Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for an inclined curtain wall which constitutes a wall surface of a building.

[0002]

2. Description of the Related Art A curtain wall is known as a constituent of a wall surface of a building. This curtain wall is a rectangular frame part which is formed by horizontally crossing a blind space between vertical sides connected to a building frame by fasteners. There is known a vertical curtain wall in which a panel material such as glass or shoji is attached to the part.

Since this curtain wall is normally connected to the slab, that is, to the building frame forming each floor, with the upright standing vertically, each upright is connected to the slab on each floor at the longitudinal intermediate position, and the supporting strength of the curtain wall is increased. Therefore, the curtain wall does not bend in the out-of-plane direction due to strong wind and rain.

However, as shown in Japanese Utility Model Laid-Open No. 3-73318, in the case of a curtain wall in which a plurality of floors are formed with a crotchhole, the upright of the upright of the upright is the upright of the upright. The lower part and the lower part are connected to the building frame that is separated by multiple floors to form an inclined curtain wall, which inevitably lengthens the uprightness, weakens the supporting strength of the curtain wall, and the inward and outward directions due to the weight of the curtain wall and strong wind and rain. May be curved.

For this reason, in the inclined curtain wall disclosed in Japanese Utility Model Laid-Open No. 3-73318, a space truss is attached to the building frame in parallel with the curtain wall, and the beam and the cube forming the space truss are connected to each other. The support strength of the curtain wall is strengthened.

[0006]

However, if the supporting strength of the curtain wall is reinforced by the space truss, the space truss is visually recognized from the outside of the room and the appearance is unsatisfactory.

Therefore, an object of the present invention is to provide a reinforcing structure for an inclined curtain wall which can solve the above-mentioned problems.

[0008]

[Means for Solving the Problems] In a sloped curtain wall in which an upper portion and a lower portion of a cuboid 20 constituting a curtain wall are respectively connected to a building frame side and inclined with respect to a vertical direction, a support member 30 is provided on the cuboid 20. Is provided toward the outdoor side, and both ends of the reinforcing cord 32 inserted into the support member 30 are connected to the upper side and the lower side of the upright 20, respectively,
The hanging rope 33 is connected to the longitudinal middle portion of the upright 20 and the hanging rope 33 is connected to the side of the building body to make the upright 20.
Reinforced structure of the slanted curtain wall that suspends and supports.

[0009]

[Operation] Since the hanging ropes 33 prevent the vertical 20 from bending toward the inside, and the reinforcing ropes 32 prevent the vertical 20 from bending toward the outside, the inclined curtain wall is It is possible to prevent the positive curtain from bending to the inside of the room, and to prevent the inclined curtain wall from bending to the outside due to the negative pressure. Further, since the thin reinforcing cords 32 and the suspension cords 33 are only visible from the outside of the room, the appearance is good.

[0010]

[Example] As shown in Fig. 1 and Fig. 2, horizontal ribs 2 made of H-shaped steel are longitudinally spaced between longitudinal bones 1 made of a plurality of steel materials which are erected at intervals in the in-plane direction. And a plurality of them are laterally connected to form a lattice-shaped front frame structure 3, and each longitudinal bone 1 thereof
The horizontal members 4 made of steel are connected to each other at an interval in the vertical direction to form a building frame, and floor slabs 5 are provided on each of the horizontal members 4, and the first floor portion 6, the second floor portion 7, 3rd floor part 8,
Each floor of the fourth floor portion 9, the fifth floor portion 10, and the sixth floor portion 11 is constructed, and a curtain wall 12 is attached to each floor to construct an outer wall of the building, and a horizontal frame 2 of the foundation portion 13 and the third floor portion 8
An inclined curtain wall 14 is attached obliquely to the vertical over the outdoor side of the above, and a catwalk 15 is attached to the outdoor side of each of the third and higher floors so as to project from the curtain wall 12 to the outdoor side.

Next, the mounting structure of the inclined curtain wall 14 will be described. As shown in FIGS. 3 and 4, glass supports 21 are attached to the inner surfaces of the plurality of uprights 20, respectively.
This glass support tool 21 is one in which four glass support parts 23 are provided in a cubic shape on a vertical mounting part 22, and one glass support part 2 of the four glass support tools 21 that are adjacent in the vertical and horizontal directions.
One piece of glass 24 is attached to each of the three pieces to form a curtain wall. In addition, two adjacent cubes
It is also possible to lay a blind eye between 0s and attach glass to the frame to form a curtain wall.

The upper portion of the upright 20 is bolted to a bracket 25 fixed to the horizontal frame 2 on the third floor, and the lower portion of the upright 20 is fixed to the base 13 as shown in FIG.
The lowermost edge of the glass 24 is bolted to the base 13 and is fitted into the upward recess 28a of the frame member 28 fixed to the base 13 with the fastener 27 and sealed with the seal material 29.

A plurality of supporting members 30 are fixed to the middle portion of the outer surface of the upright 20 in the longitudinal direction at intervals in the longitudinal direction, and the tips of the respective supporting members 30 face in the upright longitudinal direction. Through holes 31 are formed, and reinforcing ropes 3 such as small diameter steel rods and wires are formed in the through holes 31.
2 is inserted, and one end of the reinforcing cord 32 is fixed to the lower end of the outdoor surface of the upright 1, and the reinforcing cord 32
The other end of is fixed to the upper end of the outdoor surface of the cubic 1.

One end of a suspension cord 33 such as a small-diameter steel rod or wire is fixed to the outdoor surface of the vertical portion of the vertical portion 20 in the longitudinal direction. The other end of the suspension cord 33 is attached to the bracket 25. It is fixed to the tip of the supporting cross member 34.

The supporting cross member 34 is a catwalk 15.
The supporting cross members 34 are for supporting the slings 3.
As shown in FIG. 1 and FIG. 2, since it is suspended and reinforced by an auxiliary frame 36 made of steel that is fixed to the uppermost portion of the vertical frame 1, the connection strength of the supporting horizontal member 34 to the horizontal frame 2 is shown in FIG. Although it may be weak, it is necessary to firmly connect the supporting cross member 34 to the lateral bone 2 when there is no upper hanging rope 35.

The reinforcing cord 32 and the suspension cord 33 are shown in FIG.
As shown in FIG. 3, since a ring 37 is provided at an intermediate portion of the reinforcing cord 32, and the hanging cord 33 is inserted into the ring 37 because the rings 37 overlap at the same position in the in-plane direction.

As a result, even if the reinforcing cords 32, which are tensioned diagonally with respect to the horizontal, and the suspending cords 33, which are tensioned in the vertical direction, are placed at the same position in the in-plane direction, they do not interfere with each other. .

Because of this, the curtain wall tends to bend toward the indoor side when the weight of the inclined curtain wall and the positive pressure due to the strong wind and rain act, but the hanging rope 3
Since it is supported by 3, it does not bend toward the inside of the room.

Further, when a negative pressure such as strong wind and rain acts on the inclined curtain wall, it tends to bend toward the outside, but when the upright 20 tries to bend toward the outside, the support member 3 is formed.
Since the reinforcing cord 32 is pushed through 0 to apply the tensile force, the bending of the upright 20 to the outside of the room is prevented by the reinforcing cord 32, and the inclined curtain wall is exposed to the outside by negative pressure. It is possible to prevent bending.

[0020]

Since the upright 20 is prevented from curving toward the indoor side by the suspending rope 33, and the upright 20 is prevented from curving toward the outdoor side by the reinforcing rope 32, the inclined curtain wall is It is possible to prevent the inner curtain from curving due to its own weight or positive pressure, and to prevent the inclined curtain wall from curving outward due to negative pressure. Further, since the reinforcing cord 32 and the suspension cord 33 are only visible from the outside of the room, the appearance is good.
