Description
Technical field
The invention belongs to civil engineering component, be specifically related to a kind of ancient architecture timber frame frictional damping apparatus, be mainly used in the reinforcing of historic building structure Tenon node.
Background technology
The maximum feature of historic building structure is that between beam column, Tenon connects, need not nail one iron and make structure highly stable.Tenon node has certain bending resistance and friction energy-dissipating ability, but due to its special connecting mode, in all previous earthquake, timber frame easily occurs that node pulls out tenon, structure dodges askew phenomenon, for the reinforcing of Tenon node, extremely urgent.
At present, in Tenon joint reinforcing, modal method has ironware reinforcing, flat steel reinforced, CFRP reinforces and tinplate is reinforced.It is that Yu Liangxia ordered by steel plate that ironware is reinforced, and reinforcing bar inserts shaft, utilizes the resistance to tension opposing external loads of steel plate and reinforcing bar.Flat steel reinforced is by wooden frame and pin steel plate and screw joints, is realized the effect of reinforcing by the relative motion limiting beam column.It is be wrapped in around Tenon node by CRFP cloth that CFRP reinforces, and utilizes the resistance to tension opposing external loads of carbon cloth.Tinplate reinforcing is mainly reinforcing bar and directly orders on the beam column at Tenon node two ends.These four kinds of reinforcing ways all increase the natural frequency of structure, reduce the seismic response of structure, improve the bending resistance of Tenon node.But, destroy the working mechanism of Tenon node itself, weaken the shock resistance of structure simultaneously, even make ancient building destroy on originally damaged basis more serious.Existing reinforcement means more or less can affect the performance of historic building structure.
Consider that cushion technique obtains application in modern architecture, as damper can provide additional damping to structure, play cushioning effect.In earthquake, damper enters plasticity power consumption state antecedent in structure and is introduced into power consumption state, plays its power consumption effect, reduces the seismic response of structure own, and then effectively protect agent structure.But damper is reinforced rarely has application in historic building structure.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be historic building structure Tenon joint reinforcing frictional damping apparatus used.
The technical problem to be solved in the present invention avoids the secondary injury to historic building structure, and do not destroy the working mechanism of original component.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of ancient architecture timber frame Tenon friction of joint damper, for the reinforcing of Tenon node between historic building structure post beam.Mainly comprise the first sheet steel sections 1 connected with post, the second sheet steel sections 2 connected with beam, for connecting the first anchor ear 5, the second anchor ear 6 for connecting with beam with post.
First sheet steel sections 1 has first substrate 8, and the one side of first substrate is vertically fixedly connected with the first anchor ear 5 for connecting with post, and another side is vertically fixedly connected with three braces with holes, three braces with holes from and parallel to each other.
Second sheet steel sections 2 has second substrate 13, and the one side of second substrate is vertically fixedly connected with the second anchor ear 6 for connecting with beam, and another side is vertically fixedly connected with two braces with holes, two braces with holes from and parallel to each other.
Two brace intercalations with holes of second substrate 13 are between three braces with holes of first substrate 8, and the hole that pretension bolt secondary 4 inserts brace with holes completes the hinged of the first sheet steel sections and the second sheet steel sections.
Preferably, the material of described first sheet steel sections and the second sheet steel sections is steel.
Preferably, the material of described interleaf friction sheet is the rubber pad of leading.
Preferably, described first anchor ear and the second anchor ear material are mild steel.
Preferably, described first anchor ear is circular anchor ear, and described second anchor ear is square anchor ear.
Preferably, described damper device is applied to the reinforcing of ancient building Tenon node.
Ancient architecture timber frame Tenon friction of joint damper of the present invention is applied in the reinforcing of historic building structure Tenon node, alleviates the destructiveness of historic building structure under geological process.Apparatus of the present invention are semi-rigid, its operating principle is identical with the Energy Dissipation Mechanism of Tenon node, when earthquake occurs, first sheet steel sections and the second sheet steel sections produce relative rotation prior to Tenon node, by the Friction dissipation energy between steel plate, bear part geological process, reduce the seismic response of historic building structure.Under geological process, this damper device first bears a part of geological process, is consumed energy by the pivoting friction of this damping unit, reduces geological process to the injury of Tenon node, improves the energy dissipation capacity of Tenon node.Meanwhile, owing to adopting mild steel anchor ear to be connected with beam column by this damper, secondary injury can not be caused to timber.During use, only need this frcition damper to be arranged on critical positions, decrease the intervention to original structure; In addition, this damper device have volume little, install, safeguard and change the features such as convenient.
