Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall provided on an outer wall surface of a building and a method for constructing the curtain wall, and more particularly, to a structure for supporting a wall body and / or an attachment portion to a blind body. Or / and relates to a method of attachment to an eyeless body.

[0002]

2. Description of the Related Art In a curtain wall constructed by attaching a plurality of wall bodies made of glass panels, metal panels, tiles or stones to an outer wall surface of a building, a front view of FIG. 5 (A) and FIG. 5 (B). As shown in the side view of the building, the space between the horizontal members 30 and 31 of the upper and lower frames is long (e.g., reaching 8 to 9 m), as in the case of a building such as an entrance to a building.
In this case, since the cubic 1 made of the extruded aluminum alloy is also long, the cubical 1 alone cannot support the wind pressure load acting on the wall body 5.
As shown in the cross-sectional view of FIG. 1, a skeleton 2 is constructed in parallel with the cuboid 1 on the indoor side of the cuboid 1, and the cuboid 1 and the skeleton 2 are angled 3
The cuboid 1 is supported by the skeleton 2 by being fastened with 2, 33, bolts 34, and nuts 35.

In this case, the attachment work of the pedestal 1 to the skeleton 2 is performed while adjusting the pedestal 1 to the skeleton 2 because the skeleton 2 cannot be constructed with relatively high dimensional accuracy.
That is, several angles 32 are attached to one body 1 by adjusting the height of the body 2 with bolts 36 and nuts 37, and the angles 32 are attached to the body 1 in advance. 33 together, these angles 32,
Long holes 32a, 33a provided in 33 so as to intersect with each other
The structure has a structure in which the bolt 1 is inserted into the shaft 1, the position of the vertical 1 is adjusted, and the nut 35 is tightened to attach the vertical 1 to the frame 2.

In the figure, 3 is a blind which is connected to the upright 1 by a bracket 4, 5 is a wall which is supported by the blind 3 and the upright 1, and 6 and 7 are indoor side and outdoor side ridges, respectively. ,
Reference numeral 38 is a cover that covers the angles 32 and 33.

[0005]

However, according to this conventional structure, the angles 32 and 33 and the bolts 34 and nuts 35 that are the connecting means for them have a poor appearance, so that the cover made of an extruded aluminum alloy profile is used. It is necessary to cover these with 38, and there is a problem that the number of parts increases. In addition, since the number of parts is increased and labor is required for the mounting work correspondingly, it is necessary to adjust the combination positions of several pairs of angles 32 and 33 with respect to the cubic 1 respectively. There was a problem of taking time.

In view of the above problems, the present invention eliminates the need for a cover for a fitting, reduces the number of parts, and facilitates a vertical or / and blind installation work and a curtain wall and its construction. The purpose is to provide a method.

[0007]

In order to achieve the above object, the curtain wall of the present invention is constructed on the upright and / or unsightly supporting the wall body and on the inside of the upright and / or unsightly interior. Has a structure in which it is coupled with a frame by means of a metal fitting, and the metal fitting is composed of a first member fixed vertically or / and blindly and a second member screwed to the first member. It is characterized in that the screwing depth of the second member with respect to the first member is adjusted and the end portion of the second member is brought into contact with the skeleton body and welded.

Further, in the method for constructing a curtain wall of the present invention, the first member of the connecting metal fitting, which is made up of the first member and the second member screwed with each other, is made into a vertical or / or a wall supporting member.
And the eye is fixed to the eye, and the upright and / or the eye to which the connecting fitting is fixed is positioned so that the upright and / or the eye is supported on the frame through a jig. By rotating the two members and projecting them toward the body side, the second
It is characterized in that the member is brought into contact with the body and the second member is welded to the body, thereby connecting the body and the upright and / or unsightly via the fitting.

[0009]

In the curtain wall of the present invention, the metal fittings are attached to the vertical or / and unsightly, and the vertical or vertical
By positioning the and the eye-gaze, turning the second member of the fitting to contact the skeleton, and welding the second member to the skeleton, the upright and / or the eye-less is attached to the skeleton via the fitting. Therefore, if the upright or / and the seamless is positioned in advance at the position where it should be constructed, the adjustment can be completed simply by applying the second member of the coupling fitting, and the adjustment work can be simplified.

The first member 9 has a collar 9a, and a screw 11 is inserted into a hole provided in the collar 9a and the upright 1 to be screwed into a screw hole of a back plate 12 in the upright 1 to form the first member. 9 is fixed to the cubic 1. The second member 10 has a brim 10a for welding at its tip.

In FIG. 4, reference numerals 13 and 14 denote jigs for temporarily fixing the lower end and the upper end of the upright 1, respectively. These jigs 13 and 14 are U-bolts attached so as to hold the skeleton 2. 15 and 16 and L-shaped support plates 20 and 21, and the tips of the U bolts 15 and 16 are inserted into the horizontally long holes (not shown) of the vertical plate portions 20b and 21b of the support plates 20 and 21, respectively. The nuts 18 and 19 are tightened and fixed to the body 2. On the upper surface of the support plate 20 and the lower surface of the support plate 21, sleeves (position restriction members) 20a and 21a fitted in the inner space 1a of the upright 1 are fixed, respectively.

In order to attach the upright 1, as shown in FIGS. 1 and 2, in a factory, a fitting 8 composed of a first member 9 and a second member 10 which are screwed together and whose total length can be adjusted is provided. , The first member 9 is attached to the vertical 1 by fixing the first member 9 with the screws 11.
