Embodiment

[0051] as attached figure 1 to the attached Figure 8 shown:

[0052] The present invention provides a plate structure based on an assembled steel heat-insulating, smoke-proof, and exhaust air duct, comprising an outer metal layer 1;

[0053] The outer metal layer 1 is an iron plate structure;

[0054] The outer metal layer 1 includes:

[0055] The protrusions A101 are welded on the top surface of the outer metal layer 1 in a linear array, and the protrusions A101 are semi-circular arc structures, and the protrusions A101 form the bending protection structure of the outer metal layer 1, so that the protrusions A101 The deformation protection ability of the outer metal layer 1 can be improved, and the protrusion A101 of the semi-circular arc structure can reduce the weight;

[0056] The fixing structure 5 is mounted on the outer metal layer 1 .

[0057] refer to as Figure 5 The bottom end surface of the outer metal layer 1 is provided with a gypsum layer 2, and the gypsum ...

Abstract

The invention provides an assembled steel heat insulation and smoke prevention air pipe plate structure, relates to the technical field of building smoke prevention and smoke exhaust, and solves the problem that the sealing performance of the butt joint of the existing device is weak after it is butted into a cylindrical shape, and cannot pass through Structural improvement improves the sealing performance of the joint. An assembled steel heat-insulating and smoke-proof air duct plate structure includes an outer metal layer; the outer metal layer is an iron plate structure. The microporous foam material layer has a rectangular structure, and the length of the microporous foam material layer is greater than the length of the outer metal layer, the gypsum layer and the inner metal layer, and when the head end and the tail end of the outer metal layer are butted and fastened The head end and tail end of the microporous foam material layer are in elastic contact shape.

Description

technical field [0001] The invention belongs to the technical field of building smoke prevention and exhaust, and more particularly, particularly relates to a sheet structure based on an assembled steel heat insulation and smoke prevention and exhaust air duct. Background technique [0002] Air duct is a duct system used for air transportation and distribution. There are two types of composite air ducts and inorganic air ducts; smoke exhaust air ducts, as the name suggests, are air ducts for smoke exhaust; such air ducts require strong thermal insulation and Heat resistance. [0003] For example, publication number: CN209851728U provides a steel refractory, heat-insulating, smoke-proof and exhaust-proof air duct plate, comprising an outer metal layer, a microporous foam material layer, an inorganic material layer, and an inner metal layer that are stacked in sequence, and the inner metal layer and the inorganic material are stacked in sequence. The layers are bonded by fire...
