Abstract

The invention relates to the technical field of exhaust passageway construction, in particular to a mounting and bearing method of a residence kitchen and bath room exhaust passageway. A reserved holeformed in a cast-in-place floor, a lower exhaust passageway body, an upper exhaust passageway body and a tube mold are included. According to the mounting and bearing method of the residence kitchenand bath room exhaust passageway, constructional reinforcements are pressed into the periphery, a square barrel structure is actually formed by a second layer of concrete, as the reserved hole is an inverted quadruple-rim table, the tube mold is actually a hollow concrete wedge structurally, loads of the upper exhaust passageway body are borne by the hollow concrete wedge, and the loads are transmitted to the cast-in-place floor. By means of the constructional reinforcements, the integrity of the wedge can be enhanced, meanwhile, the corners are protected, breakage caused by detachment of thetube mold is avoided, meanwhile, the construction procedures are simple, the construction time is short, the bearing area of the upper exhaust passageway body is large, the phenomena of deforming andcracking are reduced, and the overall service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of exhaust duct construction, in particular to a method for installing and supporting exhaust ducts in residential kitchens and bathrooms. Background technique [0002] At present, the material of kitchen and bathroom exhaust ducts in residential buildings is generally cement products, and its wall thickness is generally within 20mm. There is no national unified standard for the installation method, and it is generally carried out according to the local recommended design atlas. The core and key is the support of the floor to the exhaust duct. If the support is proper and reliable, the exhaust duct will not sink, deform and crack after installation. On the contrary, it will cause a series of quality problems and affect the use and appearance. [0003] At present, the conventional method is to bury embedded parts at the four corners of the reserved opening of the floor, weld the supporting angle steel to sup...
