Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a flameproof structure for a window.

[Problems that conventional technology and ideas try to solve]

Generally, window frames and frames around shoji screens are made of aluminum or aluminum alloy shapes, but these have a low melting point, so in the event of a fire, they will melt due to the heat of the flames, causing flames. There was a problem that they could easily get in and cause a fire.

An object of the present invention is to solve these problems and provide a flameproof structure for a window that can prevent flames from entering and causing fires.

[Means to solve the problem]

In order to achieve the above object, the flameproof structure of the window according to the present invention is a flameproof structure of the window in which the window frame and the frame around the shoji are made of a material with a low melting point and high thermal conductivity such as aluminum. In the event of a fire, heat from the window frame or surrounding frame expands into the inside of the window frame frame, the inside of the frame around the shoji frame, and the gap formed between the two frames. A heat-expanding member is provided, and the expanded heat-expanding member surrounds and covers the molten window frame or the surrounding stile, and the interior of the window frame mold material, the inside of the surrounding stile mold material, and the gap. The structure is designed to seal the area and prevent fire from entering.

[Effect]

In the event of a flame, the window frames and frames around the shoji are made of materials with a low melting point and high thermal conductivity, so they will melt faster than other components, and will quickly transfer heat to the heating-expanding components. , the heating expansion member will expand.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In FIG. 1, 1 is a window frame formed of a metal shape material such as aluminum or aluminum alloy, and 2 is a vertical frame of the window frame. The concave grooves 5, 5 into which the edges are fitted are formed by protrusions 6 that protrude inwardly in the longitudinal direction, and a pair of L-shaped grooves 6 are provided on the outwardly side of the main body 3. Projecting pieces 7, 7 are provided so as to project from the bent portions inwardly and facing each other. Further, an outdoor surface portion 8 is formed by bending the outdoor edge of the main body portion 3 outward to the side, and an L-shaped bent portion 9 is formed at the edge of the outdoor surface portion 8. 9
As a result, a concave pocket is formed between the ALC panel (lightweight aerated concrete panel) 10 and the opening 11, and the caulking 13 is applied to improve watertightness.

Reference numeral 14 is a connecting member, which is arranged at a predetermined interval in the longitudinal direction of the vertical frame 2, and is welded to an opening reinforcing angle 15 that receives the ALC panel 10.
are connected at. Specifically, the connecting member 14 is
A connecting portion 18 having engaging groove portions 17, 17 at both ends that engage with the projecting pieces 7, 7 of the main body portion 3, and a mounting portion 19 protruding from the middle of the connecting portion 18 form a substantially T-shape. is formed in such a manner that the engagement groove portions 17, 17 and the protrusions 7, 7 are engaged, and the mounting portion 19 is
Welding 16,1 to angle 15 of ALC panel 10
6, and the vertical frame 2 is attached to the wall opening. Note that 20 is a mortar provided to cover the welds 16 and 16 portions. Although not shown, the mounting structure of the opposing vertical frames and upper and lower frames is also similar.

Reference numeral 21 denotes a heat-expanding member, which includes an inside 22 of the molding material of the window frame 1, an interior 24 of the molding material of the surrounding frame 23 of the shoji 4, and a gap 2 formed between the two molding materials.
5. Note that, like the window frame 1, the surrounding frame 23 is formed of a metal profile such as aluminum.

In the illustrated example, the inner surface of the outdoor surface part 8 of the window frame 1, the surrounding frame 2
3, both sides of the connecting piece part 26 provided in the longitudinal direction that partitions the interior 24 of the window frame 3, the groove part 5 into which the side edge (vertical stile) of the shoji 4 is fitted, and the engagement part between the connecting member 14 and the window frame 1. The heat-expanding member 21 is adhered via an adhesive layer 27 such as adhesive tape. Note that, as shown in FIG. 4, the heating expansion member 21 adhered to the concave groove portion 5 has a decorative paper 28 superimposed on its surface, and the shoji 4
By alleviating the impact caused by the opening and closing operations, the heating expansion member 21 is protected and the aesthetic effect is improved.

Specifically, as shown in FIG. 2, the thermal expansion member 21 is made by integrally bonding a thermal expansion agent 29 such as vermiculite or vermiculite to a ceramic fiber 30 via an organic binder. , about 300
When heated to a temperature higher than
The total thickness of the material is expanded, for example, by a factor of 5 to 8.

FIG. 3 shows the state in which the heating expansion member 21 is expanded, and when flames are applied during a fire, the window frame 1 and the surrounding frame 23, which are made of a material with a low melting point and high thermal conductivity such as aluminum, , which conducts heat more easily and melts more easily than other members constituting the window, so heat is quickly transferred to the heating expansion member 21 provided on the window frame 1 etc. before the flames affect other members. As a result, the heating expansion member 21 expands, and the inside 22 of the profile of the window frame 1 and the interior 2 of the profile of the surrounding frame 23 are expanded.
4, and the gap 25 are sealed, and even if a new gap is formed in each mold material due to melting of each mold material, the expanded heating expansion member 21 surrounds the window frame 1 to the surrounding frame 23. Because I am doing
It is possible to reliably isolate indoors and outdoors, and prevent fire from entering.

According to the embodiment of the present invention, since the ceramic fiber 30 is used as the constituent material of the heating expansion member 21, it has excellent thermal insulation and heat insulation effect, and has the advantage of not losing its elasticity even at high temperatures.

[Effect of idea]

Since the present invention is configured as described above, it produces the following effects.

In the event of a fire, the window frame 1 and surrounding frame 23 melt faster than other members, and heat is quickly transferred to the heating expansion member 21. As a result, the expanded heating expansion member 21 melts the frame 23 of the window frame 1. Even if the interior 22, the interior 24 of the mold material of the surrounding frame 23, and the gap 25 are sealed, and a new gap is formed in each mold material due to melting of each mold material, the expanded heating expansion member 21 Since the window frame 1 to the surrounding stile 23 are covered in an encircling manner, it is possible to reliably isolate the indoors from the outdoors, preventing the intrusion of fire, preventing the spread of fire, and preventing the outbreak of large flames. This is a useful device for preventing fires.
