Abstract

The utility model is an anchored net, which is made into trapezoidal corrugated steel strip bar using the steel strip of abrasion resistant steel, stainless steel and plain carbon steel via die stamping, then a hexagon is composed of the steel strip bars by linking to each other, the anchored net is characterized in that each steel strip bar is composed of a number of uniform minimum units of steel strip bar formed by die stamping, two uniform riveting holes (7) are arranged at the side of the upper riveting hole (2) of each unit of steel strip bar, the right side and left side of the steel bar unit are provided each with an outer earth claw (5) and an inner earth claw (6), an outer earth claw hole (9) and an inner earth claw hole (10); the side of the lower riveting claw (4) is provided with a riveting claw (8), the riveting claw of each steel strip bar links into the riveting hole of another steel strip bar, the anchored net is composed of a number of steel strip bars by linking to each other. Thereby the liner material inside the mesh of the anchored net is fixed more effectively, the anchored capability of the liner material is increased markedly, and the service life is prolonged.

Description

A kind of anchoring net

Technical field:

The utility model relates to oil, chemical industry, electric power, steel industry lining metal structure anchor spare, a kind of anchoring net.

Background technique:

At present, the extensive use in numerous items such as oil, nitrogenous fertilizer, big sulfuric acid, large thermal power plant of anchoring net, and obtained good effect, according to different needs, it can use Wear Resisting Steel, stainless steel, the steel band of Common Straight Carbon Steel is assembled into various models through punching press, the anchoring net of outer appearance curvature of the spinal column portion directly perceived, this all porose mutual UNICOM of anchoring net hexagon, flexible radian.Materials such as, corrosion resistant fire-resistant, wear-resisting in matrix inwall point postwelding cast can increase the adhesion of material, make service life of equipment improve several times, and mould material can not peel off, and the unlikely obstruction of discharge gate reaches the effect of getting twice the result with half the effort; In large thermal power plant because without the equipment of the ferrous materials of any protection; parts are subjected to the corrosion with sulphur, steam of washing away of coal dust for a long time; serious restriction the safety in production and life of equipment; at transfer hopper lining and hot-flow flue; the gateway of horizontal ball mill, mill exhauster, induced draught fan, the crust of weathering, thickness unicom pipeline; one time anchoring net and fire-resistant, wear-resisting, the anti-corrosion material wear resistance lining of casting are used in positions such as wind coal pipe elbow, have obtained gratifying effect.

Mud pawl on its limit, side of existing anchoring net is a single direction, all at inner side surface, and has only one, like this since whole anchoring net be not very big for the adhesion and the fastening effect of lining material.

Summary of the invention:

For overcoming the technological deficiency of existing anchoring net, the purpose of this utility model provides a kind of anchoring net, makes its more effectively interior lining material of mooring anchor fixed network mesh, strengthens the anchoring ability of lining material significantly, improves working life.

For achieving the above object, the utility model adopts following technological scheme:

Described anchoring net adopts the steel band of Wear Resisting Steel, stainless steel and Common Straight Carbon Steel to make trapezoidal wavy steel band bar through punching press, is fastened into hexagonal shape mutually by the steel band bar then.

Described anchoring net, its each bar steel band is made up of many identical minimum unit steel bars that are stamped to form, the top riveting hole edge of each unit steel bar has two identical rivet holes, and the around side of unit steel bar respectively has outer mud pawl and interior mud pawl, external sludge claw hole and internal sludge claw hole; Its underpart riveting claw edge has the riveting pawl, and the riveting dog clutch of every steel band is connected in the rivet hole of another steel band, and many mutual snappings of steel band are formed the anchoring net.

Described anchoring net respectively is provided with on the left and right mud pawl limit of its unit steel bar inwardly, outwards, and direction is opposite, and two mud pawls that shape is identical all have four mud pawls like this in each hexagonal shaped unit.

Described anchoring net, the shape of its each mud pawl can be circular shapes; Can also be down trapezoidal shape or elliptic arc shape.

Owing to adopt aforesaid technological scheme, the utlity model has following superiority:

Owing to increased the structure of two mud pawls, make it enlarge the area of contact and the anchoring ability of anchoring net and lining material, thereby effectively strengthened the binding ability of lining material and matrix, the generation of the phenomenon that can control heat-resisting, insulation, the easy peeling of anticorrosive coat fully and come off, the reliability and the working life of anchoring mesh liner nexine have been improved, the generation of dangerous accident has improved economic benefit in having avoided producing.

Fig. 2 is an anchoring web frame schematic representation:

As shown in FIG.: mud pawl limit, a 1-left side; The 2-riveting hole edge; The right mud pawl of 3-limit; The 4-riveting claw edge; The outer mud pawl of 5-; Mud pawl in the 6-; The 7-rivet hole; 8-riveting pawl; The 9-external sludge claw hole; The 10-internal sludge claw hole.

Embodiment:

As shown in Fig. 1,2: this anchoring net, adopt the steel band of Wear Resisting Steel, stainless steel and Common Straight Carbon Steel to make trapezoidal wavy steel band bar through punching press, be fastened into hexagonal shape mutually by the steel band bar then; Its each bar steel band is made up of many identical minimum unit steel bars that are stamped to form, the top riveting hole edge (2) of each unit steel bar has the around side of two identical rivet holes (7) unit steel bar outer mud pawl (5) and interior mud pawl (6) respectively to be arranged, external sludge claw hole (9) and internal sludge claw hole (10); Its underpart riveting claw edge (4) has riveting pawl (8), and the riveting dog clutch of every steel band is connected in the rivet hole of another steel band; Respectively be provided with on the left and right mud pawl limit (1) of its unit steel bar, (3) interior, outward direction is opposite, two mud pawls that shape is identical all have four mud pawls like this in each hexagonal shaped unit; The shape of each mud pawl can be a circular shape; Can also be down trapezoidal shape or elliptic arc shape, the thickness of its anchoring net can be made into more than 300 specification from 6mm-50mm.

The anchoring net when it is used to pour into a mould amorphous refractory, can be made needed shape with the anchoring net that assembles earlier, and point is welded in the inwall of matrix, pours into a mould needed refractory material then and gets final product.Can increase the several times in working life like this.And refractory material can not peel off, and the material mouth is unlikely obstruction.
