A ramp assembly includes a decking system and a handrail system, an interface between the decking system and the handrail system, and a support system pivotably coupled to the interface. Other embodiments include a swivel bracket and a method of assembling a ramp assembly.

Disclosed is a vehicle maintenance dock including: a work space provided to elongate in a first direction, and formed to be dug in a predetermined depth with respect to a ground surface, and is provided to have an opened upper surface; and a plurality of vehicle support modules provided to shield one side of the opened upper surface of the work space and guiding a maintenance target vehicle to enter in a second direction inclined to the first direction and provided so that a maintenance target area of the maintenance target vehicle is exposed to the work space and continuously arranged in the first direction and arranged to be parallel to each other.

A recreational vehicle (RV) includes a ramp door configurable as a ramp or as a patio deck. A stair is attachable to a side of the door. A railing extends about the perimeter of the door when in the deck configuration. First and second support cables may be connected between the door and the RV to support the door when in the deck configuration.

A stair system with freedom of movement between landings associated therewith includes a connection system configured to connect stairs to a landing associated with a construction, wherein the connection system structurally supports the stairs for safe egress over the stairs while concurrently supporting movement between the landing and a second landing associated with the construction by the stairs in at least one dimension, and wherein the movement supports inter-story drift between the landing and the second landing and removes some force translation between the landing and the second landing.

In a method for modernizing a building, a former stairwell of the building is converted such that an elevator shaft of an elevator system to be constructed can be provided in the former stairwell. The elevator shaft is provided in the former stairwell of the building such that stepless access is facilitated to specific floors of the building from an elevator car of the elevator system, which car can be provided in the elevator shaft. A new staircase is constructed outside the former stairwell. In addition, a former staircase is removed from the former stairwell. Furthermore, access bridges are disposed next to the elevator shaft in the former stairwell, thereby enabling flush access from the new staircase to the specific floors.

An aerated concrete-hybrid construction element comprises a plurality of support structure profiles integrated therein and arranged parallel to one another at a distance from one another. The support structure profiles have a rib running transversely to the plane of the construction element, each with a respective support structure limb angled in the same direction away from the plane of the rib and running parallel or approximately parallel to the adjacent outer surface of the construction element. The support structure limbs of the support structure profiles are cast into an aerated-concrete layer extending over the length of the support structure limbs in their juxtaposed arrangement.

The invention provides a composite and modular intermediate deck, designed to divide a micro home into an upper living volume and a lower living volume below the intermediate deck. The intermediate deck is characterized by having a U-shaped slot comprising from 10% to 60% of the total surface of the platform, which allows maximizing usage of vertical space by making the U-shaped slot, which serves as a corridor in the upper living volume, coincide with non-crossable spaces in the lower living volume. The height of crossable areas of the upper living volume is given by the distance from the floor to the flat surface of the intermediate deck. A micro home unit characterized by featuring the abovementioned deck is also provided.
