Abstract
Description
Technical Field
[0001] This patent relates to the field of shot blasting technology, specifically a steel pipe pile for reinforcing the foundation of a building. Background Art
[0002] Buildings need to insert steel pipe piles into foundation pits to increase the stability of the buildings. Existing steel pipe piles are mostly composed of two sections of pipe bodies for easy transportation. The two sections of the pipe bodies need to be assembled before being inserted into the pit. Connecting rings are provided on both sides of the pipe bodies, and then bolts are passed through the connecting rings for connection. However, after the concrete solidifies in the pit, the solid concrete is prone to lateral extrusion of the pipe body, and the extrusion force will act on the bolts. In severe cases, the bolts will be damaged and the two sections of the pipe body will be separated, reducing the reinforcement capacity of the steel pipe piles. For this reason, we propose a steel pipe pile for reinforcing the foundation of a building. Utility Model Content

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a steel pipe pile for reinforcing the foundation of a building, comprising a steel pipe pile 1, a pit 2 and a reinforcing plate 4, the steel pipe pile 1 is located in the pit 2, a connecting groove 3 from top to bottom is provided on the inner wall of the pit 2, the bottom of the reinforcing plate 4 is fitted on the top of the pit 2, a positioning groove is provided at the bottom of the reinforcing plate 4, the top of the steel pipe pile 1 is inserted into the positioning groove, the top of the steel pipe pile 1 and the middle of the reinforcing plate 4 are both provided with a casting hole 5, the top of the reinforcing plate 4 is provided with a mounting hole 6, the top of the steel pipe pile 1 is integrally formed with a screw 7, the top of the screw 7 passes through the mounting hole 6 and is screwed with a nut 8;
[0020] The steel pipe pile 1 includes a first tube body 9, a second tube body 10 and a reinforcement ring 11. The side walls of the first tube body 9 and the second tube body 10 are both provided with connecting holes 12. The inner side wall of the reinforcement ring 11 is sleeved on the joint of the outer side walls of the first tube body 9 and the second tube body 10. The left and right ends of the outer side walls of the first tube body 9 and the second tube body 10 are both provided with thread grooves 13. The side walls of the reinforcement ring 11 are both provided with circular holes 14 on both sides and at both ends. There are four circular holes 14. Bolts 15 are arranged in the circular holes 14. The ends of the bolts 15 are screwed in the thread grooves 13.
[0021] The inner diameter of the reinforcement ring 11 matches the outer diameters of the first tubular body 9 and the second tubular body 10 .
[0022] Specifically, the bottom of the first tube body 9 and the left and right ends of the top of the second tube body 10 are both provided with reinforcement grooves 16 , and reinforcement rods 17 are inserted into the reinforcement grooves 16 .
[0023] When the concrete in the pit 2 laterally squeezes the first tube body 9 and the second tube body 10 , the reinforcing rod 17 can also increase the connectivity between the first tube body 9 and the second tube body 10 .
[0024] Specifically, an annular cavity 18 is provided on the inner side wall of the circular hole 14 , and an annular ring 19 is integrally formed on the side wall of the bolt 15 , and the annular ring 19 is located in the annular cavity 18 .
[0025] The circular ring 19 is arranged in the circular ring cavity 18 to increase the integration effect of the bolt 15 and the reinforcement ring 11. This facilitates the bolt 15 and the reinforcement ring 11 to be an integrated structure during early transportation, thereby avoiding loss of the bolt 15 and facilitating subsequent installation.
[0026] Specifically, the side wall of the bolt 15 does not contact the inner wall of the circular hole 14 .
[0027] Specifically, the diameter of the circular ring 19 matches the inner diameter of the circular ring cavity 18 , and the outer wall of the circular ring 19 is slidably mounted on the inner wall of the circular ring cavity 18 .
[0028] By not allowing the side wall of the bolt 15 to contact the inner wall of the circular hole 14, the resistance when the bolt 15 is rotated can be reduced. At the same time, by allowing the ring 19 to slide on the inner wall of the circular cavity 18, the bolt 15 can only move left and right in the circular hole 14, thereby preventing the bolt 15 from shaking in the circular hole 14 and facilitating the installation of the bolt 15 in the threaded groove 13.
[0029] Specifically, the left and right ends of the inner side walls of the first tube body 9 and the second tube body 10 are integrally formed with a transverse plate 20 , and the transverse plate 20 is semicircular.
[0030] When the concrete solidifies inside the steel pipe pile 1 , the upward tensile force of the steel pipe pile 1 can be increased by providing the transverse plate 20 .
[0031] Specifically, a circular groove 21 is provided at the top end of the inner wall of the mounting hole 6 , and the nut 8 is completely located in the circular groove 21 .
[0032] The circular groove 21 is provided to accommodate the nut 8 , thereby increasing the flatness of the top of the reinforcing plate 4 .
[0033] Working principle: During the early assembly, the reinforcement rod 17 is inserted into the reinforcement groove 16, and the end of the bolt 15 can be screwed into the threaded groove 13 on the outer wall of the first tube body 9 and the second tube body 10, and the steel pipe pile 1 is inserted into the pit 2, and the reinforcement plate and the steel pipe pile 1 are connected as a whole through the nut 8, and concrete is poured into the steel pipe pile 1 through the casting hole 5. The concrete can enter the pit 2 and the connecting groove 3 through the connecting hole 12 until it solidifies. The connection between the first tube body 9 and the second tube body 10 is connected by the reinforcement ring 11 instead of the traditional vertical bolts, which has a larger external pressure-bearing surface, increases the connectivity of the first tube body 9 and the second tube body 10, and thereby improves the reinforcement effect of the overall steel pipe pile 1.
