Definitions
- the figures 1 ,2 and 3 show this process and its stages.
- the rods are kept in position by the hangers (4), which may occur at any number, usually according to the structural project, and they are also made of the same steel as the rods are, and they are stuck to the rods by either welding or wire fastening.
- the Figure 3 is a general frontal view of a pillar (5) which is being built and at this stage it is wrapped in a wooden mold (6), whose frontal part has been omitted in order to reveal the inside of the pillar, which will be removed when the concrete that will be placed in its interior is cured.
- the hangers (4) usually have a gauge which is smaller than that of the main ironwork and they are obtained by their own cutting and folding at the proper dimensions and shapes, according to Figure 4, where we can see the hanger from an upper view, here in a rectangular shape; it may take other polygonal shapes, though, such as that of a square, a triangle, a hexagon, etc.
- the raw material offered by the market to be used as rods usually has the specific section (7), showed in the Figure 5, called rounded core rod, and the specific surface (8), showed in the Figure 6, known as corrugated surface. These specific shape and surface are intended to increase the contact area and the adhesion of the rod steel (2) and hangers (4) with the concrete, raising the whole resistance.
- the Figure 8 shows the octagonal profile (10) of the ROD WITH OCTAGONAL CORE PURPOSE-BUILT FOR CIVIL CONSTRUCTION (1) and the Figure 9 shows its specific section (11), derived from its specific corrugated surface.
- the Figure 10 shows the system of the forces applied when folding the rods, from any profile of the section, both manually and industrially: - the rod (2) is placed in the correct position on the folding bolt by the fasteners (12) and (12 A); at this point it gets folded by the action of the force (14).
- the Figure 11 shows, in a frontal view, the results which are obtained; although the expected results are those of the straight defined by the points ABD, in the practice, folds which are distributed statistically by the angles formed by the straights ABC and ABE are obtained, and it is evident that in the formation of a squared-shaped hanger (4), four random dispersions like these are added, so that the hanger (4) does not result in co-planned, with the consequences which were pointed out.
