Cement precast pile connecting piece

Abstract

The invention relates to the field of precast pile installation, in particular to a cement precast pile connecting piece which comprises a fixing mechanism, a reinforcing mechanism, a linkage mechanism and a joining mechanism. Each penetrating through hole is composed of two intersecting through holes, the steel bars of the precast piles at the upper end and the lower end are inserted into the same penetrating through hole, the two steel bars do not abut against each other or interfere with each other and are provided with coincident parts, and therefore the strength of the connecting position is enhanced. The poured cement is guided into the penetrating through holes through the pouring straightway and the pouring channel, so that the reinforcing steel bars inserted into the penetrating through holes are subjected to cement fixation; when the limiting sliding rod moves in the penetrating through hole direction, the reinforcing hammer head extrudes the reinforcing steel bar inserted into the reinforcing hammer head to the side wall, so that the reinforcing steel bar is fixed, and the connection stability is enhanced; all the components of the reinforcing mechanism are connected through the linkage mechanism, so that all the components of the reinforcing mechanism are synchronized, and the situation that the reinforcing mechanism cannot achieve the reinforcing function due to the fact that a single component does not work is prevented.

Description

technical field [0001] The invention relates to the field of prefabricated pile installation, in particular to a cement prefabricated pile connector. Background technique [0002] Precast cement piles are referred to as prefabricated piles, which are suitable for foundation treatment such as silt, muddy soil, cohesive soil, silt, sandy soil and artificial filling. Due to reasons such as production, transportation and construction, the pile length of precast concrete pipe piles has certain restrictions. Generally, it should not exceed 15m. It is difficult to design the pile length required to meet the bearing capacity of the building at one time. Therefore, piles need to be connected on site during pile driving. [0003] The existing prefabricated pile connection methods generally adopt two methods of manual welding and mechanical joints, most of which are based on the welding method. However, the existing prefabricated pile connection methods often have problems such as ins...

AI Technical Summary

Problems solved by technology

However, the existing prefabricated pile connection methods often have problems such as insufficient connection strength of the steel skeleton at the connection part, and the joints of the steel bars are easy to break. At the same time, a single connection method is used between the connection parts, which will lead to unreliable connection and insufficient connection strength.
