The production method of the galvanized sheet common flange air pipe comprises the following specific steps:
firstly, manufacturing an air duct sketch according to manufacturing requirements, drawing a processing sketch according to a system served by an air duct according to a construction drawing and actual field conditions (air duct elevation, trend and other professional coordination conditions), numbering according to the system, and carrying out datamation on the manufacturing process of the air duct through corresponding data;
step two, preparing a single straight pipe air pipe according to an air pipe sketch, and flanging the edge of the prepared single straight pipe air pipe to form a flange structure for connecting with an adjacent single air pipe;
step three, as with the single straight pipe air duct, preparing a single special pipe air duct according to an air duct sketch, such as a single air duct for special positions or special functions, such as elbows, tees, reducing joints, cross joints, plugs and the like;
and fourthly, fixing flange corners with flange edges 42 formed by turned-over edges at the edges of the air pipes, and fixing one flange corner 41 at each of the four corners so as to form a complete flange structure, as shown in fig. 4, assembling and fixing one or more single straight pipe air pipes and one or more single special pipe air pipes by fixing adjacent flange structures so as to form a galvanized plate common plate flange air pipe, wherein the two single air pipes can be further reinforced by adopting flange fixing clamps for the purpose of further reinforcing the stability of the two single air pipes.
The air pipe is flanged, the weight of the air pipe is reduced, flange section steel and connecting bolts are saved compared with the traditional angle iron flange, and material loss is reduced.
Selecting a galvanized sheet with a smooth surface and without serious scratch and corrosion of a cold-rolled sheet, and preventing angle steel from being seriously rusted and deformed; the preparation method of the single straight pipe air pipe comprises the following steps:
a1, cutting corners and shearing plates of the galvanized plates according to draft information of the air ducts, and numbering according to the draft information;
step A2, the cut galvanized sheet is engaged and assembled to form a closed tubular structure, and a main body part of the single air duct is constructed;
and step A3, bending and flanging the edge outwards to form a flange structure, and forming the single straight pipe air pipe.
When the method is adopted for preparing the single air duct, when the large side of the air duct is larger than 630mm, the air duct needs to be reinforced in order to increase the stability of the air duct, when the large side of the air duct is 630-1000mm, step A0 is arranged before step A1, the galvanized sheet is ribbed, as shown in figure 1, the arrangement is regular, the intervals are uniform, the sheet surface is not deformed obviously, and then the ribbed or galvanized sheet with Z-shaped grooves is cut; when the size of the large side of the air pipe is larger than 1000mm, after the step A3, the step A4 is carried out, the outer side of the manufactured single air pipe is reinforced, angle steel 2, flat steel and steel pipes are adopted for reinforcement, as shown in figure 2, or a reinforcing frame 3 is prepared, as shown in figure 3, the reinforcing frame is fixedly sleeved on the outer side of the single air pipe to realize the reinforcing effect, or a harness cord screw is additionally arranged for reinforcing the air pipe, wherein the height of the angle steel, the flat steel, the steel pipes, the Z-shaped grooves or the press ribs is smaller than the height of the flange structure, the arrangement is orderly, the intervals are uniformly symmetrical and are not larger than 220mm, and the riveting with the air pipe is firm; when the section of the air duct is larger than 1250mm multiplied by 630mm, in order to keep the adjacent wall surfaces vertical to each other, the four corners in the air duct are reinforced by adopting 90-degree inclined supports. In addition, the internal reinforcement can be carried out by adopting a harness cord screw. When the length of the medium-pressure and high-pressure system air pipe is more than 1250mm, a reinforcing frame is adopted for reinforcing, and a reinforcing or reinforcing measure for preventing the expansion crack of a single seaming seam of the high-pressure system air pipe is also required.
Similar to the preparation process of the single air duct, the preparation method of the single special-shaped air duct comprises the following steps:
step B1, cutting a semi-finished product from the galvanized sheet according to the draft of the air duct, and numbering according to the draft information;
step B2, performing seaming assembly on the semi-finished galvanized plate to form a closed tubular structure, and constructing a main body part of the single air duct;
and step B3, bending and flanging the edge to form a flange structure, and forming the special pipe, the straight pipe and the air pipe.
Because the air duct production line and the construction site cannot be in the same place, the air duct production line and the construction site are processed into semi-finished products according to drawn sketches in a workshop, numbered according to a system, and assembled according to the serial numbers on the site.
The four L-shaped flange angles are respectively inserted into the outward flanging structures adjacent to the single straight pipe air pipe or the single special-shaped air pipe, embedded into the flanging by hammering and fixed through bolts, so that a complete flange structure is formed and used for connection. The branch pipe and the main pipe can be connected or riveted with the main pipe by a joint seam or a rivet for the reverse side; the connection between the main pipes is fixed by bolts to contact the flange angle. When the size of the large side of the air pipe exceeds 450mm, fixing clips are mounted on the two connected turned sides; the side length of the air pipe is 0-200mm, a flange fixing clip is not required to be installed, the side length of the air pipe is 200-550mm, a flange fixing clip is installed in the middle of the air pipe, two flange fixing clips are installed at the same distance of 1000mm and the air pipe is 550-1000mm, and a flange fixing clip is installed at each distance of 250mm when the air pipe length exceeds 1000 mm.
In order to ensure the transmission function of the air pipe, the air pipe needs to be sealed, the joints of the flange corners and the branch pipes and the main pipe are sealed, the joints of the bolts are sealed, as shown in fig. 5, the adjacent flange corners are connected through connecting bolts 52, and a sealing strip 51 is arranged between the two flanges. Sealing the low-pressure air pipe to a position 40-50 mm inside the pipe at the folding position of the air pipe joint part; the high-pressure air pipe is also sealed at the longitudinal bite of the air pipe and the composite part of the air pipe. The flange seal is preferably mounted adjacent the outer side of the flange or intermediate the flanges. When the flange sealing strips are overlapped on the flange end faces, the overlapping is about 30-40 mm. The joint of 4 flange angles of the flange of the common-plate flange air pipe needs to be sealed and leak-proof by glass cement, the joint seaming is required to be sealed and leak-proof by glass cement at a position 80mm downward from the flange angle, and the sealant is arranged on the positive pressure side of the air pipe.
