<p>PCT No. PCT/SE81/00357 Sec. 371 Date Dec. 5, 1980 Sec. 102(e) Date Jul. 30, 1982 PCT Filed Dec. 7, 1981 PCT Pub. No. WO82/01906 PCT Pub. Date Jun. 10, 1982.The invention relates to reinforced beam sections produced by forming the cross-sectional configuration of wood particle board, e.g. such as have been provided with bonded-in reinforcing threads (4,5,6,32,48) The latter have thereby been laid in the zones (33,34,45) of the boards where the beam section configuration changes direction during the formation of the beam. Beam sections in accordance with the invention will be light, corrosion-resistant and saving on material as well as having high breaking strength, due to the reinforcement. The field of use for such beam sections is very varied, but among more obvious uses may be mentioned those as beams in housing structures and different kinds of batten in the building trade. A method of laying the reinforcing threads in predetermined zones in the boards is also embraced by the invention.</p> |
