Abstract

The invention relates to a machine anchorage for fastening heavy machinery, especially top-heavy machine tools, which is cast in the foundation and has elements for screwing the machine. The object of the invention is to provide an anchorage for mounting heavy machinery on an isolated floor / foundation, in particular a stable installation top-heavy machines and a compensation possibility occurring Toloranzen is to ensure the anchor bolts. According to the invention, this object is achieved in that a frame made of profile rails rests in the foundation on an insulating film and has a plurality of threaded nuts which are slidably arranged in anchor points of the foundation frame but against rotation and each anchor point is completed with a welded cover. The field of application of the invention relates to the attachment of heavy machinery on floors or foundations.

Title of the invention "Machine anchoring" Field of application of the invention

The invention relates to a machine anchorage for fastening heavy machinery, especially top-heavy machine tools, which is cast in the foundation and has elements for screwing the machine.

Characteristic of the known technical solutions

When installing machines, seepage oil often causes the foundations or storey ceilings to be destroyed. To protect these structures, in particular to maintain the sustainability of floor slabs and to eliminate the possibility of groundwater pollution in ground floor buildings, the laying of an insulating film under the floor screed is often necessary.

This insulation is used, for example, PVC film, but is only effective if it is not destroyed by the introduction of machine anchors.

Known is a machine anchorage (DE-PS 1,029,623), which allows the adjustment of the machine foot in all 3 levels of the room. For this purpose, a rotatable disc is arranged in a housing, which is height adjustable by means of threaded and kleinmbar. In addition, the disc has a diamtetrale guide groove in which a screw for fixing the machine base is arranged,

Another embodiment of this machine anchoring has · in said rotatable disc an additional exzen-. trically arranged disc for receiving the screw.

Although this machine anchoring can be embedded in the floor over the insulating film, but is not suitable for anchoring top-heavy machines. The forces can not be absorbed by the embedded anchors. In addition, a gauge for adjusting the anchorage corresponding to the anchor holes in the machine base would have to be additionally used, whereby these are used. Solution is very expensive.

Furthermore, an anchor bolt unit for machine attachment to foundations is known (DEs-OS 2,011 * 468), in which a bush-like armature housing is mounted in the foundation. This armature housing has in an extended part a non-rotatable threaded plate into which the anchor bolt is screwed. Threaded plate and anchor bolt can be moved in the housing limited or ' be moved to compensate for tolerances. If the anchor bolt holding the machine is tensioned, the threaded plate lies against a shoulder-like stop in the anchor housing.

Due to the required depth, this anchor bolt unit can not be used for foil insulated floor slabs. However, it offers the advantage that the anchor bolt can be screwed back down to floor level during machine assembly / disassembly, so that the ends of the anchor bolts do not protrude.

Explanation of the essence of the invention

The invention has as its object to provide a machine anchorage for attachment of heavy machinery, which is arranged in an insulated floor / foundation, a stable installation in particular, ensures top-heavy machines and provides a compensation possibility occurring tolerances for the anchor bolts. ,

According to the invention, this object is achieved in that a profiled rails existing foundation frame rests in the foundation on an insulating film and having a plurality of threaded nuts, which are displaceable in anchor points of the foundation frame

but are arranged against rotation and each anchor point is completed with a welded cover.

embodiment

The invention will be explained in more detail below with reference to exemplary embodiments, wherein the drawings represent the following:

Fig. 1 shows a foundation frame in double cross-section as plan view (for example, for top-heavy machine with 6 anchor points).

2 shows a cross section of the cast-in frame on insulating film in the region of an anchor point (section A-A).

Fig. 3 shows a cross section of the frame with visible cover made of matched, same profile material and attached machine (section B-B).

The machine anchoring according to Pig. 1 shows a foundation frame, which consists of a plurality of profiled rails 1 welded together, which have a U-shaped cross-section. In the rails 1 anchor points 2 are formed at different locations, corresponding to the machine to be anchored, which are closed by means welded Abdeckhauben3 from adapted, same profile material. The cover 3 has on the web side an enlarged, central opening 4, through which a screw 5 (machine screw) is introduced.

This screw 5 is screwed into a threaded nut 6, which is welded on all sides movable under the cover 3.

At each anchor parts 2 is a Gewautautter 6 under the. Cover 3 on all sides displaceable but arranged against rotation. ·

Fig. 2 shows a foundation frame according to section A-A

an insulating film 7 is located and cast in a known manner, a foundation 8 or in the screed a floor ceiling. Here, the upper edge of this foundation 8, on which 'is a machine to be fastened 9, approximately level with the upper edge of the foundation frame.

Fig. 3 shows a base frame according to section B-B with level screwed foot of the machine 9. The foundation frame is made according to the present in the foot of the machine 9 anchor holes, i. Each attachment hole is assigned a corresponding anchor point 2 in the foundation frame.

The threaded nut 6 is dimensioned in comparison to the clear space of the anchor point 2 so that it can be moved laterally and also has a certain height clearance. About the diagonal, the threaded nut 6 is so large that a rotation of the same, in the anchor point 2 (housing) is prevented.

It is necessary to weld the threaded nut 6 at each anchor point 2 under the cover 3 in the rail 1 relatively tight, so when embedding the foundation frame in the foundation 8 or in the floor screed a floor ceiling no mortar material can penetrate and thus a Set the threaded nut 6 is prevented. The introduced in the foundation 8 insulating film 7 is not damaged by the attachment of the machine 9 by means of screws 5 on the foundation frame, as this hur in the region of the anchor point 2 in the threaded nut 6 - which is under the welded cover 3 in the frame - engages and does not come into contact with the underlying insulating film 7.

The foundation frame ensures the secure mounting of the machine 9, whereby in particular top-heavy machine tools can be stably erected.
