Definitions

  • the invention relates to a wooden floor construction and a wooden building.
  • the construction of multi-storey buildings in wood construction is also limited by the characteristics of the wood.
  • the longitudinal and / or cross members rest on a lower support, while the upper support in turn rests on the longitudinal and / or cross members.
  • the direction of the fibers of the longitudinal and / or cross beams is in the plane of the floor, ie at right angles to the supports.
  • wood has the property of being very stable to the forces acting in the longitudinal direction of the grain of the wood, but very weakly perpendicular to the grain. If a support now lies on a cross and / or longitudinal beam, the entire force of the upper support is first transferred to the cross and / or longitudinal beam and only from there to the lower support. So that is through the Upper support load to be borne by the transverse stability of the side and / or cross members.
  • Multi-storey buildings multiply the weight of a prop on the cross and / or longitudinal beams. Therefore, too many floors in timber construction are not possible today.
  • DE2108524 discloses a support structure made of steel, reinforced concrete or plastic.
  • the floor slab construction has a first lower wooden support for supporting the floor slab, a first upper wooden support for supporting a further floor slab and a first wooden support head for introducing the forces of the floor slab into the first lower wooden support.
  • the first column head rests on the first lower wooden column, and the first upper wooden column rests directly on the first lower wooden column.
  • the first support head (6) made of wood has a first main fiber direction (14) and a second main fiber direction (15) which differs from the first main fiber direction, wherein the first main fiber direction (14) and the second main fiber direction (15) are arranged in the plane of the floor (2).
  • this is further achieved by a building with such a floor construction.
  • the first support head has a recess, and the first upper wooden support and / or the first lower wooden support is / are guided through the recess of the first support head, so that the first upper wooden support can be supported directly on the first lower wooden support.
  • the recess ensures that the first column head can rest on the support in the edge region of the recess and, despite the closed storey ceiling, the upper support rests directly on the lower support through the recess without allowing the weight of the upper support to act on the storey ceiling.
  • the first upper wooden support and the first lower wooden support are inserted into the recess of the first support head, so that the first upper wooden support is supported directly on the first lower wooden support within the recess of the first support head.
  • the first lower wooden support is tapered in a stepped manner on the side facing the first support head formed so that the first lower wooden support is inserted into the recess of the first support head, and the first support head rests with the edge of the recess on the formed step of the first lower wooden support.
  • the first lower wooden support and / or the first upper wooden support has a main fiber direction perpendicular to the floor ceiling or the surface side of the first support head. This has the advantage that the support is very stable in the support direction.
  • the first main fiber direction and the second main fiber direction are at right angles to one another and are arranged in the plane of the floor ceiling. Due to the right-angled arrangement, forces in the plane of the column head or the floor slab can be optimally transmitted.
  • the first support head has a plurality of wood layers, wherein in the plurality of wood layers a first wood layer with the first main fiber direction alternates with a second wood layer with the second main fiber direction. Due to the alternating arrangement of the layers with the first and the In the second main fiber direction, very stable plates are achieved in the plane, which can effectively transmit forces in the plane in all directions. This combines the functions of the longitudinal and cross members in the floor ceiling itself.
  • the first wood layer has at least two wood elements lying side by side in the layer plane in the direction of the second main fiber direction
  • the second wood layer has at least two wood elements lying side by side in the layer plane in the direction of the first main fiber direction
  • the at least two wood elements of a wood layer have a wood element of a first type of wood and a wood element of a second type of wood.
  • the layering of different types of wood shown creates areas of the first type of wood, areas of the second type of wood and areas of the first and second types of wood.
  • the first wood layer has three wood elements lying side by side in the layer plane in the direction of the second main fiber direction and / or the second wood layer has three wood elements lying side by side in the layer plane in the direction of the first main fiber direction, the three wood elements of a wood layer alternatingly being a wood element of one have the first type of wood and a wood element of a second type of wood.
  • This embodiment is particularly advantageous if a different type of wood, usually a more stable one, is to be used in the middle than in the edge areas.
  • the support head has at least a first area with a plurality of wood layers of a first type of wood, at least a second area with a plurality of wood layers of a second type of wood and at least a third area with a plurality of wood layers in which the first type of wood and the alternate second type of wood.
  • the recess is arranged in the second area and the second type of wood is more stable than the first type of wood. This is in the area of the recess in which the forces of the floor ceiling, a more stable wood is used than in the edge areas. Thus, the use of expensive wood can be limited to the area around the recess.
  • the floor slab construction has the floor slab that has the first column head and a secondary structure, the secondary structure having a plurality of wood layers, wherein in the plurality of wood layers, a first wood layer with the first main fiber direction coincides with a second wood layer with the second main fiber direction takes turns.
  • the layer thickness and / or the main fiber direction of the plurality of wood layers of the secondary structure correspond to the layer thickness and / or the main fiber direction of the plurality of wood layers of the column head.
  • the secondary structure is connected on the end face to an end face of the prop head.
  • the side structure is arranged at the end with a front side of the column head spaced apart by a gap, and the side structure is connected to the column head in a load-bearing manner by means of an adhesive layer filled in the gap.

  • the uppermost layer of the secondary structure has a main fiber direction that is perpendicular to the main fiber direction of the lowermost layer of the secondary structure.
  • the floor slab construction has a second lower support, a third lower support, a fourth lower support, a second upper support resting on the second lower support, a third upper support resting on the third lower support, a fourth upper support resting on the fourth lower support, the floor further comprising a second support head resting on the second lower support, a third support head resting on the third lower support and a fourth support head resting on the fourth lower support, the secondary structure has four first secondary support parts, which connect two adjacent support heads and has at least one second secondary support part, which connects the four first secondary support parts and forms a closed surface of the floor between the four first secondary support parts.
  • the support head forms a cuboid with two surface sides parallel to the first and second main fiber direction, with two end faces which are arranged parallel to the first main fiber direction, and with two end faces which are arranged parallel to the second main fiber direction.
  • the floor slab construction has the further floor slab on the upper supports.
  • Fig. 1 shows an example of a building 1 with a floor construction according to the invention.
  • the building has a floor slab 3, three floors 2 and an upper floor 4.
  • Each floor slab 2 and 4 rests on at least one support 5.
  • a floor ceiling 2 or 4 rests on at least four supports.
  • Fig. 2 shows an embodiment of a floor ceiling 2.
  • the floor ceiling 2 consists of a plurality of prop heads 6, a plurality of first secondary support parts 7 and a plurality of second secondary support parts 8.

  • Each prop head 6 has a recess 9 which is designed to support an upper prop 5, which is arranged between the floor slab 2 and a floor slab above it, directly on a lower support 5, which supports the floor slab 2.
  • Direct support should mean that the force of the upper support 5 is mainly introduced into the lower support 5 and only a small or vanishing part of the force is introduced into the floor ceiling 2. This can be done by resting the upper support 5 on the underlying support 5 or by resting the upper support 5 on a wood transmission element that has a main fiber direction parallel to the main fiber direction of the upper and lower support 5 and in turn rests on the lower support 5.
  • the weight of the upper floors can be transported directly up to the foundation via supports arranged one above the other, without any of the floor ceilings 2 of the weight of the collected floors lying above one another must be able to withstand.
  • the load of an individual support 5 is no longer limited to the resistance perpendicular to the grain of the floor ceiling, but only by the significantly higher resistance of the supports in the longitudinal direction of the grain.
  • Fig. 3 shows a three-dimensional view of the column head 6 isolated from the floor ceiling 2.
  • the column head 6 forms a plate with two surface sides 10 and four end faces 11. In most cases the surface of the surface sides 10 is larger than that of the end faces 11, but the invention is not limited to this.
