Property test and experiment device, belongs to Architectural Mechanics test and experiment device field field.
Background technique
In China especially in high intensity Zone, grassroot project specific gravity is accounted for using the construction project of seismic isolation technology and is increasingly increased
Add.However the practical isolation property of shock-insulation building whether meet specification and design related request and set objective then must not and
Know.Therefore the isolation property of the structure is examined to be very important by the entity in situ test of shock-insulation building.
The dynamic characteristics of structure includes natural frequency of structures, the vibration shape and damping ratio etc., is that geological process flowering structure responds
Deciding factor.Existing structure Methods for Measuring Dynamic Characteristics mainly has natural excitation technique, first displacement method, steady-state sine excitation method
Deng different test methods can be selected according to required purpose.Wherein just displacement method of testing is applied to a certain degree to test structure
Initial displacement, then release makes isolation structure generate free vibration suddenly, and then measures a kind of survey of its structural dynamic performance
Method for testing.This method has the features such as with strong applicability, controllable flexible.Based on existing research it is found that just displacement method of testing is to visit
Study carefully shock-insulation building practical isolation property is more direct and effective test method.
Currently, just the key technology of displacement method of testing is that initial displacement applies and unloads, wherein unloaded operation is to a certain degree
Determine the authenticity and accuracy of test.However there is certain office in the unloading manner being just displaced in testing experiment at this stage
Limit, when such as directlying adopt hydraulic jack unloading, jacking header return is slow, when discharge time is longer than shock isolating pedestal return
Between, this will generate certain restrictions or constraint to the free vibration of shock-insulation building；When being unloaded using blasting procedure, such as application No. is
The Chinese patent of 201710410038.X will generate the detonation shock of disturbed test result, influence the accuracy of test result.
In addition, the bringing device being just displaced mainly uses hydraulic jack, is come directly towards by hydraulic jack and shock insulation is pushed to build
Given level needed for generating testing experiment is built to be displaced.However for the shock-insulation building of the different scale of constructions, the initial displacement that is applied
Size is also not quite similar, i.e., will select the hydraulic jack then with different lifting capacities and different trips height according to test demand.
Simultaneously in the first displacement method of testing of shock-insulation building, the arrangement of hydraulic jack is arranged horizontally.
However, the hydraulic jack roof support means used in existing testing experiment are generally the Simple welding steel being fixed temporarily
Frame builds platform, and its dimensions is only capable of being applicable in the jack of a certain specific model.Apply when to different shock-insulating buildings
When different size of initial displacement, it is often necessary to remake the support device of different model, this makes existing support device difficult
Be recycled, it is poor for applicability；The waste of unnecessary manpower and material resources is caused simultaneously.
Summary of the invention

In order to better understand the present invention, the working principle of the invention is made below with reference to above-described embodiment primary complete
Description:
When using experimental rig, first should the hydraulic jack 2 to experimental rig install.Choose hydraulic jack
Behind top 2, the second support plate 52 is slided first along horizontal screw bolt 53, adjusts the second support plate 52 and 51 spacing of the first support plate
From, and the second support plate 52 is fixed with Level tune nut 58；Then the height that adjusting knob 5422 adjusts lifting screw 541 is held
Degree, or the height that mechanical adjusting nut 5421 adjusts lifting screw 541 is rotated by spanner, it will be on lifting leveling component 54
First support plate 51 and the second support plate 52 are adjusted to proper height；Its secondary side observes horizontal bubble 59, side fine tuning lifting leveling
Component 54 levels the first support plate 51 and the second support plate 52；Then fixed 2 both ends of hydraulic jack will be needed, placed
In the arc groove 55 in the first support plate 51 and the second support plate 52；Jack fixing bolt 57 is finally rotated, to arc groove
Hydraulic jack 2 in 55 is fixed.
When load, hydraulic load is applied by hydraulic jack 2, pushes hydraulic jack top to be subjected to displacement, completes set
The application work of initial displacement；The bar card slot 331 that sticks up for sticking up 33 one end of bar at this time is fastened on a shape hook housing II 321, the other end
Grab hole 332 hangs the grab 341 on 34 top of kelly, limits to the second unloading block 32, prevents it from falling during loading
It falls.
In 2 release of hydraulic jack, spring 43, which is shunk, generates pulling force, accelerates the top return of hydraulic jack 2, simultaneously
Operator is detached from grab 341 out of grab hole 332 by external force, sticks up bar 33 and disappears to the fixed function of the second unloading block 32,
And using door door shape hook housing as fulcrum, carry stick up bar 33 upwards, makes the first unloading block 31 and the second unloading block 32 that relative separation occur,
Second unloading block 32 occurs to fall downwards under the effect of gravity, is finally detached from hydraulic jack and shock-insulation building, convenient and fast
Unloaded operation is completed fastly.
The return of Normal hydraulic jack test device, hydraulic jack top needs the regular hour, discharge time phase
To longer, initial displacement is different according to applying, and the time that unloading block is fallen downwards is about 40~60s.And the present invention is using mutual
It is bonded the first unloading block 31 and the second unloading block 32 on inclined-plane, different according to initial displacement is applied, the second unloading block 32 falls downwards
The time fallen is 5~10s so that the present invention in uninstall process hydraulic jack 2 to the limitation of the free return of shock-insulation building and
Constraint becomes smaller, and in order to which shock-insulation building can preferably occur during just displacement testing experiment and complete free vibration, has
Effect improves the accuracy and operability of test result.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
