Abstract
A wedge pressure attachment joint for the member bar is characterized in that the joint consists of a connecting sleeve and a wedge pressure ring; wherein, the two ends of the connecting sleeve is roughly in the shape of a cone; the generatrix of the cone can be one of the following lines including an oblique line, a break line, or a parabolic curve; the connecting sleeve is provided with a groove with a radial homogeneous distribution and penetrating the wall thickness along the axis, and provided with gears in the inner wall of the connecting sleeve; a wedge pressure ring is arranged at the outside of the two ends of the connecting sleeve. The wedge pressure attachment joint of the utility model has a better performance than the mother plate in tensile resistance, slip resistance and fatigue resistance, the rigidity, unvaried ductility, and mechanical property. Besides, as the manual operation, the utility model also has the advantage of having low labor strength, high construction efficiency, simple structure, little material consumption, no demanding special processing the connected bar, rapid connecting, reliable connection quality, not only connecting the smooth-faced bar but also connecting the reinforcing steel bar with ribs.
Description
Technical field
The utility model relates to a kind of rod member connector, especially a kind of rebar connector that uses in the construction project that is applicable to.
Technical background
At present, the mechanical connection method to reinforcing bar mainly contains both at home and abroad: taper thread of reinforcing bar connects, and reinforced bar straight thread connects, and the reinforcing bar cold extrusion connects, and reinforcing bar bolt-tooth bar latch connects.Wherein taper thread of reinforcing bar, straight a chain for binding criminals line connection will adopt special equipment that steel bar end is processed into taper thread or straight thread, screw shell that will be complementary and reinforcing bar a chain for binding criminals line termination couple together then, when reinforcing bar is slightly grown, connecting wastes time and energy, need pull more than 70 time with the stubborn termination of spanner could tighten, and also needs special-purpose torque spanner to detect pretightning force at last.The reinforcing bar cold extrusion connects and not to need end reinforced processing, but will use superpressure oil pump and oil pressure pincers in connecting, and waste time and energy, and the material of sleeve consumption is 6 times that are threaded, and only is suitable for reinforcing bar with ribbing and connects, and can not be used for the connection of plain bar.It is to arrange some bolts at an axial line of a steel bushing that reinforcing bar bolt-tooth bar latch connects, become 135 ° of Y-axises to being welded with two tooth bar latches that hardness is arranged on the offside steel bushing inwall of bolt respectively, two reinforcing bars insert in the sleeve, tight a bolt one by one with spanner, twist off until bolt head, so bolt and tooth bar latch in the sleeve are a joint with the reinforcing bar interlock.Though this technology does not need the reinforcing bar preprocessing, easy construction, consumptive material is big, for be threaded more than 10 times, and the tensile property of joint does not reach equicohesive requirement.
Summary of the invention
The purpose of this utility model provides a kind of the need the special processing in rod member termination, and bush material is economized, and only needs easy manual operation, and labour intensity is low, efficient is high, connect reliable rod member wedging connection joint.
The utility model is to be made of adapter sleeve and wedge pressure ring.Two external form of adapter sleeve is roughly tapered, and the bus of two cone can be oblique line, broken line, parabolical any.Adapter sleeve is provided with radially the groove that evenly distribution penetrates wall thickness vertically, and the inwall of adapter sleeve is provided with teeth.The wedge pressure ring places respectively on the outside at adapter sleeve two ends.When need connect rod member, termination and two wedge pressure rings of two rod members are placed the interior outside at adapter sleeve two ends respectively, and push the wedge pressure ring vertically in opposite directions.Under the radial pressure of wedge pressure ring,, adapter sleeve is firmly connected as one with the rod member that is connected because the adapter sleeve inwall is provided with teeth and can wedges the rod member that is connected.
This reality is novel because the teeth interlock rod member of adapter sleeve belongs to surperficial extrusion modling, and the tension of rod member joint, shearing resistance, fatigue resistance and rigidity property are all above mother metal, and ductility is constant, have the favorable mechanical performance.The utility model has also that labour intensity hand-manipulated is low, efficiency of construction is high, simple in structure, consumptive material is few, the rod member of required connection need not specially be processed, and connects quick, quality of connection is reliable, applied widely, not only the smooth rod member of bondable surface also can connect advantages such as reinforcing bar with ribbing.
Description of drawings
Fig. 1 is a contour structures schematic diagram of the present utility model;
Fig. 2 is the structural representation that the utility model is used to connect light round bar spare front and back;
Fig. 3 is the A-A sectional view of Fig. 2.
The specific embodiment
The utility model is made of adapter sleeve 1 and wedge pressure ring 2,3.Two of adapter sleeve is conical, and is provided with the groove 6 that 3 to 4 radially even distributions penetrate wall thickness vertically.Before construction, can there be contact at the middle part of adapter sleeve or two ends, make adapter sleeve still as a whole, so that constructing operation.The teeth of the inwall of adapter sleeve can be zigzag or triangle thread.When need connected rod member, rod member to be connected such as Fig. 2 right side state, 1 pair of rod member of adapter sleeve 4,5 played and contain and the guiding constraint effect.In the work progress, available separate type hand-hydraulic clamping clip places the outside of wedge pressure ring 2,3, pushes manual pump, and clamping clip just moves in opposite directions at axial push wedge pressure ring 2,3.Because the two ends, the outside of adapter sleeve 1 are taper, when pushing wedge pressure ring moves and the radially wedge pressure that produces doubles along with the tangent ratio of its angle of wedge.The determining of adapter sleeve (1) two bullet angle of wedge should guarantee that wedge pressure ring (2,3) can self-locking and can not become flexible.For example, be 5000 kilograms through calculating the power that small-sized hand-operated oil pump produces, if the angle of wedge is 5.7 °, then the wedge pressure of adapter sleeve is 50000 kilograms; When nearly 3 ° of the angle of wedge, the wedge pressure of adapter sleeve can reach 100000 kilograms.Radial compression along with adapter sleeve, adapter sleeve two ends or middle tie point may rupture, because the inside and outside surface of adapter sleeve 1 is treated to have a certain degree of hardness, its inwall teeth can wedge be nipped in the rod member 4,5, thereby make adapter sleeve press and be connected with rod member, the firm wedge of the wedge pressure ring Trinity.Rod member after the connection is shown in the left side state of Fig. 2.
Claims (4)
