Abstract
The invention discloses a full-grouting sleeve for connection of construction reinforcing steel bars, and belongs to the technical field of building projects. A reinforcing steel bar axial-limiting guide stop dog is arranged on the inner wall in the middle of a sleeve main body; guide slopes are arranged between the stop dog and the inner wall of the sleeve main body; a positioning bolt is arranged on the sleeve main body at the prefabricated end; the reinforcing steel bar at the prefabricated end is axially and radially fixed through the positioning bolt; the sleeve main body is molded by one-step casting of spheroidal graphite cast iron, so that the production cost is low; the outer surface of the sleeve main body serves as a roughened surface, so as to ensure the anchoring force between the grouting sleeve and the concrete; a plurality of convex hooping ribs are arranged on the inner wall of the grouting sleeve; an identification gap is formed in the port face of the sleeve main body at the field poured end, so as to prevent the situation that the grouting sleeve is installed reversely; a seal ring is arranged inside the port of the sleeve main body at the prefabricated end. When the grouting sleeve disclosed by the invention is in axial butt joint with the reinforcing steel bar, the precise axial control can be automatically realized, and the radial positioning can be automatically realized, so as to ensure the positioning accuracy between the reinforcing steel bar and the grouting sleeve, and meet the requirements on building construction quality.
Description
Technical field
The invention belongs to civil works technical field, particularly relate to the connection of a kind of building iron and use full grout sleeve.
Background technology
At present, in the reinforced concrete buildings of China, for the connection of building iron, what the overwhelming majority adopted is traditional connecting method for reinforcing bars, i.e. strapping, welding and screw thread method.
When adopting strapping and screw thread method, therefore and be not suitable for member reinforcing steel bar and connect than the joint reinforcing bar of comparatively dense when the interstitial position of member reinforcing steel bar is smaller, utilize instrument colligation difficulty large, and construction quality is affected by human factors relatively more serious, skeleton is yielding simultaneously.
When adopting welding, be not suitable for member reinforcing steel bar equally and connect than the joint reinforcing bar of comparatively dense, and solder technology requires high, because the technical level of constructor is uneven, construction quality is affected by human factors more serious, and solder yield is unstable.And welding power consumption is high, is sometimes also subject to execution conditions restriction, causes electricity consumption lack of standardization, unnecessary hidden danger can be brought to construction safety.
Along with the continuous progress of modern building technology, require more and more higher to Construction Quality, traditional connecting method for reinforcing bars has been difficult to adapt to modern architecture construction requirement, in this context, person skilled in field develops a kind of brand-new connecting method for reinforcing bars, namely utilize grout sleeve to connect reinforcing bar, this brand-new rebar connecting technology comes across Japan the earliest, and is generalized to the whole world gradually.
Grout sleeve is as the core members of bar connecting, comprise full grout sleeve and half grout sleeve, half grout sleeve one end adopts with reinforcing bar and is threaded, the other end and reinforcing bar adopt to be in the milk and are connected, but adopt half grout sleeve to carry out bar connecting, there is labour intensity large, and reinforcing bar and sleeve be threaded whether put in place judge not directly perceived, easily be affected by human factors, and workmanship is wayward.And although existing full grout sleeve no longer adopts and is threaded, but reinforcing bar and sleeve carry out axis when docking, cannot realize axially controlling accurately, and not possess radial location function, the positioning precision extreme difference of reinforcing bar and sleeve, is difficult to meet Construction Quality requirement.
Summary of the invention
For prior art Problems existing, the invention provides the connection of a kind of building iron and use full grout sleeve, when reinforcing bar and grout sleeve carry out can automatically realizing when axis is docked axially controlling accurately, and automatically can realize radial location, ensure that the positioning precision between reinforcing bar and grout sleeve, meet Construction Quality requirement.
To achieve these goals, the present invention adopts following technical scheme: a kind of building iron connects uses full grout sleeve, comprise sleeve body, first grouting port and the second grouting port, described sleeve body one end is cast-in-site end, the sleeve body other end is prefabricated end, described first grouting port is arranged on the cast-in-site end of sleeve body, described second grouting port is arranged on the prefabricated end of sleeve body, described first grouting port and the second grouting port are all connected with grouting guiding tube, the middle part inwall of described sleeve body is provided with reinforcing bar axial limiting guide stopper, guiding surface is provided with between described reinforcing bar axial limiting guide stopper and sleeve body inwall.
The quantity of described reinforcing bar axial limiting guide stopper is some, and along the uniform setting of sleeve body inwall circumference.
Sleeve body port and the cast-in-site end bar of the sleeve body port of described prefabricated end and prefabricated end bar, cast-in-site end all adopt matched in clearance.
The sleeve body of described prefabricated end is also provided with positioning bolt hole, in positioning bolt hole, positioning bolt is installed, by positioning bolt axis is carried out to prefabricated end bar and radial direction is fixed.
Described sleeve body adopts ductile iron one-step casting shaping.
In order to ensure the anchored force between full grout sleeve and concrete and grouting material, the inside and outside surface of described sleeve body all adopts rough surface.
