Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place pile repair, in particular to a pile head repair device. Background Art

[0002] Related technologies include a pile head repair device disclosed in application publication number CN203654278U. The handle of the wire is convenient for tightening the wire, and the "L"-shaped design of the pin facilitates the insertion and removal of the pin, making the operation more convenient. The inner wall of the annular template is flat and smooth, and the groove design of the outer wall makes the wire firmly fixed, effectively ensuring the quality of pile head molding, saving labor, and shortening the construction period.

However, when the pile head needs to be broken and the pile head elevation is insufficient and concrete needs to be re-poured, when the pile head needs to be re-fixed at the top, it is impossible to expand and fix it in an annular manner. Only the completely re-poured concrete can be fixed, which has great limitations. Utility Model Content

When the extension block enters into the groove, the inclined second semicircular block will be in a parallel state when it is pushed into the groove. When the second semicircular block inside the extension block is completely in contact with the first semicircular block inside the groove, the elastic band pulls one side of the second semicircular block to tilt the second semicircular block, and at the same time the spring also contracts, pulling the inclined plate to tilt, so that the first semicircular block moves according to the angle of the first arc block, thereby tilting, so that the second semicircular block and the first semicircular block tilt at the same time, and when the two semicircular blocks tilt at the same time, they will be blocked by the groove when shrinking, so that the left half mold unit and the right half mold unit are closely fitted, and when the concrete is poured, the concrete is prevented from flowing out, thereby improving the practicality of the device.

[0015] 2. The utility model provides a fixing mechanism. When concrete is poured inside the fastening mechanism, the concrete will expand when solidifying. While expanding, the fastening mechanism is subjected to outward force. When the left half mold unit and the right half mold unit expand outward, the left half mold unit and the right half mold unit squeeze the first extrusion arc plate. The squeezed first extrusion arc plate moves to both sides through the slide groove. When the first extrusion arc plate moves to a certain distance, the first extrusion arc plate first contacts the bottom of the arc plate. When the arc plate is squeezed, it rotates. While the bottom of the rotating arc plate moves to both sides, the tops of the arc plates approach each other. The approaching tops of the arc plates push the second extrusion arc plate inward, so that the second extrusion arc plate is tightly attached to the outer surface of the first extrusion arc plate, thereby preventing the left half mold unit and the right half mold unit from continuing to expand outward, thereby improving the practicability of the device.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
