Embodiment

[0017] Embodiment: A kind of technique of combining air duct with strapping, as figure 1 As shown, the steps of the process are: Step 1, making the air duct plate; Step 2, cutting the air duct plate; Step 3, bonding the air duct. The bonding process of the air duct is as follows: place four straps 5 that are roughly evenly arranged on the bearing surface, and place the downwind duct plate 1 flat on the straps 5; then glue the left and right air duct plates to the downwind Both sides of the tube plate (the bonding edge of the left and right air duct plates are coated with adhesive in advance), and then the upper air duct plate 3 is glued between the two air duct plates (the lower air duct plate 1 and the upper air duct plate 1 The end of the tube plate 3 is misplaced with the left and right air tube plates 4, such as Figure 4 shown); tie the strapping 5 along the transverse direction of each air duct plate; after the adhesive is cured, remove the strapping 5.

Abstract

The invention relates to a technology to combine air duct by using strapping. Its steps are: 1. preparation of air duct plate. 2. Incision of air duct plate. 3. Adhesion of air duct plate. The workingprocedures of adhesion are: a. put complex strapping on the bearing surface and put the lower air duct plate on them horizontally. b. Agglutinate the left and right air duct plates on both sides of the lower plate and glue the upper plate between them. c. Pack the strapping along the lateral direction of each plate. d. Remove the strapping after the adhesive is solidified. The advantages of thisinvention are: 1. using strapping to fix each air duct plate during their adhering and solidifying can avoid distortion between adjacent plates and assure the bonding points of the four plates close and have good sealing. 2. The air duct plates made by this technology have large faying surfaces, accurate positioning, high intensity and convenient installation and application.

Description

【Technical field】 [0001] The invention relates to a production process of ventilation ducts for buildings, in particular to a process for combining air ducts with binding tapes. 【Background technique】 [0002] The combination process of phenolic foam board air ducts, polyurethane foam board air ducts, and glass fiber board air ducts currently on the market is: four grooves are opened in one air duct board, and the depth of each groove is equal to the thickness of the insulation material. Disassemble and assemble the air duct plate at each groove, and the insulation material in the air duct plate is covered with a layer of glass fiber aluminum foil to connect the four air duct plates, and the joints at both ends of the air duct plate are glued with aluminum foil tape , to form an air duct, at this time the original four grooves are also formed as connecting seams between adjacent air duct plates. There are large joints in this type of ventilation duct, and it is easy to gene...
