Mounting method of precast air duct during construction stage of construction engineering structure

Abstract

The invention provides a mounting method of a precast air duct during the construction stage of a construction engineering structure. According to the method, original procedures are changed, the air duct mounting operation is performed after main structure wall construction, and the air duct mounting operation and the top plate template mounting are performed together, each procedure in the existing construction method is omitted, synchronous air duct mounting and main structure construction progress can be achieved on the premise of not increasing construction materials and working hours, and the waterproof construction progress and quality of a roof are better ensured.

Description

technical field [0001] The invention relates to a structural construction and an installation method of internal components in a residential building, in particular to a construction method suitable for the installation of various prefabricated flue ducts. Background technique [0002] At present, the installation of prefabricated air ducts in domestic construction projects is usually carried out after the construction acceptance of the main structure. There are certain deficiencies in this construction method: (1) Since it is installed after the structural construction is completed, the front and rear processes are not closely connected, which affects the construction progress of the roof. Waterproof construction is a key construction process in roofing engineering. The construction progress of the smoke duct affects the waterproof construction. The current construction method is affected by the construction of the smoke duct in terms of progress; It is difficult to deal w...

This construction method has certain deficiencies: (1) Since it is installed after the structural construction is completed, the front and rear processes are not closely connected, which affects the construction progress of the roof

Waterproof construction is a key construction process in roofing engineering. The construction progress of the smoke duct affects the waterproof construction. The current construction method is affected by the construction of the smoke duct in terms of progress; It is difficult to deal with the part where the wall is attached to the wall, which will affect the quality of indoor waterproofing

During the installation process of the smoke duct after the structure is completed, because the wall has been completed, the part where the smoke duct is close to the wall is not easy to be completely sealed and compacted, leaving hidden dangers of water seepage; (3) When the smoke duct is installed later, Need to do a series of work such as "reserved opening treatment, vertical air duct, temporary fixation, formwork support, pouring micro-expansion concrete and formwork removal", which requires more labor and time; (4) The materials to be used are more used
