Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building construction, and in particular to a method for conveniently sealing a partition in a prefabricated flue. Background Art
[0002] With the development of construction technology, flue construction often uses prefabricated flues for construction in the air shaft. In order to avoid exhaust smoke backflow and cross-flow, a partition is added in the middle of the prefabricated flue to form a main and auxiliary flue. After the exhaust smoke enters the auxiliary flue, it enters the main flue through a vent that is higher than the exhaust port due to a certain buoyancy, which fundamentally avoids the situation where the smoke flows back through the exhaust port and flows back into the room, causing odor in the room. During the construction process, cement mortar is used to block the flues, but due to the small construction space between the partitions, cement mortar cannot be applied. The construction site often uses on-site materials for simple blocking or even no blocking, resulting in poor sealing between the main and auxiliary flues, which cannot isolate the smoke. Summary of the invention
[0003] In view of the above problems, an embodiment of the present invention provides a method for conveniently sealing a partition in the middle of a prefabricated flue.
[0004] An embodiment of the present invention provides a method for conveniently sealing a prefabricated flue intermediate partition, comprising: Making a partition sealing connector, the partition sealing connector includes an upper fixing part and a lower fixing part in a groove shape, wherein the groove of the upper fixing part faces upward and the groove of the lower fixing part faces downward; After the construction of the air shaft except the flue is completed, the garbage at the bottom of the air shaft is cleaned up, the prefabricated flue is placed in the installation position according to the requirements and the cement mortar caulking material is prepared; The prefabricated flue is installed in order from bottom to top. The first section of the prefabricated flue is installed first. The measuring and positioning device is used to adjust the first section of the prefabricated flue to the designed position. After applying cement mortar on the inner side of the lower fixing part of the partition sealing connector, the partition sealing connector is installed in a way that the lower fixing part is clamped on the partition. During the installation process, the position of the partition sealing connector is adjusted to ensure that it meets the vertical standard. Apply cement mortar on the inner side of the upper fixing part of the partition sealing connector, lift the second section of the prefabricated flue and insert the partition of the second section of the prefabricated flue into the upper fixing part, and adjust the position and verticality of the second section of the flue before the cement mortar begins to set; Refer to the construction methods of the prefabricated flues in Sections 1 and 2 to install subsequent prefabricated flues until all prefabricated flues are installed, and perform perimeter sealing of the flue to complete the flue installation project.
