Definitions

  • the present invention relates to the field of construction and in particular to the realization of junctions between concrete vertical parts such as facade walls and horizontal concrete parts such as slabs.
  • the present invention relates to the formation of a reservation during the realization of this junction.
  • thermo bridge Devices to reduce heat loss have been proposed and generally consist in ensuring the continuity of thermal insulation by the interposition of an element called “thermal breaker” in the form of an insulating element and which ensures the continuity of the interior insulation with only a few ad hoc anchors, thus preserving the stability of the structure.
  • the traditional solution consists first of all to realize the veil of vertical frontage by stopping it at the lower level of the slab, then to place the thermal breaker in its place, to form the edge of the slab and to realize the slab of the side of the breaker, and finally to realize the end of sail to the upper level of the slab. It is then possible to remove the edge of the slab and make the last part of the facade of the upper floor and this by starting the entire process on each floor. It is observed that the fact of placing a thermal breaker requires the realization of the façade veil in several phases with successive concreting stops, which of course requires not only the use of small quantities of concrete but also an increased labor force. and therefore longer run times and additional costs.
  • the document FR-2644823 describes a system that partially offers a solution to the problems identified above. It is a device and a process for obtaining peripheral rest of the slabs and slabs of reinforced concrete. The rest is obtained by the installation of several adjacent blocks on a horizontal surface secured to the formwork. This system makes it possible to obtain a reservation serving as slab rest, with a single step of pouring concrete.
  • the system presented in the document FR-2644823 does not use thermal breakers as described above. The use of these thermal breakers requires in fact to provide a sufficient depth of the reservation to place the reinforcements of the breakers that will be embedded in the concrete on the side of the veil. Using the system of FR-2644823 , the space between the blocks and the formwork would become too narrow to ensure efficient casting of the concrete.
  • the present invention aims to provide a solution that allows concreting in a single phase while allowing to have a thermal breaker.
  • the present invention also aims to ensure easy concreting, neat and which does not require having to work in the precipitation.
  • the present invention also aims to provide an elegant system that does not increase production costs or the ability of laying workers.
  • the present invention relates to a device and a method as described in the claims.
  • the present invention relates to a device in the form of a longitudinal box allowing the formation, in a vertical concrete veil, of a continuous horizontal reservation intended to support a horizontal slab during the production of concrete structures, characterized in that the device comprises at least one movable portion sliding in the longitudinal direction in a fixed part, for increasing the volume of the box by deployment or extension.
  • the device is in the form of a parallelepiped box.
  • Other longitudinal shapes, such as cylindrical boxes, could also be used.
  • this box comprises at each of the lateral ends of the fixed part a sliding part.
  • each of the sliding parts has a length corresponding to half the length of the fixed part of the box so as to double the initial volume when extending or deploying the sliding parts out of the fixed part. It is obvious that said length of the sliding parts must not correspond mathematically to half the length of the fixed part. Said length of the sliding parts thus corresponds to about half the length of the fixed part, so as to practically double said volume.
  • At least a portion of one of the preferably longitudinal faces of the box is not completely closed so as to allow the placement of fastening means of said box to the formwork elements on which it will become solid.
  • the fixed portion is formed by a parallelepipedal space open at the lateral ends and preferably open on one of the longitudinal faces, while the sliding parts are designed as a drawer, preferably without bottom.
  • handles will be arranged on the sliding parts.
  • the material for producing the sliding portion is plastic, wood and / or metal.
  • the material for making the fixed part may be plastic or other synthetic material (eg resin), wood and / or metal.
  • the dimensions of the box and in particular the lateral width is between 3/4 and 1/2 and preferably close to 2/3 of the total width available in a formwork element.
  • the devices are arranged along the length of the web such that two successive devices come into contact with each other when the adjacent sliding parts have been slid or slid.
  • the present invention is particularly useful for the formation of a reservation for the installation of a thermal breaker at the junction of the facade / slab.
  • the present invention relates to a method wherein, to fill the formwork up flush with the lower level of said devices, the concrete is poured into at least one space between two non-extended or non-deployed devices.
  • the present invention relates to the use of a device as described above for the formation of this reservation for the installation of a thermal breaker at the junction facade veil / slab.
  • the figure 1 schematically describes the problem of the junction between a vertical part and a horizontal part which allows the installation of a thermal breaker.
  • the figures 2 describe schematically the device according to the present invention in the sliding position (deployed).
  • the figures 3 describe the constituent elements of the device according to the present invention being in the form of a longitudinal parallelepiped box and which allows the formation of a reservation during the realization of this junction.
  • the figure 4 describes a fastening means of the device according to the invention, used against the face of a formwork of the facade wall.
  • FIGS. 5a-5c , 6a-6b and 7a-7b describe the principle of laying the device according to the present invention according to a method of forming a reservation during the realization of this junction.
  • the present invention relates first of all to a device in the form of a longitudinal parallelepipedic box allowing the formation of a reservation during the production of concrete structures, characterized in that comprises at least one sliding part in the longitudinal direction in a fixed part, making it possible to increase the volume of the box.
  • the figure 1 describes the problem that arises when producing concrete structures that requires the junction between a horizontally disposed slab and a frontage or facade veil disposed vertically.
  • the vertical veil of the facade being continuous, it can not have an interior insulation over the entire height, this interior insulation being interrupted to the right of the slab, and this over the entire length of the vertical facade and likewise on any the periphery of the building.
  • thermal breaker a device has been proposed called "thermal breaker" which allows to recreate the continuity of the inner insulation.
  • the façade veil (1) is made by stopping it at the lower level (2) of the upper slab (5). Then, we put the thermal breaker (3) and we lock the edge of the slab (4) so as to realize the slab on one side (5) of the breaker and the end of the sail on the other side (6) until at the upper level (7) of the slab. Thus, it is possible to remove the edge of the slab and make the façade veil to the upper floor. This can be repeated on each floor. It is observed that this way of working requires successive concreting stops at the lower level (2) and the upper level (7).
  • the present invention is simply to propose to realize an outer formwork of the facade veil to the upper level (7) directly in a single phase, creating a reservation having a suitable depth to serve as a support for the slab, provided with thermal breakers .
  • the figure 2 schematically shows in section a device in the form of a longitudinal parallelepipedal box 15 and which consists essentially of two parts: a fixed part (12) and a movable portion (13).
  • two moving parts are present at each end of the fixed part.
  • the dimensions of the fixed and movable parts are calculated so that the movable part or parts slide or slide easily in the fixed part.
  • the fixed and mobile parts are represented in Figures 3a and 3b with their respective ratings (12,13).
  • the figure 3c shows a perspective view of the device.
  • the fixed part 12 is essentially an element having three faces and constituting a longitudinal parallelepiped whose lateral parts are open, thus allowing the placement of a sliding element 13 (moving part) being essentially in the form a drawer, that is to say a parallelepipedic box whose at least one side face 16 is closed or closed.
  • handles (14) can be arranged on each of the moving parts.
  • each movable part will preferably be of the order of half of the fixed part, so that in the folded (undeployed) position, each of the two moving parts can easily integrate with the fixed part and that In the extended or deployed position, the planned volume is practically doubled.
  • At least one of the longitudinal faces of the parallelepiped of both the fixed part and the sliding part is free or open, so as to allow the placement of fastening elements and in particular magnetic fastening elements (in the case metal forms).
  • These fasteners are designed so as to allow the attachment of the device to the formwork.
  • magnets that have a shape as represented in figure 4 .
  • These magnets 17 are installed inside the fixed part 12 of the box 15. Their shape is adapted to the dimensions of this fixed part.
  • These magnets are provided with flexible elements such as springs 18, which push the magnet against the face of the formwork 20.
  • the folded portions 19 of the fixed part 12 serve as support for the magnets.
  • the Figures 5a-5c represent the different steps for laying said box.
  • said caissons 15 are placed on the internal part of the formwork 20 of the veil by means of suitable elements, and this at the level of the placement of the horizontal part of the slab ( Fig. 5a ).
  • the vertical concrete formwork is filled in, preferably by pouring the concrete into at least one of the spaces between two non-extended or non-deployed caissons, up to the level of the lower level 21 of said sliding device ( Fig. 5b ).
  • the moving parts 13 of said device are slid or slid so that the moving parts of two adjacent devices come into contact, so as to form a single volume.
  • the said concreting phase is completed by filling the free space 22 present between the formwork 20 and the various devices 15 which are arranged in the extended or extended part of the formwork ( Fig. 5c ) and after drying, simply remove the successive devices, creating a reservation.
  • the Figures 6a-6b show a sectional view of the placement of the device 15 vis-à-vis the veil 1.
  • the figure 6b shows the result after removing the device, thereby creating the reservation 10.
  • the slab 5 is cast which rests on the reservation 10, thermal switches 3 being put in place, and finally we end by pouring the next part of the vertical veil 1.
  • the Figures 7a and 7b represent several devices arranged next to each other.
  • the figure 7a is a plurality of devices arranged with an interval which, when the moving parts in drawer form are deployed or extended, come into contact with each other. In fact, the "left" part of a first device comes into contact with the "right” part of the adjacent device. As represented in figure 7b it is thus possible to create a continuous reservation (10) which extends essentially over the entire width of the web.
  • the size and in particular the width of the sliding device will be chosen so as to make a reservation 10 between 3/4 and 1/2 of the width , thus leaving a sail portion 22 between 1/4 and 1/2 of the total width at the reservation.
  • the width of the sliding device is of the order of 2/3 of the width of the web, that is to say between 12 and 13 cm.
  • the length of the fixed part of the sliding device can be several meters.
  • the main advantage of the device of the invention and the method of use is observed especially when the width of the portion 22 must be minimal, because of the length of the reinforcements forming part of the thermal breakers.
  • a maximum length of the reinforcement portion 23 embedded in the concrete side of the veil will ensure the stability of the slab.
  • the device of the invention thus makes it possible to cast the concrete rapidly and efficiently in two phases: firstly between the non-extended or non-deployed devices, and then (after expansion or deployment) between the extended or deployed devices and the formwork (thus filling the narrow space 22). Because of the large dimensions of the free spaces between the non-extended or non-deployed devices, the first phase is carried out very quickly and makes it possible to obtain an optimal quality of concrete. By using static devices (which can not be deployed or extended), one would have to pour all the concrete through the narrow space 22, which would be inadequate in terms of efficiency and would have repercussions on the quality of the concrete. dried veil.
  • the various fixed and moving parts of the device must not be made of the same material. They can be made of metal, plastic or other synthetic material such as resins, or even wood. This will depend mainly on local construction habits.
