Description

The present invention relates to a mounting member for mounting a wall panel to a base hardware fixed to a building frame of a building, a wall panel mounting structure, a building, and a wall panel mounting method.

As a mounting structure for an ALC panel, a mounting structure as shown in FIG. 19 (lightweight aerated concrete panel mounting structure (conventional structure) 50) is widely adopted. In this mounting structure, an embedded anchor 52 embedded inside the ALC panel 51 and a panel joint surface of a lightning plate 53 used as a mounting fitting are joined by anchor bolts 54. On the other hand, between the above-mentioned panel joining surface of the lightning plate 53 and the other surface formed so that a step is created by the two-step bending process, and the back surface of the ALC panel, a connection is made to the building frame 55. A base hardware 56 having an L-shaped cross section is fixed in a sandwiched manner (Patent Document 1).

Regarding embedding anchors in ALC panels, it is possible to bury them in advance during the panel manufacturing process, but it is also possible to drill holes and bury them using an electric drill commonly used at the construction site. Often.

In the case of manual work on site, if there is an error in the buried position of the embedded anchor of the ALC panel, it may be difficult to attach the ALC panel. If such errors can be absorbed by the mounting hardware, construction defects in wall structures using ALC panels can be reduced and construction speed can be improved. For this reason, there is a need for a mounting bracket that can absorb errors in the embedded position of the embedded anchor.

The mounting bracket that can meet these demands consists of a combination of two metal fittings, a main plate and an auxiliary plate, each having a specific shape. A mounting hardware (mounting hardware) has been proposed that has a structure including a protrusion extending in the same direction and at the same height with respect to the surface of a flat plate part (see Patent Document 2).

According to the mounting hardware disclosed in Patent Document 2, the error in the buried position of the embedded anchor can be absorbed by the mounting hardware without changing the positional relationship between the ALC panel and the building frame, and the installation work of the panel can be improved. The above errors can be eliminated in stages.

Japanese Patent Application Publication No. 2015-232219 Patent No. 6405591

A washer is sometimes placed between the mounting bracket and the panel, but these mounting brackets and the washer are separate members, which requires time and effort to assemble the mounting bracket and washer on site. For example, if you let go of your hand for some reason during installation, the washer may fall. Therefore, the washer must always be held down by hand, which hinders the improvement of work efficiency.

Further, in the mounting hardware described in Patent Document 2, the main body plate and the auxiliary plate (washer) are integrated at the factory, but cannot be removed at the construction site. Therefore, for example, when the thickness of the base hardware is different, it is necessary to prepare multiple types of mounting hardware that match the thickness of the base metal. Another problem was that it required a large number of hardware such as pins for integrating the main plate and the auxiliary plate, resulting in high costs.

The present invention has been proposed in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a mounting member and a wall panel that prevent the washer from falling during installation work and improve workability. Our objective is to provide installation methods for mounting structures, buildings, and wall panels.

Embodiments of the present invention will be described below with reference to the drawings.
[First embodiment]
The attachment member of the present invention is a wall panel attachment member that attaches the wall panel to base hardware fixed to the building frame of a building.
The mounting member of the present invention includes a mounting bracket and a washer disposed between the mounting bracket and the wall panel.

<Mounting bracket>
FIG. 1 is a perspective view showing an example of the configuration of a mounting bracket according to the present invention, in which (a) is a perspective view and (b) is a side view. FIG. 2 is a diagram illustrating how the mounting bracket is butted against the underlying hardware. FIG. 3 is a diagram illustrating a method of manufacturing the mounting fitting.

The mounting bracket 1 is a mounting bracket for attaching a wall panel (panel 20) to a base hardware 32 fixed to a building frame on a building wall, particularly an exterior wall, and is made of a bent metal plate. In this embodiment, the mounting fitting 1 is formed by bending a substantially rectangular (in the example shown in FIG. 3, a substantially rectangular) metal plate.

At both ends of the metal plate in a first direction (short side direction in the figure) parallel to one side of the metal plate, at least one end in a second direction (long side direction in the figure) perpendicular to the first direction. A pair of first protruding pieces 3 whose portions are bent substantially perpendicularly on the same side with respect to one main surface of a metal plate; and a substantially flat main body 2 disposed between the pair of first protruding pieces 3. and a protrusion that protrudes from the main body 2 in a direction opposite to the bending direction of the first protrusion piece 3. The protruding portion is provided with a locking means that allows the mounting bracket 1 to be attached to the base hardware 32 at a substantially right angle.

In the example shown in FIG. 1, the protrusions include a pair of first protrusions in which a part of the metal plate is cut into a tongue shape, and the tongue-shaped portion is bent in the opposite direction to the bending direction of the first protrusion piece 3. It has two protruding pieces 4.

In the example shown in FIG. 3, a substantially rectangular metal plate is used, but a substantially square metal plate may be used. In the following description, the first direction will be referred to as the "short side direction" and the second direction will be referred to as the "long side direction." However, the present invention is not limited thereto, and the first direction may be the long side direction of the metal plate, and the second direction may be the short side direction of the metal plate.
In the examples shown in FIGS. 1 to 3, the "long side direction" of the metal plate coincides with the "longitudinal direction" of the mounting fitting, but the invention is not limited to this.

The pair of first protruding pieces 3 are formed by bending at least a portion of the long side of the metal plate substantially perpendicularly on the same side with respect to one main surface of the metal plate at both ends of the metal plate in the short side direction.
By having the first protruding pieces 3 bent on both sides, the mounting fitting 1 can ensure sufficient strength even if the thickness of the metal plate is relatively thin.

In the example shown in FIG. 1, each of the pair of first protruding pieces 3 is bent over the entire length in the long side direction of the metal plate, but the invention is not limited to this. Only a part of it may be bent. Further, the first protruding piece 3 may be formed not only at one location but at multiple locations along the long side direction of the metal plate.

The height (t1) of the first protruding piece 3 is not particularly limited, but is, for example, 10 mm to 15 mm from the viewpoint of strength and ease of processing during manufacturing.

The pair of second protruding pieces 4 are formed by cutting a portion of the metal plate into a tongue shape, and bending the tongue-shaped portion in a direction opposite to the bending direction of the first protruding piece 3 with respect to one main surface of the metal plate. It will be done.

In the mounting bracket 1 shown in FIG. 1, the first protruding piece 3 and the second protruding piece 4, which are arranged on the same side in the short side direction of the metal plate, are substantially on the same plane. Since the first protruding piece 3 and the second protruding piece 4 are on substantially the same plane, manufacturing by bending a metal plate is easy, and sufficient strength can be ensured.

In addition, in the mounting fitting 1 shown in FIG. 1, the pair of second protruding pieces 4 are located at approximately the same distance from the end on the side that contacts the underlying hardware 32 in the longitudinal direction of the main body 2. Since the pair of second protruding pieces 4 are located at approximately the same distance from the longitudinal end of the main body 2, the mounting bracket 1 is attached to the base hardware 32 having an L-shaped cross section, as shown in FIG. At this time, by bringing the side portions of the pair of second projecting pieces 4 into contact with the end portions of the base hardware 32, the mounting bracket 1 can be easily and reliably positioned approximately at right angles to the base hardware 32. , a certain length can be secured as an allowance for hanging onto the base hardware 32 (see FIG. 9).

The distance (l) of the second protruding piece 4 from the longitudinal end of the main body 2 depends on the amount of engagement with the metal base 32 (see FIGS. 2 and 9).

The height (t2) of the second protruding piece 4 is set to a level that does not exceed the thickness of the underlying hardware 32.
The width (w) of the second projecting piece 4 is not particularly limited as long as the above function can be ensured, but from the viewpoint of strength and ease of processing during manufacturing, it is, for example, 5 mm to 10 mm.

In this way, with this mounting bracket 1, in the wall panel installation method, the mounting bracket 1 can be easily and reliably attached to the base hardware 32 at a substantially right angle, and the mounting bracket 1 can be attached to the base hardware 32 easily and reliably. can be ensured at a constant level, and workability can be improved.

Among the bent metal plates, a substantially flat body portion 2 is formed between the pair of first protruding pieces 3, and the mounting bracket 1 is provided approximately at the center of the body portion 2. It has a long hole 5 through which a bolt 26 for fixing to the panel 20 is inserted.

As shown in FIGS. 9 and 11, which will be described later, the elongated hole 5 is sufficiently larger than the thickness of the bolt member (bolt 26) that is screwed into the anchor nut (O-nut 25) of the panel 20, and It is formed with a width smaller than the diameter of the head and a length preset at the design stage. By making the hole an elliptical hole (elongated hole 5) instead of a perfect circle, it is possible to absorb misalignment of the anchor nut of the panel 20.

The mounting bracket 1 may also have a slit 6 provided at one end of the main body 2 in the longitudinal direction. This slit 6 becomes a welding piece when the mounting bracket 1 is welded to the base hardware 32.

By providing the slit 6 at one end of the mounting bracket 1, it becomes possible to weld the mounting bracket 1 from one direction while ensuring a certain level of quality. As a result, for example, in the case of a horizontal wall construction method, welding can be performed without changing the welding posture, and in the case of a vertical wall construction method, the problem of the welding rod not being able to reach even behind the column is solved, It becomes possible to perform construction without going around.

The width of the slit 6 is at least a width into which a welding rod can be inserted, and is preferably 15 mm or more, for example.

The length of the slit 6 depends on the amount of engagement with the base hardware 32 (see FIGS. 9 and 10). If the slit 6 exceeds the base hardware 32, the cross section will be damaged and the strength will decrease, so the slit 6 should not go beyond the base metal 32. In the base hardware 32 of this embodiment, the engagement distance with the base hardware 32 is substantially equal to the distance (l) of the second projecting piece 4 from the longitudinal end of the main body 2 . That is, the depth of the slit 6 from the longitudinal end of the main body 2 does not exceed the distance (l) of the second protruding piece 4 from the longitudinal end of the main body 2.

Such a mounting bracket 1 can be manufactured by cutting and bending a metal plate (sheet metal).

For example, first, as shown in FIG. 3, a flat metal plate is prepared. Then, the first protruding piece 3 and the second protruding piece 4 are formed by cutting out the shaded portion in the figure to form a long hole 5 and a slit 6, and bending the dotted line portion. By cutting a part of the metal plate into a tongue shape as shown in FIG. 3, the first protruding piece 3 and the second protruding piece 4 can be formed in one bending operation. According to such a method, processing is easy and costs can be reduced. Of course, the first protruding piece 3 and the second protruding piece 4 may be formed in separate operations.

The thickness of the metal plate constituting the mounting bracket 1 is preferably 3.0 mm or more from the viewpoint of ease of processing and ensuring sufficient strength. However, it is not limited to this value.

In addition, in the above description, the case where the slit 6 (notch) is formed on one end side of the mounting bracket 1 was explained as an example, but the present invention is not limited to this. 6 may be omitted.

Further, in the above description, the case where only one slit 6 is formed is given as an example, but the present invention is not limited to this, and for example, two or more slits 6 may be formed. good.

<Washer>
FIG. 4 is a diagram showing an example of the configuration of a washer related to the wall panel mounting member of this embodiment, in which (a) is a perspective view, (b) is a top view, and (c) is a front view. Moreover, FIG. 5 is a figure which shows the state which combined the washer and the mounting bracket in this embodiment, (a) (b) is a perspective view, (c) is a front view. FIG. 6 is a diagram showing another configuration example of the washer according to the present embodiment.

In the example shown in FIG. 4, the washer 10 is formed by bending a substantially rectangular metal plate, and the two ends of the metal plate are bent substantially perpendicularly to one main surface of the metal plate on the same side. It has a pair of third protruding pieces 12 and a substantially flat washer body 11 disposed between the pair of third protruding pieces 12. In the example shown in FIG. 4, a pair of notches 13 are formed at one end of the washer body 11 in the short side direction.

The pair of third protruding pieces 12 has a narrow portion where the width between the pair of third protruding pieces 12 is narrow. In the example shown in FIG. 4, each of the pair of third protruding pieces 12 has a bent part 16 that is bent inwardly into a substantially dogleg shape when viewed from the side, The space between the portions 16 is a narrow portion. The dimension of the narrow portion, that is, the inner dimension between the pair of bent portions 16 is slightly narrower than the external dimension of the mounting bracket 1.

As shown in FIG. 5, the washer 10 is arranged along the side where the elongated hole 5 is formed, not the side where the slit 6 is formed, with respect to the pair of second protruding pieces 4 of the mounting bracket 1. Ru.
The washer 10 is arranged such that the pair of third protruding pieces 12 overlap the outer sides of the pair of first protruding pieces 3 of the mounting fitting 1, respectively. Thereby, the washer 10 can be placed with respect to the mounting bracket 1 without bending or shifting.

At this time, when the pair of third protruding pieces 12 of the washer 10 are arranged so as to overlap the outer sides of the pair of first protruding pieces 3 of the mounting bracket 1, the pair of bent portions 16 are arranged on the outside of the pair of first protruding pieces 3 of the mounting bracket 1. It contacts the outside of the first protrusion piece 3 and presses the first protrusion piece 3 from the outside. As a result, the mounting bracket 1 is sandwiched between the narrow portion of the washer 10.

As a result, even if the operator does not always hold the washer 10 against the mounting bracket 1 during the installation process, for example, even if the worker releases his/her hand during the installation process, the washer 10 will not fall from the mounting bracket 1. It can be prevented. As a result, work efficiency at the construction site can be improved.

Furthermore, since the mounting hardware and washer can be shipped in a pre-integrated state at the factory, there is no need to assemble them at the construction site, reducing labor. As a result, work efficiency at the construction site can be improved.

Furthermore, even if the base metal fittings 32 have different thicknesses, it is possible to handle base metal fittings 32 of various thicknesses by simply changing the washer 10 at the construction site, and the mounting bracket 1 and the washer 10 can be integrated. Since there is no need for parts such as pins, the number of hardware and costs can be reduced.

In addition, as shown in FIG. 6, the washer 10 may have a cut-out slit 17 in place of the closed hole 14 in the washer body 11. Due to the cut-out shape, for example, during installation, even if the mounting bracket 1 and washer 10 are overlapped and the bolt 26 is inserted into the bolt insertion hole (elongated hole 5 and slit 17), the bolt can be loosened. This allows the position of the washer 10 to be corrected.

Further, one or more convex portions 15 are provided on the surface of the washer body 11 that comes into contact with the mounting bracket 1, and the sum (t3) of the thickness of the washer body 11 and the height of the convex portions 15 is determined by the base hardware 32. It is preferable that the thickness be approximately equal to the thickness of .
As a result, the mounting bracket 1 is attached to the base hardware 30 such that the distance between the mounting bracket 1 (main body portion 2) and the panel 20 is constant, that is, the mounting bracket 1 (main body portion 2) is approximately parallel to the panel 20. can be fixed to.

The size, number, and arrangement of the convex portions 15 are not particularly limited, and may be one or two or more. In the example shown in FIG. 4, one washer is arranged on each side of the hole 14, but for example, three washers are arranged on each side of the hole 14, as in the case of a washer 10A (10) shown in FIG. 12, which will be described later. You can leave it there.

These convex portions 15 are formed, for example, by half punching. By forming the convex portion 15 by half punching the washer 10, the sum t3 of the heights of the convex portions 15 can be adjusted to be approximately equal to the thickness of the base metal fitting 32 even for base metal fittings 32 of different thicknesses. can. Thereby, for example, even if the thickness of the base hardware 32 differs depending on the part of the building, the panel can be attached by changing the washer 10 placed between it and the mounting bracket 1.
Further, for example, if only the thickness of the washer body 11 can be made substantially equal to the thickness of the underlying hardware 32, the convex portion 15 may not be formed.

<Wall panel installation method and mounting structure>
Next, a wall panel mounting method and a mounting structure using the above-described mounting members will be described. The wall panel (panel 20) is, for example, an exterior wall panel, but the present invention is not limited thereto.
In addition, although the following description exemplifies the case where a lightweight aerated concrete panel is used as a wall panel, the present invention is not limited to this.

The wall panel mounting method of the present invention can be carried out basically in the same manner as the conventional wall panel mounting method using the above-described mounting fittings 1 and washers 10.
The wall panel may be a vertical wall panel arranged so that the long side direction of the wall panel is substantially vertical, or a horizontal wall panel arranged so that the long side direction is substantially horizontal. good.
Basically, the mounting bracket 1 is attached to the panel so that the longitudinal direction of the mounting bracket 1 and the long side direction of the panel 20 match.

First, a wall panel (panel 20) that is attached to a building frame using mounting brackets will be described.
FIG. 7 is a partial cross-sectional view showing an example of the configuration of a wall panel. FIG. 8 is a perspective view showing an example of the structure of the locking metal fitting.
The panel 20 is not particularly limited, and although a lightweight cellular concrete panel is shown here as an example, it can also be applied to inorganic panels commonly used as architectural panels, such as cement-based extrusion panels. Further, the panel surface may be made of raw material or may be coated.

A long hole 21 is drilled in a direction substantially perpendicular from the edge surface to the edge surface of the panel 20, and a counterbore hole 22 is bored substantially perpendicularly from the surface of the panel 20 so as to communicate the surface of the panel 20 with the long hole 21. (See Figure 7).

A rod-shaped or tubular steel member 23 is inserted into the elongated hole 21 from the small end of the panel 20, and a locking fitting 24 is inserted into the counterbore hole 22 from the surface of the panel 20. Inside the panel 20, a steel material 23 and a locking fitting 24 are engaged.
As shown in FIG. 8, this locking metal fitting 24 is composed of an O-nut 25 having an engagement hole 25a, a bolt 26, and a washer 27. The steel material 23 is engaged with the engagement hole 25a of the O-nut 25 inside the panel 20.

A long hole 21 is bored in the face of the panel 20 in a direction substantially perpendicular to that face, and a counterbore hole 22 is opened from the surface of the panel 20 and reaches perpendicular to this face for communication. The long holes 21 and the counterbore holes 22 can be easily drilled with a hand-held electric drill commonly used at construction sites, but they can also be drilled in advance during the panel manufacturing process. Next, insert the O-nut 25 of the locking fitting 24 into the elongated hole 21 through the counterbore hole 22, with the engagement hole 25a of the O-nut 25 first, and insert the steel material 23 through the elongated hole 21 so that it passes through the engagement hole 25a. Attach. The O-nut 25 has a length that does not reach the outside of the counterbore hole 22.

The diameter of the engagement hole 25a of this O-nut 25 is approximately equal to the outer diameter of the steel material 23, and when the steel material 23 passes through the engagement hole 25a, the O-nut 25 and the steel material 23 are engaged and integrated. The steel material 23 can be passed through one panel 20 horizontally, for example, at a plurality of upper and lower positions, and the base metal fittings 32 can be fixed by attaching the locking metal fittings 24 vertically (in the longitudinal direction of the panel). can be increased.
Further, the O-nut 25 may be arranged and fixed by welding to reinforcing bars inside the panel 20 or the like. In that case, the steel material 23 and the engagement hole 25a may be omitted.

<Vertical wall construction method>
FIG. 9 is a perspective view showing a configuration example of a wall panel mounting structure (vertical wall construction method) of the present invention, and FIG. 10 is a sectional view.
The wall panel is a vertical wall panel arranged so that the long side direction of the wall panel is substantially perpendicular.

The wall panel mounting structure is a wall panel mounting structure using the above-mentioned mounting fittings 1, and the surface of the side from which the second protruding piece 4 protrudes is attached to the base hardware 32 on one end side of the main body portion 2. The mounting fittings 1 are disposed such that the pair of second protruding pieces 4 are in contact with each other, and the side portions of the second protruding pieces 4 are in contact with the base hardware 32, respectively.

Since the pair of second protruding pieces 4 of the mounting bracket 1 are located at approximately the same distance from the longitudinal end of the main body 2, the pair of second protruding pieces 4 can easily By abutting the side surface of 4 against the end of the base metal fitting 32, the mounting bracket 1 can be easily and reliably positioned approximately at right angles to the base metal fitting 32, even in places where the metal fitting is difficult to see directly. can do. In addition, by bringing the side surfaces of the pair of second protruding pieces 4 into contact with the ends of the base metal fittings 32, a constant length can be ensured without increasing or decreasing the amount of contact with the base metal fittings 32. can.
