Rubber plug hole 108 is offered on rubber plug 102, rubber plug 102 can cooperate solid with the prefabricated port 104 of sleeve body 101 It is fixed.

Further, spring 103 is arranged in sleeve body 101.One end of spring 103 is fixed on rubber plug 102, bullet The other end direction grouting port 105 of spring 103.The other end of spring 103 extends substantially to the interposition of entire sleeve body 101 It sets.It is suitable for the reinforcing bar with insertion from the inside center channel that spring 103 is formed, Specific construction process will retouch in detail later It states.

Preferably, the central axes of sleeve body 101 are overlapped with the axis of spring 103, to guarantee the accurate positionin of reinforcing bar, no Understand radially beat.

With reference to Fig. 1, Fig. 4 and Fig. 5, preferably, offering first annular groove 109 in the bottom surface of rubber plug 102.In the first ring The inside of connected in star 109, rubber plug 102 form the first annular fin 110 protruded outward.One end of spring 103 by this first Annular protruding rib 110 is fixed in first annular groove 109.Specifically, first annular groove 109 can accommodate spring 103 One end, first annular fin 110 are equivalent to a buckle, one end of spring 103 are fastened in first annular groove 109.Hold Intelligible, the diameter of one end of spring 103 should be less than the diameter of first annular fin, so that the cooperation of spring 103 is solid It is scheduled in the first annular groove 109 of rubber plug 102.More preferably, first annular fin 110 is wedge shaped, prevents the one of spring 103 End is detached from rubber plug 102 easily.

Preferably, the inside in rubber plug hole 108 forms multiple second annular protruding ribs 111 inwardly protruded out.Work as construction operation When, which can be resisted against the outer surface of reinforcing bar, form sealing effect to prevent cement mortar along rubber plug hole 108 leakages.

Preferably, second annular groove 112 is offered on the top surface of rubber plug 102, to provide appropriate deformation, so that rubber plug 102 is closer with the cooperation of prefabricated port 104 and reinforcing bar.

Preferably, the apical margin 113 of rubber plug 102 is protruded outward to cover the prefabricated port 104 of sleeve body 101.

It can any one of tapered, oval, cylindrical, dolioform or olive shape preferably, spring 103 is whole. With reference to Fig. 3, in an embodiment, 103 global shape of spring is cylindrical.

It closes up preferably, the other end of spring 103 is formed, positioning when reinforcing bar being facilitated to be inserted into.

Preferably, the length of spring 103 in a free state is greater than the diameter length of 8 times of reinforcing bars.

Preferably, the tensile elongation of spring 103 is not more than 10mm.

Preferably, the line footpath a of spring 103 is 1.0mm~8.0mm.

Preferably, the pitch b of spring 103 is 5mm~20mm.

Preferably, the material of spring 103 is carbon spring steel or alloy spring steel.

Fig. 2 is returned back to, a plurality of cyclic rib 114 inwardly protruded out is formed on the inner wall of grout sleeve 100, in adjacent ring Multiple shearing slots 115 are formed between shape rib 114.The aperture of the prefabricated port 104 of grout sleeve 100 is inwardly gradually reduced, so as to Rubber plug can smoothly fill in prefabricated port 104 along the inner wall of prefabricated port 104 when construction, improve construction efficiency.

Preferably, the inner wall of prefabricated port 104 groove 116 annular in shape, enables rubber plug 102 along the ring-type of prefabricated port 104 The inclined-plane of groove 116 smoothly slides into, and installation is facilitated to cooperate.

Preferably, the groove width of multiple shearing slots 115 is identical.It is provided in this way and is conducive to production and processing, improve production efficiency, and Conducive to splice uniform force in grout sleeve 100, the security reliability and durability of the connection of grout sleeve 100 can be promoted.

Preferably, the section of cyclic rib 114 is wedge shaped.The wedge-shaped groove 117 of cyclic rib 114 towards prefabricated port 104 or Grouting port 105.As shown, multiple cyclic ribs 114 close to prefabricated port 104 wedge-shaped groove 117 towards prefabricated end Mouthful 104 sides, multiple cyclic ribs 114 close to grouting port 105 wedge-shaped groove 117 towards grouting port 105.Work as reinforcing bar During tension, multiple shearing slots 115 that multiple tracks cyclic rib 114 is constituted on the inner wall of sleeve body 101 are to grout sleeve 100 Interior slurry plays restrictive to ensure that the vertical connection key node connection reliability between concrete prefabricated element, safety And durability.

Preferably, the aperture of the stock inlet 106 in sleeve body 101 is greater than the aperture of grout outlet 107.Be conducive to grouting set The grouting construction operation of cylinder 100 can improve the grouting passability of stock inlet 106, ensure that 100 inner cavity slip casting of grout sleeve is full Degree, improves slurry compactness.

Fig. 6 shows the usage state diagram of the grout sleeve of the utility model one embodiment.Below with reference to Fig. 6, and tie All attached drawings are closed to introduce the groundwork process of grout sleeve 100.When construction, first rubber plug 102 and spring 103 are assembled, One end of spring 103 is buckled into the first annular groove 109 of rubber plug 102, then by rubber plug 102 and spring 103 by prefabricated port one Side is put into sleeve body 101.Rubber plug 102 is pressed, the inner wall cooperation of rubber plug 102 and prefabricated port 104 is fixed.Then, will It stretches out reinforcing bar 118 to be inserted into corresponding grout sleeve 100, stretches out the rubber plug hole 108 that reinforcing bar 118 enters rubber plug 102, and pass through bullet The central passage of spring 103 and the medium position for protruding into sleeve body 101.It closes up since the other end of spring 103 is equipped with, reinforcing bar 118 stop at closing in position.It stretches out after reinforcing bar 118 is docked with the reinforcing bar 119 in former grout sleeve 100 high strength cement mortar 120 pour into entire grout sleeve 100 by stock inlet 106.When cement mortar 120 is overflowed by grout outlet 107, illustrate cement bonded sand Slurry 120 has filled up the gap in entire sleeve body 101 between reinforcing bar 118,119.After the hardening of cement mortar 120, Two reinforcing bars 118,119 are just securely joined together, to achieve the purpose that two end bars 118,119 of connection, at connecting node Without casting concrete, joint efficiency is higher.In this work progress, when reinforcing bar 118 is inserted by the rubber plug 102 of prefabricated port 104 When entering in sleeve body 101, the central passage of spring 103 is penetrated, under the action of spring 103, enables the substantially position of reinforcing bar 118 Enter in the axial location of sleeve body 101, and cannot radially beat, to promote the locating accuracy of reinforcing bar 118.Together When, spring 103, rubber plug 102 and reinforcing bar 118 form the skeleton in sleeve body 101, play cement in constraint sleeve body 101 The effect of mortar 120 improves the brittleness that cement mortar 120 is destroyed；And can guarantee 100 overall stiffness of grout sleeve, it improves it and holds Carry power and anti-seismic performance.Guarantee durability and the safety of construction work most critical connecting node.

Those skilled in the art can be obvious, can the above exemplary embodiments of the utility model be carry out various modifications and be become Spirit and scope of the type without departing from the utility model.Accordingly, it is intended to which the utility model covering is made to fall in the appended claims And its modifications and variations to the utility model within the scope of equivalent arrangements.
