ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a carcassing fabric system for the construction of buildings in particular of single-family home dwelling houses.
BACKGROUND OF THE INVENTION
One already knows such carcassing fabric systems comprising:
a base assembly consisting of a plurality of modular tying concrete elements forming the base perimeter of the outside wall of the house, intended to be anchored into the foundations by reinforced concrete piles and connected to each other by horizontal clamping reinforcements,
a bearing structure consisting of metal poles mounted onto the aforesaid tying elements and fastened onto the upper ends of metal crooks which are embedded into the body, generally of trapezoidal shape in cross section, of these elements,
an external concrete boarding forming the external peripheral wall of the house, borne by the aforesaid structure and consisting of a plurality of modular bay panels or framings.
These known systems however generally are very heavy to be handled and need the use of also very heavy lifting means, thereby complicating and extending the duration of mounting of the framework.
One has also proposed to use elements of light concrete but its cost is substantially greater than that of the heavy concrete.
Moreover such building systems are not very much earth-tremor resistant and do not meet the paraseismic standards in force.
OBJECTS AND SUMMARY OF THE INVENTION
The present invention has therefore as its object to remove the aforesaid inconveniences and to propose a paraseismic carcassing fabric system having a limited weight and which is simple and quick to be mounted.
For that purpose the present invention has as its subject a carcassing fabric system for the construction of buildings in particular of single-family home dwelling houses, comprising:
a base assembly consisting of a plurality of modular concrete tying elements forming the base perimeter of the outside wall of the house and intended to be anchored into the foundation by reinforced concrete piles and connected to each other by horizontal clamping reinforcements,
a bearing structure consisting of metal poles which are intended to be mounted onto the aforesaid tying elements and fastened onto the upper ends of metal crooks mounted in these elements,
characterized in that
an inwards open continuous accommodation space extends over the whole length of the tying elements for receiving the horizontal clamping reinforcements which form an uninterrupted chain over the whole periphery of the base,
the aforesaid crooks are suspended at their upper end from a bracket which projects inwards from the tying elements, so that their opposite bent end be located within the aforesaid continuous accommodation space,
the reinforcements of the aforesaid anchoring piles extend substantially vertically from the foundations and are curved while extending through the tying elements to extend substantially horizontally within the aforesaid continuous accommodation space, preferably above the bent ends of the crooks,
all of the crooks, of the horizontal clamping reinforcements and of the reinforcements of the anchoring piles being intended to be embedded into a concrete slab cast on the spot into the aforesaid continuous accommodation space to ensure a closely linked connection therebetween and to permit the continuity and the transmission of the forces exerted upon the house at the foundations, thereby making the system paraseismic.
In view of the presence of the continuous accommodation space over the whole length of the tying elements, the body of the latter exhibits a substantially L-like or C-like shape in cross-section, thereby substantially reducing their weight.
According to another characteristic of the invention, the horizontal clamping reinforcements consist of several horizontal bars, for example four bars arranged into a parallelogram and of several transverse metal frames connecting the bars to each other, preferably arranged at regular spacings and confined inside of the aforesaid continuous accommodation space.
According to still another characteristic of the invention, the crooks, the anchoring piles and the metal poles of the external structure are substantially aligned in a vertical direction.
In an alternative embodiment, the aforesaid bracket may consist of a plurality of projecting portions spaced from each other on the internal upper edge of the tying elements, so that at least two crooks be suspended from each projecting portion.
In this case, one may provide that the reinforcement of an anchoring pile comprises at least two bars which extend vertically from the foundations between the crooks of a same projecting portion and are horizontally curved within the continuous accommodation space in opposite directions, respectively.
One may provide as a modification that the aforesaid bracket consists of a provisional placement jig for retaining the crooks before the casting of the concrete into the aforesaid continuous accommodation space.
The invention is also directed to a carcassing fabric system comprising an external boarding of reinforced concrete forming the external peripheral walls of the house, which is carried by the aforesaid bearing structure and consists of a plurality of modular bay panels or framings.
According to another characteristic of the invention, the aforesaid panels are thin slabs of concrete reinforced on their internal face by a network of crossed ribs which are reinforced with metal bars for example of steel.
According to still another characteristic of the invention, the aforesaid metal poles of the bearing structure are mounted onto the tying elements through the medium of a pole foot plate of which one portion is slightly overhanging outwards for going to be inserted into a positioning notch formed onto the internal face of a starting panel and to possibly also serve as a bearing point for this panel.
One may also provide a notch and an associated bracket over the whole length of one of the upper and lower edges, respectively, of each panel to form a space for receiving a watertight sealing joint between two horizontally adjacent panels or between a starting panel and a subjacent tying element.
According to another characteristic, a notch is formed over the whole height of the side edges of each panel or frame to form an intermediate decompression space between two vertically adjacent panels.
In this case, one may stick, over the whole height of the external flange of an I-metal pole, a self-adhesive strip of impregnated foam intended to be compressed during the clamping of the panels or of the frames onto the poles in order to avoid the cracking of these concrete panels or frames and to ensure the air-tightness at the level of the aforesaid decompression space.
According to still another characteristic of the invention, one may embed into the aforesaid panels or frames, fastening sleeves which are anchored onto their internal reinforcements to withstand the pulling-out force during the fastening of these panels or frames onto the bearing structure.
