example 1

[0073] Example 1 - Symmetrical embodiment.

[0074]

[0075] *Temperature intensity

[0076] The laminated glass is manufactured as a cast-in-place method with a 10mm wide seal. The size is 1m x 2m. Fire resistance tests were carried out with laminated glass in a steel frame and glass bead attached towards the fire side. The outer panel facing the fire ruptured in the first minute of the test. Heat transfer of 12kW / m in 120 minutes 2 and thus remain below 15kW / m 2 limit value. The fire resistance of EW120 is thus achieved.

example 2

[0077] Example 2 - Symmetrical embodiment

[0078]

[0079] *Temperature intensity

[0080] The laminated glass was manufactured in a cast-in-place method and then cut into dimensions of 1 m x 2 m. Fire tests were carried out with laminated glass in a steel frame and glass bead on both sides. The outer panel facing the fire ruptured in the first minute of the test. Heat transfer of 11kW / m in 120 minutes 2 and thus remain below 15kW / m 2 limit value. The fire resistance of EW 120 is thus achieved.

example 3

[0081] Example 3 - Asymmetric embodiment

[0082]

[0083] *Temperature intensity

[0084] The laminated glass is manufactured as a cast-in-place method with a 10mm wide seal. The size is 1m x 2.3m. Fire tests were carried out with laminated glass in a steel frame and glass bead on both sides. The outer panel facing the fire ruptured in the first minute of the test. Heat transfer 2 and therefore keep below 15kW / m 2 limit value. The fire resistance of EW 120 is thus achieved.

Abstract

The invention relates to a laminated glass with fire protection effect, a fire protection system with this laminated glass, its use and production. The laminated glass, in relation to its thick ness,is characterized by a very well fire protection effect. Furthermore, the laminated glass can be cut, so that it is possible after the production thereof to cut it into the desired size.

Description

technical field [0001] The invention relates to a laminated glass with high fire resistance, a production method for the laminated glass and its use in the construction industry and in the vehicle and aircraft construction. The invention also relates to a fire protection system with laminated glass and frames. Background technique [0002] Laminated glass with high fire resistance is known from the prior art. These laminated glasses generally have an expansion layer in the form of a gel layer between two glass or glass-ceramic panes, which expands when exposed to fire and in this way achieves insulation against thermal radiation. In this case, two manufacturing variants of laminated glazing can in principle be distinguished. In a first variant, the intumescent material, which is still liquid during manufacture, is poured onto one of the plates, where it is allowed to dry. The laminated glazing thus obtained generally has a very thin gel layer (<2 mm) and often has a pl...
