2. Description of the Related Art In a building such as a building, an outer wall is formed by a curtain wall which is a non-bearing wall. For example, when such a curtain wall is used to form a wall at the corner of a building, a blind material bent in accordance with the angle of the corner is prepared, and the end side of the blind material is erected. Was supported by. Therefore, there is no erection or the like supporting the blind material at the position corresponding to the corner of the protruding corner, and when the glass plate or the like is fitted, the corner side of the blind material due to its weight is reduced. The problem of bending occurs.

In order to solve such a problem, conventionally, a bent blind material is indirectly suspended by a suspension bolt via a bracket fixed to a corner thereof, or the blind material is directly suspended by a suspension bolt. In many cases, the upper ends of the connecting rods constituting the suspension bolts are fixed to the building frame, thereby supporting the blind material without bending. This problem is the same at the corner.

[0004]

However, when a blind material is hung indirectly by a suspension bolt, a dedicated bracket corresponding to a bending angle of the blind material is provided at a mounting portion between the connecting rod and the blind material. In addition, even when directly hanging, there is a problem in workability, such as the use of special nuts and the like, which requires expensive parts and requires the use of special tools. For this reason, there is a need for a curtain wall that employs suspension bolts that can be easily formed with seamless materials by using suspension bolts with less expensive components.

An object of the present invention is to provide a curtain wall which can reduce costs and improve workability by using general-purpose components as hanging bolts .

SUMMARY OF THE INVENTION A curtain war according to the present invention is provided.
The eyepiece has a through hole that forms a corner portion and has a through hole that penetrates vertically, a connecting rod having an upper end fixed and a lower end inserted through the through hole of the eyeless material, and a lower end side of the connecting rod. And a suspension bolt composed of a pair of hexagon nuts screwed up and down with an interval between them, wherein the blind material is clamped between the pair of nuts of the suspension bolt.

In the present invention, when the connecting rod of the suspension bolt is attached to the blank, a normal hexagon nut which is easily available as a general-purpose part is used.
This eliminates the need for special parts as in the prior art, thereby reducing costs. In addition, the work of tightening these hexagon nuts and the like is easily performed by a general-purpose tool, so that workability is also improved.

[0008] In the curtain wall of the present invention, the lower hexagonal nut of the pair of hex nuts that constitutes the hanger bolts and high nut, the lower end of the upper side or et communicating <br/> rod in the high nut The upper end of another connecting rod may be screwed from below. In such a case, since the seamless material is suspended over a plurality of upper and lower stages, it is possible to cope with a corner portion of a large curtain wall formed by a plurality of upper and lower curtain wall units and the like.

In the curtain wall of the present invention,
The connecting rod of the suspension bolt may be a round bar, and a tool grip having a flat surface may be provided at an intermediate position in the vertical direction of the round bar. In such a case, it is possible to further reduce the cost by using a generally available round bar as the connecting rod, and even if such a round bar is used, it may be in the middle of the vertical direction. In order to provide a tool grip having a flat surface at a position, for example, a round bar is securely held by using a wrench or the like, and operations such as screwing and fixing of a connecting rod are easily performed. Become like

A hollow portion 18 having upper and lower horizontal surfaces 18A and 18B is continuously provided along the expected direction on the indoor side of the blind material 12 as described above. In the hollow part 18,
As shown in FIG. 3, through holes 18C and 18D penetrating the horizontal surfaces 18A and 18B are formed.

In FIG. 3, through holes 18C and 18D
Is a connecting rod 1 made of a round bar made of stainless steel or the like from above.
9 is inserted. A male screw portion 19A is engraved on the lower end side of the connecting rod 19, and a hexagonal nut 21 is screwed into the male screw portion 19A in advance before the connecting rod 19 is inserted. Packing material 23 is inserted. After the insertion, the male screw portion 19A protruding from the lower through-hole 18D has a similar packing material 2 attached thereto.
3. A round washer 22 is inserted, and a high nut 24, which is a hexagonal nut having a large vertical dimension, is screwed.

That is, the blank 12 is sandwiched between the upper and lower hexagonal nuts 21 and the high nut 24, and the height of the blank 12 is adjusted by shifting the positions of the nuts 21 and 24. I can do it. In the present embodiment, the connecting rod 19, the nuts 21 and 24, the washer 22,
The packing material 23 forms a set of suspension bolts 25 according to the present invention. In the suspension bolt 25, the nuts 21, 24, the washer 22, and the packing material 23 are generally standard products that are generally commercially available, and are easily available general-purpose components.

The female screw portion 24A of the high nut 24 is screwed not only with the upper connecting rod 19 but also with the upper end of the connecting rod 19 which constitutes another hanging bolt 25 on the lower side. The lower portion of the rod 19 has the same structure as that described above, and is attached to the blank 12. That is, reference numeral 19 in FIG.
B is a male screw portion provided on the upper end side of the lower connecting rod 19.

On the other hand, though not shown, the connecting rod for suspending the blind material at the top of the curtain wall 10 has its upper part fixed to a building frame such as a ceiling slab through an appropriate fixing means. Through the connecting rod and the lower connecting rod connected to the connecting rod, all the blind material in the vertical direction is reliably suspended from the skeleton.

As shown in FIG. 3, both sides of a pair of parallel flat surfaces 26A, which are tool gripping means, are provided near the nuts 21 and 24 in the vertical direction of each connecting rod 19, as shown in FIG. A notch 26 is provided. The cutouts 26 on both sides are obtained by, for example, cutting or pressing.

In this embodiment, an L-shaped seamless material 12 is formed in advance by welding of an extruded aluminum material 11 at a factory or the like, and then this seamless material 12 is connected to another linear seamless material. The material 12A (FIG. 1), the cubic 13 and the face material 14 are transported to the construction site. At the construction site, the construction is performed from the uppermost blind material 12 using the suspension bolts 25, and the construction is sequentially performed toward the lower stage.

In this operation, first, the upper end of the connecting rod 19 constituting the suspension bolt 25 is screwed to a fixing means provided on a building frame or an upper high nut 24. At this time, by screwing the notches 26 on both sides provided on the connecting rod 19 with a spanner or the like, the connecting rod 19 can be easily screwed.

Next, a hexagon nut 21 is screwed in from the lower end of the connecting rod 19, and a round washer 22 and a packing material 23 are inserted therethrough.
Thereafter, the connecting rod 19 is inserted into the through holes 18C and 18D from above. Then, a similar packing material 23 and a round washer 22 are inserted into portions protruding from the through holes 18D of the connecting rod 19,
The high nut 24 is screwed, and the high nut 24 is tightened while gripping and fixing the connecting rod 19 with a spanner. Thus, the construction of one set of the suspension bolts 25 is completed. Lower bolt 2
The same procedure is applied to No. 5.

According to this embodiment, the following effects can be obtained. That is, in the hanging bolt 25, when the connecting rod 19 is attached to the blind material 12, the general hexagon nut 21 and the high nut 24, which are general-purpose components, are used. Therefore, cost can be reduced. Further, such a tightening operation of the nuts 21 and 24 can be easily performed by a general-purpose tool such as a spanner or a hexagon wrench, and the workability can be improved.

Since a generally available round bar is used as the connecting rod 19, the cost can be further reduced.

Further, since a high nut 24 having a large vertical dimension is provided at the lower end of the connecting rod 19, this high nut 2
By further screwing another connecting rod 19 to the lower part 4 from above, it is possible to suspend the seamless material 12 over a plurality of upper and lower stages,
Even when the curtain wall 10 is made to be a large one formed by a plurality of upper and lower surface materials 14 or curtain wall units, it is possible to reliably cope with the protruding corner portion A.

Further, since the notch 26 having both sides having a flat surface 26A is provided at an intermediate position in the vertical direction of the connecting rod 19, the connecting rod 19 is locked with a notch 26 such as a spanner or a wrench. Even if a round bar is used as 19, the connecting rod 1
9 can be securely held, and operations such as screwing and fixing of the connecting rod 19 can be easily performed.

Further, each of the nuts 21 and 24 and the blank 12
Since the packing material 23 is interposed between them, the intrusion of dew condensation water and the like into the seamless material 12 from the through holes 18C and 18D can be more reliably prevented. And packing material 23
There is also an effect that the nuts 21 and 24 can be made harder to be loosened by interposing.

Further, since each component of the suspension bolt 25 is accommodated within the prospect of the blind material 12, a table board, a frame, a curtain box, and the like interfere with the suspension bolt 25 on the indoor side of the blind material 12. You can put it without letting it go. And since the blind material 12 is directly hung by the suspension bolt 25, a special bracket according to the bending angle of the blind material 12 which is used when hanging indirectly can be eliminated, The suspension bolts 25 can be used for other protruding corners A having different angles.

The present invention is not limited to the above-described embodiment, but can be applied to a corner. In the above-described embodiment, the nuts 21 and 24 and the blank 1
Although the packing material 23 is interposed between the two, the packing material 23 is not an essential member of the present invention and can be omitted. However, the effect described above may be obtained by interposing the packing material 23.

In the above embodiment, the notches 26 provided on the connecting rod 19 are formed by a pair of flat surfaces 26 parallel to each other.
Although A is provided, the tool holding means according to the present invention may be formed in a square cross section, a regular hexagonal cross section, or the like. The connecting rod 19 is not limited to a round bar, but may be a bar having a square cross section or a regular hexagonal cross section.
In such a case, the cost is high as a member,
On the other hand, there is an advantage that it is not necessary to separately provide the tool gripping means as described above.

Further, the blind material 1 provided particularly at the lowermost part
As a suspension bolt 25 for suspending the
Since there is no connecting rod screwed from below, a hexagonal nut 21 may be used instead of the high nut 24.

[0032]

As described above, according to the present invention,
Since the connecting rods constituting the suspension bolts are attached to the blank using hexagon nuts, which are general-purpose members, the cost can be reduced and the installation work can be simplified by using general-purpose tools. There is.
