Problems solved by technology

[0003] In addition, in the actual use process, the concrete shape will also encounter the situation of continuous connection, for example, it is necessary to connect concrete piles or connect other concrete structures, but the connection will often be damaged, and it is easy to break if the strength is not enough; When continuing to connect, it is necessary to continue to connect steel bars on it. In the prior art, welding is often used for fixing, but welding also has certain defects, such as welding defects, corrosion and other reasons, which are easy to produce in the welding place. fracture

Embodiment

[0044] Such as Figure 1 to Figure 4 As shown, the present invention provides a prefabricated concrete pile, including a skeleton layer and a concrete layer 06, and the skeleton layer includes several steel bars 08 uniformly distributed along the circumferential direction, several first annular bodies 091 uniformly distributed along the axial direction and several A second ring body 092 uniformly distributed along the axial direction;

[0045] The first ring body 091 is wrapped on the steel bar 08, and the steel bar 08 is wrapped on the second ring body 092, and the inclination direction of the first ring body 091 and the second ring body 092 is opposite (as image 3 As shown, one is tilted to the left and one is tilted to the right); that is, as figure 2 As shown, the first ring body 091 is wrapped on the ring-shaped outer ring formed by the steel bar 08 and fixed to it to form multiple fixed points, while the second ring body 092 is embedded in the ring-shaped inner ring for...

Abstract

The invention discloses a precast concrete pile. The precast concrete pile comprises a framework layer and a concrete layer, and the framework layer comprises a plurality of reinforcing steel bars evenly distributed in the circumferential direction, a plurality of first ring bodies evenly distributed in the axial direction and a plurality of second ring bodies evenly distributed in the axial direction; the first ring bodies are wrapped on the reinforcing steel bars, the reinforcing steel bars are wrapped on the second ring bodies, and the inclination direction of the first ring bodies is opposite to that of the second ring bodies. The structure of the internal reinforcing steel bars is optimized, so that the reinforcing steel bars obtain better three-dimensional supporting performance, and then the strength of the concrete pile is improved; and meanwhile, the external reinforcing steel bars and the reinforcing steel bars in the pile body can be effectively connected through the connecting structure, then the fixing defect existing in a welding mode is overcome, the connection strength is greatly improved, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to a prefabricated concrete pile. Background technique [0002] With the continuous development of prefabricated buildings, the use of prefabricated concrete slabs, concrete piles and other prefabricated parts is becoming more and more extensive; for prefabricated piles, there are two main factors affecting their strength, one is the concrete itself, the other One is the steel bars in the concrete, so the distribution structure of the steel bars plays a very important role in the concrete pile; [0003] In addition, in the actual use process, the concrete shape will also encounter the situation of continuous connection, for example, it is necessary to connect concrete piles or connect other concrete structures, but the connection will often be damaged, and it is easy to break if the strength is not enough; When continuing to connect, it is necessary to continue to connect st...
