Description

Technical Field

[0001] The utility model relates to the technical field of supporting piles, in particular to a prestressed high-strength concrete supporting pile. Background Art

[0002] Prestressed high-strength concrete support piles are a form of structural support that applies a pre-designed tension force inside the concrete pile body, allowing the pile body to better bear the load and resist deformation when under stress, thereby playing the role of reinforcing and supporting the structure. Compared with ordinary concrete support piles, prestressed high-strength concrete support piles have higher bearing capacity and earthquake resistance.

[0003] The patent with the current publication number CN205636734U discloses a prestressed high-strength concrete hollow support pile, including a steel cage skeleton and a concrete pile body; its cross section is a polygonal hollow tube, including a flange plate on the pile body, a lower flange plate on the pile body, a left leg on the pile body, a right leg on the pile body, a tenon on the pile body and a mortise on the pile body; the flange plate on the pile body and the lower flange plate on the pile body are symmetrically arranged, and both are formed by cross-welding of more than two longitudinal prestressed main bars and more than two hoop bars; hoop bars are evenly distributed between the flange plate on the pile body and the lower flange plate on the pile body; the tenon on the pile body and the mortise on the pile body are respectively located on one side of the left leg on the pile body and one side of the right leg on the pile body, and the tenon on the pile body and the mortise on the pile body are meshed and matched; grouting reserved holes and grooves are symmetrically arranged between the tenon on the pile body and the mortise on the pile body. The device has a stable structure, good soil consolidation and water-stopping effect, simple construction, low engineering cost, adopts mechanized and automated production and processing procedures, short construction period and high efficiency.

[0004] However, the above-mentioned prestressed high-strength concrete supporting piles still have the following problems:

[0005] At present, some of the prestressed high-strength concrete support piles are cylindrical, and the support piles are generally long and medium. This means that when the support piles are transported from the manufacturer to the construction site, multiple support piles need to be stacked together. During the transportation process, these circular support piles are mostly misplaced. For example, if the cylindrical support pile at the bottom slides to both sides due to vehicle bumps or other reasons, it may cause several circular support piles on the upper part to slide down together instantly, posing a major safety hazard. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a prestressed high-strength concrete support pile. When the user transports a number of support pile bodies by vehicle, the front support plate and the rear support plate at both ends of the support pile bodies in the bottom row can be placed on the ground, and then locked by an extrusion assembly and a limit assembly, thereby preventing the support pile bodies from running off the track.

[0007] The utility model provides the following technical solutions: a prestressed high-strength concrete supporting pile, comprising a supporting pile body, a steel bar installed at the tapered end of the supporting pile body and a plurality of evenly distributed threaded holes opened at the flat end of the supporting pile body, the outer wall of the steel bar is sleeved and rotatably connected with a front supporting plate, the side of the front supporting plate away from the supporting pile body is connected with an extrusion component, the inner wall of the extrusion component is abutted against the outer wall of the steel bar, the inner walls of two symmetrical threaded holes are both threadedly connected with bolts, a connecting plate is connected between the two bolts, the side of the connecting plate away from the supporting pile body is connected with a limiting component, and the other end of the limiting component is connected with a rear supporting plate.

[0009] Furthermore, the cross sections of the extrusion ring and the plurality of sector blocks are all arranged in a trapezoidal shape.

[0010] Furthermore, the limiting assembly includes a threaded rod and a threaded ring, one end of the threaded rod is fixedly connected to the side of the connecting plate away from the supporting pile body, the other end of the threaded rod passes through the rear support plate and the threaded ring, and is threadedly connected to the inner wall of the threaded ring, and the side of the threaded ring close to the supporting pile body is abutted against the side of the rear support plate away from the supporting pile body.

[0011] Furthermore, both ends of the connection plate are provided with limit openings, and the ends of the two bolts away from the supporting pile body are respectively located in the two limit openings.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This type of prestressed high-strength concrete support pile is formed by arranging a front support plate outside the steel bar at the front end of the support pile body, connecting bolts and connecting plates through threaded holes at the rear end of the support pile body, and then connecting the rear support plate through the connecting plate, and the front support plate and the rear support plate are limited by extrusion components and limit components respectively.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 5 A prestressed high-strength concrete supporting pile comprises a supporting pile body 1, a steel bar 9 installed at the tapered end of the supporting pile body 1 and a plurality of evenly distributed threaded holes 101 provided at the flat end of the supporting pile body 1, a front supporting plate 7 is sleeved on the outer wall of the steel bar 9 and rotatably connected, an extrusion assembly is connected to the side of the front supporting plate 7 away from the supporting pile body 1, an inner wall of the extrusion assembly abuts against the outer wall of the steel bar 9, wherein the inner walls of two symmetrical threaded holes 101 are both threadedly connected with bolts 3, a connecting plate 2 is connected between the two bolts 3, a limiting assembly is connected to the side of the connecting plate 2 away from the supporting pile body 1, and a rear supporting plate 5 is connected to the other end of the limiting assembly.

[0022] The prestressed high-strength concrete support pile in the utility model is similar to the existing prestressed high-strength concrete support pile structure, such as the prestressed high-strength concrete hollow support pile disclosed in the patent with publication number CN205636734U. Figures 1 to 5 As shown, when the prestressed high-strength concrete support piles in the utility model are transported by vehicles, when the support pile body 1 in the bottom row is placed by a crane or other equipment, the front support plates 7 and the rear support plates 5 at both ends of the support pile body 1 can be first rotated to be perpendicular to the ground, and then the support pile body 1 can be placed normally on the vehicle's cargo box by the crane. When the support pile body 1 is placed on the cargo box, the front support plates 7 and the rear support plates 5 at both ends will also be placed exactly on the vehicle's cargo box, and then the front support plates 7 and the rear support plates 5 are locked by the extrusion assembly and the limit assembly respectively, so that the front support plates 7 and the rear support plates 5 cannot rotate, thereby limiting the shaking and deviation of the support pile body 1.

[0023] Please refer to Figure 4 The extrusion assembly includes an extrusion ring 8 and a plurality of sector blocks 10. One end of each of the sector blocks 10 is fixedly connected to the side of the front support plate 7 away from the support pile body 1. The inner walls of each of the sector blocks 10 are against the outer walls of the steel bars 9. The extrusion ring 8 is sleeved on the outer walls of the sector blocks 10 and is threadedly connected to the outer walls of the sector blocks 10. The cross sections of the extrusion ring 8 and the sector blocks 10 are both trapezoidal.

[0024] More specifically, when the front support plate 7 needs to be limited and locked, it is only necessary to rotate the extrusion ring 8. After the extrusion ring 8 is rotated, it will move outward along the plurality of fan-shaped blocks 10. Because the cross-sections of the extrusion ring 8 and the fan-shaped blocks 10 are both trapezoidal, when the extrusion ring 8 and the fan-shaped blocks 10 cooperate to extrude, the plurality of fan-shaped blocks 10 can be tightly squeezed against the surface of the steel bar 9, thereby limiting the front support plate 7 from rotating.

[0025] Special mention should be made here:

[0026] When the supporting pile body 1 needs to be inserted into the ground later, it is only necessary to loosen the extrusion ring 8 and the extrusion between the fan-shaped block 10 and the steel bar 9, and the front support plate 7 can be slid out along the surface of the steel bar 9, so that the subsequent construction will not be affected.

[0027] Please refer to Figure 1 and Figure 5 The limiting assembly includes a threaded rod 4 and a threaded ring 6. One end of the threaded rod 4 is fixedly connected to the side of the connecting plate 2 away from the supporting pile body 1. The other end of the threaded rod 4 passes through the rear supporting plate 5 and the threaded ring 6, and is threadedly connected to the inner wall of the threaded ring 6. The side of the threaded ring 6 close to the supporting pile body 1 is against the side of the rear supporting plate 5 away from the supporting pile body 1.

[0028] More specifically, when the rear support plate 5 needs to be limitedly locked, it is only necessary to rotate the threaded ring 6. After the threaded ring 6 rotates, it will move along the surface of the threaded rod 4, and then the rear support plate 5 can be pushed toward the direction of the connecting plate 2 during the movement until the two are tightly squeezed together, thereby completing the limit.

[0029] Special mention should be made here:

[0030] 1. Although some threaded holes 101 may not be exactly parallel to the ground due to placement, the rear support plate 5 rotates with the threaded rod 4 as the axis, and the threaded rod 4 is exactly the center of the support pile body 1. Therefore, no matter what inclination angle the connecting plate 2 is at, the bottom surface of the rear support plate 5 will be flush with the outer wall of the support pile body 1.

[0031] 2. When the supporting pile body 1 is subsequently inserted into the ground, the connecting plate 2 can be separated from the threaded hole 101 by two bolts 3, and then several components at the rear of the supporting pile body 1 can be disassembled from the supporting pile body 1, so it will not affect subsequent processing.

[0032] Please refer to Figure 5 , both ends of the connecting plate 2 are provided with limiting openings 201, and the ends of the two bolts 3 away from the supporting pile body 1 are respectively located in the two limiting openings 201. By providing the limiting openings 201 and placing the two bolts 3 therein, the bolts 3 can be prevented from hindering the rotation of the rear support plate 5.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
