Abstract
The utility model discloses a unidirectionally stretchable plastic geogrid, which has a certain length and a certain width and comprises longitudinal polyethylene bar bundles and transverse polyethylene bar bundles, which are uniformly distributed and conduct functions of rib bands. The unidirectionally stretchable plastic geogrid is characterized in that: the transverse bars are joints of longitudinal bars; and the transverse bars and the longitudinal bars form continuously extended and mutually connected rectangular grid units. As the joints are integrated into a whole, the longitudinal stress bearing capacity is very high. Meanwhile, because the product is wide, the construction is easy, the joints and join seams of the unidirectional geogrid are reduced, and the strength loss between the joints and the join seams is reduced.
Description
Technical field
The utility model civil engineering material is specially a kind of simple tension plastics GSZ.
Background technology
The simple tension GSZ be a kind of be primary raw material with the high molecular polymer; Add certain antiultraviolet, anti-aging auxiliary agent; Make original distribution chain molecule at random redirect arrangement through simple tension and be linear condition; Be pressed into thin plate again towards regular hole pattern through extruding, then the high strength geotechnique material that forms of longitudinal stretching.Make macromolecule become the direct line sexual state netted globality structure of oblong that also formation is evenly distributed, node strength is high in this process.
This kind structure has quite high hot strength and stretch modulus, but tensile strength can only reach 100-200Mpa.
Existing unidirectional GSZ fabric width is smaller, is difficult for construction, and speed of application is slow, and the existing splicing in two GSZ junctions makes the loss of strength that exists between joint and the piece, and under whole large tracts of land situation, intensity is influenced easily.
Summary of the invention
The utility model is to above weak point, and a kind of high strength, simple tension plastics GSZ that fabric width is big are provided, and carries bigger tension, anti-shear ability.
For achieving the above object, the utility model adopts following technological means:
A kind of simple tension plastics GSZ; Described grid comprises even distribution and plays the vertical bar cluster and the Cross slat cluster of the polythene material of muscle band effect; Wherein the Cross slat rod is the node that crosses of vertical bar rod, forms to extend interconnected square-grid unit continuously.
Above-mentioned GSZ, the width >=2.5m of said GSZ.
Further, described grid width >=3m.
The beneficial effect of the utility model shows:
This shows that this grid is unidirectional (vertically) grid, be characterized in that the stress of vertically being born is very high, node forms an integral body (Cross slat rod), and is very firm, not fragile.
The goods fabric width is big, construction easily, and progress is fast, has reduced the joint and the piece number of unidirectional GSZ, has reduced the loss of strength between joint and the piece, has guaranteed that whole large tracts of land intensity is unaffected.

The specific embodiment
As shown in the figure; A kind of simple tension plastics GSZ, described grid has certain length and width: width >=2.5～3m, length is reduced as required; Vertical bar cluster and Cross slat cluster that it comprises even distribution and plays the effect of muscle band; Wherein the Cross slat rod is the node that crosses of vertical bar rod, forms to extend interconnected square-grid unit continuously, and this geotechnological grid adopts polythene material to process.
Claims (3)
1. simple tension plastics GSZ; Described grid comprises even distribution and plays the vertical bar cluster and the Cross slat cluster of the polythene material of muscle band effect; It is characterized in that: wherein the Cross slat rod is the node that crosses of vertical bar rod, forms and extends interconnected square-grid unit continuously.
2. GSZ according to claim 1 is characterized in that: the width >=2.5m of said GSZ.
3. GSZ according to claim 1 and 2 is characterized in that: the width >=3m of said GSZ.
