Description
Technical field
The utility model relates to a kind of at field structural members such as building, bridge and prestressing force ground, particularly a kind of connector for connecting high-strength screw-thread steel muscle or rod iron.
Background technology
In fields such as building, bridge and prestressing force ground, widely apply high-strength screw-thread steel muscle or rod iron, what the spreading of high-strength screw-thread steel muscle or rod iron generally adopted is the connector spreading.
The connector service load level of general high-strength screw-thread steel muscle or rod iron is higher, two high-strength screw-thread steel muscle that must guarantee to be connected or the reliable connecting length between rod iron and the connector; Because being subjected to the impact of place, mounting process and applying working condition, connector often gets loose phenomenon, cause the workload that needs the multiple reversal reinspection to look into and done over again, increased installation and checked in the actual use, also increased the security risk that engineering is used, reliability and the application life of having reduced anchor structure; Therefore, the growth requirement that the high-strength screw-thread steel muscle of commonly using at present or rod iron connector can not satisfy prestress engineering.
In engineering is used, high-strength screw-thread steel muscle or rod iron connector 6 commonly used also uses locking nut 5 locking at present, as shown in Figure 5, but locking nut 5 is rotation stopping function not, high-strength screw-thread steel muscle or rod iron 11,12 still can loose with locking nut integral body, connector can not guarantee the reliability that high-strength screw-thread steel muscle or rod iron connect, entail dangers to engineering safety.
Summary of the invention
The purpose of this utility model is to provide a kind of connector with the spline nut, by the spline nut that is installed on high-strength screw-thread steel muscle or the rod iron connector body is positioned; Can effectively improve the connection reliability of high-strength screw-thread steel muscle or rod iron by the connector of mounting strap spline nut, reduce the generation that the engineering prestress anchoraging lost efficacy, the problems referred to above that exist to solve prior art.
The technical scheme that addresses the above problem is: a kind of connector with the spline nut, comprise connector body and the spline nut that is installed in the connector body two ends, the two ends of described connector body are Double-conical-surface, being positioned at first conical surface of connector body termination and the angle α of second conical surface is 0 ~ 10o, the spline key that annular protrusion is arranged in the end of second conical surface, the male cone (strobilus masculinus) of turn key till first conical surface, the endoporus of connector body has the continuous full thread that is complementary with high-strength screw-thread steel muscle or rod iron, described spline nut is not nut of the two halves Kazakhstan of splitting, the spline nut inner hole has the screw thread that is complementary with high-strength screw-thread steel muscle or rod iron, one end of spline nut is with the detent that is complementary with inclined-plane, connector body termination and spline key, every one side of something is breathed out otic placode and the bolt hole that erection bolt is arranged on the nut not, and two one side of something breathe out not that nut is connected by bolt.
Its further technical scheme is: on the described connector body spline key of annular protrusion to be shaped as class trapezoidal.
Its further technical scheme be: an end of described spline nut with the groove that is complementary with inclined-plane, connector body termination and spline key be by the spline nut inner conical surface I that is positioned at spline nut end holes inboard and be positioned at the spline nut inner conical surface II of spline nut end holes inboard and the annular pair inner conical surface detents that annular obtuse angle groove forms that annular obtuse angle groove shapes is the class trapezoidal groove that matches with the shape of spline key of annular protrusion on the connector body.
The spline nut external diameter of described connector equates with the connector body external diameter.
Owing to take said structure, a kind of connector with the spline nut of the utility model has following beneficial effect:
With the connector of spline nut by the double-locking to high-strength screw-thread steel muscle or rod iron and connector body, realized location and spline that connector is installed, can prevent effectively that connector from getting loose, be conducive to guarantee the reliability of high-strength screw-thread steel muscle or rod iron spreading:
The connector with the spline nut of the utility model positions connector body by the spline nut that is installed on high-strength screw-thread steel muscle or the rod iron, the spline nut is in the locking screw thread reinforcing bar, the spline nut is also held connector body tightly, by the double-locking to high-strength screw-thread steel muscle or rod iron and connector body, location and spline that connector body is installed have been realized like this; Connector Effective Raise by the mounting strap rotation stop device connection reliability of high-strength screw-thread steel muscle or rod iron, reduce the generation that the engineering prestress anchoraging lost efficacy.
2. the trapezoidal spline key of the class of the utility model connector body end annular protrusion has increased the sectional area of connector body, effectively reduces the service load stress level of spline key, the axial installation of convenience and spline nut; And an end of spline nut with the groove that is complementary with inclined-plane, connector body termination and spline key, strengthened the reliability that spline connects, make with can not mutually rotating between the connector of spline nut and high-strength screw-thread steel muscle or the rod iron, effectively guaranteed the connecting length of connector and high-strength screw-thread steel muscle or rod iron, be conducive to raising and apply prestressed reliability and validity.
3. can be installed on the optional position of high-strength screw-thread steel muscle or rod iron with the connector of spline nut, make things convenient for site operation.
4. its method of attachment is easy, and it is compact that high-strength screw-thread steel muscle or rod iron are connected, and greatly saves installing space, effectively reduces the labour intensity of installation, improves installation effectiveness:
Because the connector body of the technical program is the elongated continuous full thread of equal strength design, the connector that is different from other need to be installed ability connecting reinforcement or rod iron with positive/negative thread, during installation, this connector body is an end that all screws first at indented bars to be connected or rod iron, oppositely screw again connector body, the end face that another root is needed the indented bars of spreading or rod iron with screwed the indented bars of connector body or the end face of rod iron and be close at same axis, oppositely screw connector body can be finished connector body to marker location installation; Secondly, the spline nut is Ha Fushi, and it installs the installing space that does not take indented bars or rod iron and connector, and it is compact that reinforcing bar is connected.
