Description

Technical Field

[0001] The utility model relates to the field of pipe piles, in particular to a prestressed end-slab-free concrete pipe pile. Background Art

[0002] Prestressed concrete pipe piles are hollow cylindrical slender concrete prefabricated components. Prestressed concrete pipes are divided into two types: with end plates and without end plates. Prestressed concrete pipes with short plates are mainly composed of cylindrical pile bodies, end plates and steel sleeves. Piles without end plates do not need to be equipped with end plates, which can reduce the production cost of pipe piles and does not have the problem of end plate corrosion. Most pipe piles are equipped with end plates at the ends to facilitate the subsequent docking and installation of pipe piles. However, when the end plates are connected, the staff needs to repeatedly adjust them to align the connection holes of the end plates, which is time-consuming and labor-intensive. Summary of the invention

[0003] The technical problem to be solved by the utility model is that when the end plates are connected relatively, the staff needs to make repeated adjustments so that the connection holes of the end plates are aligned, which is time-consuming and labor-intensive.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a prestressed end plate-less concrete pipe pile, including a pipe pile body and a frame arranged on the inner wall of the pipe pile body, the upper and lower ends of the pipe pile body are symmetrically provided with docking blocks, the number of the docking blocks is at least two and they are distributed in a circular array, and a groove is opened in the middle of the outer side of the docking block.

[0005] The beneficial effects of the utility model are as follows: by providing the pipe pile body, the frame and the docking block, it is convenient for the pipe piles to be docked; by providing the notches, it is convenient for the workers to use the clamps or the binding parts to clip into the notches, so as to achieve the effect of locking the pipe pile connection and effectively ensure the connection strength of the pipe pile connection.

[0006] As a further improvement of the utility model, the technical problem to be solved is: the strength of the internal skeleton of the concrete pipe pile is low, which affects the safety of the concrete pipe pile in use.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the skeleton includes a first support member, a second support member and a fixed ring, the number of the fixed rings is multiple and vertically distributed, the inner surface and outer surface of the fixed ring are symmetrically provided with two first support members, the inner surface and outer surface of the fixed ring are symmetrically provided with two second support members, and the upper and lower ends of the second support members both penetrate into the interior of the docking block.

[0008] The beneficial effect of the above improvement is: by arranging the first support member and the second support member on both the inside and the outside of the fixing ring, the skeleton has high strength and is not easy to deform, and there are multiple connection points between the first support member, the second support member and the fixing ring, which effectively ensures the connection strength of the skeleton.

[0009] The utility model further improves the technical solution adopted as follows: the first support member is composed of a plurality of first vertical ribs, and the plurality of first vertical ribs are respectively connected and fixed to a plurality of fixing rings; the second support member is composed of a plurality of second vertical ribs, and the plurality of second vertical ribs are respectively connected and fixed to a plurality of fixing rings.

[0010] The beneficial effect of the above improvement is that by providing a plurality of first vertical ribs and second vertical ribs, and connecting and fixing them with the fixing ring, the overall strength of the skeleton is effectively guaranteed, thereby ensuring the strength of the pipe pile.

[0011] The utility model further improves the technical solution adopted as follows: the upper and lower ends of the two adjacent first vertical ribs on the inner and outer sides are both sleeved with a first fixing sleeve, the end of the first fixing sleeve is fixedly connected to the surface of the fixing ring, and the upper and lower ends of the two adjacent second vertical ribs on the inner and outer sides are both sleeved with a second fixing sleeve, and the end of the second fixing sleeve is fixedly connected to the surface of the fixing ring.

[0012] The beneficial effect of the above improvement is that by providing the first fixing sleeve and the second fixing sleeve, the inside and outside of the first fixing sleeve and the second fixing sleeve are filled and wrapped with concrete, which plays an effective supporting effect, thereby effectively improving the strength of the end of the pipe pile body.

[0013] The technical solution adopted in the utility model for further improvement is as follows: the outer surfaces of the first fixing sleeve and the second fixing sleeve are not smooth.

[0014] The beneficial effect of the above improvement is: effectively ensuring the connection strength between the surfaces of the first fixing sleeve and the second fixing sleeve and the concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0020] Embodiment 1:

[0021] like Figure 1-3 As shown, a prestressed concrete pipe pile without end plates includes a pipe pile body 1 and a skeleton arranged on the inner wall of the pipe pile body 1. The upper and lower ends of the pipe pile body 1 are symmetrically provided with docking blocks 8. The number of docking blocks 8 is at least two and they are distributed in a ring array. A notch 2 is opened in the middle of the outer side of the docking block 8. By providing the pipe pile body 1, the skeleton and the docking block 8, it is convenient for the pipe piles to be docked. By providing the notch 2, it is convenient for the staff to use the clamp or the binding piece to be inserted into the notch 2 to achieve the effect of locking the pipe pile connection, and effectively ensure the connection strength of the pipe pile connection. During use, the spacing between two adjacent docking blocks 8 is the same as the docking block 8 itself, thereby effectively ensuring that when the pipe piles are docked, the docking block 8 is completely inserted into the gap between the corresponding two docking blocks 8, effectively ensuring the stability of the pipe pile connection.

[0022] The skeleton includes a first support member, a second support member and a fixing ring 3. The fixing ring 3 is multiple and vertically distributed. Two first support members are symmetrically arranged on the inner and outer surfaces of the fixing ring 3. Two second support members are symmetrically arranged on the inner and outer surfaces of the fixing ring 3. The upper and lower ends of the second support members penetrate into the docking block 8. By arranging the first support member and the second support member on both the inner and outer sides of the fixing ring 3, the skeleton has high strength and is not easy to deform. There are multiple connection points between the first support member, the second support member and the fixing ring 3, which effectively ensures the connection strength of the skeleton.

[0023] The first support member is composed of a plurality of first vertical ribs 4, which are respectively connected and fixed to a plurality of fixing rings 3, and the second support member is composed of a plurality of second vertical ribs 5, which are respectively connected and fixed to a plurality of fixing rings 3. By providing a plurality of first vertical ribs 4 and second vertical ribs 5, and connecting and fixing to the fixing rings 3, the strength of the entire skeleton is effectively ensured, thereby ensuring the strength of the pipe pile.

[0024] Embodiment 2:

[0025] Further optimization based on the above embodiment: Figure 1-3As shown, the upper and lower ends of the two adjacent first vertical ribs 4 on the inner and outer sides are sleeved with a first fixing sleeve 6, and the end of the first fixing sleeve 6 is fixedly connected to the surface of the fixing ring 3, and the upper and lower ends of the two adjacent second vertical ribs 5 on the inner and outer sides are sleeved with a second fixing sleeve 7, and the end of the second fixing sleeve 7 is fixedly connected to the surface of the fixing ring 3. By providing the first fixing sleeve 6 and the second fixing sleeve 7, the inside and outside of the first fixing sleeve 6 and the second fixing sleeve 7 are filled and wrapped with concrete, which plays an effective supporting effect, thereby effectively improving the strength of the end of the pipe pile body 1.

[0026] The outer surfaces of the first fixing sleeve 6 and the second fixing sleeve 7 are not smooth, which effectively ensures the connection strength between the surfaces of the first fixing sleeve 6 and the second fixing sleeve 7 and the concrete.
