The present invention relates to a reticular plastic tensile structure, and particularly, to a four directional grating. The grating may be used in civil engineering as a reinforcing and strengthening material, or protection and isolation material. Previous tensile reticular structure materials in the art at least have the following problem: the nodes of the grating are easy to be destroyed, and the grating is not resistant to the tangential force of the solum. It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative. The invention provides a four directional grating comprising: a plurality of nodes and a plurality of ribs, wherein the nodes and the ribs are connected to form a plurality of rectangular units, each of the rectangular units comprises four first nodes located at four vertexes of a rectangle, and a second node located at a diagonal intersection of the rectangle, wherein a line connecting two adjacent first nodes of the rectangle is a side of the rectangle, and each of the rectangular units further comprises a first rib located in the direction of a side of the rectangle to connect two adjacent first nodes, a third node located at a midpoint of each side of the rectangle, a second rib located at a diagonal of the rectangle, and a third rib passing through the second node and connecting the third nodes; the nodes comprise the first node, the second node and the third node; the ribs comprise the first rib, the second rib and the third rib; and the thickness of each of the nodes is larger than the thickness of each of the ribs, wherein the first node and the second node have the same size and thickness. |
