Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ALC (lightweight cellular concrete) wall panel mounting structure for a building, and more particularly to an ALC wall panel mounting structure suitable for placing a veranda in a dry construction method.

[0002]

2. Description of the Related Art A variety of conventional ALC wall panel mounting structures have been proposed. Among them, an intermediate portion and a lower portion of the ALC wall panel in the height direction are provided on an upper flange of a horizontal beam. Two conventional examples disclosed in Japanese Patent Application Laid-Open No. 9-203151, which is a mounting structure of an ALC wall panel fixed to a ruler steel material and a receiving steel material installed at the lowermost portion of the ALC wall panel, will be described.

[0003] In a first conventional example shown in FIG.
A vertical angle 61 is fixed vertically below via a short angle 53, and a receiving angle 63 that receives and supports the lower end of the ALC wall panel 62 on the vertical angle 61.
Are disposed horizontally. Further, a ruler angle 52 is fixed to the horizontal beam 51, and mounting brackets 64 and bolts 64a are provided at a predetermined pitch in the receiving angle 63 and the ruler angle 52. And this mounting bracket 64
And the bolts 64a are screwed into and fixed to the embedding nuts 62a provided at only one portion of each of the lower end portion and the middle portion of the ALC wall panel 62 at substantially the center in the horizontal width direction. As described above, in the first conventional example, the position of the ruler angle 52 installed on the upper flange 51a of the horizontal beam 51,
At the position of the receiving angle 63 installed at the lowermost part of the ALC wall panel 62, only one portion of the ALC wall panel 62 at a substantially central portion in the width direction is fixedly attached.
This was the mounting structure of the LC wall panel 62.

In the second conventional example shown in FIG. 10, similarly to the first conventional example, the receiving angle 63 and the ruler angle 52 are provided with mounting brackets 64 and bolts 64a at a predetermined pitch. The number of mounting brackets 64 and bolts 64a provided on the angle 63 is
2 of the number of mounting brackets 64 and bolts 64a provided in
It is set to double. And this mounting bracket 6
At the lower end of the ALC wall panel 62, the bolts 4a and the bolts 64a are fitted and fixed by being screwed into embedding nuts 62a provided at two locations on the left and right sides in the lateral width direction. Thus, in the second conventional example, the upper flange 51a of the horizontal beam 51
At the position of the ruler angle 52 installed in the ALC wall panel 62, only one location in the approximate center of the width direction of the ALC wall panel 62 is fixed and attached, while the receiving angle 63 installed in the lowermost part of the ALC wall panel 62 is attached. At the position, the mounting structure of the ALC wall panel 62 was fixedly mounted at two positions on the left and right sides of the ALC wall panel 62 in the lateral width direction.

[0005]

However, the mounting structure in the above-mentioned first conventional example is an ALC wall panel 62.
Is a mounting structure of the ALC wall panel 62 to which only one of the middle part and the lower part in the height direction of the ALC wall panel 62 is mounted. Since the lower mounting part is provided close to the lower edge of the ALC wall panel 62, The lightweight cellular concrete portion of the wall panel 62 does not exist much below the embedded nut 62a of the lower mounting portion, and therefore, compared to the strength of the mounting portion at the middle portion in the height direction, the lower portion in the height direction There was a problem that the strength of the mounting portion was reduced.

[0006] For example, the dimension from the ruler angle 52 (position of the middle part) adopted as the veranda structure of the building to the receiving angle 63 (position of the lower part) is generally 400.
mm. Furthermore, the dimension from the ruler angle 52 (the position of the middle part) to the upper end part of the ALC wall panel 62 is:
Generally, it is about 1100 mm. In this state, when a human horizontal load of 180 kgf is applied to the upper end of the ALC wall panel 62, due to the moment, in the case of a horizontal load outward of the building (outside of P), the vertical direction is applied. The load (middle P) acting on the middle part increases, while the load (lower P) acting on the lower part in the height direction increases in the case of a horizontal load (inside P) in the room direction of the building. . The size is calculated as follows.

The load acting on the middle part in the height direction (medium P)
The load acting on the lower part in the height direction (under P) is 180 kgf (outside P) × 1575 mm ÷ 475 mm = 597 kgf (under P). Load acting on the middle part in the height direction (medium P)
And the load (below P) acting on the lower part in the height direction differs only by about 20%. In addition, the calculation based on the above formula was performed on the assumption that the horizontal load (outside P) of the building in the outside direction and the horizontal load (inside P) of the building in the room direction were equal. As described later, there is a report that the horizontal load (inside P) of the building toward the interior of the building is larger than the horizontal load (outside of P) of the building, as described later. . For example, according to "Study on Human Forces Acting on Buildings Part 1" (Report of the Architectural Institute of Japan, No. 298, December, 1980), the results of measuring the force applied to a handrail by an adult male, As the load, 270 kgf / m as the horizontal load (outside P) of the building outward,
360k as horizontal load (inside P) in the building interior direction
gf / m.

When the design load proposed in this document is substituted into the above and recalculated, the following is obtained. The load acting on the middle part in the height direction (in P) is: P = 270 kgf (outside P) x 1575 mm ７５ 475 mm = 895 kgf The load acting on the lower part in the height direction (P lower) is P lower = 360 kgf (inside P) × 1100 mm ÷ 400 mm = 990 kgf. Thus, assuming that the horizontal load (inside P) in the room direction of the building is larger than the horizontal load (outside P) in the outward direction of the building. When weighting is applied, the load acting on the middle part in the height direction (P medium) and the load acting on the lower part in the height direction (P
The magnitude of (lower) is reversed, and the load (lower P) acting on the lower part in the height direction is larger by about 10%.

As described above, although the strength of the lower mounting portion in the height direction often needs to be larger than the strength of the mounting portion in the middle portion in the height direction,
On the contrary, the first conventional example has a problem that the strength of the lower mounting portion in the height direction is lower than the strength of the mounting portion in the middle portion in the height direction. It should be noted that, in the calculation by the above formula, AL from the receiving angle 63 (the lower position).
The dimension up to the upper end of the C wall panel 62 is 400 mm + 1
100mm = 1500mm, not 1575mm,
From the receiving angle 63 (the lower position) to the ruler angle 52
The distance to (the position of the middle part) is 4 mm instead of 400 mm.
The reason why the distance is set to 75 mm is that the center of rotation in relation to the moment is not the position of the mounting portion bolt 62a with respect to the receiving angle 63, but the position of the lower end surface of the ALC wall panel 62 about 75 mm below it. On the other hand, in the calculation based on the above equation, the center of rotation in relation to the moment is the position of the mounting portion bolt 62a with respect to the ruler angle 52, so that there is no need to adjust the dimensions in relation to such a moment.

In the second conventional example, the ALC wall panel 62 is fixedly attached to two lower left and right sides in the width direction of the ALC wall panel 62 below the ALC wall panel 62 in the height direction. The mounting structure of the panel 62,
The attachment portions at the locations are provided with the same structure. However, since the lower mounting portion is fixed at two places on the left and right sides, especially when a human horizontal load acts on the upper end of the ALC wall panel 62 in the room direction of the building, it is fixed at two places. Despite this, the mounting strength is not improved up to twice the mounting strength of one mounting part. The reason is that since the ALC wall panel 62 is fixed to the mounting bracket 64 and the bolts 64a near the both ends in the width direction, the tightening force of the bolts of the mounting portions on the left and right sides is not necessarily equal, so that it is always necessary to say that. It is considered that an eccentric load acts as much as possible. For this reason, it is necessary to provide two mounting portions capable of withstanding a high load at the lower portion in the height direction of the ALC wall panel 62, and a corresponding effect cannot be obtained as the strength of the mounting portion despite an increase in mounting time and the like. Was a problem.

Further, as a common problem of the first conventional example and the second conventional example, a hanging rib piece 64b of the mounting bracket 64 and a bolt head of the bolt 64a are provided at the lower part in the height direction of the ALC wall panel on the indoor side. Because of the projections, the ceiling material (not shown) interferes with the hanging rib pieces 64b of the mounting bracket 64 and the bolt heads of the bolts 64a due to interference with the eaves ceiling, making it difficult to construct the ceiling material. Sometimes occurred. Along the upper edge of the ALC wall panel 62,
Since the horizontal member is not provided, when the ALC wall panel 62 is warped, the upper part of the ALC wall panel 62 may be out of plane, and may be uneven. for that reason,
It is necessary to insert mortar between the vertical joints of the ALC wall panel 62 and fix it. However, until the mortar is hardened and the adjacent ALC wall panel 62 can be restrained, the adjacent ALC wall panel 62 is temporarily stopped. It was necessary to temporarily fix the out-of-plane position.

In addition, in the first or second conventional example, since the ALC wall panels 62 are not integrated with each other, a concentrated load acts on the ALC wall panels 62 in addition to the meaning of the above-described warpage correction. In this case, in order to distribute the load to the left and right adjacent ALC wall panels 62,
It was necessary to fill the joints between the ALC wall panels 62 with mortar and use a wet construction method. Therefore, mortar work is troublesome, and the mortar and the ALC wall panel are highly likely to be soiled. In order to develop strength, it is necessary to provide a hardening and curing period for the mortar. As described above, even when the ALC wall panel of the other general part is constructed by the dry construction method, there is a problem that the mortar needs to be kneaded and constructed only for the construction of the veranda part.

Further, when the ALC wall panel 62 is manufactured at a factory, it is necessary to set the position of the embedding nut 62a in advance.
It is difficult to adjust the position when the mounting position is displaced. In addition, in order to fix the embedding nut 62a at a predetermined position of the reinforcing steel bar at the factory, the ALC wall panel 62 is manufactured on a different production line from other general ALC wall panels without the embedding nut 62a. There is also a problem that labor is required, such as the necessity of manufacturing the device. An object of the present invention is to provide an ALC wall panel mounting structure that can solve the above-mentioned problem.

[0014]

According to a first aspect of the present invention for achieving the above object, an intermediate portion and a lower portion of an ALC wall panel in a height direction are provided on an upper flange of a horizontal beam. A mounting structure of an ALC wall panel fixed to a ruler steel material and a receiving steel material installed at a lowermost portion of the ALC wall panel, wherein a lower part of the ALC wall panel in a height direction is an ALC wall panel.
At least one of a location at a substantially central portion in the width direction of the wall panel and at least one of both or both of the left and right sides in the width direction of the ALC wall panel, a total of two or more locations are attached to the receiving steel material. It is a mounting structure of a characteristic ALC wall panel.

In the present invention, the mounting structure in which the ALC wall panel is fixedly attached to a ruler steel material or a receiving steel material which is installed at an intermediate portion and a lowermost portion of the ALC wall panel is referred to as AL.
Including the case where the mounting bracket having a bolt insertion hole or the like for fixing the C wall panel is fixed to the ruler steel or the receiving steel, the fixing position of the ALC wall panel is slightly above the ruler steel or the receiving steel. This is a structure including the case where it is shifted.

Further, the ruler steel material provided on the upper flange of the horizontal beam is not limited to the case where it is directly fixed to the upper flange of the horizontal beam. This structure includes a case where a member (such as a bracket material) is fixed, and a ruler steel material is fixed to the adjusting member, so that the horizontal member is indirectly fixed to the upper flange.
Furthermore, the horizontal beam in the present invention is not limited to the case of a steel frame, but also includes a case of being made of reinforced concrete. In the case of such a reinforced concrete horizontal beam, “upper surface of horizontal beam” means “upper flange of horizontal beam”, and “lower surface of horizontal beam” means “lower flange of horizontal beam”.

According to the present invention, at the lower part in the height direction of the ALC wall panel, one portion at the substantially central portion in the width direction of the ALC wall panel is fixed, and further, on both the left and right sides of the ALC wall panel in the width direction. Since at least one of both parts or any one of the parts is additionally attached to the receiving steel material, compared to the first conventional example, the mounting strength of the intermediate part in the height direction is higher than that of the first conventional example. The problem that the strength of the lower mounting portion is reduced can be avoided by appropriately adding a mounting portion to both or either of the left and right sides in the width direction of the ALC wall panel. The number of additional parts to be provided depends on the dimensional relationship of ALC wall panels, ruler steel and receiving steel in the height direction, and uses such as verandas and common corridors where ALC wall panels are used in buildings. It can be determined by appropriately considering it. Especially,
If it is sufficient to slightly increase the strength of the lower mounting portion in the height direction, one additional mounting portion may be provided on either the left or right portion of the ALC wall panel in the width direction. Good.

It is to be noted that, at the lower part in the height direction of the ALC wall panel, at least one of the mounting part provided at the substantially central part in the width direction and the right and left both sides in the width direction. The provided mounting portions may have the same structure and strength, or may have different structures and strengths. A mounting portion provided at an intermediate portion in the height direction of the ALC wall panel and an arbitrary mounting portion of two or more lower portions in the height direction of the ALC wall panel have the same structure and strength. Or a configuration having a different structure or strength. However, for dimensions such as veranda walls that are common in buildings, the strength of the mounting part provided in the middle of the ALC wall panel in the height direction is determined by ALC.
It is desirable that the strength is set to be equal to or higher than the strength of an arbitrary mounting portion among two or more lower portions in the height direction of the wall panel.

Next, the second invention of the present invention relates to the ALC
At the lower part of the wall panel in the height direction, a fixing part A is provided at one location substantially at the center of the ALC wall panel in the lateral width direction.
A fixing portion B is provided in at least one of both and / or one of the left and right sides in the width direction of the wall panel, and the strength of the fixing portion B is smaller than the strength of the fixing portion A. An ALC wall panel mounting structure according to claim 1, that is, the first invention.

According to the second aspect of the present invention, the fixed portion A provided at one position substantially at the center of the ALC wall panel in the width direction at the lower portion in the height direction of the ALC wall panel is AL.
Since the strength of the mounting portion is set to be greater than that of the fixing portion B provided on at least one of both or either of the left and right sides in the width direction of the C wall panel, most of the load on the fixing portion A By properly adding the fixing portion B, insufficient strength at the lower portion of the ALC wall panel in the height direction can be compensated while finely adjusting.

Next, according to a third aspect of the present invention, a rod-shaped member having a plate-like base end at a lower end is provided at one position substantially at the center in the width direction of the ALC wall panel and in the width direction of the ALC wall panel. 2. At least one or both of the left and right sides of the ALC wall panel, at least one of which is driven into the lower edge face of the ALC wall panel, and is welded and fixed to the receiving steel material. 2 is an ALC wall panel mounting structure.

In the third aspect of the present invention, a rod-shaped member having a plate-like base end at the lower end is driven into the lower edge of the ALC wall panel as a mounting portion structure at a lower portion in the height direction of the ALC wall panel. Therefore, unlike the first conventional example and the second conventional example, the hanging rib pieces 64b of the mounting bracket 64 and the bolt heads of the bolts 64a protrude toward the interior of the room, unlike the first conventional example and the second conventional example. The hanging rib pieces 64b of the mounting bracket 64 and the bolt heads of the bolts 64a do not interfere with each other, so that there is no problem that the installation of the ceiling material becomes difficult.

Next, according to a fourth aspect of the present invention, as the fixing portion B, a rod-shaped member having a plate-shaped base end portion at a lower end portion is provided.
The mounting structure of the ALC wall panel according to claim 2, wherein the structure is driven into the lower edge face of the LC wall panel and fixed by welding to the receiving steel material. According to the fourth aspect of the present invention, a rod-shaped member having a plate-like base end at the lower end is driven into the lower edge of the ALC wall panel as a mounting structure of the fixing portion B at a lower portion in the height direction of the ALC wall panel. In this case, the simple structure of welding and fixing to the receiving steel material makes it possible to appropriately determine the strength shortage due to the fixing portion A and to reinforce it by adding, and as compared with the first or second conventional example. It is not necessary to bury the embedding nut 62a in a factory or the like in advance, and the workability at the construction site can be additionally satisfactorily reinforced.

The fixing portion B using a rod-shaped member having a plate-like base end is set so as to have a weaker mounting portion strength than the fixing portion A. Next, according to a fifth aspect of the present invention, a flat bar is installed on the vertical joint between the ALC wall panels from at least near the upper flange of the horizontal beam to near the uppermost portion of the ALC wall panel. ALC is directly or indirectly fixed to the receiving steel material, and has a predetermined length in the longitudinal direction and a width corresponding to the thickness of the ALC wall panel at the top of the ALC wall panel. A substantially flat portion that is in contact with or close to the upper foreface of the wall panel;
A substantially U-shaped cap having a brim portion abutting on the front and back surfaces of the wall panel is fitted over the upper edge surface of the adjacent ALC wall panels to integrate the plurality of adjacent ALC wall panels. The ALC wall panel mounting structure according to any one of claims 1 to 4, wherein the cap is fixed to the flat bar, and the cap is fixed to the flat bar.

In the fifth aspect of the present invention, the flat bar is disposed between the vertical joints of the ALC wall panels, and the flat bar extends from at least near the upper flange of the horizontal beam to near the uppermost portion of the ALC wall panel. Will be installed. Then, as shown in FIG. 6, for example, a hook 10 a provided integrally with the flat bar 10 is suspended and fixed to an upright piece 2 a of a ruler angle (ruler steel) 2 fixed on the horizontal beam 1. In the example shown in FIG. 6, the hook portion 10 a is obtained by cutting a plate material different from the flat bar 10 and is fixed to the flat bar 10 in advance by welding or the like. By cutting, a hook portion can be provided and fixed to the ruler steel material, or the long side end surface of the flat bar can be directly welded and fixed to the ruler steel material without providing the hook portion.

The flat bar receives the lowermost portion and is fixed to the horizontal piece 4a of the angle 4 as shown in FIG. 6, for example. In the example shown in FIG. 6, the flat bar 10 is directly fixed to the receiving angle (receiving steel material) 4.
It is also possible to indirectly fix another plate or metal to the lowermost portion of the flat bar in advance and fix the plate or metal to a steel material. For example, as shown in FIG. 7, it is also possible to indirectly fix to the receiving angle (receiving steel material) 4 via the vertical angle 10c.

As described above, the present invention provides a flat bar,
When fixing to the ruler steel material installed on the upper flange of the horizontal beam, or when fixing it to the receiving steel material installed at the bottom of the ALC wall panel, it is possible to directly fix it, or to use other plate materials or hardware. This also includes fixing indirectly through the method. The flat bar is, for example, as shown in FIG. 8, a ruler angle (ruler steel) 2 installed on the upper flange 1 a of the horizontal beam 1 and a receiver angle (receiver steel) installed at the bottom of the ALC wall panel 5. 4 and a short angle 3 installed on the lower flange 1b of the horizontal beam 1
It may be fixed directly or indirectly to the camera. As described above, by fixing the horizontal beam to a short angle or the like installed on the lower flange thereof, the horizontal beam can be more firmly fixed to the horizontal beam, which is preferable.

Further, according to the present invention, the top of the ALC wall panel has a predetermined length in the longitudinal direction and the ALC wall panel has a predetermined length.
A substantially flat portion having a width corresponding to the thickness of the wall panel and abutting on or near the upper edge surface of the ALC wall panel; and being connected orthogonally to the substantially flat portion and contacting the front and back surfaces of the ALC wall panel. A cap having a substantially U-shaped cross section having a contacting brim portion is fitted over the upper foreface between adjacent ALC wall panels so as to integrally lock the plurality of adjacent ALC wall panels. The cap is fixed to the flat bar described above. The ALC wall panel is also fixed at the upper end by the cap which is indirectly fixed to the horizontal beam and the receiving steel material via the flat bar. The cap and the flat bar may be fixed by welding or by an adhesive material, but the most preferable fixing means is welding.

As described above, the fifth invention of the present invention
Since a vertical bar (or a member obtained by processing a flat bar), which is a general-purpose member, is used as the vertical member that passes between the vertical joints of the C wall panel, loss of the member can be reduced, the configuration can be simplified, and the cost can be reduced. . Further, since the flat bar is contained within the thickness of the ALC wall panel, it is possible to save labor for finishing the inside.

Further, since the cap having a substantially U-shaped cross section is fixed across the adjacent ALC wall panels at the upper end of the flat bar, the concentrated load is distributed to the left and right ALC wall panels. At the same time, the load can be effectively transmitted to the flat bar, and even if the ALC wall panel itself is warped, the surface accuracy is secured between the left and right ALC wall panels. I do.
It is preferable that the inner dimension of the brim portion of the cap is set slightly smaller than the thickness dimension of the ALC wall panel, and the cap is set so as to be knocked. For example, if the thickness is 1
In the case of an ALC wall panel of 00 mm, if the inner dimension of the flange of the cap is set to about 99 mm, the capping effect is effectively exerted to ensure surface accuracy between the left and right ALC wall panels it can.

Furthermore, there is provided a mounting structure which can be easily constructed without the need for mounting the cap on the upper edge surface of the ALC wall panel other than the flat bar. More specifically, the fifth invention of the present invention is a flat bar that passes between the vertical joints of the ALC wall panel, and has a length corresponding to the maximum height dimension of the ALC wall panel assumed at a construction site in advance in a factory or the like. It can be prepared as a special member processed in the above, and after it is carried into the construction site, it can be cut into appropriate dimensions corresponding to the height dimensions of the individual ALC wall panels, so the flat bar is prepared as a standardized member As well as
And the vertical member between the vertical joints can be easily configured,
Cost reduction is also possible.

Further, the fifth invention of the present invention relates to a vertical joint at least from the upper flange of the horizontal beam to the vicinity of the uppermost portion of the wall, in other words, to the portion where the ALC wall panel rises from the floor slab to the upper portion. Since flat bars are installed and reinforced as reinforcing steel materials, it is possible to fit the flat bars within the thickness of the ALC wall panel. Since it is no longer exposed to the inside of the ALC wall panel, it is possible to fit the end of the waterproof finish directly into the back surface of the ALC wall panel by making a groove or the like. As a result, the thickness of the inside finish can be eliminated or reduced, and the inside finishing work can be labor-saving.

At this time, the groove size 10 to 2 for waterproofing
Set the AL so that the flat bar does not come to a depth of 0 mm.
A flat bar is preferably provided at a vertical joint between the C wall panels at a position separated from the inner surface of the ALC wall panel by 10 to 20 mm or more. For example, when the thickness of the ALC wall panel is 100 mm, the width of the flat bar is 50 mm, and the flat bar is provided at the center of the ALC wall panel in the thickness direction, the inner surface of the ALC wall panel is formed. The flat bar is located at a position 25 mm farther away, which is preferable. In this case, the position of the flat bar is 25 mm away from the inner surface of the ALC wall panel,
Also in the case where the sealing is performed on the vertical joint on the outer surface side or the inner surface side, there is no shortage in the installation depth of the sealing, which is preferable.

At the top of the ALC wall panel,
A substantially flat portion having a width corresponding to the thickness of the ALC wall panel and abutting or approaching the upper edge surface of the ALC wall panel;
A cap having a substantially U-shaped cross section, which is connected perpendicularly to the substantially flat portion and has a brim portion that comes into contact with the front and back surfaces of the ALC wall panel, is fitted over the upper end portions of adjacent ALC wall panels. Since the plurality of adjacent ALC wall panels are integrally locked, and the cap is fixed to the flat bar, the adjacent ALC wall panels can be formed without a wet construction method in which mortar is inserted into the vertical joint. The wall panel can be integrally fixed, and even if a load is concentrated on one place of the ALC wall, the load is applied to the left and right adjacent AL.
The C wall panel can be borne.

At the same time, even when the ALC wall panel is warped and the ALC wall panel is overturned at the upper part of the veranda, the cap is fitted over the adjacent ALC wall panel. The accuracy of the wall is not difficult to achieve. More specifically, the collar portion of the cap is A
Since the LC wall panels are pressed so as to be restrained from both sides of the front and back surfaces, the position of the adjacent ALC wall panels can be corrected more effectively in the out-of-plane direction. In addition, since there is no need to continuously arrange horizontal members along the upper edge of the ALC wall panel, efficient construction is possible.

On the other hand, when compared with the first or second conventional example, a large load does not act even in the middle or lower part of the ALC wall panel in the height direction. There is no need to bury a high-strength embedding nut or the like in advance in the middle or lower part, and the mounting portion can have a relatively light structure. Further, the internal stress generated in the ALC wall panel itself can be reduced, and therefore, the amount of reinforcing reinforcing bars installed inside the ALC wall panel can be reduced. The cap is provided with a slit-like hole or notch in a substantially flat portion near the vertical joint position of the ALC wall panel at a central position in the thickness direction of the ALC wall panel. Is passed through the slit-shaped hole or notch, and the cap and the flat bar are fixed by welding from above, which can be fixed by simple on-site work only by welding from the top, a preferable configuration. It can be said that.

Next, a sixth invention of the present invention is characterized in that a rod-like member having a plate-like base end at the upper end is driven into the upper small face of the ALC wall panel, and is fixed to the cap by welding. The mounting structure of an ALC wall panel according to claim 5, wherein As in the sixth aspect of the present invention, since the plate-like base end of the upper end of the rod-like member driven into the upper edge of the ALC wall panel is fixed to the cap, the cap can be more securely attached to the ALC wall. It can be fixed to the upper edge of the panel. For this reason, even when the cap tree or the handrail with a handrail provided further above the ALC wall panel is fixed to the substantially flat portion, the cap tree or the handrail with the handrail can be firmly fixed without rattling.

Further, a substantially flat portion of the cap is placed over the plate-like base end at the upper end of the rod-shaped member from above, and a side edge of the substantially flat portion on the upper surface of the plate-like base end is viewed from above. It is possible to fix by simple on-site work just by welding. Finally, the seventh invention of the present invention is characterized in that a rod-like member having a plate-like base end at the upper end is driven into the upper small face of the ALC wall panel, and is welded and fixed to the cap, and
The ALC wall panel mounting structure according to claim 5, wherein adjacent plate-like base ends are connected and fixed to each other with a steel plate arranged in contact with an upper edge surface of the ALC wall panel.

As described above, in the seventh aspect, the adjacent plate-like base ends welded and fixed to the side edges of the adjacent caps are connected and fixed by the steel plate, and the adjacent caps are indirectly connected. Are continuously connected and fixed. Therefore, it is possible to reliably fix the cap and the steel plate to the upper edge surface of the ALC wall panel. Therefore, it is possible to fix the cap and the handrail with the handrail provided further above the ALC wall panel at an arbitrary position with respect to the cap or the steel plate, and more securely fix the cap and the handrail with the handrail without rattling. Can be done. Further, since the steel sheet only has a function of connecting adjacent plate-shaped base ends,
A steel plate, which is a general-purpose member, can be appropriately cut and used. Of course, a steel plate cut in advance to a predetermined size may be used.

Therefore, in buildings, such as commonly used dimensional veranda parts such as porch
With the structure of the LC wall panel 5, it is possible to adjust the strength of the middle part in the height direction and the strength of the lower part in the height direction so as to be almost equal.

The lower part of the ALC wall panel 5 in the height direction is different from the structure using the O-bolt 7 or the like, which is the mounting part structure at the substantially center part in the width direction, in the lower part on the right side in the width direction. Since the strength of the mounting portion of the structure using the rod-shaped member 12 driven into the fore-edge surface is reduced, most of the load is borne by the structure using the O-bolt 7 or the like, which is the mounting portion structure at the substantially central portion in the width direction. However, by supplementing the lack of strength with a structure using the bar-shaped member 12 that is driven into the lower edge on the right side in the width direction, it is possible to effectively secure the strength of the mounting portion. According to the configuration of the second invention, AL

The structure in which the LC wall panel 5 is bolted from the indoor side surface, while the structure using the rod-shaped member 12 on the right side in the width direction as the fixing portion B fixes the ALC wall panel 5 from the lower foreface. Unlike the second conventional example, there is no problem that the tightening force of the bolts of the mounting portions on the right and left sides is not uniform. Therefore, the strength of the fixing portion A is effectively reduced with respect to the strength of the fixing portion A. B intensity can be added. As described above, it can be said that it is preferable to use both the structure of bolting from the indoor side surface and the structure of fixing from the lower edge surface.

If a plurality of projections (not shown) are provided on the bar-shaped portion of the bar-shaped member 12 provided on the lower edge surface of the ALC wall panel 5 in the height direction, the ALC wall panel 5 can be installed at the time of installation.

In this embodiment, an attachment portion with two bar-shaped members 12 is additionally provided on the right side of the fixing portion B in the width direction. in this way,
It is also possible to concentrate the mounting portion on either the right side or the left side. Also in this case, similarly to the third embodiment, the ceiling material can be easily installed.

[0053]

Sixth Embodiment FIG. 6 is a sixth embodiment according to the present invention, and is a perspective view showing a mounting structure of an ALC wall panel and a perspective view of a special hardware. In this embodiment, as in the first embodiment, the lower part of the ALC wall panel 5 in the height direction is a lower end as an attachment part other than the O-bolt 7 provided at a substantially central part in the lateral width direction. A bar-shaped member 12 having a plate-like base end portion 12a at its portion is driven into the lower edge of the right side of the ALC wall panel 5 in the width direction, and is fixed to the horizontal piece 4a of the receiving steel material 4 by welding. However, the anchor steel bar 6 with which the O-bolt 7 is engaged is provided longer than in the first embodiment, and therefore, the anchor steel bar 6 and the bar-shaped member 12 are provided at positions close to each other. Anchor steel rod 6 and rod-shaped member 1
2 is generally located at the approximate center of the thickness of the ALC wall panel 5, but in order to avoid contact, either the anchor steel bar 6 or the rod-shaped member 12 is moved from the approximate center of the thickness to the outside or the chamber. Displace it inside. In order to secure the strength of the entire mounting portion, the position of the rod-shaped member 12 is shifted from the substantially center position to the outside, so that the anchor steel rod 6 and the rod-shaped member 1 are shifted.
The direction that avoids contact 2 is preferred.

The vertical joints between the ALC wall panels 5 are arranged on the vertical joints of the ALC wall panels 5 from the height of the receiving angle 4.
Up to the upper end of the ALC wall panel 5 so as to fit in the center of the thickness of the ALC wall panel 5. At the position of the upper flange 2a of the horizontal beam 1, the flat bar 10 is inserted into the upright piece 2b of the ruler angle 2 via the hook 10a. Fixed. At the upper end of the flat bar 10, it is inserted into a slit-like hole 11c provided substantially at the center of a cap 11 having a substantially U-shaped cross section, and is fixed by welding from above.

Therefore, the load acting on the ALC wall panel 5, particularly the load acting on the upper end of the veranda, is reduced by the cap 11, the flat bar 10 having a substantially U-shaped cross section,
The load can be effectively transmitted from the ruler angle 2 to the horizontal beam 1 via the hook 10a. for that reason,
A large load does not act on the mounting portion at the lower end of the ALC wall panel 5, that is, the anchor steel bar 6 and the O bolt 7. Therefore, unlike the first or second conventional example, it is not necessary to previously provide a high-strength embedded nut or the like at an ALC wall panel manufacturing factory. In addition, anchor steel rod 6, O
Since the bolt 7, the rod-shaped member 12, and the like can all be installed at the construction site, the position of the mounting portion can be adjusted with respect to a deviation in dimension due to a site error in the position of the mounting portion.

Further, a cap 11 having a substantially U-shaped cross section is provided.
Is simply put on the flat bar 10 from above and welded from above, so that the work is simple and the attachment by welding can be ensured, so that the reliability is high. In addition, despite such a simple configuration, the cap 11 having a substantially U-shaped cross section has the brim portion 11b that comes into contact with the front and back surfaces of the ALC wall panel 5, so that the adjacent ALC wall panels are adjacent to each other. 5 can be restrained out of plane and integrated. Therefore, even when a large load is applied to a part of the ALC wall panel 5, it is possible not only to transmit the load to the flat bar 10 but also to effectively share the load with the adjacent ALC wall panels 5. .

Further, the brim portion 11b which comes into contact with the front and back surfaces
In the case of the ALC wall panel 5, even when the ALC wall panel 5 is warped, the effect of aligning the mutual surfaces and finishing the smoothness can be achieved at the same time. In addition, the mounting position of the flat bar 10 is the ALC wall panel 5.
And the flat bar 10 is not exposed on the back surface of the ALC wall panel 5. Therefore, when the waterproof finish of the veranda floor is performed, a depth of 10 to 20 m is directly provided on the back surface of the ALC wall panel to accommodate the waterproof edge.
It is possible to dig about m grooves. Therefore, the finishing work on the back surface can be saved, and the finishing thickness can be reduced, and the width of the unillustrated shelter to be accommodated in the upper part of the veranda wall can be reduced.

[0058]

Seventh Embodiment FIG. 7 is a seventh embodiment according to the present invention, and is a perspective view showing a mounting structure of an ALC wall panel and a perspective view of a special hardware. In this embodiment, similarly to the third embodiment, the lower part of the ALC wall panel 5 in the height direction is
And the fixing part B are both mounting parts by the rod-shaped member 12,
The fixing part A has the same structure. The fixing part A is provided at one position substantially at the center of the ALC wall panel 5 in the width direction, and the fixing part B is additionally provided on the left side in the width direction. For this reason, the strength of the entire lower part of the ALC wall panel 5 in the height direction is relatively low. However, as in the sixth embodiment, the flat bar 10 provided on the vertical joint between the ALC wall panels 5 is provided. Since the upper end of the ALC wall panel 5 can also be attached, compared to the third embodiment, the strength of the entire lower part of the ALC wall panel 5 in the height direction may be relatively low.

In this embodiment, in addition to the structure of the sixth embodiment, a bar-shaped member 12 having a plate-like base end 12a at the upper end is driven into the upper fore-face 5a of the ALC wall panel 5. The edge of the substantially flat portion 11a of the cap 11 is fixed by welding from above. Since the cap 11 is fixed to the ALC wall panel 5 via the bar-shaped member 12 as well as the flange 11b in this manner,
The load acting on the ALC wall panel 5 can be more reliably transmitted to the flat bar 10 and the horizontal beam 2 via the cap 11.

It is also possible to provide a plurality of protrusions on the bar-shaped portion of the bar-shaped member 12 to improve the degree of fixation to the ALC wall panel 5. When the upper surface position of the plate-like base end portion 12 a of the rod-shaped member 12 is provided substantially flush with the upper surface of the ALC wall panel 5, the substantially flat portion 11 a of the cap 11 is moved to the upper forefront surface of the ALC wall panel 5. Since it is provided so as to be in contact with 5a, it is preferable in terms of fitting.

In the seventh embodiment, the installation position of the rod-shaped member 12 provided on the upper edge surface 5a of the ALC wall panel 5 is 150 mm from the long side surface 5b of the ALC wall panel 5.
Was set as the position. A reinforcing bar (not shown) for reinforcing the ALC wall panel 5 is generally 50 mm from the long side surface 5b.
It is preferable that the rod-shaped member 12 is provided within a range where the reinforcing bar is provided in order to ensure the strength of the mounting portion by the rod-shaped member 12. In addition, the dimension from the upper edge surface 5a is about 30 mm, and the length dimension of the rod-shaped member 12 is from 75 mm to 20 mm.
If it is set to about 0 mm, it is possible to provide the bar-shaped member 12 within a range where the reinforcing steel is provided naturally.

[0062]

[Embodiment 8] Fig. 8 is an eighth embodiment according to the present invention, and is a perspective view showing a mounting structure of an ALC wall panel and a perspective view of a special hardware. In this embodiment, an O-bolt 7 provided at one location substantially at the center in the width direction with respect to one anchor steel rod 6 is provided as a mounting portion structure at the lower portion of the ALC wall panel 5 in the height direction. In this structure, a total of two O-bolts 7 are provided to be engaged with each other, that is, O-bolts 7 provided at one place on the right side of the vehicle. In this way, by using one anchor steel bar 6, it is possible to efficiently mount two O-bolts 7.

In this embodiment, in addition to the structure of the seventh embodiment, the plate-like base ends 12a of the adjacent rod-like members 12 provided on the upper part of the ALC wall panel 5 are connected to each other by the upper edge of the ALC wall panel 5. It is connected and fixed by a steel plate 13 disposed in contact with the surface 5a. The fixing method is welding fixing from above. Thus, the adjacent cap 11 is
2 and the steel plate 13 are continuously connected and fixed, so that a cap, not shown, or a cap with a handrail provided at a further upper portion of the ALC wall panel 5 can be attached to the cap 11 at an arbitrary position.
Alternatively, it can be fixed to the steel plate 13 by welding or the like.
In order to reliably perform welding, it is desirable that the cap 11 or the steel plate 13 has a plate thickness of 3.2 mm or more.

However, in the case of fixing a cap without handrail pillars, the cap support for fixing the cap is directly connected to the upper small face 5a of the ALC wall panel 5 by an ALC dedicated anchor or the like.
By fixing to the head, the cap can also be fixed.
In such a case, the thickness of the cap 11 or the steel plate 13 may be a thin plate such as 2.3 mm.
It should be noted that, in common with the sixth embodiment to the eighth embodiment, a groove (not shown) for accommodating the flat bar 10 is provided in advance on the long side of the ALC wall panel 5 at a factory or the like. In addition, processing of the ALC wall panel 5 at the construction site can be reduced. In addition, the vertical joints between the adjacent ALC wall panels 5 are easily provided in close contact with each other, and the inside of the veranda wall where the risk of intrusion of rainwater or the like is small is formed such that the vertical joints between the adjacent ALC wall panels 5 are close to each other. It is also possible to slightly reduce the casting and the like.

The dimensions of the flat bar 10 are the same as those of the sixth to eighth embodiments described above, in which the flat bar 10 is provided between all the vertical joints of the ALC wall panel 5. 1 for 2 to 3 wall panels 5
A flat bar 10 may be provided. However, ALC
In the case of a structure such as a veranda wall in which the upper end of the wall panel 5 is located at a height of about 1 m from the horizontal beam 1, a flat space is provided between all the vertical joints in order to secure a reliable mounting portion strength. Preferably, a bar 10 is provided.

In general, the dimensions of the flat bar 10 are suitably about 50 mm in width and about 9 mm in thickness, but depending on the conditions such as the interval at which the flat bar 10 is provided, the height of the veranda wall, and the height of the building. , Thickness 12mm, 16mm, 2
It may be as thick as 2 mm. Of course, the width of the flat bar 10 can be increased to 65 mm or the like.
The flat bar 10 is provided between the vertical joints of the ALC wall panel 5.
It is not necessary that all vertical joints have the same structure. For example, the vertical angles 10c shown in FIG. 1 and the like are provided at intervals of 1800 mm, which are three ALC wall panels 5 having a width of 600 mm. Hang 4 and 600
A structure in which a flat bar 10 of the type shown in FIG. 6 is provided at each vertical joint at mm intervals may be employed. That is, 180
In the vertical joint portions at 0 mm intervals, the vertical angle 10c shown in FIG. 1 and the like and the flat bar 10 of the type shown in FIG. 6 may be provided together.

In Examples 6 to 8, the ALC
Although the structure in which the size of the cap 11 provided on the uppermost part of the wall panel 5 is smaller than the width of the ALC wall panel 5 has been described, the cap 11 having a long dimension extending over three or more ALC wall panels 5 may be provided. Good. However, since the cap 11 having a long dimension is bulky and cumbersome in any of manufacturing, transportation, and construction, it is preferable that the cap 11 has a structure smaller than the width of the ALC wall panel 5.

Further, the ALC wall panel 5 is connected to the ALC wall panel 5 through the flat bar 10 provided at the vertical joint between the ALC wall panels 5.
The strength of the entire lower part of the ALC wall panel 5 in the height direction may be relatively low, and therefore, the hanging rib piece 8 may be used as the mounting bracket 8.
An example is shown in which one without a is used. In addition, what is common to all of Example 1 to Example 8 is that, as an example of the structure of the mounting portion, a structure configured at a construction site such as an anchor steel bar 6, an O-bolt 7, and a rod-shaped member 12 is shown as an example. However, it is needless to say that a structure using a hardware such as an embedding nut which is attached in advance at a manufacturing factory of the ALC wall panel 5 may be used.

[0069]

According to the first aspect of the present invention, the mounting strength at the lower portion in the height direction is not so small as to be lower than the mounting strength at the intermediate portion in the height direction of the ALC wall panel. It is possible to reinforce while adjusting by appropriately adding a mounting portion to both or either of the left and right side portions in the lateral width direction of the lower part.

The second invention of the present invention is that the ALC wall panel has a lower portion in the height direction than the fixed portion A provided at a substantially central portion in the lateral width direction of the ALC wall panel.
The fixing portion B provided at at least one of both or both of the left and right sides in the width direction of the wall panel is set to have a smaller mounting portion strength. By bearing the load and appropriately adding the fixing part B, the insufficient strength of the lower part in the height direction of the ALC wall panel can be compensated for while adjusting finely.

According to a third aspect of the present invention, a bar-like member having a plate-like base end at the lower end is driven into the lower edge face of the ALC wall panel as a lower mounting portion structure in the height direction of the ALC wall panel. Unlike the first and second conventional examples, the hanging rib pieces of the mounting bracket and the bolt heads of the bolts protrude toward the interior of the room unlike the first conventional example and the second conventional example, so that the ceiling material and the mounting metal are fixed. There is no problem that the hanging rib pieces and the bolt heads of the bolts interfere with each other and make the installation of the ceiling material difficult.

According to a fourth aspect of the present invention, as a mounting structure of a fixing portion B at a lower portion in a height direction of an ALC wall panel,
A simple structure in which a rod-shaped member having a plate-shaped base end at the lower end is driven into the lower edge surface of the ALC wall panel and welded and fixed to the receiving steel material is used. In comparison with the first or second conventional example, there is no need to previously bury an embedding nut or the like in an ALC wall panel manufacturing plant, and workability at a construction site is also good. Additional reinforcement is possible.

According to the fifth aspect of the present invention, since a vertical member (or a member obtained by processing a flat bar), which is a general-purpose member, is used as a vertical member passing between vertical joints of an ALC wall panel, loss of the member is reduced. In addition, the configuration can be simplified, and the cost can be reduced. Further, since the flat bar is contained within the thickness of the ALC wall panel, it is possible to save labor for finishing the inside. Further, a cap having a substantially U-shaped cross section is adjacent to the upper end of the flat bar.
Since it is fixed across the LC wall panel, it has the effect of dispersing the concentrated load to the left and right ALC wall panels, and at the same time, it can effectively transmit the load to the flat bar, and the ALC wall panel itself Even if warpage occurs, the effect of ensuring surface accuracy between the left and right ALC wall panels is exhibited. Further, there is no need to mount the cap on the upper edge of the ALC wall panel other than the flat bar, and the mounting structure can be easily constructed. In addition, since a large load does not act even in the middle or lower part of the ALC wall panel in the height direction, a high-strength embedding nut or the like is embedded in the middle or lower part of the ALC wall panel in the height direction in advance. There is no need to do so, and the mounting portion can have a relatively small structure. Further, the internal stress generated in the ALC wall panel itself can be reduced, and therefore, the amount of reinforcing reinforcing bars installed inside the ALC wall panel can be reduced.

In the sixth aspect of the present invention, the cap is provided with A
Since the plate-like base end at the upper end of the rod-shaped member driven into the upper foreface of the LC wall panel is fixed, the cap can be more reliably fixed to the upper foreface of the ALC wall panel. For this reason, even when the cap tree or the handrail with a handrail provided further above the ALC wall panel is fixed to the substantially flat portion, the cap tree or the handrail with the handrail can be firmly fixed without rattling. Further, a substantially flat portion of the cap is placed on the plate-like base end portion of the upper end portion of the rod-shaped member from above,
Further, it is possible to fix the upper end of the plate-like base end by a simple on-site operation in which the side edge of the substantially flat portion is welded from above.

In the seventh aspect of the present invention, adjacent plate-like base ends welded and fixed to the side edges of the adjacent caps are connected and fixed by a steel plate. Are fixedly connected. Therefore, it is possible to reliably fix the cap and the steel plate to the upper edge surface of the ALC wall panel. Therefore, it is possible to fix a cap or a handrail with a handrail provided further above the ALC wall panel at an arbitrary position with respect to the cap or the steel plate, and more securely fix the cap or the handrail with a handrail without rattling. I can do it.
