Abstract

(57) [Abstract] [Purpose] To prevent the intrusion of rainwater through the joint seal between the sash lower frames by blocking the engaging grooves of the sash lower frames adjacent to each other. [Structure] An engagement groove 3 of a fit-and-kill panel 2 provided in a sash lower frame 1, that is, an end of the sash lower frame 1 is provided with a closing plate 12 to interrupt the engagement grooves 3. Even if rainwater enters the engaging groove 3 through the sealing material 11b, the rainwater does not flow into the engaging groove of the other adjacent sash lower frame due to the closing plate 12 and is discharged to the outside through the drainage hole 8 and the communication hole 10. It

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage device for a horizontal sash in a curtain wall.

[0002]

[Prior art]

 A curtain wall is provided with a fitting and killing panel corresponding to adjacent sash lower frames, and the fitting and killing panel is engaged with an engaging groove provided in the sash lower frame to make the fitting and killing panels continuous between PC panels. The engaging groove of each sash lower frame communicates with each other through a joint seal between the sash lower frames.

Therefore, rainwater that has entered the engagement groove due to damage to the sealing material between the fit-and-kill panel (glass) and the sash lower frame flows freely between the lower frames of the sash, and the bottom component piece of the engagement groove. The water is drained through the drain hole provided in the.

[0004]

[Problems to be solved by the device]

 According to the conventional example, rainwater is allowed to freely flow between the engaging grooves of the sash lower frames, so when the joint seal between the sash lower frames is damaged due to aging, etc. May invade

The present invention was devised for the purpose of providing such a drainage device without rain leakage.

[0006]

[Means for Solving the Problems]

 In a laterally passing sash of a curtain wall equipped with fitting and killing panels corresponding to adjacent sash lower frames, a closing plate is provided at the end of the sash lower frame, and the closing groove closes the engaging groove of the fitting and killing panel. At the same time, the bottom wall component of the engagement groove is provided with a drainage hole communicating with the outdoors.

【Example】

 The drawings show an embodiment of a drainage device for a horizontal sash in a curtain wall according to the present invention. In the curtain wall of the embodiment, glass panels (fitting and killing) supported by the horizontal sash are arranged for each layer of a high-rise building. However, the PC panels are arranged between the glass panels via the sash upper frame or the sash lower frame that constitutes the lateral sash, and between the lateral sash and the PC panel, between the glass panels and between the PC panels. Fig. 1 is a perspective sectional view, Fig. 2 is a partial cutaway perspective view of the sash lower frame end, Fig. 3 is a vertical sectional view, and Fig. 4 is an adjacent sash. It is the side view which removed and showed the lower frame and PC panel.

In the figure, 1 is a sash lower frame that constitutes a lateral sash, 2 is a glass panel engaged with an engaging groove 3 provided in the sash lower frame 1, and 4 is a PC panel, which are adjacent to each other. A joint seal 5 is interposed between each of the sash lower frame 1, the glass panel 2 and the PC panel 4.

The sash lower frame 1 includes the engagement groove 3 and a hollow portion 6 arranged immediately below the engagement groove 3, and a bottom wall constituent piece of the engagement groove 3 (an upper wall constituent piece of the hollow portion 6). 7, a drainage hole 8 is provided, the engaging groove 3 and the hollow portion 6 communicate with each other through the drainage hole 8, and the hollow portion 6 has a communication hole 10 provided in a bottom wall constituent piece 9 of the hollow portion 6. It communicates with the outdoors through.

Then, the glass panel 2 is engaged with the engaging groove 3 of the sash lower frame 1 so as to be sandwiched between the indoor and outdoor sealing members 11a and 11b, and the end portion of the engaging groove 3, that is, the sash. The closing plate 12 is screwed to the end surface of the lower frame 1, and the closing plate 12 makes the hollow portion 6 a partitioned chamber, while closing the lower part of the engaging groove 3 so that the engaging grooves 3 and 3 are adjacent to each other. The space is blocked.

An auxiliary seal 13 is arranged inside the closing plate 12 so as to surely prevent the inflow of water from the hollow portion 6 in the direction through the closing plate 12.

[0012]

[Effect of device]

 Since the present invention is configured as described above, rainwater that has entered the engaging groove does not enter the room through the joint seal between the sash lower frames, which is practical.

FIG. 1 is a perspective sectional view.

FIG. 2 is a partially cutaway perspective view of an end portion of a sash lower frame.

FIG. 3 is a vertical sectional view.

FIG. 4 is a side view showing a sash lower frame and a PC panel which are adjacent to each other.
