Description
Technical Field
The utility model relates to the technical field of installation of bored pile reinforcement cages, in particular to a temporary fixing and centering tool for pile foundation reinforcement cages.
Background
Along with the rapid development of urban economy, the bored pile foundation is widely applied to house construction and bridge engineering.
The bored concrete pile has one and surpasss and irritates the height in the construction, and when the steel reinforcement cage was installed one section at the top, the job site can adopt two hanging bars to put down the steel reinforcement cage in place, because of hanging bars are few, and overall rigidity is little. The concrete protection layer thickness of the cast-in-place pile reinforcement cage is deviated due to the fact that the installation center point of the reinforcement cage is not coincident with the center of the pile casing, the concrete casting vibration, tube drawing and other factors are affected, the phenomenon that the concrete protection layer thickness is too much and too little exists, the rib exposing phenomenon can occur seriously, and the service life of the pile is affected. Meanwhile, the problems that the thickness of the protective layer is insufficient and the exposed part of the rib needs to be treated again occur, so that manpower is wasted seriously, the construction cost is increased, and the construction period is delayed.
Disclosure of Invention
The utility model is developed aiming at the problems in the prior art, and provides a temporary fixing and centering tool for a pile foundation reinforcement cage, which can ensure that the reinforcement cage coincides with the center of a pile casing when being installed, does not generate displacement in the concrete pouring process, can be reused, and has the advantages of simple operation and strong practicability.
The utility model is realized by the following technical scheme: the temporary fixing and centering tool for the pile foundation reinforcement cage comprises a reinforcement cage, wherein a plurality of hanging ribs are arranged at the upper end of the reinforcement cage, all the hanging ribs are connected through reinforcing ribs, a pile casing is arranged outside the reinforcement cage, and the temporary centering tool is clamped on the pile casing; it is characterized in that the method comprises the steps of,
the temporary centering tool comprises an outer ring fixing frame, an inner ring fixing ring, stiffening ribs and turnbuckle screws, wherein the outer ring fixing frame is clamped and fixed around the protective cylinder, the inner ring fixing ring is arranged in the outer ring fixing frame and connected with the outer ring fixing frame through a plurality of stiffening ribs, the turnbuckle screws are further arranged on the inner side of the outer ring fixing frame, one ends of the turnbuckle screws are arranged on the outer ring fixing frame, and the other ends of the turnbuckle screws are connected with hanging ribs through hanging hooks.
Preferably, the number of the hanging ribs is 4, and the hanging ribs are distributed in a circumferential array along the reinforcement cage.
Preferably, the inner ring fixing ring passes through screw cabins of all turnbuckle screws.
Preferably, the upper end of the reinforcement cage is also penetrated with a steel rod.
The beneficial effects of the utility model are as follows: the tool ensures that the reinforcement cage does not generate displacement in the processes of subsequent pipe descending, concrete pouring and pipe pulling, and the thickness of the reinforcement cage concrete protection layer is effectively controlled.
The tool is simple to operate and can be reused.
