FLOW TABLE (CONCRETE)-1000 X 1000 MM

The flow table apparatus will be constructed in accordance with fig.1A and 1B of IS 9103 flow table top will be Constructed from a flat metal plate of minimum thickness 1.5mm.The top will have a plan area of 1000mm x 1000mm and a flatness of within 1.5mm The center of the table will be scribed with a cross, the lines of which run parallel to and out to the edges of the plate and with a central circle 200mm in dia meter The under surface of the plate will be reinforced in order to prevent distortion of the flat surface The front of the flow table top will be provided with a lifting handle as shown in Fig .1.

The flow table top will be hinged to a base frame using externally mounted hinges in such a way that no aggregate can become trapped easily between the hinges or hinged surfaces. The front of the base frame will extend a minimum 120mm beyond the flow table top in order to provide a top board, An upper stop similar to that shown in Fig. 1A will be provided on each side of the table so that the lower front edge or the table can only be lifted 40 ± 1mm

The lower front edge of the flow table top will be provided with two hard rigid stops which transfer the load of the base frame The base frame will be so constructed that this load is then transferred directly constructed that this load is then transferred directly to the surface on which the flow table is placed so that there is minimal tendance for the flow table top to bounce when allowed to fall
