An air cylinder (4) is mounted on a reaction bracket (8); the bottom of the reaction bracket (8) is fixedly connected with a working platform (10); the air cylinder is sequentially connected with an air pressure switching valve (3), an air pressure regulating valve (2) and an air compressor (1) by pipelines; a load sensor (6) is mounted at the end part of a piston (5) of the air cylinder; and the load sensor (6) is connected with an electronic load display by a line. Compared with the prior art, the whole device can well ensure the stability of a load, and the guarantee is provided for ideal static bearing. According to the load needed by a test, air pumps with different measuring ranges are selected; through a stable air supply, the air pressure is regulated to adjust the load to a sample; and furthermore, the load can be kept continuously. The load is stable, and further, the manufacturing cost of equipment and the testing time cost are lower. The device is quite suitable for the tests with the standard load keeping requirements and similar continuous load keeping requirements.
Description
[technical field]
The present invention relates to the static bearing test device of a kind of raised floor, can be widely used in the static bearing test of all kinds of raised floors.
[background technology]
At carrying out the specific (special) requirements of around-the clock static bearing test to raised floor among the standard P SA MOB PF2 PS/SPU-1992 (raised floor-performance provision).
At present, the equipment of the static bearing test of raised floor all is to adopt universal testing machine.And general universal testing machine all is hydrostatic control, and load has fluctuation to a certain degree in the test, is not complete static state, and continuous working 24 hours, and to the loss of equipment, time cost is all bigger.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and provide a kind of raised floor static bearing test device.Adopt the principle of counter-force, utilize air compressor to provide stable source of the gas for cylinder, regulate air valve, control air pressure can be controlled the load that raised floor is applied, and can read the suffered load of sample by the sensor that is connected between cylinder and the sample.
Design the static bearing test device of a kind of raised floor for achieving the above object, comprise air compressor 1, air pressure regulator 2, baroswitch valve 3, cylinder 4, load transducer 6, electronics load display 7 and reaction frame 8, it is characterized in that: described cylinder 4 is installed on the reaction frame 8, described reaction frame below is provided with worktable 10, described cylinder connects baroswitch valve 3, air pressure regulator 2, air compressor 1 successively by pipeline, load transducer 6 is equipped with in piston 5 ends of described cylinder, and described load transducer 6 connects electronics load display 7 by circuit.
Described cylinder 4 upper ends are bolted to connection scalable screw rod 9, the be threaded top center position of reaction frame 8 of described scalable screw rod 9.
Described electronics load display 7, baroswitch valve 3 all are arranged on the reaction frame 8.
The present invention compares with prior art, and whole device can well guarantee the stability of load, for the carrying of the static state in the ideal provides guarantee.According to the load of test needs, select the air pump of different ranges, by stable source of the gas, regulate air pressure and adjust load, and can continue guarantor year sample.Stable and equipment manufacturing cost cost of load and test duration cost are lower.The guarantor who is fit to very much above-mentioned standard is carried requirement and the similar test that has continuous guarantor to carry requirement.The static bearing test that can be widely used in all kinds of raised floors.
