Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools for cast-in-place pile construction, and particularly relates to an auxiliary device for breaking pile heads. Background Art

[0002] In recent years, with the rapid development of urban economies and the continued deepening of urbanization, municipal construction, a traditional industry, has shown a trend toward large-scale development. Construction projects inevitably involve a large number of pile foundations, and pile head removal is a key component of this work. Pile head removal refers to the practice of maintaining the top elevation of the cast-in-place pile by 0.8-1.0 m above the designed top elevation during pouring to ensure the strength of the concrete head. However, the portion of the pile head that rises above the designed top elevation must be chiseled away during subsequent construction. This process is known as "pile head removal." Modern methods for pile head removal primarily involve manual and mechanical methods. Mechanical pile head removal primarily utilizes complex machinery and is costly. Manual pile head removal can lead to significant deformation of the rebar during removal. Furthermore, manual measurement is required to determine the pile head's position before excavation. The resulting pile head is unformed and difficult to handle, significantly impacting the aesthetics of the structure and increasing the cost and time of rebar straightening and pile head removal, as well as significant labor costs.

[0022] Example 1:

[0023] See also Figure 1-Figure 3 An auxiliary device for quickly breaking a pile head comprises several steel sleeves 1, each having a diameter larger than that of the pile head reinforcement. Adjacent steel sleeves 1 are connected by an annular connecting plate 2, through which a pile breaking hole 3 is formed. The top of the annular connecting plate 2 is connected to several hinges 4, each hinge 4 being connected to the annular connecting plate 2 at one end and connected to a point at the other end. Pile breaking anchors are detachably connected to the pile breaking holes 3. Each hinge 4 is connected to a lifting ring 5, which can lift the pile head along with it.

[0024] In order to prevent the pile-breaking hole 3 from being poured into the inner wall of the concrete after pouring, a loosening sleeve 6 is provided on the outer side of the annular connecting plate 2, and the inner side of the loosening sleeve 6 is in contact with the annular connecting plate 2; the inner side of the loosening sleeve 6 is connected to the template column 7, and the diameter of the template column 7 is the same as the radius of the pile-breaking hole 3. The template column 7 can extend into the pile-breaking hole 3. The loosening sleeve 6 is elastic and can be wrapped around the outside of the device. After pouring is completed, it can be removed for subsequent pile-breaking operations.

[0025] The pile-breaking anchor device in this embodiment includes two symmetrically arranged pile-breaking rods 8, one end of which is hinged via a hinged joint 9 and the other end is separated. The hinged end of the two pile-breaking rods 8 fits into a drill bit 12 for striking the pile head, while the separated ends of the two pile-breaking rods 8 are bent to form pile-breaking anchors 10. A pile-breaking block 11 is inserted between the two pile-breaking rods 8. The block 11 is conical on one side and hemispherical on the other. A hammer rod 13 is provided on the outside of the pile-breaking block 11 for striking the block 11. The inclination angle of the cone at one end of the pile-breaking block 11 is greater than the angle between the two pile-breaking rods 8. A compression spring is connected to the inner side of the hinged ends of the two pile-breaking rods 8. This pile-breaking anchor device only requires a hammer or other mechanical hammer to strike the hammer rod 13. The hammer rod 13 strikes the pile-breaking block 11, driving the pile-breaking rod 8 outward and forward, making it easier to break the pile head.

[0026] Directions:

[0027] First, a steel sleeve 1 is made according to the number of steel bars in the steel cage, and each steel sleeve 1 is connected in a ring shape through an annular connecting plate 2. Before being inserted into the steel cage, the inner wall of the sleeve is lubricated with a lubricant to facilitate its removal from the steel cage later; the pile-breaking hole 3 is adjusted to the position of the pile head, which reduces the step of measuring the position of the pile head again, and the loosening sleeve 6 is installed; concrete is poured, and the hinge 4 is poured into the inside so that the lifting ring 5 is exposed at the top of the pile head; after the pouring is completed, the loosening sleeve 6 is removed, and the pile head is separated from the bottom with a pile-breaking anchor, and finally the pile head is quickly lifted out with a crane.

[0028] Example 2:

[0029] The remaining components of this embodiment are identical to those of the first embodiment, except that the pile-breaking anchor includes a special-shaped pile-breaking block 16 with a conical shape on one side and a first inclined surface 17 on the other. A special-shaped hammer rod 14 is provided on the outside of the special-shaped pile-breaking block 16 for striking the special-shaped pile-breaking block 16. The special-shaped hammer rod 14 has a second inclined surface 15 parallel to the inclined surface of the special-shaped pile-breaking block 16, and the first inclined surface 17 and the second inclined surface 15 are vertically offset. This pile-breaking anchor has a simple structure and can also achieve the effect of separating the pile head by impacting along both the radial and axial directions.

[0030] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
