Self-climbing perimetric protection system for construction works in buildings

A self-climbing perimetric protection system for construction works in buildings, said system comprising at least one module comprising:

• at least two masts spaced apart from one another, each mast of the at least two masts being formed by a first vertical channel iron and a second vertical channel iron, wherein the first and the second vertical channel irons respectively have a U-shaped cross section comprising a central section and a pair of side sections, wherein a first mast of the at least two masts is constructed such that said central section of the first vertical channel iron of the first mast faces said central section of the second vertical channel iron of the first mast, and the pair of side sections of the first vertical channel iron of the first mast extends opposite to the pair of side sections of the second vertical channel iron of the first mast, and wherein a second mast of the at least two masts is constructed such that said central section of the first vertical channel iron of the second mast faces said central section of the second vertical channel iron of the second mast, and the pair of side sections of the first vertical channel iron of the second mast extends opposite to the pair of side sections of the second vertical channel iron of the second mast;
• a vertical protection panel attached to the at least two masts;
• a plurality of pairs of support elements arranged in different horizontal planes between the first and the second vertical channel irons of the first and the second masts of the at least two masts for supporting the at least two masts during a phase of a hoisting process for hoisting the at least two masts and during a working phase;
• a plurality of pairs of anchors configured to be immobilized at different heights in a building in which the system is used, so that the plurality of pairs of anchors guide the at least two masts, wherein each anchor of the plurality of pairs of anchors comprises:
• an anchoring frame;
• and
• a guiding head coupled to the anchoring frame, wherein the guiding head comprises:
• a pair of mobile horizontal claws, wherein, in a closed position, a first mobile horizontal claw of the pair of mobile horizontal claws braces one side section of the pair of side sections of the first vertical channel iron, which is adjacent to the guiding head, of a respective one mast of the at least two masts, and a second mobile horizontal claw of the pair of mobile horizontal claws braces one side section of the pair of side sections of the second vertical channel iron, which is adjacent to the guiding head, of the one mast of the at least two masts;
• a bearing rocker comprising a front part adjacent to the one mast of the at least two masts to which the guiding head is braced, an intermediate part traversed by a horizontal rotation shaft, and a rear part, the bearing rocker being configured to rotate in a vertical plane between a working position, in which said front part supports one support element of the plurality of pairs of support elements that is adjacent to the guiding head, and a release position, in which said front part is positioned from the one of the at least two masts to which the guiding head is braced, to allow at least the one support element of the plurality of pairs of support elements that is adjacent to the guiding head to pass during the hoisting process;
• a stop element, wherein, when in the working position, the rear part of the bearing rocker abuts against the stop element;
• and
• a pair of side plates which are attached to one another by an upper horizontal plate and a lower horizontal plate located in respective horizontal recesses of the pair of side plates;
• wherein each mobile horizontal claw of the pair of mobile horizontal claws comprises a first end part, the first and second mobile horizontal claws being articulated with one another at a common vertical rotation shaft, wherein the common vertical rotation shaft traverses a vertical opening in said upper horizontal plate, a vertical opening in said lower horizontal plate, and a vertical opening in said first end part of each of said first and second mobile horizontal claws;
• each mobile horizontal claw of the pair of mobile horizontal claws further comprising a central part having a vertical through-hole, the vertical through-holes of the first and second mobile horizontal claws capable of being aligned and traversed by a vertical locking element which keeps the pair of mobile horizontal claws in the closed position;
• each mobile horizontal claw of the pair of mobile horizontal claws further comprising a free second end part, the free second end parts of the pair of mobile horizontal claws being configured to brace the one side section of each of the pair of vertical channel irons of the one mast of the at least two masts that is adjacent to the guiding head when the pair of mobile horizontal claws is in the closed position, thus forming a guidance passage for a vertical movement of the one of the at least two masts;
• wherein at least one pair of anchors of the plurality of pairs of anchors is arranged in a horizontal plane, and the guiding heads of the at least one pair of anchors hold onto said at least two masts when in said hoisting process and when in the working phase.
