Definitions
- the present invention relates to the technical sector of traps which are wooden hatches or accesses that are installed in particular in false ceilings of private residences or factories, workshops, offices or stores and malls, to allow access to the attic or false ceiling.
- Access to the attic or false ceilings can be made necessary for unforeseen maintenance, for example a leak on a pipeline passing through the false ceiling, or repairing wiring, maintenance or repair of an air conditioning system, fire safety systems like sprayers automatic sprinklers, and similar operations, or for any another reason.
- the invention also relates to the installation of the trap according to the invention to the construction, that the pose during an intervention unexpected, in all the places mentioned above, and all the places like.
- a trapdoor comprising a frame formed by four sections is disclosed in WO 9508688A.
- the invention relates to a new trap, characterized by its design in three massive parts, this design making it both industrializable on high precision digital machines, in series and therefore at a very low cost, and aesthetically very attractive.
- the cost is further lowered by the design itself which allows to recover almost all of the cutting part of the counter-base to use it as an access hatch in a lower dimension.
- FIG. 1 it is seen, what is known, that the concrete slab 1 of the ceiling supports steel rods 2 themselves intended for support the weight of the plates 5 (for example “plasterboard” (TM)) of the false ceiling, by means of fishplates 3 and known means attachment 4.
- a water inlet 6 supplies a sprinkler 8 via a valve 7.
- b 40 cm
- a 60 cm
- the prior art therefore consists in cutting out the area a, repairing what must be, then rebuild the false ceiling using a trap door handcrafted, often made on site. This process leads to disadvantages mentioned above.
- FIG. 3 represents the three parts of the trap of FIG. 2, after being placed in position according to the diagram in FIG. 2.
- the base 10 comes in slight overlap of the opening, by its rim 11 which serves as a support and also hides the cutout of the plate 5.
- the base and the counter base are united by the cooperation of a clamping means, for example ( Figure 3) pin positioning or 50 'threaded part and fixing by a screw 60.
- a clamping means for example ( Figure 3) pin positioning or 50 'threaded part and fixing by a screw 60.
- the hatch 20 is wedged in position on the base 10 also by a lateral face shoulder 25. Naturally, the hatch forms a surface 22 full.
- a space 14 is preferably provided on the upper surface of the base 10, between the inner vertical edge 35 of the counter base 30 and the recess 17 of the base 10.
- the trap according to the invention can be produced by any material compatible with its use, and is not limited to wood.
- the trappon could be classified M1 fire resistance for, in particular, shopping centers, or a water repellent treaty for wet rooms such as the water features of villas or apartments, and like.
- Parts 10, 20 and 30 can be machined on machines digital cutting, according to the preferred example, in solid wood. Each of them is therefore in one piece, therefore not causing cracks on the trappon itself, which is a big advantage, as explained above. In addition, the saving of time is quite important compared to an artisanal trappon, as well as the reduction Cost.
- the dimensions standardized, or at least usual, for the passage or manhole 15 are 30x30, or 40x40, or 50x50, or 60x60, or 80x40.
- One of the advantages of the invention is that, when one goes make a series of cuts in a counter base piece 30 to cut the opening 32, it will be possible to recover the cut piece so that it becomes a hatch.
- the invention also relates to a method for accessing a false ceiling of shopping center, workshop, factory, or villa or individual apartment (including access to the attic), or similar, according to which one cuts during construction or after construction a part of the false ceiling providing access to it, characterized by what it includes the installation of a trap as defined above.
Description
- la figure 1 représente le schéma de montage classique d'un faux-plafond ;
- la figure 2 représente le trappon selon l'invention, en vue en perspective éclatée qui permet de représenter les trois pièces et leur mode de coopération ;
- la figure 3 représente la coupe du trappon selon l'invention, en position sur l'ouverture ménagée dans le faux plafond.
- une base 10 , comportant une ouverture centrale 15 formant trou d'homme, cette base étant adaptée pour venir en recouvrement de l'ouverture ménagée dans le faux-plafond, sous celui-ci, et étant apte à recevoir la trappe 20, et apte à coopérer avec la contre-base 30 ;
- une trappe 20 adaptée pour fermer l'ouverture 15 et pour reposer sur un épaulement de la base 10 établi sur au moins une partie du pourtour inférieur du trou d'homme 15;
- une contre-base 30 adaptée pour venir en recouvrement de l'ouverture ménagée dans le faux plafond, par le dessus, et comportant une ouverture centrale 35 de dimensions très légèrement supérieures à celles de l'ouverture 15, de manière à autoriser le passage de la trappe 15,
