Definitions

  • the present invention relates to a curved building element for a floor, a ceiling, a wall and curved structures. More precisely, the curved building element may be made from solid wooden planks, a laminated arch, laminated solid-wood elements, plates and/or wooden boards, wood- fibre boards crossed or steel, aluminium and composite materials, but is not restricted to the materials mentioned above.
  • the description will be directed towards a curved building element for a ceiling. This is because, irrespective of the field of appli cation, the embodiments of the building elements resemble each other. However, it will be understood that the building element according to the present invention may also comprise curved building elements for walls, floors and other curved structures.
  • English translation Wood is usually used in low buildings, and is used for, among other things, external walls, ceilings, cladding, internal walls, floors, and ceilings. When it comes to larger buildings, including business buildings, concrete and concrete elements and also steel are mostly used as construction and building materials.
  • US 5218801 A shows a curved building element for a ceiling structure including an upper tie bar, which is attached to mounting devices at the ends of the element.
  • the curved building element also includes a lower tie bar, which is attached to the ends of the element.
  • the invention has for its object to remedy or reduce at least one of the drawbacks of the prior art or at least provide a useful alternative to the prior art.
  • a principle is applied in which at least one reinforcing device, which may be in the form of, but not restricted to, a rope or wire in steel or composite materials or other materials, which is placed between each longitudinal end of the curved building element and fixed to tightening, sensor and fixing devices that are fixed to transverse elements at each longitudinal end of the curved building ele ment.
  • the reinforcing devices may either be placed parallel to each other in the longi tudinal direction of the curved building element or be crossed in the longitudinal direc tion of the curved building element.
  • At least one curved reinforcing device is fixed to a curved tightening, sensor and fixing device.
  • the curved reinforcing device follows the external surface of the curved deck.
  • the curved tightening, sensor and fixing device is fixed to a trans verse element at each longitudinal end of the curved building element.
  • the curved reinforcing device and the (non-curved) reinforcing device absorb tensile forces arising in the curved building element according to the present invention.
  • the curved reinforcing device may be attached to the curved deck in/near the middle of the curved building element in the longitudinal direction by means of friction devic es. This makes it possible for tightening, adjustments and readings from sensors to be done from both longitudinal ends of the curved building element, which facilitates in stallation and also better documentation on the installation and during operation.
  • the curved reinforcing device may be of another shape and design than the (non- curved) reinforcing device, for example of a rectangular or square design, but is not restricted to the embodiments mentioned.
  • the curved reinforcing device may have a low-friction material placed between the curved deck and the curved reinforcing device to facilitate the tightening of the curved reinforcing device.
  • a preferred method when tightening the reinforcing devices is to tighten the reinforcing devices by means of a tight ening, sensor and fixing device to sufficient values for tensioning, then the curved re inforcing device is tightened by means of a curved tightening, sensor and reinforcing device to a sufficient tension value.
  • Any fine-tuning of, alternately, the curved tighten ing, sensor and fixing device and the tightening, sensor and fixing device may be car ried out until sufficient tension on the reinforcing devices has been achieved.
  • the sen sors of the tightening devices give signals on the tension of the reinforcing devices, thereby making secure and quick adjustment of both types of reinforcing devices pos sible.
  • the sensors may be connected all the time, even after the installation and tightening, in order thereby to emit signals if something unforeseen should arise in the structure of the curved building element, and thereby avert dam age or other undesired events.
  • the reinforcing devices may also cross each other along the longitudinal direction of the curved building element.
  • Another advantage is that the reinforcing devices can be used to adjust distortions, form and level of the building element.
  • the weight of the curved building element will press the curved deck downwards, but
  • the curved building element may include side elements comprising longi tudinal braces that are placed on the same side of the side elements and are directed towards each other.
  • the side elements may be fixed to the curved deck and trans verse elements at each longitudinal end of the curved building element.
  • the main function of the side elements with longitudinal braces is to give strength to the curved building element, so that the geometry of the curved building element is maintained.
  • the tensioning of the reinforcing elements, the curved structure and, in some embod iments, the side elements with longitudinal braces constitute the main components that make longer spans possible without any supporting of the curved building ele ment for a floor, a ceiling, a wall and curved structures.
  • support may be used. But, looking at today's solutions with support of building elements, con siderably fewer supports will be needed for the curved building element according to the present invention.
  • the tensioning of the reinforcing elements (curved and non-curved), the curved structure and, in some embodiments, the side elements with longitudinal braces constitute the main components that make long spans possible without any supporting of the curved building element for a floor, a ceiling, a wall and curved structures.
  • the invention in a first aspect, relates to a curved building element.

  • the side elements may be placed on both sides of the deck and project on the top side and/or the bot tom side of the deck.
  • the curved building element may include sliding devices which are placed between the curved reinforcing device and the curved deck in the longitudinal direction of the curved building element. This enables a more secure and simpler tightening of the curved reinforcing devices because of lower friction.
  • Guiding devices may be placed on the sides of each curved building elements in the longitudinal direction, for example on the edge ends of the deck or on the side ele ments.
  • the guiding devices correspond with each other when several curved building elements are put together, so that they function as guides during installation, for ex ample, and thereby correspond with and guide each other so that the curved building elements can be installed edge to edge. This makes the installation of the curved building element easier and is time-saving.
  • the sensors that are used for the fixing-/tightening devices can be used for continu ously reading values from the reinforcing devices. Thereby it is possible to get read ings that can warn of changes and danger in the building structure. It is also possible to get readings for the curved building element and the rest of the structure for docu mentation.
