Problems solved by technology

For the air duct with concrete walls on all sides, the air duct can only be installed from the top of the air duct downward. When the building height is high, it is difficult to install by this method, and the strength of the air duct cannot be guaranteed. Air ducts often tear due to the influence of their own weight, which increases the air leakage of the

Example Embodiment

[0012] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0013] Such as figure 1 As shown, the civil air duct lined air duct structure provided by the embodiment of the present invention includes at least one section of air duct 1, a steel frame 2 and concrete; the steel frame 2 is arranged on the outside of the air pipe 1 and connected to the air pipe 1; concrete is poured Outside the air duct 1, the inner wall of the casted concrete structure 3 is in contact with the outer wall of the air duct 1, and the casted concrete structure 3 covers the steel frame 2.

[0014] In this embodiment, the air duct 1 is used as the inner formwork for pouring the concrete air duct. Before pouring, the air duct 1 and the steel frame 2 can be tied and welded to enhance the connection strength between...

Abstract

The invention relates to a civil engineering air duct lining air pipe structure and a construction method thereof. The structure comprises at least one section of air pipe, a steel reinforcement framework and concrete; the steel reinforcement framework is arranged on the outer side of the air pipe, and is connected with the air pipe, the concrete is poured to the outer side of the air pipe, the inner wall of the concrete structure formed through pouring is in abut joint with the outer wall of the air pipe, and the concrete structure formed through pouring wraps the steel reinforcement framework. According to the technical scheme, the mounting difficulty of the air pipe can be reduced, the system reliability can be improved, an air pipe mounting space does not need to be reserved, and the occupied area of a whole air duct can be reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a civil air duct lining air duct structure and a construction method thereof. Background technique [0002] With the official implementation of the "Technical Standards for Smoke Prevention and Smoke Exhaust Systems in Buildings" (GB51251-2017), it is required that the mechanical pressurized air supply system and smoke exhaust system of buildings should not use civil air ducts, and the vertically arranged pipes should be installed in independent In the pipe well, this requires lining the air duct in the civil air duct. The traditional lining air duct adopts a segmented construction method, that is, select a construction layer every two to three floors, and install the air duct in the civil air duct from top to bottom, which requires at least one side of the air duct to be bricked. wall, and installation is difficult. For the air duct with concrete walls o...
