Abstract
The utility model provides a moveable coupler, comprising a shaft sealing 3, and a column cylindrical connecting body 2, a squeezing sleeve I (8), a squeezing sleeve II(4), and a bearing plate 5 fixed in the shaft sealing ordinally, and a spring shim 7 arranged between the cylindrical connecting body and the bearing plate. Through holes with different hole diameters at both ends are arranged in the cylindrical connecting body, and internal threads are arranged in the holes. The squeezing sleeve I anchored with a non-agglutinate anchor cable body 9 at one end of the hole is connected with one end of the cylindrical connecting body 2 by the screw thread. The squeezing sleeve II anchored with a non-agglutinate anchor cable body 6 at the other end of the hole is connected with the other end of the cylindrical connecting body 2. The shaft sealing 3 is connected with the bearing plate 5 by the screw thread, and the cylindrical connecting body can slide in the space formed by the connecting body, the shaft sealing, the bearing plate and the squeezing sleeve II. The squeezing sleeve can fixedly connect two segments or more than two segments non-agglutinate anchor cables into an integral non-agglutinate anchor cable body, has the function of mobile anchorage, and can serve as a coupler connecting the two pre-stressing tendons.
Description
Technical field:
The utility model relates to a kind of presstressed reinforcing steel anchoring coupling arrangement, the parts of the monolithic prestressing force finished product anchor cable that particularly a kind of ground anchorage is used.
Background technology:
In current prestress engineering practice, various couplings are all adopted in the connection of presstressed reinforcing steel, but these couplings generally are applicable to ground or the used presstressed reinforcing steel of bridge engineering; And in geotechnical anchor engineering, for solving the endurance issues of prestress anchorage cable, beginning application continuum anchor cable, for adopting the non-bonded anchorage cable body is that the prestressing force finished product anchor cable of cable body material is for the integrated anchor cable, how to solve anchoring section in it multistage anchoring, improve in anchoring section bearing capacity and how the anchor cable more than two sections or two sections is connected into the special-purpose articulation issues that a whole non-bonded anchorage cable body all needs to solve the ground prestress anchorage cable.
The technical problems to be solved in the utility model is: characteristic how to utilize the multistage anchoring of anchoring section in the prestress anchorage cable, to be connected into a whole non-bonded anchorage cable body by the non-bonded anchorage cable more than two sections or two sections, and can disperse to reduce the problem of the peak stress of anchoring section in the anchor cable significantly by carrying masterpiece multistage pressure, and provide a kind of and not only the non-bonded anchorage cable more than two sections or two sections can be connected into a whole piece cable body, but also can divide what anchoring and share the portable coupling of a part of anchoring pressure.
The technical scheme that solves its above-mentioned technical problem is: a kind of portable coupling, reach the cylindrical connected body that is contained in successively in the sealing drum by sealing drum, extruded sleeve I, extruded sleeve II, bearing plate, spring shim between cylindrical connected body and bearing plate constitutes, have the through hole that the aperture, two ends has nothing in common with each other in the columniform connected body, internal thread is arranged in the hole, being positioned at an end anchoring has the extruded sleeve I of non-bonded anchorage cable cable body to connect with cylindrical connected body one end by screw thread, being positioned at other end anchoring has the extruded sleeve II of non-bonded anchorage cable cable body to connect with the cylindrical connected body other end by screw thread, sealing drum is connected with bearing plate by screw thread, cylindrical connected body can the spring shim place by connected body, sealing drum, bearing plate, slide in the space that extruded sleeve II forms.
The portable coupling of the utility model, both can a whole non-bonded anchorage cable body will be connected into by the non-bonded anchorage cable more than two sections or two sections, play multistage carrying again, the effect of portable anchoring, anchoring section in the anchor cable can be made multistage bearing structure, 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; In addition, the portable coupling of the utility model can also be as the coupling that connects two use for tendon.
Compare with traditional coupling, the portable connecting appliance of the utility model has following advantage:
1, move carrying, bearing capacity and presstressed reinforcing steel elongation all have adjustability.
2, the connection radial dimension minimum between the presstressed reinforcing steel can reduce the size of prestressed concrete equivalent-load structure.
3, adopt advanced monolithic extruded technology, its connection is more reliable than conventional couplings, easier.
4, globality is better than traditional coupling, thereby whole antiseptic property is better.
5, several portable couplings use that connects together can be played multistage anchoring, the effect of classification carrying.
6, can carry out the connection of presstressed reinforcing steel according to the job site needs, play coupling.
