Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a curtain wall having an appearance with emphasized horizontal frames.

(Prior art) Conventionally, as this type of curtain wall, a plurality of horizontal frames having glass fitting grooves on the upper and lower surfaces are fixed in a mullion with vertical intervals, and the glass fitting grooves are interposed between the horizontal frames. A structure is known in which a plurality of glass plates are fitted with left and right intervals, and the left and right adjacent ends 710 of the glass plates are joined to the tit with a sealing material without providing a vertical frame having a glass fitting groove. (Japanese Unexamined Patent Publication No. 56-59954). Although this conventional curtain wall was able to achieve an appearance with emphasized horizontal border lines, it has the disadvantage that water leaks immediately even if there is a slight defect in the sealing material that joins the left and right adjacent edges of the glass plate. was there.

(Problems to be Solved by the Invention) An object of the present invention is to improve the water damage resistance of the conventional implanted curtain wall as described above.

(Means for Solving the Problems) In order to achieve the above object, the present invention applies the isobaric principle and has the following configuration.

A plurality of horizontal frames having face material fitting grooves on the upper and lower surfaces are fixed at a required vertical interval to a plurality of mullions fixed at a required horizontal interval on the outside of the building.

Left and Right Vertical Ends A plurality of panels having mounting frames on the indoor side surfaces are placed next to each other with their left and right ends spaced apart from each other on the outdoor side of the mullion, and the space between the vertically adjacent horizontal frames is At the same time, the mounting frame is engaged with and supported by a supporting member fixed to the mullion, and further, the left and right adjacent ends of the face material are sealed with a sealing material. Stop.

A horizontal equal-pressure space communicating with the outside air is formed in the horizontal frame at least from the fitting groove at the lower end of the panel, and on the indoor side of the seal portion between the left and right adjacent ends of the panel.

It is characterized by the creation of a vertically equal pressure space that communicates with the outside air. Embodiments of the present invention will be described below with reference to the drawings.

The isobaric structure of the curtain wall as described above is as follows. First, in the horizontal frame (2)..., as shown in the third figure, there is an outside air inlet (28) on the outdoor side of the lower surface of the horizontal frame.
At the same time, the intermediate partition wall inside the horizontal frame from the outside air inlet (28) to the upper glass fitting groove (8) in this example is appropriately removed to ensure that the inside of the glass fitting groove (8) is equal to the outside air. This forms a lateral isobaric space (A) in which the pressure can be increased. On the other hand, in the pair of left and right supporting members (20), (20), the second

1b) is an example in which the substrate is removed and the other structures are substantially the same as in the second example.

(Effects of the Invention) According to the curtain wall emphasizing the horizontal frame of the present invention, by not using the vertical frame having glass fitting grooves to hold the left and right ends of the glass plate, an appearance that emphasizes the horizontal frame can be obtained. Due to the vertical and horizontal equal pressure spaces, water leakage can be prevented even if a defect occurs in the seal portion between the left and right adjacent ends of the panel material and the fitting portion into the horizontal frame.
