Background
The anchoring steel bar in the existing mechanical connection prestressed concrete bamboo joint pile adopts a hot heading and thread rolling method, and the method has the following problems:
1. the implementation is difficult. In practical application, the method is difficult to realize, and particularly, the processing difficulty is extremely high when the small steel bar (diameter 16) is connected with the large nut (diameter 30). And tempering is needed after upsetting, otherwise, the structure is not uniform, the stress is large, and the tooth and the wire are easy to break. If the diameter of the upset head is not enough or the roundness is not enough, the quality of the processed thread is directly influenced, and the connection quality is unreliable.
2. The cost is high. The length of each steel bar needing upsetting is more than 1.0m, and the processing cost is high due to difficult implementation. Moreover, when the machine is processed on the construction site, the automation degree of the equipment for upsetting, tempering and thread rolling arranged on the site is low, and the cost of processing personnel is high. If the components are sent to a factory for processing, the weight of the components is heavy, and the cost of transportation back and forth is high.

Drawings
Fig. 1 is a schematic structural view of a first embodiment of the mechanical connecting buckle for connecting the pile top and the bearing platform of the bamboo joint pile of the present invention;
fig. 2 is a schematic structural view of a second embodiment of the mechanical connecting buckle for connecting the pile top of the bamboo joint pile and the bearing platform.
Detailed Description
The present invention will be described in further detail with reference to the following description of the drawings.
As shown in fig. 1, the mechanical connecting buckle for connecting the pile top of the bamboo pile with the bearing platform comprises a connecting buckle body 1, wherein a first thread portion 11 is arranged on the outer wall of the connecting buckle body 1, a second thread portion 12 is arranged in the connecting buckle body 1, the first thread portion 11 is in threaded fit with a nut 2 arranged in the bamboo pile, and the second thread portion 12 is in threaded fit with an anchoring steel bar 3 extending into the bearing platform.
The connecting buckle body 1 is internally provided with a mounting hole in an excavating way, the mounting hole and the connecting buckle body 1 are coaxially arranged, and the inner wall of the mounting hole can be integrally formed with a second thread part 12.
The mounting hole is through-hole 4, and the whole integrated into one piece of through-hole 4 inner wall has second screw thread portion 12, and the whole integrated into one piece of connector 1 outer wall is equipped with first screw thread portion 11.
As shown in fig. 2, the installation hole is a blind hole 5, a second threaded portion 12 is integrally formed on the inner wall of the blind hole 5, and a first threaded portion 11 is integrally formed on the outer wall of the connecting buckle body 1 near the end where the blind hole 5 is not located.
The end of the anchoring bar 3 is directly provided with a screw thread portion screw-engaged with the second screw thread portion 12 by thread rolling.
The first threaded portion 11 is chamfered near the inner and outer ends of the blind hole 5. This prevents stress concentration, and improves the strength of 1.
The diameter of the first threaded portion 11 is larger than the diameter of the second threaded portion 12. From this, first screw portion 11 can with the 2 screw-thread fit of direct great nuts, second screw portion 12 can with the 3 screw-thread fit of the less anchor reinforcing bar of diameter, need not to adopt the thread rolling behind the hot heading with anchor reinforcing bar 3, can directly thread rolling form the screw thread, reduce the cost of labor, improve the efficiency of construction, easy operation.
For convenience of construction, the thread of the steel bar 3 is processed by a processing machine for processing straight thread connection on a construction site, and the thread processing requirement is the same as that of the common straight thread steel bar (the thread pitch is 2.5mm, and the thread angle is 75 degrees).
The inner teeth 12 are the same as the inner teeth of the common straight thread steel bar sleeve in processing (the tooth pitch is 2.5mm, and the tooth angle is 75 degrees).
The external teeth 11 are matched with the screw teeth of the nut 2 on the bamboo joint pile, and standard screw teeth (the tooth pitch is 2.0mm, and the tooth angle is 60 degrees) are adopted.
To sum up, the utility model discloses utilize reinforcing bar straight thread connection technique, make straight thread at the tip system of the anchor reinforcing bar of hot rolling ribbed, utilize the nut on connector link body butt joint anchor reinforcing bar and the cushion cap tubular column of in-band screw thread and external screw thread, reach transmission reinforcing bar pulling force and pressure, have joint strength height, easy operation, on-the-spot connection speed are fast, production efficiency is high, prefabricate in advance and do not account for time limit for a project, with low costs, environmental protection safety advantage such as not influenced by environment and weather.
