Description

Technical Field

[0001] The invention relates to the technical field of flue construction, in particular to a flue reserved hole plugging anti-ridge one-step forming mold and a construction method thereof. Background Art

[0002] At present, when pouring floor slabs in construction projects, holes for flues are generally reserved. In order to better install the flue, the reserved holes are generally larger than the specifications of the finished flue. Therefore, after the flue is installed, the reserved holes must be sealed. At present, in the construction process of sealing the reserved holes of the flue and the flue counter-ridge, the conventional practice is to cast the sealing of the reserved holes of the flue and the flue counter-ridge in two times. First, the reserved holes are sealed and then the formwork is set up to cast the flue counter-ridge. Both castings use wooden formworks and simple supporting rods for formwork installation. This support method not only has low support strength, but also the wooden formwork is easy to shift, resulting in leakage when pouring the counter-ridge. At the same time, the separate casting of the hole sealing and the counter-ridge also increases the risk of leakage. In addition, this method takes a long time to construct, the turnover rate of the formwork device is low, and a large amount of manpower and material resources are wasted. At the same time, it may also increase the later construction cost.

[0003] Conventional practices have many disadvantages: (1) The reserved opening for the flue and the counter-bump are cast separately, and are not cast in one go, which greatly increases the risk of leakage at the opening. Repairing the leakage point later will waste a lot of time and reduce economic benefits; (2) When sealing the reserved opening for the flue and casting the counter-bump, the conventional formwork support method not only has insufficient support strength, but also the wooden formwork is easy to shift during the concrete pouring process, resulting in leakage during pouring; (3) The construction process of separate pouring is relatively cumbersome, and it takes a long time to process and install materials such as formwork and support rods, resulting in low construction efficiency and a lot of waste of manpower. (4) The wooden formwork can be turned over only 3-5 times, which means it cannot be turned over and used for a long time and has a low turnover rate. (5) The wooden formwork has low rigidity and is easily deformed by the pressure of concrete, which affects the quality of the flue counter-edge product. Large deformations need to be re-drilled and repaired, which not only increases the construction cost but also affects the construction progress. (6) The chiseling process of the reserved flue opening may cause inconsistent dimensions, and the same set of formwork cannot be turned over and used, which has low applicability. (7) The wooden formwork has a low turnover rate and will generate a large amount of construction waste, which does not meet the green construction concept and environmental protection requirements.
