Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a panel fixture, and more specifically, a panel for the exterior wall of a building using a lightweight aerated concrete board cured with steam at high temperature and pressure, that is, a so-called ALC board. The present invention relates to panel fixtures that can be used particularly effectively in mounting methods.

(Prior Art) ALC boards have excellent properties such as lightness, heat insulation, and fire resistance, and have recently been widely used as exterior wall materials for buildings.

(Problems that the invention aims to solve) However, on the other hand, ALC boards also have the disadvantages of being brittle and easily damaged and having high water absorption, so when used as exterior wall materials, etc. There are problems such as water leakage from cracks due to deterioration over time, and countermeasures have been taken to counter this, such as creating grooves along the joints and filling them with waterproof sealing material in advance. However, it was not always effective.

By the way, in order to strengthen the fragility of the ALC board outer wall and block the infiltration of rainwater, etc.
It is effective to attach panels such as thin metal sheets to the outer wall surface of the ALC board using panel mounting brackets.

However, conventional panel mounting brackets were not designed specifically with ALC boards in mind as the mounting base for panels, so if these panel mounting brackets are used to attach panels to the outer wall of ALC boards, for example, ALC boards There were problems in that the support strength for the anchors for fixing the panel mounting brackets, which were driven into the panels, was insufficient, causing the panels to wobble and the joints between the panels to be incompletely blocked from rainwater, etc.

Therefore, the technical problem to be solved by the present invention is to provide a panel mounting tool that can sufficiently overcome the fragility and water absorption disadvantages of ALC boards when performing a panel installation method for ALC board external walls.

(Means for solving the problem) The technical means for solving the above problem consists of a panel mounting rail and a cover cap attached to this rail, and the rail is attached to the vertical direction of the outer wall of the ALC board. A channel member equipped with a pair of V-shaped inclined plate portions that follow the grooves provided in the direction joints, and a pair of flat wing plates provided along both sides of this channel member along the outer wall surface of the ALC board. A hole for driving an anchor is formed in the inclined plate portion of the channel member, and a flange for mounting a panel and a fin for fitting a cap are provided in parallel vertically in each of the pair of wing plates. , the groove between the flange and the fin is filled with sealing material.

(Function) A channel member is fitted into the vertical joint groove of the outer wall of the ALC board, and anchors are driven into the inclined surface portions of the pair of joint grooves through the holes provided in the inclined plate portions of the pair of channel members. Therefore, the anchors are driven from the pair of inclined plate portions along the directions that intersect with each other and obliquely to the outer wall surface of the ALC plate, so that they are difficult to come off and provide sufficient support strength from the ALC plate.

After the end of the panel is attached to the flange of the vane, a waterproof sealant is filled in the groove between the flange and the cap fitting fin, and the cap is attached to the panel mounting rail using the fin. By fitting, the joint portion of the panel is made waterproof and the water absorption of the ALC board is blocked.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 5.

The panel mounting rail 1 is a vertically elongated rail-like member, and along the center thereof, a channel member 2 recessed in the shape of a groove toward the back side is formed between the upper and lower ends of the panel mounting rail 1.

The channel member 2 is composed of a bottom plate portion 3 and a pair of inclined plate portions 4 that constitute walls on both sides of the channel member 2. It has a symmetrical inclination angle that forms a V-shape. This angle of inclination is set to a predetermined angle (for example, 45°) that follows the slope of the pair of grooves each having a V-shaped cross section provided at the vertical joint of the outer wall of the ALC board. Each of these inclined plate portions 4 is provided with holes 5 for driving anchors at predetermined intervals in the vertical direction.

Next, along the end of each inclined plate portion 4, a pair of vertically elongated vanes 6 are disposed between the upper and lower ends of the panel mounting rail 1.
are integrally extended outward. These vanes 6 are formed into flat plate shapes along the same plane. The tip of the wing plate 6 is raised toward the surface at a substantially right angle to form a flange 7 for mounting the panel, and this flange 7 is provided with screw holes 8 at appropriate intervals in the vertical direction. There is. Also,
From portions of the vane 6 closer to the inside than the flange 7, vertically elongated cap-fitting fins 9 protrude toward the surface side so as to be parallel to the flange 7, respectively. Therefore, a groove 9a for filling the sealing material is formed between the flange 7 and the fin 9. The pair of fins 9 have engagement protrusions 1 on the inner surfaces facing each other.
0.

Next, the cap 11 is a vertically elongated member with a U-shaped cross section that can cover the panel mounting rail 1 from the front side. A pair of locking fins 12 are longitudinally projected, and a protrusion 13 that can engage with the protrusion 10 is formed on the outer surface of these fins 12.

Next, install the above panel mounting rail 1 and cap 1.
The panel mounting method using 1 will be explained.

As shown in Fig. 2, mortar 15 is filled in the joints of ALC boards 14 that constitute the outer wall of a building, etc., and the cross section is V-shaped along the vertical joint of the outer wall. A joint groove 17 having a pair of inclined surface portions 16 is formed.

The channel member 2 of the panel mounting rail 1 is fitted into this joint groove 17. At this time, the pair of sloped surface portions 16 of the joint groove 17 and the pair of sloped plate portions 4 of the channel member 2 are formed to correspond to each other as described above, so that they come into surface contact. In this state, as shown in FIG. 3, fixing anchors 18 are driven perpendicularly to the sloped surface part 16 from the anchor driving holes 5 provided in the pair of sloped plate parts 4, and the panel mounting rails are 1 to the ALC board outer wall. Therefore, since the anchor 18 is driven obliquely to the direction in which the panel mounting rail 1 comes out (direction of arrow A in FIG. 3), it is difficult to come out. Also, since each anchor 18 is driven from the pair of inclined plate parts 4 along a direction that intersects with each other, the ALC that supports the anchor 18
Concentration of stress on specific parts of the plate 14 is avoided. From the above, even if the ALC board is a fragile material, sufficient support strength for the anchor 18 can be obtained, and there is no risk that the panel mounting rail 1 will wobble or come off from the wall surface.

Panel mounting rail 1 fixed in this way
Panels 19 made of rust-resistant thin metal sheets are attached to each pair of vanes 6 from both sides. This panel 19 is formed to have dimensions corresponding to the ALC board 14, and when installing it, the ALC
With the panel attached to the outer wall surface, the left and right ends are bent along the flanges 7 of the panel mounting rails 1 on both sides, and attached using screws 19a.

After the panel 19 is attached from both sides, the groove 9a between the flange 7 and the fin 9 is filled with a waterproof sealant 20, and then the cap 1
1 is applied from the front side. At this time, Finn 12
Since the fins 9 and fins 9 are engaged with each other through the meshing of the protrusions 10 and 13 with some elastic deformation,
The cap 11 is stably supported by the panel mounting rail 1. Further, the back surface of the cap 11 is in close contact with the sealing material 20 described above. From the above, the cap 11 and the sealing material 20 block rainwater and the like from entering from the outside.

The panel installation method described above is suitable for ALC of buildings.
This is done over the entire surface of the outer board wall.
At this time, since the panel 19 corresponds to the dimensions of the ALC board 14, the rails 1 and caps 11 are attached to each vertical joint of the ALC board 14 in the building 21, as shown in FIG. 19
while supporting the left and right ends of the panel 19 along the lateral joints 22 of the ALC board 14.
is formed.

At this horizontal seam 22, as shown in FIG.
Specified width (for example, 50 to 60 mm) with 9 facing up
The stacked panels 1 are assembled in a stacked manner, and grooves 23 are also provided in the horizontal joints of the ALC boards 14.
By folding 9 into the groove 23, the intrusion of rainwater etc. is prevented.

In addition, the upper edge of the rail 1 and the cap 11,
That is, as shown in FIG. 4, the openings at the upper end of the outer wall of the building 21 and the edges of the windows 24 are connected to the rail 1 and the cap as shown in FIG. 11 is covered to prevent infiltration of rainwater and the like.

In this embodiment, the rail 1 and the cap 11 may be formed using metal materials, as long as they have the necessary strength and formability.
For example, it may be formed using other types of materials such as synthetic resin.

Further, the inclination angle of the inclined plate portion 4 of the channel member 2 may be set to be larger or smaller than 45° as long as it follows the sloped surface portion of the groove of the vertical joint of the ALC board outer wall.

Furthermore, the fitting structure between the cap fitting fins 9 provided on the panel mounting rail 1 and the fins 12 on the cap 11 side can be replaced by any other fitting structure as long as the cap 11 is stably attached to the rail 1. A combined structure may also be adopted.

The panel installation method of this embodiment can be easily carried out when constructing an ALC board outer wall or as a renovation of an existing ALC board outer wall by simply forming a predetermined joint groove.

Next, another embodiment of the present invention will be described based on FIG.

In this embodiment, the cover plate portion 11b on the front side of the cap 11a is formed to have an arcuate cross section that bulges out to some extent toward the front side. Such a cap 11a deforms the cover plate part 11b into a bulge shape toward the surface side as shown by the imaginary line in the figure by pressing the side plate part 11c from the left and right sides (in the direction of arrow D in the figure). By Finn 1
2 inward to easily release the engagement state with the fins 9 on the panel mounting rail 1 side. That is, there is an effect that the cap 11a can be easily removed from the panel mounting rail 1.

The other aspects of the structure, construction method, operation, and effects of this embodiment are the same as those of the embodiment shown in FIGS. 1 to 5.

(Effects of the invention) The panel mounting tool of the present invention can obtain sufficient mounting strength for the panel when attaching the panel to the ALC board outer wall, so it can effectively reinforce the ALC board outer wall and also ensure that rainwater does not enter. to prevent
