Problems solved by technology

[0003] However, there are several problems in the test process: (1) During the process of moving the test model, damage to the model and residual deformation may be caused; (2) The conventional fire test furnace can only be used for the test of component specimens, and cannot be used for multi-layer frames The test of the overall structure, and the test of a certain layer of the multi-layer frame cannot be carried out; (3) the size of the test furnace is fixed, which limits the size of the test model; (5) The traditional method of a

Embodiment approach

[0091] This embodiment also provides an implementation method of a cascaded high-energy earthquake-fire coupling test system, taking the component "pseudo-static-fire" coupling test as an example, specifically including the following steps:

[0092] 1) Hoist the test piece into the self-balancing loading system, loosen the anchor bolts of the anchor steel beam 84, and raise each walking jacking cylinder 853 synchronously. After the walking jacking cylinder 853 is raised to the predetermined position, the steel beam walking device The frame pulley block 854 of 85 moves along the first track 5, and moves the two movable reaction force frames 8 to appropriate positions according to the size of the test piece;

[0093] 2) Loosen the connection between the frame main beam 83 and the H-shaped steel column 81, drive the column lifting cylinder 9 to adjust the high-temperature self-sensing loading beam 1 to the specified height, and drive the actuator 7 to make the high-temperature sel...

Abstract

The invention discloses a cascade high-energy earthquake-fire coupling test system which comprises a self-balancing loading system, a lifting furnace system and a smoke collecting hood system which is erected at the upper end of the lifting furnace system and can collect smoke. The self-balancing loading system comprises two movable counterforce frames capable of walking on a first track and a high-temperature self-sensing loading beam erected at the tops of the two movable counterforce frames; the lifting furnace system comprises a furnace body mounting frame internally provided with a combined furnace body in a hoisting manner and capable of walking on a second track, the upper end of the furnace body mounting frame is slidably connected with two movable beams, the lower end faces of the movable beams are provided with movable winches, and operation devices are hoisted at the bottoms of the movable winches. The system can meet different earthquake-fire coupling test requirements.

Description

technical field [0001] The invention relates to the technical field of fire or earthquake-fire coupling, in particular to a cascade high-energy earthquake-fire coupling test system. Background technique [0002] At present, research on the mechanism and prevention and control of multi-disaster coupling disasters has become a major national demand. Among them, earthquakes and fires are the most frequent coupling disasters, which may lead to major accidents and disasters. At present, the main steps of earthquake-fire coupling test in China are to conduct earthquake simulation shaking table test first, and then move the model to the fire test furnace for fire test after the earthquake simulation shaking table test is completed. [0003] However, there are several problems in the test process: (1) During the process of moving the test model, damage to the model and residual deformation may be caused; (2) The conventional fire test furnace can only be used for the test of compone...
