For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0020] A component that increases the sealing of the smoke and air duct, such as Figures 1 to 4 As shown, the smoke and air duct 1 is formed by crimping multiple sections of smoke and air duct from bottom to top, and is characterized in that a component is arranged in the smoke and air duct, and the component is fixed at the crimping gap 2 of the upper and lower sections of the smoke and air duct in the smoke and air duct. The component includes a baffle 3 and a hook 4. The hook 4 is fixed at the middle position of the baffle 3, and the hook 4 is hung on the top of the wall of the lower section of the smoke and air duct 5. The lower end of the wall of the upper section of the smoke and air duct 6 is pressed onto the top of the wall of the lower section of the smoke and air duct 5, and the hook 3 is fixed at the crimping gap 2 of the upper and lower sections of the smoke and air duct. The baffle 3 is fixed in the smoke and air duct 1, blocking the crimping gap of the upper and lower sections of the smoke and air duct.
[0021] In the existing installation of smoke and air ducts, the sealing of the gap 2 of the upper and lower smoke and air ducts is sealed with mortar seat slurry, which has a poor sealing effect and causes leakage or smoke leakage. The utility model adopts a baffle 3 fixed at the gap 2 of the upper and lower smoke and air ducts to first seal the gap of the upper and lower smoke and air ducts. The baffle 3 is equivalent to the role of the template in concrete pouring. In the prior art, there is no baffle 3 set in the structure of the gap 2 of the upper and lower smoke and air ducts, and it is impossible to use high-strength perfusion to perfuse and seal the gap of the upper and lower smoke and air ducts, because the high-strength perfusion slurry has high fluidity and is very easy to flow into the smoke and air duct through the gap of the upper and lower smoke and air ducts, resulting in the phenomenon of being unable to seal and wasting materials. The utility model adopts high-strength perfusion slurry to perfuse and seal the gap 2 of the upper and lower smoke and air ducts. Since the baffle 3 is equivalent to the role of the template, it blocks the high-strength perfusion slurry from flowing into the smoke and air duct. Therefore, the utility model has a good sealing effect, and the baffle 3 with a hook 4 has a simple structure, does not change the original installation method, and is simple to construct.
[0022] Example 1.
[0023] like Figures 1 to 4 As shown, the smoke and air duct 1 is a quadrilateral smoke and air duct, and the four components are respectively arranged at the crimping gaps 2 of the upper and lower sections of the smoke and air duct on the four sides of the smoke and air duct. The components include a baffle 3 and a hook 4. The hook 4 is fixed in the middle position of the baffle, and the hook 4 is hung on the top of the wall of each side of the lower section of the smoke and air duct 5. The lower end of the wall of each side of the upper section of the smoke and air duct 6 is pressed on the top of the wall of each side of the lower section of the smoke and air duct 5. The hook card 4 is fixed at the crimping gaps 2 of the upper and lower sections of the smoke and air duct on each side. The baffle 4 is fixed in the smoke and air duct 1, blocking the crimping gaps 2 of the upper and lower sections of the smoke and air duct on each side, and the intersection of the baffle 3 blocking the gaps 2 of the upper and lower sections of the smoke and air duct on each side is welded and fixed. Further, the hook 4 is welded and fixed in the middle position of the baffle 3, and the number of the hooks 4 welded and fixed on the baffle 3 is at least 2, and the baffle 3 is a galvanized steel plate. In this embodiment, the smoke and air duct is a square smoke and air duct that is most commonly used in current construction. In the square smoke and air duct, a baffle is fixed on each side by a hook, and the baffles on the four sides are connected to each other and the edges in contact are welded and fixedly connected, forming a gap-blocking structure at the gap between the upper and lower smoke and air ducts in the direction of the smoke and air duct. The hook 4 is welded and fixed to the middle position of the baffle 3, so that the upper and lower parts of the baffle 3 block the upper smoke and air duct 6 and the lower smoke and air duct 5 respectively. The baffle 3 is set in the smoke and air duct 1, so the material of the baffle 3 is selected from galvanized steel plate to prevent corrosion of the gas in the smoke and air duct 1.
[0024] Example 2
[0025] The smoke and air duct 1 is a circular smoke and air duct, the baffle 3 is a circular ring, and a plurality of hooks 4 are evenly spaced and fixed at the middle position of the outer surface of the circular ring. The plurality of hooks 4 are hung on the top of the wall of the lower section smoke and air duct 5, and the lower end of the wall of the upper section smoke and air duct 6 is pressed onto the top of the wall of the lower section smoke and air duct 5. The hooks 4 are fixed at the crimping gap 2 between the upper and lower sections of the smoke and air duct, and the circular ring is fixed in the smoke and air duct 1, blocking the crimping gap 2 between the upper and lower sections of the smoke and air duct. Further, the hooks 4 are welded and fixed at the middle position of the outer surface of the circular ring, and the number of hooks 4 welded and fixed on the circular ring is at least 4, and the preparation material of the circular ring is galvanized steel plate. In this embodiment, the smoke and air duct is a circular smoke and air duct that rarely appears during construction. In order to adapt to the circular smoke and air duct, the baffle 3 is made into a circular ring shape, and a plurality of hooks 4 are welded and fixed on the outer surface of the circular ring. In this embodiment, the number of hooks is 4, which are respectively welded and fixed at four symmetrical points in the middle position of the outer surface of the circular tube. The ring is closely attached to the inner wall of the circular smoke and air duct, so the diameter of the ring is smaller than the diameter of the circular smoke and air duct. The diameter of the ring is 1-2 mm smaller than the diameter of the circular smoke and air duct.
[0026] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
