BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall mounting structure, and more particularly to a curtain wall mounting structure capable of favorably supporting the curtain wall in any of rocking, sway and spandrel supporting modes.

[0002]

2. Description of the Related Art There are various types of conventional curtain wall mounting structures, such as rocking, sway, spandrel, etc., corresponding to various supporting modes.
There is one disclosed in Japanese Patent No. 8743. In this proposal, the curtain wall is attached so that it can be moved slightly with respect to the building body side, so that the vibration generated by an earthquake or a strong wind escapes at this attachment part and prevents the curtain wall from cracking. Has become.

By the way, as the mounting structure of the curtain wall, various structures are adopted depending on the input direction of vibration, and as shown in FIG. 5, for example, the swinging in the surface direction about the shape center O of the curtain wall 1 ( There is a so-called loose rocking support system that rotatably supports the X direction). In this rocking support, the displacements of the upper and lower corners of the curtain wall appear as vertical displacements with respect to the normal vibration input. Therefore, the corners are supported by the mounting structure shown in FIG. There is something I did.

That is, in the mounting structure of FIG. 6, the curtain wall 1 formed of a PC plate is integrally provided with a mounting bracket 2 formed of an angle member, and one end of the mounting bracket 2 is projected in the horizontal direction. On the other hand, the support bolts 4 are erected on the beam members 3 provided on the body side of the building. Then, a hole 5 is formed in the protruding portion 2a of the mounting bracket 2, a guide plate 6 is fixed to the upper surface of the protruding portion 2a, and the support is provided at a position corresponding to the hole 5 of the guide plate 6. A guide hole 6a having a diameter substantially equal to the outer diameter of the bolt 4 is formed, and the support bolt 4 is inserted into the guide hole 6a.
I am trying to insert it. With such a structure, the lower end of the curtain wall 1 can be displaced vertically while restricting its horizontal movement.

At the upper end of the support bolt 4, an appropriate space is provided to allow relative displacement with the mounting bracket 2,
A retaining nut 7 is screwed into the support bolt 4
A large number of liners 8 are inserted between the seat surface 9 to which the brackets are attached and the attachment brackets 2, and the height of the curtain wall 1 with respect to the beam member 3 is adjusted by these liners 8.

[0006]

However, in such a conventional curtain wall mounting structure, the height of the curtain wall 1 is adjusted by the liner 8. Therefore, the height of the curtain wall 1 is adjusted by the liner 8. To do this, lift or lower the curtain wall 1 to the left,
The liner 8 will be attached while keeping the right balance. Therefore, the work of adjusting the height of the curtain wall 1 is extremely complicated.

When the curtain wall 1 is vertically displaced with respect to the building frame, the guide holes 6a are relatively slid vertically along the height direction of the support bolts 4. At this time, the threaded portion 4 is formed on the outer circumference of the support bolt 4.
Since a is formed, prying is likely to occur between the support bolt 4 and the guide hole 6a. Therefore, if twisting occurs between the support bolt 4 and the guide hole 6a, relative movement of the mounting portion in the vertical direction is blocked, and the proper support function of the curtain wall 1, such as the locking function of the curtain wall 1, is impaired. There were various problems that the vibration input to the building could not escape.

In view of the above-mentioned conventional problems, the present invention can easily adjust the height position of the curtain wall and surely assure the supporting function of the curtain wall. The purpose is to provide.

[0009]

In order to achieve the above object, the present invention provides a mounting bracket which is provided at a corner portion of a curtain wall so as to project in a horizontal direction from the corner wall and which has a guide hole penetrating vertically. A support bolt provided on the side of the building body and loosely inserted into the guide hole of the mounting bracket to support the curtain wall, and a tubular body that is screwed to the support bolt and covers the outer periphery thereof,
And a sleeve having a locking portion that supports the load while the mounting bracket is positioned on the support bolt by being detachably engaged with the mounting bracket from below.

[0010]

With the above construction, in the curtain wall mounting structure of the present invention, by rotating the sleeve screwed to the support bolt, this sleeve changes its axial position with respect to the support bolt, Along with this, the height position of the mounting bracket locked to the locking portion of the sleeve can be adjusted and supported. That is, the curtain wall can be positioned and adjusted only by rotating the sleeve, and the curtain wall mounting operation is significantly simplified.

Further, when relative displacement occurs between the mounting bracket and the support bolt due to vibration input, relative movement is performed between the outer circumference of the sleeve screwed to the support bolt and the inner circumference of the guide hole. The relative displacement can be smoothly performed.
