A test device for fire resistance performance of building vertical partition members under water spray protection

Abstract

The invention discloses a fire resistance test device for a vertical building partition component in water-spraying protection. The fire resistance test device consists of a device body and smoke exhaust system, a fuel gas heating system, a water supply system, a water draining system, a data measurement and automatic control system, a video monitoring system and a computer, wherein the device body and smoke exhaust system comprises a furnace body, a flue, a chimney and a furnace door; the fuel gas heating system comprises a liquefied petroleum gas tank, a gasifier, an oil-water separator and a burner; the water supply system comprises a water pump, a valve and a spray head; the data measurement and automatic control system comprises a data acquisition controller, a thermocouple, a pressure sensor, a flow sensor, a differential pressure transmitter, a heat flow meter, a temperature controller, a flue regulator and a strain gauge. The fire resistance test device has the advantages as follows: through a unique structure, a water distribution difficulty of the fire resistance test device at high temperature is overcome for the first time in China; the fire resistance test device is safe, high in reliability and accurate in data measurement, can run continuously for a long time, and has a far-reaching guiding significance for a fire protection design technology and an engineering application technology of buildings in China.

Description

technical field [0001] The invention relates to a fire-resistant performance test device, in particular to a fire-resistant performance test device of a building vertical partition member under water spray protection. Background technique [0002] The fire resistance of building vertical partition members plays a vital role in the fire prevention and fire control of the whole building. When a fire breaks out, once the building's vertical partitions are burned through and damaged, the flames will spread rapidly, posing a major threat to the building structure and the safety of personnel and property. In recent years, a large number of super-large or high-rise modern public buildings have emerged in my country, such as gymnasiums, exhibition halls, theaters, hotels, airports, commercial plazas, etc. In order to adapt to the development trend of modern buildings with various forms and complex structures, and to meet the severe fire protection needs, many architectural design s...
