Description
Technical field
The invention belongs to attachment device technical field, specifically a kind of building bar branch sleeve.
Background technology
In the prior art, the connection of reinforcing bar can use the specific methods such as welding, binding overlap joint, mechanical connection.Prefabricated dress
The connection of reinforcing bar is typically realized in connection with formula reinforced concrete member first, herein under the premise of realize the companies of other parts again
It connects.For example, in the connection procedure of prefabricated components, bar connecting is carried out first, then carries out the peripheral structures such as concrete again
The operations such as cast connection.Electric welding is such as used, needs the equipment such as electric welding machine, power cord, it is complex procedures, inconvenient for use, especially
It is in working at height, and it is even more inconvenience to pull and draw the equipment such as power cable and electric welding machine, due to the limitation of building site environmental condition, electricity
Source line often can not reach requirement, and inconvenience is caused to the construction in building site, and working efficiency is low, time-consuming and laborious, and
There are security risks.In Practical Project, it is contemplated that the degree of reliability of economy and joint performance, in the bar connecting of major diameter
In, most commonly used above-mentioned three kinds of bar connecting modes are the best mechanical connections of effect.External existing sleeve fills
In slurry technology, the connection between reinforcing bar is realized using the mode that sleeve is in the milk simultaneously, the Relative sliding between sleeve and reinforcing bar
Constraint is ensured by filler material；But because the shear resistance of filler material is limited, inevitable requirement uses very long set
Cylinder could meet basic performance requirement.It is intended that total better composite sleeve type bar connecting dress of technique effect after obtaining
It sets.
Also occurs the technical solution of some reinforcing steel bar connecting sleeve tubes in the prior art, such as application No. is 201711303739.X
A Chinese patent disclose it is a kind of being used for reinforcing bar Quick Connect Kit, including determine valve body and moving valve, which is characterized in that institute
It states and determines valve body and be threadedly coupled fixed steel bars with round-meshed end cap, it is described to determine to be equipped with outside limited block limit steel bar end in valve body
Face, and determine to have strip-shaped hole on valve body proximal cover one end, the first evagination body, the first evagination body up and down are equipped in strip-shaped hole
Centre is equipped with spring supporting built in slot, and telescopic rod is equipped in the spring, and connector threaded connection is set in the moving valve and is fixed,
Steel bars are fixed between connector and moving valve, and the moving valve and determine to have hole on valve body seal face corresponding position
By pin connection, it is arranged with the nearly moving valve side inner hollow of connector described in rubber ring outside connector, nearly reinforcing bar side is equipped with
Interior plug is threadedly coupled with connector.The technical solution can realize bar connecting, and principle is novel；But the structure of the program is multiple
Miscellaneous, the stability of connection is poor, and cumbersome, influences the joint efficiency of bar construction.
