A firestop collar () for sealing of openings, especially of line penetrations (), that pass through walls () or ceilings has a frame () and a block () of optionally intumescent material disposed therein, and is characterized in that an intumescent inlay () is disposed between the block () and the frame ().

Fire protection sleeve

A firestop collar for sealing of openings, especially of line penetrations, that pass through walls or ceilings, has a frame and a block of optionally intumescent material disposed therein, and is characterized in that the frame is of modular construction.

Firestop collar

A firestop collar for sealing of openings, especially of line penetrations, that pass through walls or ceilings, has a frame and a block of optionally intumescent material disposed therein.

The invention relates to a composition comprising: a binding agent based on an aqueous, or solvent-based polymer dispersion; fireproofing additives comprising a physically acting expanding agent and an ash-crust stabilizer; inorganic fibers; and a spherical filler. The invention also relates to the use of said composition as a sealing mass, in particular as a fireproofing sealing mass.

Fireproofing sealing mass and use thereof

The invention relates to a fire protection composition comprising: a binder based on an aqueous, or solvent-based polymer dispersion; fire protection additives comprising a physically acting expanding agent, a compound containing phosphorus, selected from among salts or esters of phosphorus oxyacids, and glass fiber; and an acid-resistant, inorganic filler. The invention also relates to the use of said composition as a sealing mass, in particular as a fire protection sealing mass.

A tool for creating a wall opening. The tool includes a hole saw; and a centering jig having a center axis, where the centering jig is constructed as a centering ring, into which the hole saw can be pushed at least partly, and in that both the hole saw and the centering ring have on their circumference an opening such that this can be pushed transverse to the center axis completely onto a line.

Keyhole saw

A line penetration is useful for routing lines through a building part. The line penetration includes: a jacket tube, a base part, which is disposed at a first axial end of the jacket tube and has a receiving space, surrounding a routing opening, for a firestop material, an annular, membrane-like sealing element, which is disposed at the first axial end of the jacket tube, and at least one sealing plug, which is disposed at a second end of the jacket tube.

Line leadthrough with integrated smoke stopper

An installation block for dry walls is disclosed. The installation block includes at least one through-hole for passing through a cable, pipe, or the like. The installation block also includes two installation block parts, which are joined together and have a separating plane T, which intersects with the at least one through-hole. Further, a dry wall and a method for installing an installation block are disclosed.

A method for producing an intumescent plastic molded part that consists of a reaction plastic which contains intumescent additives and glass fibers is disclosed. The method includes providing an additive mixture which is composed of the intumescent additives and the glass fibers and mixing the additive mixture and components of the reaction plastic, where a homogeneous mass is obtained. The homogeneous mass is introduced into an injection mold and the homogeneous mass is hardened in the injection mold. A injection molding system for producing the intumescent plastic molded part and an intumescent plastic molded part are also disclosed.
