Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass mounting structure for a fire door.

[0002]

2. Description of the Related Art As a fire door, for example, JP-A-5-12
As shown in Japanese Patent No. 5877, there is known a fireproof door frame composed of a fireproof upper frame, a fireproof lower frame, and left and right fireproof vertical frames, to which glass having excellent heat resistance is attached.

More specifically, the upper frame of fire, the lower frame of fire, and the vertical frame of left and right frames are formed by inwardly facing glass mounting recesses by attaching fireproof plates to both side surfaces and outer surfaces of a steel core. Then
An aluminum decorative material is attached to the outer surface of each fireproof plate, and the peripheral edge of the glass is inserted into the glass mounting recess of each fireproof frame and supported by a fireproof sealant to support the glass. Installed on.

[0004]

With the above-mentioned fire door, the appearance design can be improved by the aluminum decorative material, and with the glass mounting structure, the peripheral edge of the glass is the recess for glass mounting of each fire fence. Although it can be securely supported with a fireproof sealant, it can be installed, but since the glass mounting recesses of the upper fireproof frame, the lower fireproof frame, and the left and right vertical fireproof frame are continuous for 4 times, the glass must be assembled after the fire door frame is assembled. The glass cannot be replaced because it cannot be attached or removed.

Therefore, an object of the present invention is to provide a glass mounting structure for a fire door which can solve the above-mentioned problems.

[0006]

[Means for Solving the Problems] Each of the fire stiles constituting a fire door frame of a fire door is provided with an inwardly facing glass mounting recess by attaching a fireproof plate to the indoor side surface and the outdoor side surface of a steel reinforcing core material. The outer surface of the fireproof frame is covered with an aluminum interior decorative material and an aluminum exterior decorative material. The inner peripheral portion is located outside the inner peripheral portion of the refractory plate and the decorative material on the outdoor side, and a steel retaining ridge is detachably attached to the inner peripheral portion of the refractory material on the indoor side of the decorative material on the indoor side. A decorative rim made of aluminum is detachably attached to the inner peripheral part of the material to cover the outer surface of the holding rim to form a recess for mounting glass. The glass mounting recess of the frame has 4 glass parts with excellent fire resistance. Fire door glass mounting structure is supported by Lumpur material.

[0007]

[Operation] After assembling the fire door frame, the retaining rim and the decorative ledge are attached to form the recess for glass installation. After the fire door frame is assembled, the glass is attached and removed to replace the glass of the fire door. Also, when the aluminum decorative rim is melted in the event of a fire, the steel holding rim holds the glass, so the glass does not come off. Further, the holding rim made of steel is covered with the decorative rim made of aluminum, so that the appearance of the fire door has a good appearance.
