Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast brief description of the drawings the utility model.
As shown in Figure 1, comprise according to the three-dimensional grid of the utility model embodiment: multiple nodes and multiple rib,
Described node and described rib are connected to form multiple hexagonal cells,
Each hexagonal cells comprises: six circumferential nodes, described six circumferential nodes are coupled together and form orthohexagonal six circumferential ribs and be positioned at the Centroid at described regular hexagon center successively, described Centroid connects each described circumferential node by a radial ribs respectively;
Six circumferential nodes are respectively circumferential node 11, circumferential node 12, circumferential node 13, circumferential node 14, circumferential node 15 and circumferential node 16, these six circumferential nodes couple together formation regular hexagon, and Centroid 17 connects each described circumferential node by a radial ribs respectively;
The thickness of each circumferential node and described Centroid 17 is identical with shape, and the thickness of described circumferential node and described Centroid is all greater than described circumferential rib, and the thickness of described circumferential node and described Centroid is all greater than described radial ribs.
Because the thickness of each node is greater than the thickness of each rib, in the time that grid is embedded in soil layer or soil, the thickness of each node makes not only to form between grid and filler the tension of horizontal direction or fixing structure, in the time that filler has horizontal sliding tendency, not only each rib produces planar friction power, and resistance and the planar friction power of each node generation vertical direction, thereby increases frictional resistance and the resistance between grid and filler, the pulling capacity that counteracting is deviate from grid, make grid more difficult deviate from.
Further, as shown in Figure 1, the three-dimensional grid of the utility model embodiment forms the rib of three directions, it is the straight line that described multiple rib is connected to form three directions, the straight line of first direction is the length direction of parallel described three-dimensional grid, it is the length direction of the parallel described three-dimensional grid of rib 21 of first direction, the straight line of described second and the 3rd direction and described first direction are 60 degree angles, and the rib 23 of the rib 22 of second direction and the 3rd direction is 60 degree angles with the rib 21 of first direction respectively.
The position of rib of the present utility model and prior art, on the length direction or width of three-dimensional grid, have obvious difference.Prior art is provided with rib at the width of three-dimensional grid, and the utility model does not arrange rib at the width of three-dimensional grid, but on the length direction of three-dimensional grid, rib is set.The length direction of three-dimensional grid is generally operating direction, or experiment, work in expection longitudinal direction.The width of three-dimensional grid is generally horizontal direction, or experiment, work in expection horizontal direction, in Fig. 1, be presented as TD direction.This set of the present utility model, make grid can bear larger longitudinal stretching, or can produce the pulling force on larger length direction, can adapt to like this work-yard that on length direction, needs bear larger pulling force, can reasonable distribution all directions stressed, and, while laying because of grid, generally rolling along its length, this structure can prevent that the warpage going up along its length from appearring in grid in the time that construction is laid.
Further, the thickness of the rib 21 of described first direction is less than the thickness of the rib 22 of second direction and the rib 23 of the 3rd direction, and the thickness of the rib 23 of the rib 22 of second direction and the 3rd direction can be identical.Because the rib in three directions at least exists two kinds of different thickness, make three ribs in direction form rolling three-dimensional tension rib network, increase frictional resistance and resistance between grid and filler.
Further, the rib 23 of the rib 22 of described second direction and the 3rd direction is distortion, increase on the one hand the contact area between rib and filler, increase frictional resistance and resistance between grid and filler, on the other hand, also reduce the moment of torsion between rib and filler, made grid more firm, be difficult for being pulled off or twisting off.
Further, the rib 21 of described first direction is straight, like this, is convenient to make.
Further, the end face of each node is higher than the peak of the end face of each rib, and the minimum point of the bottom surface lower than each rib of the bottom surface of each node, that is to say, from top, each node protrudes from each rib, and from bottom, each node also protrudes from each rib, like this, can, from top and orientation, two of bottoms, increase the frictional resistance between grid and filler, realize dual antiskid and move.
Further, described in the Thickness Ratio of described node, circumferentially the thickness of rib is large.The rib rib thickness proportion of described node and described first direction is 8:2.5 to 8:3.5, for example, be 8:3, and the thickness proportion of the rib of node and second direction is 1.7:1 to 2.3:1, for example, be 2:1.The thickness proportion of the rib of described node and described the 3rd direction is 1.7:1 to 2.3:1, for example, be 2:1.It is outstanding that such proportional numerical value envoy puts the circumferential rib of obvious ratio, can significantly strengthen resistance or the fixation of node to filler.
Further, each described node is hexagon, and in each hexagonal cells, the ratio 1.5:1 to 2:1 of the gross area of described node and the gross area of described rib, for example, be 1.7:1, and this makes node play comparatively outstanding effect to grid entirety stressed.
Further, the isolation transition region that each described rib and each described node intersection have a thickness to increase, each described isolation transition region is for example fan-shaped, and described isolation transition region is kept apart the connection of adjacent each described rib, and the thickness of described isolation transition region is greater than the thickness of each described rib.For example, circumferentially there is the isolation transition region 112 that a thickness increases rib 22 intersections of node 11 and second direction, circumferentially there is the isolation transition region 111 that a thickness increases rib 23 intersections of node 11 and the 3rd direction, at isolation transition region 111 and isolation transition region 112 places, thickness increases suddenly, and the thickness of respectively isolating transition region is all greater than the thickness of each rib.In the utility model, each rib is the stretched portion that belongs to grid, and node is belong to the not stretching of grid or relatively stretch compared with small part, in each described rib and each described node intersection, i.e. and stretched portion and not stretched portion formation isolation transition region.Isolation transition region of the present utility model has ensured the stretching of rib, has also ensured not stretching or few stretching and the thickness of node of node simultaneously, coordinated the part of this stretching and do not need to stretch or few part stretching between relation.
Further, each described isolation transition region is not crossing with the isolation transition region of adjacent rib end.Like this, can control preferably node can not be stretched.Further, adjacent each described isolation transition region intersects, but each described rib mutually disjoints.As long as adjacent rib is non-intersect, each node just can not be stretched, and like this, can ensure that rib has enough stretchings.
The utility model can utilize the preparation method of existing two-way grille, first longitudinally rear cross directional stretch, by adjusting stretching ratio and technological temperature, Nodes is not stretched or different from rib level of stretch, the rib of the rib of second direction and the 3rd direction is stretched for the first time in the time of longitudinal stretching, in cross directional stretch process subsequently, the rib (also referred to as oblique rib) of the rib of second direction and the 3rd direction is stretched for the second time.In twice drawing process, the length direction of the rib of second direction and the rib of the 3rd direction is all different from draw direction, and makes the rib of second direction and the rib of the 3rd direction occur twisted phenomena, thereby obtains three-dimensional grid of the present utility model.
The distortion of rib of the present utility model, the sudden change of node thickness and not being stretched or few stretching, the setting of isolation transition region, all can improve the stress performance of lattice.In the engineering practice of reinforced earth, can make to form and be similar to three-dimensional structure between grid and filler, in the time that filler has slippage tendency, not only produce planar friction power, and produce the resistance of vertical direction, thereby increase the frictional resistance between grid and filler, the pulling capacity that counteracting is deviate from grid, make grid more difficult deviate from, thereby improve the overall stressed effect of reinforced earth, improve stability.
The foregoing is only the schematic detailed description of the invention of the utility model, not in order to limit scope of the present utility model.For each ingredient of the present utility model can mutually combine under the condition of not conflicting; any those skilled in the art; do not depart from equivalent variations and the amendment under the prerequisite of design of the present utility model and principle, done, all should belong to the scope of the utility model protection.
