Combined special tool of tube manufacture for ventilating air-conditioner smoke prevention and discharge system and its use method

Abstract

The invention discloses a kind of special tool to make air conditioning, and its producing way. Its feature consists that the special tool is a kind of combinational tool, which includes shelf, mat, pressing instrument, linking board and a film. When combination, we need to put some shelves on the flat roof, in the hole we talked about from inside to outside put flange, linking board, tube board and mat board, fixed with bolt, through this we can link the four tube boards by the linking board and flange, then link the other side of flange in the same way. At this time, put the film in the four corners formed by the tube boards. Then fill the gaps with the material of inorganic glue, and form the stronger structure. The invention achieves the industrial work of tubes, increases the efficiency, economizes the wood, and increases the dimension precision, so it meets the standard requires, especially fits to use in the architectural instrument company.

Description

Technical field [0001] The invention relates to a vertical duct of an air duct or an air duct, in particular to a combined special tool for making pipe fittings of a ventilation and air conditioning smoke prevention and exhaust system and a method of use thereof. Background technique [0002] The raw materials for the production of pipe fittings for ventilation and air conditioning and smoke prevention and exhaust systems have so far been divided into two categories: metal and non-metal. Non-metallic materials are representative of inorganic cementitious composite materials, which are artificially pasted using wood board molds. When making pipe fittings, first determine the specifications and quantity of pipe fittings to be manufactured according to the construction drawings, and then determine the number of sets of wood molds according to the requirements of the construction period. After the mold is made, the inorganic cementitious material is stirred in the mixing equipment an...

AI Technical Summary

Problems solved by technology

At the end of the project, these molds will also be scrapped, and the consumption of wood is very large

[0004] (2) For pipe fittings made of artificial paste, the wall thickness of the pipe fittings, the uniformity of the surface technology and the laying of the glass fiber grid cloth are still difficult to meet the requirements of the national standard, especially the size and shape of the four corners of the rectangular section of the pipe are more prominent, which is Because part of the pasty inorganic cementitious material is taken away during the process of laying the glass fiber grid, the thickness of the remaining inorganic cementitious material is difficult to meet the requirements.

[0005] (3) Due to the slow speed of manual paste operation, long construction period, sufficient site and good climate, natural climate and other factors have a great impact on the progress of the project
