Abstract
The utility model discloses a take half grout sleeve of threaded connection spare, this half grout sleeve include threaded connection spare (5), cover barrel (2), be in the milk mouth (3), grout outlet (4) and elasticity rubber seal (7), in, the one end in the cover barrel (2) is equipped with threaded connection spare (5), and the other end is equipped with elasticity rubber seal (7). Be equipped with grout mouthful (6) and grout outlet (7) on the outer wall of cover barrel (2) side. One end and threaded connection spare (5) of fixed side spiral (1) meet, insert the one end of side spiral (8) and pass elasticity rubber seal (7). Cover barrel (2) inner wall is offered threadedly, has the connecting piece internal thread to open with the outside in threaded connection spare (5) and has the connecting piece recess. The utility model discloses for traditional sleeve, increased the mortar bond stress, improved steel bar connection's firm degree, simple manufacture has, and advantages such as low cost be particularly useful for the connection of roof beam, post, shear force wall component longitudinal reinforcement, but the wide application have wide engineering application prospect in prefabricated concrete structure.
Description
Technical field
The utility model is related to a kind of grouting anchor sleeve connector for bar connecting between precast concrete, belongs to
In construction engineering technical field, half grout sleeve of half grout sleeve of specially a kind of provided with threaded connector.
Background technology
It is known that prefabricated assembled concrete structure is a kind of version meeting industrialized production, have
Speed of application is fast, labour intensity is low, noise pollution and the advantage such as wet trade is few and product quality is easy to control, is China's future architecture
Developing direction.
The core of prefabricated assembled concrete structure and difficult point are the connectivity problems of reinforcing bar.Common bar connecting form has
Be mechanically connected, be welded to connect, overlapping connection etc., but all deposit need to pour at connecting node upon connection after the asking of pouring concrete
Topic, the reinforcing bar that stretches out of another part can be inserted during construction with pre-plugged in concrete member by cement grout sleeve connection
In the corresponding sleeve of this part, then ungauged regions high strength cement mortar is poured into branch sleeve, fill up between sleeve and reinforcing bar
Gap, after cement mortar hardening, two reinforcing bars are just securely joined together, thus reaching the purpose connecting two end bars, even
Connect and rear pouring concrete at node, need not be poured, the joint efficiency of node is higher.
At present, China various places are put into effect related specifications of prefabricated concrete structure, in code the connection of reinforcing bar recommend to adopt
Connected with grout sleeve.This is primarily due to, and compared with other connected modes, grout sleeve connection has the advantage that：①
Technology maturation；2. connect reliable.Abroad substantial amounts of engineering practice proves, this method of attachment is simple to operation, and joint effect is good
Good.
Grout sleeve is divided into full grout sleeve and half grout sleeve by version, and the joint two ends of full grout sleeve are all adopted
Connect reinforcing bar with the mode of grouting；Joint one end of half grout sleeve adopts grouting way to connect reinforcing bar, and the other end adopts non-filling
Slurry mode connects reinforcing bar, and the usual other end uses threaded form.
There is mortar bond stress deficiency in half traditional grout sleeve, bar connecting difficult quality controls, processing difficulties, form
Heavy, high cost disadvantage, is unfavorable for the development of current China housing industrialization and building industrialization.
Utility model content
For solving the problems, such as to work as first half grout sleeve, a kind of half grouting set of provided with threaded connector of the utility model
Cylinder, including threaded connector (5), sleeve body (2), grouting mouth (3), grout outlet (4) and elastic rubber sealing ring (7), in, sleeve
One end in body (2) is provided with threaded connector (5), and the other end is equipped with elastic rubber sealing ring (7).Outside sleeve body (2) side
Wall is provided with grouting mouth (6) and grout outlet (7).One end of affixed side spiral (1) is connected with threaded connector (5), insertion
One end of side spiral (8) passes through elastic rubber sealing ring (7).
Described connector (5) is provided with connector internal thread and the recessed grain of connector.
Described sleeve body (2) is seamless steel pipe, and inner side is provided with screw thread.
Described elastic rubber sealing ring (7) internal diameter is little compared with insertion side spiral (8) diameter, and external diameter is compared with sleeve body (2)
Internal diameter is big.
Beneficial effect：The utility model, with respect to conventional sleeve, increases mortar bond stress, improves the jail of bar connecting
Gu degree, there is making simply, the advantages of with low cost, be particularly suited for beam, post, the connection of shearing wall member longitudinal reinforcement,
Can be widely applied in prefabricated concrete structure, there is wide future in engineering applications.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is made an explanation
As shown in figure 1, a kind of provided with threaded connector of the present utility model half grout sleeve, including：Connector 5, set
Cylinder 2, grouting mouth 3, place's slurry mouth 4, elastic rubber sealing ring 7.On described connector 5, inner side is provided with connector internal thread, outward
Side is provided with the recessed grain of connector.During use, one that is provided with elastic rubber sealing ring 7 can be inserted directly into reinforcing bar 8, be provided with screw thread
One of connector 5 is threaded connection part 5 and is connected with the reinforcing bar 1 being provided with screw thread silk head.
