DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATION
The present invention relates to a device for supporting a construction on a supporting surface, the construction including at least one form stable construction element having a lower side and two lateral surfaces facing away from each other and being a predetermined distance f apart, with which element the device shall be brought into engagement. The device includes a bearing part with an inner section and two outer, bending resistant sections arranged one on each side of the inner section. A spacer is provided on the lower side of the bearing part in each outer section, and they are arranged to keep the bearing part at a distance from the supporting surface. The construction further includes upwardly directed, co-operating clamping members permanently arranged on the upper side of the bearing part forming a stable unit therewith, wherein the clamping members define a space between them that reaches down to the inner section, for the receipt of the construction element.
Special construction elements in the form of holders, placed on the ground, are used for positioning base elements for the foundation of a building. To obtain the correct level of the base element a foot plate of specific height must generally be cast for each holder. This method is both time-consuming and laborious and does not always ensure an exact level of the base elements. An alternative method is to use inserts to achieve the correct level, but there is a risk of the holder slipping off the insert since the insert is not usually secured to the holder.
The object of the present invention is to provide a device for supporting a construction, e.g. a holder and base element of the type described, which eliminates the problems mentioned above and can be applied quickly and simply to the construction, thereby retaining it and adjusting the construction at a desired level.
The device according to the invention includes an inner section that is bendable by the influence of the load of the construction element, and a clamping member extending within each outer section, which consists of at least one rigid clamping plate with a plane perpendicular to the space and to the construction element. The clamping plates are arranged to press, in free engagement, against the opposite lateral surfaces of the construction element with clamping forces generated by the construction in the loading on the bendable inner section.
The device according to the invention can be used to support and preferably also to adjust the level of a number of different types of constructions comprising construction elements in the form of e.g. molds used when casting concrete floors; joists, used when laying floors indoors to carry wooden tiles or boards; walls to be erected and aligned; levelling planks used, for instance, when levelling the surface for tiling; base elements or holders therefor, and other types of molds or beams that must be adjusted vertically; pipes for various purposes; spacer elements used when forming roofs; and screeds for carrying equipment to be used for surface levelling when casting concrete floors and roofs.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described further with reference to the accompanying drawings.
FIG. 1 is a perspective view of a device in the form of a supporting and levelling element for supporting and adjusting the level of a construction.
FIGS. 2-4 are different plane views of the supporting and levelling element.
FIG. 5 is a side view of the supporting and levelling element according to FIG. 1 during receipt of a construction element in the form of a beam with rectangular cross section, before the beam has loaded the supporting and levelling element.
FIG. 6 is a side view of the supporting and levelling element supporting, inter alia, the beam according to FIG. 5 and illustrating the effect when the construction loads the supporting and levelling element.
FIG. 7 is a perspective view of two supporting and levelling elements supporting and loaded by a construction consi
