Seeking for a solution to your construction employee's official request?How about considering modular house?

For any construction enterprise,it is a common thing to deploy the installation workers to local construction site to fulfill their duties.However,the worker's safety and well-being must come first at any circumstances which is foundamentally provide them satified accommodation,catering and leasurement options at spare time.On the other hand,considering the high requirements of mobility and easy-to-assemble for the auxiliary house/building.modular house is definitely a reliable choice.

You may wonder what is exactly the define of a modular house system.To start with,Modular House is a term used to describe the use of factory-produced pre-engineered building units that are delivered to site in Modules. The modular units may form complete rooms, or parts of rooms.

Modular houses are generally made into six sided boxes constructed in a factory, then delivered to site and using a crane, the modules are set onto the building's foundation and joined together to make a single building. The modules can be placed side-by-side, end-to-end, or stacked, allowing a wide variety of configurations and styles in the building layout. 


Till now,you may get a little hint of what a modular house is.But the truth is there are still many things about modualr house to explore.So how about getting to read the following informations about KXD's unique modular house system?I'm sure that you will know deeper about the modular house system after reading the informations.

 

General

The modular unit or container is designed as a light solid construction consisting of floor and roof frames and corner profiles. The system enables compounding of individual containers in longitudinal and transverse directions without limits. It also enables compounding of containers in 2 floors in height (ground floor + first floor), or in 3 floors in height for warehousing of these containers (ground floor + 2 floor). Wainscots of the container are made of light insulation panels and offer pleasant climate in the interior due to their building and physical properties.

 2)When there is welding backing, we require the groove direction being outward for the flange plates(opposite direction for web plates) and still falls on the direction in favor of welding on web plates. Please refer to illustration 2
3)Butt-welding on construction site:we require all the grooves should be bevelled on the upper rafter/column when it comes to bolt connection for web plates(see illustration 3). For the scenario of welding on web plates, please refer to the illustration 4.
3.3.2 Box column(groove on itself).See illustration 5
