Definitions

  • the invention relates to a closure element for a fire protection sleeve.
  • Closure elements for fire protection sleeves are known from the prior art and serve to fix the fire protection sleeve on, for example, a pipe or secure.
  • cuffs which are limited to a very narrow diameter range, or so-called endless cuffs, which are adapted to the corresponding diameter of the tube and provided with a closure element that fixes the fire sleeve on the pipe.
  • the endless cuffs can be typically secured by wrapping with a strap on the pipe so that the strap acts as a closure element.
  • the metal housing is cut to the appropriate diameter of the pipe and placed around the fire protection collar enclosing the pipe.
  • the housing of many elements that are chain-like strung together, or made of a thin, flexible metal.
  • the joint which is formed by the two open ends of the metal housing is held together by means of additional fixing elements.
  • the metal housing completely encloses the fire protection sleeve and fixes it to the pipe. Since such a metal housing can be cut to a certain length, it is suitable for various pipe diameters.
  • the fire protection sleeve is secured on the pipe due to a jacket element which completely surrounds the fire protection collar and is provided with a closure element.
  • a closure element for a fire protection sleeve with a body, a connecting element and at least one locking element for a positive connection with an Intumeszenzstsammlung, wherein the body and the connecting element are made in one piece.
  • the invention is based on the idea to provide a closure similar to a belt with two buckles, wherein a buckle of the belt is represented by the closure element and the belt through the IntumeszenzstMail. Similar to the belt principle, it is provided according to the invention to place the intumescent strip around the element to be protected and then to fasten it by means of the two connecting elements, the connecting elements being connected to each other in a manner similar to two belt buckles.
  • one end of the locking element has an acute angle of at most 90 °.
  • the pointed shaped locking element ensures that it can penetrate more easily into the Intumeszenzstsammlung, so that only manual force to push the locking element is necessary, whereby the assembly is simplified.
  • the locking element is approximately perpendicular from the body. This ensures that the locking element does not bend when attached to the Intumeszenzstsammlung.
  • the locking element is employed with respect to a pulling direction of the closure element. By hiring the locking element, the locking element can more easily engage in the Intumeszenzstsammlung and get caught in this, what only a tensile force in a certain direction is necessary. By hooking a stronger connection of the closure element is made on the locking elements with the Intumeszenzstsammlung.
  • the locking element is made in one piece with the body.
  • the one-piece design of the locking element with the body has the advantage that no assembly of the closure element is necessary because the locking element does not have to be connected to the body by means of fastening means.
  • a higher power transmission from the locking element to the body is ensured by a one-piece design.
  • the locking element is bent out of the body.
  • the locking element is punched out of the body and thus made integral with the body, whereby material can be saved in the production of the closure element.
  • the locking element is cut out of the body. This means that the locking element is formed on an edge of the body and projects as a projection from the edge of the body. This embodiment of the locking element represents a particularly simple production of the locking element, since the contour of the closure element can be punched out of a metal sheet with the locking elements arranged on the edge.
  • the body preferably has at least one flexible tab arranged on one of its edges, which in the bent state partially encloses the intumescent strip.
  • the tab on the body can initially serve as a guide element to guide the closure element on the Intumeszenzstsammlung, wherein the tab later used as a securing tab for fixation.
  • the tab is bent and encloses the Intumeszenzstsammlung at least partially.
  • the body has a fastening section which serves for fastening the closure element to an attachment site, in particular a wall. Due to the configuration of a fastening section on the body, the closure element can be fastened directly to, for example, a wall in order to mount or fasten the closure element arranged on a fire protection collar.
  • the attachment portion is connected by means of a predetermined bending point with the body.
  • the body has a spring element, wherein the at least one locking element is arranged on the spring element.
  • the design of the spring element on the body basically ensures that the closure element can be pushed onto the Intumeszenzstsammlung without the locking elements engage in the Intumeszenzstsammlung. This can be done by means of the spring element in two ways.
  • the spring element can be designed in such a way that the locking element does not come into contact with the intumescent strip in its initial position and therefore also not when the closure element is pulled over the intumescent strip.
  • the spring element is connected under a Wnkel with the body.
  • the spring element can be designed in a plane with the body, wherein the locking element is employed on the spring element under a Wnkel against the mounting direction, which is preferably greater than 45 ° to the normal of the spring element.
  • the spring element with the locking element arranged thereon can slide resiliently over the intumescent strip during assembly. Due to the employed locking element engagement of the locking element in the IntumeszenzstMail of the closure element is not possible when the closure element is pushed in the longitudinal direction of the IntumeszenzstMail.
  • a locking element is provided which acts in a locking position, the spring element in a locking direction and thus prevents springing back of the spring element.
  • the spring element In the locked state of the closure element, the spring element is pressed by the blocking element in the locking direction, whereby the engaging with the IntumeszenzstMail locking element is mechanically secured.
  • the blocking element thus serves as an additional safeguard of the locking element.
  • the guide rails guide the blocking element on a defined insertion path, so that the spring element is acted upon in the locking position.
  • the guide rails hold the blocking element against the spring action of the spring element in a position acting on the spring element.
  • the closure element is designed hermaphroditic, so that the connecting element can be brought into engagement with the connecting element of a second closure element.
  • the closure element is accordingly to be used for both sides of the closure, whereby during assembly it is not necessary to make sure that both components of the closure are present, since there is only one type or component which can be used for both sides.
  • a fire protection element which consists of a fire protection sleeve and two closure elements of the aforementioned type, wherein the connecting element of a closure element with the connecting element of the other closure element engages and engage the locking elements of both closure elements in the IntumeszenzstMail.
  • the fire protection sleeve is thus effectively secured because the two ends of the fire protection sleeve or the IntumeszenzstMails are positively connected by the closure elements arranged thereon.
  • the fire protection collar is not positioned so that it is inserted into the annular gap between a wall bushing and, for example, a pipe, but is fixed after the wall bushing is a sheath of the Intumescent strip with a thermally stable material required to direct the intumescence in case of fire in the direction of the pipe or the wall bushing and to close the wall bushing.
  • the material is created so that the at least one locking element this simple, ie can penetrate without much effort.
  • Suitable materials are such that they do not lose their mechanical strength at temperatures occurring in the event of fire, such as glass fiber or other mineral materials.
  • the materials may be in the form of a fabric, mesh, fluence or as a thin solid material.
