Abstract

Holm for forming a bed frame consisting of a glued layer structure of individual longitudinal beams of natural renewable material, characterized in that bamboo serves as a material and the individual longitudinal members are formed to the layer structure of longitudinally split tube segments (2) of a bamboo tube, which essentially as square elements ( 1) and longitudinal beams for layer construction per layer (3, 4) in vertical or horizontal position based on the production of the split pipe segments (2) of the arranged square elements (1), wherein square elements (1) arranged one above the other from one layer and the layer structure formed by a plurality of layers (3, 4) and adjacent layers (3, 4) partially formed by layers with different layers of the square elements (1) and to form a spar (5) all square elements (1) and the adjacent layers glued together and pressed together.

Description

The innovation relates to a spar for forming a bed frame consisting of a glued layer structure of individual longitudinal beams of natural renewable material.

It is known to form wooden beams in the layer structure to use these for bed frames. The raw material wood is relatively expensive and also the weight of the formed bed frame is high, so that there are disadvantages compared to other materials.

It is therefore the object of the innovation to use a rapidly renewable raw material, which has the required strength to form bed frame and has a lower weight and at the same time a low price.

The solution of this object is according to the innovation in that bamboo is used as a material and the individual longitudinal beams are formed for layer construction of longitudinally split tube segments of a bamboo tube, which are essentially worked out as square elements and side members for layer structure per layer in vertical or horizontal position relative to the Manufactured from the split pipe segments of the arranged square elements formed, wherein square elements are arranged one above the other, and the layer structure formed by multiple layers and adjacent layers partially formed by layers with different layers of the square elements and to form a Holmes all square elements and the adjacent layers together glued and pressed.

As a result, an advantageous arrangement for using bamboo is created, which ensures a permanent load by a combination effect of assigning different layers and the gluing as so-called horizontal and vertical bonding. It is thus combined by the individual layers of high elasticity and with a strong deflection in the fiber direction of the bamboo used by layers with a high rigidity and low deflection.

In order to provide a further improvement, it is proposed that the connecting regions of the square elements of adjacent layers are arranged offset from each other from the same positions of the tube segments of square elements.

An advantageous solution is that at least three layers of horizontally assigned square elements and the outer areas are each formed by at least one layer of vertically assigned square elements.

It is further provided that the adjacent layers of square elements are arranged with partially different width.

In the drawing, an embodiment of the innovation and a formation of the square elements are shown schematically. Show it:

1 a basic process for the production and optional assignment of the square elements and

2 a structure of a spar of individual layers

When using bamboo, it should be noted that this results from a telescopic length growth. There is no secondary thickness growth corresponding to a tree. Furthermore bamboo is hard on the outside and soft on the inside.

To obtain appropriate square elements 1 the bamboo tube becomes segments 2 split and from the individual segments 2 a square element 1 worked out. The formed square elements 1 are assigned vertically or horizontally to each other and thus form vertical layers 3 and horizontal layers 4 ,

In the illustrated embodiment, a spar 5 from three internal horizontal layers 4 and each outer layer arranged vertical layer 3 educated. Here are the individual square elements 1 with each other and the individual layers 3 . 4 glued together and pressed together, so that a solid composite as a spar 5 arises.

To improve the square elements 1 adjacent layers 4 in the same horizontal position 3 with their connection zones 6 arranged offset from one another.
