High-temperature cylindrical compression member test spray cooling system

Abstract

The invention relates to a high-temperature cylindrical compression member test spray cooling system, which comprises a metal support arranged around a cylindrical compression member, an annular secondary water distribution pipe is arranged on the metal support, the whole annular secondary water distribution pipe is of a ring-shaped structure matching the profile of the cylindrical compression member, the annulus of the annular secondary water distribution pipe is horizontal and is arranged coaxially with the cylindrical compression member, a plurality of cooling water nozzles are distributed at intervals along the circumference of the annular secondary water distribution pipe, and the spraying directions of the cooling water nozzles point to the center of the annulus of the annular secondary water distribution pipe and are obliquely upward. The operational stability of the high-temperature cylindrical compression member test spray cooling system is good, no straying and spattering phenomena of water flow occur in the process of a test, almost no deviating flow is produced along the circumferential surface of the cylindrical compression member, and therefore, the cooling effect on the high-temperature cylindrical compression member is good. The high-temperature cylindrical compression member test spray cooling system has the characteristics of simple overall structure, small size, light weight and flexibility and convenience in assembly and disassembly.

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 testing high-temperature cylindrical compression components. 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. According to relevant technical requirements, the water spray cooling process must ensure that the cooling water along the circumference of the outer surface of the cylinder should be evenly distributed. Due to the shape characteristics of the cylindrical compression member itself, the cooling water nozzle temporarily installed on site or the high-temperature cylindrical compression member bearing test cooling system, when the water spray pressure is too high...
