Movable reaction support adopting water cooling as well as method

Abstract

The invention belongs to the technical field of a fire experiment furnace, and particularly relates to a movable reaction support adopting water cooling at the bottom of the fire experiment furnace as well as a production method of the movable reaction support. Water is injected into a groove of channel steel, is taken as a heating medium and can reduce the temperature of an outer surface after evaporation, so that the problem of over high temperature of the outer surface of shape steel in the bottom support position in a fire experiment can be effectively solved, further, the shape steel is adopted to replace steel bars and criss-cross support plates are arranged in the support, accordingly, the bearing capacity of the bottom support is further improved, and the service life of the shape steel is prolonged by reducing the temperature of the outer surface of the shape steel; meanwhile, the condition that a worker is scalded by carelessly contacting with the shape steel of the bottom support in the experiment can be avoided; the movable reaction support can be used separately or in a combined manner aiming at a test object, is simple, practical, economical, reasonable, convenient to transport and easy to operate and can be widely applied to a building component fire resistance test in a fire laboratory.

Description

technical field [0001] The invention belongs to the technical field of fire experiment furnaces, in particular to a movable reaction force experiment support for water cooling at the bottom of a fire experiment furnace and a manufacturing method thereof. Background technique [0002] Building components mainly include floor slabs, long-span beams, I-beams, columns, interior and exterior wall panels, doors, windows, and suspended ceilings. The fire resistance test of building components is mainly to study the development process of indoor fire temperature and investigate the temperature field and structural mechanical properties inside building components, so as to provide a basis for the fire resistance design of building components and the damage assessment and repair of structures after fire. Reinforcement provides a scientific basis. At present, the increasing number of building fires, especially after the "911" incident, has made people pay more and more attention to th...

Problems solved by technology

[0005] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a method that can reduce the temperature of the outer surface after evaporation of water as the heating medium, and use section steel instead of steel bars to increase the bearing capacity of the support, thereby solving the problem of the bearing capacity of the bottom support. Insufficient force; this technology is economical and applicable, and is convenient for transportation. When in use, it can be used alone or in parallel, and it is easy to operate and has a significant effect. Water cooling movable reaction force support and its manufacturing method
