Abstract

The invention relates to the construction, in particular, can be used in the manufacture of reinforcement cages intended for the reinforcement of the extreme reinforced concrete beams. The essence of the invention: reinforcement cage consists of interconnected upper and lower longitudinal reinforcement, transverse reinforcement, support plate with separate vertical and horizontal rods and support element. The supporting element is made of individual plates or of a bent reinforcing element. Anchor and longitudinal reinforcement are made in the form of separate rods or in the form of a single bent element. 2 hp ff, 8 ill.

Description

J

This invention relates to reinforcement cages designed to reinforce extreme reinforced concrete beams.

Known reinforcement cage reinforced extreme beams, containing the upper and lower longitudinal reinforcement, clamps and brackets along the entire length of the frame, connected by welding with clamps at the top and bottom.

The disadvantage of this solution is the overspending of the reinforcement on the vertical sections of the brackets, directly on the brackets themselves in the middle part of the frame, as well as the increased labor input during the assembly of the frame.

Closest to the invention is the reinforcement cage of an extreme reinforced concrete girder, comprising upper and lower longitudinal reinforcement, transverse reinforcement, support plates with vertical and horizontal anchor rods and a support element.

The disadvantage of such a frame is the increased intensity of metal consumption, the multi-segment assembly and production of various types of individual elements, as well as the installation of lower brackets.

The purpose of the invention is to reduce the metal content and reduce the labor intensity of manufacturing.

The reinforcement cage consists of interconnected upper 1 and lower 2 longitudinal reinforcement, transverse 3 reinforcement, support plate 4 with separate vertical and horizontal 5.6.9 rods and support element 7.8. The supporting element is made of individual plates 7 or of a bent reinforcing element 8. The anchor and longitudinal reinforcement are made in the form of separate rods 5.6 or in the form of a single bent element 9.

In the manufacture of the reinforcement cage, the popgrechnye rods 3 are welded to the longitudinal reinforcement 1 and 2 by resistance welding, forming flat frameworks. The supporting element is made by welding individual plates or bending a separate reinforcing bar so that it has vertical, horizontal and inclined sections. A support element 7.8, vertical 5 and longitudinal 6 rods or a single bent rod element 9 with horizontal and vertical sections are welded to the support plate 4. When mounting the support element 7 from separate plates, the vertical rods 5 are joined by welding with a horizontal section of the support element 7.

Then, horizontal upper rods 1 of flat frames are welded to the vertical and inclined sections of the support element 7.8. Inclined support
