Abstract

Ferrule reinforcement for the construction of unidirectional and bidirectional reinforced concrete slabs, in which the reinforcement consists of an upper longitudinal round (1), a lower longitudinal round (2) and a transverse reinforcement formed by elements (3), ( 3 ''), (3 '' ''), U-shaped joining the upper and lower longitudinal rounds. This armor is placed inside two or more pieces that we call support-separator. The shapes of these pieces are as follows: Open trapezoidal (5), open trapezoidal but with the width at its lower base equal to the separation of the lightening elements (5 ''), open rhomboidal (6), closed trapezoidal (7) , closed trapezoidal but with the width at its lower base equal to the separation of the lightening elements (7 '') and closed rhomboid (8).

Description

Ferrule armor for the construction of unidirectional and bidirectional reinforced concrete slabs.

Object of the invention

The present specification refers to a request for an Invention Patent, corresponding to a type of ferrule reinforcement for floor construction unidirectional and bidirectional reinforced concrete that improves noticeably existing ones.

Field of the Invention

This invention has its application in the construction industry and more specifically in the construction of unidirectional and bidirectional slabs.

Background of the invention

The frameworks for the construction of floors Unidirectional and bidirectional reinforced concrete are manufactured for the most part by hand, even in the work itself and therefore they are uneconomic and their quality cannot be to guarantee.

Those manufactured in an industrialized way are they usually do combining the basic armor for the construction of armed joists, with the necessary reinforcements that They are added at the factory or on site.

They need dividers to ensure the steel coating, they must be held during concreting, by its manufacturing method forces the nerve the floor is excessively wide and consume more concrete and its Workshop handling is very laborious and therefore expensive.

Other types of armor that are made by joining the lower armor to traditional stirrups, you can not industrialize and its manipulation on site is very expensive.

The armor described herein memory solves all the problems mentioned above, since It is manufactured industrially with a very economical method and With the quality assured.

Description of the invention

The armor consists of a round longitudinal upper (1), a lower longitudinal round (2) and a transverse reinforcement formed by elements (3), (3 '), (3' '), in U shape joining the upper longitudinal rounds e lower. The U-shaped transverse elements protrude from the lower longitudinal round (2), so that in the part outstanding we can join by welding or any other joining method one or several longitudinal round reinforcement (4) of variable length, determined according to the rules of dimensioning of reinforced concrete.

This armor when used for the construction of unidirectional and bidirectional slabs, it place within two or more pieces that we call stand-separator usually made of steel whose mission is to separate the longitudinal rounds lower (2) formwork and prevent them from moving during concreting The shapes of these pieces are as follows: Trapezoidal open (5), trapezoidal open but with the width in its lower base equal to the separation of the elements lightening (5 '), open rhomboidal (6), closed trapezoidal (7), closed trapezoidal but with the width at its lower base equal to the separation of lightening elements (7 ') and closed rhomboid (8), according to figures (2), (3), (4), (5), (6) and (7). Armor Longitudinal is placed inside each of these pieces as indicates in figures (8), (8 '), (9), (10), (11) and (12), between lightening elements (9) and (9 ').

Description of the drawings

To complement the description that has been performed and for a better understanding of the characteristics of the The present invention is accompanied by the present specification as an integral part of it, a set of planes in which with an illustrative and non-limiting nature, what has been represented next:

Figure number 1.- An elevation is represented longitudinal armor in which it has been numbered with the number (1) the upper longitudinal round, with the number (2) the round longitudinal lower, with the number (3), (3 '), (3' '), the U-shaped transverse elements and with the number (4) the round reinforcement.

Figure number 2.- It is an elevation view of the open trapezoidal separator support numbered with the number (5).

Figure number 3.- It is a view of the open trapezoidal support-separator, but that the width of its lower base (5 ') is equal to the separation between lightening elements (9), (9 ').

Figure number 4.- It is an elevation view of the open and numbered rhomboid separator support with the number (6).

Figure number 5.- It is an elevation view of the closed trapezoidal separator support numbered with the number (7).

Figure number 6.- It is a view of the trapezoidal separator support closed but with the width at its bottom base (7 ') equal to the separation of the lightening elements (9), (9 ').

Figure number 7.- It is a view of the closed rhomboid separator support numbered with the Number 8).

Figure number 8.- It is a view of the longitudinal reinforcement inside the separator support open trapezoidal (5) placed on lightening elements of the slab numbered with the number (9) and (9 ').

Figure number 8 '.- It is an elevation view of the longitudinal reinforcement within the trapezoidal separator support open but with the width of its lower base (5 ') equal to the separation between lightening elements (9), (9 '), placed on the elements lightening of the slab numbered with the numbers (9), (9 ').

Figure number 9.- It is an elevation view of the longitudinal reinforcement within the open rhomboid separator support (6) placed on the lightening elements of the slab numbered with the number (9), (9 ').

Figure number 10.- It is a view of the longitudinal reinforcement inside the separator support closed trapezoidal with the width of its base (7 ') lower, equal to the separation between lightening elements (9 '), placed on the lightening elements of the slab numbered with the number (9), (9 ').

Figure number 11.- It is an elevation view of the longitudinal reinforcement within the closed trapezoidal separator support (7) placed the lightening elements of the slab numbered with the number (9), (9 ').

Figure number 12.- It is an elevation view of the longitudinal reinforcement within the closed rhomboid separator support (8) placed on the lightening elements of the slab numbered with the number (9), (9 ').

Figure number 13.- It is an elevation view of two longitudinal reinforcements within two open trapezoidal support brackets (5) placed on the lightening elements of the floor (9), (9 '), (9``).

Figure number 14.- It is a plan view corresponding to the previous elevation in which it looks like the armor longitudinal penetrates the beam (10) by means of the round ones Longitudinal upper and lower (1), (2).

Preferred Embodiment of the Invention

We will follow the figures (13) and (14) in which an elevation and a plan view of two nerves of a unidirectional slab in which we have represented the open trapezoidal support brackets (5), but we could have used any other support-separator object of this patent. Be it proceeds as follows: the open trapezoidal support brackets (5) supported by lightening pieces (9), (9 ') and then placed inside them the longitudinal reinforcements (1), (2).

If the brackets-separators were closed (7), (7 ') and (8) would be introduced at the ends of the longitudinal reinforcements (1), (2) and the set would be supported in lightening elements (9), (9 ').

Claims (4)
