Definitions
- the invention relates to a supporting structure with a supporting element made of metal, which has a hollow profile, in the A fire protection agent is arranged in the cavity, the cavity of the structural element sealed liquid and pressure tight is the fire retardant from water in a liquid state which water is at least partially the cavity fills and at least one steam outlet valve on the structural element is provided.
- Such a structure is known from GB-A-1 265 141.
- the invention finds particular application in the context of fire protection of supporting structures and steel halls.
- a supporting structure with supporting elements made of metal Hollow profiles become known, the cavities of liquid and are sealed pressure-tight. Located in these cavities water as a fire protection agent in liquid form. To the Supporting elements are provided with temperature-controlled valves, through which steam can escape in the event of a fire. A satisfactory one Fire protection of particularly endangered elements of the structure and also the overlying roof parts not available (GB 1 265 141).
- the object of the invention is to design a structure for buildings with a relatively easy to do particularly effective fire protection, which all structural elements includes.
- the object is achieved in that the steam outlet valve Steam jet nozzle carries.
- the steam outlet valve prevents the build-up of excess pressure. from which the generated water vapor emerges. It serves the steam jet nozzle for directional lighting of particularly vulnerable Parts of the structural elements and / or an overlying Top, roof.
- the structural element can be assembled from hollow profiles Truss girder be formed and an upper chord and one Have lower chord through posts and diagonal struts are connected to each other, with all cavities of the upper chord, The lower flange, posts and struts are connected to each other, the lower flange is partially filled with water and the steam outlet valve is arranged on the top chord.
- all of the existing cavities can absorb the entire steam Flow through the interior of the lattice girder while cooling condense to water in parts of the carrier that have not yet been heated which flows back to the water in the lower chord can, which creates a cooling circuit in the truss trains.
- the steam jet nozzle pivoted on the steam outlet valve. This makes possible it is easy to adjust the direction of the steam jet that the endangered parts are hit.
- the drawing shows a supporting structure for a building, for example a steel construction hall, in a side view, in a simplified schematic Representation and partially cut open.
- the structure shown in the drawing consists of essentially from a vertical structural element, namely a prop 1, and a horizontal structural element in the form of a truss 2.
- a prop 1 a horizontal structural element in the form of a truss 2.
- Several such in Row or adjacent structures form that Support frame for an existing one, for example made of trapezoidal sheets (not shown) roof of the building.
- the support 1 is embedded in the floor 3.
- This structural element - The support 1 - consists of a hollow profile 4 Steel of circular or rectangular cross-section.
- the cylindrical or prismatic cavity 5 of this hollow profile 4 is sealed liquid and pressure tight everywhere, a sealing disc embedded near the bottom 3 also serves this purpose 6.
- the cavity 5 of the support 1 is completely filled with water 7 in filled liquid as a fire protection agent.
- the filling with water 7 happens with the help of a water inlet 8, the is provided above the bottom 3 on the hollow profile 4 and above a line piece 9 leads to the cavity 5.
- the water inlet 8 is with a shut-off valve 10 and with a flange 11 for Provide a water supply connection (not shown).
- the support 1 is at its upper end 12 with the truss 2 firmly connected, a flange connection is used for this 13.
- the cavity 5 of the support 1 is at its top End 12 with the cavities 5 'of the truss 2 for the Water 7 in fluid communication.
- the horizontal structure element is a multi-part truss made up of hollow sections 2.
- This truss 2 has a hollow Upper chord 14 and a hollow lower chord arranged parallel to it 15 on through hollow vertical posts 16 as well are connected by diagonal struts 17.
- Three of the truss girders 2 are 18 using flanges connected with each other. All cavities 5 'of top chord 14, Posts 16 and struts 17 are in fluid communication with one another.
- the lower flange 15 of the truss 2 is a hollow profile 19 of circular, rectangular or square cross-section and is made of steel.
- the formed by the hollow profile 19 Cavity 20 is, like the other cavities 5 ', on all sides liquid and pressure tight, serve this purpose for example the end plates 21.
- the corresponding is Upper chord 14 formed.
- the cavity 20 of the lower flange 15 of the horizontal truss 2 is partly with water up to a level 22 23 filled in the liquid state.
- This cavity 20th stands not only over between the top end 12 of the prop 1 and the lower flange 15 provided opening 24 with the Cavity 5 of the support 1, but also with the cavities 5 ' of the lower flange 15, the post 16 and the struts 17 and of the upper chord 14 in connection.
- a corrosion protection agent is added to the water 7, 23, which does not change the properties of the water.
- each steam outlet valve 25 carries a steam jet nozzle 26, the swiveling and thus adjustable adjustable is arranged.
- adjustable steam jet nozzles 26 from below directed to a roof of the building resting on the top chord 14 are these parts of the building by the outflowing Steam cooled, and at the same time the Oxygen required to ignite combustible material repressed. The roof is therefore very effective against destruction and crash secured.
