Abstract
The utility model relates to a prestressing outer body cable, which is composed of a plurality of steel strands with protective layers and prestressing extruded anchor tools which are positioned at both ends of the steel strands, wherein, cylinder-shaped pressing bodies are combined with the steel strands with protective layers into integration through cold extrusion to form the extruded anchor tools. The external circumference of the cylinder-shaped pressing bodies is provided with screw threads which are provided with clamping nuts, and the spaces between the end heads of the steel strands and the pressing bodies are plugged through choke plugs. The utility model has the advantages of good protective capability, good load capability, small volume, simple structure, convenient construction, and convenient maintenance. The utility model can be widely used for old bridge reformation, continuous beams, arch bridge structure, and a bridge with cantilevered structure.
Description
The utility model relates to a kind of prestressing force external tendon.
In old bridge rebuilding construction, bridge floor is stressed in order to improve, raising intensity, generally will add reinforcing bar and fluid concrete again in the bridge floor ditching, the ground tackle anchoring of reinforcing bar both sides, and this structure is commonly called as rope in the prestressing force body.The rope construction is loaded down with trivial details in this class body.People urgently wish that a kind of barrier propterty is arranged, load-carrying properties are good, easy construction, need not to add the prestressed cable that is embedded in the structure.
The purpose of this utility model is to provide that a kind of load-carrying properties, barrier propterty are good, use, easy to maintenance, prestressing force external tendon that two ends have prestressing force squash type ground tackle.
For reaching above-mentioned purpose, the prestressing force external tendon of the utility model is made of several steel hinge lines that have overcoat and the prestressing force squash type ground tackle that is positioned at the steel hinge line two ends, described prestressing force squash type ground tackle is formed by pressing body and the several steel hinge line extruding that have overcoat, pressing body is a cylindrical shape, cylindrical is threaded, hold-down nut is arranged on it, and plug is blocked the gap between pressing body and the steel hinge line termination.
Owing to adopt said structure, the utlity model has following advantage:
1, barrier propterty, load-carrying properties are good.The utility model adopts the several high strength steel hinge lines that have overcoat as presstressed reinforcing steel, and with this steel hinge line and the cool one that is squeezed into of pressing body, thereby load-carrying properties are good especially.
2, little, simple in structure, the easy construction of volume, be convenient to safeguard.
The prestressing force external tendon of the utility model is connected connector earlier in use with pressing body, carry out stretch-draw with tensioner, when being stretched to designing requirement, fixes with nut again.Owing on the pressing body external screw thread and nut are arranged, be convenient to adjust Suo Lihe and more renew rope, it is very convenient to construct.
Because above-mentioned distinct advantages, the prestressing force external tendon of the utility model is generally promoted the use of, and particularly is used widely in old bridge transformation, continuous beam, arch bridge structure and the construction of suspended wall structure bridge.
Below, the architectural feature to the prestressing force external tendon of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Fig. 1: prestressing force external tendon structural representation.
The A-A diagrammatic sketch of Fig. 2: Fig. 1.
Embodiment
The prestressing force external tendon structure of the utility model as shown in Figure 1, constitute by the steel hinge line 3 of 7 band overcoats 5 and the prestressing force squash type ground tackle that is positioned at steel hinge line 3 two ends thereof, this prestressing force squash type ground tackle is squeezed into one by the steel hinge line 3 of columnar pressing body 4 and 7 band overcoats 5 by the cold extrusion mode, on columnar pressing body 4 cylindricals external screw thread is arranged, clamp nut 2, the gap of plug 1 between pressing body 4 and steel hinge line 3 terminations are arranged on it.
As a kind of conversion of the present utility model, the steel hinge line radical that constitutes the prestressing force external tendon can change with the need, is generally 3 to 15, also can use single steel wire.
