Description

The invention relates to a light and / or ventilation shaft, comprising a plurality of side walls and a bottom. Furthermore, the invention relates to a set for the production of a light and / or ventilation shaft and a corresponding manufacturing method.

Light wells, such as basement light wells are known in the art. Such light wells are usually prepared as finished parts and attached, for example, with flanges on a building exterior wall. After assembly, soil can be filled outside the shaft. Above the shaft, a grid or the like may be applied. Such a light shaft, for example, the DE 77 18 545 U be removed.

The publication WO 2004/074593 A1 describes a panel to form three-dimensional structures. According to 5 This document shows a bottom formed of two adjacent panels. The DE 73 181 28 U describes a light well with modules arranged one above the other, wherein a bottom is also provided.

It is still out DE 20 2005 000 442 U1 known to form the shaft of several modules, which are placed on each other in the vertical direction. This should be feasible different light shaft heights. Also the US 7,770,340 B2 describes a light well, which consists of several modules arranged one above the other. In one embodiment, the modules consist of mutually opposite side walls and a front wall, so that overall an approximately U-shaped layout of the modules is formed. The side walls are locked to the front wall. The superimposed side or front walls of the individual modules form side walls or a front wall of the entire light shaft.

Overall, the production of light wells is simplified by the stacked modules according to the prior art. However, the flexibility in manufacturing is still perceived as unsatisfactory.

It is an object of the present invention, a light and / or ventilation shaft, as well as a set or method for producing such a light and / or ventilation shaft to propose, the production costs, especially with varying requirements, should be further reduced.

This object is achieved by a light and / or ventilation shaft according to claim 1, a set according to claim 12, and a manufacturing method according to claim 14.

In this case, the light and / or ventilation shaft according to the invention comprises a plurality of side walls and a bottom and wherein the bottom has at least two preferably identical floor modules, which are interconnected via a connecting device.

A first core idea of the present invention is to form the bottom of a light and / or ventilation shaft in a modular manner. As a result, light shafts with a different width can be produced in a simple manner with comparatively few individual elements. As a result, the manufacturing costs are reduced overall, the flexibility of the light and / or ventilation shaft is increased.

The at least two floor modules can be identical, but also have different shapes or dimensions. In any case, the modular design allows, for example, by removing or adding another module, a comparatively simple adjustment can be made.

According to a second basic idea, the light shaft and / or ventilation shaft comprises at least one side wall, wherein the side wall comprises at least two, preferably identical, side modules which are connected to one another via a connecting device and are arranged side by side or one above the other in alignment. The modular construction of the floor, as described above, is combined with the modular design of the side wall according to the second aspect. In any case, a high flexibility in the production with consequent lower production costs can be achieved by the modular design of the side wall. The fact that the side modules are arranged side by side or one above the other, aligned in a simple manner, one (or possibly more) side wall (side walls) can be easily extended or shortened (for example, by removing one of the side modules or adding a further page module).

The term "module" (be it side module, floor module or cover module) should be understood in particular an element that forms essential portions of the side wall or the floor or a lid, z. B. at least 10%, preferably at least 30% of an entire side wall or an entire floor or an entire lid. In particular, the term "module" should not be understood to mean an element which merely serves for attachment or connection and does not have any ( substantial) proportion of a total area of the side wall or the floor or the lid has.

Preferably, at least three, more preferably at least five bottom and / or side modules are provided. As a result, the flexibility can be further increased.

Not all side modules must be arranged side by side, aligned. However, it is preferred if at least three or even at least five side modules are arranged side by side, aligned with each other. Basically, floor and / or side modules may have curved sections or be curved overall. Preferably, however, the bottom and / or side modules are designed as plane (board-shaped) elements or boards. The shaft or light shaft can be rectangular in a horizontal cross-section, or U-shaped (possibly with rounded corners).

Above the side walls, a cover element, in particular a grate, can be arranged. The cover element may comprise at least two cover modules. The cover modules can be designed in principle (in particular with regard to a connection and / or with respect to their number and / or shape and / or size) on the side and / or bottom modules.

The term "aligned" is to be understood in particular that the surfaces of the juxtaposed side modules define a common plane at least in a connection region or a respective connection region of, for example, at least 5% (or at least 10%) of an extension perpendicular to one Connection constant, located in a common plane. For example, a connection via a corner or a rounded connection area should be excluded.

The side modules are preferably identical, but may also be designed differently (in terms of shape and / or dimensioning).

In a preferred embodiment, the connecting device comprises a plug connection (preferably a tongue and groove connection) for connecting two side and / or bottom modules. With such a connection, the side and bottom modules can be particularly easily solved or assembled from each other, which reduces the manufacturing cost.

At least one side module and / or at least one bottom module is designed as a hollow chamber profile, wherein preferably within the at least one hollow chamber profile, a stiffening element, preferably a stiffening tube and / or stiffening profile, is provided. In such embodiments of the light and / or ventilation shaft, a high stability can be achieved with simple measures, which further reduces the manufacturing cost. At least one stiffening element can also be provided without the formation of a hollow chamber profile and / or on an outer and / or inner surface of the side or bottom wall and / or the side or floor module.

In a specific embodiment, an upper side wall edge may comprise a fastening device, in particular comprising a recess or a projection, preferably a slip-on profile, such that a cover element, in particular rust, of the light and / or ventilation shaft can be connected to the side wall edge. By such a design of the side wall edge basically a separate fastening element for a cover element, in particular rust, omitted. As a result, the light and / or ventilation shaft is further simplified in terms of design.

The side wall and / or the bottom can be sealed watertight, in particular by means of a support such as a film and / or a sealing tape. As a result, a reliable light and / or ventilation shaft is realized in a simple manner, despite the modular design.

At least two side and / or bottom modules can be of different sizes, in particular have a different width and / or length. For example, if side or bottom modules are designed as board-shaped, planar elements, a different width or depth of the light and / or ventilation shaft can be achieved by a different width of the individual modules in a simple manner.

In a specific embodiment, at least two side and / or floor modules (in cross section) may be rectangular.

Preferably, at least one cover element receiving strip is provided for at least one cover element, such as a grate, wherein the cover element receiving strip more preferably covers upper edges of at least two side modules. By such a cover element receiving strip, a fixing of the cover element or grate can be realized in a simple manner. If the cover element receiving strip additionally covers edges of at least two (or possibly all) side modules of a side wall, this will be achieved in a synergistic manner ensures that in addition the (entire) side wall is stabilized. In other words, two important functions can be accommodated with just one element. As a result, the manufacturing costs are lowered in a synergetic manner.

According to a more general idea, each edge of at least two modules may be included in a connection bar. The connection bar can be located, for example as a double C-profile, between the two side or floor modules. However, the connection strip can, for example, as a U-profile, record two edges of the at least two side and / or bottom modules, which are arranged one behind the other, for example - with respect to the side modules - an upper or lower edge.

Due to the connection strips in combination with the modular structure, a flexible adaptation can be done with little effort.

At least two (or at least three) soil modules can form at least 10% each, preferably 30% each of the soil. At least two (or at least three) side modules may accordingly form at least 10% each, preferably at least 30% each of a side wall. As a result, adaptation can take place in comparatively large steps, which increases the flexibility and thus reduces the production costs.

Preferably, a (vertically extending) corner recess is provided such that the light and / or ventilation shaft can be attached to a building corner, wherein the bottom has a plurality of parallel floor modules, wherein preferably a first plurality of floor modules a first length and a second plurality of floor modules having a second length that is different from the first length.

Due to the modular design, such corner ducts are particularly flexible and can be easily adapted to different geometries. In particular, when floor modules are provided with two different lengths, an adjustment of a corner slot can be done very easily. By arranging the light and / or ventilation shaft over the corner, it is particularly easy to realize a supply air and / or exhaust air duct. A heat pump can be installed comparatively easily. A light shaft to be installed can thus extend around the corner of a house wall. The depth and width of the light or ventilation shaft can be designed individually to cross-sectional shapes of each system used.

Preferably, a vertically oriented partition wall is provided or introduced into the light or ventilation shaft in order to divide the shaft into two sub-shafts.

By possibly removable or usable partition wall, the light and / or ventilation shaft can be particularly easily adapted to a particular preferred use. The partition wall allows separation of air-bearing compartments (for the supply and exhaust air). The partition should in particular be able to be mounted or removed so that mounting or fastening means are not destroyed (when removing the partition). The mounting means should preferably be used repeatedly (as distinct from integral or permanent attachment, such as by welding or gluing).

In an alternative embodiment, the partition may be firmly connected to the light shaft and / or ventilation shaft. This achieves a stable overall construction.

The above object is achieved independently by a set for the production of a light and / or ventilation shaft of the type described above, comprising a plurality of side modules and bottom modules, such that the width and / or depth of the light and / or or ventilation shaft can be varied using the modules. In particular, the width and / or depth of the light and / or ventilation shaft should be able to be changed by adding or removing one of the modules. Overall, a comparatively simple production of different light and / or ventilation shafts is made possible by such a set. This reduces the manufacturing costs.

Preferably, at least two modules are dimensioned differently, in particular of different widths. In general, however, two or more modules may be identical. Particularly preferably, the modules are present in at least three or even at least five different sizes. As a result, the manufacturing costs can be further reduced.

• – Hinzufügen von mindestens einem Seiten-Modul und/oder Boden-Modul zur Vergrößerung mindestens einer Seitenwand bzw. des Bodens oder
• – Entfernen von mindestens einem Seiten-Modul und/oder Boden-Modul zur Verkleinerung mindestens einer Seitenwand bzw. des Bodens.

The above object is achieved independently by a method for producing or resizing a light and / or ventilation shaft of the type described above, preferably with provision of a set of the type described above, with the following steps:

• Provision of several side modules to form a sidewall and at least two floor modules to form a floor,
• Adding at least one side module and / or bottom module for enlarging at least one side wall or floor or
• Removal of at least one side module and / or bottom module for reducing at least one side wall or the floor.

With regard to the advantages, reference is made to the above explanations regarding the light and / or ventilation shaft or the set.

In a preferred embodiment, the inner surface of the side walls and / or the bottom is at least partially provided with a waterproof coating, which covers at least one connection region between two side modules and / or floor modules. As a result, a high functionality of the shaft, in particular light and / or ventilation shaft can be ensured despite the flexible, modular design.

Overall, the production costs are reduced.

Preferably, the invention includes floor and / or side modules and / or connecting devices that have a bright, light-reflecting color. In particular, when using light white as a bright light-reflecting color for the bottom and / or side modules and / or the connecting devices in the shaft, in particular the light and / or ventilation shaft, incident light within the shaft is reflected such that z. B. a basement room is sufficiently lit. It is possible that the light color of the bottom and / or side modules and / or the connecting devices is applied to the respective modules in a coextrusion process.

Further embodiments emerge from the subclaims.

The invention will also be described in terms of further features and advantages based on embodiments, which are explained in more detail with reference to the drawings. Hereby show:

12 a view of the embodiment according to 9 in a view from above.

In the following description, the same reference numerals are used for the same and like parts.

1 shows a first embodiment of a light well in an oblique view. The light shaft comprises a floor 10 as well as a first sidewall 11 , second side wall 12 and third sidewall 13 , The first and second side wall 11 . 12 are arranged opposite each other. The third side wall 13 forms a connecting wall between the side walls 11 and 12 , Overall, the arrangement of the side walls 11 to 13 formed a U-shaped (horizontal) cross-section. One of the third side wall 13 opposite side 14 remains open or is defined in the assembled state, for example by a building wall (not visible in the figures).

The light shaft can have wall mounting elements 15 . 16 and 17 attached to a building wall (not visible). The fastening elements may for example comprise U-profiles, preferably made of aluminum or consist of such. In the present embodiment, the wall fastening elements comprise 15 . 16 and 17 L-profiles or consist of such. The wall attachment element 15 is on a vertical, in the assembled state of the building wall facing edge of the first side wall 11 appropriate. Accordingly, the fastener 16 on a vertical edge of the second side wall 12 appropriate. The wall attachment element 17 is at a facing in the assembled state of the building wall edge of the floor 10 appropriate. Overall, by the Wall fasteners 15 to 17 ensures a reliable hold on the building wall.

The floor 10 includes several (three) floor modules 18 , The side walls 11 to 13 comprise several (four each) stacked, horizontally oriented side modules 19 (Which are provided or designed for superposition).

At an upper edge 20 the side walls 11 to 13 is a grate holder 21 provided, which serves the support of a (not shown) grating. The rust intake 21 is U-shaped and has an outwardly and upwardly bent grate receiving edge 22 (please refer 2 ) on.

2 shows a view of the light shaft viewed from the front or from the building wall (in the mounted state of the light shaft). The wall fastening elements 15 to 17 have several (three each) holes 23 on to the wall fasteners 15 to 17 or attach the light shaft to a building wall.

3 shows a section along the line III-III in 2 , It can be seen that the floor modules 18 and the page modules 19 are formed as hollow chamber profiles. Within corresponding hollow chambers 24 are stiffening profiles 25 provided to increase the stability. Hint is in 3 to realize that the grate holder 21 with the topmost side modules 19 via a clip connection 26 connected is. Via corresponding clip connections 26 are also the individual page modules with a respective adjacent page module 19 or the ground 10 or its bottom modules 18 connected. The floor modules 18 are in turn with each other with corresponding clip connections 26 Mistake. Through such clip connections, the individual modules (possibly including the grate holder 21 ) are particularly easy to assemble and disassemble, which improves flexibility. Alternatively or in addition to the indicated stiffening profiles 25 can also be appropriate stiffening tubes in the hollow chambers 24 be introduced.

corners 27 (please refer 1 ) between the first side wall 11 and the third sidewall 13 or the second side wall 12 and the third sidewall 13 can be welded or otherwise connected. Alternative to the clip connections 26 can the individual floor modules or side modules 19 also be connected in another way (for example by an adhesive).

A length 28 (please refer 1 ) can be over the length of the floor modules 18 be adjusted. Corresponding to a depth 29 across a width of the floor modules 18 to be changed. In addition, the depth can be 29 about the number of floor modules 18 be varied. A height 30 can have a width of the side modules 19 and / or a number of the page modules 19 be varied. Overall, it can be seen that a large variety of different light shaft geometries can be achieved by floor or side modules of different lengths and / or widths and / or different numbers. Overall, the production costs are significantly reduced in the realization of various light wells.

In 4 is a second embodiment of a light well to see in an oblique view. The floor 10 with several (concrete three) floor modules 18 corresponds to (essentially) the first embodiment. Also the wall mounting over the wall mounting elements 15 to 17 corresponds (substantially) to the first embodiment. However, the second embodiment differs in particular by the formation of the side walls 11 to 13 , Namely, these comprise no horizontally oriented side modules, but vertically oriented side modules 31 (which are provided or designed for juxtaposition). The first side wall 11 and the second, opposite side wall 12 each include three side modules 31 , The third side wall 13 includes four page modules 31 , In the present embodiment, all vertically oriented side modules 31 identically formed, although the third side wall 13 longer or wider than the first and second side wall 11 . 12 is. It shows that with only one page module 31 several side wall sizes can be realized. In general, it is preferred that at least two side walls have a different width and / or differ by the number of possibly identical side modules.

The rust intake 21 consists of several (three) grate strips 32 that over an upper edge of the side walls 11 to 13 increased (specifically: postponed) are together and the Rostaufnahme 21 form. One grate holder each 32 covers an upper edge 35 from the side modules 31 one of each side walls 11 to 13 , As a result, the respective side wall or its side modules 31 stabilized. The rust receiving strip 32 thus serves two functions, namely on the one hand to rest a grate and on the other hand to stabilize the side modules 31 up to today. At a lower edge 36 the side walls 11 to 13 are the page modules 31 in a floor strip 33 added. This bottom bar 33 serves at the same time a connection to the ground 10 or its bottom modules 18 and a stabilizing compound at the bottom 36 the page modules 31 , At the corners 27 between the first side wall 11 and the third sidewall 13 as well as the second side wall 12 and the third sidewall 13 are corner profiles 34 arranged, each one (opposite the building in the mounted state) vertical edge of the side wall 11 and a corresponding edge of the sidewall 12 record as well as a vertical edge of the third side wall 13 , Through the corner profiles 34 the stability of the light shaft can be further improved.

The width or depth 29 The light well can be both the number and the width of the floor modules 18 be varied. In the second embodiment, moreover, a width of the side walls 11 . 12 and 13 about the number of vertically aligned second modules 31 as well as a width of the individual modules 31 be varied. For example, a different height of the light well may be provided by providing side modules 31 different length can be realized.

An essential idea of the invention (which is claimed independently) is that a light well is proposed, which is formed from a plurality of hollow chamber profiles.

Here, several U-profiles, for example, via a tongue and groove connection, stacked (interconnected). The U-profiles can consist of several (horizontally oriented) side modules 19 (according to the first embodiment according to 1 ), with the individual page modules 19 each one of the side walls 11 to 13 are assigned, can be welded together. By varying the length and width of the floor modules 18 as well as side modules 19 . 31 Light wells can be customized in width, depth and height.

The snap-in receptacle 21 can be designed as (extruded) attachment profile. On the bottom side, the light shaft can be closed with a bottom plate (which is not necessarily, at least with regard to the second embodiment according to 4 , must be designed modular).

The light shaft can in principle be waterproofed by cover tapes, films or other jobs, preferably watertight.

As stiffening elements within the hollow chambers 24 come alternatively rectangular profiles (for example made of steel), tubes, Rollformprofile and the like in question. By such stiffening elements of the light shaft can be stiffened depending on the size and installation depth against earth pressure or other loads.

Overall, the variability in width, depth and height (possibly also infinitely) depending on customer request light wells or ventilation shafts can be produced. For example, the light shafts can also be used for large windows. In principle, the light shafts can also be used as supply and exhaust air ducts for heat pumps and / or emergency exit. Due to the flexible wall connection also projections in the facade can be formed without problems.

The first and second embodiments relate to light wells, which are designed for mounting on a (substantially) flat portion of the building wall. Alternatively, corner light wells can be manufactured. 9 shows a third embodiment, which is designed as Ecklichtschacht. As with the previous two embodiments, the term "light well" is to be understood as an example of "well" only. For example, by providing a (not shown in figures) partition, a ventilation shaft can be realized. A combination of light shaft and ventilation shaft is possible.

The corner light shaft according to 9 differs essentially from the first and second embodiments of the light shaft in that the floor plan is not (substantially) rectangular, but L-shaped. The L shape is particularly good in 12 to recognize, which shows a view from above. The corner light shaft according to 9 includes a first sidewall 11 , a second side wall 12 , a third sidewall 13 as well as a fourth sidewall 37 , The first side wall 11 and the second side wall 12 lie opposite each other. Furthermore, there are the third side wall 13 and the fourth sidewall 37 across from. The first side wall 11 and fourth side wall 37 are opposite the second side wall 12 and the third sidewall 13 formed shortened, so that the L-shape is realized or a (vertically extending) Eckausnehmung 38 is trained. The corner recess 38 can then pick up a corner of a building (not shown in the figures).

As in 12 The first and fourth side walls are the same width, and the second and third side walls are the same width. However, it is also conceivable to form first and fourth side wall and / or second and third side wall of different widths. This can be done easily by varying the length of the floor modules 39 . 40 respectively. First floor modules 39 are opposite to second floor modules 40 (please refer 12 Shortened trained. An adaptation of the soil 10 of the light shaft according to 9 to 12 can also have a variation of the number of first floor modules 39 and / or second floor modules 40 respectively. In the specific embodiment shown are seven first floor modules 39 and three second floor modules 40 intended.

The side walls 11 . 12 . 13 and 37 each comprise several (actually five) side modules (which are aligned horizontally) 19 , corners 27 between the side walls 11 . 12 . 13 and 37 may be formed according to the first or second embodiment.

In general, the third embodiment may be formed like the first and second embodiments (with the described differences).

In particular, the 10 and 11 it can be seen that the third embodiment also has wall mounting elements 41 to 44 features. In contrast to the first and second embodiments, four wall fastening elements 41 to 44 provided in order to enable or facilitate the installation over corner.
