DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is national phase of PCT/EP95/01112 filed 24 Mar. 1995 and based, in turn, on German national applications P 44 10 535.5 filed 26 Mar. 1994 and P 44 10 534.7 filed 26 Mar. 1994 under the International Convention.
The present invention relates to a wood or timber connecting system for wooden structures, such as pergolas, open garages, bus shelters, etc. The invention also relates to a wood or timber connecting element for connecting vertical posts and wooden beams fixed substantially perpendicularly thereto.
BACKGROUND OF THE INVENTION
Frequently in the case of fences, pergolas, open garages and the like, use is made of round timbers or timber, concrete posts, to which is then fixed the wooden beam as a girder for a fence panel or side wall, e.g. for a garage. The connection between the post and the wooden beam normally takes place by means of mechanical parts, such as hinges, screw connections, brackets, etc. All these elements suffer from the disadvantages that they damage the wood of the post assembly is complicated, a flexible adaptation to the most varied shapes and easy disassembly and modification are not possible.
The connection of the individual timber components of the aforementioned wooden structures conventionally takes place by means of brackets, screw connections or structural notches in the individual components. With such wooden structures it is a common problem to have to connect or join vertical supports, which are frequently made from round timbers or from concrete, and horizontal components arranged substantially at right angles thereto and which are known as main girders. The main girders can also carry secondary girders. It is disadvantageous in the hitherto known fastening and fixing modes, that on the one hand there is no structural wood or timber protection, because wooden parts can be damaged or surfaces occur in the wood on which water can collect and can lead to the premature destruction of the wood, and on the other hand it is difficult to bring about a variable structural form differing from the right-angled ground plan.
GB 2 005 325 A discloses a metallic connecting element for the connection or joining of metal fences, which has a ring band open on one side and whose internal diameter substantially corresponds to the external diameter of the post. Mounting or fastening straps are shaped onto the open ends of the ring band for fastening purposes and between them can be fastened a fence element. The fastening straps are wider than the ring band. Thus, on one post it is possible to use two connecting elements, which are rotated by 180.degree. about the longitudinal axis thereof relative to one another. One connecting element points in one direction and the other connecting element in the other direction. Therefore the two connecting elements can be fastened to the post in tightly engaging manner without there being any vertical displacement of the individual fence panels. Upon rotation through 180.degree. about the longitudinal axis, the fastening means in the fastening straps are arranged axially symmetrically.
DE 586 379 discloses a device for fastening fence members, which has a U-shaped construction and on the base is mounted a rotary manner on a fastening element for fitting the device to a post. As a result of the rotary mounting random angles with respect to the post can be obtained in a simple manner.
OBJECT OF THE INVENTION
The object of the present invention is to provide a timber connecting element and timber connecting system appropriate for wooden construction, which allows a simple assembly and modification, while keeping to a minimum the damage to the individual timber components.
SUMMARY OF THE INVENTION
The timber connecting system of the invention which achieves this object, has a first connecting element between a vertical post and a horizontal wooden beam, which engages in circular manner around the post by means of one or more ring bands and can be fixed to the wooden beam by fastening straps
