Definitions

  • the invention relates to a wooden ceiling or a wooden ceiling element, which is particularly suitable for floor slabs.
  • beam ceilings which consist essentially of wood, but acoustically very disadvantageous.
  • floor slabs are made of board stack elements, which consist of solid, flat components. They are assembled from boards arranged side by side with nails or hardwood dowels. Alternatively, these can also be glued.
  • the disadvantages of the Brettstapelbauweise are also in a poor sound insulation in the raw state and a problem Auflager impart at ceilings.
  • hybrid ceilings which have wood elements, but are supplemented with concrete on site or in the factory.
  • the disadvantage is that concrete, in particular when introduced on site, introduces much moisture into the building.
  • hybrid ceilings can usually only be installed floor by floor and the drying time can be up to 6 weeks.
  • the object of the invention is to provide an improved ceiling construction, in particular an improved timber ceiling element.
  • the disadvantages of the prior art should be avoided.
  • the invention is achieved by a wooden ceiling with the features of the independent claim.
  • an inventive wooden ceiling element consists of spaced support beams between which connecting elements, in particular boards are arranged.
  • the connecting elements are preferably designed as a stack of boards, as they are also used in a board stack ceiling.
  • the wording that the connecting elements are located between the support beams is to be understood in such a way that the connecting elements reach from one support beam to the adjacent support beam, so that bulk material can be introduced between the support beams.
  • the connecting elements may also have such dimensions or be so long that they connect or cover a plurality of support beams, as described below.
  • the wooden ceiling elements according to the invention are closed at the ends by transversely extending support beams.
  • the transverse support beams can be designed to be load-bearing or non-load-bearing. Depending on the later local use of the wood ceiling element, therefore, the use of a cover board with a smaller diameter can be sufficient.
  • the height of the support bar exceeds the height of the connecting elements, so that between the support bars fillable spaces are formed.
  • any suitable material can be filled, preferably sand, gravel or plastic, special thermal and / or acoustic insulating material or the like.
  • Particularly advantageous is the use of very dry materials, as this, in contrast to conventional concrete floors, significantly less moisture is brought into the building.
  • the material has the highest possible mass.
  • a layer of thermally and / or acoustically insulating material such as glass wool or the like can be introduced into the free space, which is then covered with the bulk material. It is also conceivable that initially introduced bulk material in the free space and a remaining space is then filled with insulating material.
  • the filled free spaces are preferably closed by cover elements.
  • the cover elements can be made of high quality, for example with parquet or laminate and thus serve directly as a floor for the upper floor.
  • the cover elements may therefore preferably also be made of wood, but they can also serve as a construction surface for the further floor construction, for example screed.
  • the properties of the wood ceiling element can be set almost at will.
  • the open spaces can be completely with it Bulk material and, if necessary, other materials are filled, but it may be sufficient to fill them only to 30 to 90%, preferably 50 to 70%.
  • the wood ceiling element according to the invention is preferably made exclusively of wood plus the corresponding filling material. It is also conceivable that the fasteners or even the support bars made of plastic or other materials.
  • a wooden ceiling element according to the invention may have a length of 3 m and a width of 1.25 m in total. It is made up of three horizontally spaced stretcher bars with a height of 0.17 m to 0.36 m. In the longitudinal direction end, respectively transverse support beams are provided at the two end faces, resulting in two clearances between the support beams in this embodiment with a total volume of about 0.341 m 3 , which are filled with bulk material, preferably sand.
  • the width, the height and the length of the support beams and thus also of the free spaces in between are determined by the static requirements of the structure and can be adapted to these.
  • the wood ceiling element according to the invention is covered or closed in this variant by means of a cover element, for example a coarse chipboard (OSB board) or other materials.
  • a cover element for example a coarse chipboard (OSB board) or other materials.
  • OSB board coarse chipboard
  • a ceiling element depending on the density of the wood and the bulk of the bulk material about 200 to 350 kg / m 2 , preferably 250 to 300 kg / m 2 basis weight.
  • weighted standard impact sound level of approximately 75 dB has a value approximately equal to that of equidistant solid ceilings.
  • Using an additional dry screed applied to the wood ceiling elements reduces the weighted normal impact sound level to a level of about 57 dB.
  • the assessed standard impact sound level is reduced even further to 50 dB.
  • a ceiling construction based on wooden ceiling element according to the invention has the potential, in combination with floating dry screeds, to reliably comply with the stricter requirements of DIN 4109 for multi-family dwellings. It is even likely that at more Optimization of the construction also meets the requirements of single-family, terraced and semi-detached houses.
  • the support beams can be connected to each other via connecting means, which are each arranged between two supporting beams. From below each of the support beams and the interposed connecting elements are visible.
  • the connecting elements not only carry the load, but also serve as a kind of screen.
  • the support beams then set, for example, on a single planar connecting element and are firmly connected to this, for example glued, screwed, dowelled or nailed.
  • only the connecting element for example embodied as a visible carrier plate, is visible from below.
  • the wood ceiling element according to the invention can fulfill fire protection requirements such as F30B, F60B or F90B.
  • the fire protection class of the wooden ceiling elements results primarily from the floor level of the wooden ceiling element.
  • a non-load-bearing cover may be provided on the underside, for example formed by a plasterboard or gypsum fiber board or other fire-retardant clothing, whereby the fire protection can be additionally increased.
  • the underside can also be plastered after installation.
  • the support beams may alternatively also be made of steel, which are covered, for example, with plasterboard.
  • wood ceiling element in principle, for all embodiments of the wood ceiling element according to the invention that they can be designed with visible underside (SI) or non-visible bottom (NSI).
  • SI visible underside
  • NBI non-visible bottom
  • the version with a visible underside means that the wooden ceiling element remains visible from below as a floor slab after installation.
  • the wood ceiling element according to the invention is suitable for every floor slab, but also as a roof element for the construction of roofs.
  • a roof element for the construction of roofs.
  • an insulating material such as glass wool may be introduced.
  • the wood ceiling element according to the invention is suitable as a rafter element.
  • the wooden ceiling element according to the invention can be used in particular as a partition between housing units in multi-storey construction.
  • a significant advantage of the filling of the wood ceiling element with mineral bulk material, such as sand, is also in the heat storage capacity of the bulk material. Especially in heating periods, this is very advantageous.
  • an acoustic decoupling is provided between the cover and the support beam.
  • a layer of an elastomeric material can be applied to the support beam, on which in turn the cover is attached.
  • wooden ceiling element provided on the top side with a battens of offending individual boards or beams, wherein the cover is applied to this battens. This also reduces the transmission of structure-borne noise between the support beam and the cover.
  • a combination of an additional material layer for acoustic decoupling and the use of the battens is also conceivable, namely by arranging a battens which has an additional layer of acoustically insulating material, for example an elastomer, on the underside, ie in the direction of the support beams.
  • An acoustic drum effect which possibly results from a free space below the cover element, can also be canceled or at least reduced according to the invention by introducing an additional acoustically insulating material.
  • the cover can also be coated on the underside, ie in the direction of the cavity with an acoustically insulating, preferably elastomeric or soft material.
  • the wood ceiling element according to the invention also has the advantage that installations, such as electrical lines, gas, water or sewage pipes can be arranged easily inside. In particular, they can be preassembled from the factory in the manner of a modular principle, so that the individual wooden ceiling element or the integrated installations on site only need to be connected to each other.
