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 for a ventilation, air conditioning, and smoke prevention system and a method for using the same. Background technique

[0002] The raw materials for the production of pipe fittings for ventilation, air conditioning and smoke control 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 by using wooden molds. When making pipe fittings, first determine the specifications and quantities of the pipe fittings to be made according to the construction drawings, and then determine the number of sets of wooden board molds according to the requirements of the construction period. After the mold is made, the inorganic gelling material is stirred in the mixing equipment and then manually p...

Embodiment Construction

[0027] As shown in the figure, a special tool for making pipe fittings for ventilation, air conditioning and smoke prevention systems and its usage method. The pipe flange 7 and the tube sheet 6 can be assembled together accurately at one time by using the provided special tools. During the assembly process, the overall bonding condition can be achieved without repeatedly adjusting the verticality of the tube sheet 6 and the flange 7 .

[0028] When the special tool is combined with the pipeline, the position of the connecting plate 4 is on the inner side of the flange, and the flange 7 is tightly fixed on the connecting plate 4 through the pressing device 3 and the backing plate 2, so that the flange 7 and the connecting plate 4 become a whole. At this time, the connecting plate corrects and strengthens the flange. The tube plate 6 is installed on the top of the connecting plate 4, and the groove end is close to the flange 7, and it is integrated with the connecting plate 4...
