Abstract

Fall safety system with rail anchor for concrete structures.

The fall protection system with rail anchor for concrete structures is formed by a transmitter anchoring device (A) and a receiving device of Tensioning anchor (B).

It comprises two accommodation boxes (1, 1a) with cover (10) and gutter (8). These boxes contain the different pieces that make up the initial and tension anchor respectively; between these pieces is the piece of anchor (2, 2a) whose function is to withstand the tension of all the  system. From one box to another, the cable (4) runs through the channel (8), through the cable guide pieces (7) forming a closed system

The system provides an anchor rail flush with the ground, which allows the operator to be tied with the carabiner of his belt safety harness to prevent falls at any level of work.

Description

Fall safety system with rail anchor for concrete structures.

Technical sector

The invention falls within the sector of construction, specifically in occupational safety as a system of collective protection

State of the art

The basic objective of the Law of Prevention of Labor Risks is that the worker has the highest degree of protection against risks. In the construction of the structure of a building collective protection is basic to the time to avoid accidents and this protection must prevail against Individual protections Within these protections Collective, currently cited: networks, railings, cable life in roof ridge and fixed anchor points (eyebolts).

In practice there is a risk for the operator having to use inadvisable elements such as props, omegas and pillars, when performing tasks in which It needs support. For example in tasks that are performed on the edge of Forged, currently pillar to pillar ropes are placed whose use as a coupling method carries a risk of falling due to possible bad condition of the rope that is not checked or by possible friction cuts with corners of the pillar. Also the use of omegas and omeguillas to tie can lead to the operator being hanging between plant and plant since these are colored just at edge of the perimeter for fastening nets and forks The use of strut as another anchor point is also not advisable since the Strut has its own function.

Today the construction operator is faces a risk of falling when performing certain tasks in which either uses unadvisable anchor points, or faces a greater risk by not having where to look.

Explanation

The present invention relates to a system of fall protection with anchor rail for structures concrete. Its objective is the elimination of broths at any level of work, and its correct use would not even lead to The operator was hanging. It can be used by any construction guild and specifically is aimed at provide anchor coverage in: elevator shafts, interior courtyards, stairwells, floor perimeters, deck and deck cases.

In a construction site it is a fact that as the work grows the risks and the workload increases, especially in the guild overlap.

Exposing a real situation at work, when performs the elevation of networks in upper floors, the plants lower are unprotected having to protect the perimeter with fences. These fences are sometimes removed to be able to perform certain tasks by other guilds thus being hollow or unprotected perimeters, which expose the operator to a risk of drop. The operator, against this risk, uses elements unadvisable anchoring such as pillars, omegas or struts. The invention brings in these situations the necessary and reliable point where the operator can be tied thus preventing the risk of drop.

The invention is simple and effective having the advantage that due to its installation method it does not impede the operator in their tasks, since it runs embedded in the concrete to flush with the surface and all the perimeter at a certain distance from the front. It incorporates two registration boxes (A, B) with cover and plastic material, where the stops of respectively are housed initial anchoring and tensioning. From one box to another runs a steel cable (4), by a plastic gutter (8), which it passes through the cable guide fasteners (7); these pieces have a profiled hole to avoid friction and cable breaks. To this cable is attached the carabiner of the belt of the ames of operator safety offering freedom of movement and perimeter edge security.

The fall protection system with rail anchor is installed at the time of concreting the plants It can be used from start to finish.

Description drawings

Figure 1 shows the security system fall arrest with block anchor rail with all elements by which it is characterized. The system consists of a initial anchoring device (A) and a final tensioning device (B), thus forming a closed circuit.

These devices are housing boxes (1, 1a) with rectangular shape and plastic material whose measurements are 0.50 x 0.05 x 0.05 meters. One end of these boxes it ends in the form of a fan of width 0.20 meters and this is where the initial and final anchor (2, 2a) are inserted respectively. This anchor is a piece of iron that bears on top a through hole that allows the fireman's carabiner to be anchored (3) and at the bottom it shows two pins that are inserted next to The boxes in the concrete. The function of these anchors (2, 2a) is to withstand the tension of the entire system. The carabiner of Firefighter (3) provides the cable hitch (4) to the anchor initial. The cable (4) is 8 \ diameter flexible and high steel resistance that has a double at its ends and is held by cable tie (5) going through a ring (6). This cable runs to through some cable guide pieces (7) along a gutter (8) of plastic material that joins both boxes of accommodation. The tensioning box (B) varies in that it contains the tensioner (9). Both housing boxes incorporate their respective covers (10).

Figure 2 shows a partial view of a security system installed in plant. The cable is observed (4) as it runs through the gutter (8) through a piece cable guide (7). The operator uses the carabiner of its harness to attach to the cable (4).

Figure 3 shows the initial device of anchor (A) in a longitudinal section. Look how they are housed in the concrete the housing box (1) and the piece of anchor (2) and how the different elements are arranged inside of it: the anchoring piece (2), the carabiner (3), the cable (4), the cable tie (5) and the ring (6). Outside the housing box continue the cable guide piece (7) and the gutter (8).

Figure 4 shows the final device of tensioned (B) in a longitudinal section. It is observed how it is housed in concrete the housing (1a) and how they are arranged the different elements within it: the anchor piece (2), the tensioner (9) the cable (4), the cable tie (5) and the ring (6). Outside the housing box the piece continues cable guide (7) and the gutter (8).

Figure 5 shows the profile that characterizes the gutter; profile base curved and open at the top with paths fallen to the sides and at the base two grip pins to concrete

Figure 6 shows in cross section the cable guide part (7), cable (4) and gutter (8). It can be seen that between the bottom of the gutter and the cable there is enough space to hook the carabiner on the belt harness safety.

Embodiment

The fall protection system with rail anchoring is a system designed and designed to prevent falls to Any level of work. Its installation is carried out during the plant concreting since the entire system is housed in the concrete, at ground level, and at some distance from the front avoiding thus hinder the operator in any of his tasks. Is important to note that the fact of being housed in concrete It determines the shape and design of the main pieces.

The invention consists of two housing boxes (1, 1a) with cover designed to protect and house respective initial anchoring and tensioning elements of the cable. Within these elements highlight the anchor piece (2, 2a) characterized by having a through hole that allows anchoring the fireman's carabiner, and two lower hook pins concrete. The importance of this anchor piece resides in its function that is to withstand the tension of the entire system.

Another characteristic piece of this system is the gutter (8) whose function is to serve as accommodation lane for the cable (4) and that joins both anchor and tension boxes. This designed to protect the cable from possible friction with the concrete and allows enough space to hook the carabiner belt safety harness operator.

Finally, highlight the form and function of the guide-cable parts that as indicated by their name guide to the cable in its perimeter route. They are characterized by having a profiled hole where the cable runs and have two concrete hooks.
