Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a portable limiter for an inner column of a cast-in-place pile and a limiting method thereof. Background Art

[0002] In the construction of a solar bracket, it is often necessary to use a cast-in-place pile to fix a column: insert the column into the pile hole and then pour concrete into the pile hole, and the column is fixed after the concrete solidifies. However, during the casting process of the cast-in-place pile, due to improper construction operations, external force interference, or soil disturbance, the column is often difficult to maintain verticality, resulting in a connection error with the bracket in the later stage. On-site, the method of manually adjusting the verticality of the column is usually adopted, but this method is inefficient and is easily restricted by the construction environment. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a portable limiter for an inner column of a cast-in-place pile and a limiting method thereof, which can be quickly installed in place, clamp and limit the column during the casting of the cast-in-place pile, maintain the verticality of the column, and improve the construction efficiency.

[0004] To achieve the above purpose, the technical solution adopted by the present invention for a portable limiter for an inner column of a cast-in-place pile includes:

[0005] A support ring;

[0006] A bracket for supporting the support ring directly above the pile hole of the cast-in-place pile;

[0007] A leveling ring, the leveling ring is located at the top of the support ring, and a plurality of leveling knobs are connected between the leveling ring and the support ring at intervals;

[0008] A support rod rotatable about an axis perpendicular to the leveling ring, one end of the support rod is rotatably connected to the top of the leveling ring, and the length of the support rod is not less than the diameter of the leveling ring;

[0009] A clamping member for clamping the column, the clamping member is slidably connected to the support rod along the length direction of the support rod.

[0010] The portable limiter for an inner column of a cast-in-place pile of the present invention is further improved in that a spirit level is connected to the top of the leveling ring.

[0011] The portable limiter for an inner column of a cast-in-place pile of the present invention is further improved in that the bracket includes a plurality of legs with adjustable lengths, and the plurality of legs are hinged to the outer periphery of the support ring at intervals.

[0012] A further improvement of the portable limiter for the inner column of the cast-in-place pile is that a pointed tip for inserting into the ground is connected to one end of the leg relatively far from the support ring.

[0013] A further improvement of the portable limiter for the inner column of the cast-in-place pile is that the support rod and the leveling ring are connected by a second bolt. A threaded hole is vertically opened at the top of the leveling ring. One end of the screw rod of the second bolt is screwed into the threaded hole, and the other end extends out of the leveling ring and forms an extension section. The support rod is rotatably sleeved on the extension section, and the nut of the second bolt is screwed and sleeved on the extension section to limit the rotation of the support rod by locking to the extension section.

[0014] A further improvement of the portable limiter for the inner column of the cast-in-place pile is that one end of the clamping member is connected with a connecting rod. The connecting rod and the support rod are connected by a third bolt. The connecting rod is rotatably sleeved on the screw rod of the third bolt. A through groove for the screw rod of the third bolt to slide through is opened along the length direction of the support rod. The diameters of the bolt head and the nut of the third bolt are both larger than the through groove.

[0018] Step 3: Adjust a plurality of leveling knobs until the leveling ring is in a horizontal state;

[0019] Step 4: Rotate the support rod around the axis perpendicular to the leveling ring and slide and adjust the position of the clamping member on the support rod until the clamping member moves to the designed installation position of the column;

[0020] Step 5: Insert the column into the pile hole of the cast-in-place pile and use the clamping member to clamp and limit it;

[0021] Step 6: Pour concrete into the pile hole of the cast-in-place pile to anchor the column therein.

[0022] A further improvement of the method for limiting the position of the inner column of the cast-in-place pile of the present invention is that a spirit level is connected to the top of the leveling ring;

[0023] When performing the above step 3, adjust a plurality of leveling knobs until the bubble in the spirit level is centered.

[0024] A further improvement of the limiting method for the inner column in the cast-in-place pile of the present invention lies in that the support rod is connected to the leveling ring through a second bolt. A threaded hole is vertically opened at the top of the leveling ring. One end of the screw rod of the second bolt is screwed into the threaded hole, and the other end extends out of the leveling ring and forms an extension section. The support rod is rotatably sleeved on the extension section, and the nut of the second bolt is screwed and sleeved on the extension section;

[0025] When performing the above step 4, after rotating the support rod in place, screw the nut of the second bolt to clamp the support rod between the nut of the second bolt and the leveling ring, restricting the rotation of the support rod.

[0026] A further improvement of the limiting method for the inner column in the cast-in-place pile of the present invention lies in that one end of the clamping member is connected with a connecting rod. The connecting rod is connected to the support rod through a third bolt. The connecting rod is rotatably sleeved on the screw rod of the third bolt. A through groove for the screw rod of the third bolt to slide through is opened along the length direction of the support rod. The diameters of the bolt head and the nut of the third bolt are both larger than the through groove;

[0027] When performing the above step 4, after the hoop moves to the designed installation position of the column, screw the nut of the third bolt to clamp the connecting rod between the nut of the third bolt and the support rod, restricting the sliding and rotation of the connecting rod.

[0028] Compared with the prior art, the advantages of the present invention are as follows:

[0029] The clamping member can slide along the support rod, and the support rod can also rotate around the axis perpendicular to the leveling ring. The clamping member can be flexibly adjusted to the designed installation position of the column. BRIEF DESCRIPTION OF THE DRAWINGS
