The invention relates to the elements of the wall-mounted spatial reinforced concrete structures, can be used in the reinforcement of the envelopes of the coatings of buildings and is an improvement in the design of the main ed. St. 1283326.

The purpose of the invention is to provide the possibility of reinforcing spatial casings with ruled surfaces.

FIG. 1 shows the reinforcement cage, a general view; in fig. 2 - part of the frame with a zigzag rod unfolded; on ; FIG. 3 shows section A-A in FIG. 2

The reinforcement cage contains longitudinal; which valve 1 is oriented in the direction of the line-forming elements; the surfaces of the sheath 2. The reinforcement 1 has bent rods 3, straight-line sections 4 and 5, which are alternately arranged across and with a slope: to the reinforcement 1, and the bends 6 are radially; bore not less than two of their diameters and the bend vertex goes over the axis of the longitudinal reinforcement; Tours 1 are from one to three rounding radii, with the bends of the adjacent GB of the rods combined with each other.

A part of the zigzag rods 7 are made deployed about an axis parallel to the longitudinal reinforcement 1, and are arranged alternately between un-rotated rods 3.

To reinforce the sheath with a ruled surface, first make a flat

These sections are made of welded between the longitudinal reinforcement 1 and zigzag rods 3. Then these sections are placed on the casing with the orientation of the longitudinal reinforcement 1 in the direction of the ruled surface forming it. The sections are laid with a gap between each other, zigzag rods 7 are placed on them, successively being welded from the bends to the reinforcement 1 of the adjacent sections. At the same time, the rods 7 are deformed in length to successively align their bends with the longitudinal reinforcement 1, as a result of which these rods become deployed relative to an axis parallel to the reinforcement. After laying and fixing all the unrolled rods 7, the reinforcement cage acquires a curvilinear shape corresponding to the shape of the shell surface.
