Description
Technical field
The invention belongs to field of civil engineering, are related to a kind of test platform, and in particular to a kind of assembled high temperature load examination
Test platform.
Background technique
Under high temperature of fire, the mechanical property of structural material has a degree of decaying, causes structure and component in high temperature
Under bearing capacity decline finally cause structure to generate and certain damage or even collapse.On September 11st, 2001, World Trade Organization, the U.S. is big
Tall building collapses under high temperature of fire because serious fire, main structure occur after the collision by aircraft, ultimately causes about 2998
People is dead, and similar serious building fire case occurs repeatedly.Therefore the high temperature load test of test specimen has structure design
Important meaning.
In front member hot test research, it is limited to test apparatus, most of hot tests can only be using static preloading
Or jack load is until the test model that test specimen destroys, this loading method cannot achieve Bit andits control in loading procedure.But
It is in reality, test specimen raising temp and loading process must realize that Bit andits control could accurately test test specimen and reach a high temperature bearing capacity
The later unloading course of peak value, therefore current test mode cannot test the overall process mechanical response of test specimen under high-temperature condition.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of existing high temperature load test means, a kind of assembled high temperature for providing
Loading test platform, the high-temperature test system which supports, applicability and operability with higher allow test specimen to meet high
While Wen Shouhuo, the pressure that the progressive load maximum value of Bit andits control is 1000 tons realizes high temperature furnace and 1000 tons of servo-type pressures
Power machine matches.
The technical solution adopted by the present invention are as follows: a kind of assembled high temperature loading test platform, including horizontal supporting system
More girder steels, more steel columns of vertical support system, horizontal sliding system pulley blocks and unequal angle, connecting plate and spiral shell
It tethers and connects accessory；
Pass through connecting plate between the girder steel and steel column, be bolted；The girder steel and steel column are H profile steel or I-shaped steel
At；
The end of the girder steel passes through unequal angle with ground, is bolted；
The end of the steel column is connect with ground by ribbed stiffener, expansion bolt；
The pulley system includes V-type pulley and guide track system, guide track system by flat hot rolled bar and cold-drawn round steel welding and
At, and connect by bolt with girder steel.
Preferably, being bolted between the flat hot rolled bar of the pulley system by 8.8 grades of M6*20, by cold-drawn round steel
It is welded on flat hot rolled bar by point as guide track system.
Preferably, being bolted between the girder steel and steel column by connecting plate and 8.8 grades of M16*40.
Preferably, the end of the steel column is connect with ground by ribbed stiffener and M16*150 expansion bolt.
Preferably, the end of the girder steel is connect with ground by unequal angle, angle steel short side and girder steel pass through 8.8
Grade M16*40 is bolted, and angle steel long side is connect with ground by M16*150 expansion bolt.
Preferably, when the experiment porch is built in underground, can upper cover 8mm thickness diamond plate, and ensure diamond plate and ground
Between at least contact length of 50mm.
The present invention is mainly bolted, and guarantees meet the needs of fast industrialization in the case where bearing capacity.Girder steel, steel
Column section and bolt quantity are determined according to Force Calculation.Test specimen is installed in pulley system after being put into stove, then is pushed into 1000 tons
It is fixed in press machine.While the present invention allows test specimen to meet high temperature by fire, Bit andits control loads the pressure that maximum value is 1000 tons,
Realize matching for high temperature furnace and 1000 tons of servo-type press machines.
The utility model has the advantages that the present invention passes through assembled high temperature loading test platform, while allowing test specimen to meet high temperature by fire, position
Moving control load maximum value is 1000 tons of pressure, realizes matching for high temperature furnace and 1000 tons of servo-type press machines.Simultaneously
The test platform meets the needs of fast industrialization, can be in factory's preprocessing, and directly lifting splicing at the construction field (site), is high temperature
The popularization of load test has a foreshadowing.
