Admittedly repair structure.
Background technology
Purlin purlin is the wooden component of building building width orientation stand structure in edge in ancient building carpentry work beam frame structure, between as each seam frame
The long wood of connection pulling and load-bearing effect, the big formula building title " purlin " of the Qing Dynasty are played, small formula building claims " purlin ", buildings of Song style Cheng " Bo ".
Frame, according to the location of " purlin ", can be divided into principal purlin, lower gold on hall inner beam Fu and eaves underbeam head, or between bracket set on column
Purlin, ridge purlin etc..Purlin purlin is the component for directly bearing roof load, and is transferred the load on beam and column.
In the Conservation and Renovation engineering of the big gallows timber of ancient building, it has been found that most of ancient building all there are purlin purlin rolling
Dodge, the phenomenon that roofing glides.Trace it to its cause be due to ancient building settlement of foundation it is uneven or in the presence of accidental load, it is special
It is not that ground movement acceleration will cause settlement of foundation uneven, cause when ancient building is acted on by seismic force or explosive force
Beam frame structure tilts, and then causes purlin purlin rolling to be dodged, and roofing glides.When meeting with the accidental load effect of excessive horizontal direction, example
Such as typhoon or impact, though this accidental load action time is short, its value is huge, and instantaneous horizontal active force is held more than building
Carry limiting value and will also result in the inclination of ancient building roof beam structure, purlin rolling in purlin is dodged.
Ancient building purlin purlin constructs with girder connection：Purlin purlin both ends, which are taken, is put on beam head, and dovetail is opened on purlin purlin both ends top,

Performance is weaker, in case of settlement of foundation is uneven or the effect of accidental load easily causes that purlin purlin rolling is dodged, roof-base glides, and then
Cause roofing ash backing layer cracking failure, roof draining rain.
At present, the purlin purlin in the big gallows timber of ancient building is repaired with beam head overlapped joints is reinforced using cramp iron, will
Beam head and the position of Heng Lin lap-joints are fixed up with cramp iron, to prevent the rolling of purlin purlin from dodging, although this reinforcement measure rigidity compared with
By force, but pliability, anti-torsion ability are insufficient；In case of uneven settlement of foundation or earth shock easily cause cramp iron and beam head and
The connecting portion of purlin purlin loosens, and causes reinforcing member to fail, so that the security of node is still on the hazard.Secondly, metalwork adds
Gu during node, wooden component is often destroyed during cramp iron build-in wood component；Change the raw material of historic building structure
