Description

Tripod life line support for works of building construction

Object of the invention

The present invention relates to a tripod of life line support for building construction works, planned to be mounted with another or others on the area near the edge of the formwork or floor slab of a plant corresponding to a building, so that between consecutive tripods it is arrange a tensioner cable that constitutes a lifeline, on which a ring or sliding carabiner is attached linked to a harness fixing an operator or worker of the work.

The object of the invention is to simplify the means used in security or people working in the building construction, based on the use of simple ones tripods that mount and dismount quickly and easily.

Background of the invention

In the construction of buildings are necessary minimum security measures duly regulated by the Administrations, and among them are the characteristic networks that as bags are suspended profiles in inverted "L" conveniently fixed on the edge of the floor, so that if an operator for any reason falls into a vacuum then is picked up by the network, avoiding its impact on the ground.

Now this security system or means, which is the most used, from the first survey building floor, presents a series of problems and inconveniences, among which the difficulty of set the commented supports in "L" inverted to the structure, especially formwork. In addition, among Profiles and network, the volume is high.

Another problem or inconvenience is that the networks referred to as bags, they constitute receiving means of objects and / or debris that are poured into those networks to avoid being lying on the ground or avoid having to pick them up from the plant in the They originate. That is to say that the commented networks as a stock market they constitute a means of storage of materials (bricks, rubble, wood, iron, etc) that pose a danger of injury serious and even fatal if an operator falls on said safety nets.

Description of the invention

The tripod that is recommended has been conceived to solve the problem described above, since allows to support, with other equals arranged on the perimeter of the corresponding building floor, tension cables or lines of life that serve to hook and slide the element in which a harness linked to the user or person who is working and have a risk of falling into a vacuum.

More specifically, the tripod of the invention, formed by tubular bars that can be fixed at their upper end to a tubular strut and supported by its lower end in the corresponding formwork or forging of the plant in question, it has the peculiarity that the lower end of such strut It is solidary of a plate through which the fixing of the assembly on the formwork or on the floor resulting after concreting.

In the case of fixing on the floor, made through threaded rods through the plate solidarity of the strut, fixing those rods to many others Squares on which precisely supports the plate, supporting by its other end those squares in the formwork and joined by couples using lower crossbars. Said metal frame and formed by the squares, crossbars, plate and rods, will remain immobilized and therefore the tripod strut, when it concretes and set the concrete, thus achieving an easy and effective tripod fixing.

However, when it is intended to fix the tripod directly on the formwork, before pouring concrete, then there is a risk that the operator will face an eventual drop drag with you to the tripod and part of the formwork, of so that to avoid this a fixation is made below the formwork, arranging the strut plate resting on the upper surface of the slab itself, passing the rods threaded plate through formwork, fixing below through a pair of small beams, previously supported by a crossbar common to both, held by a ring or other any element to the formwork itself, then fix by tightening nuts that pair of beams for which they have been Threaded the threaded rods. Those beams will be supported by under the sops or other lower components support the formwork boards, all to avoid the dragging of this one with the tripods, in case of a pull caused by the fall of the operator suspended through the life line harness held or supported between two adjacent tripods.

Based on the type of tripod referred to and the ways of fixing it is solved in a simple, effective way and without problems of assembly and / or disassembly, the security system for those people who work on the plants of the buildings under construction.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation on a perspective of a plant part of a building in construction with two tripods supporting a lifeline for carabiner hook or sliding ring and linked to a harness of a worker and avoid a possible fall from it.

Figure 2.- Shows a perspective view of the frame as a means of fixing the tripod strut to a wrought.

Figure 3.- Shows a perspective view upper formwork on which the support plate is supported of the tripod strut, for fixing it to said formwork

Figure 4.- Shows a perspective view below the means involved in fixing the plate corresponding to the tripod strut on the formwork of the previous figure.

Preferred Embodiment of the Invention

As you can see in the referred figures, and in concrete in figure 1, the tripod of the invention comprises a prop (1) supported by its lower end to a plate metal (2) fixing, so that in proximity to the end top of such strut (1) tubular and inclined bars are fixed (3) of the same characteristics and configuration as mentioned strut (1). The tripod thus formed will be arranged with other peers. on a formwork (4) or forged, depending on whether its fixing is performs directly on the floor prior to the pouring of the concrete formwork, or fixed in the concrete phase for the obtaining the formwork itself.

In any case, between the adjacent tripods that are arranged perimetrically on the floor of the building in the that are applied, a lifeline (5) is held with tensioners, on which a carabiner or similar (6) slider is attached on it, and that constitutes the end of a brace (7) corresponding to a clamping harness for an operator or worker and prevent it from accidentally falling into a vacuum, but that will be suspended from that lifeline (5) through its harness

Fixing the tripod, in the phase of concreting, is done by a frame formed by the own metal plate (2), some squares (8) supporting it, and crossbars (9) that join said lower part of each other squares (8), which are fixed to the plate (2) by threaded rods (10), as shown in Figure 2. The frame thus constituted is arranged on the formwork surface (4), with the prop (1) of the tripod itself, remaining by the pressure exerted by the threaded rod with sufficient rigidity to withstand the operator's thrust.

Regarding the fixing of the strut (1) with the plate (2) and therefore the tripod on the formwork (4), it performed below the formwork tables, by means of respective rods (12) through the plate (2) and the formwork (4), emerging below it to fix it by corresponding nuts (13), after passing the rods (12) through holes of a pair of beams (14) located below the support pads (11) for formwork boards (4), holding those beams (14) previously by means of a crossbar (15) common to both, that with an appropriate ring or element you can hold the formwork itself (4) to allow the threading of the nuts (13) tighten on the rods (12) and fasten the beams (14) under the formwork assembly (4), thereby avoiding that before a pull by fall can be dragged part of the formwork (4) and the tripods attached to it, which could happen if you don't make that special fixation below the formwork.
