Abstract

The method for making a cavity (17) in the thickness of a floor (14) comprises closing the upper part of the cavity with a cover (1) fixed to a formwork panel by means of nails (13b). The formwork consists of a base (4) and a vertical wall (4a). The cover is provided with handles (7) and an embedment (8) connects it to the blub (9) of the vertical walls.

l l La presente invention, destinee au domaine de la construction de batiments, est applicable aux structures beton, notamment: les dalles pleines traditionnelles, les dalles pleines prefabriquees, les dalles type pre-dalles, les dalles alveolaires prefabriquees, et les dalles poutrelles hourdis. Wile concerne plus precisement un procede de coffrage pour realiser les tremies au travers desquelles passeront les toysux d' alimentation et d' evacuation en eau froide ou chaude, les colonnes de ventilation ou de climatisation, et tous reseaux techniques. Apres leur installation, ces divers reseaux d'equipements vent dissimules  l l The present invention, intended for the field of building construction, is applicable to concrete structures, in particular: traditional solid slabs, prefabricated solid slabs, pre-slab type slabs, prefabricated cellular slabs, and slabs of joists. Wile relates more precisely to a formwork process for making the hoppers through which the supply and discharge toys will pass in cold or hot water, the ventilation or air conditioning columns, and all technical networks. After installation, these various hidden equipment networks

Ces tremies, appelees aussi reservations, vent confectionnees sur le site. Cette fabrication presente divers inconvenients: a3 coffrage bois: rudimentaire, difficile a realiser, a decoffrer, et couteux, b) la mise en ceuvre est improvisee, completee parfois avec divers materiaux recuperes sur le site, c3 sa conception ne repond qu'a delimiter grossierement les dimensions des tremies, d) en terme de securite, elle ntapporte aucune reponse, n'assurant pas la continuite du plancher: notamment le plan de travail pour la circulation du personnel, e) la protection contre les chutes de materiaux ou de materiels par les tremies est mal assuree; improvisee sa mise en place necessite un entretien permanent pendant la duree du chantier, f) pendant les intemperies (pluie, neige, etc.), I'eau stinf ltre par les tremies des dalles et empeche les travaux de second aeuvre. Ce qui gene l'avancement du chantier, g) pour effectuer le rebouchage en beton ou au platre des tremies, un coffrage  These hoppers, also called reservations, are made on site. This manufacturing presents various disadvantages: a3 wooden formwork: rudimentary, difficult to carry out, to formwork, and expensive, b) the implementation is improvised, sometimes completed with various materials recovered on the site, c3 its design only responds to delimit roughly the dimensions of the hoppers, d) in terms of security, it does not provide any response, not ensuring the continuity of the floor: in particular the work plan for the circulation of personnel, e) protection against falling materials or materials by the hoppers is poorly insured; improvised its installation requires permanent maintenance for the duration of the site, f) during bad weather (rain, snow, etc.), water seeps through the hoppers of the slabs and prevents the finishing work. What hinders the progress of the site, g) to fill the concrete or plaster hoppers, a formwork

laborieux doit etre realise autour et entre les differents reseaux.  laborious must be carried out around and between the different networks.

Afin d'eliminer tous ces inconvenients designee ci-avant, le but de la presente invention est de proposer trots coffrages de fabrication industrielle, en matibre l plastique ou metal, ou tout autre materisu. Ce coffrage sera concu selon trots possibilites: A) en trots elements: figures 3 et 4- un couvercle 1, un element quatre faces  In order to eliminate all these drawbacks described above, the purpose of the present invention is to provide three formwork forms of industrial manufacture, in plastic or metal material, or any other material. This formwork will be designed according to trots possibilities: A) in trots elements: Figures 3 and 4- a cover 1, a four-sided element

Dans les conceptions A et B. les elements assembles formeront une bo^te trapezo'dale. L'invention atteint son but par le fait que cette bo^te, dont la hauteur est egale a l'epaisseur de la dalle, est fixce sur le panneau coffrant 6 et incorporee au courage du beton 14. La bo^te creera une tremie calibree et assurera, grace a sa conception, la fermeture et ltetancheite de la tremie pendant les travaux de gros  In designs A and B. the elements together will form a trapezoidal box. The invention achieves its object by the fact that this box, the height of which is equal to the thickness of the slab, is fixed on the shuttering panel 6 and incorporated into the courage of the concrete 14. The box will create a hopper calibrated and will ensure, thanks to its design, the closing and the tightness of the hopper during the big works

The assembly forms a trapezoidal box with a cover 1. This principle is intended for users who agree to leave FIG. 5 in con1act the wall 4a incorporated between the filling 18 and the concrete structure 14. FIG. 3 vertical section represents an assembly 17 forming a trapezoidal box composed of a vertical wall 2 around the entire periphery, connected to a base 3, and of a cover 1. The particularity of this second principle ffgure 6 makes it possible to remove the wall- 2 before filling 18- of the t-remie- 17. These two forms, Figures 1- and 3 are made of plastic; made of metal or other material, industrially made, trapezoidal shape and having a cover

The upper wall 26 forming the cover and its vertical pa king has the ante 26a, arranged inside the pa king 2 5 formed at the base, itself fixed on the formwork panel 6 by means of a nail 13b passing through the wall of the imprint 30 by a circular orifice 31. The vertical walls 26a and 25a are held together by means of pins 23 passing through circular orifices
