Abstract
A triangular mesh grid comprises a plurality of main nodes and three groups of ribs, wherein the three groups of ribs extend along three different directions on the same plane, and the ribs in the same group are parallel to each other; the main node is the intersection point of the three ribs in different directions, and the adjacent three main nodes and the ribs connecting the three main nodes form a tensile triangle; and the direction of one group of ribs is parallel to the longitudinal direction of the triangular mesh grid. Therefore, the triangular mesh grid can keep stronger structure stability when being stressed in different directions.
Description
Technical field
The utility model relates to a kind of grid, particularly relates to a kind of netted grid of triangle that can keep stronger structural stability.
Background technology
Grid is two-dimensional mesh trellis that forms through thermoplastic or mold pressing with high molecular polymers such as polypropylene, polyvinyl or the 3 D stereo grid screen with certain altitude, when using as civil engineering, is called GSZ.
GSZ is a kind of main geosynthetics, compares with other geosynthetics, and it has particular performances and effect.The GSZ muscle material of earth structure or the muscle material of composite material etc. done commonly used.GSZ is divided into the plastics GSZ, steel is moulded GSZ, earth grille and glass polyester GSZ four big classes.
The plastics GSZ is the polymeric web material of the square or rectangle of having of stretched formation, and difference of draw direction can be two kinds of simple tension and biaxial tensiones when making by it.It is to go up punching at the polymer plate of making through extruding (mostly raw material is polypropylene or high density polyethylene (HDPE)), under heating condition, implements orientation stretching then.The simple tension grid only stretches along the sheet material length direction and processes, and the biaxial tension grid then is to continue the grid of simple tension is processed in the direction stretching vertical with its length again.
Because the plastics GSZ macromolecule of polymer in the mill can be arranged orientation again with heating extension process, strengthened the connecting forces between strand, has reached the purpose that improves its intensity.Its elongation per unit length has only 10%～15% of former sheet material.If in GSZ, add anti-aging materials such as carbon black, can make it have endurance qualities such as acidproof preferably, alkaline-resisting, corrosion-resistant and anti-aging.
Unidirectional GSZ is to be pressed into thin plate again towards regular hole pattern by high molecular polymer through extruding, and longitudinal stretching forms then. 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. and this kind structure has quite high hot strength and stretch modulus.
Two-way GSZ be with high molecular polymer through extruding, become after plate, the punch process more vertically, cross directional stretch forms.This material all has very big hot strength on vertical and horizontal, this structure equally also can provide the desirable locking system of bearing and spreading of a more efficiently power in soil, is adapted to the ground of the permanent carrying of large tracts of land.
Biaxial tension plastics GSZ is applicable to various dykes and dams and roadbed reinforcement, side slope protection, hole wall reinforcement, the foundation reinforcement of permanent carryings such as large-scale airport, parking lot, harbour goods yard.
1. increase the road () bearing capacity of base, prolong the road () application life of base.
2. prevent the road () face subsides or cracks, and keeps ground attractive in appearance neat.
3. easy construction saves time, and is laborsaving, the reduction of erection time, reduces maintenance cost.
4. prevent that culvert from cracking.
5. the enhancing slight slope prevents erosion.
6. the minimizing cushion thickness is practiced thrift cost.
7. support the stable greening environment of side slope grass planting net pad.
8. the instead wire lath is used for false top net under the coal mine.
According to the difference of the mode of production, GSZ can be divided into plurality of classes.Like the criss-cross net structure that forms through braiding with polyester fiber or glass fiber, again at its surface-coated PVC material.Perhaps with the criss-cross net structure of plastic tensile band through being welded.The node strength of above-mentioned two types of GSZs is lower, and structural stability is relatively poor, actual complex receive in the force environment be difficult to the soil body is played effective reinforced action.Again perhaps through criss-cross net structure to forming after the plastic plate biaxial tension after the punching.Though such GSZ can provide stronger tensile strength at vertical and horizontal, and have higher node strength, still comparatively ideal structural stability can't be provided in diagonal.
For traditional rectangular grid 2, when bearing oblique orientation load, need through node with 90 degree angles respectively to the rib transmission of both direction, and the moment of torsion that this node bears can be very big, just there is the possibility of tearing more greatly in node.As shown in Figure 1; When the node 21 of grid receives from oblique during with two identical load F longitudinally at the same time; Its pairing rib 22 is except that bearing from the tensile force f longitudinally; Also will bear inclined load component f in a longitudinal direction, its F+f that makes a concerted effort is about 1.7 times of longitudinal force F, and causes its node 21 easily by tear failure.
The cancellated GSZ of above-mentioned criss-cross, though at vertical and horizontal certain tension effect can be provided, active force not necessarily comes from merely on the vertical and horizontal both direction in the reality.If actual force is applied to obliquely, then there is great unstability in this structure.
