The invention relates to the construction industry and wood processing industry, in particular to the construction of wooden profiled bars.
Known construction profiled beam (p. RF 2173375, C1 from 22.03.2000,), comprising at least two longitudinal rectangular supporting ledge and the s opposite the anchor tabs side beams. In it an integral part of the support of elements defined by the ratio: 0,055 Nand0,27 N.
The disadvantages of timber low performance, limiting the application due to security conditions in the collection of bars with each other through gaps in the horizontal plane, compensating occur when drying deformation between the covering, and covered the base elements (p. RF 2173375, Fig.2), and, as a consequence, the reduction of the shear resistance of vertical and horizontal efforts, arising, for example, under operating conditions in multi-walling the beam, trying to shift the layers of wood.
The closest analogue, selected as a prototype, is the design, construction lumber, disclosed in the patent EP 0787866 A1 (Futaqi, Kohzohi), E 04 2/70, comprising two supporting ledge, a longitudinal mounting grooves for placement of the support elements of the same beam when installing rails on each other, with the installation grooves are located opposite the anchor tabs of the side beams. The support protrusions and the grooves have a trapezoidal cross-sectional profile, and op the technical solutions can be attributed to the relatively low operating properties, limiting use, for example the Assembly of a wall of laminated beams, due to the decrease of durability of structures of timber, because of the symmetrical trapezoidal cross-sectional profile of the support protrusions and grooves on the contacting side surfaces which, when installing the boards of each other, are formed runtestcase force directed vertically along the axis of the beam, which causes a shearing stress on the boundary layers of wood.
Thus, the problem to be solved by the claimed invention is directed, is the compression of the support layers of wood around the edge of the adhesive zones that have been modified in the direction of ravnodeystvuiushchey lateral forces, excluding the occurrence shearing loads.
This task is achieved by the fact that in the inventive construction profiled laminated timber made on two opposite sides and alternating with possible bearing on the lateral surfaces of the support protrusions and the grooves have a cross-sectional asymmetrical trapezoidal profile, a smaller angle towards the vertical axis of the beam to change the correlation of forces and the resultant force at each plane of the seam adhesive connection passes through the ele technical solution, the beam is a laminated wooden beam with asymmetric trapezoidal shape of the support protrusions and grooves, alternating with the possibility of installing beams at each other, each plane of the seam adhesive connection passes through the inclined side surface with a smaller angle.
Thus, the claimed timber meets the criterion of “novelty.”
The comparison of the proposed solutions with other technical solutions shows that multilayer boards assembled with each other at the contact surfaces, made with a different cross-sectional profiles, which are widely known, however, a new set of decomposition and redistribution of the resultant of the contact forces arising during the passage of a seam adhesive bonding through the inclined plane of the asymmetric a-line, a smaller angle towards the vertical axis of the beam and interleaved with the possibility of bearing surfaces when installing the boards of each other, give the area of adhesive bonding a new property, and it is aimed in the direction of the vertical axis of the resultant beam of lateral forces, clutching the edge zone of the contacting bearing surfaces, increases their resistance to deformation and, consequently, the resistance of the fibers to delamination and chipping.
This allows to make a conclusion about compliance solutions to the criterion of “significant ex is ü resistant ledge and groove with the scheme of decomposition of forces.
Glued three wooden planks timber is executed on one side at least two longitudinal support ledge 1 and symmetrically on the opposite side of the longitudinal mounting grooves 2, alternating with the possibility of placing on the inclined side surfaces of the supporting elements of the same timber for the installation of the beams at each other.
The supporting protrusions 1 and the installation grooves 2 are asymmetrical trapezoidal cross-sectional profile, in which the side 3 is inclined at an angleand side 4 - angledto the vertical axis OO of the beam. Through each side 4 passes connecting seam 5 of adhesive bonding. Anglemade more of an angle(>).
When installing rails on each other, for example the wall Assembly, covered and covering the surfaces of the trapezoid arise directed toward each other forces P1 and P2 forming ravnodeystvuiushchey R. If anglemore angle(>) the resultant force R is directed toward the axis OO (Fig.2). This step is ω, in the proposed adhesive beam when installing to a similar beam in the support elements, the resultant of the forces directed toward the center of the beam, clutching the side contact surface, prevents delamination and chipping covering elements, which improves performance.
Building of profiled beam includes made on two opposite sides of the longitudinal supporting lugs and mounting grooves has a cross-sectional trapezoidal profiles, respectively, alternating with possible bearing on the inclined lateral surfaces of the same beam when installing rails on each other, characterized in that the multilayer adhesive trapezoidal beam profile is made asymmetrical, a smaller angle towards the vertical axis of the beam, with each plane of the seam adhesive connection passes through a covered and covering a surface inclined from a lower angle.
