ABSTRACT:
The invention relates to a push grid comprising grid panels which overlap one another and which are alternately fixed and reciprocable longitudinally of the push grid; grid panel supports provided with a slot-like opening for holding the grid panels; tie members which project through the slot-like opening in the grid panel supports and which, at one end, engage in the associated grid panel; and spring elements arranged between the other end of the tie members and a web of the grid panel supports accommodating the slot-like opening for biassing the connection between the grid panels and the grid panel supports.
In order to obtain reliable fixing of the grid panels to the grid panel support, for example even in the event of an excessive increase in length of the tie members or in the event of breakage of the spring elements, the web (7) with the slot-like opening (6) is arranged inclined relative to the horizontal and the suspension point (14) of the tie member (4) on the grid panel (1) is situated at a greater distance from the lower than from the upper end of the slot-like opening (6) (FIG. 2).
