Description

Ferrule reinforcement for concrete beams armed.

Object of the invention

The present specification refers to an invention patent application corresponding to a iron reinforcement for reinforced concrete beams, which collecting the most advanced state of the art introduces new features that facilitate the automated construction of ferralle armor of reinforced concrete beams, construction and placement in work of negative armor and saving on armor To withstand the shear stress.

Field of the Invention

This invention has its application within the construction industry, in terms of manufacturing iron reinforcement for both beams and beams negatives it means.

Background of the invention

On the state of the art I refer to the Patent No. 9500414 and to Certificates of Addition No. 9500637 and 9600182 of my invention as well as the patent application of the own author P200300069.

The novelty that we introduce is that which in the previous patent and certificates of addition are called as sub-armor, in this one, they are formed by elements similar to those described in the application itself author P200300060, specifying with respect to the latter that the U-es can be upside down or upside down and adding that the vertical branches of the transverse reinforcement they can be C-shaped, end in a hook or be shaped rectangle, all of the above to improve your anchor.

These transverse reinforcements are placed in a parallel plane to the longitudinal rounds to facilitate the welding or joining them and protruding from the longitudinal round superior, to facilitate its construction and improve its anchorage.

They also stand out from the round ones lower longitudinal, to be able to join them by welding or any other method of joining the reinforcement rounds of positive, if the calculation so determines.

Description of the invention

The proposed armor is formed by two or more sub-armor than we will describe in the drawings that come next, separated the distance from each other that the calculation determines and of the necessary height, also determined by the calculation of reinforced concrete structures.

The sub-armors are joined between yes by means of two transverse rounds, one upper and the other bottom conveniently separated, attached to the sub-armor by welding or any other method of union and with the form indicated in the drawings that follow continuation.

Figure 5.- Shows an elevation view of a sub-armor composed of a round upper longitudinal 1, a lower longitudinal round 2 and a succession of rectangles with the number 3, 3 'and 3' 'attached to the longitudinal upper and lower round, by welding or any other joining method, which form the armor for resist shear stress.

Figure 6.- Shows a sectional view of the reinforcement for ferralla beams that is proposed formed in this case for three sub-armor like those in the figure 2, but that with the same purpose could be formed with those of the Figures 3, 4 and 5, and be two, four or the number of sub-armor that the calculation determines. With the numbers 10, 11 and 12 are designated the longitudinal rounds superior, with the numbers 13, 14 and 15 are called the rounds lower longitudinal. The numbers 16, 16 ', 16' 'correspond to  the stirrups in the form of U-es. The number 17 designates the upper horizontal transverse reinforcement that can be like the Figures 8, 9 and 10 which in this case for clarity in the drawing is represented as figure 8. The number 18 corresponds to the lower horizontal transverse reinforcement that can have the shape of figures 11 or 12 and 13; in this case and for reasons of clarity It has been drawn as Figure 11. The numbers 19 and 20 designate the round bottom reinforcement and numbers 21 and 22 represent the rounds that resist negative moments, which can be seen are placed on the upper transverse reinforcement 17, without need for this armor to be a broken line.

Preferred Embodiment of the Invention

Sub-armor is manufactured, in this drawing and without any limitation, of the type of  Figure 2, in a special machine. Following figure 6, we see that the armor is formed with three sub-armor of the height and with the separation that the rules of the calculation determine.

They are joined together by welding or any other joining means, with the upper and lower horizontal branches, of the transverse armor. The upper transverse reinforcement can be of the type of fig. 8, 9 or 10. The lower horizontal armor it may be of the type of figures 11, 12 or 13. Subsequently, it introduce the reinforcement rounds 19 and 20 and place the round to resist negative moments 21 and 22. It is important to note that they rely on horizontal armor upper of the transverse reinforcement, facilitating its placement in work.

It is not considered necessary to make more extensive this description so that any subject matter expert understands the scope of the invention and the advantages thereof drift

The materials, shape, size and layout of the elements will be susceptible to variation, as long as this does not imply an alteration to the essentiality of the invention.

The terms in which this report has been described they should always be taken broadly and not limitative.
