Description
Technical field
This utility model relates to the prestressing force intensifier of a kind of continued access timber structure.
Background technology
On the architectural history of China, historic building structure occupies a very important part undoubtedly, and as the rarity of China's art of architecture, its historical role is attracted attention very much.Being structurally characterized in that of timber structure itself, draws materials conveniently, and speed of application is fast and simple, has good energy dissipation ability simultaneously.But, due to the characteristic of timber structure itself, along with the growth of the time of use, easily there is certain damage in itself.For the purlin at wooden roof place, wattle and lift the component such as beam, floor beam, often damage by worms, tide rotten so that this class A of geometric unitA loses bearing capacity.
At present, common timber structure has two kinds: one class to be tradition repairerment method for the strengthening by reparative method method of this class A of geometric unitA, by whole component is replaced, component is disassembled by the method from total, new component is installed, to reach the purpose repaired, for this kind of method, its applicable surface is narrower, girder construction and roof structure is lifted especially for large-scale, it is changed component and there is the problem needing frame, and the frame that falls of large-scale timber structure needs bigger quantities, and difficulty of construction is big, need timber engineering teacher possessing rich experiences, substantial amounts of manpower and materials are supported, when the repairerment carrying out historic building structure is safeguarded, the repairerment principle adhered to be " with old repair old ", and change component method and destroy the history relic value of component itself undoubtedly, therefore, repairerment field at ancient building, the application changing component method is few.The second strengthening by reparative method method be by by occurring seriously to damage by worms, tide is after rotten position blocks, by rotten Partial Resection, again two components separately are carried out continued access, compared with first method, this kind of repairerment method, without carrying out falling frame, directly carries out the repairerment of component in original place, quantities is greatly reduced, but this kind of method there is also certain deficiency, that is, through the component of continued access, the intensity of itself and rigidity are compared and be there have been previous a degree of reduction.Particularly in continued access place, it is become pin joint from original affixed point, and depression of bearing force is obvious, and therefore through the component of continued access, its component bulk strength and rigidity have been not so good as integral component before.
Renovation reinforced for such continued access component, common engineering method is to be repaired by affixing carbon fabric direct on continued access component, and this kind of method has an a degree of lifting for the intensity of continued access component, but in rigidity lifting limited efficiency.Meanwhile, such repairerment method belongs to passive enforcement method, it is impossible to just reduce the mid-span deflection of component in carrying early stage.
