Modular raintank

Abstract

A modular wall panel for an underground infiltration tank comprising a rectilinear periphery formed of four edge members and a plurality of internal strut members which intersect each other at a plurality of junctions. The internal strut members are arranged asymmetrically. The wall panels are provided with load bearing reinforcing nodes, located in at least one junction of the strut members to direct and dissipate the induced forces. The reinforcing nodes are of varying sizes and strength. Several modular wall panels interconnect using complementary studs and holes to assemble an individual infiltration tank module.

1 . A modular wall panel for an underground infiltration tank, comprising:
 a rectilinear periphery formed of four edge members;   a plurality of longitudinally running strut members extending between said periphery edge members and intersecting said edge members at a plurality of junctions;   a plurality of transversely running strut members extending between said edge members and intersecting said longitudinally running strut members and said periphery edge members at a plurality of junctions;   at least one first reinforcing node formed at a plurality of junctions of said longitudinally running strut members and said transversely running strut members and their junctions with said periphery edge members;   at least one second reinforcing node formed at a plurality of junctions, said second reinforcing node being larger in diameter than said first reinforcing node; and   a plurality of diagonally extending strut members extending between adjacent nodes and forming non-parallel arrays with adjacent diagonally extending strut members.   
   
   
       2 . The modular wall panel of  claim 1 , further comprising a plurality of stud members protruding from said periphery edge members. 
   
   
       3 . A modular wall panel for an underground infiltration/storage tank, comprising:
 a rectilinear periphery formed of four edge members;   a plurality of longitudinally running strut members extending between said periphery edge members and intersecting said periphery edge members at a plurality of junctions;   a plurality of transversely running strut members extending between said periphery edge members and intersecting said longitudinally running strut members and said periphery edge members at a plurality of junctions;   at least one first reinforcing node formed at a plurality of junctions of said longitudinally running strut members and said transversely running strut members and their junctions with said periphery edge members;   at least one second reinforcing node formed on said longitudinally rutting strut members, said second reinforcing node being larger than said first reinforcing node;   at least one third reinforcing node located on a plurality of junctions, the third reinforcing node being larger than said first reinforcing node and said second reinforcing node;   a plurality of diagonally extending strut members extending between adjacent nodes and corners and forming non-parallel arrays with adjacent diagonally extending strut members.   
   
   
       4 . A modular wall panel for an underground infiltration tank, comprising:
 a rectilinear periphery formed of four edge members;   a plurality of longitudinally running strut members extending between said periphery edge members and intersecting said periphery edge members at a plurality of junctions;   a plurality of transversely running strut members extending between said periphery edge members and intersecting said longitudinally running strut members and said periphery edge members at a plurality of junctions;   at least one first reinforcing node formed at a plurality of junctions of said longitudinally running strut members and said transversely running strut members and their junctions with said periphery edge members;   at least one second reinforcing node formed on a plurality of junctions, said second reinforcing node being larger in diameter than said first reinforcing node; and   a plurality of diagonally extending strut members extending between adjacent nodes and forming non-parallel arrays with adjacent diagonally extending strut members;   wherein said first reinforcing nodes and said second reinforcing nodes are surrounded by a plurality of supporting web members, said supporting web members interconnecting strut members which abut said first and second reinforcing nodes.   
   
   
       5 . The modular wall panel of  claim 4 , further comprising a plurality of stud members protruding from said periphery edge members.
