Combined type air exhausting channel and method for assembling the same

Abstract

The invention relates to an exhaust duct for buildings, in particular to a combined exhaust duct. The combined exhaust duct adopts the technical proposal that the combined exhaust duct comprises more than two exhaust duct plates (1) which are mutually matched and combined to form an integral single-section exhaust duct; and the single-section exhaust duct is firstly assembled, and then the whole exhaust duct is assembled according to requirements. Because the exhaust duct plates are combined into the exhaust duct, the exhaust duct plates can be transported to a construction site, the single-section exhaust duct does not need to be transported, the exhaust duct can be assembled on the construction site, and two sections of the exhaust ducts are combined through a convex-concave structure and then bonded by glue, so as to solve the connection problem; flatness error of the exhaust duct is not more than 1 to 3 millimeters, and exposed parts do not need to be plastered; and when the exhaust duct is carried and installed, the exhaust duct does not break nor lose corners, reduces cost, and saves materials and manpower. The exhaust duct has the characteristics of reasonable structure, convenient installation, no breakage, easy processing of connection and the like, does not need to transport the single-section exhaust duct, only needs to transport the exhaust duct plates, and can improve transportation volume and reduce cost.

Description

Technical field: [0001] The invention relates to an air exhaust channel for building buildings and a method for making the air exhaust channel, in particular to a combined air exhaust channel and an assembly method for the air exhaust channel. Background technique: [0002] At present, the exhaust air ducts commonly used by people in building houses are all integral. Generally, semi-finished products are made of cement mortar through templates, that is, single-section air exhaust ducts, cuboid, and cylindrical. When the air duct is connected, the connection (joint stubble) should be treated with iron hoops, which is complicated and difficult to construct; because the surface flatness and verticality of the semi-finished air duct are difficult to meet the quality requirements, the exposed part of the air duct needs to be plastered during installation Treatment; for high-rise buildings, very long exhaust ducts are needed, and the problem of stubble between semi-finished exhaus...

[0002] At present, the exhaust air ducts commonly used by people in building houses are all integrated. Generally, semi-finished products are made of cement mortar through templates, that is, single-section air exhaust ducts, cuboid, and cylindrical. To connect the air ducts, the joints (joint stubble) should be treated with iron hoops, which is complex and difficult to construct; because the surface flatness and verticality of the semi-finished air ducts are difficult to meet the quality requirements, the exposed parts of the air ducts need to be plastered during installation Treatment; for high-rise buildings, long exhaust ducts are required, and the problem of stubble between semi-finished exhaust ducts is difficult to deal with

In addition, in the process of transportation and installation, the single-section exhaust duct is not only inconvenient to transport, but also easily bumped and damaged, resulting in breakage and corner drop, resulting in waste
