Description

  The present invention relates to a seal structure and a gasket member that seal vertical joint portions of a plurality of window plates that are provided continuously.

For example, Patent Document 1 discloses a seal structure that seals vertical joint portions of a plurality of window plate members provided continuously to a window opening of a building.
As shown in FIG. 3, the seal structure of the vertical joint described in Patent Document 1 is a gasket support member 109a connected and fixed to a vertical member 106 along the vertical joint of the adjacent window plate materials 104a and 104b. 109b and a pair of gasket members 108a and 108b are provided so as to fit and support the opposite side end portions of the window plate materials 104a and 104b. A seal convex 112 having a hollow cross section is integrally formed on at least one of the pair of gasket members 108a and 108b.

In the technique described in Patent Document 1, since the elastic deformable range of the seal convex shape 112 having a hollow cross section is large, watertightness is absorbed while absorbing the deviation in the out-of-plane direction and the in-plane direction of the window plates 104a and 104b. The effect that can be secured is described. Further, by providing a plurality of the seal protrusions 112 at intervals, the water tightness is further enhanced, and a seal space 114 is formed between the seal protrusions 112, and the pressure acting from the outside is reduced by the seal space 114. The effect that watertightness is further enhanced is described.
JP-A-11-303522

By the way, in the seal structure described in the above publication, when the seal convex 112 is only one line, the seal convex 112 is elastically deformed, but it cannot be said that it is safe for waterproofing. In the example, two seal protrusions 112 are provided at intervals.
However, even in the double seal structure as described above, rainwater may enter the seal space 114 for some reason such as strong winds or earthquakes. In this case, it is possible to drain rainwater that has once entered the seal space 114 in the vertical direction, but if the seal space 114 is long in the vertical direction, it is difficult to drain rainwater in a short period of time. In this case, the seal convex 112 is exposed to rainwater for a relatively long time, and there is a concern about water leakage from this portion.

  Further, in the seal structure described in the above publication, since the gasket members 108a and 108b are fitted into the window plate materials 104a and 104b, the protruding portions by the gasket members 108a and 108b are provided outside the window plate materials 104a and 104b. Are often formed and are not preferable in terms of design.

  The subject of this invention is providing the seal structure and gasket member which make it possible to improve the design performance while improving the sealing performance of the vertical joint part of the several window-plate material provided in series.

In order to solve the above-described problem, the invention described in claim 1 is, for example, as shown in FIG. 1 and FIG.
A pair of window joints (window glass materials 1, 1) that are provided in series is provided with a pair of vertical joints a provided on opposite side edge portions 1 a, 1 a of adjacent window plate materials (window glass materials 1, 1). A sealing structure for sealing with gasket members 2 and 2,

And in the arrangement | positioning state of the said window board material, the said pair of main seal part is mutually in contact, and it has become the state which the said pair of auxiliary seal part mutually overlapped. Thus, a space surrounded by these and the pair of auxiliary seal portions is formed on the outer side of the pair of main seal portions.

  In this state, intrusion of wind and rain from the outside is prevented by the pair of main seal portions. Further, in a state where the pair of auxiliary seal portions overlap each other, the pair of main seal portions are prevented from being exposed to wind and rain, and a constant pressure is maintained in the space. Furthermore, when strong wind rain or the like acts on the pair of auxiliary seals in a state of overlapping each other, the pair of auxiliary seals is overlapped, and rainwater enters the space. The auxiliary seal portion is again overlapped by the elastic force, and a constant pressure is maintained. And most of the rainwater that has entered the space is immediately discharged, but the remaining rainwater adhering to the inner surface of the gasket member is subjected to strong winds or the like acting on the pair of auxiliary seal portions in fine weather. When the pair of auxiliary seal portions overlaps temporarily and wind blows into the space, the air is discharged so as to be pushed out of the space where a constant pressure is maintained.

The buffering force can be buffered, and the water can be discharged from the outside air introduction hole / drain port.
In addition, since the vertical joint portions of the plurality of window plate members provided in series are sealed by a pair of gasket members respectively provided at the opposite side end portions of these window plate materials, compared to conventional wet sealing Excellent anti-contamination performance. For example, in the case of conventional wet sealing, silicon oil drips due to a change in chemical properties and the wall becomes dirty, or dust or the like adheres to the silicon oil dripping on the wall. There is nothing.
Further, the side end face of the window plate material and the gasket member can be bonded easily and inexpensively by the dry double-sided adhesive tape.

As described above, the sealing performance can be improved.

  Hereinafter, with reference to FIG. 1 and FIG. 2, embodiment of the seal structure and gasket member which are this invention is described in detail.

  The seal structure according to the present invention is applied to the case where curtain wall type window glass materials (window plate materials) 1 and 1 are constructed on the building along the outer surface of the housing, as shown in FIGS. The vertical joint portion a of the plurality of window glass materials 1, 1 provided in series is sealed by a pair of gasket members 2, 2 provided respectively on the side end portions 1 a, 1 a opposed to the window glass materials 1, 1. It is.

  As shown in FIG. 1, the window glass materials 1 and 1 have a multilayer structure in which a sealing material 1d is filled and sealed outside a spacer 1c sandwiched between two glass plates 1b and 1b. On the inner side of the vertical joint portion a of the window glass materials 1, 1, these window glass materials 1, 1 are supported mainly at their upper and lower ends, and a vertical member 3 made of an aluminum alloy or the like is vertically arranged It is extended and provided. The standing member 3 supports the adjacent window glass materials 1 and 1 at their side ends 1a and 1a, respectively, and between the standing member 3 and the inner surface 1e of the window glass materials 1 and 1. A spacer 3a, a sealing material 3b, and the like are provided. A pair of gasket members 2 and 2 having the same cross-sectional shape made of a rubber material such as chloroprene rubber are fixed to the side end surfaces of the window glass materials 1 and 1 so as to be symmetrical with respect to the vertical joint portion a. ing.

  Here, the gasket member 2 is fixed to the side end surface of the window glass material 1 by a double-sided adhesive tape 4 having sealing performance. The gasket members 2 and 2 are bonded to the side end surfaces with a double-sided adhesive tape 4 so that a thin plate-like portion 2c, which will be described later, is substantially flush with the outer surface 1f of the window glass material 1. Projections to the outside are not formed on the vertical joints a of the materials 1 and 1. Since the window glass material 1 has a multilayer structure, a plurality of side end surfaces of the window glass material 1 are formed, and the adhesion between the side end surfaces and the gasket member 2 is improved.

  The pair of gasket members 2, 2 includes adhesive surface portions 2 a, 2 a that are bonded to the side end surfaces of the window glass materials 1, 1, respectively. A pair of convex portions (main seal portions) 2b, 2b formed in a hollow cross-section toward the other opposite side end portions 1a, 1a, respectively, and these convex portions 2b, 2b. And a pair of thin plate portions (auxiliary seal portions) 2c and 2c formed in a thin plate shape toward the other side end portions 1a and 1a facing each other. Two rows of adhesive grooves 2a1 are formed in the adhesive surface portions 2a and 2a to be bonded in a state where one surface of the double-sided adhesive tape 4 is inserted. In addition, since the pair of convex portions 2b and 2b are each formed in a hollow cross section, the elastic deformation range of the convex portions 2b and 2b is increased, and the out-of-plane direction of the window glass materials 1 and 1 is obtained. The watertightness can be secured while absorbing the displacement in the in-plane direction.

  The window glass materials 1 and 1 are disposed in a state where the pair of convex portions 2b and 2b are in close contact with each other and the pair of thin plate-like portions 2c and 2c are overlapped with each other.

  FIG. 2 is a plan view for sealing the vertical joint portion a of the two window glass materials 1 and 1 disposed substantially at right angles so as to form the corner of the curtain wall type building as described above. The seal structure according to the present invention is applied. The configuration of the seal structure shown in FIG. 2 is the same as the configuration of the seal structure shown in FIG. 1 except for whether it is a corner of a building or not. However, the gasket member 2 used for the seal structure shown in FIG. 2 is more than the gasket member 2 shown in FIG. The width is large and the distance between the convex portion 2b and the thin plate portion 2c is large.

Below, the mechanism by which the above-described seal structure seals the vertical joint portion a will be described.
In the sealing structure described above, in the state in which the window glass materials 1 and 1 are disposed, the pair of convex portions 2b and 2b of the pair of gasket members 2 and 2 are in close contact with each other, and the pair of thin plate-like portions 2c and 2c. Are overlapped with each other. Thereby, the space 2d enclosed by these and a pair of thin plate-shaped parts 2c and 2c is formed in the exterior side of a pair of convex-shaped parts 2b and 2b.

  In this state, entry of wind and rain from the outside is prevented by the pair of convex portions 2b and 2b. Further, in a state where the pair of thin plate-like parts 2c and 2c overlap each other, the pair of convex parts 2b and 2b are prevented from being exposed to wind and rain, and a constant pressure is maintained in the space 2d. Further, when strong wind rain or the like acts on the pair of thin plate-like portions 2c and 2c that are overlapped with each other, the pair of thin plate-like portions 2c and 2c are separated from each other, and rainwater enters the space 2d. Thus, the pair of thin plate-like portions 2c and 2c are overlapped again by their elastic force, and a constant pressure is maintained. And most of the rainwater that has entered the space 2d is immediately discharged, but the remaining rainwater adhering to the inner surface of the gasket member is subjected to strong winds or the like in the pair of thin plate-like portions 2c, 2c in a fine weather or the like. When the overlap between the pair of thin plate-like portions 2c and 2c is temporarily released and air is blown into the space 2d, the air is discharged so as to be pushed out of the space where a constant pressure is maintained.

According to the present embodiment, the following effects can be obtained.
(1) The pair of convex portions 2b and 2b provided in the pair of gasket members 2 and 2 are respectively formed toward the side end portions 1a and 1a of the window glass materials 1 and 1 opposite to each other, The thin plate-like portions 2c and 2c are formed in a thin plate shape toward the side end portions 1a and 1a of the window glass materials 1 and 1 opposite to each other at positions separated from the pair of convex portions 2b and 2b to the outside. ing. And in the arrangement | positioning state of the window glass materials 1 and 1, a pair of convex-shaped part 2b, 2b is mutually in contact, and it is in the state which a pair of thin-plate-shaped part 2c, 2c mutually overlapped. Thereby, the space 2d enclosed by these and a pair of thin plate-shaped parts 2c and 2c is formed in the exterior side of a pair of convex-shaped parts 2b and 2b.

  In this state, entry of wind and rain from the outside is prevented by the pair of convex portions 2b and 2b. Further, in a state where the pair of thin plate-like parts 2c and 2c overlap each other, the pair of convex parts 2b and 2b are prevented from being exposed to wind and rain, and a constant pressure is maintained in the space 2d. Further, when strong wind rain or the like acts on the pair of thin plate-like portions 2c and 2c that are overlapped with each other, the pair of thin plate-like portions 2c and 2c are separated from each other, and rainwater enters the space 2d. Thus, the pair of thin plate-like portions 2c and 2c are overlapped again by their elastic force, and a constant pressure is maintained. And most of the rainwater that has entered the space 2d is immediately discharged, but the remaining rainwater adhering to the inner surface of the gasket member is subjected to strong winds or the like in the pair of thin plate-like portions 2c, 2c in a fine weather or the like. When the overlap between the pair of thin plate-like portions 2c and 2c is temporarily released and air is blown into the space 2d, the air is discharged so as to be pushed out of the space where a constant pressure is maintained.

  That is, the pair of thin plate-like parts 2c and 2c substantially prevent the pair of convex parts 2b and 2b from being exposed to wind and rain. Further, even if rainwater enters the space 2d, it is discharged in a relatively short period of time as described above, so that the pair of convex portions 2b and 2b are not immersed in rainwater for a long period of time. As described above, the sealing performance can be improved.

(2) The gasket member 2 can be fixed to the side end surface of the window glass material 1 easily and inexpensively by the dry double-sided adhesive tape 4 having sealing performance. In this case, since the window glass material 1 has a multilayer structure, a plurality of side end surfaces of the window glass material 1 are formed, and the adhesion between the side end surfaces and the gasket member 2 can be improved. At this time, the gasket member 2 is bonded to the side end surface of the window glass material 1 so that the thin plate-like portion 2 c is substantially flush with the outer surface 1 f of the window glass material 1. The protrusion part to the exterior side is not formed in the part a. Therefore, the designability can be improved.

  It should be noted that the present invention is not limited to the present embodiment, and arbitrary modifications can be made without departing from the spirit of the present invention.
