Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall arranged on the outer wall side of a building.

[0002]

2. Description of the Related Art The above curtain wall is widely used for new construction, for example, for covering the exterior wall surface of a concrete exposed structure, and for refurbishment for covering the obsolete or damaged exterior wall surface of an existing building. A base structure is provided on the outer wall side of a building, and exterior panels are stretched on the base structure in a vertical and horizontal direction via panel holding means.

Among these, for example, a curtain wall intended for renovation of an existing building is proposed by Japanese Patent Publication No. 4-42513. Here, a base is fixed to the old outer wall, and a vertical member that also serves as the centering of the exterior panel (new outer wall) is fixed by extending it over the entire length of the old outer wall. A horizontal member that extends in the horizontal direction is fixed to the member to form a base structure for fixing the panel with the above configuration, and an exterior panel and a new window frame are attached to the horizontal member of the base structure.

In such a construction, if the vertical member is fixed in a predetermined centering state, the horizontal member is fixed to the vertical member after the vertical member and the exterior panel including the new window frame is aligned to the horizontal member. Fixing is easily achieved.

[0005]

However, this is not because the manufacturing error of the horizontal member and the exterior panel is taken into consideration. No matter how the basic vertical member is centered and fixed, the horizontal member and the outer member are not fixed. Since there are two manufacturing errors in the panel for use,
It was not possible to fix the exterior panel in a predetermined centering state by simply fixing the horizontal material and the exterior panel to the vertical material. In particular, in a glass panel type curtain wall that uses reflective glass, the scenery reflected on the reflective glass is greatly distorted, and in the end, many panel fine adjustments are required, which is very troublesome.

It is an object of the present invention to provide a curtain wall in which the exterior panel can be fixed with high precision by the rational improvement of the underlayer structure with the same number of working steps as the conventional one.

[0007]

In order to achieve the above object, the curtain wall according to the present invention has horizontal members arranged on the outer wall side of a building at a predetermined interval in the vertical direction, and at the same time the upper and lower horizontal walls. A structural feature is that a vertical member for tensioning the panel is provided in a predetermined centering state over the material, and an exterior panel is stretched continuously on the vertical member in the vertical direction and the horizontal direction.

[0008]

According to the above characteristic structure, the vertical member is provided on the outer wall side of the building in a predetermined centering state through the horizontal member, and the exterior panel is attached to the vertical member, whereby the exterior panel One of the factors that lowers the mounting accuracy, that is, the cross member deviates from the centering configuration system of the exterior panel.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a layout form of a new or refurbished curtain wall arranged so as to cover the outer wall 1 of a building, and FIGS. 2 and 3 show sectional layout views of the curtain wall.

In these drawings, reference numeral 2 in the drawings denotes a curtain wall base structure, and as shown in FIG. 4, anchor bolts 3 and nuts 4 are provided at predetermined intervals L in the vertical and horizontal directions. A bracket 5 having a V-shape is provided on the outer wall 1 of the skeleton, and a C-shaped cross member 7 having a downward opening is attached to the bracket 5 adjacent to each other in the left-right direction via a bolt / nut 6 for temporary fixing and by welding. Further, a C-shaped vertical member 10 having an outward opening is attached to a bracket 8 held in the downward opening of the horizontal member 7 by advancing vertically adjacent brackets 8 which are adjacent to each other. .

The bolt insertion holes a and b of the bracket 5 are oblong holes, respectively, so that the vertical position of the bracket 5 can be adjusted and the margin of the cross member 7 with respect to the outer wall 1 can be adjusted. It is also possible to adjust the longitudinal position of the cross member 7 relative to the cross member 7 and the holding position of the bracket 8 relative to the cross member 7.

Further, the holes c and d for bolt connection between the bracket 8 and the vertical member 10 held by the horizontal member 7 are larger than the bolt diameter, and the vertical member 10 is in a predetermined centered state (for example, The vertical member 10 is constructed so that it can be temporarily adjusted by a so-called vertical structure such as a downswing and a margin for the outer wall 1), and the vertical member 10 is welded to the bracket 8 in a predetermined centering state. .

Reference numeral 11 denotes an exterior panel which constitutes a curtain wall, and is formed by providing a reinforcing frame 13 on the peripheral portion of a plate-like panel member 12 each made of, for example, an aluminum material, and connected in a vertical direction and a horizontal direction and The upper side of each panel 11 is attached to the vertical member 10 of the base structure 2 via the panel holding means 14 so as to cover the outer wall 1.

More specifically, as shown in FIGS. 5 and 6, the panel holding means 14 is provided on the lower side of the abutted member 15 that abuts the outer surface of the flange portion e on the outward opening side of the vertical member 10. In addition, the upward and downward locking members f, f are integrally connected to each other, and the bolt 16 inserted into the left and right elongated hole h formed in the abutted member 15 and the vertical member 10. With the nut member 17 locked to the inner surface of the flange portion e, it is configured to be attached to the vertical member 10 in a position adjustable in the vertical and horizontal directions.

Position fixing means 18 for preventing the vertical displacement of the panel holding means 14 is provided in the base structure 2. This position fixing means 18 is
An L-shaped member 19 that engages with the concave groove i formed in the abutted member 15 is fixed to the vertical member 10 via a fixing bolt 20 and, if necessary, by welding.

On the other hand, the reinforcing frame 13 constituting the exterior panel 11 has the panel holding means 14 on the upper frame 13a thereof.
Has a groove member 21 for engaging the locking members f, f of
The panel holding means 14 is engaged in advance on both sides of the groove member 21 in the longitudinal direction, and is fixedly held by the stop pin 22. Further, the locking member 23 facing upward is continuously provided integrally with the groove member 21, and the elongated hole h of the panel holding means 14 is positioned higher than the upper edge of the locking member 23. Has been established.

On the lower frame 13b of the reinforcing frame 13, the locking member 23 of the lower panel 11 is attached in a predetermined panel mounting state.
The plate part 2 for draining, which faces the outer surface side of the
4 are provided in a hanging manner, and further, a groove portion 25 into which a bolt head is slidably engaged is also provided. The locking member 23 is engaged with the draining plate 24, in other words, the locking member 23 is locked to the inner surface side to the outside of the panel 11. A locking member 26 for restricting the tilt is attached by a bolt / nut 27 engaged with the groove 25.

Reference numeral 28 is a water-bending member made of, for example, an aluminum material,
It is elastically fitted and held to one side frame 13c of the panel 11 and the lower frame 13b of each panel 11 which are adjacent to each other in the left-right direction.

The left and right side frames 13c of the reinforcing frame 13
Is the same as the lower frame 13b having no locking member 26,
Moreover, these frames 13b and 13c have the same cross-sectional shape as the upper frame 13a in which the upper side of the groove member 21 is cut off. Further, the locking member 26 on the lower side of the panel is provided so as to be positioned in the central portion between the panel holding means 14 on both sides of the upper panel.

The exterior panel 11 having the above structure is installed in the following manner. That is, in the previous step, the lower locking member 26 of the upper panel 11 which should be directly next is locked to the upper locking member 23 of the panel 11 attached to the vertical member 10 of the base structure 2, The upper panel 11 is held in the lower panel 11 in a state where the outward tilt of the upper panel 11 is restricted.

Then, the upper side of the upper panel 11 is attached to the vertical member 10 of the base structure 2 through the panel holding means 14 which is fixedly held on the upper panel 11 in advance. Since 11 is fixedly held, the curtain wall can be stretched by installing the exterior panel 11 in the up-down direction and the left-right direction.

At the time of installing the exterior panel 11, a horizontal member 7 is provided on the outer wall 1 of the building through the bracket 5,
Since the vertical member 10 is provided on the horizontal member 7 in a predetermined centering state, and the exterior panel 11 is attached to the vertical member 10, the exterior panel 1 for the base structure 2 is provided.
The mounting accuracy of 1 becomes high.

That is, by finally obtaining the vertical member 10 to which the exterior panel 11 is to be attached and providing the vertical member 10 on the horizontal member 7 in a predetermined centered state, the mounting position of the horizontal member 7 is not finely adjusted. Roughly, even if the horizontal member 7 and the exterior panel 11 are manufactured in error, the horizontal member 7 mounting error and manufacturing error do not affect the centering and fixing of the external panel 11, That is, the horizontal member 7, which has been a factor of lowering the mounting accuracy in the configuration, is provided between the outer wall 1 side and the vertical member 10 which is centered and fixed, thereby lowering the mounting accuracy of the exterior panel 11. By eliminating one of the above, it is possible to attach the exterior panel 11 with high accuracy while the base structure 2 is attached in the same number of work steps as the conventional one and the horizontal member 7 is attached roughly. Of.

In the above embodiment, the panel holding means 1
Although the exterior panel 11 is provided on the vertical member 10 via the connector 4, it is needless to say that the exterior panel 11 can be directly attached to the vertical member 10.

[0025]

As described above, according to the present invention, a vertical material is sought to be attached to the exterior panel, and the rational base structure is provided to provide the horizontal material in a predetermined centering state.
It has a structural feature in that the horizontal member, which has been a factor of lowering the mounting accuracy in the structure, is removed from the structure system for directly centering and fixing the exterior panel. Also, even if the manufacturing error of the exterior panel is taken into consideration, and even if the horizontal member is roughly mounted, the factor that reduces the panel mounting accuracy due to the horizontal member is reduced by one. However, the mounting of the exterior panel has been achieved with high accuracy. In particular, it is remarkable to reduce the number of panel fine adjustment steps in a curtain wall using a reflective glass panel.
