Description

Description: TECHNICAL FIELD The present invention relates to a building window glass, and more particularly, to a sealing material without partitioning with a metal sash frame when attaching the window glass to an opening of an outer wall of a building. The present invention relates to a mounting structure in which a plurality of plate glasses are continuously arranged.

[Conventional technology]

Conventionally, the window glass for construction was attached using the plate glass using the metal sash. This window glass is the most reliable against wind, earthquake and rainwater.

However, when this metal sash is used, the plate glass is swallowed by the metal sash, so that the glass is partitioned one by one in appearance, which not only looks bad but also hinders the visibility. In particular, when the glass has a visible light reflection film, the glass partitioned into small pieces has a poor design appearance, and a wider mirror surface outer wall is desired.

Therefore, a method has been proposed in which, without using a metal sash, a plurality of sheet glasses are joined together through a weather seal and a mullion is arranged on the back surface of the joined portion to form a window glass.

FIG. 10 shows an example of using a metal mullion.

In the figure, reference numeral 1 denotes a plate glass continuous wall, which is continuously provided by joining a plurality of plate glasses 2 in a lateral direction through a weather seal 3. 4 is a metal mullion provided on the back surface of the joint of the weather seal 3 on the continuous plate glass wall 1, and the plate glass is provided through the structural seals 5, 5.
It is glued to the back of 2,2.

The plate glass continuous wall 1 configured as described above is used for each plate glass.
Since 2 and 2 form a butt joint by the weather seal 3, the design is satisfied. And since each plate glass 2 and 2 is joined by the weather seal 3, watertightness is provided. Further, since structural seals 5, 5 are provided between the plate glass 2 and the metal mullion 4, wind resistance is imparted.

However, the metal mullion 4 has a structural seal 5
Since the adhesion durability with and the long-term stability may not be ensured, the glass will be calculated as two-sided support, and not only will the glass become thicker and the design will be uneconomical, but the weight will increase. As a result, workability is reduced.

Therefore, as shown in FIG. 11, a glass made of marion has been proposed.

In the figure, 6 is a glass-made mullion, which is integrally joined with the glass plates 2 and 2 via a structural seal 7.

The continuous wall 1 of the plate glass thus configured has a structural seal 7 as compared with the case where the metal mullion is used.
Since it adheres to the glass surface, it can be expected to have some adhesion durability.

[Problems to be solved by the invention]

However, in this case, since the seal is a three-sided adhesive between the plate glasses 2 and the glass mullion 6, the glass mullion 6 becomes an obstacle when absorbing the displacement between the plate glasses 2, and the structural seal 7 is cracked. May enter.
In addition, since the sealing by the structural seal 7 is carried out on site, quality stability is lacking and time and labor are required. Therefore, when this method is adopted, regular inspection is an essential condition.

[Object of the Invention]

The present invention has been made to solve such conventional problems, and an object thereof is to provide a building window glass capable of imparting durability while simplifying joining of glass sheets. To do.

[Means for solving problems]

Architectural window glass according to the present invention, a plurality of plate glass having a rib formed in advance by adhering a plurality of plate glass to the inner wall surface on the side of the joint portion, each of which is continuously connected in the lateral direction via a weather seal, and to each plate glass. A weather seal is also inserted between the provided ribs.

[Operation of the invention]

In the present invention, since the glass plate is provided with ribs made of glass in advance, the assembling work is completed on site only by inserting a weather seal between the plate glasses to be joined and between these ribs. And the weather seal at each joint is
Since it is a two-sided adhesive, it follows the displacement and there is no risk of cracking.

Example of Invention

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged cross-sectional view of an essential part showing a window glass according to this embodiment, and FIG. 2 is a perspective view showing a state after construction of a building to which the window glass is applied.

In the figure, 10 is a continuous plate glass wall, and a plurality of plate glasses 11 are joined to each other through an external weather seal 12. Reference numeral 13 is a glass rib provided on the inner wall surface of the plate glass 11, and is constituted by joining a plurality of plate glasses 14 via a synthetic resin film 15. The rib 13 is attached to the glass sheet 11 in advance at the factory. Reference numeral 16 is an internal weather seal inserted between the ribs.

Next, the operation of this embodiment thus configured will be described.

First, as shown in FIG. 2, a glass support frame 21 is attached to the opening 20 of the building, and a desired number of plate glasses 11 are attached to the glass support frame 21. Next, the plate glass continuous wall 10 is formed by inserting the external weather seals 12 between the plate glasses 11. Further, on the rear surface of the portion of each external weather seal 12, an internal weather seal 16 is inserted and bonded between the glass ribs 13, 13 integrally provided on the rear surface of each plate glass 11, 11.

As described above, according to the present embodiment, by carrying the plate glass 11 to which the glass ribs 13 corresponding to the mullion are attached in advance to the construction site, it is possible to perform almost the same operation as the conventional bonding of the plate glasses to each other. Can set glass.
Then, the glass rib 13 is firmly adhered with the synthetic resin film 15, and is laminated in several layers, and is firmly adhered with the synthetic resin film 15 in the same manner as the glass surface, and the plate glass 11 and the rib 13 are adhered. And the ribs 13 are made of plate glass
Adhered to each other with 14 faces and a thin structural seal,
It is considered that the rib 13 and the plate glass 11 are mechanically separated. Further, the plate glass 11 integrally provided with the ribs 13 can secure sufficient wind resistance for a long period of time, provide a continuous glass surface, and can enhance designability. Further, the watertightness is provided by the outer weather seal 12 between the plate glasses 11 and the inner weather seal 16 between the ribs.

In FIG. 3, a thin layer structural seal 17 is provided on the bonding surface between the rib 13 and the plate glass 11 in FIG.

According to this example, the adhesive strength between the plate glass 11 and the ribs 13 is improved, and a stronger bonded state is secured.

FIG. 4 shows the rib 13 in FIG. 1 formed into a substantially trapezoidal shape, and the same effect as that of the embodiment of FIG. 1 can be obtained.
