Description
The utility model is a kind of high-strength suspension device of anti-corrosion that is used for engineerings such as underground passage, tunnel, bank protection, pit foundation, dam.
The bolt support overwhelming majority is the rock mass that is used for containing heterogeneity, particularly underworkings, rock mass in tunnel contain the trickle of soda acid composition in various degree, add that there was dampness in the air, metallic rod body is for a long time under this severe environmental conditions, make the body of rod surface oxidation reaction take place and corrosion, cause body of rod surface course pull-up to fall, reduce the due suspention bearing value of the body of rod, shortened application life.According to statistics, the average 0.2-1.2mm/ of metallic steel body corrosion rate that uses under the mine.The general diameter of the metal anchors body of rod that present mine uses is Φ 14-Φ 20mm, length of service 5-8.Because corrosion causes the tunnel in bad repair, has influenced mine normal production.Particularly service year limit for length or as the type selecting of permanent openings supporting has to adopt traditional rock to cut arch or the supporting of concrete grid, has strengthened cost of production.Annual industrial equipment of China and equipment reach more than 10,000,000,000 because of corrosion causes economic loss, the economic loss of the U.S., Germany, this class of the Soviet Union also reaches 4%, 3%, 2% of gross national product respectively, because the energy and material that corrosion causes consumes the common concern that surprising numeral has caused domestic and international Machine Design and machine-building department, investigation of materials and production unit, increasing personage recognizes exploitation new material, new technology, new product, and progressively replacing the simple metal material with composite materials becomes a kind of new trend.
The purpose of this utility model provides a kind of can work under adverse circumstances, have the High strength bolt of anti-corrosion function, long service life.
The technical solution of the utility model is as follows: be enclosed with antirust coat around anchor rod body, the material of antirust coat is epoxy resin, mylar, additive, fiber (silk or cloth).When making, these several raw material Hybrid Heating are become glue, through impregnation of fibers silk cloth, twine then and suppress or spray on the body of rod of having made, form antirust coat.Antirust coat has the characteristic with the steel part good combination, its tensile strength height, and the acid and alkali-resistance corrosion is good, and it is in light weight, and ageing resistace is strong.The anchor rod body that is provided with antirust coat improves 5-6 doubly than the anchor pole of common iron application life.Add a certain proportion of fire retardant in addition in antirust coat, the body of rod has fire-retardant and antistatic property meets the down-hole instructions for use fully.In order to prevent that anchor pole from stretching out the outer part of rock and accomplishing anti-corrosion equally, the material of pallet is identical with antirust coat on the body of rod.
Concrete manufacture craft is as follows:
The glue proportioning-→ glue soak multiple cloth-→ body of rod twines
Metallic rod body, baffle plate, the pallet rust cleaning-→ the multiple cloth of baffle plate supporting plate-→ mould and die preheating-→ heat-→ cooling and demolding-→ the correction size-→ finished product.
Anti-corrosion strengthens the anchor pole manufacture craft in two steps: (1) antirust coat raw material production technology: at first epoxy resin is heated to 30 ℃, add mylar then, additive continues to heat 80 ℃, making it to be dissolved as mixed glue solution sticks with paste, be coated in equably after the cooling and cut out good fibre cloth, and cover film up and down, multiviscosisty was used after 7 days.(2) anti-corrosion anchor pole compression moulding technology: will twine reinforcing bar or the steel strand (steel core) of wrapping up in bag layer by layer, put the matched moulds that pressurizes to 30-40 ℃ the mould of heating in advance, continue to be warming up to 100-120 ℃ and insulation, the die sinking of cooling back can realize the purpose of anti-corrosion enhancing.The control temperature is divided three phases, and preferred temperature is 30-80-120 ℃.
In order to guarantee the integraty of the body of rod and tube connector, adopt rigid connection between the two, can cast, section pressure, welding, bonding etc.Behind the nut of screwing on by top tray, again antirust sleeve is loaded onto in addition.The body of rod itself is made by single steel bar or many steel strands, how many anchoring terminations can be made into herringbone according to what composition body of rod steel twisted, plum blossom umbrella shape or O shape etc., and one comes fully to stir when mounted the anchoring agent, two can increase the contact area with the anchoring agent, increase anchored force.In addition, on the body of rod, be with a movably baffle plate, by the length of trip bolt adjustment anchored end, to adapt to different anchoring occasions.The section shape of the body of rod can be circular, also can be Long Circle, triangle, polygon, also can be made into various abnormity as required.
The utlity model has following advantage:
1, corrosion-resistant property is good, long service life.Compare application life with the present simple metal body of rod and can improve more than 5 times.
2, intensity height, supporting capacity is big.Be enhanced about more than once than using the same diameter body of rod to compare supporting capacity at present.
3, applicability is strong, and can be used for roadway, tunnel, dam, anti-base, bank protection supporting etc. needs in the field of supporting, can use in the environment that contains the soda acid composition especially.
4, novel structure, compactness, in light weight, easy to use.
5, remarkable economic efficiency and social benefit are arranged.
