Abstract
The utility model relates to a steel-plastic sticking-welding geogrid which comprises longitudinal ribs and transverse ribs, wherein the longitudinal ribs and the transverse ribs are vertically arranged in a staggered mode and made of steel. The cross points of the longitudinal ribs and the transverse ribs are fixedly welded. Plastic layers cover the longitudinal ribs and the transverse ribs. In order to prevent the welding points from getting frozen and crazing, the welding points of the longitudinal ribs and the transverse ribs are bound by high-strength fiber material or metal wires. PVC layers coat the plastic layers, and back glue coats the upper surfaces of the PVC layers, and glass fiber non-woven fabrics are glued to the back glue. The glass fiber non-woven fabrics not only can enhance the intensity of the geogrid, but also has the characteristics of waterproofing, cracking prevention and the like. According to the steel-plastic sticking-welding geogrid, plastic material serves as the protective layers, the effects of ageing resistance and corrosion resistance are achieved, the anti-freeze capacity is high, tensile strength is high, and the steel-plastic sticking-welding geogrid is adapted to the poor working conditions of the north of China.
Description
Technical field
The utility model relates to a kind of steel and moulds the weldbonding geo-grid.
Background technology
North infrastructure construction is higher to material requirements, but the etching characteristic requirement that not only needs to have the adverse circumstances such as acid and alkali resistance, salt, but also need to satisfy the frost resistance requirement.Traditional product can not adapt to its working environment, and temperature Change is large, and easily bursting by freezing and oxidation, so the product that a kind of tensile strength of market demand is high, overall performance good, elongation rate is little can solve settlement of subgrade and treatment of soft foundation.
The utility model content
Technical problem to be solved in the utility model is to provide the steel that a kind of freezing tolerance is strong, hot strength is high and moulds the weldbonding geo-grid.
For solving the problems of the technologies described above, the utility model provides a kind of steel to mould the weldbonding geo-grid, comprise:: the longitudinal rib that is formed from steel and the transverse ribs of vertical interlaced setting, the crosspoint of described longitudinal rib and transverse ribs is welded and fixed, and is coated with plastic layer on described vertical, horizontal rib.
Further, for preventing weld because of the cracking of enduring cold, high fiber strength strains or wire binding are adopted in the crosspoint of described vertical, horizontal rib.
Be coated with the PVC layer on described plastic layer, the upper surface of PVC layer scribbles gum, is stained with glass fibre non-woven on gum; Glass fibre non-woven can not only strengthen the intensity of geo-grid, has also had waterproof, the characteristics such as cracking resistance line.
Technique effect of the present utility model: steel of the present utility model mould the weldbonding geo-grid with plastic material as topping, reach anti-aging, corrosion resistant effect, and freezing tolerance is strong, hot strength is high, adapts to the abominable working environment in the north.
Description of drawings
Below in conjunction with specific embodiment, the utility model is described in further detail:
Fig. 1 is the structural representation that steel of the present utility model is moulded the weldbonding geo-grid;
Fig. 2 is the tangent plane schematic diagram of Fig. 1.
The specific embodiment
As Fig. 1-2, the steel of the present embodiment is moulded the weldbonding geo-grid and comprised: the longitudinal rib that is formed from steel 1 and the transverse ribs 2 of vertical interlaced setting, described longitudinal rib 1 is welded and fixed with the crosspoint of transverse ribs 2, is coated with plastic layer 3 on described vertical, horizontal rib.
Further, for preventing weld because of the cracking of enduring cold, high fiber strength strains or wire binding are adopted in the crosspoint of described vertical, horizontal rib.
Be coated with the PVC layer on described plastic layer, the upper surface of PVC layer scribbles gum, is stained with glass fibre non-woven on gum; Glass fibre non-woven can not only strengthen the intensity of geo-grid, has also had waterproof, the characteristics such as cracking resistance line.
Obviously, above-described embodiment is only for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among protection domain of the present utility model.
Claims (3)
1. a steel is moulded the weldbonding geo-grid, it is characterized in that comprising: longitudinal rib and transverse ribs that vertical interlaced arranges, the crosspoint of described longitudinal rib and transverse ribs is welded and fixed, and is coated with plastic layer on described vertical, horizontal rib.
