[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] See Figures 1 to 4 This utility model provides a pile cap 1 removal device, wherein the pile cap 1 has a vertically penetrating opening 2, the opening 2 having a length direction and a width direction, and the removal device includes:

[0024] The bracket body 3 is inserted into the opening 2 in the vertical direction, and forms an upper support part 301 and a lower support part 302 exposed at the upper and lower ends of the opening 2. The upper support part 301 is provided with a plurality of lifting points 4 for installing lifting equipment.

[0025] The stop bar structure includes at least one first stop bar 5 and at least one second stop bar 6, the first stop bar 5 and the second stop bar 6 are respectively arranged along the length direction and the width direction, and both are detachably connected to the lower support part 302 for abutting against the outer area of ​​the opening 2;

[0026] The lengths of the upper support 301 and the lower support 302 are defined as L1 and L2, respectively, and the diagonal length of the opening 2 is L3, satisfying L1 > L3 and L2 < L3, and the length of L1 extends outward from the length of the pile cap by not less than 10cm.

[0027] In this embodiment, the demolition device includes a bracket main body 3. The bracket main body 3 is inserted into the opening 2 of the pile cap 1 in the vertical direction. An upper support portion 301 and a lower support portion 302 are respectively formed at the upper and lower parts of the bracket main body 3. The upper support portion 301 and the lower support portion 302 are respectively exposed from above and below the opening 2. Four jacking points 4 are provided on the upper support portion 301. The jacking points 4 are used for the jacking part of the jacking equipment, such as a hydraulic jack, etc., to provide an upward thrust to help separate the pile cap 1 from the precast square pile. A stop bar structure is provided on the lower support portion 302. The stop bar structure includes a first stop bar 5 and a second stop bar 6. The first stop bar 5 and the second stop bar 6 are respectively arranged along the length direction and the width direction of the opening 2 of the pile cap 1, and both the first stop bar 5 and the second stop bar 6 are detachably connected to the lower support portion 302, which is convenient for adjusting the position and quick installation and demolition. The main functions of the first stop bar 5 and the second stop bar 6 are to abut against the outer area of the opening 2 of the pile cap 1 during the demolition process to ensure the stability during the demolition process and prevent accidental sliding or tilting. At the same time, to ensure the effectiveness and safety of the demolition device, the length of the upper support portion 301 is greater than the diagonal length of the opening 2 (L1 > L3), and L1 extends out of the outer edge in the length direction of the pile cap by not less than 10 cm to ensure a sufficient support area. The length of the lower support portion 302 is less than the diagonal length of the opening 2 (L2 < L3). Not less than 10 cm is reserved outside the reinforcing rib as the jacking point and the length of L1 is clearly defined and it extends out of the outer edge in the length direction of the pile cap by not less than 10 cm so that the lower support portion 302 can be smoothly inserted into the opening 2. That is, when the lower support plate of the bracket main body 3 is inserted into the opening 2, it is inserted along the diagonal of the opening 2, and then the angle of the lower support portion 302 is adjusted so that it neatly abuts against the left and right ends of the opening 2. At the same time, since the length L1 of the upper support portion 301 extends out of the outer edge in the length direction of the pile cap by not less than 10 cm and not less than 10 cm is reserved outside the reinforcing rib as the jacking point, after using the jacking equipment to jack the jacking point 4, the pile cap 1 is subjected to a vertically upward force, and the pile cap 1 can be quickly separated from the precast square pile.

[0028] The bracket main body 3 further includes a plurality of vertical rods 7 arranged at intervals, which are used to connect the upper support portion 301 and the lower support portion 302.

[0029] In this embodiment, a plurality of connection points are formed between the upper support portion 301 and the lower support portion 302 by the plurality of vertical rods 7, which increases the rigidity and stability of the entire bracket main body 3, helps to provide a more uniform support force distribution during the jacking operation process, and reduces the risk of structural deformation.

[0030] A plurality of cross rods 8 are provided between adjacent two of the vertical rods 7, and both ends of the cross rod 8 are respectively fixedly connected to the corresponding two vertical rods 7.

[0031] In this embodiment, the crossbar 8 forms a horizontal support between adjacent vertical bars 7, which significantly enhances the deformation resistance of the entire support body 3. The support body 3 can withstand greater loads during the lifting operation without twisting or bending.

[0032] The upper support portion 301 is connected to at least one of the vertical rods 7 and the lower support portion 302 is connected to at least one of the vertical rods 7 by reinforcing ribs 9.

[0033] In this embodiment, the reinforcing rib 9 can better distribute and transmit the force applied to the support body 3, making the support body 3 more uniform and stable when bearing load. Due to the presence of the reinforcing rib 9, the support body 3 can withstand greater lifting force. Especially during the dismantling process, when a large upward or downward force is required to separate the pile cap 1, the reinforcing rib 9 can ensure that the structure will not be damaged due to overload.

[0034] The upper support portion 301, the vertical rod 7, and the reinforcing rib 9 form a first reinforcing cavity 10 with a triangular cross-section, and the reinforcing rib 9 is the hypotenuse of the first reinforcing cavity 10; the lower support portion 302, the vertical rod 7, and the reinforcing rib 9 form a second reinforcing cavity with a triangular cross-section, and the reinforcing rib 9 is the hypotenuse of the second reinforcing cavity (not shown).

[0035] In this embodiment, the first reinforced cavity 10, which is a triangle formed by the upper support 301, the vertical rod 7, and the reinforcing rib 9, with the reinforcing rib 9 as the hypotenuse, ensures the stability of the jacking equipment installation position and maintains stability even under high-load operating conditions. The lower support 302, the vertical rod 7, and the reinforcing rib 9 can also form a second reinforced cavity (not shown) in a triangle, with the reinforcing rib 9 as the hypotenuse as well. This not only enhances the rigidity of the overall structure but also improves the stability of the support body 3 when it is inserted into the opening 2 of the pile cap 1. The design of the triangular reinforced cavity significantly improves the load-bearing capacity and compressive strength of the entire device. In particular, during the jacking operation, it can withstand greater vertical forces, ensuring the safety and efficiency of the construction process.

[0036] The lower support 302 is provided with a plurality of first positioning holes 11 at intervals along the length direction, and the first stop 5 is provided with a plurality of second positioning holes 12 at intervals along the length direction, for the locking bolts 13 to pass through and for fixing the lower support 302 and the first stop 5 relative to each other.

[0037] In this embodiment, the lower support 302 has four first positioning holes 11 along its length, allowing the length of the first stop 5 to be adjusted according to actual conditions to achieve the best support effect. The first stop 5 also has four second positioning holes 12 along its length, with each second positioning hole 12 corresponding to one of the first positioning holes 11 on the lower support 302, facilitating fixation with locking bolts 13. This allows the first stop 5 to be locked in different positions, adapting to openings 2 of different sizes and shapes. Similarly, the second stop 6 can also have its length adjusted by setting the first positioning holes 12 and second positioning holes 11, as well as the first stop 5, according to different sizes of pile cap openings 2.

[0038] The second stop 6 is provided with a latch 601 for engaging with the lower support portion 302. Furthermore, the lower support portion 302 is provided with an upward-opening notch 303, and the latch 601 opens downwards to engage with the notch 303, so that the upper surfaces of the first stop 5 and the second stop 6 are on the same plane.

[0039] In this embodiment, one end of the second stop 6 is used to engage with the lower support 302. The lower support 302 has a corresponding notch 303 for engaging with the latch 601 on the second stop 6, ensuring that the latch 601 is firmly engaged with the lower support 302 and preventing loosening or detachment due to external forces. The latch 601 design makes the installation and removal of the second stop 6 simpler and faster. Construction personnel only need to align the latch 601 with the corresponding position 303 of the notch on the lower support 302 and gently push it in to complete the installation. The second stop 6 can be flexibly adjusted in position and angle according to actual needs to better adapt to different shapes and sizes of pile cap 1 openings 2, improving the versatility and applicability of the equipment. Through the engagement of the notch 303 and the latch 601, the upper surfaces of the first stop 5 and the second stop 6 are ensured to be on the same plane, which is particularly important for applications requiring precise contact with the outer area of ​​the pile cap 1 opening 2. Consistent upper surfaces help improve construction accuracy and avoid construction problems caused by unevenness. When the upper surfaces of the first stop 5 and the second stop 6 are on the same plane, the force applied to them can be transmitted more evenly to the entire support body 3, reducing local stress concentration, which not only improves the safety of the equipment, but also extends its service life.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
