Description

The Invention relates to a wooden ceiling element or wooden wall element consisting made of wooden boards joined together, between each one Insulating body are arranged, wherein on the visible side of the Elements between adjacent wooden boards longitudinal Grooves are formed, according to the preamble of claim 1.

State of the art:

It are wooden board plywood products as load-bearing components for Walls, ceilings, roofs and facades as well as not supporting elements in interior design known. These wooden board plywood products are built according to the wood-block plywood principle, with layers made of softwood are crosswise glued, so that wooden board layers are arranged at a distance. This allows between the made of individual wooden boards made of softwood existing layers along running cavities for receiving installations, Insulations or acoustic absorbers are formed, the Cavities can be designed such that on the visible side of the device between the layers of visible joints remain. However, the production of such components is consuming, since all layers are glued crosswise have to.

By the DE 201 07 152 U1 is a load-bearing, room-high wooden wall element has become known with a distance connected wall parts, in which flocks of longitudinal slats are glued with transverse to these arranged with mutual vertical spacing transverse webs and in the cavities between the longitudinal slats and the transverse webs insulating material is arranged. The flocks of slats are arranged such that, at least on a main surface of the wooden wall element, namely the visible side, joints between the individual slats are present. The vertical, supporting longitudinal slats of a crowd have a mutual distance, which is chosen larger than the diameter of an installation pipe of Rohleitrohrungen. As insulation material wood soft fibers, flax, hemp or rock wool are introduced into the cavities. Due to its high weight, however, this wall element can only be used as such, as it is also expensive in its construction and thus in its manufacture.

Furthermore, by the DE 203 15 506 U1 a prefabricated building structure, in particular a wooden ceiling, with a cover layer, preferably made of wood material and several beam supports, in particular made of wood, known, with several bushings for pipes, cables o. The like. Are provided and wherein the bushings transversely to the main direction of the beam support the building structure are arranged in the region of the neutral fiber.

Of the Invention is based on the object, a wooden ceiling element or To create wooden wall element which is simple in its construction and This is in its manufacture, and what a sound insulation or thermal insulation or both at the same time, for example, the current standards of sound insulation or thermal insulation requirements to fulfill.

The Solution to the problem consists of a wooden ceiling element or wooden wall element of the type mentioned in that every single wooden board of the element on two is plane-parallel opposite sides one each along the wooden board having extending recess which are symmetrical to each other, the wooden board in cross section is double T-shaped with an upper cross member, a lower, the visible side forming cross member and an intermediate bridge is designed and the width the upper cross section is greater than the width of the lower crosspiece is, so that the recesses of two adjacent Wooden boards between them the cavity, in which an insulating body is arranged, as well as in the plan view of the visible side of the element due to the smaller width of two adjacent ones lower crosspieces opposite the larger ones Width of the upper crosspieces joints are formed.

The inventive wood ceiling element or wooden wall element has the advantage of being simple in its construction and the same thereby in its production. Due to the introduced insulating body has the element, according to the insulator used, high sound insulation and / or thermal insulation, so that the item meets today's standards of sound insulation or thermal insulation requirements to be able to fulfill, as for example for public Buildings, such as schools or sports halls o. Ä., Required become. Likewise, the element is due to the introduced insulating body suitable, static requirements even for large Spans to meet.

In Another embodiment of the invention, the wooden boards of the Elements of solid wood and are to be joined together either doweled or glued or bolted together. In this way, in particular a high dimensionally stable and torsionally rigid Function achieved, as well as the production of such elements is considerably simplified, since no glued plywood for the individual slats or wooden boards need to be used. But possess the elements of the invention a building physical and functional high quality and are designed visually appealing.

In a further embodiment of the invention the insulating body either sound-insulating or heat-insulating or both at the same time.

In Another embodiment of the invention, the insulator consist made of wood fibers or plastic. The material becomes advantageous the insulating body according to the application of the element and its purpose selected.

Summary the drawing, in which show:

1 a cross section through five wooden boards, which form a wooden ceiling element or wall element, and between the wooden boards or slats is arranged in each case an insulating body and

2 a perspective view of a wooden ceiling element in plan view of the visible side thereof.

The 1 shows a cross section through five juxtaposed wooden boards or slats 2 , which in their composite a wooden ceiling element 1 or also form a wooden wall element. Every single wooden board 2 is shaped in such a way that it is in cross section on two sides lying parallel to each other one each along the wooden board 2 extending recess 6 . 6 ' having, which to the longitudinal center plane 15 the two planparallel opposite sides are symmetrical, with the wooden board 2 in cross-section double-T shaped is how it looks 1 evident. The longitudinal lateral boundary surfaces 7 . 8th . 9 . 10 and 11 of the wooden board 2 are thus on the opposite side of the same mirror symmetry to the median plane 15 also available. Normally, the height h of the wooden board 2 greater than its width a.

The single wooden board 2 accordingly has an upper cross member 4 , a lower, the visible side of the wooden wall element 1 forming cross section 5 as well as a bridge in between 13 , wherein the width a of the upper cross member 4 greater than the width b of the lower cross member 5 is, so the recesses 6 . 6 ' two adjacent wooden boards 2 form a cavity between them, in each of which an insulating body 3 is arranged. Due to the smaller width b of two adjacent lower cross members 5 opposite the larger width a of the upper cross members 4 two adjacent wooden boards 2 are in plan view on the visible side of the element 1 Put 12 educated.

Preferably, the wooden boards exist 2 of the element 1 made of solid wood; The individual wooden boards are to be joined together either by means of dowels 14 doweled as it is in 1 is indicated. Of course, the wooden boards can also be glued or screwed together.

The cavities open to the outside 6 . 6 ' introduced insulating body 3 are either sound-insulating or heat-insulating or both at the same time. The insulating body used may consist of wood fibers or plastic. which are suitable for use as a sound absorber and for suppressing reverberation.

The visible side forming lower longitudinal surface 16 the individual wooden boards 2 may additionally be concave or convex in the longitudinal direction or roughened, the reflection and thus the sound insulation of the wooden wall element 1 even better and, for example, to suppress reverberation even better.

The elements of the invention 1 are commercially used in particular for interior construction for the production of wooden ceilings and / or wooden walls.
