Description
Technical field
The utility model relates to a kind of shaking-table test support model counter weight device, belongs to seismic testing field.
Background technology
Earthquake simulation shaking table experiment can reproduce the overall process of earthquake motion to structure function truly, thus the earthquake research carrying out structure for researcher provides instrument and research technique comparatively accurately.Shaking-table test model is often the structure of certain reduced scale, due to reduced scale effect, generally all needs the manual quality configuring certain proportion and weight on model during test.Manual quality generally adopts the larger cast iron of mass density or lead cast to form, and also has plenty of the precast concrete block of bulk quality.The placement of manual quality is by the corresponding site of bolt anchoring at model, and what have is then embedded in inside configuration, also has plenty of and is directly pasted onto model surface.
But, owing to being subject to the restriction of shaking table self-bearing capacity and resistance to tipping moment, when the shaking-table test of reality, test model can not carry out full configuration heavy dressing according to designing requirement completely and add manual quality, the placement of manual quality is comparatively difficult simultaneously, adds the design and installation difficulty of test model.In addition, because balancing weight is generally all placed on model surface, during test, balancing weight easily drops, and this all can have a negative impact to test model, shaking table equipment, data acquisition and personal security etc., adds the risk of test.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of shaking-table test support model counter weight device.
The scheme that the utility model technical solution problem adopts is a kind of shaking-table test support model counter weight device, comprise some weight set be made up of the concrete block of deformed bar anchoring and be arranged on the test model on table top, described weight set is anchored on counterweight support frame, described weight set one side is provided with lateral support plate, described lateral support plate is connected with connector one end, and described test model is connected with the connector other end by transfer beam.
Further, described support frame comprises the right column group of some compositions, two root posts in described column group are connected by crossbeam, two adjacent column groups are connected by limit longeron, two adjacent crossbeams are provided with middle longeron, described middle longeron is provided with some rolling support bases with roller bearing, described rolling support base is provided with the mass base plate for placing weight set, described column and suspension column support baseboard are hinged, and described suspension column support baseboard is connected with ground with expansion bolt by bar planting.
Further, described column upper end is provided with the strut rail beam preventing weight set from falling.
Further, described deformed bar is that essence pricks deformed bar.
Compared with prior art, the utility model has following beneficial effect: design a kind of counterweight fulcrum arrangement and the counterweight being placed on test model is changed put on the apparatus, the designing and making simplifying model, the test difficulty reducing model, and improve the security in process of the test; Without the need to specialized designs for compensating the manual quality because reduced scale reason increases, only need adopt the precast concrete balancing weight of standard, thus making test model superstructure design simple, easy for installation; Without the need to weight and larger-size balancing weight are fixed on the less test model of size, balancing weight is only needed to be placed on this fulcrum arrangement, and by rigidity transfer beam, model is connected with counterweight, Shaking Table Model test can be carried out easily, reduce tilting complex torque during model test, improve the test capability of shaking table equipment.
