Problems solved by technology

[0002] At present, most houses use square pipes prefabricated with cement, magnesium oxychloride, lime and other cementitious materials to realize smoke exhaust and ventilation. When using them, the entire surface must be plastered, otherwise there will be certain technical difficulties when connecting with the wall. , the connection is not firm, and there is a phenomenon of through cracks at the connection; the accessories such as the reverse valve, the reverse plate and the exhaust hole must be installed in advance, and it is difficult to realize mechanization; after the pipe is made, it can only be used for smoke exhaust replacement gas, it is difficult to convert it into a shared house

example 1

[0026] Such as figure 1 As shown, this type of groove is composed of a groove body A1 and an inlay edge 2. The groove body A1 is a cylindrical body or a table-shaped body with two opposite sides that are not connected but connected at both ends. The inlay edge 2 is formed on the opposite sides of the groove body A1. The outwardly extending edge designed at the outer corner of the edge; the inlaid edge 2 is provided with several through holes A3. The inlay edge 2 is designed to have the same thickness from inside to outside.

example 2

[0028] Such as figure 2 As shown, the type groove is only composed of the groove body A1, and several through holes B8 are arranged at the edge of the groove body A1. A reinforcing rib B7 parallel to the axial direction of the tank A1 is provided on the inner wall or the outer wall of the tank A1 .

example 3

[0030] Such as image 3 As shown, several holes B9 are provided at the edge of the tank A1.

Abstract

The invention discloses a molding groove for exhausting smoke, exchanging air and covering a pipeline. The molding groove comprises a groove body A and embedding edges, wherein the groove body A is a columnar body or a platform-shaped body, the two opposite edges are not butted, and the two ends are not sealed; the embedding edges are edges which are designed at the outer corners of the two opposite edges of the groove body A and extend outwards; and the embedding edges are provided with a plurality of through holes A. The molding groove disclosed by the invention has the beneficial effects that the mechanical degree is high, the materials are saved, the use space of a house is saved, facilities such as a reversing valve are conveniently installed in any time, the safe connection with other objects can be realized and multiple purposes with one groove also can be achieved.

Description

technical field [0001] The invention relates to a type groove for exhausting smoke and ventilating and covering pipelines. Background technique [0002] At present, most houses use square pipes prefabricated with cement, magnesium oxychloride, lime and other cementitious materials to realize smoke exhaust and ventilation. When using them, the entire surface must be plastered, otherwise there will be certain technical difficulties when connecting with the wall. , the connection is not firm, and there is a phenomenon of through cracks at the connection; the accessories such as the reverse valve, the reverse plate and the exhaust hole must be installed in advance, and it is difficult to realize mechanization; after the pipe is made, it can only be used for smoke exhaust replacement Gas, it is difficult to change to a house. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a type groove for exhausting smoke and venti...
