Description

[Detailed description of the invention] Fireproof window structure The present invention relates to openable multi-paned window structures, particularly F2O class fire resistant This relates to multi-paned glass windows that have a multi-layered glass structure, in which the frame in which the glass is fitted is connected to the window frame and the window. It is equipped with a shoji attached to the frame, and structurally it is a shoji fitted to the outside shoji on the outdoor side of the window structure. It has a sheet of glass and one or more sheets of glass fitted into an inner shoji on the indoor side of the window structure. It is equipped with an inner glass window unit.

The present invention also particularly relates to an interlocking multi-glazed window structure having F2O class fire resistance. , the structural member fitted with glass has a window frame fitted with a glass window unit. be.

Windows and other glazed structures that can be used in the event of a fire occurring inside a building structure The components must be at least fire resistant and at least capable of preventing the spread of fire. Must not be.

Special window structures with F2O class fire resistance are designed to withstand exposure to traffic for slightly longer than 30 minutes. It is known that it can withstand ordinary fires.

However, window structures are required to have a wide range of fire resistance for long periods of 30 minutes or more. Ru. This means that building walls can withstand fire damage for a long time, typically 30 minutes or more. In some cases, fire damage can be sustained for twice as long as the above-mentioned time, i.e. for one hour.

The only traditional attempt to achieve long-term fire resistance in building window structures is to use steel. Or use so-called fixed windows that cannot be opened and are made of other highly fire-resistant materials. It is to use it.

However, this window structure not only has an unsightly appearance but also is expensive to manufacture.

The object of the present invention is to provide a window frame and at least an inner shoji made of wood and at least one hour (in other words, achieve F2O class fire resistance standards) withstand “standard fire” The structure has a fire resistance standard that is the same as that required for the walls of the building in which the window structure is installed. The objective is to provide an openable multi-glazed window that can meet standards.

The "standard fire" referred to here is a fire that is precisely formed by installing the window structure of the present invention on a wall. An artificial fire is an artificial fire caused by an oil burner in a test room.An artificial fire is a fire. This specifies the rise in room temperature using the duration as the number of strokes. The specified room temperature is the first 5 The temperature rises to approximately 550℃ in minutes, and after approximately 10 minutes, the temperature rises to 650℃, and approximately 13 minutes have passed. Then, the temperature becomes 700℃, and after about 26 minutes, it becomes 800℃, and about 50 minutes have passed. It becomes 900℃. Moreover, after 60 minutes, the temperature becomes slightly higher than 920°C.

For the above purpose, the window frame and the inner shoji are made of wood, and the inner shoji has a metal tightening frame. The clamping frame is provided with an adjustable clamping force that seals the glass window unit. is tightly tightened along its edges, and the above-mentioned one glass plate and the sealed glass window are The glass plate on one side of the unit is a flat fire-resistant heat-treated silicate glass such as Vilan glass. Made of glass, the outer shoji is placed on the outside at a distance from the wooden inner shoji. It is a wooden window frame and a wooden window frame placed on the indoor side of the window structure. At least the exposed surface of each inner shoji is a multi-glazed window with a coating of fire-resistant paint. This is achieved through structures. The glass window unit installed on the indoor side of the window structure is , in addition to the silicate-based fire-resistant glass plate, placed inward at a distance from the fire-resistant glass plate. It can be provided with a regular window pane.

Alternatively, the glass window unit may be made of plain or unreinforced heat-treated silicon inside the window structure. It is equipped with one flat fire-resistant glass plate made of acid-based material, and a glass with low translucency is attached to the fire-resistant glass plate. sheets can be stacked on top of each other.

Therefore, the window structure of the present invention is a multi-glazed window structure, which includes one ordinary glass plate, Both the inside and outside glass panes of the window structure are made of triple-layer heat-treated silicate-based fire-resistant glass. Preferably it is a glass window.

The fire resistance of the window structure of the present invention is obtained by the two silicate glass plates, but the Fireproof paint and metal applied to the wooden window frame and the wooden inner shoji on the indoor side of the window structure This is further improved by the tightening frame.

For example, when heated to a high temperature of 150°C to 170°C, fire-resistant paint ``swells up''. It expands to form an insulating layer that protects the wood underneath.

The fire resistance of the window structure of the present invention is determined by the band that expands in the event of a fire, the connecting material, and the non-combustible seal. 0 These improvements of the invention are particularly set out in claim 4.6. It is. A preferred construction of the metal clamping frame is particularly specified in claim 5.6. 9 The window structure of the present invention may also include a wooden intermediate shoji as described in claim 7. can.

The hinges placed between the window frame and the inner shoji allow the mutually connected shoji to rotate around the window frame. If the shoji is installed in It is convenient to provide a connecting member that holds the The above is e.g. disclosed in claim 8.10. Achieved through structure.

The fire resistance of the window structure of the present invention can be achieved by appropriately selecting material dimensions according to claim 9. can be improved.

The inventive concept is limited to openable window structures according to claims 1 to 10. It is also applicable to the fitted multiple glass window structure based on claim 11. It is possible.

The present invention provides a simple means for producing F2O which is impermeable and has excellent gas and mechanical strength. It is possible to provide a window structure having a fire resistance of 100%.

The invention will be explained in more detail with reference to some embodiments and the accompanying drawings.
