Definitions

• the invention relates to a shelter with an arch or ring-shaped steel-concrete structure.
• a large number of shelter buildings with steel-concrete structures are known. All designs have in common that they contain a rigid construction. For example, reference can be made to the protective space known from DE-PS 35 21 884.
• a sheet steel container provided as internal formwork for a shelter. The steel sheet container is provided with concrete on the outside.
• Such an extremely stiff steel-concrete structure can withstand significant impacts in the event of a crisis.
• this construction method does not do justice to modern explosives.
• the direction of development of modern explosives is to release the blasting energy in an increasingly short time. This results in ever larger peak loads, while the duration of the load is reduced. This is where the invention comes in, because the invention is based on the idea of working off the blasting energy or the peak loads.
• a protective space with an annular or arched structure is provided for this purpose, which is referred to below as a vault.
• the vault is formed by steel inner segments and outer building material segments, the outer building material segments being arranged on the inner steel segments and each combined steel building material segment being supported on the other steel building material segment via resilience elements.
• the load is processed by pushing the resilience elements together.
• the flexibility can be set so that not only is it possible to push the sheet together in the circumferential direction, but also to give in by bending the sheet.
• a shelter according to the invention can be prefabricated at the factory.
• the prefabrication can be complete. This presupposes, however, that the dimensions of the shelter allow transportation.
• the shelter according to the invention can also be easily transported in individual parts on site and assembled there.
• the prefabrication is then optionally limited to the steel segments and resilience elements if, for. B. for reasons of sealing, a closed concrete outer shell is provided on the shelter. When the outer concrete shell is closed, a deformation cavity is provided in the concrete shell in the area of the resilience elements. The deformation cavity is so large that the remaining concrete does not significantly impair the deformation work in the event of a load on the protective space.
• concrete segments are also included. Then the concrete segments together with the steel segments form finished parts.
• the deformation cavity existing between the segments in the area of the resilience elements is covered with sealing elements, and the joints between the segments lying next to one another in the longitudinal direction of the protective space are the same. Joint seals made of elastic plastic are also suitable here.
• the building material provided for the building material segments according to the invention is preferably concrete. Other building materials are also considered.
• the steel building material construction according to the invention for a shelter can be varied in many ways.
• the construction can be adjusted to the special requirements of the individual case.

• Steel segments 4 are likewise arranged one behind the other in the longitudinal direction of the arch 1.
• the number of steel segments 4 can be varied in the circumferential direction and also in the longitudinal direction of the vault.
• a screw connection is provided in the overlap area.
• the nuts of the screw connections are arranged on the inside of the shelter.

• the resilience elements 5.1 are arranged in a solitary manner, the resilience elements 5.3 in the elm (side area of the vault), the resilience elements 5.2 in the ridge area.

• the concrete segments 1.2 are prefabricated with the segments 4 at the factory and are delivered as components together with the resilience elements to the construction site and assembled there.

• the concrete segments 1.2 can be cast together for several segments 4. This creates a building material bar that extends over several segments and possibly over all segments.
• the building material bar distributes loads, which are directed to a single segment 4, over several segments 4 of adjacent segment arches.
• each segment 4 can yield to the load with its concrete segment until, for. B. the explosion energy has been processed or until the distribution of
• the flexibility elements are advantageously suitable for suspension of loads.

• suitable moldings or suitable formwork ensure that there is a sufficient deformation cavity behind the resilience elements and that the thickness of the concrete shell in this area does not lead to a substantial impediment to the resilience behavior.
• the above-mentioned inflatable cushions can serve as suitable shaped bodies or formwork bodies. In the inflated state, the pillows are positioned behind the resilience elements and are released after the concrete has solidified. After the air has been released, the pillows can be pulled out of the cavity. With a suitable cushion material, this is already possible without additional coating. Otherwise, the cushions can be detached with the aid of silicone or rubber or other known coatings.
• moldings can also be used to form cavities, e.g. B. hollow body made of wood, steel or plastic.
