Abstract

An earthquake-resistant building connection includes first and second structural elements lying a distance from each other, where the first element includes an outer side face that faces the second element. The first element includes at least one projecting member that projects from the outer side face of the first element into a cavity in the second element. The cavity is wider, higher and deeper than the member. The first element also includes an elastic component for absorbing forces and motions of an earthquake. The component has an outer surface that extends around the member and faces the second element, forming a fill area between the outer surface of the component and the second element and further between the member and the cavity. The fill area is filled such that forces and motions transferred between the first and second elements in the event of an earthquake are absorbed in the component.

Claims

1. An earthquake-resistant building connection comprising a first structural element and a second structural element that lie at a distance from each other, and where the first structural element comprises an outer side face facing the second structural element, which first structural element comprises at least one projecting element that projects from said outer side face of the first structural element and into a cavity in the second structural element, which cavity is wider, higher and deeper than the projecting element, which first structural element further comprises an elastic element for absorbing forces and motions in the event of an earthquake, which elastic element has an outer surface that extends around the projecting element and faces the second structural element, whereby a fill area is formed between the outer surface of the elastic element and the second structural element, and further between the projecting element and the cavity, which fill area is filled with a filler such that forces and motions that are transferred between the first structural element and the second structural element in the event of an earthquake are absorbed in the elastic element.

2. An earthquake-resistant building connection according to claim 1,

wherein the placed material in the fill area is unreinforced concrete mix or mortar.

3. An earthquake-resistant building connection according to claim 1,

wherein the outer surface of the elastic element lies essentially flush with said outer side face of the first structural element.

4. An earthquake-resistant building connection according to claim 1,

wherein the elastic element is made of a rubber material.

5. An earthquake-resistant building connection according to claim 1,

wherein between the first structural element and the second structural element there is arranged a placement element such that the placed material in the fill area on the first structural element is only in contact with the elastic element.

6. An earthquake-resistant building connection according to claim 1,

wherein the at least one projecting element is a telescopic inner tube that is arranged in an outer tube, which outer tube is fixedly arranged in the first structural element.

7. An earthquake-resistant building connection according to claim 1,

wherein the first structural element is a landing and wherein the second structural element is a wall in a stairwell.

8. An earthquake-resistant staircase system comprising a stairwell and at least one staircase unit comprising at least one landing, wherein the at least one staircase unit and the at least one landing are arranged in the stairwell, and wherein the at least one landing is connected to the stairwell by a plurality of earthquake-resistant building connections according to claim 1.

9. An earthquake-resistant staircase system according to claim 8,

that wherein the at least one landing comprises at least four side faces, of which at least two of the side faces are opposing and face opposing walls in the stairwell, and wherein each of the two opposing side faces are connected to the opposing walls in the stairwell by at least one earthquake-resistant building connection.

10. An earthquake-resistant staircase system according to claim 8,

wherein the at least one landing comprises at least four side faces, of which three of the side faces face a wall in the stairwell, and wherein each of the three side faces are connected to the stairwell by at least one earthquake-resistant building connection.

11. An earthquake-resistant staircase system according to claim 8,

wherein the staircase unit comprises a lower landing and upper landing and a staircase section that extends between and is fixedly connected to the lower landing and the upper landing, and wherein the lower landing and the upper landing are both connected to the stairwell by at least one earthquake-resistant connection.

12. An earthquake-resistant staircase system according to claim 11,

wherein the lower landing and the upper landing each comprise a side face facing in the opposite direction to one another and which each face two opposing walls in the stairwell, which side faces are connected to the opposing walls in the stairwell by at least one earthquake-resistant connection.

13. An earthquake-resistant staircase system according to claim 8,

wherein between the stairwell or an adjacent landing and at least one side face of the at least one landing, which is not connected to a wall in the stairwell by the earthquake-resistant connection, there is arranged at least one elastic element.

14. An earthquake-resistant staircase system according to claim 8,

wherein there is arranged at least one elastic element between the stairwell and at least one side face on the at least one landing that is connected to the stairwell by the earthquake-resistant connection.

15. An earthquake-resistant staircase system according to claim 13,

wherein the elastic element is made of a rubber material.
