Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a wall panel for construction, which comprises a veranda portion, a parapet portion, a waist wall portion in a continuous window opening, and the like, in which the upper portion of the wall panel is pushed upward. The present invention relates to a method for obtaining surface accuracy of wall panels.

[0002]

2. Description of the Related Art With a building wall panel, when a wall surface is constructed by bouncing the upper part of the wall panel upward, a gap between adjacent wall panels often occurs and the surface accuracy is often poor.
In that case, it is necessary to correct the displacement of the wall panel.

A first conventional example in which the displacement of the wall panel is assembled will be described with reference to FIG. This method uses adjacent wall panels 5
If there is a deviation from each other, the attachment plates 52 are attached to both sides or one side of the abutting ends of the adjacent wall panels 51, and the vise 53 is tightened to correct the deviation to obtain surface accuracy. Round groove processing part 54 on the long side of the panel 51
Then, the joint mortar 55 is filled, and after the mortar is hardened,
The vise 53 and the attachment plate 52 are removed.

A second conventional example disclosed in Japanese Patent Laid-Open No. 6-307049 is shown in FIG. In this method, the wall panel 51 is attached by inserting the round bar 57 into the through hole 56a of the upper horizontal member 56, inserting the round bar 57 into the upper portion of the wall panel 51, and welding the through hole 56a. Reference numeral 58 is a flat bar which is arranged in the vertical panel joint 51a between the adjacent wall panels 51 and has an L-shaped metal fitting 58a fixed to the upper end thereof.

FIG. 7 shows a third conventional example disclosed in Japanese Unexamined Patent Publication No. 9-170271. This method is to correct the misalignment of the wall panel 51 by fitting a round pipe 59 into the round groove processing portion 54 formed on the long side surface of the wall panel 51.

FIG. 8 shows a fourth conventional example disclosed in Japanese Patent Laid-Open No. 10-8546. This method is intended to correct the misalignment of the wall panel 51 by sandwiching the U-shaped metal piece 60 in the upper portion of the wall panel joint 51a. 6
1 is a horizontal beam to which the wall panel 51 is attached, 62 is a ruler angle that abuts the inner surface of the wall panel 51, 6
Reference numeral 3 is a receiving angle for supporting the weight of the wall panel 51, and 64 is a lightning plate for attaching the wall panel 51 to the ruler steel material 62.

[0007]

In the above-mentioned first conventional example, since the mortar is used to fix the adjacent wall panels 51, the vise 53 cannot be removed until the mortar is hardened. In order for the mortar to harden,
Since a considerable amount of time is spent, there has been a problem that the vise 53 and the attachment plate 52, which are correction tools, have to be removed again one day. In addition, vise 53
However, it is a heavy burden to prepare so that there is no shortage, and if the surface of the support plate 52 becomes uneven due to the adhesion of mortar, it can be reused. There was also a problem that cleaning work was required because of this.

Next, in the second conventional example, the upper horizontal member 5
6 is fixed to the wall panel 51 only by the round bar 57, and the round bar 57 is welded and fixed to the upper horizontal member 56 at only one point of the through hole 56a. However, there is a problem that the out-of-plane restraint force is small and it is easily deformed. Particularly, when the deviation between the adjacent wall panels 51 is large, the vertical piece 56b is separated from the inner side surface of the wall panel 51,
The misalignment between the adjacent wall panels 51 could not be corrected. In addition, when the round bar 57 is driven into the upper edge surface of the wall panel 51, if it is driven in a curved manner due to the poor precision of the site work, the out-of-plane restraining force becomes small, and it may change over time. , Adjacent wall panels 51
There was also the problem that the mutual deviations of the two would gradually become apparent.

Further, in the third conventional example, the wall panel 51 is used.
Since the misalignment is corrected by using the round groove processing portion 54 of the wall panel 5, the wall panel 5 is adjusted depending on the accuracy of the round groove processing 54 between the wall panels 51.
There is a problem that the shift of 1 depends on the wall panel 51.
When the mutual circular groove processing 54 is processed with high accuracy, the misalignment of the wall panel 51 can be corrected without any problem, but when the error is particularly large, the wall panel 51 is completely absent.
I couldn't fix the gap. Although the round groove processing 54 of the wall panel 51 is performed in advance in a factory or the like, if the wall panel 51 has a warp, the accuracy of the round groove processing 54 is also improved.
According to the first conventional example, the wall panel 51 tends to warp and the adjacent wall panels 51 are more likely to be displaced. In many cases, the technology cannot effectively correct the displacement of the wall panel 51.

In the fourth conventional example, although the technique for correcting the displacement of the wall panel 51 is an effective technique, the collar portion 60a of the U-shaped metal piece 60 attached to the above-ground portion between the wall panels 51 is Since it comes out on the vertical surface of the outer surface of the upper part of the wall panel 51, it is possible to cover the brim portion 60a with the head tree when the head board is mounted on the wall panel 51. For example, when the sash is stored on the 51, the brim portion 60a is exposed below the drainer provided at the lower portion of the sash, and thus there is a problem in that the appearance is unsightly and unusable.

An object of the present invention is to provide a mounting structure for a wall panel and a surface precision adjusting method capable of solving the problems of the conventional methods as described above.

[0012]

According to a first aspect of the present invention, there is provided a wall panel fixed at two points: a ruler steel material installed on an upper flange of a horizontal beam and a receiving steel material attached to a lower part of the wall panel. And a horizontal member having a substantially L-shaped cross section having a substantially flat surface portion that abuts or approaches the upper edge surface and a brim portion that abuts the inner surface of the wall panel adjacent to the upper portion of the wall panel. It is attached to the upper end of the wall panel in the longitudinal direction so as to straddle the vertical joints of the wall panel, and the upper edge face in the vicinity of each vertical joint of the adjacent wall panel has a plate-like base end at the upper end. A wall panel mounting structure is characterized in that a member is driven in and the plate-shaped base end portion is welded and fixed to a substantially flat surface portion of the horizontal member having a substantially L-shaped cross section.

According to the invention of claim 1, since it is configured as described above, when the wall panels are warped or the like and the adjacent wall panels are displaced from each other, the brim portion of the horizontal member having a substantially L-shaped cross section is Since it is fixed to the plate-shaped base end portion of the rod-shaped member, which is abutted against the inner side surface of the wall panel and is driven into the upper edge surfaces of the wall panels which are close to the vertical joints, unlike the second conventional example,
It is possible to reliably weld and fix the plate-shaped base end portion of the rod-shaped member to the horizontal member having a substantially L-shaped cross section with a predetermined length dimension, and the rod-shaped portion of the rod-shaped member and the horizontal member having a substantially L-shaped cross-section. The brim portion of the wall can be firmly held at a predetermined interval, so that the misalignment of the adjacent wall panels can be corrected and corrected, and the misalignment of the adjacent wall panels becomes apparent due to aging. It is possible to avoid causing the problem of the second conventional example of being changed. The plate-shaped base end portion of the rod-shaped member is welded and fixed to the horizontal member having a substantially L-shaped cross section with a predetermined length dimension, and the predetermined dimension is 3 cm or more. This is preferable from the viewpoint that the rod-shaped portion and the brim portion of the horizontal member having a substantially L-shaped cross section are firmly held at a predetermined interval.

Further, in the invention of claim 1, unlike the second conventional example, a bar-shaped member having a plate-shaped base end portion is provided on the upper edge face of the adjacent two wall panels which are close to the vertical joint. Therefore, it is possible to reduce the distance between the two adjacent rod-shaped members provided on the two adjacent wall panels, and therefore, to correct the displacement between the two adjacent wall panels. The correction power of can be used particularly effectively. The position where the rod-shaped member is provided on the upper edge surface of the wall panel is preferably smaller than about 200 mm from the vertical joint, and it is particularly preferable that the position is close to 150 mm or less.

With the mounting structure according to the invention of claim 1, provisional fixing with a vise 53 can be carried out according to the invention of claim 5 described later, and the attachment plate 5 as in the first conventional example.
Since it can be performed on the brim portion of the horizontal member having a substantially L-shaped cross section instead of on the second portion, it is not necessary to prepare the attachment plate 52. The temporary fixing with the vise 53 is also only for a short time until the plate-shaped base end portion of the rod-shaped member is welded and fixed to the horizontal member having the substantially L-shaped cross section, and many vise 5 are used.
There is no need to prepare the 3 at all.

Further, the plate-shaped base end portion of the rod-shaped member has a substantially L-shaped cross section.
It is possible to perform welding and fixing to a character-shaped horizontal member in a state where it is held at any appropriate position. Therefore, as in the third conventional example, the accuracy of the round groove processing portion 54 and the like of the wall panel can be improved. It is possible to reliably correct the deviation between the two adjacent wall panels without depending on the dimensional accuracy.

Further, in comparison with the fourth conventional example, since the metal part such as the brim 60a is not exposed on the vertical surface part of the outer surface of the upper part of the wall panel, the sash is placed on the wall panel. In such a case, the metal part is not exposed below the drainer provided in the lower part of the sash, so that the appearance does not become unsightly.

In addition to the above, in the invention of claim 1, since the wall panels are connected to each other by the rod-shaped member having the plate-shaped base end portion at the upper end portion through the horizontal member having the substantially L-shaped cross section, For example, an out-of-plane force acting on the wall surface can be shared between two adjacent wall panels, and the load can be partially transmitted and shared between several adjacent wall panels. Can bear the load. That is,
The out-of-plane direction force is not concentrated and applied to only one wall panel, the force can be dispersed, and it is easy to provide a highly secure wall panel mounting structure. In addition,
In this case, if the length of the horizontal member having the substantially L-shaped section is set to have a long dimension that extends over several adjacent wall panels instead of a short dimension that extends over only two adjacent wall panels, the above description will be made. The function and effect described above become more reliable and can be said to be a preferable configuration.

[0019] Next, the invention as set forth in claim 2 is, in the wall panel mounting structure, between the vertical joints of the wall panels at least from the vicinity of the upper flange of the horizontal beam to the vicinity of the top of the wall panel. A flat bar is installed, the flat bar is directly or indirectly fixed to a horizontal beam, and the horizontal member having a substantially L-shaped cross section is fixed to the flat bar.

Since the invention of claim 2 is configured as described above, it has the following operational effect in addition to the operational effect of the configuration of the invention of claim 1.

First, two positions of two bar-shaped members, which are provided on two adjacent wall panels and are adjacent to the adjacent vertical joints, are located at two positions.
In addition to the location, the horizontal member having a substantially L-shaped cross section is also fixed to the flat bar indirectly fixed to the horizontal beam in the vicinity of the uppermost positions of the vertical joints of the wall panels, for a total of 3
Since the horizontal member having a substantially L-shaped cross section is fixed at a position, the correction force for correcting the displacement between the two adjacent wall panels is effectively applied, more than the invention of claim 1. Is possible.

To reiterate, the positions of the horizontal members having a substantially L-shaped cross section are constrained at the above-mentioned three positions in total, so that the wall panels are warped and the adjacent wall panels are displaced. Even in the case of a particularly large size, the brim portion of the horizontal member having a substantially L-shaped cross section can be continuously kept in contact with the vertical surface portions of the inner side surfaces of the two adjacent wall panels. In particular, in the structure of the second aspect of the present invention, since the horizontal member having a substantially L-shaped cross section is fixed at the position of the vertical joint position between the wall panels, which is the position where the displacement of the adjacent wall panels occurs, exactly. In addition, this is an effective technology in which the displacement between adjacent wall panels does not become apparent due to changes over time. At the position where the rod-shaped member is provided on the upper edge surface of the wall panel, the horizontal member having a substantially L-shaped cross-section is fixed even at the mutual vertical joint positions of the wall panel, so comparison with the invention of claim 1 Then, it is possible to set the position away from the vertical joint, and it may be about 300 mm or less from the vertical joint, and it is more preferable that the positions are close to each other by 200 mm or less.

According to the second aspect of the invention, the wall panel has two positions, that is, the position of the ruler steel material installed on the upper flange of the horizontal beam and the position of the receiving steel material installed on the lowermost part of the wall panel.
In addition to being fixed in place, it can also be fixed to the upper part of the wall panel by being attached directly or indirectly to a horizontal beam through a flat bar from a horizontal member having a substantially L-shaped cross section, It is possible to provide a wall panel mounting structure capable of withstanding a larger load against a wind load or a human load acting on the wall panel.

Explaining again, since the flat bar bears a part of the out-of-plane direction force applied to the wall panel, the out-of-plane direction force carried by the wall panel can be reduced, and the wall panel can be reduced. It is also advantageous in terms of design, and it is also possible to improve the productivity of the wall panel in the factory by reducing the amount of reinforcing bars and the like buried inside the wall panel.
In addition, in the mounting position of the wall panel, there are two positions, that is, the position of the ruler steel material installed on the upper flange of the horizontal beam and the position of the receiving steel material installed at the bottom of the wall panel. Compared to the configuration of the invention, the load acting on the mounting portion is also reduced, so a lighter mounting structure can be achieved.In some cases, using hook bolts, etc., the mounting portion can be mounted at the construction site. It is also possible to form it, and also in that aspect, it is not necessary to fix the metal fittings such as the embedded metal fittings to the reinforcing bars provided inside the wall panel in advance in the wall panel factory. It is possible to improve the productivity in the factory.

The effect of being able to bear the load on the entire wall surface described in the invention of claim 1 is that the structure of the invention of claim 2 ensures that the load is more reliably applied to several adjacent wall panels. It can be burdened. That is, since the horizontal member having a substantially L-shaped cross section is more firmly integrated and fixed to the wall panel than the structure of the invention of claim 1, the load transmission is further ensured, and thus the load is applied on the entire wall surface. The effect that can be paid becomes more certain.

According to a third aspect of the present invention, in the wall panel mounting structure according to the second aspect, in the horizontal member having a substantially L-shaped cross section, the wall panel has a vertical joint position in the thickness direction of the wall panel. Is provided with a slit-shaped hole or notch in a substantially flat portion at the central position of the flat bar, and the upper end of the flat bar is passed through the slit-shaped hole or notch, and the horizontal member has a substantially L-shaped cross section. And the flat bar is welded and fixed from above.

Since the invention of claim 3 is configured as described above, in addition to the effect of the invention of claim 1 or 2, the upper end portion of the flat bar has the cross section substantially L.
Since the horizontal member having a substantially L-shaped cross section and the flat bar can be welded and fixed from above by being passed through the slit-shaped hole or notch provided in the horizontal member having the L-shape,
It is possible to improve workability at the construction site with simple installation work. Also, since the welding work is downward welding, it is easy to ensure the welding quality, and it is easy to ensure the safety of the entire wall panel mounting structure regardless of the welding skill of the site worker. Become.

According to a fourth aspect of the present invention, in the wall panel mounting structure according to the above-mentioned second aspect, the wall panel is attached in the vicinity of the vertical joint position on the upper edge face of the wall panel or close to the wall panel in the thickness direction of the wall panel. A flat bar fixing portion having a slit-shaped hole or a notch for inserting the upper end portion of the flat bar at a central position of the flat bar, and the substantially L-shaped cross section provided at an end portion near the inner side surface of the wall panel. The flat bar and the horizontal member having a substantially L-shaped cross section are fixed to each other by a connecting member having a horizontal member fixing portion fixed to the horizontal member.

Since the invention of claim 4 is configured as described above, it has the same effect as the invention of claim 3, and in addition to the upper end portion of the flat bar and the cross section substantially L by the connecting metal fitting.
It can be configured by connecting with a horizontal member having a character shape. Therefore, as in the invention of claim 3, a slit-shaped hole or notch for inserting the upper end portion of the flat bar into the horizontal member having a substantially L-shaped cross section. Need not be formed, thus
As in a fourth embodiment (FIG. 4) described later, it is possible to use a general-purpose member such as an angle (angle steel) as the horizontal member having a substantially L-shaped cross section.

Further, since the upper end portion of the flat bar and the horizontal member having a substantially L-shaped section are connected by the connecting metal fitting, the width dimension of the substantially flat surface portion of the horizontal member having a substantially L-shaped section is reduced. Therefore, it is possible to reduce the weight of the entire member and improve the workability in the field.

According to a fifth aspect of the present invention, there is provided a step of providing the horizontal member having a substantially L-shaped cross-section over the inner side surfaces of the adjacent wall panels and near the upper edge of the wall panel, and the cross-section. After the step of tightening and temporarily fixing the substantially L-shaped horizontal members to the adjacent wall panels, at least the rod-shaped member, the upper end portion of the flat bar, or the connection is provided. This is a method for obtaining surface accuracy of a wall panel, which is characterized in that it is fixed to one of the metal fittings.

Since the invention of claim 5 is configured as described above, when a deviation occurs between adjacent panels, the cross section is substantially L.
It is possible to cover the upper ends of the adjacent wall panels with a horizontal member having a character shape and directly tighten the horizontal member having a substantially L-shaped cross section with a vise to easily correct the displacement and temporarily fix the member. . After that, the horizontal member having a substantially L-shaped cross section is welded to at least one of the rod-shaped member, the upper end portion of the flat bar, and the connecting fitting. Since the vise can be removed after welding, it is not necessary to prepare many vise as compared with the first conventional example. Further, since the horizontal member used for correcting the deviation is used as it is as the mounting metal object, it is not necessary to use the correction attachment plate required in the first conventional example, and the deviation between the adjacent wall panels can be efficiently performed. It is possible to correct the surface accuracy of each wall panel.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, as an example of a wall panel mounting structure according to the present invention, four embodiments of a wall panel mounting structure mounted on a veranda and a surface accuracy determining method will be described.

<First Embodiment> FIG. 1 relates to an embodiment of the present invention and is a perspective explanatory view of a wall panel and a perspective view of a dedicated metal object.

A cross section L is formed on the upper surface of the upper flange 1a of the horizontal beam 1.
A horizontal piece 2a of an elongated ruler angle 2 having a character shape is fixed, and a horizontal piece 3a of an angle piece 3 having an L-shaped cross section having a predetermined width is fixed to the lower surface of the lower flange 1b of the horizontal beam 1. .

At this time, the upright pieces 2b of the ruler angle 2 and the upright pieces 3b of the angle piece 3 are arranged in the same plane,
A mounting piece 4a of a vertical ground angle 4 having an L-shaped cross section and having a predetermined length is in surface contact with and abuts on both of the upright pieces 2b, 3b and is fixed by welding or the like, and the vertical ground angle 4 is arranged in the vertical direction. To be done.

At the lower end of the vertical base angle 4, a long receiving angle 5 having an L-shaped cross section is arranged parallel to the ruler angle 2 and fixed by welding or the like. 5a supports the lower end surface of the wall panel 6.

The surface of the upright piece 5b of the receiving angle 5 and the upright piece 2b of the ruler angle 2 on the wall panel 6 side are in the same plane as the surface of the mounting piece 4a of the vertical ground angle 4 on the horizontal beam 1 side. The rear surface (inner side surface) of the wall panel 6 is arranged at that position.

On the other hand, inside the wall panel 6, the wall panel 6 is provided at a height position corresponding to the ruler angle 2 installed on the upper flange 1a of the horizontal beam 1 and at a height position corresponding to the receiving angle 5. Anchor steel rods 7a, 7b are arranged in the width direction of the wall panel 6 and O bolts 8a, 8b engaged with the anchor steel rods 7a, 7b are provided so as to project from the back surface of the wall panel 6. The O bolts 8a and 8b are attached to the mounting bracket 9,
They are attached to the ruler angle 2 and the receiving angle 5 via nuts 10, respectively.

On the upper edge surface 6a of the panel 6, a horizontal member 11 having a substantially L-shaped cross section, which is composed of a substantially flat surface portion 11a and a brim portion 11b, is provided. 6a is arranged so that the brim portion 11b abuts on the inner side surface, and is driven into the upper edge surface 6a of the wall panel 6.
It is fixed by welding to a rod-shaped member 12 having a plate-shaped base end 12a at the upper end.

The horizontal member 11 having a substantially L-shaped cross section has a brim portion 11b which abuts on the inner side surface of the wall panel 6, and has a rod shape which is driven into the upper edge face 6a which is close to the vertical joint between the wall panels 6. Since it is fixed to the plate-shaped base end portion 12a of the member 12 by welding, the flange portion 11b that abuts the front and back surfaces of the wall panel 6
Even if the wall panel 6 is warped, it is possible to finish the surface smooth by matching the misalignment between the surfaces of the adjacent wall panels 6. Furthermore, even when a large load is applied to a part of the adjacent wall panels 6, the effect of effectively sharing the load with the adjacent wall panels 6 can be achieved at the same time.

The position where the rod-shaped member 12 is provided on the upper edge surface 6a of the wall panel 6 is 100 m from the vertical joint.
It is located at a distance of m, and the thickness of the wall panel 6 is 100 mm.
On the other hand, it is provided at the center position. On the contrary,
The width of the substantially flat surface portion 11a of the horizontal member 11 having a substantially L-shaped cross section is 5
The plate-like base end portion 12 of the rod-like member 12 is set to about 0 mm.
It is configured so that the welding length to a can be sufficiently secured. In this first embodiment, the diameter of the plate-like base end portion 12a is set to 5
The thickness is 0 mm, and the substantially flat surface portion 11a and the plate-shaped base end portion 12a
With the above-mentioned configuration, the welding length of
It is possible to secure a welding length of about 0 mm.

Although the height of the brim portion 11b is 30 mm, it may be larger than 80 mm, for example. A larger dimension is more effective as a surface pressing member for obtaining surface accuracy. However, if there is no interior finish on the inside of the wall panel 6, if the size is too large, the appearance may be unsightly. Generally, the height of the brim portion 11b is preferably set in the range of about 20 mm to 100 mm.

As the horizontal member 11 having a substantially L-shaped cross section, a long member having three or more wall panels 6 is used.
As long as it is provided so as to straddle at least two adjacent wall panels 6, a short one may be used. For example, the length of the horizontal member 11 having a substantially L-shaped cross section can be set to 200 mm.

<Second Embodiment> FIG. 2 shows a second embodiment of the present invention.
It is a second embodiment and is a perspective explanatory view showing a wall panel mounting structure and a perspective view of a dedicated metal object.

In this embodiment, unlike the first embodiment, in the vertical joints between the adjacent wall panels 6, from the vicinity of the height position of the ruler angle 2, the upper edge face 6a of the wall panel 6 is formed.
Up to the position, the flat bar 13 is provided so as to fit in the center of the thickness of the wall panel 6.
The upper end of the horizontal member 11 having a substantially L-shaped cross section.
It is passed through a slit-shaped notch 11c provided in a and is fixed by welding from above. As described above, the horizontal member 11 having a substantially L-shaped cross section is attached by welding to the rod-shaped member 12 having the plate-shaped base end portion 12a at the upper end driven into the upper edge surface 6a of the wall panel 6 near the vertical joint. Not only the wall panel 6 but also the flat bar 13 is welded and fixed at the vertical joint position of the wall panel 6, so that even if the adjacent wall panels 6 are largely misaligned, the misalignment is corrected and It is possible to correctly draw the surface of the surface, and the above-mentioned rubbing does not become apparent even with the lapse of time.

Further, since the upper end of the flat bar 13 is passed through a slit-shaped notch 11c provided in a substantially flat surface portion 11a of the horizontal member 11 having a substantially L-shaped cross section and fixed by welding from above, it is easy. Since it can be attached by various works and can be fixed by downward welding, it is easy to secure the quality of the welded portion.

In this method, since the upper end portion of the panel is fixed by using the flat bar, the load acting on the wall panel 6, particularly the load acting on the upper end portion, is the anchor steel bar 7
a, 7b, O bolts 8a, 8b, mounting hardware 9, nut 1
0 from the ruler angle 2 to the horizontal beam 1, but also from the ruler angle 2 to the horizontal beam 1 via the horizontal member 11 having a substantially L-shaped cross section, the flat bar 13, and the vertical base angle 4. The load can be shared and transmitted effectively.

<Third Embodiment> FIG. 3 shows a third embodiment of the present invention.
It is a second embodiment and is a perspective explanatory view showing a wall panel mounting structure and a perspective view of a dedicated metal object.

In this embodiment, the flat bar 13 is used as in the second embodiment, but the mounting structure on the upper edge face 6a of the wall panel 6 is different, and the flat bar 13 of the flat bar 13 is connected via the connecting piece 14. The upper end portion and the substantially flat surface portion 11a of the horizontal member 11 having a substantially L-shaped cross section are connected and fixed. The upper end of the flat bar 13 is welded and fixed downward from above by passing through the slit-shaped hole 14c provided in the flat bar fixing portion 14a of the connecting piece 14.

On the other hand, the connecting member 14 is provided with the horizontal member fixing portion 1 with respect to the substantially flat surface portion 11a of the horizontal member 11 having a substantially L-shaped cross section.
4b are piled up, and also fixed by welding downward from above. In this way, using the tie hardware 14, with a simple operation,
It is fixed by downward welding, which makes it easy to ensure welding quality. In addition, the rod-shaped member 12 having the plate-shaped base end portion 12a at the upper end portion
Further, the substantially flat surface portion 11a of the horizontal member 16 having a substantially L-shaped cross section is attached by welding, as in the second embodiment.

In this method, since the dedicated metal piece 14 is used, it is easy to secure the welding length even when the substantially flat portion 11a of the horizontal member 11 having a substantially L-shaped cross section has a small width dimension.

Also, unlike the second embodiment, the cross section is substantially L
Since it is not necessary to directly provide the slit-shaped notch 11c in the substantially flat surface portion 11a of the character-shaped horizontal member 11, a general-purpose member such as an angle (angle steel) can be used. When the substantially flat portion 11a of the horizontal member 11 having a substantially L-shaped cross section has a small width dimension and equilateral mountain steel with a small cross section of about 30 mm × 30 mm, which is a general-purpose member, is used, the cross section abutting against the inner surface of the wall panel 6 The height of the brim 11b of the substantially L-shaped horizontal member 11 can be reduced to 30 mm, and the size of the brim 11b exposed on the inner surface can be minimized. Even if there is, it is possible to put it in such a way that it is not unsightly when viewed from the inside.
Of course, as an interior finish, when the inner surface of the wall panel 6 is hidden by mortar or a molding board, the cross section is approximately L.
As the horizontal member 11 having a character shape, for example, an isosceles member having a size of 30 mm × 75 mm is used, and the height dimension of the brim portion 11b of the horizontal member 11 having a substantially L-shaped cross section that abuts on the inner surface of the wall panel 6 is increased to 75 mm. But there is no problem. in this way,
By increasing the height of the brim portion 11b, it is advantageous that the pressing member for correcting the displacement between the adjacent wall panels 6 and providing the surface accuracy can increase the area of the pressing portion.

<Fourth Embodiment> FIG. 4 shows a fourth embodiment of the present invention.
It is a second embodiment and is a perspective explanatory view showing a method for obtaining the surface accuracy of the wall panel.

In this embodiment, when the wall panel 6 is attached in the third embodiment, the vise 15 is used to form the wall panel 6 and the flange portion 11b of the horizontal member 11 having a substantially L-shaped cross section (not shown).

As described above, according to the first aspect of the present invention, a horizontal member having a substantially L-shaped cross section is predetermined with respect to two bar-shaped members provided near the vertical joints at the upper ends of the adjacent wall panels. It is securely welded and fixed in the length dimension, and since the brim portion of the horizontal member having a substantially L-shaped cross section is in contact with the inner side surface of the adjacent wall panel, when the adjacent wall panels are displaced from each other, It is possible to correct and correct the deviation without depending on the dimensional accuracy of the wall panel, and it is possible to prevent the mutual deviation of the adjacent wall panels from becoming apparent due to a change with time.

Further, when the sash is stored on the wall panel, the metal object is not exposed on the vertical surface portion on the outer surface side of the wall panel, so that the appearance does not become unsightly.

Further, since the wall panels are connected to the upper end portion by the rod-shaped member via the horizontal member having a substantially L-shaped cross section, the load can be borne by the entire wall surface.

According to the invention of claim 2, in addition to the effect of the invention of claim 1, in addition to the positions of the two bar-shaped members near the vertical joints respectively provided on the two adjacent wall panels, they are adjacent to each other. The cross section is approximately L even near the top of the vertical joint positions of the wall panels.
The character-shaped horizontal member is also fixed to the flat bar,
Since the horizontal member having a substantially L-shaped cross section is fixed at a total of three places, the correction force for correcting the displacement between the two adjacent wall panels can be more effectively applied.

Furthermore, in addition to the fact that the wall panel is fixed at two positions, that is, the position of the ruler steel material installed on the upper flange of the horizontal beam and the position of the receiving steel material installed at the bottom of the wall panel, Since the upper part is directly or indirectly attached to the horizontal beam through a flat bar with a substantially L-shaped cross section, the load acting on the wall panel is
It is also possible to have a mounting structure that can withstand a larger load.

According to the invention of claim 3, in addition to the effect of the invention of claim 2, a horizontal member having a substantially L-shaped cross section provided with a slit-shaped hole or notch and a flat bar are welded and fixed from above. Therefore, it is possible to improve the workability at the construction site with a simple work and to easily secure the welding quality.

According to the invention of claim 4, in addition to the effect of the invention of claim 3, a slit-like hole or notch for inserting the upper end portion of the flat bar into the horizontal member itself having a substantially L-shaped cross section is provided by a connecting piece. Since it is not necessary to form the above, a general-purpose angle steel such as an angle can be used as the horizontal member having a substantially L-shaped cross section. The cross section is substantially L
It is possible to reduce the width of the substantially flat portion of the character-shaped horizontal member, reduce the weight of the member, and improve workability on site.

According to the fifth aspect of the invention, when the panel is displaced, the horizontal member having a substantially L-shaped cross section can be directly clamped with a vise to easily correct the displacement and temporarily fix the panel. After welding and fixing the L-shaped horizontal member to the specified member,
The vise can be removed. Therefore, it is not necessary to prepare a correction attachment plate and it is not necessary to prepare many vise.
