Description

Technical Field

[0001] This invention relates to the field of interlocking cast-in-place pile reinforcement cage docking technology, specifically to an interlocking cast-in-place pile reinforcement cage docking guide structure. Background Technology

[0002] Interlocking cast-in-place piles are a type of foundation pit retaining structure formed by the interlocking of adjacent concrete piles. They consist of alternating ultra-slow-setting plain concrete piles (A piles) and reinforced concrete piles (B piles), and are constructed using a full-casing drilling rig. Their core feature is that they achieve continuous soil retention and water stoppage through the interlocking of the piles. They are suitable for deep foundation pit projects with high groundwater levels and narrow sites. During the pouring of B piles, a reinforcing cage must be placed before pouring can proceed.

[0003] Existing technologies lack a guiding structure for the docking of reinforcing cages within cast-in-place piles. This means that during the docking and lowering process, existing reinforcing cages often require lifting equipment to hoist the upper cage, followed by manual movement to dock the main reinforcement bars of the upper cage with those of the lower cage. Furthermore, manual maintenance of the docking posture is necessary after docking, which not only hinders rapid docking guidance but also fails to automatically maintain the docking posture for easy connection of the upper and lower cages. Based on the shortcomings of existing technologies, this invention designs a docking guiding structure for interlocking cast-in-place pile reinforcing cages. Summary of the Invention

The locking bolt is threaded into the second threaded cylinder. The positioning rod is inserted into the limiting sleeve. The guide arm is fixedly connected to the inner end of the positioning rod. The upper guide arc plate is fixedly connected to the top end of the guide arm. The lower docking arc plate is fixedly connected to the bottom end of the guide arm.

[0006] As a preferred embodiment of the present invention, the adjustment mechanism includes a slide rail, a slide table, a pulley, a first threaded cylinder, and a positioning bolt.

[0007] As a preferred embodiment of the present invention, the support mechanism includes a rotating frame, a socket, a locking pin, a first support arm, an arc-shaped locking plate, a rotating shaft, and a support. The rotating frame is fixedly connected to the side wall of the guide cover, the socket is opened through the side wall of the rotating frame, the locking pin is inserted into the socket, the top end of the first support arm is rotatably connected to the rotating frame, the arc-shaped locking plate is fixedly connected to the top end of the first support arm, the rotating shaft is fixedly connected to the bottom end of the first support arm, and the support is rotatably connected to the rotating shaft.

[0008] As a preferred embodiment of the present invention, a connecting piece is fixedly connected between the upper and lower reinforcing cages.

[0009] As a preferred embodiment of the present invention, the inner side of the upper guide arc plate is in contact with the main reinforcement of the upper steel cage, and the inner side of the lower connecting arc plate is in contact with the main reinforcement of the lower steel cage.

[0010] As a preferred embodiment of the present invention, the positioning rod is provided with scale lines, and the bottom end of the locking bolt passes through the limiting sleeve and contacts the positioning rod.

[0011] As a preferred embodiment of the present invention, the inner end of the locking rod passes through the lifting seat and is inserted into the lock hole, and the second support arm is fixedly connected to the outside of the slide table.

[0012] As a preferred embodiment of the present invention, the pulley is slidably connected to the slide rail, and the positioning bolt is inserted through and connected to the slide table and the second support arm.

[0013] In a preferred embodiment of the present invention, the inner end of the slide table is in contact with the outer wall of the slide rail.

[0014] As a preferred embodiment of the present invention, the arc-shaped locking plate is rotatably disposed within the rotating frame, and the locking pin is inserted through the arc-shaped locking plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The interlocking guide structure for the reinforcing cage of the cast-in-place pile involves fixing the lower reinforcing cage (which is not fully inserted into the pile hole) after it is in place. A guide cover is then fitted around the outer ring of the lower reinforcing cage, and a support is placed on the ground. The first arm provides support for the guide cover. If the height of the guide cover and the interlocking guide mechanism is too low or too high, the locking pin needs to be pulled out of the arc-shaped locking plate to release it. Then, the first arm is rotated clockwise or counterclockwise to adjust its support height for the guide cover. After the height of the guide cover and the interlocking guide mechanism is adjusted, the locking pin is reinserted into the insertion hole and the arc-shaped locking plate to lock the first arm. This device facilitates support for the guide cover and the interlocking guide mechanism and allows for adjustment of the interlocking guide mechanism's height.

[0016] 2. The interlocking cast-in-place pile reinforcement cage docking guide structure, after the guide cover is supported and fixed, loosens the positioning bolts to release the lock between the slide table and the slide rail. Then, under the limit of the slide rail and pulley, the slide table moves left or right, driving the docking guide mechanism to move accordingly, so that the lower docking arc plate moves to align with the main reinforcement of the lower reinforcement cage. Then, the positioning bolts are tightened to lock the position of the slide table and the docking guide mechanism. At this time, the locking bolts are loosened to lock the positioning rod. Then, the positioning rod is slowly pushed inward through the guide arm to make the lower docking arc plate contact the lower reinforcement cage for positioning and tightening. Tighten the locking bolts to lock the position of the positioning rod and the lower connecting arc plate. Then, follow the same steps to position the lower connecting arc plates of the remaining groups. At this time, the upper steel cage is lifted by the hoisting equipment and moved vertically downward. During the downward movement, the upper steel cage is manually rotated to allow the main bars of the upper steel cage to slowly insert into the inner side of the upper guide arc plate. The upper guide arc plate and the lower connecting arc plate are used to limit the positioning of the upper and lower steel cages and guide the connection. Finally, the upper and lower steel cages are connected using the connecting parts. This device facilitates the guidance of the connection between the upper and lower steel cages.

The second threaded cylinder 507 is fixedly connected to the side wall of the limiting sleeve 506. Bolt 508 is threaded into the second threaded sleeve 507. Positioning rod 509 is inserted into the limiting sleeve 506. Guide arm 510 is fixedly connected to the inner end of positioning rod 509. Upper guide arc plate 511 is fixedly connected to the top of guide arm 510. Lower connecting arc plate 512 is fixedly connected to the bottom of guide arm 510. The inner side of upper guide arc plate 511 is in contact with the main reinforcement of upper steel cage 1.

[0022] By setting up a guide arm 510, an upper guide arc plate 511, and a lower connecting arc plate 512, the lower connecting arc plate 512 is positioned after it is in contact with the main reinforcement of the lower steel cage 102. The upper guide arc plate 511 is used to guide the connection of the main reinforcement of the upper steel cage 1. By setting up a limiting sleeve 506, a second threaded sleeve 507, a locking bolt 508, and a positioning rod 509, the positions of the lower connecting arc plate 512 and the upper guide arc plate 511 can be adjusted and locked according to the different diameters of the upper steel cage 1 and the lower steel cage 102. By setting up a second support arm 501, a lifting groove 502, a lifting seat 503, a locking hole 504, and a locking rod 505, the working height of the upper guide arc plate 511 and the lower connecting arc plate 512 can be finely adjusted, so that the lower connecting arc plate 512 and the upper guide arc plate 511 are not too high or too low and cannot contact the main reinforcement of the upper steel cage 1 or the connecting piece 101.

[0023] Please see Figure 5The adjusting mechanism 4 includes a slide rail 401, a slide table 402, a pulley 403, a first threaded cylinder 404, and a positioning bolt 405.

The positioning bolt 405 is inserted through the slide table 402 and the second support arm 501. The inner end of the slide table 402 is in contact with the outer wall of the slide rail 401.

[0024] By setting up slide rail 401, slide table 402 and pulley 403, the position of docking guide mechanism 5 can be adjusted so that the upper guide arc plate 511 and lower docking arc plate 512 can move along the slide rail 401 path to adjust their position to align with the main bars of the upper steel cage 1 and lower steel cage 102. By setting up first threaded cylinder 404 and positioning bolt 405, the position of slide table 402 and docking guide mechanism 5 can be locked.

[0025] Please see Figure 4 The support mechanism 3 includes a rotating frame 301, an insertion hole 302, a locking pin 303, a first support arm 304, an arc-shaped locking plate 305, a rotating shaft 306, and a support 307. The rotating frame 301 is fixedly connected to the side wall of the guide cover 2. The insertion hole 302 is opened through the side wall of the rotating frame 301. The locking pin 303 is inserted into the insertion hole 302. The top end of the first support arm 304 is rotatably connected to the rotating frame 301. The arc-shaped locking plate 305 is fixedly connected to the top end of the first support arm 304. The rotating shaft 306 is fixedly connected to the bottom end of the first support arm 304. The support 307 is rotatably connected to the rotating shaft 306. The arc-shaped locking plate 305 is rotatably arranged in the rotating frame 301, and the locking pin 303 is inserted through the arc-shaped locking plate 305.

[0026] By setting up a rotating frame 301, a first support arm 304, a rotating shaft 306, and a support 307, support is provided for the guide cover 2 and the adjustment mechanism 4 and docking guide mechanism 5 connected to the guide cover 2, thereby improving the stability of the guide cover 2, the adjustment mechanism 4, and the docking guide mechanism 5 during docking guidance. By setting up a socket 302, a locking pin 303, and an arc-shaped locking plate 305, the support angle of the first support arm 304 can be adjusted, thereby adjusting the working height of the guide cover 2, the adjustment mechanism 4, and the docking guide mechanism 5.

[0027] Working principle: When the interlocking cast-in-place pile reinforcement cage docking guide structure is used, in the initial state, the lower reinforcement cage 102 is first placed below the upper reinforcement cage 1. The upper reinforcement cage 1 and the lower reinforcement cage 102 are connected by the docking piece 101. A guide cover 2 is set on the outside of the upper reinforcement cage 1 and the lower reinforcement cage 102. The rotating frame 301 installed on the guide cover 2 is rotatably connected to the first support arm 304, the rotating shaft 306 and the support 307. The arc-shaped locking plate 305 fixedly connected to the top of the first support arm 304 is also rotatably connected in the rotating frame 301 and is limited by the insertion of the locking pin 303, so as to provide support for the guide cover 2 and improve its position. The stability of the upper steel cage 1 and the lower steel cage 102 during docking guidance is achieved by sliding a slide table 402 and a pulley 403 on the slide rail 401 on the outer surface of the guide cover 2. The second support arm 501 connected to the slide table 402 is slidably connected to a lifting seat 503, a limiting sleeve 506 and a positioning rod 509, which are limited by a locking rod 505 and a locking hole 504. A guide arm 510 is provided at the inner end of the positioning rod 509. The upper and lower ends of the guide arm 510 are respectively provided with an upper guide arc plate 511 and a lower docking arc plate 512 to facilitate the docking guidance of the main reinforcement bars of the upper steel cage 1 and the lower steel cage 102. When it is necessary to support the guide cover 2 and the docking guide mechanism 5 and adjust the working height of the docking guide mechanism 5, first, after the lower steel cage 102, which is not fully inserted into the grouting pile hole, is fixed, the guide cover 2 is fitted onto the outer ring of the lower steel cage 102, and the support 307 is placed on the ground. The first support arm 304 provides support for the guide cover 2. If the working height of the guide cover 2 and the docking guide mechanism 5 is too low or too high, the locking pin 303 needs to be pulled out from the arc-shaped locking plate 305 to release the locking of the locking pin 303. Then, the first support arm 304 is rotated clockwise or counterclockwise to adjust the support height of the first support arm 304 for the guide cover 2. After the working height of the guide cover 2 and the docking guide mechanism 5 is adjusted, the locking pin 303 is reinserted into the insertion hole 302 and the arc-shaped locking plate 305 to lock the first support arm 304. This device facilitates the support of the guide cover 2 and the docking guide mechanism 5 and the adjustment of the working height of the docking guide mechanism 5.

[0028] When it is necessary to guide the connection between the upper rebar cage 1 and the lower rebar cage 102, first, after the guide cover 2 is fixed, tighten the positioning bolt 405 to release the lock between the slide table 402 and the slide rail 401. Then, under the limit of the slide rail 401 and the pulley 403, move the slide table 402 to the left or right and drive the connection guide mechanism 5 to move accordingly, so that the lower connection arc plate 512 moves to align with the main reinforcement of the lower rebar cage 102. Then, tighten the positioning bolt 405 to lock the position of the slide table 402 and the connection guide mechanism 5. At this time, loosen the locking bolt 508 to lock the positioning rod 509. Then, slowly push the positioning rod 509 inward through the guide arm 510 to make the lower connection arc plate 512 align with the lower rebar cage 102. The two phases are contacted for positioning and the locking bolts 508 are tightened to lock the position of the positioning rod 509 and the lower connecting arc plate 512. Then, the lower connecting arc plates 512 of the remaining groups are positioned according to the same steps. At this time, the upper steel cage 1 is lifted by the hoisting equipment and moved vertically downward. During the downward movement, the upper steel cage 1 is manually rotated to slowly insert the main bars of the upper steel cage 1 into the inner side of the upper guide arc plate 511. The upper guide arc plate 511 and the lower connecting arc plate 512 are used to limit the connection and guide the connection of the upper steel cage 1 and the lower steel cage 102. Finally, the upper steel cage 1 and the lower steel cage 102 are connected by the connecting piece 101. This device facilitates the connection of the upper steel cage 1 and the lower steel cage 102.
