A bearing beam for convective pack placed in convective shaft of boiler unit is characterized in that it includes own metal beam with rectangular cross section on the side surfaces of which hooks are mounted, and on the lower surface – tee sections and plates made of refractory concrete, in form of rectangular parallelepiped, for lining the side and lower surfaces of the beam, placed in line on the respective surface of the beam and jointed to each other with the side ends with formation of continuous surface of lining. To each plate for lining the side surfaces of the beam reinforcement frame with upper and lower imbedded plates with l-shaped hooks if mounted, the last ones are for suspending to respective hooks of the beam, and the lower imbedded plates with spacer elements. To each plate for lining the lower surfaces of the beam ledges are mounted, those serve for interaction with the tee section. Between the plates and the surfaces of the beam heat-insulation layer is placed. |
