Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a curtain wall that is based on horizontal members and has face members attached within a frame formed by the horizontal members and the vertical members.

(Prior art) Conventionally, as a curtain wall based on horizontal members, a plurality of horizontal members are fixed at predetermined vertical intervals to a plurality of pillars fixed to the outside of a building frame.
A plurality of vertical members are connected between the horizontal members by fixing both ends of the vertical members to the horizontal members using L-shaped connecting fittings with a predetermined left and right interval, and these horizontal members and the vertical members are connected. A structure in which a face material made of glass is attached to each frame formed by the is known. However, with this conventional curtain wall, both ends of the vertical members are fixed to the horizontal members, so if an earthquake causes interstory displacement between building floor slabs, a large force is applied to the L-shaped connecting fittings, causing the vertical members to There were some inconveniences such as damage.

(Problems to be solved by the invention) The purpose of this invention is to prevent damage to the vertical members in the event of interstory displacement due to an earthquake.

(Means for solving the problem) In order to achieve the above purpose, the curtain wall of the present invention includes a plurality of horizontal members arranged horizontally with a predetermined vertical interval, and the plurality of cross members. In a structure in which a panel is attached to each frame formed by a plurality of vertical members arranged vertically with a predetermined left-right spacing between them, the horizontal members and vertical members are It has a structure in which it is fixed to each side through supporting materials. Embodiments of the present invention will be described below with reference to the drawings.

(Example) In Figs. 1 and 2, a plurality of supports 1 made of square iron pipes are vertically fixed at predetermined left and right intervals on the outside of the building frame F, and each of the supports 1... A plurality of horizontal members 2 made of aluminum shapes are fixed horizontally at a predetermined vertical interval at a ratio of three on each floor in this example, and these horizontal members are adjacent to each other above and below. Between the horizontal members 2, 2,..., a plurality of vertical members 3 made of aluminum shapes are vertically arranged at positions corresponding to the supporting members 1, and the vertical members 3 are connected to the horizontal members 2.
... are independently fixed to the supporting member 1..., and in this example, glass 4... is fitted as a face material in each rectangular frame formed by these horizontal members 2... and vertical members 3....

First, the means for fixing the supporting members 1 to the frame F is such that fasteners 8 made of angle materials are welded in advance to auxiliary plates 7 welded to each beam 6 of I-shaped steel supporting each floor slab 5. On the other hand, a bracket 9 made of a rectangular plate is welded to an inner position corresponding to each of the fasteners 8 of the support member 1, and the bracket 9 and the fastener 8 are connected to the bolts 10, 10 and the nut 1.
The structure is connected by 1 and 11.

The above-mentioned cross members 2... have face member fitting grooves 13 and 14 with a substantially rectangular C-shaped cross section at the upper and lower positions on the outer side of the hollow base 12 in the cross section as shown in the third figure, and the groove openings of one side 13 are located upward. , and the other 14 are arranged in series with the groove openings facing downward, and the hollow base 1
Groove portions 15 having a substantially rectangular C-shaped cross section on both upper and lower surfaces of 2,
16 are formed with the groove opening of one 15 facing upward and the groove opening of the other 16 facing downward, and two bolt head guide grooves 17, 17 having a rectangular C-shaped cross section are formed on the inner surface of the hollow base 12. are extended in the longitudinal direction of the cross members 2 and are connected with the grooves facing inward.

The means for fixing the cross members 2 to the supports 1 is as shown in FIG. The bolt 2 has a pair of angle fasteners 19, 19 at positions corresponding to the brackets 18 on the inner surface, and heads fitted into the bolt head guide grooves 17, 17 of the cross member 2.
0, 20 and nuts 21, 21, respectively, and the fasteners 19, 19 are secured to both ends of the bracket 18 by bolts 22, 22 and nuts 21, 21, respectively.
The structure is connected by 3 and 23.

The vertical members 3 have a substantially rectangular cross section C on the outer surface of the rectangular hollow base 24 as shown in the fourth figure in cross section.
The shaped face material fitting grooves 25 and 26 are arranged back to back with the groove opening of one side 25 facing left and the groove opening of the other 26 facing right, and the grooves 25 and 26 are arranged back to back to each other, and A bolt head guide groove 27 with a rectangular C-shaped cross section is formed in the center with the groove extending in the longitudinal direction of the vertical member 3 and with the groove mouth facing inward, and furthermore, a bolt head guide groove 27 with a rectangular C-shaped cross section is formed with the groove opening facing inward. The groove portions 28 and 29 are arranged in series.

The structure for fixing the vertical members 3 to the supporting members 1 is as follows. In this example, angle brackets 30, 30 are welded to the outer surface of each support member 1 at positions corresponding to the upper and lower ends of each vertical member 3, that is, at the upper and lower positions of each bracket 18, respectively. Angle fasteners 31, 31 are respectively fixed to the upper and lower ends of the inner surface of each vertical member 3 by bolts 32, 32 and nuts 33, 33 whose heads are inserted into the bolt head guide groove 27, respectively. As shown in the third figure, the lower end 37 of the vertical member 3 is slightly engaged in the upper groove 15 of the cross member 2, and the upper end 38 is slightly engaged in the lower groove 16, respectively.
In this state, fasteners 31, 31 of the vertical member 3 are attached to the brackets 30, 30 of the support member 1 with bolts 34,
34 and nuts 35, 35.

The above-mentioned glass 4... has face material fitting grooves 13, 14 of the horizontal members and face material fitting grooves 2 of the vertical members within a rectangular frame formed by the above-mentioned horizontal members 2... and vertical members 3...
5 and 26, respectively, and are supported by fitting the four peripheral parts into them. 36 is a sealing material around the four peripheries of the glass 4. 39... is a board attached to the waist wall to hide it from the outside, and the adjacent vertical members 3,
Both left and right end portions are supported by the groove portions 28, 29, . . . Reference numeral 40 denotes a connecting portion in the longitudinal direction of the cross member 2.

(Effects of the invention) According to the curtain wall of the present invention, the horizontal members and vertical members are not connected to each other and are fixed to the building side independently through supporting materials, so that the upper and lower floors of the building can be damaged by earthquakes. Even if interlayer displacement occurs between the slabs, it is possible to prevent the risk of damage to the vertical members as in the conventional method.
