Connection arrangement from hollow steel sections which are subject to axial pressure
The invention relates to a connection arrangement of hollow steel sections as support elements which are interconnected using a joint connection, the connection being subject to axial pressure. According to the invention, the joint connection is designed as a detachable, form-fitting plug-in connection.
1. A framework construction, comprising:
support elements constructed as hollow steel sections, said hollow steel sections forming an upper chord, a lower chord and diagonal beams of the framework construction, wherein at least the diagonal beams are comprised of subsections,
a sleeve interconnecting the subsections,
wherein a first end of the sleeve is form fittingly received in an end of one of the subsections, and an end of another one of the subsections is form fittingly received in a second end of the sleeve resulting in a form fitting plug-in joint connection,
wherein said joint connection is subjected to an axial pressure load that permits axial movement of the one of the subsections relative to the another one of the subsections, and
wherein said joint connection does not comprise fastening elements that prevent said axial movement.
2. A framework construction, comprising:
support elements constructed as hollow steel sections, said hollow steel sections forming an upper chord, a lower chord and diagonal beams of the framework construction, wherein at least the diagonal beams are comprised of subsections,
wherein one of the subsections has a first inner diameter and a terminal section with a narrower second inner diameter, said terminal section being defined by a length, said second inner diameter extending along an entirety of said length, said first inner diameter continuously transitioning into said second inner diameter,
wherein another one of the subsections has an end with a constant inner diameter, said end detachably receiving the terminal section of the one of the subsections along the entirety of the length of the terminal section resulting in a form fitting plug-in joint connection,
wherein said joint connection is subjected to an axial pressure load that permits axial movement of the one of the subsections relative to the another one of the subsections, and
wherein said joint connection does not comprise fastening elements that prevent said axial movement.
3. A framework construction, comprising:
support elements constructed as hollow steel sections, said hollow steel sections forming an upper chord, a lower chord and diagonal beams of the framework construction, wherein at least the diagonal beams are comprised of subsections,
wherein one of the subsections has a first inner diameter and a terminal section with a wider second inner diameter, said terminal section being defined by a length, said second inner diameter extending along an entirety of said length, said first inner diameter continuously transitioning into said second inner diameter,
wherein another one of the subsections has an end with a constant outer diameter, said end being detachably received in the terminal section of the one of the subsections along the entirety of the length of the terminal section resulting in a form fitting plug-in joint connection,
wherein said joint connection is subjected to an axial pressure load that permits axial movement of the one of the subsections relative to the another one of the subsections, and
wherein said joint connection does not comprise fastening elements that prevent said axial movement.
4. The framework construction of claim 3 , wherein the hollow sections which form the upper chord, the lower chord and the diagonal beams of the framework construction are produced from welded, cold or hot finished seamless pipes.
5. The framework construction of claim 3 , wherein the hollow sections which form the upper chord, the lower chord and the diagonal beams of the framework construction are produced from hot finished seamless pipes.
6. The framework construction of claim 3 , further comprising a safeguard against unintentional release of the subsections.
7. The framework construction of claim 6 , wherein the safeguard is an adhesive.
8. The framework construction of claim 6 , wherein the safeguard is a clamping element.
9. The framework construction of claim 8 wherein the clamping element is a wedge.
10. The framework construction of claim 8 , wherein the clamping element is a clamping ring.
