A steel bar connection assembly for bearing pile construction of high-rise buildings

Abstract

The invention discloses a steel bar connection component for construction of high-rise building bearing piles. The steel bar connection component comprises a connection cylinder and a snap ring. A nutis arranged on the connection cylinder. A sliding groove and a limiting groove communicated with the sliding groove are formed in the outer circumferential wall of the connection cylinder. An annulargroove is formed in the bottom of the sliding groove. A through hole is formed in the annular groove. The inner side wall of a press block is flush with the inner circumferential wall of the connection cylinder. The outer side wall of the press block is protruded on the outer end wall of the through hole and disposed in the annular groove. Threads are arranged at the bottom of the sliding groove.A press ring is arranged in the sliding groove in a sleeved mode. A protrusion is arranged on the inner circumferential wall of the press ring. The inner diameter of the protrusion increases gradually from one end, where the press ring is located, to the direction close to the connection cylinder along the axis of the connection cylinder. A contact block is arranged on the outer side wall of thepress block. One end of the connection cylinder is fixed to a rotating disc, and the other end of the connection cylinder clamps and fastens a main rib, so that the main rib is prevented from overturning in the connection cylinder to influence the welding effect between the main rib and transverse ribs, and the strength of a reinforcement cage is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a steel bar connection assembly for high-rise building bearing pile construction. Background technique [0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile (referred to as a cap) or a single pile foundation connected by a column and a pile foundation, referred to as a pile foundation. When the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; when the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation; and construction piles The foundation is usually a low cap pile foundation. In the construction of bridges and culverts or high-rise buildings, low cap piles will be used. The construction process is to use machine punching and water mill drilling, and the hole...

AI Technical Summary

Problems solved by technology

[0003] According to the depth of the pile hole, the axial length of the general steel cage is the same as the depth of the pile hole. However, when pouring a pile hole with a relatively long depth, the construction personnel usually splice multiple steel cages of equal length, and then hoist them to In the pile hole, concrete is poured at the end to shorten the construction time; when the existing connecting piece is hoisted in the steel cage, the two steel cages after splicing are prone to detachment at the joint, which leads to lowering into the pile hole The reinforcement cages of the piles are separated from each other, which eventually leads to the fact that the strength of the pile holes after pouring cannot meet the construction requirements
