Plate structure based on assembly type steel heat insulation smoke prevention and exhaust air pipe

Abstract

The invention discloses a plate structure based on an assembly type steel heat insulation smoke prevention and exhaust air pipe. The plate structure comprises a mounting plate frame, assembly mechanisms and an air pipe plate, the air pipe plate is arranged in the mounting plate frame, the assembly mechanisms are arranged in the middle of one side of the inner wall of the mounting plate frame and the middle of one side of the periphery of the air pipe plate, the periphery of the air pipe plate is sleeved with a spiral air inducing pipe, and the two ends of the spiral air inducing pipe are both communicated with the air pipe plate. The spiral air inducing pipes are arranged on the periphery of the air pipe plate, and the spiral air inducing pipes are positioned through clamping pieces and top fixing pieces, so that the internal circulation effect can be achieved in the air pipe plate by means of the guiding effect of the multiple sets of induced draft fans when smoke exhaust airflow carries out conveying and drainage in the air pipe plate structure; and therefore, the effect that the internal airflow of the air pipe plate structure continuously keeps active is effectively achieved, the problem that dirt is easily formed due to smoke accumulation is effectively solved, and the smoke exhaust efficiency of the smoke exhaust air pipe plate structure is effectively improved.

Description

technical field [0001] The invention relates to the technical field of air duct plate structures, in particular to an assembled steel heat-insulating and smoke-proof air duct plate structure. Background technique [0002] The smoke prevention and exhaust system is composed of supply and exhaust ducts, pipe wells, fire dampers, door switch equipment, supply and exhaust fans and other equipment. The smoke prevention system is set in the form of positive pressure in the stairwell. The smoke exhaust volume of the mechanical smoke exhaust system is directly related to the smoke prevention zone. The smoke prevention facilities of high-rise buildings should be divided into the smoke prevention facilities of mechanical pressurized air supply and the natural smoke exhaust facilities of opening the external windows. [0003] Duct is a system of piping used for the conveyance and distribution of air. There are two kinds of composite air duct and inorganic air duct. Composite air du...
