Definitions
- the invention relates to edge formwork for concrete slabs and concrete slabs for Buildings, especially with building partitions.
- Buildings such as double or row houses or parts of buildings through fire walls be separated to minimize the transmission of sound Partition between two walls and the concrete ceilings.
- the ceilings between the buildings be separated. Sound bridges are created by small rigid ones Connections between the two wall shells, such as through concrete, mortar, Adhesives, foam plastic or other hard materials.
- ceiling edge formwork has been produced between the concrete ceilings on two sides attached or a formwork attached later was removed.
- the object of the invention is to improve the transition area and to make it cheaper manufacture.
- the formwork ensures that only one formwork element must be used against which the concrete ceilings from two sides can be poured. It is a lost formwork, it can remain permanently in the component. This will reduce costs at Assembly saved. The costs for disassembly are completely eliminated.
- this slab edge formwork is combined in one element.
- This element comprises a core material which does not transmit the sound can, and two top layers that prevent fresh concrete from getting into the Joints of the element can penetrate.
- Stand on a head side of the element the cover layers over, at the other end the cover layers are set back, so that the joint is covered and fresh concrete is not in the butt joints can penetrate.
- In the lower area of the slab edge formwork there is an extension of the sound bridges that are used when gluing the element prevented from arising on the surface. Glue, mortar or This extension keeps concrete away from the two wall shells, so that no sound bridge can arise.
- Fig. 1 shows a formwork with a core 1, two-sided cover layers 2 and a web or extension 3.
- a butt joint is formed in that the cover layers 2 are arranged offset to the core 1 so that they over survive the core 1 and with the core of the adjacent formwork element overlap. This prevents concrete from entering the butt joint.
- the extension 3 is intended to transfer glue, mortar or concrete to the other Prevent wall side.
- the core 1 is preferably made of mineral fiber boards, the concrete pressure withstand when concreting. It can also be from others, preferably not flammable building materials exist that transmit the sound only minimally. To include impact sound insulation panels made of polystyrene particle foam, polypropylene foam or polyethylene foam.
- the squeeze (compressibility) of the element when concreting should be smaller than 6 mm on each side and overall less than 12 mm.
- the cover layer 2 preferably consists of building boards with a thickness of 0.2 to 20 mm, a fleece made of glass or plastic fibers or fiber cement.
- the top layer is attached to the core plate.
- the top layer has the function of fresh Not to let concrete penetrate into the butt joints and thus sound bridges to prevent.
- the building boards can preferably be made of thin cement-bound Fiberboard, 0.2 to 20 mm thick, exist.
- the supernatant N der Cover layer 2 can be the same or different on both sides.
- the extension 3 preferably consists of the same building material as the core 1.
- the extension can be sawn or milled homogeneously from the core plate 1.
- the extension can also be made separately and attached to the core plate become.
- the attachment is preferably made with adhesive.
- Dimension A indicates the total thickness of the element, dimension H the formwork height for the concrete ceiling and C and D the dimensions for the extension.
- the Dimension B indicates the thickness of the core and dimension L the length of the element.
- the installation of the formwork is shown in Fig. 2.
- the formwork is designated 10.
- the formwork has two functions:
Landscapes
- Physics & Mathematics (AREA)
- Acoustics & Sound (AREA)
- Engineering & Computer Science (AREA)
- Architecture (AREA)
- Electromagnetism (AREA)
- Civil Engineering (AREA)
- Structural Engineering (AREA)
