Description

Title of the invention: AIR SUPPLY AND / OR AIR EXTRACTION INSERT FOR DRYING AN INSULATION AND WATERPROOFING COMPLEX AFTER A DISASTER technical field

[0001] The invention relates to the field of drying (or dehumidification) of an insulation-sealing complex after a disaster such as water damage or a flood.

[0002] It relates more particularly to an air supply and / or extraction insert, as well as a drying system for an insulation-sealing complex and also to a drying process for an insulation-sealing complex using said insert.

[0003] The invention finds applications, particularly in the building industry, and more specifically in the field of thermal and / or acoustic insulation and waterproofing of building structures. These may include individual or multi-family residential buildings, industrial, agricultural, or commercial buildings, and more generally all other constructed buildings. Flat roofs comprising an insulation and waterproofing system that may be subject to damage resulting in water penetration into the system at the level of a roof slab are particularly relevant. However, the invention applies more generally to other horizontal structures such as floor slabs between different levels (staircases) within a building, or to vertical structures such as double walls or insulated partitions. Prior art

[0004] In buildings with a flat roof, for example, the roof slab (i.e., the upper slab of the highest level) can be covered with one or more layers of thermal insulation material (called "insulation" for short) covered with one (or more) layer(s) of waterproofing material intended to protect the insulation and prevent water infiltration, particularly from rain, into the underlying slab and ultimately into the entire building.

[0005] A loss involving water penetration is, for example, water damage resulting from damage to or wear of a waterproofing membrane which causes said membrane to lose all or part of its effectiveness against rainwater, or from total or partial flooding of the structure following natural weather events or the A burst water pipe (whether a domestic water supply pipe or a wastewater or rainwater drainage pipe), or any other similar cause, can lead to moisture buildup. High moisture concentration within the insulation can cause mold growth, corrosion of structural elements, rot, and reduced thermal performance.

[0006] In the type of applications envisaged, drying by blowing in dry air and extracting humid air is carried out to reduce and, if possible, eliminate the humidity of a confined space such as a plenum filled with insulation material (thermal and / or acoustic), or the volume of an insulation-sealing system. A drying procedure can be implemented, in particular, to restore the performance of thermal and / or acoustic insulation in order to avoid the need for its replacement. The procedure consists of introducing dry, warm air into the space to be dried in certain areas by blowing air into the space, while simultaneously extracting the humid air from other areas of the space by blowing air, until a residual humidity level in the extracted air meets a predetermined target.

[0007] To date, the methodology used consists of installing a dry air unit (dehumidifier or desiccant) coupled to a blower turbine. Cores are then drilled into the waterproofing membrane, and "blowing inserts" (available, for example, from the German company DÔLCO) are installed for the duration of the drying process. The units are then connected to the blower inserts via flexible ducts. Dry, warm air is then forced under pressure into the insulation-waterproofing system. This air becomes saturated with moisture in the confined space through which it circulates. The humid air, that is, the moisture-laden air removed from the insulation, is then exhausted through natural openings or previously installed ventilation vents. The duration of the drying procedure is determined by the operator's judgment and is generally about three weeks.Once the procedure is complete, the inflation nozzles are removed and the core holes must be resealed.

[0008] It is desirable that the supply and extraction of air be controlled on the basis of information provided, in particular, by temperature sensors, humidity sensors and / or pressure sensors of the air being supplied and / or the air being extracted, and if possible also according to the temperature and humidity of the ambient air.

[0009] Indeed, measuring and comparing different parameters of the supply air, the exhaust air, and possibly the ambient air, makes it possible to objectively validate the completion of the drying operation. Thus, for example, The operation can be considered validly completed once the moisture levels within the insulation and waterproofing system return to the expected levels, as specified, for example, by applicable standards or regulations. The ability to provide objectively verified validation of the drying process's completion makes it easier to demonstrate the value of the drying service to building owners, technical building experts, and insurers. This can prevent the need to redo the entire insulation and waterproofing system.

[0010] Despite its high cost and significant environmental impact, a complete overhaul of the insulation-sealing system is indeed generally the rule, in order to ensure a perfect restoration of the original performance for the insulation of the structure (whether thermal and / or acoustic), and in order to protect the insurer from the risk of a new warranty claim from the owner for the consequences of the same loss.

[0011] Recently, the complete replacement of the insulation and waterproofing system has become even more complicated and costly with the trend towards the widespread installation of equipment on flat roofs, such as photovoltaic panels and / or green roofs. Indeed, the project to replace the insulation and waterproofing system must begin with the dismantling of the installed equipment and fixtures, which must be stored for the duration of the drying process and then reinstalled after the process is complete.

[0012] US20160244962 A1 discloses various technical considerations for drying parts of a building (room, floor, wall, and / or roof) by supplying / extracting air into an insulated plenum. In particular, the document discloses the use of hot and / or dry air injection inserts and humid air extraction inserts installed through a waterproofing membrane to dehumidify the plenum. It also discloses a control of air supply / extraction means based on information provided by sensors (temperature, humidity, and / or pressure) of the supply air, the extracted air, and / or the ambient air. It is further taught that the integrity of the isolation plenum can be preserved by favoring the extraction of humid air by creating a vacuum in an extraction tube, rather than an overpressure in the plenum into which hot and / or dry air is injected.The disclosed air gap inserts each include a threaded end that is screwed in either with a nut and washer that clamps from below a plenum cover layer, or directly into the sealing assembly. Finally, the document explains that, after the drying process, the injection and extraction inserts can be used to seal the holes that have been made in the lining. of sealing and in which said inserts have been placed. It is thus indicated that the seal can be restored by using a liquid filling material which can begin to solidify during the passage of the insert, instead of flowing directly and spreading inefficiently in the plenum before solidifying.

[0013] A drawback of the air supply or exhaust inserts disclosed in this document is that they themselves exhibit poor sealing at the interface with the insulation-waterproofing system. This can lead to further water ingress into the plenum during the drying process, particularly in inclement weather. Furthermore, the operation described above, which is proposed to be implemented after the drying procedure using a liquid-phase sealant that must solidify to make the inserts airtight and / or plug the holes made in the insulation-waterproofing system's coating for the purposes of the drying procedure, is difficult to implement and unreliable.

[0014] Other similar aerodynamic inserts are disclosed in document DE4344851 Al and document EP3953535 Al, and also present the same disadvantages with respect to the sealing of the complex to be treated, at the level of their point of implantation. Description of the invention

[0015] The invention aims to remedy at least in part the aforementioned disadvantages of the prior art.

[0016] To this end, the object of the invention is an air supply and / or extraction insert for supplying or extracting air into an insulation-waterproofing system of a building comprising at least one layer of insulation material covered by an external waterproofing membrane, as part of a drying procedure for said system, the insert being made up solely of: • a substantially flat plate comprising at least one through-air passage formed through the plate, for example substantially at the center of said plate; and • a tubular sleeve with an air passage duct extending from a first determined face (for example the upper face) of the plate, around and in line with the air passage orifice substantially perpendicular to the plane of the plate and away from said first face of said plate, in which: • The plate is designed to be positioned with its second face (for example, the underside), flat on the waterproofing membrane of the system to be dried. with the air passage opening aligned with a core hole drilled in said cladding in order to expose the layer of insulation material of said assembly; • a minimum distance is provided between an outer wall of the tubular sleeve and the peripheral edges of the plate (i.e., between the outer wall of the sleeve and the points closest to the perimeter / periphery of the plate), so that the first face of the plate is adapted to receive a sealing coating bonded partly to the plate and partly to the sealing coating of the assembly, straddling and overlapping the boundary between said plate and said sealing coating at said peripheral edges of the plate, said minimum distance being defined for example by applicable technical specifications; • the tubular sleeve is terminated, at its free end opposite the air passage orifice formed in the plate, by an air connection fitting adapted for connecting an air circulation duct to the air insert during the drying process; and, • The tubular sleeve includes an associated removable closure cap, which is suitable for hermetically sealing the sleeve to allow the aerodynamic insert to be left in place at the end of the drying process.

[0017] Thus, embodiments of the invention rely on improved sealing of the air duct inserts, which can be used for supplying dry air and extracting humid air. Indeed, their design allows the base to be partially covered, at its peripheral edges, by a conventional sealing coating that is applied after the insert has been operationally installed but before the drying procedure begins, under the responsibility and with the guarantee of a professional in the field of sealing (i.e., a roofer), in compliance with the applicable technical specifications. Such specifications are determined, for example, in France, by the applicable Unified Technical Document (DTU), namely DTU 43.1 in its version in force on the date of filing of this patent application.This document is established by the General Commission for Building Standardization / DTU (Unified Technical Document), and is available from the Scientific and Technical Center for Building (CSTB), which provides the Commission's secretariat. Professionals will understand that the application of such a DTU, regardless of its status or nature, results from an agreement between the project owner and the contractor responsible for a works contract related to the building in question. In the context of implementing the invention, the aforementioned DTU, or any other DTU, is therefore binding only on the signatories of the relevant drying contract who have adopted it. introduced, where applicable, as a contract element, thus giving it the character of a contractual obligation. Nothing in this document implies a legal or regulatory obligation to use tools, equipment, or accessories meeting specific technical requirements of this nature.

[0018] According to one advantage, after the drying process is complete, the air duct inserts can be neutralized from an airtightness standpoint so that they can be left in place (one might say "abandoned") for possible future reuse. This neutralization does not require a further visit from a sealant technician, as it simply consists of installing a removable, airtight sealing plug on the connection fitting provided at the free end of the air passage tube of the air duct insert. This airtight sealing plug is associated with the connection fitting of the tube. In other words, it is functionally an integral part of the air duct insert, even though it is removable and is, of course, removed from the connection fitting during the drying procedure to allow the connection of an air line to said fitting.

[0019] In embodiments: • The air connection fitting can be a Cam-Lock™ type connector, namely: • either a male connector such as a Cam-Lock™ plug type A, E or F, • either a female connector such as a Cam-Lock™ type B socket, CouD, • and the associated removable cap is then: • a DC-type Cam-lock™ cap, or • a DP type Cam-lock™ plug, respectively.

[0020] Cam-Lock™ (or Cam-Lock™) type fittings (or couplers) are advantageously often made of stainless steel and are widely used in all types of industries, and therefore inexpensive. They are simple to connect and disconnect without the need for tools. They employ quick-connect male and female connectors of the grooved and cam type. A male connector includes a Cam-lock™ type E (for push-fit pipe connection), F (screw-on, with male thread), A (screw-on, with female thread), or F-AS (weld-on) connection with an annular groove. A female connector includes a Cam-lock™ type cam-on connection sleeve with locking levers, of type C (for push-fit pipe connection), B or B-AS (weld-on), or D (screw-on). The use of a gasket between the two male and female connectors ensures a leak-proof connection. The seal can be made of Polytetrafluoroethylene (PTFE, known as the term Teflon™), for example. The airtight sealing cap placed on the connecting end of the tubular air passage sleeve at the end of the drying process, and which is adapted to seal the connecting end to the free end of the sleeve, can then be, for example, a Cam-Lock™ DC type (female) cap or, for example, a Cam-Lock™ DP type (male) cap, depending on whether said connecting end is a Cam-Lock™ plug (male connector) or a Cam-Lock™ socket (female connector), respectively.

[0021] In some embodiments, the tubular sleeve includes a removable, associated filling sprue made of insulating material, which is shaped and sized to fill the air passage in the tubular sleeve. Preferably, the filling sprue is made of a dense material, such as extruded polystyrene (or XPS), for example, which is easy to handle. The sprue can be inserted into the sleeve from the top of the sleeve after the drying process has been completed and the air duct that was coupled (or connected, or plugged) to the sleeve via its connection fitting has been uncoupled (or disconnected, or unplugged), and before the sleeve is closed with the airtight sealing cap. This also eliminates the risk of thermal bridging on the surface of the insulation-sealing assembly.Like the aforementioned closing cap, the carrot is functionally an integral part of the air insert, even though it is removable and is of course removed from the sleeve during the drying procedure in order to allow the circulation of the air supplied or extracted through said insert.

[0022] In further embodiments, the air connection fitting and the associated airtight sealing cap of the tubular sleeve may include means for receiving together a single-use tamper-evident seal affixed to indicate any unauthorized removal of said cap following the drying process. Such a seal may be a retractable cable, made of plastic resin for example, of variable length, fixed length, or of the padlock type. A metallic seal may be made of stainless steel wire or galvanized wire. These wires may be passed through the locking mechanism of the Cam-Lock™ fitting, for example, through loops provided at the ends of the levers, such that the levers cannot be lifted to unlock the fitting without breaking the seal.Alternatively, it could also be a bolt seal, more expensive but offering a higher level of protection, which consists of two metal parts designed to interlock via a locking mechanism. An even more expensive option is an electronic seal, generally reusable, which generates a time, date, and unique number each time the seal is closed and opened, this information allowing for the recording and logging of all events.

[0023] Certain preferred but not limiting aspects of this process are the subject of dependent claims.

[0024] According to a second aspect of the invention, a drying system for an insulation-sealing complex of a building structure is also proposed, comprising one or more air inserts according to the first aspect above to ensure the blowing of air into the complex and / or the extraction of air from said complex.

[0025] In some embodiments, the drying system may further include one or more connection accessories, • said connection accessories being suitable for connection between themselves, and / or to the air inserts, and / or to a dry air supply subsystem and / or to a humid air extraction subsystem of the system, where appropriate via one or more manifolds of the system, of dry air supply ducts and / or of humid air extraction ducts of the system; • each connection accessory comprising a portion of straight tube forming a straight fitting or several non-collinear portions of straight tube forming an angled fitting, or a "T" shaped or a "U" shaped fitting, for example, some portions of which are equipped with one or more sockets for the installation of at least one hygrometric sensor of the system, such as a temperature and / or humidity sensor for example, or for the installation of at least one pressure gauge or vacuum gauge of the system for measuring parameters of the air circulating in the fitting including temperature, humidity, pressure and / or vacuum of the air; • at least one connecting accessory being terminated at at least one of the free ends of one of the straight tube portions, by a connecting element complementary to the connecting element of the tubular sleeve of the aerodynamic insert.

[0026] Sensors in the system are used for monitoring and controlling the system, which can be done automatically or under the supervision of an operator remotely or on-site. Recording the measurements taken during the drying procedure, and presenting them, for example, in an intervention report issued at the end of the process, makes it possible to demonstrate to any interested third party that the drying operation was effective and that the expected result was achieved.

[0027] According to yet a third aspect, a method of implementing the aerodynamic insert according to the first aspect of the invention is proposed, for example within a drying system of an insulation-sealing complex according to the second aspect above.

[0028] The process can mainly be applied to roof insulation and waterproofing systems for buildings, and in particular for flat roofs (roof terraces), but it It can also be used for insulated concrete slabs inside buildings, such as inter-story slabs. In all these applications, the insulation and waterproofing system to be treated is essentially horizontal. However, the process can also be used for drying systems extending almost vertically, such as certain wall linings or drywall partitions. More generally, the process is applicable for drying parts of a building structure (room, floor, wall, and / or roof) and all other types of confined spaces that have suffered water infiltration or flooding.

Detailed description

[0030] In the figures and throughout the description, the same reference numerals represent identical or similar elements. Furthermore, the various elements are not drawn to scale in order to enhance the clarity of the figures. Moreover, the different embodiments and variants are not mutually exclusive and may be combined.

[0031] In what follows, the terms "approximately", "around", or "in the order of" mean within 10%, and preferably within 5%. Furthermore, the terms "between ... and ...", or equivalent terms, mean that the bounds are inclusive, unless explicitly stated otherwise.

[0032] Air is a gaseous mixture composed of nitrogen (approximately 78% by volume), oxygen (approximately 21% by volume), and traces of other gases (argon, carbon dioxide, hydrogen, helium, krypton, xenon). In addition, air contains suspended water molecules in the form of water vapor or humidity. In physics, air containing no trace of humidity is called dry air, while air containing 100% humidity is called saturated air.

[0033] The absolute humidity (AH) of an air mass represents the quantity in grams (g) of water vapor present in a given volume of dry air (namely 1 m³). Its value, expressed in g vapor / m³ dry air, remains constant even if the air temperature varies, while remaining above the dew point temperature, that is, the temperature at which the water vapor in the air begins to condense. Water vapor in an air mass is invisible. However, if dry air becomes saturated with humidity beyond a certain limit, fog and condensation appear, as the water forms droplets suspended in the air that become visible to the human eye: the air is then said to be saturated.

[0034] Furthermore, relative humidity (RH) is the ratio (expressed as a percentage, %) between the amount of water contained in the air (absolute humidity) and the maximum amount it can hold at a given temperature before condensation. Temperature variations directly influence relative humidity. More precisely, relative humidity decreases when the temperature rises and increases when the temperature falls.

[0035] Dry air, as defined by the scientific definition above, exists only under laboratory conditions and is not generally encountered in real life. Indeed, except in the very specific case of an extremely desert climate, ambient air always contains some moisture. Therefore, in what follows, the expression "dry air" used in reference to air blown into an insulation-sealing system means air with a relatively low moisture content, for example, air with a relative humidity (RH) of less than 40%.

[0036] Finally, a three-dimensional orthogonal (X,Y,Z) direct frame of reference is defined here and for the remainder of this description, where the X and Y axes form a plane parallel to the principal plane of the surface of a given constructed structure, for example, the horizontal plane for a flat roof or an inter-story slab of a building, and where the Z axis is oriented substantially orthogonally to said principal plane, this Z axis being oriented along the direction of the axis of gravity. In the remainder of this description, the terms "vertical" and "vertically" are understood to refer to an orientation substantially parallel to the Z axis, and the terms "horizontally" and "horizontally" to refer to an orientation substantially parallel to the (X,Y) plane.Furthermore, the terms "above" and "below" and derived terms or expressions (such as "above" and "below", or "over" and "underneath"), as well as the terms "lower" and "upper", which are used to qualify an element of the constructed structure under consideration, are understood to be relative to an increasing positioning when moving away from the structure upwards, i.e., along the vertical direction +Z.

[0037] The terms "roof terrace" or "rooftop terrace" refer to a roof with a flat slope (less than 1%) or a shallow slope (between 1% and 5%). Rooftop terraces may or may not be designed for pedestrian traffic, possibly combined with a living area. Generally, pedestrian traffic is due to the presence of equipment or installations on the roof requiring frequent human intervention (for maintenance, etc.). Such equipment includes, for example, air-cooled condensing units (for air conditioning in rooms located below the roof), devices for cleaning facades (particularly glazed facades), photovoltaic panels, elevator or freight elevator machinery rooms accessible exclusively from the rooftop terrace, etc. "Living area" refers to the presence of static loads other than those related to the aforementioned pedestrian traffic.Some roof terraces (called "garden roof terraces") include one or more planted areas that receive vegetation (grass, shrub and / or flower plantings, etc.).

[0038] A waterproofing-insulation system is defined as a structure that performs both waterproofing and insulation functions simultaneously within a multilayer assembly. Such an assembly comprises at least one layer of thermally and / or acoustically insulating material (or insulation layer, or insulating layer), and at least one layer of a waterproofing membrane (or waterproof layer, or sealing layer). The insulation layer(s) may, for example, consist of insulating panels, such as polyurethane or polystyrene panels (which are most commonly used), or cork panels, for example, or other plant fibers such as hemp fibers. They may also comprise loose flakes of such a material of plant origin (particularly hemp) or animal origin (for example, sheep's wool), applied in bulk, and more or less bound and / or compacted, if necessary.Examples of waterproofing coatings include, but are not limited to, asphalt and two-layer systems based on elastomeric modified bitumen membranes commonly referred to as "SBS two-layer bitumen" (where the acronym SBS stands for "styrene butadiene styrene", and designates a type of synthetic plastic that gives these bituminous membranes high elasticity).

[0039] In the following description of embodiments of the insert and the system, as well as of methods of implementing the process, reference is made to the simplified diagram in [Fig. 1] to the non-limiting example of a drying system 1 used for post-disaster drying of an insulation-waterproofing assembly 101-102 installed on a roof terrace slab 100, for example a concrete slab. The insulation-waterproofing assembly 101-102 comprises one (or more) layer(s) of insulating material 101 (simply referred to as "the insulation" for short), faced on top with a Waterproofing membrane 102. Waterproofing membrane 102 can be single-layer or multi-layer, which is why, for the sake of brevity, professionals generally refer to it as "single-layer" or "multi-layer." The waterproofing membrane can be bonded to the insulation and / or the concrete slab (usually with waterproofing upstands not shown), for example, by hot bonding if the waterproofing membrane is bituminous. Alternatively, it can be unbonded (also called "non-adhered") when a heavy protective layer is placed above the waterproofing membrane (for example, paving slabs on pedestals, gravel, vegetation, etc.).

[0040] A first step in the process consists of installing air vents 10a-10b, distributed over the entire surface of the roof terrace 100. A first vent or group of vents 10a is provided for supplying dry and / or warm air into the insulation and waterproofing system 101-102 to be dried. A second vent or group of vents 10b is provided for extracting the air that has become saturated with moisture from the system, thus producing the desired drying effect. In one embodiment of the system, the vents 10a and 10b are structurally identical and differ from each other only functionally, in their use, as described above.

[0041] The inserts 10a and 10b are arranged by an operator to cover the area of ​​the roof terrace to be treated. This spatial distribution relies on the operator's expertise and experience, based on a prior analysis of the characteristics of the drying procedure to be carried out. The number and distribution of the supply air inserts 10a and the number and distribution of the extraction air inserts 10b depend on the size and shape of the area to be dried, the composition of the insulation-waterproofing system, and in particular the nature and thickness of the insulation layer, as well as the extent of the moisture affecting the system as assessed beforehand, and also any requirements for the speed of the process, etc.All this knowledge makes it possible, in particular, to calibrate the number and distribution of the supply inserts 10a and the extraction inserts 10b according to the needs of the drying procedure to be carried out. Of course, at least visual identification of the two types of inserts, such as a colored marker or any other form of physical or electronic labeling, can make it possible to distinguish the supply inserts 10a from the extraction inserts 10b, in order to avoid errors during their connection.

[0042] The second step of the process is the installation of machines for supplying dry and / or hot air via the supply inserts 10a, and machines for extracting humid air via the extraction inserts 10b. In one embodiment, the former are grouped in a first supply equipment or subsystem 20a, while the second set is grouped in a second extraction unit or subsystem 20b: • The supply subsystem 20a comprises a dehydrator 21a coupled to a turbine 22a connected for supply, which is associated with a thermo-hygrometric probe (not shown) allowing the measurement of the various parameters of the supplied air; and • The extraction subsystem 20b includes a turbine 22b connected in suction, coupled to a water separator 21b which is associated with a thermo-hygrometric probe allowing the measurement of the different parameters of the extracted air.

[0043] The air dryer can, for example, be a dehumidifier, i.e., an air-to-air heat pump which, like an air conditioner, lowers the air temperature to condense the water particles with a radiator (or condenser) in order to separate them from the air. Alternatively, the air dryer can be a desiccant dryer, which comprises an endless wheel made of silica gel (i.e., a silica gel with moisture-absorbing properties) through which the humid air passes, while approximately one-quarter of the wheel is bordered by a hot air duct that extracts the moisture from the wheel. The high dehumidification capacity can reach several liters of water per day (e.g., about ten liters / day), even at temperatures as low as +0°C. The airflow can be several hundred cubic meters per hour (e.g., about 200 m³ / hour).The 22a and 22b turbines can have several ventilation modes or speeds (e.g., low ventilation, medium ventilation, or high ventilation), one of which is selected to optimize air circulation in the space to be dehumidified.

[0044] Those skilled in the art will appreciate that when water (in liquid form) is trapped in the insulation-sealing system, pumping can be carried out prior to the actual drying procedure by blowing in dry air and extracting humid air, via the suction turbine 22b coupled to a water separator, and that this pumping can be carried out via all or some of the blow-in inserts 10a and / or the extraction inserts 10b. Advantageously, this water pumping can also be carried out automatically and simultaneously from the start of the drying procedure with the system as proposed herein.

[0045] The third step of the process consists of connecting the supply subsystem 20a to the supply inserts 10a via the air ducts, and connecting the exhaust subsystem 20b to the exhaust inserts 10b via the air ducts. These connections are made via a supply duct network 30a and an exhaust duct network 30b, respectively: • the supply line network 30a may include supply lines 30a which connect each of the supply inserts 10a to the supply subsystem 20a, either directly or via one or more supply manifolds 32a; and, • The extraction duct network 30b may include extraction ducts or conduits 30b which connect each of the extraction inserts 10b to the extraction subsystem 20b, either directly or via one or more extraction manifolds 32b.

[0046] The dry air supply ducts 30a and the humid air extraction ducts 30b can be flexible ducts, for example corrugated ducts, possibly joined together by connecting accessories, namely straight fittings allowing the assembly of duct elements of determined length to reach inserts that are relatively further apart, and / or elbows at a determined angle (for example, 90°, 135°, etc.) allowing the configuration of a rational duct route while avoiding the risk of pinching a flexible duct at the point of a change in the direction of extension of a duct induced by the topology of the roof terrace.

[0047] According to some embodiments, the proposed system 1 may include connecting elements for connecting dry air supply ducts 30a and 10b to each other and / or to the air inlets 10a and 10b, and / or to the manifolds 32a and 32b, and / or to the subsystems 20a and 20b, and to the humid air supply ducts 30a and 30b, respectively. At least some of these connections may be equipped with one or more sockets for installing a hygrometric sensor (temperature and / or humidity sensor), or for installing a vacuum gauge. Examples of such system accessories will be described below with reference to [Fig. 5] and [Fig. 6].

[0048] The fourth step consists of carrying out the actual drying process. In this step, the blow-in sub-assembly 20a and the extraction sub-assembly 20b are put into operation in order to initiate the circulation of drying air in the insulation-sealing assembly 101-102.

[0049] In [Fig. 1], the path of the air supplied to the insulation-sealing assembly 101-102 to be dried is shown by broad arrows, according to the legend shown in a frame at the bottom center of the figure. The dry and / or hot air 40a delivered by the supply inserts 10a into the assembly is represented by 90° curved white arrows without an internal pattern, on the left side of the figure. The humid air 40b extracted from the assembly by the supply inserts 10b is represented by 90° curved white arrows with a filling pattern having a maximum dot density, on the right side of the figure. Intermediate straight arrows, oriented horizontally from left to right and ordered along this direction, in white color and with a filling pattern having a respective increasing point density, represent the increasingly moisture-laden air circulating in the complex 101-102 between a supply insert 10a and an extraction insert 10b.

[0050] The drying process can be performed continuously, meaning that the supply and exhaust machines operate substantially continuously, seven days a week, twenty-four hours a day. If necessary, the machines can operate in supervised mode, i.e., under the control of an operator present on-site more or less permanently or operating remotely, and / or under automated control based on information provided by sensors and centralized at a control unit. This control is accompanied by updates, if necessary, of all the operating setpoint values ​​by which the dry air supply subsystem 20a and the humid air exhaust subsystem 20b are controlled.

[0051] In some embodiments, the control unit is remote, and regular monitoring can be performed remotely through the supervision ("monitoring") of the drying process. Preferably, the operating parameters of the machines can be adjusted locally or remotely based on various data collected. This adjustment can be controlled by a remote operator and / or result, at least in part, from the execution of an automatic control program running on a remote computer.

[0052] In all operating procedures, reading and comparing various hygrometric parameters of the supply air, the exhaust air, and the ambient air during the drying process allows validation of the completion of the drying operation based on one or more parameters reflecting the residual humidity level inside the insulation-sealing system. When this residual humidity level is below a predetermined threshold and a certain stability of this state is observed, the process is considered successfully completed, and the operation of the machines is stopped.

[0053] The control is, essentially, based to the first order on the humidity level in the humid air 40b which is extracted from the complex 101-102.

[0054] The use of vacuum gauges, preferably positioned at the air inlets to provide the most representative possible information on the spatial distribution of air pressure in the insulation-sealing assembly 101-102, also makes it possible to generate and maintain a negative pressure within the insulation / sealing assembly, in order to preserve its integrity. The negative pressure does not need to be significant, but its main purpose is to avoid, conversely, a state of positive air pressure anywhere within the assembly 101-102. Indeed, it is preferable not to This could create overpressure within the system, as pressurized air could infiltrate between the insulation layer 101 and the waterproofing membrane 102 of the insulation material and / or the anchoring zones to the underlying concrete slab 100, particularly at the waterproofing upstands typically installed around the perimeter, on the parapet walls of the structure. This could indeed cause irreparable detachment of the insulation layer 101 and / or the waterproofing membrane 102, which would ultimately lead to a risk of waterproofing failure due to tearing of the waterproofing layer 102, detachment of the rainwater drainage pipes, separation of the insulation 101 from the concrete slab 100, etc.

[0055] In some implementations, a drying report containing measurement curves for the various parameters during the operation can be produced at the end of the drying process. The publication of this report allows the success of the drying process to be validated for all interested parties, including insurers and project owners.

[0056] The installation of each of the air-handling inserts requires core drilling of the insulation-sealing assembly, and therefore piercing the sealing layer 102 directly above an air passage opening of the insert. A sealing treatment must be carried out, preferably by a roofer, i.e., a building sealing professional, whose work is covered by an insurance guarantee, for example, a ten-year warranty.

[0057] The ventilation inserts proposed here have been specifically designed to address waterproofing issues and allow for their permanent installation on the roof terrace, for possible future reuse. This allows them to be reused subsequently, either to carry out a new drying process in the event of a new incident, or to renew or supplement a drying process already carried out if necessary, or to perform waterproofing checks of the system by measuring hygrometric parameters within the system, or even to carry out tests using smoke or tracer gas to detect leaks. Furthermore, in order to withstand the test of time and weather conditions (rain, snow, frost, etc.), the inserts are, for example, made of stainless steel.

[0058] With reference to [Fig. 2], an air insulating insert 10 consists solely of a plate 15 from which extends, for example orthogonally, a tubular sleeve 11 (i.e., a hollow tube or cylinder) comprising an air passage duct 13, and which terminates at its free end 12 by a connecting fitting 12a. The plate 15, once laid flat on the waterproofing membrane 102 of the system to be dried as shown in [Fig. 3], allows the insert 10 to be sealed to said membrane 102, in accordance, for example, with the rules of DTU 43.1. By For example, fitting 12a is a male Cam-Lock™ connector, i.e., a Cam-Lock™ plug of type E, F (or F-AS), or A. Such a 12a connector has an annular groove and allows for the quick connection of a dry or humid air duct, for example, a flexible duct, which may be corrugated, for implementing the drying process. This duct connection is then made via a corresponding female connector, i.e., a Cam-Lock™ socket of type C, B (or B-AS), or D with locking levers. Of course, in some embodiments, the gender of the two connectors of the fitting may be reversed.The insert's 12a connection fitting also allows for the installation, after the drying process, of a female (e.g., a DC type Cam-Lock™ cap) or male (e.g., a DP type Cam-Lock™ cap) type sealing cap, respectively, depending on whether the 12a fitting is a male Cam-Lock™ plug (as shown) or a female Cam-Lock™ socket, respectively. These connection accessories are commercially available.

[0059] In embodiments as shown in [Fig. 2], the plate 15 can be produced as a single unit (i.e., in one piece) by casting, machining from a block of raw material, molding, or additive manufacturing (3D printing). Alternatively, the sleeve 11 can be manufactured separately from the plate 15 and permanently assembled to the plate 15, which has been previously drilled to form the air passage orifice 13a, for example, by welding at the orifice 13a. This embodiment avoids any risk of leakage at the plate 15 at the base of the sleeve 11, regardless of the assembly method used. This solution is a priori the least expensive for achieving this result.

[0060] In other embodiments, however, the sleeve 11 can initially be separated from the plate 15 and can be coupled to said plate, for example, by screwing, via a mutually provided thread and tapping on the two parts to be assembled, or by a quarter-turn push-fit mechanism, or by any other suitable means. The fact that the insert is thus made available in two parts to be assembled by the end user can reduce the volume of a batch of inserts, thereby facilitating the transport and storage of the batch. When the sleeve 11 and the plate 15 of the insert 10 are to be assembled by the end user, the sealing of their connection can be ensured, for example, with a sealing washer made of rubber, paper or leather which is compressed during assembly, and / or by placing a Teflon™ sealing strip on the thread, and / or by peripheral sealing by applying a sealing paste, etc.

[0061] As illustrated in [Fig. 2] and [Fig. 3], the upper face of the plate 15 (the face from which the sleeve 11 extends and which is opposite the lower face, or face, on which the insert 10 rests on the sealing liner 101 as illustrated in [Fig. 3]) may have at least a partially rough surface. A rough surface is a surface that is intentionally not perfectly smooth, for example, a textured surface (with the deliberate formation of unidirectional or bidirectional ridges), a striated surface, or an embossed surface. Such a surface has regular or irregular patterns such as undulations, striations, or motifs, in the form of "grains of rice," for example. It may be intentionally obtained by molding, punching, or embossing.Such a non-smooth surface condition gives the upper face of the plate 15 a better adhesion capacity which is favorable to the durable adhesion of a sealing coating for the insert 10, as will become clearer from the following exposition of a method of obtaining this sealing.

[0062] With reference first to [Fig. 4A], [Fig. 4B], and [Fig. 4C], the plate can be polygonal in shape, preferably square as shown, with rounded corners. A polygonal shape allows the plate to be manufactured by cutting a large sheet to form a plurality of plates without waste, thus avoiding material loss. The square or rectangular shape has the advantage that the cuts are straight, making them easier and faster to make. The square shape with rounded corners is preferred because, among all quadrilaterals of the same area, the square has the smallest perimeter (the square is the only solution to the iso-perimeter problem for quadrilaterals), which means that the square plate has the shortest cumulative length of peripheral edges, which must be sealed to prevent any water ingress at the level of the air inlet 10.In other words, for a given surface area of ​​the base plate 15, chosen in particular to provide sufficient stability before its watertight sealing and to reduce the risk of accidental detachment afterward, either during the drying process or afterwards (especially if the roof terrace includes pedestrian traffic), a square shape for the base plate minimizes the length of the perimeter to be sealed. Consequently, the square shape reduces the risk of water ingress in the event of an imperfection or degradation of the insert's watertight seal. Rounded corners reduce the risk of damage to the waterproofing membrane 102 of the insulation-waterproofing assembly 101-102 to be dried during the insert's installation. Sharp corners could indeed accidentally cause holes or cuts in this membrane.

[0063] A triangular shape of the plate 15 minimizes the number of strips of sealing material that need to be placed over the edges of the plate: this number is reduced to three for a triangle, instead of four for a quadrilateral (again, see further description of the insert sealing with reference to [Fig.3]). Alternatively, the plate can also be hexagonal, octagonal, etc., although these embodiments seem less advantageous.

[0064] In [Fig. 2], L and 1 denote, respectively, the length and width of the plate 15 if it is rectangular. In this case, the length L is greater than the width 1 (L > 1). If it is square, as in the example shown, these two dimensions are equal (L = 1). RI denotes the minimum distance between the outer surface of the sleeve 11 and a long side of the plate 15 if it is rectangular, and R2 denotes the minimum distance between the outer surface of the sleeve 11 and a short side. If the plate 15 is square, RI is, of course, equal to R2 (R1 = R2). Preferably, the lesser of the two distances RI and R2, that is, the smaller of the two, between the outer edge of the tubular sleeve 11 and the outer edge of the plate 15 is, at every point on the periphery of the plate, greater than 12 cm. It is preferably between 12 and 20 cm, for example, approximately 15 cm.In a preferred embodiment, the plate is square and its side dimension is approximately 28 cm (or 280 mm). In other words, L=l=280 mm.

[0065] The thickness of the plate and / or the thickness of the sleeve wall are greater than 1 mm, preferably between 1 mm and 5 mm, more preferably between 2 and 5 mm, for example equal to 3 mm. This value is a good compromise between the rigidity and strength of the insert 10, on the one hand, and material economy and weight of the insert, on the other.

[0066] With particular reference to [Fig. 4B], in which the left-hand portion is shown in longitudinal section along the section plane A-A' shown in [Fig. 4C], the extension height H of the sleeve 11 (including the connecting end 12a) above the plate 15 can be between 8 and 15 cm, preferably around 10 cm, for example 10.5 cm. To meet the specific requirements of certain applications, the height H can be reduced, for example, in the case of constraints on a thin plenum due to the assembly to be dried being located under a wooden floor or under slabs on pedestals.

[0067] The material from which the insert is made is ideally a non-corrosive material, such as stainless steel or galvanized steel, or any other metal intentionally treated against corrosion, for example by galvanizing or chromating. This is particularly important when good resistance to the salt spray test is required. It can also be a metal that is naturally non-corrosive under the conditions of use considered, such as zinc (Zn) or lead (Pb), or one that is only slightly oxidizable, such as aluminum (Al). Alternatively, it can be a synthetic material, such as a material selected from high-performance polymers, for example, polyphthalamides (PPA). The insert can also be made of metal chosen for its rigidity, and protected by a coating with good anti-corrosion properties such as a thermoplastic polymer coating from the polyamide family, for example polyamide 11 (marketed by Arkema™ under the brand Rilsan PA11™).

[0068] In some embodiments, the insert can be manufactured by additive manufacturing or three-dimensional (3D) printing of plastic or metal materials. For example, printing with plastic materials can be carried out by fused deposition modeling (FDM®) or FDM 3D printing, using a filament such as Acrylonitrile Styrene Acrylate (ASA), which is highly resistant to weathering, light (ultraviolet, or UV, radiation), and temperature variations, making it a good candidate for applications where the air intake insert is exposed to the elements. Powder bed fusion (PBF) printing is particularly well-suited for metallic materials such as titanium, stainless steels, and nickel-based alloys.3D printing now goes beyond rapid prototyping and enables the production of functional parts for end-use applications (known as "usable parts"). The insert is therefore a single-piece product, i.e., manufactured as a single unit. Those skilled in the field will appreciate that the 3D printing of insert 10 is well-suited to the specific characteristics of this recent technology, particularly since micro-structural control is not a critical requirement for this manufacturing process.

[0069] With reference to the diagram in [Fig.3], once the core drilling of the waterproofing coating 101 of the insulation-waterproofing complex 101-102 to be dried has been carried out to make a hole whose diameter corresponds to the inside diameter D int of the tubular sleeve 11 (see [Fig.4C]), the air insert 10 is put in place by placing it on its flat face (lower face), and this without any other intervention to be carried out on the layer of waterproofing coating 102 other than the aforementioned core drilling, with the air passage orifice 13a of the plate 15 correctly positioned at the hole (which will preferably be of the same diameter, approximately) formed through the waterproofing coating 102. The airtight sealing of the air insert 10 is then carried out by depositing strips of "SBS bitumen bilayer" material (see below).

[0070] This watertight seal provides improved sealing at the insert level compared to existing airtight inserts, thanks to the fact that the base plate is designed to rest flat directly on the complex 101-102 waterproofing membrane, positioned as described above directly over the core hole, and to be covered with a conventional waterproofing membrane that is easy to install and reliable over time. This operation is carried out by, and / or under the responsibility of, a professional waterproofing contractor, in compliance with applicable technical specifications. In France, of Such specifications are contained, for example, in the Unified Technical Document (DTU) number 43.1, entitled "Waterproofing of flat roofs and pitched roofs with load-bearing masonry elements in a plains climate", already identified above.

[0071] The value of the least distance (denoted RI or R2 in [Fig.4A]) between the outer wall of the tubular sleeve 11 and the peripheral edges of the plate 15, i.e., the distance between the outer wall of the sleeve and the points least far from the perimeter (i.e. the periphery) of the plate 15, is at least sufficient for the upper face of the plate 15 to be able to receive a sealing coating comprising for example strips 30 of "SBS bitumen bilayer" material, which is affixed straddling and overlapping the boundary between said plate 15 and said sealing coating 101 at said peripheral edges of the plate 15, as shown in [Fig.3]. The 30 strips of "SBS bitumen bilayer" material are laid with an overlap of the plate 15 for example over a minimum distance of approximately 12 cm (0.12 m), in the X,Y plane of the plate 15, from the edges of the plate towards the center of the plate and the tubular sleeve 11.In practice, the minimum distance of this overlap is defined, for example, by applicable technical specifications agreed upon to provide the necessary level of confidence in the quality of the watertight seal of the insert 10 to the sealing layer 101 of the assembly 101-102 to be dried. Optionally, a sealing upstand can be formed at the base of the tubular sleeve 11, towards its free end 12. Such a sealing upstand can extend to a minimum height of approximately 15 cm (0.15 m) along the direction of the vertical axis Z. This can be particularly advantageous when the base plate 15 and the sleeve 11 of the air inlet 10 are in two parts assembled by the user.The person skilled in the art will appreciate that the expression "straddling" used above means that the coating made up of the strips 30 is bonded partly to the plate 15 and partly to the sealing coating 101 of the insulation-sealing complex 101-102 to be dried.

[0072] With reference to the three views (a), (b), and (c) shown in [Fig. 7], the cam-lock™ connection systems allow for the quick, easy, and leak-proof connection of flexible hoses to each other, or the connection of flexible hoses to fittings or devices on subsystems 20a and 20b. The connection is made simply by inserting the quick-connect fitting (male part) into the cam coupler (female part). They are matched in diameter. Locking is achieved by folding down the two levers of the coupler, thus exerting constant pressure on a seal 73 (not visible in [Fig. 7] but which appears in the cross-sectional view on the left side of [Fig. 10]), to ensure a leak-proof connection.

[0073] With reference to the three views (a), (b) and (c) of [Fig.7], an air duct 31, for example a flexible corrugated duct, is then connected to The connecting tip is at the end of the cylindrical sleeve of the air insert. This figure simply shows a Cam-Lock 70 fitting that can be used for this purpose. In the example shown, the plug 71 (male connector) is fixed to the duct 31, and the socket 72 (female connector) would be fixed to the free end 12 of the sleeve (i.e., this socket would form the connecting tip 12a of the insert).

[0074] The arrows in view (a) on the left of [Fig. 7] illustrate the actuation of the locking levers of the sleeve 72, which allows the Cam-Lock™ fitting 70 to be locked to attach (or connect) the duct 31 to the tubular sleeve 11 of the air insert 10. The arrows in view (c) on the right of [Fig. 7] illustrate the actuation of the levers of the sleeve 72, which allows the Cam-Lock™ fitting 70 to be unlocked to separate the duct 31 from the air insert. View (b) in the center of [Fig. 7] shows the fitting 70 when locked.

[0075] Figure 5 shows, in front view, a first connection accessory 50 of the dewatering system 1, which is shown here horizontally. This connection accessory 50 (or fitting 50) is in the form of a straight tube segment comprising a hollow cylindrical body 51, terminated at each of its longitudinal ends by a connecting element 53 and 54, respectively, preferably a quick-connect element. In the example shown in the figure, such quick-connect elements 53 and 54 are, for example, Cam-Lock™ plugs (i.e., male connectors). The straight tube segment forming the wall of the cylindrical body 51 includes a socket 52, for example, a tapped hole in a well extending radially outwards from the body 51 as shown, for the insertion into said body of a moisture sensor 52a (shown in dashed lines in the front view of the figure).This sensor allows, for example, the temperature and / or humidity of the air circulating in said body 51 of the accessory 50. Preferably, the accessory 50 is made of stainless steel, but the constituent material variants which were considered above with regard to the aerodynamic insert 10 can also be considered for this accessory 50.

[0076] In embodiments, an accessory 50 as shown in [Fig. 5] can be directly coupled to a conjugate-type connection fitting at the supply turbine 21a of the supply subsystem 20a or at the exhaust turbine 21b of the exhaust subsystem 20b of the drying system 1 of [Fig. 1], optionally upstream of a dry air supply manifold 32a or a downstream humid air exhaust manifold 32b. In this way, the accessory 50 in which the sensor 52a is housed can benefit from thermal protection designed to protect the machines of the corresponding subsystem. This prevents distortion of the temperature measurement, in particular, when the ambient temperature can be very high (in summer) or very low (in winter). In winter, we also prevent condensation occurring locally at accessory 50 from interfering with the humidity measurement by sensor 52a.

[0077] Figure 6 shows, also in front view, another connecting accessory 60 of the drying system 1. This accessory 60 has the general shape of an elbow, namely a 90° elbow in the example shown in the figure. It comprises a hollow cylindrical body 61 made of two non-collinear straight tube sections extending along respective longitudinal directions oriented relative to each other at a 90° angle in this example (therefore, directions perpendicular to each other). Of course, the invention is not intended to be limited by the value of the elbow angle formed by the two straight tube sections of the fitting: fittings with two non-collinear straight tube sections oriented relative to each other at other angle values ​​are conceivable, for example, to form 45° or 135° elbows, or any other angle value.The two straight tube sections forming an elbow are joined to each other at one of their respective ends, at the elbow. Each is terminated at its other, free end by a connecting element 63 and 64, respectively, preferably a quick-connect element. In the example shown in the figure, the quick-connect elements 63 and 64 are, for example, a Cam-Lock™ plug (male connector) and a Cam-Lock™ socket (female connector), respectively. The wall of at least one of the straight tube sections of the cylindrical body 61 includes a socket 62, for example, a tapped hole extending radially into the body 61 as shown, for coupling a pressure sensor or vacuum gauge 62a to said body.This vacuum gauge measures the negative pressure of the air circulating in the angled cylindrical body 11 of the connecting accessory 60, in particular the humid air 40b circulating in the humid air extraction network 30b. Alternatively, or in addition to, a pressure gauge can be provided for measuring the air pressure, in particular the dry air 40a circulating in the dry air supply network 32a at the outlet of the dry air supply subsystem 20a. Preferably, the accessory 60 is made of stainless steel, but the material options considered above for the insert 10 can also be considered for this accessory 60.

[0078] In embodiments, an accessory 60 as shown in [Fig. 6] can be coupled by its female-type connection fitting 64 directly to the male-type connection fitting of the sleeve 11 of a supply insert 10a or an extraction insert 10b such as the insert 10 of [Fig. 2]. In this way, the vacuum measurement in the insulation-sealing assembly 101-102 is carried out with a vacuum gauge as close as possible to an access point of said assembly. Thus, any loss The possible aerodynamic load in the corresponding connection network has no influence on the accuracy of the depression measurement.

[0079] The embodiments of accessories 50 and 60 described above with reference to [Fig. 5] and [Fig. 6] are purely illustrative from a structural point of view. These accessories are characterized solely from a functional point of view by the nature of the sensor 52a or 62a they carry, which nature may have an impact on the arrangement of the accessory within the drying system 1, as indicated. Otherwise, that is, regarding the shape and arrangement, everything is interchangeable, namely the gender (male or female) of the connectors, the straight or angled shape, and the angle of the bend, if applicable. Connections with more than two non-collinear straight tube sections are also possible, for example, with three straight tube sections arranged in a "T", "U", etc., shape, according to the specific requirements of each application.A three-section T-connector allows, for example, the creation of a branch to another section of the air duct, or the formation of an extension to the duct, in which a measuring port can be placed without obstructing the airflow within the duct, and therefore without compromising the aerodynamic performance of the supply air network 30a or the exhaust air network 30b. A three-section U-connector can create a low point in the exhaust air network 30b, for example, to drain liquid water resulting from possible condensation of moisture in the air circulating within the network.Alternatively or in addition, a U-shaped fitting can create a high point for venting. When open, this vent can reduce air pressure in the air network, particularly in the supply network 30a, if needed. Furthermore, a single fitting can include multiple outlets, provided, for example, on separate sections of straight tubing or on the same section of straight tubing, which may even be a single outlet, as in the case of the straight fitting in [Fig. 5].

[0080] In embodiments, the system may include other accessories illustrated by the figures in [Fig.8] to [Fig.10], which may be used, where appropriate, with each other and in combination with the aerodynamic insert according to the invention.

[0081] With reference to [Fig. 8], an accessory of the tubular sleeve 11 of the air insert comprises an air guide element 80, forming a basic element of an air guide (and which is also referred to as air guide 80 in what follows), in the form of an elongated hollow tube (cylinder), with: • a cylindrical wall forming a body 81 of longitudinal extension (the longitudinal axis of this body being represented along the vertical direction Z vertically to the [Fig.8]), of circular section for example, with a longitudinal length greater than the longitudinal length of the air passage duct 13 in the tubular sleeve 11, and terminated by; • a proximal end 82, here the upper end of the body 81 in the representation of the figure, on one side; as well as by • a distal end 83, or lower end of the body 81 in the configuration shown in the figure, and which includes perforations 83a forming an air exsufflation strainer (when the insert is used as an insufflation insert) or air aspiration strainer (when the insert is used as an extraction insert), on the other side.

[0082] The basic air guide element 80 is generally in the form of a hollow tube or cylinder, the cross-section of which is the same shape as the cross-section of the air passage duct 13 (or internal duct) of the tubular sleeve 11 of an air insert 10, namely the circular shape in the example considered here. Furthermore, the air guide element 80 has external dimensions, namely an external diameter d ext in this case (see front view a) of [Fig.8]) which is slightly smaller than the internal diameter D int of the air passage duct 13 of the sleeve 11 of the insert 10 (see [Fig.4C]), so that it can be inserted into this internal duct 13 of the sleeve 11. In other words, the shape and dimensions of the cross-section of the element 80 correspond to the internal cross-section of the air passage duct 13 of the tubular sleeve 11. Thus, the air guide 80 then enters into sliding contact with the internal wall of the sleeve 11 of the insert 10.

[0083] The insertion of the air guide element 80 into the duct 1 of the tubular sleeve 11 of the insert 10 can be done by introducing the lower longitudinal end 83 of the element 80, which has perforations 83a, into the duct 13 through the free end 12 of the sleeve 11. This can be done, for example, once the insert 10 has been put in place and sealed by its plate 15 on the sealing coating 101 of the insulation-sealing assembly 101,102 to be dried, at the right of a core hole made in said coating 101.

[0084] As shown in the front view of [Fig. 10] (the left part of which is a longitudinal sectional front view), the lower longitudinal end 83 of the air guide base element 80, having perforations 83a, then protrudes substantially from the plane of the plate 15. In other words, it protrudes downwards beyond the air passage orifice 13a formed through the plate 15 of the air insert 10. In this way, the supply or intake strainer 83a protrudes substantially from the air passage orifice 13a of the plate 11 and penetrates the insulation material 101 of the insulation-sealing assembly 101,102.

[0085] The basic air guide element 80 and its end perforations 83a ensure, when such an element is used on the supply and / or exhaust side that dry air is blown into the complex or humid air is extracted from the complex, respectively, below the upper level of the insulation layer 101, in the volume of said insulation layer, or between said layer and the concrete slab 100, rather than between said insulation layer 101 and the waterproofing membrane 102. In other words, the air guide 80 allows for better control of the vertical position, i.e. along the vertical direction Z, of the level at which dry air is blown in, or at which humid air is extracted.

[0086] With reference to the partial cross-sectional view shown on the left side of [Fig. 10], one or more peripheral seals, for example O-rings or flat seals of suitable shape, namely circular with a square cross-section in the example, can be placed around or above the cylindrical air guide 80 in the sleeve 11, in order to prevent the circulation of supply or exhaust air between the inner wall of the sleeve and the outer wall of the air guide. This seal can be reinforced by means of the Cam-Lock™ fitting coupled to the air duct when this fitting is locked onto the sleeve's connection end.In this configuration the lower part of the fitting provides a stop plane for the upper end 82 of the air guide, the lower end 83 of which, fitted with perforations 83a, presses against the insulating material 101, this support providing an elastic reaction (due to the elastic compression coefficient of said material), which tends to make the air guide 80 rise upwards, by sliding in the duct 13 of the sleeve 11 of the insert 10. .

[0087] Ideally, the height of the air guide 80 is such that, when the guide is introduced into the sleeve of the installed insert by its terminal end 83 having perforations 83a and the latter rests by gravity on the insulation material 101 of the complex to be dried, its opposite proximal end 82 protrudes freely a few centimeters above the top level of the sleeve 11 of the insert 10. Thus, when the female connector 71 of the Cam-lock™ type of a flexible corrugated sleeve 31 is put in place on Cam-Lock male 71 forming the connecting end 12a at the upper end 12 of the tubular sleeve 11, it pushes the air guide 80 a few centimeters downwards, towards the center of the sealing material 101 into which it then sinks slightly.Once the fitting 70 is locked by lowering the levers 721 and 722 of the female connector 722 along the sheath 31, the elastic force exerted on the distal end of the air guide 80 tends to make it rise, which crushes the seal placed at the upper level of said guide, and ensures the sealing of the air guide 80 at this level by pressing against the inner edge of the female connector 72 of the fitting 70.

[0088] One or more air guide extensions such as extension 90 shown in [Fig. 9] can be butted together, i.e., joined end-to-end with each other and with an elementary air guide element such as element 80 shown in [Fig. 8], in order to adjust the length of the air guide to the thickness of the coating of airtightness as well as that of the underlying insulation material, in order to obtain more precisely the result indicated above. An extension 90 has an identical structure to that of the air guide base element 80 shown in [Fig. 8], but has a smaller longitudinal dimension (height along the vertical direction Z in the configuration shown). For example, the height He of the extension in [Fig. 9] can be between 5 and 10 cm, for an air guide base element 80 with a height Hg between 15 and 20 cm. It is a height extension element of the air guide base element 80. By coupling an air guide base element 80 with a height Hg and an extension 90 with a height He, a combined air guide is obtained with a height equal to Hg+He.

[0089] Those skilled in the art will appreciate that a set of extensions of different respective heights can be provided, allowing for a multitude of combinations of these extension elements to achieve any desired height. Of course, several extensions can be coupled together and to the basic air guide element 80.

[0090] To ensure this coupling, the terminal end 93 of the extension 90 may include, in embodiments, for example, lugs 93a of longitudinal extension of the tubular wall 91 which extend longitudinally in continuity with said wall 91. These lugs 93a, of which there are two in the example shown in [Fig.9], wrap slightly around the longitudinal axis 94 of the extension 90 (which axis is shown vertically in the figure), while remaining inscribed in a virtual extension (downwards, in the illustrated configuration) of the cylindrical envelope of the wall 91 of the extension 90.These lugs 93a are designed to snap into place, by means of a specific shape, with correspondingly numerous and shaped cutouts 82a provided in the cylindrical wall 81 of the base element 80, at the proximal end 82 of said element 80, which is the end shown at the top in the configuration of [Fig. 8]. The coupling is then achieved in a manner similar to a "bayonet" coupling. Advantageously, when the lugs 93a of the extension 90 are snapped into the corresponding cutouts 82a of the base element 80, said extension and said base element form an elongated air guide in the form of a tube having substantially continuous inner and outer walls. This method of connecting the extension 90 preserves the air guide function of the base element 80.Other forms of connection can be envisaged, for example by giving the lower end 93 of the extension 90 an external diameter smaller than the internal diameter of the upper end 82 of the base element 80, to allow one to be fitted into the other.

[0091] In addition, like a strainer, the perforations 83a provided at the lower end 83 of the base element 80 of the air guide allow for the filtering of particles of insulating material that might otherwise be drawn in with the extracted humid air through an extraction air insert 10a. The risk of such aspiration exists when said material tends, particularly due to aging or degradation caused by humidity, to break down into pieces of varying sizes. The diameter of the perforations 803a is adjusted to ensure the desired filtration while finding a compromise with the risk of clogging of the filter thus formed. In the event of clogging, it is sufficient to stop the operation of the system 1 and disconnect the air duct 71 from the insert 10 (see [Fig.10]), to remove the air guide 80 by extracting it from the sleeve 11 of the insert 10 from the top, and to clean the lower part 83 of the guide 80 in order to unblock the orifices 83a. .

[0092] The installation and operational use of the air-handling inserts of the drying system described above will now be briefly explained with reference to the step diagrams in [Fig. 11] and [Fig. 12]. These figures illustrate the operations carried out for the preparation of the drying procedure and during its execution, and those carried out at the end of said process, respectively.

[0093] The step diagram in [Fig. 11] illustrates the installation and use of an air-handling insert according to the invention.

[0094] In step (a), the position of a hole to be drilled in the waterproofing system 101-102 present on the building structure 100 is located using a drill pipe or core drill 110. The system comprises the insulation 101 covered on top by the single-layer or multi-layer forming lal02. In step (b), the core drilling is carried out using the core drill 110, which is rotated for this purpose. In step (c), the core drill 110 is removed. The hole 111 made in the waterproofing system, i.e., in the single-layer or multi-layer 102, exposes the insulation 101.

[0095] In step (d), the air-filled insert with its plate 15 is presented flat on the single-layer or multi-layer sealing coating 101, aligning the air passage orifice 13a of the plate (and therefore the air passage duct 30 of the tubular sleeve of the insert 10) with the core hole 111 made in said coating 101. If necessary, the operator who performs this operation can use the core drill in the manner of a centering pin (or centering device), to ensure the correct positioning of the air-filled insert 10, in line with the hole 111.

[0096] In step (e), the sealing coating 30 of the air insert 10 is placed straddling the edges of the plate 10 and the sealing coating 101 of the assembly to be dried, and it is sealed, for example, by heating with a gas torch 112. During this operation, the core drill 110 used as a centering device can be held in place to ensure the correct positioning of the insert 10. In step (f), the result is that the insert 10 is held firmly in position and sealed against the sealing coating 101 of the assembly to be dried. In step (g), the core drill 110, i.e., the centering pin, can be removed as it is no longer needed. The connection fitting 12a of the tubular sleeve of the insert is accessible.

[0097] In step (g), the air guide element or air guide 80 is then taken out, by its end including the perforations forming the strainer 83a, in the tubular sleeve 11 of the insert 10, from the top via the connection nozzle 12a of the insert.

[0098] In step (i), the air tube 80 is in place, with its distal end (at the bottom) having perforations 83a which is in the insulation 101 of the insulation-sealing complex to be dried, and with its proximal end (at the top) which protrudes very slightly upwards from the connecting end 12a of the tubular sleeve of the insert 10. An air line 31 equipped with a corresponding female Cam-Lock™ connector 72 is then placed on the connecting end 12a, which is a male Cam-Lock™ connector in the non-limiting example shown.

[0099] In step (j), the Cam-Lock™ fitting thus formed is locked by lowering the locking levers of the female connector 72, which connects the pipe 31 to the air insert 10. The female connector 72 presses from top to bottom against the proximal end of the air guide 80, which ensures an airtight seal between the pipe 81 and the air guide 80, optionally via a gasket (not shown).

[0100] The insert is then operational. In step (k) dry air 40a can be blown into the insulation 101 to be dried, or, depending on the use of the air-handling insert, humid air can be extracted from said insulation 101 in step (1).

[0101] The step diagram in [Fig. 12] illustrates the steps implemented after the end of the drying-dehumidification process, to neutralize the aerated insert so that it can be left on the roof terrace for possible later reuse.

[0102] At step (m), the Cam-Lock type fitting 70 is unlocked to disconnect the air line 31, and said line 31 is removed from the connecting end 12a of the insert 10.

[0103] In step (n), the air tube 80 is removed from the insert by pulling it upwards through the connecting nozzle 12a of the insert 10.

[0104] In step (o), a core 113 made of insulating material associated with the tubular sleeve 11 of the insert 10 is installed in place of the air guide 80. The core 113 is of a shape and dimensions adapted to fill the air passage duct 13 of said tubular sleeve 11, as well as the core hole 11 that had been made in the insulation 101 of the insulation-sealing assembly to be dried. In other words, the core 113 is longer than the air passage duct 13, and its length (considered according to the vertical direction) corresponds substantially to that of said conduit increased by the thickness of the insulation 101 in order to also fill the core hole 111.

[0105] Then, in step (p), the sealing cap 114 associated with the tubular sleeve 11 of the insert 10 is put in place on the connecting end 12a of said sleeve 11. In the example shown, the cap 114 is a Cam-lock™ DC type (female) cap.

[0106] At step (q), the cap 114 is locked by lowering its locking levers, which ensures the seal of the insert at the free end of the tubular sleeve 11. A tamper-evident seal, for example single-use, can be affixed to allow the indication, if necessary, of an unauthorized opening of the cap 114. The interested parties (project owner, company holding the drying site, insurer, in particular) may provide for contractual consequences in the event of such an unauthorized opening, such as the loss of the guarantee which the drying process may be associated with.

[0107] A person skilled in the art will appreciate that the implementation methods of the processes described above can be adapted to the specific characteristics of each application concerned, without departing from the teachings of the invention.

[0108] The curves in the diagrams of [Fig. 13], [Fig. 14], and [Fig. 15] illustrate the results of a drying procedure that can be carried out with the system according to embodiments of the invention described above. The curves in [Fig. 13] represent a record of values ​​measured continuously or almost continuously over a period of approximately two weeks (or approximately 14 days). In these diagrams, the horizontal axis represents the elapsed time, expressed in days, from the start of the procedure at a specific date d0. Those in [Fig. 14] and [Fig. 15] represent a record of values ​​over a period of approximately three and a half weeks (or approximately 24 days).

[0109] As already mentioned above, a drying-dehumidification procedure can take several weeks, depending on the extent of the water infiltration that has occurred, the volume of the complex to be treated (which is the product of the surface area of ​​the complex by the thickness of the layer(s) of waterproofing material that has absorbed water), the nature of the underlying material and which may determine whether or not drainage by gravity and / or capillarity, the geographical location and the time of year in which the procedure is carried out and which determine the temperature and humidity of the ambient air, the weather which may bring new water ingress in the event of precipitation during the procedure, etc.

[0110] Throughout the procedure, the values ​​measured by the various sensors are recorded continuously or almost continuously (i.e., at time intervals determined, relatively close together, for example at a frequency of between once every 15 minutes and times every hour, or even more frequently. [YES] The measurements represented by curves 131 and 132 in [Fig. 13] relate to relative humidity (RH), expressed as a percentage (%), in the supply air and the exhaust air, respectively. In other words, curve 131 shows the time t change in the relative humidity of the supply air over a period of approximately 14 days from the start of the drying procedure at time d0, and curve 132 shows the time t change in the relative humidity of the exhaust air during the same period.

[0112] In the example shown, between date d0 and date d0+12 days, the relative humidity of the supply air is less than 10%, being approximately 7.5%. From a date marked D3, which corresponds to date d0+12 days, until the end of the measurements, it rises to approximately 25%. This increase may coincide with a rainy episode or the local presence of fog, which causes an increase in the relative humidity of the ambient air that exceeds the system's capacity to dry the supply air. If other available weather information indicates that there were no such humid weather conditions on that date, the reading of curve 131 may indicate a potential failure of the supply air dehumidification device.

[0113] The main information with regard to the curves in [Fig. 13] is given by the measurement record represented by curve 132, concerning the relative humidity of the air extracted from the insulation-sealing system during drying. As can be seen and as shown by the dashed downward arrow 130, which follows the overall evolution of this curve between date d+3 days and date d+12 days, the relative humidity of the air extracted from the system decreases from approximately 65 to 70% to approximately 25 to 40% over this period. This decrease is essentially linear in terms of a daily average, but it is not continuous linear. On the contrary, drops in the relative humidity of the extracted air are observed at approximately one-time-a-day frequency.These decreases can be explained, for example, by the drop in temperature of the insulation-sealing system during each night, which reduces the efficiency of moisture extraction by the supply of dry air.

[0114] The comparison between the two curves 131 and 132 also provides information of interest to the operator and to the observers concerned. For example, the fact that the downward trend in relative humidity in the extracted air, represented by the downward arrow 130, stops at time D 3 could suggest that the drying process is not proceeding properly, without the possibility of realizing, by considering curve 131, that the humidity level is rising again The increase in humidity from date D3 onwards can be explained by a rational cause, for example, the occurrence of rain, as illustrated above. Indeed, if the humidity level of the supply air increases due to weather conditions, this provides an objective explanation for the increase in the humidity level of the exhaust air. Based on this information, the operator can decide to keep the system running, despite its relative inefficiency in relation to the intended objective. In fact, as soon as the weather conditions improve, curve 132 should begin to decline again, indicating a return to effectiveness of the drying procedure for the insulation and sealing system.

[0115] With reference to [Fig. 14], curves 141 and 142 represent the evolution over time t of the absolute humidity (AH), expressed in grams of water per cubic meter of air (g / m³), of the supply air and the exhaust air, respectively. On these curves, it is primarily the average difference between the absolute humidity of the exhaust air and that of the supply air that constitutes information of interest to the operator and the observers concerned. This difference is represented by a vertical dashed arrow 140, drawn between points on each of the two curves 141 and 142 approximately at time d0+10 days in the example shown.

[0116] More specifically, it is the evolution of this difference over time during the drying procedure that demonstrates the effectiveness of said procedure. Indeed, we see that at the beginning of the procedure, at time d0, and in the first few days that follow, the absolute humidity level of the air extracted from the system (curve 142) is significantly higher than that of the supply air (curve 141). In the example shown, the supply air has an absolute humidity level of approximately 5 g / m³, while the extracted air has a humidity level of approximately 15 g / m³. On the one hand, the difference between these two values ​​objectively demonstrates the extraction of moisture within the insulation-sealing system. Indeed, the extracted air is more humid than the supplied air, which objectively means that the air circulating in the insulation-sealing complex becomes saturated with moisture during its passage through said complex, i.e. that the complex dries out.On the other hand, the decrease in the difference 140 can be appreciated by observing that the gap between curves 141 and 142 narrows as the number of days in the operational period increases. Those skilled in the art will understand that at a date D4, occurring approximately at d0+22 days, curve 142, which until then was above curve 141, crosses the latter and then remains below it. In other words, the extracted air (curve 142) becomes less humid than the supplied air (curve 141). This means that, in reality, some moisture, albeit in small quantities, is undeniably delivered to the insulation-sealing system as a result of the procedure's implementation. In other words, continuing the procedure becomes counterproductive from date D4 onward: the effect obtained becomes the inverse of the initial result. the one that is being sought. Considering this information, the operator can make the decision to stop the drying procedure, appreciating that it has produced the desired result and that no further improvement, i.e. no further drying, can be expected if the procedure is continued beyond, but that on the contrary there is a risk of slightly increasing the humidity in the complex.

[0117] Curves 151 and 152 in [Fig. 15] are very similar to curves 141 and 142 in [Fig. 14]. They show the evolution of the mass of water, expressed as the number of grams of water per kilogram of air (g / kg), in the air supplied and in the air extracted from the insulation-sealing system, respectively. In [Fig. 15], the difference between curves 152 and 151 is represented by a vertical dashed arrow 150, similar to arrow 140 in [Fig. 14]. Those skilled in the art will appreciate that this difference decreases day by day between date d0 and date D5, which corresponds approximately to d0 + 22 days. It should be noted that the date of D5 in [Fig. 15] is approximately the same as date D4 in [Fig. 14], which is obviously consistent.

[0118] In other words, the information represented by the curves in [Fig. 15] can be used instead of that represented by the curves in [Fig. 14] to decide whether to continue or interrupt the drying-dehumidification procedure of the insulation-sealing system. Alternatively, the information represented by the curves in each of the two figures can be used for comparison to verify that the respective sensors used to produce the corresponding measurements are not defective, or that there is no other problem in the system that would generate an inconsistency between the information represented by the two pairs of curves in [Fig. 14] and [Fig. 15], respectively.

[0119] The present invention has been described and illustrated in the present detailed description and in the figures of the accompanying drawings, in possible embodiments. The present invention is not limited, however, to the embodiments presented. Other variations and embodiments can be deduced and implemented by those skilled in the art upon reading the present description and the accompanying drawings. Furthermore, although the invention has been described in the context of drying an insulation and waterproofing system for a roof terrace, those skilled in the art will appreciate that its teachings are also applicable to drying insulation materials found elsewhere in floors, subfloors, screeds, or even wall linings or drywall partitions.

[0120] In the claims, the term "include" or "comprising" does not exclude other elements or steps. A single processor or several other units may be used to implement the invention. The various features presented and / or claimed may be advantageously combined. Their presence in the description or in different dependent claims does not preclude this possibility. Reference symbols shall not be construed as limiting the scope of the invention.
