[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-4 As shown, an integrated smoke control, exhaust, and insulation duct includes:

[0034] Example 1

[0035] This embodiment provides an inner tube 2 disposed inside the outer tube 1, and the two tubes (outer tube 1 and inner tube 2) maintain a predetermined distance to form an indentation groove 3; the non-combustible thermal insulation filler 4 is inserted into the indentation groove 3. In short, the welding of the outer tube 1 and the inner tube 2 is completed in advance, and then the stamped non-combustible thermal insulation filler 4 is inserted into the indentation groove 3.

[0036] Furthermore, the density of the non-combustible thermal insulation filler 4 in the above embodiment is 100 kg / m³. 3 Its density is 100 kg / m³ 3The whole thickness is 25mm-35mm. The wall thickness of the outer tube 1 and the inner tube 2 is 0.35-0.5mm. The thin shell design of the outer tube 1 and the inner tube 2 greatly reduces the weight of the whole air duct. Compared with the traditional, the high-density fireproof material is used as the outer tube 1 and the inner tube 2 sandwich material, so whether it is a fire outside the air duct or a fire inside the air duct, the non-combustible insulation filling body 4 will play a role, and the outer tube 1 or the inner tube 2 will be insulated, and the shape will be maintained.

[0037] The non-combustible insulation filling body 4 in the above embodiment can be A-grade non-combustible material such as glass wool board, foamed cement board or foamed ceramic board, or B-grade non-combustible material such as polystyrene board, extruded board, phenolic board, polyurethane board, or other flame-retardant materials known to those skilled in the art.

[0038] Further, the outer tube 1 and the inner tube 2 are at least any one of color steel plate, galvanized steel plate or aluminum-zinc plated steel plate.

[0039] In the above technology, the space between the outer tube 1 and the inner tube 2 is increased by the non-combustible insulation filling body 4, and the double-layer steel design is adopted so that when a fire occurs, the outer tube 1 or the inner tube 2 is blocked by the non-combustible insulation filling body 4, and the shape of the outer tube 1 or the inner tube 2 is maintained within 2 hours or more after the fire occurs, and will not be deformed due to high temperature.

[0040] Example two

[0041] Based on example one, the present example provides an optimal embodiment, and the non-combustible insulation filling body 4 is specifically rock wool. That is, a whole rock wool body is embedded in the pre-punched entry type groove 3. Rock wool, a material made from natural basalt through high-temperature melting and fiberization, has an impressive fire resistance temperature. Usually, the fire resistance temperature of rock wool can be above 1000℃. This means that during a fire, rock wool can withstand high temperature for a long time, effectively preventing the spread of fire, thereby protecting the shape of the air duct material during the fire for a long time, and achieving the predetermined standard.

[0042] Example three

[0043] Based on the second embodiment, the present example provides another optimal embodiment, the non-combustible thermal insulation filling body 4 is composed of not less than three layers of rock wool laminated stamping, and each layer of rock wool layer is composed of a linear array of rock wool blocks, and the specification of the rock wool block is 500mm*600mm. The non-combustible thermal insulation filling body 4 is formed by laminated stamping. Because a multi-layer structure is adopted, the fire resistance property is increased. In short, when a fire occurs, one layer of rock wool layer will first contact high temperature, and with the high temperature, the rock wool layer absorbs heat and falls off, at this time, the second layer of rock wool layer continues to play a role, and so on for the last layer of rock wool layer. Thus, the shape retention time of the air pipe in the fire is greatly increased.

[0044] Embodiment four

[0045] Based on the third embodiment, the present embodiment provides another optimal embodiment, the non-combustible thermal insulation filling body 4 is composed of not less than three layers of rock wool laminated stamping, and the multiple layers of laminated rock wool are distributed in an interleaved manner (such as Figure 4 ), and the rock wool layer is arranged in a horizontal plane, and then one rock wool block of the upper and lower layers of rock wool layers corresponds to the center of the next layer of rock wool block, that is, the interleaved distribution.

[0046] The design of the multiple layers of laminated stamping and interleaved distribution of the rock wool layer further enhances the thickness and density of the fireproof barrier, and the structure of the multiple layers of laminated stamping and interleaved distribution can further reduce the heat transfer, so that it is more difficult for the flame to penetrate. And when a fire occurs, the structure of the multiple layers of laminated stamping and interleaved distribution of the rock wool layer can form a heat insulation wall to delay the spread speed of the fire. Secondly, when a fire occurs, the structure of the multiple layers of laminated stamping and interleaved distribution of the rock wool layer can form a heat insulation wall to delay the spread speed of the fire.

[0047] Embodiment five

[0048] On the basis of the above-mentioned first embodiment, the present embodiment aims to provide the design structure of the air pipe, that is, the smoke exhaust duct.

[0049] The stamping non-combustible thermal insulation filling body 4 is inserted between the outer ring pipe body 1 and the inner ring pipe body 2 to form the air pipe main body. After completion, the assembly of the combined flange sealing frame 5 is carried out, which is fixedly installed in the port at both ends of the air pipe main body.

[0050] Further, in combination with Figure 3 It can be seen that the combined flange sealing frame 5 in the embodiment is divided into corner combining parts 51 and horizontal strip sheet metal parts 52 according to the structure, wherein:

[0051] The back surface of the horizontal strip sheet metal part 52 is symmetrically provided with a plug 521, and each plug 521 is inserted between the pipe body and the non-combustible thermal insulation filling body 4;

[0052] The corner connecting piece 51 is provided with an insertion part 511 adjacent to two side edges, and the insertion part 511 is inserted into the slot of the port of the horizontal strip metal piece 52 to be integrated.

[0053] The back of the corner connecting piece 51 is also provided with a triangular insertion plate 512, that is, a channel steel, which is directly inserted between the top corner of the outer tube body 1 and the non-combustible heat insulation filling body 4.

[0054] It should be noted that the insertion part 511 in the above embodiment is specifically two symmetrically distributed rectangular blocks.

[0055] In the above technology, the combination type flange sealing frame 5 is clamped between the outer tube body 1 and the inner tube body 2 in an inlaying manner, and the production of the air pipe, that is, the exhaust pipe, can be completed by spot welding or stamping, thereby greatly reducing the production process of the entire exhaust pipe and reducing the production cost.

[0056] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the present application.
