Abstract

PROBLEM TO BE SOLVED: To provide a fastener capable of efficiently carrying out fixing work of a curtain wall to a skeleton while preventing a washer falling from a high place in a building. SOLUTION: The fastener 1 includes a fitting 11 fixing to the curtain wall (precast concrete plate 22) to be fixed to the skeleton 21, a bolt 12 mounted to the fitting 11 and the washer 13 inserted into the bolt 12 incapable of falling down and in a vertically slidable manner.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener which is a supporting metal used for fixing a curtain wall to a frame in a building.

[0002]

2. Description of the Related Art Conventional fasteners of this type include, for example, a mounting hardware fixed to a precast concrete plate as a curtain wall to be fixed to a frame, a bolt mounted on the mounting hardware, and a bolt mounted on the mounting metal. And a washer that is slidably inserted up and down.

According to such a fastener, not only can the curtain wall be fixed to the frame in the building, but also the interlayer displacement occurring on the upper and lower floors in the building after the construction can be absorbed.

[0004]

However, in this type of fastener, since the bolt and the washer are separate parts, when mounting the precast concrete plate to the frame, there is a danger that the washer is attached to the bolt. He was forced to work at high places.

[0005] In addition, the work of mounting the washer under such an unstable situation is apt to cause an error of the operator, and therefore,
There is a great risk that the washer will fall from a high place, which is dangerous for workers on the ground and the like and third parties.

Therefore, an object of the present invention is to provide a building
An object of the present invention is to provide a fastener that can efficiently fix a curtain wall to a frame while avoiding a situation in which a washer falls from a high place.

[0007]

That is, a fastener according to the present invention comprises: a mounting member fixed to a curtain wall to be fixed to a frame; a bolt mounted to the mounting member; And a washer which is slidable and is fitted so as not to fall.

According to the fastener according to the present invention, since the washer is slidable up and down with respect to the bolt and is inserted so as not to be dropped, the curtain is prevented from dropping from a high place in a building. The work of fixing the wall to the frame can be efficiently performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. FIG. 1 is a perspective view showing a schematic configuration of a fastener according to an embodiment of the present invention (FIG. 1A is an overall view, and FIG. 1B is a partial view).

In the present embodiment, the fastener 1 is
As shown in FIG. 1, it comprises a mounting hardware 11, bolts 12, and washers 13.

Here, the mounting hardware 11 is fixed to a precast concrete plate 22 which is a curtain wall to be fixed to the frame 21.

More specifically, the mounting hardware 11 includes a pair of right-angled triangle members 11a extending from the precast concrete plate 22 at a predetermined interval, and extends over a bottom portion of the vertical members 11a. And a horizontal member 11b. At approximately the center of the horizontal member 11b, a screw hole 11c having a female screw into which the bolt 12 fits is provided.

The bolt 12 is attached to the mounting hardware 11. At the upper part of the bolt 12, a male screw 12a that fits into the female screw of the screw hole 11c of the horizontal member 11b is provided.

On the other hand, a washer 1 is provided below the bolt 12.
Outer ring 12 as a technical means to prevent the falling of
b is fixed (see FIG. 1 (b-1)). here,
The technical means for preventing the washer 13 from falling is not limited to the outer peripheral ring 12b.
It may be appropriately selected from those using b '(see FIG. 1 (b-2)), those using split pins, those using idling, and the like.

Further, the washer 13 is slidable up and down with respect to the bolt 12, and is fitted so as not to drop.
That is, the washer 13 is basically configured to be slidably inserted into the bolt 12 up and down.
The above-mentioned ring makes it impossible to fall.

That is, the work of fixing the precast concrete plate 22 to the skeleton 21 using such a fastener 1 is performed by crane operation and guidance of a companion worker while the precast concrete plate 22 is mounted on the ground in advance with the washer 13 mounted in advance. It is configured to include a work of dropping the bolt 12 attached to the mounting hardware 11 on the 22 side into another fastener 23 on the skeleton 21 side.

Therefore, the fastener 1 according to the present embodiment.
According to this, the precast concrete plate 22 is fixed to the frame 21 because the washer 13 is slidable up and down with respect to the bolt 12 and is inserted so as not to fall, and the bolt 12 and the washer 13 are not configured as separate parts. Work can be done efficiently and safely.

[0018] Therefore, when the precast concrete plate 22 is fixed to the frame 21, there is no possibility that the washer 13 will fall from a high place.

[0019]

According to the fastener according to the present invention, since the above structure is adopted, the work of fixing the curtain wall to the frame can be efficiently performed while avoiding the situation where the washer falls from a high place in the building. It becomes possible.
