Description
Technical field
The present invention relates to field of civil engineering more particularly to a kind of prefabricated assembled concrete member stress bar connecting to use
It starches the bar connecting that pin bank is closed and closes full grout sleeve with slurry pin bank.
Background technology
Development fabricated construction, main member is promoted to be prefabricated in the factory life currently, country advocates building industrialization energetically
Postpartum carries out the assembly of prefabricated components to scene, and component is connected as overall structure, and between prefabricated components steel bar stress can
It is the key factor for influencing structure general safety and stress performance by connecting then.National sector standard《Prefabricated concrete structure
Technical regulation》JGJ1 has carried out relevant regulation to the connection method of prefabricated components, according to the rules, the application of sleeve grouting connection
Range is wider, connects reliability higher, can be applied to the connection between vertical member in bridge structure.
Since the weight and volume of prefabricated components is typically much deeper than building structure, bar diameter used in bridge structure
Also larger, and the connection of Large-size rebar is conducive to construct, therefore, being proposed to the sleeve grouting connection of Large-size rebar needs
It asks.Had in connection using the reinforcing bar of major diameter in prefabricated components convenient construction, can quick-assembling, erection tolerance it is big
The advantages that, meanwhile, diameter, which increases after sleeve length wall thickness, all to be needed to increase, this makes existing sleeve processing more difficult, and even
The performance of increase grouting material when connecing due to bar diameter is also required to improve, to meet the performance requirement of connection.
Therefore, a kind of full grout sleeve of bar connecting slurry pin bank conjunction must be provided by, which having in fact, solves above-mentioned technical problem.
Invention content
The technical problem to be solved in the invention is to provide a kind of providing the reinforcing bar reliably connected for prefabricated components reinforcing bar
Connection closes full grout sleeve with slurry pin bank.
In order to solve the above technical problems, the present invention provides a kind of bar connecting slurry pin banks to close full grout sleeve, including
In the grout sleeve body of hollow columnar, through the grout sleeve body setting pin hole, be inserted into the pin hole and fixation
In the grout sleeve body pin, extend through the grout sleeve body and spaced setting injected hole and plasma discharge hole,
