Description

-1-

  The invention relates to the construction of buildings

  particularly those for which excellent

  thermal insulation is sought.

  With common construction processes, floors are in close thermal contact with exterior walls When excellent insulation is achieved

  moreover, at the openings in particular

  ment, the fact remains that the thermal conduction var the floor and the walls allows the transfer of a significant amount of heat And attempts to solve this problem come up against real difficulties: they lead to construction methods poorly accepted by manufacturers and / or users, or else

  not technically-satisfying.

  The present invention, on the contrary, brings an elegant solution to this problem, which moreover offers the advantage of being easily inserted into the usual construction methods, and even eliminating some of their disadvantages of implementation.

artwork.

  An essential element of this solution consists of a device for supporting the floor on a wall, which generally comprises: an open box defined by at least one side wall resting on the arched outline of a bottom lower flat, while the free edge of the bottom and the lateral free edges of the wall are substantially coplanar, the side wall of this box comprising a continuous insulating material, the lower bottom of the box comprising a layer

  deformable, and being susceptible to piercing sensi-

  in its center, the box being intended to be embedded in a wall, its coplanar edges flush with the surface of it, while irons of a frame of the floor form an elbow around a stud vertical engaged, through the hole in the bottom of the

  box, in a cell in the wall, the assembly being solid

  used in pouring concrete from the floor, which allows a mechanical connection with excellent insulation

between floor and wall.

  In the vast majority of cases, the box is completed with an upper bottom which also includes an insulating material, and is also capable of

  drilling, for vertical positioning of the stud.

  In an embodiment currently

  flabbergasted as preferential, the box is in the shape of a trunk of half-prism with regular octagonal base However, one can also use a box in the shape of trunk of

half cylinder with circular base.

  On the other hand, in terms of its structure, the box can have its shape defined by a rigid thin envelope, preferably made of synthetic material, while

  at least as far as its side wall is concerned.

  Alternatively, the aforementioned continuous insulating material is itself rigid and directly defines the

shape of the box.

  According to another aspect of the invention, the side wall of the box has lateral extensions towards the outside, substantially coplanar at the edges

free from the box.

  Very advantageously, the bottom bottom of the box has a pocket towards the outside, capable of defining for the stud an oblong cell according to the large

horizontal dimension of the wall.

  Preferably, the continuous insulating material is a cellular synthetic material, such as foam.

  polyurethane, polyvinyl chloride or polys-

  tyrene From its side, the bottom of the box is in

  synthetic rubber of the neoprene type.

  2 $ 6 f? 73 -3- From the support device defined above, the invention also provides a construction method, of the type in which concrete is poured onto

  reinforcement, exterior walls, then at least one floor.

  The proposed method is remarkable for the following operations: a) inserting from place to place in the walls support devices as defined according to the invention, b) providing the walls with an insulating layer at the floor locations,

  c) provide engaged elbows in the floor reinforcement -

  inside each of the support devices, d) pass a stud through each support device

  vertical engaged in a cell in the wall under the provision

  support, and passing through the elbow (s)

  of the frame, after which the pouring of the-

  floor concrete secures the stud to the floor, the part of which enters the hollow of the device

  support ensures the mechanical connection with the wall.

  According to another aspect of the invention, the opera-

  a) includes: fixing the boot to the formwork of the wall, using a suitable stud inside the boot and retained in it by the stud, and pouring the concrete, while the operation b) of placing the insulating layer can be done between the boxes thus fixed by the studs, the stud being then removed to extract the studs

before the operation c).

  Other features and benefits of

  the invention will appear on reading the description

  detailed which follows, made with reference to the accompanying drawings, in which: FIGS. 1A to 1C illustrate a fixing box according to the present invention, as well as its implementation within the framework of the proposed construction process;

  Figures 2 and 3 are respectively horizontal sections.

  horizontal and vertical of the support box; Figure 4 is also a vertical section of the support box, but after installation of the floor, reinforcement and concreting; and Figure 5 is a top view of the same box in its wall, better showing the placement of

floor reinforcement.

  Before describing the present invention in detail, it seems useful to recall the construction process

  commonly used today.

  Traditionally, in situ cast floor supports are made continuously on the

load-bearing walls.

  This system has several drawbacks the linear heat losses are significant

  they are of the order of 0.6 to 0.7 watts per cubic meter

  nary and by degree centigrade, that is to say that if the wall is highly insulated, 1 linear meter of junction corresponds to 1 to 2 m 2 of wall in terms of

heat loss.

  these junctions very often constitute heteroge-

  thermal births, causing condensation, as well

  only alterations of the coating and its finishes.

  the use, in exterior, of walls with strong insulation can lead to important differential thermal expansions between the exterior wall and the interior floor, from where risks of significant cracks,

which are found in practice.

  A known and often used solution

  consists in carrying out thermal insulation from the outside.

  If it has certain advantages, this solution pos-

  There are also contraindications, which limit their use. These contraindications are both technical and aesthetic in nature: users

often accept it badly.

  The solution proposed according to the present invention can be considered as involving point supports between the floor and the wall, these point supports

  having an insulating cut.

  In FIG. 1A, the reference numeral 1 designates a box, generally consisting of a side wall 2, a bottom bottom 3 and an upper bottom 4 We can immediately see that this box is open The bottom bottom 3, of same as the upper bottom 4, which is moreover not always imperative, define a

  arched outline on which the side wall 2 rests.

  In FIG. 2, it can be seen that the free edge 38 of the bottom 3 and the lateral free edges 26 and 27 of the

  side wall 2 are substantially coplanar.

  In the preferred embodiment shown, the box is in the form of a half-prism trunk with regular octagonal base. It can immediately be seen that the sides 21, 22 and 24 belong to an octagon, of which 23 and 25 are half-sides. this form is currently considered preferable, in particular to allow the reinforcement proper to the wall M of FIG. 1A, it is possible to use other prismatic or cylindrical forms with regular bases, and in particular

  half-cylinder shape with circular base.

  The side wall 2 and the upper bottom 4 of the box coeport a continuous insulating material, yes present in Figures 2 and 3 references 21 to 25 and 40 This material can itself * n ^ me used to define the shape of the box , then having a

  sufficient rigidity, in particular to be casable.

  However, in a preferred embodiment

  profitable, the shape of the box is defined by a

  thin rigid envelope, preferably of synthetic material

  tick, which has the references 31 to 35 in FIG. 2.

  -6- We also see in Figure 2 that this side wall

  of the box has lateral extensions to the outside

  laughing 36 and 37, which are substantially coplanar at the edges

free from the box.

  In this preferred embodiment, FIG. 3 shows that the lower bottom of the box also includes a plastic envelope, designated

  generally by 39, and provided with a socket 60, suscep-

  tible to define outwardly a cell which will be described later in detail Above this lower bottom 39 is placed a deformable layer 43, this layer being capable of a bore 42 substantially in its center, and at the level of the pocket 60 Optionally, the drilling can be done in advance, or obtained by crossing

  of layer 3, as we will see later.

  As shown in Figures l A and 1 B, the boot is intended to be embedded in the wall M, its coplanar edges flush with the surface thereof, while the irons 10 of a frame of a floor P

  form an elbow 12, 13 around a vertical stud

  cal 5 engaged, through the bore 42 of the lower bottom of the boot, in the cell 6 of the wall, the assembly being secured to the pouring of concrete to the floor P on the formwork CP This allows a mechanical connection with -a

  excellent thermal insulation between floor and wall.

  For this, provision is also preferably made of an insulating layer IM at the level of the floor locations, this layer being incorporated into the inner face of the

  wall In FIG. 1B, the reference AM generally designates-

  ment the floor reinforcement, while the reference denotes spacers between several floor irons, which will give elbows 12 and 13 cooperating with the box according to the invention Figure 1 C illustrates the appearance of the devices after completion of the operations We see a stage of wall M, the insulation IM between the wall and

  -7- the floor, the floor itself P, as well as the bottom

  upper 4 of the box according to the invention.

  Figure 2 further shows that

  the cell 6 defined vertically in the wall M au-

  below the box has an oblong character in the longitudinal direction of the wall In association with the deformable nature of the layer of neoprene 43, this allows a relative clearance between the floor and the wall. For its part, Figure 3 shows in the upper part ,

  in the upper bottom of the box, a hole 41 homo-

  log 42, and allowing the vertical positioning of the stud 5 illustrated in FIG. 2, and around

  from which the elbows 12 and 13 will pass.

  We will now describe the implementation of a construction method according to the invention, starting from the support boot which has just been described. This method comprises the following operations:

  a) place from place to place in the walls M of the devices

  positive support 1, which we will consider here in the

  if they consist entirely of an envelope

  rigid cover, made of thin synthetic material, on which are added the lateral and upper insulating layer, as well as the lower layer of neoprene. This operation is carried out during the formwork of the wall, the fixing of the boot to the formwork being done using a stud, adapted to the inside of the box, and for example made of molded polystyrene or wood This stud is held in the boot by the threaded stud 5

  in the upper 41 and lower 42 holes (Figure 3).

  By inserting the stud in the box, it increases its rigidity.

  said, the thing being desirable when pouring the wall

well said.

  At the same time or shortly afterwards, another operation (b) is carried out consisting in setting up a? S O *? 73

  IM insulation layer, in the thickness of the wall, interior side

  laughing, this layer being located at the level of the

  contact cements between the floor and the walls.

  We can immediately see that the assembly can easily be made integral with the frame and the

  formwork of the wall, of which it then suffices to pour the concrete.

  After pouring the concrete, the stud 5 is removed, to

  extract the studs, which are then discarded.

  Within the AM reinforcement of the floor, which is still only defined by its lower formwork CP (figure

  l B), transverse elements 10 are placed, advantageous-

  ment joined to each other by spacers 11, and coming to define elbows 12 and 13 engaged in each of the boxes according to the invention We then replace the stud 5, inside the elbows 12 and 13 Figure 5 illustrates then the position of the auxiliary floor reinforcement 10 relative to the support boot, in a view

in horizontal section.

  It then remains to carry out the pouring of the concrete of the floor, which secures the stud 5 to the whole of the concrete of the floor with its reinforcement And the part of the concrete elements of the floor which enter into the hollow of each support box ensures mechanical connection with the wall, by pressing on the neoprene layer 43, the stud 5 also coming to engage in the cell 6,

  to ensure a better grip Of course, we

  will take special care in vibrating concrete in

each support zone.

  The present invention makes it possible to reduce considerably

  derably the heat losses between floor and wall, since there exists on the entire periphery of the floor a cut with high insulating power defined by

  IM layer of polystyrene or other insulating foam.

  At each press, the losses are reduced

  due to the use in support of neoprene plates.

  The dowelling of the floor on the wall maintains

  the relative position of the latter in the perpetual sense

  dicular to the wall plane, but it does allow horizontal differential variations on the wall plane, taking into account the oblong shape of the cell 6 The risks of cracking are therefore considerably reduced. Another advantage appears: traditionally, the pouring of a floor on a concrete wall leads to covering the edge of the floor, during the pouring of the latter, which constitutes a well-known site subjection The process of the present invention eliminates

  purely and simply this subjection.

  It will also be noted that the present invention

  tion offers a very simple structure, which only slightly modifies conventional construction operations: with regard to the pouring of the wall, the implementation of the invention simply supposes the addition of boxes at the locations provided, these boxes being able to be fixed by means of studs added inside

  and stud 5 to the frame of the wall or to its formwork.

  We immediately and without difficulty pose the

  IM peripheral insulating layer which can be immediate

  securely attached to the formwork, which allows

  very simply its insertion in the thickness of the wall.

  Finally, the outer envelope of the box, defined by the octagonal contour 31 to 35, the upper bottom 30, and the lower bottom 39 constitute a preferred means of implementation, being observed moreover that the addition

  from the socket 6 to the bottom bottom 39 allows

  immediately fix the oblong socket intended to receive the stud 5 during the subsequent casting phase

from the floor.

  as regards the pouring of the floor, it suffices to add to it a reinforcement of the conventional type, t ASOP? 7 Z 3 -10- which can be prefabricated, and corresponds to the references, 11, 12 and 13 in FIG. 1 B Engaged in the support boxes according to the invention, and after fitting of the stud, this reinforcement is then considered an integral part of the metal reinforcement of the floor,

  just run in the usual way.

  In practice, the detail characteristics of the box according to the invention may be the following: width between the edges 26 and 27, approximately 200 mm; depth between the interior plane of the wall and the bottom 31, approximately 100 mm; width of edges 35 and 36, about 20 mm; the bottom cell 6 is located about 50 mm from the inner edge of the wall, it has a width of 20 mm transversely to the wall, and a length of 30 mm in the axial direction of the wall; the holes 41 and 42 may have a diameter of approximately 20 mm; and the height of the box will be approximately 200 mm; the thickness of the IM insulating foam may be mm, this foam preferably being polystyrene; the internal foam of the box will also be 20 mm thick, and arranged continuously on the side walls and preferably also on the upper bottom of the box, this insulator preferably being, as previously indicated, a polyurethane foam , or else polyvinyl chloride; the neoprene plate placed at the bottom may have a thickness of approximately 10 mm; the downward projection which will be used to make the socket for the stud may have a depth of approximately mm; finally, the stud 5 can be produced by a round

concrete from 12 to 16 mm.

  -11- Of course, the above details are only given by way of non-limiting example, and those skilled in the art will understand that many variants can be produced without departing from the part of the present invention. In particular, it has already been indicated that instead of using a thin outer envelope, on which are added a foam insulating foam on the sides and at the top, as well as a neoprene plate at the bottom, we can make the walls lateral and upper directly by a rigid insulating foam, on which would be fixed for example by gluing the lower layer

neoprene.

  In addition, for certain applications,

  place of making the outer envelope in syn-

  aesthetic, it can be made for example from sheet metal

folded metal.

  In these different cases, the lower stud intended to produce the dowel of the stud may be defined either from the thin envelope, or from the

neoprene layer.

  In general, the attachments of the various elements may be made by gluing, or else by stapling, in particular as regards the attachment of the peripheral insulating layer IM to the edges

  26 and 27 of the box according to the invention.
