Abstract
The utility model discloses a flask-shaped grouting rebar connecting sleeve, which is characterized in that: a sleeve (1) is provided with openings at both ends and is matched with a first elastic rubber sealing ring (5) and a second elastic rubber sealing ring (9), and convex ribs (2) are arranged on the inner wall of the sleeve (1); limit lug bosses (3) are arranged in the middle of the inside of the sleeve (1), and the two ends of the sleeve (1) are provided with a grouting hole (6) and a grout outlet (8); and the thick caliber end of the sleeve (1) is provided with the first elastic rubber sealing ring (5), and the narrow caliber end of the sleeve (1) is provided with the second elastic rubber sealing ring (9). The utility model is used for the assembly connection of rebar.
Description
Technical field:
The utility model relates to a kind of ampuliform slip casting sleeve that the reinforcing bar assembling connects that is used for.
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 manner such as compression sleeve more, the construction of these several connected modes is comparatively complicated, and must before fluid concrete, finish the reinforcing bar connection, be not suitable for the fabricated construction of precast concrete.
Summary of the invention:
The purpose of this utility model provides a kind of simple to operate, the ampuliform slip casting sleeve of dependable performance.
The utility model is to realize in the following manner:
Ampuliform slip casting sleeve, its composition comprises: the sleeve of both ends open (1) is furnished with first elastic rubber sealing ring (5) and second elastic rubber sealing ring (9), is applicable to the fabricated construction requirement fully.It is ampuliform hollow that sleeve (1) is designed to inwall, and inwall have the projection rib (2), increased the anchored force between reinforcing bar, grout material and the sleeve, improved anti-seismic performance.Described sleeve (1) bosom is provided with spacing preiection (3), described sleeve (1) two ends are provided with injected hole (6) and the slurry outlet (8) with internal communication, the thick bore end of described sleeve (1) is provided with first elastic rubber sealing ring (5), described sleeve (1) narrow orifice is directly held and is provided with second elastic rubber sealing ring (9), the thick bore end of described sleeve (1) is assembling reinforcing bar (4) insertion end, described sleeve
(1) narrow orifice is directly held and is precast reinforced (7) insertion end.
The course of work of the present utility model:
1, pre-buried: by second elastic rubber sealing ring (9) location, form precast reinforcedly with precast reinforced (7), factory uses precast reinforced reservation injected hole (6) and slurry outlet (8) position, by pre-buried making assembly concrete member.
2, site operation: the job site is by lifting, make the sleeve (1) of prefabricated units hold the assembling reinforcing bar (7) that is inserted in prefabricated units for thick mouthful, between sleeve (1) and the assembling reinforcing bar (7) first elastic rubber sealing ring (5) is housed and prevents that grout material from flowing out sleeve before solidifying, by simple slip casting, two prefabricated units are fused.
Description of drawings:
1: sleeve, 2: rib, 3: spacing preiection, 4: assembling reinforcing bar, 5: the first elastic rubber sealing rings 6: injected hole, 7: precast reinforced, 8: slurry outlet, 9: the second elastic rubber sealing rings.
The specific embodiment:
During the precast unit produce in factory, its end reinforced this ampuliform slip casting reinforcing steel bar connecting sleeve tube that is embedded with in advance, precast reinforced (7) are connected with sleeve (1) by second elastic rubber sealing ring (9), guaranteed the orientation problem of reinforcing bar and sleeve, reserve the position of injected hole (6) and slurry outlet (8), whole operation is simple and convenient.
When the prefabricated units that have an ampuliform slip casting reinforcing steel bar connecting sleeve tube lift at the construction field (site), Dui Jie assembling reinforcing bar (4) diameter is far smaller than the internal diameter of sleeve (1) with it, thereby reduced the difficulty of lifting, assembling reinforcing bar (4) seals by first elastic rubber sealing ring (5) with the gap of sleeve (1), inject the high strength grout material by the injected hole of reserving (6), and by slurry outlet (8) exhaust, thereby guarantee that slip casting is closely knit, behind the grout material setting and harden, precast reinforced (7) and assembling reinforcing bar (4) can be connected as one by combined type reinforcing bar branch sleeve and grout material.
The utility model is compared with existing product, and tube-in-tube structure is reasonable in design, is widely used, and construction technology is easy, and dependable performance is applicable to the fabricated construction of precast concrete.
Claims (1)
1. ampuliform slip casting reinforcing steel bar connecting sleeve tube, by sleeve (1), first elastic rubber sealing ring (5), second elastic rubber sealing ring (9) is formed, it is characterized in that: described sleeve (1) inwall is an ampuliform hollow, described sleeve (1) inwall is provided with the rib (2) of projection, described sleeve (1) bosom is provided with spacing preiection (3), described sleeve (1) two ends are provided with injected hole (6) and the slurry outlet (8) with internal communication, the thick bore end of described sleeve (1) is provided with first elastic rubber sealing ring (5), described sleeve (1) narrow orifice is directly held and is provided with second elastic rubber sealing ring (9), the thick bore end of described sleeve (1) is assembling reinforcing bar (4) insertion end, and described sleeve (1) narrow orifice is directly held and is precast reinforced (7) insertion end.
