There is provided a floor structure for a booth that is installed on an installation surface and that includes a side wall and a door through which a user enters and exits the booth. The floor structure includes a floor surface of a space that is enclosed by the side wall and in which a desk and a chair are placed on the floor surface and a fastener that fastens the floor surface to the installation surface and that is provided so as to be accessible. The floor surface is divided, outside a range of motion of the chair, into portions including a removable portion.

An impact shield for earthquake protection is described herein. The impact shield may include a canopy constructed of a puncture-resistant material, the canopy defining a first internal volume accessible via a first opening, the canopy being structured to form a semispherical shape when in an inflated state, the semispherical shape defining a space dimensioned for sheltering at least one human body; a support joined to the canopy and constructed of the puncture-resistant material, the support defining a second internal volume accessible via the first opening and a second opening, the support located within the space, the support structured to form a column when in the inflated state; and a fitting joined to the support for closing the second opening to fix the first internal volume and the second internal volume after inflation of the support and the canopy.

The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

The present invention relates to an anti-seismic protection device (1) that can be installed in a home, comprising: a base frame portion (2A) comprising at least four base tubular elements (21A) made of carbon fibre arranged in plan so as to constitute the vertices of a base rectangle, said tubular elements being connected to each other by means of tubular base frame beams (23 A) made of carbon fibre, arranged to form diagonals of the base rectangle, a shower tray (3) coupled to said base frame portion (2A) provided with a water drainage hole, a cap frame portion (2B) comprising at least four cap tubular elements (21B) made of carbon fibre arranged in plan so as to constitute the vertices of a cap rectangle, said tubular elements being connected to each other by means of tubular cap frame beams (23B) made of carbon fibre, said second tubular cap frame elements (23B) being arranged to form diagonals of the cap rectangle, wherein each tubular cap element (21B) in operating condition is placed on the vertical of a corresponding base tubular element (21A), spaced therefrom an intermediate frame portion (2C) comprising four tubular uprights (21C) that can each be coupled at an opposite free end to one of the four base tubular elements (21A) and to the corresponding cap tubular element (21B) placed on the vertical, and wherein the intermediate frame portion (2C) further comprises at least three peripheral walls (22C), each peripheral wall (22C) extending between two neighbouring uprights (21C) a water dispenser coupled to the cap frame portion (2B) or to the intermediate frame portion (2C), such that the anti-seismic protection device (1) can be used as a shower cabin.

The purpose of the invention is to reduce a cost and a construction period, secure measures for stability of the shelter main body against a tsunami, water pressure resistant performance against the tsunami generated by the Nankai Trough Great Earthquake, safety performance necessary for using the evacuation shelter, and good living comfort, and shorten evacuation time. The shelter main body 3 is connected to the concrete foundation 2 and has a structure with the frame 3a of a columnar structure, the ceiling 3b, and the internal space 9 of a columnar structure. The inner hatch 5 is attached to the periphery of the opening 4 provided in the ceiling 3b by a hinge in an openable and closable manner. A rising portion 6 rises upward from the peripheral edge of the opening 4. The outer hatch 7 is connected to the upper surface of the rising portion 6 by a hinge 7a in an openable and closable manner. A pair of rails 8 is arranged in the vertical direction on the inner wall surface of the frame 3a of a columnar structure of the shelter main body 3. The movable floor 10 is capable of moving up and down inside the internal space 9 along the rails 8.

A convertible protective shelter for people to shelter and stay in during unsafe situations, such as earthquakes and windstorms. The shelter can protect occupants from falling materials or debris. This shelter is readily convertible into a table for general household use when it is not required, and can be readily deployed when it is required. A plurality of elongate support members which form the arched structure of the shelter may be converted into leg structures for the undeployed shelter (table). The shelter can also be provided with at least one protective door, which optionally can be foldable to facilitate storage of the protective door when the shelter is not in use.
