Description

CURVED BUILDING ELEMENT AND METHOD FOR ADJUSTING CURVED BUILDING ELE MENT
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.
In what follows, for the sake of detail, 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.
A person skilled in the art will know that there are limitations on the length and width of load-bearing building elements, for example of floors and ceilings, that can be used without supporting devices being required. This puts restrictions on the construction and design of a building, including the utilization of area because of all the support required. This may be cost-pushing for the total cost, including life-cycle cost, func tionality and a more flexible field of application of the building. The second-hand value may thereby be lower.
Purely aesthetically and functionally, open flexible solutions without any support occu pying floor area are often preferred, for example for shops, business buildings, sports halls, storage buildings and other hall solutions.
Materials made of wood have been used for building materials for houses and other buildings from time immemorial. The kinds of timber used the most have been pine or spruce in our part of the world, while other kinds are also found. What types of timber are used depends on availability, demand and supply. In addition, there are require ments such as quality, strength, moisture content, stability and lifetime. And in recent times, the demand for locally produced materials has come as a weighty argument.
P29844PC00 description and claims, 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.
A person skilled in the art will know about several of the drawbacks of concrete as a load-bearing construction material; floors in concrete require bearing in the form of supports because of large own weight and therefore length limitations with such ele ments. This entails, among other things, longer building time and a reduction in the floor area by the pillars.
There are several types of building elements on the market today, in both concrete, steel, wood and other materials. There are several drawbacks to them, but they have in common that they have clear limitations in the longitudinal direction, and, in gen eral, long laminated wooden girders are cost-pushing. This results in supports having to be used, even for building elements in the form of floors/ceilings. However, great flexibility in the utilization of floor area is often given preference by using longer stretches of unsupported ceilings and/or floors.
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.
The object is achieved through the features that are specified in the description below and in the claims that follow.
For the curved building element according to the present invention to be usable on longer stretches without support, 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.
P29844PC00 description and claims, English translation Further, at least one curved reinforcing device is fixed to a curved tightening, sensor and fixing device. However, 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 (curved and non-curved), after the curved building element has arrived at the building site, ready for installa tion, and been put into place, 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. In one embodiment, 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
P29844PC00 description and claims, English translation the tensioning of the reinforcing devices combined with more fine adjustments of the tensioning of the reinforcing devices may hold the curved building element in a desired position which also locks the curved building element against deformations.
In addition, 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. However, should longer spans than those allowed by the curved building element without support be desired, 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 inventor has surprisingly found that 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.
In a first aspect, the invention relates to a curved building element. More precisely a curved building element for a floor, a ceiling, a wall and curved structures comprising at least one curved reinforcing device which is placed on the external side of the curved deck and in the longitudinal direction of the deck and is attached to a curved tightening, sensor and fixing device. The curved reinforcing device is attached to transverse elements at each longitudinal end of the curved building element. At least one (non-curved) reinforcing device may be crossed or oriented parallel to the longi tudinal direction of the curved building element. The reinforcing device is fixed to the tightening, sensor and fixing device that is attached to the transverse element and placed at each longitudinal end of the curved building element. Longitudinal side ele ments may include longitudinal braces which are placed on the same side of the side

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.
According to a second aspect, the invention relates to a method for adjusting the curved building element according to the first aspect of the invention, the method be ing characterized by comprising tightening, adjusting and reading values from the sensors that are connected to the tightening, sensor and fixing devices and the curved tightening, sensor and fixing device fixed to, respectively, the (non-curved) reinforcing device and the curved reinforcing device, and possibly readjusting distortions caused by undesired forces, both during the installation and the time after, on the curved re inforcing device and the reinforcing device of the curved building element by means of the tightening devices that are placed on the tightening, sensor and fixing devices and curved tightening, sensor and fixing devices. First, the reinforcing device is tightened, then the curved reinforcing device is tightened and adjusted alternately with the rein forcing device.
In what follows, examples of preferred embodiments are described, which are visual ized in the accompanying drawings, in which:
