Description
Technical field
The utility model is related to a kind of reinforcing steel bar connecting sleeve tubes, and in particular to connect to a kind of anti-skidding straight thread with cramping body
Female connector cylinder.
Background technology
In building trade, traditional bar connecting mode includes overlap joint connection and is welded to connect.With building trade
It rapidly develops, overlap joint connection has not been suitable for the reinforcing bar of big specification, and being welded to connect also has many shortcomings, such as by steel
Situations such as solderability is poor, power supply is unstable, welder is horizontal poor, the duration is tight, capacitance is inadequate caused by muscle material is unstable,
Welding quality is set to cannot be guaranteed.Steel concrete supporting is a new reinforcing steel bar connection type, is referred to as after overlap joint, welding
" third generation splice ", have strength of joint higher than parent material of reinforcement rebar, connection speed is fast, it is pollution-free, save steel etc. significantly
Advantage.
Currently used reinforced bar mechanical connector is mainly extrusion socket joint connector, taper thread jointing and straight spiral shell
Line jointing.Extrusion socket joint connector is so that branch sleeve plastic deformation is closely engaged shape with Ribbed Bar by extruding force
At connector, be widely used in architectural engineering so far from earlier 1990s in China.Taper thread jointing
It is that the connector to be formed is engaged by the special tapered thread of steel bar end and connector tapered thread, since it is with speed of application
Soon, connector feature at low cost has also obtained large range of promote the use of since earlier 1990s promote.But
Since its quality is not sufficiently stable, gradually replaced by straight thread joint.Straight thread joint is reliable and stable, bonding strength
Height can compare favourably with extrusion socket joint connector, and have the characteristics that taper thread joint is easy for construction, fireballing again, therefore,
The appearance of straight thread joint technique brings qualitative leap to rebar connecting technology.
In the installation process of straight thread joint, need the tightening tools such as pipe wrench being sleeved on branch sleeve, but due to
The surface of branch sleeve is complete circular arc, and pipe wrench is caused to be easy to skid.In the bar connecting of certain high intensity, straight spiral shell
The quality of line jointing is still weak.
Utility model content
The utility model provides a kind of anti-skidding straight thread connecting sleeve with cramping body, to solve existing straight thread
Jointing easily skids, connects the defects of not secured enough, improves the applicability of straight thread joint.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of anti-skidding straight thread connecting sleeve with cramping body, including endoporus set threaded connecting sleeve, connector sleeve
The cross section of pipe is that there are two the ellipses of parallel cut surface for tool；The arc surface of connecting sleeve is equipped with multiple and its axis parallel
Groove；The both ends of connecting sleeve are respectively equipped with circumferential outwardly extending spacing ring；The both ends of connecting sleeve are additionally provided with axially outward
The cylindrical shape cramping body of extension, cramping body are equipped with spiral straight slot.
According to said program, the left and right side of the connecting sleeve is respectively equipped with a countersunk head threaded hole, countersunk head screw thread
Dormant bolt is equipped in hole.
According to said program, the more ribs perpendicular to its axle center are equipped in the cramping body.
Compared with prior art, the utility model has the beneficial effects that：By straight thread joint and it is press-connected connector
It is grouped together, makes it have more reliable connection performance；Connecting sleeve, which is equipped with groove, makes its skid resistance be improved；To
The comprehensive performance for improving the utility model makes its applicability be improved.
Description of the drawings
Fig. 1 is the cutting structural schematic diagram of the utility model；
Fig. 2 is the A-A of Fig. 1 to cut-away illustration；
Fig. 3 is the left view of Fig. 1.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, the paraphrase of each label in figure
For：1- connecting sleeves, 2- cramping bodies, 3- spacing rings, 4- ribs, 5- countersunk head threaded holes, 6- dormant bolts.
The utility model includes that endoporus sets threaded connecting sleeve 1, and the cross section of connecting sleeve 1 is that there are two parallel for tool
The ellipse of section.The tightening tools such as pipe wrench are stuck on two parallel cut surfaces so that pipe wrench has focusing surface, will avoid skidding feelings
The generation of condition.The arc surface of connecting sleeve 1 is equipped with multiple grooves with its axis parallel so that its skid resistance is obtained into one
Step improves, and when pipe wrench is not easy to block parallel cut surface, may be stuck on arc surface with groove and carries out tightening operation.Connecting sleeve
1 both ends are respectively equipped with circumferential outwardly extending spacing ring 3 so that pipe wrench will not skid off connecting sleeve 1 in an axial direction, it is ensured that operation
Security and stability.The both ends of connecting sleeve 1 are additionally provided with the axially outwardly extending cylindrical shape cramping body 2, and cramping body 2 is equipped with two
Item opposition spirality groove in order to cramping body 2 plastic deformation.
In use, the end of two sections of reinforcing bars to be connected is processed screw thread and is navigated on same axle center, in joint
It is put into the utility model, the parallel cut surface of branch sleeve 1 or arc surface with groove are blocked by pipe wrench, reverse the utility model
Thus by two sections of bar connectings to together.To further ensure that the stability of connection, two sections of bar connectings in place after, by connector sleeve
The cramping body 2 at 1 both ends of cylinder squeezes, and the surface of reinforcing bar is clung to after so that it is plastically deformed, so as to form connector is press-connected.Folder
Frictional force between reinforcing bar will be further increased in the multiple ribs 4 for holding its vertical axle center being arranged in body 2, and reinforcing bar is made to be more difficult to take off
From the utility model.
Further, the left and right side of connecting sleeve 1 is respectively equipped with a countersunk head threaded hole 5, in countersunk head threaded hole 5
It is equipped with dormant bolt 6.The dormant bolt 6 in left side fixes the reinforcing bar in left side, and the dormant bolt 6 on right side fixes the reinforcing bar on right side.
Dormant bolt 6 further ensure that reinforcing bar is difficult to be detached from the utility model so that the reliability of the utility model obtain into
One step improves.
