    METHOD FOR MANUFACTURING A BUILDING FLOOR ON PONCTUAL FOUNDATIONS AND CONSTRUCTION ASSEMBLY FOR CARRYING OUT SAID METHOD
    Technical area :
    The present invention relates to a method of manufacturing a building floor on punctual foundations, said floor being made by casting on site a concrete compression slab on a supporting structure. The invention also relates to a construction assembly for implementing said method.
    Prior art:
    Traditionally to make so-called punctual foundations, which are also called isolated or sectoral contrary to linear or linear foundations, the plant dull is scoured and the soil is excavated punctually to pour concrete foundation pads while taking care to level them, these foundation pads being generally reinforced by a metal frame. Formwork is used to connect the foundation pads to pour concrete support beams between them, usually reinforced by a metal reinforcement that mechanically binds the beams to the foundation studs. Then, we put the floor structure, for example beams and interjoists, before pouring the compression slab. This long and tedious process has been improved by the use of foundation blocks and prefabricated reinforced concrete beams. The foundation pieces are in the form of studs each carried by a soleplate intended to rest on a clean concrete poured into the bottom of the excavations to achieve the leveling of the foundation pieces. These one-piece prefabricated foundation pieces are heavy (more than 2T) to manipulate and align with each other once laid. They are then individually grounded with cast concrete at their center before installing the prefabricated stringers to connect two consecutive foundation pieces. The iongrins are sealed to the foundation pieces by poured concrete in keying areas delimited by forms placed at the right of the foundation pieces, these forms may constitute an angle or a straight line. Once these operations are completed, the floor structure can be laid in order to cast the compression slab. This process is not yet satisfactory given the large number of interventions required to seal or individually key foundation pieces and the rods before you can lay the floor.
    Presentation of the invention
    The present invention aims to overcome these disadvantages by providing a simpler and faster manufacturing process, thus less time consuming on the site, while facilitating the work of the workers and improving the thermal insulation of the floor.
    For this purpose, the invention relates to a method of the kind indicated in the preamble in which we place foundation parts in punctual excavations made in the ground, we put the rods between the foundation pieces, we put external formwork elements and In the interlocking zones between the beams at the foundation pieces, the load-bearing structure of the floor is placed on the foundation pieces, the beams and the interior formwork elements, and the concrete is cast onto the supporting structure to form the floor. floor compression slab and simultaneously seal the foundation pieces on the ground as well as the rods between them and the foundation pieces, during this single concrete pouring operation, which saves considerable time and reduces intervention on the yard.
    For the foundation pieces, prefabricated building elements are preferably used in two parts, comprising a soleplate intended to rest at the bottom of the excavation, and a hollow stud covering the soleplate by means of a peripheral clearance.
    To facilitate the installation of the foundation pieces, it is possible to use a laying template comprising alignment marks and temporary fixing means on the ground.
    At least for the internal formwork elements which will be lost after casting of the compression slab, it is possible to use prefabricated formwork elements made of thermally insulating material arranged to be assembled to the foundation pieces.
    Preferably, fastening brackets are arranged to be assembled to the foundation pieces to hold the outer formwork members against the stringers in the keying areas.
    Before the installation of the stringers, additional form boards may be placed on all or part of the height of the foundation pieces depending on the height of the crawlspace to be made, said boards being held in lateral grooves provided on the foundation pieces. .
    This method can be implemented by means of a specific construction assembly comprising at least two-part prefabricated foundation pieces, comprising a sole and a hollow stud covering the soleplate by means of a peripheral clearance. The sole has for example a substantially square shape and the stud a substantially cubic shape. The stud may comprise at least in its upper face receiving holes and in its sides side grooves.
    This building assembly advantageously comprises reversible fixing brackets, comprising a flat flank arranged to maintain aligned formwork elements and a right-angled sidewall arranged to hold shuttering elements at an angle. To do this, they comprise at least one parallel and opposite to the wall mounting rod arranged to fit into one of the receiving holes provided in the foundation pieces.
    Said building assembly may comprise prefabricated lost formwork elements made of thermally insulating material, arranged to be assembled to the foundation pieces by fixing rods in the receiving holes provided in the foundation pieces.
    Among said set of construction, there can be found a template for laying foundation pieces, including alignment marks and temporary ground fastening means. This laying template may comprise at least one profile defining a right angle corresponding to two adjacent sides of the sole of the foundation piece, and being provided with at least one handling handle and holes for fasteners.

    With reference to the figures, the construction elements allowing the implementation of the method of manufacturing a floor for a building on point foundations according to the invention comprise at least: prefabricated foundation pieces 10 (FIGS. rods 20 (Fig. 5A-C), reversible mounting brackets 30 (Fig. 4), shuttering elements 40 (Figs 5 and 6), and laying templates 50 (Fig. 3). ).
    The prefabricated foundation pieces 10 made of concrete or the like are made of two superimposable parts, namely a sole 11 which forms the interface between the ground and the building, and a stud 12 which covers the sole 11 and allows the installation of the longitudinal members 20. The soleplate 11 is preferably a solid molded piece, incorporating or not an insulating material, provided at its center with a projecting armature 13 made of steel. It has a substantially square shape, the side walls form a draft angle and have alignment marks 18 'in the form of notches. The underside of the sole 11 is flat so that it can be placed on a clean concrete 1. This clean concrete 1 is poured into the bottom of the punctual excavations made in the ground in order to level the foundation pieces 10. The sole 11 has on its flat upper face a central boss 14 defining a peripheral clearance J with the pad 12. The pad 12 meanwhile is preferably a hollow molded part to receive a concrete keying or sealing as explained below. It has a substantially cubic shape, the side walls form a draft angle and the lower face esfplane to be placed on the upper face of the sole 11. Its lower opening 15 is slightly greater than the diameter of the boss 14 to allow its relative displacement in all directions relative to the sole-11- within the limits of the peripheral clearance J. It receives in its center a steel frame 16 to create with the armature 13 protruding from the sole 11 a vertical chaining of recovery of loads. It further comprises on its upper face receiving holes 17, for example four in number, distributed in the corners, side grooves 18 disposed in the center of its side walls, and positioning pins 19 on its upper face. The function of these characteristics will be explained later. The sole 11 'and the pad 12 are each provided with one or more lifting hooks (not shown) or the like, allowing their handling by a hoist such as a truck crane, each piece weighing about Vz ton.
    The stringers 20 are moldings made of concrete or the like with or without steel reinforcement and having an L-shaped section defining a flat outer wall 21 serving as a formwork and an inner rim 22 serving as support for the ends of the beams (not shown) which will be laid over the foundations to create the floor structure in combination with interjoists.
    The fixing brackets 30, an example of which is shown in FIG. 4, are parts made of welded steel or the like, in the form of a U, the parallel branches of which define a flat flank 31 and a right-angled flank 32, arranged to maintain formwork elements 40 respectively aligned and angled. They comprise at the base of the U at least one fastening rod 33 parallel and opposite to the flanks 31 and 32. This fastening rod 33 is provided to fit into one of the receiving holes 17 formed in the stud 12 of the foundation pieces 10. The fastening brackets 30 are stiffened by a reinforcing baue 34 or the like extending between the flanks 31 and 32. Thus, these fastening brackets 30 are reversible as explained below. .
    The formwork elements 40 comprise both recoverable formwork elements 41, since arranged on the outside, and lost formwork elements 42, 43, since arranged inside the foundations. The recoverable formwork elements 41 consist for example of planks or the like, while the lost formwork elements 42, 43 consist of blocks of material, preferably thermally insulating, such as expanded polystyrene or the like with a high density, for serving thermal break and support to the supporting structure of the floor. In the corners of the foundation according to FIGS. 5A to 5C, outside the foundation are used two planks 41 held in abutment against the outer wall 21 of the longitudinal members 20 by three fastening brackets 30 fitted into the receiving holes 17. of the foundation piece 10, two brackets with their flat flank 31 and the angle bracket with its flank at right angles 32. Always in the corners of the foundation, is used inside the foundation to finish the formwork , a cubic block 42 of polystyrene held on the foundation piece 10 by a fastening rod 44 passing through the block and nested in the receiving hole. 17 remaining. In the lengths of the foundation, in accordance with FIGS. 6A and 6B, a board 41 is used outside the foundation, bearing against the outer wall 21 of the longitudinal members 20 by two fastening brackets 30 fitted into the receiving 17 of the foundation piece 10, and having their flat flank 31. Also in the lengths of the foundation, is used inside the foundation to complete the formwork, a parallelepiped block 43 of polystyrene held on the foundation piece 10 by two fixing rods 44 passing through the block and nested in the receiving holes 17 remained free.
    The installation template 50 is not essential, but very useful to facilitate the work of workers especially in land where marking on the ground is difficult. In the example shown in Figure 3, the fitting template 50 comprises two profiles "51 having an L-shaped section and each defining a right angle, it being specified that a half-template or a single profile is sufficient as explained below. They comprise at their respective ends rapid assembly means, for example by interlocking a pin 52 in an orifice 53, or by any other equivalent system, to form a square of dimensions complementary to those of the sole 11. Each profile 51 comprises one or preferably two handles 54 and a plurality of anchoring holes 55, circular and / or oblong, to be able to accommodate • fasteners such as anchor rods or the like, to anchor temporarily, the template on the ground.Also includes alignment marks 56 in the form of notches or the like, facilitating the positioning of the template relative to two axes perpe X-Y ndiculars previously plotted or marked on the site by the workers.
    Possibilities of industrial application:
    The method of manufacturing a floor on point foundations according to the invention is detailed below. It allows the realization of a floor on a crawl space or a technical vacuum, by the casting on the site of a concrete compression slab on a supporting structure. In the intended application, the supporting structure consists of parallel beams connected by interjoists (not shown), but could be different and for example consisting of a prefabricated prefabricated or similar.
    In accordance with the known methods, the topsoil is scoured to a certain depth, occasional excavations are made in the soil at regular intervals to cover the surface of the future building by an XY grid, and a concrete is poured into the bottom of the excavations. cleanliness to upgrade foundations. The X-Y axes are marked on the ground. A foundation piece 10 is placed in each point excavation. Beforehand, it is possible to install a half-jig 50 (FIG 5A-C) or a complete jig, which is easy to align on the XY axes since it is light and hand-manipulable, and is anchored to the ground by anchor rods through the anchoring holes 55. The foundation pieces 10 are placed by a lifting machine which grasps the assembly "sole 11 and stud 12" and deposits each piece of foundation 10 against a template 5Ó previously aligned, which greatly simplifies the alignment of the foundation pieces 10. This alignment can be adjusted by moving by the lifting device only the stud 12 relative to the sole 11 posed through the peripheral clearance J-arranged between the boss. central 14 of the sole and the lower opening 15 of the stud. Stretches 20 ♦ are placed between the foundation pieces 10. This work is also facilitated by the positioning marks 19 provided on the upper face of the studs 12 which correspond to the drawing of the ends of the stringers 20. The formwork elements are then placed. external 41 and 42, 43 interior to close the existing space between the sills 20 to the right of the foundation parts 10 as well in the angles as in the lengths, these spaces being called keying zones. For external forms, planks 41 are pressed against the outer wall 21 of the longitudinal members 20 by using the fixing brackets 30 which are fixed on the foundation pieces 10 by virtue of their fastening rod 33 fitted into the receiving holes 17 of the studs 12. In the lengths, the flat flank 31 is used and, in the corners, the right-angled flank 32 of the same brackets is used. For the interior forms, the cubic blocks 42 are fixed in the parallelepipedal angles and blocks 43 in the lengths on the foundation pieces 10 by the fixing rods 44 fitted into the receiving holes 17 of the studs 12. When the formwork is completed the floor structure is laid on the entire foundation comprising the foundation pieces 10, the longitudinal members 20 and the inner formwork elements 42, 43, the steel trellises are laid to reinforce the floor and the concrete is poured on. the floor structure to form the compression slab. During this single pouring operation, the concrete flows simultaneously into the formwork of the foundations, resulting in the key or sealing of the foundation pieces 10 au'sol and the stringers 20 between them and the foundation pieces 10.
    Thus, it is clear from this description that the invention achieves the goals set, namely a simplification of the structural work to prepare the punctual foundations and a considerable reduction of the intervention time on the site by concentrating in one and same operation, the pouring of the concrete slab compression of the floor and the pouring of the concrete keying foundations, resulting in a speed of execution not equaled to this day.
    Moreover, this method makes it possible to adjust the height of the crawl space or the technical vacuum by inserting additional formwork boards 45, or the like, into the lateral grooves 18 of the foundation pieces 10 as represented in FIG. 6A.
    The present invention is not limited to the embodiment described but extends to any modification and variation obvious to a person skilled in the art while remaining within the scope of protection defined in the appended claims.
