Description

The invention relates to the woodworking industry, in particular to the production of glue-wood structures

The known method, the production of glued beams from coniferous wood plates, including the planing of the glued planes, the application of the binder. Laying the plates on top of each other and pressing them in. A method of manufacturing glued wooden structures is also known, which includes mechanical processing of sheets of tapes, applying a binder, forming a bag and pressing it. A disadvantage of the known methods in lats is the low strength of glued wooden structures. The purpose of the invention is to increase the strength of glued wood constructions that are exempt in variable temperature-humidity conditions. This is achieved by the fact that the mechanical processing of the layers is carried out with the additional formation of recesses parallel to the side edges of the layers, the depth of which is not less than the thickness of the layer of early wood. made continuous over the length of the plate or intermittent, can be made of variable depth, with variable or constant pitch, recesses can be made conical sections, recesses in adjacent glued layers can be displaced across the width of the plate one relative to the other, recesses can be made obliquely or perpendicular to the glued shkhast mine. The drawing shows a diagram of a glued wooden structure, type of joint. Glued wooden structures, produced by this method , include ribbons 1 with layers 2, which have 3 cavities located parallel to the side of the edges, the latter being continuous or intermittent for the length of the plate 2, while the depth of the cavities A ne The width and width of the plate 2 are arranged with variable or constant pitch, the cross section of the grooves 4 is tapered, and in adjacent glued beds x 2 the grooves 4 are offset across the width of the plate one relative to the other, and the grooves 4 are inclined to the glued bed 2 or perpendicular. Example of the method. Softwood sawnwood blanks were joined to a notched tenon along the length of the strips 1 and their layers 2 were machined, which was formed with an additional parallel formation. 3 lateral edges of the edges 2 recesses 4, the depth of which is not less than the thickness of the layer of early wood, recesses 4 being made while preserving the wood fibers by pressing the discs into the glued surfaces of the tapes. After forming the tapes 1, recesses 4 applied the binder, formed a package and pressed it, and the cycle is repeated. The presence of transverse adhesive bonds in glued wooden structures increases their resistance to splitting and chipping along the glue seams and increases the durability of structures during their operation in ennyh-temperature conditions vlagknostnyh
