Self-climbing modular system for the protection of civil works and buildings under construction

Abstract

Self-climbing modular systems for the protection of civil works and buildings under construction. One such system includes two spaced-apart bases fixed in cantilever with respect to a slab level, with each one provided at its free end with a support on which an upright is arranged with the possibility of guided vertical displacement with respect to the base and the slab level on which the base is fixed. One or more handrails articulated at their ends link together two uprights of one and the same module or of contiguous modules located at one and the same slab level. The one or more handrails being configured to telescopically lengthen upon the one upright being vertically displaced without there being a same vertical displacement of the other upright.

1 . A self-climbing modular system for the protection of a structure under construction, the self-climbing modular system comprising:
 a first base fixed in cantilever with a first slab of the structure, an end of the first base including a first support;   a second base spaced-apart from the first base and fixed in cantilever with the first slab, an end of the second base including a second support;   a first upright having a portion thereof arranged in the first support, the first upright and the first support being configured to allow guided vertical displacement of the first upright with respect to the first base;   a second upright having a portion thereof arranged in the second support, the second upright and the second support being configured to allow guided vertical displacement of the second upright with respect to the second base, the first and second uprights being vertically displaceable independent of one another; and   one or more handrails that each has a first articulated end coupled to the first upright and a second articulated end coupled to the second upright, each of the one or more handrails comprising a first portion that includes the first articulated end and a second portion that includes the second articulated end, the first portion being slidable inside the second portion, each of the one or more handrails being configured to telescopically lengthen upon the first upright being vertically displaced without there being a same vertical displacement of the second upright.   
     
     
         2 . The self-climbing modular system according to  claim 1 , wherein the one or more handrails are configured to telescopically lengthen upon the first upright being vertically displaced without there being a vertical displacement of the second upright. 
     
     
         3 . The self-climbing modular system according to  claim 1 , wherein each of the first and second uprights comprises first and second U-shaped posts that are coupled to one another by a plurality of bolts. 
     
     
         4 . The self-climbing modular system according to  claim 3 , wherein each of the first and second U-shaped posts includes a web, the plurality of bolts securing the web of the first U-shaped post to the web of the second U-shaped post. 
     
     
         5 . The self-climbing modular system according to  claim 1 , wherein each of the first base and second base comprises first and second longitudinal members that is each fixed to the slab. 
     
     
         6 . The self-climbing modular system according to  claim 5 , wherein the first and second longitudinal members are each U-shaped and are separated from one another by a gap having a constant width. 
     
     
         7 . The self-climbing modular system according to  claim 5 , wherein each of the first support and second support comprises a first lateral flange secured to the first longitudinal member and a second lateral flange secured to the second longitudinal member, the first lateral flange having fixed thereto one or more rollers that reside in a first guide of the respective first and second uprights, the second lateral flange having fixed thereto one or more rollers that reside in a second guide of the respective first and second uprights. 
     
     
         8 . The self-climbing modular system according to  claim 1 , comprising first and second handrails to which a taut safety net is fixed. 
     
     
         9 . The self-climbing modular system according to  claim 1 , further comprising a first extendable tie rod that braces the first upright to the first base, the first extendable tie rod having a first end secured to the first upright and a second end secured to the first base. 
     
     
         10 . The self-climbing modular system according to  claim 9 , further comprising a second extendable tie rod that braces the second upright to the second base, the second extendable tie rod having a first end secured to the second upright and a second end secured to the second base. 
     
     
         11 . The self-climbing modular system according to  claim 9 , wherein the first extendable tie rod includes a first portion coupled to the first upright and a second portion coupled to the first base, the first portion being slidable inside the second portion. 
     
     
         12 . The self-climbing modular system according to  claim 11 , wherein the first portion of the first extendable tie rod incudes a flat bar having disposed along a length thereof a plurality of spaced-apart through holes, the second portion of the first extendable tie rod including a hollow body having first and second holes respectively located on first and second opposite sides of the hollow body, there being a bolt extending through the first and second holes of the hollow body and one of the plurality of holes in the flat bar to fix a length of the first extendable tie bar.
