Brus and beams from an interline interval
SHponovyiy a bar and kleenyie shponovyie beams from LVL — a high-quality constructional material from a tree. Excellent properties of LVL-TECHNOLOGY allow to carry this material to the most perspective, used today in building. The layered structure shponovyih beams does their strong and durable. Defects of separate layers of an interline interval reducing durability, for example knots, are distributed in thickness of layers in such a manner that their influence on durability of an end-product slightly. Thanks to such characteristics asa quality constancy, stability and accuracy of the sizes, straightforwardness, kleenyie shponovyie beams LVL considerably surpass other constructive materials from wood. High prochnostnyie properties kleenyih shponovyih beams LVL are reached thanks to merging of sheets of an interline interval «on a moustache». Thus the set of layers occurs in such a manner that seams of each subsequent layer of an interline interval place in chessboard order in regular intervals on all length of a beam. This system patented by firm Raute Wood, the supplier of the equipment for production LVL, allows to improve prochnostnyie characteristics LVL.
One of unique advantages of material LVL in building is possibility of a wide choice of the sizes shponovyih beams. The width and length of beams can be chosen any way within the sizes supposed by a line on production LVL: kleenyie shponovyie beams LVL can be width in a range from 100 to 180 sm, in the length — from 2,50 to 25 m. the Thickness usually makes 19-75 mm. Aesthetically shponovyie beams look like a wood file that is advantageously used by architects and designers in building. If necessary aesthetic qualities of an item improve further for the account of use of wood of better quality in the top layer of an interline interval.
LVL it is mainly applied in the building industry as bearing support, beams, overlappings and so forth Now many countries earlier using such traditional materials as concrete, a brick, cheaper, effective, power-intensive both ecologically pure construction materials and methods now prefer to use, such as a North American method of building of inhabited and commercial buildings with use of wooden details and components. According to the given technology building occurs to erection of a skeleton of a building on the basis of beams LVL. Further the skeleton is sheathed by wooden panels with use modern shumo - and teploizolyatsionnyih materials. Erection of similar buildings requires considerably smaller expenses and time that is especially important at building in severe climatic conditions when building for a short season is necessary to finish. After definitive furnish the building does not concede under the characteristics (warmly - and sound insulation, durability, durability) to the traditional buildings constructed with application of metal, concrete or a brick. The proof to that is that fact, that practically 90 % of housing accommodation in the North America are under construction in any climatic conditions on the given technology. More often LVL it is used for manufacturing of basic beams for floors (I-Joist), consisting of two bruskov LVL and an intermediate insert from OSB (a plate on the basis of a shaving with the focused arrangement of fibres) or from plywood. LVL also it is used for manufacturing of bearing support and overlappings of the big length.
Convenience and ease of installation — one of advantages LVL before other constructional materials. Processing is made by traditional tools both in production conditions, and on a building site. Installation is made by widely known fixing items, elements of beams incorporate among themselves or to other materials in the traditional method. The small weight of a material allows to refuse application of lifting mechanisms, that considerably makes cheaper building. Of an interline interval and bar LVL produce not only the big and difficult designs, but also doors, windows, ladders, the piece items traditionally executed from a tree as at application of this material high accuracy of conjugated items is reached.
Practically unlimited (to 18) the length at high bearing abilities and prochnostnyih characteristics and the small sizes in section does LVL a universal constructional material.
World experience shows: LVL the bar is more durable, than a wood file, in a timbering, thus kleenyiy the bar from an interline interval supplies ideally equal surface of a monolith.
