[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a so-called curtain wall construction method for a building, which is made of metal used for attaching the wall panel to a building frame such as a steel frame, and is particularly applied to the upper part of the wall panel. It concerns mounting hardware.

[0002]

2. Description of the Related Art Examples of hardware used for a curtain wall construction method include those disclosed in Japanese Examined Patent Publication No. 63-54101 and Japanese Unexamined Patent Publication No. 1-295050. The latter disclosed technology is a division of the former application, and the embodiments are similar.

FIG. 4 and FIG. 5 are a perspective view and a sectional side view showing the mounting structure shown in the above publication, and in the drawings, an L-shaped ruler angle is provided on the upper surface of the beam 1 constituting the steel frame assembly. 2 is attached by means such as welding. Also,
At the bottom of the upper wall panel A, the above L-shaped ruler angle 2
A lower mounting piece 3 for locking and fixing one end side to the vertical flange 2a is bolted. And the lower wall panel B
An upper mounting piece 4 whose one end side is supported between a metal piece described later and a vertical flange 2a of the L-shaped ruler angle 2 is bolted to the upper part of the.

Reference numeral 5 is a U-shaped metal piece (U-shaped piece) in plan view, and both side plates 5a, 5a of the U-shaped piece 5 are provided with a cut groove 5c from below. The cut groove 5c is meshed with the vertical flange 2a of the L-shaped ruler angle 2 to form a space 6 between the vertical flange 2a and the vertical flange 5b of the bending piece 5, into which the upper mounting piece 4 is inserted. I have to. Reference numeral 7 is a load receiving angle that supports the load of the upper wall panel A, and is attached to the L-shaped ruler angle 2.

In the above structure, the width of the insertion portion of the upper mounting piece 4 of the lower wall panel B is made smaller than the width of the space 6, so that the upper mounting piece 4 slides in the surface direction in the space 6. When the earthquake occurs, the upper part of the wall panel B slides relative to the sill 1 so as to follow the interlayer displacement.

[0006]

In the above-mentioned mounting hardware, although it is generally processed and shaped in terms of size and shape, the surface remains a so-called black skin,
It is a fairly rough surface.

When using such a metal object, it is necessary to consider the deterioration of the curtain wall function over time. Particularly, when another slidable metal object (upper mounting piece 4) is arranged in the predetermined space 6 as in the above-mentioned reference example, in order to prevent unnecessary rattling of the upper mounting piece 4 in the out-of-plane direction, the upper mounting The space 6 for accommodating the piece 4 is designed so that a gap of, for example, about 1 mm remains after accommodating the upper mounting piece 4.

However, in the case where the gap 6 is designed to be contained in a constant value, the gap is so small that when the rust is generated due to aging, the upper mounting piece 4 and the upper mounting piece 4 become U-shaped pieces together with the rough surface. 5 or the surface of the L-shaped ruler angle 2 such as the vertical flange 2a is almost joined to the surface, which may cause troubles such as hindering smooth sliding. Also, depending on the distortion of the upper mounting piece 4,
Together with the rough surface and the like, the contact frictional resistance with the inner surface of the void becomes significantly large, and there is a concern that the function as a curtain wall may be impaired.

Further, the space 6 has a vertical flange 5b of a U-shaped piece 5 which meshes with the vertical flange 2a of the L-shaped ruler angle 2.
Unless the position and the size of the cut groove 5c are accurately machined, the set size varies and the upper mounting piece 4 is sandwiched and the intended purpose cannot be achieved.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a mounting hardware capable of exhibiting a curtain wall function with good performance over a long period of time. is there.

[0011]

[Means for Solving the Problems] In order to achieve the above object,
The present invention is a metal fitting that is slidably engaged with and supports a strip-shaped upper plate mounted on an upper portion of a wall panel by being locked to a support angle mounted on a building frame, and houses the upper portion of the upper plate. An engaging groove that protrudes in one direction on the intermediate side surface from the upper part of the void of the box-shaped body forming the void in plan view and engages with the standing piece of the support angle is opened downward between the side face of the box-shaped body. The box-shaped body is formed by smoothing the inner surface of the box-shaped engaging piece.

In this case, the engaging piece has an engaging groove which is protruded from one side surface of the box-shaped body which forms a space having an elongated shape in a plan view for accommodating the upper portion of the upper plate and engages with the standing piece of the support angle. It is also conceivable that the inner surface of the box-shaped body is finished so as to be formed so as to open downward between the side surface of the box-shaped body.

In any case, the smooth surface is formed by a plating layer, a fluorine resin layer, or the like, in addition to processing such as grinding.

[0014]

The size of the air gap, which is slightly larger than the upper plate thickness of the upper plate and whose width dimension is set within the slide allowance range of the upper plate during an earthquake, can always be kept constant as a box. Therefore, even if there is some unevenness on the support angle surface, the void accuracy is affected, and the quality is stable. Moreover, by smoothing the inner surface of the box-shaped body, the upper plate is reliably compensated for sliding during an earthquake. In this case, when the smooth surface is formed by the plating layer or the fluorine-based resin layer, the function at the time of the earthquake can be more reliably exhibited, and the durability such as the rust prevention effect can be further improved.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing the configuration of a mounting hardware and a member to be mounted, FIG. 2 is a sectional side view showing a mounting state of a wall panel, and FIG. 3 is a plan view of FIG. 2 in which the wall panel is omitted.

In the figure, reference numeral 10 is a mounting hardware main body, which is composed of a combination of a box-shaped body 11 and an engagement piece 12. The box-shaped body 11 includes two rectangular face plates 11a and 11a.
Are joined to each other at two ends to form a space 13 having an elongated shape in plan view therebetween. The gap 13 is set to a size to accommodate an upper portion 20a of the upper plate 20 described later, and the thickness thereof is, for example, about 1 mm from the plate thickness of the upper plate upper portion 20a.
It is thick and the width is set within a range that allows the upper plate upper portion 20a to slide during an earthquake. The face plate on the side from which the engaging piece 12 to be described later projects out of the face plate 11a uses a thinner plate thickness than the other.

Therefore, the inner surface 11b of the box-shaped body 11 forming the void 13 is finished to be smooth. The smooth surface does not remain in the so-called black skin state, but is obtained by processing. For example, in addition to grinding, plating is used, or fluorine resin coating is used. The cross-sectional view of FIG.
2 shows a state in which a smooth layer such as the plating layer is formed on the inner surface 11b.

The engaging piece 12 has a hook shape in a side view, and has a box shape 1.
One face plate 11 above the void 13 on the intermediate side surface of
One end is abutted against the other face plate 11a penetrating through a and the end portion and the penetrating portion are fixed by welding. That is, box shape 11
The upper surface of the void 13 protrudes in one direction on the intermediate side surface. And, the protruding side of the engagement piece 12 has a face plate 11a.
An engaging groove 14 having a required width is formed between the and and by opening downward. The opening width of the engaging groove 14 is set to be slightly larger than the plate thickness of the standing piece 31 of the support angle 30 that is previously attached to the building frame H. Slightly larger size means vertical piece 3
The size is such that it allows the clearance between the face plate 11a and the upright piece 31 so as not to interfere with the welding work, as will be described later.

The upper plate 20 is attached to the upper part of the inner wall surface of the wall panel P ₁ , and is formed of a rectangular flat plate. This is the mounting portion of the wall panel P ₁ of the upper plate 20 by attaching a添板21, as shown in FIG. 2, other wall panels located in the wall panel P ₂ Toka left and right upper wall panel P ₁ The outer surface of the wall is adjusted to be flush with the above. Therefore, if the upper plate 20 is formed in a strip shape into a so-called lightning plate, the attachment plate 21 is unnecessary.

Needless to say, the upper plate 20 can be attached not only to the wall panel P ₁ but also to the above-mentioned upper wall panel P _2, left and right, or the upper portion of the lower wall panel. In addition, a conventionally known appropriate lower-side mounting metal piece is provided at the lower portion of each wall panel, and is attached to the corresponding support angle 30 by appropriate means.

In the above structure, the wall panel P ₁
When attaching to the building skeleton H, first, the supporting asoglue 30 is positioned and attached at a required position of the building skeleton H by a level or the like. The support angle 30 has its base piece 32 firmly attached to the building frame H by welding or the like. And the wall panel P ₁
In addition to the lower mounting hardware, attach the upper plate 20 to the bolt B
Attach by

Thereafter, the wall panel P ₁ is set up against the standing piece 31 of the support angle 30, and the upper portion 20a of the upper plate 20 is brought into contact with the standing piece 31. Next, the metal body 10 is engaged with the engagement piece 12 of the metal piece 10 on the standing piece 31,
The upper portion 20a of the upper plate is provided in the space 13 of the box-shaped body 11.
So that it will be accommodated. In this insertion, when the upper plate 20 is in contact with the upright piece 31 of the support angle, one face plate 11a of the box-shaped body 11 along with the upright piece 31 abuts against the upper end of the upper plate 20. The upper plate 20 can be inserted by slightly separating it from the standing piece 31. Also, the upper plate 2
By chamfering the end of the upper portion 20a of 0, the insertion can be performed more smoothly.

After the insertion, the appropriate portions for fixing the abutting portion between the upper end of the standing piece 31 and the face plate 11a of the box-shaped body 11 are welded and joined. This completes the work of attaching the upper part of the wall panel.

Incidentally, when welding the metal body 10 and the support angle 30, welding spatter is conventionally scattered and adhered to the upper plate accommodating space, and in extreme cases, it may be a factor that hinders sliding of the upper plate during an earthquake. There was a problem. However, according to the configuration of the present invention, the gap 13 is the box-shaped body 11, and the support angle engaging depth of the engaging groove 14 is set by the engaging piece 12 near the upper and lower intermediate portions of the face plate 11a. It is possible to prevent welding spatter from scattering and adhering to the inside of the gap 13 when welding the contact portion between the support angle 30 and the box-shaped face plate 11a.

Next, in the present invention, the structure of the mounting device can be changed without departing from its intended purpose. For example, in the above-described embodiment, one end of the engagement piece 12 is arranged so as to face the upper portion of the space 13 of the box-shaped body 11 and is welded and fixed to both face plates 1a. In this way, the wall panel P
_Since the proof stress of the face plate 11a against the wind pressure and the like applied to _{No. 1} is improved, it is suitable for use in a large-sized wall panel or the like.
However, if the wall panel of a small plate or the thickness of the face plate 11a is appropriately set, it is possible to project the engaging piece 12 from the side surface of one face plate without facing the gap 13.

Further, not only one of the engaging pieces 12 is projected from the intermediate side surface of the box-shaped body 11 as in the above-described embodiment, but it is also extended and projected from both end sides of one face plate 11a. Of course, a plurality of sheets may be provided with an appropriate configuration.

[0027]

As described in detail above, according to the present invention, since the void of the metal body for accommodating the upper part of the upper plate is formed by the box-shaped body, it affects the construction condition and quality of the support angle. It can be used as a metal product with a constant void size.

Further, since the inner surface of the box-shaped body with which the upper plate comes into contact is made smooth, there is no fear of disturbing the smooth operation of the upper plate in the event of an earthquake, and the curtain wall function can be retained more reliably.
