Implementation method of steel frame forming device for pile hole foundation

Abstract

The invention discloses an implementation method of a reinforcement cage forming device for a pile hole foundation. The method includes: fixing a plurality of fixing components on a first rotary discand a second rotary disc to form two concentric and unidiameter circles; regulating the interval between a first support plate and a second support plate according to the axial length of a reinforcement cage, inserting a plurality of longitudinal reinforcing steel bars needed by the reinforcement cage into the fixing components on butt joint holes and mounting holes; starting a motor to allow themotor to drive a gear to mesh with a toothed belt, and allowing the second rotary disc to rotate inside two bearings, and allowing the first rotary disc to rotate synchronously; arranging transverse reinforcing steel bars on the reinforcement cage structure formed by the longitudinal reinforcing steel bars, and welding the connecting points of the transverse reinforcing steel bars and the longitudinal reinforcing steel bars until the transverse reinforcing steel bars completely wind the reinforcement cage structure. The method has the advantages that during the winding, the longitudinal reinforcing steel bars are constantly clamped and fixed by the fixing components, and the welding effect between the longitudinal reinforcing steel bars and the transverse reinforcing steel bars is prevented from being affected by the fact that the longitudinal reinforcing steel bars turn in barrels.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an implementation method of a steel bar skeleton forming device for a pile hole foundation. Background technique [0002] During the construction of bridges, culverts or high-rise buildings, the foundation may be piled according to requirements. The method is to use machine punching and water mill drilling, and the hole depth meets the design requirements, and then lower the reinforcement cage to the pile hole, and then insert the conduit for concrete pouring . And when the concrete structure is a columnar or strip-shaped member, the central part does not need to be reinforced, and only the reinforcement is arranged under the surface of the concrete member that contacts the air. If the component is independent, it is necessary to prefabricate the reinforcement around the component during construction, and usually the prefabricated reinforcement structures such as bored piles...

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; however, since there are many longitudinal bars on the steel cage and they are distributed in a circle, that is, each longitudinal bar needs to be fixed one by one during production to complete the horizontal alignment. Helical winding and welding of ribs; however, the existing fixing parts tend to move relative to the longitudinal ribs when the horizontal ribs are wound, which leads to uneven distribution of the transverse ribs and unsatisfactory welding effect of the transverse ribs. Moreover, when the steel cage is hoisted , the transverse reinforcement is easy to separate from the longitudinal reinforcement, and eventually the strength of the pile hole after pouring cannot meet the construction requirements
