Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight aerated concrete (hereinafter referred to as "ALC") panel for an outer wall which is attached to a steel frame of a building to form an outer wall, and a method of attaching the outer wall panel, and particularly to an adjacent structure. The present invention relates to an ALC panel for an outer wall suitable for construction in a narrow building site where temporary construction of a construction scaffold is difficult due to a small gap between the ALC panel and a construction method of the ALC panel.

[0002]

2. Description of the Related Art Conventionally, when an ALC panel is attached to a steel frame of a building to form an outer wall, various construction methods are implemented, for example, a dry construction method as shown in FIG. This method is 600mm wide, 2400-3000mm long,
Holes 1b and 1b 'are drilled from the long side edge near the upper and lower ends of the ALC panel 1 having a thickness of about 100 mm toward the center to embed the anchors 7 and 7', respectively. Also, holes 1a, 1a 'orthogonal to the anchors 7, 7' from the back of the panel.
And a weight receiving metal fitting 7 is screwed to the anchor 7 and 7 'at the lower end with bolts 6 and 6', respectively.

On the other hand, horizontal portions 3b, 3b 'of ruler angles 3, 3' are fixed to desired positions on the upper and lower horizontal beams 2, 2 'of the frame. Then, the self-weight receiving metal fitting 7 of the ALC panel 1 and the snap fastener 5 are fixed to the vertical portions 3a, 3a 'of the upper and lower ruler angles 3, 3', respectively. Next, the ALC panel 1 of the same level is sequentially attached adjacent to the ALC panel 1, and the ALC panel 1 of the upper stage is similarly mounted.
Attach. Thereafter, a bar-shaped backup material 8 such as styrene foam is fitted into the vertical joint seal groove 1c from the outside, and the outside thereof is filled with a sealing material 9.

[0004] The horizontal joints at the upper and lower ends of the ALC panel 1 are as follows:
When the upper ALC panel 1 is attached, a fireproof joint material 10 such as rock wool is sandwiched as shown in FIG. 7, and then a backup material 8 is inserted from the outside, and a sealing material 9 is filled on the outside. Thereafter, the entire outer wall surface is painted and finished to form an outer wall surface having excellent appearance and earthquake resistance. In this method, the ALC panel mounting work can be performed from the indoor side, but the filling of the sealing material and the painting work are performed using a temporary scaffold outdoors.

[0005] However, since the gap between adjacent structures is narrow, work from the outdoor side cannot be performed on a narrow building site where temporary construction of construction scaffolds is difficult.
Each time one ALC panel is attached, a worker must lean out from the indoor side and perform the work of filling the backup material and the sealing material using the C panel.
Therefore, not only is it troublesome, but also the accuracy of finishing such as a waterproof function tends to be unstable.

In place of filling the above-mentioned backup material or sealing material, a specially shaped rubber gasket is attached in advance to two to four places on the small face of an ALC panel whose surface has been painted at a factory. There is also a construction method in which an ALC panel is attached to a frame and the gasket is used as a joint seal. However, this method has a problem that not only is a rubber gasket of a special shape expensive, but also the processing of the ALC panel small face and the drainage structure of the joint become complicated, resulting in increased labor and cost.

[0007]

SUMMARY OF THE INVENTION In the present invention, when an ALC panel is attached to a steel frame of a building to form an outer wall, the gap between adjacent structures is narrow, so that temporary installation of a construction scaffold is difficult. It is an object of the present invention to provide a structure of an ALC panel for an outer wall and a method of mounting the ALC panel which can be easily constructed at a relatively low cost even at a construction site.

[0008]

In order to achieve the above object, an ALC panel for an outer wall according to the present invention comprises a seal groove provided on a long side edge on both sides of an ALC panel and an adjoining short side edge on both sides. A stick-like elastic body having waterproofness and having a thickness slightly thicker than the depth of the seal groove is stuck to a stick-shaped elastic body over a position facing the ALC panel.

Further, the method of mounting an ALC panel according to the present invention is a method of forming an outer wall by mounting the ALC panel to a steel frame with a mounting bracket, wherein seals are provided on both sides of the ALC panel on the long side of the small side. Over the groove and the position opposite to the adjacent ALC panel on the short side face on both sides,
After sticking back-up material which is a rod-shaped elastic body and the thickness is slightly thicker than the depth of the seal groove in advance, paints the surface of the ALC panel, and then attaches the adjacent ALC panel to the ALC panel when attaching the ALC panel to the frame. The backing materials of the panels are mounted so as to be in elastic contact with each other. Preferably, each time one ALC panel is mounted on a frame, a sealing material is filled outside the backing material. .

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION An ALC panel for an outer wall according to the present invention opposes a seal groove previously provided at both sides of the ALC panel at the factory and a panel adjacent to the both sides at the short side. At the construction site, this ALC is used at the construction site because a stick-like elastic material with a waterproof property and a thickness slightly thicker than the depth of the seal groove are stuck over the position.
If the panel is attached to the frame as in the prior art and the refractory joints are inserted into the horizontal joints, the backup members at the vertical and horizontal joints of the adjacent ALC panels elastically contact to form an integral backup member. If the surface of the ALC panel is pre-painted or an anchor is buried in advance, it is only necessary to fill the joint with a sealing material, so that the work can be further facilitated, the construction period can be shortened, and the waterproofness can be improved. And an outer wall having high appearance can be formed. Furthermore, construction can be performed even in a narrow building site where temporary construction of a scaffold is difficult.

The material of the backup material may be foamed rubber, foamed synthetic resin, soft rubber, hollow rubber, or the like. If the shape is small and rod-shaped, it may be a combination of square, stepped, semi-cylindrical, etc. The ALC panel can be used as appropriate, and the ALC panel does not need to be specially processed.
It is cheaper than LC panels.

In the method of mounting an ALC panel according to the present invention, the seal groove provided on the long side edge of the ALC panel on both sides and the positions of the upper and lower short side edges facing the adjacent ALC panel. In addition, since the surface is painted after sticking a waterproof and rod-shaped elastic backing material, it is not necessary to attach or detach the masking of the small face, which can save labor and cost. When attaching this ALC panel to the frame, fireproof joints are inserted into the horizontal joints and each adjacent A
The LC panel is attached so that the backup material attached to the long side and the short side of the LC panel elastically contact each other.

At this time, every time one ALC panel is attached,
If a sealing material is filled from the inside of the building to the outside of the backup material, temporary installation of a scaffold outdoors is unnecessary. Therefore, construction can be performed even in a narrow building site, and the number and cost of attaching and detaching a scaffold can be reduced. Each adjacent AL
Since the backup material at the joint of the C panel is in elastic contact with the joint, the joint is highly waterproof, so that filling of the sealing material may be omitted depending on the location.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing one end in the longitudinal direction of the ALC panel of the present invention, FIG. 2 is a view showing a fore face of the ALC panel, (A) is a sectional view of a long side fore face, and (B) is a sectional view. It is sectional drawing of a short side small-mouthed surface. The conventional ALC panel 1 is provided with joint sealing grooves 1c having a depth of 5 mm at positions 21 mm from the surface of the ALC on the long sides of the small sides on both sides thereof. , A backup material 11 is stuck over the entire length. The surface 1e of the ALC panel 1 and its edges are coated in advance with a moisture-permeable and waterproof paint.

The backup material 11 is a rod-shaped butyl rubber having a rectangular cross section with a thickness of 8 and a width of 10 mm as shown in FIG. 5 (A), and the surface of the backup material 11 having a thickness of 8 mm is a joint seal of the ALC panel 1. It is bonded to the side surface of the groove 1c. The above-mentioned anchor 7 is embedded near both ends in the longitudinal direction of the ALC panel 1.

The anchor 7 is buried by piercing 1a. An adhesive material is applied to one surface of the backup material 11 having the same material and dimensions as described above and having a width of 10 mm, and a release paper (not shown) is used.
Is stuck.

The backup material 11 is used for the ALC panel 1
In order to adhere to all the fore-faces of the ALC panel 1, the joint seal groove 1c on the long-side fore-face on both sides of the ALC panel 1 while peeling the release paper
Then, adhesive is applied over the entire length of each short side edge 1d on both sides with an adhesive, and the remainder is cut. Thereafter, the surface 1e and its edges are ground-coated and then finish-coated with a desired paint.
At this time, since the backup material 11 is adhered to each of the fore-edge faces, there is no need to mask the remaining fore-edge faces.
The anchor 7 may be buried immediately before the ALC panel is attached, if necessary.

The ALC panel 1 thus processed is
In order to attach the scaffold to the skeleton at the site where temporary installation is difficult, first, the self-weight receiving bracket 4 and the snapper-type metal fitting 5 are screwed to the back surface of the ALC panel 1 with bolts 6 as in the above-described conventional example. Next, as shown in FIGS. 3 and 4, the self-weight receiving bracket 4 of the ALC panel and the snapper-type metal fitting 5 suspended in a vertical position are fixed to a desired position of the ruler angle 3 of the frame. Similarly, the next ALC panel is mounted, but at this time, the back-up materials 11 on the left and right long sides and the short sides on the upper and lower sides are brought into close contact with each other so as to elastically contact each other.

On the back side of the short side small face, a fireproof jointing material 10 is provided.
Is inserted. Then, each time one ALC panel 1 is attached, the sealing material 9 is filled outside the backup material 11 at the vertical and horizontal joints. The outer wall surface can be formed by repeating the same operation, and according to this method, ALC
Both panel installation and finishing work can be performed indoors, so there is no need for temporary scaffolding. The backup material 11 at the vertical and horizontal joints is elastically contacted and has a high waterproof property, so that the filling of the sealing material 9 can be omitted depending on the place.

At this time, an adhesive is applied to at least the other surface of the backup material 11 having a width of 10 mm, that is, the side facing the outer surface, and a release paper is attached thereto.
After the panels are attached, the release paper may be pulled out and the backup material of the adjacent ALC panel which is in elastic contact with the panel may be adhered. It is preferable to use a sealing material having a color tone similar to that of the coating of the ALC panel 1 because the appearance is improved.

FIG. 5 shows the shape of the backup material.

Etc., and any material can be used as long as it has elasticity, waterproofness, and weather resistance. The dimensions and the like can be appropriately selected as needed. In this embodiment, the construction method in a narrow building site where temporary installation of a scaffold is difficult has been described. However, if a scaffold is provided, the efficiency of ALC panel installation work is increased, and the sealing material is filled after the ALC panel is completely attached. Needless to say, the workability can be further improved because it can be painted or painted.

[0021]

As described above, according to the present invention, the seal groove previously provided on the long side edge of the ALC panel at the factory and the position of the short side edge facing the adjacent ALC panel at the factory. Since the backing material is sticking with a stick-like elastic body with a waterproof property and the thickness is slightly thicker than the depth of the seal groove, the ALC panel is attached to the skeleton as in the past at the construction site, If the refractory joint material is inserted into the horizontal joint, the backup materials of the vertical and horizontal joints of the adjacent ALC panels are elastically contacted to form an integrated backup. If the ALC panel is pre-finished or an anchor is buried in advance, it is only necessary to fill the joint with a sealing material, so that the work can be further facilitated, the construction period can be shortened, and the waterproofness is high. An outer wall with an excellent appearance can be formed, and construction can be performed even in a narrow building site where it is difficult to temporarily provide a scaffold.

Further, in the method of the present invention, the waterproof property is provided in advance over the seal grooves provided on the long sides of the long sides of the ALC panel and the positions of the upper and lower short sides facing the adjacent ALC panels. Since the surface is painted after sticking an elastic backup material in a stick shape, it is not necessary to attach and detach the masking of the small face, which saves labor and cost, and this A
When attaching the LC panel to the frame, a refractory joint is inserted into the horizontal joint, and attached so that the backup material attached to the long side and short side of the adjacent ALC panel is elastically contacted. . At this time, every time one ALC panel is attached, if a sealing material is filled from the inside of the building to the outside of the backup material, temporary installation of a scaffold outdoors is unnecessary. Therefore, construction can be performed even in a narrow building site, and the number and cost of attaching and detaching a scaffold can be reduced. In addition, since the backup material at the joints of the adjacent ALC panels is in elastic contact with the joints, the joints have high waterproofness, so that the filling of the sealing material can be omitted in some places, so that the cost is reduced.
