Description
Technical field
The present invention relates to the interconnection technique field of works, in particular to a kind of rotation self-clamping type rod piece connector.
Background technique
In engineering construction, regular reinforcement, deformed bar and other rod pieces being fixed on two mounting structures exist
The deviation occurred in allowed band when docking is unavoidable, to adapt to this docking deviation, mostly uses grout sleeve to connect greatly at present
Connect, bellows reserving hole channel grouting connection and using the connection modes such as box, these connection types all exist complicated construction technique,
Can not detect, quality is difficult to ensure, reaches the drawbacks such as the waiting time is longer of intensity, if directly connected using straight screw connection etc.
Mode is connect, then extremely harsh to the positioning of connecting rod and production required precision, the error of half pitch is even more on axis direction
One obstacle that can not go beyond.
Be bolted, being fully connected between rod piece can must be realized using the measure of tightening, to construction space require compared with
Height, and smaller scope of application.
Summary of the invention
In view of the above drawbacks of the prior art, the present invention provides a kind of rod piece mechanical connection for being suitable for multidirectional deviation
Device, especially larger to the error adaptability on center line of the bar direction, purely mechanic connection of the present invention between deviation rod piece are fitted
Answer between two rod pieces longitudinally, laterally and the manufacture deviation of corner all directions, and its tensile and compressive strength with whether be in the milk it is unrelated,
It without waiting for grouting material or cast-in-place concrete setting time, constructs convenient and quick, convenient for detection, acceptance criteria is clear, and quality is steady
It is fixed, securely and reliably.
To achieve the above object, the invention discloses a kind of rotation self-clamping type rod piece connectors, are embedded in spelling for connecting
The rod piece two for filling the rod piece one on component A and being embedded on assembling members B；Comprising at least from card rotary shaft, the first anchoring sleeve
With the second anchoring sleeve.
It is described to include central axis, central axis slant nut and trapezoidal convex block, the first anchoring sleeve packet from card rotary shaft
Containing at least first sleeve, first sleeve head end anchor slab, first sleeve aft end anchor slab and elastomer, second anchoring sleeve
Include the second casing and the second sleeve end anchor slab.

Pipe end anchor slab and the rod piece two removably connect.
Second internal surface of sleeve pipe setting trapezoidal groove and longitudinal chute, it is described on the trapezoidal groove and the central axis
Trapezoidal convex block shape is to matching；Trapezoidal convex block and institute when the central axis is inserted into second casing, on the central axis
Stating the inclined-plane between the trapezoidal groove on the second internal surface of sleeve pipe allows the central axis to rotate automatically, makes trapezoidal on the central axis
Convex block is directed at the longitudinal chute of second casing, so that the central axis be made smoothly to be inserted into second casing.
Preferably, second outside of sleeve is arranged flexible tensile part, outside the flexible tensile part and second casing
Side is fixedly connected or is in close contact.
The flexible tensile part is affected in outside, and second casing is gradually moved to leaving first sleeve direction, works as institute
When stating the trapezoidal groove on the trapezoidal convex block on central axis and second internal surface of sleeve pipe and being laterally aligned to, in the first sleeve
Elastomer holds out against effect so that the central axis reversely rotates, and the trapezoidal convex block on the central axis is embedded in second casing
In trapezoidal groove on inner wall, anchorage effect is formed.
Further technical solution is that first anchoring sleeve includes at least first sleeve, first sleeve head end anchor
Plate, spherical pad, first sleeve aft end anchor slab, first sleeve bolt-nut and elastomer.
The first sleeve bolt-nut and the rod piece one removably connect；The first sleeve head end anchor
Plate, the spherical pad and the first sleeve bolt-nut are successively held out against.
Preferably, with the contact of oblique end face between the central axis slant nut and the first sleeve aft end anchor slab；
The elastomer is set between the first sleeve head end anchor slab and the central axis slant nut.
Preferably, the first sleeve divides head and the tail portion region Liang Ge, the first sleeve head and the first set
Tube head end anchor slab is connected with screw thread pair, and the first sleeve tail portion and the first sleeve aft end anchor slab are connected with screw thread pair
It connects；The second sleeve end anchor slab is connected with the rod piece two with screw thread pair.
The present invention has below beneficial to benefit.
Present invention efficiently solves the mechanical splice problems with multidirectional deviation rod piece in engineering construction field, realize prefabricated
Complete mechanical connection when the rod pieces such as reinforcing bar dock in splicing structure, and guarantee that bonding strength reaches level-one requirement, so that prefabricated
Inspection, inspection and the examination of the rod pieces connector such as reinforcing bar and presstressed reinforcing steel are fully equivalent to ordinary connector in splicing structure.
Connector total length of the present invention is small, and not only material utilization amount substantially reduces, and applicable situation is also more extensive.
Since the invention belongs to the performances of purely mechanic connection, tensile strength, and grouting material need not be waited to reach some condensation by force
Angle value, therefore structure assembly can work continuously, and be truly realized rapid construction.
