Abstract

Klejona belka i płyta z wklęsłymi auksetycznymi komórkami składające się z dwóch zewnętrznych, poziomych pasów (1, 6) wykonanych z drewna nie klejonego lub klejonego typu BSH, C16, C24, KVH oraz z dwóch pionowych słupów (2) wykonanych z drewna nie klejonego lub klejonego typu BSH, C16, C24, KVH, a rdzeń belki stanowią faliste pasy wykonane z tarcicy konstrukcyjnej, najlepiej struganej lub sklejki, płyty HDF, płyty OSB, pasy faliste mogą składać się z symetrycznych ścian (4, 5) formujących wklęsłe powierzchnie przez ich połączenie na złącza miniwczepowe, w miejscach największej odległości między sąsiednimi pasami wklejone są wsporniki o kształcie pryzmatycznym, kołowym, teowym lub każdym innym o przekroju graniastym lub owalnym, wsporniki są wklejane za pomocą dedykowanego dla konstrukcji drewnianych kleju poliuretanowego, wodnego lub innego przeznaczonego do łączenia drewna w suchych i mokrych warunkach, grubość t elementów (4, 5) jest równa od 5 mm do 35 mm co 1 mm, obłogi formowane są w cylindry przez zginanie i klejenie klejem poliuretanowym lub dowolnym dedykowanym dla drewna klejem konstrukcyjnym, mają wilgotność bezwzględną od 8% do 15%, zewnętrzna średnica cylindra D2 odpowiada największej odległości między falistymi pasami od 100 do 400 mm, najkorzystniej 150 mm do 250 mm, wewnętrzna średnica cylindra D1 zależy od grubości cylindra, najkorzystniej grubość cylindra jest równa grubości falistego pasa t najkorzystniej t=T, a grubość wstawek pryzmatycznych tw jest równa od 20 mm do 150 mm co 1 mm, najkorzystniej 100 mm. Wstawki mogą być także kołowe o średnicy odpowiednio D2.Glued beam and plate with concave auxetic cells consisting of two external, horizontal strips (1, 6) made of non-glued or glued wood of the BSH, C16, C24, KVH type and two vertical columns (2) made of non-glued or glued wood of the BSH, C16, C24, KVH type, and the beam core consists of wavy strips made of structural sawn timber, preferably planed or plywood, HDF board, OSB board, the wavy strips may consist of symmetrical walls (4, 5) forming concave surfaces by connecting them with mini-dovetail joints, in places of the greatest distance between adjacent strips, prismatic, circular, T-shaped or any other angular or oval cross-section brackets are glued in, the brackets are glued in using a dedicated polyurethane, water-based or other glue for wooden structures intended for joining wood in dry conditions and wet conditions, the thickness t of the elements (4, 5) is from 5 mm to 35 mm every 1 mm, the facings are formed into cylinders by bending and gluing with polyurethane glue or any structural glue dedicated to wood, they have absolute humidity from 8% to 15%, the outer diameter of the cylinder D2 corresponds to the greatest distance between the wavy strips from 100 to 400 mm, most preferably 150 mm to 250 mm, the inner diameter of the cylinder D1 depends on the thickness of the cylinder, most preferably the thickness of the cylinder is equal to the thickness of the wavy strip t most preferably t=T, and the thickness of the prismatic inserts tw is from 20 mm to 150 mm every 1 mm, most preferably 100 mm. The inserts can also be circular with a diameter D2, respectively.
