Background technology
With the propulsion of building industrialization, China's assembled or assembled integral building are also gradually risen.Because China exists
In terms of assembled architecture and at the early-stage, key technology therein need to be furtherd investigate and developed, and between prefabricated components
Rebar connecting technology be exactly one of which key technology.At present, it is adapted to the bar connecting of assembled architecture mainly to have mechanical set
Three kinds of cylinder connection, grout sleeve connection and Hybrid connections etc..For the suitable occasion in operating space, these three connections can all make the best use of the advantages
Keep away and obtain having shortly：Mechanical sleeves operating space is larger and construction bothers, but cost is relatively low；Grout sleeve is easy to operate,
But cost is too high and the bad control of grouting quality；Hybrid connections are between the above two.
These above-mentioned connected modes are applied to conventional connection occasion, but for some bar connectings in particular cases,
Such as the wall of steel plate concrete nuclear power factory building and the bar connecting at floor node, preferable processing mode is there is no at present, is caused
Unit in charge of construction's operating difficulties and influence construction quality.Reinforcing bar at nuclear power plant's steel plate concrete wall plate node, worn in floor
Enter into steel plate concrete wall.Because construction of hydropower process is to lift the monoblock steel plate of floor most after first pouring walls concrete
Reinforcing bar at connection wall plate node afterwards, therefore it is required that can not there is reinforcing bar or sleeve to protrude metope on wall before lifting floor steel plate.
Current connected mode be pre-buried mechanical sleeves in wall, after floor hoisting steel plate, then the reinforcing bar at node is screwed onto pre-
Bury in sleeve.
Many problems be present in current this connected mode.First, embedded sleeve barrel positioning is more difficult in wall, it is necessary to
Sleeve is fixed on wall steel plate before pouring and punched place by walls concrete, and its position of influence that can not be vibrated by concreting,
Otherwise the later stage can not be with bar connecting.Secondly, the larger reinforcing bar used of nuclear power factory building floor size is relatively thick and long, is intended to reinforcing bar being screwed into
Embedded sleeve barrel is also extremely difficult, and the feedback of unit in charge of construction is not only to have influenceed construction speed but also influenceed construction quality at present, is converted
Cost is larger.If converted to grout sleeve, then can not both solve foregoing first problem, the also filling of uncontrollable sleeve within the walls
Slurry, and cost is also larger.Therefore, a kind of new attachment means are needed badly to substitute current connecting structure.
