Abstract

Security fixing of enclosures between concrete pillars. The present invention refers to the security fixing of enclosures between pillars or concrete walls through the use of sheaths and rods that, once embedded in the concrete of said pillars or walls, are intended to prevent the brick and mortar enclosures from as a consequence of seismic movements, explosions, implosions, wind currents, or any foreign agent that endangers the enclosures by putting pressure on them, they collapse. Fixation that is carried out through the use of sheaths and rods. The pods remain embedded in the concrete. And they consist of holes to screw the rods, thus leaving the set ready for use.

Description

Fixing security of enclosures between concrete pillars

Object of the invention

The present invention relates to fixing of security of enclosures between pillars or concrete walls through the use of COWS and RODS that once embedded in the concrete of said pillars or walls, have the purpose of prevent what brick and mortar enclosures like consequence of seismic movements, explosions, implosions, wind currents, or any strange agent that endangers the enclosures when pressing on them, unfold. Known to all, they are the damages that cause the enclosures (walls) when as a result of one of the agents expressed collapse into emptiness sowing death, crushing, and ultimately destruction. With the present invention it is not aims to prevent the fall of all the bricks and mortar, but if a large part of it, justifying it its purpose

Background of the invention and state of the art

The invention is in the field of construction and more specifically in the structures of buildings

As is known the walls and enclosures of the buildings, are basically made up of bricks and mortar (mortar) for fixing to the different beams and pillars. Sayings enclosures, having no more fixation than the mortar, which although it seems at first that it was fixed enough, it fails over time, which causes the appearance of cracks in the junction point of the bricks and mortar with the pillars or even that the pillars remain and that the bricks fall to the street, or at best inside the houses.

At present, although the system is known of introducing plastic or other material plugs, in holes previously practiced on the pillars, however, this system It is dangerous for the worker who is responsible for making drills necessary to then introduce the rods that serve as reinforcement.

From what is known by the applicant to date There is nothing similar that solves the crash problem of enclosures with such efficiency, speed of installation, and cost so small, significantly improving everything about the particular is currently known and used.

Description of the invention

"Fixing security of enclosures between concrete pillars ", which the invention proposes, resolves in a fully satisfactory way the problem previously exposed.

This system eliminates the risks to the  Operator and gains efficiency because its installation is finished when removing the formwork, pending only to screw LAS RODS and ready to lay the brick course.

Fixing security of enclosures between Concrete pillars are made by using pods and rods, as well as screws to fix said sheaths to the formwork plates, through the drills that are made in the plates, as many as pods are required, in said holes the screw is inserted and the other end (inside) is fixed the sheath and is ready to move to the formwork assembly.

The advantage of the invention is based on the simplicity of the installation of the sheaths on the plates for formwork, since you just have to screw them to them and unscrew them once the concrete has set, leaving it so the pods submerged in the concrete and flush with it.

The pods are fixed to the formwork plates with two screws with very few threads, as said Screws are only necessary to fix the pods until Forge the concrete. Once set, the screw that is removed fix THE HOOD and we have the reinforcement installed, as many as the construction, 1, 2, 3 per meter of pillar or enclosure.

The pods can be of different sizes in function of the needs and the number of SHEETS used per square meter to support the bricks and mortar.

LAS VARILLAS, which are threaded in LAS VAINAS a once the pillars or supports have been removed, they remain between the mortar and bricks, may have the necessary length to join with the opposite rod. The length of LAS VARILLAS is variable according to needs.

THE SHEETS, are made of steel with the necessary measures, according to the effort to which they will be subjected.  They consist of a piece of steel of variable size, with a drill threaded longitudinal center to be able to thread LA VARILLA, and by the Inside the sheath, some channels, circular and longitudinal, to prevent it from escaping concrete. COWS can have a round, square, rectangular shape without affecting the good operation of the set, this variation of forms refers, to the size and shape by virtue of the pressure they must withstand.

Description of a preferred embodiment

As shown in Figure 1, you can appreciate that the sheath (1) externally has channels or circular and longitudinal grooves (2), to prevent can escape from the concrete or turn by screwing the rod (7). It can also be seen that said sheath is equipped with a widen (3) in the form of a washer for better support and an internal thread (4) intended to fix the rod (7).

The sheath (1) can have the shape that work require, as seen in figures 3,4 and 5, since this form does not affect the essence of the invention.

In figure 2, it can be seen that the rod (7), it has a thread (5), intended to fix said rod in the sheath (1) and a recess (6) to be able to securely tighten the rod (7) in the sheath (1).

Figure 6 shows a screw, for fix the sheath (1) to the formwork plate, which is equipped of a thread (8) equal to that of the sheath (1) and of a handle (9) in the form of a pallet, for faster work.

The whole assembly is shown in Figure 7 working. Said set is formed by pillars or walls of concrete (11); pods (1) embedded in concrete and rods (7) with its threads (5) screwed into the sheaths (1) and with the recesses (6) intended to introduce a key to tighten the rods (7) when introducing these into the internal threads (4) of the pods (1). The rods (7) can be provided with the length necessary (10) until it is in the center of the enclosure, to greater resistance. The rods (7) can also be smaller length, for cases of lower resistance.

Claims (5)

1. Security fixing of enclosures between concrete pillars, which being those used to reinforce brick and mortar enclosures through their concrete supports, is characterized by using sheaths (1) embedded in the concrete and fixed to the plates of formwork, by means of screws until the setting of the concrete. 2. Fixing security of enclosures between concrete pillars, according to the preceding claim, it is characterized in that the sheaths (1) have channels (2) along their shape to prevent rotation or escape of the concrete, and have a widened shape on the front (3) of the sheath (1) for greater mounting stability. 3. Safety fixing of enclosures between concrete pillars, according to previous claims, it is characterized in that the sheath (1) has a threaded hole (4) to be able to screw a rod (7) and thus be able to leave the assembly ready for use and because the rod (7) has a recess (6) to be able to tighten said rod (7) when it is introduced into the sheath (1). 4. Security fixing of enclosures between concrete pillars, according to previous claims, it is characterized by having a screw with a pallet-shaped head (9) and provided with a thread (8) used to fix the sheath (1) in the formwork plate when introduced into the holes made in it and threaded into the internal thread (4) of said sheath (1), using as many screws as sheaths (1) are required. 5. Fixing security of enclosures between concrete pillars, according to previous claims, it is characterized in that the installation of THE SHEETS (1) in the formwork plates is done only by screwing them through a screw that is unscrewed when The concrete has set.
