Abstract

The invention discloses a fully-grouted sleeve for rebar connection. The fully-grouted sleeve comprises a sleeve body with an inner grouting cavity, two rebars are inserted into the sleeve body from two ends of the sleeve body respectively, O-shaped seal rings are hermetically arranged between the rebars and each of two ends of the sleeve body, the inner surface of the sleeve body is provided with inner shear rings, the outer surface of the sleeve body is provided with outer shear rings, the lateral face of one end of the sleeve body is provided with a grouting port, and the lateral face of the other end of the sleeve body is provided with an overflow port. The fully-grouted sleeve for rebar connection has the advantages that an interlocking force between the sleeve and concrete grout is increased, and grout leakage is prevented by the seal rings arranged at two ends of the sleeve; in addition, the fully-grouted sleeve is simple in operation, accurate in positioning and worthy of popularization.

Description

A kind of full grout sleeve of bar connecting
Technical field
The invention belongs to building field, it is specifically related to a kind of full grout sleeve of bar connecting.
Background technology
Traditional bar connecting mode mainly contains colligation overlap joint, is mechanically connected and welding three kinds. But the development along with construction, the requirement of fabrication of reinforcing cage is more and more higher, new requirement cannot complete by tradition reinforcing bar mode of connection, bar connecting can be good at realizing bar connecting as a kind of rebar connector with full grout sleeve, but axially control difficulty when common bar connecting uses with full grout sleeve, locate inaccurate, it is easy to leakage slurry, tension power is poor, can not ensure construction quality.
Summary of the invention
For making up the deficiencies in the prior art, the present invention provides a kind of simple to operate, not easily leaks the full grout sleeve of bar connecting of slurry.
The present invention is achieved through the following technical solutions:
A kind of full grout sleeve of bar connecting, its special character is: comprise sleeve body, described sleeve body inside is grouting cavity, and two reinforcing bars insert in sleeve body from sleeve body two ends respectively, are sealed with O RunddichtringO between sleeve body two ends and reinforcing bar; Being told sleeve body internal surface and be provided with interior shearing ring, outside surface is provided with outer shearing ring; Described sleeve body one end side has grouting mouth, and the other end side has grout outlet.
The full grout sleeve of a kind of bar connecting of the present invention, the outside surface of described grouting mouth and grout outlet is provided with screw thread.
The full grout sleeve of a kind of bar connecting of the present invention, the wall thickness of described sleeve body is 4.8mm, greatly strengthen the tension power of sleeve.
The invention has the beneficial effects as follows: the full grout sleeve of the bar connecting of the present invention is provided with inside and outside shearing ring, enhances the snap-in force between sleeve and grouted aggregate concrete, and sleeve two ends are provided with sealing-ring mortar leakage prevention, and the present invention is simple to operate, and accurate positioning is worthy to be popularized.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
In figure, 1 sleeve body, shearing ring in 2,3 outer shearing rings, 4 reinforcing bars, 5O RunddichtringO, 6 grouting mouths, 7 grout outlets, 8 screw threads.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Accompanying drawing is a kind of embodiment of the present invention. This embodiment comprises sleeve body 1, sleeve body 1 is cylindrical tube, the wall thickness of sleeve body 1 is 4.8mm, this thickness is bigger than ordinary cartridge thickness, can strengthening the tension power of sleeve, described sleeve body 1 inside is grouting cavity, and two reinforcing bars 4 insert in sleeve body 1 from sleeve body 1 two ends respectively, being sealed with O RunddichtringO 5 between sleeve body 1 two ends and reinforcing bar 4, when preventing from being in the milk, concrete spills from port;Being told sleeve body 1 internal surface and be provided with interior shearing ring 2, outside surface is provided with outer shearing ring 3, strengthens the snap-in force between sleeve body 1 and grouted aggregate concrete; Described sleeve body 1 one end side has grouting mouth 6, and the other end side has grout outlet 7, and the outside surface of grouting mouth 6 and grout outlet 7 is provided with screw thread 8, is convenient to grouting.
The present embodiment is when constructing, two reinforcing bars 4 are inserted in sleeve body 1 from sleeve body 1 two ends respectively, it is provided with a circle chimb in the middle of sleeve body 1 internal surface, two end bars 4 can be accurately helped to locate, good seal O RunddichtringO 5, concrete is injected until concrete overflows from grout outlet 7 from grouting mouth 6, now, concrete has been filled in grouting cavity, outer shearing ring 3 outside sleeve body 1 adds sleeve and concrete snap-in force, embodiment adds the length of grouting mouth 6 and grout outlet 7, make more easily to be connected with external Grouting Pipe during slip casting, difficult drop-off.
