Description

Technical Field

[0001] This utility model relates to the field of anti-uplift pile technology, and in particular to an anti-uplift structural pile for buildings. Background Technology

[0002] In building construction, tension-resistant piles are commonly used. These piles rely on the friction between the pile and the soil to resist axial tensile forces. For example, Chinese patent application CN202022554104.0 discloses a prestressed tension-resistant pile structure for building construction. Specifically, by setting a support core, the compressive and support performance of the pile is improved. Simultaneously, multiple transverse reinforcing columns are horizontally welded to the outer surface of the support core. The transverse reinforcing columns improve the overall performance of the pile during the later pouring of the concrete layer. Horizontal and vertical fixing bars are installed between the reinforcing columns. The staggered arrangement of these bars effectively connects the horizontally reinforcing columns, thereby increasing the pile's rigidity. Furthermore, a conical steel fork is vertically installed at the bottom of the enlarged head. This not only facilitates pile installation but also aids in pile fixation. Additionally, barbs are provided on the outer surface of the conical steel fork to improve the pile's grip on the ground, thus enhancing its stability. However, the following technical issues remain:

[0003] The above structure uses a conical steel fork to increase gripping force, causing the upper width of the conical steel fork to be greater than the lower width. When the conical steel fork loosens in the concrete, the gripping performance of the barbs is greatly reduced. It can be seen that the pull-out resistance of the above structure is poor. Utility Model Content

[0004] To address the problem of poor pull-out resistance performance of existing pull-out piles as mentioned in the background section, this utility model provides the following technical solution:

[0005] A type of structural pile for building tension resistance, comprising a steel sheet pile sleeve;

[0006] The sheet pile sleeve contains a reinforcing cage, and a base is installed at the bottom of the sheet pile sleeve. Two tensile support legs for tensile support of the reinforcing cage are installed in the middle of the base.

[0007] The tensile support includes a swing rod, the upper end of which is equipped with a pressure block for pressing the reinforcing cage, and the lower end of which is equipped with a foot.

[0008] Furthermore, the inner wall of the sheet pile sleeve is pressed with multiple grooves, and the outer wall of the sheet pile sleeve is provided with protrusions.

[0009] Furthermore, the reinforcing cage includes vertical reinforcing bars, the outer walls of which are welded with multiple outer steel rings, and the inner walls of which are welded with multiple inner steel rings for stabilizing the vertical reinforcing bars.

[0010] Furthermore, the base includes a seat body, and the sheet pile sleeve is welded to the upper end of the seat body. The vertical reinforcing bar is placed at the upper middle part of the seat body, and two threaded holes are opened at the bottom of the seat body.

[0011] Furthermore, a limiting groove for swinging the swing arm is provided in the middle of the base, and a fixing rod for swinging the tensile support leg is installed in the middle of the limiting groove.

[0012] Furthermore, the upper end of the swing arm is provided with a limiting hole for cooperating with the fixing rod to limit the swing arm, and the upper end of the base is provided with multiple protrusions.

[0013] Furthermore, a connecting rod is installed in the middle of the swing arm, and a bolt for fixing the swing arm by engaging with a threaded hole is installed at one end of the connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention increases the contact area of ​​the base, allowing multiple protrusions at the upper end of the base to be firmly embedded in the concrete. Furthermore, the two pressure blocks compress the inner steel ring, making it difficult for the reinforcing cage to be pulled out during pull-out tests. When the bolts are tightened into the threaded holes, the pendulum is fixed, and the pressure blocks continuously compress the inner steel ring, ensuring the reinforcing cage is firmly embedded in the middle of the sheet pile sleeve and is not easily pulled out. When this invention is placed in the pile hole and concrete is poured in, vibration is applied to remove air bubbles from the concrete. After the concrete is completely dry, the protrusions can be better embedded in the concrete, increasing pull-out resistance. Attached Figure Description

Detailed Implementation

[0022] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0023] Please see Figures 1-4 This utility model provides a structural pile with tensile strength, including a sheet pile sleeve 10. The inner wall of the sheet pile sleeve 10 is pressed with multiple grooves 11, and the outer wall of the sheet pile sleeve 10 is provided with protrusions 12. The sheet pile sleeve 10 is a square steel plate. Before bending the sheet pile sleeve 10 into a circle, the sheet pile sleeve 10 is grooved and bent, so that one side of the sheet pile sleeve 10 has a groove 11 and the other side has a protrusion 12. When the sheet pile sleeve 10 is bent into a circle, the two sides of the steel plate are welded together. Through the arrangement of multiple grooves 11 and protrusions 12, after the concrete is poured, vibrated, and dried, the sheet pile sleeve 10 and the concrete can be well bonded together, thereby improving the tensile strength of the sheet pile sleeve 10.

[0024] The sheet pile sleeve 10 contains a reinforcing cage 20, which includes vertical reinforcing bars 21. Multiple outer steel rings 22 are welded to the outer wall of the vertical reinforcing bars 21, and multiple inner steel rings 23 are welded to the inner wall of the vertical reinforcing bars 21 for stabilizing them. The arrangement of multiple outer steel rings 22 and inner steel rings 23 allows the vertical reinforcing bars 21 to be stably placed in the middle of the inner cavity of the sheet pile sleeve 10.

[0025] The bottom of the sheet pile sleeve 10 is equipped with a base 30. The base 30 includes a seat body 31, and the sheet pile sleeve 10 is welded to the upper end of the seat body 31. The vertical reinforcing bar 21 is placed at the upper middle part of the seat body 31. Two threaded holes 32 are opened at the bottom of the seat body 31. Two tensile support legs 40 for resisting the tension of the reinforcing cage 20 are installed in the middle of the base 30. The two tensile support legs 40 are arranged in opposite directions. The tensile support legs 40 include a swing rod 41. The middle part of the seat body 31 is provided with a limiting groove 33 for swinging the swing rod 41. A fixing rod 34 for swinging the tensile support legs 40 is installed in the middle of the limiting groove 33. The two swing rods 41 are respectively located on both sides of the fixing rod 34.

[0026] The upper end of the swing rod 41 is fixedly equipped with a pressure block 42 for pressing the reinforcing cage 20. The pressure block 42 is an inclined rod. The lower end of the swing rod 41 is fixedly equipped with a foot 43, and the width of the foot 43 is greater than the width of the swing rod 41. By setting the foot 43, the contact area with the concrete is increased, thereby improving the pull-out resistance of this utility model. The upper end of the foot 43 is provided with multiple protrusions 44. The multiple protrusions 44 are fixed in the concrete, so that when the structural pile is pulled out, the protrusions 44 are stable in the concrete, and the foot 43 is not easy to slip due to the pull-out.

[0027] The upper end of the swing rod 41 is provided with a limiting hole 47 for limiting the swing rod 41 in conjunction with the fixing rod 34. The fixing rod 34 is inserted into the limiting hole 47. A connecting rod 45 is fixedly installed in the middle of the swing rod 41. One end of the connecting rod 45 is equipped with a bolt 46 for fixing the swing rod 41 in conjunction with the threaded hole 32. After the fixing rod 34 is inserted into the limiting hole 47 to limit the two swing rods 41, the two ends of the fixing rod 34 are respectively welded to the inner wall of the limiting groove 33. When the swing rod 41 is rotated, the connecting rod 45 can abut against the bottom of the seat 31, so that the bolt 46 can be screwed into the threaded hole 32 to fix the position of the swing rod 41.

[0028] After the sheet pile sleeve 10 provided by this utility model is welded to the outside of the base 30, the reinforcing cage 20 is placed in the middle of the sheet pile sleeve 10. Then, the tensile support leg 40 is installed in the middle of the base 31, so that the pressure block 42 is located at the upper end of the inner steel ring 23 at the lowest point of the reinforcing cage 20. When the bolt 46 is tightened into the threaded hole 32, the pressure block 42 can press the inner steel ring 23, so that the reinforcing cage 20 can be stably placed in the middle of the sheet pile sleeve 10, and the reinforcing cage 20 is not easy to be pulled out from the sheet pile sleeve 10. The utility model is placed in the pile hole and concrete is poured in and vibrated to remove air bubbles in the concrete. After the concrete is completely dry, the protrusion 44 can be well inserted into the concrete, increasing the pull-out resistance.

[0029] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
