CS220912B1 - Fireproof panel - Google Patents

Abstract

The invention relates to the production and use of a solid, non-combustible and fire-resistant panel intended for particularly demanding protection of building structures (especially steel) against fire. The fire-resistant panel is made by joining two or more fire-resistant boards with an adhesive, porous, fire-resistant material made of water glass, expanded perlite, asbestos, diatomaceous earth and sodium or potassium fluorosilicate. In addition to construction, the subject panel can also be used in mechanical engineering for the production and cladding of thermal and technical equipment as well as in shipbuilding.

Description

220912

The invention relates to a fire resistant pan made by bonding fire resistant plates. The panel is designed for use in construction.

Spraying materials, plasters, refractory bricks and thatched materials are used to protect steel structures against fire.

Each of these materials has advantages and disadvantages. The advantage of spray booths and plasters is the possibility to spray or plaster OK directly. The advantage is particularly appreciated in protecting the mesh of complex shapes. The disadvantage of this method of O-protection is the difficult, lengthy technology. Several layers are usually applied to OK, with the previous layer being cured.

Obmurovka bricks are lengthy and take up a lot of space.

A common disadvantage of the aforementioned methods of protecting the OK is the wet process which is undesirable on the construction site.

Thatch fireproof materials have the advantage of dry assembly, high productivity at relatively low demands. Given the advantages of thatch materials, these materials are preferred whenever possible in the protection of mesh. In the case of a requirement, the protection time is longer OK, a double or several multiple fire-resistant boards must be made, which prolongs the tile work and makes it difficult.

The last mentioned disadvantage of thatch materials was partly solved by production panels composed of two fireproof boxes, among which is sealed a special component of two corrugated aluminum foils.

The disadvantage of these panels is the relatively high consumption of the narrow-profile aluminum foil, the low strength of the panel for cracking, and the relatively high waste in the handling and cutting of the boards to a smaller size.

The aforementioned drawbacks of thatch fire-resistant materials in the assembly and use as a fire protection device of OK eliminate the present invention - fire resistant panel.

The fire resistant panel is a rigid, non-combustible, fire resistant panel, composed of two or more fire resistant panels bonded with an adhesive, porous, fireproof material.

The fireproof panel produced by the proposed technology acquires, compared to the materials used, new and higher utility properties that create a wider use for it.

The fire resistant panel increases the overall fire resistance of the used thatch materials, increases their strength, handling, volume stability and workability.

The panel ridge can be selected according to the time required to protect OK. Usually, it can be used with coarse fire-resistant panels of 20 to 40 mm. If desired, fireproof panels and more thicknesses can be produced.

Fire-resistant panels can be used not only to protect the fire against fire, as well as partition walls and partition walls on construction sites and in shipbuilding, flooring and underflooring, as cladding of thermo-technical equipment and materials for the production of fire doors.

The fireproof panel can be used in a case where a rigid, large-area fire cladding is required, preferably a dry assembly. Basic properties of fire resistance: - bending tensile strength min. 5 MPa, - density 600 to 900 kg / m3, - coefficient of thermal conductivity less than 0,135 W / mK, - surface dimensions basic 1000 x 1200mm, max. 3200 x 1200 mm, - thickness 20, 25, 30 mm.

The fireproof panel can be treated with conventional tools such as wood, i.e., hopping, grinding, milling, drilling, nailing, and the like can be surface-treated with wallpaper but also with conventional paint, i.e., paint, spray and roll painting.

The following materials are needed for the production of fire resistant panels: - fire resistant thatch, sodium or potassium waterglass (density approx. 36 ° Bé), exudated perlite, asbestos, diatomaceous earth, sodium or potassium fluorosilicate, well water.

Adhesive, fireproof mass is produced by thoroughly homogenizing the base materials according to the desired quality, e.g. d. aqueous glass, 2 wt. d. expanded perlite, or 3 wt. d. kieselguhr, 10 wt. d. asbestos, 5 wt. d. sodium fluorosilicate.

Adhesive, fireproof material is applied to cleaned thatch. The suckers are placed on top of each other so that they stick together with the sticky material, and then squeeze to the desired panel ridge. The pellets are laid flat on the wooden base. The top panel is pushed evenly over the flat weight1 600 - 1200 kg. A temperature of at least 10 ° C must be provided for solidifying the adhesive.

After 24 to 30 hours, the panels are wrapped in plastic foils, tied with steel tape or plastic tape. The panels thus produced are weighed into a warehouse or directly exposed. If desired, fire resistant panels can be cut dry to the respective molds.
