Description

The present disclosure relates to sash structures.

A curtain wall structure is known in which sashes (sashes) are fitted between the upper and lower mullions of a support composed of mullions and mullions and between the left and right mullions. In such a curtain wall structure, outside air is introduced into the inside of the sash to reduce the pressure difference between the inside of the sash and the outside air in order to prevent water from entering the inside of the sash from the outdoors.

A drain hole for draining rainwater that has flowed down the sash is provided in the mulberry placed under the sash (see, for example, Patent Document 1). This drainage hole enables not only the discharge of rainwater but also the introduction of outside air into the interior of the mute. When outside air is introduced into the inside of the mesh through the drain hole, the outside air is introduced into the inside of the sash, and the pressure difference between the inside of the sash and the outside air can be reduced.

JP 2006-219831 A

Since the upper part of the sash is far from the drainage hole formed in the bottom of the sash, the outside air cannot be sufficiently introduced, and the pressure difference with the outside air may not be reduced.

An object of the present disclosure is to provide a sash structure capable of reducing the pressure difference between the inside and the outside air throughout the sash.

In order to achieve the above object, the sash structure according to the present disclosure has a support body with mullions and mulches, and a sash supported by the support body, and an upper side of the sash in the mullions. At least one of the portion adjacent to the sash and the mesh on the upper side of the sash is provided with an upper outside air introduction hole for introducing outside air into the inside.

As shown in FIG. 7 , when the sash 2 is fixed to the support 5 , the first upper outside air introduction hole 61 and the second upper outside air introduction hole 62 (see FIG. 4 ) are hidden by the sash 2 . Even if the first upper outside air introduction hole 61 and the second upper outside air introduction hole 62 are hidden by the sash 2, they are not completely blocked, and the first mullion 31 and the second Outside air can be introduced into the interior of the mullion 32 (see FIG. 4), that is, the first groove 314 of the first mullion 31 and the second groove 324 of the second mullion 32 (see FIG. 4). The outside air introduced into the first mullion 31 and the second mullion 32 is introduced into the sash 2 .

As shown in FIG. 8, the lower frame 25 of the sash 2 and the attachment 7 attached to the lower frame 25 are formed with sash drain holes 27 and 71 for draining water such as rainwater transmitted through the glass 22. there is Water passing through the sash drain holes 27 and 71 is discharged onto the second mesh 42 on the lower side. The second mesh 42 is formed with second mesh drainage holes 421-423 for discharging water discharged from the sash 2 to the outside. The second mesh drainage holes 421-423 can not only drain rain water, but also introduce outside air into the second mesh 42. As shown in FIG. Outside air introduced into the second mesh 42 through the second mesh drainage holes 421 to 423 is introduced into the sash 2 . The outside air introduced into the second mesh 42 is introduced directly into the sash 2 from the second mesh 42, or is introduced from the second mesh 42 into the first groove 314 of the first mullion 31 and the second mullion 32. is introduced into the sash 2 through the second groove portion 324 of the . The positions and number of the sash drain holes 27, 71 and the second non-mesh drain holes 421-423 may be set as appropriate.

The sash structure 1 is provided with a first upper outside air introduction hole 61 immediately below the first mesh 41 in the first mullion 31 , and a second upper outside air introduction hole 61 immediately below the first mesh 41 in the second mullion 32 .
