Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a structure for attaching corner members to corners of an outer wall in an outer wall structure using concrete panels such as lightweight aerated concrete.

Conventional technology Conventionally, when external wall panels produced in a factory are transported to a site and fixed to a frame, the corners of the external wall are constructed by joining the external wall panels at right angles to each other, and the corner members are not used. It has not been done.

The problem that the invention attempts to solve Generally, the so-called autoclave-cured
ALC boards have the advantage of being lightweight and have excellent fire resistance, but on the other hand, they have the disadvantage of being easily chipped. Therefore, when external wall panels made of such ALC boards are joined to each other at the corner portions as described above, there is a drawback that the corner portions are easily chipped.

This invention aims to eliminate such conventional drawbacks by installing corner members made of concrete in the corner spaces, and to provide a structure that allows such corner members to be installed simply, efficiently, and reliably. It was made for the purpose of

Means for Solving the Problems In order to achieve the above object, in this invention, there is a gap between the end face of an external wall panel made of a concrete plate and the end of an external wall panel made of another concrete plate in a direction perpendicular to the external wall panel. In the space of the protruding corner that is formed, the end portions of the frame supporting these external wall panels are extended toward each end surface side, and
A supporting metal fitting in which fixing pieces are formed by bending both ends of the plate-shaped main body diagonally to the same side is fixed to the frame extension part and installed across between the frames. A mounting bolt is inserted into a bolt hole formed in the main body of the body, and the tip of the mounting bolt is passed through the bolt hole of a concrete corner member that fills the space to support the corner member. It is characterized in that the outer surface of the panel is a circumferential portion that is continuous with the outer surface of the outer wall panel.

Embodiment Hereinafter, the structure of this invention will be explained based on the illustrated embodiment. FIG. 4 shows an example of a building using the above-mentioned corner member.
It is constructed of lightweight aerated concrete panels made of ALC boards, and corner members 4 made of precast concrete such as ordinary concrete are used at the corners of the bookstore 2 and the corners of the balcony 3.

FIG. 1 shows the mounting structure of the corner member 4 on the balcony 3 portion. In the figure, 5 is an exterior wall panel that constitutes the side wall of the balcony;
is an exterior wall panel that also constitutes the front wall,
The ends of these outer wall panels 5 and 6, which are arranged at right angles to each other, are not joined to each other, and have a space 7 between the end faces 5a and 6a. 8,8
Although the detailed structure is not shown, it is a vertical frame arranged vertically to support each of the outer wall panels 5 and 6, and one side 9 of the frame is in contact with the back surface of each of the outer wall panels 5 and 6. , these outer wall panels 5 and 6 are supported by bolt members (not shown) or the like. Both frames 8, 8 have an L-shaped cross section, and the other side 10 extends along the end surfaces 5a, 6a of the respective outer wall panels 5, 6.

As shown in FIG. 3, reference numeral 11 is a support metal fitting made by bending both ends of a main body 12 made of a band-shaped metal plate in an inclined direction toward the same side surface to form fixing pieces 13, 13. A bolt hole 14 is formed. This support fitting 11 is connected to the fixed piece 1
As shown in FIG. It can be installed in a straddling manner.

As mentioned above, the corner member 4 is made of a precast concrete material such as ordinary concrete, and as shown in FIG.
It is formed to have a fan-shaped cross section consisting of flat parts 14, 14 and a circumferential part 15 so as to fit approximately into the housing. Recessed recesses 16 are formed at appropriate intervals in the vertical direction at the ends of the sides where the flat parts 14, 14 intersect with each other, and the bottoms 16a of the recessed recesses 16 are flat, A bolt hole 17 is formed penetrating from the center toward the circumferential portion 15 side. Furthermore, a recess 18 is formed around the bolt hole on the circumferential portion 15 side, as shown in FIG.

The corner member 4 formed as described above is inserted into the space 7 with the circumferential portion 15 located on the outside. A spacer 19 made of a foam material or the like is interposed between the outer surface of the holder 11 and the outer surface of the holder 11 . On the other hand, in the support fitting 11, a support bolt 20 is inserted into a bolt hole 14 at the center of the main body part 12 and protrudes outward. The tip of this bolt 20 is inserted into the bolt hole 17 formed in the spacer 19 and the corner member 4, and the nut 21 is screwed into the recess 18 on the circumferential portion 15 side to tighten and fix the corner member 4. ing.

Reference numeral 22 in FIG. 1 is a filler inserted into the gap between each corner member 1 and the end surfaces 5a, 6a of the outer wall panels 5, 6. This filler 22 is made of a flexible material such as a sponge material. This absorbs the error in the gap between the corner member 4 and the outer wall panels 5, 6 during installation, and in the event of an earthquake, the outer wall panels 5, 6 and the corner member 4 are Absorbs vibration differences to prevent damage. Also, a caulking material 23 is placed on the outside of this filler 22.
23 is packed.

Effects of the invention As described above, according to this invention, a concrete corner member is installed in the corner space between external wall panels made of concrete plates, and the outer surface of this corner member is continuous with the outer surface of the outer wall panel. Since the circumferential part is shaped so that there are no sharp edges, there are no sharp edges at the corners, and even when using ALC exterior wall panels that are prone to chipping, it is possible to obtain a structure with relatively little chipping. . Furthermore, in the present invention, both ends of the support fitting are bent diagonally to form a fixing piece, and this fixing piece is fixed to the end face of the outer wall panel, so that the main body between these fixing pieces is aligned with the bolt insertion direction. By being arranged at right angles, the head of the bolt or the bearing surface of the nut reliably abuts against the flat surface, making it easy and reliable to tighten the bolt.
