Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a mounting hardware used when attaching a wall panel to a steel frame in the so-called curtain wall construction method.

<Prior art> When installing the wall panels of a curtain wall type building on a steel frame, it is necessary not only to safely support the panel load, but also to
In order to prevent the sushi from cracking or falling off due to the displacement of the steel frame structure caused by shaking during an earthquake, it is supported with mounting hardware that has the ability to follow the displacement between the floors.

Japanese Patent Publication No. 63-54101 is a specific example showing the structure of the above-mentioned mounting hardware.

4 and 5 are a perspective view and a cross-sectional side view showing the structure of the mounting hardware disclosed in the above publication.

In the figure, on the top surface of the steel beam l that makes up the steel frame,
An L-shaped ruler angle 2 whose lower end forms a flat surface perpendicular to the wall panel surface is attached by means such as welding. Further, a lower mounting piece 3 is bolted to the lower part of the upper wall panel A, and the lower mounting piece 3 locks and fixes one end to the vertical flange 2a of the above-mentioned overhanging ruler angle 2. and,
An upper mounting piece 4 is bolted to the upper part of the lower wall panel B, one end of which is supported between a hardware item to be described later and a vertical flange 28 portion of the L-shaped ruler angle 2.

Reference numeral 5 denotes a hardware (U-shaped piece) that is approximately U-shaped in plan view, and both side plates 5a of this U-shaped piece 5 are provided with grooves 5 cut from below.
c is formed. The cut groove 5c is dimensioned to mesh with the vertical flange 2a of the L-shaped ruler angle 2, and when the mesh is engaged, the upper mounting piece 4 is inserted between the vertical flange 2a and the vertical flange 5b of the U-shaped piece 5. The air gap 6 is formed so that it is possible to do so. The load receiver 7 is an angle, and is attached to the vertical flange 2a of the L-shaped ruler angle 2 to support the load of the upper wall panel A.

In the above structure, the lower mounting piece 3 of the upper wall panel A is engaged with the vertical flange 2a of the L-shaped ruler angle 2 and fixed by welding or the like. Furthermore, by making the width of the insertion portion of the upper attachment piece 4 of the lower wall panel B smaller than the width of the gap 6, the upper attachment piece 4 can slide in the surface direction within the gap 6, and thereby During an earthquake, the upper part of the wall panel B slides relative to the steel frame assembly to follow the interstory displacement, thereby absorbing the earthquake load.

(Problems to be Solved by the Invention) The conventional techniques described above have a problem in that the construction work becomes complicated.

That is, as a mounting hardware for wall panels, L-shaped ruler angle 2. Lower mounting piece 3. In addition to the upper mounting piece 4, the U-shaped piece 5 for forming the gap 6 and the angle 7 for the load receiver that receives the wall panel A are also required, so the number of hardware parts required for the installation work is quite large. Become.

Therefore, in addition to the problem of man-hours, since each part engages, it is a complex structure that is likely to cause problems in terms of engagement dimensional accuracy between parts, etc. in order to ensure a reliable and uniform installation. There is.

Furthermore, the disclosed technology has a problem in that it is difficult to easily and uniformly adjust and set the mounting height position of the wall panel, the surface direction entrance/exit positioning, etc. for each mounting location.

For example, Japanese Utility Model Publication No. 82-27801 discloses a method that enables positioning adjustment in a curtain wall, in which a wall panel mounting tool that engages with an L-shaped stopper fixed to a steel beam is proposed. Disclosed is a method using an adjusting tool such as a bolt so that the position tWJ can be adjusted from both the front and rear sides, or from both the left and right sides. However, even with this method, the installation position of the bolts must be determined in relation to other adjacent wall panels, etc. IJJs require considerable skill in controlling the amount of screwing, etc., and it is difficult to perform positioning easily and accurately with good workability, and it also requires considerable effort.

The present invention was developed in view of the above-mentioned conventional problems.The purpose is not only to simplify the work of installing wall panels at construction sites, but also to
It is an object of the present invention to provide a mounting hardware which allows positioning etc. to be performed reliably and uniformly on each wall panel without requiring special effort.

<Means for Solving the Problems> In order to achieve the above object, the mounting hardware according to the present invention includes a base hardware that has an abbreviated shape in side view that is attached to the upper surface of a steel beam of a steel frame body, and a base hardware that is attached to the upper surface of the inner surface of a wall panel. The upper part of the hardware is attached with a part protruding and is narrower in width than the base hardware, and has an approximately rectangular appearance, and the back plate is attached to the lower part of the inner surface of the wall panel and is wider than the base hardware. A plurality of bolt insertion holes are drilled, and at least one of them is formed with an insertion groove that opens on the upper side, and the back plate and the sleeve plates on both sides form a three-dimensional shape when viewed from above. An angled support plate is installed between both sleeve plates at an appropriate distance from the back plate to form a space for accommodating the base upright piece of the base hardware and the protruding hook part of the upper metal piece, and the support plate It consists of a lower metal fitting formed by screwing a presser bolt and a height adjustment bolt into the vertical piece and the horizontal piece, and a latching part of the upper metal fitting is slidably accommodated in either the base metal fitting or the lower metal fitting. A stopper is provided to define the gap.

According to the above, the gap between the base vertical piece of the base hardware and the back plate of the lower hardware is adjusted and set using the holding bolt of the angled support plate, and the height position of the lower hardware relative to the base hardware is adjusted and set using the height adjustment bolt. Finally, the base hardware and lower hardware are appropriately welded and fixed.

<Function> Displacement of the steel framework in the living room due to an earthquake or the like will also affect the wall panels that are attached to the steel beams of the framework and supported via hardware. However, among the mounting hardware, the upper part of the upper part is slidably supported between the base part and the lower part. Even if it follows the beam and is displaced, the upper metal fittings will not slide and displace. In other words, the wall panel as a whole absorbs the displacement of the steel frame as a whole by the metal fittings, so there is no damage such as cracking or peeling. can be avoided.

To attach the wall panel to the steel frame, the base piece of the base hardware positioned and fixed to the steel beam is brought into contact with the hooking part of the upper hardware previously attached to the wall panel located at the lower layer.

Next, the lower metal fitting before being attached to the upper wall panel is placed over the space formed inside so as to accommodate the base upright piece and the hook, and the lower wall panel is temporarily fixed.

Then, screw the presser bolt and height adjustment bolt into each bolt hole of the angle-shaped support plate of the lower metal fittings, and screw the presser bolts until the base vertical piece and the back plate of the lower metal piece come in contact with the stopper, and then adjust the height. Screw the adjustment bolts to the specified height. After this, suspend the upper wall panel from the back plate of the lower hardware, align the specified bolt holes on the wall panel with the mounting port insertion holes on the back plate, and install. Tighten the lower hardware and wall panel by screwing in the bolts.

In this case, by temporarily fastening the mounting bolt to the bolt hole of the wall panel corresponding to the insertion hole of the mounting bolt, it is possible to guide the bolt shaft to the insertion groove during the alignment. and can make your work easier.

After the above operations are completed, the base metal fittings and the lower metal fittings are joined and fixed at required positions such as abutting portions or adjacent portions by means such as welding. Thereby, the hook part of the upper hardware is slidably supported within the gap defined by the stopper between the base upright piece of the base hardware and the back plate of the lower hardware.

In this way, it is possible to adjust the mounting height, entrance/exit, etc. of the wall panel with a simple operation and perform installation work with high precision.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

1 to 3 show mounting hardware according to an embodiment of the present invention, and FIG. 1 is a perspective view of the structure in partial cross section;
FIG. 2 is an assembled sectional side view showing the state in which the wall panel is attached, and FIG. 3 is a front view of FIG. 2.

In the figure, 10 is the base hardware, 20 is the upper hardware that is attached to the upper part of the wall panel L (see Figure 2) located on the lower layer, and 30 is the lower hardware that is attached to the lower part of the wall panel H that is located on the upper layer. be.

The shape and configuration of each hardware will be explained below.

First, the base hardware 10 is attached to the upper surface of the steel beam 1 of the steel frame, and includes a bottom piece 10a and a base vertical piece 10b.
A mounting bolt insertion hole 11 is formed approximately in the center of the base 10a and is elongated in a direction perpendicular to the surface of the base vertical piece 10b. As a result, when attaching the base hardware 10 to the steel beam l, as described later, the mounting bolt insertion hole 11 is inserted into the mounting bolt (stud bolt) 12 erected at a desired position on the upper surface of the steel frame if, and the nut is inserted. I try to tighten it at 13. After the above-mentioned tightening, in order to strengthen the installation, it is desirable to connect and fix it to the steel beam l by means such as welding. This is a stopper provided, and is made to protrude by a predetermined amount in a direction that defines a storage gap when supporting a hook part of an upper metal fitting 2o, which will be described later, with a lower metal fitting 30.

The upper hardware 20 has mounting bolts 2 attached to the upper part of the inner surface of the wall panel L located in the lower layer with a part protruding from the upper side thereof.
1, and is formed into a generally rectangular shape in appearance. Therefore, the attachment part 20a to the wall panel L is made thicker than the above-mentioned protruding part, and has a level of entry and exit with respect to the thickness of the lower hardware 3o of the upper wall panel H when attached to the steel beam 1, which will be described later. In the case of the example shown in Figure 0, the plate thickness is adjusted by integrally joining the splint plate 22 to the attachment part 20a, but the plate thickness is adjusted by processing the plate into a stepped shape, or It is also possible to bend the intermediate portion into a so-called lightning shape.

The protruding portion of the upper hardware 20 is a hook portion 20 that is supported by the base hardware 10 and the lower hardware 30, which will be described later.
b.

The lower hardware 30 is attached to the lower part of the inner surface of the wall panel H located on the upper layer using poles 31a and 31b.

It receives and supports the load of the wall panel H, and is formed into a U-shape in plan view by a back plate 32 that serves as a mounting surface and sleeve plates 33 that protrude from both sides of this back plate 32 in a substantially perpendicular direction. are doing. Mounting port insertion holes 34a and 34b are formed at appropriate intervals on the upper surface of the back plate 32. In this case, the insertion hole 34b is formed in the shape of a groove opening on the upper side of the back plate 32 (hereinafter referred to as the "insertion groove 34b"), and the above-mentioned interval is as follows:
The mounting positions of the mounting bolts 31a and 31b of the wall panel H are the same as the mounting positions of the mounting bolts 31a and 31b.

Reference numeral 35 designates an angled support plate extending between the inner surfaces of the sleeve plates 33, 33, and is constructed so that its vertical piece 35a forms a space 36 with an appropriate interval between it and the back plate 32. There is. The above-mentioned interval dimension of the space 36 is the same as that of the base hardware 10.
The dimensions are such that the base vertical piece tab and the hooking part 20b of the upper hardware 2o can be accommodated, and in the case of the embodiment, the stop collar 14 is formed on the base vertical piece 10b, so when the stopper 14 is housed, the stop/pa end The dimensions are such that there is a gap of about 2 to 3 mm between the two.

The vertical piece 35a and the horizontal piece 35b of the support plate 35 each have an appropriate number of bolt holes 37a for the presser bolts 37.
In the example shown in Figure 0, in which a bolt hole 38a for the height adjustment bolt 38 is formed, a through hole is bored in the support plate 35 and a nut is fixed to the surface of the hole to form a bolt hole, but the plate thickness of the support plate 35 If the through-hole is sufficient, the through-hole may be a bolt hole formed by threading.The bolt holes 37a for the holding bolts are provided at two locations with an interval slightly narrower than the width of the base vertical piece 10b of the base hardware IO. There is. Further, the bolt hole 38a for the height adjustment bolt is located between the horizontal piece 35b and the base hardware 10.
It is provided in a position that does not interfere with the mounting port insertion hole 11 of the.

39 is a reinforcing plate, which is attached to the inner side of the back plate 32,
The back plate 32 is designed to have increased bending rigidity against loads received by earthquakes and the like. This reinforcing plate 38 is not necessarily required as long as the thickness of the back plate 32 is sufficient for the above load.

In addition, the base vertical piece 10b of the base hardware IO and the upper hardware 2
0 and the sleeve plate 33 of the lower hardware 30.

With respect to the respective widths, when the base vertical piece 10b is used as a reference, the hook portion 20b is narrower than the base vertical piece 10b, and the width between the sleeve plates 33 is wider. The dimensional proportions of these widths are as follows:
In b, it is sufficient that the stoppers 14 on both sides thereof are accommodated between the sleeve plates 33 of the lower hardware 30, and the above-mentioned latching portion 20b is free within the range between the stoppers 14 on both sides of the base upright lOb during an earthquake action, which will be described later. The width is wide enough to allow for sliding.

Each hardware item 10.20. has the above configuration.
30 to attach the upper and lower wall panels H and L to the steel beam l of the steel frame structure will be described below.

First, the surface of the base vertical piece 10b of the base hardware 10 is made parallel to the longitudinal direction of the steel beam l, that is, parallel to the surfaces of the wall panels H and L, and the stud port insertion hole 1 of the bottom piece 10a is
1 is placed on the steel beam by aligning it with the stud port 12 on the top surface of the steel beam. And base vertical piece 10 from steel beam 1
Adjust the entrance and exit of b and tighten the nut 13. In this case, the steel beam 1 and the bottom piece 10a are firmly connected and fixed by welding or the like so that the base hardware 10 does not shift inadvertently after the installation.

Next, the lower wall panel L, which has been attached to the upper part of the inner surface with the upper hardware 20 (attached to the upper part) 21, is erected by placing the lower end on the foundation, for example, if it is for the first floor of a building, and then using a crane or The hooking portion 20b of the upper hardware 20 is brought into contact with the base upright piece iob of the base hardware 10 by operating a rope or the like.

Along with the above-mentioned abutment, the lower hardware 30 is
6 so as to accommodate the base upright piece lOb and the hooking part 20b. As a result, the base upright piece 10b and the hanging part 20b are sandwiched between the back plate 32 of the lower hardware 30 and the upright piece 35a of the angled support plate 35, and from now on, the rope at the upper hardware 20 portion of the wall panel L is Even if the abutment presser is released, it will be supported by the lower hardware 30. That is, it is in a temporarily fixed state.

After the above temporary fixing or in advance, the angle-shaped support plate 35
A presser port 37 and a height adjustment port 38 are screwed into the bolt holes 37a and 38a, respectively. And presser porto 3
By bringing the tip of 7 into contact with the base upright piece 10b and pressing it, the back plate 32 of the lower hardware 30 is drawn through the angular support plate 35 until it abuts against the stopper 14 of the base upright piece 10b. Due to this contact, a gap 36a is formed between the back plate 32 and the base upright piece 10b by the amount defined by the stopper 14, which accommodates the hooking part 20b of the upper hardware 20. This specified amount (dimensions) can be determined by
For example, it is preferable that the so-called contact dimension of mutual surface contact forms a gap of about 11 mm at most, rather than zero.

Further, the height adjustment bolts 38 are arranged so that when the upper layer wall panel H is attached to the lower metal fitting 30, a joint M of a predetermined width is formed between the height adjustment bolt 38 and the lower layer wall panel L.

The mounting level of the lower hardware 30 is adjusted by bringing the tip into contact with the bottom piece 10a of the base hardware 10.

After the above settings, the upper layer wall panel H lifted by a crane etc. is attached to the lower hardware 3 at the specified mounting position on the lower part of the inner surface.
Align and attach it to the back plate 32 of 0. in this case,
Since a mounting port insertion groove 34b is formed in the back plate 32, the mounting port 31a is pre-installed into a bolt hole at a predetermined mounting position on the wall panel H side corresponding to this insertion groove 34b.
loosely, that is, only the tip of the bolt screw shaft is screwed together, and during the above positioning, the wall panel H is positioned on the lower hardware 30 by inserting the corresponding mounting hole 31a using the insertion groove 34b as a guide. do. After that, the mounting port 31a and the mounting port 31b are screwed into the wall panel H through the other mounting port insertion hole 34a and tightened.

Washers 41a and 4 are attached to the mounting bolts 31a and 31b.
1b, and the bolt and washer are joined by boiling welding or the like. Furthermore, the backing material 42 is welded and fixed to the back plate 32 while abutting against the washer 41a and covering the mounting port insertion groove 34b. As a result, the mounting port 31a,
Unexpected displacement from the back plate 32 in the direction of the insertion groove can be prevented.

In addition, the above pol)! When tightening, in order to prevent the bolts from loosening inadvertently, it is good to weld the washers 41a, 41b and the back plate 32 together, but if the washers are rectangular as on the opening side, If there is a rotational obstacle around it, it can also prevent rotation. As an obstacle, on the mouth side, the reinforcing plate 39 of the back plate 32 on the side of the washer 41b
The washer 41a side uses a backing material 42.

Furthermore, if the washers 41a, 41b and the back plate 32 are not bonded and fixed as described above, normally the mounting port insertion hole 34
Since the insertion diameter of the mounting port insertion groove 34b is slightly larger than the bolt shaft diameter, as will be described later, when the lower hardware 30 and the base hardware 10 are integrally joined, the lower hardware 30 When an unexpected displacement force occurs between the wall panel H and the wall panel H, the displacement force can be absorbed to some extent by the gap created by the diameter difference.

However, after completing the installation settings for each of the above hardware,
For example, the base metal fitting 10 and the lower metal fitting 30 are connected and fixed by welding or the like. Welding is performed using the upper side of the vertical piece 35a of the angular support plate 35 of the lower hardware 30.

As a result of the above, the base hardware IO and the lower hardware 30 are integrated, and support the upper hardware 20 so that its hook portion 20b can be slid relative to the upper hardware 20. In short, the upper portions of the wall panels, which are relatively upper and lower layers, are slidably supported by the upper hardware 20, and the lower layer of the wall panels is immovably fixed. Therefore, if an earthquake causes a displacement between the floors above and below the building, the upper part of the wall panel will slide to absorb the displacement, and within the allowable range, no abnormal stress will be applied to the wall panel itself. In other words, it functions as a curtain wall.

In addition, since the installation and removal of each of the metal fittings, positioning work such as height level, etc. can be easily performed from one direction by operating each bolt, construction work can be performed easily and accurately.

In the above embodiment, the specified amount of the accommodation gap 3θa of the hooking part 20b of the upper hardware 20, which is formed by the base vertical piece 10b of the base hardware 1O and the back plate 32 of the lower hardware 30, is as follows:
The above-mentioned accommodation gap 38a is obtained by the stop flange 14 portion integrally provided on the base vertical piece 10b, but is not necessarily limited to this configuration. Since it is sufficient to stop the movement, appropriate means can be adopted, such as providing the stopper on the back plate 32 side, or forming a pin-shaped protrusion as a stopper.

(Effects of the Invention) As described above in detail, according to the present invention, the lower metal fittings can bear the load of the wall panel and also have the function of supporting the upper metal fittings, so the number of parts is small. It is possible to reduce installation labor and improve workability.

In addition, positioning settings such as entry/exit and height level of each wall panel can be easily and accurately performed by working from one direction. This means that the surface level between adjacent wall panels, joint accuracy, etc. can be easily and beautifully finished when looking at the building as a whole, and metal fittings that contribute to excellent functionality and design effects. can be provided as.
