Abstract

The invention relates to a method for producing a composite wooden structural panel for a building structure, comprising: providing a first wooden structural panel (1), which is load-bearing in two axes, with a first side face (11); coating the first side face (11) of the first wooden structural panel (1) with a stable adhesive (3); arranging a second wooden structural panel (2), which is load-bearing in two axes and has a first side face (21), such that the first side face (21) of the second wooden structural panel collides with the adhesive-coated first side face (11) of the second wooden structural panel, as a result of which an adhesive layer (3) which covers both side faces (11, 21) is formed; and hardening the adhesive layer (3) without compression pressure. At least one of the two side faces (11, 21) has a spacing element (4) which is arranged along at least part of the periphery of the first side face (11, 21) and delimits a flat hollow space. The joined wooden structural panel can be produced at a first location and assembled, preferably glued, to form an end product at a second location. The method is in particular suitable for producing load-bearing building ceilings.

Abstract

The invention relates to a method for producing a composite wooden structural panel for building structures, the method comprising: arranging a first wooden structural panel (10) comprising one or more recesses which extend over a section of a first lateral side and are at least partially delimited laterally by portions of the first wooden structural panel, in relation to a second wooden structural panel (20) such that the portions of the first wooden structural panel (10), which portions delimit one or more recesses, adjoin a first lateral side of the second wooden structural panel (20); filling the one or more recesses with a two-component adhesive; and curing the two-component adhesive. The invention also relates to a composite wooden structural panel comprising two wooden structural panels (10, 20) which are adhesively bonded to one another via the aforementioned cavities (3).

Abstract

The invention relates to a drop panel (1) made of wooden material for supporting and/or carrying wooden structural panels in building structures, the drop panel comprising a main body having an upper face (1.1), a lower face (1.2) facing away from the upper face, and an opening (3) extending from the upper face to the lower face. The drop panel (1) has at least one hollow space (4) which extends at least across a portion of the upper face and is designed to be filled with an adhesive and to comprise an adhesive layer. The invention also relates to a flat slab floor system comprising the drop panel (1), supports (10) and floor panels (30), and to a method for building the system.

Abstract

The invention relates to a method for the elevation of a wooden element, comprising the steps of: cutting to form at least one incision (2) in a surface of the wooden element (1); inserting an expansive material into the at least one incision (2) of the wooden element (1); letting the expansive material expand in the at least one incision (2) so that an elevation of the wooden element (1) is achieved.
