Building having security and safety function

摘要

In known prefabricated buildings, a general ladder is used for the means for people to go up to the rooftop. In the case where the ladder is installed indoors, there is a problem that the space usability is relatively reduced. In the case where the ladder is installed outdoors, it can allow trespassing and poses a risk of safety accidents because children can easily go up the ladder. A building having a security and safety function of the present invention includes: a house body that is configured to include an inner panel that defines an interior space, an outer panel that surrounds the inner panel to be spaced a predetermined distance from the outer surface of the inner panel, a heat insulating material that is installed between the inner panel and the outer panel, and an air flow passage that is formed between the inner panel and the outer panel to facilitate a fluid flow therebetween and to block the heat transfer with respect to the outside; an indoor entrance door configured to be installed on one side of the house body for entering the interior space; and an outdoor entrance door configured to be installed on the house body in front of the indoor entrance door. A ladder is installed on the side wall between the indoor entrance door and the outdoor entrance door, which includes foot step members that are installed to be spaced a predetermined distance from each other to go up to the rooftop, and a plurality of guide holes are formed on the outdoor entrance door such that the foot step members are exposed to the outside of the outdoor entrance door when the outdoor entrance door is opened inwards and comes into contact with the side wall. The building can control the entry of children or outsiders into the rooftop of the building without permission from the user in order to thereby prevent safety accidents and in order to thereby improve a security function.
