Installation position control of pile foundation reinforcement cage and concrete pouring construction platform

Abstract

The invention provides a pile foundation reinforcement cage installation position control device and a concrete pouring construction platform. The reinforcement cage installation position control device comprises a reinforcing bar connecting rod and a centering adjusting steel pipe. The bottom of the reinforcing bar connecting rod is connected with the top of a reinforcement cage. Working groovesare formed in the two ends of the centering adjusting steel pipe. The reinforcing bar connecting rod penetrates through the working grooves. The two ends of the centering adjusting steel pipe abut against the inner wall of a guard cylinder. The concrete pouring construction platform is located on the ground and located above the reinforcement cage installation position control device. A reinforcing bar connecting rod hole is reserved in the concrete pouring construction platform. The top of the reinforcing bar connecting rod is arranged in the reserved reinforcing bar connecting rod hole in apenetrating mode and fixed. The pile foundation reinforcement cage installation position control device has high practicability, the reinforcing bar connecting rod and the centering adjusting steel pipe can be reused, the position of the reinforcement cage can be effectively controlled, and meanwhile, the concrete pouring construction platform can effectively prevent guide pipe displacement in theconcrete pouring process.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a position control for installation of a reinforced cage of a bored pile and a fixed platform for combined construction of concrete pouring. Background technique [0002] At present, the installation elevation control of most bored pile reinforcement cages adopts the measurement of the length of the hanging bar (the length is the difference between the ground elevation and the design elevation of the reinforcement cage) to control the installation elevation. The disadvantages of this method are: [0003] ①In the process of concrete pouring, it is easy to cause the steel cage to float up, and the elevation deviation of the steel cage is too large; the connection between the hanging bar and the steel cage is usually welded, which often causes the cage to fall due to welding quality problems, and the welding speed is slow; ②Usually the hanging bar and the steel bar Ca...

Problems solved by technology

[0003] ①In the process of concrete pouring, it is easy to cause the steel cage to float up, and the elevation deviation of the steel cage is too large; the connection between the hanging bar and the steel cage is usually welded, which often causes the cage to fall due to welding quality problems, and the welding speed is slow; ②Usually the hanging bar and the steel bar Cages cannot be reused after welding, resulting in waste of materials; ③There are no other guarantee measures after the reinforcement cages are centered. The conventional platform is easy to disturb the position of the reinforcement cages during the pouring process. At the same time, the displacement of the conduits is very common, which is likely to cause displacement of the reinforcement cages and jamming of the conduits ; ④ Conventional use of mud hole pile foundation site is wet and slippery, low safety factor
