Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a wall panel on a body, and more particularly to a mounting structure having improved seismic resistance.

[0002]

2. Description of the Related Art In recent years, there are many buildings in which wall surfaces are constructed by attaching wall panels such as lightweight cellular concrete (ALC) panels and cement-based panels to a steel frame structure. In such a building, a self-weight receiving metal fitting that supports the weight of the wall panel is attached to the body, the wall panel is supported by the self-weight receiving metal fitting, and a plate member that connects the body and the surface of the wall panel is provided. One end of the plate member is fixed to the body and the other end is fixed to the wall panel via bolts.

In a building having a steel frame structure, the horizontal relative displacements of the upper and lower beams are different when a horizontal force is applied due to an earthquake, so that the frame frame formed in a rectangular shape is deformed into a substantially parallelogram and the upper layer is formed. The inter-beam distance between the lower beam and the lower beam changes. Therefore, when the wall panel is rigidly attached to the body,
Shear force is generated in the in-plane direction of the panel mounting part, and if the allowable force is exceeded, the panel mounting part will be destroyed. For this reason, it is general that the wall panel is attached so as to be able to move relative to the deformation of the body frame so as to follow the deformation.

As described above, various proposals have been made as a mounting structure for flexibly joining the wall panel to the body (Japanese Patent Laid-Open No. 3-2.
No. 5138, No. 3-55337, No. 3-23514, No. 3-23518, No. 3-23519). Among them, the technique disclosed in Japanese Utility Model Laid-Open No. 3-23514 (specification attached to Japanese Patent Application No. 1-83800) has a larger diameter than the screw shaft portion and a predetermined length at the root portion of the head. Using a bolt having a spacer shaft part of, while fitting the spacer shaft part of this bolt into the long hole of the mounting plate whose one end is fixed to the body,
The present invention relates to a wall panel mounting structure that is configured to directly or indirectly abut on a skeleton by abutting an end of the spacer shaft portion against a stopper plate.

In the above technique, the mounting plate is allowed to move with respect to the wall panel even if the pillar and the wall panel are relatively displaced, so that even if an unreasonable force is applied to the wall panel, damage or durability is caused. And mounting reliability is not reduced.

[0006]

However, even the above-mentioned technique is not completely free of problems, and when an earthquake force acting on the skeleton acts in a direction perpendicular to the surface of the wall panel,
There is a problem that the wall panel may be destroyed. That is,
The force at the time of the earthquake acts as a bending force for the bolt, and as a result, a large force is applied to the edge part of the stopper plate,
There is a problem that the edge portion bites into the wall panel and the panel is broken.

Further, since the bolt has a special shape, it is difficult to manufacture, and the manufacturing cost increases. In particular, since the end surface of the spacer shaft portion is brought into contact with the stopper plate to apply the fastening force of the bolt, it is necessary to make the diameter of the spacer shaft portion sufficiently larger than the diameter of the screw shaft portion. As the diameter of the bolt increases, the diameter of the bolt head also inevitably increases. Therefore, the material cost and the processing cost increase, and the manufacturing cost increases.

It is an object of the present invention to provide a mounting structure in which the frame of a building is transformed into a substantially parallelogram during an earthquake and the wall panel is not destroyed even if the distance between the beams changes.

[0009]

In order to solve the above problems, a first wall panel mounting structure according to the present invention comprises a ruler member fixed to a beam to define a wall panel mounting position, and a longitudinal member. A mounting plate in which one side is welded to the ruler member and a long hole having a predetermined width and length is formed on the other side, a bolt hole fixed to a wall panel and facing an anchor nut provided on the wall panel, and the mounting. A reinforcing plate having a length projecting from the end of the surface of the plate in which the long hole is formed, a bolt member screwed to an anchor nut provided on the wall panel via the mounting plate and the reinforcing plate, and the reinforcing plate A cylindrical regulation member having an outer diameter larger than the bolt hole and an inner diameter larger than the screw diameter of the bolt member and longer than the thickness of the mounting plate, and the regulation member in the long hole of the mounting plate. It is characterized in that screwed into an anchor nut provided in the wall panel with passing the bolt member through.

The second wall panel mounting structure includes a ruler member fixed to the beam to define the wall panel mounting position, and C
A C-shaped metal object having a mold cross section and a leg portion straddling the ruler member so as to form a predetermined gap between the surface and the inner surface of the ruler member; and a wall panel vertically arranged. A washer plate fixed to the upper side and having a bolt hole facing an anchor nut provided on the upper side of the wall panel, one end of which is fitted in the space between the surface of the ruler member and the inner surface of the C-shaped metal object, and the other end of which is A fixed plate fixed to the washer plate via a bolt, and a long hole having a Z-shaped cross section composed of two parallel surfaces and having a predetermined width and length on one surface and the other surface. Has a mounting plate fixed to the ruler member and a bolt hole fixed to the lower side of the wall panel arranged in the vertical direction and facing the anchor nut provided on the lower side of the wall panel, and Projects beyond the end of the surface where the long hole is formed A reinforcing plate, a bolt member screwed into an anchor nut provided on the lower side of the wall panel via the mounting plate and the reinforcing plate, and an outer diameter and a bolt larger than the diameter of the bolt hole of the reinforcing plate. It is characterized in that it has an inner diameter larger than the screw diameter of the member and a length larger than the thickness of the mounting plate, and has a restricting member interposed between the elongated hole of the mounting plate and the bolt member.

In the mounting structure of the second wall panel,
The ruler member is composed of a member having an L-shaped cross section,
When a C-shaped metal object is laid over the upright piece of the ruler member, the tips of the legs of the C-shaped metal object arranged on the inner surface side of the upright piece are made to reach the vicinity of the piece orthogonal to the upright piece, and the C-shaped metal object It is preferable to weld the two sides of the leg portion and the ruler member.

In the above-mentioned mounting structure of each wall panel, the restricting member includes a collar portion that comes into contact with the head portion of the bolt member, and a neck portion whose length from the base portion to the tip of the collar portion is greater than the thickness of the mounting plate. It is preferable to configure.

[0013]

In the mounting structure of the first wall panel, the mounting plate having the long hole formed on the free end side is welded to the body of the building.
A reinforcing plate having a width larger than the width of the mounting plate on the wall panel, a length protruding from the end on the side where the long hole is formed, and a bolt hole is fixed so that the bolt hole faces the anchor nut of the wall panel. The bolt member is equipped with a cylindrical regulating member having an outer diameter smaller than the width of the elongated hole and larger than the diameter of the bolt hole and an inner diameter larger than the screw diameter of the bolt member and longer than the thickness of the mounting plate. To do.

When the elongated hole of the mounting plate and the bolt hole (anchor nut) of the reinforcing plate are opposed to each other and the bolt member is passed through the elongated hole and the bolt hole, the regulating member remains in the elongated hole. Therefore, by fastening the bolt member to the anchor nut, the wall panel has a degree of freedom of relative movement according to the size of the long hole formed in the mounting plate and the diameter of the regulating member in the direction parallel to the surface with respect to the body. . Therefore, when a horizontal force acts on the skeleton and the beam-to-beam distance changes, the wall panel moves relative to the skeleton with this change. Therefore, the wall panel is not subjected to the force associated with the change in the beam-to-beam distance, and the panel can be rotated.

Further, when the change in the distance between the beams of the frame acts as a force perpendicular to the surface of the wall panel, the edge of the mounting plate presses the surface of the reinforcing plate, and the force acting on the reinforcing plate at this time is , The entire area of the reinforcing plate is transmitted to the wall panel. Therefore, the wall panel is not locally subjected to a large force and is not destroyed.

In the second wall panel mounting structure, the C-shaped metal article is laid over the ruler member fixed to the beam to form a gap between the inner surface of the C-shaped metal article and the surface of the ruler member, On the upper side of the wall panel arranged corresponding to the lower floor, a bolt plate and a washer plate having protrusions in the vertical direction along both ends in the width direction are fixed, and a fixing plate is provided between the gap and the washer plate. Is installed and one end of the fixing plate is fitted in the gap and the other end is fixed to the washer plate through the bolt, so that the wall panel corresponding to the lower floor can be vertically moved relative to the frame. It can be mounted with a degree of freedom of relative movement in the horizontal direction within the range of the degree of freedom, the width of the gap and the width of the fixed plate.

That is, since the wall panel corresponding to the lower floor is attached by simply fitting one end of the fixing plate into the gap formed by the ruler member and the C-shaped metal object, the distance between the beams of the frame changes. In such a case, it moves vertically or horizontally relative to the body in the gap. Therefore, a large force does not act on the wall panel via the bolt, and the wall panel is not destroyed.

Further, since the wall panel arranged corresponding to the upper floor is attached to the skeleton in the same manner as the first attachment structure, the wall panel has a degree of freedom of relative movement with respect to the skeleton. Therefore, even if a horizontal force acts on the body, the wall panel does not move relative to the body and a large force does not act on the panel.

In the above-described second wall panel mounting structure, the washer plate and the reinforcing plate support the force applied to the bolt and the bolt member even when a force in the direction perpendicular to the surface acts on the wall panel. By doing so, no local force acts on the wall panel, and no destruction occurs.

In the second mounting structure, when the leg of the C-shaped metal article is welded to the ruler member, the welded leg acts as a rib of the ruler member, and the strength of the ruler member is increased. Can be improved. Therefore, it can be advantageously applied as a wall panel mounting structure in high-rise buildings.

In each of the above-mentioned mounting structures, the restricting member has a flange portion that comes into contact with the head portion of the bolt member, and a neck portion in which the length from the base portion to the tip of the collar portion is larger than the thickness of the mounting plate. When configured, the wall panel can be easily attached to the body.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wall panel mounting structure will be described below with reference to the drawings. 1 is a cross-sectional view illustrating the first mounting structure, FIG. 2 is a perspective development view illustrating the first mounting structure, and FIG.
Is a cross-sectional view illustrating the second mounting structure, FIG. 4 is a perspective view illustrating the second mounting structure, and FIG. 5 is a schematic perspective view illustrating the entire structure of the wall panel mounted on the body.

First, the first mounting structure is shown in FIGS.
Will be described more specifically. In the figure, the wall panel 1 is made of a lightweight aerated concrete (ALC) panel, a cement-based panel, an extruded hollow panel, or the like. In this embodiment, the ALC panel is targeted. Anchor nuts 2 are provided at predetermined positions of the wall panel 1, for example, at two positions on both ends in the longitudinal direction and at the center of the wall panel 1 or four positions on both ends in the width direction.

A reinforcing plate 3 is fixed to the surface of the wall panel 1 at a position corresponding to the anchor nut 2.
The reinforcing plate 3 has a function to disperse a force in a direction perpendicular to the surface of the panel 1 against the wall panel 1 from a mounting plate 4 which will be described later as the body is displaced. For this reason, the reinforcing plate 3 is made of a steel plate having a length sufficient to project from the end portion of the plate 4 in the longitudinal direction when the mounting plate 4 is mounted, and having a predetermined strength and rigidity.

At a predetermined position of the reinforcing plate 3, a bolt hole 3a having a diameter slightly larger than the diameter of the bolt member 5 screwed into the anchor nut 2 and the reinforcing plate 3 are fixed to the wall panel 1. A hole 3b for inserting a joining member 6 such as a concrete nail or a concrete screw is formed. Therefore, it is possible to set the fixing position of the reinforcing plate 3 to the wall panel 1 by inserting a bolt that can be screwed into the anchor nut 2 into the bolt hole 3a and screwing it into the anchor nut 2. It is possible to insert the joining member 6 into the hole 3b and fix the reinforcing plate 3 to the wall panel 1.

A ruler angle 8 which serves as a reference when the wall panel 1 is attached is welded to the beam 7 which is the skeleton of the building. The ruler angle 8 is made of an angle material (angle steel), and one flange 8a is fixed to the beam 7 by means such as welding so that the other flange serves as a standing piece 8b and serves as a mounting reference for the wall panel 1. is doing. Also, ruler angle 8
A self-weight receiving metal fitting (not shown) is attached to the wall panel 1. By mounting the wall panel 1 on the self-weight receiving metal fitting, the weight of the panel 1 is supported by the frame.

The mounting plate 4 is formed in a Z-shape having two pieces arranged in parallel, and the long hole 4 is formed in one piece.
a is formed, and the other piece is formed as a welding piece 4b to be welded to the ruler angle 8. The long hole 4a has a width that is sufficiently larger than the thickness of the bolt member 5 screwed into the anchor nut 2 of the wall panel 1 and smaller than the diameter of the head of the bolt member 5, and is set in advance at the design stage. It has a long length.

The bolt member 5 is attached to the anchor nut 2 of the wall panel 1 by penetrating the elongated hole 4a of the mounting plate 4 and the bolt hole 3a of the reinforcing plate 3 with the cylindrical spacer collar 9 serving as a restricting member attached. By screwing, the wall panel 1 is attached to the body via the attachment plate 4.

The outer diameter of the spacer collar 9 is larger than the diameter of the bolt hole 3a of the reinforcing plate 3 and smaller than the width of the long hole 4a of the mounting plate 4, and the inner diameter thereof is slightly larger than the screw diameter of the bolt member 5. , Mounting plate 4 is even longer
Is formed into a cylindrical shape having a size slightly larger than the thickness of the.

Therefore, the bolt member 5 fitted with the washer 10 and the spacer collar 9 is attached to the long hole 4a of the mounting plate 4.
When the bolt is penetrated and screwed into the anchor nut 2, the fastening force of the bolt member 5 is transmitted to the reinforcing plate 3 via the spacer collar 9. At this time, a high surface pressure acts on the contact portion between the reinforcing plate 3 and the spacer collar 9, but this surface pressure is distributed to the entire area of the reinforcing plate 3 and transmitted to the wall panel 1. Therefore, a large contact pressure does not act on the local portion of the wall panel 1, and there is no risk of partial destruction.

Further, since the length of the spacer collar 9 is slightly larger than the thickness of the mounting plate 4, the mounting plate 4 is accompanied by the fastening of the bolt member 5 to the anchor nut 2.
There is no more force than necessary. Therefore, the mounting plate 4 and the wall panel 1 have a degree of freedom of movement relative to each other.

When the skeleton is displaced in a direction parallel to the surface of the wall panel 1 due to the horizontal force caused by the earthquake and the linear distance between the beam to which the lower end side of the wall panel 1 is attached and the beam to which the upper end side thereof is attached changes, The mounting plate 4 fixed to the beam 7 via the ruler angle 8 moves in the vertical direction according to the displacement of the frame. Therefore, if the amount of change in the beam-to-beam distance is within the range of the length of the long hole 4a, the skeleton moves up and down relative to the wall panel 1, and no force is exerted on the wall panel 1.

When the frame is displaced in the direction perpendicular to the surface of the wall panel 1, the mounting plate 4 is moved in accordance with this displacement.
Therefore, a large force locally acts on the reinforcing plate 3. However, the force is supported by the reinforcing plate 3, distributed over the entire area of the plate 3, and acts on the wall panel 1 as a contact surface pressure. Therefore, the local pressure contact force does not act on the wall panel 1.

Next, the procedure for attaching the wall panel 1 to the body will be described. First, the reinforcing plate 3 is fixed to the wall panel 1, and the wall panel 1 is arranged in a frame and placed on a weight receiving metal fitting (not shown). After arranging the wall panels 1,
Align the bolt holes 3a of the reinforcing plate 3 with the long holes 4a of the mounting plate 4, and attach the washer 1 to the bolt member 5.
0, the spacer collar 9 is attached, the long hole 4a and the bolt hole 3a are penetrated, and it fastens to the anchor nut 2. Thereafter, the mounting plate 4 is welded to the ruler angle 8 so that the wall panel 1 is mounted with a degree of freedom of relative movement with respect to the body.

Next, the second mounting structure will be described with reference to FIGS.
Will be described. The mounting structure shown in the figure is such that the upper floor of the wall panel 1 (hereinafter referred to as "wall panel 1b") corresponding to the lower floor and the upper-floor wall panel 1 (hereinafter referred to as "wall panel 1a") It is used when attaching the lower end side of. In the drawings, the same parts and parts having the same functions as those of the first mounting structure described above are designated by the same reference numerals, and the description thereof will be omitted.

The wall panel 1a has a structure substantially similar to the first mounting structure and is mounted on the body. However, in this structure, the spacer collar 11, which serves as the regulating member, is configured by integrating the collar 11a having a function as a washer and the neck portion 11b having a function as a spacer.
Therefore, as compared with the case where the spacer collar 9 and the washer 10 are configured as different members, the wall panel 1 (1a) can be easily mounted. This spacer collar 11 is the first
It is also possible to apply to the mounting structure of.

The reinforcing plate 3 can be the same as the first mounting structure. However, it is also possible to use the washer plate 12 described later in common. In this embodiment, the washer plate 12 is used as the reinforcing plate 3.

The washer plate 12 has the same shape as the reinforcing plate 3 and is fixed to the panel 1b corresponding to an anchor nut (not shown) provided on the upper end side of the wall panel 1b. That is, a bolt hole 12a and a hole 12b for inserting the joining member 6 are formed at predetermined positions of the washer plate 12, and projections 12c for preventing rotation of the fixing plate 13 described later are provided at both ends in the width direction over the entire length in the longitudinal direction. Are formed. The washer plate 12 is fixed to the wall panel 1b in the same manner as the reinforcing plate 3.

A C-shaped metal piece 14 is attached to the ruler angle 8 in a straddled state. C type hardware 14 is reinforcing plate 3
And a flat portion 14a having a width substantially equal to the width of
It has two leg portions 14b which are erected at right angles from both ends of a, and the erected pieces 8b of the ruler angle 8 are provided at predetermined positions of the leg portions 14b.
A groove 14c for fitting with is formed. When the C-shaped metal piece 14 is attached to the ruler angle 8 through the groove 14c, a gap 15 having a preset size is formed between the upright piece 8b of the angle 8 and the flat surface portion 14a.

The height dimension of the C type metal fitting 14 is a ruler angle 8
Is formed to be equal to or slightly smaller than the inner dimension (the width of the upright piece 8b minus the thickness of the flange 8a). Therefore, when the C-shaped metal article 14 is laid over the ruler angle 8, the free end side of the leg portion 14b reaches the flange 8a along the standing piece 8b. Therefore, the leg portion 14b and the standing piece 8
By welding b and the flange 8a, it is possible to make the leg portion 14b function as a rib of the ruler angle 8 and improve the strength of the ruler angle 8. Further, when the leg portion 14b is extended from the flange 8a and can be welded to the beam 7, the strength can be further improved.

As described above, the ruler angle 8 and the C-shaped hardware 14
When the strength of the angle 8 is improved by integrating the above, it becomes possible to apply it as a wall panel mounting structure in a high-rise building. In this embodiment, the height of the leg 14b on the free end side is larger than the height of the flat portion 14a.

The upper end side of the wall panel 1b is connected to the body through a fixing plate 13. The fixing plate 13 has a bolt hole 13a through which the bolt 16 is inserted. The fixed plate 13 has a thickness substantially equal to the gap 15 formed by the ruler angle 8 and the C-shaped metal piece 14, and the wall panel 1
When attached to b, the end portion is formed into a flat plate shape having a length that allows it to project from the upper end surface of the wall panel 1b and reach the upper end side of the standing piece 8b of the ruler angle 8.

Therefore, the bolt 16 is inserted into the fixing plate 13, the bolt 16 is passed through the bolt hole 12a of the washer plate 12 fixed to the upper end side of the wall panel 1b, and is screwed into the anchor nut. 13 is attached to the wall panel 1b, and the free end of the fixed plate 13 is a gap.
The wall panel 1b is attached to the skeleton by fitting with the wall panel 15.

In the above structure, the spacer collar
When the bolt 11 is attached to the bolt member 5, it is possible to prevent the bolt 16 from loosening by interposing a spring washer 17 therebetween. Then, the collar portion 11a and the neck portion 11b of the spacer collar 11 are spot-welded and integrated,
By storing this welded part in the long hole 4a of the mounting plate 4, the welded part does not rotate beyond the range in which it contacts the inner wall of the long hole 4a, and therefore the bolt 16 can be prevented from loosening. . Also, fix the fixed plate 13 to the washer plate.
Also when mounting to 12, it is preferable to interpose a flat washer 18 and a spring washer with the bolt 16.

In the second mounting structure constructed as described above, since the lower end side of the wall panel 1a has the same structure as the first mounting structure and is mounted on the skeleton, the linear distance between the upper and lower beams 7 is reduced. Even if it changes, this change can be absorbed by the relative movement of the mounting plate 4 and the bolt member 5, and a vertical force acts on the wall panel 1a according to the displacement of the skeleton. However, this force is distributed over the entire area of the plate 3 by the reinforcing plate 3 so that a large pressure contact force does not act locally.

The upper end of the wall panel 1b is attached to the frame by fitting the fixing plate 13 into the gap 15 formed by the ruler angle 8 and the C-shaped metal piece 14.
Therefore, the fixing plate 13 has the freedom of relative movement in the vertical and horizontal directions with respect to the body within the gap 15. Therefore, when a displacement parallel to the surface of the wall panel 1b occurs in the frame and the distance between the beams 7 changes, C changes in accordance with this change.
Since the metal mold 14 moves in the vertical direction with respect to the fixed plate 12, no force is exerted on the wall panel 1b.

However, since the fixed plate 13 is fitted in the gap 15, the leg portion 14b of the C-shaped metal piece 14 comes into contact with the side surface of the fixed plate 13 to rotate the plate 13 about the bolt 16. Sometimes. In this case, the corner of the bolt hole 13a side or the side surface corresponding to the washer plate 12 comes into contact with the projection 12c of the plate 12 to prevent the fixed plate 13 from rotating.

Further, the body is displaced in the direction perpendicular to the surface of the wall panel 1b, and in particular, a flat surface portion with respect to the fixed plate 12 is formed.
When a force that presses the wall panel 1b from 14a is applied, this force is transmitted to the washer plate 13 and distributed over the entire area, and a large local force does not act on the wall panel 1b.

A wall surface structure adopting the second mounting structure will be described with reference to FIG. In the figure, the wall panel 1 corresponding to the lowermost layer is placed and supported by an angle-shaped weight receiving metal fitting 19, and one side of the Z-shaped metal piece 20 is provided at the lower end side by a bolt. It is fastened to the anchor nut and is fixed to the frame by welding the other side of the Z-shaped metal object 20 to the self-weight metal object 17. Further, the wall panels 1a and 1b corresponding to the second and higher layers are self-weight receiving metal fittings attached to a ruler angle 8 fixed to a beam 7 forming each layer.
It is placed and supported on 21.

Then, the upper end side of the wall panel 1 and the lower end side of the wall panel 1b corresponding to the second level, and the upper end side of the wall panel 1b corresponding to the second level and the wall panel 1 corresponding to the third level.
The lower end side of a is attached to the body using the second attachment structure.

In the above wall structure, the leg portion 14b of the C-shaped hardware 14 is used.
Is welded to the flange 8a and the upright piece 8b while being straddled over the ruler angle 8, so that there are many ribs on the ruler angle 8 and the ruler whose strength is improved without providing a special member. It is possible to configure the angle 8.

That is, the force when the wind pressure acts on the wall panel 1 is applied from the reinforcing plate 3 to the ruler angle 8 via the mounting plate 4 and from the washer plate 12 to the fixed plate 13.
Is transmitted to the upright piece 8b of the ruler angle 8 via the, and a bending load is locally applied to the upright piece 8b. Therefore, by welding the leg portion 14b of the C-shaped metal article 14 to the ruler angle 8, it is possible to improve the strength against bending and reasonably support the acting bending load.

[0053]

As described in detail above, in the first mounting structure according to the present invention, the wall panel has one end having a degree of freedom of movement in the direction of the long hole formed in the mounting plate in the mounting plate. Can be attached. For this reason, when the skeleton is displaced, the skeleton moves with respect to the wall panel, and the force associated with the displacement does not act on the wall panel. In addition, since the reinforcing plate protrudes beyond the end of the mounting plate, even if a force in the direction perpendicular to the surface of the wall panel acts through the mounting plate, this force is distributed over the entire area of the reinforcing plate and is localized. No large force is applied to. Therefore, the destruction of the wall panel can be prevented. Further, even if an operator accidentally over tightens the bolt beyond the reference value, the mobility of the mounting plate is not impaired.

In the second mounting structure, the upper end side of the wall panel corresponding to the lower floor and the lower end side of the wall panel corresponding to the upper floor can be mounted with the skeleton with freedom of movement. Therefore, in the same manner as described above, no force acts on the wall panel in the direction parallel to the surface and in the direction perpendicular to the surface, and the destruction can be prevented.

Further, in the second mounting structure, when the leg portion of the C-shaped metal article is laid on the ruler member and welded to the member, the leg portion functions as a rib of the ruler member. Then
The strength of the ruler member can be improved.

Further, when the regulating member is constituted by the collar portion and the neck portion, it has a feature that the wall panel can be easily mounted.
