2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei 8 (1996) discloses a structure of a continuous window joint for attaching two or more window panel members to a window opening of a building so as to be continuous in the lateral direction and sealing the joints of these window panel members.
There is one described in 303127.

The joint structure described in the above publication has a first gasket portion for fitting and supporting one adjacent window plate material and a second gasket portion for fitting and supporting the other window plate material. And a pair of gasket portions are brought into contact with each other and supported by a cubic member, and a waterproof seal portion is provided on the contact surface of these gasket portions. The water-stopping seal portion is configured such that a groove is formed on the surface in contact with the gasket, and a sealing member made of silicone sponge is fitted into the groove.

[0004] In the prior art, a gasket provided between adjacent window plate members is divided into a first gasket portion and a second gasket portion, so that a window is formed at the mating surface of these gasket portions. Relative movement in the thickness direction of the plate is allowed. For this reason, it is possible to absorb the displacement in the thickness direction of the window plate material due to dimensional accuracy, mounting error, and the like of the precast panel and the like provided around the window opening. In addition, by providing the water blocking seal portion, water tightness between the pair of gasket portions is also maintained.

However, when the displacement of the window plate material is large, it is difficult to absorb the displacement of the window plate material only by the elastic deformation of the gasket described in the above publication.

In order to solve the above problem, the joints are formed by fixing the upper and lower edges of the window plate material to the upper and lower edges of the window opening using gaskets, while filling a sealing material between adjacent window plate materials. Is also conceivable.

However, when the rubber material constituting the gasket is brought into contact with the sealing material for sealing, when the sealing material is filled with the compounding components such as the vulcanizing agent and the anti-aging agent for the rubber constituting the gasket. (Migration)
Problems such as a decrease in the adhesive performance of the sealing material and the strength after curing or discoloration are likely to occur.

According to the present invention, even when the displacement between the window plate members is large, the displacement can be absorbed, and even if the gasket and the sealing material are used in combination, the performance of the sealing material does not deteriorate and the discoloration does not occur. The present invention provides a structure of a joint part for a window and a gasket for a window used for the structure.

Means for Solving the Problems and Effects of the Invention The invention described in claim 1 of the present application supports a window plate material that is laterally connected to a building window opening, and also forms a joint between adjacent window plate materials. A structure of joints for continuous windows that seals, with a gasket that inserts and supports the upper and lower edges of each window plate along the upper and lower edges of the window opening, and fills the seal material between the side edges of adjacent window plates. And a metal plate is integrally joined to the axial end face of the gasket, and the joint seal and the gasket are connected via the metal plate.

[0010] In the present invention, since the joint between the adjacent window plates is sealed by filling the sealing material, even if the displacement of the window plates becomes large, it can be easily coped with. In particular, by providing the metal plate, the gasket does not come into contact with the filled sealing material. For this reason, there is no fear that the compounding components of the gasket migrate to the sealing material and impair the sealing performance of the sealing material.

The metal plate only needs to be formed so that at least the sealing material filled in the joint seal portion does not contact the end face of the gasket, and may be formed in a shape that covers a part or all of the end face of the gasket.

Further, by integrally joining the metal plate during the vulcanization molding of the gasket, the joining strength is increased, and the gasket does not peel off from the metal plate. Further, the water stopping performance at the joint interface between the gasket and the metal plate can be secured.

The material of the metal plate is not particularly limited as long as it can be integrally joined to the gasket. For example, various materials such as an iron plate, an aluminum plate, and a stainless steel plate can be adopted.

The present invention can also be applied to a vertically connected window. That is, the invention described in claim 2 is a structure of a joint portion for a continuous window that supports a window plate member that is vertically connected to a building window opening and seals a joint between adjacent window plate members. A gasket that fits and supports both side edges of each window plate material along both side edges of the window opening, and a joint seal portion formed by filling a seal material between upper and lower edges of adjacent window plate materials, A metal plate is integrally joined to an axial end surface of the gasket, and the joint seal portion and the gasket are connected via the metal plate.

In the invention described in claim 4 of the present application, the gasket is provided with a fitting groove for fitting and supporting an edge portion of the window plate material and a zipper groove for fitting a zipper, and the zipper is fitted in the zipper groove. Accordingly, the edge of the window plate material fitted in the fitting groove is elastically pressed.

By pressing and holding the window plate by the zipper, the window plate can be reliably supported by the gasket. Further, water tightness between the gasket and the glass plate can be ensured. When the portion of the gasket where the zipper groove is formed is connected to the joint seal portion, it is desirable to join the metal plate to the area including the zipper groove so that the components of the zipper do not transfer to the filling sealing material.
