SEALING DEVICE FOR SEALING A SHEET PILE PROFILE, AS WELL AS AN ASSEMBLY AND METHOD
A sealing device for sealing a sheet pile profile, including a sealing body including a shape complementary to a sheet pile profile, wherein the sealing device includes a casing, which casing envelops the sealing material in a gas-tight manner and wherein, in the casing, such an underpressure has been created that the sealing body is in a shrunken state, and wherein the sealing body is designed to expand into an expanded state when a gas is let into the casing up to an atmospheric pressure, as well as a method for producing an assembly of a sheet pile profile and a sealing device.
The invention relates to a sealing device for sealing a sheet pile profile, comprising a sealing body which comprises a shape complementary to a sheet pile profile.
Such a sealing device is known in practice, for filling the space between the top side of a vertical wall and a sheet pile profile extending transversely to this wall. In this application, the sheet pile profile is generally a roof slab having a sheet pile profile, which roof slab is placed over the vertical wall or is fastened to the top side of the vertical wall. The spaces between the sheet pile profile and the vertical wall need, inter alia, to be sealed to combat damp.
A drawback of the known sealing device is that during the installation operation and as a sheet pile profile is fastened to a vertical wall, the sheet pile profile becomes deformed. The result of this is that the shape of the spaces to be sealed between the sheet pile profile and the vertical wall changes. Hence, the shape of the known sealing device no longer corresponds exactly to the sheet pile profile, whereby (draught) openings between the sheet pile profile and the sealing device are formed.
From GB 2210399, a noise-damping element is known for a joint in a road.
From DE 1273777C, a seal for joints in concrete parts is known.
An object according to the invention is to provide a sealing device which connects well to a sheet pile profile, even if the sheet pile profile has become to some extent deformed.
This object is achieved with the sealing device according to the invention, having the features of Claim 1.
The effect of this is that the sealing device can be placed in a shrunken state into the space of a sheet pile profile. In this position, the gas-tight shell of the casing is pierced, for example by puncturing of the casing. By virtue of the fact that the sealing body is designed to expand, a gas, in this case air, will be drawn into casing until an atmospheric pressure prevails in the casing. As a result, the sealing body will take on the shape of the ribs of the trapezoidal shaped sheet pile profile, whereby a tight-fitting sealing of the sealing body on the sheet pile profile is achieved. As a result of the rupturing of the gas-tight shell, the sealing body thus proceeds to swell.
In one embodiment of the sealing device according to the invention, the sealing body comprises elastic material. The elastic material has the advantageous characteristic that this, enveloped by a gas-tight casing will shrink if there is an underpressure in the casing and will expand if a gas is let into the casing. The expansion of the sealing body can likewise be achieved by virtue of the sealing body comprising means which, when coming into contact with a gas, enter into a chemical reaction, with the result that the sealing body expands.
In a further embodiment of the sealing device according to the invention, the size of the sealing body in the shrunken state is between 30 and 15% smaller than in the expanded state. In practice, it can be seen that an advantageous tight-fitting sealing of the sheet pile profile is thereby achieved. Preferably, the size of the sealing body in the shrunken state is between 20 and 25% smaller than in the expanded state.
In a further embodiment of the sealing device according to the invention, the sealing device comprises rupturing means for rupturing the gas-tight shell of the casing.
The sealing body can comprise sound-insulating material. This is, inter alia, advantageous for the sound-insulating sealing of (a part of) a building. Furthermore, the sealing body and the casing can comprise a fire-resistant material. In a building, a fire is hence prevented from spreading through the spaces between the vertical wall and the sheet pile profile. The sealing body and the casing can here respectively comprise mineral wool and aluminium foil.
The invention further relates to an assembly of a sheet pile profile and a sealing device according to the invention. In one embodiment of the assembly according to the invention, the complementary shape of the sealing body in the expanded state is larger than the shape of the sheet pile profile. Here, the complementary shape of the sealing body in the expanded state is preferably between 5 and 10% larger than the shape of the sheet pile profile. The complementary shape of the sealing body in the shrunken state is preferably between 10 and 15% smaller than the shape of the sheet pile profile. In addition, the invention further relates to a building comprising the assembly according to the invention.
The invention also relates to a method for producing an assembly according to the invention, comprising the following steps:
-
- the provision of a vertical wall comprising a top side,
- the placement of a sheet pile profile on the top side of the wall such that the sheet pile profile extends transversely to the wall,
- the placement of a sealing device between the top side of the wall and the sheet pile profile, and
- the rupturing of the gas-tight shell of the casing.
This method can comprise the step of making a perforation in the casing.
The invention will be further explained in detail with reference to the appended drawings, in which:
The invention also relates to a sealing device, assembly, building and method comprising a feature, or a combination of more than one feature, described in this document and/or represented in the figures. It will be clear to the person skilled in the art that many variants of the sealing device, assembly, building and method according to the invention are possible without departing from the scope of protection described in this document and/or represented in the figures.
