Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a standardized air duct hanging hole mold. Background Art

[0002] In order to meet the needs of exhausting smoke from kitchens and bathrooms in high-rise and super-high-rise residential buildings and to keep the air fresh, exhaust ducts need to be installed in residential buildings. The construction technology of exhaust ducts has therefore developed and matured rapidly. In the prior art, the construction process of exhaust ducts mainly includes: calibrating and cleaning the size and position of the reserved opening → leveling the first-floor mortar → placing the first-floor exhaust duct → checking the elevation and correcting the verticality of the exhaust duct → placing the exhaust duct steel bars → applying cement mortar at the interface → placing the upper exhaust duct → sealing the flue opening.

[0003] Among the above-mentioned processes, plugging is the last process but also a key process. It must be carried out strictly in accordance with the requirements during construction to ensure quality. However, in actual construction, there are many defects in plugging construction. At present, when plugging the reserved hole, traditional hanging formwork casting is mostly used. Usually, plywood with a width of 50mm wider than the bottom of the plate seam and a thickness of 15mm is used. A hole with a diameter of 5mm is drilled on the plywood for passing the wire. The wire is inserted and fixed firmly. After tightening, the formwork can be tightly fixed at the joint, and then fine stone concrete is poured. This hanging hole method is time-consuming and labor-intensive to install, difficult to operate, and has high comprehensive costs. In addition, there is a high possibility of mold expansion, uneven and loose joints, and the density does not meet the requirements. There are also large removal work and serious leakage risks in the later stage due to defects such as wire passing through the plate and pulling the die, which leads to extremely reduced plugging quality and labor and material waste. There is no easy-to-implement operation on site that can be promoted and used.

[0004] In view of this, the inventor has designed a standardized air duct hanging hole mold based on many years of production design experience in this field and related fields and through repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content
