A prefabricated columnar steel frame structure for high-rise building construction

Abstract

The invention discloses a columnar steel bar framework prefabricating device for high-rise building construction. The columnar steel bar framework prefabricating device for high-rise building construction comprises a base; a guide rail is arranged on the middle portion of the base; a first supporting plate is fixed to one end of the guide rail; a second supporting plate is arranged at the other end of the guide rail in a sliding manner; a first rotating disk is rotationally arranged on the first supporting plate, and is provided with a plurality of butt joint holes; two coaxial bearings are rotationally arranged on the second supporting plate, and a gap is reserved between the two bearings; a second rotating disk opposite to the first rotating disk is rotationally arranged in the two bearings; a tooth belt is arranged on the middle portion of the peripheral wall of the outer circle of the second rotating disk; a motor is fixed to the second supporting plate; a gear is installed at theoutput end of the motor; a plurality of fixing holes are formed in the second rotating disk; and a plurality of fixing assemblies are further included. In the winding process, longitudinal steel barsare clamped and fixed by the fixing assemblies all the time, and it is avoided that the longitudinal steel bars overturn in a barrel body, and consequently the welding effect between the longitudinalsteel bars and transverse steel bars is affected, so that the strength of a steel bar cage can be guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated columnar steel frame structure for high-rise building construction. 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, excava...

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
