Problems solved by technology

[0003] At present, there are several ways to install metal air ducts in the civil air ducts: 1. The four-sided enclosure (masonry) of the civil engineering wells is fully hollowed out. The metal air ducts can be connected by flanges and then the surrounding masonry is built. This method is practical. It is relatively rare in engineering, the cost is high, and the construction period is also long
2. Full concrete structure shaft: This method can only be hoisted from top to bottom after the metal air duct flange connection, which is relatively rare in actual construction
[0005] The above-mentioned existing technical solutions have the following defects: when installing the air duct 10, it is necessary to connect the bolts and nuts one by one, so that the installation efficiency of the air duct 10 is low

Embodiment 1

[0039]Example 1: Referencefigure 2 For a socket wind tube connection fixture disclosed in the present invention, a connecting member, a connecting member including a connecting tube 1 and a limiting strip 2, and the limit strip is set to four, four limit strips 2 respectively set On the four outer sidewalls of the connecting tube 1, the limit strip is disposed as a square tube, and the limit strip 2 is soldered between the connecting tube 1.

[0040]Referfigure 2 withimage 3 The two ends of the connecting tube 1 are in adjacent dumping 10, respectively, and the connecting tube 1 is an interference fit between the air tube 10 to connect the adjacent air tube 10, and adjacent the air tube 10 is in the limit strip 2. On both sides.

[0041]Referfigure 2 withimage 3 The outer side wall of the connecting pipe 1 is also connected to the friction strip 3, the friction strip 3 is the rubber strip, and the outer side wall of the connecting pipe 1 is welded to the raised column 5, the friction stri...

Embodiment 2

[0044]Example 2: An air tube mounting method using the above-described inserted duct connection fixture is disclosed in the present invention, which includes the following steps:

[0045]S1: Fixed the reinforcing bar on the connection block 11, embedding the reinforcement in opposing two-watery wall 9, and inserts the limit block 7 on both ends of the square steel 6 and the limit block 7 on both ends of the square steel 6, Pouring concrete towards the T-shaped groove 8;

[0046]S2: Inserting a duct 10 into one end of the connecting tube 1, the rubber strip offs away from the inner side wall of the contact pipe 10, the rubber strip is compressed;

[0047]S3: Insert another air tube 10 on the other end of the connecting tube 1, the rubber strip deps from the inside of the contact pipe 1 to the inner side wall, the rubber strip is compressed.

[0048]The implementation principle of the present embodiment is that the steel bar is welded to the connecting block 11 before mounting the air tube 10, an...

Abstract

The invention relates to the technical field of building ventilation, and aims to provide a socket-type air pipe connection fixture, including a connecting piece, the connecting piece includes a connecting pipe and a limiting strip, and the limiting strip is arranged on the outer wall of the connecting pipe , the two ends of the connecting pipe are respectively located in the adjacent air pipe, the connecting pipe and the air pipe are in interference fit, and the adjacent air pipe is located on both sides of the limit bar. When installing the air duct, the present invention can make the installation efficiency of the air duct higher, and does not need to leave a construction space for workers to install bolts and nuts between the side wall of the civil air shaft and each side wall of the air duct, and can make The air duct requires less installation space.

Description

Technical field[0001]The present invention relates to the technical field of building ventilation, in particular, to a generic wind tube connection fixing member and a duct mounting method.Background technique[0002]With the implementation of the construction of anti-smoking exhaust system (GB51251-2017), mandatory requirements for mechanical pressurized air supply pipes and exhaust pipes installed in the civil engineering in the wellway, and the pipeline should be used to use pipelines. Air supply (exhaust), and should not use the civil engineering airway, anti-(row) tobacco pipe should be made of non-combustible materials and the inner wall should be smooth. Metal air tubes are usually used as the liner.[0003]At present, there are several ways in which the metal air tube in the civil cream is: 1. The all-round mode of the earth-constructive wellway can be connected (masonry) full-hollow mode, and the metal duct flange can be used to build a surrounding masonry. This method is actua...
