Description

  The present invention relates to an attachment structure for attaching a wall panel to a housing, and more particularly to a ruler angle attachment method for attaching a lightweight cellular concrete panel to a housing.

In order to attach a lightweight aerated concrete (ALC) panel to a frame such as a steel beam, it is common to mount it through a ruler angle, and there are several methods for attaching the ruler angle to the frame. An example of a conventional ruler angle mounting method is shown in FIGS. FIG. 5 shows that the ruler angle 3 is placed on the upper surface of the steel beam 2 forming the housing and is directly fixed by welding. The portion 4 where the tip of the horizontal side 3a of the ruler angle 3 is in contact with the upper surface of the steel beam 2 is welded. The portion 5 where the back side of the horizontal side 3 is in contact with the top end of the steel beam 2 is welded.
FIG. 6 shows the ruler angle 3 placed on the upper surface of the steel beam 2 and fixed using a holding metal fitting. The horizontal side 3a of the ruler angle 3 is aligned with the ruler angle and the upper surface of the steel beam 2. It is fixed with a flat plate 6 which is a holding metal fitting formed in a lightning bolt shape, and the outer periphery of the flat plate 6 is welded to the ruler angle 3 and the steel beam 2 to fix the ruler angle 3 to the steel beam 2. (For example, refer to Patent Document 1).
In this manner, a lightweight cellular concrete panel (not shown) is fixed to a ruler angle fixed to the steel beam, and the lightweight cellular concrete panel is attached to the housing via the ruler angle.
Japanese Patent Laid-Open No. 09-111929

The ruler angle fixing method shown in FIG. 5 requires that welding be performed by installing a scaffold outside the building in order to weld the back side of the ruler angle in the field. Since the tip of the steel beam is welded, it is necessary to weld upward, so workability is poor, and there is a problem in ensuring the quality of welding.
The ruler angle fixing method shown in FIG. 6 is a method in which the flat plate is welded to the ruler angle and the upper surface of the steel beam, so there is no problem in workability, but the flat plate is placed on the indoor side of the upper surface of the steel beam. If a concrete slab, which is a floor, is formed on the upper surface of the steel beam, the flat plate may not be installed. Also, if the weight of the wall panel attached to the ruler angle is heavy, an excessive load will act on the ruler angle in the vertical direction, and if the flat plate is thin, the proof stress will be insufficient and the ruler angle will be sufficient for the steel beam. Since it cannot be fixed, it is necessary to increase the number of flat plate installation locations or to increase the thickness of the flat plate in order to fix it securely.

  With the above-mentioned method of fixing the ruler angle to the steel beam, the back side of the ruler angle and the tip of the steel beam are welded, so it is necessary to weld upward, so workability is poor, and when using a flat plate, it is fixed securely Therefore, it is necessary to increase the number of flat plate installation locations. Further, since the thickness of the flat plate has to be increased, there is a problem that workability and economy are deteriorated. Therefore, the present invention omits welding the back side of the ruler angle and the tip of the upper surface of the steel beam, and the ruler angle is improved in workability and economically by welding the mounting hardware only to the upper surface of the ruler angle and the upper surface of the steel beam. It is an object of the present invention to provide a method for fixing a weldable attachment and a wall panel to a frame through a ruler angle.

In order to solve the above-mentioned problems, the mounting hardware according to the present invention is a mounting hardware for mounting a wall panel to a housing via a ruler angle, and is made of an angle steel material having an L-shaped cross section, and is a lower part of one side of the angle steel material. It is characterized by having a notch only.
Further, the other mounting hardware according to the present invention is characterized in that the height of the notch is the same as the thickness of the horizontal side of the ruler angle, and the length of the notch is less than the width of the horizontal side of the ruler angle. Or the length of the notch is the same as the width of the horizontal side of the angle steel material.
The method for attaching a wall panel to a housing according to the present invention is such that a horizontal side of a ruler angle for attaching the wall panel is placed on the upper surface of a steel beam constituting the housing, and any one of claims 1 to 4 is provided. After fixing the horizontal side of the ruler angle at the notch of the mounting hardware using the mounting hardware described in the section, the horizontal side of the ruler angle and the mounting hardware are fixed by welding, and the mounting hardware and the steel beam The upper surface is fixed by welding.
Further, according to the present invention, when the horizontal side of the ruler angle and the mounting bracket are welded and fixed, the horizontal side of the ruler angle is parallel to the ruler angle of the mounting bracket. It is characterized in that it is fixed by welding with a gap between the sides, or it is characterized in that the horizontal side of the ruler angle and the side parallel to the ruler angle of the mounting hardware are in close contact and fixed by welding. It is.

  According to the mounting hardware according to the present invention, the ruler angle can be fixed by welding the mounting hardware and the ruler angle, and the upper surface of the mounting hardware and the steel beam. Since there is no need to weld, there is no need to weld upward from the outdoor scaffolding, and the workability is excellent. In addition, since the width and length of each side of the L-shaped mounting bracket are equivalent to the size of the ruler angle to be fixed, it has sufficient strength, so that a ruler like a flat plate as in the conventional method is used. When the weight of the wall panel to be fixed to the angle is large, there is no need to increase the installation location or the thickness in order to increase the mounting strength, and it is excellent in workability and economy. Moreover, since the mounting hardware is L-shaped in cross section and has the same width and length as the ruler angle, it is lightweight and has good workability.

Hereinafter, the present invention will be described based on specific embodiments with reference to the drawings, but the present invention is not limited to the embodiments.
FIG. 1A shows an external perspective view of the mounting hardware of the present invention. The mounting hardware 1 is composed of an angle steel material having an L-shaped cross section, and has a notch 9 for fixing a horizontal side of a ruler angle by sandwiching the horizontal side of the ruler angle between only one side 7 and the other side. Side 8 is not provided with a notch. The other side 8 is bent in a direction orthogonal to the side 7 having a notch 9.
The angle steel material constituting the ruler angle and the mounting hardware can be either an equilateral angle steel or an unequal angle iron.
The front view of the surface 7 which has the notch 9 of the attachment hardware 1 seen from the arrow direction of FIG. 1 is shown in FIG.1 (b). The width and length of each side of the mounting hardware 1 may be about the same as the size of the ruler angle to be fixed.
As for the dimensions of the notch 9, the length L need only be equal to or less than the depth L ′ of the side 7, it should be about the same as the width of the horizontal side of the ruler angle used, and the height H of the notch 9 is the horizontal of the ruler angle used. It may be equivalent to the thickness of the side.
Of course, the length L of the notch 9 may be the same as the depth L ′ of the side 7 as shown in an external perspective view in FIG. In this case, as shown in the front view seen from the direction of the arrow in FIG. 2A, the notch 9 is formed by cutting until the other side 18 of the mounting hardware 11 is reached, as shown in FIG. 2B. When this shape is adopted, the mounting is performed so that one side of the mounting hardware is in contact with the horizontal side of the ruler angle.

FIG. 3 is an external view showing an example of a method for fixing the ruler angle 3 to the steel beam 2 with the mounting hardware 1 of the present invention. The steel beam 2 uses H-shaped steel or I-shaped steel, forms a frame with the horizontal surface in the longitudinal direction facing upward, and mounts the ruler angle 3. The ruler angle 3 is placed on the plane of the steel beam with one surface of the angle steel material being horizontal, with the facet of the wall panel (not shown) to be attached facing down. The ruler angle 3 placed on the horizontal plane of the steel beam 2 is fixed by being sandwiched by the notch 9 of the mounting hardware 1, and the contact portion between the ruler angle 3 and the mounting hardware 1 and the contact portion between the mounting hardware 1 and the steel beam 2. The ruler angle 3 can be fixed to the steel beam 2 by welding.
In the example shown in FIG. 3, since the length of the notch 9 of the mounting hardware 1 is smaller than the width of one side of the ruler angle 3, the side 8 parallel to the ruler angle of the mounting hardware 1 is slightly separated from the ruler angle 3. At the position, it is fixed to the steel beam 2 by welding. The mounting hardware 1 can be welded and fixed to a horizontal side of a ruler angle or a steel beam at an arbitrary position as long as the situation in the field permits.

In the example shown in FIG. 4, the length of the notch of the mounting hardware is the same as the width of the horizontal side 3 a of the ruler angle, and the end surface of the side 7 having the notch of the mounting hardware 1 is in contact with the vertical piece 3 b of the ruler angle 3. By doing so, the joint surfaces of the two are welded to enable stronger welding and fixing.
More specifically, if the length L of the notch 9 shown in FIG. 2 is the same as the depth L ′ of the side where the notch of the mounting bracket is provided, the notch of the mounting hardware is provided as shown in FIG. It can be mounted on the steel beam 2 in such a way that the non-side 8 and the horizontal side 3a of the ruler angle 3 are in contact with each other, so that more firm fixation is possible.
