Description

TECHNICAL FIELD

[0001] The application relates to the technical field of static load test of pile uplift resistance, and in particular to an anchor cage connected to an anchor device for single-pile vertical uplift static load test for engineering detection. BACKGROUND

[0002] During construction of a building foundation, a detection device is needed to perform single-pile vertical uplift static load test on the foundation pile to detect the uplift resistance of the pile, so as to facilitate the stability of the building foundation.

[0003] A detection device for single-pile vertical uplift static load test is disclosed in the prior art, which comprises a support frame, a support beam, an anchor cage, a connecting frame, a hydraulic jack and a dial gauge. The support beam is erected above the measured pile by the support frame, and the connecting frame is sleeved on the support beam. The dial gauge head abuts against the upper end wall of the measured pile to detect whether the measured pile moves upward. The anchor cage is located below the support beam and is fixedly connected with the connecting frame. The hydraulic jack is located inside the support frame and is fixedly connected with the upper surface of the support beam. During detection, the reinforcement of the measured pile is fixed with the anchor cage, and then the hydraulic jack is started to push the connecting frame upward, so that the anchor cage can be driven to move upward to make the measured pile bear upward force. The pushing force of the hydraulic jack is continuously increased, and when the dial gauge head jumps, it indicates that the pile moves upward. At this time, the pushing force of the hydraulic jack is the uplift resistance of the pile. The uplift performance of the measured pile can be judged by the value of the uplift resistance.

[0004] In the related technical implementation, a connecting rib needs to be welded to the upper end of each reinforcement of the measured pile in the field in sequence, and then the upper end of the connecting rib is welded with the anchor cage to fix the anchor cage with the connecting rib of the pile. However, during welding operation, in order to ensure the welding strength, the connecting rib needs to be welded at each position along the circumferential direction of the connecting rib, which is relatively cumbersome to operate, and needs to be improved. SUMMARY

[0005] The application aims to provide an anchor cage connected to an anchor device for single-pile vertical uplift static load test for engineering detection to improve the problem of cumbersome operation of connecting the anchor cage with the pile reinforcement.

[0006] The anchor cage connected to an anchor device for single-pile vertical uplift static load test for engineering detection provided by the application adopts the following technical solution:

[0007] The utility model provides a single pile vertical anti -pulling static load test anchor connection type anchor cage for engineering detection, including mounting frame, mounting hole is arranged in the up and down direction through, a plurality of are sequentially arranged to the circumference of mounting frame in mounting hole, every mounting hole is used for the upper end of one of the reinforcing bar of the measured base pile is inserted, the inner side wall of mounting hole is provided with anchor connection spare for the abutment of the circumference wall of the reinforcing bar of the measured base pile.

[0008] Through the above technical scheme, before the test, the mounting frame is placed above the measured base pile, and each mounting hole is aligned with the corresponding reinforcing bar, then the mounting frame is placed downward, so that the upper end of each reinforcing bar is inserted into the corresponding mounting hole, finally the circumference wall of the reinforcing bar is abutted by the anchor connection piece, so that the reinforcing bar is connected with the mounting frame, which is simple and fast.

[0009] Preferably, the anchor assembly includes a clamping block inserted into the mounting hole; the lower end wall of the clamping block is inclinedly provided with a clamping surface abutting against the inner side wall of the mounting hole, and the side wall of the clamping block away from the clamping surface abuts against the circumference wall of the reinforcing bar of the measured base pile; the distance between the clamping surface and the reinforcing bar of the measured base pile along the radial direction of the mounting hole gradually increases from bottom to top.

[0010] By adopting the above technical scheme, when the reinforcing bar of the measured base pile is fixed with the mounting frame, the clamping block is pushed downward, and the side of the clamping block away from the clamping surface can automatically abut against the circumference wall of the reinforcing bar; during the test, the mounting frame moves upward, and the inner side wall of the mounting hole has a component force along the radial direction of the mounting hole on the clamping surface, thereby facilitating the clamping block to further automatically abut against the reinforcing bar, and further improving the stability of the connection between the reinforcing bar and the mounting frame.

[0011] Preferably, the upper surface of the mounting frame at the position of each mounting hole is provided with a mounting sleeve, and the corresponding mounting hole is covered in the mounting sleeve; the mounting sleeve is threadedly connected with a pushing sleeve, and the pushing sleeve is provided with an abutting ring for abutting against the upper end wall of the clamping block.

[0012] By adopting the above technical scheme, after the reinforcing bar is inserted into the mounting hole and the clamping block is inserted into the mounting hole, the abutting sleeve is installed and rotated, so that the abutting ring pushes the clamping block in the direction of the mounting hole, thereby making the clamping block abut against the reinforcing bar, and making the reinforcing bar fixed with the mounting frame. The mounting sleeve, the abutting sleeve and the abutting ring cooperate, which is simple in structure and convenient to operate.

[0013] Preferably, the anchor connection piece includes a clamping block arranged in the mounting hole, one end of the clamping block is rotationally connected with the inner side wall of the mounting hole, the other end extends along the radial direction of the mounting hole to the axis direction of the mounting hole and is upwardly arranged; the end of the clamping block close to the axis of the mounting hole is used for abutting against the circumference wall of the reinforcing bar of the measured base pile.

[0014] By adopting the technical scheme, when the reinforcing bar of the measured foundation pile is inserted into the installation hole, the upper end wall of the reinforcing bar can push the clamping block upward, so that the end wall of the clamping block automatically abuts against the peripheral wall of the reinforcing bar; at this time, the end of the clamping block close to the reinforcing bar is arranged upwardly inclined. When the installation frame is subjected to upward traction during the test, the clamping block is subjected to pressure of the reinforcing bar along the length direction of the clamping block, so that the reinforcing bar is subjected to upward counterforce of the clamping block, thereby being beneficial to reducing the risk of downward movement of the reinforcing bar relative to the installation frame and causing the reinforcing bar to be separated from the installation hole, and being beneficial to improving the stability of the connection between the reinforcing bar of the measured foundation pile and the installation frame.

[0015] Preferably, a lower end of the installation hole is inserted with a dismounting rod, and the installation frame is provided with a limiting frame for abutting against a lower end wall of the dismounting rod; and an upper end wall of the dismounting rod is used for abutting against a lower surface of the clamping block.

[0016] By adopting the technical scheme, after the test is completed, the dismounting rod is moved upward, so that the dismounting rod pushes the clamping block upward, thereby enabling the clamping block to be separated from the reinforcing bar, so that the reinforcing bar is quickly separated from the installation hole, and the operation is simple and fast.

[0018] By adopting the technical scheme, when the dismounting rod is moved upward, after the extension rod moves to the outside of the connecting hole, the extension rod can be automatically rotated downward under the action of its own gravity to abut against the installation frame, thereby limiting the downward movement of the connecting rod and the dismounting rod, so that the clamping block remains in a state of being separated from the reinforcing bar, thereby reducing the operation of manually holding the dismounting rod, and the operation is more simple and convenient.

[0019] Preferably, the installation frame is provided with an elastic reset member for driving the clamping block to rotate downward.

[0020] By adopting the technical scheme, the elastic reset member is beneficial to enabling the clamping block to automatically abut against the peripheral wall of the reinforcing bar of the measured foundation pile, and is also beneficial to increasing the size of the interaction force between the clamping block and the reinforcing bar, thereby being beneficial to further improving the stability of the fixation of the reinforcing bar and the installation frame.

[0021] Preferably, the clamping block is provided with an abutting protrusion inserted into a position between two adjacent ribs of the reinforcing bar of the measured foundation pile.

[0022] By adopting the above technical solution, the position of the abutment protrusion between two adjacent protrusions of the reinforcing bar helps to restrict the movement of the peripheral wall of the reinforcing bar relative to the reinforcing bar, thereby further improving the stability of the reinforcing bar fixed relative to the abutment block, so as to improve the stability of the connection between the reinforcing bar and the mounting frame.

[0023] Preferably, the mounting bracket includes a mounting plate and a plurality of adjusting brackets; the mounting plate has an adjusting groove along its circumference, and the adjusting groove extends vertically; a plurality of adjusting grooves are sequentially arranged along the circumference of the mounting plate; the number of adjusting brackets is the same as the number of mounting holes, and the adjusting brackets correspond one-to-one with the mounting holes; each adjusting bracket includes an adjusting block inserted into the adjusting groove and a limiting block connected to the adjusting block, the limiting block abutting against the upper surface of the mounting plate; each mounting hole is located on the upper surface of the corresponding adjusting block; a gap is provided between the adjusting block and the inner wall of the adjusting groove to allow the adjusting block to move.

[0024] By adopting the above technical solution, the position of the corresponding adjustment block can be adjusted according to the quantity and distribution of the reinforcing bars in the foundation pile, thereby improving the applicability to reinforcing bars of different shapes or sizes.

[0025] Preferably, the lower surface of the limiting block is provided with a limiting protrusion, and the mounting plate is provided with a limiting groove for the limiting protrusion to be inserted. Multiple limiting grooves are arranged sequentially at intervals along the circumference and radial direction of the mounting plate.

[0026] By adopting the above technical solution, the limiting protrusion and the limiting groove are interlocked, which helps to limit the circumferential and radial movement of the adjustment block to be installed on the frame, thereby improving the stability of the adjustment block after position adjustment, and making it easier to insert the reinforcing bar into the corresponding installation hole.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Before the test, place the mounting frame above the pile to be tested, and align each mounting hole with the corresponding reinforcing bar. Then, place the mounting frame downwards so that the upper end of each reinforcing bar can be inserted into the corresponding mounting hole. Finally, use the anchor connector to tighten against the perimeter of the reinforcing bar, so that the reinforcing bar is connected to the mounting frame. The operation is simple and quick.

[0029] 2. When fixing the reinforcing bars of the pile to be tested to the mounting frame, push the snap-fit ​​block downwards. The snap-fit ​​side of the snap-fit ​​block away from itself can automatically abut against the periphery of the reinforcing bar. During the test, the mounting frame moves upwards. The force exerted by the inner wall of the mounting hole on the snap-fit ​​surface has a radial component along the mounting hole, which helps the snap-fit ​​block to further automatically abut against the reinforcing bar, thereby further improving the stability of the connection between the reinforcing bar and the mounting frame.

[0030] 3. When the mounting frame is subjected to upward traction, the clamping block is subjected to the pressure of the steel bar along the length direction of the clamping block itself, so as to cause the steel bar to be subjected to the reverse force of the clamping block upward, thereby facilitating to reduce the risk of the steel bar moving downward relative to the mounting frame and causing the steel bar to be separated from the mounting hole, and facilitating to improve the stability of the connection between the steel bar of the measured pile and the mounting frame.

Embodiment

[0047] The difference between the present embodiment and embodiment 1 is that:

The upper surface of the adjusting block 221 is downwardly provided with a mounting groove 2213, and the inner side wall of the mounting groove 2213 is connected with the inner side wall of the mounting hole 2211.

[0049] Referring to Figure 6 When the reinforcing bar 1 of the to-be-tested foundation pile is inserted into the mounting hole 2211, the upper end wall of the reinforcing bar 1 drives the clamping block 3 to rotate upwardly; when the upper end wall of the reinforcing bar 1 is separated from the clamping block 3, the clamping block 3 automatically abuts against the convex rib 12 of the reinforcing bar 1 under the action of the elastic reset member 2214, so that the side of the reinforcing bar 1 away from the clamping block 3 abuts tightly against the inner side wall of the mounting hole 2211, to limit the downward movement of the reinforcing bar 1 relative to the adjusting block 221, thereby reducing the possibility of the reinforcing bar 1 separating from the mounting hole 2211.

The upper end of the connecting rod 511 is provided with the extension rod 5111, one end of which is hinged to the connecting rod 511, and the other end extends upward. The end of the extension rod 5111 close to the connecting rod 511 is located in the connecting hole 2216; when the dismounting rod 5 moves upward, the extension rod 5111 can move upward synchronously to the outside of the connecting hole 2216; at this time, the extension rod 5111 automatically rotates downward under the action of its own gravity, so as to abut against the upper surface of the adjusting block 221, thereby limiting the downward movement of the dismounting rod 5, so that the clamping block 3 and the corresponding rib 12 of the reinforcing steel bar 1 remain in the disengaged state, thereby further facilitating the disengagement of the reinforcing steel bar 1 from the mounting hole 2211, and the operation is more convenient. In another embodiment, the connecting hole 2216 can also be provided on the limiting block 222.
