Abstract

The invention relates to a fire-resistance testing device, in particular to a fire-resistance testing device used for a restrained beam. The invention aims at solving the problem that the existing testing device can not test the fire-resistance performance of the restrained beam. Two sample supporters are longitudinally arranged on the ground surface; two reaction frames are positively arranged on the ground surface at the external side of the two sample supporters; a restraining steel column is vertically arranged on a rolling shaft; a tension-compression sensor is arranged between the reaction frame and the restraining steel column; a furnace body is arranged on the ground surface between the two sample supporters; two anchor rods on a vertical-loading device are transversely arranged at two sides of the furnace body; a jack and a weighing sensor are respectively arranged at the upper part and the lower part of the lower surface of a reaction steel beam; a nozzle is arranged at a sprout; an oil pump is connected with the nozzle; the oil pump is connected with an oil tank; a fan is communicated with the sprout; the furnace body is provided with a flue; the thermocouple is arranged on the furnace body wall; in the invention, the testing device is provided for the fire-resistance test of the restrained beam, and the test requirements required by the test such as temperature increment, boundary constrains, reaction measurement, loading, and the like are met.

Description

technical field [0001] The invention relates to a fire resistance test device. Background technique [0002] Fire is a hazard caused by uncontrolled burning, and it is also a disaster faced by mankind. It can ruthlessly take away the precious lives of many people, and can reduce the wealth created by mankind for many years to ashes in an instant. Fires can be mainly divided into building fires, forest fires, industrial and mining fires, and transportation fires. Among them, building fires are the most direct and serious harm to people, because various types of buildings are the main places for people's life and production activities, and they are also places where property is highly concentrated. One of the most important issues that should be considered when dealing with The beam is the main horizontal load-bearing component of the building. Its main task is to bear the load from the floor and transfer the load to the column at the same time. In actual engineering, as a ...
