Description

speed bump The invention relates to a threshold for supporting a frame and a fixed panel sash of a door or a window on a building structure, with an elongated threshold body which is provided for direct or indirect fastening to the building structure and has a surface, and with at least one connecting element to be inserted between the surface of the threshold body and an underside of the frame or the fixed panel sash, wherein the connecting element has an underside designed to be placed on the surface of the threshold body. The threshold of a door or window is typically embedded in the floor slab of a building in such a way that the surface of the threshold body or an intermediate profile attached to it is as flush as possible with the surface of the floor slab. The fixed panel sash can rest directly on the threshold body or on the aforementioned intermediate profile, which transfers the weight of the fixed panel sash to the sill body. A guide rail can also be arranged on the threshold body, along which a movable sash can be pushed in front of the fixed panel sash to create a passage. Connecting elements such as frame corner connectors, central sealing blocks, or similar attachments are intended for thresholds of the type mentioned above to provide a connection between the components of the frame or the fixed panel and the threshold body, and in particular to prevent moisture penetration into the building structure. For this purpose, a sealing foil or sealing plate is usually inserted between the connecting element and the threshold body during installation. Alternatively or additionally, after installation The joints can be sealed by applying sealant. Both sealing options are time-consuming and annoying for the person responsible for installation. It is an object of the invention to facilitate the sealing of speed bumps without compromising quality. The problem is solved by a threshold having the features of claim 1. According to the invention, a groove is formed in the underside of the connecting element, which groove extends along an edge region of the underside, wherein a sealing element made of an elastic material is injected into the groove, wherein the sealing element adheres in the groove and protrudes from the groove at least in an uncompressed state. Installation personnel do not need to carry a sealing element and position it correctly because the connecting element is already equipped with one at the factory. Since the sealing element protrudes from the groove and thus extends beyond the contact surface, it is compressed when the connecting element is pressed against the surface of the sleeper body. This, combined with the elasticity of the sealing material, results in a particularly reliable sealing effect. It has been shown that a suitable injected seal eliminates the need for separate sealing films or sealing plates. Preferably, the sealing element protrudes from the groove over the entire length of the groove, in particular by a uniform compression allowance so that the sealing effect is uniform. The sealing element can be made of a foamed sealing material. Foamed seals have been shown to be particularly efficient and cost-effective. Foamed sealing material can be applied directly to the component in question in a freely dosable, tool-free, seamless, and contour-accurate manner. Foam formation can occur chemically during or after application, meaning it can react to form an elastic foam seal. The foamed sealing material can be a two-component material. According to a special embodiment of the invention, the sealing element is formed from a polymer material, preferably from a silicone material or from a polyurethane material. The sealing element may have a round cross-section, in particular a circular or elliptical cross-section. Such a sealing element is easily manufactured by injection molding. It is preferred that the cross-section of the sealing element be uniform over the entire length of the groove. The groove can extend completely around the underside. This means the groove can extend along the entire outer edge of the underside of the connecting element. This reliably prevents moisture from penetrating between the connecting element and the sleeper body. The groove's course is not necessarily limited to the underside of the fastener. For example, the groove could run around a corner and thus extend to a side surface of the fastener. The groove may have at least one closed loop. For example, exactly one closed loop may be provided, running close to the edge of the underside. According to one embodiment of the invention, the groove has two closed loops arranged on either side of a drainage channel formed in the underside. The drainage channel can be used to drain water to the front of the threshold. This is particularly important for central sealing blocks. The loops arranged on either side of the drainage channel securely support and seal such a central sealing block against the th
