A plurality of pairs of fifth fixing plates 452 are respectively arranged between the first splice plates 1 or the second splice plates 2 which are connected at opposite positions, and each pair of the two fifth fixing plates 452 is fixed through bolts, so that the first splice plates 1 and the second splice plates 2 can be further fixed. When the furnace bottom plate receives the shearing force, can be through the slip of width direction between first fixed hook 45 and the second fixed hook 451 to can be through first fixed hook 45 and the second fixed hook 451 with shearing force dispersion partly, thereby can reduce the shearing force that receives on the furnace bottom plate, thereby can prolong the practical life of furnace bottom plate.
The implementation principle of the embodiment is as follows: the difference from examples 1 to 4 is that: the two adjacent grid units 3 are connected through the shearing assembly 4, namely, the first fixing hooks 45 and the second fixing hooks 451 are hooked with each other. The first splice plate 1 and the second splice plate 2 can be subjected to a larger tensile force in the longitudinal direction, so that the shearing force can be dispersed by the first fixing hooks 45 and the second fixing hooks 451 to a part, and the shearing force applied to the furnace bottom plate can be reduced, so that the service life of the furnace bottom plate can be prolonged.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
