The lower the two connection of effect is reliable.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the class socket joint of a kind of column and adjacent members
Connection structure, the adjacent members including prefabricated stand column and with prefabricated stand column cooperation, the adjacent members are connect with prefabricated stand column
Face be known as joint face, it is characterised in that take retraction processing to form post end retraction section in prefabricated stand column end, column is pre-
It buries reinforcing bar and stretches out column, groove is set on adjacent members joint face, groove size is greater than prefabricated stand column standard paragraphs size, adjacent structure
Part embedded bar stretches out groove, and bottom portion of groove pours seat pulp layer, and prefabricated stand column lifting positioning sits slurry in groove, column pre-buried steel
The embedded bar of muscle and adjacent members mutually overlaps, and pours ultra-high performance concrete after groove is interior, makes prefabricated stand column and adjacent members
It connects integral.
Further, the section of the prefabricated stand column end retraction section, which is retracted, is respectively retracted 10 ~ 15cm having a size of column two sides,
Guarantee column, which stretches out embedded bar and poured in ultra-high performance concrete after, enough protective layer thickness, while can meet column and hang
Set the stress and stability needs of position.
Further, the groove on the adjacent members joint face, cross dimensions are that column standard section two sides are respectively expanded
Big 10 ~ 15cm, guarantee adjacent members, which stretch out embedded bar and poured in ultra-high performance concrete after, enough protective layer thickness.
Further, the groove on the adjacent members joint face, the column embedded bar that depth should be 12 ~ 14 times are straight
Diameter guarantees there are enough anchorage lengths when the embedded bar of column stretching embedded bar and cushion cap mutually overlaps, through a large amount of reinforcing bars
It is studied with ultra-high performance concrete adhesion test, the column embedded bar diameter of the lap of splice >=10 times can be met the requirements.
Further, the adjacent members are cushion cap or bent cap.
The utility model utilizes the characteristics of early strong and bonding strength of ultra-high performance concrete is strong, Self-leveling is convenient for construction,
Reduce construction subsequent waiting time and cushion cap expand depth of groove, increase the reliability of connection, and simple structure, convenient for applying
Work is easy to guarantee the quality of prefabricated components connection, has preferably promotional value.Compared with prior art, the utility model
Beneficial effect is:
One, using retraction processing, (two sides are only respectively retracted 10 ~ 15 to the prefabricated reinforced concrete post end of the utility model
Cm), it is ensured that the stress and stability of column lifting positioning need.
Two, the prefabricated reinforced concrete post end of the utility model is handled using retraction, and cushion cap groove is using at expansion
Reason, it is ensured that the embedded bar of column embedded bar and cushion cap has enough protective layer thickness when mutually overlapping, and increases connection
Reliability.
Three, the utility model is using ultra-high performance concrete and the strong feature of bonding strength, and the depth of groove is only 12 ~
The diameter of 14 times of column embedded bar, substantially reduces the depth of cushion cap rim of a cup in bayonet joint.
Four, the utility model feature early strong using ultra-high performance concrete, pours 3 days or so in ultra-high performance concrete
It can be carried out subsequent construction, reduce the construction waiting time.
