In order to achieve the above object, the utility model adopts the following technical scheme:
a pile foundation reinforcement cage positioning device comprises a positioning plate, back ribs and supporting legs, wherein the positioning plate is square, the center of the positioning plate is a circular through hole which is through from top to bottom, positioning holes are formed in four corners of the positioning plate, the back ribs and the supporting legs are arranged below the positioning plate, the supporting legs are located at the four corners of the positioning plate, positioning through holes are formed in the middles of the back ribs on the four sides of the positioning plate, and positioning steel plates are inserted into the positioning through holes; during operation, at first make the locating hole decide the pile foundation position, hoist and mount afterwards and transfer the steel reinforcement cage to the circular through-hole interior design elevation of locating plate, promote the positioning steel sheet adjustment steel reinforcement cage position to the center at last.
Further, the positioning plate is a steel plate with a width of 240cm, a length of 240cm and a thickness of 1cm, and a circle with an inner diameter of 220cm is cut.
Further, the positioning through holes are rectangles 42cm wide by 1cm thick.
Furthermore, the positioning steel plate is 40cm wide by 50cm long by 1cm thick, and eight insertion holes are formed in the long edge of the positioning steel plate.
Furthermore, two limiting holes matched with the insertion holes are respectively formed above and below the four edges of the positioning plate.
Furthermore, the main material of the back rib and the support legs is 10# channel steel, the height of the support legs is 20cm, and the positioning plate, the back rib and the support legs are connected through welding.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses an use the reinforcing bar head to insert the locating hole and fix the locating plate, and decide the position of pile foundation, provide safe construction platform for the constructor, reduce the potential safety hazard. Traditional pile foundation job site, especially drilling bored concrete pile because on-the-spot unevenness and mire, have great potential safety hazard in the work progress. And the utility model discloses, not only can effectual positioning reinforcement cage center, still can be for transferring reinforcement cage and pile foundation and filling the construction platform that provides the safety and stability. The steel reinforcement cage is processed for the merogenesis, transports to and carries out the hoist and mount concatenation after the scene, and at the in-process of concatenation, the locating plate has just played the effect of support steel reinforcement cage.
2. The utility model discloses a position of pile foundation is decided out to the locating hole, and pile foundation steel reinforcement cage location accuracy has been improved to the position to the center of rethread positioning steel sheet adjustment steel reinforcement cage. The conventional pile foundation reinforcement cage has errors in positioning, the center deviation can exceed the design and specification values, the post rework cost is high, and the construction period is delayed. However the utility model discloses can transfer the back at the steel reinforcement cage according to the quick accurate determination pile foundation center in stake footpath, avoid the later stage because of the rework that the pile foundation off normal caused, ensure that the pile foundation construction progress is not influenced.
