Water spraying and cooling system for bearing test of free high-temperature compression member

Abstract

The invention relates to a water spraying and cooling system for a bearing test of a free high-temperature compression member. The water spraying and cooling system comprises metal supports arranged at the periphery of the compression member, wherein a lower fastening ring is arranged on the metal supports; the compression member is arranged at the central position of the lower fastening ring; the ring surface of the lower fastening ring is horizontal, and a plurality of free rocker arm assemblies are arranged on the ring surface at intervals; cooling water spraying nozzles are arranged at the overhanging ends of the free rocker arm assemblies; the spaces between water spraying heads of the cooling water spraying nozzles and the compression member are adjustable; and the cooling water spraying nozzles point to the center of the ring surface of the lower fastening ring and are obliquely arranged upwards. The water spraying and cooling system disclosed by the invention can be used for cooling a high-temperature cylindrical compression member and a high-temperature square compression member; cooling water uniformly distributes along the vertical wall surface, and the cooling effect is better; relative positions between the cooling water spraying nozzles and the compression member are controlled by using the free rocker arm assemblies, and the simplicity and the flexibility in operation are realized; the aim of meeting technical requirements of a cooling process test of the high-temperature square compression member is achieved; and in addition, the water spraying and cooling system has the advantages of simple structure, small size and convenience in disassembly and assembly.

Description

technical field [0001] The invention relates to the fields of structural engineering and fire science and technology, in particular to a water spray cooling system for a free-style high-temperature compression component bearing test. Background technique [0002] In recent years, with the rapid development of my country's construction industry, the problem of structural fire protection has become increasingly prominent, and it is necessary to conduct related research on the fire resistance performance of building structures. In the study of structural fire resistance, it is necessary to study the influence of the heating process on the load-bearing performance of the structure, as well as the destructive effect of the cooling process on the structure. There are various forms of compression members, including square members and cylindrical members. When testing the fire resistance of high-temperature components, it is necessary to ensure the cooling effect of the water spray...

AI Technical Summary

Problems solved by technology

The cooling water injection device temporarily installed on site has poor stability, and the water spray cooling system for bearing test of square high-temperature compression components and the water spray cooling system for bearing test of cylindrical high-temperature compression components have their own scope of application. The cooling effect of the components is poor, which cannot meet the technical requirements of the test, and sometimes produces a lot of waste of water resources
