DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel holding structure which can prevent an aluminum material from being exposed by a surface cover material, can securely fix a ledge so that it does not come off, and can reduce the size of a panel.

[0002]

2. Description of the Related Art In a curtain wall, an aluminum material (including an aluminum alloy) is generally used for a window frame or a shoji frame for supporting a panel. In order to prevent the background from being exposed, there is known a panel in which the outdoor surface of the panel is supported by a resin or rubber gasket.

[0003] Specifically, for example, as shown in FIG.
A sawtooth-shaped engaging groove 42 is formed in the outdoor portion of the framing 40 or the meshless 41 constituting the frame material, and a gasket 43, 43,... The outer periphery of the glass G is pressed and held by the gaskets 43 by contacting the other piece in the engagement groove 42 to prevent the other piece from coming off. The back surface of the glass G is held by the auxiliary frame member 44.

However, in this panel holding mode, the cross-sectional dimension of the gasket 43 must be considerably large in order to prevent the glass from falling off during a negative pressure state (a pressure state acting from the indoor side to the outdoor side). However, there is a problem that the appearance is deteriorated because the amount of protrusion from the glass surface is large.

Japanese Patent Laid-Open Publication No. Hei 8-170392 discloses a structure in which a surface cover is attached to an outdoor surface of an aluminum ridge to solve the above-mentioned problem. Specifically, as shown in FIG. 8, a main frame 50 which is an extruded aluminum material, a step 51 formed on the inner peripheral side of the outdoor end of the main frame 50, and a step 5
1, an auxiliary frame 52, which is an extruded aluminum material, is fixed to the outdoor side surface of the main frame 50 so as to cover the outdoor side, and supports a panel peripheral portion with the step portion 51;
A non-metallic covering member 53 attached to the outdoor side surface of the auxiliary frame 52;
Main engaging portion between the locking groove 54 formed on the outdoor side surface and the locking portion 53a formed on the inner side surface of the base material of the covering member 53, and the width direction tip of the covering member 53 with respect to the main engaging portion. The auxiliary frame 52 is provided at two positions with the auxiliary engagement portion 53b provided at the shift portion.
There is disclosed a cosmetic sash engaged with the sash.

[0006]

However, even in the case of the invention described in Japanese Patent Application Laid-Open No. 8-170392, the engagement between the auxiliary frame 52 and the main frame 50 is performed by the two locking projections 55. , 56, and the packing 57 is inserted between the auxiliary frame 52 and the glass G, so that even if the packing 57 is prevented from coming off to some extent, the auxiliary frame 52 is not affected by vibration or external force. In some cases, the auxiliary frame 52 is likely to be disengaged when it moves together with the packing 57, and it is hard to say that the dropping prevention is complete.

On the other hand, in a curtain wall, a structure in which a window frame or a panel frame is inconspicuous and looks as if it is constituted entirely by panels tends to be more preferred. However, in the case of the above-described conventional example, since the fitting and locking portion 54 of the covering member 53 is formed on the outdoor side surface of the auxiliary frame 52, if the find size is at least as large as the width necessary for forming the fitting and locking portion. There are problems such as unavoidable.

Accordingly, a main object of the present invention is to provide various advantages such as preventing the aluminum material from being exposed by the surface cover material, securely fixing the ledge so as not to come off, and reducing the found size. An object of the present invention is to provide a panel holding section structure provided with a surface cover material.

[0009]

According to the present invention, a panel fitting groove is formed by a frame member and a pressing edge attached to the frame member. In the panel holding part structure in which the glazing gasket is sandwiched between the outdoor side wall of the ridge and the panel and the panel is supported, the ridged gasket extends integrally from the base end of the glazing gasket, and a sheet-shaped ridge cover material and A ridge detachment member is sequentially provided, and the frame material and the ridge are connected by engagement of locking pieces formed respectively, and the frame material and the ridge are outwardly directed along the panel surface by the frame material and the ridge. A ridge-slip retaining groove for opening is formed, and a sheet-shaped ridge cover material extending from the glazing gasket covers the outdoor side surface of the ridge, and the ridge-slip prevention member is formed of the ridge. The batten is fitted against Enhazure stop for clamping inlet grooves is characterized in that it is fixed.

[0010] In this case, a sheet-like cover member may be provided so as to extend further than the above-mentioned stripping edge stopper member. Further, specifically, in the engagement portion structure between the frame member and the ridge, at least one L-shaped engagement piece having an opening directed in the room direction is formed on the frame member, and the opening is directed to the ridge on the outdoor side. It is preferable that one or more L-shaped engaging pieces are formed, and that these two L-shaped pieces are engaged with each other by meshing with each other.

[0011] In the present invention, the ridge-separation preventing member extending from the glazing gasket and integrally provided is inserted into a sandwiching groove that opens outwardly along the panel surface formed between the frame member and the ridge. It is designed to fit. Therefore, since the force in the outdoor direction is always applied to the ridge, the ridge does not move even if it receives vibration or external force, and the engagement with the frame member is not released. In addition, since the sandwiching groove of the ridge separation preventing member is formed so as to open in an outward direction along the panel surface (an outward direction orthogonal to the prospective surface), the finding width can be reduced.

Further, even when the window unit is viewed from below, since the sheet-shaped ridge cover material is wrapped to the lower side to some extent, it is difficult to see the aluminum background, and in particular, the sheet ridge cover member is harder than the ridge stopper member. In the case where the sheet-shaped cover member is further provided so as to extend, even the back side of the panel boundary joint can be completely hidden, and the aesthetic appearance is improved.
