turn drives the vertical plate 2 to move, thereby adjusting the distance between the vertical plates 2 to facilitate the installation of wall panels 21 of different sizes. Then, the wall panels 21 are inserted between the vertical plates 2.

[0036] Then rotate the screw rod 25 to drive the slider 24 to move. The movement of the slider 24 drives the limit plate 23 to move, so that the lower surface of the limit plate 23 and the upper surface of the wall panel 21 are in contact, thus limiting the wall panel 21.

[0037] Finally, pull the limiting rod 28 outward to disengage it from the support plate 31. At this point, the support plate 31 can move. Then, pull out the insertion rod 26. At this point, the movable seat 3 can move. Move the movable seat 3 to the lowest end, insert the insertion rod 26 to limit the movable seat 3, fix the position of the movable seat 3, and rotate the support plate 31 so that the bottom end of the support plate 31 contacts the ground to support the vertical plate 2.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
