FIELD: building structures; designing and manufacture of various bearing structures. SUBSTANCE: wood-adhesive beam has beam proper, one or several composite reinforcement members filled with fire resistant fluid and made in the form of hollow tube provided with holes in its wall which are closed under normal operating conditions with easily fusing plugs. One end of tube is plugged, other one communicates with incombustible fluid storage tank. Metal rods are fitted between plugs and external edge of beam. EFFECT: enhanced ultimate fire resistance and bearing capacity of wood-adhesive structures. 1 dwg
