Abstract
A device for receiving formwork elements used to manufacture concrete elements has a bearing static structure and a flat formwork joined therewith which can be driven to vibrate by an exciting device in order to compact the still-plastic concrete. The sound-insulating joining devices are inserted between the formwork shell and the static structure. The exciting device bypasses the joining device and acts directly or indirectly on the formwork shell.
Claims17
A device for receiving formwork elements for the manufacture of concrete structural parts, the device comprising:
- (A) a static carrying structure;
- (B) a formwork shell which 1) has a flat upper surface that forms means for directly supporting the concrete, and 2) defines means for being set in vibration;
- (C) an intermediate layer via which the formwork shell is supported on the static structure, the intermediate layer being formed from a sound-insulating and vibration-insulating viscoelastic material disposed between the static structure and the formwork shell;
- and
- (D) exciter means, bypassing the intermediate layer and engaging the formwork shell, for setting the formwork shell in vibration so as to compact still-plastic concrete supported directly thereon, and wherein the intermediate layer insulates the static structure from sound and vibrations in the formwork shell.
A device for receiving formwork elements for the manufacture of concrete structural parts, said device comprising:
- a static carrying structure;
- a formwork shell, said formwork shell 1) having an upper surface that forms means for directly supporting the concrete, 2) being connected to the static structure, and 3) defining first means for being set in vibration in order to compact the still plastic concrete;
- a sound-insulation connecting structure inserted between the formwork shell and the static structure;
- exciter means, bypassing the connecting structure, for engaging indirectly or directly on the formwork shell and for exciting vibrations in the formwork shell that compact still plastic concrete supported on the formwork shell, wherein the connecting structure includes a viscoelastic intermediate layer consisting of a sound-insulating and vibration-insulating material disposed between the static structure and the formwork shell.
