FIELD: construction.SUBSTANCE: to manufacture support-guard elements of dissimilar wall squared beam from undersized wood raw material, a log is rounded up and milled along the outer side with the purpose to give specified shape to finishing material with their simultaneous separation by means of sawing. Then grooves for heat insulation material are milled on the remained two-side edged cant, and support-guard elements of the prefabricated wall squared beam are separated by sawing. The support site of the support-guard element has width equal to 1/3 of width of the two-side edged cant site. Grooves are milled only on the support-guard element. Simultaneously with production of grooves on the two-side edged cant they mill a cog and a slot for a block-house and a cog and a slot for a finishing board. Simultaneously with production of the support-guard element through sawing they produce a guard element, a board of radial sawing, and also a block house and a finishing board. The support-guard element by means of sawing is divided into two parts of equal height. The guard element is fixed to the support element of rectangular cross section, but of different type. Parts of the divided element are installed on the element assembled from different types and fixed by screws. All components are installed by their sap surfaces at one side. Before roundup, log bark is stripped.EFFECT: increased yield of whole wood.8 cl, 1 dwg |
