Abstract

PURPOSE:To moderate stresses against wind pressure loads, by providing a wall body support member, a fixing tool, and a unifying member connecting the fixing tool to a fitting part provided at the wall body support member so as to be rotatable around the fitting part. CONSTITUTION:A wall body support member 2 is fixed in advance to a body 1 and the wall body 3 on which a fixing tool 4 has been fitted in advance in a factory is suspended and nuts 16A, a washer 15A, a rotary member 13A, a distance-reguration member 14, and a bearing member 12A in the outdoor side are fitted to the fitting tool 4 and inserted into a fitting hole 2C. Next, a bearing member 12B, a rotary member 13B, a washer 15B, and a nut 16B are attached to the fixing tool 4 in turn from the indoor side of the fitting part 2b of the support member 2. When the wall body is bent by a wind pressure load F, since the fixing tool 4 is rotatably attached to the support member 2, the fixing tool 4 is rotated with the wall body 3 around the center O of the butt-jointed part of the members 12A, 12B of the fitting part by the unifying member 10 and hence, an extraordinary stress does not act on th. connection part of the wall body 3 and the fixing tool 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall provided on an outer wall surface of a building, and more particularly to a structure for attaching a wall body to a skeleton.

[0002]

2. Description of the Related Art In a curtain wall constructed by mounting a plurality of walls made of glass panels, metal panels, tiles or stones on the outer wall surface of a building, if the walls are attached to the frame by a rigid structure, The stress applied to the wall and its supporting member due to the wind pressure load on the wall increases, and there is a risk that these will be damaged. Therefore, in order to absorb the deformation of the wall body due to the wind pressure load and thereby alleviate the stress generated in the wall body and the supporting member, as disclosed in JP-A-5-248018, a mounting hole provided in the wall body is disclosed. By embedding a spherical bearing in the sphere, and fitting the spherical portion at the tip of the fixture attached to the skeleton into the spherical bearing, when the wall body bends, the spherical portion and the bearing rotate relative to each other. There is one that is designed to reduce the stress acting on the support member.

[0003]

[Problems to be Solved by the Invention] However, in this way,
In a structure where a spherical bearing is embedded in a wall with a limited thickness and the spherical part of the fixture is fitted into this, the structure that does not lose the part protruding from the wall to the outside of the room does not impair the appearance In order to realize a fastener rotating structure in the wall portion having high strength, the spherical surface portion must be precisely processed, and the structure becomes complicated and expensive. Further, such a spherically coupled structure of the wall body has a problem that it is not possible to absorb the vibration in the in-plane direction and the stress acting on the fixture in the in-plane direction cannot be reduced.

In view of the above problems, the present invention can realize a stress mitigation structure against a wind pressure load with a relatively simple structure, which contributes to price reduction, and at the same time stress due to vibration acting on the wall body. An object of the present invention is to provide a curtain wall having a structure that can be reduced.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a wall support member projecting to the outside of the body and a through hole provided in the wall to project the inside of the body. And a coupling member that rotatably couples the fastener to a mounting portion provided on the wall body supporting member so as to be rotatable about the mounting portion.

[0006]

According to the present invention, since the wall body is mounted by the fastener which is rotatable about the mounting portion of the wall body supporting member attached to the body, the fastener can be mounted by the wind pressure load acting on the wall body. The wall supporting member rotates about the mounting portion, and the deformation is absorbed thereby, and the stress acting on the wall and the wall supporting member is relieved. Further, the in-plane vibration of the wall body also absorbs the stress generated by the vibration of the fixture rotating around the mounting portion of the wall body supporting member.

The tapered hole 12f is formed. The interval regulating member 14 has a cylindrical shape that allows the fastener 4 to pass therethrough, and its outer diameter d4 is formed slightly smaller than the minimum diameter d3 of the tapered hole 12f.

The rotating members 13A and 13B have a circular recess 13d whose edge 13c is in contact with the spherical surface 12e of the bearing members 12A and 12B, and a hole 13e having a diameter d5 through which the threaded portion 4a of the fastener 4 can be inserted. It is provided at the center of the bottom of the circular recess 13d.

FIG. 9 is an enlarged cross-sectional view showing a state in which the fastener 4 is joined to the wall body supporting member 2 by the joining member 10, and the wall body 3 is attached to the wall body supporting member 2 in advance.
The wall body support member 2 is fixed to the wall body, and the wall body 3 to which the fixing tool 4 is attached in the factory is hung. The fixing tool 4 has the outdoor nut 16A, the washer 15A, the rotating member 13A, and the interval regulating member. 14, the bearing member 12A is fitted, and the fixture 4 is inserted into one of the corresponding mounting holes 2c to 2f together with the cylindrical portion 12c of the bearing member 12A. Next, the bearing member 12B, the rotating member 13B, the washer 15B, and the nut 16B on the indoor side are sequentially attached to the fixing tool 4 from the indoor side of the mounting portion 2b of the wall body supporting member 2. Then, the screwing positions of the nuts 16A and 16B with respect to the fixing tool 4 are adjusted and tightened so that the wall body 3 is flush with the entire building. Further, the mounting holes 2c to 2f provided in the wall body mounting portion 2b are provided in the bearing member 12
Since it is formed to be larger than the cylindrical portion 12c of A and 12B, it is possible to absorb the mounting error of the wall body supporting member 2 and the mounting error of the fixing tool 4, and it is also possible to adjust the mounting position of the wall body 3 vertically and horizontally. is there.

In this manner, in the state in which the fixing member 4 is attached to the wall body supporting member 2 by the connecting member 10, the spherical surface portion 12e of the bearing members 12A and 12B is the center of the abutting portion of these bearing members 12A and 12B. 1 centered on O
A cylindrical space regulating member 14 which is configured to be a part of the spherical surface 17 of one spherical body and is interposed between the rotating members 13A and 13B is fitted into the tapered holes 12f of the bearing members 12A and 12B ( These two tapered holes 12f
The two tapered holes 12
Since f forms a hole whose both ends are enlarged, the interval regulating member 14 fitted in the hole is rotatable about the point O within a range defined by the taper angle of the tapered hole 12f. ) And the edge 13c of the circular recess 13d of the rotating members 13A and 13B come into contact with the spherical surfaces 12e, the fixing tool 4 rotates about the center O of the tip abutting portions of the bearing members 12A and 12B. Can be freely combined. Further, both ends of the interval regulating member 14 have the rotating members 13A, 1
By contacting the inner surface of the circular recess 13d of 3B, the rotating member 13A,
The contact pressure of the edge 13c of the circular concave portion 13d of 13B with respect to the spherical surface portion 12e does not become excessively strong, and the rotation can be performed smoothly. The sealing material 9 is applied between the wall bodies 3 after the wall body 3 is attached.

As described above, since the fixing member 4 provided on the wall body 3 is rotatably attached to the wall body supporting member 2, as shown in FIGS.
As shown in FIG. 1, when the wall body 3 is bent by the wind pressure load F, the fixing tool 4 rotates together with the wall body 3 around the center O of the abutting portion of the bearing members 12A and 12B of the mounting portion by the coupling member 10. Therefore, excessive stress is not applied to the joint between the wall 3 and the fixing tool 4. Further, in this embodiment, since the tightening force of the nuts 16A and 16B on the mounting portion 2b is relaxed by the interval regulating member 14 and the rotation fulcrum of the fastener 4 can be slid vertically and horizontally, the rotation of the fastener 4 can be prevented. Since the rotation fulcrum O moves along with the movement, the fixing tool 4 can be rotated more smoothly. Also, the wall 3
When vibrations in the in-plane directions indicated by X and Y are applied due to an earthquake or the like, the fastener 4 also rotates around the center O, so that the stress during vibration is relieved.

Although the present invention has been described with reference to the embodiments, the wall body 3, the wall body support member 2, the wall body fixing member 4, and the connecting member 10 other than the above embodiments are within the scope of the present invention. Various changes and additions can be made to the structure and combination of the above, and the present invention can be applied to an oblique wall surface such as a top light.

[0018]

According to the present invention, the fastener attached to the wall is rotatably attached to the wall support member attached to the body through the connecting member, and the relative room inside the wall is relatively large. Since the rotation fulcrum part of the fixing tool is provided in a space with a space, compared to the case where the rotation fulcrum part is provided on the wall body, the fixing tool needs to be attached to the wall body or the wall body supporting member with precision processing. Since it is not necessary to adopt a high precision spherical bearing structure as described above, it can be realized with a relatively simple structure, which can contribute to a reduction in the price of the curtain wall. Further, even when the wall body vibrates in the in-plane direction, since the fixing tool rotates, it is possible to reduce stress due to vibration acting on the wall body.
