Description

Technical Field

[0001] This utility model is a rebar cage locator for cast-in-place piles, belonging to the field of building construction. Background Technology

[0002] During construction, the traditional method used to correct the displacement of the reinforcing cage is the "lifting method." First, in the early stages of construction, appropriate reinforcing hoops need to be placed at the top of the bridge pile foundation. Second, external force is needed to correct the position of the displaced portion of the reinforcing cage. The force required is quite precise; excessive force can cause deformation of the reinforcing bars, thus affecting the overall structure of the reinforcing cage.

[0003] Therefore, in the patent application number 202122139814.1 for an adjustable positioner for a bored pile reinforcement cage, when the offset part of the reinforcement cage needs to be corrected, the worm at the corresponding position of the adjustable positioner is rotated. The rotation of the worm drives the worm wheel to rotate. Since the worm wheel and the screw are connected by a threaded transmission, the screw moves horizontally, pushing the fixed clamp to move inward. When the fixed clamp moves, it is guided by the guide rod sliding in the support. Since the fixed clamp has a circular arc structure, it is pressed against the reinforcement cage. Since the transmission mechanism of the worm wheel and worm has a self-locking characteristic, that is, after the worm stops rotating, the worm wheel will not rotate again, thus achieving the purpose of locking after the fixed clamp moves into place.

[0004] As described in the aforementioned patent, the offset portion of the reinforcing cage is corrected by moving the circular arc-shaped fixing clamp. It also describes rotating the worm gear at the corresponding adjustable locator. In other words, the adjustable locator at the corresponding position is in a fixed position. If the offset portion of the reinforcing cage does not perfectly align with the locator at that position, additional locators are needed, thus increasing the number of reinforcing cage locators. Furthermore, the fixed-position locator cannot perform the correction work for the corresponding reinforcing cage, resulting in the problem of multiple locators. Therefore, this utility model proposes a grouting pile reinforcing cage locator that facilitates adjustment of the locator position to better correct the offset portion of the reinforcing cage. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rebar cage positioner for cast-in-place piles.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A rebar cage locator for cast-in-place piles includes a fixed base set on the top of the pile. A locator is installed on the fixed base. The locator includes a locating component and an mounting component connecting the locating component. The mounting component includes a U-shaped mounting seat, which is installed on the fixed base. Threaded locating holes are evenly arranged at equal intervals on the fixed base. The U-shaped mounting seat has two corresponding secondary threaded locating holes. A threaded rod is inserted into both the secondary threaded locating holes and the threaded locating holes, and a nut is fitted onto the threaded rod. The locating component has an arc-shaped locating plate.

[0007] Furthermore, the positioning component includes a vertical mounting plate, a through groove on the U-shaped mounting base for the vertical mounting plate to pass through, and threaded mounting holes on both the vertical mounting plate and the outer wall of the U-shaped mounting base.

[0008] Furthermore, the vertical mounting plate has multiple threaded mounting holes, which are evenly spaced. The threaded mounting holes on the U-shaped mounting base are set in two groups, and the number of threaded mounting holes in each group is the same, and there are multiple holes.

[0009] Furthermore, a forward plate is fixedly installed at the top of the vertical mounting plate, and a threaded rod is threaded onto the forward plate. A manual turntable is fixedly installed at one end of the threaded rod, and a cylinder is rotatably connected to the other end of the threaded rod. The cylinder is fixedly connected to the positioning plate through a gasket.

[0010] Furthermore, the threaded rod is divided into a threaded mounting part and a fixing part. One end of the fixing part is fixedly provided with a mounting plate, and multiple fixing plates arranged in a circle are fixedly provided on the mounting plate. The end of the threaded mounting part is provided with a through groove for the fixing plates to pass through, and the fixing plates are fixed in the through groove with screws.

[0011] Furthermore, the other end of the fixing part is T-shaped, and a T-shaped rotating groove is provided inside the cylinder, with the T-shaped end of the fixing part rotatably set in the T-shaped rotating groove.

[0012] Furthermore, a telescopic assembly is provided between the forward plate and the positioning plate. The telescopic assembly includes a telescopic rod and mounting plates fixed to both ends of the telescopic rod. The mounting plates are fixed to the forward plate and the positioning plate with screws.

[0013] Furthermore, secondary positioning plates are installed at both the top and bottom of the positioning plate. The secondary positioning plates and the positioning plate are connected to each other by insert plates and fixed with screws.

[0014] The beneficial effects of this utility model are: With the fixed platform in place, the rebar cage is located within the platform. A detachable locator is installed on the platform, primarily via a U-shaped mounting base. The U-shaped mounting base has secondary threaded positioning holes, and similarly spaced threaded positioning holes are also present on the fixed platform. To correct the required position, the secondary threaded positioning holes on the U-shaped mounting base are aligned with the corresponding threaded positioning holes. Combined with the installation of rods and nuts, the positioning plate on the mounting component is fixed after displacement. In other words, the displaced locator better corresponds to the offset position of the rebar cage. If the position is not corrected, additional locators are needed, without increasing the number of rebar cage locators required. Furthermore, depending on the actual situation, an appropriate number of detachable locators can be installed on the fixed platform for better correction of the offset portion of the rebar cage.

[0015] The positioning plate, which is movable, is pressed against the rebar cage to correct any offset parts of the rebar cage. This invention is simple to set up. With simple installation and the addition of an appropriate number of positioning devices, it can better correct the offset parts of the rebar cage, thus improving the overall practicality and convenience.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a rebar cage locator for cast-in-place piles, including a fixed base 1, which is set on the top of the pile. A locator 2 is installed on the fixed base 1. The locator 2 includes a locating component and an installation component 3 that connects to the locating component. The installation component 3 includes a U-shaped mounting seat 4, which is installed on the fixed base 1. Threaded locating holes 5 are evenly arranged at equal intervals on the fixed base 1. The U-shaped mounting seat 4 has two secondary threaded locating holes 6 corresponding to the threaded locating holes 5. A screw 7 passes through the secondary threaded locating holes 6 and the threaded locating holes 5, and a nut is matched on the screw 7. The locating component has an arc-shaped locating plate 8.

[0021] See Figure 1-2 The positioning component includes a vertical mounting plate 9 and a U-shaped mounting base 4 with a through groove 10 for the vertical mounting plate 9 to pass through. Threaded mounting holes 11 are provided on both the vertical mounting plate 9 and the outer wall of the U-shaped mounting base 4. The vertical mounting plate 9 has multiple threaded mounting holes 11, which are evenly spaced. The U-shaped mounting base 4 has two groups of threaded mounting holes 11, with each group having the same number of holes. The vertical mounting plate 9 has a through groove 10 and is also equipped with a screw. After the vertical mounting plate 9 is manually moved in height, the threaded mounting holes 11 on the vertical mounting plate 9 and the U-shaped mounting base 4 align. The screw is inserted to fix the manually moved vertical mounting plate 9, thus adjusting its height. This also allows the positioning plate 8 to adjust its height, improving ease of use. The height adjustment of the positioning plate 8 better corresponds to the position that needs correction.

[0022] See Figure 1 and Figure 3A forward plate 12 is fixedly mounted on the top of a vertical mounting plate 9. A threaded rod 13 is threaded onto the forward plate 12. A manual turntable 14 is fixedly mounted on one end of the threaded rod 13, and a cylinder 15 is rotatably connected to the other end of the threaded rod 13. The cylinder 15 is fixedly connected to the positioning plate 8 via a gasket. The threaded rod 13 is divided into a threaded mounting part 16 and a fixing part 17. A mounting plate 18 is fixedly mounted on one end of the fixing part 17. Multiple fixing pieces 24 arranged in a circle are fixed on the mounting plate 18. The end of the threaded mounting part 16 is provided with a through groove 25 for the fixing pieces 24 to pass through. The fixing pieces 24 are fixed in the through groove 25 with screws. The other end of the fixing part 17 is T-shaped. A T-shaped rotating groove 19 is opened inside the cylinder 15. The T-shaped end of the fixing part 17 is rotatably mounted in the T-shaped rotating groove 19. The manual turntable 14 is manually rotated to drive the threaded rod 13. 3. The rotational forward movement causes the rotating cylinder 15 to move forward, and the cylinder 15 is connected to the positioning plate 8, thus causing the positioning plate 8 to move forward, completing the corresponding position correction work. The threaded rod 13 is divided into a threaded mounting part 16 and a fixing part 17. The fixing plate 24 of the mounting plate 18 is inserted into the through groove 25 and fixed with screws. Therefore, the threaded mounting part 16 and the fixing part 17 are detachable. The threaded mounting part 16 and the fixing part 17 can be detached and separated, so that a longer threaded mounting part 16 can be replaced. The threaded mounting part 16 and the means turntable are integrated. Replacing the threaded mounting part 16 with a longer threaded mounting part 16 can drive the positioning plate 8 to be adjusted to a farther position, which can better correct the position according to the needs of different sized steel cages. When the threaded rod 13 rotates, the T-shaped part 17 rotates in the T-shaped rotating groove 19 of the cylinder 15, thus causing the cylinder 15 to move.

[0023] See Figure 3 A telescopic assembly is provided between the forward plate 12 and the positioning plate 8. The telescopic assembly includes a telescopic rod 20 and mounting plates 21 fixed at both ends of the telescopic rod 20. The mounting plates 21 are fixed to the forward plate 12 and the positioning plate 8 with screws. The telescopic rod 20 is provided with mounting plates at both ends and fixed with screws. Therefore, the telescopic rod can be detached and installed and can be replaced when damaged. The telescopic rod is a telescopic rod and is a publicly available component. It will not be described in detail here. The design function of the telescopic rod 20 is to ensure that the positioning plate 8 can move horizontally.

[0024] See Figure 4 The top and bottom of the positioning plate 8 are equipped with secondary positioning plates 22. The secondary positioning plates 22 and the positioning plate 8 are connected to each other by insert plates 23 and fixed with screws. The secondary positioning plates 22 are installed according to the actual situation. The number of secondary positioning plates 22 installed is appropriate. The overall correction area is increased by adding positioning plates 8 and secondary positioning plates 22. Therefore, the offset area of ​​the steel cage is different. Thus, the addition of secondary positioning plates 22 to positioning plates 8 can better complete the correction work.

[0025] In use, the rebar cage is positioned within the fixed base 1. A detachable locator 2 is installed on the fixed base 1. The locator 2 is primarily installed via a U-shaped mounting base 4. The U-shaped mounting base 4 has a secondary threaded positioning hole 6, and threaded positioning holes 5 are evenly spaced on the fixed base 1. To adjust the position as needed, the secondary threaded positioning hole 6 on the U-shaped mounting base 4 is aligned with the corresponding threaded positioning hole 5. Then, with the installation of the screw 7 and nut, the positioning plate 8 on the mounting component 3 is fixed after displacement. In other words, the displaced locator can better correspond to the offset position of the rebar cage. If the position is not corrected, additional locators are needed, without increasing the number of rebar cage locators. Furthermore, a suitable number of locators can be detachably installed on the fixed base 1 according to the actual situation to better correct the offset portion of the rebar cage. The positioning plate 8 is movable and is pressed against the rebar cage to correct the offset portion of the rebar cage. This utility model is simple to set up. With simple installation and the addition of an appropriate number of positioning devices, it can better correct the offset portion of the rebar cage and improve the overall practicality and convenience.
