Since the heat expansion material is provided, the three sides of the panel body, ie, the upper side and the left and right vertical sides, can be covered with the heat expansion material in the event of a fire.
Since the lower side of the panel body is supported by a glass liner that melts in the event of a fire, the glass liner melts in the event of a fire, causing the panel body 25 to descend due to its own weight or the like, so that the lower side of the panel body becomes the bottom of the panel frontage of the lower horizontal member. The gap can be closed by coming into contact with the wall, and the fireproof performance can be maintained without providing a reinforcing member or the like for holding the panel body at the panel frontage.

Since no thermally expansive material is provided on the lower side of the panel body, the amount of thermally expansive material used can be reduced, and costs can be reduced while maintaining fireproof performance. It is possible to maintain good drainage while improving fire prevention performance without obstructing drainage due to drainage holes.
Furthermore, since the space for installing the parts does not become narrow on the lower side of the panel body, the degree of freedom in design can be improved.

In addition, since a long reinforcing member for supporting the edge of the glass is not provided in the frontage of the glass, the fireproof performance can be improved at a lower cost, and the fittings can be manufactured with a light weight.

In addition, since the fireproof panel of the panel body (multilayer panel) is placed on the outdoor side, and the heat expansion material on three sides is expanded toward the edge of the fireproof panel, the four circumferences are shielded on the outdoor side of the panel body. , the combustible gas generated between the inside and outside glass can be prevented from flowing out to the outside. For this reason, it is possible to suppress the flame generated outdoors from reaching the combustible gas generated between the inner and outer glass, thereby suppressing the spread of the fire.

In the event of a fire, the outdoor panel (fireproof panel) of the panel body descends, blocking the drainage hole formed in the panel opening of the lower horizontal member with the edge surface of the outdoor panel (fireproof panel). Communication with the space on the indoor side can be shielded.
In addition, by providing a drainage hole formed in the panel frontage of the lower horizontal member at or near the end of the lower horizontal member in the viewing direction, the thermally expansive material arranged on the vertical frame blocks the drainage hole of the lower horizontal member. may be made possible.
In addition, by arranging the drainage hole of the panel frontage on the outdoor side of the lower horizontal member, preferably on the outdoor side rather than the indoor side of the outdoor side panel (fireproof panel), when the fireproof panel falls in the event of a fire, the fireproof panel The drain hole of the lower horizontal member can be blocked more reliably by the lower surface.

Then, as seen in the fittings of the first, third and fifth embodiments, the thermal expansion materials f3 (f32) and f4 (f42) arranged in the panel frontage of the right and left vertical members are placed in the panel frontage. By arranging it on the prospective surface (bottom wall portion), the panel can be sandwiched so that both sides of the panel are compressed by the heat expansion material that expands due to heating in the event of a fire, and shielding performance can be improved.

In addition, as seen in the fittings of the first and second embodiments, by arranging the thermal expansion material arranged in the panel frontage of the upper horizontal member on the expected surface (bottom wall portion) of the panel frontage, the panel Together with the descent due to the body's own weight, the downward pressing force against the panel body can be increased, and the contact of the lower horizontal member of the lower surface of the panel body with the bottom wall can be strengthened.
In particular, in the fittings of the first embodiment, all three sides press the edge of the glass, and the glass can be clamped not only on the left and right sides, but also on the top and bottom, thereby improving shielding performance.

In addition, as seen in the fittings of the second, fourth and fifth embodiments, the thermal expansion materials f3 and f4 arranged in the panel frontage of the right and left vertical members are placed on the panel frontage surface (outdoor wall). part), and as seen in the fittings of the third, fourth and fifth embodiments, the heat expansion material arranged at the panel frontage of the upper horizontal member is placed on the panel frontage surface By disposing, the thermal expansion material expands between the bottom wall of the panel frontage and the edge surface of the panel body, so that the gap is reliably closed, and the expansion force of the filled expansion material causes the panel body to expand. can be pressed downward to improve shielding.

Furthermore, by arranging the thermally expansive material by means of a holder, the direction of expansion of the expansive material that expands from the opening of the holder is regulated and the direction of expansion is stabilized, and reliable closure by the thermally expansive material can be expected.

In addition, in the fire prevention fittings of the first to fourth embodiments, a holder is formed at the frontage of the panel, and the heat expansion material is set by the holder, but the heat expansion material is not limited to being installed by the holder. . For example, like the fireproof fittings of the fifth embodiment, the thermally expansive material may be attached to the frontage of the panel with an adhesive or the like, or may be fixed with screws or the like.
In addition, in the fittings of the above-described embodiments, the fireproof panel is arranged on the indoor side of the multilayer panel, but a multilayer panel in which the fireproof panel is arranged on the indoor side may be used.
Also, when using three or more multi-layer panels, only one panel at one end, such as only the outdoor end in the prospective direction, is an expensive fireproof panel, and all the remaining panels are relatively inexpensive. By using a non-fireproof panel, the effect can be exhibited at a low cost, which is preferable.

In addition, in the fittings of each of the above embodiments, the fireproof performance can be maintained by the thermal expansion material without arranging long reinforcing members at the panel frontages of the upper and lower stiles and the right and left vertical stiles. However, any of the frames other than the lower frame may be provided with, for example, a short auxiliary member or the like having a somewhat reinforcing function.
In addition, the member that holds the multilayer panel is not limited to the glazing channel, and the inside and outside of the panel may be sandwiched between the exterior bead and the interior bead, respectively, or adhesive such as curable caulking or hot melt. While adhering, the panel may be sandwiched inside and outside. Alternatively, the panel may be sandwiched by placing beads on one of the inside and outside of the panel and placing an adhesive on the other.

In addition, the example of the fittings in the above embodiment is just an example, and the fittings of the present invention are not limited to vertical sliding windows, but horizontal members (upper and lower frames and upper and lower frames) and vertical members (vertical stiles and vertical frames). If it is a fitting that is assembled on four sides and a panel body is arranged on the inner circumference, it can be adopted as a fitting structure such as various opening and closing windows or inset windows, and the type of fitting is not limited at all. is not.
