Description
Technical field
This utility model is related to a kind of preset grouting material sleeve for building, prefabricated component attachment structure, is particularly suited for assembling
Formula building field.
Background technology
, by sleeve connection, sleeve is arranged on prefabricated structure for architectural industrialization prefabricated components upper reinforcement and lower rebar at present
In part, using upper reinforcement it is prefabricated when be connected with telescopic screw.Lower rebar insertion sleeve, is then made by preformed hole grouting
Upper reinforcement and lower rebar pass through sleeve connection.
Except installation procedure is more, slip casting is wayward, sleeve is difficult to dock with reinforcing bar, inserts difficult, peace conventional grout sleeve
Fill it is extremely inefficient beyond.Although conventional grout sleeve principle is feasible, due to grouting quality easily by grouting workman level,
The impact of the external conditions such as quality, the impact of responsibility, the impact of grouting material quality and weather, grouting quality cannot ensure,
Most fearful is that grouting effect or quality cannot effective detections.Or caused consequence is designer dare not be connected with grout sleeve
Connection technology, or increasing safety stock uses grout sleeve interconnection technique with caution, and assembled architecture is difficult to get around or root
Originally sleeve connection technology is can't steer clear of, therefore constrains the development of assembled architecture.Due also to conventional sleeve link cost is too high, greatly
Family is few with the component, the part that need grout sleeve connection intentionally, has a strong impact on the raising of assembled architecture assembly rate.
Utility model content
