[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of the present application.
[0029] Please refer to Figures 1 to 4 .
[0030] This utility model provides a precast pile, including a pile body 10, which can be cast from concrete. Reinforcing bars can be installed inside the pile body 10 to improve its bearing capacity. A first connecting portion 112 is provided at the end face of the first end 11 of the pile body 10, and a second connecting portion 122 is provided at the end face of the second end 12 of the pile body 10. Two adjacent precast piles are connected through the first connecting portion 112 and the second connecting portion 122. The first end 11 and the second end 12 are two opposite ends of the pile body 10. Figure 1 As shown, the left end of pile 10 is the first end 11, and the right end is the second end 12. For two adjacent piles 10, the left end of one pile 10 is connected to the right end of the other pile 10, for example... Figure 4 As shown. The first end 11 has a first extension 111 on its side, and the second end 12 has a second extension 121 on its side. Both the first extension 111 and the second extension 121 extend towards the same side of the pile body 10, as shown. Figure 1 As shown, both the first extension 111 and the second extension 121 extend upwards towards the pile body 10. The first extension 111 and the second extension 121 enhance the vertical thickness of the first end 11 and the second end 12 of the pile body 10. The thickness direction refers to the extension direction of the first extension 111 and the second extension 121. When two adjacent precast piles are connected, as shown... Figure 4 As shown, since the thickness of the first extension 111 and the second extension 121 is relatively thicker than that of the pile body 10, the bearing capacity of the connection can be effectively strengthened, thereby reducing the risk of breakage. In addition, compared with the precast piles in the prior art where the thickness of the pile body 10 is the same as the thickness of its first end 11 and the second end 12, it is equivalent to saving the material of the pile body 10, thus effectively reducing the manufacturing cost.
[0031] In some embodiments, such as Figure 2 As shown, the pile body 10 is provided with at least one reinforcing protrusion 13, which can be integrally formed with the pile body 10. Furthermore, the first extension 111, the second extension 121, the first connecting portion 112, and the second connecting portion 122 can all be integrally formed with the pile body 10. Multiple reinforcing protrusions 13 are located between the first extension 111 and the second extension 121. The number of reinforcing protrusions 13 can be determined according to actual conditions. The greater the distance between the first extension 111 and the second extension 121, the greater the number of reinforcing protrusions 13. The reinforcing protrusions 13 can effectively improve the bearing capacity of the pile body 10. Figure 2As shown, the front end face and the rear end face of the pile body 10 are vertical planes, the reinforcing protrusion 13 extends along the direction from the front end face to the rear end face, and the width of the reinforcing protrusion 13 in the direction from the first end 11 to the second end 12 gradually decreases in the direction from the root of the reinforcing protrusion 13 to the tip of the reinforcing protrusion 13. Through the reinforcing protrusion 13 with this structure, the structural strength of the reinforcing protrusion 13 can be effectively improved, and the carrying capacity of the pile body 10 is further improved. Further, in order to reduce stress concentration, the junction position between the root of the reinforcing protrusion 13 and the pile body 10 is circularly arcuate, the junction position refers to the positions on both sides of the root of the reinforcing protrusion 13, the tip of the reinforcing protrusion 13 is a circular arc end, and the tip of the reinforcing protrusion 13 refers to the end away from the pile body 10.
[0032] In some embodiments, the first connecting part 112 is a clamping protrusion, the second connecting part 122 is a clamping groove, the shapes of the clamping protrusion and the clamping groove are matched with each other, two adjacent precast piles are connected with each other through the clamping protrusion and the clamping groove, and the two adjacent precast piles can be prevented from being separated from each other through the clamping protrusion and the clamping groove, thereby ensuring the connection effect. At least part of the structure of the second extending part 121 extends outward along the side of the clamping groove, as shown in Figure 1 and Figure 2 As shown, the part of the structure of the second extending part 121 on the right side extends upward from the upper end of the clamping groove, and the part of the structure of the clamping groove is located in the second extending part 121. For the pile body 10 with a relatively thin thickness, the second extending part 121 and the clamping groove with this structure can match with a clamping protrusion with a relatively large size, thereby ensuring the carrying capacity at the connection position.
[0033] In some embodiments, the cross sections of the first extending part 111 and the second extending part 121 are both right-angled trapezoids, the plane in which the right-angled side of the first extending part 111 is located is flush with the outer end face of the first end 11, as shown in Figure 1 As shown, the left end face of the first extending part 111 is flush with the left end face of the first end 11; the plane in which the right-angled side of the second extending part 121 is located is flush with the outer end face of the second end 12, as shown in Figure 1 As shown, the right end face of the second extending part 121 is flush with the right end face of the second end 12, and the end faces of the first extending part 111 and the second extending part 121 are in contact with each other when two adjacent precast piles are at a connection position, so as to form an isosceles trapezoidal structure. The inclined faces of the first extending part 111 and the second extending part 121 are circularly arcuate with the surface of the pile body 10, so as to reduce stress concentration.
[0034] In some embodiments, the clamping protrusion is a dovetail protrusion, and the clamping groove is a dovetail groove. Through the dovetail protrusion and the dovetail groove, the precast piles can be prevented from being separated from each other in the direction from the first end 11 to the second end 12, and the precast piles can also be prevented from being misaligned, thereby ensuring the connection stability of the two adjacent precast piles.
[0035] In some embodiments, the clamping protrusion is an arc-shaped protrusion, and the clamping groove is an arc-shaped groove, and the central angle of the arc-shaped protrusion and the arc-shaped groove is greater than 180°, so that the two adjacent precast piles can be hinged to each other, and the relative angle of the two precast piles can be adjusted to adapt to the installation environment.
[0036] In some embodiments, as shown in Figure 3 The first end 11 is provided with a first extension 111 on each side thereof, and the second end 12 is provided with a second extension 121 on each side thereof. The pile body 10, the first extension 111 and the second extension 121 form an H-shaped structure in cross section. The precast pile with the H-shaped structure can reduce the material of the pile body 10, thereby reducing the manufacturing cost.
[0037] In some embodiments, as shown in Figure 3 The first end 11 is provided with a first extension 111 on each side thereof, and the second end 12 is provided with a second extension 121 on each side thereof. The pile body 10, the first extension 111 and the second extension 121 form an H-shaped structure in cross section. The precast pile with the H-shaped structure can reduce the material of the pile body 10, thereby reducing the manufacturing cost.
