Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a continuous window structure in which a plurality of window plate members are laterally connected to a building window opening to support side edges of adjacent window plate members and to provide a support between these side edge portions. The present invention relates to a structure of a joint part for a window that seals joints.

[0002]

2. Description of the Related Art For example, as a structure of a joint part for a continuous window, two or more window plate members are attached to a window opening of a building in a lateral direction so as to seal joints along a cubic member of the window plate members. There is one described in Japanese Unexamined Patent Publication No. 8-303127.

[0003] 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. The gaskets are supported by a cubic member in contact with each other, and a water-stop seal portion is provided on the contact surface of these gaskets. 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.

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 a 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. Further, by providing the water-blocking seal portion, watertightness between the pair of gasket portions is maintained.

[0005]

In the joint structure described in the above-mentioned publication, the first and second elastically deformable amounts are small. Therefore, if the gasket parts are shifted in a direction away from each other, the water stopping effect is obtained. Greatly decreases. For this reason,
The joint cannot absorb the displacement in the surface direction of the window plate material (the direction along the window surface).

In addition, since a string-shaped sealing member is fitted into a sealing groove formed opposite to the contact surface of the gasket portion to form a water-stopping seal portion, when the opposed sealing groove is displaced, water-stopping is performed. No effect. Therefore, the range in which the displacement of the window plate material can be absorbed while exhibiting the watertight effect of the joint portion is limited.

[0007] The present invention solves the above-mentioned conventional problems, and can absorb not only the displacement in the thickness direction of the window plate material but also the displacement in the surface direction of the window plate material, and can obtain a reliable watertight effect. It is intended to provide a structure of a window joint.

[0008]

According to a first aspect of the present invention, there is provided a joint structure for a window, which is connected to a cubic member and faces each other with a gap between side edges of a window plate. A pair of gasket support members, and a pair of gaskets which are fitted and supported on the side edges of the window plate material, and which are connected and supported by the respective gasket support members, and a backup material is provided in the gap formed between the gasket support members. And a joint seal portion formed by filling a recess formed by the backup material and the gasket support member with a sealant.

The gasket and the gasket supporting member for supporting the side edges of the respective adjacent window plate members are separately formed, so that the relative movement of the window plate members in the thickness direction between the gaskets is allowed, and the gaskets are adjacent to each other. The displacement in the thickness direction of the window plate material can be absorbed.

Further, by attaching the pair of gasket support members to the cubic member with a gap provided therebetween, the gap in the surface direction of the window plate material can be absorbed in the gap. Further, since the joint seal portion formed between the gasket support members is formed by filling the sealant after assembling the window plate material, a reliable seal structure can be formed even if the gap greatly changes.

In addition, since rubber such as chloroprene rubber forming a gasket is incompatible with a silicone sealant or the like constituting a sealant, if these are brought into contact and sealed, the performance of the silicone sealant will be deteriorated. In, joint sealing can be performed without directly contacting the gasket and the sealant, so that stable performance can be exhibited.

According to the invention described in claim 2 of the present application, opposite side edges of a window plate member laterally connected to a building window opening are supported along a vertically extending cubic member and are adjacent to each other. A joint structure for a continuous window for sealing joints between window plate materials, the joint member being fixed to the cubic member and having a pair of gasket supports opposed to each other with a gap between side edge portions of the window plate material. A member and a pair of gaskets that are fitted and supported on the side edges of the window plate material and that are connected and supported to the respective gasket support members, and a fixed seal member is provided in the gap formed between the gasket support members. And a joint sealing portion for sealing the gap.

According to the invention described in claim 3 of the present application, an inner seal portion formed by mounting a resiliently deformable fixed seal member is provided inside the joint seal portion.

By providing the joint seals in a double manner, the watertightness of the joint is improved. The inner seal portion may be provided between the gasket support members, or may be provided between cubic members formed from opposed members as in the invention described in claim 4.

Also, as in the invention according to claim 5,
By configuring the inner seal portion with an elastic seal member having a hollow cross section, watertightness can be further improved. The hollow cross-sectional shape of the elastic seal member is not particularly limited, and various hollow shapes such as an annular cross section and a trapezoidal hollow cross section can be adopted.
