Definitions
- the invention relates to a recess box for shuttering recesses in concrete structures.
- EP-A-0 880 626 is a recess box in the form of a formwork quiver known that remains as lost formwork in the concrete ceiling.
- the quiver is placed on the lower formwork wall before concreting, so that when pouring the concrete ceiling, a cross-section corresponding to the quiver Recess is formed in the concrete ceiling.
- Such formwork quiver must be so stable that they can withstand the pressure of the concrete. So far the Formwork quiver generally made of sheet metal. A profile of the Sheet metal side walls for good interlocking in concrete.
- the object of the invention is the sound insulation at recesses in the concrete structure to improve.
- the recess box consists of a rubber granulate that with a binder, preferably a one-component prepolymer binder, is bound.
- a binder preferably a one-component prepolymer binder
- rubber granulate which is preferably a grain in the Size of 3 mm can be inexpensive recycling material be used. You get a solvent-free, health-friendly Product that stands out due to its aging, heat and cold resistance ideally suited as lost formwork and especially so has good soundproofing properties.
- the wall thickness is preferably about 2 to 5 cm. With a tamped density of the sound-absorbing material of 580 g / dm 3 , for example with a wall thickness of 32 mm, there is sound insulation of 38 dB.
- the grain size of the rubber granulate results in the outer surface of the Cut-out box a certain roughness, which is a good toothing in the concrete guaranteed.
- the elasticity of the material helps to avoid Shrinkage cracks in the concrete and also enables a good seal on the lower and upper formwork walls.
- the recess box can be formed by a one-piece molded part, can, however, optionally also be composed of plates connected by tongue and groove his.
- Figure 1 shows a cuboid recess box, which by a one-piece Molding 10 is formed from recycled rubber granules in a pre-polymer binder is bound.
- Molding 10 is formed from recycled rubber granules in a pre-polymer binder is bound.
- Have the walls 12 of the recess box a thickness of 4 cm and delimit one at the top and the bottom open rectangular recess 14, the dimensions of which depend on the size and number of Varies to be passed through the recess.
- this recess box is used for slab formwork, then so it is placed with its flat underside on the lower formwork wall, and the space surrounding the recess box within the ceiling circuit is filled with concrete up to the top of the recess box. After the concrete has set, the recess box remains firmly in place the recess so that the sound transmission into the cavity of the recess is effectively suppressed.
- FIG. 2 shows a recess box according to a modified embodiment, composed of plate-shaped wall elements 16, 18 is.
- the wall elements 16, 18 are made of the same material as in the Embodiment according to Figure 1 and each have a spring at one end 20 and in the area of the opposite end in their side surface one to the Tongue complementary groove 22 so that the wall elements after the groove / Put the spring principle together as shown.
- the recess box is replaced by the pending one Concrete stressed on compression. It is through the grooves and springs ensure firm cohesion of the wall elements.
- the embodiment according to FIG. 2 has the advantage that it is plate-shaped Wall elements 16, 18 with different dimensions in a variety of ways can be combined with each other to create recess boxes in different To form grid.
