Definitions

  • the invention relates to a light shaft body and an arrangement with a light shaft body.
  • a light well body with the features of the preamble of claim 1 is from DE 44 23 831 A1 known.
  • Another light well body is off, for example CH 594 120 known.
  • the invention is based on the object of specifying a compact and stable light well body to which perimeter insulation can be quickly and easily attached without the formation of thermal bridges.
  • the invention is also based on the object of specifying an arrangement with such a light shaft body.
  • the object is achieved with regard to the light shaft body by the subject matter of claim 1 and with regard to the arrangement by the subject matter of claim 8.
  • the invention is based on the idea of specifying a light shaft body for a building opening, in particular a ventilation opening or a cellar window, with a one-piece wall.
  • the wall has a floor with at least one drainage connection, a rear wall and a flange for attachment to a building wall.
  • the bottom and the rear wall are connected to one another and form a transition area of the wall.
  • the base has a projection which projects beyond the transition area, the drainage connection being at a distance from the flange and at least partially, in particular completely, being formed in the projection.
  • the invention has the advantage that the perimeter insulation can be arranged between the flange and the drainage connection without the perimeter insulation being cut out, since the drainage connection is spaced from the flange and thus from the building wall in the installed state. This avoids thermal bridges that usually arise when installing the perimeter insulation. In addition, the installation of the light shaft body is simplified and accelerated.
  • the protrusion protruding over the transition area enables a particularly compact construction of the light shaft body and a corresponding saving in material during manufacture. Due to the projection, a distance between the drainage connection and the flange and thus the building wall is achieved without the floor area as a whole, that is to say over the entire width of the light shaft, being enlarged. Since the lead over the
  • the transition area between the rear wall and the floor, i.e. protrudes outwards, the floor is only widened locally in the area in which the drainage connection is arranged.
  • the floor to the side of the drainage connection can be made narrower and adapted to the wall thickness of the perimeter insulation.
  • the drainage connection is spaced from the flange with a minimum use of material, so that the full width of the perimeter insulation can also be worked onto the light shaft body in the area of the drainage connection.
  • the transition area delimits the floor in the horizontal direction.
  • the directional information "horizontal” as well as all other position information such as “above”, “below”, “front”, “rear” etc. relate to the installed state of the light well body.
  • the transition area can, for example, be a lower edge of the light shaft body at which the bottom and the rear wall intersect.
  • the transition area can also be designed as a continuous curve in which the wall leaves the plane of the floor. In general, it is important that the projection protrudes beyond the outer contour of the floor, which is defined by the transition area, so that the drainage connection is partially, in particular completely, arranged outside the insulation plane.
  • the insulation level is the level in which the perimeter insulation is located when installed.
  • the drainage connection is completely formed in the projection. This means that the drainage connection is arranged completely outside the transition area and the entire floor between the flange and the rear wall is available for perimeter insulation.
  • the advantage according to the invention of providing the largest possible closed floor area for the perimeter insulation is also achieved when the drainage connection is only partially formed in the projection, ie both in the projection and in the floor.
  • the floor area occupied by the drainage connection is reduced by the projection. It This means that more closed or built-in floor space is available for perimeter insulation.
  • the one-piece construction of the wall can be achieved, for example, in that the wall is manufactured as an injection-molded component.
  • the wall is preferably made of plastic.
  • the distance between the drainage connection and the flange in the area of the floor can be at least 10 cm, in particular at least 20 cm. This ensures that standard perimeter insulation can be installed between the drainage connection and the flange or the building wall without any problems.
  • the drainage connection opens at least partially into the rear wall. This contributes to the compact design of the light shaft body, because the rear wall forms part of the drainage connection.
  • the drainage connection forms a chimney-like bulge in the rear wall.
  • the chimney-like bulge leads to a stiffening of the light shaft body in the lower area. This is particularly advantageous because, due to the installation depth, the greatest soil and water loads occur in the lower area.
  • the floor preferably has a gradient to the drainage connection. This ensures that rainwater does not flow towards the building wall, but in the opposite direction, i.e. is directed towards the drainage connection. This prevents the adjacent facade plaster from becoming soaked and frozen.
  • the drainage connection particularly preferably forms the lowest point of the wall. This promotes the safe drainage of rainwater.
  • the wall has an upper stacking area in the installed state with stacking ribs for stacking light well bodies and a lower, smooth guide area in the installed state for guiding rainwater.
  • the wall thus fulfills a double function.
  • the wall enables several light shaft bodies to be stacked without them slipping.
  • the non-slip stacking of the light shaft bodies is important for transport and handling on the construction site and is becoming increasingly important. Since the stacking area makes up the upper part of the wall and the lower part of the wall is designed as a smooth guide area for guiding rainwater, rainwater is prevented from collecting in the lower area of the light shaft body.
  • the stacking area can have form-locking elements for securing stacked light shaft bodies and at least one spacer. This improves the security against slipping and the stackability without further accessories such as wooden blocks or wooden slats, since stacked light well bodies support one another through the spacers and secure one another through the form-fitting elements.
  • the flange has locking strips arranged in parallel for height adjustment. These allow the light shaft body to be adjusted without loosening screws or using tools, even if the excavation is partially filled.
  • a light well body according to an embodiment of the invention is shown, which is used as an underfloor element for building openings, in particular ventilation openings or basement windows.
  • the light shaft body is placed in the construction pit in front of a building opening in a manner known per se and connected to the building wall. Then the construction pit is filled, with a light shaft being formed through the light shaft body in front of the building opening.
  • the light shaft body has a wall 10 formed in one piece.
  • the wall 10 can be produced, for example, by an injection molding process and consists of plastic.
  • the one-piece construction has the advantage that a fluid-tight and stable light shaft body is created with relatively little material expenditure, which can be prefabricated and delivered in the factory as a prefabricated component.
  • the wall 10 of the light shaft body forms a downwardly tapering interior space 24 which, in the installed state, is delimited from the environment, ie from the ground, by the wall 10 and allows light to enter from above.
  • the wall 10 delimits the interior on all sides.
  • the wall 10 has a base 11 which forms the underside of the light shaft body.
  • the bottom 11 extends essentially in the horizontal direction.
  • a rear wall 13 is integrally connected to the bottom 11.
  • a window recess 26 of the light shaft body is arranged opposite the rear wall 13.
  • the window recess 26 surrounds the basement window in the installed state.
  • the rear wall 13 transitions laterally into the window reces
  • the wall 10 has side walls 25 which laterally delimit the interior space 24 and together with the floor 11 form the window recess 26. As in Fig. 1 shown, the transition from the rear wall 13 to the side walls 25 is continuous. Other geometries are possible.
  • the window recess 26 is surrounded by a flange 14 which is connected in one piece to the wall 10.
  • the flange 14 is used to connect the light shaft body to the building wall. Specifically, the flange 14 extends along the floor 11 and along the two side walls 25.
  • the flange also has openings in which fastening elements, such as screws or pins, can be arranged in order to fasten the light shaft body to a building wall after locking.
  • a light incidence opening 27 is formed, through which light can enter the light shaft body in the installed state.
  • the distance between the rear wall 13 and the window recess 26 increases with increasing height, so that the upper side of the light shaft body with the light incidence opening 27 is larger than the underside of the light shaft body with the base 11.
  • the bottom 11 and the rear wall 13 together form a transition area 15, which in the initial example according to FIG Fig. 1 is designed as a lower edge.
  • the lower edge forms a slightly curved or generally a continuously running outer contour of the floor 11.
  • Fig. 2 As can be seen, the rear wall 13 extends directly upwards from the lower edge 15 or the transition area 15. It is also possible for the transition region 15 to be designed as a continuous curve of the wall 10.
  • the bottom 11 has a projection 16.
  • the projection 16 is formed in one piece on the base 11 and protrudes outward over the transition area 15, specifically over the lower edge.
  • the projection 16 forms a nose which determines the profile on the underside of the light shaft body.
  • the protrusion of the projection 16 over the transition area 15 means that the projection 16 deviates from the continuously running outer contour of the base 11.
  • a drainage connection 12 is formed in the projection 16.
  • the drainage connection 12 is in accordance with the starting example Fig. 1 designed as an opening in the projection 16.
  • the drainage connection 12 is thus spaced from the flange 14 from the building wall. This creates a floor area free of built-in components, which is used as a system for perimeter insulation. There is no need to cut out or modify the perimeter insulation in the area of the drainage connection 12, without the underside of the light shaft body being significantly enlarged. The advantage of good thermal insulation without thermal bridges is therefore achieved with a minimum of material.
  • the distance between the drainage connection 12 and the flange 14 in the area of the base 11 is between 10 cm and 40 cm, in particular between 10 cm and 20 cm.
  • the drainage connection 12 is in the present case designed as a circular opening. Other geometries are possible.
  • the drainage connection 12 opens into the rear wall 13 and thereby forms a chimney-like bulge 17 in the rear wall 13.
  • the chimney-like bulge 17 is well in the Figures 2 and 3 to recognize.
  • the bulge 17 projects outward beyond the rear wall 13. This not only achieves a good drainage of rainwater through the drainage connection 17, but also a stiffening of the rear wall in 13 in the area close to the ground, i.e. where the earth and water loads are particularly high.
  • the projection 16 is essentially aligned with the bottom surface of the bottom 11, that is to say lies essentially in the same plane as the bottom 11.
  • the chimney-like bulge 17 rests on the projection 16 and extends upwards from the projection 16.
  • the chimney-like bulge 17 forms the closure of the rear wall 13 to the outside and at the same time guides rainwater to the drainage connection 12.
  • the profiling of the rear wall 13 by the chimney-like bulge 17 has a further advantage and promotes the stackability of the light shaft body.
  • the outer contour and the inner contour of the chimney-like bulge 17 are appropriately designed so that when stacking several light shaft bodies, the chimney-like bulges 17 interlock and thus secure the stack.
  • the drainage connection 12 is arranged in the middle. It is also possible to arrange the drainage connection 12 laterally offset, that is to say off-center. Instead of the chimney-like bulge 17, a different geometry can be selected for the drainage connection 12.
  • the floor 11 is inclined towards the drainage connection 12 in order to guide the rainwater away from the building wall.
  • the drainage connection 12 is located at the lowest point of the wall 10.
  • stacking ribs 19a, 19b are formed in the wall 10.
  • the stacking ribs 19a, 19b extend essentially parallel to one another or parallel to the base 11.
  • the stacking ribs 19a, 19b are designed so that the outer contour of the respective stacking rib 19a, 19b fits into the inner contour of a corresponding stacking rib 19a, 19b when the light well bodies are stacked.
  • the stacking ribs 19a, 19b at the same time increase the stability of the wall 10 and therefore act as reinforcing ribs.
  • the upper, first stacking rib 19a is only formed in the area of the rear wall 13.
  • the lower, second stacking rib 19b is formed both in the area of the rear wall 13 and in the area of the two side walls 25. Therefore, the second stacking rib 19b causes a stiffening both in the area of the rear wall 13 and in the area of the side walls 25. Overall, the stacking ribs 19a, 19b significantly stabilize the light well body and protect it against buckling or denting.
  • the stacking ribs 19a, 19b are formed in the upper region of the wall 10. Specifically, the stacking ribs 19a, 19b are arranged in the upper third of the light shaft body and form a stacking area 18. It is possible to provide more than two stacking ribs 19a, 19b.
  • the stacking ribs 19a, 19b have vertical reinforcements 27 which increase the rigidity of the light shaft body or the wall 10.
  • the outer contour of the stacking ribs 19a, 19b protrudes beyond the vertical reinforcements 27, so that the stackability of the light shaft bodies is maintained.
  • the wall 10 forms a lower, smooth guide area 20 for draining off rainwater.
  • the guide area 20 runs out towards the drainage connection 12 in order to concentrate the rainwater there.
  • the stacking area 18 has two spacers 22a, 22b which are arranged below the second stacking rib 19b.
  • the spacers 22a, 22b are each a peg that protrudes inward, ie into the interior of the light shaft body.
  • the spacers 22a, 22b are used to securely arrange the stacked light shaft bodies on top of one another so that they support one another. Accessories such as wooden blocks and wooden slats or the like are therefore not required.
  • the arrangement of the stacking ribs 19a, 19b is chosen so that a pressure rail can be used for the pressurized water-tight assembly without interruption. With very little use of material, only two stacking ribs 19a, 19b are formed on each, which nevertheless offer a wide support surface and protect the light shaft flange from deformation.
  • a product identification area is provided in the upper area of the light shaft body. This area is used to recognize the article number, the date of manufacture, the manufacturer and recycling logo from above, even when filled. This makes the procurement of accessories easier.
  • Fig. 5 it is shown that the flange 14 has locking strips 23a, 23b arranged in parallel for the height adjustability of the light shaft body.
  • the locking strips 23a, 23b are shown in detail in FIG DE 10 2013 109 817 A1 described and claimed, which goes back to the applicant.
  • Locking strips 23a, 23b each cooperate with a locking block (not shown) for connecting the light shaft body to a wall of a building.
  • the locking strips 23a, 23b allow the height of the entire light shaft body to be adjusted in steps of 5-10 mm without having to loosen screws. In addition, a subsequent height adjustment is possible, which not only affects the pressing of the light shaft flange with the wall at the Light shaft fixation sets.
  • the load is transferred by a non-positive connection between the locking block (not shown), the light shaft flange 14 and the wall.
  • the locking block connected to the wall securely engages the locking tabs of the locking strips 23a, 23b, which prevents the light shaft from lowering under load. Fastening screws or nuts that are tightened too little have no effect on the secure hold of the light shaft.
  • the connection between the locking block and the light shaft flange 14 can be released by hand without the use of a tool.
  • the light well body can be pulled up when it is filled.
  • the load is only transferred via the two upper attachment points, ie via the locking blocks.
  • the locking strips can extend over the entire flange height.
  • Fig. 6 shows several light shaft bodies stacked one inside the other.
  • the light shaft bodies are arranged one above the other and the spacers 22a and 22b engage in the form-fit elements 21. It is easy to see how all elements or the profiling interlock to save space and how there is only a small distance between the individual light shaft bodies. This facilitates the transport and storage of the light well body.
  • securing elements such. B. pins, bolts and / or cable ties, for transport or for temporary storage on a construction site in the locking strips 23a and / or 23b and / or the openings in the flange.
  • a cover 28 is arranged in the area of the window recess 26.
  • the cover 28 can be inserted between a building wall and the rear of the light shaft.
  • the outer edges of the cover 28 are delimited by the flange 14 and the wall 10, so that the cover 28 is held in a defined manner between the rear of the light well and the building wall.
  • the arrangement of the cover 28 advantageously eliminates the need to apply a plaster in the area of the light shaft.
  • the cover 28 takes on the function of the plaster or protects the building opening from contamination while the building is being plastered.
  • the cover 28 is preferably made of Made of plastic, but other materials, such as. B. metal or ceramic can be used.
