Description

Technical Field

[0001] This utility model relates to the field of building wall technology, specifically to a stable unloading platform for building walls. Background Technology

[0002] An unloading retaining wall is a retaining structure in which an unloading platform or unloading plate is installed on the back of the wall to reduce the soil pressure on the back of the wall and increase the stabilizing moment. The weight of the backfill and the weight of the wall itself jointly resist the lateral pressure of the soil. An unloading retaining wall is a common type of retaining wall. A reinforced concrete slab of a certain length is installed on the back of the wall at an appropriate height. This slab divides the soil behind the wall into two parts.

[0003] According to announcement number CN 212534202 U, a new type of prefabricated retaining wall structure for building engineering includes a wall toe, a wall panel, and a wall heel plate. The wall toe and the wall heel plate are on the same horizontal plane, and the wall panel is vertically connected to the side wall at the connection between the wall toe and the wall heel plate.

[0004] This device, a novel prefabricated retaining wall structure for construction projects, utilizes a first block whose left side wall is fixedly connected to the side wall of the wall panel via reinforcing bars. A first protrusion, matching the size of a first slot, is fixedly connected to one side wall of the second block. A second protrusion, matching the second slot, is fixedly installed on the lower side wall of the third block. The side wall of the third block in contact with the wall panel is then fixedly connected via reinforcing bars. Using this prefabricated retaining wall structure not only simplifies transportation but also simplifies assembly, saving time and effort for workers and improving work efficiency. However, the upper load on the retaining wall can easily cause it to bend, reducing its overturning resistance and making it prone to collapse. Utility Model Content

[0005] The purpose of this utility model is to provide a stable unloading platform for building walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable unloading platform for building walls, comprising a wall, a precast base plate fixedly connected to the bottom of the wall, a sliding mechanism provided on the top of the precast base plate, and a limit mechanism provided on the top of the sliding mechanism;

[0007] The sliding mechanism includes a first fixed frame, which is fixedly connected to the top of the precast base plate. Sliding rods are fixedly connected to the front and rear sides of the first fixed frame. A slider is slidably connected to the surface of the sliding rod. An unloading plate is fixedly connected to the top of the slider. A support plate is fixedly connected to the back of the top of the unloading plate. A sliding frame is symmetrically fixedly connected to the top of the precast base plate. A sliding sleeve is slidably connected to the surface of the sliding frame. A first rack is fixedly connected to the top of the sliding sleeve. A second fixed frame is symmetrically fixedly connected to the top of the precast base plate. Rotary shafts are rotatably connected to the left and right sides of the second fixed frame near the top. A gear is fixedly connected to the middle of the surface of the rotating shaft. A second rack is symmetrically fixedly connected to the bottom of the unloading plate.

[0008] Preferably, the back of the support plate is fixedly connected to the front of the wall by bolts, and the back of the unloading plate is fixedly connected to the front of the wall by bolts.

[0009] Preferably, the back of the first rack is fixedly connected to the front of the wall near the bottom, and the first rack meshes with a gear, and the second rack meshes with a gear.

[0010] Preferably, the limiting mechanism includes a box body, which is fixedly connected to the top and back of the precast slab. A sliding plate is slidably connected to the inner wall of the box body. Guide rods are symmetrically fixedly connected to the upper and lower sides of the inner wall of the box body. A spring is sleeved on the surface of the guide rod between the bottom of the inner wall of the box body and the sliding plate. An inclined block is fixedly connected to the top of the sliding plate. A third fixing frame is fixedly connected to the front of the wall.

[0011] Preferably, the top left and right sides of the skateboard have holes that match the guide rod, and the skateboard slides up and down to the surface of the guide rod through the holes.

[0012] Preferably, the bottom end of the spring is fixedly connected to the top of the inner wall of the box, and the top end of the spring is fixedly connected to the bottom of the slide plate.

[0013] Preferably, the top of the box body has a groove that matches the inclined block, and the surface of the inclined block is connected to the groove through and slides up and down.

[0014] Compared with the prior art, this utility model provides a stable unloading platform for building walls, which has the following advantages:

[0015] This unloading platform, used for stabilizing building walls, uses a sliding mechanism to fix the unloading plate, support plate, and first rack to the front of the wall. At this time, the second rack meshes with the gear. When the wall vibrates due to external factors, the wall moves slightly forward, which in turn drives the first gear to move slightly forward, thereby causing the gear to rotate. The rotation of the gear drives the second rack to move backward, which in turn drives the unloading plate to move slightly backward, thus allowing the unloading plate to apply a pushing force to the wall, further stabilizing the wall.

[0016] This unloading platform, used for stabilizing building walls, uses a limiting mechanism to fix the unloading plate to the front of the wall with bolts. The inclined block will press against the third fixing frame, and the inclined block will also be compressed. The pressure on the inclined block will cause it to move downward, which in turn will drive the sliding plate to move downward and compress the spring. After the unloading plate is fixed, the inclined block will also be completely inserted into the third fixing frame. At this time, the inclined block will move downward by the elastic force of the spring, so that the flat part of the inclined block will contact the front of the third fixing frame, thereby limiting the inclined block, and thus limiting the unloading plate, and supporting the wall.

[0026] This utility model provides the following technical solution: Example 1

[0027] Please see Figures 1-3 This utility model provides a technical solution: a stable unloading platform for a building wall 1, including a wall 1, a precast base plate 2 fixedly connected to the bottom of the wall 1, a sliding mechanism 3 provided on the top of the precast base plate 2, and a limit mechanism 4 provided on the top of the sliding mechanism 3.

[0028] The sliding mechanism 3 includes a first fixed frame 31, which is fixedly connected to the top of the precast base plate 2. Slide rods 32 are fixedly connected to the front and rear sides inside the first fixed frame 31. Slider 33 is slidably connected to the surface of slide rods 32. Unloading plate 34 is fixedly connected to the top of slider 33. Support plate 35 is fixedly connected to the top and back of unloading plate 34. Sliding frame 36 is symmetrically fixedly connected to the top of the precast base plate 2. Sliding sleeve 37 is slidably connected to the surface of sliding frame 36. First rack 38 is fixedly connected to the top of sliding sleeve 37. Second fixed frame 39 is symmetrically fixedly connected to the top of the precast base plate 2. Rotating shaft 311 is rotatably connected to the left and right sides near the top inside the second fixed frame 39. Gear 312 is fixedly connected to the middle of the surface of rotating shaft 311. Second rack 313 is symmetrically fixedly connected to the bottom of unloading plate 34.

[0029] The back of the support plate 35 is fixedly connected to the front of the wall 1 by bolts, and the back of the unloading plate 34 is fixedly connected to the front of the wall 1 by bolts.

[0030] The back of the first rack 38 is fixedly connected to the front of the wall 1 near the bottom. The first rack 38 meshes with the gear 312, and the second rack 313 meshes with the gear 312. Example 2

[0031] Please see Figures 4-5 Furthermore, based on Embodiment 1, a limiting mechanism 4 is obtained.

[0032] The limiting mechanism 4 includes a box 41, which is fixedly connected to the top and back of the precast slab. A sliding plate 42 is slidably connected to the inner wall of the box 41. Guide rods 43 are symmetrically fixedly connected to the upper and lower sides of the inner wall of the box 41. A spring 44 is sleeved between the bottom of the inner wall of the box 41 and the sliding plate 42. An inclined block 45 is fixedly connected to the top of the sliding plate 42. A third fixing frame 46 is fixedly connected to the front of the wall 1.

[0033] The top left and right sides of the slide plate 42 have holes that match the guide rod 43, and the slide plate 42 is slidably connected to the surface of the guide rod 43 through the holes.

[0034] The bottom end of the spring 44 is fixedly connected to the top of the inner wall of the box 41, and the top end of the spring 44 is fixedly connected to the bottom of the slide plate 42.

[0035] The top of the box 41 has a groove that matches the inclined block 45, and the surface of the inclined block 45 is connected to the groove by sliding up and down.

[0036] In actual operation, when this device is used, the unloading plate 34, the support plate 35 and the first rack 38 are fixed to the front of the wall 1. At this time, the second rack 313 meshes with the gear 312. When the wall 1 vibrates due to external factors, the wall 1 moves forward slightly and drives the first gear 312 to move forward slightly, thereby driving the gear 312 to rotate. The rotation of the gear 312 will drive the second rack 313 to move backward, thereby driving the unloading plate 34 to move backward slightly, so that the unloading plate 34 can apply a pushing force to the wall 1, further making the wall 1 more stable.

[0037] The unloading plate 34 is fixed to the front of the wall 1 with bolts. The inclined block 45 will press against the third fixing frame 46. At the same time, the inclined block 45 will also be compressed. The inclined block 45 will move downward under the compression force, which will drive the sliding plate 42 to move downward to compress the spring 44. After the unloading plate 34 is fixed, the inclined block 45 will also be completely inserted into the third fixing frame 46. At this time, the inclined block 45 will move downward by the elastic force of the spring 44, so that the flat part of the inclined block 45 will contact the front of the third fixing frame 46, thereby limiting the inclined block 45, and thus limiting the unloading plate 34, and supporting the wall 1.
