Description

Flexible anchor for tying a zuncho elastic to a wall of wall.

Object of the invention

The present invention belongs to the field of construction, specifically that of building rehabilitation historical.

The object of the invention is focused on providing the means for attaching a stretch of elastic material to a wall of wall, so that the deformations of the zuncho do not transmit efforts to the wall.

Background of the invention

In the restorations of historical buildings affected by pathologies caused by cover thrusts on the walls or other factors of a diverse nature, these are usually tied walls in its coronation by means of concrete or metallic material However, within a few years of doing this zunchado, new and more serious pathologies appear, because This type of slip introduces excessive head stiffness of the walls composed of stone factories or masonry. This rigidity is very harmful in case of movements of the Own building or seismic.

This fact is aggravated when the constructions they are of wall, that is, of walls built with mortar of earth, organic components and lime, compacted and rammed between two wooden formwork, called tapial. This type of constructions are especially fragile, not only because of their expansion coefficient, but also for its own composition and way of building These are walls that do not resist efforts to bending, and even less to traction, so it is obvious that you have to avoid placing elements with new materials, rigid and not organic, which can produce a large mechanical arm in the factory of tapia, in addition to an undesirable transmission of salts from concrete or iron oxides to the old factory, causing a deterioration much faster than the one that has been suffering in the Over the years.

Walls of tapia are usually a technique usual construction in historic buildings, usually vintage Muslim, such as walls, towers, alcazabas castles, etc. When you have to restore, consolidate or repair them, it is very important the conservation of its exterior image, according to the norms international restaurants, so you have to avoid possible added or exposed elements that may distort or modify said exterior image.

A little aggressive zunchado for this type of wall walls can be made with wooden elements laminate, a material that is organic and biodegradable with the time, but at the same time it has a great structural resistance and great flexibility The laminated wood trunks, so that work in solidarity with the tapia factory, they must go anchored to it. The problem arises with the different coefficients of expansion of the materials: the stone, the mampuestos and the wall have a great thermal inertia; for him On the contrary, wood is much more sensitive to conditions environmental. These different expansion coefficients can cause serious problems, since an anchor too rigid of the zuncho can cause unwanted thrusts in the walls, being able to get to collapse them.

The technical problem that arises is that of find a means of anchoring the wall of laminated wood to the wall of wall that prevents the expansion of the wood that makes up the Zuncho can cause its expansion and, instead of tying, finish pushing the walls, causing the opposite effect to the one want.

Description of the invention

With the present invention the problem described above, by using an anchor flexible that links a zuncho to a wall and that prevents, when the wooden board is dilated by the effect of temperature, humidity, etc., said zuncho push the wall.

The flexible anchor for strapping wall elastic walls of the invention comprise as an element Main a cable. The installation and operation of the anchor, as well as the rest of its component parts, are explained to continuation:

Blind drills are tilted in a wall on which it is intended to place an elastic strap, such that, but without limit to laminated wood. In each of the drills a threaded rod is introduced, preferably steel stainless, attached to a cable, endowed with flanges and fasteners at its ends. Blind inclined drills are fill, prior to the introduction of corrugated bars, of a suitable fluid material that, after solidification causes the grip From the bars to the wall. This material can be a grout of mortar, preferably lime mortar.

Between the zuncho and the wall an iron is arranged of flexible material, which can be expanded polystyrene, and it leads the cable through a hole in the griddle. On angular or mounting bushes the zuncho, which will have also been drilled by the that the cable and threaded rod will be passed. Free end of the cable is attached, by flanges and fasteners, to a stud that protrudes with respect to the drill of the zuncho, so that said cable is completely inside the zuncho, initially without tense. The union is materialized by a threaded nut to the stud that presses a rubber gasket located between the nut and the zuncho An additional washer can be provided between the nut and the rubber wedge, in order to ensure the Union.

The nut determines tensile stresses on the stud, which cause the cable to tension bracing that way to the wall. The zuncho thus fixed to the wall with threaded rods absorbs loads and possible movements horizontal of the factory walls.

The harmful thrusts of dilation expansive of the zuncho towards the wall, due to the effects combined with humidity and temperature, they are absorbed by the space between the wall and the wall, and in this case the cable is distends and prevents the zuncho from pushing the inserted rods on the wall, which hold it and thus avoiding such efforts fall on the wall.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a sectional view. cross section of the wall, in which the components of the flexible anchor for anchoring elastic straps to walls of wall.

Preferred Embodiment of the Invention

Figure 1 shows the components and the arrangement of the elastic anchor of the invention. The wall (1) to that you want to attach the laminate (8) of laminated wood presents some blind inclined drills (2) that are filled with lime mortar (14) and in which a threaded steel bar is inserted stainless (3). Said threaded rod (3) is joined by means of flanges and fasteners (4) to a cable (6).

Said cable (6) is housed in a hole (7) made in the zuncho (8) and joins at its other end, by flanges and fasteners (4), to a stud (5). Said stud (5) protrudes from the zuncho (8) and is attached to it by means of a nut (11), threaded into the stud (5), and a gasket (10), located between the strap (8) and the nut (11). Additionally you can arrange a washer (not shown) located between the nut (11) and the board (10).

The drill (7) made in the strap (8) is communicates with the blind inclined drill (2) through an iron (9) of expanded polystyrene that is located between the strip (8) and the wall (1). By means of angles or bushings (12) and thyme (13) the attachment of the zuncho (8) to the wall can be attached and secured (1) during its construction.

As seen in figure 1, the cable (6) is It is initially relaxed. As a consequence of the movement of the walls (1), a displacement occurs, in the direction of the arrows, of the stud assembly (5) - nut (11) - seal (10) which, By being attached to the cable (6), you will pull it. Can arrive a moment in which the movements of the wall (1) acquire such dimension the cable (6) becomes tensioned. But, until then, the zuncho dilations (8) will manifest in an elongation (without tension) of the cable (6), and not at an added load on the wall (one).
