ES1195861U - Anchorage embedded in concrete with textile ring (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Embedded anchor in concrete with a textile ring characterized in that it comprises a flat textile tape forming a ring (2) and a hollow container (1) of semi-rigid material open on its upper side. The container (1) has a cover (6) that hermetically closes the upper opening, an externally facing flat fastening flange (3) which is located on the upper peripheral edge, and a straight cut (4) located in the base of the container (1), which is elastically deformable and which has a length equal to or greater than the width of the ring (2). The ring (2) contacts the cut (4) along the entire width of the tape and is joined by pressure exerted by the container (1) in the area of the cut (4), so that a part of the ring (2) is free on the outside of the container (1) and the other part of the ring (2) is housed in the area delimited by the container (1) and the cover (6) forming an anchor point.

DESCRIPTION

Anchor embedded in concrete with textile ring.

Technical sector in which the invention is framed

The present invention relates to an anchor embedded in concrete that can be used for the placement of life lines or as an anchor point of a safety harness.

State of the art

Currently, several patents and utility models of anchors for life lines are known.

In document ES 1 068 470 U an anchor is proposed for hooking safety elements in construction.

This invention has the disadvantage of the difficulty of passing the ends of the rod through two opposite holes in the housing that houses it. It is also difficult to ensure the position of the rod with respect to the box before the setting of the concrete, being necessary to tie the rod to the reinforcement of the concrete.

In document ES 1068470U an anchor is presented for attachment of safety elements in constructions which is a box with adhesive that houses a coupling element.

This invention has the disadvantage that the hooking element cannot be properly fixed inside the box.

In document ES 1 072 008 U an energy absorbing anchor for falls in height is presented which presents the inconvenience of needing mooring holes to the structure.

In US200103243SA1 an invention is presented that presents the drawback of presenting a mounting system with removable elements and need for tools.

Document ES 2 311 310 B1 presents a system that leaves a metallic part of the anchor lost, resulting in high cost.

Due to the above, an economic and simple system for the placement of life lines and anchor point for harness in concrete is still necessary.

Explanation of the invention

The anchor for embedding in concrete object of invention is mainly used to place mooring points for work with harnesses or life lines in concrete structures made by means of wooden formwork.

The anchor is formed by a ring (2) made of sewn flat textile tape and a semi-rigid hollow container (1) that has, in its upper part, a lid (6) and an externally oriented fixing flange (3) , and at its base a cut (4), so that the ring (2) is connected by pressure to the container (1) in the area of the cut (4),

one part of the ring (2) remaining inside the container (1) and the other part (2) outside it.

The anchor is placed in position before pouring concrete, once the formwork and the reinforcement of corrugated steel rods (7) are assembled. To do this, the part of the ring (2) that is outside the container (1) will be joined first with a rod (7) of the steel assembly by means of a hanged knot. Subsequently, the face of the container (1) that has the fixing flange (3) against the formwork wood will be supported and fixed thereto and finally the structure will be concreted.

Once the concrete curing time has elapsed and the structure is stripped, the lid (6) of the container (1) will remain on the concrete surface, which can be opened to release an anchor point formed by a textile ring in which You can place a carabiner or any other element of union of an anti-warp system.

Brief description of the drawings

Figure 1 shows a recent (1) hole that has a fixing flange (3), a cover (6) and a cut (4). The fixing flange (3) has two holes (5) that facilitate nailing or screwing the container (1) to the formwork surface.

Figure 2 shows, in the left part, the sequence of the anchor assembly in which the ring (2) is passed through the cut (4). In the right part the union is represented by a knot hanged from the ring (2) with a rod (7) of the structure assembly.

(Afterwards, the lid (6) must be closed and the nailing or bolting of the flange (3) against the formwork wood and the concrete concreting of the structure).

Detailed exposition of an embodiment

The anchor assembly will preferably be made at the factory and will consist of the introduction of a part of the ring (2) inside the container (1) through the cut (4) of the base, closing the lid (6) last .

To facilitate the assembly process, the container (1) will preferably be of deformable plastic material to fulfill a double objective: on the one hand, the entrance of the ring (2) in its interior will be favored, and on the other hand the union of the container will be favored (1) and the ring (2) by pressure, preventing the ring (2) from moving and leaving the container (1) during manipulation.

To protect the textile ring (2) and prevent the entry of fresh concrete and dirt inside the container (1), the lid (6) will adjust tightly. The lid (6) may be independent of the container (1) or may be attached thereto through a fold line located on the flange (3).

In addition, the entry of fresh concrete into the container (1) through the cutting area (4) should also be avoided. To do this, the textile tape should contact the cut (4) along the entire width of the tape, avoiding folds that cause a greater opening of the cut (4).

In the first place a possibility of embodiment is described in which the anchor is designed to join the formwork wood by nailing or screwing the

pestana (3). In this case, the flange (3) will have holes (5) for positioning the tips or screws.

In this case, care should be taken to check the surface after the removal of the formwork to verify that there are no points or screws that could damage the textile ring (2).

Secondly, a possibility of realization is described in which it is not necessary to use tips or screws for fixing the container (1) to the formwork. In this case, the container (1) can be joined against the formwork by exerting pressure with a pusher that simultaneously contacts the container (1) and with the steel assembly, presenting the advantage that it will not be necessary to check the concrete surface as in the previous case. This pusher could be a metal or plastic bar wired to the steel assembly, for example.

In all cases the edges of the container (1) may have a rounded shape to prevent damage to the textile ring (2).

In all cases, the container (1) or the anchor belt may contain text with 20 references to the manufacturer, regulations, expiration or resistance of the anchor.

Claims (3)

1. Concrete embedded anchor with textile ring characterized in that it comprises a flat textile tape that forms a ring (2) and a hollow container (1) of semi-rigid material 5 open on its upper side. The container (1) has a lid (6) that tightly closes the upper opening, an outwardly oriented flat fixing flange (3) that is located in the upper perimeter edge, and a straight cut (4) located at the base of the container (l), which is elastically deformable and having a length equal to or greater than the width of the ring (2). The ring (2) contacts the cut (4) along the entire width of the 10 tape and is connected by pressure exerted by the container (1) in the area of the cut (4), so that one part of the ring (2) is free outside the container (1) and the other part of the ring (2) is housed in the area delimited by the container (1) and the lid (6) forming an anchor point. 15 2.
