Technical problem to be solved in the utility model is, a kind of prefabricated assembled Steel Reinforced Concrete Members attachment structure is provided, cast-type Steel Reinforced Concrete Members is realized that batch production is prefabricated, industrialized construction, and ensure the ductility of prefabricated assembled steel reinforced concrete structure, energy consumption ability, realize that Contraction in Site is rapid, construction quality standardization simultaneously.
This utility model solves its technical problem and the technical scheme is that
A kind of prefabricated assembled Steel Reinforced Concrete Members attachment structure, including prefabrication type steel concrete member, adapter, prefabrication type steel concrete member is pre-formed by concrete and shaped steel, and the shaped steel end head of the reserved certain length in prefabrication type steel concrete member two ends, shaped steel end head reserves shearing resistance keyhole；Adapter is pin grout sleeve formula, two U-shaped fasteners including split, U-shaped fastener is welded with the shearing resistance bolt that the shearing resistance keyhole reserved with shaped steel end head is corresponding, and reserve semicircle injected hole, when two U-shaped fasteners fasten, two semicircle injected holes form complete circular injected hole, and the length of adapter is 2 times of shaped steel end head length in reserve.
Adopting this utility model of technique scheme, compared with prior art, its prominent feature is:
Mechanical connection and grouting connection are combined as a whole, decrease the impact of wayward factor during existing node connects, ensure that the reliability that steel reinforced concrete node connects, and the field operation of cast-type steel reinforced concrete structure is completely converted into prefabrication processing, ensure that the standardization of the Optimum utilization of construction material and construction technology, and simplify construction technology, reduce the requirement level to site operation technology, assembling is quickly spliced at the complete prefabricated processing and the scene that really realize steel reinforced concrete structure, it is ensured that the entirety of building structure is standardized and construction quality.
As preferably, this utility model further technical scheme is:
Shaped steel in prefabrication type steel concrete member is I-steel.
When two U-shaped fasteners of adapter fasten, the external diameter of adapter is less than the external diameter of prefabrication type steel concrete member.
