Embodiment

[0051] as attached figure 1 to attach Figure 8 Shown:

[0052] The present invention provides a plate structure based on assembled steel heat insulation and smoke prevention air duct, including an outer metal layer 1;

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

[0054] The outer metal layer 1 includes:

[0055] Protrusion A101, the protrusion A101 is welded on the top surface of the outer metal layer 1 in a linear array, and the protrusion A101 has a semicircular arc structure, and the protrusion A101 forms the bending protection structure of the outer metal layer 1, so that the protrusion A101 The deformation protection ability of the outer metal layer 1 can be improved, and the protrusion A101 of the semicircular arc structure can reduce the weight;

[0056] The fixed structure 5 is installed on the outer metal layer 1 .

[0057] Reference as Figure 5 , the bottom surface of the outer metal layer 1 is provided with a gypsum layer 2, and the gypsum lay...

Abstract

The invention provides a plate structure based on assembly type steel heat insulation smoke prevention and exhaust air pipes, and relates to the technical field of smoke prevention and smoke exhaust of buildings. The problems that after existing devices are in butt joint to form a cylinder, the sealing performance of the butt joint position is weak, and the sealing performance of the butt joint position cannot be improved through structural improvement are solved. The plate structure based on the assembly type steel heat insulation smoke prevention and exhaust air pipes comprises an outer metal layer which is of an iron plate structure. A microporous foaming material layer is of a rectangular structure, the length of the microporous foaming material layer is larger than the lengths of the outer metal layer, a gypsum layer and an inner metal layer, and after the head end and the tail end of the outer metal layer are in butt joint and fastened, the head end and the tail end of the microporous foaming material layer are in elastic contact.

Description

technical field [0001] The invention belongs to the technical field of building smoke prevention and smoke exhaust, and more specifically relates to a plate structure based on an assembled steel heat insulation and smoke exhaust air duct. Background technique [0002] Air duct is a piping system used for air transportation and distribution. There are two types: composite air duct and inorganic air duct; as the name implies, the smoke exhaust duct is an air duct for smoke exhaust; this type of air duct needs to have strong heat insulation and Heat resistance. [0003] For example, the publication number: CN209851728U provides a steel refractory, heat-insulated and smoke-proof air duct plate, including an outer metal layer, a microporous foam material layer, an inorganic material layer and an inner metal layer stacked in sequence, and the inner metal layer and the inorganic material The layers are bonded by fireproof glue, and the inorganic material layer is one of gypsum boa...
