Abstract

PURPOSE: To install a mullion or panel in the regular position by swingably arranging a supporting bolt which couples a fastener with a panel side member, and thereby absorbing the constructing error of a mass body of floor and/or the mounting error of a metal piece as anchor. CONSTITUTION: A panel for curtain wall is supported by a supporting device 1 indirectly through a mullion 13. A liner 9 having a convex spherical surface 9a on the indoor side and a universal washer 10 fitted approximately on the spherical surface 9a are installed while a plumb piece 3A of a fastener 3 is interposed. A nut 11 is fitted on a supporting bolt 6 in the condition that another liner 8 having a convex spherical surface 8a on the outdoor side and a universal washer 7 having a spherical surface 7a fitted approximately on the spherical surface 8a are interposed. Accordingly the washers 7, 10 can swing in any direction round the liners 8, 9 while they keep the relative positioning owing to coupling by the bolt 6. Even though the fastener 3 is inclined to a certain degree, supporting can be made in the condition that a bracket 12 and the mullion 13 are vertically supported. This prevents the bolt from loosing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall support structure capable of effectively absorbing a frame construction error, an anchor metal fitting error and the like, and a fitting for the same.

[0002]

2. Description of the Related Art In recent years, in the construction of concrete structures such as buildings, a curtain wall construction method in which ready-made panels are sequentially fitted into the wall surface of the building is becoming mainstream.
In such a curtain wall construction method, for example, as shown in FIG.
As shown in FIG. 2, the anchor metal piece 51 is embedded and fixed in advance in the concrete skeleton 50, the fastener 52 is fixed to the anchor metal piece 51 with the bolt 53, and the upright 56 is attached to the fastener 52. It is fixed by bolts 54 via brackets 55, and a panel is attached to the upright 56. The panel may be directly attached to the fastener 52.

In this case, for example, the upright 56 is vertically provided by passing through the longitudinal direction, but the concrete frame 5 is
When the construction accuracy of 0 or the attachment accuracy of the anchor metal object is poor, the fastener 52 is not installed in a predetermined state but is installed in a slightly rotated state. Therefore, the Bramet contact surface S of the fastener 52 is not vertical, and it may not be possible to bring the bracket 5 into close contact with the bracket 5.

Therefore, as shown in FIG. 10, the fastener 57 has an arcuate curved surface 57a on the bracket abutting surface S so that an arbitrary contact surface (line) can be obtained. Is proposed.

[0005]

However, even in the case of the fastener 57, as shown in FIG. 11, when the fastener 57 is attached with a slight rotation, the fastener 57 and the bracket 55 are connected to each other. In the bolt fastening portion, the bolt head and the nut bearing surface are not parallel to each other, so that a tapered gap T is formed in either one. As a result, the bolt fastening force becomes non-uniform, which causes loosening of the nut, and a bending moment acts as an external force on the bolt screw portion, so that a predetermined bolt proof strength cannot be obtained.

Further, the fastener 57 has a problem in that its manufacturing cost is high because the shape is complicated.

Therefore, the main problem of the present invention is to absorb the construction error of the floor skeleton, the attachment error of the anchor metal fittings, etc.
It is an object of the present invention to provide a curtain wall support structure and a mounting metal fitting for the same that can properly install the upright or panel in a regular arrangement state and can also be well bolted.

[0008]

In order to solve the above-mentioned problems, the present invention provides a curtain wall supporting structure for directly or indirectly supporting a panel using a fastener fixed to the body side as a supporting material, It is characterized in that a support bolt for connecting the panel side member is made swingable.

More specifically, in a curtain wall support structure for directly or indirectly supporting a panel using a fastener fixed to the body side as a support member, a support bolt is provided by inserting the panel side member and the fastener. At the same time, on each side that straddles the panel-side member or the fastener, at least one boundary surface of the fastening nut and the intermediate fittings attached to the support bolt is an arcuate curved surface to allow the support bolt to swing. It is characterized by having done.

In this case, by making the arc-shaped curved surface spherical, the support bolt can swing freely in all directions,
Greater freedom of adjustment. As an example of the mounting bracket used for the curtain wall support structure, for example, a liner material having a convex / concave curved surface and a free washer having a concave / convex curved surface substantially matching the convex / concave curved surface are used as a set. Alternatively, a washer member having a convex / concave arcuate curved surface and a nut member having a concave / convex arcuate curved surface that substantially matches the convex / concave arcuate curved surface can be used as a set. In this case, it is desirable that the convex and concave arc-shaped curved surfaces are spherical surfaces, and at least one surface of these curved surfaces can be subjected to a slipping treatment such as a fluororesin film or a polishing treatment.

[0011]

In the curtain wall support structure according to the present invention, at least one boundary surface between the fastening nut member and the intermediate fittings attached to the support bolt is arcuately curved on each side of the panel side member or the fastener. As a result, the support bolt can swing. Therefore, even if there is a frame construction error or an attachment error of the anchor metal fitting, it is necessary to adjust the uprights, panels, etc. fixed by the support bolts to the normal arrangement state, for example, the vertical state regardless of the fastener installation state. Will be able to. Further, since the bolt fastening force is always uniform and bending is not introduced into the bolt screw portion, a predetermined bolt proof stress is exhibited.

In the present invention, the "fastening nut member and intermediate fittings" mean not only the nut member used for fastening the bolt but also all liner materials inserted in the support bolt. , A washer member, etc.

Further, in the case of the present invention, since the bolt support portion basically has a hinge structure, it is possible to receive deformation due to wind pressure, expansion / contraction due to thermal expansion, and inertial force due to an earthquake. However, stress is not generated or becomes extremely small in the upright or the bolt supporting portion of the panel, and the risk of breakage is extremely reduced.

As shown in FIG. 3, the anchor metal piece 14 embedded in the end of the floor frame F, the fastener 3 attached to the anchor metal piece 14, the fastener 3 and the vertical bracket 12 (hereinafter, referred to as bracket). Bolts 6 for connecting and fastening and intermediate mounting brackets 7 to 11
It is composed of

As the anchor metal piece 14, a ready-made unequal angle angle steel is used. A slot 14a for inserting the anchor bolt 4 is formed in the horizontal flange, and a box body for forming a pocket space M having the slot 14a as an opening on the body side of the horizontal flange. 15 is fixed by welding or the like. The box 14
The space M formed by the
The dimension is set to fit a, and the elongated hole 14a has a width that allows the threaded portion of the anchor bolt 4 to pass therethrough. The anchor bolt 4 is mounted by, for example, a head screw 4 in a state where the bolt screw portion is previously passed through the long hole 14a.
The box 15 is covered so as to surround a, and the periphery of the box 15 is welded.

The fastener 3 is attached to the anchor bolt 4 by the anchor bolt 4. As the fastener 3, a ready-made shaped steel having a L-shaped cross section can be used as well. An elongated hole 3a in the indoor / outdoor direction is formed in the horizontal flange of the fastener 3 so that the fastener 3 can be moved in the indoor / outdoor direction for adjusting the entrance / exit of the panel P. The adjustment of the fastener 3 in the horizontal direction along the wall is performed by moving the anchor bolt 4 together with the fastener 3 using the elongated hole 14a formed in the anchor metal piece 14.

A bolt through hole 3b is formed in the vertical piece 3A of the fastener 3, and the bracket 12 and the fastener 3 are connected to each other.
A support bolt 6 for connecting with and is penetrated through the bolt through hole 3b, and fastening and intermediate mounting brackets 7-1 according to the present invention.
It is fixed by 1.

The bolt fastening structure between the fastener 3 and the bracket 12 in the present invention is a vertical piece 3A of the fastener 3.
With a spherical liner material 9 having a convex spherical surface 9a on the inner side of the chamber and a free washer 10 (see FIG. 4) having a concave spherical surface 10a substantially aligned with the convex spherical surface 9a.
A spherical liner material 8 having a convex spherical surface 8a on the outside of the chamber and a concave spherical surface 7a substantially aligned with the convex spherical surface 8a.
This is done by screwing a fastening nut 11 onto the support bolt 6 with a free washer 7 having
The through holes of the spherical liner members 8 and 9 have a tapered shape that widens outward.

Therefore, while maintaining the relative positional relationship between the universal washers 7 and 10 by the support bolt 6 and the fastening nut 11, the spherical washers 8 and 9 can be swung in arbitrary directions. Because,
Even if the fastener 3 is slightly inclined, the bracket 12 and the upright 13 can be supported vertically. Of course, in the case of this fastening structure, the nut fastening force does not become uneven and the bending moment does not occur in the support bolt 6,
Expected strength of a predetermined bolt. It is generally considered that the swingable angle of the support bolt 6 is about 5 to 10 °.

In the above example, the sliding surface is used as a spherical seat surface so that it can be swung in any three-dimensional direction.
If the swinging direction is limited to one direction, each of the convex spherical surfaces 7a and 9a and the concave spherical surfaces 7a and 10a may be a curved surface in one direction (a chamfered curved surface).

The fastening structure of the support bolt 6 according to the present invention is as follows.
Arbitrary deformation is possible under the condition that the support bolt 6 can swing within a predetermined range. For example, as shown in FIG. 5, the fastening member piece 12a of the bracket 12 is sandwiched between the spherical liner member 9 and the universal washer 10 arranged on the inside of the bracket, and the spherical surface on the outside of the spherical surface. The liner material 8 and the free washer 7 may be fastened with the support bolt 6 and the fastening nut 11 in a state of being arranged.

Further, as in the example shown in FIG. 6, using the spherical liner material 9 disposed on the indoor side surface of the fastener vertical piece 3A as a washer, the fastening has a concave spherical surface 16a substantially aligned with the convex spherical surface 9a. It can also be fastened directly by the nut 16. Further, as shown in FIG. 7, the concave spherical surface 1
Alternatively, the spherical liner 17 having the spherical surface 7a and the free washer 18 having the convex spherical surface 18a may be set as a set and disposed on both sides of the fastener vertical piece 3A, and bolted. Although the through hole of the spherical liner 17 is a so-called stupid hole in the range in which the support bolt 6 can swing in the example shown in the figure, it may be a tapered hole as in the other embodiments.

In any case, according to the present invention, a fastening member, a liner material, a washer member, and the like for fastening and intermediate fittings, which are arranged on both sides of the support material such as the fastener 3 or the bracket 12, are sandwiched therebetween. By making one boundary surface of the class a curved surface, the support bolt 6 can swing. In these cases, it is possible to reduce the friction coefficient of the uneven spherical surface serving as the sliding surface by a fluorine film treatment or a polishing treatment so that the sliding surface becomes slippery.

Next, the present invention can be similarly applied to the panel intermediate supporting device 2 arranged between the floors F and F. In detail, as shown in FIG. 8, the fastener 20 is fixed to the lower surface of the wall material G, and at the time of connection with the intermediate bracket 21, the fastening member piece 20A of the fastener 20 is sandwiched between the interior side thereof. With the spherical liner material 9 and the universal washer 10 disposed on the outside thereof, and with the spherical liner material 8 and the universal washer 7 disposed on the outdoor side thereof, the support bolt 22 is inserted, and the fastening nut 23 is inserted. Conclude by

[0026]

As described in detail above, according to the present invention, even if there is an error in the construction of the floor frame or an error in the attachment of the anchor metal, it can be absorbed and the cube or panel can be placed in a regular arrangement state, for example. It becomes possible to support the vertical or panel in a vertically supported state regardless of the fastener installation state. Further, according to the present fastening structure, the bolt fastening force does not become uneven, and an additional external force such as a bending moment is not introduced to the bolt, so that the bolt can be prevented from loosening and the desired bolt can be prevented. Bolt proof can be expected.
