Background technique
At present there are mainly two types of the connecting nodes of assembled architecture precast beam and prefabricated post, one is prefabricated beam-to-column joint sections
Point region is cast-in-place, and another kind is that bean column node region is prefabricated components.Domestic mainly to use the former, Japan uses the latter.Patent
CN105155683A describes prefabricated beam-column connection in a kind of assembly concrete building, through-hole is arranged in prefabricated post, in advance
Pre-buried beam indulges muscle in beam processed, and reinforcing bar passes through through-hole, connect by sleeve with the vertical muscle of beam, fixed with stirrup, cast-in-place concrete pours
In beam-column connection region.The connecting node meets the fabricated construction engineering method of precast concrete, but there are in column
Through-hole filling process is invisible, can not Grouted density in control through-hole, node, which moves to outside prefabricated post, increases cast-in-place region,
The problems such as sleeve dosage is more.It is cast-in-place that the cast-in-place mainly prefabricated pre-buried vertical muscle of beam column in prefabricated beam-column connection region protrudes into node
Completion is smash by setting up template and pouring in area, cast-in-place node region.This method not only needs to consider that precast beam indulges muscle and prefabricated post is vertical
The interference of muscle, it is also necessary to consider to indulge muscle evacuation between precast beam, this just considerably increases the difficulty of design and construction.Increase simultaneously
Cast-in-place node area sets up the work such as mold.Bean column node is that prefabricated component mode is mainly to reserve vertically in bean column node prefabricated component
Through-hole indulges muscle perforation node prefabricated component so as to prefabricated post, bean column node prefabricated component four sides stretch out reinforcing bar and by full grout sleeve with
Precast beam indulges muscle connection, sets up beam post-cast strip mold and pours and smashes completion.That there are working procedures is complicated for this method, plant produced is difficult,
It is at high cost, it is unfavorable for the problems such as transporting.
Summary of the invention
