Description

  The present invention relates to a seal structure and an auxiliary gasket member that seal vertical joint portions of a plurality of window plates that are continuously provided along the outer surface of a casing.

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.

  An object of the present invention is to provide a sealing structure and an auxiliary gasket member that can improve the sealing performance of the vertical joints of a plurality of window plates that are continuously provided along the outer surface of the casing, and can also improve the design. Is to provide.

In order to solve the above-described problem, the invention described in claim 1 is, for example, as shown in FIG. 1 and FIG.

  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. A pair of auxiliary gasket members 2, 2 provided on the side end portions 1 a, 1 a of the window glass materials 1, 1 a, respectively, and the vertical joint portions a of the plurality of window glass materials 1, 1 provided continuously. Is sealed by a main seal member or the like which will be described later provided between the outer surface of the window glass material 1 and the inner surfaces 1e and 1e of the window glass materials 1 and 1.

  As shown in FIG. 1, a pair of PC outer walls, which are casings, are provided on the inner side of the vertical joint portion a of the window glass materials 1 and 1 so as to face each other. A pair of support members 3 and 3 made of an aluminum alloy or the like are fixed to the pair of PC outer walls, respectively, and the window glass materials 1 and 1 facing each other have a pair of support members 3 at their side end portions 1a and 1a, respectively. 3 is supported by 3. A pair of sealing materials (main seal members) 3b and 3b and a pair of spacers 3c and 3c are provided between the support member 3 and the inner surfaces 1e and 1e of the window glass materials 1 and 1, respectively. In addition, a pair of gasket members (main seal members) 3a and 3a having the same cross-sectional shape made of a rubber material such as chloroprene rubber are symmetric with respect to the supporting members 3 and 3 facing each other with the vertical joint portion a interposed therebetween. So as to be fixed. Further, a pair of auxiliary gasket members 2 and 2 having the same cross-sectional shape, which are similarly made of a rubber material such as chloroprene rubber, are symmetrical on the side end surfaces of the window glass materials 1 and 1 with the vertical joint portion a interposed therebetween. So that it is fixed.

  Here, the auxiliary 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. Thereby, since the auxiliary | assistant gasket member 2 and the thin-plate-shaped part 2d mentioned later become a substantially flush state with the outer surface 1f of the window glass material 1, the auxiliary gasket members 2 and 2 are outside to the vertical joint part a of the window glass materials 1 and 1. The protruding portion is not formed.

  The pair of auxiliary gasket members 2 and 2 are bonded to the side end surfaces of the window glass materials 1 and 1, respectively, and are formed so as to form approximately 90 degrees with the bonding surface portions 2a and 2a. 1 and 1 are provided with auxiliary bonding surface portions 2b and 2b bonded to the inner surfaces 1e and 1e, respectively. In the pair of auxiliary gasket members 2 and 2, the bonding surface portions 2 a and 2 a are bonded to the side end surfaces of the window glass materials 1 and 1, respectively, and the auxiliary bonding surface portions 2 b and 2 b are bonded to the inner surfaces 1 e and 1 e of the window glass materials 1 and 1, respectively. It is glued. The pair of auxiliary gasket members 2 and 2 are further formed in a thin plate shape extending from the pair of auxiliary adhesive surface portions 2b and 2b toward the opposite side end portions 1a and 1a, respectively, and are respectively formed on the front end portions to the outside.

Thin plate portions (auxiliary seal portions) 2d and 2d. In the bonding surface portions 2a and 2a, one row of bonding grooves 2a1 is formed to be bonded in a state where one surface of the double-sided adhesive tape 4 is inserted.

  The window glass materials 1 and 1 are disposed in a state where a pair of thin plate-like portions 2d and 2d overlap 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 auxiliary gasket member 2 used in the seal structure shown in FIG. 2 has an adhesion surface portion 2a and an auxiliary adhesion surface portion 2b because the window glass materials 1 and 1 are provided at the corners of the building. Is set to about 120 degrees.

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 a state in which the window glass materials 1 and 1 are disposed, a pair of gasket members 3a which are main seal members between the outer surface of the casing and the inner surfaces 1e and 1e of the window glass materials 1 and 1. 3a is in close contact with each other, and a pair of sealing materials 3b and 3b which are main seal members are provided. Further, the pair of thin plate-like portions 2d and 2d are in an overlapping state. Thus, a space 2e surrounded by these and the pair of thin plate-like portions 2d and 2d is formed on the outer side of the main seal member.

  In this state, entry of wind and rain from the outside is prevented by the main seal member. Further, when the pair of thin plate-like portions 2d and 2d overlap each other, the main seal member is prevented from being exposed to wind and rain, and a constant pressure is maintained in the space 2e. Further, when strong wind rain or the like acts on the pair of thin plate-like portions 2d and 2d in an overlapped state, the pair of thin plate-like portions 2d and 2d are separated from each other, and rainwater enters the space 2e. Thus, the pair of thin plate-like portions 2d and 2d are overlapped again by their elastic force, and a constant pressure is maintained. And most of the rainwater entering the space 2e is immediately discharged, but the remaining rainwater adhering to the inner surface of the gasket member acts on the pair of thin plate-like portions 2d, 2d during a fine weather or the like. Then, when the overlap between the pair of thin plate-like portions 2d and 2d is temporarily removed and a wind blows into the space 2e, the air is discharged so as to be pushed out from the space 2e where a constant pressure is maintained.

According to the present embodiment, the following effects can be obtained.
(1) A pair of gasket members 3a and 3a which are main seal members are in close contact with each other between the outer surface of the casing and the inner surface 1e of the window glass materials 1 and 1, and a pair of sealing materials which are main seal members 3b and 3b are provided. The pair of auxiliary gasket members 2 and 2 are provided at the side end portions 1a and 1a, respectively, and the pair of thin plate-like portions 2d and 2d are formed in a thin plate shape toward the opposite side end portion 1a. Has been. And in the arrangement | positioning state of the window glass materials 1 and 1, a pair of thin plate-shaped parts 2d and 2d are the states which mutually overlapped. Thus, a space 2e surrounded by the main seal member and the pair of thin plate-like portions 2d and 2d is formed on the outer side of the main seal member.

  In this state, entry of wind and rain from the outside is prevented by the main seal member. Further, when the pair of thin plate-like portions 2d and 2d overlap each other, the main seal member is prevented from being exposed to wind and rain, and a constant pressure is maintained in the space 2e. Further, when strong wind rain or the like acts on the pair of thin plate-like portions 2d and 2d in a state where they overlap each other, the pair of thin plate-like portions 2d and 2d are separated from each other, and rainwater enters the space 2e. In this state, the pair of thin plate-like portions 2d and 2d are overlapped again by their elastic force, and a constant pressure is maintained. And most of the rainwater entering the space 2e is immediately discharged, but the remaining rainwater adhering to the inner surface of the gasket member acts on the pair of thin plate-like portions 2d, 2d during a fine weather or the like. Then, when the overlap between the pair of thin plate-like portions 2d and 2d is temporarily removed and a wind blows into the space 2e, the air is discharged so as to be pushed out from the space 2e where a constant pressure is maintained.

  That is, the pair of thin plate-like portions 2d and 2d substantially prevent the main seal member from being exposed to wind and rain. In addition, even when rainwater enters the space 2e, the main seal member is not immersed in rainwater for a long period of time because it is discharged in a relatively short period as described above. As described above, the sealing performance can be improved.

(2) The auxiliary gasket member 2 can be fixed to the side end face of the window glass material 1 easily and inexpensively by the dry double-sided adhesive tape 4 having sealing performance. At this time, the auxiliary gasket member 2 is bonded to the side end surface of the window glass material 1 so that the thin plate-like portion 2 d is substantially flush with the outer surface 1 f of the window glass material 1. The protrusion part to the outside is not formed in the vertical joint 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.

  For example, in the present embodiment, the gasket member 2 is adhered to the side end surface of the window glass material 1 by the dry double-sided adhesive tape 4, but may be performed by, for example, a wet adhesive.
