Description

BE2025 / 5034 2 To this end, the invention provides for a box structure characterized by the fact that the box structure contains at least one reinforcing element, which reinforcing element has a base intended to connect to the underside of the box structure, where the reinforcing element further contains a first connecting wing connected to the base, which first connecting wing extends upwards from the base, which reinforcing element further has a roof element intended to connect to the top side of the box structure, where the reinforcing element further contains a second connecting wing connected to the roof element, which second connecting wing extends downwards from the roof element, where the first and second connecting wings are mutually connectable to hold the base at a predetermined distance from the roof element.10 By providing a reinforcing element that extends between the bottom and top of the cabinet assembly, the overall rigidity of the cabinet is increased.This avoids the risk of deformation of the enclosure, which could damage or cause a roller shutter or screen fitted inside the enclosure to malfunction. When a ventilation unit is fitted inside the enclosure, ventilation openings at the end of the enclosure, and possibly also partly through the enclosure, can be calibrated during manufacturing and remain correct even after installation. This contrasts with existing systems, namely that most mounting systems on the market must be manually adjusted on site, which is time-consuming and prone to errors, whereas the reinforcing element of the invention ensures that the height of the enclosures, the air supply openings, and the air exhaust opening are not significantly affected by the manufacturing, storage, transport, and installation of the enclosure. Therefore, no manual adjustment of the mounting systems needs to be performed, and the airflows can already be calibrated during manufacturing. be measured and adjusted without the need for further adjustment on-site after installation, because the cabinet could be deformed.However, provision is also made to ensure that the window or door can be structurally secured better in the opening, namely that the window or door is typically connected to the underside of the frame. The top of the frame is typically connected to the structure of the building. Through the reinforcement element, the indirect connection between the window and the structure of the building is thus strengthened. Preferably, the roof element contains a roof plate with at least one first opening and, at a distance from the roof plate, a guide plate with at least one second opening positioned relative to at least one opening such that an axis line passes through both of the latter openings and extends at an angle into the surface-mounted cabinet. Furthermore, preferably, the axis line intersects the front of the surface-mounted cabinet. Providing a reinforcement element in a surface-mounted cabinet presents practical problems, namely that it is difficult to place a fastening element such as a screw, a nail, or a plug that connects the cabinets to the structure of the building.The main reason is that there is too little space in the cabinet to operate a 2025 / 5034 BE2025 / 5034 3 drill or hammer in a simple manner. The invention provides a solution that is surprisingly simple, namely by providing the roof element with two openings, spaced apart, such that an axis line through the openings is at an angle and preferably intersects the front of the mounting cabinet. The two openings form, on the one hand, a drilling jig, namely that a drill can be stably guided through the two openings, and on the other hand, a sturdy holder for a fastener such as a screw, a nail, or a plug. Because the axis line intersects the front of the mounting cabinet through the two openings, and the front is removable to provide access to the mounting cabinet, the fastener can be inserted extremely easily via the open front of the mounting cabinet. Not only during assembly, but this is also relevant during the disassembly of the reinforcement element, namely that the 10 reinforcement element can be completely disassembled from the open front.Preferably, the roof panels and the guide plate are folded from a single sheet, with a fold line separating the roof panel from the guide plate. Furthermore, preferably, the roof panel and the guide plate show an angle of at least 90 degrees in cross-section at the location of the fold line, preferably at least 100 degrees, or preferably at least 110 degrees, and of a maximum of 160 degrees, preferably a maximum of 150 degrees, or preferably a maximum of 140 degrees. By folding a sheet, the roof element of the reinforcement can be formed in an extremely simple and inexpensive manner. Preferably, the underside of the superstructure has grooves in which the base has dimensions to fit into the groove. By providing a groove into which the base fits, correctly positioning the base in the superstructure is extremely simple. Preferably, the groove on the front side of the superstructure cabinet has an inward edge where the base hooks at the back.Furthermore, preferably, the base has an upward edge on the rear side of the surface-mounted cabinet such that a fixing pin can be inserted at an angle into the surface-mounted cabinet to connect the base to the underside of the surface-mounted cabinet, where the angle is chosen such that the axis of the fixing pin intersects the front of the surface-mounted cabinet. By providing a hook connection on the front and a fixing pin, such as a screw, on the rear, securing the base in the surface-mounted cabinet with the open front becomes extremely simple. Namely, from the open front of the surface-mounted cabinet, the base can be clamped with its front behind the inward edge, then placed in the groove and correctly positioned, to subsequently be secured with the fixing pin from the open front. This is relevant not only during assembly but also during the disassembly of the reinforcement element, namely that the reinforcement element can be completely disassembled from the open front.Preferably, the first and second connecting wings are mutually connectable at at least two different mutual positions. Preferably, the first and second 2025 / 5034 BE2025 / 5034 4 connecting wings are mutually connectable at at least two different mutually horizontal positions. The two mutual positions allow the use of the same elements in different situations. The two mutually horizontal positions allow the upper connecting wing to be positioned deeper or shallower within the same box. This allows the position of the upper fixing pin to be adjusted to the location of the building structure relative to the box. This increases flexibility when installing the box. Preferably, the first and second connecting wings have corresponding openings and are interconnectable via fasteners such as bolts. The bolts can be easily tightened and loosened via the front of the mounting box. Preferably, at least one of the first and second connecting wings has slot-shaped openings.The slot-shaped openings, especially in combination with fasteners such as bolts, allow for stepless repositioning of the upper connecting wing relative to the lower connecting wing. The lower connecting wing, which is connected to the base, which is typically fixed in the slot on the underside15, is fixed. The position of the upper connecting wing, which is connected to the roof element, can then be adjusted depending on the desired location of the fastening elements that connect the roof element to the top side and to the structure of the building. Preferably, the first and second connecting wings are almost sheet-shaped20 and extend mainly transversely to the longitudinal direction of the box structure. Furthermore, preferably, the first connecting wing and the base are folded from a single sheet, where a fold line separates the first connecting wing from the base and where the second connecting wing and the roof element are folded from a single sheet, where a fold line separates the second connecting wing from the roof element.Simulations and tests have shown that this results in an extremely sturdy and easy-to-manufacture reinforcement element. Preferably, the casing has a central space within which a roller shutter or screen can be placed, and where the first connecting sash and the second connecting sash are located outside the central space within the casing. This allows multiple reinforcement elements to be provided even when a roller shutter or screen extends into the casing, namely that these do not prevent the roller shutter or screen from being located inside the casing. The invention will now be described in more detail using several execution examples shown in the drawings.The drawing shows: 35 2025 / 5034 BE2025 / 5034 5 Figure 1 a screen illustration of a preferred design of the invention; Figure 2 a detailed design of an upper part of the reinforcement element according to the invention; Figure 3 a detailed design of a lower part of the reinforcement element according to the invention; and Figure 4 a cross-section of a practical situation in which a cabinet with a reinforcement element according to a preferred design is provided in a building opening. In the drawing, the same reference number 10 is assigned to the same or analogous element. Figure 1 shows a cabinet assembly 1 in perspective, cut through at the location of a reinforcement element 7. The cabinet assembly is composed of a top side 2, front side 3, back side 4 and bottom side 5. The sides are typically formed by profiles, with the front side typically being a separate profile to facilitate opening of the front. Top side 2 and rear side 4 can be formed from a single profile, however this is not essential.The bottom side 5 is typically not completely closed so that a roller shutter or screen can extend outwards through the bottom side 5 of the shielding box. When a ventilation unit is provided in the surface-mounted box 1, an airflow can be facilitated via the bottom side 5 of the surface-mounted box 1. The bottom side 5 is typically provided to be connected to the top side 20 of a window or door. The top side 2 is typically provided to be connected to the inner wall. A roller shutter 6 can be provided in the surface-mounted box 1. Alternatively, a screen or a ventilation unit can be provided in the surface-mounted box 1. In Figure 1, a reinforcement element 7 is shown. The reinforcement element 7 extends between the bottom 5 and the top 2 of the superstructure box 1 to connect these sides to each other. The reinforcement element 7 is further provided in a removable manner in the superstructure box 1 so that the reinforcement in element 7 can be easily placed in the superstructure box 1 as well as removed from the superstructure box 1. The reinforcement element 7 is constructed from a lower stone and an upper part. The lower part has a base 8 and a first connecting wing 9.The upper part has a roof element 10 and a second connecting wing 11. When the first connecting wing 9 is connected to the second connecting wing 11, as will be explained further below, the reinforcement element 7 forms a solid element with which the bottom 5 and the top 2 of the mounting box 1 can be connected to each other. By separating the connecting wings 9 and 11 from each other, the reinforcement element can be easily disassembled and reassembled 35 in the mounting box 1. By providing the connecting wings 9 and 11 as separate parts that can be connected to each other with 2025 / 5034 BE2025 / 5034 6, the relative position of the first connecting wing 9 in relation to the second connecting wing 11 is also adaptable to the specific situation of the mounting box 1 and its position on the window and in the wall. In this way, the connecting element 7 can multiple different situations can be used with the same components. The upper part of the reinforcement element7 preferably also has a guide plate14 in addition to the roof plate12 by5.In addition, a first opening 13 is provided in the roof plate, while a second opening 15 is provided in the guide plate 14. The openings are shown in Figure 2. The guide plate 14 is positioned at least partially at a distance from the roof plate 12. Preferably, the guide plate 14 is positioned at an angle relative to the roof plate 12. As a result, the first opening 13 and the second opening 14 are also at a distance from each other, and thus 10 an axis line can be drawn through the center of these two openings 12 and 14. The positioning of the openings 12 and 14 is chosen such that the axis line intersects the front side 3. The consequence is that a drilling can be easily carried out and that a screw, nail, or pin can be easily tightened or loosened in the mounting box 1. The openings function as both drilling templates and mounting holes for securing the reinforcement element 715. The lower part of the reinforcement element7 has a base8 which preferably has a hook part at its front side that is adapted to grip an inward edge18 of the underside5. In this way, the base8 can be hooked behind the inward edge18.Furthermore, preferably the base8 has an upward edge19 on its rear side, shown in figure 3, in which a mounting opening20 is provided. Because the mounting opening20 is provided in an upward edge19 located on the rear side of the base8, drilling can be easily carried out and a screw, nail, or pin can be easily tightened or loosened in the mounting box1 via an open front side3. This makes the lower part of the reinforcement element7 easy to place in and remove from the mounting box1. To facilitate the placement of the base8, the underside5 is preferably provided with a groove25 17 with dimensions into which the base8 fits, as shown in figure 1. The base8 can be secured with screws extending straight down from a middle part of the base8, and / or can be secured with a screw or pin extending at an angle and which The fastening opening is provided, as shown in Figure 1. The first connecting wing 9 and the second connecting wing 11 have 30 corresponding openings to allow easy mutual connection.In Figure 1, the first connecting wing 9 has multiple openings 22 and the second connecting wing 11 has slot-shaped openings. The first and second connecting wings can be connected to each other via bolts 23 and nuts that are passed through the openings 22 and slots 24. The slots allow the first connecting wing 9 to be secured at different locations relative to the second connecting wing 35 11. The professional understands that not all openings 22 2025 / 5034 BE2025 / 5034 7 need to be used, and that the openings 22 can be chosen that best correspond to the desired relative position of the first and second connecting wings 9,11. Figure 2 shows the upper part of the reinforcement element 7. This part comprises the second connecting wing 11, the roof plate 12, and the guide plate 14. Preferably, this part is formed from a single piece of sheet material that is folded in such a way that fold lines separate the second connecting wing 11 from the roof plate 12 and from the guide plate 14. Thus, fold line 26 is indicated in Figure 2, which separates the second connecting wing 11 and the roof plate 12.Also shown is the curve or fold line16 that separates the roof plate12 from the guide plate14. The first opening13 is provided in the roof plate 12 and the second opening15 is provided in the guide plate14. The connecting slots14 are provided in the second connecting wing11. Figure 3 shows a lower part of the reinforcement element 7. This part comprises the first connecting wing 9 and the base 8. Preferably, this part is formed from a single piece of sheet material that is folded in such a way that fold lines separate the first connecting wing 9 and the base 8 from each other. Thus, in Figure 3, fold line 25 is indicated which separates the base 8 from the first connecting wing 9. The base 8 is provided with the upward edge 19 in which the fastening opening 20 is provided to attach the base to the underside 5. The first connecting wing 9 contains multiple openings 22. The professional understands that the first connecting wing 9 can also have slot-shaped openings and / or that the second connecting wing 11 can also have openings. Figure 4 shows a practical situation in which a surface-mounted cabinet 1 is built into an opening of a building.The building has an outer wall29 and an inner wall28, between which there is typically a cavity, which may or may not be filled with insulation material. A window30 is shown in the opening of the building. The surface-mounted cabinet1 is positioned on, that is to say above, the window30. The bottom of the surface-mounted cabinet1 is connected to the top of the window30. Figure 4 shows how the opening at the bottom of the surface-mounted cabinet1 is located on the outside of the window30 so that the screen or roller shutter on the outside of the window can be moved up and down. When a ventilation unit is provided in the surface-mounted cabinet1, air can be drawn in and blown out at the location of the opening on the outside of the window3030. In the aforementioned case, openings can then also be provided on or in the front3 to draw air from the building and blow it into the building. The cabinet assembly in Figure 4 has essentially the same elements as those in Figure 2. In Figure 4, it is additionally shown how roof plate 12 and guide plate 14 make it possible to connect the reinforcement element 7 with the inner wall 28.Figure 4 shows the bolt of 2025 / 5034 BE2025 / 5034 8 that has been passed through openings 13 and 15 into the inner wall 28 and illustrates how the reinforcement element 7 and thus also the top 2 of the wall-mounted cabinet 1 is connected to the inner wall. The bottom 5 of the wall-mounted cabinet 1 is connected to the window 30. Because the invention does not specifically concern this connection, the method of connection is not further specified 5. A wall-mounted cabinet 1 can have several reinforcement elements 7 provided across the width of the wall-mounted cabinet 1. For example, a reinforcement element 7 can be provided approximately every 80 cm, every 100 cm, or every 120 cm. A reinforcement element 7 can also be provided near an end of the wall-mounted cabinet 1 so that the end 10 of the cabinet must be constructed less strongly. Figure 4 also shows why the reinforcement element 7 is particularly interesting for the application of surface-mounted cabinet 1. A surface-mounted cabinet 1 is provided above the window 30; to make this possible, there is a gap between the inner wall 28 and the window, between which the surface-mounted cabinet 1 is placed.This distance ensures that the window30 cannot be attached directly to the 15 inner wall28. The reinforcement elements7 ensure an indirect connection so that the stability of both the mounting cabinet1 and the window30 is improved.
