A sheltering system comprised of a housing unit made of at least one panel connected to a base with one or more entrances into the housing unit and a structural framework with at least one beam that extends the length or width of a panel or base on the housing unit. The beam has at least one notch near the joining of two panels or a panel and the base. The housing unit may be connected to an air intake system that allows for air to move into the interior of the housing unit and then egress out

The present application discloses an anti-seismic braced scissor stairs and a frame stairs system. The stairs includes a first platform, a second platform, a third platform, a fourth platform, a fifth platform and a sixth platform. A first stair slab and a first inclined beam are provided between the first platform and the fourth platform; a second stair slab and a second inclined beam are provided between the second platform and the third platform; a third stair slab and a third inclined beam are provided between the third platform and the sixth platform; a fourth stair slab and a fourth inclined beam are provided between the fourth platform and the fifth platform. The first inclined beam and the second inclined beam are crosswise arranged to form a first cross bracing, and the third inclined beam and the fourth inclined beam are crosswise arranged to form a second cross bracing.

Disclosed is a method for producing a structural element by joining together at least two separately produced parts where at least one part is made of concrete by cutting it from a volume of concrete and where all parts extend over the entire length of the structural element; a method for producing a staircase by joining together at least two separately produced staircase parts, which are cut from a volume of material and extend over the entire length of the staircase, and a structural element and a staircase which have been produced in this way.

The invention relates to a load-transferring connecting element (1) for establishing a connection between a first building element and a second building element. The load-transferring connecting element is adapted for transfer of forces between the two building elements. The load-transferring connecting element (1) comprises an elongated box-shaped main body (24), wherein a first end portion (3) of the load-transferring connecting element (1) is arranged for attachment into the first building element with a remaining second end portion (4) of the load-transferring connecting element (1) positioned so that it projects from the first building element. The second end portion (4) is adapted for being received in a cavity (13) arranged in the second building element, and is provided with an attachment area (5) for attaching lifting equipment (8) for handling the first building element.

A method of forming a lift shaft or similar in a multi-storey building is disclosed. The method includes the casting the shaft in segments (typically in the order of 800 mm deep) and then assembling the segments atop each other to form the shaft. The segments have vertical passages which align to form channels in which rebar can be inserted to tie the structure together.
