Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.

Referring to fig. 1 and 2, the utility model provides a formwork removal-free device for foundation preformed holes, which comprises a steel reinforcement framework 1, a dense mesh steel wire mesh, a support frame and the like. The support frame comprises a vertical rod 2, a lower cross rod 3, an upper cross rod 4 and the like, through holes 6 are respectively arranged at two ends of the upper cross rod 4, and bolt holes vertically communicated with the through holes 6 are arranged on the side wall or the end face of the upper cross rod 4; the lower parts of the two upright posts 2 are respectively connected with the two ends of the lower cross rod 3, and the upper parts of the two upright posts 2 are respectively sleeved in through holes 6 at the two ends of the upper cross rod 4 and are tightly contacted with bolts 5 arranged in bolt holes; the upper cross bar and the lower cross bar are arranged in parallel, and the distance between the upper cross bar and the lower cross bar is consistent with the height of the steel reinforcement framework 1; a steel bar framework 1 is clamped between the upper cross rod and the lower cross rod, and the periphery and the bottom surface of the steel bar framework 1 are respectively wrapped with a dense mesh steel wire mesh.

Steel reinforcement framework 1 adopts M12 twisted steel to make, and the mesh of dense mesh wire net is greater than 50 meshes, uses the iron wire to ligature dense mesh wire net on steel reinforcement framework 1, installs after the ligature is firm in the reservation hole position.

During the installation, weld the support frame in the bottom earlier, two pole settings 2 are perpendicular to be set up on the basis, and 2 lower parts of pole setting are passed through sheer pole 3 and are connected, and sheer pole 3 adopts M16 twisted steel, places framework of steel reinforcement 1 that will wrap up fine mesh wire net on sheer pole 3. Then, the upper parts of the two vertical rods 2 respectively penetrate through holes 6 at two ends of the upper cross rod 4, bolts 5 are installed in bolt holes to fix the upper cross rod 4, and the upper cross rod and the lower cross rod are in close contact with the upper end surface and the lower end surface of the steel reinforcement framework 1. The upper cross rod 4 is of a square tube structure, or the middle part of the upper cross rod 4 is provided with M16 threads. The symmetrical central lines of the upper end surface and the lower end surface of the steel reinforcement framework 1 are respectively in the same vertical plane with the upper cross rod and the lower cross rod. Because the steel reinforcement framework 1 is wrapped by the dense mesh steel wire meshes, the friction force between the steel reinforcement framework 1 and the upper and lower cross rods is very large, after the steel reinforcement framework is fixed firmly up and down, the position of the steel reinforcement framework 1 cannot move, and a fixing frame is not required to be added all around.

After pouring is finished, the bolt 5 is loosened, the upper cross rod 4 is taken down, and the operation is simple and the repeated recycling is realized. 1 terminal surface of framework of steel reinforcement is square structure, and the terminal surface size is unanimous with the reservation hole size, and the reservation hole is used for the construction bolt more, is M16, M24, M30 and M36's bolt generally, therefore framework of steel reinforcement batch production, and the construction is simple.

Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and it will be understood that modifications and variations may be made by those skilled in the art without departing from the scope of the invention.
