Description

Title of the invention: A through-system designed to be installed in a building to ensure the passage of a conduit between two floors technical field

[0001] The present invention relates to a through-system which is intended to be installed in a ceiling separating two floors of a building in order to reserve a volume for the subsequent passage of elements such as a duct, a flue in particular of chimney, etc. PREVIOUS STATE OF THE ART

[0002] During the construction of certain buildings, it is necessary to provide passages between floors, in particular for houses, in order to allow the subsequent installation of elements between floors such as a chimney flue to connect a combustion appliance with an external chimney.

[0003] The techniques currently implemented are not optimal and it is necessary to propose a system which facilitates the work of the manufacturer and subsequently the installer of the conduit. Description of the invention

[0004] An object of the present invention is to propose a through-system which is intended to be installed at the level of a ceiling separating two floors of a building.

[0005] To this end, a through-system is proposed for installation in a building ceiling, the through-system comprising:

[0006] - a chest having a base pierced by a window and side walls integral with the forming a base and delimiting an interior volume with it,

[0007] - a hollow cylinder, having a distal end and a proximal end which is attached to the base around the window, and the cylinder is positioned on the opposite side of the base relative to the side walls, and

[0008] - at least one plate housed in the interior volume.

[0009] Advantageously, the cylinder consists of a first sub-cylinder having the proximal end and a second sub-cylinder having the distal end and mounted telescopically relative to the first sub-cylinder.

[0010] Advantageously, the through-system includes a seal between the two sub-cylinders.

[0011] Advantageously, each side wall has first sections which delimit the interior volume and second sections which are foldable outwards opposite the interior volume.

[0012] Advantageously, the distal end has a rim. Brief description of the drawings

[0013] The features of the invention mentioned above, as well as others, will become clearer upon reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:

[0014] [Fig-1] is a perspective view of a through-system according to the invention,

[0015] [Fig.2] is a bottom view of the through-system according to the invention during its installation in place, and

[0016] [Fig.3] is a top view of the through-system according to the invention during its installation.

[0017] DETAILED STATEMENT OF IMPROVEMENTS

[0018] Fig. 1 shows a through-system 100 according to the invention and Figs. 2 and 3 show the through-system 100 installed in a ceiling 202 of a building 200. The through-system 100 is preferably made from shaped metal sheets.

[0019] The ceiling 202 is horizontal and separates two floors of the building 200 and as explained below, the through system 100 allows a passage volume to be reserved for example for chimney ducts.

[0020] The through-system 100 comprises a box 102 which is hollow and which has a bottom 102a which is arranged horizontally when the through-system 100 is in the operating position. The bottom 102a is pierced by a window 104, in particular circular.

[0021] The box 102 also includes side walls 102b-e which are integral with the base 102a and together with the latter define an internal volume 106 which is above the base 102a when the through-system 100 is in the operating position. The side walls 102b-e thus extend vertically from the base 102a and upwards relative to the base 102a.

[0022] In the embodiment of the invention presented here, the bottom 102a is rectangular and there are four side walls 102b-e, namely one per side of the bottom 102a.

[0023] The housing 102 also includes a hollow cylinder 108. The cylinder 108 has a distal end and a proximal end. The proximal end is integral with the base 102a and extends around the window 104 to define, together with the window 104, a channel through which elements, such as a conduit, can be passed. The cylinder 108 is further arranged on the opposite side of the base 102a from the side walls 102b-e, that is, below the base 102a. The axis of the cylinder 108 is generally vertical when the through-system 100 is in the operating position.

[0024] The chest 102 also includes at least one plate 110 which is housed in the interior volume 106 to fill it and cover the window 104. The plate(s) 110 are for example made of polystyrene.

[0025] During installation, the base 102a is placed on the beams 204 of the ceiling 202. In this method of installation, the diameter of the cylinder 108 is less than the dimensions of the base 102a so that the base 102a protrudes from the cylinder 108 and can rest on the beams 204.

[0026] The chest 102 and the plate(s) 110 are above the beams 204 while the cylinder 108 is below.

[0027] Hollow blocks 206 and mesh 208 are arranged on the beams 204 and the hollow blocks 206 and around the box 102, and the concrete of the floor of the upper floor is then poured on the hollow blocks 206 enclosing the mesh 208. The pouring of the concrete is carried out until the concrete is flush with the upper face 116 of the plate(s) 110, that is to say the face facing upwards opposite the bottom 102a.

[0028] A construction panel 210, such as a plasterboard panel, is fixed under the joists 204 and the floor slabs 206 to form the ceiling of the lower floor. The cylinder 108 is then hidden above the construction panel 210.

[0029] The through system 100 is then invisible and if necessary when a conduit has to be placed between the two floors through the ceiling 202, the plate(s) 110 are removed or cut to reveal the window 104 and the construction plate 210 is then cut inside the cylinder 108 to form a channel through the ceiling 202. The plate(s) 110 are thus removable.

[0030] Such a 100 through-system is thus easy to install and implement when needed.

[0031] The distal end comes against the construction plate 210 from the top of the latter, and to adapt the length of the cylinder 108 to the distance between the beams 204 and the construction plate 210, the cylinder 108 consists of a first sub-cylinder 108a having the proximal end and thus integral with the bottom 102a, and a second sub-cylinder 108b having the distal end and mounted telescopically relative to the first sub-cylinder 108a. According to a particular embodiment, the second sub-cylinder 108b is mounted to slide inside the first sub-cylinder 108a.

[0032] To achieve sealing between the sub-cylinders 108a-b, the cylinder 108 includes a seal, in particular a lip seal, which is disposed between the two sub-cylinders 108a-b. In the embodiment proposed here, the seal is mounted around the second sub-cylinder 108b and inside the first sub-cylinder 108a.

[0033] In the embodiment of the invention shown in [Fig. 1], each side wall 102b-e is divided into several elements, and thus comprises first sections 112a which delimit the interior volume 106 and second sections 112b which are foldable outwards opposite the interior volume 106.

[0034] The first sections 112a are thus relatively long in the horizontal direction and are integral with the bottom 102a.

[0035] The second sections 112b are relatively short in the horizontal direction and are also attached to the bottom 102a.

[0036] According to a particular embodiment, the first sections 112a and the second sections 112b are made by cutting from a single plate.

[0037] The second sections 112b are thus foldable outwards from the casing 102 as shown in [Fig. 1], where some of the second sections 112b have been folded. These second sections 112b thus form tabs which will be embedded in the concrete when it is poured, thereby ensuring that the through-system 100 is locked in position when in use.

[0038] According to a particular embodiment, the distal end has a rim 114 which allows the construction plate 210 to be fixed to the cylinder 108 and more particularly to the second sub-cylinder 108b, for example by means of fixing screws.

[0039] The rim 114 extends horizontally (parallel to the bottom 102a) on the outside of the periphery of the cylinder 108.
