Abstract

The invention relates to a fire-resistant test device which is used for inspecting a single-layer framework. The device solves the problem that existing fire-resistant test furnaces cannot load architecture components and test the mechanical property and structural reaction of architecture components so that the fire-resistant design of architecture structure cannot be properly guided. The test device also comprises a reaction frame and two jacks; an outer furnace body consists four outside walls and takes the shape of a quadrangular prism; the inner furnace body consists of two inner walls and an inner furnace cover; the reaction frame is arranged outside the outer furnace; and the jacks are arranged under a beam of the reaction frame and connected with the lower surface of the beam. In the invention, the reaction frame and the jack are used for loading the test components so as to simulate real force of the test components; and the inner furnace is internally arranged in the outer furnace so that a fire hazard is only simulated between the inner furnace and the outer furnace, thus the testing aim is achieved and fuels can be saved by over 30 percent.

Description

technical field [0001] The invention relates to a fire resistance test device. Background technique [0002] Building fires in our country have always been serious, which is related to many factors such as our country's building structure, people's production characteristics, geographical location, and climatic conditions. In recent years, our country is in a period of severe fire situation, the number of building fires and losses are high, and there have been many large and major fires. Therefore, understanding the fire resistance of existing structures and improving the fire resistance of building structural components through reasonable design is an important topic in the field of building fire research. [0003] Fire resistance refers to how long a building can withstand a fire in a certain area without causing the fire to spread, and how long the structure can withstand a fire without being damaged. The main emphasis is on the fire resistance time, that is, the fire re...
