[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension member which does not move in response to thermal expansion and contraction of a coated metal envelope by seam welding and has a very simple structure.

[0002]

2. Description of the Related Art There has been a great deal of research and development on a coated metal enclosure which is seam-welded with a coated metal material (mainly a stainless steel material) on the inner and outer surfaces of a structure in a watertight and airtight manner.

[0003] In order to attach the rising portion of the coated metal material to the structure, a movable suspender having a tongue that can be appropriately moved according to the thermal expansion and contraction of the coated metal material has been often used.

[0004] This is because the thermal expansion and contraction responds to the thermal stress distortion of the coated metal material and thus the coated metal enclosure.

[0005]

The sliding type suspension has the disadvantage that the structure of the sliding portion of the tongue piece tends to be complicated, the number of manufacturing steps is increased, and the cost is high.

[0006]

Accordingly, the inventor of the present invention has conducted intensive studies to solve the above-mentioned problems. As a result, the present inventor has found that the present invention is directed to a vertical tongue piece and a bottom piece made of a substantially L-shaped metal sheet. And a reinforcing material covering the lower end of the tongue piece and substantially the entire bottom piece of the tongue piece, and the bottom piece of the tongue piece is provided at two locations in a direction substantially orthogonal to the tongue piece. By attaching a mounting hole, the tongue piece and the member serving as a reinforcing material are formed as a suspension having a mechanical strength larger than that of a metal plate material forming a coated metal material capable of being seam welded. It does not move in response to the thermal expansion and contraction of the metal enclosure and can be made extremely simple in structure, solving the above-mentioned problems and achieving the object.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

The present invention, as shown in FIG. 2, comprises a tongue piece 1 and a reinforcing member 2. First, the tongue piece 1 has a substantially L-shaped cross section. It is formed of a metal material that is a thin material, and more specifically, a stainless steel material is mainly used.

Further, the tongue piece 1 is composed of a tongue piece 1a and a bottom piece 1b, and the tongue piece 1a is perpendicular (including a substantially vertical shape) to the bottom piece 1b, and the tongue piece 1a and the bottom piece 1b are connected to each other. It has an L-shaped cross section.

The tongue piece 1 is made of spring steel or stainless steel in terms of strength, corrosion resistance, etc., and can be seam-welded to another metal plate, and maintains watertightness after welding. It is provided with conditions that can be used.

Further, the tongue piece 1 has durability against external forces such as a shear load and a bending load, and further, to improve mechanical strength such as tensile strength. Is subjected to a heat treatment to improve the properties of the metal.

There are various heat treatment means for improving the mechanical strength. One specific means is a precipitation hardening treatment.

Specifically, the load applied to the tongue piece 1 is, as shown in FIG. 1 and the like, a seam weld of an enclosure constructed by seam welding a plurality of coated metal members 5, 5,. This is the load applied when thermal expansion and contraction occurs along the longitudinal direction of the location.

The metal plate constituting the tongue piece 1 has a higher mechanical strength such as tensile strength and shear strength than the metal plate forming the coated metal 5.

Therefore, the load generated on the suspension A due to the thermal expansion and contraction occurring in the longitudinal direction of the seam welded portions of the adjacent coated metal members 5, 5 acts on the tongue piece 1 of the suspension A as a shear load and a bending load. In this case, the tongue piece 1a of the tongue piece body 1 can sufficiently withstand these loads.

As shown in FIGS. 2 and 3, the reinforcing member 2 has a flat piece 2a and a rising piece 2b formed from an edge of the flat piece 2a. The lower end of the tongue piece 1a of the tongue piece 1 and a bottom piece are provided. 1b is formed so as to cover substantially the whole, and is formed thicker than the thickness of the metal material forming the tongue piece body 1.

The flat piece 2a of the reinforcing member 2 is fixed to the bottom piece 1b of the tongue piece 1, and spot fixing is used as the fixing means.

The rising piece 2b of the reinforcing member 2 is fixed to the lower end of the tongue piece 1a of the tongue piece body 1.

The bottom piece 1b of the tongue piece 1 and the flat piece 2a of the reinforcing material 2 are provided with mounting holes 3 for fixing to the base portion 4.

As shown in FIG. 4, the mounting holes 3 are formed at at least two places, and the distance between the mounting holes 3 and 3 is constant.

As a specific example of the location where the mounting hole 3 is formed, as shown in FIG. 4, in a rectangular bottom piece 1b, the bottom piece 1b is opposed to the edge where the tongue piece 1a is formed. Two attachment holes 3 are formed in a line toward the end. That is, two mounting holes 3 and 3 are formed in the tongue piece 1a in a direction substantially orthogonal to the plan view.

As shown in FIG. 1, the coating metal material 5 is long in the longitudinal direction, and has side rising portions 5b, 5b formed on both sides in the width direction of the main plate 5a.

As shown in FIG. 2, when the adjacent covering metal members 5 and 5 are seam-welded in the longitudinal direction with the adjacent covering metal materials 5 and 5, the side rising portions 5b and 5b are opposed to each other.
These are seam welded to each other.

The members of the tongue piece 1 and the reinforcing member 2 are provided so as to have a higher mechanical strength than the metal plate material forming the covering metal material.

[0025]

The covering metal material 5 is placed on the upper or side of the base material 4 such as a steel frame or reinforced concrete, and at an appropriate interval in the longitudinal direction of the one side rising portion 5b, the present invention is provided. A large number of hooks A are fixed on the base material 4 (see FIG. 1).

When the hanging member A is fixed to the base material 4, fixing members 6, 6,... Such as drill screws and anchor bolts are used in the plurality of mounting holes 3 of the hanging member A.

Next, the adjacent coated metal material 5 is placed adjacent to the already mounted coated metal material 5, and the opposing side rising portions 5b, 5b are brought into contact with each other, and the opposing side is formed. Seam welding is performed while holding the tongue piece 1a of the hook A between the raised portions 5b.

A plurality of the hooks A of the present invention are arranged at predetermined intervals in the longitudinal direction of the seam welding portion of the envelope formed by the coated metal members 5, 5,.

[0029]

According to the present invention, a tongue piece 1 comprising a vertical tongue piece 1a and a bottom piece 1b formed of a substantially L-shaped thin metal plate, and a lower end of the tongue piece 1a of the tongue piece 1 are provided. The bottom piece 1 of the tongue piece 1 is composed of a reinforcing material 2 covering substantially the entire bottom piece 1b.
b, two mounting holes 3, 3 are formed in a direction substantially perpendicular to the tongue piece 1a to form a coated metal material 5 capable of seam welding the tongue piece body 1 and the reinforcing member 2. First, the covering metal material 5 is fixed to the base material 4 in the outer enclosure constituted by the covering metal materials 5 and 5 by using the suspension having a mechanical strength larger than that of the metal plate material. In addition, it can be very firmly fixed and can have extremely high durability after construction, and secondly, it can be provided at a low price with a very simple structure. It works.

These effects will be described in detail. The metal plate of the tongue piece 1 forming the hook A of the present invention has a higher tensile strength, shear strength, etc. than the metal plate forming the coated metal 5. Since the mechanical strength of the armature A is increased, thermal expansion and contraction due to the outside air occurs at the seam welded portions of the adjacent coated metal members 5 and 5, and a tensile force and a shear force act on the tongue piece 1a of the hook A. In this case, since the tongue piece 1 of the hanging member A is sufficiently within its strength against the tensile force and the shearing force, the hanging member A is a completely fixed type and is not a slide type. Nevertheless, an extremely strong attachment can be achieved (see FIG. 5).

Next, in the hook A of the present invention, a tongue piece 1 composed of a tongue piece 1a and a bottom piece 1b, and a reinforcing material 2 covering substantially the entire lower end of the tongue piece 1a and the bottom piece 1b of the tongue piece 1 Since two mounting holes 3 and 3 are formed in the bottom piece 1b of the tongue piece body 1 in a direction substantially perpendicular to the tongue piece 1a, the bottom piece 1b of the hook A is Even if a rotational moment is applied to the tongue piece body 1 at the center, the suspension A is fixed to the mounting holes 3, 3,. By fixing to the base part 4,
Not only can it sufficiently cope with the rotational moment in terms of strength, but also because the bottom piece 1b is strongly reinforced by the reinforcing material 2, the mounting holes 3, 3,
. And the fasteners 6, 6,... Can be prevented from being cracked.

In the present invention, the bottom piece 1b of the tongue piece 1
Since the two mounting holes 3 and 3 are formed in a direction substantially perpendicular to the tongue 1a, not only can the tongue 1a be made strong, but also the width can be increased in the width direction. There is an effect that the strength can be safely secured by fixing the mounting holes 3 and 3 at the locations.

Next, since the suspension A of the present invention is formed by bending a metal plate into an L shape and fixing the reinforcing member 2 to the bottom piece 1b, the present invention is compared with a slide type suspension. And the structure is extremely simple, suitable for mass production also in its manufacture, and can be provided at a low price.
