Problems solved by technology

[0002] Fire barrier structures need to meet the fire resistance performance requirements specified in the standard. The size of the traditional detection device is too large, which is not conducive to carrying out research experiments and is only used for standard tests.
The function of the device is single, and it can only do horizontal component testing or vertical component testing alone, and cannot realize the dual-purpose function of horizontal-vertical component testing
The temperature control and heat preservation performance in the furnace is not enough, the temperature rise cannot meet the requirements of the tunnel temperature rise curve, and the experiment cost is too high

Abstract

The invention discloses an experiment device for the fire resistance of a structure. A furnace body adopts a vertical and horizontal dual-use design. When a vertical furnace door is closed, testing onhorizontal components (such as a floor and a ceiling) can be conducted by opening a horizontal furnace door; and when the horizontal furnace door is closed, testing on vertical components (such as doors and walls) can be conducted by opening the vertical furnace door. The furnace body provides a temperature sensor, pressure sensors and an oxygen content detection connector, and changes of the temperature, the pressure and the oxygen content in the furnace can be detected in real time. In addition, the thermal insulation performance in the furnace is excellent, the temperature in the furnace can linearly rise to 1,200 DEG C within 5 min under control of a program, and after being kept for a period of time, the temperature linearly drops to room temperature.

Description

technical field [0001] The invention relates to the technical field of fire-resistant experiments, in particular to a structural fire-resistant experimental device, which is used for testing the fire-resistant performance of structures. Background technique [0002] Fire barrier structures need to meet the fire resistance performance requirements specified in the standard. The size of the traditional detection device is too large, which is not conducive to carrying out research experiments and is only used for standard tests. The device has a single function, and can only be used for horizontal component testing or vertical component testing alone, and cannot realize the dual-purpose function of horizontal-vertical component testing. The temperature control and heat preservation performance in the furnace is not enough, the temperature rise cannot meet the requirements of the tunnel temperature rise curve, and the experiment cost is too high.
