NO20170258A1 - Building elements for covers, roofs and exterior walls of solid wood panels (2 pcs / double) fastened together with steps of laminated plywood - OSB chipboard or fibreboard - Google Patents

Abstract

Hollow wood element, which can be used both as coverings, roofs and walls in buildings, is made with two solid wood boards bound together with steps. The solid wood boards can be made from glulam boards on a high edge or cross-glued boards. For steps, paralefins or OSB boards are most relevant, but one can also imagine the use of other wood-based boards, possibly also boards made of glulam.

Description

Patent application T-H-Element (Three-hole element) Appendix 1. Explanation.

I have been working on the idea, which consists of making a hollow wooden element with 2 solid wood panels tied together with "steps", for 2-3 years and I think this can have something to do, both as coverings, roofs and walls in buildings.

I run an architectural practice in Møre and Romdsal, and have followed closely the development within wood construction over the past ten years. As a board member and leader of the Møre og Romsdal architects' association in the period 2008-2016, I have been actively involved in the work to increase the use of wood, among other things through project work.

The idea was previously discussed with the Institute of Wood Technology v/head of department Anders Q Nyrud (autumn 2014) and in the last few days. He can be contacted for consultation regarding the originality and possibilities of his idea.

Roughly simplified, it can be presented as a synthesis between the solid wood technology and the technology for the production of I-beam vessels from wood and wood-based material.

The solid wood boards can be made from glued boards on a high edge or cross-glued boards. The latter is probably the best in terms of stability and little shrinkage. For steps, parallel plywood (Kerto) or OSB boards are probably most relevant, but one can also imagine the use of other wood-based boards, possibly also boards made of glulam.

Parallel veneer is probably what gives the best strength.

Claims (2)

A. Advantages of the product as a cover and roof: 1. Light and rigid element, greater span in relation to the amount of material than ordinary solid wood. 2. Wide range of dimensions and element widths with the same technology. 3. Low U-value with cavities filled with insulation. 4. Great freedom in the use of insulation material. Wood fiber insulation very relevant due to fire protection from the solid wood boards. Dimensioning of these in relation to fire requirements. 5. Holes in the ladder give great freedom in relation to the presentation of installations. 6. Parts of the hole can be filled with lean concrete, clay or other heavy material for better acoustic properties. 7. Element can be produced with parts at a lower height for adaptation to wet room floors. 8. In general, the technology gives great opportunity to obtain interior surfaces of wood without covering. 9. Favorable technology with regard to factory production and little work on the construction site. Same advantages as solid wood in general in relation to the environment on construction sites. 10. Favorable technology in relation to minimal thermal bridges at layouts and junctions. 11. For the roof element in particular: The top solid wood panel can collar out and shape the roof joint. 12. Can bring wood as a material in supporting constructions even more steps forward in competition with other materials. 13. Gives new meaning to the term "wooden hole covers", which until now has been used to refer to elements assembled from truss beams with nail plates and boards or boards. B. Advantages of the product as an outer wall: The technology probably has the greatest potential for decks and roofs, but should also be interesting to consider as external walls. The outer wall elements can have a greater distance between the steps for smaller thermal bridges (600 mm or more). Many, perhaps most, of the benefits mentioned under covers and roofs cover debt and external walls. Here, advantages are taken that apply specifically to external walls. 1. High stiffness and interaction between the outer and inner layers of solid wood due to the steps, without more thermal bridges than in a traditional half-timbered wall of I-profiles. 2. Great freedom when choosing insulation material. Wood fiber insulation will be well protected against moisture and fire by the solid wood panels (such as for decks and roofs) 3. Unnecessary vapor barrier layer and possibly additional windproofing on the outside. 4. On walls that are little exposed to weathering, external cladding can probably be omitted. 5. Well suited for the integration of windows and external doors in the wall elements, thus little work with assembly and adaptations on the building site. 6. The solution with insulation between two exposed layers is well suited for the layout of balconies and corridors without thermal bridges and anchoring/fastening that goes through the insulation. 7. The principle also provides good prerequisites for avoiding thermal bridges when anchoring to foundations, ring walls and basement outer walls made of concrete or brick.

The drawings on the plans, annexes 2 and 3, show principles and details that illustrate most of the points in the foregoing. C. Internal walls. 1. Elementa can be advantageously used for high walls where the rigidity comes into its own, for Døme's load-bearing walls in sports halls, industrial buildings and the like.
