Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a wall positioning device for assembling prefabricated culvert covers. Background Technology

[0002] A slab culvert consists of a culvert body made up of a slab cover, abutment cap, culvert platform, foundation, and expansion joints. The fill height ranges from 1 to 8 meters, and can even reach 12 meters. When the culvert diameter is large and the embankment is high, the slab culvert is more expensive than an arch culvert, but the construction technology is simpler and the flood discharge capacity is greater.

[0003] With the continuous updating of prefabricated building construction technology and the continuous improvement of technical level, the requirements for building functions are constantly increasing. This places higher demands on the dimensional and appearance quality of prefabricated building components. However, when positioning the existing prefabricated culvert walls, the assembly relies entirely on the experience of technicians, resulting in a series of problems such as low installation efficiency and low positioning accuracy, which causes great trouble for subsequent construction.

[0004] Therefore, it is necessary to provide a new wall positioning device for assembling prefabricated culvert covers to solve the above-mentioned technical problems. Utility Model Content

The positioning plate is welded and fixed to the surface of the base plate. The limiting rod slides inside the top of the positioning plate. The screw is threaded to the center position of the top of the positioning plate. The positioning frame is installed on the side wall of the top of the screw. A limiting structure is provided, with both ends of the limiting structure fixedly connected to the base plate. The limiting structure includes a fixing block, a lead screw, a fixing platform, and a limiting platform. The fixing block is fixed to the side wall of one end of the base plate. Both ends of the lead screw are threaded to the fixing block. The fixing platform is installed on the side walls of both ends of the lead screw. The limiting platform is fixed to the surface of the fixing platform.

[0007] Preferably, the base structure further includes a limiting frame, a baffle, and a groove. The groove is located on the side wall at the center of the base plate. The limiting frame is welded and fixed to the surface of the base plate at the edge of the groove. The baffle is welded and fixed to the side wall at one end of the limiting frame.

[0008] Preferably, the shape of the limiting frame corresponds to the shape of the groove, one end is open, and the inner sidewall of the limiting frame is flush with the sidewall of the groove.

[0009] Preferably, one sidewall of the limiting frame is close to the positioning plate, and the shape of the positioning frame is the same as the shape and inner space of the limiting block, and the positioning frame, the limiting block and the groove are on the same center line.

[0010] Preferably, the lead screw is threadedly connected to the fixing block, and the fixing platform slides on the side wall of the lead screw. The edge of the positioning platform surface is also provided with a through hole, and the through hole intersects with the channel through which the lead screw passes.

[0011] Preferably, the limiting platform is provided in two sets, and every two limiting platforms form a group, and the two limiting platforms in each group are in a phase shape, and the top surface of the limiting platform is inclined, and the distance between the two opposing limiting platforms is equal to the length of the internal space of the groove.

[0013] Compared with related technologies, the prefabricated culvert assembly wall positioning device provided by this utility model has the following advantages:

[0014] This utility model provides a positioning device for the vertical wall of a prefabricated culvert. First, the positioning device is placed according to the location of the vertical wall to be installed. Then, based on the dimensions of the vertical wall, the position of the limiting platform in the limiting structure is adjusted so that the distance between two sets of limiting platforms in the same row is less than the length of the vertical wall. Next, the platform is fixed to the ground with fixing nails, thus fixing the position of the limiting platform. Then, the vertical wall is hoisted to the limiting platform, allowing it to be accurately placed in the designated position guided by the inclined surface of the limiting platform. Simultaneously, the limiting platform provides initial positional restriction for the vertical wall. Finally, by rotating the lead screw, the two ends of the limiting structure can be driven... The fixed base structure moves towards the center, simultaneously driving the positioning structure to move synchronously. This allows the base structure to engage with the side wall of the upright wall via the limiting frame and the groove. The positioning frame of the lifting structure also engages with the side wall of the upright wall, preventing the upright wall from moving left or right. The base plate is then fixed to the ground with fixing nails. The height of the positioning frame is adjusted to be more than half the height of the upright wall by rotating the screw. The length of the support rod is adjusted, and then bolts are used to fix both ends of the support rod to the side wall of the positioning frame and the surface of the base plate, respectively. This allows the support rod to support the upright wall through the positioning frame, ensuring the stability of the upright wall and facilitating subsequent assembly. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 , Figure 1 A schematic diagram of a preferred embodiment of the prefabricated culvert assembly wall positioning device provided by this utility model; Figure 2 for Figure 1 The diagram shows a three-dimensional view of the positioning structure from the side. Figure 3 for Figure 2 A schematic diagram of the cross-section of the positioning structure shown; Figure 4 for Figure 1 A schematic diagram of the cross-section of the limiting structure shown; Figure 5 for Figure 1 The top view of the base structure shown in the diagram illustrates the prefabricated culvert assembly wall positioning device, which includes: a support rod 1; a base structure 2, one end of the support rod 1 being bolted to both ends of the surface of the base structure 2, the base structure 2 including a base plate 21, one end of the support rod 1 being bolted to both ends of the surface of the base plate 21, and the two ends of the surface of the base plate 21 respectively having screw holes and through holes, and the base plate 21 being fixed to the ground by fixing nails 5 through the through holes; and a positioning structure 3, fixed to the surface of the base plate 21, the positioning structure 3 including a positioning plate 31, a limiting rod 32, a positioning frame 33, and a screw 34, the positioning plate 31 being welded and fixed. On the surface of the base plate 21, the limiting rod 32 slides inside the top end of the positioning plate 31, the screw 34 is threadedly connected to the center position of the top end of the positioning plate 31, and the positioning frame 33 is installed on the side wall of the top end of the screw 34; the limiting structure 4 has its two ends fixedly connected to the base plate 21, and the limiting structure 4 includes a fixing block 41, a lead screw 42, a fixing platform 43, and a limiting platform 44. The fixing block 41 is fixed to the side wall of one end of the base plate 21, the two ends of the lead screw 42 are threadedly connected to the fixing block 41, the fixing platform 43 is installed on the side walls of both ends of the lead screw 42, and the limiting platform 44 is fixed to the surface of the fixing platform 43.

[0023] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 5As shown, the base structure 2 further includes a limiting frame 22, a baffle 23, and a groove 24. The groove 24 is located on the side wall of the base plate 21 at its center. The limiting frame 22 is welded and fixed to the surface of the base plate 21 along the edge of the groove 24. The baffle 23 is welded and fixed to the side wall of one end of the limiting frame 22. The shape of the limiting frame 22 corresponds to the shape of the groove 24, with one end being open. The inner side wall of the limiting frame 22 is flush with the side wall of the groove 24. One side wall of the limiting frame 22 is close to the positioning plate 31. The shape and inner space of the positioning frame 33 are the same as those of the limiting block. The positioning frame 33, the limiting block, and the groove 24 are on the same center line. This allows the positioning frame 33, the limiting frame 22, and the groove 24 to restrict the position of the wall, enabling the two side walls of the wall to engage with the inside of the limiting frame 22 and the positioning frame 33.

[0024] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 5 As shown, the lead screw 42 is threadedly connected to the fixing block 41, and the fixing platform 43 slides on the side wall of the lead screw 42. The edge of the positioning platform 43 surface is also provided with a through hole, and the through hole intersects with the channel through which the lead screw 42 passes. There are two sets of limiting platforms 44, and each set of two limiting platforms 44 is a group. The two limiting platforms 44 in each group are in a phase shape, and the top surface of the limiting platform 44 is inclined. The distance between the two opposing limiting platforms 44 is equal to the length of the internal space of the groove 24. First, the position of the fixing platform 43 can be adjusted by sliding it on the lead screw 42. Then, the position of the limiting platform 44 can be adjusted by the fixing platform 43, so that the hoisting of the precast wall can be guided by the inclined surface of the limiting platform 44, so that the wall can be accurately erected at the installation location.

[0025] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 5 As shown, the other end of the support rod 1 is fixed to the side wall of one end of the positioning frame 33 by bolts, and the two ends of the support rod 1 are rotatably connected to the positioning frame 33 and the base plate 21 respectively. The support rod 1 is telescopic, which facilitates the support of the positioning frame 33 by the support rod 1, thereby stabilizing the position of the wall.

[0026] The working principle of the prefabricated culvert assembly wall positioning device provided by this utility model is as follows:

[0027] In use, first place the base plate 21 at the installation position of the culvert wall, adjust the position of the device so that the two sets of limiting structures 4 are at the two ends of the installation position, and the limiting platform 44 abuts against the ground through the fixing platform 43. The fixing platform 43 is fixed to the ground by the fixing nails 5. Then, the prefabricated culvert wall is hoisted to the device, so that the bottom end of the prefabricated culvert wall is placed between the two sets of limiting structures 4 by the guide of the limiting platform 44. The side wall restricts the position of the wall. Then, by rotating the screw 42, it is threaded to rotate with the fixing block 41. The fixing block 41 then pulls the base towards the center, which drives the positioning frame 33 and the limiting frame 22 to fit onto the side walls at both ends of the wall. Then, the fixing nail 5 fixes the base plate 21 to the ground, further restricting the position of the wall. Then, by rotating the screw 34, under the restriction of the limiting rod 32, the positioning frame 33 rises with the rotation of the screw 34, raising the positioning frame 33 to half the height of the wall. Then, the two ends of the support rod 1 are fixed between the base plate 21 and the positioning frame 33 with bolts, so that the support rod 1 further supports the wall through the positioning frame 33, making the wall assembly more stable.

[0028] Compared with related technologies, the prefabricated culvert assembly wall positioning device provided by this utility model has the following advantages:

[0029] This utility model provides a positioning device for the vertical wall of a prefabricated culvert assembly. First, the positioning device is placed according to the location of the vertical wall to be installed. Then, based on the dimensions of the vertical wall, the position of the limiting platform 44 in the limiting structure 4 is adjusted so that the distance between two sets of limiting platforms 44 in the same row is less than the length of the vertical wall. Next, the fixing platform 43 is fixed to the ground with fixing nails 5, thus fixing the position of the limiting platform 44. Then, the vertical wall is hoisted to the limiting platform 44, allowing it to be accurately placed in the designated position guided by the inclined surface of the limiting platform 44. Simultaneously, the limiting platform 44 provides initial positional restriction for the vertical wall. Finally, by rotating the lead screw 42, the two ends of the limiting structure 4 can be fixed. The base structure 2 moves towards the center, simultaneously driving the positioning structure 3 to move synchronously. This allows the base structure 2 to engage with the side wall of the upright wall via the limiting frame 22 and the groove 24. The positioning frame 33 of the lifting structure also engages with the side wall of the upright wall, preventing the upright wall from moving left or right. The base plate 21 is then fixed to the ground with fixing nails 5. The height of the positioning frame 33 is adjusted to be more than half the height of the upright wall by rotating the screw 34. The length of the support rod 1 is adjusted, and then bolts are used to fix both ends of the support rod 1 to the side wall of the positioning frame 33 and the surface of the base plate 21, respectively. This allows the support rod 1 to support the upright wall via the positioning frame 33, ensuring the stability of the upright wall and facilitating subsequent assembly.
