Description

Installation Method of Toilet Module in Large Main Building with In-fill Method The present invention relates to a method for installing a toilet module within a structure, and more specifically, to a method for installing a toilet module within a large structure using an infill method that allows a toilet module manufactured in a factory to be lifted at the site and safely and easily moved to the design location of the corresponding floor for installation. Currently, construction sites are trending toward off-site construction methods due to the limitations of conventional methods. Amid this trend, the demand for a higher quality of life is rising, leading to an increase in individual workspaces within office environments, which in turn makes an increase in shared areas inevitable. Consequently, the expansion of modular structures is becoming unavoidable. For example, in the case of restrooms on standard office floors of large high-rise buildings, restroom modules are installed by utilizing the elevator hall space in non-operational sections within the core. Since the core of a high-rise building constitutes the Critical Path (CP) during construction and restrooms are one of the items where design decisions are made last, they are mostly installed using the In-fill method—which allows for installation regardless of the CP—among the primary installation methods (Stack or In-fill). The In-fill method is similar to creating and inserting drawers into a chest of drawers; it involves sliding the restroom module into the existing building frame. Consequently, there are constraints regarding floor height, floor finish height, and installation locations where the restroom can be In-filled during construction. As the size of the restroom module increases, technical methods are required to design and easily install the module while maintaining these constraints without modification. The technology forming the background of the present invention is Korean Registered Patent No. 10-2264712 (Patent Document 1), which proposes a "modular toilet and a method for constructing a building using the same." This involves manufacturing the modular toilet as a whole in a factory and supplying and installing it at the construction site to shorten the construction period and enable construction even during the winter season. However, the above background technology does not present a technical method for how the modular toilet transported to the construction site is installed at the installation location. Another background technology of the present invention is Korean Registered Patent No. 10-2281887 (Patent Document 2), which proposes a "method for constructing factory-made toilet modules using an opening in the ceiling slab of a building." This method allows for the lifting and installation of factory-made toilet modules through an opening in the ceiling slab to simplify on-site work for toilets. However, the above background technology has the problem of being complex overall and having a long construction period due to the installation of formwork, reinforcement, and concrete curing, as a slab opening must be constructed in the ceiling of the corresponding floor before the toilet module is installed, and the pouring work to close the slab opening again after the toilet module is installed. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description thereof; therefore, the present invention should not be interpreted as being limited only to the matters described in the attached drawings.
