Description
Technical field
The present invention relates to a kind of GSZ and manufacturing approach thereof, specifically a kind of brilliant multiaxis is to plastic tensile GSZ and manufacturing approach thereof.
Background technology
At present domestic soil reinforcement or the reinforcement material that is used for civil engineering is various in style, its functional performance characteristics, and conforming, each is variant.
Conventional material can be divided into three major types:
One, WARP-KNITTING class: as: polyester fiber or glass fiber use organic protection coating in its surface-coated drying and shaping through being woven into the rectangular mesh structure again.Though this product tensile strength is higher, node strength is lower, and slippage easily causes rectangular mesh malformation, poor stability.
Two, weldbonding class: as: steel and plastic composite material grid, polypropylene tension belt weldbonding grid etc., this series products are after band is processed with composite material by elder generation, vertically, laterally to take and form the rectangular mesh structure, and the node place carries out weldbonding (welding) and forms.This product damages original tensile strength of band easily after welding, cause overall construction intensity to reduce.
Three, plastic tensile class: as: simple tension plastics GSZ, biaxial tension plastics GSZ, three-dimensional stretched plastic GSZ etc.
Above product adopts plastic plate through going out the hole of single row or multiple rows; Its hole be shaped as circle, rectangle, ellipse etc.; Through vertically, laterally progressively stretching or synchro-draw; Thereby obtain the mesh material of rectangle, square, rounded projections arranged, the grid that this structural meterials forms compared with above-mentioned braiding, welding aspect supporting capacity has good integrity, effect that node strength is high, has fully satisfied the requirement of engineering to bulk strength.
But above-mentioned plastic tensile class grid net form is simple in structure: receive force direction less, simple tension plastics GSZ longitudinal strength is big, transverse strength is less, and biaxial tension plastics GSZ has improved transverse strength, but diagonal intensity still a little less than; Each has reasonability to dispersing to three-dimensional stretched plastic GSZ on the pressure improving loading zone, though be triangular structure, intensity is maximum when forming 60 ° at horizontal direction and with horizontal direction, causes product to weaken in longitudinal direction intensity.Therefore the said goods also exists the factors of instability in Application for Field such as highway, railway, water conservancy projectss, causes quality accident easily.
Summary of the invention
In order to overcome above problem, the present invention provides a kind of brilliant multiaxis to plastic tensile GSZ and manufacturing approach thereof, and this product stress is more reasonable; Can guarantee the stability of ground; Have enough tensions, shear strength again, and can prevent soil loss problems such as subgrade settlement.
The scheme that the present invention solves its technical problem employing is:
A kind of brilliant multiaxis is to the plastic tensile GSZ; Comprise Cross slat rod and vertical bar rod; Vertically handing-over forms the rectangular element of the horizontal and vertical array repetition in edge to the bar rod with Cross slat clavus point, is provided with the billet rod in the described rectangular element, and described billet rod is divided into following shape with rectangular element: comprise two trapezoidal; Said two trapezoidal upper bases overlap; Going to the bottom overlaps with two opposite sides of rectangular element respectively, and the trapezoidal summit of going to the bottom overlaps with the rectangular element summit, two opposite sides in addition of said rectangular element and two trapezoidal waists formation triangles.
Above-mentioned GSZ, described trapezoidal be isosceles trapezoid; Further, two trapezoidal be congruent isosceles trapezoid.
A kind of above-mentioned brilliant multiaxis may further comprise the steps to plastic tensile GSZ production method:
A, on plastic plate the punching array, described hole array comprises the unit, hole that repeats to extend along the horizontal and vertical direction of plastic plate, unit, described hole comprises four holes that are at interval circumferential annular array uniformly;
B, the plastic plate after the punching of a step is stretched, make finished product.
Above-mentioned production method, described hole are at least a in triangle, circle, ellipse, rectangle, trapezoidal, the rhombus; Further, described hole is the isosceles triangle hole, and tri-angle-holed drift angle is towards array center.
Above-mentioned production method, described four holes are along the horizontal and vertical four direction up and down that is uniformly distributed in.
Above-mentioned production method, described draw ratio are 2.5-5 times.
Above-mentioned production method is identical along the horizontal and vertical direction adjacent holes of plastic plate cell distance.
Above-mentioned production method is that A and fore-and-aft distance are D along the plastic plate lateral separation between the said adjacent holes unit, and both sizes are D=A ± n, wherein n=0.1mm-10mm.
Beneficial effect of the present invention shows:
1, the brilliant multiaxis has the network structure of special complicacy to the plastic tensile GSZ, and the surface area that has demonstrated fully grid increases, and strengthens with the affinity that contacts of soil.Product is in the stable mechanical property of 360 ° of directions.
When 2, the brilliant multiaxis was embedded in media such as soil, silt to the plastic tensile GSZ, each node of grid and rib band were that the transmission of load provides a series of bearing point and anchor point.Therefore when grid received the active force of medium, it was the rubbing action that relies between grid surface and medium that grid can obtain enough big stress through micro-displacement, also is used for obtaining bigger stress through the interlocked between grid and the medium.Constitute efficient Stress Transfer and reaction mechanism thus, thereby brought into play the brilliant multiaxis, also grappling length is reduced to minimum simultaneously to the maximum reinforcement effect of plastic tensile GSZ.
