Definitions

  • the invention relates to a component for a ceiling construction in Buildings according to claim 1.
  • a device which consists of a concrete slab consists of a partially embedded lattice girder.
  • the upper strap of the Lattice girder stands out from the plate and points down when the component supported on supports of building walls.
  • a blanket for that underlying projectile is made by using a suitable cladding material is attached to the upper belt.
  • From DE-A-211 4 827 is a generic device or a Ceiling construction has become known.
  • a lower concrete layer is a Lattice girder embedded with its lower flange, the diagonal bars following extend upward to an upper concrete layer into which upper straps of the Bearers are embedded.
  • an insulation board arranged below the flat bottom of the top layer.
  • When manufactured in a box shape first cast the lower layer when embedding the lattice girders. Then, with the help of a suitable support structure the Insulating board held, which forms the base for pouring the upper Layer.
  • the insulation board is used for thermal insulation.
  • the invention is based on the object, a component and a Ceiling construction of the type described to improve that it It can be made easier and more versatile.
  • the upper Layer of concrete or a concrete-like substance as a planar element executed without a protruding reinforcement. It relies on protrusions or ribs of the lower layer with the interposition of an elastic Insulating layer on the ribs or the projections.
  • the projections can for example, the upper straps of lattice girders, whose lower girth in the lower layer is embedded. When using ribs these can be formed integrally with the lower layer.
  • the upper layer forms the screed for the overlying building space, while the lower or second layer represents the ceiling for the floor below. Because the upper layer simply placed on the protrusions or ribs of the lower layer is stored, according to the ceiling construction according to claim 10, the lower Layer for support on a support at opposite Building walls used, while the upper layer to the associated Building wall has a gap.
  • the construction according to the invention has a number of advantages.
  • the Production is particularly easy.
  • Components are the concrete layers with their reinforcement initially separate made, after which they are placed on top of each other.
  • Another advantage of the invention is that the space between upper and lower layer can be used in many ways, such as lines and can accommodate pipes for any installation. In known components, where both lower and upper layers have lattice girders, this is relatively cumbersome to accomplish. Also the introduction of suitable insulating materials designed in the device according to the invention easier.
  • the upper layer in a simple way lines for can accommodate a floor heating.
  • the upper layer is a suitable reinforcement, but these will not be lattice girders as in be known components.
  • the introduction of pipes for underfloor heating is therefore particularly easy.
  • a device usually extends between two spaced supporting walls of the building.
  • the distance of the upper Layer of the walls avoids a sound transmission in the bearing Walls into or into the adjacent walls. Within the upper layer naturally takes place a structure-borne sound transmission. This can become the Example disadvantageous, if the upper layer as a floor in two adjacent spaces of a projectile extends.
  • Component according to the invention can also be a sound transmission here Avoid over the floor by placing the top layer with a separating groove is provided in the area of a wall separating the adjacent rooms.
  • the upper layer can there are two or more physically separate sublayers that already produced on the production side and applied. There where one Sound transmission does not have to be avoided, d. H. within a room, For example, the upper part layers can be welded together in a known manner be set against each other.
  • the upper layer on to suspend the projections or the ribs there are various design options conceivable, the upper layer on to suspend the projections or the ribs.
  • One according to the invention provides that on the upper flange of lattice girders of the lower layer of a profile elastic damping material is applied, for example, an inverted U-shaped Profile.
  • a flat strip be welded on steel, on which a strip of elastic Insulating material is arranged.
  • Another embodiment for depositing the upper layer consists in An embodiment of the invention in that U-shaped support plates on the Top of the lattice girders are placed.
  • the insulating layer is on top applied to the web, for example, also fixed by gluing.
  • the legs of the U-shaped support plates overlap the lattice girder on the Top and lie with their thighs against the outside of the diagonal bars at. Therefore, the profile of the support plates is not strictly U-shaped, but Shaped with slightly divergent legs.
  • Such support plates can in Be spaced apart. You have e.g. a length of 30 to 50 cm. The distance between adjacent support plates can be more than that double the length of a support plate.
  • a simpler Attachment consists according to an embodiment of the invention is that the legs of the support plates have indentations or the like which Undercut the connecting area of the diagonal bars on both sides of the upper belt. This undercut is such that when placing the support plates of above the protrusions formed by the indentations the connection area grabbing the diagonal bars snapping behind.
  • the device When applied to a ceiling construction, the device is after a Embodiment of the invention with the lower layer on top of the building walls superimposed.
  • the overlying storey is the Auflagerung the walls on the lower layer, optionally with interposition an insulating layer.
  • the lower plate of the device according to the invention is supported on top of a wall.
  • the length of a table depends naturally according to the distance between the walls of a building room.
  • the Lattice girders can naturally only within the distance of the upper housing walls be arranged. Therefore, there is a risk that the lower longer Plate does not have sufficient strength in the support area. Therefore, according to the invention a second lattice girder is provided whose node to the Nodes of the first lattice girder are offset. This ensures that that regardless of the intended length of a component sufficient support in the support area, either over the first or the second lattice girder.
  • the latter has a lower one Height as the first and is preferably within the first lattice girder inserted. Its length can be limited, as he especially the Reinforcing support area.
  • the component 10 has a first layer 14 made of concrete and an inner one Reinforcement may have (not shown). Top and bottom of the layer 14 are plane-parallel. In vertical distance to a second plate 16 is arranged, which is also plane-parallel, but a lattice girder 18 conventional Training stops, wherein the substrate 20 is disposed in the layer 16 and the upper belt 22 runs above the layer 16 and upper and lower belt 16, 22 are connected by diagonal struts 24.
  • the upper one is Layer 14 is slightly thicker than the lower layer 16. However, the underlayer 16 is longer than the top layer 14 so that it is on top of a building wall 26 can be stored.
  • the above arranged extension of Building wall 28 is supported by a layer of mortar 30 on top of the Layer 16 from or the lower layer of the device 12.

  • FIGS. 1 and 2 It is also apparent from FIGS. 1 and 2 that the manufacture of a component as is easy to do in Fig. 1.
  • the layer 16 with the Lattice girder 18 is conventionally manufactured industrially.
  • After production of the plate-like layer 14 this is raised, rotated and lowered onto the lattice girders 18 with a Overlay on the upper belt as described.
  • An additional safeguard against lateral displacement can be omitted, but it may be appropriate to the Stick layer 14 on the insulating layer 34.
  • FIGS. 4 and 5 are two examples of layer 14 deposition shown.
  • Fig. 4 is a profile strip 40 made of an elastic pressure-resistant Insulating material shown, the approximately inverted U-profile and has on The top strap is placed as shown.
