Technical field
The present invention relates to the Conservation and Renovations of ancient building roofing timber structure layer, particularly relate to a kind of pair of ancient building unrest joining seam formula Rafter and purlin node carry out reinforcing repairerment method.
Background technique
Rafter category large historic building wood member, is between the purlin and roof boarding in roof beam structure, and frame is on upper and lower purlin and purlin, by one Fixed sequence or positive angle or oblique angle arrangement.Its section has circle and rectangular two kinds.According to its position, " rafter " has different appellations, Such as: eave-rafter, brain rafter, intermediate rafter.Root it was found that rafter has just been used early in the epoch of " structure wood be nest ", but at that time due to Roofing be face directly, so, what " rafter " actually play a part of is purlin, and the drop type roof of Han dynasty shows that Han dynasty has multistage " rafter ";The curved roof of the Northern and Southern Dynasties results in the diversification of " rafter ".In feudal society, the production of " rafter " has sternly The hierarchy of lattice, such as " national language " are once recorded: the palace " rafter " of emperor will not only polish, and also want textured;On nobility house " rafter " can only polish;" rafter " on court official house is as long as cut circle.In short, constituting the component of historical timber frame Other than beam, column, a tree, used in making timber for boats, purlin, there are also the plank bases such as the rafter of roofing, roof boarding and its Accessory Members.The arrangement of ancient building rafter Form can be divided into: random joining seam and oblique slap two classes;Random joining seam refer to it is parallel between rafter head and rafter head rely on, it is oblique staggeredly, such as it is thorough It is upper it is bright make roof beam structure, its rafter head can be peeped and be staggered state.The oblique palm refers to by ridge step, gold step and each step rafter head such as eaves portion, according to raising-and-depression Scale is sawn into inclined-plane, is allowed to be overlapped intersection up and down when following closely rafter, and followed closely and reinforced with rafter.
Ancient building wood roof decking, which refers to, is formed by structure sheaf between the wooden rafter and the wood sheathing held thereon, it is to ancient architecture The health for building roofing plays very important effect.Since ancient building roof truss is timber structure, if wood roof decking grain is rotten or damaged, It must lead to roofing ash backing layer cracking, roof roof leaking, cause roof system grain is rotten to rot, and then influence whole building gallows timber Stress intensity.The roofing of ancient building is complicated structural system, rafter bear by roof boarding transmitting Lai roof load, and by this For a little load Transmit evenlies to purlin, wherein whether rafter has enough intensity and bearing capacity, and can be effectively by roofing Load Transmit evenly is an important indicator for investigating ancient building roof-bearing system to purlin purlin.It can be seen that rafter is exactly Strong " bodyguard " of ancient building roof construction layer.Component one of of the rafter as wood roof decking, directly with the ash in grey backing layer Mud contact, last a very long time, roof leakage will cause roof boarding and the grain of rafter is rotten;So the reinforcing of rafter is historic building structure Frequently problem in renovation project.
