You are trapped in a room where the walls, ceiling, and floor are 10 ft thick and solid concrete. How do you escape? More details in the description.

The room may be in the shape of a cube, but you can not designate that the room should not be a dodecahedron at any time.

This greatly reduces the thickness of the concrete. Specify the concrete thickness to 10 feet. First, I will focus on the vertices. Even if my skin breaks, my hand shrinks to the naked bone, and I may make a hole through it. When my right bleeding becomes serious, I can use cotton dress to make my tourniquet on my right hand. Then I will pop out with my left hand

If your skin is out of fingers or elbows, you can not penetrate concrete. I take a hammer from the back pocket (I have not touched the details of the problem or the problem), I use a broken piece of broken bone as a nail and go through with a hammer. A finger bump strikes the weak point of the structure and an opening that penetrates a fragile apex is formed.

If that fails, I always operate my rock drill at the corner of the room and use my feet to make an escape cabin; my hands are hurt and can not be used.

After determining the size of the beam, temporary walls are created on both sides of the load bearing wall. Open the opening in the ceiling and wall on both sides of the beam and secure a space to hit the joist hanger. 4 feet wide opening (total) gives you work space and allows you to open the opening with dry wall. Temporary walls were initiated by screwing 2 x 4 to a ceiling approximately 3 feet from a load bearing wall. Next, place another 2 x 4 on the floor (there is no need to tighten) and nail the bolts directly under each ceiling beam. Make the stud fit snugly between 2 x 4 plates and secure the shim loosely. Once the temporary wall is completed, you can peel off the load bearing wall

Cut the "display" slot 1 foot wide on the dry wall of the ceiling next to the wall, make sure the floor beams are overlapping, pay attention to the span at the edge of the wall (Figure 3). If the end of the beam from one room overlaps two inches or more, a support wall close to the support wall is formed to support the end of the beam. If the beam is a single continuous plate, one wall will also work. However, if the beams are joined end to end, or if some of the edges do not extend sufficiently to be supported by a temporary wall, support walls are required on both sides of the load bearing wall. If a second wall is required, at least 2 feet away from the load bearing wall to secure the working space and slide the beam in place. The second wall can be mounted directly beneath the dry wall and there is no need to cut another slot.

The floor area does not include the number of rooms required by walls, dividing walls, stairs and bathrooms, and engineers. It is made of protective ceilings made of wood made from 250 mm thick brick walls and rigid walls and rigid walls, composed of suitable cement mortar in a 250 mm thick brick wall to satisfy the technician's satisfaction. Should be done. The floor should have a smooth surface and a smooth appearance and a concrete with a thickness of 75 mm with a 30 mm thick mortar at the top. The foundation of this building should be satisfactory to the engineers. The building requires the necessary number of doors and windows. If necessary, we will install a backup generator to provide an uninterruptible power supply.
