Description

[Detailed description of the invention] [Industrial application field] The present invention is applied to the peripheral edge of a glass plate that is fitted and fixed in a groove of a sash frame and the inner wall surface of the groove in a fitted window used as a curtain wall. This structure is designed to airtightly and watertightly seal the gap between the sash frame and the inner wall surface of the groove. Loading a back-up material with a flexible thin tongue piece forming a bottom in the gap,
A glass plate fitting and fixing part is provided with a mounting part for attaching to the glass plate or the inner wall surface on the backup material, and a sealing material is filled in the gap so that it can be received by the thin tongue piece of the backup material. Regarding seal structure.

[Conventional technology]

Conventionally, deformation such as drooping of the thin tongue due to filling of the sealant is suppressed to ensure that the sealant is received by the thin tongue.
In order to ensure and facilitate the filling of the sealant and ensure the seal, as shown in FIG. The side end portion was configured to be received and supported by a support member 5D fixed to the glass plate 3 (for example, in the
Publication No. 15986). 1 is a sash frame, and 7 is a setting block that receives and supports the lower end of the glass plate 3.

However, when using the conventional structure, the back-up material is divided into two members, the member with the tongue piece and the support member, which are each attached separately, so the number of steps required for constructing the back-up material is two, and the workability is improved. Furthermore, due to mounting errors of each member, variations occur in the tongue receiving and supporting action of the support member, which tends to cause variations in the reception of the sealant. On the other hand, in conventional back-up materials, one end of the thin tongue piece is integrally connected to the attachment part to the inner wall of the sash, and in order to suppress deformation such as drooping of the thin tongue piece, the attachment part and the thin tongue piece are connected to each other. There was one in which a receiving part was integrally connected between the middle part of the tongue piece (Jikkosho).
56-2792).

However, in the conventional structure described above, the attachment part and the receiving part are integrated with the thin tongue piece,
Moreover, since the receiving part is integrally connected to the middle part of the thin tongue, deformation such as drooping of the thin tongue can be suppressed, but the flexibility of the thin tongue is lost and deformation occurs. As a result, when the thin tongue piece is compressed between the sash frame and the glass plate due to deformation of the sash frame, stress is applied to the glass plate, causing the glass plate to become distorted and the image reflected on the glass to be distorted. The drawback was that there was a risk of distortion.

[Problem that the invention attempts to solve]

The present invention was developed in view of these conventional drawbacks, and its purpose is to improve workability and stabilize the sealant receiving action, as well as to fit the glass plate so that the image reflected on the glass is less likely to be distorted. The object of the present invention is to provide a sealing structure for a fixed part.

[Means for solving problems]

The characteristic configuration of the sealing structure of the glass plate fitting and fixing part according to the present invention, which was taken to achieve the above object, is that the back-up material is provided with a receiving part that receives and supports the widthwise center part of the thin tongue piece, and The piece is integrally connected to only one of the upper end of the receiving portion or the upper end of the mounting portion, and the effects thereof are as follows.

[Effect]

The back-up material itself is equipped with a receiving part that receives and supports the thin tongue piece to prevent deformation of the thin tongue piece such as drooping due to filling of the sealant, reducing the number of installation steps required for the back-up material. is 1
Moreover, the receiving portion can be accurately positioned at the receiving and supporting portion with respect to the thin tongue piece. In addition, since the thin tongue piece is integrally connected to either the receiving part or the upper end of the mounting part, the thin tongue piece can be disposed between the sash frame and the glass plate due to distortion of the sash frame, etc. Even if it is compressed, for example, (a) if the thin tongue piece is integrally connected to the upper end of the mounting part, the thin tongue piece as a whole can flex significantly, and (b) the thin tongue piece can be attached to the receiving part. If they are integrally connected, the upper end of the receiving part can bend and allow the entire thin tongue to be displaced and deformed, so in either case, the compressive force that presses the thin tongue is As a result of being absorbed by the thin tongue piece, the stress acting on the glass plate through the thin tongue piece becomes smaller than when the amount of displacement or deflection of the thin tongue piece is small, making the glass plate less susceptible to distortion.

[Effect of idea]

As a result, it can be applied easily and quickly, and the sealant can be applied reliably using back-up materials.
A glass plate that allows stable reception and ensures that gaps are sealed with the desired sealant, and that the image reflected on the glass is unlikely to be distorted even if the sash frame is deformed or external force is applied to the sash frame. It was possible to provide a sealing structure for the fitting fixation part.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

1st Example In a fitted window constituting a curtain wall, as shown in FIGS. 1 and 2, the peripheral part of a glass plate 3 fitted and fixed in a groove 2 of a sash frame 1 and the inside of said groove 2 A back-up material having a structure for sealing the gap 4 between the wall surface 2A and the wall surface 2A in an airtight and watertight state, and forming a bottom in the gap 4 located closer to the gap opening side than the periphery of the glass plate. 5
At the same time, the gap 4 is filled with a sealing material 6 such as a silicone sealant for sealing the gap 4 in an airtight and watertight state so that it can be received by the backup material 5.

The glass plate 3 is placed on two setting blocks 7 made of elastic material that are appropriately spaced apart from each other in the glass plate width direction at the bottom of the groove 2 in the lower frame portion of the sash frame 1. It is positioned and fixed to the sash frame 1 by a positioning member 8 fitted into the center of the upper gap 4 in the width direction of the glass plate. A Teflon tape 9 is attached to the glass plate mounting surface of the setting block 7, and a Teflon tape 9 made of nylon or hard polyvinyl chloride is attached to the lower edge of the glass plate 3 to be placed on the setting block 7. A U-shaped sliding member 10 is elastically fitted. In other words, the glass plate 3 is made to slide smoothly in the groove width direction, making it easy to position the glass plate 3 in the groove width direction.

The backup material 5 is attached to the groove inner wall surface 2A.
A thin tongue protrudes toward the glass plate 3 side and forms a bottom in the gap 4 as described above, that is, receives the filling sealing material 6 at the end of the groove opening side of the plate-like mounting portion 5A that is adhesively fixed to the plate. Place piece 5B on glass plate 3.
An L-shaped receiving part 5C is attached to the mounting part 5A, and the L-shaped receiving part 5C is connected to the thin tongue piece 5B so that it does not touch the thin tongue piece 5B, and also comes into contact with the center part in the width direction of the thin tongue piece 5B to receive and support the center part in the width direction. It is made of a continuous structure made of elastic materials such as soft neoprene rubber with a hardness of about 60 degrees and polyvinyl chloride.

To explain the construction procedure, the backup material 5 is fixedly attached to the groove inner wall surface 2A of the sash frame 1, the setting block 7 is set at the bottom of the groove 2, the glass plate 3 is fitted and positioned, and then the positioning member is installed. 8 and attach the glass plate 3 to the sash frame 1
