PURPOSE:To mount a lining plate 3 directly on the upper parts of horizontal joint materials and to reduce the space as far as possible by forming monolithically lining plate-holding beams correspondent to holding beams and construction reinforcing sections correspondent to upper. machines of pair inclined structures. CONSTITUTION:Main girders 1 constructed in parallel with each other are connected with horizontal joint materials 2 at right angles to them at a plurality of longitudinal positions, and a lining plate 3 is directly laid on the upper parts of the joint materials 2. In the case the main girders 1 are horizontally jointed with each other, reinforcing joint sections 17 are positioned downward from the upper levels of the main girders 1, interlocking seat sections 6 are positioned upward from the upper levels of the main girders 1, so that parts positioned to the lower positions of the horizontal joint materials 2 are operated as construction reinforcing sections 30 constituted of part of pair inclined structures 25 and 26 on the basis of the upper levels of the main girders 1, and parts positioned to upper positions are operated as lining plate holding beams 31 for bearing the lining plate 3. For that purpose, holding beams are not required, and the lining plate can be directly mounted on the upper parts of the horizontal joint materials. |
