Abstract

The invention discloses a connecting and grouting sleeve for assembled prefabricated member steel bars and a construction method thereof, aims at solving the connection problem of the assembled prefabricated member steel bars and has the advantages of simplicity in construction, low cost, high strength and reliability in connection. The connecting and grouting sleeve comprises a sleeve body, sealing rings and a position-limiting bolt, wherein a grouting hole and an exhaust hole position-limiting bolt are arranged on the sleeve body, a block-like bulge is arranged on the inner wall, and the sealing rings are arranged at the two ends in the sleeve body. When prefabricated members are assembled and constructed, the position-limiting bolt is screwed in, two reserved steel bars of the assembled prefabricated members are inserted into limited positions from the two ends of the sleeve body, the elastic sealing rubber rings are squeezed in, cement-based grout is grouted from the grouting hole, and the two reserved steel bars are connected through the sleeve to form a whole. The connecting and grouting sleeve disclosed by the invention can be used for connecting the various assembled prefabricated member steel bars.

Description

Connection grout sleeve and the job practices thereof of prefabricated member reinforcing steel bar
Technical field
The present invention relates to concrete prefabricated element technical field, exactly it is a kind of connection grout sleeve and job practices thereof of prefabricated member reinforcing steel bar.
Background technology
In traditional cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect, be welded to connect or the method such as compression sleeve mechanical connection more, its work progress is comparatively complicated, and the quality of connection of reinforcing bar is also difficult to guarantee, and must before concreting, completes the connection of reinforcing bar.Key issue is: the reinforcing bar that the connected mode of this reinforcing bar can not be applicable to prefabricated member connects.
Summary of the invention
The object of the invention is exactly that a kind of connection grout sleeve and job practices thereof of prefabricated member reinforcing steel bar are provided for the connection of prefabricated member reinforcing steel bar, and it has, and construction is simple, the feature of dependable performance.
The object of the present invention is achieved like this.Prefabricated member reinforcing steel bar connects grout sleeve and comprises: sleeve body, elastic packing rubber ring and caging bolt.It is characterized in that: the two ends of sleeve body are provided with grout hole and steam vent, grout hole and steam vent inwall are provided with screw thread, and in sleeve body, elastic packing rubber ring is equipped with at two ends, and sleeve body is provided with caging bolt, and sleeve body inwall is provided with block-shaped protrusion.
The job practices that prefabricated member reinforcing steel bar grout sleeve connects, it is characterized in that: prefabricated member is after produce in factory moulding, its reserved steel bar can insert in sleeve body temporarily completely, and temporary fixed with caging bolt, during assembling construction, unclamp caging bolt, take off sleeve body, first two elastic packing rubber rings are enclosed within respectively to reserved steel bar and upper, be screwed into caging bolt, in order to limit reinforcing bar and the reinforcing bar position in sleeve, by the reserved steel bar of two prefabricated members with from the two ends of sleeve body, be inserted to restriction position, clamp-on elastic packing rubber ring, grouting lance is connected with grout hole by screw thread, pour into strength cement-based grouting material, after grouting material setting and harden, reserved steel bar and reserved steel bar are connected in one by sleeve.According to Specific construction environment, the function of grout hole and steam vent can be exchanged, and steam vent is as grout hole, and grout hole is as steam vent.
Advantage of the present invention is: thoroughly solved the connectivity problem of prefabricated member reinforcing steel bar, construction is simple, work progress does not need complicated plant equipment and facility, with low cost, intensity is high, connection is reliable.The grout hole arranging on sleeve body and steam vent, can be when pouring into strength cement-based grouting material, and the air in sleeve body is from the smooth and easy eliminating of steam vent.The block-like protrusions of sleeve body inwall, can make strength cement-based grouting material and reinforcing bar, union body firmly combine, the elastic packing rubber ring at sleeve body two ends has avoided grouting material from sleeve body two ends, to flow out before setting and harden completely, caging bolt can guarantee the correct design attitude of both sides reinforcing bar, can obtain again reliable connection effect.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is that A-A of the present invention is to sectional drawing.
The specific embodiment
Embodiment 1:
Sleeve body 1 of the present invention can be cast and make, and is the smooth demoulding, and the middle part wall thickness of sleeve body 1 can be greater than two ends, so also more meets the regularity of distribution that sleeve body middle part internal force is large, two ends internal force is little.The independent cube of block-shaped protrusion 6 that sleeve lining arranges, guarantees the bond effect between reinforcing bar 7 and 8, grouting material and sleeve body 1, after grouting material setting and harden, two reserved steel bars is connected in one by sleeve.The external diameter of the elastic rubber sealing ring 2 at sleeve body 1 two ends is greater than the internal diameter of sleeve body 1, and it is smaller that the internal diameter of elastic rubber sealing ring 2 is less than the external diameter of reinforcing bar 7 and 8, to guarantee sealing effectiveness.Caging bolt 3 is arranged on sleeve body 1.The grout hole 4 at sleeve body 1 two ends and the function of steam vent 5 can be exchanged, that is: 5 as grout hole, and 4 as steam vent, thus inwall all should be threaded, for being connected with grouting lance.
Embodiment 2:
Job practices of the present invention is as follows.Prefabricated member is after produce in factory moulding, reserved steel bar 7 can insert in sleeve body 1 temporarily completely, and temporary fixed with caging bolt 3, to avoid sleeve, lose, during assembling construction, unclamp caging bolt 3, take off sleeve body 1, first two elastic packing rubber rings 2 are enclosed within respectively on reserved steel bar 7 and 8, be screwed into caging bolt 3, in order to limit reinforcing bar 7 and the position of reinforcing bar 8 in sleeve, the reserved steel bar of two prefabricated members 7 and 8 two ends from sleeve body 1 are inserted to restriction position, clamp-on elastic packing rubber ring 2, grouting lance is connected with grout hole 4 by screw thread, pour into strength cement-based grouting material, during grouting, steam vent 5 is unimpeded, to guarantee the air in sleeve body 1 chamber, discharge smoothly, strength cement-based grouting material is closely knit.After grouting material setting and harden, reserved steel bar 7 and reserved steel bar 8 can be connected in one by sleeve.According to Specific construction environment, the function of grout hole 4 and steam vent 5 can be exchanged, that is: 5 as grout hole, and 4 as steam vent.
