Abstract

PROBLEM TO BE SOLVED: To provide a highly strong part in a tunnel shape at part of a building and escape through it at the time of building collapse due to an earthquake or the like. SOLUTION: This is a tunnel which is made up by combining plural frames 1 with plural beams 2 and affixing slabs to the top and the bottom, and is provided by penetrating a room wall, and doors are provided at the parts of the wall and the tunnel inside. At the time of emergency, the inside and outside of the room are made through by opening the doors, or at the time of an earthquake, a floor under a bedding is opened downward, and the lower part becomes a tunnel passing under the floor.

Description

[Detailed Description of the Invention] [Industrial field of application] Installed in a part of a building or installed later.

[Technology of Raira] It seems that there is no escape tunnel when the building collapses.

[Problems to be solved by the invention] When a building collapses due to an earthquake or the like, it is disastrous to be trapped in a room or to be crushed by death. It was made into a shape, and it was easy to escape from there.

[Means for Solving the Problem] A plurality of frames and a plurality of beams are combined as shown in [Fig. 1] [Fig. 2] and [Fig. 3], and the wall is penetrated by a structure in which a plate is vertically stretched. So that it can be installed. Install the door on the wall.

[Operation] When the door of the wall that penetrates is opened, the inside and outside of the room are connected by a tunnel, helping to escape. In addition, since it is possible to enter and exit from anywhere due to its structure, it is possible to enter and exit from a convenient place without a feeling of blockage. The structure of the frame and beams supports the fall of heavy objects, and the upper plate prevents the fine fall objects. The strength of the tunnel should be decided by assuming the fall objects at the time of collapse.

[Embodiment] The room is installed from the floor to the outside through the wall. There should be a door on the wall, so that if you are on the second floor or above, you can fold the external tunnel up, and if the stopper is removed manually from the seismograph or if you manually remove the stopper, it will be deployed horizontally outside. , Attach a ladder to the tip,
In this case, it is effective even when you cannot get down to the lower floor due to flood damage. Also, when installing under the floor, both the floor of the room and a part of the upper plate of the tunnel are set as an open door and the door is entered from there. When not in use, you can prevent insects and small animals from entering by attaching transparent plates from the outside to the side and end faces. It is also convenient to have an emergency light automatically turn on when the weight of the lower plate is heavy. In addition, if the floor under the futon of the room has a structure that opens downwards in a double door, and in an emergency, open it downwards and drop the bedding under the floor so that it can be directly connected to the tunnel. Is likely to be saved. In a room with many people, such as a kindergarten hall or a gymnasium in a school, install a structure that bundles tunnels on the wall and use it by entering from the side [Effect of the invention] It can be prevented, and also useful for subsequent rescue. In the structure in which the frames are alternately inclined and connected to the beam as shown in FIG. 3, the inclination of the frame plays a role of a streak, and the strength can be increased.
