Rebar reinforcement for reinforced concrete beams which, whilst employing the most advanced state of the technique, introduces novel features which facilitate the automated construction of rebar reinforcements for reinforced concrete beams and the construction and placement in situ of negative reinforcements whilst offering savings on reinforcements for supporting shear stress.
This descriptive fact sheet refers to an application for an invention patent corresponding to rebar reinforcement for reinforced concrete beams which, whist employing the most advanced state of the technique, introduces novel features that facilitate the automated construction of rebar reinforcements for reinforced concrete beams and the construction and placement in situ of negative moments reinforcements whilst offering savings on reinforcements for supporting shear stress.
This invention is to be applied in the construction industry, specifically in the manufacture of rebar reinforcement both for beams and negative moment reinforcement for beams.
As regards the current state of the technique, I refer to patent no. 9500414 and supplementary certificates nos. 9500637 and 9600182 of my invention as well as to the patent application of the author no. P200300069.
The novelty that we introduce here resides in that what in the above-mentioned patent and supplementary certificates are named sub-reinforcements, in this invention are made up of elements similar to those described in the application from the author no. P200300060, specifying, as regards the above-mentioned application, that the Us can be upright or upside down and also adding that the vertical branches of the transversal reinforcement may be in the shape of a C, end in a hook or be rectangular, all for the purpose of improving anchorage.
These transversal reinforcements are placed on a parallel plane to the longitudinal round bars to facilitate welding or joining and they protrude from the top longitudinal round bar to facilitate their construction and improve anchorage.
They also protrude from the bottom longitudinal round bars to be able to join to the transversal reinforcements the positive reinforcement round bars by welding or any other joining method, if so determined by the calculation.
The proposed reinforcement is made up of two or more sub-reinforcements which will be described in the drawings that follow, separated between them by the distance determined by the calculation and at the necessary height, as determined by the calculation for reinforced concrete structures.
The sub-reinforcements are joined together by way of two transversal round bars, a top one and a bottom one, duly separated and joined to the sub-reinforcements by welding or any other joining method, in the shape indicated in the following drawings.
In order to complete the description provided here and for the purpose of a better comprehension of the characteristics of the invention, attached to this descriptive fact sheet, as an inseparable part of it, is a set of illustrative and non-exhaustive plans which represent the following:
In this drawing and without posing any limitation, the sub-reinforcements of the type shown in figure 2 are manufactured in a special machine. In figure 6 we can see that the reinforcement is made up of three sub-reinforcements of the height and with the separation determined by the rules of the calculation.
They are joined together by welding or any other joining method, with the top and bottom horizontal branches of the transversal reinforcement. The top transversal reinforcement may be of the type shown in figures 8, 9 and 10. The bottom horizontal reinforcement may be of the type shown in figures 11, 12 and 13. Subsequently, the reinforcement round bars nos. 19 and 20 are introduced and the round bars for supporting the negative moments nos. 21 and 22 are placed. It is important to point out that these are supported on the top horizontal reinforcement of the transversal reinforcement, facilitating their placement in situ.
We consider it unnecessary to make this description more extensive as any expert in the field will understand the scope of the invention and the advantages that it entails.
The materials, shape, size and positioning of the elements will be subject to variation, provided that this does not alter the essence of the invention.
The terms employed in this descriptive fact sheet should be interpreted in a broad and non-restrictive manner.
