Abstract

The invention discloses a precast grouted steel bar connecting sleeve and a construction method thereof. In the traditional cast-in-place concrete structure, steel bars are mainly connected by adopting a mechanical connecting method such as lapping, welding or sleeve extrusion or the like, the construction for connecting the steel bars is complex, and the connection of the steel bars must be completed before the concrete is poured, so the connecting method is not suitable for an assembled construction method for a precast concrete structure. The precast grouted steel bar connecting sleeve comprises a sleeve body (1), two ends of the sleeve body (1) are provided with elastic rubber sealing rings (2), a limiting bolt (3) is arranged in the middle of the interior of the sleeve body (1), two ends of the sleeve body are provided with a grouting hole (4) and an exhaust hole (5) communicated with the interior, and the inner wall of the sleeve body is provided with a conical thread (6). The precast grouted steel bar connecting sleeve is suitable for assembled connection construction of the steel bars.

Description

Prefabricated cover grouting reinforcing steel bar connecting sleeve tube and job practices thereof
Technical field:
The present invention relates to a kind of method of work that is used for the prefabricated cover grouting reinforcing steel bar connecting sleeve tube of reinforcing bar assembling connection.
Background technology:
In traditional cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect, be welded to connect or mechanical connection method such as compression sleeve more, the construction that reinforcing bar connects is comparatively complicated, and must before fluid concrete, finish the connection of reinforcing bar, be not suitable for the assembly construction method of precast concrete.
Summary of the invention:
The purpose of this invention is to provide the method that a kind of prefabricated cover simple to operate, dependable performance is in the milk reinforcing steel bar connecting sleeve tube and utilizes this sleeve to construct.
Above-mentioned purpose realizes by following technical scheme:
Prefabricated cover grouting reinforcing steel bar connecting sleeve tube, its composition comprises: sleeve body, elastic rubber sealing ring is equipped with at described sleeve body two ends, described sleeve body bosom is provided with caging bolt, described sleeve body two ends are provided with grout hole and the steam vent with internal communication, and described sleeve body inwall is a tapered thread.
Described prefabricated cover grouting reinforcing steel bar connecting sleeve tube, the hoop thickness of described elastic rubber sealing ring is bigger than the slit between sleeve body and the reinforcing bar, and the internal diameter of elastic rubber sealing ring is littler than reinforcing bar external diameter, and described grout hole and steam vent hole wall are provided with one section screw thread.
A kind of job practices of utilizing above-mentioned prefabricated cover grouting reinforcing steel bar connecting sleeve tube, described precast unit is after produce in factory, sleeve is inserted in its reserved steel bar end temporarily fully, and available caging bolt is temporary fixed to avoid something lost to fall, when another precast unit through hoisting and locating, its reserved steel bar corresponding with it near the time, sleeve is moved to the reinforcing bar junction, make sleeve be inserted in two coaxial reinforcing bars respectively to projected depth, be screwed into caging bolt, clamp-on elastic rubber sealing ring, connect grout pipe and pour into the cement-based grout material by grout hole, and guarantee to be in the milk closely knit by the steam vent exhaust, behind the grouting material setting and harden, reserved steel bar and reserved steel bar are connected in one by sleeve.
Beneficial effect of the present invention:
1. the present invention is provided with grout hole and the steam vent with sleeve inner UNICOM, so that pour into the cement-based grout material by grout hole, steam vent makes filling process more smooth and easy.Grout hole and steam vent hole wall are provided with one section screw thread, combine closely with it when being convenient to Grouting Pipe and being screwed into.The effect of elastic rubber sealing ring is exactly to avoid grouting to expect to trickle metal sleeve before setting and harden.
2. bosom of the present invention position is provided with 1 caging bolt, can limit the both sides reinforcing bar when caging bolt is screwed into and be inserted in projected depth.Space between caging bolt and the sleeve lining can make the grouting material closely knit by being in the milk smoothly, therefore promptly can fully guarantee the correct design position of reinforcing bar, can obtain reliable connection effect again.
3. the present invention is for the bonding of reinforcing steel bar, sleeve lining is designed to comparatively thick screw thread form, simultaneously in order when sleeve is cast, to make inner mold deviate from smoothly, this screw thread design is a tapered thread, be convenient to the demoulding of inner mold and back-out, in addition, tapered thread makes that sleeve middle part wall thickness is thick slightly, two ends are thin slightly, also met the principle that adhesion stress is transmitted between reinforcing bar and the sleeve, promptly met the sleeve middle part because of the stressed big thicker material of needs, and two ends are because of the adhesion stress transmission, and sleeve internal force reduces gradually and do not need thicker material, saving of labor, material-saving.
4. the present invention adopts the slit between elastic rubber sealing ring seal sleeve and the reinforcing bar, metal sleeve trickles before the slurry setting and harden when having avoided the grouting material, this elastic rubber sealing ring hoop thickness is bigger slightly than the slit between sleeve and the reinforcing bar, and the internal diameter of elastic rubber sealing ring is slightly littler than reinforcing bar external diameter, like this when elastic rubber sealing ring is clamp-oned slit between reinforcing bar and the sleeve, because of elastic rubber sealing ring has better elastic, can fit with sleeve lining and reinforcing bar outer wall respectively fully in its outside and inboard, then the slit between seal sleeve and the reinforcing bar fully.
5. the present invention is simple to operate, is inserted in and simple filling process behind just manual pre-buried by factory, the on-site hoisting, and work progress does not need complicated mechanical equipment and facility, does not need power consumption yet.
