Description

Technical Field

[0001] The invention relates to the technical field of column pile construction, in particular to a vertical positioning device for temporary column piles in a foundation pit. Background Art

[0002] Foundation pit construction is a systematic project that integrates geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. It mainly includes engineering survey, support structure design and construction, earth excavation and backfilling, groundwater control, information construction and surrounding environmental protection. The function of the column pile is to support the side wall of the foundation pit, withstand the soil pressure from the surrounding foundation pit, prevent the foundation pit from deformation and collapse, and ensure the stability of the foundation pit during excavation.

[0003] Patent announcement number CN214530695U discloses a positioning frame for steel columns and steel cages of foundation pit retaining structure columns, including a rectangular outer frame formed by steel outer beams; two longitudinal steel inner beams are welded inside the rectangular outer frame, and two transverse steel inner beams are welded between the two longitudinal steel inner beams, and the above four steel inner beams constitute a rectangular inner frame; the rectangular outer frame is placed on the foundation surface, and the rectangular inner frame is placed on the top ring surface of the steel casing of the column pile hole; a vertical centerline column is welded in the middle section of each steel outer beam; the rectangular outer frame is provided with a pin hole, and the pin hole is provided with an anchor bar inserted into the foundation; and it also includes two vertically symmetrical straightening assemblies and two left-right symmetrical straightening assemblies. It can ensure the verticality and centering of the steel column part and the steel cage part when inserting, and avoid eccentric load of the column pile.

[0004] When the above positioning frame is in use, the purpose of tightening the steel cage or steel column is achieved by using a compression spring and a compression roller. Although the compression spring has the function of automatic inward compensation from the steel cage to the column pile under the elastic force of the compression spring itself, the allowed movement distance under the elastic force will also cause the column pile or the steel cage to deviate. The compensation distance may cause the overall positioning device to not deviate, and then the verticality calibration may not be accurate enough. Therefore, a vertical positioning device for temporary column piles in foundation pits is proposed to solve the above problem. Summary of the invention

[0005] In order to solve the above-mentioned problems, the present invention provides a vertical positioning device for temporary column piles in a foundation pit.

When performing the work of vertically positioning the column pile body 1, the frame plate 2 is sleeved on the outside of the column pile body 1. During this period, after respectively rotating the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38, the movement of the second trapezoidal plates 36 can be controlled to extrude and push the first trapezoidal plate 35, and finally the first pressure rollers 31 and the second pressure rollers 32 are moved to be in contact with the outside of the column pile body 1. By performing fitting and extrusion in this way, the tightness after fitting can be ensured, and the problem that the frame plate 2 tilts due to insufficient fitting force and the verticality calibration is not accurate enough can be avoided, improving the stability and accuracy during the construction process.

[0032] The first bidirectional threaded rod 37 is arranged on the top of the second bidirectional threaded rod 38. Two first threaded blocks 39 are arranged on the outside of the first bidirectional threaded rod 37. The first threaded blocks 39 are slidably connected to the inner side of the frame plate 2.

One ends of the two first push rods 391 are respectively movably connected to the two second trapezoidal plates 36 on one side of the first pressure rollers 31 through movable hinge seats. The thread directions at both ends of the first bidirectional threaded rod 37 are opposite. When rotating in different directions, the two first threaded blocks 39 outside can be driven to move in opposite or away directions, and then the first push rods 391 are caused to swing in different directions; There are two second threaded blocks 392 arranged outside the second bidirectional threaded rod 38.

The second bidirectional threaded rod 38 sequentially penetrates through the two second threaded blocks 392, and the second bidirectional threaded rod 38 is threadedly connected to the second threaded blocks 392. Both of the two second threaded blocks 392 are movably connected with second push rods 393 through movable hinge seats. One ends of the two second push rods 393 are respectively movably connected with two second trapezoidal plates 36 on one side of the second pressure roller 32 through movable hinge seats. The thread directions at both ends of the second bidirectional threaded rod 38 are opposite. When rotating in different directions, it can drive the two second threaded blocks 392 outside to move in opposite or away directions, thereby causing the second push rods 393 to swing in different directions; Both the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38 extend outside the frame plate 2. One ends of the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38 are both fixedly connected with a rotating plate 394. Two rectangular frames 395 are fixedly connected to the outside of the frame plate 2. The two rectangular frames 395 are respectively arranged on the tops of the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38. Inside the two rectangular frames 395, there are extrusion plates 396 slidably connected. The two extrusion plates 396 respectively extend outside the two rectangular frames 395. The two extrusion plates 396 are respectively in contact with the outside of the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38. The user controls the rotation of the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38 respectively by controlling the rotation of the rotating plate 394. After the extrusion plates 396 are in contact with the outside of the first bidirectional threaded rod 37 and the second bidirectional threaded rod 38, they can respectively perform frictional limiting on the two to prevent them from rotating by themselves. The top of the extrusion plate 396 is rotatably connected with a threaded adjustment rod 397. The threaded adjustment rod 397 extends outside the rectangular frame 395 and is threadedly connected to the rectangular frame 395. After the threaded adjustment rod 397 rotates, it drives the extrusion plate 396 to move up and down. A connection frame 398 is fixedly connected to the inner wall of the frame plate 2.

[0033] There are four platform plates 4 arranged on the outer side of the frame plate 2. The four platform plates 4 are symmetrically distributed in a rectangular shape at the central positions around the frame plate 2. An auxiliary component 5 is arranged on the platform plate 4. The auxiliary component 5 includes an auxiliary frame 51. The auxiliary frame 51 is arranged on one side of the platform plate 4. A cross plate 52 is arranged on one side of the auxiliary frame 51. The auxiliary frame 51 and the cross plate 52 are connected by a rotating shaft. A cross groove 53 is opened on the platform plate 4. The cross groove 53 matches the auxiliary frame 51 and the cross plate 52 respectively. A limit telescopic rod and a spring 54 are fixedly connected to the outer side of the frame plate 2. The spring 54 is arranged outside the limit telescopic rod. Both the spring 54 and the limit telescopic rod penetrate through the platform plate 4. One ends of the spring 54 and the limit telescopic rod are fixedly connected to one side of the auxiliary frame 51. The auxiliary frame 51 and the cross plate 52 can enter the inside of the cross groove 53 for storage. When the cross plate 52 moves to the outside of the cross groove 53, it can swing around the rotating shaft according to the change of the verticality. Two clamping grooves 55 are opened on the platform plate 4. The clamping grooves 55 communicate with the cross groove 53. A clamping block 56 is slidably connected inside the auxiliary frame 51. The clamping block 56 extends outside the auxiliary frame 51. The clamping block 56 matches the clamping groove 55. A reed 57 is fixedly connected inside the auxiliary frame 51. The reed 57 is fixedly connected to the clamping block 56. The elastic force of the reed 57 can push the clamping block 56 out of the outside of the auxiliary frame 51. An arc-shaped scale plate 58 is arranged on one side of the platform plate 4. The arc-shaped scale plate 58 is arranged at the bottom of the cross plate 52. A support rod 59 is fixedly connected between the arc-shaped scale plate 58 and the platform plate 4. Scales are arranged on the arc-shaped scale plate 58, which can form a scale indication effect on the swinging radian of the cross plate 52. The support rod 59 provides support for the arc-shaped scale plate 58.

[0034] Four anchor rods 6 are arranged at the bottom of the frame plate 2. The four anchor rods 6 are respectively fixedly connected to the four corners at the bottom of the frame plate 2. Four center line rods 7 are fixedly connected to the top of the frame plate 2. The four center line rods 7 are symmetrically distributed in a rectangular shape at the central positions around the top of the frame plate 2. A handle 8 is fixedly connected to the outer side of the frame plate 2. The anchor rods 6 are used to be inserted into the foundation to ensure the overall stability of the frame plate 2. When the user calibrates the overall verticality of the frame plate 2 in the XY two directions, the center line rods 7 can provide a measurement reference.

[0035] During the actual operation process, when this device is in use, during the construction process, the frame plate 2 is sleeved outside the column pile body 1. Subsequently, the first double-headed threaded rod 37 and the second double-headed threaded rod 38 are rotated respectively. After the first double-headed threaded rod 37 and the second double-headed threaded rod 38 are rotated, they drive the first threaded block 39 and the second threaded block 392 to move on their outer sides respectively. After the first threaded block 39 and the second threaded block 392 move, they drive the first push rod 391 and the second push rod 393 to flip and swing respectively. After the first push rod 391 and the second push rod 393 swing, they drive the two second trapezoidal plates 36 to move respectively. After the second trapezoidal plate 36 moves, it contacts the inclined surface on one side of the first trapezoidal plate 35 to form an extrusion and pushing effect. At this time, the first trapezoidal plate 35 drives the auxiliary plate 34 to move, the auxiliary plate 34 drives the connecting plate 33 to move, and the connecting plate 33 drives the first pressure roller 31 and the second pressure roller 32 to move respectively, so that the first pressure roller 31 and the second pressure roller 32 are attached to the outside of the column pile body 1, thereby completing the stable installation of the frame plate 2 outside the column pile body 1; After the above frame plate 2 is installed, due to the relatively complex and changeable construction site environment, in order to avoid the situation that the external factors cause the rotation plate 394 to be accidentally touched and rotated, which in turn causes the connection between the frame plate 2 and the column pile body 1 to become unstable, rotate the threaded adjusting rod 397, and the threaded adjusting rod 397 drives the pressing plate 396 to move. After the two pressing plates 396 are respectively tightly attached to the outside of the first double-headed threaded rod 37 and the second double-headed threaded rod 38 in this way, the first double-headed threaded rod 37 and the second double-headed threaded rod 38 can be frictionally limited, so as to ensure the stability of the first double-headed threaded rod 37 and the second double-headed threaded rod 38; The cross plate 52 and the auxiliary frame 51 are connected by a rotating shaft, so the cross plate 52 can swing around the rotating shaft following the verticality of the frame plate 2 and the column pile body 1. During the swinging period, by the different scales indicated by the bottom end of the cross plate 52 on the arc scale plate 58, the staff can intuitively understand the verticality of the frame plate 2. During the idle use period, in order to avoid the situation that the cross plate 52 is directly exposed outside and may be damaged due to collisions and other factors, the cross plate 52 can also be stored. Specifically, when storing, press the cross plate 52 into the cross groove 53, and during this period, push the two clamping blocks 56 into the auxiliary frame 51. When the cross plate 52 enters the cross groove 53 and the clamping blocks 56 are at the corresponding positions of the clamping grooves 55, stop pressing the clamping blocks 56. At this time, the reed 57 pushes the clamping blocks 56 into the clamping grooves 55. Through the above connection relationship, it can be seen that at this time, the cross plate 52 and the auxiliary frame 51 stay inside the cross groove 53. By performing flexible storage in this way, the flexibility of the device during use is effectively guaranteed and its service life is extended.

[0036] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
