Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The invention relates to a mounting structure for exterior panels used for curtain oars, etc. that form the outer periphery of buildings, and is intended to facilitate the installation work. .

BACKGROUND ART Conventionally, in order to form an exterior with a panel, brackets attached to the four corners of the panel are fixed to fasteners or the like fixed to a building structural material. When fixing the bracket to the fastener, use bolts,
This is done using nuts, but since the installation work is done on a vertical surface, it must be done while supporting the panel.
Simply tightening bolts is also quite difficult. Furthermore, since four fasteners were provided on one panel on the building side, many construction steps were required, such as positioning them.

Problems to be Solved by the Invention The object of the invention is to provide a mounting structure for exterior panels that can be easily attached and fixed to the exterior of a building.

[Structure of the invention] Means for solving the problem The exterior panel used in the invention has a frame provided around the four peripheries of a rectangular surface plate, and a groove-shaped nut storage part that prevents nuts from rotating on the indoor side of the frame. is formed and Natsu is stored here. The bracket that fixes this exterior panel has a flat mounting part,
A pedestal on which the exterior panel is mounted is provided protruding from its surface, and a hole is provided in the mounting portion. The present invention is characterized in that the exterior panel is fixed to the bracket by tightening bolts through holes in the bracket onto nuts stored in the nut storage portions of the frame.

Function The bracket is fixed to the structure in advance.
As described above, the bracket of the present invention has a stand at the mounting portion, so when attaching an exterior panel, both ends of the exterior panel are placed on the respective bracket stands. Therefore, there is no need to hold and support the exterior panel by hand. The nut is housed in the frame so that it cannot rotate, but there are no particular restrictions on sliding, so if the position of the hole in the bracket and the position of the nut do not match when the panel is placed on the bracket base, You can adjust it by sliding it properly. Therefore, the bolt can be passed through the hole in the bracket and tightened to the nut in the nut receptacle of the frame. Since the nut is prevented from rotating as described above, there is no need to hold down the nut and it can be easily tightened with one hand.

Embodiment FIG. 1 shows a part of the exterior of a building obtained by the present invention, in which a large number of rectangular exterior panels 1 are installed in parallel. This exterior panel 1 has a cross-sectional shape shown in FIG. A front plate 3 and a back plate 4 are attached to both sides of a frame 2 which also serves as reinforcement of a panel formed from an extruded aluminum alloy material, and urethane foam 5 is filled and hardened between them. This frame body 2 is attached to each side of the rectangle, that is, to the four circumferences. In this embodiment, the structure includes a back plate 4 and urethane foam 5 in addition to the front plate 3 as described above, but a core material such as a honeycomb or a noncombustible board may also be used. , one that does not use a core material or the like may be used.

The frame body 2 has a surface plate support part 7 which is a flat surface perpendicular to the main wall 6 at the outdoor end of the main wall 6 which is substantially straight, and a primary packing at the tip which protrudes outward from the main wall 6 at the middle part thereof. Auxiliary wall 9 having support portion 8 and main wall 6
It has a cross-sectional shape having a back plate support part 10 having a flat surface perpendicular to the indoor end thereof, and a secondary packing support part 11 formed at the end thereof. Furthermore, a protrusion 12 protrudes from the secondary packing support part 11 toward the main wall 6 and a protrusion 1 from the main wall 6.
A groove-shaped nut accommodating portion is formed by the back plate support portion 10 and these projections. A rectangular nut 21 is accommodated in this nut accommodating portion as will be described later. Further, in this embodiment, a groove 14 is formed adjacent to the primary packing support portion 8, and this groove serves as a mounting portion for attaching a presser plate 33, which will be described later. A hole is made in the surface plate support part 7 of the frame 2 having this shape, and the stud bolt 15 attached to the surface plate 3 is tightened with a through-hole nut to fix the surface plate 3 to the frame 2. Further, the surface plate 3 and the surface plate support part 7 are further bonded with an adhesive, and urethane foam 5 is bonded between the two.
Prevents water leakage. On the other hand, since external forces such as wind pressure do not act on the back plate 4, there is no need to directly fix it to the frame. The back plate 4 is adhesively fixed to the urethane foam 5 by filling the space with a foaming liquid of urethane foam and curing the foam. At this time, it is desirable to fold the tip over the secondary packing support portion 11. Further, a butyl rubber sheet 17 is placed on the back plate 4 at a position corresponding to a bracket 16, which will be described later, in order to improve watertightness. In addition, in order to attach the panel 1 to the bracket 16, holes 18 penetrating the butyl rubber sheet 17, the back plate 4, and the back plate support part 10 are provided at the corners of the exterior panel of the nut storage section. It is open to 2. The nut 21 is fitted into this hole.

As shown in FIGS. 3 and 4, the panel 1 is
It is attached to the bracket 16 with a bolt 20 and a rectangular nut 21 stored in the aforementioned nut storage section. This bracket 16 is fixed to a fastener 19, which is made of two equilateral angle irons of appropriate length and mounted opposite each other on the structure. The bracket 16 is made of steel, and as shown in FIG.
and a mounting portion 23 formed in a planar shape at right angles thereto. Four holes 24 through which the bolts 20 are passed are formed at the four corners of the mounting portion 23. This hole 24 is made to be a long hole in the horizontal direction in order to accommodate dimensional errors in the panel 1, thermal expansion, displacement during earthquakes, etc. However, it is not necessary to make all four holes long holes on the right or left side. It is also possible to make only two long holes. If the height of the panel is large, the hole 18 in the frame 2 should be made horizontally long, and the holes 24a, 24a for fixing the lower side of the mounting part 23, that is, the upper end side of the panel, should be made as shown in FIG. It is desirable to have a vertically elongated hole. In this case, the upper holes 24b, 24
b does not have to be a long hole. An L-shaped stand 25 on which the end of the panel 1 is placed is attached by welding to a slightly upper side of the surface of the attachment part 23. A hole 26 for draining water is opened in the middle part of this stand.

The nut 21 is rectangular as shown in FIG. 6, and is inserted in advance into a nut accommodating portion formed by the projections 12, 13 of the frame body 2 and the back plate support portion 10 during panel fabrication. These nut accommodating parts are formed on the entire four circumferences of the frame, but they are placed at both corners of the frame, which become upper and lower when installed. Of course, since the nut 21 is movable, it may move during transportation, but it can be returned to a predetermined position during installation. The panel has bolts 20 through holes 24.
It is fixed by tightening it to the nut 21. The four corners of one panel are each fixed to separate brackets 16 as shown in FIG.

When attaching the exterior panel 1, it is sufficient to temporarily place its lower ends on the stands 25 of the respective brackets 16 to stabilize it, and then screw the bolts 20 into the nuts 21 through the holes 24 and 18. Since both ends of the panel 1 are placed on the stand 25 in this manner, the panel does not have to be supported even though the work is performed in a vertical position, and the work is simplified because it is only necessary to hold the panel. Furthermore, since the nut 21 is rectangular and is housed in a groove-shaped nut housing, there is no need to hold down the nut, and the bolt can be easily tightened with one hand. At that time, bolt 20
It is desirable to interpose a rubber washer in the washer 27 which has been bitten. Hole 1 in panel 1
As described above, even if there is a slight error in the position of 8, it can be adjusted using the elongated hole 24.

In this embodiment, when installing individual panels, packings 28, 30, 31 are placed vertically and horizontally between the primary and secondary packing supports 8, 11 provided on the frame 2 of adjacent panels to ensure watertightness. It is designed to be attached to. This packing 28 on the indoor side is almost the base 25 of the bracket 16 both vertically and horizontally.
The length should extend to near both ends of the line, and should not reach the intersection. Further, a seal 29 is filled between the packing 28 and the bracket 16. This gasket 28 is inserted and fixed between the secondary gasket support portions 11 of adjacent panels from the indoor side. On the other hand, the packings 30 and 31 attached between the primary packing support parts 8 and 8 have a length of 1.
Use a long one like that of a book, and the width 30 is approximately the length of panel 1. The intersection is shown in FIG. 7, where the tip of the packing 30 is notched except for the bottom 30a, and a seal 32 is filled between this notch and the packing 31. This intersection is reinforced by applying a presser plate 33 formed in a cross shape from the rear side. This presser plate 33 is inserted into the groove 14 formed adjacent to the primary packing support portion 8 of the frame body 2 and fixed therein. The cross-sectional shapes of these gaskets are not limited to those shown in the drawings, but may be any shape as long as they can be held between the respective gasket support parts.

As described above, the watertight structure of the packaging panel according to the present embodiment is constituted by the frame 2 around the panel and the packings 28, 30, and 31. That is, it has a double structure with the packing 28 on the indoor side and the packings 30 and 31 in the middle part. Since panel 1 is installed with spaced joints, the outdoor surface panels 3, 3
Although there is a gap between them, there is little rain that blows in from directly to the side, most of the rain that enters from an angle, and there is little that blows directly onto the gaskets 30 and 31, and rain that enters from between the surface plates 3 and 3. The groove formed between the surface plate support part 7 and the auxiliary wall 9 is used as a gutter and does not flow directly to the sealing part, and furthermore, of the rainwater that blows onto the wall surface, very little of it is blown onto the joint area, and most of it is on the surface plate. The water flows over the sprayed surface plate and does not flow directly into the seal, improving watertightness. Moreover, since there is a gasket 28 on the indoor side, there is nothing that can reach further inside. The gaskets 30 and 31 provide a watertight structure, but in this embodiment, the space between the auxiliary wall 9 and the back plate support 10 is opened to the outside air at the lowest end of the entire wall surface in order to further improve watertightness. It also serves as a drainage hole to introduce outside air into the space. As a result, the pressure in the space created between the auxiliary wall 9 and the back plate support 10 becomes equal to the wind pressure generated by the wind pressure, and rainwater is not sucked into this space due to the pressure difference between the inside and outside of the primary packing. There are very few things that can penetrate. In order to make the pressure in this space equal to the outside pressure, it is even better to make a hole in the auxiliary wall 9 of the lower frame 2 near the main wall 6.

Rainwater flows diagonally from between the surface plates 4 and 4 to the auxiliary wall 9.
However, those that enter through the vertical gap fall directly along the packing 31 or the auxiliary wall 9, and those that enter horizontally fall between the surface plate 7 and the auxiliary wall 9. Since the water flows through the gutter formed by the water and falls from both ends, it does not penetrate into the interior.

[Effects of the invention] As described above, in the present invention, since a stand is provided at the mounting part of the bracket, the exterior panel can be temporarily placed on the stand during the installation work of the exterior panel. The nut is stored in the nut storage part of the frame so that it does not rotate, and the bolt is tightened through the hole in the bracket through the nut, so you can hold the exterior panel with one hand and tighten it with one hand. be able to. That is, the present invention allows the exterior panel to be attached to the bracket easily and safely.

Furthermore, since the corners of the four exterior panels are fixed to one bracket, the number of brackets can be reduced and work efficiency can be improved.

Further, in the case of the embodiment, since both the front plate and the back plate are flat and there is nothing protruding from them, it is possible to stack the panels during conveyance, and it is possible to improve the conveyance efficiency.
