Prefabricated concrete pile connecting structure

Abstract

The invention discloses a prefabricated concrete pile connecting structure. The prefabricated concrete pile connecting structure comprises an end head plate I, an end head plate II, a positioning inserted rod and a clamping fixing assembly; the positioning inserted rod is installed on the end head plate I, and the clamping fixing assembly is installed on the end head plate II; the clamping fixingassembly comprises a limiting clamp sleeve, a limiting wedge clamp and a bearing spring; the limiting clamp sleeve is provided with a clamp sleeve body and a guiding supporting part, and a guiding sliding groove is formed in the guiding supporting part; a guiding sliding surface is arranged on the side, close to the guiding sliding groove, of the clamp sleeve body, the limiting wedge clamp is arranged in the guiding sliding groove, and the bearing spring sleeves the outer side of the guiding supporting part; and the positioning inserted rod can be inserted into the limiting clamp sleeve, and under the action of the restoring force of the bearing spring, the limiting wedge clamp is connected with the positioning inserted rod in a clamping mode, and the rapid connection of a concrete pile isrealized. The prefabricated concrete pile connecting structure has the advantages of simple structure, convenient assembly of the clamping fixing assembly, easy installation of the clamping fixing assembly and the end plates, and the like.

Description

technical field [0001] The invention relates to a prefabricated concrete pile connection structure. Background technique [0002] With the continuous improvement of construction requirements in the construction industry, the butt joint of precast concrete components is an indispensable process. The traditional concrete uplift pile butt joint method is the hoop form and the mechanical toothing form. Two concrete piles are hooped together by three steel plates on the outside of the concrete pile end plate. This type of concrete pile connection structure requires a thicker end plate, resulting in high cost, complicated production and installation processes, and inconvenient installation. [0003] The mechanical interlocking concrete pile connection structure such as Figure 14 , Figure 15a and Figure 15b As shown, it includes a first end plate 77 and a second end plate 78, the end surface of the first end plate 77 in contact with the concrete is welded with a first containi...

AI Technical Summary

Problems solved by technology

This kind of concrete pile connection structure has the following problems: 1. During the production process of concrete piles, it is necessary to place the engaging parts, springs and fixing parts in different receiving boxes, and weld the receiving boxes on the end plates, resulting in In order to reduce the complexity of the production process, 2. The receiving box is welded on the end plate, so that multiple cavities are formed at the end of the concrete pile, and the cross-sectional area of ​​the concrete at the end of the concrete pile is reduced, reducing the compressive performance of the concrete pile; 3. Since the connection structure is engaged with each other through the teeth, the connection between the two concrete piles is realized. However, through the engagement of the teeth, there will inevitably be a gap between the teeth and the connecting rod, which in turn will cause a gap between the concrete piles. , which reduces the pull-out resistance; 4. The main rib fixing hole and the connecting rod fixing hole (plug through hole) need to be processed on the end plate, and the connecting rod fixing hole (plug through hole) and the main rib fixing hole are on the end plate. are arranged at intervals, thus resulting in a reduction in the strength of the end plate
