DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coated metal envelope which is formed by using a long length of stainless steel for coating and is formed by seam welding. The present invention relates to an envelope capable of responding to thermal expansion and contraction in the longitudinal direction (seam welding direction) of a material very well.

[0002]

2. Description of the Related Art Conventionally, a coated metal enclosure formed by seam welding a plurality of stainless steel materials for coating (mainly stainless steel) to each other through a suspension fixed to a base portion and performing watertight and airtight sealing. Has been actively researched and developed. In order to attach the plurality of covering stainless steels to a structure in parallel, a movable hook having a tongue that can be appropriately moved according to the thermal expansion and contraction of the covering stainless steels is conventionally used. There were many. The movable suspender is used to cope with the thermal expansion and contraction of the covering stainless steel in the longitudinal direction (seam welding direction) by thermal expansion and contraction.

[0003]

However, in the case of a large-sized coated metal enclosure, in order to make it have an orderly appearance, the coating stainless steel is made long and the coating stainless steels are longitudinally separated from each other. If the coated metal enclosure is constructed without joints, each coating stainless steel will constantly expand and contract due to the outside air temperature. The amount of thermal expansion and contraction in the longitudinal direction of the coating stainless steel becomes larger as the coating stainless steel becomes longer, and the above-mentioned slide type movable suspension is used. As described above, not only the structure is complicated and expensive, but also the external force is relatively weak, and when a negative pressure is applied to the coated metal enclosure by a strong wind, there is a risk that the movable suspension may be broken.

Further, in the case where a covered metal envelope is formed by seam welding using a large number of short fixed hanging members, the large number of fixed hanging members are fixed to a base portion such as a purlin, a trunk edge, or the like. However, since the number of the short fixed hanging members becomes large, the mounting work is extremely troublesome, the number of construction days becomes long, and the construction cost becomes high. further,
The short fixed suspension, like the movable suspension, is relatively easily deformed when subjected to thermal expansion and contraction in the longitudinal direction of the covering stainless steel, so it is difficult to obtain the fixing effect. It was detached from the part or cracked, leading to breakage.

[0005] In addition, the covering stainless steel constituting the covering metal enclosure needs to be provided with a large expansion for absorbing thermal expansion or contraction or cut off at every longitudinal length of about 30 m or less. . Such large-sized expansions often use the same stainless steel for covering, but when constructing a building, it is necessary to adopt a structure that provides such large-sized expansions. It is a hindrance to designing. For this purpose, a large-sized coated metal enclosure is constructed while taking various measures. However, if excessive measures are taken, cracking of the coated stainless steel may occur.

[0006]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that the present invention provides a structural member composed of a plurality of grooved steels on a beam at appropriate intervals. A double structural material portion fixed substantially orthogonally to the beam material and having a close contact structure such that the opening sides of the two structural materials face each other at regular intervals of the plurality of structural materials. A hard base plate is arranged on the structural material, and the hard base plate constitutes a base portion whose both ends are large enough to be placed between the adjacent double structural material portions. Seam welding is performed between the rising portions on both sides of the metal covering stainless steel that can be seam welded, and a restraining hook having an appropriate length is provided in the seam welding direction and at predetermined intervals over a plurality of structural materials. A plurality of stainless steel materials for covering are arranged through the restraining suspenders. In addition to being fixed to the base portion, the restraining hanger is fixed to a plurality of structural members via a restraining hanger fixing tool that penetrates the hard ground plate, and the predetermined distance is set between adjacent restraints for fixing the restraining hanger. By using a coated metal enclosure that is less than the spacing of the anchors for the hooks, a large-sized coated metal enclosure made of a long coating stainless steel can be constructed, and the length of the coating stainless steel in the longitudinal direction can be reduced. While being able to respond very well to thermal expansion and contraction, the construction can be performed extremely efficiently, and after the construction can be made a very strong coated metal envelope, solving the above problems,
It has achieved its purpose.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The coating stainless steel 1 is made of a thin metal (for example, about 0.2 mm to 1 mm) made of a seam weldable metal, and specifically, stainless steel (SUS304 or the like) is used. In this embodiment, a titanium alloy is used. As shown in FIGS. 1, 3 and the like, the covering stainless steel 1 has side rising portions 1b for seam welding formed on both sides in the width direction of a flat main plate 1a.

Of the base A, and another coating stainless steel 1 is placed adjacent to the coating stainless steel 1, The opposite side rising portions 1b, 1b of the covering stainless steel 1, 1 are brought into contact with each other, the upper end portions of the both side rising portions 1b, 1b are seam welded, and further between the both side rising portions 1b, 1b. The tongue piece 9 of the restraining suspender B, which will be described later, is sandwiched between and fixed to the base A. The seam welded portion between the both side rising portions 1b, 1b is referred to as a joint portion 1A.

As shown in FIGS. 1 to 3, a plurality of structural members 4, 4,... Are arranged in parallel in the base portion A, and are used as a purlin, a trunk, and the like. As a specific embodiment of the structural member 4, a lip channel steel is used. In an embodiment in which a lip channel steel is used for the structural material 4 and a purlin and a hull are formed, as shown in FIGS. Structural materials 4,4
Are arranged in parallel with each other, and the two structural members 4, 4 are in close contact with each other at regular intervals to form a double structural member 4A.

As shown in FIGS. 3 to 5, the double structural member 4A is composed of two structural members 4 and 4 such that the opening sides face outward. The distance between 4A and 4A is such that one hard base plate 5 can be placed (see FIGS. 2 and 3). The beam 6 is often made of an I-beam or an H-beam. At this time, the structural members 4 such as the purlin and the rim are fixed to the beam members 6 through the connecting piece members 8 such as L-shaped steel.

The rigid base plate 5 placed and laid on the plurality of structural members 4, 4,... It has a strength enough to withstand a load caused by “pricking” acting in a direction perpendicular to the axial direction of the tool 7, that is, a prying resistance. The prying resistance of the stainless steel for coating 1,1
Is generated when the joint portion 1A thermally expands and contracts in the longitudinal direction.

The joint resistance 1A is such that the restraint suspension B and the restraining fasteners 7, 7,... It acts to resist the force that attempts to enlarge the through hole, preventing the through hole from expanding. As a specific example of the hard base plate 5 having such properties, a rigid base plate 5 having a thickness of 20 mm or more and a flexural breaking strength according to JIS A1408 of about 200
Kgf or higher high pressure wood wool cement board or JIS A5417
Is preferred.

Further, the hard base plate 5 has a high plane rigidity. Its plane rigidity is tensile in the plane direction,
It has a large resistance to compression and shearing, and is extremely difficult to deform due to external forces generated in the plane direction. That is, the hard base plate 5 has an extremely large value of the breaking load. Specific examples of the hard base plate 5 having such properties include JIS in addition to the performance described in the above example.
The deflection of the center of the span due to A1408 is 200kg
A high-pressure wood wool cement board or a hard wood chip cement board having a rigidity of about 8 mm or less at f is preferable.

The restraining suspender B has a tongue piece 9 integrally formed on a mounting bottom 10 and a substantially L-shaped cross section orthogonal to the longitudinal direction. Both ends in the longitudinal direction of the mounting bottom portion 10 of the restraining suspender B have a length that can be placed at least over two adjacent structural members 4, 4. At least both end portions of the bottom 10 are fixed on the structural material 4 via the hard base plate 5 by the fixtures 7 for restraint suspenders (see FIGS. 4 and 6). The fixture 7 for restraint suspension is specifically a drill screw, which penetrates through the hard base plate 5 and is screwed to the structural material 4 supporting the hard base plate 5 from below.

Further, the restraining suspenders B are arranged along the joints 1A of the adjacent covering stainless steels 1,1. That is, a predetermined length of space is provided between adjacent restraining suspenders B, B,... Along the seam welding direction to form a predetermined space L. To absorb the thermal expansion and contraction of the joint 1A. The length of the predetermined interval L does not exceed about 1.3 m, and based on the predetermined interval L, the predetermined interval L is equal to a plurality of fixing hooks for fixing the respective constraint hooks B. In the fixtures 7, 7,..., The distance between the adjacent fixtures 7 for restraint suspenders is smaller than or equal to the dimension.
More specifically, the predetermined distance L is determined by the fixture 7 for the restraint suspender,

The rigidity against tension and compression in the surface direction is large, and the structural members 4, 4,... The position does not easily change due to expansion and contraction.

Therefore, the mounting position of the base portion A does not shift due to the thermal expansion and contraction of the joint portion 1A in the longitudinal direction due to the plurality of covering stainless steels 1 and 1. The thermal expansion and contraction is absorbed by the portion of the predetermined interval L existing between the restraining suspenders B adjacent to each other along the joint 1A.

In the thermal expansion and contraction of the joint 1A, the joint 1A is bent at a predetermined distance L when it is in the stretched state, and the joint 1A maintains a substantially linear shape at the position of the restraining suspender B. FIG. 8 shows a state in which thermal expansion and contraction has not yet occurred in FIG. 8, and FIG. 9 shows a state in which expansion due to thermal expansion and contraction has occurred in the joint portion 1A and bending is absorbed at a predetermined interval L. It is shown. Fig. 10 shows the joint 1
It is an enlarged view of the state which absorbed the bending by the thermal expansion and contraction of A.

When the joint 1A is in a contracted state,
The joint portion 1A shrinks in the longitudinal direction at a predetermined interval L, and the restraining suspenders B, B on both sides of the predetermined interval L exert a resistance force against the shrinkage. 12 and 13).

The pitch of the fixing members 7, 7, ... is preferably approximately 60 cm. Further, as an embodiment of the mounting bottom 10 of the restraining suspender B, as shown in FIG. 16, a washer piece 10b having substantially the same area as the bottom plate 10a is formed by folding back above the edge of the bottom plate 10a. Then, the bottom plate 10a and the washer pieces 10b are fixed together on the base portion A by the restraining fixture 7 for restraint hooks. With such a structure, the bottom plate 10a of the mounting bottom portion 10 is pressed down from above by the washer pieces 10b via the restraining fixtures 7 for the restraint, and a load such that the restraining hook B is pulled upward. 17, it is possible to prevent the bottom plate 10a from being greatly separated from the base portion A as shown in FIG.

As another embodiment of the mounting bottom 10 of the restraining suspender B, an auxiliary piece 10c is formed by folding back on the lower surface side of the bottom plate 10a of the mounting bottom 10. Fine adjustment to a position slightly higher than the base portion A is possible. Further, the washer plate 1 is provided above the mounting bottom 10.
As shown in FIG. 19, the washer plate 13 may have the same length as the length of the restraining suspender B, or may be provided only at the mounting position of the restraining fixture 7 for the restraining hook. Examples of a type formed in a square shape exist as examples.
