Abstract
The utility model comprises a guide cap, a bearing plate, an extrusion head sealing sleeve component, a bearing anchor plate, a grouting pipe, a connecting screw rod and high-strength, low-looseness and non-bonding steel strands, and is characterized in that a sealing sleeve component is provided on an extrusion head, and two or more anticorrosive anchor heads are arranged on a free style single-pore, multi-anchor heads and anticorrosive tendon. In allusion to the stress concentration and easy ground water erosion of the present tendon anchoring sections, the utility model adopts a new tendon structure and anticorrosive technology and solves the stress concentration of the anchoring section and the anticorrosion of anchor cables.
Description
Technical field:
The utility model relates to a kind of free style multi anchors in single hole anticorrosion type prestress anchorage cable.
Background technology:
At present, the steel strand of tension type prestress anchorage cable anchoring section are exposed, and easily by groundwater erosion, and its anchoring section leading portion is the tensile stress concentration zones, and weak in back segment, easily produces shear failure; The extrusion head of pressure-type prestress anchorage cable anchoring section does not seal, and easily by groundwater erosion, and is the compressive stress concentration zones bottom its anchoring section yet, easily causes the anchoring body pressure break and destroys.
Summary of the invention:
In view of the foregoing, the purpose of this utility model is that a kind of anchoring section stress distribution of design is tending towards uniform anticorrosion type prestress anchorage cable.
Design feature of the present utility model has reached above-mentioned purpose, it is by guiding cap, supporting plate, extrusion head, the carrying anchor slab, Grouting Pipe, connecting screw rod, high-strength underrelaxation non-bending steel cable constitutes, it is characterized in that being pressed into extrusion head with the extruded sleeve cold-extruded after steel strand penetrate sealing shroud, sealing ring is between extrusion head bottom and sealing shroud inner face, sealing cap is threaded with sealing shroud and seals with fluid sealant, sealing shroud, be filled with epoxy resin between sealing cap and the extrusion head, the outstanding cylinder of the extrusion head seal cartridge assembly front end that forms embeds the corresponding aperture on the supporting plate, steel strand pass the corresponding aperture on the carrying anchor slab and are fixed between carrying anchor slab and the supporting plate, constitute the anticorrosion type anchor head, two or more such anchor heads are linked to be an integral body by connecting screw rod.This structure is distributed on a plurality of anchor heads of anchoring section prestressing force, has improved anchoring section stress and has concentrated situation, makes the anchoring section stress distribution be tending towards evenly, is difficult for taking place the anchoring body stress destruction.
Because adopted the structure of the extrusion head seal cartridge assembly of high-strength underrelaxation non-bending steel cable and extrusion head, sealing ring, sealing shroud, sealing cap formation, the utility model can be avoided the erosion of underground water to steel strand, thereby possesses anti-corrosion function.
Description of drawings:
Fig. 1 the utility model structural representation.
Fig. 2 the utility model extrusion head seal cartridge assembly structural representation.
The specific embodiment:
This free style multi anchors in single hole anticorrosion type prestress anchorage cable is made of guiding cap 1, supporting plate 2, extrusion head seal cartridge assembly 3, carrying anchor slab 4, Grouting Pipe 5, connecting screw rod 6, high-strength underrelaxation non-bending steel cable 7.High-strength underrelaxation non-bending steel cable 7 penetrate sealing shroud 9 back and increase the spring that rubs, the extruded sleeve cold-extruded is pressed into extrusion head 13, sealing ring 8 is between extrusion head 13 bottoms and sealing shroud 9 inner faces, seal its interfaces by fluid sealant 11 after sealing cap 12 and the sealing shroud 9 usefulness screw threads for fastening, epoxy resin 10 is filled between sealing shroud 9, sealing cap 12 and the extrusion head 13, constitutes extrusion head seal cartridge assembly 3 thus.Because adopted the structure of extrusion head seal cartridge assembly 3, the utility model can be avoided the erosion of underground water to steel strand.The cylinder that extrusion head seal cartridge assembly 3 is given prominence to by front end embeds the corresponding aperture on the supporting plate 2, steel strand pass the corresponding aperture on the carrying anchor slab 4 and are fixed between carrying anchor slab 4 and the supporting plate 2, carry anchor slab 4, extrusion head seal cartridge assembly 3, supporting plate 2 formation anticorrosion type anchor heads thus, the number of anchor head is according to the decision of anchor cable prestressing force size, and a plurality of such anchor heads connect into as a whole by connecting screw rod 6.The carrying anchor slab 4 of each anchor head and supporting plate 2 are inequality on the number of steel strand hole and screw hole, layout, from at the bottom of the hole outside the hole, the carrying anchor slab 4 of each anchor head and the steel strand hole on the supporting plate 2 increase step by step, are convenient to steel strand on the previous stage anchor head and the steel strand on the anchor head at the corresponding levels and pass through.Carrying anchor slab 4 on each anchor head bears the prestressing force that the steel strand transmission on the anchor head at the corresponding levels comes separately, is distributed on each anchor head thereby make prestressing force be able to the one-level level.
The utility model be if can be used for anchoring engineering, will improve the stress of anchoring section, to bad ground anchoring compliance, anchor cable is anticorrosion and the long-acting anchoring of engineering aspect, bring into play its original effect, have fairly obvious social benefit and economic benefit.
