Description

(54) ARMATURE ELEMENT

one

The invention relates to reinforcement elements used to make reinforcement cages for reinforced concrete products and structures.

Reinforcing element on the main ed. swith No. 697666 contains a curved metal rod, while the places of bends of the metal rod are made in the form of loops 1.

The disadvantage of this reinforcing element is the flat construction of its contour, which creates the need for preparing a plurality of such elements and increases the laboriousness of manufacturing reinforcing cages.

The purpose of the invention is to reduce the labor intensity of the manufacture of reinforcement cages.

For this, in the reinforcing element, the metal rod is made with bends in the planes perpendicular to the planes of the loops, with the formation of a spatial broken contour.

FIG. 1 shows the reinforcing element in the extended position, side view; in fig. 2 - the same, in a compressed position; in fig. 3 and 4 - embodiments of the contour of the element in the plan; in fig. 5 is a reinforcing element with additional loops on the straight sections of the rod, side view; in fig. 6 - the same plan view; in fig. 7 - reinforcing element with different

5 form sections of a broken contour, side view; in fig. 8 - the same plan view; in fig. 9 shows an embodiment of the element of FIG. 7, in plan; in fig. 10 is an example of the placement of a reinforcing element in a frame of a cylindrical reinforced concrete slab.

 vault; in fig. 11 - MCC same for a reinforced concrete element such as a beam; in fig. 12 is a view A of FIG. eleven; in fig. 13 is a view B in FIG. eleven.

The reinforcing element is a 5 curved metal rod 1 with bends made in planes perpendicular to the planes of the loops 2, with the formation of a spatial broken contour of various shapes. On the straight sections of the rod there may be additional loops 3.

The reinforcing element is made by continuously winding the wire on the auxiliary rods fixedly fixed or with the possibility of longitudinal movement, the diameter of which is somewhat larger than the diameter of the longitudinal reinforcing rods installed in the holes of the hinges 2 in the manufacture of the reinforcement cage. Smooth or corrugated wire can be used to make the reinforcement.

To assemble the reinforcing element into the reinforcement cage, it is stretched, and then longitudinal reinforcing bars (not shown) are installed into the holes in the loops 2. It is also possible to first install the longitudinal bars and then stretch the reinforcing element on these bars. Thereafter, spacers are installed between the rods or the longitudinal rods are interconnected in several places with a hot wire to fix the loops 2 of the reinforcing element on the longitudinal rods of the frame.
