Abstract

System holds networks and lifelines for construction, consisting of two removable parts, one in square that acts as a support and anchoring to the floor and another, a pole attached to the same square by two buffoons that keeps the same in ideal position to hold two networks at different levels and avoid falls in height at the edges of the floor. Said pole in its upper part or head is provided with four rings to hold the nets and pins for slings with tensioners, to keep the cable of life line taut. the brackets fixed to the floor by threaded billets of steel, remain as railings to provide them with tensioned cables before removing the poles and nets, so that at no time be left unprotected the edges of the floors.

Description

System subject networks and lifelines for the building.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a system of subjection of networks and lifelines, which has been designed to avoid falls in height of the operators that execute structures, as well as the protection of those workers who place the formwork systems and are unprotected from falls from the plant where they work at the bottom.

Well, the system consists of poles designed in such a way that they protect from falling on three floors different, in addition to acting as lifeline supports for the fastening of cables that previously subject to tensioners, gets secure mooring lines where operators are held, thus avoiding possible falls both on the facades like from one plant to another.

In addition the brackets in square of the poles, they can stay as guardrail, placing previously tensioned steel cables between supports with this get that before removing the networks, they are protected the edges of the slabs.

Background of the invention

Some poles subject to nets are known for fall protection on the forged edges with more or less efficiency, but not a pole that integrates the three functions, of protection from falls on the edges of the structure, lifeline when placing the planks, and railing conditioning before of removing the networks.

Description of the invention

The system is based on the design of a pole with four studs threaded into the concrete, so that keeping it tilted by a square that goes fastened to the pole by two through bolts get a 45 ° inclination on the horizontal plane of the ground, and by a break in its final section is achieved the ideal placement of two nets, one at the bottom that allows the decoupling and plant protection without any danger of falling and another that allows protect from the fall of the upper level.

Likewise, the pole carries on its head a system that collects the ropes of both networks and the cable of the lifeline that is installed between two opposite poles, the Life line cable is tensioned by slings with tensioners.

To this lifelines will be attached with harness and adequate antacid protection to prevent any type of fall from the work floor.

The pole has some rings for its transfer and placement with the crane so that it is in its position of job.

When the plant system is raised, the pole of the square that has previously been provided with cables linearly to leave it as a railing.

Description of the drawings

Figure 1 corresponds to two poles faced with their corresponding networks subject to the slab and lifeline between both poles for system placement fall arrest

Figure 2 corresponds to an elevation in which they see both networks deployed at both levels.

Figure 3 corresponds to the plan of how it is mounted the system with its lifelines separated every 5 meters approximately.

Figure 4 details a possible fall and the operation of the fall arrest system that would prevent it.

Figure 5 details the anchor to the floor.

Figure 6 details the template tool for leave the pole clamping studs to the exact extent in the fresh concrete.

Figure 7 reflects the detail of the head of the pole for fastening the ropes of the nets and the line of life.

Figure 8 details the railing with cable and set perspective.

Figure 9 details the form and composition of the pole, with anchor mode, net clamping and cable tensioner of the lifeline, as well as anchors for transport and placement of the pole in work.

Figure 10, details how the railing is formed once removed the poles of its base anchorage.

Description of a preferred embodiment

In view of the commented figures, the pole should be built in 700x700 square structural steel tube mm, with through bolts and gangs to the anchor square that It will be of the same material and section. The anchor zone will look reinforced by two 15 mm thick palastro plates and with two holes to facilitate the passage of the anchors.

The dimensions indicated in the drawings for its use in the heights of more common plants, as well as life line cables and standardized networks for effort and use required.

Claims (1)

1. System subject networks and lifelines for the construction, consisting of two removable parts, one in square that acts as support and anchor to the floor, held by two pole bolts that hold the two nets in position ideal to avoid falls in height, and in turn a pole that is fixed to the support described above and in its upper part or head of said pole, the hooks for the nets and passage of slings with tensioners, to keep the line cable tight of life (figure 9). Bracket brackets fixed to the forged by threaded steel billets and by tensioned steel cables, they will remain as a railing in the perimeter of the floor, when dismantling the net carrier pole (Figure 10).
