METHOD OF PRODUCING DUAL-SLOPE GLUED-BOARD ELEMENTS Russian patent published in 2011 - IPC B27D1/04 

FIELD: process engineering.

SUBSTANCE: invention relates to construction and may be used in producing dual-slope glued elements with linearly varying cross sections. Proposed method comprises preparing the boards, producing boards stack with applying glue on face and pressing the stack. Dual-slope glued board elements are assembled from separate parts: base (1) and two single-slope elements (2).Note here that two stacks are produced to make a beam. One stack makes base (1) of dual-slope glued board element. Second element is used to produce ridge beams made up of said two single-slope elements (2). Second stack length makes half the length of dual-slope element base. Second stack is sawn over its width to produce two single-ridge trapezoidal shape elements (2). Single-slope elements are jointed together to produce ridge beam to be glued to base (1) of dual-slope element.Single-slope elements are (2) provided with holes arranged at equal distance from faces to receive detachable tie devices for press-fitting of joint.

EFFECT: lower costs.
