Description

Technical Field

[0001] The utility model relates to the field of pipe piles, in particular to a supporting pile. Background Art

[0002] At present, pipe piles generally refer to prestressed concrete pipe piles, and there are several types, such as PC, PHC, etc., which are generally used in industrial and civil buildings, ports, municipal administration, bridges, roads, railways and water conservancy projects, etc. They are mainly used as foundation materials, with the characteristics of fast construction, good geological adaptability, and economic savings.

[0003] When the pipe pile is first driven into the soil layer from the ground, a pile tip needs to be welded to one end of the pipe pile so that it will not be affected by isolated rocks and hard sand layers in the soil layer during the sinking process, making the driving of the pipe pile smoother and preventing unstable sinking.

[0004] The existing pile tip is generally connected to the end plate by welding. Before welding the pile tip, the pile body needs to be pre-fixed, and the pile tip needs to be flush with one end face of the end plate. At this time, the pile tip needs to be supported by manpower or equipment to prevent the pile tip from falling, which will greatly reduce the efficiency and quality of manual welding. Therefore, with the expansion of the market demand for pile products, the continuous expansion of the extended use of pipe piles, and the continuous extension of the use of hydraulic support, in order to meet customer needs, technical improvements are made on the original structure of pipe piles to facilitate project use.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 7 The utility model provides a supporting pile, including a steel cage 1 and a pile body 2. One end of the main reinforcement 4 of the steel cage 1 is clamped on the first end plate 3 through its upsetting head, and the other end passes through the second end plate 9 and is exposed on the outer surface of the end plate, and its end is provided with an upsetting head or a thread.

[0030] The steel cage 1 includes not only main bars 4 but also stirrups. The main bars 4 and stirrups are combined to form the steel cage 1. The steel cage 1 is a prior art and will not be described in detail here. The pile body 2 is formed by pouring concrete centrifugally and heating after the steel cage 1 is placed in a mold. The exposed end is set as a swaging head or a thread to prepare for the subsequent tensioning of the main bars 4.

[0031] In addition, one end of the main reinforcement 4 of the reinforcement cage 1 is exposed from the first end plate 3 and has a length of 8-20 cm. In order to avoid adding anchor reinforcement separately when connecting the pile and the crown beam, the construction is simple and convenient.

[0032] Furthermore, a pile tip 5 is connected to the first end plate 3, and a connecting piece 7 is provided on the first end plate 3. The connecting piece 7 is engaged with the pile tip 5 through a locking piece 8, and a locking piece provided on the pile tip 5 pushes the locking piece 8 so that the locking piece 8 is tightly pressed against the connecting piece 7.

[0033] In order to better connect the first end plate 3 with the pile tip 5, the connecting piece 7 is first screwed onto the first end plate 3, and then the pile tip 5 is taken so that the slot 51 on the pile tip 5 corresponds to the connecting piece 7, and then the pile tip 5 is moved close to the first end plate 3, so that the connecting piece 7 forces the engaging piece 8 in the pile tip 5 to move in the opposite direction of the connecting piece 7. After the connecting piece 7 enters the slot 51, the engaging piece 8 returns to its original position by elastic force, restricting the connecting piece 7 from being separated from the pile tip 5, and the locking piece cooperates with the first end plate 3 and makes it abut against the engaging piece 8, further tightening the connecting piece 7, making the connection between the pile tip 5 and the first end plate 3 more stable, and also improving the subsequent welding efficiency and welding quality of the pile tip 5 and the first end plate 3.

[0034] Specifically, a plurality of threaded holes 31 are arranged at annular intervals on the first end plate 3, and the connecting member 7 includes: a first column 71, and a threaded end 711 is arranged on the first column 71, and cooperates with the threaded hole 31, so that the first column 71 is connected to the first end plate 3, thereby simplifying the structure of the first end plate 3, and through the detachable connection method, the difficulty of manufacturing the components separately is reduced.

[0035] A second column 72 is disposed on the first column 71 , and a diameter of the second column 72 is larger than that of the first column 71 , so that the second column 72 can be subsequently engaged in the pile tip 5 .

[0036] A slot 51 is provided in the pile tip 5, and the engaging member 8 is an elastic engaging member located on both sides of the slot 51 and extending into the slot 51. Slide grooves are provided on both sides of the slot 51, and the elastic engaging member includes: a spring 83 provided in the slide groove, a block 82 connected to the spring 83, and the block 82 is extended into the slot 51 by the elastic force generated by the spring 83. A wedge structure 81 is provided on the outward end surface of the block 82, and the inward end is a vertical end. The connecting member 7 squeezes the wedge structure 81 of the block 82 to extend into the slot 51, and the vertical end of the block 82 restricts the connecting member 7 from leaving the slot 51.

[0037] Among them, the second column 72 squeezes the block 82, forcing the spring 83 to shrink into the slide groove. Due to the different diameters of the first column 71 and the second column 72, when the second column 72 completely enters the slot 51, the elastic force generated by the spring 83 causes the block 82 to move further in the slot and makes the block 82 abut against the first column 71. Preferably, one end of the block 82 may be an arc structure that is compatible with the first column 71 or the second column 72.

[0038] In addition, the locking member includes: a screw rod 61, an abutting end portion 62 disposed on the screw rod 61, the screw rod 61 is threadedly connected to the pile tip 5, and the abutting end portion 62 extends into the slide groove. A chamfered structure is disposed on the abutting end portion 62, and the structure abuts against the clamping block 82. When the screw rod 61 is screwed, the chamfered structure on the abutting end portion 62 contacts the clamping block 82, so that the clamping block 82 is further pushed into the clamping groove 51, and firmly clamps the first column 71, so that the pile tip 5 is more firmly connected to the first end plate 3.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
