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 Covered metal enclosures that are seam-welded with a coated metal material (mainly stainless steel) on the inner and outer surfaces of a structure to perform watertight and airtight construction have been actively researched and developed.

[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.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

The present invention, as shown in FIG. 2, comprises a tongue piece 1 and a reinforcing material 2. First, the tongue piece 1 is formed of a substantially L-shaped thin metal plate. The tongue 1a is perpendicular (including a substantially vertical shape) to the bottom 1b.

The tongue piece 1 is formed by appropriately bending a thin metal plate. The tongue piece 1 is bent to either side from the lower end of the tongue piece 1a to form a bottom piece 1b. There are also embodiments in which the bottom piece 1b is formed in a substantially L shape or the lower end of the tongue piece 1a is alternately bent from both sides substantially from the middle.

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 furthermore, a metal material forming the tongue piece 1 in order to improve the mechanical strength. Is subjected to heat treatment.

Although there are various heat treatment means, one specific example thereof is by a precipitation hardening treatment.

The load applied to the tongue piece 1 is, specifically,
As shown in FIG. 1, the load is applied when thermal expansion and contraction occurs in the longitudinal direction of the seam welded portion of the enclosure constructed by seam welding a plurality of coated metal materials 5, 5,.

The metal plate constituting the tongue piece 1 has a higher mechanical strength than the metal plate forming the covering metal member 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.

The reinforcing member 2 is formed so as to cover the lower end of the tongue piece 1a of the tongue piece body 1 and the substantially entire upper and lower surfaces of the bottom piece 1b. The reinforcing member 2 is also formed continuously at a portion where it does not overlap with the tongue piece 1, and is configured as a mounting piece 2c. Specifically, as shown in FIGS. 2 and 3, a folded piece 2 b is formed in a flat C-shape on the fixed bottom 2 a, and further,
A mounting piece 2c is continuously formed on the fixed bottom 2a, and one mounting hole 3 is formed at the mounting piece 2c.

Further, as shown in FIG. 3, a rising piece 2d is formed perpendicularly to the folded piece 2b from the edge of the folded piece 2b. The mounting piece 2c is often folded and formed of two pieces.

As shown in FIG. 3, the bottom piece 1 of the tongue piece 1 is sandwiched between the fixed bottom 2a and the folded piece 2b so as to be sandwiched between the fixed bottom 2a and the folded piece 2b of the reinforcing member 2.
b is inserted and fixed. For fixing the tongue piece 1 and the reinforcing member 2, a spot welding means is specifically used.

One mounting hole 3 exists on the tongue 1a of the tongue 1 as shown on the line. Specifically, the mounting hole 3 is formed on the mounting piece 2c described above.

The above-mentioned line of the tongue piece 1a refers to an extension of the flat tongue piece 1a in the lateral direction of the plane, and more specifically, a linear cross section (in the plane of the tongue piece 1a). As shown in FIG. 4, this is on an extension of the suspension A in a cross section as viewed from above.

The mounting hole 3 is formed on the reinforcing member 2 or the reinforcing member 2 and the bottom piece 1b of the tongue piece body 1 so as to be on the line of the tongue piece 1a.

[0022]

As shown in FIG. 1, a coating metal material 5 is placed on the top or side of a base 4 made of steel frame or reinforced concrete or the like, and an appropriate space is provided in the longitudinal direction of the one side rising portion 5b. At this point, a large number of the hooks A of the present invention are fixed.

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

Next, an adjacent coated metal material 5 is placed adjacent to the already mounted coated metal material 5, 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,.

The coating metal material 5 is long in the longitudinal direction,
Side rising portions 5b, 5b are formed on both sides in the width direction of the main plate 5a.

The side upstanding portion 5b is used when seam welding is performed in the longitudinal direction with the adjacent coated metal members 5, 5 arranged side by side.
The opposite side rising portions 5b are seam-welded to each other.

[0028]

According to the present invention, a tongue piece 1 composed of 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 1b is composed of a reinforcing material 2 covering the entire upper and lower surfaces, and the reinforcing material 2 is also formed continuously at a portion where the tongue piece 1 does not overlap.
In a continuous portion of the bottom piece 1b, a mounting hole 3 is formed at one location so as to be substantially on the line of the tongue piece 1a, and the member as the tongue piece body 1 and the reinforcing material 2 can be seam welded. First, the covering metal materials 5 and 5 are formed by using a suspension having a mechanical strength larger than that of the metal plate material forming the material 5.
Can be fixed with a fixing tool 6 such as a single drill screw to fix the coated metal material 5 to the base material 4. Second, the coated metal material 5 can be fixed to the base material. There are various effects such as the fact that this can be fixed very firmly to fix to the part 4.

These effects will be described in detail. In the hook A of the present invention, since the mounting hole 3 is formed substantially on the line of the tongue piece 1a, the tongue piece 1a is subject to a tensile load or the like depending on the thermal expansion and contraction direction of seam welding. When an external force is applied, the tongue piece 1a moves around the three mounting holes, and the thermal expansion and contraction direction of the seam welding point and the line connecting the tongue piece 1a and the one mounting hole 3 are always in the same direction. This makes it possible to favorably cope with the direction of thermal expansion and contraction (see FIG. 4).

As described above, only one mounting hole 3 is provided.
Since only one fixing tool 6 is required, simple and quick construction can be performed.

Next, the tongue piece 1 forming the suspension A of the present invention
Since the metal plate material of (1) has a mechanical strength such as tensile strength and shear strength larger than that of the metal plate material forming the coated metal material 5, the metal sheet material of the adjacent coated metal material 5, 5 Thermal expansion and contraction due to outside air occurs, and the tongue 1a of the hook A
When a tensile force and a shearing force act on the tongue 1a, the tongue piece 1a of the slinger A is sufficiently strong within its proof strength against the tensile force and the shearing force. Despite being a completely fixed type and not a slide type, it is possible to provide an extremely strong attachment (see FIG. 5).

Next, the present invention has an extremely simple structure as compared with a slide type suspension, and is suitable for mass production in its manufacture, and can be provided at a low price. It is.
