Abstract

The invention relates to the production of reinforced concrete structures and can be used in the manufacture of reinforcing elements for reinforcement cages and embedded parts. It allows to increase the degree of adhesion of the reinforcing element to the concrete. The reinforcing element contains the rod 1 with an anchor at the end in the form of a package arranged with a gap of round plates 2, which can be of different diameters and with different mutual arrangement. The diameter of the plates is greater than two rod diameters. 1 hp f-ly, 5 ill. 4 4 00 00 and: GG F1 / GC

Description

eleven

The invention relates to the production of precast concrete structures and can be used in the preparation of reinforcement elements for the manufacture of reinforcement cages and fixings.

The purpose of the invention is to increase the degree of adhesion of the reinforcing element to the concrete,

FIG. 1 shows a reinforcing element with an anchor in the form of a package of two round plates, the general view in FIG. 2 is the same, of three plates; on fig. 3 - the same, from plates of different diameters with different mutual arrangement.

The reinforcing element contains a rod 1 with an anchor at the end in the form of a package arranged with a gap of round plates 2, the diameter of which is more than two diameters of the rod. The package can be assembled from plates of different diameters with different relative positions.

The implementation of the diameter of the plates 2 is greater than the diameters of the rod 1 due to the condition of anchoring the rod in concrete. When the diameter of the plates is less than two sterling diameter, there is no resistance of the annular cross-section of the concrete around the rod against shear under the action of pulling forces on the rod.

The reinforcement element works in the following way.

For the manufacture of a reinforcing element a collection of a package of round plates, which can be used as production waste from punching holes in various metal structures. The plate package is connected to the end of a welding rod.

(f

Under the flux layer or by continuous-fusion on special welding machines, the plates are melted, which ensures their connection with each other and with the rod. The special installation of the plates with a gap is not required, since they are thermally deformed during welding, as a result of which a gap is formed between the welded plates. Harvested reinforcing elements are used as components of reinforcement cages or anchor rods of embedded parts of precast concrete structures.

In the manufacture of reinforced concrete structures and concrete penetrates into the gaps between the plates, which improves the anchorage of the reinforcing element. When plates of different diameters are formed, ledges between them are formed, which additionally increases the degree of anchoring.

The degree of adhesion between the reinforcement and the concrete is achieved by a more developed contact surface of the anchor with concrete,
