Definitions
- the invention relates to a ceiling element for the formation of building ceilings, which is in the form of a wood-reinforced concrete composite part, wherein the ceiling element comprises at least two in a longitudinal direction of the ceiling element parallel to each other wooden beams and a reinforced concrete body, which is resting on the wooden beams plate-shaped Section has.
- Ceiling elements that are designed as prefabricated components in the form of wood-reinforced concrete composite parts are already known in different forms of training. Most of these are formed with a continuous plate-shaped wood Läge, above of a continuous plate-shaped layer
- Reinforced concrete is arranged.
- the disadvantage here is, inter alia, that no installation space is provided for building installations, so that additional suspended ceiling constructions must be used, and that the load capacity is limited.
- a ceiling element of the type mentioned in which two or more parallel wooden beams are provided which extend in a longitudinal direction of the ceiling element, wherein at least two of the wooden beams are spaced apart in a perpendicular to the longitudinal extent of the wooden beams extending horizontal direction. Above these wooden beams, the overall plate-shaped reinforced concrete body is arranged. In this way, an installation space can be provided in the area between the wooden beams through which building installations can be laid.
- such a ceiling element has a high load capacity.
- ceiling elements In comparison to ceiling elements made entirely of reinforced concrete, the required amount of steel can be greatly reduced. Thus, a resource efficient component is provided.
- a problem with structures employing such a prior art ceiling element is the provision of adequate safety in the event of fire.
- Such ceiling elements are usually connected to continuous vertical wooden columns or walls in the areas of the longitudinal ends of the wooden beams. This results in a cross-floor connection through flammable materials. According to today's border management regulations, which set high standards for safety in the event of a fire, this would require additional encapsulation by non-combustible materials or the formation of fire barriers in other ways, which would lead to high additional construction costs.
- the object of the invention is to provide an improved ceiling element of the type mentioned, by which a fire-safe constructions is made possible in a simple manner. According to the invention, this is achieved by a ceiling element having the features of claim 1.
- the reinforced concrete body comprises in addition to the plate-shaped portion which rests on the at least two parallel to each other in the longitudinal direction of the ceiling member extending timber beam of the ceiling member, first and second formed in the form of edge beams sections. These edge beams are angled, for example at right angles, to the wooden beams.
- the first edge beam abuts against the end faces of the first ends of the wooden beams directed in the same direction.
- the second edge beam bears against the opposite end faces of the second ends of the wooden beams, which point in a direction opposite to the direction in which the first ends point.
- the edge bars preferably enclose an angle of at least 45 ° with the wooden beams. In this way, for example, in plan view parallelogram or trapezoidal ceiling elements can be formed.
- the wooden beams are preferably formed of glued laminated timber.
- At least two connecting elements is connected to the respective wooden beams at the two end faces of the at least two mutually parallel wooden beams projecting beyond the respective end face of the wooden beam and in the concrete of the present at this end of the wooden beam Edge beam is embedded. In this way, tensile forces between the edge beam and the wooden beams can be transmitted, whereby the overall load capacity of the ceiling element can be increased.
- bores are formed in the end faces of the wooden beams, in which end portions of the Connecting members are inserted, wherein the end portions are held by a bond in the bores.
- the connecting members advantageously have a rod-shaped part, wherein in the area which is embedded in the concrete of the edge beam, a widening of the connecting member is provided.
- This broadening can be formed for example by a nut which is screwed onto an external thread of the rod-shaped part designed in the form of a threaded rod, or be formed by a head which is fixed to the rod-shaped part of the connecting member. It can be formed by an undercut surface which acts positively against a withdrawal of the connecting member of the concrete of the edge beam.
- depressions are formed on the upper sides of the at least two parallel wooden beams into which protrude projections of the plate-shaped portion of the reinforced concrete body, preferably each of the parallel wooden beams having two or more longitudinally spaced recesses, in each of which a projection of the plate-shaped portion of the reinforced concrete body protrudes. It can be transmitted in the longitudinal direction of the wooden beams acting shear stresses between the wooden beams and the plate-shaped portion of the reinforced concrete body.
- At the tops of the at least two parallel wooden beams connecting parts are connected to the wooden beams, which project beyond the upper sides of the wooden beams and in the concrete of the plate-shaped portion of the
- Reinforced concrete body are embedded. It can be transmitted in the longitudinal direction of the wooden beams acting shear stresses between the wooden beams and the reinforced concrete body. Furthermore, forces acting on the connecting parts in the sense of lifting the respective wooden beam from the plate-shaped section of the reinforced concrete body can be absorbed.
- the connecting parts are designed in the form of screws, which are partially screwed into the wooden beams. Widespread screwdriver benkmü form this Schuetzungsfi Stahlen that act form-fitting against pulling out of embedded in the concrete sections of the screws.
- the ceiling element has a central region located in the region of the longitudinal center of the wooden beams
- Such an elevation can preferably be formed in that the at least two mutually parallel wooden beams in the longitudinal direction have a curved course and the plate-shaped portion of the reinforced concrete body follows this bend (its thickness remains constant).
- the elevation is desirably more than 10mm, with a value of less than 60mm being preferred. Due to this elevation, the long-term creep behavior of the ceiling element (which occurs in the range of 1 to 3 years) can be compensated. Since the carrying capacity of the ceiling element is not adversely affected by the long-term creep behavior, in contrast to the aesthetic appearance, can be dispensed with an over-elevation.
- plastic parts for example polypropylene parts, which can melt in the event of fire, are mixed with the concrete of the reinforced concrete body.
- cavities form, into which water vapor of water bound in the concrete can expand in order to counteract in the event of fire an explosive effect of the water bound in the concrete without such cavities.
- the admixed plastic parts may be in the form of fibers.
- the invention provides an advantageous ceiling element in wood-reinforced concrete composite construction, in which a reinforced concrete body is a plate-shaped gene section and integrally formed therewith sections that form edge beams.

Due to this elevation u, the long-term creep behavior can be compensated so that, in the installed state, the surface of the plate-shaped section 6 is essentially flat after a certain time, which can be, for example, in the range of 1 to 3 years. If design reasons do not oppose this, then the superelevation can also be omitted, ie u can be equal to zero.
