[0001]

[Industrial application]

 The present invention relates to a hanger that does not move in response to thermal expansion and contraction of a covered metal enclosure by seam welding and has a very simple structure.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, a coated metal enclosure in which a coated metal material (mainly a stainless steel material) is seam-welded to the inner and outer surfaces of a structure to perform a watertight and airtight construction has been actively researched and developed.

In order to attach the rising portion of the coated metal material to the structure, conventionally, a movable suspension having a tongue piece that is appropriately movable in response to thermal expansion and contraction of the coated metal material has been often used in the past.

This is because the thermal expansion and contraction copes with the thermal stress strain of the coated metal material and thus the coated metal envelope.

[0005]

[Problems to be solved by the device]

 The sliding type suspension has a drawback that the structure of the sliding portion of the tongue piece tends to be complicated, the number of manufacturing processes increases, and the cost becomes expensive.

[0006]

[Means for Solving the Problems]

 Then, as a result of earnestly researching to solve the above-mentioned problems, the inventor has found that the present invention provides a tongue piece including a tongue piece and a bottom piece formed into a substantially L-shaped thin plate, and a bottom piece portion of the tongue piece body. Which is made of a reinforcing material covering the tongue piece and at least two or more mounting holes are formed in the bottom piece of the tongue body and the reinforcing material, and these members are mechanically stronger than a metal plate material which forms a covered metal material capable of seam welding. By using a suspension with increased strength, it does not move in response to thermal expansion and contraction of the sheathed metal enclosure due to seam welding, and the configuration is extremely simple, solving the above problems and achieving the purpose. It was done.

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

The tongue piece 1 is made of spring steel or stainless steel from the viewpoint of strength, corrosion resistance, etc., and can be seam welded to another metal plate and retains watertightness after welding. It has the conditions that can be done.

Further, the tongue piece 1 has durability against external force such as shear load and bending load, and further, to improve the mechanical strength such as tensile strength. The metal material forming the is heat-treated to improve the properties of the metal.

There are various heat treatment means for improving the mechanical strength, and 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, the seam welding of the outer body which is constructed by seam welding a plurality of coated metal materials 5, 5, ... Location This is the load exerted when thermal expansion and contraction occur along the longitudinal direction.

As the metal plate material forming the tongue piece 1, one having a larger mechanical strength such as tensile strength and shear strength than the metal plate material forming the coated metal material 5 is used.

Therefore, the load generated on the suspension A by thermal expansion generated in the longitudinal direction of the seam welded portions of the adjacent coated metal materials 5 and 5 is regarded as shear load and bending load on the tongue piece 1 of the suspension A. 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 rising piece 2b formed from the edge of a flat piece 2a, and the thickness of the metal material forming the tongue piece 1 is increased. It is formed thicker than Sasa.

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

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

The bottom piece 1 b of the tongue piece 1 and the flat piece 2 a of the reinforcing member 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 mounting holes 3 and 3 have a constant spacing.

As a concrete example of the place where the attachment hole 3 is formed, as shown in FIG. 4, in the bottom piece 1b formed in a rectangular shape, the bottom piece 1b is opposed to the edge where the tongue piece 1a is formed. Two mounting holes 3 and 3 are formed in a line toward the end.

The attachment holes 3 may be formed in a triangular shape when formed at three locations on the bottom piece 1b of the tongue piece 1 and the flat piece 2a of the reinforcing member 2.

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

As shown in FIG. 2, the side rising portions 5b are arranged such that when adjacent covering metal materials 5 and 5 are provided side by side and seam welding is performed in the longitudinal direction, the facing side rising portions 5b and 5b are opposed to each other. Seam welding is used.

[0025]

[Action]

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

When fixing the suspension A to the base material 4, fixing tools 6, 6, ... Such as drill screws and anchor bolts are used in the plurality of mounting holes 3 of the suspension A.

[0029]

[Effect of the device]

 According to the present invention, the tongue piece body 1 is composed of a tongue piece 1a and a bottom piece 1b which are formed into a substantially L-shaped thin plate, and the reinforcing material 2 covering the bottom piece 1b of the tongue piece body 1 is provided. At least two or more mounting holes 3, 3, ... Are drilled in the bottom piece 1b and the reinforcing material 2 of 1, and the mechanical strength is higher than that of the metal plate material forming the covered metal material 5 capable of seam welding these members. First, in the enclosure formed of the covering metal materials 5 and 5, the covering metal material 5 is fixed to the base material 4 to be extremely strong by using the enlarged suspension. It can be fixed and can be made extremely excellent in durability after construction. Secondly, it has various effects such as being extremely simple in structure and being provided at a low price.

To explain these effects in detail, the metal plate material of the tongue piece 1 forming the suspension A of the present invention has a higher tensile strength, shear strength, etc. than the metal plate material forming the coated metal material 5. Since the mechanical strength of the tongue 1a of the suspension A is increased, thermal expansion and contraction occurs due to the outside air at the seam welding points of the adjacent coated metal materials 5 and 5, so that the tensile force and the shearing force are applied to the tongue 1a of the suspension A. When the tongue piece 1 of the suspension A is sufficiently within its proof strength against the pulling force and the shearing force when the suspension A is actuated, the suspension A is of a completely fixed type and of a slide type. Notwithstanding, it can be a very strong attachment (see Fig. 5).

Next, the suspension A of the present invention is composed of the bottom piece 1b of the tongue piece 1 and the reinforcing material 2, and the bottom piece 1b and the reinforcing material 2 have at least two or more mounting holes 3, 3, ... Since the tongue body 1 is subjected to a rotation moment around the bottom piece 1b of the suspension A as a center, the mounting holes 3, 3, ... By fixing the suspension A to the base portion 4 with a fixing tool 6 such as a bolt, a nut or a screw, it is possible not only to sufficiently cope with the rotational moment in terms of strength, but also the bottom piece 1b. By being strongly reinforced by the reinforcing material 2, it is possible to prevent cracks between the mounting holes 3, 3, ... And the fasteners 6, 6 ,.

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 different from the slide type suspension. The structure is extremely simple, and it is suitable for mass production and can be provided at a low price.
