BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention forms a space between the horizontal members of upper and lower adjoining units of a curtain wall, the space having the outdoor side and the indoor side sealing material as constituent elements, and the air is provided on the outdoor side vertical wall portion of the space. The present invention relates to an isobaric curtain wall in which a hole is provided and a baffle material is provided at a position facing the air hole in the space.

Prior Art and Problems to be Solved by the Invention FIG.
FIG. 3 is a vertical cross-sectional view schematically showing the structure of a conventional equal pressure curtain wall, in which a gap is sealed between the lateral seal members 52 and the indoor seal member 53 between the horizontal members 50 and 51 of vertically adjacent units. Of the space 54, and air holes 55 and 56 are provided in the outdoor partition wall 55 of the space 54 in order to equalize the atmospheric pressure in the space 54 with the atmospheric pressure. The baffle material 57 that alleviates the impact of (shown by the arrow a) and softens the momentum of the rainwater mixed in the wind,
It is fixedly attached to the upper horizontal member 50 or the lower horizontal member 51 by welding or the like so that the surfaces slightly wider than the width of the air holes 55 face each other.

Such a constant pressure curtain wall has a high sealing effect due to the double sealing materials 52 and 53, and
Even if a storm blows against the curtain wall, the atmospheric pressure in the space 54 becomes equal to the external pressure, so the space 5
The discharge of rainwater accumulated in 4 will not be blocked due to atmospheric pressure. As a result, a large amount of water does not accumulate in the space 54 and does not enter the indoor side.

However, in such a conventional isobaric curtain wall, the baffle material 57 merely serves to buffer the air flow. For this reason, the pins are used to connect the vertically adjacent units. The present invention expands the function of the baffle material of such an isobaric curtain wall,
An object of the present invention is to provide a material that can be used as a reinforcing material for horizontal members of upper and lower units, and that can reduce the number of parts and facilitate construction.

SUMMARY OF THE INVENTION According to the present invention, a space provided with a sealing material on each of an outdoor side and an indoor side is formed between horizontal members of vertically adjacent units of a curtain wall, and an outdoor vertical wall portion of the space is formed. In an isobaric curtain wall in which an air hole is provided in the space, and a baffle material is provided at a position facing the air hole in the space, the horizontal member of the unit adjacent to the upper portion is supported on the upper end of the baffle material. Characterize.

Further, according to the present invention, a baffle member provided with a fitting groove below is fixed to a cross member of an upper unit of vertically adjacent units, and the fitting groove of the baffle member is fixed to the cross member of the lower unit. It is characterized in that the upper unit is fitted with a ridge formed upward on the upper surface through a cushioning material to prevent the upper unit from swaying.

[0007]

Since the isobaric curtain wall of the present invention supports the cross member of the upper unit by the baffle member as described above,
Bending and forward tilt between the mounting portions of the upper cross member to the body are prevented. Also, in the case where the baffle material fixed to the upper horizontal member is provided with a fitting groove, the fitting groove fits into the ridges of the lower horizontal member via a cushioning material, which results in vibration of the horizontal member of the upper unit. Is prevented.
