Problems solved by technology

However, in reality, the test piece must bear the load while heating up, so the current test mode cannot simulate the mechanical properties of the test piece well under the real high temperature condition.

Abstract

The invention discloses a full-size vertical component high temperature loading system. The system comprises a counterforce frame, a conversion beam, a triangular steel frame column, angle braces, a slide beam, a groove plate and a pier. The counterforce frame and the conversion beam are connected through a bolt. The conversion beam and the triangular steel frame column are connected through the bolt, and two sides are erected with the angle braces. A reinforcing steel bar is welded on one side of the triangular steel frame column and is taken as a guide rail system, and the slide beam and thetriangular steel frame column are connected through a pulley. The slide beam is connected to an upper end groove plate by the bolt. A lower end groove plate is connected to the pier through the bolt.By using the full-size vertical component high temperature loading system, a vertical component is at a high temperature under fire and loads pressure whose a maximum value is 1000 tons at the same time, and a loading position is not limited to the position of the counterforce frame so as to realize matched usage of a furnace and a loading device.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a loading system, in particular to a high-temperature loading system for full-scale vertical components. Background technique [0002] Generally speaking, under the action of fire and high temperature, the mechanical properties of structural materials will be attenuated to a certain extent, resulting in a decrease in the bearing capacity of structures and components at high temperatures, and eventually, certain damage or even collapse of the structure. On September 11, 2001, the World Trade Center in the United States broke out in a serious fire after being hit by an airplane. The main structure collapsed under the high temperature of the fire, eventually killing about 2,998 people. Similar serious building fire cases have occurred frequently. Therefore, the high temperature loading test of the specimen is of great significance to the structural design. [0003] In the current expe...
