Description

  The present invention relates to a glazing channel attached to a peripheral portion of a glass panel constituting a window glass of a building, a glass panel having the glazing attached thereto, and a glass panel to which the glass panel is attached to the sash through the glazing channel. It relates to the mounting structure.

  When the double glazing is attached to a sash of a building, a glazing channel (also referred to as a grechant, an attachment, or a bead material) is attached to a peripheral portion thereof. The glazing channel is formed in a substantially U-shaped cross section and is attached to the peripheral edge of the multilayer glass. Of the peripheral edge, the glazing channel attached to the bottom is required to discharge moisture that has entered from the gap with the double-glazed glass to the outside, and various proposals have been made for the discharging means. For example, in the glazing channel described in Patent Document 1, a drain hole is formed in the bottom wall portion, and a drainage space is provided between the drain hole and the bottom of the multilayer glass. According to Patent Document 1, moisture that has entered from the gap between the double-glazed glass and the glazing channel is drained from the drain hole through the drainage space. Therefore, it is possible to prevent the moisture from adhering to the bottom of the multilayer glass and the deterioration of the multilayer glass sealing material.

  By the way, the recent glazing channel has a structure in which a hard material and a soft material are combined in order to improve the mounting property to the double-glazed glass, and polyvinyl chloride is generally used as the material. Polyvinyl chloride is capable of simultaneously molding a hard material and a soft material, but has a problem that the usable temperature is low. For this reason, when multi-layer glass is installed in a building opening using a glazing channel made of polyvinyl chloride, the glazing channel softens and melts in a high-temperature environment such as a fire, and the multi-layer glass is separated from the glazing channel. However, it does not meet the fire protection requirements for building fire doors.

  Patent Document 2 proposes that a glazing channel that can be used for a fireproof sash is composed of a soft material made of a resin or rubber having a heat resistance of 130 ° C. and a hard material having a substantially U-shaped cross section. Yes.

By the way, buildings and condominiums that are positioned as buildings with high fire resistance performance are equipped with fire-proofing facilities that have flame-shielding performance in the area where there is a risk of fire spread of the opening (Building Standard Act Article 9 No. 9 It is obliged to install fire prevention equipment specified by the Cabinet and other government ordinances, and Article 109-2 (technical standards concerning flameproof performance)) of the Building Standards Law Enforcement Ordinance. A fire door approved by the Minister of Land, Infrastructure, Transport and Tourism based on Article 2-9 of the Building Standards Act, which has the performance specified by Article 109-2 of the Building Standards Act Enforcement Ordinance. According to the explanation of the applied standard specifications (Non-Patent Document 1), when using a softening and melting material such as polyvinyl chloride for the setting block, the bottom edge of the glass is sheared to prevent the glass from sliding down. The distance from the upper end face of the fall prevention block is defined to be 3 mm or less.

  However, when the thickness of the bottom wall portion of the glazing channel is large, there arises a problem that the sliding amount of the glass panel increases by the thickness. For example, since the glazing channel of Patent Document 1 described above has a drainage space below the bottom of the multilayer glass, the thickness of the bottom wall portion of the glazing channel is large, and the multilayer glass is formed when the glazing channel is melted. It slides down significantly and does not meet the fire protection requirements for building fire doors.

  In order to satisfy the provisions of Non-Patent Document 1, it is necessary to reduce the thickness of the bottom wall portion of the glazing channel so that the distance between the lower end surface of the bottom of the multilayer glass and the sliding prevention block is 3 mm or less. Therefore, it is difficult to form a sufficient gap between the lower end surface of the bottom of the multilayer glass to which the glazing channel is attached and the bottom wall portion of the glazing channel, and as a result, moisture is accumulated in the glazing channel. There has been a problem that moisture adheres to the bottom of the glass and the sealing material of the multilayer glass deteriorates.

  Next, the operation of the glazing channel 10 according to the present invention will be described.

  As described above, the main body 32 of the glazing channel 10 is made of polyvinyl chloride. Since polyvinyl chloride has low heat resistance, the main body 32 made of polyvinyl chloride softens and melts under a high temperature environment such as a fire, and the glass panel 14 slides down. Therefore, in the case of a conventional glazing channel constituted only by polyvinyl chloride, the sliding amount of the glass panel 14 becomes large. In particular, when a drainage space is provided under the glass panel 14 to enhance drainage performance, the glass panel 14 is raised by the amount of the drainage space.

  On the other hand, the glazing channel 10 of the present embodiment is provided with heat-resistant members 34 and 34 corresponding to the lower part of the mounting position of the glass plates 10 and 10 constituting the glass panel 14. Therefore, even when the polyvinyl chloride main body 32 is softened and melted, the heat-resistant members 34 and 34 remain as they are, so that the glass plates 10 and 10 are supported by the heat-resistant members 34 and 34. Thereby, the amount of sliding down of the glass panel 14 is only the thickness of the main body 32 made of polyvinyl chloride (the thickness of the main body 32 made of polyvinyl chloride below the glass plate 20). The amount of sliding can be greatly reduced.

  Further, in the glazing channel of Patent Document 2, when assembling a channel material made of a hard material with a substantially U-shaped cross section and an inner soft material and / or an outer soft material, a soft material having a lower shape retention property than a hard material. However, the glazing channel 10 of the present embodiment is formed in the groove 32G formed on the lower surface of the bottom wall portion 32A made of a hard resin having a high shape retaining property. Since the rod-shaped heat-resistant member 34 formed in the same rectangular shape as the cross-sectional shape of the groove 32G is fitted and fixed, the workability when the heat-resistant member 34 is attached is excellent.
