Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a structure for attaching and holding an exterior panel to a building wall such as a lightweight aerated concrete panel.

(Prior Art and Problems) Various mounting and holding structures have been proposed for attaching exterior panels to building walls, such as PC wall panels. For example, a method of installing by applying binder, cement mortar, adhesive, etc. between the back of the exterior board and the surface of the building wall, or a method of installing by installing a mounting base material on the surface of the building wall and fixing the mounting brackets etc. to this mounting base material. There are construction methods etc.

Each of these construction methods has its own advantages and disadvantages; mounting structures using binders, cement mortar, etc. do not provide sufficient mounting strength when the exterior panels themselves are enlarged, and highly skilled workers are required to maintain a constant construction accuracy. It takes. Furthermore, the method of fixing with a mounting base material also has many problems in terms of construction and cost, such as requiring high construction accuracy to ensure the horizontal and vertical accuracy of the mounting base material itself.

(Means for solving the problems) This invention was devised in view of the above problems.
A wide vertical groove is formed in advance on the surface of the building wall, and upper, middle, and lower holding fittings are fixed in the vertical direction within the wide vertical groove, and these holding fittings are used to hold the parts at the corresponding positions. The upper exterior plate, middle exterior plate, and lower exterior plate are held and installed.

In other words, by fixing each holding fitting in the wide vertical groove formed on the surface of the building wall, it is possible to eliminate the gap between the building wall surface and the exterior plate, and each holding fitting in the wide vertical groove can be fixed. It is possible to maintain the mounting accuracy of the metal fittings at a constant level.

(Example) The mounting structure of the present invention will be explained in detail below based on the drawings.

1 to 3 are perspective views of a holding fitting used in the mounting structure of the present invention.

FIG. 1 shows a lower holding fitting 1 fixed to the lower part of a building wall. This holding fitting 1 is formed by a mounting part 11 having a square cross section, a mounting part 12 extending substantially orthogonally from the lower end of the mounting part 11, and a claw piece 13 bent upward from the mounting part 12. be. The reason why the mounting portion 11 is formed to have a substantially square cross section is to increase the effective cross section and ensure the retention of the exterior plate. Further, the mounting portion 12 extends approximately equal to the thickness of the exterior plate, and the claw pieces 13 are provided to prevent the exterior plate from easily coming off the mounting portion 12. Furthermore, a required number of rivet holes 14, 14 are bored approximately in the center of the mounting portion 11.

FIG. 2 shows a middle part holding fitting 2 that holds the upper and lower ends of the middle part exterior plate. The cross section of this middle part holding fitting 2 is also
The mounting portion 21 has a shaped mounting portion 21, and a pair of upper and lower mounting portions 22 and 23 are formed by cutting and raising approximately the center of the mounting portion 21. Further, claw pieces 24 and 25 are formed at the tips of each of the upper mounting part 22 and the lower mounting part 23, respectively. The sizes of these upper parts 22 and 23 and the functions of the claw pieces 24 and 25 are the same as those of the lower holding metal fitting 1 described above.
It is similar to Furthermore, a required number of rivet holes 26, 26, . . . are similarly drilled in the center of the mounting portion 21.

FIG. 3 shows an upper holding fitting 3 that holds an exterior panel at the top of a building wall. This upper holding fitting 3 includes a mounting portion 31 having a substantially square cross section and a mounting portion 3
A pair of holding sides 32, 32 are cut and raised at the center of the upper part of 1, and an insertion side 33 is formed within these holding sides 32, 32.
is inserted, the mounting part 34 is integrally extended from the insertion side 33, the tip of the mounting part 34 is bent downward, and the claw piece 35 is inserted.
was formed.

Using each of the above-mentioned holding fittings 1, 2, and 3, the building wall 4
We will explain the specific construction of attaching exterior panels to the.

FIG. 4 is a partially omitted perspective view of the state in which the holding fittings 1, 2, 3 are fixed to the building wall 4, and the exterior plates 5, 5... are attached by the holding fittings 1, 2, 3. FIG. 5 is a longitudinal sectional view with the same part omitted.

In other words, the building wall 4 has wide vertical grooves 4 at required intervals.
1, 41... are formed. Wide vertical groove 41,
The depth of 41 is approximately equal to the thickness of each of the holding fittings 1, 2, and 3 so that the holding fittings 1, 2, and 3 do not protrude from the surface of the building wall. A lower holding fitting 1 is fixed to the lowermost end of the wide longitudinal groove 41 in order to hold the lower end 51a of the lower exterior plate 51. The exterior plate 5 is usually made of a glass plate, a synthetic resin plate, a ceramic plate, etc., and has a size of about 600 x 600 mm. The lower holding fitting 1 is inserted into the rivet hole 1 in the anchor plate 6 which is buried in the building wall 4 in advance.
Drive in rivets 7 and 7 from 4 and 14. Thereby, the lower holding fitting 1 is securely fixed to the building wall 4. Moreover, if the surface smoothness of the wide vertical grooves 41, 41 is ensured, the lower holding fitting 1 will always be fixed to the building wall 4 while maintaining a predetermined distance therebetween. The lower end 51a of the lower exterior plate 51 is placed on the mounting portion 12 of the fixed lower holding fitting 1. Next, the upper end 51b of the lower exterior plate 51 is attached to the lower part 23 of the middle holding fitting 2.
In the state in which it is held, rivets 7 are driven into the anchor plate 6 in the same manner as described above to fix the middle part holding fitting 2 to the building wall 4. Then, the lower end 52a of the middle part exterior plate 52 is placed on the upper mounting part 22 of the middle part holding fitting 2. Note that the mounting portion 12 of the lower holding fitting 1 and the lower mounting portion 23 of the middle holding fitting 2 have an interval equal to the height of the exterior plate 5. Thereafter, the middle exterior panels 51, 51, . Then, by inserting the insertion side 33 into the holding sides 32, 32, the upper end 5 of the exterior plate 53
3b is held by a mounting portion 34.

In the above explanation, the lower exterior plate 51 and the middle exterior plate 5
2, 52...Although the explanation has been made regarding the state in which the upper exterior plates 53 are held in a vertical line, the present mounting structure is not limited to this mounting construction, and there is a method for holding the exterior plates 5, 5 adjacent to each other in the wide vertical groove 41. It is also possible to fix the holding fittings 1, 2, 3 and attach the exterior plates 5, 5, . . . in the row direction (see FIG. 4).

(Effects) As explained above, the mounting structure of the building exterior board of the present invention mechanically achieves the consistency of the joints and the smoothness of the exterior board surface, resulting in high construction accuracy without the need for highly skilled craftsmen. Also, the construction period can be shortened.

Further, as the mounting member, a holding metal fitting is formed in advance and is fixed to the surface of the building wall in such a manner that it does not protrude, so that it does not get in the way when the building wall is being transported, improving workability.
