Description
Technical field
The present invention relates to a kind of km grade high-rise building air spring pole and production methods, and in particular to one kind adjustable thousand
Meter level high-rise building air spring pole and production method belong to civil engineering wind resistance technical field.
Background technology
Into 21st century, with the extensive use of high-strength light material, the appearance of new structural systen and advanced build
The development of technology is made, various countries propose to build the high-rise building of " world's highest " one after another.Highest building in the world's is 160 at present
The Harry method towers of layer, 828m high, and build one that a km grade high-rise building has become international building development from now on
Inexorable trend.In general, such building depth-width ratio is big, rigidity and damping ratio are small, belong to wind sensitive structures, wind load is often
As the control selector of its structure design.Accurately to determine its designed wind load and evaluating its wind resistance, it should be carried out
Aerodynamic model test is studied, the wind-excited responese of direct measurement structure.
However for now, there are no propose for multitower connector high-rise building air spring pole design method,
Therefore the aeroelasticity effect of structure can not be furtherd investigate.Further, since existing air spring pole design method fails very
Plug connectivity problem is handled well, is caused designed model that can not really realize the continuous adjustability of rigidity or frequency, is caused
Many important likelihoods ratio are unable to get accurate satisfaction.Accurately to study the gas bounce effect of connected multi-towers high-rise building, need
It is proposed a kind of air spring pole design method that can simulate its aerodynamic configuration and structural dynamic characteristic, and made model can
Realize the Parameter adjustables such as rigidity, damping, quality.
Invention content
The present invention is to solve the problems, such as that model dynamic characteristics can not be continuously adjusted in existing wind tunnel test, and then propose a kind of
Adjustable km grade high-rise building air spring pole and production method.
The present invention is adopted the technical scheme that in order to solve the above problem：Model of the present invention include model base plate,
Multiple rigid platfor plates, multiple cartridge units and several stainless steel lead screws, multiple rigid platfor plates are from top to bottom set gradually
Mould there are one being set between the top of model base plate, bottom rigid landing slab and model base plate according to construction profile design
Type coat plate, interior by several perforations from top to bottom the stainless steel lead screw of coat plate, can be by model by stainless steel lead screw
Superstructure is fixed on model base plate；It is laid with three sets between two neighboring rigid platfor plate in addition to bottom
Cylinder unit each has two perforation ground stainless steel lead screws from top to bottom, two neighboring rigid platfor plate in the cartridge unit
Middle part between be equipped with cylindrical sleeve, have a perforation ground stainless steel wire from top to bottom in each cylindrical sleeve
Bar.
Production method of the present invention is as follows：
Step 1: the bottom of seven stainless steel lead screws is welded together with bottom nut, and bottom nut is embedded in mould
In the first sliding groove of type base board；
Step 2: model base is fixed on wind-tunnel turntable；
Step 3: being screwed into 7 fixing nuts to model base plate upper surface, hold out against, to fixed stainless steel lead screw；
Step 4: 7 location nuts of installation, positioning is positioned over by the first layer rigid platfor plate for being bonded with bottom coat plate
It is levelling on nut；
Step 5: being screwed into 7 fixing nuts respectively to rigid platfor plate, hold out against；
Step 6: 7 location nuts of installation, second layer rigid platfor plate and corresponding upper section sleeve are put to location nut
On, it is levelling；
Step 7: being screwed into 7 fixing nuts respectively to rigid platfor plate, hold out against；
Step 8: repeating step 6 to step 7 until installing the tenth layer of rigid platfor plate；
Step 9: tentatively adjusting the architectural characteristics such as quality, rigidity, damping, and measure；
Step 10: using elasticity of wood, by lower section sleeve across lead screw, and it is screwed in rigid platfor plate corresponding positions
Set place；4 top layer sleeve coat plates are installed；
Step 11: measurement structure dynamic characteristics；
Step 12: if the model likelihood ratio is unsatisfactory for requiring, removes section sleeve and top layer sleeve, release under every layer and be located at
The fixing nut of rigid platfor plate upper surface, repeats step 9 to step 11.
The beneficial effects of the invention are as follows：The present invention is since model inner space is from bottom to top perforation, so can will add
Speedometer is placed in inside configuration, to eliminate the interference of measuring instrument stream field, improves the precision of measurement result.The mould

It is more than platform with outside first layer rigid platfor coat plate part below, by being divided into for the sleeve equal length between every two layers of rigid platfor
Upper section sleeve and lower section sleeve, sleeve are the hollow cylinder that veneer material surrounds, and lead screw without hindrance can pass through；Every layer of upper section sleeve packet
It includes 1 section circular cylinder of centre and oval cylinder is saved on periphery 3, be assembled convenient, every layer of upper section sleeve is connected to High tack adhesive
It is common assembled to form an assembled rigid unit on the rigid platfor of this layer of corresponding position；It includes centre that sleeve is saved under every layer
Oval cylinder is saved on 1 section circular cylinder and periphery 3, wherein the oval cylinder bottoms of 3 sections connect that there are one the ring-types for being provided with 4 screw holes
Tail portion is then equipped with the annular undercut region for being provided with same screw hole on corresponding rigid platfor plate, and when assembled, screw rod can
It sequentially passes through upper and lower two holes, lower section sleeve is fixed on rigid platfor plate, after the completion of assembled, rigid platfor surface becomes one
Flat surface.Convenient for assembly, the oval cylinder of lower section sleeve and its cyclic annular tail portion are equal in the end close to intermediate circular cylinder
It is provided with a fine crack, can be expanded fine crack using timber natural resiliency when assembled, to be allowed to smoothly then be fixed across lead screw
In on rigid platfor plate, this measure overcomes each the drawbacks of will dismounting entire model again when adjusting lead screw position, greatly
Assembled efficiency is improved, this is also the important innovations place of the present invention；After the completion of upper and lower two sections sleeve assembly, centre can be there are
The gap of 1mm wide, for avoiding contribution of the coat plate to structure overall stiffness；The sponge block of the present invention is filled in two in oval cylinder
It is damped in gap between root lead screw with achieving the effect that friction energy-dissipating, adjusting.
