TECHNICAL FIELD OF THE INVENTION
The present invention can minimize a horizontal member disposed along a horizontal joint between panels in a curtain wall structure in which panels such as glass are disposed adjacent to each other in a horizontal direction and an up-down direction, and in appearance, in a vertical stand The present invention relates to a curtain wall structure in which a panel surface is continuously visible in a vertical direction.
[0002]
[Prior art]
Conventionally, various structures have been proposed for curtain walls, which are the mainstream of wall structures in building construction. For example, the curtain wall CW shown in FIGS. 13 to 15 is provided with the cubicles 50, 50... At predetermined intervals in the horizontal direction, and seamlessly between the cubicles 50, 50 along the horizontal direction. And the peripheral edge of the panel is fitted and supported in the opening surrounded by the screens 50 and 50 and the blinds 51 and 51. On the other hand, in the curtain wall shown in FIG. 16, mounting holes 53 are formed at the four corners of the tempered glass G, and support bolts are inserted into the mounting holes 53 to strengthen the panel wall with the panel supporting device. A curtain wall (hereinafter, referred to as a frame type curtain wall) having a structure in which the panel supporting device is fixed to a structural support such as a pillar or a skeleton by connecting the glass to the glass. As shown in FIG. 17, for example, a support device for supporting the H-type (or X-type) panel support member 56 and a support member 57 connected to the panel support member 56, The panel support fitting 56 is provided with support bolts 55 at the distal end of each arm member. In addition, a seal is provided in the gap between the tempered glasses.
[0003]
In particular, the latter curtain wall is a relatively new type of curtain wall called the "DPG method", which does not have a frame to support the glass panel, which makes it possible to create a space with excellent lighting and a sense of openness. Has the advantage of
[0004]
[Problems to be solved by the invention]
However, in the case of the curtain wall according to the DPG method, the panel to be used is practically limited to tempered glass at present, even if the design is excellent. The cost is considerably higher than a normal curtain wall with a frame. In addition, when low-quality tempered glass is used, there is a fear of breakage or the like. Therefore, great care is required for quality control of the tempered glass, and high-precision drilling is required. Further, since the structure supports the tempered glass at the point, high accuracy is required for positioning accuracy and position adjustment, and there is a problem that the labor required for the construction is increased.
[0005]
Further issues in the future include problems with quality standards related to fire resistance and problems in ensuring safety in the unlikely event of damage, such as the development of shatterproof films that have better performance than those currently in use. Remains as a future topic.
[0006]
Therefore, a main problem of the present invention is to minimize the horizontal members arranged along the horizontal joints between the panels, and to make the panel surface seem to be continuously continuous in the vertical direction between the cubicles in appearance. Another object of the present invention is to provide a curtain wall structure that ensures a sense of transparency and openness.
[0007]
[Means for Solving the Problems]
The present invention for solving the above-mentioned problem is a curtain wall structure in which panels are arranged vertically and horizontally adjacent to each other.
The cubicles are arranged along the vertical direction at predetermined intervals in the horizontal direction, and are arranged along the horizontal direction at predetermined intervals in the vertical direction between these cubicles, and are suspended by the suspension rods or suspension wires. The horizontal supporting member supports the panel, and the panel supporting grooves formed along the vertical direction in the cubic portion support both side edges of the panel. It has a protruding piece, supports the panel's own weight by inserting this horizontal protruding piece between the grooves of the upper and lower panels, and has no finding portion covering the upper and lower edges of the panel on the outdoor side of the panel , and supports the panel's own weight. with the and is characterized in that a rotation preventing means for resisting rotation moment generated in said horizontal support member as the center of rotation of said suspending rod or hanging wire connecting portion
[0008]
In this case, a structure is preferably employed in which connection fittings are provided at upper and lower positions of the horizontal support member, and the suspension rod or the suspension wire is provided so as to connect the connection fittings to each other.
[0009]
As the rotation preventing means, for example, a pin member provided between the horizontal support member and the cubicle while being disposed on the indoor side of the hang member connection region at the cubic connection region and the hang rod or the hang member In addition to the wire, a pull-in rod or a pull-in wire provided at a position on the indoor side of the hanging rod or the position where the hanging wire is provided as a connection point may be used.
[0010]
In the case of the curtain wall structure of the present invention, the panel weight is supported by a suspending member such as a suspending rod or a suspending wire via the horizontal support member, while the wind pressure load on the panel is controlled by the panel fitting groove formed in the cubic portion. It is made to be supported by sharing by the support of both side edges. Therefore, the horizontal support member basically has a structure that does not support a wind pressure load, and does not require structural strength of the horizontal support member. In this case, a structure that does not have a finding portion that covers the upper and lower edges of the panel can be provided.
[0011]
That is, since the horizontal support is sufficient for a simple support structure that supports the panel weight by inserting a horizontal protrusion formed on the outdoor side of the horizontal support into the horizontal gap between the panels as described below, It is possible to provide a curtain wall surface in which the exposure and structural dimensions can be made extremely small as compared with conventional blinds and the like, so that the panel surface can be seen continuously in the vertical direction between the cubicles. It becomes possible.
[0012]
Further, as the panel, it is not necessary to use tempered glass as in the DPG method, and since a commonly used float glass is sufficient, it is possible to solve all the problems associated with the use of tempered glass as described above. become.

FIG. 1 is an external view of a curtain wall CW according to the present invention, FIG. 2 is an enlarged external view of a main part thereof, and FIG.
[0015]
As shown in FIGS. 1 and 2, when the panel wall is viewed from the outside, the curtain wall CW extends along the vertical joints of the glasses G, G,. .. (Hereinafter referred to as cubic lines) are visible, while at the horizontal joints the horizontal members are minimized and substantially formed between the glass G. This is a curtain wall in which only a few joints _MH are exposed, so that the panel surface can be seen vertically continuously between the cubic lines. In the present curtain wall CW, since the both sides of the glass G are continuously supported by the ridges 1 and 1, respectively, a float glass usually used in a curtain wall having a frame is used.
[0016]
As can be seen from the interior views shown in FIGS. 3 and 4, in the present curtain wall CW, vertically extending cubicles 1, 1... The horizontal joint members are provided with horizontal support members 2, 2,..., Which are suspended between the cubicles 1, 1, and supported by suspension rods 3, 3.

With the bent piece 11a (11b) and the protruding piece 10a (10b) as locking pieces, additional edges 13, 13 are provided on both sides of the extension plate portion 11, respectively, and are formed by the finding plate portion 12 and the additional edge 13. The glass G is supported by the glass fitting groove. That is, after attaching the leading bead 15 to the L-shaped bent pieces 12a and 12b formed on the back side of the finding plate portion 12, the backup material 14 is fitted into the back side with the glass G interposed therebetween. The glass G is continuously supported along both side edges by the general supporting method as described above. A sealing 16 is provided around the glass to prevent rainwater and the like from entering.
[0018]
On the other hand, as shown in FIG. 6 in the first embodiment, the horizontal support member 2 has a hollow hole portion 2A at one end side (indoor side) having a shape into which the rotation preventing pin 17 can be inserted, A hollow plate-shaped extrusion having a glass support portion 2B on the other end side (outside of the room) is used. The glass support portion 2B is formed in a horizontal T-shape in cross section. Specifically, the upper rear wall 2a supporting the lower edge rear surface of the upper glass G, and the upper rear edge of the lower glass G are formed in the lower rear portion. It is composed of a wall 2b and a horizontal protruding piece 2c inserted between the glass grooves to support the upper and lower end surfaces of the glass G and load the glass weight. Reference numeral 20 denotes a setting block for setting the glass G.
[0019]
As shown in FIG. 4, the horizontal support member 2 supports the vertical load, that is, the glass weight by the suspension rods 3 and 2 at two places between the partitions 1 and 1 in the illustrated example. At the connection portion to the vertical 1, the glass G is loaded on the front side of the horizontal support 2, and the rotational moment generated in the horizontal support 2 around the suspension point (the connection point of the suspension rod 3) as a rotation center. In order to resist, rotation is prevented by a rotation preventing pin 17 described later.
[0020]
First, as shown in FIG. 7, the hanging rods 3 supporting the weight of the glass G are placed on upper and lower positions of the horizontal support 2 relatively close to the outdoor side, respectively, so that the rotational moment is minimized. Connection fittings 4 and 4 are provided, and a suspension rod 3 is provided so as to connect these rod connection fittings 4 and 4 to each other. The reference numeral 3A provided on the suspension rod 3 is an adjustment mechanism for adjusting the entire length of the suspension rod 3, which is pressed by both sides just like a turnbuckle to rotate the central square cross section with a tool. This allows the total length to be adjusted.
[0021]
As shown in FIG. 8, for example, as shown in FIG. 8, an example of the top support structure of the hanging rod 3 which is structurally continuous in the vertical direction is the upper part of the A structure that connects points and is supported by diagonal rods 22 connecting the connection point and the cubic 1 or a structure that is not directly supported by the cubic 1 but is directly supported (not shown) on the frame. It can be.
[0022]
Further, as another example of the suspension structure using the suspension rods 3, for example, as shown in FIG. 9, the suspension rods 3 may be provided so as to be connected to the cubicles 1 for each horizontal support member 2. good.
[0023]
On the other hand, at the connection portion between the horizontal support member 2 and the ridge 1, as shown in FIG. 5, an insertion hole 10c is formed in advance on the ridge 1 side for the rotation preventing pin 17, and this insertion hole is formed. The parts are reinforced by reinforcing plates 19, 19, and when mounting the horizontal support member 2, the rotation preventing pins 17 are inserted into the hollow holes 2A and temporarily fixed by fixing screws 18 in a state where they are not projected outward. When the horizontal support member 2 is brought between the cubicles 1 and 1 and the hollow hole 2A is positioned at the insertion hole 10c forming portion, the fixing screw 18 is loosened, and the pin is pushed through the slot 2f (2e). The prevention pin 17 is pushed outward, and the tip is fitted into the fitting hole 10c. When the fixing screw 18 is fitted to a predetermined depth, the fixing screw 18 is screwed into the fixing screw 18, and its tip is cut into the outer surface of the rotation preventing pin 17 so that the position of the rotation preventing pin 17 is firmly fixed so as not to change. At the outdoor side of the end of the horizontal support 2, the angle members 20, 20 are fixed to the extension plate 11, and the horizontal support 2 is supported by the bracket portion.
By the way, in the first embodiment, the suspension rod 3 is used as the suspension member for suspending the horizontal support member 2, but a suspension wire may be used.
[0024]
[Second embodiment]
The second embodiment shown in FIGS. 10 to 12 shows a modification of the horizontal support member 2 and another example of the rotation prevention mechanism. Other structures are the same as those in the first embodiment, and thus the same reference numerals are given and the description is omitted.
[0025]
In the second embodiment, as shown in FIG. 12, a plate-shaped horizontal support 2 'is simply used in relation to a rotation preventing mechanism described later. Of the two rods 3 and 5 arranged side by side in the indoor and outdoor directions of the horizontal support 2 ′, the outdoor rod is a suspension rod 3 for suspending the horizontal support 2 ′ and located on the indoor side. The other rod 5 is a retractable rod on which a tensile force is applied on the lower side in order to resist the rotational moment. Of course, a retraction wire can be used instead of the retraction rod 5.
[0026]
When such an anti-rotation mechanism is employed, it is not necessary to use a hollow member as a horizontal support member, and a plate-shaped horizontal support member 2 'having a thickness that can withstand the weight of glass can be used.
[0027]
【The invention's effect】
As described in detail above, according to the present invention, the horizontal members arranged along the horizontal joints between the panels can be minimized, and the panel surface can be seen as if it were continuous in the vertical direction between the panels. For this reason, it is possible to secure a certain degree of transparency and openness even if it is inferior to the DPG method. In addition, since float glass that is commonly used as a panel can be used, all problems associated with the use of tempered glass in the DPG method can be solved, and the cost is comparable to that of the conventional frame type curtain wall. It can be.
