[Industrial application fields]
The present invention relates to a panel material support structure for a curtain wall construction method in which a plate-like member such as glass is continuously attached in a vertical direction (called a corrugated window) using horizontal indirection and vertical orientation. About.
[0002]
[Prior art]
FIG. 7 is an explanatory view showing a state of transmission of the weight of the conventional curtain wall, and FIG. 6 is a cross-sectional view of the main part of the panel material support structure in the curtain wall structure. 1j, 1h and 1i are glass plates (plate-like members), 2, 2c and 2d are seamless, 3c and 3d are vertical, 4Q, 4r, 4s and 4t are setting blocks under the plate-like member, and 7 is a sealant. Yes, glass plates 1j, 1h, 1i are stepped into openings surrounded by vertical and invisible lines.
[0003]
As shown in FIG. 7, a plate-like member 1 (1h, 1i, 1j, etc.) made of glass, etc., has a horizontal invisible 2 (2c, 2d, etc.) and a vertical orientation 3 (3c, 3d, etc.). In the panel member support structure for the curtain wall construction method attached using the plate member 1, the weight of the plate member 1 is when the lateral width of the plate member 1 is L at the lower side of the plate member 1 (1h, 1j, etc.). , And transmitted through the setting blocks 4 (4Q, 4r, 4s, 4t, etc.) installed at two points of about 1/4 (L / 4) of the lateral width from both ends to the invisible 2 (2c, 2d, etc.) below. The Therefore, the blank 2 must have rigidity to support the weight of the upper plate-like member 1 and the weight of the blank 2 itself. For this reason, as shown in FIGS. 5 and 6, the found height M is increased. Conceptually, the weight is transmitted as indicated by arrows A and B.
[0004]
In addition, when a curtain wall construction building is subjected to an earthquake, a plate-like member whose width is larger than its height is higher than the horizontal component of the vibration of the building caused by deformation of the ground (called the sway amount). The rotational vibration component (called rocking amount) of the building caused by the rotation is large, so that a sufficient interval 15 between the plate-like member and the upper portion thereof is provided so that the plate-like member does not collide with the upper portion. This is necessary, and this is one of the causes for increasing the apparent height M. This means that M becomes large because M3 becomes large.
[0005]
[Problems to be solved by the invention]
In recent years, with the widespread use of perforated tempered glass facade construction methods (dot point construction methods), construction methods that emphasize the transparency of glass itself have been actively developed in recent years. Therefore, it is desired to develop a panel material support structure for a curtain wall construction method in which the invisibility and the vertical supporting the glass are made as small as possible with a small cross section.
[0006]
In order to alleviate the drawback that the cross-section of the member that supports the plate-like member, which the panel member support structure for the conventional curtain wall construction method, has a large design, The aim is to provide a curtain wall with a small design and high design.
[0007]
[Means for Solving the Problems]
In the present invention, a plurality of verticals are fixed to a building frame in the vertical direction, and a plurality of blanks are installed in the horizontal direction between the squares, and a plate-like opening is surrounded by the verticals and the blanks. In the panel material support structure for the curtain wall construction method formed by stepping using a member,
At least two left and right lower setting blocks are inserted between the first plate and the first plate member disposed immediately above the first plate ,
The total weight of the weight transmitted from the first plate-like member and the first weightless weight,
Both If you transferred to the mullions that the first of the transom through the first of the transom own Erection fixed,
For the second plate-like member disposed directly below the first transom, for curtain wall construction method characterized by transmitting through the inserted upper setting block immediately below the first transom A panel material support structure is provided .
[0008]
By configuring in this way, the weight of the plate-like member and the mute itself is also transmitted to the plate-like member arranged immediately below the mute, so that the strength of the mute may be lowered, Can be made smaller in height (N, P).
[0009]
Further, when the earthquake occurs, the plate-like member 1 is hardly rocked, and a mechanism for causing a sway is formed. In other words, the plate-like member 1 has a lower setting block 4 and an upper setting block 5 at the time of the earthquake. 4, the vertical movement hardly occurs, and the in-plane deformation is absorbed by sliding in the horizontal direction between the plate-like member 1 and the invisible part 2 above the plate member 1. ) And (b), N3 and P3 can be reduced, and the invisible height (N, P) can be further reduced.
[0010]
The present invention further includes at least two left and right lower setting blocks inserted between the first blank and the first plate-shaped member, so that the first left and right lower setting blocks are the first. The weight of the total amount of the weight transmitted from the first plate-like member disposed immediately above the first eyeless member and the first weightless weight is both when you transfer the mullions are bridged secure the transom, the lateral width of the main surface of the first plate-like member when the L, 2 pieces of the lower setting blocks mainly of the first plate-like member The panel material support structure for a curtain wall construction method according to claim 1, wherein the panel material support structure is inserted at positions closer to L / 20 from the left and right ends of the surface.
[0011]
By configuring in this way, the bending moment due to the weight from the plate-like member transmitted through the lower setting block becomes smaller, so the strength of the eyeless may be lowered, and the eyesight can be found. The height (N, P) can be made smaller.
[0012]
More preferably, the value is L / 80 to L / 100 instead of L / 20. More preferably, the distance z from the end of the plate member to the end of the lower setting block is about 20 mm. The lower setting block is not limited to two, one of a total of three may be arranged in two and the center arranged at both ends of the.
[0013]
Further, in a preferred embodiment of the present invention, the upper part setting block is arranged substantially at the center of the main surface of the second plate-like member. The upper setting block is not limited to one, and may be two. When the upper setting block 5 is a block made of chloroprene rubber whose upper and lower surfaces are covered with a Teflon (registered trademark) sheet, a block made of Teflon (registered trademark) , or a block made of high-strength polycarbonate, the friction coefficient is increased. Since it can be made smaller, it is preferable when an earthquake occurs.
[0014]
[Action]
According to the above configuration, the blindness does not have to bear the weight of the weightlessness and the weight of the plate-like member, and it is sufficient to have a cross section that can withstand the wind pressure in the horizontal direction. A curtain wall that can be significantly reduced in size and has high design properties can be provided.
[0015]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
FIG. 3 is an explanatory view showing a state of transmission of weight in the curtain wall structure of the present invention, and FIGS. 1 and 2 are cross-sectional views of main parts of the panel material support structure in the curtain wall structure of the present invention. . 1 (1h, 1i, 1) is a plate-like member such as a glass plate, 2 (2a, 2b) is plain, 3 (3a, 3b) is vertical, 4 (4a, 4b, 4d, 4e) is plate-like member lower Oasys Tsu computing block, 5 plate-shaped member on Oasys Tsu computing block, 6 ledge, 7 is a sealant.
[0017]
Conceptually, the weight of the mesh 2 is transmitted to the lower plate-like member 1 through the upper setting block 5 installed at the center of the width of the lower side of the mesh 2. The weight of the lower plate-like member 1 is added to the weight of the blank 2 and transmitted to both ends of the lower blank 2 through the lower setting blocks 4 installed on both ends of the lower side of the plate-like member 1. It is transmitted to the vertical 3. That is, conceptually, the weight is transmitted as shown by arrows C, D, E, F, G, and H. For this reason, the invisible 2 need not take up the weight of the invisible 2 and the weight of the plate-like member 1 and only needs to have a cross section that can withstand wind pressure in the horizontal direction. Therefore, a curtain wall with high design can be provided.
[0018]
FIG. 2 is an example in which an invisible cross-sectional shape is different from that in FIG. 1, but the way in which the weight of each member is transmitted is almost the same as in the configuration in FIG. 1.
[0019]
Moreover, in this invention, when it receives an earthquake, it is set as the mechanism which raise | generates a sway, hardly causing rocking to the plate-shaped member 1. FIG. That is, since the plate-like member 1 is sandwiched between the lower setting block 4 and the upper setting block 5 at the time of the earthquake, the vertical movement hardly occurs, and the plate-like member 1 and the upper portion 2 of the upper portion thereof are not affected. In-plane deformation is absorbed by sliding in the horizontal direction. For this reason, the upper setting block 5 between the upper side of the plate-like member 1 and the upper part 2 of the plate-like member 1 is configured such that a Teflon (registered trademark) sheet is sandwiched between the upper and lower surfaces of a normal chloroprene rubber setting block. It is preferable to reduce the friction coefficient by using a Teflon (registered trademark) block, a high-strength polycarbonate block, or the like.
[0020]
Further, the lower setting block 4 between the lower side of the plate-like member 1 and the lower part 2 is preferably chloroprene rubber having a hardness of 90 degrees or more, which is the same material as that of a commonly used setting block.
