Abstract

The invention belongs to the field of air supply pipe positioning dies, and particularly relates to a nut tightening and shaping die special for a narrow-space positive pressure air supply pipe and aconstruction method. The die comprises a novel shaping plate; two sides of the novel shaping plate are respectively provided with novel clamping rods capable of moving; shaping holes are formed in themiddle of the novel shaping plate; and shaping bolts are arranged in the shaping holes. In addition to the above-described structure, a method for specific constructions using the die is also provided. According to the integral design, the nut screwing and shaping die special for the narrow-space positive pressure air supply pipe is adopted to carry out flange connection construction in the narrow space; operation action is simple and rapid; fastening problem of the flange connection bolt of the air supply pipe in the narrow space can be effectively solved; firmness and tightness of connection of the air supply pipe are guaranteed; the method has the characteristics of low construction cost, effective control of construction difficulty and improvement of appearance quality of finished products; and the method is very suitable for construction of fastening the flange connecting bolt of the air supply pipe in the narrow space.

Description

technical field [0001] The invention belongs to the field of positioning molds for air supply pipes, in particular to a special nut tightening and shaping mold for positive pressure air supply pipes in narrow spaces and a construction method. Background technique [0002] At present, air duct flange connection is a common air duct connection method in ventilation and air-conditioning engineering. It is widely used in air-conditioning ducts and fire-fighting smoke exhaust ducts. The conventional construction method is to use angle steel as flange mechanical punching bolts During installation, manually tighten the flange bolts to complete the combined connection of the air duct. The application number is CN201420119587.3, which discloses a metal composite foam air duct and its connection structure. The metal composite foam air duct is mainly composed of a common plate flange air duct, and two different types of common plate flange air ducts are embedded Sleeves, which respect...
