[0045] The present invention provides a method for assembling and disassembling a detachable heat-insulating shed, which is applied to the aforementioned detachable heat-insulating shed, and includes an installation method and a disassembly method;

[0046] The installation method includes the following steps:

[0047] (1) Install column 5: Column 5 is made of square tube welded to the base plate and fixed to the ground concrete by anchor bolt 8. After the column 5 is installed, the tie rod assembly is connected to the equipment in the shed.

[0048] (2) Install roof assembly 1: Connect the upper end of the purlin frame of roof assembly 1 to the ear plate on the purlin frame 2 with bolts 8, and connect the lower end of the purlin frame to the connecting plate on the column 5 with bolts 8. Lift the purlin frame 2 by the lifting ear plate 15 welded on the purlin frame 2.

[0049] (3) Install wall panels and pipe fittings: Push the insulation wall panel 4 and insulation door 3 into the column 5 and close them to the angle steel 18. Fix them on the column 5 with double pressure plate 6 and single pressure plate 7. After installing the pipe fittings of each pipe, install the pipe fittings on the pipeline, push the insulation wall panel 4 into the pipeline and use sealant to firmly bond the pipe fittings.

[0050] (4) Welding angle steel 18: When welding angle steel 18 to column 5, the flatness error of angle steel 18 on both sides is less than or equal to 2mm, and the weld height is less than or equal to 3mm. It is required that there are no weld scars after welding.

[0051] (5) Gap sealing: After all components are installed, all gaps in the insulation shed are sealed with foam sealant.

[0052] (6) Install the wind-resistant ropes: After sealing, select the appropriate safety factor of the wind-resistant ropes according to the environmental requirements and install the wind-resistant ropes on the insulation shed.

[0053] The method for disassembling the heat-insulating shed of the present invention is as follows:

[0054] Perform the following steps in sequence: 1. Remove the wind-loaded tension ropes; 2. Remove the purlin frame; 3. Remove the tie rods and their shear supports; 4. Remove the insulated door; 5. Remove the pipe inserts; 6. Remove the insulated wall panels; 7. Remove the columns.

[0055] In step (1), the anchor bolts 8 are M20×600mm, and the columns 5 are uniformly numbered so that the position of the columns 5 corresponds one-to-one with the pre-installation position.

[0056] The explosion-proof exhaust fan 10 and the self-blowing louver 16 are pre-installed and fixed on the corresponding components, and are installed and removed together with the components.

[0057] Using the purlin frame 2, an electric hoist is used as a hoisting device to place and adjust the equipment inside the shed, and the pipes of each piece of equipment in the shed are installed on the insulation wall panel 4 of the shed.
