example 1

[0020] Such as figure 1 As shown, the intake and exhaust holes on the smoke exhaust and ventilation duct are to add an annular hole edge 3 around the existing intake and exhaust holes 2 on the outer wall of the smoke exhaust and ventilation duct. The stomata 2 are the same and melt into one. The height of the hole along 3 is equal to the thickness of the plastered finish, or slightly higher than the thickness of the plastered finish.

example 2

[0022] The following production molds are required to make the above air intake and exhaust holes:

[0023] The mold is made as follows: an inner passage hole 6 and an outer passage hole 7 concentrically arranged on the pipe inner wall formwork 4 and the pipe outer wall formwork 5 of the smoke exhaust and ventilation pipe respectively, and the radius of the outer passage hole 7 is one larger than that of the inner passage hole 6 Hole along 3 wall thickness.

[0024] The fabrication of the hole rim 3 needs to use the channel inner wall template 8 and the channel outer wall template 9 at the same time.

[0025] Passage inner wall template 8 is cylindrical, and its diameter is identical with the inner passage hole 6 on the pipeline inner wall template 4, and its length is greater than the distance between the pipeline inner wall template 4 outer walls and the pipeline outer wall template 5 outer walls along the height of a hole.

[0026] Passage outer wall formwork 9 is a sectio...

example 3

[0029] The manufacture method of the intake and exhaust holes on the smoke exhaust and ventilation pipeline is: insert the channel inner wall template 8 through the outer channel hole 7 on the pipeline outer wall template 5 into the inner channel hole 6 on the pipeline inner wall template 4, and insert the channel outer wall template 9 Fix the outer periphery of the inner channel hole 6 on the outer wall template 5 of the pipeline, and then fill the slurry between the inner and outer templates respectively. After the slurry solidifies, remove all the templates, and the operation can be completed after trimming.

Abstract

The invention discloses an air inlet-and-outlet hole in a smoke discharge ventilation pipeline of a building and a manufacturing method of the air inlet-and-outlet hole in the smoke discharge ventilation pipeline of the building. The air inlet-and-outlet hole in the smoke discharge ventilation pipeline of the building is characterized in that a ring-shaped hole edge is added on the periphery of the air inlet-and-outlet hole in the outer wall of the smoke discharge ventilation pipeline, the inner diameter of the hole edge is the same as the inner diameter of the air inlet-and-outlet hole, and the hole edge and the air inlet-and-outlet hole are combined into a whole, the height of a hollow cylinder of the hole edge is equal to the thickness of a plastered veneer or is slightly larger than the thickness of the plastered veneer. The air inlet-and-outlet hole in the smoke discharge ventilation pipeline of the building and the manufacturing method of the air inlet-and-outlet hole in the smoke discharge ventilation pipeline of the building have the advantages that after plastering overcoating is carried out on a ventilation duct, the air inlet-and-outlet hole is still neat and artistic, and the operation of plastering is convenient.

Description

technical field [0001] The invention relates to an intake and exhaust hole on a smoke exhaust and ventilation pipe of a building, and also relates to a manufacturing method of the intake and exhaust hole. Background technique [0002] The prefabricated smoke exhaust and ventilation duct has the advantages of regular shape, convenient installation and maintenance, so it has been widely used by construction departments in recent years. The intake and exhaust holes on the smoke exhaust and ventilation duct are the portals to realize the smoke exhaust and ventilation functions, and the intake and exhaust holes are exposed outside the wall, so people attach great importance to the beauty and regularity of its appearance. Most of the currently used smoke exhaust and ventilation ducts will be plastered on the outer wall to make a decorative surface after installation. , It is very difficult to make a regular and smooth hole along the operation when plastering. Sometimes careless ...
