Abstract
The utility model provides a moveable extrusion sheath that relates to a prestressing tendon anchorage carrying device, comprising a cylindrical shaft sealing 6, a columnar sliding extrusion sheath 3 and a spring shim 5 ordinally arranged in the cylindrical shaft sealing 6, and a circular sealing plate 2 and a bearing plate 4 arranged on both ends of the shaft sealing. The spring shim 5 is arranged between the sliding extrusion sheath 3 and the bearing plate 4, and the shaft sealing, the sealing plate 2 and the bearing plate 4 are welded or connected by screw, and the circular sealing plate 2, the columnar sliding extrusion sheath 3 and the bearing plate 4 are all provided with concentric and coaxial circular through holes for the passing of the non agglutinate anchor cable body. The extrusion sheath 3 of the anchorage non agglutinate anchor cable body can slide in the space which the spring shim 5 is in formed by the extrusion sheath, the shaft sealing and the bearing plate. The extrusion sheath not only can load and support moveably, but also can form distributed anchor cable body by sectionally anchored the integration of the anchor cable and the dispersing the load-supporting force as multistage press decreases greatly the anchorage segmental peak stress of the anchor cable.
Description
Technical field:
The utility model relates to a kind of presstressed reinforcing steel anchoring bogey, particularly a kind of portable extruded sleeve.
Background technology:
In current prestress engineering practice, particularly in the geotechnical anchor engineering, for solving the endurance issues of prestress anchorage cable, integrated anchor cable begins to use, for adopting the non-bonded anchorage cable body is the prestressing force finished product anchor cable of cable body material, the bearing capacity of anchoring section all needs a kind of portable anchor device that is applicable to anchoring section anchoring in the integrated finished product anchor cable of prestressing force in the multistage anchoring of anchoring section in solving, the raising, and does not also have at present.
Summary of the invention:
The technical problems to be solved in the utility model is: a kind of portable extruded sleeve that is applicable to that the anchoring section anchoring is used in the integrated finished product anchor cable of prestressing force is provided, the both removable carrying of this extruded sleeve---will carry the masterpiece multistage pressure and disperse, can reduce the peak stress of anchoring section in the anchor cable significantly, can be used for again integrated anchor cable classification anchoring is formed distributed anchor cable body.
The scheme that solves its above-mentioned technical problem is: a kind of portable extruded sleeve, it is characterized in that: this extruded sleeve is by columnar sealing drum, be contained in the cylindrical slip extruded sleeve in the columnar sealing drum successively, spring shim and lay respectively at the sealing plate of the circle at sealing drum two ends, bearing plate is formed, spring shim is between slip extruded sleeve and bearing plate, sealing drum and sealing plate, between the bearing plate by the welding or be threaded, circular sealing plate, all have the manhole of the concentric co-axial of passing on cylindrical slip extruded sleeve and the bearing plate for the non-bonded anchorage cable cable body, the extruded sleeve of anchoring non-bonded anchorage cable cable body can the spring shim place by extruded sleeve, sealing drum, slide in the space that bearing plate forms.
The portable extruded sleeve of the utility model is with a branch of whole non-bonded anchorage cable body segmentation extruding, forms portable extruded sleeve, both can play multistage carrying, the effect of portable anchoring; Anchoring section in the anchor cable can be made multistage bearing structure again, utilize the mechanism of action of pressure dispersion anchoring, reduce the peak stress of anchoring section in the anchor cable significantly, improve the globality and the total bearing capacity of anchor cable.
Because adopt said structure, the portable extruded sleeve of the utility model is compared with traditional extruded sleeve,
Have following advantage:
1, removable carrying, bearing capacity and presstressed reinforcing steel elongation all have adjustability.Because columnar sealing plate, cylindrical slip extruded sleeve and bearing plate all have the manhole of the concentric co-axial of passing for the non-bonded anchorage cable cable body in the utility model device, the extruded sleeve of anchoring non-bonded anchorage cable cable body can slide in the space that is formed by extruded sleeve, sealing drum, spring shim, bearing plate, anchor cable body, thereby, removable carrying, bearing capacity and presstressed reinforcing steel elongation all have adjustability.
2, several portable extruded sleeves use with the anchor cable body, can play multistage anchoring, the effect of classification carrying.
3, can be single or many presstressed reinforcing steels extruding carryings, adopt advanced monolithic extruded technology, higher than conventional extruded cover bearing capacity.
3, globality packages than traditional extruding, thereby whole antiseptic property is better.
4, simple in structure, can improve the overall security of anchor cable.

The specific embodiment:
Embodiment:
A kind of portable extruded sleeve, by columnar sealing drum 6, be contained in the cylindrical slip extruded sleeve 3 in the columnar sealing drum 6 successively, spring shim 5 and lay respectively at the sealing plate 2 of the circle at sealing drum 6 two ends, bearing plate 4 is formed, spring shim 5 is between slip extruded sleeve 3 and bearing plate 4, sealing drum 6 and sealing plate 2, between the bearing plate 4 by the welding or be threaded, circular sealing plate 2, all have the manhole of the concentric co-axial of passing on cylindrical slip extruded sleeve 3 and the bearing plate 4 for non-bonded anchorage cable cable body 1, the extruded sleeve 3 of anchoring non-bonded anchorage cable cable body 1 can spring shim 5 places by extruded sleeve 3, sealing drum 6, slide in the space that bearing plate 4 forms.
