Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an improvement in the push-pull structure of a curtain wall that can reduce the appearance size of the curtain wall.

<Prior Art> A conventional pressing structure for a curtain wall will be described with reference to FIGS. 3 and 4.

FIG. 3 is an external view of the curtain wall, in which 1 is a vertical member that constitutes the sash frame, 2 is its lateral member, and 3 is glass. FIG. 4 is a sectional view taken along the line AA of FIG.
The outer edge of the hollow frame 4 that constitutes the
Is connected to a hook-shaped flange and is screwed, and a pusher bar 6 is attached to the pusher bar mounting bar 5.

The presser flap 6 has a substantially T-shaped cross section, and the flange portion 8 is attached to the flange portion 7 projecting from the presser flap mounting bar 5 by hook-shaped flange coupling to form a glass groove, and the glass 3 is a sealing material 9 or the like. It is designed to be inserted through. 10 is a drainage hole in the glass groove.

<Problems to be Solved by the Invention> Since the conventional push-pull structure of the curtain wall is configured as described above, it is preferable that the external appearance dimension a of the lateral member 2 of the curtain wall which is visible from the outside of the building is small. ,
If it is made smaller, the distance b between the flange portion 7 of the pusher mounting bar 5 and the flange portion 8 of the pusher 6 forming the bottom surface of the glass 3 and the bottom of the glass groove becomes smaller, and the distance b is swayed by the shaking of the curtain wall when an earthquake occurs. Fluctuates, and the end surface 11 of the glass 3 may come into contact with the flange portion 7 or 8 to damage the glass.

Also, since the push-pitch 6 is attached via the push-pitch mounting bar 5,
Drainage hole with many components and complicated structure and high cost
There was a problem that 10 was visible from the outside.

The present invention has been proposed in order to solve these problems, and it is possible to reduce the appearance size of the curtain wall without reducing the distance between the glass end face and the glass groove bottom face, and to eliminate the need for a pusher bar. It is an object of the present invention to obtain a curtain wall push-pull structure that allows the drainage holes to be hidden from the outside.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the push-pull structure of the curtain wall according to the present invention has L-shaped protrusions above and below the outer end surface of the hollow frame forming the transverse member of the curtain wall. The L-shaped flanges formed on the upper and lower ends of the indoor side flange of the H-shaped cross-section flange are attached to the protruding portion to attach the pressing blade, and the pressing-fitting direction of the L-shaped protruding portion is opposite to the fitting direction. A set screw that abuts the tip of the L-shaped flange to stop the falling of the pusher from the side is provided, and a cover that covers the outside of the drain hole in the upper glass groove provided on the outdoor flange of the presser is provided. It is characterized in that it is formed by integrally extending from the upper end of the outdoor side flange.

<Operation> Since the curtain wall presser structure according to the present invention is constructed as described above, the presser L-shaped flange is fitted to the L-shaped protrusion of the outer end surface of the hollow frame forming the lateral member. By doing so, the tab can be directly attached to the hollow frame and fixed with a set screw. Also, since the mounting part of the push-pull is formed on the indoor side flange and is removed from the glass groove,
It is possible to increase the distance between the bottom surface of the glass groove and the glass end surface, and as a result, it is possible to reduce the outer appearance dimension of the lateral member while sufficiently securing the above distance. Furthermore, since the outside of the drainage hole of the glass groove is covered with a cover,
The drain hole can be hidden from the outside.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 12 is a horizontal member of the curtain wall, which is constituted by a hollow frame 13. Reference numeral 14 is a pusher attached to the hollow frame 13, and reference numeral 15 is a glass fitted and attached to the pusher 14 via a sealing material 16 or the like.

The outer end of the hollow frame 13 has L-shaped protrusions on the top and bottom thereof.
17a and 17b are integrally formed to project. Further, the pusher tab 14 is formed in an H-shaped cross section, and L-shaped flanges 19a, 19b fitted to the L-shaped projecting portions 17a, 17b of the hollow frame 13 are formed at the upper and lower ends of the flange 18 on the indoor side. Is formed, and a drain hole 21 for discharging invading rainwater is provided at the bottom of the upper glass groove of the outdoor side flange 20, and a cover 22 integrally extends from the upper end of the outdoor side flange 20 so as to cover the outside. Has been formed.

Reference numeral 23 denotes a L-shaped protrusion of the hollow frame 13, which is screwed into a protrusion 17a on the opposite side of the push-fitting direction, and abuts against the tip of the L-shaped flange 19a of the push-edge 14 to fix the push-edge 14. It is a set screw.

In the above-mentioned structure, the push-pull 14 is first L-shaped as shown in FIG.
The L-shaped flange 19a is obliquely inserted into the L-shaped protrusion 17a, and then the L-shaped flange 19b is pushed into the L-shaped protrusion 17b and moved downward in the drawing to move the L-shaped protrusion 17a of the hollow frame 13 to the L-shaped protrusion 17a, After fitting with 17b, the push-out tab 14 can be directly attached to the hollow frame 13 by screwing in the set screw 23. Then, the glass 15 can be attached by fitting and mounting the glass 15 on the push tab 14 via the sealing material 16 or the like.

As described above, by directly attaching the push tab 14 to the hollow frame 13 by using the L-shaped flanges 19a and 19b formed on the indoor side flange 18, the push tab mounting bar can be eliminated and the glass can be removed. Edge surface 24 and bottom of glass groove 25
The distance b between and can be made larger than that of the conventional one by the amount by which the push-fitting attachment part is removed in the glass groove.
The glass end face 24 is also the bottom of the glass groove 25 due to shaking during an earthquake
It is possible to reduce the found size a while ensuring a distance b that does not allow the contact.

Further, since the drain hole 21 provided on the outdoor side flange 20 of the push-pull 14 is covered by the cover 22 formed integrally extending from the upper end of the outdoor side flange 20, the drain hole 21 is not visible from the outside. The appearance can be improved.

<Effect of the Invention> As described above, according to the curtain wall presser structure according to the present invention, since the presser bar is directly attached to the hollow frame, the presser bar mounting bar is not required, and the component parts are eliminated. It is possible to simplify the configuration and reduce the cost by reducing the number of the presser and because the mounting portion of the pusher is removed from inside the glass groove, it is possible to increase the distance between the glass end surface and the glass groove bottom surface, As a result, while maintaining a sufficient distance, it is possible to reduce the external dimension of the lateral member, and the drainage hole of the push-pull is covered with a cover so that it cannot be seen from the outside. Can be improved.
